The Company has no knowledge of any reason that its chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, without qualification, if and when next due.

(h)Properties and Leases. Except for any Permitted Liens, the Company and each Group Company have good title or usage rights free and clear of any Liens to all the real and personal property that are material to their respective businesses, other than as would be reasonably expected to have a Material Adverse Effect, which are reflected in the Company’s consolidated balance sheet as of December 31, 2016 included in the Company’s Annual Report on Form 20-F for the period then ended, and all real and personal property that are material to their respective businesses acquired since such date, except such real and personal property as has been disposed of in the ordinary course of business and other than as would be reasonably expected to have a Material Adverse Effect. For purposes of this Agreement, “Permitted Liens” means (i) Liens for taxes and other governmental charges and assessments arising in the ordinary course which are not yet due and payable, (ii) Liens of landlords and Liens of carriers, warehousemen, mechanics and materialmen and other like Liens arising in the ordinary course of business for sums not yet due and payable, (iii) any Lien that may arise by operation of law, (iv) Liens under the Company’s existing loan facilities, and (v) other Liens or imperfections on property which are not material in amount or do not materially detract from the value of or materially impair the existing use of the property affected by such Lien or imperfection and other than as would be reasonably expected to have a Material Adverse Effect. All leases of real property and all other leases pursuant to which the Company or such Group Company, as lessee, leases real or personal property, which are material to their respective businesses, are valid and effective in all material respects in accordance with their respective terms and there is not, under any such lease, any existing material default by the Company or such Group Company, in each case other than as would be reasonably expected to have a Material Adverse Effect.

(i)Tax. The Company and each Group Company have timely prepared and filed all tax returns required to have been filed by the Company with the appropriate Government Entities and timely paid all taxes shown thereon or otherwise owed by it, except as would not be reasonably expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and each Group Company in respect of taxes for all fiscal period are adequate in all material respects, and there are no material unpaid assessments against the Company or any Group Company. All taxes and other assessments and levies that the Company or any Group Company is required to withhold or to collect for payment have been duly withheld and collected and paid to the proper Governmental Entity or third party when due. There are no tax Liens or claims pending against the Company, any Group Company or any of their assets or property, other than Permitted Liens. There are no tax audits or investigations pending, which if

8

adversely determined would result in a Material Adverse Effect. The Company does not expect to be classified as a passive foreign investment company, as defined in Section 1297 of United States Internal Revenue Code of 1986, as amended, for the current taxable year or in future taxable years. The Company is, and has been since its inception, treated as a corporation for U.S. federal income tax purposes.

Since December 31, 2016, the business and operations of the Company and the Group Companies have been conducted in the ordinary course of business consistent with past practice, and there has not been any Material Adverse Effect or any change in any method of accounting or accounting policies by the Company or any of the Group Companies.

(k)Related Party Transaction. Other than as disclosed Schedule 1 hereto or in the SEC Documents, there are no material transactions or series of related transactions, agreements, arrangements or understandings, nor are there any currently proposed material transactions, or series of related transactions between the Company or any Group Companies, on the one hand, and the Company, any current or former director or executive officer of the Company or any Group Companies or any person who Beneficially Owns 5% or more of the Ordinary Shares (or any of such person’s immediate family members or Affiliates) (other than Group Companies), on the other hand.

Neither the Company nor any Group Company is subject to any material Governmental Order, nor are there any proceedings with respect to the foregoing pending, or to the knowledge of the Company, threatened.

The Company and each Group Company have all material permits, licenses, authorizations, consents, orders and approvals (collectively, “Permits”) of, and have made all material filings, applications and registrations with, any Governmental Entity that are required in order to carry on their business as presently conducted; and all such Permits are in full force and effect in all material respects and all such filings, applications and registrations are current in all material respects.

