Xxxxxxx, Xxxxx & Co.

00 Xxxxx Xxxxxx

Xxx Xxxx, Xxx Xxxx 00000

Ladies and Gentlemen:

Endurance Specialty Holdings Ltd., an exempted company incorporated in Bermuda as a holding company (the “Company”), confirms its agreement with Xxxxxxx, Sachs & Co. (the “Underwriter”) with respect to the issue and sale by the Company and the purchase by the Underwriter of up to 6,079,000 ordinary shares, par value U.S. $1.00 per share, of the Company (the “Ordinary Shares”). The Underwriter shall initially purchase 3,039,500 Ordinary Shares from the Company (such Ordinary Shares being referred to herein as the “Initial Securities”) and, conditional upon and following the delivery by it of the Resale Notice (as defined herein), shall purchase the remaining 3,039,500 Ordinary Shares (such additional Ordinary Shares being referred to herein as the “Additional Securities”), in each case subject to the terms and conditions set forth herein. The Initial Securities and the Additional Securities are referred to collectively herein as the “Securities”.

The Company understands that the Underwriter proposes to make a public offering of the Securities as soon as it deems advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “1933 Act”) a registration statement on Form S-3 (No. 333-125457) including a prospectus (the “Basic Prospectus”), relating to certain of its debt securities, preference shares, Ordinary Shares (including the Securities), depositary shares, warrants, stock purchase contracts and stock purchase units to be issued by the Company and trust preferred securities to be issued by Endurance Holdings Capital Trust I and Endurance Holdings Capital Trust II and to be guaranteed by the Company from time to time in accordance with Rule 415 under the 1933 Act. Such registration statement was declared effective on June 10, 2005. The Company shall file with the Commission pursuant to Rule 424 under the 1933 Act a prospectus supplement specifically relating to the Securities (the “Prospectus Supplement”). The registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A under the 1933 Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement” and as used herein, the term “Prospectus” means the Basic Prospectus as supplemented by the Prospectus Supplement in the form first used to confirm sales of the Securities. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus. References herein to the Registration Statement, the Basic Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement or the

Prospectus shall be deemed to refer to and include any documents filed by the Company under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (the “Exchange Act”) subsequent to the date of this Agreement which are deemed to be incorporated by reference therein. For purposes of this Agreement, the term “Effective Time” means the date and time the Registration Statement became effective.

SECTION 1

Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to the Underwriter as of the date hereof and as of the Closing Time and the Additional Closing Time, each as referred to in Section 2(c) hereof, and agrees with the Underwriter, as follows:

(i) Compliance with Registration Requirements. The Registration Statement has become effective under the 1933 Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission.

At the respective times the Registration Statement and any post-effective amendments thereto became effective and at the Closing Time and the Additional Closing Time, the Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendments or supplements thereto, at the time the Prospectus or any amendments or supplements thereto were issued and at the Closing Time and the Additional Closing Time, included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. If Rule 434 is used, the Company will comply with the requirements of Rule 434 and the Prospectus shall not be “materially different”, as such term is used in Rule 434, from the prospectus included in the Registration Statement at the time it became effective. The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or the Prospectus made in reliance upon and in conformity with information furnished to the Company in writing by the Underwriter expressly for use in the Registration Statement or the Prospectus.

Each prospectus used in connection with the offering and filed as part of the Registration Statement as originally filed or as part of any amendment thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so filed in all material respects with the 1933 Act and the Prospectus delivered to the Underwriter for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T.

(ii) Independent Accountants. The accountants who certified the financial statements and supporting schedules included in the Registration Statement, and audited the Company’s internal control over financial reporting and management’s assessment thereof, are independent public accountants as required by the 1933 Act.

(iii) Financial Statements. The consolidated financial statements included or incorporated by reference in the Registration Statement and the Prospectus, together with the related schedules and notes present fairly, in all material respects, the financial position of the

Company and its consolidated subsidiaries at the dates indicated and the statement of operations, shareholders’ equity and cash flows of the Company and its consolidated subsidiaries for the periods specified; except as otherwise disclosed in the Registration Statement and Prospectus, said balance sheet, statement of income and financial statements have been prepared in conformity with United States generally accepted accounting principles (“U.S. GAAP”) applied on a consistent basis throughout the periods involved. The supporting schedules included or incorporated by reference in the Registration Statement present fairly, in all material respects, in accordance with U.S. GAAP the information required to be stated therein. The selected financial data and the summary financial information included or incorporated by reference in the Prospectus and Registration Statement present fairly, in all material respects, the information shown therein and have been compiled on a basis consistent with that of the audited financial statements included or incorporated by reference in the Registration Statement.

