Ladies and Gentlemen:

Sundance Energy Australia Limited, an Australian corporation (the “Company”), confirms its agreement with Xxxxx Fargo Securities, LLC (“Xxxxx Fargo”), Canaccord Genuity Inc. (“Canaccord”), UBS Securities LLC (“UBS”) and each of the other Underwriters named in Exhibit A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Xxxxx Fargo, Canaccord and UBS are acting as representatives (in such capacity, the “Representatives”) with respect to the sale by the Company of a total of American Depositary Shares (“ADSs”) each representing ordinary shares, no par value (the “Ordinary Shares”), of the Company (such ADSs to be sold by the Company being referred to herein as the “Initial Securities”), and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of Initial Securities set forth in Exhibit A, and with respect to the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of additional ADSs to cover over-allotments, if any. The Initial Securities to be purchased by the Underwriters and all or any part of the ADSs subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.” The ADSs will be evidenced by American Depositary Receipts (“ADRs”) issued pursuant to a Deposit Agreement, to be dated as of the Closing Date (as defined herein) (the “Deposit Agreement”), by and among the Company, The Bank of New York Mellon, as depositary (the “Depositary”), and all holders and beneficial owners of ADSs issued thereunder. The Ordinary Shares to be issued in connection with, and represented by, the ADSs are hereinafter referred to as the “Underlying Securities.” Certain terms used in this Agreement are defined in Section 15 hereof.

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus dated , 2014 in accordance with the provisions of Rule 430A and Rule 424(b) and the Company has previously advised the Representatives of all information (financial and other) that will be set forth therein. Such prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), is herein called the “Prospectus.”

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each Underwriter as of the date hereof, as of the Applicable Time, as of the Closing Date referred to in Section 2(c) hereof, and as of each Option Closing Date (if any) referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(1) Compliance with Registration Requirements. The offer and sale of the Underlying Securities have been duly registered under the 1933 Act pursuant to the Registration Statement. Each of the Initial Registration Statement and any post-effective amendments thereto have been declared effective under the 1933 Act and any Rule 462(b) Registration Statement has become effective under the 1933 Act or, not later than 8:00 a.m. (New York City time) on the business day immediately after the date of this Agreement, will become effective under the 1933 Act, and no stop order suspending the effectiveness of the Initial Registration Statement or any Rule 462(b) Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with. The Initial Registration Statement was initially filed (on a confidential basis) with the Commission on October 18, 2013.

(2) Registration Statement, Prospectus and Disclosure at Time of Sale. At the respective times that the Initial Registration Statement, any Rule 462(b) Registration Statement and any amendments to any of the foregoing were declared or became effective, as the case may be, and at the Closing Date (and, if any Option Securities are purchased, at the applicable Option Closing Date), the Initial Registration Statement, any Rule 462(b) Registration Statement and any amendments to any of the foregoing (i) complied and will comply in all material respects with the requirements of the 1933 Act and applicable 1933 Act Regulations and (ii) 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 statement made, in light of the circumstances in which they were made, not misleading.

At the respective times the Prospectus or any amendment or supplement thereto was filed pursuant to Rule 424(b) or issued, at the Closing Date (and, if any Option Securities are purchased, at the applicable Option Closing Date), and at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by applicable law to be delivered in connection with sales of Securities (whether to meet the requests of purchasers pursuant to Rule 173(d) or otherwise), neither the Prospectus nor any amendments or supplements thereto included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

As of the Applicable Time (except in the case of clause (y) below) and as of each time prior to the Closing Date that an investor agrees (orally or in writing) to purchase or, if applicable, reconfirms (orally or in writing) an agreement to purchase any Securities from the Underwriters, neither (w) any Issuer General Use Free Writing Prospectuses, if any, issued at or prior to the Applicable Time, the Pre-Pricing Prospectus as of the Applicable Time and the information, if any, included on Exhibit H hereto, all considered together (collectively, the “General Disclosure Package”), nor (x) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, nor (y) any Issuer General Use Free Writing Prospectus issued subsequent to the Applicable Time, when considered together with the General Disclosure Package, included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

Each preliminary prospectus and the Prospectus and any amendments or supplements to any of the foregoing filed as part of the Registration Statement or any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, or delivered to the Underwriters for use in connection with the offering of the Securities, complied when so filed or when so delivered, as the case may be, in all material respects with the 1933 Act and applicable 1933 Act Regulations.