When issued and sold against receipt of the consideration therefor as provided in this Agreement, such Ordinary Shares will be validly issued, fully paid and nonassessable, and will not subject the holders thereof to personal liability and will not be subject to preemptive rights of any other shareholder of the Company, nor will such issuance result in the violation or triggering of any price-based antidilution adjustments under any agreement to which the Company or any Group Company is a party.

SECTION 2.2.Representations and Warranties of the Investor. The Investor hereby represents and warrants as of the date hereof and as of the Closing Date to the Company that:

(a)Organization and Authority. The Investor is a Delaware limited liability company, is duly qualified to do business and is in good standing in all jurisdictions where its ownership or leasing of property or the conduct of its business requires it to be so qualified, and has corporate power and authority to own its properties and assets and to carry on its business as it is now being conducted.

(b)Authorization.

(1)The Investor has the corporate power and authority to enter into and deliver each of the Transaction Documents and to carry out its obligations hereunder and thereunder. The execution, delivery and performance of the Transaction Documents by the Investor and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all requisite action on the part of the Investor. This Agreement constitutes the valid and legally binding obligation of the Investor, enforceable against the Investor in accordance with its terms, subject to the Bankruptcy and Equity Exception.

12

(2)Neither the execution, delivery and performance by the Investor of any of the Transaction Documents, nor the consummation of the transactions contemplated hereby and thereby will (i) violate, conflict with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination of, or result in the loss of any benefit or creation of any right on the part of any third party under any material contract to which the Investor is a party, or (ii) violate any ordinance, permit, concession, grant, franchise, law, statute, rule or regulation or any judgment, ruling, order, writ, injunction or decree applicable to the Investor or any of its properties or assets.

(3)No notice to, registration, declaration, notification or filing with, exemption or review by, or authorization, order, consent or approval of, any Governmental Entity, or expiration or termination of any statutory waiting period, is required on the part of the Investor for the execution and delivery of the Transaction Documents by the Investor or the consummation by the Investor of the transactions contemplated thereby.

(c)Purchase for Investment. The Investor acknowledges that the Ordinary Shares have not been registered under the Securities Act or under any state securities laws. The Investor (1) is acquiring the Ordinary Shares pursuant to an exemption from registration under the Securities Act for its own account solely for investment with no present intention or plan to distribute any of the Ordinary Shares to any person nor with a view to or for sale in connection with any distribution thereof, in each case in violation of the Securities Act, (2) will not sell or otherwise dispose of any of the Ordinary Shares, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities laws, and (3) is an “accredited investor” (as that term is defined by Rule 501 of the Securities Act). Without limiting any of the foregoing, neither the Investor nor any of its Affiliates has taken, and the Investor will not, and will cause its Affiliates not to, take any action that would otherwise cause the securities to be purchased hereunder to be subject to the registration requirements of the Securities Act.

(d)Financial Capability. The Investor will have immediately available funds necessary to consummate the Closing, as of the date of the Closing, on the terms and conditions contemplated by this Agreement.

(e)Sophisticated Investor. The Investor is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in shares representing an investment decision like that involved in the purchase of the Purchased Shares, including investments in securities issued by the Company, and has requested, received, reviewed and considered all information it deems relevant in making an informed decision to evaluate the merits and risks of a purchase of the Purchased Shares, and can bear the economic risk and complete loss of its investment in the Purchased Shares.

(f)Existing Ownership. The Investor does not legally or Beneficially Own or control, directly or indirectly, any shares, convertible debt or any securities convertible into or exercisable or exchangeable for, or any rights, warrants or options to acquire, any shares or

13

convertible debt in the Company, or have any agreement, understanding or arrangement to acquire any of the foregoing, except with respect to such Purchased Shares as to be purchased by the Investor pursuant to the transactions contemplated herein.

ADDITIONAL AGREEMENTS

SECTION 4.1.Compliance with Laws.

(a)The Investor acknowledges that it is aware of, and that will advise its representatives of, the restrictions imposed by applicable United States and other applicable jurisdictions’ securities laws with respect to trading in securities while in possession of material non-public information relating to the issuer of such securities and on communication of such information when it is reasonably foreseeable that the recipient of such information is likely to trade such securities in reliance on such information.