(iv) No Material Adverse Change in Business. Since the respective dates as of which information is given in the Registration Statement and the Prospectus, except as otherwise stated therein, (A) there has been no material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business (a “Material Adverse Effect”), (B) there have been no transactions entered into by the Company or any of its subsidiaries, other than those in the ordinary course of business, which are material with respect to the Company and its subsidiaries considered as one enterprise, and (C) there has been no dividend or distribution of any kind declared, paid or made by the Company on any class of its share capital, other than the $0.25 per ordinary share dividend paid on September 30, 2005 to shareholders of record of the Company as of September 16, 2005.

(v) Good Standing of the Company. The Company has been duly incorporated and is validly existing as an exempted company in good standing under the laws of Bermuda and has the necessary corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus and to enter into and perform its obligations under this Agreement; and the Company is duly qualified as a foreign company or corporation 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 where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

(vi) Good Standing of Subsidiaries. Each of Endurance Specialty Insurance Ltd. (“Endurance Bermuda”), Endurance Reinsurance Corporation of America (“Endurance U.S.”) and Endurance Worldwide Insurance Limited (“Endurance U.K.”) (each, a “Designated Subsidiary” and collectively, the “Designated Subsidiaries”) has been duly incorporated or organized and is validly existing as a company or corporation in good standing under the laws of the jurisdiction of its incorporation or organization and has the necessary corporate power to own, lease and operate its properties and to conduct its business as described in the Prospectus and is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect; except as otherwise disclosed in the Registration Statement, all of the issued and outstanding share capital or capital stock of each subsidiary of the Company has been duly authorized and validly issued, is fully paid and non assessable and is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; none of the outstanding shares of share capital or capital stock of any Designated Subsidiary was issued in violation of the

(“Endurance Marketing”), Endurance Specialty Marketing Corp. of Illinois (“Endurance Illinois”), Traders & Pacific Insurance Company (“Traders & Pacific”), Endurance U.S. Specialty Services Corporation (“Endurance Specialty Services”) and Endurance Elite Assurance Corp.

Each of Endurance U.K. Holdings, Endurance U.S. Holdings, Endurance Services, Endurance Marketing, Endurance Illinois, Traders & Pacific, Endurance Specialty Services and Endurance Elite has been duly organized and is validly existing as a company or corporation in good standing under the laws of the jurisdiction of its organization or incorporation and has the necessary corporate power to own, lease and operate its properties and to conduct its business to the extent described in the Prospectus.

Based solely on the Certified Registers of Members: (A) all of the currently issued and outstanding shares of share capital of both the Company (including the Securities) and the Designated Subsidiaries have been duly and validly authorized and issued and are fully paid and non-assessable (which term when used herein shall mean that no further sums are required to be paid by the holders thereof in connection with the issue of such shares) (collectively, the “Outstanding Shares”); (B) all of the currently issued and outstanding shares of the subsidiaries are held directly or indirectly by the Company and are free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; and (C) none of the Outstanding Shares were issued in violation of the preemptive or other similar rights of any member of the Company or the Designated Subsidiaries. Except as set forth in the Prospectus, there are no outstanding options, warrants or other rights requiring the issuance of, and there are no commitments, plans or arrangements to issue, any shares of share capital of the Company or any of its subsidiaries or any security convertible into or exchangeable or exercisable for any shares of share capital of the Company or any of it subsidiaries. The form of certificates for the Securities conforms to the requirements of the laws of Bermuda and the New York Stock Exchange (“NYSE”).

(viii) Authorization and Execution of Agreement. This Agreement has been duly authorized, executed and delivered by the Company.

(ix) Authorization and Description of Securities. The Securities have been duly authorized, and when delivered by the Company in accordance with the terms of this Agreement, will be validly issued, fully paid and non assessable, and will not have been issued in violation of or subject to any preemptive or similar rights that entitle or will entitle any person to acquire any Ordinary Shares to be issued in connection therewith from the Company; the Ordinary Shares conform, in all material respects, to all statements relating thereto contained in the Prospectus and such description conforms, in all material respects, to the rights set forth in the instruments defining the same; no holder of the Securities will be subject to personal liability by reason of being such a holder.

