The SCA Parties and the CDS Counterparties hereby agree to negotiate in good faith in an effort to reach an agreement on the appropriate treatment of such public finance business in

-36-

connection with the CDS Counterparty Restructuring (it being understood that failure to reach such agreement, notwithstanding good faith negotiations, shall not constitute a default hereunder or give rise to any cause of action against any Party hereto). Without the consent of CDS Counterparties representing the Minimum Consenting CDS Counterparty Restructuring Threshold, the SCA Parties shall not transfer or otherwise dispose of such public finance business prior to October 15, 2008, except for reinsurance cessions for risk management purposes not intended to effectuate a transfer of the business in whole or any substantial part or to the extent it is agreed between the NYID and the SCA Parties that to transfer such public finance business is necessary and/or in the public interest (as to which the CDS Counterparties reserve all rights to challenge or object).

                    Section 6.17 Disclosure Schedules; Supplementation and Amendment of Schedules. The SCA Parties may, at their option, include in the Schedules items that are not material in order to avoid any misunderstanding, and such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgement or representation that such items are material, to establish any standard of materiality or to define further the meaning of such terms for purposes of this Agreement. Information disclosed in the Schedules shall constitute a disclosure for all purposes under this Agreement notwithstanding any reference to a specific section, and all such information shall be deemed to qualify the entire Agreement and not just such section. From time to time, prior to the Closing, the SCA Parties shall have the right to supplement or amend the Schedules with respect to any matter arising hereafter or discovered after the delivery of the Schedules pursuant to this Agreement. No such supplement or amendment shall have any effect on the satisfaction of the condition to closing set forth in Section 7.01(a); provided, however, if the Closing shall occur, then the Parties (other than the SCA Parties) shall be deemed to have waived any right or claim pursuant to the terms of this Agreement or otherwise, including pursuant to Section 9.11 hereof, with respect to any and all matters disclosed pursuant to any such supplement or amendment prior to the Closing.

                    Section 9.06 Assignment. This Agreement may not be assigned by operation of Law or otherwise without the express written consent of all Parties (which consent may be granted or withheld in the sole discretion of each of the Parties) and any such assignment or attempted assignment without such consent shall be void.

                    Section 9.07 Amendment. This Agreement may not be amended, altered, supplemented or modified except (a) by an instrument in writing signed by, or on behalf of, all Parties, or (b) by a waiver in accordance with Section 9.08; provided, that, notwithstanding anything to the contrary in this Section 9.07 or in Section 9.08 below, the following sections and definitions set forth in this Agreement may not be amended, altered, supplemented, modified or waived without the unanimous consent of the CDS Counterparties: the definitions of “XLFA Redomestication,” “Minimum Consenting CDS Counterparty Restructuring Threshold” and “Required Consenting CDS Counterparties,” and Sections 2.05, 2.06, 2.07(b), 2.10, 6.03, 6.04, 6.05, 6.06, 6.07, 6.10(b), 6.10(d), 6.12, 6.13, 6.14, 6.16, 6.18, 6.20, 6.21, 6.23, 9.07 and 9.08.

                    Section 9.08 Waiver. Subject to the provisions in Section 9.07 above, which provide that, notwithstanding anything to the contrary in Section 9.07 or this Section 9.08, the following sections and definitions set forth in this Agreement may not be amended, altered, supplemented, modified or waived without the unanimous consent of the CDS Counterparties: the definitions of “XLFA Redomestication,” “Minimum Consenting CDS Counterparty Restructuring Threshold” and “Required Consenting CDS Counterparties,” and Sections 2.05, 2.06, 2.07(b), 2.10, 6.03, 6.04, 6.05, 6.06, 6.07, 6.10(b), 6.10(d), 6.12, 6.13, 6.14, 6.16, 6.18, 6.20, 6.21, 6.23, 9.07 and 9.08, the SCA Parties, acting unanimously as a group, and the XL Parties, acting unanimously as a group, may (a) extend the time for the performance of any of the obligations that one or more members of another group owes to one or more of its members, (b) waive any right that one or more of its members may have due to inaccuracies in the representations and warranties made by any member of another group or contained in any Transaction Document or (c) waive compliance with any of the agreements of any member of another group, solely as they relate to the members of such waiving group, or conditions to the obligations of the members of such waiving group contained herein. Any such extension, waiver

-46-

or amendment shall be valid only if set forth in an instrument in writing signed by all of the SCA Parties and XL Parties to be bound thereby. Any such extension, waiver or amendment will promptly be provided to all CDS Counterparties in writing and, if any CDS Counterparty objects to such extension, waiver or amendment, such CDS Counterparty will have five (5) Business Days from receipt of such extension, waiver or amendment to provide written notice to all other Parties that it intends to withdraw from this Agreement. If such CDS Counterparty provides such timely notice, it will be deemed to have withdrawn as a Party to this Agreement on the date that such waiver, extension or amendment becomes effective and the terms hereof shall have no further force or effect with regard to such CDS Counterparty; provided, that (i) any release made by any CDS Counterparty withdrawing as a party to this Agreement pursuant to this Section 9.08 and any release made by any SCA Party or any XL Party with respect to such withdrawing CDS Counterparty, in each case to the extent such releases shall have become effective prior to the time of such withdrawal, shall in each case remain in full force and effect after such withdrawal, and (ii) following such withdrawal, subject to the preceding clause (i), such withdrawing CDS Counterparty shall cease to have any other obligations or rights hereunder or in connection with the Transactions (including under Sections 2.05(c) and 6.10(b)), and after such withdrawal, such CDS Counterparty will no longer be deemed to be a “CDS Counterparty” for purposes of this Agreement or any Ancillary Agreement. If the CDS Counterparty does not provide such timely notice, it shall be deemed to have approved the waiver, extension or amendment. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition or as a waiver of any other term or condition of this Agreement. The failure of any Party hereto to assert any of its rights hereunder shall not constitute a waiver of any other rights. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

                    Section 9.09 No Third-Party Beneficiaries. This Agreement shall be binding upon and inure solely to the benefit of the Parties and, except as provided in Section 2.05, their respective successors and permitted assigns, and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit, remedy or right of action of any nature whatsoever, arising directly or indirectly out of, based upon, or in any way related to or in connection with this Agreement or the Ancillary Agreements.

