(ii) The Company (i) will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus unless the Underwriter approve its use in writing prior to first use; provided that the prior written consent of the Underwriter shall be deemed to have been given in respect of the Free Writing Prospectus(es) included in Schedule III and any electronic road show, (ii) has treated and will treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (iii) will comply with the requirements of Rules 163, 164 and 433 under the Act applicable to any Permitted Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping.

(iii) The Company will advise the Underwriter promptly (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for such period as delivery of a prospectus by an Underwriter may be required by the Act (including circumstances in which such requirement may be satisfied pursuant to Rule 172) (the “Effectiveness Period”).

(vii) As soon as practicable, the Company will make generally available to its security holders and to the Underwriter an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(viii) The Company will deliver to the Underwriter and counsel for the Underwriter, without charge, as many copies of any Preliminary Prospectus or any Issuer Free Writing Prospectus, the Prospectus, and the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested), including documents incorporated by reference therein and all amendments thereto as may reasonably be requested by the Underwriter. The Selling Shareholders will pay the expenses of printing or other production of all documents related to the offering for the duration of the Effectiveness Period.

(ix) If, during the Effectiveness Period, any event shall occur as a result of which, in the judgment of the Company, it becomes necessary to amend or supplement the Registration Statement or the Prospectus in order to make the statements therein (in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, in the case of the Prospectus), not misleading, or, if it is necessary at any time to amend or supplement the

20

Registration Statement, file a new Registration Statement or supplement the Prospectus to comply with the Act or the Exchange Act, the Company will promptly notify the Underwriter and either (i) prepare as soon as reasonably practicable and file with the Commission, subject to Section 5(a)(i) of this Agreement, an appropriate amendment to the Registration Statement and/or supplement to the Prospectus or (ii) prepare as soon as reasonably practicable and file with the Commission, subject to Section 5(a)(i) of this Agreement, an appropriate filing under the Exchange Act that shall be incorporated by reference in the Prospectus and the Registration Statement, so that each of the Prospectus and the Registration Statement as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus and the Registration Statement will comply with the law, (iii) use commercially reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Underwriter in such quantities as the Underwriter may reasonably request.

(x) If the General Disclosure Package is being used to solicit offers to buy the Securities at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company will promptly notify the Underwriter and either (i) prepare as soon as reasonably practicable, and subject to Section 5(a)(i) of this Agreement, file with the Commission (if required) and furnish to the Underwriter an appropriate amendment or supplement to the General Disclosure Package or (ii) prepare as soon as reasonably practicable and, subject to Section 5(a)(i) of this Agreement, file with the Commission an appropriate filing under the Exchange Act that shall be incorporated by reference in the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

(xi) The Company will not take, directly or indirectly, any action designed to cause or result in or that would constitute or that might reasonably be expected to constitute, under the Exchange Act or otherwise, stabilization or manipulation of the price of the Ordinary Shares to facilitate the sale or resale of the Securities.

(xii) For a period of 30 days after the date of the Prospectus, the Company will not (i) offer, pledge, sell, contract to sell, sell any option or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to, any Ordinary

21

Shares or any securities convertible into or exercisable or exchangeable for Ordinary Shares, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Ordinary Shares or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Ordinary Shares or such other securities, in cash or otherwise, without the prior written consent of the Underwriter, other than any Ordinary Shares issued upon the exercise of options or the vesting of equity awards granted under terms of any employee plan, benefit or compensation arrangement or employment agreement described in the Registration Statement, the General Disclosure Package and the Prospectus (in each case, exclusive of any amendment or supplement thereto).

(xiii) The Company will use commercially reasonable efforts to maintain the listing of the Ordinary Shares on the NYSE.

(b) The Selling Shareholders agree with the Company and the Underwriter that the Selling Shareholders will pay all expenses incidental to the performance of or compliance with this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Company; the fees and disbursements of counsel for the Company; the cost of printing and delivering to, or as requested by, the Underwriter copies of the Registration Statement, any Preliminary Prospectuses, any Issuer Free Writing Prospectuses, and the Prospectus (including all exhibits, amendments and supplements thereto); the filing fees and expenses (including legal fees and disbursements) incident to securing any required review by FINRA of the terms of the sale of the Securities; the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Ordinary Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Underwriter may designate; the reasonable fees and expenses of the counsel to the Selling Shareholders; the cost of preparing stock certificates, including any cost related to printing, authentication, issuance and delivery thereof; the cost and charges of any transfer agent and any registrar; all expenses and application fees related to the listing of the Securities on the NYSE; and its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties).

(a) The Company will indemnify and hold harmless the Underwriter, its directors, officers, employees, and agents and the affiliates of the Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which any such person or entity may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order 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, in the Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, any other Free Writing Prospectus or “written communication” (as defined in Rule 405 under the Act), the General Disclosure Package (or, in each case, any amendment or supplement to any of the foregoing, including the General

26

Disclosure Package as subsequently amended or supplemented), or caused by any omission or alleged omission to state therein 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 will reimburse each indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission made in reliance upon and in conformity with the Underwriter Information or the Selling Shareholder Information.