SECTION 4.2.Legend.

(a)The Investor agrees that all certificates or other instruments representing the securities subject to this Agreement will bear a legend substantially to the following effect:

16

“THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS. ANY ATTEMPT TO TRANSFER, SELL, OFFER TO SELL, PLEDGE, HYPOTHECATE OR OTHERWISE DISPOSE OF THIS INSTRUMENT IN VIOLATION OF THESE RESTRICTIONS SHALL BE VOID.”

(b)Upon request of the Investor, upon receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Securities Act or applicable state laws, as the case may be, the Company shall promptly cause the legend to be removed from any certificate for any securities. The Investor acknowledges that the Purchased Shares have not been registered under the Securities Act or under any state securities laws and agrees that it will not sell or otherwise dispose of any of the Purchased Shares except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities laws.

SECTION 4.3.Indemnity.

(a)The Company agrees to indemnify and hold harmless the Investor and its Affiliates and each of their respective officers, directors, partners, members, managers, employees and agents, to the fullest extent lawful, from and against any and all actions, suits, claims, proceedings, costs, losses, liabilities, damages, judgments, amounts paid in settlement and other reasonable costs and expenses (including reasonable attorney’s fees and related costs) incurred by such party (collectively, “Losses”) arising out of or resulting from (i) any inaccuracy in or breach of any of the Company’s representations or warranties in SECTION 2.1 of this Agreement, and (ii) the Company’s breach of any of the agreements or covenants made by the Company under this Agreement. In calculating the amount of any Losses hereunder, there shall be subtracted the amount of any insurance proceeds and third-party payments received by the Indemnified Party (as defined below) with respect to such Losses, if any, net of any actual costs or expenses incurred in connection with securing or obtaining such proceeds or payments.

(b)The Investor agrees to indemnify and hold harmless each of the Company and its Affiliates and each of their respective officers, directors, partners, members, managers, employees and agents, to the fullest extent lawful, from and against any and all Losses arising out of or resulting from (i) any inaccuracy in or breach of any of the Investor’s representations or warranties in SECTION 2.2 of this Agreement or (ii) the Investor’s breach of any of the agreements or covenants made by the Investor under this Agreement.

(c)A party entitled to indemnification hereunder (an “Indemnified Party”) shall give written notice to the party indemnifying it (the “Indemnifying Party”) of any claim

17

with respect to which it seeks indemnification promptly after the discovery by such Indemnified Party of any matters giving rise to a claim for indemnification; provided that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this SECTION 4.3 unless and to the extent that the Indemnifying Party shall have been actually prejudiced by the failure of such Indemnified Party to so notify such party. No claim for indemnification may be asserted against any Indemnifying Party for breach of any representation, warranty, covenant or agreement contained herein unless written notice of such claim is received by such Indemnifying Party on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or proceeding is based ceases to survive as set forth in SECTION 6.1. Such notice shall describe in reasonable detail such claim. In case any such action, suit, claim or proceeding is brought against an Indemnified Party, the Indemnified Party shall be entitled to hire, at the cost and expense of the Indemnifying Party, counsel and conduct the defense thereof; provided, however, that the Indemnifying Party shall only be liable for the legal fees and expenses of one law firm for the Indemnified Parties, taken together with regard to any single action or group of related actions, upon agreement by the Indemnified Parties and the Indemnifying Party. If the Indemnifying Party assumes the defense of any claim, the Indemnified Parties shall thereafter deliver to the Indemnifying Party copies of all notices and documents (including court papers) received by the Indemnified Parties relating to the claim, and the Indemnified Parties shall cooperate in the defense or prosecution of such claim. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnifying Party shall not be liable for any settlement of any action, suit, claim or proceeding effected without its written consent; provided, however, that the Indemnifying Party shall not unreasonably withhold, delay or condition its consent. The Indemnifying Party further agrees that it will not, without any Indemnified Party’s prior written consent (which shall not be unreasonably withheld or delayed), settle or compromise any claim or consent to entry of any judgment in respect thereof in any pending or threatened action, suit, claim or proceeding in respect of which indemnification has been sought hereunder unless such settlement or compromise includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, claim or proceeding.

