                        (EFFECTIVE AS OF JANUARY 1, 2002)

1. PURPOSE.

        The purposes of the Plan are to enable the Company and its Subsidiaries
to attract, retain, motivate and reward the best qualified executive officers
and key employees by providing them with the opportunity to earn competitive
compensation directly linked to the Company's performance. The Plan was
originally adopted as January 1, 1996 and has been amended and restated as of
January 1, 2002.

        (b) "Committee" shall mean the Compensation and Organization Committee

3. ADMINISTRATION.

        The Committee shall administer and interpret the Plan, provided that, in
no event, shall the Plan be interpreted in a manner which would cause any award
intended to be qualified as performance based compensation under Section 162(m)
to fail to so qualify. The Committee shall establish the performance objectives
for any calendar year in accordance with Section 4 and certify whether such
performance objectives have been obtained. Any determination made by the
Committee under the Plan shall be final and conclusive. The Committee may employ
such legal counsel, consultants and agents (including counsel or agents who are
employees of the Company or a Subsidiary) as it may deem desirable for the
administration of the Plan and may rely upon any opinion received from any such
counsel or consultant or agent and any computation received from such consultant
or agent. All expenses incurred in the administration of the Plan, including,
without limitation, for the engagement of any counsel, consultant or agent,
shall be paid by the Company. No member or former member of the Board or the
Committee shall be liable for any act, omission, interpretation, construction or
determination made in connection with the Plan other than as a result of such
individual's willful misconduct.

4. BONUSES.

        (a) Performance Criteria. Within 90 days after each Performance Period
begins (or such other date as may be required or permitted under Section
162(m)), the Committee shall establish the performance objective or objectives
that must be satisfied in order for a Participant to receive a bonus and other
long term incentive awards for such Performance Period. Unless the Committee
determines at the time of grant not to qualify the award as performance-based
compensation under Section 162(m), any such performance objectives will be based
upon the relative or comparative achievement of one or more of the following
criteria, as determined by the Committee for the Performance Period: (i)
consolidated earnings before income taxes; (ii) earnings per share; (iii) book
value or adjusted book value per share; (iv) return on shareholders equity; (v)
adjusted gross premium and adjusted direct premium (vi) risk adjusted return on
allocated capital; (vi) the net present value of projected net income after cost
of capital ;(vii) the credit quality and performance of the insured portfolios
of the company's insurance subsidiaries; (viii) the amount of assets under
management of the company's investment management businesses; (ix) the relative
performance of peer group companies; (x) expense management; (xi) return on
investment; (xii) improvements in capital structure; (xiii) profitability of an
identifiable business unit or product.

        (b) Maximum Amount Payable. If the Committee certifies in writing that
any of the performance objectives established for the relevant Performance
Period under Section 4(a) has been satisfied, each Participant who is employed
by the Company or one of its Subsidiaries on the last day of the Performance
Period for which the bonus is payable shall be entitled to receive (i) an annual
bonus in an amount not to exceed $3,000,000 and/or (ii) a long-term award in an
amount not to exceed $5,000,000. If a Participant's employment terminates for
any reason (including, without limitation, his death, disability or retirement
under the terms of any retirement plan maintained by the Company or a
Subsidiary) prior to the last day of the Performance Period for which the bonus
is payable, the maximum bonus payable to such Participant under the preceding
sentence shall be multiplied by a fraction, the numerator of which is the number
of days that have elapsed during the Performance Period in which the termination
occurs prior to and including the date of the Participant's termination of
employment and the denominator of which is the total number of days in the
Performance Period.

<PAGE>

        (c) Negative Discretion. Notwithstanding anything else contained in
Section 4(b) to the contrary, the Committee shall have the right, in its
absolute discretion, (i) to reduce or eliminate the amount otherwise payable to
any Participant under Section 4(b) based on individual performance or any other
factors that the Committee, in its discretion, shall deem appropriate and (ii)
to establish rules or procedures that have the effect of limiting the amount
payable to each Participant to an amount that is less than the maximum amount
otherwise authorized under Section 4(b).

        (d) Affirmative Discretion. Notwithstanding any other provision in the
Plan to the contrary, (i) the Committee shall have the right, in its discretion,
to pay a bonus to any Participant who is not a Covered Employee for the year in
which the amount paid would ordinarily be deductible by the Company for federal
income tax purposes in an amount up to the maximum bonus payable under Section
4(b), based on individual performance or any other criteria that the Committee
deems appropriate and (ii) in connection with the hiring any person who is or
becomes a Covered Employee, the Committee may provide for a minimum bonus amount
in any Performance Period, regardless of whether performance objectives are
attained.

