Ladies and Gentlemen:

Introductory. Luxfer Holdings PLC, a public limited company incorporated and registered in England and Wales with registered number 3690830 (the “Company”), proposes to sell to the several underwriters named in Schedule A (the “Underwriters”) an aggregate of [·] American Depositary Shares (“ADSs”) (the “Company ADSs”), each representing one-half of an ordinary share, nominal value ₤1 per ordinary share (the “Ordinary Shares”) of the Company; and the shareholders of the Company named in Schedule B (collectively, the “Selling Shareholders”) severally propose to sell to the Underwriters an aggregate of [·] ADSs (the “Selling Shareholder Firm ADSs”). The Company ADSs and the Selling Shareholder Firm ADSs are collectively called the “Firm ADSs.” In addition, the Selling Shareholders have severally granted to the Underwriters an option to purchase up to an additional [·] ADSs (the “Selling Shareholder Optional ADSs”), with each Selling Shareholder selling up to the amount set forth opposite such Selling Shareholder’s name in Schedule B, all as provided in Section 2. The Selling Shareholder Firm ADSs and the Selling Shareholder Optional ADSs are collectively called the “Selling Shareholder ADSs.” The Firm ADSs and, if and to the extent such option is exercised, the Selling Shareholder Optional ADSs are collectively called the “Offered ADSs.” Xxxxxxxxx & Company, Inc. (“Jefferies”) and Credit Suisse Securities (USA) LLC (“Credit Suisse”) have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Offered ADSs.

The ADSs will be evidenced by American depositary receipts (the “ADRs”) to be issued pursuant to a deposit agreement to be entered into on the Closing Date by and among the Company, The Bank of New York Mellon, as depositary (the “Depositary”), and the holders from time to time of the ADRs evidencing ADSs issued thereunder (the “Deposit Agreement”).

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form F-1 (File No. 333-178278), with respect to the Ordinary Shares underlying the Offered ADSs (the “Underlying Shares”), which contains a form of prospectus to be used in connection with the public offering and sale of the Offered ADSs. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, in the form in which it was declared effective by the Commission under the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively, the

“Securities Act”), including any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A under the Securities Act, is called the “Registration Statement.” Any registration statement filed by the Company pursuant to Rule 462(b) under the Securities Act is called the “Rule 462(b) Registration Statement,” and from and after the date and time of filing of the Rule 462(b) Registration Statement the term “Registration Statement” shall include the Rule 462(b) Registration Statement. The preliminary prospectus dated December 2, 2011 describing the Offered ADSs and the offering thereof is called the “Preliminary Prospectus,” and the Preliminary Prospectus and any other preliminary prospectus that describes the Offered ADSs and the offering thereof and is used prior to the filing of the Prospectus (as defined below), is called a “preliminary prospectus.” As used herein, the term “Prospectus” shall mean the final prospectus that describes the Offered ADSs and the offering thereof in the form first used by the Underwriters to confirm sales of the Offered ADSs or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Securities Act. As used herein, “Applicable Time” is : m (New York time) on [·], 2011. As used herein, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act, and “Time of Sale Prospectus” means the preliminary prospectus, as amended or supplemented immediately prior to the Applicable Time, together with the free writing prospectuses, if any, identified in Schedule C hereto, the price to the public to be included on the cover page of the Prospectus, and each “bona fide electronic road show” (as defined in Rule 433(h)(5) under the Securities Act) (a “Road Show”) that has been made without restriction to any person. All references in this Agreement to (i) the Registration Statement, the 462(b) Registration Statement, any Preliminary Prospectus, a preliminary prospectus or the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”) and (ii) the Prospectus shall be deemed to include the “electronic Prospectus” provided for use in connection with the offering of the Offered ADSs as contemplated by Section 3(A)(o) of this Agreement.

The Company and each of the Selling Shareholders hereby confirm their respective agreements with the Underwriters as follows:

Section 1. Representations and Warranties.

A. Representations and Warranties of the Company. The Company hereby represents, warrants and covenants to each Underwriter, as of the date of this Agreement, as of the First Closing Date (as hereinafter defined) and as of each Option Closing Date (as hereafter defined), if any, as follows:

(a) Compliance with Registration Requirements. The Registration Statement and any Rule 462(b) Registration Statement have been declared effective by the Commission under the Securities Act. The Company has complied to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement is in effect and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by the Commission.

Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and, if filed by electronic transmission pursuant to XXXXX (except as may be permitted by Regulation S-T under the Securities Act), was identical to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Offered ADSs. Each of the Registration Statement, any Rule 462(b) Registration Statement and

any post-effective amendment thereto, at the time it became effective and at all subsequent times, complied and will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As of the Applicable Time, the Time of Sale Prospectus, together with each Road Show, if any, (including any preliminary prospectus wrapper) did not, and at the time of each sale of the Offered ADSs and at the First Closing Date (as defined in Section 2), the Time of Sale Prospectus, together with each Road Show, if any, as then amended or supplemented by the Company, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Prospectus (including any Prospectus wrapper), as amended or supplemented, as of its date and at all subsequent times, did not and will not contain 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, not misleading. The representations and warranties set forth in the three immediately preceding sentences do not apply to statements in or omissions from the Registration Statement, any Rule 462(b) Registration Statement, or any post-effective amendment thereto, or the Prospectus or the Time of Sale Prospectus, or any amendments or supplements thereto or any Road Show, made in reliance upon and in conformity with information relating to any Underwriter furnished to the Company in writing by the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by the Representatives to the Company consists of the information described in Section 9(c) below. There are no contracts or other documents required to be described in the Time of Sale Prospectus or the Prospectus or to be filed as exhibits to the Registration Statement which have not been described or filed as required.

The Company is not an “ineligible issuer” in connection with the offering of the Offered ADSs pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used or referred to by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act including timely filing with the Commission or retention where required and legending, and each such free writing prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered ADSs did not, does not and will not include any information that conflicted with, conflicts with or will conflict with the information contained in the Registration Statement, the Prospectus or any preliminary prospectus. Except for the free writing prospectuses, if any, identified in Schedule C hereto, and electronic road shows, if any, furnished to you before first use, the Company has not prepared, used or referred to, and will not, without your prior consent, which consent shall not be unreasonably withheld, prepare, use or refer to, any free writing prospectus.

(b) Offering Materials Furnished to Underwriters. The Company has delivered to the Representatives two complete copies of the Registration Statement, each amendment thereto and any Rule 462(b) Registration Statement and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement, each amendment thereto and any Rule 462(b) Registration Statement (without exhibits) and preliminary prospectuses, the Time of Sale Prospectus, the Prospectus, as amended or supplemented, and any free writing prospectus reviewed and consented to by the Representatives, in such quantities and at such places as the Representatives have reasonably requested for each of the Underwriters.

(c) Distribution of Offering Material By the Company. The Company has not distributed and will not distribute, prior to the later of (i) the expiration or termination of the option granted to the several Underwriters in Section 2, (ii) the completion of the Underwriters’ distribution of the Offered ADSs and (iii) the expiration of 25 days after the date of the Prospectus, any offering material in connection with the offering and sale of the Offered ADSs other than a preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus reviewed and consented to by the Representatives, or the Registration Statement.

(d) The Underwriting Agreement. The execution and delivery of, and the performance by the Company of its obligations under, this Agreement has been duly and validly authorized by all necessary corporate action on the part of the Company, and this Agreement has been duly executed and delivered by the Company.

(e) The Deposit Agreement. The Deposit Agreement has been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery by the Depositary, constitutes a valid and legally binding obligation of the Company, enforceable in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. Upon due issuance by the Depositary of the ADRs evidencing the Offered ADSs against the deposit of the Underlying Shares in respect thereof in accordance with the provisions of the Deposit Agreement, such ADRs will be duly and validly issued, fully paid and nonassessable, freely transferable to and for the account of the Underwriters, and the persons in whose name the ADRs are registered will be entitled to the rights specified therein and in the Deposit Agreement. Except as disclosed in the Registration Statement and any Applicable Prospectus, the sale of the Offered ADSs by the Company and the deposit of the Ordinary Shares with the Depositary and the issuance of the ADRs evidencing the Offered ADSs as contemplated by this Agreement and the Deposit Agreement will neither (i) cause any holder of any shares of capital stock, securities convertible into or exchangeable or exercisable for capital stock or options, warrants or other rights to purchase capital stock or any other securities of the Company to have any right to acquire any shares of preferred stock of the Company nor (ii) trigger any anti-dilution, pre-emption, rights of first refusal or other similar rights of any such holder with respect to such shares, securities, options, warrants or rights.

(f) Authorization of the Company Underlying Shares and Ordinary Shares Underlying Options. The Ordinary Shares underlying the Company ADSs (the “Company Underlying Shares”) have been duly authorized for issuance and sale pursuant to this Agreement and, when issued and delivered by the Company to the Depositary or the custodian for the Depositary, will be validly issued, fully paid and nonassessable; there are no restrictions on subsequent transfers of the Ordinary Shares under the laws of England and Wales or the United States or the articles of association of the Company, except as described in the Registration Statement or any Applicable Prospectus; and the issuance of the Company Underlying Shares is not subject to any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company, except as have been duly waived. Upon the sale and delivery to the Underwriters of the Offered ADSs, and payment therefor pursuant to this Agreement, the Underwriters will acquire such Offered ADSs free and clear of any security interest, mortgage, pledge, lien, encumbrance or adverse claim.

(g) No Applicable Registration or Other Similar Rights.