The representations and warranties in the preceding paragraphs of this Section 1(a)(2) do not apply to statements in or omissions from the Registration Statement, any preliminary prospectus, the Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement to any the foregoing made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters as aforesaid consists of the information described as such in Section 6(b) hereof.

At the respective times that the Initial Registration Statement, any Rule 462(b) Registration Statement or any amendment to any of the foregoing were filed and as of the date of this Agreement, the Company was not and is not an “ineligible issuer” as defined in Rule 405, and without limitation to the foregoing, the Company has at all relevant times met, meets and will at all relevant times meet the requirements of Rule 164 for the use of a free writing prospectus (as defined in Rule 405) in connection with the offering contemplated hereby.

The copies of the Initial Registration Statement and any Rule 462(b) Registration Statement and any amendments to any of the foregoing and the copies of each preliminary prospectus, each Issuer Free Writing Prospectus that is required to be filed with the Commission pursuant to Rule 433 and the Prospectus and any amendments or supplements to any of the foregoing, that have been or subsequently are delivered to the Underwriters in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise) were and will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T. For purposes of this Agreement, references to the “delivery” or “furnishing” of any of the foregoing documents to the Underwriters, and any similar terms, include, without limitation, electronic delivery.

The Company has made available a “bona fide electronic road show” (as defined in Rule 433(h)) in compliance with Rule 433(d)(8)(ii) such that no filing with the Commission of any “road show” (as defined in Rule 433(h)) is required in connection with the offering of the Securities.

Each Issuer Free Writing Prospectus (if any), as of its issue date and at all subsequent times through the completion of the public offering and sale of the Securities, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any preliminary prospectus or the Prospectus that has not been superseded or modified.

(3) F-6 Registration Statement. A registration statement on Form F-6 (File No. 333-193044) with respect to the ADSs has (i) been prepared by the Company in conformity with the requirements of the 1933 Act and the applicable 1933 Act Regulations, (ii) been filed with the Commission under the 1933 Act, and (iii) become effective under the 1933 Act. Copies of such registration statement have been delivered by the Company to you as the Representatives. As used in this Agreement, “F-6 Registration Statement” means such registration statement, as amended at the time it became effective under the 1933 Act, including all exhibits thereto. The Commission has not issued any order suspending the effectiveness of the F-6 Registration Statement, and no proceeding for that purpose has been instituted or, to the Company’s knowledge, threatened by the Commission. The F-6 Registration Statement, at the time it became effective under the 1933 Act, (i) conformed in all material respects to the requirements of the 1933 Act and the applicable 1933 Act Regulations and (ii) and did not, as of the applicable effective date, contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statement made, in light of the circumstances in which they were made, not misleading.

(4) Emerging Growth Company. From the time of the initial confidential submission of the Company’s draft Registration Statement on Form F-1 to the Commission (or, if earlier, the first date on which the Company engaged directly or through any person authorized to act on its behalf in any Testing-the-Waters Communication) through the Applicable Time, the Company has been and is an “emerging growth company,” as defined in Section 2(a) of the 1933 Act (an “Emerging Growth Company”).

(5) Testing-the-Waters Communications. The Company (i) has not alone engaged in any Testing-the-Waters Communication and (ii) has not authorized anyone other than the Representatives to engage in Testing-the-Waters Communications. The Company confirms that it may, upon request, authorize the Representatives to act on its behalf in undertaking Testing-the-Waters Communications. The Company has not distributed any Written Testing-the-Waters Communications.

(6) Foreign Private Issuer. The Company is a “foreign private issuer” within the meaning of Rule 405 under the 1933 Act.

(7) Independent Accountants. The accountants who certified the financial statements and any supporting schedules included in the Registration Statement, the General Disclosure Package and the Prospectus are independent public accountants with respect to the Company and its subsidiaries within the applicable rules and regulations of the Commission and PCAOB, and as required by the 1933 Act.

(8) Financial Statements. The financial statements of the Company included in the Registration Statement, the General Disclosure Package and the Prospectus, together with the related schedules (if any) and notes thereto, present fairly in all material respects the financial position of the Company and its consolidated subsidiaries at the dates indicated and the results of operations, changes in stockholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; the financial statements of any other entities or businesses included in the Registration Statement, the General Disclosure Package or the Prospectus, together with the related schedules (if any) and notes, present fairly in all material respects the financial position of each such entity or business, as the case may be, and its consolidated subsidiaries (if any) at the dates indicated and the results of operations, changes in stockholders’ (or other owners’) equity and cash flows of such entity or business, as the case may be, and its consolidated subsidiaries, if any, for the periods specified.