5. PAYMENT.

        Except as otherwise provided hereunder, payment of any bonus amount
determined under Section 4 shall be made to each Participant as soon as
practicable after the Committee certifies that one or more of the applicable
performance objectives have been attained (or, in the case of any bonus payable
under the provisions of Section 4(d), after the Committee determines the amount
of any such bonus).

6. FORM OF PAYMENT.

        The Committee shall determine whether any bonus payable under the Plan
is payable in cash, in shares of Common Stock or in any combination thereof. The
Committee shall have the right to impose whatever conditions it deems
appropriate with respect to the award of shares of Common Stock, including
conditioning the vesting of such shares on the performance of additional
service. The maximum number of shares available for issuance under the Plan
shall be 1,500,000.

7. GENERAL PROVISIONS.

        (a) Effectiveness of the Plan. As amended and restated, the Plan shall
be effective with respect to calendar years beginning on or after January 1,
2002 and ending on or before December 31, 2006, unless the term hereof is
extended by action of the Board.

        (b) Amendment and Termination. Notwithstanding Section 6(a), the Board
or the Committee may at any time amend, suspend, discontinue or terminate the
Plan; provided; however, that no such action shall be effective without approval
by the shareholders of the Company to the extent necessary to continue to
qualify the amounts payable hereunder to Covered Employees as performance-based
compensation under Section 162(m).

        (c) Designation of Beneficiary. Each Participant may designate a
beneficiary or beneficiaries (which beneficiary may be an entity other than a
natural person) to receive any payments which may be made following the
Participant's death. Such designation may be

<PAGE>

changed or canceled at any time without the consent of any such beneficiary. Any
such designation, change or cancellation must be made in a form approved by the
Committee and shall not be effective until received by the Committee. If no
beneficiary has been named, or the designated beneficiary or beneficiaries shall
have predeceased the Participant, the beneficiary shall be the Participant's
spouse or, if no spouse survives the Participant, the Participant's estate. If a
Participant designates more than one beneficiary, the rights of such
beneficiaries shall be payable in equal shares, unless the Participant has
designated otherwise.

        (d) No Right of Continued Employment. Nothing in this Plan shall be
construed as conferring upon any Participant any right to continue in the
employment of the Company or any of its Subsidiaries.

        (e) No Limitation on Corporate Actions. Nothing contained in the Plan
shall be construed to prevent the Company or any Subsidiary from taking any
corporate action which is deemed by it to be appropriate or in its best
interest, whether or not such action would have an adverse effect on any awards
made under the Plan. No employee, beneficiary or other person shall have any
claim against the Company or any Subsidiary as a result of any such action.

        (f) Non-alienation of Benefits. Except as expressly provided herein, no
Participant or beneficiary shall have the power or right to transfer,
anticipate, or otherwise encumber the Participant's interest under the Plan. The
Company's obligations under this Plan are not assignable or transferable except
to (i) a corporation which acquires all or substantially all of the Company's
assets or (ii) any corporation into which the Company may be merged or
consolidated. The provisions of the Plan shall inure to the benefit of each
Participant and the Participant's beneficiaries; heirs, executors,
administrators or successors in interest.

        (g) Withholding. Any amount payable to a Participant or a beneficiary
under this Plan shall be subject to any applicable Federal, state and local
income and employment taxes and any other amounts that the Company or a
Subsidiary is required at law to deduct and withhold from such payment.

        (h) Severability. If any provision of this Plan is held unenforceable,
the remainder of the Plan shall continue in full force and effect without regard
to such unenforceable provision and shall be applied as though the unenforceable
provision were not contained in the Plan.

        (i) Governing Law. The Plan shall be construed in accordance with and
governed by the laws of the State of New York, without reference to the
principles of conflict of laws.

        (j) Headings. Headings are inserted in this Plan for convenience of
reference only and are to be ignored in a construction of the provisions of the
Plan.<PAGE>

                  distributed to the Holders of CPS Securities shall be
                  distributed to the Holders of CPS Securities prior to payment
                  by the Custodial Trust of the Preferred Stock Purchase Price,
                  and shall not be used to purchase shares of Preferred Stock;
                  and (2) the aggregate Liquidation Preference of Preferred
                  Stock purchased from MBIA Insurance shall be reduced by the
                  amount, if any, by which the aggregate face amount of CPS
                  Securities is reduced as a result of losses of principal of or
                  interest on Eligible Assets as required by Section 6.01(g) of
                  the Declaration and Section 6(b) of the General Terms of the
                  CPS Securities attached thereto.

