(ii)    If any Holder disapproves the terms of any underwriting, the Holder may elect to withdraw therefrom by written notice to the Company and the underwriters delivered at least ten (10) days prior to the effective date of the Registration Statement. Any Registrable Securities excluded or withdrawn from the underwritten offering shall be withdrawn from the Registration. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any Registration proceeding begun pursuant to Section 2.1 of this Schedule II if the Registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless such withdrawal is due to an action or inaction of the Company.

3.4    Exempt Transactions. The Company shall have no obligation to Register any Registrable Securities under this Section 3 in connection with a Registration by the Company (i) relating solely to the sale of securities to participants in a Company share plan or equity incentive plan, or (ii) relating to a corporate reorganization or other transaction under Rule 145 of the Securities Act (or comparable provision under the Laws of another jurisdiction, as applicable).

Schedule II

4.     Registration Procedures.

4.1    Registration Procedures and Obligations. Whenever required under this Agreement to effect the Registration of any Registrable Securities held by the Holders, the Company shall, as expeditiously as reasonably possible:

(i)    Prepare and file with the Commission a Registration Statement with respect to those Registrable Securities and, subject to the provisions of Section 2.1(iv) of this Schedule II, use its reasonable best efforts to cause that Registration Statement to become effective, and, upon the request of the Holders holding a majority of the Registrable Securities Registered thereunder, keep the Registration Statement effective until the distribution thereunder has been completed; provided that the Company shall not be required to prepare and file a Registration Statement (or cause such Registration Statement to be declared effective) pursuant to Section 2.1(i) of this Schedule II until after the filing of its Annual Report on Form 20-F for the year ended December 31, 2017 (without limitation to the rights of the Holders pursuant to Section 2.1(iv) of this Schedule II);

(ii)    Prepare and file with the Commission amendments and supplements to that Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to comply with the provisions of applicable securities Laws with respect to the disposition of all securities covered by the Registration Statement;

(iii)    Furnish to the Holders the number of copies of a prospectus, including a preliminary prospectus, required by applicable securities Laws, and any other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them;

(iv)    Use its reasonable best efforts to Register and qualify the securities covered by the Registration Statement under the securities Laws of any jurisdiction, as reasonably requested by the Holders, at the expense of the Holder for any jurisdiction other than the United States, provided, that the Company shall not be required to qualify to do business or file a general consent to service of process in any such jurisdictions;

(v)    If the registration relates to an offering of depositary shares or other securities representing Ordinary Shares deposited pursuant to a deposit agreement or similar facility, cause the depositary under such agreement or facility to accept for deposit under such agreement or facility all Registrable Securities requested by each Holder to be included in such registration in accordance with this Section 4;

(vi)    In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in customary form, with the managing underwriter(s) of the offering;

(vii)    Promptly notify each Holder of Registrable Securities covered by the Registration Statement at any time when a prospectus relating thereto is required to be delivered under applicable securities Laws of (a) the issuance of any stop order by the Commission, or (b) the happening of any event or the existence of any condition as a result of which any prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made, or if in the opinion of counsel for the Company it is necessary to supplement or amend such prospectus to comply with law, and at the request of any such Holder promptly prepare and furnish to such Holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made or such prospectus, as supplemented or amended, shall comply with law;

(viii)    Otherwise comply with all applicable rules and regulations of the Commission to the extent applicable to the applicable registration statement and use its reasonable best efforts to make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act as soon as practicable, beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of such registration statement, which statement shall cover such twelve (12) month period, subject to any proper and necessary extensions;

(ix)    Not, without the prior consent of the holders of at least a majority of voting power of the then outstanding Registrable Securities, make any offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Rule 405 promulgated under the Securities Act;

Schedule II

(x)    Provide a transfer agent and registrar for all Registrable Securities Registered pursuant to the Registration Statement and, where applicable, a number assigned by the Committee on Uniform Securities Identification Procedures for all those Registrable Securities, in each case not later than the effective date of the Registration; and

(xi)    Take all reasonable action necessary to list the Registrable Securities on the primary exchange on which the Company’s securities are then traded.

Notwithstanding anything to the contrary herein, subject to Section 2.1(iv) of this Schedule II, the Company may, by notice to the Holders, suspend the use of the Registration Statement for up to fifteen (15) consecutive Trading Days (but not more than an aggregate of thirty (30) Trading Days (which need not be consecutive Trading Days) during any 12-month period) if the Company determines in good faith that it is appropriate to do so in order to avoid disclosure of any confidential information of the Company where such disclosure would harm the Company, in which case the Company shall not be required to amend or supplement the Registration Statement or any prospectus to disclose such information during such period.

4.2    Information from Holder. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Agreement with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the Registration of such Holder’s Registrable Securities.

4.3    Expenses of Registration. All expenses, other than the underwriting discounts and selling commissions applicable to the sale of Registrable Securities pursuant to this Agreement (which shall be borne by the Holders requesting Registration on a pro rata basis in proportion to their respective numbers of Registrable Securities sold in such Registration), incurred in connection with Registrations, filings or qualifications pursuant to this Agreement, including (without limitation) all Registration, filing and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company and reasonable fees and disbursement of one counsel for all selling Holders, shall be borne by the Company. The Company shall not, however, be required to pay for any expenses of any Registration proceeding begun pursuant to this Agreement if the Registration request is subsequently withdrawn at the request of a majority-in-interest (calculated by reference to the number of Registrable Securities to be registered thereunder) of the Holders requesting such Registration (in which case all participating Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be thereby Registered in the withdrawn Registration).