The supporting schedules, if any, included in the Registration Statement present fairly, in all material respects and in accordance with IFRS, the information required to be stated therein. The information in the Pre-Pricing Prospectus and the Prospectus under the captions “Summary Historical and Pro Forma Consolidated Financial Data” and “Selected Historical and Pro Forma Consolidated Financial Data” presents fairly in all material respects the information shown therein and has been compiled on a basis consistent with that of the audited financial statements of the Company included in the Registration Statement, the General Disclosure Package and the Prospectus. The pro forma financial statements and the related notes thereto included in the Registration Statement, the General Disclosure Package and the Prospectus present fairly in all material respects the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements and have been properly compiled on the bases described therein, and the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions and circumstances referred to therein. The information appearing in the Pre-Pricing Prospectus and the Prospectus under the captions “Summary Historical and Pro Forma Consolidated Financial Data” and “Selected Historical and Pro Forma Consolidated Financial Data” present fairly in all material respects the information shown therein and has been compiled on a basis consistent with that of the pro forma financial statements included in the Registration Statement, the General Disclosure Package and the Prospectus. All “non-IFRS financial measures”, if any, contained in the Registration Statement, the General Disclosure Package and the Prospectus comply with Item 10(e) of Regulation S-K of the Commission, to the extent applicable.

(9) Independent Reserve Engineers. Netherland, Xxxxxx & Associates, Inc. (“NSA”), whose reserve evaluations are referenced or appear, as the case may be, in the Registration Statement, the General Disclosure Package and Prospectus were, as of June 30, 2013, and are, as of the date hereof, independent engineers with respect to the Company in accordance with guidelines established by the Commission; and the historical information underlying the estimates of the reserves of the Company supplied by the Company to NSA for the purposes of preparing the reserve reports of the Company referenced in the Registration Statement, the General Disclosure Package and Prospectus (the “Reserve Reports”), including, without limitation, production volumes, sales prices for production, contractual pricing provisions under oil or gas sales or marketing contracts or under hedging arrangements, costs of operations and development, and working interest and net revenue information relating to the Company’s ownership interests in properties, was true and correct in all material respects on the date that each such Reserve Report was prepared in all material respects in accordance with Commission

rules and customary industry practices. Other than normal production of the reserves, product price fluctuations, and fluctuations of demand for such products, and except as disclosed in the Registration Statement, the General Disclosure Package and Prospectus, the Company is not aware of any facts or circumstances that would reasonably be expected to result in a Material Adverse Effect (as defined below) in the reserves in the aggregate, or the aggregate present value of the future net cash flows therefrom as described in the Registration Statement, the General Disclosure Package and Prospectus and as reflected in the Reserve Reports.

(10) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), (A) there has been no material adverse change or any development that could reasonably be expected to result in a material adverse change in the condition (financial or other), results of operations, business, properties, management or prospects of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business (in any such case, a “Material Adverse Effect”); (B) except as otherwise disclosed in the General Disclosure Package and the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), neither the Company nor any of its subsidiaries has incurred any liability or obligation or entered into any transaction or agreement that, individually or in the aggregate, is material with respect to the Company and its subsidiaries, taken as a whole, and neither the Company nor any of its subsidiaries has sustained any loss or interference with its business or operations from fire, explosion, flood, earthquake or other natural disaster or calamity, whether or not covered by insurance, or from any labor dispute or disturbance or court or governmental action, order or decree which could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect; and (C) there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its capital stock.

(11) Good Standing of the Company. The Company has been duly organized and is validly existing as a corporation under the laws of Australia and has power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into and perform its obligations under this Agreement. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except (solely in the case of jurisdictions other than Australia) where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Effect.

(12) Good Standing of Subsidiaries. Each subsidiary of the Company has been duly organized and is validly existing as a corporation, limited or general partnership or limited liability company, as the case may be, in good standing under the laws of the jurisdiction of its organization, has power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package or the Prospectus and is duly qualified as a foreign corporation, limited or general partnership or limited liability company, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Effect. Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, all of the issued and outstanding shares of capital stock of each such subsidiary that is a corporation, all of the issued and outstanding partnership interests of each such subsidiary that is a limited or general partnership and all of the issued and outstanding limited liability company interests, membership interests or other similar interests of each such subsidiary that is a limited liability company have been duly authorized and validly issued, are fully paid and (except in the case of general partnership interests) non-assessable and are owned by the Company, directly or through subsidiaries, free and clear of any Lien (except for Liens arising under the Existing Credit Agreements). None of the issued and outstanding shares of capital stock of any such subsidiary that is a corporation, none of the issued and outstanding partnership interests of any such subsidiary that is a limited or

