                   FACULTATIVE QUOTA SHARE REINSURANCE TREATY
                   ------------------------------------------

            This Facultative Quota Share Reinsurance Agreement is between
X.L. Financial Assurance Ltd., a Bermuda corporation (herein referred to
as the "Ceding Company"), and XL Insurance Ltd, a Bermuda company (herein
referred to as the "Reinsurer").

            WITNESSETH, in consideration of the mutual covenants of this
Facultative Quota Share Reinsurance Agreement, the parties agree as follows:

                                   ARTICLE I
                                   ---------

                  BUSINESS COVERED; REPRESENTATION OF REINSURER
                  ---------------------------------------------

            1.1 The Ceding Company agrees to cede and the Reinsurer agrees to
accept, under the terms of this Facultative Quota Share Reinsurance Agreement,
Policies hereafter issued on behalf of the Ceding Company. Cessions accepted by
the Reinsurer hereunder shall be effected by way of quota share reinsurance
(unless otherwise agreed by the parties), whereby the Reinsurer shall accept and
reinsure as the parties may mutually agree Net Liabilities in respect of each
Policy accepted pursuant to the terms of this Facultative Quota Share
Reinsurance Agreement.

            1.2 Such cessions shall apply to all Policies which have been
submitted to and accepted by Reinsurer in accordance with the provisions of
Article II hereof.

                                   ----------

                       ACCEPTANCE OF FACULTATIVE CESSIONS
                       ----------------------------------

            1.3 Ceding Company shall submit all cessions to the Reinsurer for
acceptance hereunder. All such submissions shall contain such information about
the Policy to be reinsured as the Reinsurer may reasonably require.

            1.4 The Reinsurer shall have the right, in its sole discretion, to
accept or reject any cession presented to the Reinsurer by the Ceding Company
pursuant to a reinsurance memorandum in substantially the same form of Exhibit A
annexed to this Facultative Quota Share Reinsurance Agreement (the "Reinsurance
Memorandum"). The Reinsurer shall not be bound hereunder on any individual
cession unless it first has given its approval by providing the Ceding Company
with a copy of the Reinsurance Memorandum for that particular risk signed by a
duly authorized representative of the Reinsurer. The Reinsurer shall either
return the signed Reinsurance Memorandum or notify the Ceding Company in writing
of its decision not to accept a particular cession as soon as practicable.

            1.5 Once the Reinsurer has provided the Ceding Company with such
signed Reinsurance Memorandum, the Reinsurer shall be bound to provide coverage
under this Facultative Quota Share Reinsurance Agreement in accordance with the
terms and conditions of the underlying Policy, unless the terms and conditions
of coverage with respect to the particular risk relating to such Policy are
modified in the Reinsurance Memorandum pertaining to that risk. The Reinsurer's
Net Liabilities in respect of each such Policy shall attach as of the effective
date of the Policy, unless the Reinsurance Memorandum provides for a different
date. Unless otherwise provided by the Reinsurance Memorandum, the Reinsurer
shall assume the designated por-

                                      -2-

tion or amount of principal or other obligation insured under the Policy, any
interest or premium on such amount assumed and a pro rata share of Loss Expenses
Paid.

            1.6 The share of the Reinsurer in the interests and liabilities of
the Policies covered by this Facultative Quota Share Reinsurance Agreement shall
be separate and apart from the shares of any other reinsurers assuming such
risks. The Reinsurer's obligation pursuant to this Facultative Quota Share
Agreement shall not be joint with any such other reinsurer and in no event shall
the Reinsurer participate in the interests and liabilities of such other
reinsurers.

            1.7 Notwithstanding the provisions of Sections 2.2 and 2.3 hereof to
the contrary, the Ceding Company and the Reinsurer may agree to substitute
mutually acceptable underwriting criteria and standards for the procedures set
forth in Sections 2.1 and 2.2.

            1.9 Should one party at any time:

                  (1)   become insolvent, or

                  (2)   file a petition in bankruptcy, or

                  (3)   be the subject of liquidation or rehabilitation
                        proceeding, or

                  (4)   have a receiver appointed, or

                  (5)   be acquired or controlled by any other insurance company
                        or organization,

the other party shall have the right to terminate this Facultative Quota Share
Reinsurance Agreement forthwith by giving notice in writing to the first party.

            1.10 In the event of the termination of this Facultative Quota Share
Reinsurance Agreement, Reinsurer shall continue to be liable for Net Liabilities
in respect of Policies in force which have been accepted pursuant to the terms
of Article II hereof and with respect to which notice of occurrence, claim or
circumstances which may give rise to a claim is given by the insured to the
Ceding Company prior to natural expiration or termination or anniversary date of
such Policies ceded to the Reinsurer under this Facultative Quota Share
Reinsurance Agreement.

calculating the amount of Loss hereunder, only Loss in respect of that portion
of any insurance or reinsurance which the Ceding Company retains net of third
party reinsurance for its own account shall be included.