         (d)      MBIA Insurance shall have the right to redeem all or a portion
                  of the Preferred Stock on any Distribution Payment Date upon
                  payment of the Redemption Price for the shares to be redeemed
                  (the "Redemption Proceeds"). Notwithstanding the foregoing,
                  MBIA Insurance shall redeem all of the Preferred Stock if
                  after giving effect to a partial redemption, the aggregate
                  Liquidation Preference of the Preferred Stock outstanding
                  immediately after such partial redemption would be less than
                  $20,000,000. Payment of the Redemption Price will be made on
                  the first Distribution Payment Date after MBIA Insurance
                  properly elects to redeem the Preferred Stock.

         (e)      Notice of any redemption of Preferred Stock shall be mailed to
                  the holders of the Preferred Stock not less than ten (10) days
                  nor more than fifteen (15) days prior to the date fixed for
                  such redemption. At any time before or after a notice of
                  redemption has been given, MBIA Insurance shall deposit the
                  aggregate Redemption Price of the Preferred Stock to be
                  redeemed with any bank or trust company in New York, New York,
                  with directions to pay the holders of the Preferred Stock
                  being redeemed the Redemption Proceeds in exchange for the
                  Preferred Stock.

         (f)      Upon a partial redemption of Preferred Stock held by the
                  Custodial Trust, the Redemption Proceeds shall be allocated
                  pro rata among the Holders of CPS Securities.

         (g)      Upon a complete redemption of all Preferred Stock held by the
                  Custodial Trust prior to a Fixed Rate Distribution Event, the
                  Custodial Trust shall apply the Redemption Proceeds to the
                  purchase of a portfolio of Eligible Assets.

         (h)      For the avoidance of doubt, there is no limitation on the
                  number of times MBIA Insurance may put the Preferred Stock to
                  the Custodial Trust pursuant to and in accordance with the
                  terms of this Agreement.

         (i)      MBIA Insurance may not redeem the Preferred Stock from the
                  holders thereof for a period of two years following a Fixed
                  Rate Distribution Event.

4.       Payments

4.1      On the Preferred Stock Payment Date, after payment of the Put Option
         Premium by MBIA Insurance to the Custodial Trust and payment of the
         distribution amount by the Custodial Trust to the Holders of the CPS
         Securities, in each case for the immediately preceding Distribution
         Period, the Custodial Trust will deliver to MBIA Insurance the proceeds
         attributable to principal received upon the maturity or sale of the
         Custodial Trust's Eligible Assets, net of fees and expenses of the
         Custodial Trust and after any principal is returned to Holders of CPS
         Securities pursuant to Section 6.01(g) of the Declaration and Section
         6(b) of the General Terms of the CPS Securities attached thereto (the
         "Preferred Stock Purchase Price").

4.2      Payment by the Custodial Trust of the Preferred Stock Purchase Price
         shall be made on or prior to 3:00 p.m. on the Preferred Stock Payment
         Date and to the account of MBIA Insurance specified in the Put Notice.

4.3      Payment of the Preferred Stock Purchase Price by the Custodial Trust
         shall be made as provided in Section 4.1 and Section 4.2 without
         setoff, claim, recoupment, deduction or counterclaim; provided,
         however, that if MBIA Insurance exercises its put option under Section
         3 hereof at any time that it has failed to pay all or a portion of the
         Put Option Premium, and such failure has not been cured on or before
         the Preferred Stock Payment Date, the Custodial Trust shall be entitled
         to setoff against the Preferred Stock Purchase Price of such unpaid
         portion of the Put Option Premium.

5.       Put Option Premium

5.1      In consideration for the Custodial Trust's agreement to purchase the
         Preferred Stock in accordance with the terms of this Agreement, MBIA
         Insurance will pay to the Custodial Trust, in US dollars, on each
         Distribution Payment Date during which the put option remains in effect
         and is exercisable as set forth in Section 2.2 hereof, the "Put Option
         Premium," in an amount equal to the product of (A) the Auction Rate on
         the CPS Securities for the respective Distribution Period less the
         excess of (i) the Stated Yield for such Distribution Period over (ii)
         the expenses of the Custodial Trust for such Distribution Period,
         provided that such amount shall be annualized and expressed as an
         annual rate with respect to the face amount of the CPS Securities
         outstanding on the date the Put Option Premium is determined, (B) the
         aggregate face amount of the CPS Securities outstanding at the time the
         Put Option Premium is calculated and (C) a fraction, the numerator of
         which will be the actual number of calendar days in the respective
         Distribution Period, and the denominator of which will be 360 days.