(h) No Material Adverse Change. Except as otherwise disclosed in the Time of Sale Prospectus, subsequent to the respective dates as of which information is given in the Time of Sale Prospectus: (i) 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 otherwise, or in the earnings, business or results of operations, whether or not arising from transactions in the ordinary course of business, of the Company and its subsidiaries, considered as one entity (any such change is called a “Material Adverse Change”); (ii) the Company and its subsidiaries, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business nor entered into any material transaction or agreement not in the ordinary course of business; and (iii) there has been no dividend or distribution of any kind declared, paid or made by the Company or, except for dividends paid to the Company or other subsidiaries, any of its subsidiaries on any class of capital stock or repurchase or redemption by the Company or any of its subsidiaries of any class of capital stock.

Ernst & Young LLP, who have expressed their opinion with respect to the financial statements (which term as used in this Agreement includes the related notes thereto) filed with the Commission as a part of the Registration Statement and included in the Preliminary Prospectus, the Prospectus and Time of Sale Prospectus (each, an “Applicable Prospectus” and collectively, the “Applicable Prospectuses”), are (i) independent public or certified public accountants as required by the Securities Act and the Exchange Act, (ii) to the knowledge of the Company, in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X and (iii) a registered public accounting firm as defined by the Public Company Accounting Oversight Board (the “PCAOB”) whose registration, to the knowledge of the Company, has not been suspended or revoked and who have not requested such registration to be withdrawn.

(j) Preparation of the Financial Statements. The financial statements filed with the Commission as a part of the Registration Statement and included in the Preliminary Prospectus, the Time of Sale Prospectus and the Prospectus present fairly the consolidated financial position of the Company and its subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. Such financial statements have been prepared in conformity with the International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”) applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. No other financial statements or supporting schedules are required to be included in the Registration Statement or any Applicable Prospectus. The financial data set forth in each Applicable Prospectus under the captions “Summary—Summary Consolidated Financial Data,” “Selected Consolidated Financial Data” and “Capitalization” fairly present the information set forth therein on a basis consistent with that of the audited financial statements contained in the Registration Statement and each Applicable Prospectus. To the knowledge of the Company, no person who has been suspended or barred from being associated with a registered public accounting firm, or who has failed to comply with any sanction pursuant to Rule 5300 promulgated by the PCAOB, has participated in or otherwise aided the preparation of, or audited, the financial statements, supporting schedules or other financial data filed with the Commission as a part of the Registration Statement and included in any Applicable Prospectus.

(k) Company’s Accounting System, Internal Control Over Financial Reporting and Disclosure Controls and Procedures. The Company and each of its subsidiaries make and keep accurate books and records and maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s

general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with IFRS and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. There has not been and there is no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and since December 31, 2010 there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company is not aware of (i) any significant deficiencies or material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting. The Company and its subsidiaries maintain disclosure controls and procedures that have been designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities; and such disclosure controls and procedures are effective in all material respects to perform the functions for which they were established.

(l) Incorporation and Good Standing of the Company and its Subsidiaries. The Company has been duly incorporated and is validly existing as a public limited company in good standing under the laws of England and Wales, with full power and authority (corporate or other) to own or lease its properties and conduct its business as described in the Registration Statement and each Applicable Prospectus and to enter into and perform its obligations under this Agreement and the Deposit Agreement. Each of the Company’s subsidiaries has been duly incorporated or organized, as the case may be, and is validly existing as a corporation, partnership or limited liability company, as applicable, in good standing under the laws of the jurisdiction of its incorporation or organization and has the power and authority (corporate or other) to own, lease and operate its properties and to conduct its business as described in each Applicable Prospectus, except to the extent that the failure to be in good standing would not, individually or in the aggregate, result in a Material Adverse Change. Each of the Company and each subsidiary is duly qualified as a foreign corporation, partnership or limited liability company, as applicable, to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except to the extent that the failure to be so qualified would not, individually or in the aggregate, result in a Material Adverse Change. All of the issued and outstanding share capital, capital stock or other equity or ownership interests of each of the Company’s subsidiaries has been duly authorized and validly issued, are fully paid and nonassessable and, except as set forth in the Time of Sale Prospectus, are owned by the Company, directly or through its subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or adverse claim. The Company does not own or control, directly or indirectly, any corporation, association or other entity other than (i) the subsidiaries listed in Exhibit 21 to the Registration Statement and (ii) such other entities omitted from Exhibit 21 which, when such omitted entities are considered in the aggregate as a single subsidiary, would not constitute a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X.

