On the basis of the representations and warranties contained herein, and subject to the terms and conditions set forth herein, the Placement Agent agrees to use its best commercially practicable efforts to solicit and receive offers to purchase the Securities. Notwithstanding anything to the contrary contained in this Agreement, the Placement Agent shall have no obligation to purchase any of the Securities, or any liability to the Company if any prospective purchaser fails to consummate a purchase of any of the Securities.

Any prospectus supplement to the Base Prospectus in preliminary form that describes the Securities and the offering thereof and is used prior to the filing of the Prospectus (as defined below), together with the Base Prospectus, is called a “preliminary prospectus.”

As used herein, the term “Prospectus” shall mean the final prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof (the “Final Prospectus Supplement”), together with the Base Prospectus, in the form first used to confirm sales of the Securities or in the form first made available by the Company to meet requests of Purchasers (as defined below) pursuant to Rule 173 under the 1933 Act. References herein to any preliminary prospectus and the Prospectus shall refer to both the prospectus supplement and the Base Prospectus components of such prospectus. For purposes of this Agreement, all references to the Base Prospectus, Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall (i) be deemed to mean and include any document subsequently filed under the 1934 Act (as defined below) which is incorporated by reference or deemed to be incorporated by reference therein or otherwise deemed by the 1933 Act Regulations to be a part thereof and (ii) be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system or any successor system (“XXXXX”).

(i) Registration Statement and Prospectuses. Each of the Registration Statement and any amendment thereto has become effective under the 1933 Act. No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued under the 1933 Act, no order preventing or suspending the use of any preliminary prospectus or the Prospectus has been issued and no proceedings for any of those purposes have been instituted or are pending or, to the Company’s knowledge, threatened. The Company has complied in all material respects with each request (if any) from the Commission for additional information.

Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations. Each preliminary prospectus, if any, the Prospectus and any amendment or supplement thereto, at the time each was filed with the Commission, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations. Each preliminary prospectus, if any, delivered to the Placement Agent for use in connection with the Offering and the Prospectus was or 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.

At the time the Company’s Annual Report on Form 20-F for the year ended December 31, 2016 (the “Annual Report”) was filed with the Commission, the Company met the then-applicable requirements for use of Form F-3 under the 1933 Act. The Company is a “foreign private issuer” within the meaning of Rule 405 under the 1933 Act.

The documents incorporated or deemed to be incorporated by reference in the Registration Statement, any preliminary prospectus and the Prospectus, when they became effective or at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act.

(ii) Accurate Disclosure. Each preliminary prospectus, if any, and the Prospectus when filed complied in all material respects with the 1933 Act and, if filed by electronic transmission pursuant to XXXXX, was identical (except as may be permitted by Regulation S-T under the 0000 Xxx) to the copy thereof delivered to the Placement Agent for use in connection with the offer and sale of the Securities. Neither the Registration Statement nor any post-effective amendment thereto, at its effective time or at the Closing Time, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, neither (A) the General Disclosure Package nor (B) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will 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. Neither the Prospectus nor any amendment or supplement thereto (including any prospectus wrapper), as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b) or at the Closing Time, included, includes or will include an untrue statement of a material fact or omitted, omits or will 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 representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto), the General Disclosure Package or the Prospectus (or any amendment or supplement thereto, including any prospectus wrapper) made in reliance upon and in conformity with written information furnished to the Company by the Placement Agent expressly for use therein. For purposes of this Agreement, the only information so furnished shall be the information in the last sentence of the eighth paragraph under the heading “Plan of Distribution,” contained in the Prospectus (collectively, the “Placement Agent Information”).

(iii) Issuer Free Writing Prospectuses. No Issuer Free Writing Prospectus conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, and any preliminary or other prospectus deemed to be a part thereof that has not been superseded or modified. The Company has made available a Bona Fide Electronic Road Show in compliance with Rule 433(d)(8)(ii) such that no filing of any “road show” (as defined in Rule 433(h)) is required in connection with the Offering of the Securities.

(iv) Company Not Ineligible Issuer. At the time of filing the Registration Statement and any post-effective amendment thereto, at the earliest time thereafter that the Company made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405, without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an ineligible issuer.

(v) Emerging Growth Company Status. The Company is an “emerging growth company,” as defined in Section 2(a) of the 1933 Act (an “Emerging Growth Company”).