         The Put Option Premium for each Distribution Period will be calculated
         on the Auction Date.

         If as a result of losses of principal of or interest on Eligible Assets
         there is a Delayed Auction, MBIA Insurance will pay to the Custodial
         Trust, in US dollars, on each Distribution Payment Date during which
         the put option remains in effect and is exercisable as set forth in
         Section 2.2 hereof, the "Delayed Put Option Premium," in an amount
         equal to the product of (A) the Delayed Auction Rate on the CPS
         Securities for the Delayed Auction Period less the excess of (i) the
         Stated Yield for such Delayed Auction Period over (ii) the expenses of
         the Custodial Trust for such Delayed Auction Period, provided that such
         amount shall be annualized and expressed as an annual rate with respect
         to the face amount of the CPS Securities outstanding on the date the
         Put Option Premium is determined, (B) the aggregate face amount of the
         CPS Securities outstanding at the time the Delayed Put Option Premium
         is calculated and (C) a fraction, the numerator of which will be the
         actual number of calendar days in the respective Delayed Auction
         Period, and the denominator of which will be 360 days.

         The Delayed Put Option Premium for each Delayed Auction Period will be
         calculated on the Delayed Auction Date.

5.2      The amount of the Put Option Premium shall be calculated by the Trustee
         and delivered in writing (the "Put Option Premium Certificate") to MBIA
         Insurance prior to 5:00 p.m. on each Auction Date. The amount of the
         Delayed Put Option Premium shall be calculated by the Trustee and
         delivered in writing (the "Delayed Put Option Premium Certificate") to
         MBIA Insurance prior to 5:00 p.m. on the Delayed Auction Date. The Put
         Option Premium Certificate, and any Delayed Put Option Premium
         Certificate, also shall set forth the Eligible Assets held by the
         Custodial Trust, the Stated Yield on each Eligible Asset, any fees to
         be incurred or accrued by the Trustee on behalf of the Custodial Trust
         and the computation of the Put Option Premium, or the Delayed Put
         Option Premium, as the case may be, in each case for the respective
         Distribution

         Period and the Delayed Auction Period, respectively, and shall be in
         the form attached hereto as Annex B.

5.3      MBIA Insurance has five (5) days to cure any failure to pay when due
         the Put Option Premium or Delayed Put Option Premium, if any; provided
         that the Put Option Premium during such cure period will be set at the
         Maximum Rate then in effect. 5.4 MBIA Insurance has five (5) days to
         cure any failure to pay when due the Redemption Price; provided that
         the Put Option Premium during such cure period will be set at the
         Maximum Rate then in effect.

6.       Obligations Absolute

6.1      The Custodial Trust acknowledges that, provided MBIA Insurance has
         complied with the terms of this Agreement, the obligations of the
         Custodial Trust undertaken under this Agreement are absolute,
         irrevocable and unconditional irrespective of any circumstances
         whatsoever, including any defense otherwise available to the Custodial
         Trust, in equity or at law, including, without limitation, the defense
         of fraud, any defense based on the failure of MBIA Insurance to
         disclose any matter, whether or not material, to the Custodial Trust or
         any other person, and any defense of breach of warranty or
         misrepresentation, and irrespective of any other circumstance which
         might otherwise constitute a legal or equitable discharge or defense of
         an insurer, surety or guarantor under any and all circumstances. The
         enforceability and effectiveness of this Agreement and the liability of
         the Custodial Trust, and the rights, remedies, powers and privileges of
         MBIA Insurance under this Agreement shall not be affected, limited,
         reduced, discharged or terminated, and the Custodial Trust hereby
         expressly waives, to the fullest extent permitted by applicable law,
         any defense now or in the future arising by reason of:

         (a)      the illegality, invalidity or unenforceability of all or any
                  part of the Declaration; (b) any action taken by MBIA
                  Insurance;

         (d)      any other circumstance whatsoever that might otherwise
                  constitute a legal or equitable discharge or defense of or for
                  the Custodial Trust;

         provided, however, that, notwithstanding the provisions of this Section
         6.1, the Custodial Trust shall have no further obligations under this
         Agreement after the termination of this Agreement. In addition, the
         breach of any covenant made in this Agreement by the Custodial Trust
         shall not terminate this Agreement or limit the rights of MBIA
         Insurance hereunder.

