2004 Supplemental Executive Retirement Plan

ARTICLE 1.           Purposes of Plan.

1.1                                 Financial Security Assurance Inc. adopted the Financial Security Assurance Inc. Supplemental Executive Retirement Plan (as heretofore amended and restated, the “1989 Plan”), effective January 1, 1989, in order to restore the pension benefits of selected current and future key employees whose benefits under the Financial Security Assurance Inc. Money Purchase Plan are limited by reason of certain limitations imposed by Section 401(a)(17), Section 415 and other provisions of the Internal Revenue Code of 1986, as amended from time to time (the “Code”). Effective as of December 17, 2004, the Company discontinued contributions under the 1989 Plan and established a new supplemental executive retirement plan, serving the same purposes as the 1989 Plan. This new plan, as amended from time to time, is known as the Financial Security Assurance Holdings Ltd. 2004 Supplemental Executive Retirement Plan, and is referred to herein as the “Plan.”  The terms of the Plan govern credits for contributions made commencing January 1, 2006, in respect of limited pension benefits payable in respect of calendar year 2005, and amounts transferred to the Plan from the 1989 Plan as described herein. The Plan is hereby amended and restated effective as of May 18, 2006 to provide that payments due upon a separation from service shall generally not be paid during the six months following the separation from service and to make certain other changes.

(a)             the amount of contribution related to Compensation which would have been payable to or in respect of the Participant under the Basic Plan without regard to the maximum annual pension limitation in Section 415 of the Code or the pensionable compensation limitation in Section 401(a)(17) of the Code or the exclusion of certain deferred amounts, and

(b)            the amount of contribution related to Compensation actually payable to or in respect of the Participant under the Basic Plan.

In addition to the foregoing amounts, the Account of a Participant shall be credited with such amounts in the Participant’s account under the 1989 Plan that are not vested on or before December 31, 2004 and that are deemed transferred to the Plan pursuant to the terms of the 1989 Plan.  Such amounts shall be subject to the terms and conditions of the Plan.

3

4.2                                 Vesting. A Participant shall be 100% vested in his or her Account upon attaining age 55, upon his or her death or Disability while in the employ of a Participating Company or upon the termination of the Plan pursuant to Section 5.2. Except as provided in Section 5.4, if a Participant terminates employment prior to an event specified in the preceding sentence, such Participant shall be vested in his or her Account in accordance with the following schedule:

4.3                                 Crediting of Investment Gain/Loss.

(a)                                  The balance of each Participant’s Account shall be credited with earnings and investment gains and losses as provided below. The Committee may establish procedures permitting Participants to designate one or more investment benchmarks specified by the Chief Executive Officer or the Committee for the purpose of determining the earnings or investment gains and losses to be credited or debited to a Participant’s Account. Investment benchmarks so specified may be made available to all Participants or selected Participants as the Chief Executive Officer or the Committee may designate. The Committee shall have the sole discretion to make such rules as it deems desirable with respect to the administration of any such investment benchmark procedures, including rules permitting the Participant to change the designation of investment benchmarks to be used to measure the value of the Account. The Committee, however, retains the discretion at any time to change the investment benchmarks available to Participants, including any investment benchmarks previously specified by the Chief Executive Officer, or to discontinue the benchmark procedure. If the Committee fails to implement an investment benchmark procedure or discontinues such procedure, or if the Participant fails to designate properly an investment benchmark, the Participant’s Account shall be credited with earnings at a rate determined by the Committee in its sole discretion, utilizing whatever factors or indicia it deems appropriate; provided, however, that the rate of return on a Participant’s Account in such circumstances shall not be less than the Chase Bank prime rate plus one percent.

(b)  Nothing in this Section 4.3 or in the Committee’s rules shall give a Participant the right to require the Company or a Participating Company to acquire any asset for the Account of the Participant, and if the Company or

4

a Participating Company acquires any asset, or causes a trustee on its behalf to acquire any asset, to permit it to satisfy its obligations to pay the balance of the Participant’s Account, the Participant shall have no right or interest in any such asset, which shall be held by the Company or the Participating Company subject to the rights of all unsecured creditors of the Company or the Participating Company. The rights of the Participant with respect to any designation of one or more investment benchmarks for measuring the value of any Account hereunder shall be expressly subject to the provisions of Section 5.6 of the Plan.