(x) Absence of Defaults and Conflicts. Neither the Company nor any of its Designated Subsidiaries is in violation of its charter, memorandum of association, bye-laws, by-

laws or similar incorporation or organizational documents or in violation or default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any subsidiary is subject (collectively, “Agreements and Instruments”) except for such defaults under the material Agreements and Instruments that would not result in a Material Adverse Effect; and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated in this Agreement (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Prospectus under the caption “Use of Proceeds”), and in the Registration Statement and compliance by the Company with its obligations under this Agreement do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any subsidiary pursuant to, the Agreements and Instruments (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter, memorandum of association, bye-laws, by-laws or similar organizational documents of the Company or any subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company or any subsidiary or any of their assets, properties or operations (except for such violations that would not result in a Material Adverse Effect). As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness that is material to the operations or financial results of the Company (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 subsidiary.

(xi) Financial Assistance. On the date hereof and at the Closing Time and the Additional Closing Time, the Company is and will be in compliance with Section 39 and/or entitled to one or more of the exclusions therefrom set forth in Section 39A of the Companies Xxx 0000 of Bermuda (the “Companies Act”).

(xii) Absence of Labor Dispute. No labor dispute with the employees of the Company or any Designated Subsidiary exists or, to the knowledge of the Company, is imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or any Designated Subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case, may reasonably be expected to result in a Material Adverse Effect.

(xiii) Absence of Proceedings. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened or against the Company or any subsidiary or the properties or assets thereof, which is required to be disclosed in the Registration Statement (other than as disclosed therein), or which would reasonably be expected to result in a Material Adverse Effect, or which would reasonably be expected to materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company of its obligations hereunder; the aggregate of all pending legal or governmental proceedings to which the Company or any subsidiary is a party or of which any of their respective property or assets is the subject which are not described in the Registration Statement, including ordinary routine litigation incidental to the business, would not reasonably be expected to result in a Material Adverse Effect.

(xiv) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement or the Prospectus or to be filed or incorporated by reference as exhibits thereto which have not been so described, filed or incorporated by reference as required.

(xv) Possession of Intellectual Property. The Company and the Designated Subsidiaries own or possess, or can acquire on reasonable terms, adequate patents, patent rights, licenses, inventions, copyrights, know how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures), trademarks, service marks, trade names or other intellectual property (collectively, “Intellectual Property”) necessary to carry on the business now operated by them except where the failure to own or possess, or to be able to acquire such Intellectual Property, would not have a Material Adverse Effect, and neither the Company nor any of the Designated Subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with asserted rights of others with respect to any Intellectual Property or of any facts or circumstances which would render any Intellectual Property invalid or inadequate to protect the interest of the Company or any of its Designated Subsidiaries therein, and which infringement or conflict (if the subject of any unfavorable decision, ruling or finding) or invalidity or inadequacy, singly or in the aggregate, would result in a Material Adverse Effect.

(xvi) Absence of Further Requirements. No filing with, or authorization, approval, consent, license, order, registration, exemption, qualification or decree of, any court or governmental authority or agency or any sub-division thereof is necessary or required for the performance by the Company of its obligations hereunder, in connection with the offering or sale of the Securities under this Agreement or the consummation of the transactions contemplated by this Agreement, except (i) such as have been already obtained or as may be required under the 1933 Act and state securities or blue sky laws, (ii) such as have been obtained from the Bermuda Monetary Authority and (iii) the Prospectus will be filed at the Registrar of Companies in Bermuda pursuant to the laws of Bermuda.

