(d)           Upon termination of this Agreement and settlement in full of amounts owing to West End Bermuda in respect of this Agreement, West End Bermuda shall deliver to Flagstone, at Flagstone’s expense, all books, records, data and reports (whether print or electronic) used or prepared exclusively in relation to the provision of the Services, to the extent that West End Bermuda is legally entitled to do so.

(e)           Sections 5, 13 and 18 shall survive any termination of this Agreement.

5.             Dispute Resolution. In the event any dispute arises under this Agreement, the parties hereto agree to negotiate in good faith to resolve such dispute prior to seeking relief in a court of law. Either Flagstone, on the one hand or West End Bermuda, on the other, may at any time deliver a notice to any other party that it wishes to refer a dispute to a senior executive of Flagstone and the Compliance Officer of West End Bermuda. Following receipt of such notice Flagstone, on the one hand and West End Bermuda on the other, shall designate one of its senior executives to negotiate in good faith to resolve such dispute within 10 days (or such longer period of time as such officers may agree to in writing). If at the end of such 10 day (or longer if properly extended) period the designated officers have not fully resolved the dispute to their mutual satisfaction, then:

(a) with respect to any dispute relating to charges under Section 3 of this Agreement, the parties shall within a 10 day (or longer if properly extended) period submit such dispute to arbitration by a single arbitrator. The arbitrator shall be an independent accounting firm of international reputation, mutually acceptable to Flagstone and West End Bermuda (or, if the parties are unable to agree upon such an accounting firm, such an accounting firm selected by the parties’ independent accounting firms). In the event, no agreement can be reached as to the identity of the arbitrator, either party may invoke the assistance of the court to appoint an arbitrator pursuant to the provisions of the Arbitration Act 1986.

(b) all other disputes shall be resolved through the courts of Bermuda.

6.             Specific Performance; Liability. (a) It is specifically understood and agreed that any breach of this Agreement by Flagstone or West End Bermuda will result in irreparable injury to the aggrieved party, that the remedy at law alone will be an inadequate remedy for such breach and that Flagstone or West End Bermuda shall be entitled to specific performance of this Agreement, in addition to any other remedy at law or equity.

(b)           Flagstone acknowledges that the Services and transitional assistance are being provided by West End Bermuda pursuant to this Agreement pending an assumption of responsibility for the provision of the Services by Flagstone. Accordingly, all warranties and representations relating to the Services and transitional assistance, whether implied, statutory or otherwise, are hereby excluded to the maximum extent permitted by law, except as expressly set forth in this Agreement (including, without limitation, Section 2 hereof); provided, however, that nothing in this Agreement shall exclude either party’s liability for fraud or dishonesty or liability for death or personal injury arising out of its gross negligence.

(c)           West End Bermuda shall have no liability for any loss to Flagstone or its officers, directors, employees, agents, successors or assigns that arises in relation to the provision of the Services and transitional assistance except with respect to losses resulting from fraud, dishonesty, willful default, bad faith or gross negligence or to the extent the exclusion of such liability is contrary to any applicable laws.

7.             Cooperation; Access. (a)  The parties hereto agree to fully cooperate in good faith with one another in connection with the Services provided under this Agreement.

(b)           Flagstone shall permit West End Bermuda and its employees and agents reasonable access during regular business hours (or otherwise upon agreement) to such data and personnel designated by Flagstone as involved in receiving or overseeing the Services and other information as reasonably requested by West End Bermuda to facilitate West End Bermuda’s performance of this Agreement. West End Bermuda shall permit Flagstone and its employees and agents reasonable access during regular business hours (or otherwise upon agreement) to individuals responsible for the Services and provide Flagstone with such data and other information as Flagstone may reasonably request for the purposes of allowing Flagstone to monitor the performance of the Services and to assist Flagstone in transitioning the Service functions to Flagstone’s own systems upon the termination of this Agreement, in each case to the extent that such permission or provision does not result in material interruption to West End Bermuda.

(c)           Flagstone and West End Bermuda shall cooperate with and assist one another in obtaining any third party consents or amendments necessary for the performance of the Services hereunder, including, without limitation, any required consent or amendment under any software license; provided, however, that West End Bermuda shall not be required to cooperate with and assist Flagstone in obtaining any consent to amendment where West End Bermuda reasonably

4

concludes (after consultation with Flagstone) that such consent or amendment will result in it incurring out-of-pocket expenses which Flagstone, in its sole discretion, does not approve. Flagstone and West End Bermuda will notify one another promptly after becoming aware that any such consents or amendments are required. Subject to Flagstone’s prior approval, the out-of-pocket costs and expenses of obtaining any such consents or amendments shall be borne by Flagstone. In the event that the parties are unable to obtain any required consent or amendment, they shall negotiate in good faith reasonable modifications of the Services and applicable fees such that such consents or amendments are not required.

8.             Force Majeure. West End Bermuda shall not be liable to Flagstone for delay in performing or failure to perform its obligations under this Agreement if the delay or failure results from events or circumstances outside its reasonable control including, without limitation, fire, flood, explosion, acts of war or hostilities or terrorist activity, riots, government action or inaction, request by any governmental, regulatory or administrative agency, accident or breakage of any machinery or apparatus, strikes or labor disputes or any inability to obtain fuel, power, gas, equipment or transportation, and such delay or failure shall not constitute a breach of this Agreement.