4.4                                 Form and Timing of Election.

(a)                                  Except as otherwise provided herein, payment of the Participant’s vested Account balance shall be made as soon as administratively practicable following the Participant’s death, Disability or other separation from service (a “Distribution Event”). Before the taxable year for which the amounts described in Section 4.1 are credited to a Participant’s Account, the Participant may make an election with respect to the timing of the payment of such amounts pursuant to which the Participant may elect a date subsequent to the Participant’s death, Disability or other separation from service on which all or any portion of such amounts shall be distributed. A Participant who becomes eligible to participate in the Plan for the first time after the beginning of a taxable year may make such an election with respect to the timing of the amounts credited to his or her account in such taxable year at any time within thirty days after the date the Participant becomes eligible to participate in the Plan. Notwithstanding the foregoing, amounts that are transferred to the Plan from the 1989 Plan shall be subject to any election with respect to the timing of the payment of such amounts as shall be in effect under the 1989 Plan as of December 31, 2004. A Participant may elect to extend, but not accelerate, a previously elected distribution date at any time at least 12 months before the date of the first scheduled payment by the execution of a SERP Election Change Form, timely filed with the Company, provided that a SERP Election Change Form (i) shall only be effective in respect of amounts that would not otherwise have been distributed during the 12-month period after the filing of such Form; and (ii) must provide for an extension of distribution of at least 5 years from the previously established distribution date to the extent necessary or desirable to comply with the requirements of Section 409A of the Code as interpreted by the Committee in its sole discretion for exclusion from gross income of amounts deferred under the Plan. Notwithstanding the foregoing, effective as of May 18, 2006, any distribution payments due on account of a Participant’s separation from service and otherwise payable during the six-month period following the Participant’s separation from service shall be paid on the first date of the seventh month following the Participant’s separation from service (or, if earlier, the date of death of the Participant).

5

(b)                                         The Participant may elect that his or her vested Account Balance be distributed in a lump sum or in installments payable over a specified number of years, not longer than 15 years; provided, however, that in no event may installment payments be elected over a number of years that is more than the Participant’s life expectancy or the life expectancy of the designated primary Beneficiary, whichever is greater, at the time the Participant elects a form of distribution. If a Participant elects the installment option, the Participant must also elect whether installments should be made annually, quarterly or, if the Committee (or the Chief Executive Officer of the Company in respect of all Participants) shall direct to offer such alternative, monthly. A Participant may specify different payment options (i) for different percentages or dollar amounts of a Participant’s vested Account balance; or (ii) in the event of the death or Disability of the Participant. Distributions will be in the form of a lump sum (i) if the Participant did not choose a different distribution option or (ii) in the event of death or Disability, if the Participant did not expressly choose a different distribution option in the event of death or Disability.

(c)                                          A Participant shall make an election with respect to the form of distribution of amounts credited to his or her Account at the time and in the manner described in Section 4.4(a) for making elections with respect to the timing of the distribution of such amount. An election with respect to the form of distribution of any amounts credited to a Participant’s Account shall be irrevocable. Amounts that are transferred to the Plan from the 1989 Plan shall be subject to any election with respect to the form of distribution of such amounts as shall be in effect under the 1989 Plan as of December 31, 2004.