The issued and outstanding capital stock of the Company as of the first Option Closing Date (assuming on that date the Underwriters have exercised the option described in Section 2(b) in full) will be Ordinary Shares, which includes an aggregate of Ordinary Shares represented by ADSs (except for subsequent issuances of Ordinary Shares, if any, pursuant to this Agreement or pursuant to the Company’s equity incentive plans described in the Pre-Pricing Prospectus and the Prospectus under the caption “Management-Remuneration”). The issued and outstanding Ordinary Shares have been validly issued, fully paid and were issued in compliance with all applicable foreign, state and federal securities and “blue-sky” laws; and none of the outstanding Ordinary Shares was issued in violation of any preemptive rights, rights of first refusal or other similar rights of any securityholder of the Company or any other person.

(14) Authorization of Agreement. This Agreement has been duly authorized, executed and delivered by the Company.

(15) Authorization of Deposit Agreement. The Deposit Agreement has been duly authorized, and, when executed and delivered by the Company and, assuming due authorization, execution and delivery by the Depositary, will constitute a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, subject to (i) the effects of bankruptcy, insolvency, reorganization and similar laws of general applicability relating to or affecting creditors’ rights and (ii) to general equitable principles (whether considered in a proceeding in equity or at law). Upon execution and delivery by the Depositary of the ADRs evidencing the Securities against deposit of the Underlying Securities in respect thereof in accordance with the provisions of the Deposit Agreement and upon payment by the Underwriters for the Securities evidenced thereby in accordance with the provisions of this Agreement, the ADSs evidenced by such ADRs will be duly and validly issued, and the persons in whose names the ADRs are registered will be entitled to the rights specified therein and in the Deposit Agreement. The Deposit Agreement conforms in all material respects to the description thereof contained in the Registration Statement, the General Disclosure Package and the Prospectus.

(16) Authorization of the Securities. The Underlying Securities to be issued by the Company under this Agreement have been duly authorized for issuance to the Underwriters pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement against payment of the consideration set forth herein, will be validly issued and fully paid. No holder of the Securities is or will be subject to personal liability by reason only of being such a holder; and the issuance and sale of the Securities to be sold by the Company under this Agreement are not subject to any preemptive rights, rights of first refusal or other similar rights of any securityholder of the Company or any other person.

(17) Description of the Ordinary Shares. The Ordinary Shares and the Company’s Organizational Documents conform in all material respects to the respective statements relating thereto contained in the Registration Statement, the General Disclosure Package and the Prospectus and such statements conform to the rights set forth in the respective instruments and agreements defining the same.

(18) Description of the ADSs. The ADSs conform in all material respects to the description thereof contained in the Registration Statement, the General Disclosure Package and the Prospectus. Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there are no limitations on the rights of holders of Underlying Securities, ADSs or ADRs evidencing the ADSs to hold or vote or transfer their respective securities.

(19) Absence of Defaults and Conflicts. Neither the Company nor any of its subsidiaries is in violation of its Organizational Documents or in default in the performance or observance of any obligation, agreement, covenant or condition contained in any Company Document, except (solely in the case of Company Documents other than Subject Instruments) for such defaults that would not, individually or in the aggregate, result in a Material Adverse Effect and would not materially adversely affect the consummation of the transactions contemplated herein. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the Registration Statement, the General Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Pre-Pricing Prospectus and the Prospectus under the caption “Use of Proceeds”) and compliance by the Company with its obligations under this Agreement do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default, Termination Event or Repayment Event under, or result in the creation or imposition of any Lien upon any property or assets of the Company or any of its subsidiaries pursuant to, any Company Documents, except (solely in the case of Company Documents other than Subject Instruments) for such conflicts, breaches, defaults or Liens that would not, individually or in the aggregate, result in a Material Adverse Effect or materially adversely affect the consummation of the transactions contemplated herein, nor will such action result in any violation of (i) the provisions of the Organizational Documents of the Company or any of its subsidiaries or (ii) any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any of its subsidiaries or any of their respective assets, properties or operations, including the ASIC and the rules of any securities exchange, including the Nasdaq Global Select Market and the ASX.

