(ee) No labor disturbance by the employees of the Guarantor or its subsidiaries exists or, to the knowledge of the Guarantor, is imminent that could reasonably be expected to have a Material Adverse Effect.

reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorization, (B) transactions are recorded as necessary to permit preparation of the Guarantor’s and the Company’s financial statements in conformity with accounting principles generally accepted in the United States and to maintain accountability for its assets, (C) access to the Guarantor’s and the Company’s assets is permitted only in accordance with management’s general or specific authorization and (D) the recorded accountability for the Guarantor’s and the Company’s assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(jj) (i) Each of the Guarantor and its subsidiaries have established and maintain disclosure controls and procedures (as such term is defined in Rule 13a-15 under the Exchange Act), (ii) such disclosure controls and procedures are designed to ensure that the information required to be disclosed by the Guarantor and its subsidiaries and the Company and its subsidiaries in the reports they will file or submit under the Exchange Act is accumulated and communicated to management of the Guarantor and its subsidiaries and the Company and its subsidiaries, including their respective principal executive officers and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure to be made and (iii) such disclosure controls and procedures are effective in all material respects to perform the functions for which they were established.

(n) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the NASDAQ Stock Market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or Bermuda or there shall have been a declaration of a national emergency or war by the United States or Bermuda; (iv) there shall have occurred such a material adverse change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such), as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the public offering or delivery of the Securities being delivered on the Closing Date on the terms and in the manner contemplated in the Pricing Disclosure Package and Prospectus.

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriters.

8. Indemnification and Contribution.

(a) The Company and the Guarantor shall jointly and severally indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Securities), to which that Underwriter, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) used or referred to by any Underwriter, or (D) any “road show” (as defined in Rule 433) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”), (ii) the omission or alleged omission to state in the Registration Statement or in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, or any Non-Prospectus Road Show in the light of the circumstances under which they were made, any material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company and the Guarantor shall not be liable in any such case to

the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, or any Non-Prospectus Road Show, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company or the Guarantor through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability which the Guarantor or the Company may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, the Guarantor, their respective directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company or the Guarantor, officers and employees, and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to the purchases and sales of Securities), to which the Company, the Guarantor or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Base Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Base Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company or the Guarantor through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Company, the Guarantor or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons

who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other, from the offering of the Securities 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 Guarantor, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, 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 Underwriters, 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 and the Guarantor, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Guarantor and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), 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 8(d), 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 were offered to investors 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 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 as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Company and the Guarantor acknowledge and agree that the statements regarding delivery of the Securities by the Underwriters set forth on the cover page of, and the sentences concerning (i) discounts and allowances; (ii) the list of Underwriters and (iii) the market-making and stabilizing transactions by the Underwriters appearing under the caption “Underwriting” in the Pricing Disclosure Package and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company or the Guarantor by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

9. Defaulting Underwriters.

(a) If any Underwriter defaults in its obligation to purchase the principal amount of the Securities which it has agreed to purchase under this Agreement, the non-defaulting Underwriters will be obligated to purchase (in the respective proportions which the principal amount of the Securities set forth opposite the name of each non-defaulting Underwriter in Schedule I hereto bears to the total principal amount of the Securities less the principal amount of the Securities the defaulting Underwriter agreed to purchase set forth in Schedule I hereto) the principal amount of the Securities which the defaulting Underwriter agreed but failed to purchase; except that the non-defaulting Underwriters will not be obligated to purchase any of the Securities if the total principal amount of the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase exceed 9.09% of the total principal amount of the Securities, and any non-defaulting Underwriters will not be obligated to purchase more than 110% of the principal amount of the Securities set forth opposite its name in Schedule I hereto. If the foregoing maximums are exceeded, the non-defaulting Underwriters, and any other underwriters reasonably satisfactory to the Representatives who so agree, will have the right, but will not be obligated, to purchase (in such proportions as may be agreed upon among them) all of the Securities. If the non-defaulting Underwriters or the other underwriters reasonably satisfactory to the Representative do not elect to purchase the Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Guarantor and the Company, except for the indemnity and contribution agreements of the Guarantor and the Company and the Underwriters contained in Section 8 of this Agreement. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter pursuant to this Section 9.