5.    Registration-Related Indemnification.

5.1    Company Indemnity.

(i)    To the maximum extent permitted by Law, the Company will indemnify and hold harmless each Holder, such Holder’s partners, officers, directors, shareholders and legal counsel, any underwriter (as defined in the Securities Act) and each Person, if any, who controls (as defined in the Securities Act) such Holder or underwriter, against any losses, claims, damages or liabilities (joint or several) to which they may become subject under Laws which are applicable to the Company and relate to action or inaction required of the Company in connection with any Registration, qualification, or compliance, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (each a “Violation”): (a) any untrue statement or alleged untrue statement of a material fact contained in such Registration Statement, on the effective date thereof (including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto), (b) the omission or alleged omission to state in the Registration Statement, on the effective date thereof (including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto), a material fact required to be stated therein or necessary to make the statements therein not misleading, or (c) any violation or alleged violation by the Company of applicable securities Laws, or any rule or regulation promulgated under applicable securities Laws. The Company will reimburse each such Holder, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action.

Schedule II

(ii)    The indemnity agreement contained in this Section 5.1 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld or delayed), nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises solely out of or is solely based upon a Violation that occurs in reliance upon and in conformity with written information furnished in a certificate expressly for use in connection with such Registration by any such Holder, such Holder’s partners, officers, directors, and legal counsel, any underwriter (as defined in the Securities Act) and each Person, if any, who controls (as defined in the Securities Act) such Holder or underwriter. Further, the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Holder or other aforementioned person, or any person controlling such Holder, from whom the person asserting any such losses, claims, damages or liabilities purchased shares in the offering, if a copy of the most current prospectus was not sent or given by or on behalf of such Holder or other aforementioned person to such person, if required by law to have been so delivered, at or prior to the written confirmation of the sale of the shares to such person, and if the prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability.

5.2    Holder Indemnity.

(i)    To the maximum extent permitted by Law, each selling Holder that has included Registrable Securities in a Registration will, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, legal counsel and accountants, any underwriter, any other Holder selling securities in connection with such Registration and each Person, if any, who controls (within the meaning of the Securities Act) the Company, such underwriter or other Holder, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing persons may become subject, under applicable securities Laws, or any rule or regulation promulgated under applicable securities Laws, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder in a certificate expressly for use in connection with such Registration; and each such Holder will reimburse any Person intended to be indemnified pursuant to this Section 5.2, for any legal or other expenses reasonably incurred by such Person in connection with investigating or defending any such loss, claim, damage, liability or action. No Holder’s liability under this Section 5.2 shall exceed the net proceeds (less underwriting discounts and selling commissions) received by such Holder from the offering of securities made in connection with that Registration.

(ii)    The indemnity contained in this Section 5.2 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder (which consent shall not be unreasonably withheld or delayed).

5.3    Notice of Indemnification Claim. Promptly after receipt by an indemnified party under Section 5.1 or Section 5.2 of this Schedule II of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under Section 5.1 or Section 5.2 of this Schedule II, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the indemnifying parties. An indemnified party (together with all other indemnified parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonably incurred fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party, to the extent so prejudiced, of any liability to the indemnified party under this Section 5, but the omission to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 5.

5.4    Contribution. If any indemnification provided for in Section 5.1 or Section 5.2 of this Schedule II is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in lieu of indemnifying such

Schedule II

indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other, in connection with the statements or omissions that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. No Holder’s liability under this Section 5.4, when combined with such Holder’s liability under Section 5.2 of this Schedule II, shall exceed the net proceeds (less underwriting discounts and selling commissions) received by such Holder from the offering of securities made in connection with that Registration.

5.5    Underwriting Agreement. To the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control.

5.6    Survival. The obligations of the Company and Holders under this Section 5 shall survive the completion of any offering of Registrable Securities in a Registration Statement under this Agreement.

6.    Additional Registration-Related Undertakings.

6.1    Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of holders of at least a majority of the then outstanding Registrable Securities held by all Holders on an as-converted basis, enter into any new agreement with any holder or prospective holder of any Equity Securities of the Company that would allow such holder or prospective holder (i) to include such Equity Securities in any Registration filed under Section 2 or Section 3 of this Schedule II, unless under the terms of such agreement such holder or prospective holder may include such Equity Securities in any such Registration only to the extent that the inclusion of such Equity Securities will not reduce the amount of the Registrable Securities of the Holders that are included (or, in a Registration filed under Section 3 hereof, only if such Equity Securities are reduced on a pro rata basis), , or (ii) cause the Company to include such Equity Securities in any Registration filed under Section 2 hereof on a basis pari passu with or more favorable to such holder or prospective holder than is provided to the Holders of Registrable Securities.

6.2    Termination of Registration Rights. The registration rights set forth in Section 2 and Section 3 of this Schedule II above shall terminate on the earlier of (i) the date that is three (3) years after the Effective Date and (ii) with respect to any Holder, the date on which such Holder may sell all of such Holder’s Registrable Securities under Rule 144 of the Securities Act in any ninety (90)-day period.

6.3    Conversion of Convertible Notes. Notwithstanding anything to the contrary provided in this Agreement, the Company shall have no obligation to register Registrable Securities which, if constituting Ordinary Share Equivalents, have not been exercised, converted or exchanged, as applicable, for Ordinary Shares.

6.4    Existing Shareholders Agreement. The Company and the Holders acknowledge and agree that, if any shareholders of the Company elects to participate in a Registration under Section 2 of this Schedule II by exercising their piggyback registration rights under the Existing Shareholders Agreement, such shareholders shall be entitled to participate in such Registration, and shall have the protections against exclusion of their shares in such Registration, in each case in accordance with the Existing Shareholders Agreement.