(20) Absence of Labor Dispute. No labor dispute with the employees of the Company or any subsidiary of the Company exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of the principal suppliers, manufacturers, customers or contractors of the Company or any of its subsidiaries which might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

(21) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against or affecting the Company or any of its subsidiaries which is required to be disclosed in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus (other than as disclosed in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus), or which might reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect or to materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations under this Agreement. The aggregate of all pending legal or governmental proceedings to which the Company or any of its subsidiaries is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, the Pre-Pricing Prospectus and the Prospectus, including ordinary routine litigation incidental to the business, would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

(22) Accuracy of Descriptions and Exhibits. The information in the Pre-Pricing Prospectus and the Prospectus under the captions “Risk Factors—Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of a significant portion of our ordinary shares or ADSs,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” “Business—Regulation of the Oil and Natural Gas Industry,” “Business—Environmental, Health and Safety Regulation,” “Business—Legal Proceedings,” “Management—Remuneration,” “Related Party Transactions,” “Description of Share Capital,” “Description of American Depositary Shares,” “Shares Eligible for Future Sale,” “Taxation,” the fifth through eighth paragraphs of “Underwriting” and “Enforceability of Civil Liabilities,” and the information in the Registration Statement under Items 6 and 7, in each case to the extent that it constitutes matters of law, summaries of legal matters, summaries of provisions of the Company’s Organizational Documents or any other instruments or agreements, summaries of legal proceedings, or legal conclusions, is correct in all material respects; all descriptions in the Registration Statement, the General Disclosure Package and the Prospectus of any other Company Documents are accurate in all material respects; and there are no franchises, contracts, indentures, mortgages, deeds of trust, loan or credit agreements, bonds, notes, debentures, evidences of indebtedness, leases or other instruments, agreements or documents required to be described or referred to in the Registration Statement, the Pre-Pricing Prospectus or the Prospectus or to be filed as exhibits to the Registration Statement which have not been so described and filed as required.

(23) Possession of Intellectual Property. The Company and its Material Subsidiaries own and possess or have valid and enforceable licenses to use, all patents, patent rights, patent applications, licenses, copyrights, inventions, know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trade marks, service marks, trade names, service names, software, internet addresses, domain names and other intellectual property (collectively, “Intellectual Property”) that is described in the Registration Statement, the General Disclosure Package or the Prospectus or that is necessary for the conduct of their respective businesses as currently conducted, as proposed to be conducted and as described in the Registration Statement, the General Disclosure Package and the Prospectus. Neither the Company nor any of its subsidiaries has received any notice or is otherwise aware of any material infringement of or conflict with rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid, unenforceable or inadequate to protect the interests of the Company or any of its subsidiaries therein. To the knowledge of the Company, there are no third parties who have or will be able to establish rights to any Intellectual Property of the Company or any of its Material Subsidiaries, except for, and to the extent of, the ownership rights of the owners of the Intellectual Property which the Registration Statement, the General Disclosure Package and the Prospectus disclose is licensed to the Company or any of its subsidiaries. There is no pending or, to the knowledge of the Company, material threatened action, suit, proceeding or claim by others challenging the Company’s or any subsidiary’s rights in or to any such Intellectual Property, or challenging the validity, enforceability or scope of any such Intellectual Property, or asserting that the Company or any subsidiary infringes, misappropriates or otherwise violates, or would, upon the commercialization of any product or service described in the Registration Statement, the General Disclosure Package or the Prospectus, infringe, misappropriate, or otherwise violate, any Intellectual Property of others, and the Company is unaware of any threatened action, suit, proceeding or claim. The Company and each of its Material Subsidiaries have, in all material respects, complied with the terms of each agreement pursuant to which any Intellectual Property has been licensed to the Company or any Material Subsidiary. Any such agreements are in full force and effect, and no event or condition has occurred or exists that gives or, with notice or passage of time or both, would give any person the right to terminate any such agreement such that any such termination would reasonably be expected to have a Material Adverse Effect. There is no patent or patent application that contains material claims that interfere with the issued or pending claims of any such Intellectual Property of the Company or any of its Material Subsidiaries or that challenges the validity, enforceability or scope of any such Intellectual Property.