(b) If the non-defaulting Underwriters or the other underwriters satisfactory to the Representatives are obligated or agree to purchase the Securities of a defaulting Underwriter, the Representatives may postpone the Closing Date for up to seven full Business Days in order that the Guarantor and the Company may effect any changes that may be necessary in the Registration Statement or the Prospectus or in any other document or agreement, and the Company agrees to file promptly any amendments or any supplements to the Registration Statement or the Prospectus which, in the opinion of the Representatives, may thereby be made necessary.

(c) Nothing contained herein will relieve a defaulting Underwriter of any liability it may have for damages caused by its default.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company and the Guarantor prior to delivery of and payment for the Securities if, prior to that time, any of the events described in Sections 7(l), 7(m) and 7(n) shall have occurred or if the Underwriters shall decline to purchase the Securities for any reason permitted under this Agreement.

11. Reimbursement of Underwriters’ Expenses. If (a) the Company and the Guarantor shall fail to tender the Securities for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company or the Guarantor to perform any agreement on their part to be performed, or because any other condition to the Underwriters’ obligations hereunder required to be fulfilled by the Company or the Guarantor is not fulfilled for any reason or (b) the Underwriters shall decline to purchase the Securities for any reason permitted under this Agreement, the Company and the Guarantor will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Securities, and upon demand the Company and the Guarantor shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 9 by reason of the default of one or more Underwriters, neither the Company nor the Guarantor shall be obligated to reimburse any defaulting Underwriter on account of those expenses.

12. No Fiduciary Duty. The Company and the Guarantor acknowledge and agree that in connection with this offering, sale of the Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company, the Guarantor and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to either the Company or the Guarantor, including, without limitation, with respect to the determination of the public offering price of the Securities, and such relationship between the Company or the Guarantor, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company or the Guarantor shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company and the Guarantor. The Company and the Guarantor hereby waive any claims that the Company or the Guarantor may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

13. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to the Representatives in case of Barclays Capital Inc., 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration (Fax: 646 ###-###-####); and

(b) if to the Company or the Guarantor, shall be delivered or sent by mail or facsimile transmission to OneBeacon Insurance Group, Ltd., 601 Carlson Parkway, Suite 600, Minnetonka, MN 55305, Attention: Maureen A. Phillips, Esq. (Fax: 888 ###-###-####).

(c) Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Company and the Guarantor shall be entitled to act and rely upon any request, consent, notice or agreement given or made by or on behalf of the Underwriters, by the Representatives.

14. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company, the Guarantor and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Company and the Guarantor contained in this Agreement shall also be deemed to be for the benefit of the directors, officers and employees of the Underwriters and each person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act and (B) the indemnity agreement of the Underwriters contained in Section 10(c) of this Agreement shall be deemed to be for the benefit of the directors of the Company and the Guarantor, the officers of the Company and the Guarantor who have signed the Registration Statement and any person controlling the Company and the Guarantor within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 14, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

15. Survival. The respective indemnities, representations, warranties and agreements of the Company, the Guarantor and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

16. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “Business Day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” has the meaning set forth in Rule 405.

17. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

18. Counterparts. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Guarantor and the Underwriters, or any of them, with respect to the subject matter hereof. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

19. WAIVER OF JURY TRIAL. WAIVER OF JURY TRIAL. THE GUARANTOR, THE COMPANY AND EACH OF THE UNDERWRITERS 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.

20. Authorized Agent. The Guarantor irrevocably (i) agrees that any legal suit, action or proceeding against the Guarantor brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any United States federal or state court in the city of New York, State of New York, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and (iii) submit to the exclusive jurisdiction of such courts in any such suit, action or proceeding. The Guarantor has appointed Maureen A. Phillips, Esq. as its

authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in the any United States federal or state court in the city of New York, State of New York by any Underwriter or by any person who controls any Underwriter, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. The Guarantor represents and warrants that the Authorized Agent has agreed to act as such agent for service of process and agree to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to the Guarantor shall be deemed, in every respect, effective service of process upon the Guarantor.