(b) Each Selling Shareholder will indemnify and hold harmless the Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which any such person or entity may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or (ii) or any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, in the Prospectus, any Issuer Free Writing Prospectus, or the General Disclosure Package (or, in each case, any amendment or supplement to any of the foregoing, including the General Disclosure Package that has subsequently been amended or supplemented), or caused by any omission or alleged omission to state therein 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 relates to the Selling Shareholder Information; and will reimburse each indemnified party for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred.

(c) The Underwriter will indemnify and hold harmless the Company, its directors, officers, employees, agents and affiliates and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the Selling Shareholders and each person, if any, who controls the Selling Shareholders within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities to which any such person or entity may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order 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 Prospectus or the General Disclosure Package (or, in each case, any amendment or

27

supplement to any of the foregoing, including the General Disclosure Package as subsequently amended or supplemented) or caused by any omission or alleged omission to state therein 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 reliance upon and in conformity with the written information furnished to the Company by or on behalf of such Underwriter expressly for use in the Registration Statement, the General Disclosure Package and the Prospectus (the “Underwriter Information”) and will reimburse any legal or other expenses reasonably incurred by an indemnified party in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; it being understood and agreed upon that the Underwriter Information consists only of (i) the name of the Underwriter, (ii) the sentence related to concessions and reallowances and (iii) the information under the heading “Price Stabilization, Short Positions and Penalty Bids” under the caption “Underwriting” in the Prospectus.

(d) Promptly after receipt by an indemnified party under this Section 7 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 paragraph (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party (i) shall not relieve it from any liability that it may have under paragraph (a), (b) or (c) above except and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a), (b) or (c) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than one local counsel in each jurisdiction in which proceedings have been brought, if not appointed by the indemnifying party or retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of

28

the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified person.

(e) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) for which indemnification is provided by an indemnifying party therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (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 Underwriter on the other, respectively, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or if unavailable for any reason, 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, or the Underwriter, on the other, respectively, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof) from the offering of the Securities 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 Underwriter, on the other, shall be deemed to be in the same respective proportions as the net proceeds (after deducting underwriting commissions and discounts, but before deducting expenses) received by the Selling Shareholders from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriter in connection therewith, in each case as set forth on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Shareholders, on the one hand, and the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). The Company, the Selling Shareholders and the Underwriter agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this subsection (e), (1) no Underwriter shall be required to contribute any amount in excess of the amount by which the underwriting

29

discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (2) the Selling Shareholders shall not be required to contribute any amount in excess of the amount by which (A) the net proceeds received by the Selling Shareholders from the sale of Securities exceeds (B) the amount of any damages which the Selling Shareholders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this subsection (e), (i) each person who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and director, officer, employee, agent and affiliate of an Underwriter shall have the same rights to contribution as such Underwriter, (ii) each person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and each director, officer, employee, agent and affiliate of the Company shall have the same rights to contribution as the Company and (iii) each person who controls the Selling Shareholders within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and each director, officer, employee, agent and affiliate of the Selling Shareholders shall have the same rights to contribution as the Selling Shareholders, subject in each case to the applicable terms and conditions of this subsection (e).

(f) The obligations of the Company and the Selling Shareholders under this Section shall be in addition to any liability which the Company and the Selling Shareholders may otherwise have.

8. Termination; Survival of Certain Representations and Obligations; Certain Expenses. If any of the conditions set forth in Section 6 hereof are not satisfied on or prior to the Closing Date or the parties hereto breach their obligations hereunder, this Agreement and the obligations hereunder may be terminated by the Underwriter in its absolute discretion. The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any controlling person of the foregoing, or by or on behalf of the Company or its directors or officers or by or on behalf of the Selling Shareholders or their directors or officers and (iii) delivery of and payment for the Securities under this Agreement and the sale of the Securities. If this Agreement is terminated pursuant to this Section 8 or if for any reason the purchase of the Securities by the Underwriter is not consummated, each of the Selling Shareholders and the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 7 and the respective obligations of the Company, the Selling Shareholders and the Underwriter pursuant to Section 7 shall remain in effect, and if any Securities have been purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. In addition, if the purchase of the Securities by the Underwriter is not consummated for any reason, other than the termination of this Agreement pursuant to Section 9 hereof, the Selling Shareholders will reimburse the Underwriter for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Securities. The provisions of Sections 7 and Section 8 hereof shall survive the termination or cancellation of this Agreement.

Each of the Company and the Selling Shareholders agrees that it will not claim that any Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Selling Shareholders, in connection with such transaction or the process leading thereto. Furthermore, the Company and the Selling Shareholders agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriter has advised or is currently advising the Company or the Selling Shareholders on related or other matters).

31

16. Jurisdiction. The Company and the Selling Shareholders hereby submit to the exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby and irrevocably and unconditionally waive any objections to the laying of venue of any such suit or proceeding arising out of or relating to this Agreement or any transactions contemplated hereby in a Federal or state court in the Borough of Manhattan in The City of New York, and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

In the event that the Underwriter is a Covered Entity or a BHC Act Affiliate of the Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against the Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