            1.11 The amount of the Reinsurer`s liability hereunder in respect of
any Loss shall not be increased by reason of the inability of the Ceding Company
to collect from any other reinsurers, whether specific or general, any amounts
which may have became due from them, whether such inability arises from the
insolvency of such other reinsurers or otherwise.

            1.12 It is understood and agreed that recoveries by the Ceding
Company from other reinsurance (except catastrophe excess reinsurance which
shall inure to the benefit of the Reinsurer) shall be entirely disregarded for
all purposes of this Facultative Quota Share Reinsurance Agreement and shall
inure to the sole benefit of the Ceding Company.

Premiums Written, unless otherwise specified in a Reinsurance Memorandum.

time to time, the right to offset any balances, whether on account of premiums
or on account of losses or otherwise, due from such party to the other party

the party asserting the right of offset shall have and may exercise such right
whether the balance or balances due or to become due to such party from the
other are on account of premiums or on account of losses or otherwise and
regardless of the capacity, whether as Ceding Company or as Reinsurer, in which
each party acted under the agreement or, if more than one, the different
agreements involved.

            IX.1 The Ceding Company, in its discretion, shall adjust,
investigate, settle, defend or compromise all claim and losses. All costs and
expenses incurred in connection therewith, excepting overhead expenses of the
Ceding Company, shall be borne by the Ceding Company and the Reinsurer as Loss
Expenses Paid in proportion to their respective Net Liabilities hereunder and
shall include outside legal, loss accounting, loss auditing or other services
not a part of the ordinary servicing function provided by the Ceding Company,
but shall not include (i) salaries or expenses of persons employed by the Ceding
Company in an administrative or supervisory capacity, or (ii) ordinary office

            Inadvertent delays, errors or omissions made in connection with this
Facultative Quota Share Reinsurance Agreement or any transaction hereunder shall
not relieve either party from any liability which would have attached had such
delay, error or omission not occurred, provided always that such error or
omission is rectified as soon as possible after discovery, and provided that the
party making such error or omission or responsible for such delay shall be
responsible for any additional liability which attaches as a result.

interpretations, assessments, waivers, the exact proportion of premiums paid to
the Ceding Company without any deductions for brokerage, and to the same
modifications, alterations and cancellations, as the respective Policies of the
Ceding Company to which such reinsurance relates, the true intent of this
Facultative Quota Share Reinsurance Agreement being that the Reinsurer shall, in
every case to which this Facultative Quota Share Reinsurance Agreement applies
and in the proportion specified herein, follow the fortunes of the Ceding
Company, and the Reinsurer shall be bound, without limitation, by all payments
and settlements entered into by the Ceding Company in good faith.

                                   ARBITRATION
                                   -----------

            XIV.1 Any dispute or other matter in question arising between the
parties out of or relating to the interpretation, performance, or breach of this
Facultative Quota Share Reinsurance Agreement, whether such dispute arises
before or after termination of this Facultative Quota Share Reinsurance
Agreement shall be settled by arbitration under The Arbitration Act 1986 or any
re-enactment or statutory modification thereof. Arbitration shall be initiated
by the delivery of a written notice of demand for arbitration by one party to
the other within a reasonable time after the dispute has arisen.

            1.18 Each party shall appoint an individual as arbitrator, and the
two so appointed shall then appoint a third arbitrator. If either party refuses
or neglects to appoint an arbitrator within sixty days, the other party may
appoint the second arbitrator. If the two arbitrators do not agree on a third
arbitrator within sixty days of their appointment, each of the arbitrators shall
nominate three individuals. Each arbitrator shall then decline two of the
nominations presented by the other arbitrator. The third arbitrator shall then
be chosen from the remaining two nominations by drawing lots. The arbitrators
shall be active or retired officers of insurance or reinsurance companies; the
arbitrators shall not have personal or financial interest in the result of the
arbitration.

<PAGE>

            1.19 The arbitration hearings shall be held in Hamilton, Bermuda.
Each party shall submit its case to the arbitrators within a reasonable time
after the selection of the third arbitrator or as may be agreed by the
arbitrators. The arbitrators shall not be obliged to follow the rules of the
evidence except to the extent required by governing law; they shall make their
decisions according to the practice of the reinsurance business. The decision
rendered by a majority of the arbitrators shall be final and binding on both
parties. Such decision shall be a condition precedent to any right of legal
action arising out of the arbitrated dispute which either party may have against
the other. Judgment upon the award rendered may be entered in any court having
jurisdiction thereof.

            1.20 Each party shall pay the fee and expenses of its own arbitrator
and one-half of the fee and expenses of the third arbitrator. All other expenses
of the arbitration shall be equally divided between the parties.

                                  -------------

            This Facultative Quota Share Reinsurance Agreement shall be governed
by and construed in accordance with the internal laws of Bermuda, without giving
effect to the principles of conflicts of laws thereof.