(m) Capitalization and Other Share Capital Matters. The authorized and issued share capital of the Company is as set forth in each Applicable Prospectus under the caption “Capitalization” (other than for subsequent issuances, if any, pursuant to employee benefit plans described in the Time of Sale Prospectus or upon the exercise of outstanding options described in

each Applicable Prospectus). All of the Offered ADSs and the Underlying Shares conform in all material respects to the description thereof contained in the Time of Sale Prospectus. All of the issued and outstanding Ordinary Shares (including the Ordinary Shares owned by Selling Shareholders and the Ordinary Shares to be purchased by Selling Shareholders pursuant to an exercise by any such Selling Shareholder of an option pursuant to an Option Exercise Notice) have been duly and validly authorized and issued, are fully paid and not subject to further assessment. None of the issued Ordinary Shares were issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. There are no authorized or outstanding options, warrants, preemptive rights, rights of first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any share capital or capital stock of the Company or any of its subsidiaries other than those accurately described in each Applicable Prospectus. The description of the Company’s share option, share bonus and other share plans or arrangements, and the options or other rights granted thereunder, set forth in each Applicable Prospectus accurately and fairly presents the information required to be shown with respect to such plans, arrangements, options and rights.

(n) Stock Exchange Listing. The Offered ADSs have been approved for listing on the New York Stock Exchange, subject only to official notice of issuance.

(o) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is in violation of its memorandum or articles of association, charter or by-laws, partnership agreement or operating agreement or similar organizational document, as applicable, or is in default (or, with the giving of notice or lapse of time, would be in default) (“Default”) under any indenture, mortgage, loan or credit agreement, note, contract, franchise, lease or other instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound (including, without limitation, any credit agreement, indenture, pledge agreement, security agreement or other instrument or agreement evidencing, guaranteeing, securing or relating to indebtedness of the Company or any of its subsidiaries ), or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”), except for such Defaults as would not, individually or in the aggregate, result in a Material Adverse Change. The Company’s execution, delivery and performance of this Agreement and the Deposit Agreement, consummation of the transactions contemplated hereby and thereby and by each Applicable Prospectus and the issuance and sale of the Company ADSs and the allotment and issue of the Underlying Shares (i) have been duly authorized by all necessary corporate action and will not result in any violation of the provisions of the memorandum or articles of association, charter or by-laws, partnership agreement or operating agreement or other similar organizational document of the Company or any subsidiary, as applicable, (ii) will not conflict with or constitute a breach of, or Default or a Debt Repayment Triggering Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any of its subsidiaries pursuant to, or require the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any law, administrative regulation or administrative or court decree applicable to the Company or any subsidiary, except, in the case of clauses (ii) and (iii) above, as would not, individually or in the aggregate, result in a Material Adverse Change. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required for the Company’s execution, delivery and performance of this Agreement and the Deposit Agreement and consummation of the transactions contemplated hereby and thereby and by each Applicable Prospectus, except such as have been obtained or made by the Company and are in full force and effect under the Securities Act, applicable state securities or blue sky laws and from the Financial

Industry Regulatory Authority, Inc. (“FINRA”). As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Company or any of its subsidiaries.

(p) No Material Actions or Proceedings. Except as disclosed in the Registration Statement and any Applicable Prospectus, there are no legal or governmental actions, suits or proceedings pending or, to the best of the Company’s knowledge, threatened (i) against or affecting the Company or any of its subsidiaries, (ii) which have as the subject thereof any officer or director of, or property owned or leased by, the Company or any of its subsidiaries or (iii) relating to environmental or discrimination matters, which, if determined adversely to the Company would reasonably be expected to result in a Material Adverse Change or adversely affect the consummation of the transactions contemplated by this Agreement. No material labor dispute with the employees of the Company or any of its subsidiaries, or with the employees of any principal supplier, manufacturer, customer or contractor of the Company, exists or, to the best of the Company’s knowledge, is threatened or imminent.

(q) Intellectual Property Rights. The Company and its subsidiaries own or have the right to use the trademarks, trade names, patent rights, copyrights, domain names, trade secrets and other similar rights (collectively, “Intellectual Property Rights”) used in their businesses as now conducted, except as would not individually or in the aggregate result in a Material Adverse Change; and the expected expiration of any of such Intellectual Property Rights would not result in a Material Adverse Change. Neither the Company nor any of its subsidiaries has received, or has any reason to believe that it will receive, any written notice of infringement, misappropriation or conflict with asserted Intellectual Property Rights of others which would result in a Material Adverse Change. To the Company’s knowledge, no third party has infringed, misappropriated or otherwise violated any Intellectual Property Rights of the Company or any of its subsidiaries material to the conduct of their business. The Company is not a party to or bound by any options, licenses or agreements with respect to its Intellectual Property Rights or the Intellectual Property Rights of any other person or entity that are required to be set forth in the Prospectus and are not described therein. None of the technology employed by the Company or any of its subsidiaries has been obtained or is being used by the Company or any of its subsidiaries in violation of any contractual obligation binding on the Company or any of its subsidiaries or any of its or its subsidiaries’ officers, directors or employees or otherwise in violation of the rights of any persons which would result in a Material Adverse Change.