                    Section 9.10 Rights and Remedies. Each Party acknowledges and agrees that each Party would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that any material breach of this Agreement by another Party could not be adequately compensated by monetary damages alone. Accordingly, in addition to any other right or remedy to which such Party may be entitled, at Law or in equity, it shall be entitled to enforce any provision of this Agreement by a decree of specific performance and to temporary, preliminary and permanent injunctive relief to prevent breaches or threatened breaches of any of the provisions of this Agreement, without posting any bond or other undertaking. For the avoidance of doubt, any liability of any CDS Counterparty that may arise in connection with this Agreement shall neither be joint nor joint and several with any other CDS Counterparty.

                    Section 9.11 Indemnification. (a) The XL Parties shall jointly and severally indemnify and hold harmless each of the SCA Parties, and their respective Subsidiaries, Affiliates, officers, directors, employees, agents, successors and permitted assigns (collectively,

-47-

“SCA Indemnitees”), for and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties (including attorneys’ and consultants’ fees and expenses) actually suffered or incurred (including any action, claim, suit or other proceeding brought or otherwise initiated by any of them) (“Losses”) by any such SCA Indemnitee arising out of or resulting from the breach of any provision of this Agreement prior to Closing by any of the XL Parties.

                    (b) The SCA Parties shall jointly and severally indemnify and hold harmless each of the XL Parties, and their respective Subsidiaries, Affiliates, officers, directors, employees, agents, successors and permitted assigns (collectively, “XL Indemnitees”), for and against any and all Losses incurred by any such XL Indemnitee arising out of or resulting from (i) the breach of any provision of this Agreement prior to Closing by any of the SCA Parties or (ii) any action taken pursuant to the written direction of the SCA Parties under Section 6.22 or prohibited to be taken pursuant to Section 6.22.

                    Section 9.12 No Survival. None of the representations and warranties other than those contained in Sections 3.01 (other than as to enforceability for reasons other than fraud, ultra xxxxx action, improper authorization, or failure to be duly organized, validly existing or in good standing in any applicable jurisdiction), 3.02, 3.03, 4.01, 4.02, 4.03, 4.04, 4.05, 5.01, 5.02 and 5.03 shall survive the Closing. The representations and warranties contained in Sections 3.01 (other than as to enforceability for reasons other than fraud, ultra xxxxx action, improper authorization, or failure to be duly organized, validly existing or in good standing in any applicable jurisdiction), 3.02, 3.03, 4.01, 4.02, 4.03, 4.04, 4.05, 5.01, 5.02 and 5.03 shall survive for the statute of limitations for contracts of the nature of this Agreement.

                    Section 9.13 Several Liability of the CDS Counterparties. For the avoidance of doubt, the obligations of the CDS Counterparties under this Agreement shall be several and not joint and several.

                    Section 9.14 Governing Law and Jurisdiction. This Agreement shall be interpreted under and governed by the Laws of the State of New York without giving effect to conflicts of law provisions thereof. In the event that there is a dispute between or among the Parties arising under this Agreement, other than with respect to events arising under the 2001 Facultative Quota Share Commutation Agreement or the Excess of Loss Commutation Agreement, the Parties (i) agree that the exclusive forum to seek remedy shall be to institute a legal proceeding in the courts of the State of New York located in the City and County of New York, (ii) hereby expressly submit to the personal jurisdiction and venue of such courts for the purposes thereof and expressly waive any claim of lack of personal jurisdiction and improper venue and any claim that such courts are an inconvenient forum and (iii) agree that the prevailing Parties shall be entitled to recover their reasonable attorneys’ fees, costs and disbursements from the other Parties (in addition to any other relief to which the prevailing Parties may be entitled). Each Party hereby irrevocably consents to the service of process of any of the aforementioned courts in any such suit, action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the address provided to the Parties in accordance with Section 9.02, such service to become effective ten (10) days after such mailing.

-48-

                    Section 9.15 Waiver of Jury Trial. Each of the Parties hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under, or in connection with this Agreement or the Transactions. Each of the Parties hereby (i) certifies that no representative, agent or attorney of any other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (ii) acknowledges that it has been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.15.

                    Section 9.16 Fully Negotiated Agreement. Each Party has had the opportunity to negotiate the terms, consult with counsel, and modify the provisions of this Agreement and the Ancillary Agreements. Therefore, the terms of this Agreement and the Ancillary Agreements shall be considered and interpreted without any presumption, inference or rule requiring construction or interpretation of any provision of this Agreement against the interests of the drafter of the Agreement.

                    Section 9.17 Currency. Unless otherwise specified in this Agreement, all references to currency, monetary values and dollars set forth herein shall mean United States (U.S.) Dollars and all payments hereunder shall be made in United States Dollars.

                    Section 9.18 Counterparts. This Agreement may be executed and delivered in multiple counterparts, each of which, when so executed and delivered, shall be an original, but such counterparts shall together constitute but one and the same instrument and agreement.