6.2      For the avoidance of doubt, no failure or delay by MBIA Insurance in
         exercising its rights hereunder shall operate as a waiver of its rights
         hereunder (except as specifically provided in this Agreement,
         including, without limitation, in respect of the notice periods and
         payment dates set forth in Section 3.2(a)) and, subject to the

12.      Counterparts

         This Agreement may be executed in any number of counterparts and by the
         different parties hereto on separate counterparts each of which when
         executed and delivered shall constitute an original, but all the
         counterparts shall together constitute but one and the same instrument.

13.      Benefit of Agreement and Disclaimer

13.1     This Agreement shall enure to the benefit of each party hereto and its
         successors and assigns and transferees; provided that neither party
         hereto may transfer its rights and obligations hereunder, by operation
         of law or otherwise, without the prior written consent of the other
         party.

14.      Amendment and Assignment

14.1     This Agreement may not be amended or modified in any respect, nor may
         any provision be waived, without the written agreement of both parties.
         No waiver by one party of any obligation of the other hereunder shall
         be considered a waiver of any other obligation of such party.

14.2     Neither the Custodial Trust nor MBIA Insurance may assign its rights or
         obligations under this Agreement to any other person, except that MBIA
         Insurance may assign its rights and obligations under this Agreement to
         another person as a result of a merger of MBIA Insurance with another
         person or as a result of a sale of all or substantially all of the
         assets of MBIA Insurance to another person if the other person
         expressly assumes all of the rights and obligations of MBIA Insurance
         under this Agreement; and immediately following the merger or sale of
         substantially all of its assets, the rating of the substitute preferred
         stock or the unsecured debt obligations of the other person is at least
         as high as the credit rating of the Preferred Stock or the general
         unsecured debt obligations of MBIA Insurance, as the case may be (or if
         no such ratings exist, the financial strength rating of MBIA Insurance)
         immediately prior to the merger or sale.

15.      Governing Law

15.1     THIS AGREEMENT SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED IN
         ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
         CONFLICTS OF LAW PRINCIPLES.

                                      -14-

16.      Jurisdiction

16.1     Each of the parties hereto irrevocably submits to the non-exclusive
         jurisdiction of the courts of the State of New York in respect of any
         action or proceeding arising out of or in connection with this
         Agreement ("Proceedings"). Each of the parties hereto irrevocably
         waives, to the fullest extent permitted by applicable law, any
         objection that it may now or hereafter have to the laying of the venue
         of any such Proceedings in the courts of the State of New York and any
         claim that any Proceeding brought in any such court has been brought in
         an inconvenient forum. Each of the Custodial Trust and MBIA Insurance
         agrees that it shall at all times have an authorized agent in the State
         of New York upon whom process may be served in connection with any
         Proceedings, and each of the Custodial Trust and MBIA Insurance hereby
         authorizes and appoints the Trustee to accept service of all legal
         process arising out of or connected with this Agreement in the State of
         New York and service on such person (or substitute) shall be deemed to
         be service on the Custodial Trust or MBIA Insurance, as the case may
         be. Except upon such a substitution, the Custodial Trust and MBIA
         Insurance shall not revoke any such authority or appointment and shall
         at all times maintain an agent for service of process in the State of
         New York. If for any reason such person shall cease to act as agent for
         the service of process, the Custodial Trust and MBIA Insurance shall
         promptly appoint another such agent, and shall forthwith notify each
         other of such appointment. The submission to jurisdiction reflected in
         this paragraph shall not (and shall not be construed so as to) limit
         the right of any person to take Proceedings in any court of competent
         jurisdiction, nor shall the taking of Proceedings in any one or more
         jurisdictions preclude the taking of Proceedings in any other
         jurisdiction (whether concurrently or not) if and to the extent
         permitted by law.

17.      Limitation of Liability

17.1     It is expressly understood that (a) this Agreement is executed and
         delivered by The Bank of New York (Delaware), not individually or
         personally but solely as Trustee, in the exercise of the powers and
         authority conferred and vested in it under the Declaration, (b) each of
         the representations, undertakings and agreements herein made on the
         part of the Custodial Trust, is made and intended not as personal
         representations, undertakings and agreements by The Bank of New York
         (Delaware), but is made and intended for the purpose of binding only
         the Custodial Trust, and (c) under no circumstances shall The Bank of
         New York (Delaware) be personally liable for the breach or failure of
         any obligation, representation, warranty or covenant made or undertaken
         by the Custodial Trust, under this Agreement or the other related
         documents.