If at any time when a prospectus is required (or, but for the provisions of Rule 172, would be required) by the applicable law to be delivered in connection with sales of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), any event shall occur or condition shall exist as a result of which it is necessary (or if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus so that the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, will not include any 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 or then prevailing, not misleading or if it is necessary (or if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus in order to comply with the requirements of the 1933 Act, the 1933 Act Regulations, the 1934 Act or the 1934 Act Regulations, the Company will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement (or, if the Representatives or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representatives of its intention to prepare such amendment or supplement) and will promptly prepare and file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to correct such untrue statement or omission or to comply with such requirements, and, in the case of an amendment or post-effective amendment to the Registration Statement, the Company will use its best efforts to have such amendment declared or become effective as soon as practicable, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time an Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary (or, if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend or supplement such Issuer Free Writing Prospectus so that it will not include 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 or then prevailing, not misleading, or if it is necessary (or, if the Representatives or counsel for the Underwriters shall notify the Company that, in their judgment, it is necessary) to amend or supplement such Issuer Free Writing Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly notify the Representatives of such event or condition and of its intention to file such amendment or supplement (or, if the Representatives or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representatives of its intention to prepare such amendment or supplement) and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following the distribution of any Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

(f) Blue Sky and Other Qualifications. The Company will use its best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale, or to obtain an exemption for the Securities to be offered and sold, under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications and exemptions in effect for so long as required for the distribution of the Securities (but in no event for a period of not less than one year from the date of this Agreement); provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation

or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified or exempt, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification or exemption, as the case may be, in effect for so long as required for the distribution of the Securities (but in no event for a period of not less than one year from the date of this Agreement).

(iii) enter into any swap or other agreement, arrangement, hedge or transaction that transfers to another, in whole or in part, directly or indirectly, any of the economic consequences of ownership of any Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for any Ordinary Shares, ADSs or other capital stock,

whether any transaction described in clause (i) or (iii) above is to be settled by delivery of Ordinary Shares, ADSs or other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

Notwithstanding the provisions set forth in the immediately preceding paragraph, the Company may, without the prior written consent of Xxxxx Fargo:

(1) issue Securities to the Underwriters pursuant to this Agreement,

(2) issue Ordinary Shares, options to acquire Ordinary Shares and restricted share units representing Ordinary Shares pursuant to the Company’s incentive compensation program as is in effect on the date of this Agreement,

(3) issue Ordinary Shares upon the vesting of restricted share units or the exercise of options granted under the Company’s incentive compensation program referred to in clause (2) above, as such program is in effect on the date of this Agreement, and

(4) effect dispositions or withholdings of Ordinary Shares solely in connection with the payment of taxes due with respect to the vesting of restricted share units granted under the Company’s incentive compensation program, insofar as such restricted share units are outstanding on the date of this Agreement,

provided, however, that in the case of any issuance described in clause (3) above, each recipient who is a director or executive officer of the Company and who has not executed a written agreement, in substantially the form of Exhibit D-1 to this Agreement, shall execute and deliver to Xxxxx Fargo, Canaccord and UBS, acting on behalf of the Underwriters, not later than one business day prior to the date of such issuance, a written agreement, in substantially the form of Exhibit D-1 to this Agreement and otherwise satisfactory in form and substance to Xxxxx Fargo.

If Xxxxx Fargo, in its sole and absolute discretion, agrees to release or waive the restrictions set forth in a lock-up agreement described in Section 5(i) hereof to permit the transfer of Ordinary Shares, ADSs or other capital stock or other securities by an officer or director of the Company and provides the Company with notice of the impending release or waiver at least three business days before the effective date of the release or waiver, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit D-2 hereto through a major news service at least two business days before the effective date of the release or waiver.

All payments to be made by the Company to the Underwriters under this Agreement shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company is compelled by law to deduct or withhold

such taxes, duties or charges.

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or in any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Underwriters as aforesaid consists of the information described as such in Section 6(b) hereof.

(b) Indemnification by the Underwriters. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein.

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder. Counsel to the indemnified parties shall be selected as follows: counsel to the Underwriters and the other indemnified parties referred to in Section 6(a) above shall be selected by Xxxxx Fargo and counsel to the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Company.

In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Underwriters and the other indemnified parties referred to in Section 6(a) above and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or by the Underwriters on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate of any Underwriter, each officer, director, employee, partner and member of any Underwriter or any such affiliate, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and delivered to the Representatives or counsel to the Underwriters, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person controlling any Underwriter, or by or on behalf of the Company, any officer, director or employee of the Company or any person controlling the Company, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representatives may terminate this Agreement, by notice to the Company at any time on or prior to Closing Date (and, if any Option Securities are to be purchased on an Option Closing Date which occurs after the Closing Date, the Representatives may terminate the obligations of the several Underwriters to purchase such Option Securities, by notice to the Company at any time on or prior to such Option Closing Date) (i) if there has been, at any time on or after the date of this Agreement or since the respective dates as of which information is given in the General Disclosure Package or the Prospectus (in each case exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change or any development that could reasonably expected to result in a material adverse change in the condition (financial or other), results of operations, business, properties, management or prospects of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial

or economic conditions (including, without limitation, as a result of terrorist activities), in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if (A) trading in any securities of the Company has been suspended or materially limited by the Commission, the ASX or the Nasdaq Global Select Market, or (B) trading generally on the NYSE, the Nasdaq Global Select Market, the Nasdaq Global Market, the NYSE Amex, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade or the ASX has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (C) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or in Europe, or (iv) if a banking moratorium has been declared by either federal or New York authorities or (v) if there shall have occurred, at any time on or after the date of this Agreement, any downgrading in the rating of any debt securities of or guaranteed by the Company, by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the 0000 Xxx) or any public announcement that any such organization has placed its rating on the Company or any such debt securities or other securities under surveillance or review or on a so-called “watch list” (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement by any such organization that the Company or any such debt securities or other securities has been placed on negative outlook.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof and except that Sections 1, 6, 7, 8, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21 and 22 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Underwriters.

(a) If one or more of the Underwriters shall fail at the Closing Date or an Option Closing Date to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(1) if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

(2) if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Option Closing Date which occurs after the Closing Date, the obligation of the Underwriters to purchase and of the Company to sell the Option Securities that were to have been purchased and sold on such Option Closing Date, shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10(a) shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of an Option Closing Date which is after the Closing Date, which does not result in a termination of the obligations of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, the Representatives shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing, shall be effective only upon receipt and shall be mailed, delivered by hand or overnight courier, or transmitted by fax (with the receipt of such fax to be confirmed by telephone).

This agreement is being delivered to you in connection with the proposed Underwriting Agreement (the “Underwriting Agreement”) among Sundance Energy Australia Limited, an Australian corporation (the “Company”), Xxxxx Fargo Securities, LLC (“Xxxxx Fargo”), Canaccord Genuity Inc. (“Canaccord”) and UBS Securities LLC (“UBS”), as representatives of a group of underwriters (the “Underwriters”) and the other parties thereto (if any), relating to a proposed underwritten public offering of American Depositary Shares (“ADSs”) each representing ordinary shares, no par value (“Ordinary Shares”) of the Company.

In order to induce you and the other Underwriters to enter into the Underwriting Agreement, and in light of the benefits that the offering of the ADSs will confer upon the undersigned in its capacity as a securityholder and/or an officer or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each Underwriter that, during the period beginning on and including the date of the Underwriting Agreement through and including the date that is the 180th day after the date of the Underwriting Agreement (such period, the “Lock-Up Period”), the undersigned will not, without the prior written consent of Xxxxx Fargo, directly or indirectly:

(i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of any shares of the Company’s Ordinary Shares, ADSs or preferred stock or other capital stock (collectively, “capital stock”) or any securities convertible into or exercisable or exchangeable for Ordinary Shares, ADSs or other capital stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or

(ii) enter into any swap or other agreement, arrangement or transaction that transfers to another, in whole or in part, directly or indirectly, any of the economic consequence of ownership of any Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for any Ordinary Shares, ADSs or other capital stock,

whether any transaction described in clause (i) or (ii) above is to be settled by delivery of Ordinary Shares, ADSs or other capital stock, other securities, in cash or otherwise, or publicly announce any intention to do any of the foregoing.

D-1-1

Notwithstanding the provisions set forth in the immediately preceding paragraph, the undersigned may, without the prior written consent of Xxxxx Fargo, transfer any Ordinary Shares, ADSs or other capital stock or any securities convertible into or exchangeable or exercisable for Ordinary Shares, ADSs or other capital stock:

(1) if the undersigned is a natural person, as a bona fide gift or gifts or by will, by intestate succession or pursuant to a so-called “living trust” or other revocable trust established to provide for the disposition of property on the undersigned’s death, in each case to any member of the immediate family (as defined below) of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned or members of the undersigned’s immediate family, or as a bona fide gift or gifts to a charity or educational institution,

(2) if the undersigned is a partnership or a limited liability company, to a partner or member, as the case may be, of such partnership or limited liability company if, in any such case, such transfer is not for value, and