(r) All Necessary Permits, etc The Company and each subsidiary possess such valid and current certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses, and neither the Company nor any subsidiary has received, or has any reason to believe that it will receive, any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit, which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could result in a Material Adverse Change.

(s) Title to Properties. The Company and each of its subsidiaries has good and marketable title to all of the real and personal property and other assets reflected as owned in the financial statements referred to in Section 1(A)(j) above (or elsewhere in each Applicable Prospectus), in each case free and clear of any security interests, mortgages, liens, encumbrances, equities, adverse claims and other defects, except for those described in the Registration Statement or any Applicable Prospectus or which do not materially and adversely affect the value

of such property or assets and do not materially interfere with the use made or proposed to be made of such property or assets by the Company or such subsidiary. The real property, improvements, equipment and personal property held under lease by the Company or any subsidiary are held under valid and enforceable leases, with such exceptions as are not material and do not materially interfere with the use made or proposed to be made of such real property, improvements, equipment or personal property by the Company or such subsidiary.

(t) Tax Law Compliance. The Company and its subsidiaries have filed all necessary national, federal, state and foreign tax returns and have paid all taxes (including social security contributions and taxes required to be withheld from payments) required to be paid by any of them and, if due and payable, any related or similar assessment, fine or penalty levied against any of them, except for any such taxes, assessments, fines or penalties currently being contested in good faith and except where the failure to so file or pay, as applicable, would not, individually or in the aggregate, result in a Material Adverse Change. All material tax liabilities of the Company and its subsidiaries (including any liabilities currently being contested in good faith) have been adequately provided for in the financial statements of the Company or its subsidiaries. To the knowledge of the Company, there are no actual or proposed additional material tax assessments against the Company or any of its subsidiaries, except as otherwise described in the Registration Statement or each Applicable Prospectus.

(u) Company Not an “Investment Company”. The Company has been advised of the rules and requirements under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Company is not, and will not be, either after receipt of payment for the Company ADSs or after the application of the proceeds therefrom as described under “Use of Proceeds” in each Applicable Prospectus, an “investment company” within the meaning of Investment Company Act and will conduct its business in a manner so that it will not become subject to the Investment Company Act.

(v) Insurance. Each of the Company and its subsidiaries are insured by recognized, financially sound and reputable institutions with policies in such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its subsidiaries against theft, damage, destruction, acts of vandalism and earthquakes and policies covering the Company and its subsidiaries for product liability claims. The Company has no reason to believe that it or any of its subsidiaries will not be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Change. Neither the Company nor any subsidiary has been denied any insurance coverage material to the Company and its subsidiaries, taken as a whole, which it has sought or for which it has applied.

(w) No Price Stabilization or Manipulation; Compliance with Regulation M. The Company has not taken, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Offered ADSs or Ordinary Shares or any other “reference security” (as defined in Rule 100 of Regulation M under the Exchange Act (“Regulation M”)) whether to facilitate the sale or resale of the Offered ADSs, the Ordinary Shares or otherwise, and has taken no action which would directly or indirectly violate Regulation M.

Except as described in each Applicable Prospectus and except as would not, individually or in the aggregate, result in a Material Adverse Change, (i) neither the Company nor any of its subsidiaries is in violation of any applicable federal, state, local or foreign statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (ii) the Company and its subsidiaries have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in compliance with their requirements, and (iii) there are no pending or threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or any of its subsidiaries.

(cc) Periodic Review of Costs of Environmental Compliance. In the ordinary course of its business, the Company conducts and has in the past conducted periodic reviews of the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates and has identified and evaluated associated costs and liabilities (including, without limitation, any capital or operating

expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such reviews and the amount of the reserves it has established, the Company has reasonably concluded that such associated costs and liabilities would not, individually or in the aggregate, result in a Material Adverse Change.

(dd) ERISA Compliance. Any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the Company, its subsidiaries or their “ERISA Affiliates” (as defined below) is in compliance with all material provisions of ERISA, except as would not, individually or in the aggregate, result in a Material Adverse Change. “ERISA Affiliate” means, with respect to the Company or any of its subsidiaries, any member of any group or organizations described in sections 414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company or such subsidiary is a member. No “reportable event” (as defined under ERISA) has occurred within the preceding five (5) years or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates except as would not, individually or in the aggregate, result in a Material Adverse Change. No “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA) except as disclosed in the Registration Statement and any Applicable Prospectus or except as would not, individually or in the aggregate, result in a Material Adverse Change. Neither the Company, its subsidiaries nor any of their ERISA Affiliates has incurred within the preceding three (3) years or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code, in each case (i) and (ii) except as would not, individually or in the aggregate, result in a Material Adverse Change. Each “employee benefit plan” established or maintained by the Company, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification, except where failure to so qualify would not result in a Material Adverse Change.