(xvii) Licenses and Permits. Each of the Company and its subsidiaries possesses all consents, authorizations, approvals, orders, licenses, certificates, or permits issued by any regulatory agencies or bodies (collectively, “Permits”) which are necessary to conduct the business now conducted by it as described in the Prospectus, except where the failure to possess such Permits, individually or in the aggregate, would not have a Material Adverse Effect; all of such Permits are valid and in full force and effect, except where the invalidity of such Permits or the failure to be in full force and effect, individually or in the aggregate, would not have a Material Adverse Effect. There is no pending, or to the Company’s knowledge, threatened action, suit, proceeding or investigation against or involving the Company and its subsidiaries (and the Company knows of no reasonable basis for any such action, suit, proceeding or investigation) that individually or in the aggregate would reasonably be expected to lead to the revocation, modification, termination, suspension or any other material impairment of the rights of the holder of any such Permit which revocation, modification, termination, suspension or other material impairment would have a Material Adverse Effect. Except as otherwise described in the Prospectus, no insurance regulatory authority has issued to the Company or any Designated Subsidiary any order impairing, restricting or prohibiting (A) the payment of dividends by the Company or any of its Designated Subsidiaries, (B) the making of a distribution on any Designated Subsidiary’s capital stock, (C) the repayment to the Company of any loans or advances to any Designated Subsidiaries from the Company or (D) the transfer of any Designated Subsidiaries property or assets to the Company or any other subsidiary of the Company.

(xviii) Compliance with Applicable Laws. Neither the Company nor any of its Designated Subsidiaries is in violation or default of any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency or other governmental body having jurisdiction over the Company or any such Designated Subsidiary or any of its properties, as applicable, except for such violations or defaults which, individually or in the aggregate, would not have a Material Adverse Effect.

(xix) Tax Liabilities and Reserves. Any tax returns required to be filed by the Company or any of its subsidiaries in any jurisdiction have been filed and any taxes, including any withholding taxes, excise taxes, penalties and interest, assessments and fees and other charges due or claimed to be due from such entities have been paid, other than any of those being contested in good faith and for which adequate reserves have been provided or any of those currently payable without penalty or interest, except to the extent that the failure to so file or pay would not result in a Material Adverse Effect.

(xx)	Internal Controls.

(A) The Designated Subsidiaries 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 authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (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 the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(B) The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act) designed by, or under the supervision of, the Company’s principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Company’s internal control over financial reporting was effective as of the end of the quarter ended June 30, 2005 and the Company was not aware of any material weaknesses in its internal control over financial reporting at such time. As of the date hereof, to the knowledge of the Company, the Company’s internal control over financial reporting is effective and the Company is not aware of any material weakness in its internal control over financial reporting, it being understood that the management of the Company has not conducted an evaluation of the effectiveness of the Company's internal control over financial reporting for any period after June 30, 2005.

(xxi) Disclosure Controls and Procedures. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Exchange Act) that have been designed to ensure that material information relating to the Company and its consolidated subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within those entities; such disclosure controls and procedures were effective as of the end of the quarter ended June 30, 2005. As of the date hereof, to the knowledge of the Company, such disclosure controls and procedures are effective, it being understood that the

management of the Company has not conducted an evaluation the effectiveness of the Company's disclosure controls and procedures for any period after June 30, 2005.

(xxii) Property and Leases. Neither the Company nor any of its Designated Subsidiaries hold title to any real property. All of the leases and subleases under which the Company or any of its Designated Subsidiaries holds properties described in the Prospectus, are in full force and effect, and neither the Company nor any Designated Subsidiary has any notice of any claim of any sort that has been asserted by anyone adverse to the rights of the Company or any subsidiary under any of the leases or subleases mentioned above, or affecting or questioning the rights of the Company or such Designated Subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease, except where the failure to have such leases in full force and effect or the failure to have any such notice of any such claim would not, individually or in the aggregate, have a Material Adverse Effect.

(xxiii) Investment Company Act. The Company is not and, solely after giving effect to the offer and sale of the Securities and the application of the proceeds thereof as described under the caption “Use of Proceeds” in the Prospectus, will not be an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

(xxiv) Stamp Duty, Excise Tax, Etc. Neither the Underwriter nor any subsequent purchasers of the Securities (other than purchasers resident in Bermuda for Bermuda exchange control purposes) is subject to any stamp duty, transfer, excise or similar tax imposed in Bermuda in connection with the issuance, offering or sale of the Securities to the Underwriter or to any subsequent purchasers.

(xxv) Currency Exchange Control. There are no currency exchange control laws or withholding taxes, in each case of Bermuda, that would be applicable to the payment of dividends on the Securities by the Company (other than as may apply to residents of Bermuda for Bermuda exchange control purposes).

(xxvi) Registration Rights. Except as disclosed in the Prospectus and the Registration Statement, there are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement or otherwise registered by the Company under the 1933 Act.