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 therein under the caption “Use of Proceeds”) and compliance by the Company with its obligations hereunder have been duly authorized by all necessary corporate action and 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 or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any properties or assets of the Company pursuant to, the Agreements and Instruments (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances as would not, singly or in the aggregate, reasonably be expected to result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the articles of association of the Company or any law, statute, rule, regulation, judgment, order, writ or decree of any Governmental Entity, except for such violations as would not, singly or in the aggregate, result in a Material Adverse Effect.

(xxvii) Preclinical and Clinical Data and Regulatory Compliance. The preclinical tests and clinical trials that are described in, or the results of which are referred to in, the Registration Statement, the General Disclosure Package or the Prospectus (collectively, “Studies”) were and, if still pending, are being conducted in all material respects in accordance with the protocols, procedures and controls designed and approved for such Studies and with standard medical and scientific research procedures; each description of the results of such Studies is accurate and complete in all material respects and fairly presents the data derived from such Studies; and the Company has no knowledge of any other Studies the results of which are inconsistent with, or otherwise call into question, the results described or referred to in the Registration Statement, the General Disclosure Package or the Prospectus. Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, the Group has not received any written notice of, or correspondence from, any Governmental Authority requiring the termination, suspension or material modification of any Studies. The Company has operated and currently is in compliance with the United States Federal Food, Drug, and Cosmetic Act, all applicable regulations of the FDA, the EMA and other federal, state, local and foreign governmental bodies exercising comparable authority, except where the failure to so operate or be in compliance would not have a Material Adverse Effect.

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 to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Placement Agent, and, in the case of parties indemnified pursuant to Section 6 (b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for the reasonable fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties 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 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 reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) or settlement of any claim in connection with any violation referred to in Section 6(e) effected without its written consent if (i) such settlement is entered into more than 60 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.

(e) The indemnity and contribution agreements contained in Section 6 and Section 7 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of the Placement Agent, its directors or officers or any person controlling the Placement Agent, the Company, its directors or officers or any persons controlling the Company and (ii) any termination of this Agreement. A successor to the Placement Agent, its directors or officers or any person controlling the Placement Agent, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in Section 6 and Section 7.

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 Placement Agent, 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 Placement Agent, on the other hand, in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(e) hereof, 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 Placement Agent, 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, on the one hand, and the total Placement Fee received by the Placement Agent, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Placement Agent, 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 or by the Placement Agent and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 6(e) hereof.

The Company and the Placement Agent agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing 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, the Placement Agent shall not be required to contribute any amount in excess of the Placement Fee received by the Placement Agent in connection with the Securities placed by it.

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 person, if any, who controls the Placement Agent within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the Placement Agent’s Affiliates and selling agents shall have the same rights to contribution as the Placement Agent, 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.

SECTION 8. Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of the Company submitted pursuant hereto, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Placement Agent or its Affiliates or selling agents, any person controlling the Placement Agent, its officers or directors or any person controlling the Company.

SECTION 9. Termination of Agreement.

(a) Termination. The Placement Agent may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, in the reasonable judgment of the Placement Agent, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or prospects of the Company, 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 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, in each case the effect of which is such as to make it, in the reasonable judgment of the Placement Agent, impracticable or inadvisable to proceed with the completion of the Offering or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NASDAQ Global Market, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the NASDAQ Global Market has been suspended or materially 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 (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by either Federal or New York authorities.

(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 provided further that Sections 1, 6, 7, 8, 13, 14 and 15 shall survive such termination and remain in full force and effect. If the issuance to the Purchasers of the Securities, as contemplated by this Agreement and the Subscription Agreements, is not carried out by the Company for any reason permitted under this Agreement, or if such issue is not carried out because the Company shall be unable to comply with any of the terms of this Agreement, the

Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4 and 7 hereof), and the Placement Agent shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 7 hereof) or to one another hereunder.

SECTION 11. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Securities in the Direct Offering, including the determination of the offering price of the Securities and any related Placement Agent fees, is an arm’s-length commercial transaction between the Company, on the one hand, and the Placement Agent, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, the Placement Agent is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its shareholders, creditors, employees or any other party, (c) the Placement Agent has not assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the Offering of the Securities or the process leading thereto (irrespective of whether the Placement Agent has advised or is currently advising the Company on other matters) and the Placement Agent does not have any obligation to the Company with respect to the Offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Placement Agent and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and (e) the Placement Agent has not provided any legal, accounting, regulatory or tax advice with respect to the Offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 12. Parties. This Agreement shall each inure to the benefit of and be binding upon the Placement Agent and the Company and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Placement Agent and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Placement Agent and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.