(ee) Brokers. Except for the underwriting discounts and commissions payable to the Underwriters as described in the Time of Sale Prospectus and the Prospectus, there is no broker, finder or other party that is entitled to receive from the Company any brokerage or finder’s fee or other fee or commission as a result of any transactions contemplated by this Agreement.

(ff) Compliance with Laws. Except as disclosed in the Registration Statement and any Applicable Prospectus, the Company has not been advised, and has no reason to believe, that it and each of its subsidiaries are not conducting business in compliance with all applicable laws, rules and regulations of the jurisdictions in which it is conducting business, except where failure to be so in compliance would not result in a Material Adverse Change.

become due under any loans or advances to such subsidiary from the Company or from transferring any property or assets to the Company or to any other subsidiary or subject to any other prohibition or restriction which could restrict the ability of the Company’s subsidiaries to pass profits up to the Company and be treated by the Company as profits available for distribution in accordance with the meaning of Part 23 of the Companies Xxx 0000 of England and Wales. Dividend payments or distributions in respect of any shares of capital stock of the Company (including the Ordinary Shares, Offered ADSs and the ADRs) and payments on the shares of capital stock (including the Ordinary Shares, Offered ADSs and the ADRs) may be paid to the holders thereof free and clear of any withholding or deduction for or on account of United Kingdom tax.

To the knowledge of the Company, no person who performs or who has performed services for the Company or any of its subsidiaries has bribed any other person (within the meaning of section 7(3) of the Bribery Act) intending to obtain or retain business or an advantage in the conduct of business for the Company or any of its subsidiaries. The Company and its subsidiaries have adequate procedures in place to prevent any persons who perform services for or on behalf of the Company or any of its subsidiaries from bribing another person (within the meaning given in section 7(3) of the Bribery Act) intending to obtain or retain business or an advantage in the conduct of business for the Company or any of its subsidiaries.

If the Time of Sale Prospectus is being used to solicit offers to buy the Offered ADSs at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus so that the Time of Sale Prospectus does 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 when delivered to a prospective purchaser, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement, or if it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, including the Securities Act, the Company shall (subject to Sections 3(b) and 3(c)) forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented 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 when delivered to a prospective purchaser, not misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law including the Securities Act.

(f) Securities Act Compliance. After the date of this Agreement, the Company shall promptly advise the Representatives in writing (i) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (ii) of the time and date of any filing of any post-effective amendment to the Registration Statement, any Rule 462(b) Registration Statement or any amendment or supplement to the Preliminary Prospectus, the Time of Sale Prospectus, any free writing prospectus or the Prospectus, (iii) of the time and date that any post-effective amendment to the Registration Statement or any Rule 462(b) Registration Statement becomes effective and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto, any Rule 462(b) Registration Statement or any amendment or supplement to the Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus or of any order preventing

or suspending the use of any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the ADSs or the Ordinary Shares from any securities exchange upon which they are listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. If the Commission shall enter any such stop order at any time, the Company will use its reasonable best efforts to obtain the lifting of such order at the earliest possible moment. Additionally, the Company agrees that it shall comply with the provisions of Rule 424(b), Rule 433 and Rule 430A, as applicable, under the Securities Act and will use its reasonable efforts to confirm that any filings made by the Company under such Rule 424(b) or Rule 433 were received in a timely manner by the Commission.

Neither the Representatives’ consent to, or delivery of, any such amendment or supplement shall constitute a waiver of any of the Company’s obligations under Sections 3(b) or (c).

(h) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Offered ADSs for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial securities laws (or other foreign laws as the Representatives shall reasonably require) of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered ADSs. The Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Offered ADSs for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible moment.

(m) Deposit of Ordinary Shares. Prior to or on the Closing Date, the Company agrees to deposit or cause to be deposited Ordinary Shares with the Depositary in accordance with the provisions of the Deposit Agreement and will otherwise comply with the Deposit Agreement so that ADRs evidencing Offered ADSs will be executed (and if applicable countersigned) and issued by the Depositary against receipt of such Ordinary Shares and delivered to the Underwriters at such Closing Date.