(xxvii) No Ratings Downgrade. Except as disclosed in the Prospectus and the Registration Statement, the Company has no knowledge of any threatened or pending downgrading of any of its or its subsidiaries’ financial strength rating by Standard & Poor’s Rating Services, Xxxxx’x Investor Service and A.M. Best Company Inc., the only “nationally recognized statistical rating organizations,” as such term is defined for purposes of Rule 463(g)(2) under the 1933 Act which currently has publicly released a rating of the financial strength of the Company or any of its subsidiaries.

(b) Officer’s Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries delivered to the Underwriter or to counsel for the Underwriter shall be deemed a representation and warranty by the Company to the Underwriter as to the matters covered thereby.

(c) Notice to the Underwriter. During the period when a prospectus is required by the 1933 Act or the Exchange Act to be delivered in connection with sales of the Securities (the “Prospectus Delivery Period”), the Company will advise the Underwriter promptly, and confirm such advice in writing, (i) when any post-effective amendment to the Registration Statement has been filed or becomes effective; (ii) when any supplement to the Prospectus or any amendment to the Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Prospectus or the initiation or threatening of any proceeding for that purpose; and (v) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Securities for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of the Prospectus or suspending any such qualification of the Securities and, if any such order is issued, will obtain as soon as reasonably possible the withdrawal thereof.

(f) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriter or counsel for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the reasonable opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement any Prospectus in order to comply with the requirements of the 1933 Act, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriter such number of copies of such amendment or supplement as the Underwriter may reasonably request.

(g) Blue Sky Qualifications.

In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement.

(h) Rule 158.

transaction described in clause (i) or (ii) above is to be settled by delivery of its Ordinary Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to the Securities to be sold to the Underwriter hereunder. The Company may, however, (i) grant options to purchase Ordinary Shares, restricted share units or other equity based compensation pursuant to its existing equity compensation plans, (ii) issue Ordinary Shares upon the conversion of outstanding class A shares, the exercise of warrants for Ordinary Shares or class A shares, or the exercise of outstanding options, restricted share units and other equity incentive awards under the existing equity compensation plans and (iii) after 15 days following the Additional Closing Time, file a registration statement with the Commission pursuant to Rule 415 under the 1933 Act for the registration of Ordinary Shares, preference shares, debt securities, warrants and other securities, commonly referred to as a “universal shelf.”

(m) No Advisory or Fiduciary Relationship. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriter, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction the Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company, or its stockholders, creditors, employees or any other party, (iii) the Underwriter has not assumed or will not 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 the Underwriter has advised or is currently advising the Company on other matters) and the Underwriter has no obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriter and its respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (v) the Underwriter has 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. The Company agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriter with respect to the subject matter hereof.

The Company and the Underwriter hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 6

Indemnification.

(a) Indemnification of Underwriter. The Company will indemnify and hold harmless the Underwriter against any losses, claims, damages or liabilities, joint or several, to which the Underwriter may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or

liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are 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; and will reimburse the Underwriter for any legal or other expenses reasonably incurred by the Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall 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 or omission or alleged omission made in the Registration Statement or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein.

(b) Indemnification of Company, Directors and Officers. The Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus, or any amendment or supplement thereto, or arise out of or are 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 or the Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under subsection (a) and (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection to the extent it is not materially prejudiced as a result thereof. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Underwriter, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) Control Persons. The obligations of the Company under this Section 6 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter or within the meaning of the Act and the obligations of the Underwriter under this Section 6 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

SECTION 7

Contribution.

If the indemnification provided for in Section 6 is unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to in Section 6, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 6(c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table 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 on the one hand or the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public 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. 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 Section 7, each person, if any, who controls the Underwriter within the meaning of the Act shall have the same rights to contribution as the Underwriter, and each officer and director of the Company, and each person, if any, who controls the Company within the meaning of the Act or shall have the same rights to contribution as the Company. The Underwriter' obligations in this Section 7 to contribute are several in proportion to their respective underwriting obligations and not joint.

SECTION 8 Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Underwriter.

SECTION 9

Termination of Agreement.

(a) Termination; General. The Underwriter may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time or, as applicable, the Additional Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus (exclusive of any supplement thereto), any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriter, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Initial Securities and the Additional Securities, as the case may be, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the American Stock Exchange or the NYSE or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either federal or New York authorities.