(d)                                         A form-of-distribution election shall be effective upon submission to the Committee or its designee and compliance with all applicable requirements established by the Committee, provided that the Committee retains the right, at its election, to make payments in a lump sum if it elects, in its sole discretion, to do so notwithstanding any form-of-distribution election requesting an installment option to the extent permitted by Section 409A of the Code as interpreted by the Committee in its sole discretion for exclusion from gross income of amounts deferred under the Plan. Notwithstanding any contrary provision in the Plan, the Committee, in its sole discretion, retains the right, but shall have no obligation, to distribute all or any portion of a Participant’s vested Account balance in the form of any security or other investment chosen by the Participant as an investment benchmark for measuring the value of his or her Account pursuant to Section 4.3(a) of the Plan. Further, notwithstanding any contrary provision in the Plan, any distribution to a Participant otherwise payable hereunder shall be deferred until no later than January 2 in the year following termination of the Participant’s

6

                                                employment with the Company (and its subsidiaries) to the extent that such distribution, if not so deferred, would be disallowed as a tax deduction by the Company pursuant to Section 162(m) of the Code (or any successor provision).

(e)                                  Notwithstanding any other provision of the Plan, any payment required to be made by the Company on a specified date pursuant to the terms of the Plan, or pursuant to any election made under the Plan, may be made as soon thereafter as administratively practicable; provided, however, that such payment will be made no later than the end of the calendar year that includes the specified date or, if later, by the 15th day of the third month following the specified date. Amounts in a Participant’s Account shall continue to be credited with earnings and investment gains and losses pursuant to Section 4.3 until distributed to the extent administratively practicable.

4.5                                 Benefit Restoration With Respect to Certain Bonus Payments. In the event that a Participating Company accelerates the payment of bonuses for any Plan Year by paying bonuses which would otherwise be payable in the following Plan Year, and such payment causes a Participant to be credited with a lower total contribution under the Basic Plan and the Plan by virtue of the limitations provided in the Basic Plan and the limitations on the amount of Compensation provided in Section 2.7 of the Plan, then, notwithstanding any such limitations, the Committee may, in its discretion, credit an additional supplemental pension contribution under the Plan for the Plan Year in which the bonuses were paid on an accelerated basis up to the amount which would otherwise be lost to the Participant by virtue of the application of the limitations in the Basic Plan and in the Plan. The aggregate amounts credited under the Plan, and the contributions actually payable to or in respect of the Participant under the Basic Plan, over a two Plan Year period consisting of the Plan Year into which the bonus was accelerated and the following Plan Year, shall not be increased by virtue of the application of this Section 4.5.

ARTICLE 5.           Administration and General Provisions.

5.1                                 Administration.

(a)                                       The Plan shall be administered by the Committee in accordance with the administrative provisions of the Basic Plan. The Committee shall have full power and authority to interpret, construe and administer the Plan, and review claims for benefits under the Plan, and the Committee’s interpretations and constructions of the Plan and actions thereunder shall be binding and conclusive on all persons and for all purposes.

(b)                                      The Committee shall establish and maintain Plan records and may arrange for the engagement of such certified public accountants, actuarial consultants or legal counsel, and make use of such agents and clerical or other personnel, as they shall require or may deem advisable for purposes of the Plan. The Committee may rely upon the written opinion of such counsel

7

and the consultants or accountants engaged by the Committee and may delegate to any agent or to any sub-committee or member of the Committee its authority to perform any act hereunder, including, without limitation, those matters involving the exercise of discretion, provided that such delegation shall be subject to revocation at any time by the Committee.

(c)                                   To the maximum extent permitted by applicable law, no member of the Committee shall be personally liable by reason of any contract or other instrument executed by him or her in his or her capacity as a member of the Committee, nor for any mistakes of judgment made in good faith, and the Company shall indemnify and hold harmless, directly from its own assets (including the proceeds of any insurance policy the premiums of which are paid from the Company’s own assets), each member of the Committee and each officer, employee or director of the Company to whom any duty or power relating to the administration or interpretation of the Plan or to the engagement or control of the assets of the Plan may be delegated or allocated, against any cost or expense (including counsel fees) or liability including any sum paid in settlement of a claim with the approval of the Company arising out of any act or omission to act in connection with the Plan.