(d)For purposes of the indemnity contained in SECTION 4.3(a)(i) and SECTION 4.3(b)(i), all qualifications and limitations set forth in the parties’ representations and warranties as to “materiality,” “Material Adverse Effect” and words of similar import, shall be disregarded in determining the amount of Losses in respect of any breach of any representation or warranty.

(e)The Company shall not be required to indemnify the Indemnified Parties pursuant to SECTION 4.3(a)(i) (other than the Fundamental Representations), disregarding all qualifications or limitations set forth in its representations and warranties as to “materiality,” “Material Adverse Effect” and words of similar import, (i) with respect to any claim for indemnification if the amount of Losses with respect to such claim are less than $100,000 (any claim involving Losses less than such amount being referred to as a “De Minimis Claim”) and

18

(ii) unless and until the aggregate amount of all Losses incurred with respect to all claims (other than De Minimis Claims) pursuant to SECTION 4.4(a)(i) exceed $1,000,000 (the “Threshold Amount”), in which event the Company shall be responsible for the entire amount of such Losses. The Investor shall not be required to indemnify the Indemnified Parties pursuant to SECTION 4.4(b)(i) (other than the Fundamental Representations), disregarding all qualifications or limitations set forth in the representations and warranties as to “materiality,” “Material Adverse Effect” and words of similar import, (i) with respect to any De Minimis Claim and (ii) unless and until the aggregate amount of all Losses incurred with respect to all claims (other than De Minimis Claims) pursuant to SECTION 4.3(b)(i) exceed the Threshold Amount, in which event the Investor shall be responsible for the entire amount of such Losses. Notwithstanding anything in this SECTION 4.3 or in this Agreement provided otherwise, the aggregate total liability of the Company under SECTION 4.3(a)(i) and SECTION 4.3(a)(ii) shall not exceed one hundred percent (100%) of the Aggregate Purchase Price. Notwithstanding anything in this SECTION 4.3 or in this Agreement provided otherwise, the aggregate total liability of the Investor under SECTION 4.3(b) shall not exceed one hundred percent (100%) of the Aggregate Purchase Price. Absent a showing of fraud by a party, and assuming the Closing has occurred, the indemnification obligation of a party under this SECTION 4.3 shall be the sole remedy of any other party against such party for monetary damages for breach of any representation or warranty or covenant contained in this Agreement. Nothing herein shall limit a party’s right to seek injunctive or other equitable relief in connection with the enforcement of this Agreement.

(f)The obligations of the Indemnifying Party under this SECTION 4.3 shall survive the transfer or redemption of the Ordinary Shares issued pursuant to this Agreement, or the Closing or termination of this Agreement; provided that in the event of any transfer of the Ordinary Shares to a third party that is not an Affiliate of the transferor, the Indemnifying Party shall have no obligations under this SECTION 4.3 to such transferee. The indemnity provided for in this SECTION 4.3 is in addition to, and not in derogation of, any statutory, equitable or common law remedy that any party may have with respect to a breach of the provisions hereof, any other agreement or contract or the transactions contemplated by this Agreement. The Company and the Investor and their Affiliates have and retain all other rights and remedies existing in their favor at law or equity, including without limitation, any actions for specific performance and/or injunctive or other equitable relief (without posting a bond or other security) to enforce or prevent any violations of any provisions of this Agreement. No party to this Agreement (or any of its Affiliates) shall, in any event, be liable or otherwise responsible to any other party (or any of its Affiliates) for any consequential or punitive damages of such other party (or any of its Affiliates) arising out of or relating to this Agreement or the performance or breach hereof. The indemnification rights contained in this SECTION 4.3 are not limited or deemed waived by any investigation or knowledge by the Indemnified Party prior to or after the date hereof.