The Company agrees to indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act, other federal or state statutory law or regulation, or the laws or regulations of foreign jurisdictions where Offered ADSs have been offered or sold or at common law or otherwise (including in settlement of any litigation, if such settlement is effected in accordance with Section 9(e)), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any “issuer free writing prospectus” as defined Rule 433 of the Securities Act (“Issuer Free Writing Prospectus”) or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and to reimburse each Underwriter and each such director, officer, employee and controlling person for any and all documented expenses (including the fees and disbursements of counsel chosen by Jefferies and Credit Suisse) as such expenses are reasonably incurred by such Underwriter or such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any such free writing prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by the Representatives to the Company consists of the information described in subsection (c) below. The indemnity agreement set forth in this Section 9(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Underwriters by the Selling Shareholders. Each Selling Shareholder agrees, severally and not jointly, to indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act, other federal or state statutory law or regulation, or the laws or regulations of foreign jurisdictions where Offered ADSs have been offered or sold or at common law or otherwise (including in settlement of any litigation, if such settlement is effected in accordance with Section 9(e)), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Selling Shareholder Information with respect to such Selling Shareholder contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements

therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Selling Shareholder Information with respect to such Selling Shareholder contained in any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, such preliminary prospectus, the Time of Sale Prospectus, such Road Show, such free writing prospectus or the Prospectus (or such amendment or supplement thereto), in reliance upon and in conformity with the Selling Shareholder Information with respect to such Selling Shareholder; and to reimburse each Underwriter and each such director, officer, employee and controlling person for any and all documented expenses (including the fees and disbursements of counsel chosen by Jefferies and Credit Suisse) as such expenses are reasonably incurred by such Underwriter, or such director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply (i) to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any such free writing prospectus or the Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information furnished by the Representatives to the Company consists of the information described in subsection (c) below, or (ii) for any amount arising under this subsection (b) in excess of the proceeds from the public offering contemplated hereby received by such Selling Shareholder after deducting any underwriting discounts and commissions received by the Underwriters (the “Net Proceeds”). The indemnity agreement set forth in this Section 9(b) shall be in addition to any liabilities that each Selling Shareholder may otherwise have.

(c) Indemnification of the Company, its Directors and Officers and the Selling Shareholders. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement, the Selling Shareholders and each person, if any, who controls the Company or any Selling Shareholder within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, or any such director, officer, Selling Shareholder or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any Issuer Free Writing Prospectus or the Prospectus (or such amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, such preliminary prospectus, the Time of Sale Prospectus, such Road Show, such Issuer Free Writing Prospectus, the Prospectus (or such amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company and the Selling Shareholders by the Representatives expressly for use

therein; and to reimburse the Company, or any such director, officer, Selling Shareholder or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer, Selling Shareholder or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and each of the Selling Shareholders, hereby acknowledges that the only information that the Representatives and the Underwriters have furnished to the Company and the Selling Shareholders expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any Road Show, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) are the table in the first paragraph set forth under the caption “Underwriting” and the statements set forth in (i) the last sentence in the fifth paragraph under the caption “Underwriting,” (ii) the first, second and third sentences in the first paragraph under the caption “Underwriting—Commission and Expenses” and (iii) the first paragraph, the second and third sentence of the second paragraph and the second and third sentence of the third paragraph under the caption “Underwriting—Stabilization.” The indemnity agreement set forth in this Section 9(c) shall be in addition to any liabilities that each Underwriter may otherwise have.

(d) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof, but the omission so to notify the indemnifying party will not relieve the indemnifying party from any liability which it may have to any indemnified party for contribution or otherwise than under the indemnity agreement contained in this Section 9 or to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 9 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (together with local counsel), representing the indemnified parties who are parties to such action), which counsel (together with any local counsel) for the indemnified parties shall be selected by Jefferies and Credit Suisse (in the case of counsel for the indemnified parties referred to in Sections 9(a) and 9(b) above) or by the Company (in the case of counsel for the indemnified parties referred to in Section 9(c) above)) (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the

action or (iii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party and shall be paid as they are incurred.

(e) Settlements. The indemnifying party under this Section 9 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, 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 Section 9(d) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding 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 the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding.

Section 10. Contribution. If the indemnification provided for in Section 9 is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, from the offering of the Offered ADSs pursuant to this Agreement or (ii) if the allocation provided by clause (i) above 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 and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Offered ADSs pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Offered ADSs pursuant to this Agreement (before deducting expenses) received by the Company and the Selling Shareholders, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the aggregate initial public offering price of the Offered ADSs as set forth on such cover. The relative fault of the Company and the Selling Shareholders, 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 or the Selling Shareholders, on the one hand, or 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 amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 9(d), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 9(d) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 10; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 9(d) for purposes of indemnification.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 10 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 in this Section 10.

Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by such Underwriter in connection with the Offered ADSs underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 10 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their respective names on Schedule A. For purposes of this Section 10, each officer and employee of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange 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 with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company.