                                  ARTICLE XVI

                                   ----------

            XVI.1 In the event of the insolvency of the Ceding Company and the
appointment of a liquidator, receiver, conservator or statutory successor, this
reinsurance shall be pay-

                                      -11-
<PAGE>

able immediately upon demand, with reasonable provision for verification, on the
basis of the liability of the Ceding Company as a result of claims allowed
against the Ceding Company by any court of competent jurisdiction or any
liquidator, receiver, conservator or statutory successor having authority to
allow such claims, without diminution because of such insolvency or because such
liquidator, receiver, conservator, or statutory successor has failed to pay all
or a portion of any claims.

            1.21 Payments by the Reinsurer as above set forth shall be made
directly to the Ceding Company or to its liquidator, receiver, conservator or
statutory successor, except (a) where this contract specifies another payee in
the event of the insolvency of the Ceding Company, and (b) the Reinsurer with
the consent of the direct insureds have assumed such policy obligations of the
Ceding Company as their direct obligations to the payees under such Policies, in
substitution for the obligations of the Ceding Company to such payees.

            1.22 In the event of the insolvency of the Ceding Company, the
liquidator, receiver, conservator or statutory successor of the Ceding Company
shall give written notice to the Reinsurer of the pendency of a claim against
the insolvent Ceding Company on the Policy or Policies reinsured within as
reasonable time after such claim is filed in the insolvency proceeding and
during the pendency of such claim the Reinsurer may investigate such claim and
interpose, at its own expense, in the proceeding where such claim is to be
adjudicated any defense or defenses which it may deem available to the Ceding
Company or its liquidator, receiver, conservator or statutory successor. The
expense thus incurred by the Reinsurer shall be chargeable subject to court
approval against the insolvent Ceding Company as part of the expense of
liquidation to the extent of a proportionate share of the benefit which may
accrue to the Ceding Company solely as a result of the defense undertaken by the
Reinsurer.

        AMENDMENT NO. 1 TO FACULTATIVE QUOTA SHARE REINSURANCE AGREEMENT

                AMENDMENT NO. 1 dated as of [ ] by and between XL FINANCIAL
ASSURANCE LTD., a company incorporated under the laws of Bermuda (hereinafter
referred to as "Ceding Company") and XL INSURANCE (BERMUDA) LTD, a company
incorporated under the laws of Bermuda, (hereinafter referred to as
"Reinsurer").

                WHEREAS, the Ceding Company and the Reinsurer entered into a
facultative quota share reinsurance agreement effective August 17, 2001
("Facultative Agreement") attached hereto as Exhibit A pursuant to which the
Reinsurer agreed to cede to the Reinsurer, on a quota share basis, risk in
respect of Policies issued by the Ceding Company which cessions the Reinsurer
may accept or reject in its sole discretion;

                WHEREAS, the Ceding Company and the Reinsurer wish to amend the
Facultative Agreement to amend the terms of Article IV of the Facultative
Agreement provisions.

                Section 1. DEFINITIONS. Except as otherwise defined in this
Amendment No. 1, terms defined in the Facultative Agreement are used herein as
defined therein.

                Section 2. AMENDMENTS. The Facultative Agreement is hereby
amended as follows:

                2.01.   References in the Facultative Agreement (including
        references to the Facultative Agreement as amended hereby) to "this
        Agreement" (and indirect references such as "hereunder", "hereby",
        "herein" and "hereof") shall be deemed to be references to the
        Facultative Agreement as amended hereby.

                2.02.   Section 1.9 of Article IV is amended to add the
        following provisions at the end of said section:

        "Further, the Reinsurer shall have the right to terminate this
        Facultative Quota Share Reinsurance Agreement at any time upon not less
        than days prior written or electronic notice to the Ceding Company upon
        the occurrence of either one or the following events:

        (i)     a "Ceding Company Change in Control" (as defined below) and,

        (ii)    a downgrade of the Ceding Company's Standard & Poor's financial
        strength rating below AA or a downgrade of the Ceding Company's Moody's
        financial strength rating below Aa2.

For the purposes of this Facultative Quota Share Reinsurance Agreement, a
"Ceding Company Change in Control" will be deemed to occur in the event that (i)
the ownership in Security Capital Assurance Ltd ("SCA") by the Reinsurer or by
the Reinsurer and its affiliates, falls below

<PAGE>

thirty five percent (35%) or (ii) SCA's direct or indirect ownership interest in
the issued and outstanding shares of voting securities of the Ceding Company
falls below ninety five (95%)."

                Section 3. CONDITIONS PRECEDENT. The amendment to the
Facultative Agreement set forth in Section 2 above shall become effective, as of
the date hereof, upon the satisfaction of the following condition precedent:

                3.01. EXECUTION. This Amendment No. 1 shall have been executed
        and delivered by each of the Ceding Company and the Reinsurer.

                Section 4. MISCELLANEOUS. Except as herein provided, the
Facultative Agreement shall remain unchanged and in full force and effect. This
Amendment No. 1 may be executed in any number of counterparts, all of which
taken together shall constitute one and the same amendatory instrument and any
of the parties hereto may execute this Amendment No. 1 by signing any such
counterpart. This Amendment No. 1 shall be governed by, and construed in
accordance with, the laws of Bermuda.