(g)Any indemnification payments pursuant to this SECTION 4.3 shall be treated as an adjustment to the investment amount for the Purchased Shares for U.S. federal income and applicable state and local tax purposes, unless a different treatment is required by applicable law.

19

SECTION 4.4.Investor Rights. At the Closing, the Company, the Investor and the other parties thereto will each enter into the Investor Rights Agreement, substantially in the form attached as Exhibit D hereto.

SECTION 6.10.Definitions. For purposes hereof, terms, when used herein with initial capital letters, shall have the respective meanings given to them in the respective Sections set forth in the index of defined terms at the beginning of this Agreement.

All article, section, paragraph or clause references not attributed to a particular document shall be references to such parts of this Agreement, and all exhibit, annex and schedule references not attributed to a particular document shall be references to such exhibits, annexes and schedules to this Agreement.

SECTION 6.11.Captions. The article, section, paragraph and clause captions herein are for convenience of reference only, do not constitute part of this Agreement and will not be deemed to limit or otherwise affect any of the provisions hereof.

SECTION 6.12.Severability. If any provision of this Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially the same terms as originally set forth herein, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is essential to the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision.

SECTION 6.13.No Third-Party Beneficiaries. Nothing contained in this Agreement, expressed or implied, is intended to confer or shall confer upon any person other than the express parties hereto, any benefit, right or remedies. The representations and

25

warranties set forth in Article II and the covenants set forth in Articles III and IV have been made solely for the benefit of the parties to this Agreement and (a) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate; and (b) may apply standards of materiality in a way that is different from what may be viewed as material by shareholders of, or other investors in, the Company.

SECTION 6.14.Public Announcements. Without limiting any other provision of this Agreement, the parties hereto, to the extent permitted by applicable law, will consult with each other before issuance, and provide each other the opportunity to review, comment upon and agree on any press release or public statement with respect to this Agreement (which includes the Exhibits and Schedules hereto) and the transactions contemplated hereby and the ongoing business relationship among the parties hereto and thereto. The parties hereto will not issue any such press release or make any such public statement without the prior written consent of the other party, except as may be required by law or any listing agreement with or requirement of the NASDAQ or any other applicable securities exchange, provided that the disclosing party shall, to the extent permitted by applicable law or any listing agreement with or requirement of the NASDAQ or any other applicable securities exchange, inform the other party about the disclosure to be made pursuant to such requirements prior to the disclosure.

SECTION 6.15.Specific Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties shall be entitled to seek specific performance of the terms hereof, this being in addition to any other remedies to which they are entitled at law or equity.

SECTION 6.16.Guarantee

(a)Guarantor guarantees to the Company the due and punctual performance and payment in full of all obligations and liabilities of the Investor under this Agreement, up to any limit on liability pursuant to this Agreement (the “Guaranteed Obligations”). If, for any reason whatsoever, the Investor shall fail to or be unable to duly, punctually and fully pay or perform the Guaranteed Obligations, Guarantor will forthwith pay and cause to be paid, with respect to payment obligations, or perform or cause to be performed, with respect to performance obligations, the Guaranteed Obligations. The guarantee contained in this Section 6.16 is a guarantee of payment and performance and not of collectability.

(b)Guarantor is a legal entity duly organized and validly existing under the Delaware Limited Liability Company Act. Guarantor has the corporate power and authority to enter into and deliver this Agreement and to carry out its obligations hereunder. The execution, delivery and performance of this Agreement by Guarantor has been duly authorized by all requisite action on the part of Guarantor. This Agreement constitutes the valid and legally binding obligation of Guarantor, enforceable against Guarantor in accordance with its terms, subject to the Bankruptcy and Equity Exception. Guarantor’s guaranty of the Guaranteed Obligations is irrevocable and continues only for the duration of the Guaranteed Obligations.