Section 11. Default of One or More of the Several Underwriters. If, on the First Closing Date or the applicable Option Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Offered ADSs that it or they have agreed to purchase hereunder on such date, and the aggregate number of Offered ADSs which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Offered ADSs to be purchased on such date, the Representatives may make arrangements satisfactory to the Company for the purchase of such Offered ADSs by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the other Underwriters shall be obligated, severally and not jointly, in the proportions that the number of Firm ADSs set forth opposite their respective names on Schedule A bears to the aggregate number of Firm ADSs set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Offered ADSs which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the First Closing Date or the applicable Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Offered ADSs and the aggregate number of Offered ADSs with respect to which such default occurs exceeds 10% of the aggregate number of Offered ADSs to be purchased on such date, and arrangements

satisfactory to the Representatives and the Company for the purchase of such Offered ADSs are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 7, Section 9 and Section 10 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company shall have the right to postpone the First Closing Date or the applicable Option Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 11. Any action taken under this Section 11 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

Section 12. Termination of this Agreement. Prior to the purchase of the Firm ADSs by the Underwriters on the First Closing Date this Agreement may be terminated by the Representatives by notice given to the Company and the Selling Shareholders if at any time (i) trading or quotation in any of the Company’s securities shall have been suspended or limited by the Commission or by the NYSE, or trading in securities generally on either the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or FINRA; (ii) a general banking moratorium shall have been declared by federal or New York authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable to market the Offered ADSs in the manner and on the terms described in the Time of Sale Prospectus or the Prospectus or to enforce contracts for the sale of securities; (iv) in the judgment of the Representatives there shall have occurred any Material Adverse Change; or (v) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character as in the judgment of the Representatives may interfere materially with the conduct of the business and operations of the Company. Any termination pursuant to this Section 12 shall be without liability on the part of (a) the Company or the Selling Shareholders to any Underwriter, except that the Company and the Selling Shareholders shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 4 and 7 hereof, (b) any Underwriter to the Company or the Selling Shareholders, or (c) of any party hereto to any other party except that the provisions of Section 9 and Section 10 shall at all times be effective and shall survive such termination.

Section 13. No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (a) the purchase and sale of the Offered ADSs pursuant to this Agreement, including the determination of the public offering price of the Offered ADSs and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction each Underwriter 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) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the

Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters 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 Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

Section 14. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Company, of its officers, of the Selling Shareholders and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of its or their partners, officers or directors or any controlling person, or the Selling Shareholders, as the case may be, and, anything herein to the contrary notwithstanding, will survive delivery of and payment for the Offered ADSs sold hereunder and any termination of this Agreement.

to the benefit of the employees, officers and directors and controlling persons referred to in Section 9 and Section 10, and in each case their respective successors, and personal representatives, and no other person will have any right or obligation hereunder. The term “successors” shall not include any purchaser of the Offered ADSs as such from any of the Underwriters merely by reason of such purchase.

Section 17. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.

Section 18. Governing Law Provisions. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York applicable to agreements made and to be performed in such state. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the Borough of Manhattan in the City of New York or the courts of the State of New York in each case located in the Borough of Manhattan in the City of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. Each party not located in the United States irrevocably appoints Corporation Service Company, which currently maintains a New York City office at 1180 Avenue of the Americas, Xxxxx 000, Xxx Xxxx, Xxx Xxxx 00000, Xxxxxx Xxxxxx of America, as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the Borough of Manhattan in the City of New York.

With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

Section 19. Failure of One or More of the Selling Shareholders to Sell and Deliver Offered ADSs. If one or more of the Selling Shareholders shall fail to sell and deliver to the Underwriters the Offered ADSs to be sold and delivered by such Selling Shareholders at the First Closing Date pursuant to this Agreement, then the Underwriters may at their option, by written notice from the Representatives to the Company and the Selling Shareholders, either (i) terminate this Agreement without any liability on the part of any Underwriter or, except as provided in

Sections 4, 7, 9 and 10 hereof, the Company or the other Selling Shareholders, or (ii) purchase the shares which the Company and other Selling Shareholders have agreed to sell and deliver in accordance with the terms hereof. If one or more of the Selling Shareholders shall fail to sell and deliver to the Underwriters the Offered ADSs to be sold and delivered by such Selling Shareholders pursuant to this Agreement at the First Closing Date or the applicable Option Closing Date, then the Underwriters shall have the right, by written notice from the Representatives to the Company and the Selling Shareholders, to postpone the First Closing Date or the applicable Option Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

Section 20. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Table of Contents and the Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

All payments made by the Company or any Selling Shareholder under this Agreement, if any, will be made without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature unless the Company or Selling Shareholder is or becomes required by law to withhold or deduct such taxes, duties, assessments or other governmental charges. In such event, the Company or Selling Shareholder, as appropriate, will pay such additional amounts as will result, after such withholding or deduction, in the receipt by each Underwriter of the amounts that would otherwise have been receivable in respect thereof.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification provisions of Section 9 and the contribution provisions of Section 10, and is fully informed regarding said provisions. Each of the parties hereto further acknowledges that the provisions of Sections 9 and 10 hereto fairly allocate the risks in light of the ability of the parties to investigate the Company, its affairs and its business in order to assure that adequate disclosure has been made in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, each Road Show, each free writing prospectus and the Prospectus (and any amendments and supplements thereto), as required by the Securities Act and the Exchange Act.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.