(3) with regard to Ordinary Shares, to the Company (including by the Company’s withholding of Ordinary Shares) solely for the payment of taxes with respect to the vesting of restricted share units granted under the Company’s incentive compensation program, insofar as such restricted share units are outstanding on the date of the Underwriting Agreement;

provided, however, that in the case of any transfer described in clauses (1), (2) or (3) above, it shall be a condition to the transfer that (A) in the case of transfers pursuant to clauses (1) and (2) above, the transferee executes and delivers to Xxxxx Fargo, Canaccord and UBS, acting on behalf of the Underwriters, not later than one business day prior to such transfer, a written agreement, in substantially the form of this agreement (it being understood that any references to “immediate family” in the agreement executed by such transferee shall expressly refer only to the immediate family of the undersigned and not to the immediate family of the transferee) and otherwise satisfactory in form and substance to Xxxxx Fargo, (B) in the case of a transfer pursuant to clause (1) or (3) above, if the undersigned is required to file a report under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), reporting a reduction in beneficial ownership of Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for Ordinary Shares, ADSs or other capital stock by the undersigned during the Lock-Up Period (as the same may be extended as described above), the undersigned shall include a statement in such report to the effect that (i) in the case of clause (1) above, such transfer is not a transfer for value and that such transfer is being made as a gift, by will or intestate succession or pursuant to a so-called “living trust” or other revocable trust established to provide for the disposition of property on the undersigned’s death, as the case may be and (ii) in the case of clause (3) above, such transfer is reported using transaction code “F”, (C) in the case of a transfer pursuant to clause (2) above, no filing under Section 16(a) of the 1934 Act reporting a reduction in beneficial ownership of Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for Ordinary Shares, ADSs or other capital stock shall be required to be made during the Lock-Up Period (as the same may be extended as described above) and (D) in the case of a transfer pursuant to clause (1) or (2) above, no voluntary filing with the Securities and Exchange Commission or other public report, filing or announcement shall be made in respect of such transfer during this Lock-Up Period (as the same may be extended as described above). For purposes of this paragraph, “immediate family” shall mean any relationship by blood, marriage or adoption not more remote than the first cousin.

Prior to engaging in any transaction or taking any other action that is subject to the restrictions imposed by this agreement at any time during the period from and including the date of this agreement through and including the 34th day following the last day of the Lock-Up Period (prior to giving effect to any extension of the Lock-Up Period as provided above), the undersigned will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the Lock-Up Period (as the same may have been extended as provided above) has expired.

The undersigned further agrees that (i) it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to the registration under the Securities Act of 1933, as amended (the “1933 Act”), of any Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for Ordinary Shares, ADSs or other capital stock, and (ii) the Company may, with respect to any Ordinary Shares, ADSs or other capital stock or any securities convertible into or exercisable or exchangeable for Ordinary Shares,

D-1-2

ADSs or other capital stock owned or held (of record or beneficially) by the undersigned, cause the transfer agent or other registrar to enter stop transfer instructions and implement stop transfer procedures with respect to such securities during the Lock-Up Period.

The undersigned hereby waives any and all notice requirements and rights with respect to the registration of any securities pursuant to any agreement, instrument, understanding or otherwise, including any registration rights agreement or similar agreement, to which the undersigned is a party or under which the undersigned is entitled to any right or benefit and any tag-along rights, co-sale rights or other rights to have any securities (debt or equity) included in the offering contemplated by this agreement or sold in connection with the sale of Securities pursuant to the Underwriting Agreement, provided that such waiver shall apply only to the public offering of Securities pursuant to the Underwriting Agreement and each registration statement filed under the 1933 Act in connection therewith.

If the undersigned is an officer or director of the Company, (1) Xxxxx Fargo agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Ordinary Shares, ADSs or other securities, it will notify the Company of the impending release or waiver, and (2) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Xxxxx Fargo to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (i) the release or waiver is effected solely to permit a transfer not for consideration and (ii) the transferee has agreed in writing to be bound by the same terms described in this agreement to the extent and for the duration that such terms remain in effect at the time of the transfer. The undersigned acknowledges and agrees that Xxxxx Fargo may elect whether or not to grant any such release or waiver in its sole and absolute discretion.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this agreement and that this agreement has been duly authorized (if applicable), executed and delivered by the undersigned and is a valid and binding agreement of the undersigned. This agreement and all authority herein conferred are irrevocable and shall survive the death or incapacity of the undersigned (if a natural person) and shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

If the Underwriting Agreement is not executed by the parties thereto prior to March 15, 2014, this agreement shall automatically terminate and become null and void.

The undersigned acknowledges and agrees that whether or not any public offering of ADSs actually occurs depends on a number of factors, including market conditions.

THE AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