5.2                                 Amendment and Termination. The Plan may be amended, suspended or terminated, in whole or in part, by the Board, but no such action shall retroactively impair or otherwise adversely affect the rights of any person to receive benefits under the Plan which have accrued prior to the date of such action, as determined by the Committee, except to the extent necessary or desirable to comply with the requirements of Section 409A of the Code as interpreted by the Committee in its sole discretion for exclusion from gross income of amounts deferred under the Plan; provided, however, that the amount of any future contribution payable to or in respect of a Participant may be reduced by the amount of any increase in the amount of pension actually payable to the Participant or Beneficiary under the Basic Plan due to any increases in benefits payable under the Basic Plan (whether due to changes in Code Sections 401(a)(17) and 415 limitations or otherwise) subsequent to the Participant’s retirement. Anything in Section 4.4 to the contrary notwithstanding, in the event of the termination of the Plan, the Committee may direct that all Account balances be distributed in the form of a lump sum distribution to the extent permitted by Section 409A of the Code as interpreted by the Committee in its sole discretion for exclusion from gross income of amounts deferred under the Plan.

5.3                                 Company’s Right to Discharge Employees. Nothing contained herein will confer upon any Participant or other employee the right to be retained in the employ of any Participating Company, nor will it interfere with the right of any Participating Company to discharge or otherwise administer the employment and termination of Participants and other employees without regard to the existence of the Plan.

8

5.4                                 Discharge for Cause. Notwithstanding any other provisions contained in the Plan, in the event of a Participant’s Discharge for Cause, such Participant and his or her Beneficiary shall forfeit all rights to any payments under the Plan.

5.5                                 Sale of Company. Nothing in the Plan shall preclude the Company from consolidating with or merging into or with, or transferring all or substantially all its assets to, another corporation which assumes the Plan and all obligations of the Company hereunder. Under such a consolidation, merger, or transfer of assets and assumption, the term “Company” shall refer to such other corporation and the Plan shall continue in full force and effect.

5.6                                 Source of Payments. Participants have the status of general unsecured creditors of the Company and the Plan constitutes a mere promise by the Company to make benefit payments in the future from its general assets; provided, however, that such payments shall be reduced by the amount of any payments made to the Participant or his or her Beneficiary from any trust or special or separate fund established by the Company to assure such payments, and if the Company shall make any investments to aid it in meeting its obligations hereunder, the Participant and his or her Beneficiary shall have no right, title or interest whatever in or to any such investments except as may otherwise be expressly provided in a separate written instrument relating to such investments. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind between the Company and any Participant or Beneficiary. By action of its Board of Directors, any Participating Company may assume joint and several liability with the Company with respect to any obligations under the Plan for Participants employed by the Participating Company.

5.7                                 Withholding. The Company may withhold from any benefits payable under the Plan all Federal, state, city or other taxes as shall be required pursuant to any law or governmental regulation or ruling.

5.8                                 Expenses. All expenses incurred in administering the Plan will be paid by the Company and none will be paid by the Participant.

5.9                                 Assignment. No interest of any Participant or Beneficiary hereunder shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors of the Participant or the Participant’s Beneficiary. The Plan shall be binding upon and inure to the benefit of the Company and its successors and assigns and the Participant, his or her Beneficiary and estate. Notwithstanding the foregoing, pursuant to rules comparable to those applicable to qualified domestic relations orders, as determined by the Committee, the Committee may direct a distribution prior to any distribution date otherwise described in the Plan, to an alternate payee (as defined under the rules applicable to qualified domestic relations orders) to the extent permitted by Section 409A of the Code as interpreted by the Committee in its sole discretion for exclusion from gross income of amounts deferred under the Plan.

5.10                           ERISA Status of Plan. The Plan is intended to constitute an “unfunded plan for management or other highly compensated individuals” as defined in the Employee

9

                                                Retirement Income Security Act of 1974, as amended from time to time (“ERISA”), and is subject to certain provisions of ERISA, including certain requirements relating to reporting, disclosure, enforcement and claims.

5.11                           Applicable Law. The Plan shall be construed, regulated and administered according to ERISA (to the extent applicable), the Code and the laws of the State of New York.
