ARTICLE 23 - FUNDING OF RESERVES

(This Article applies to the Reinsurer who does not qualify for credit by any
state or any other governmental authority having jurisdiction over the Company's
loss reserves and/or to the Reinsurer to which the provisions of the Contingent
Collateral Article apply.)

A.    As regards policies issued by the Company coming within the scope of this
      Agreement, the Company agrees that when it shall file with the insurance
      regulatory authority or set up on its books reserves for unearned premium
      and losses covered hereunder which it shall be required by law to set up,
      it shall forward to the Reinsurer a statement showing the proportion of
      such reserves which is applicable to the Reinsurer. The Reinsurer hereby
      agrees to fund such reserves in respect of unearned premium, known
      outstanding losses that have been reported to the Reinsurer and loss
      expense relating thereto, losses and loss expenses paid by the Company but
      not recovered from the Reinsurer, plus reserves for losses and loss
      expenses incurred but not reported, as shown in the statement prepared by
      the Company (hereinafter referred to as "Reinsurer's Obligations") by cash
      advances, Trust Agreement or a Letter of Credit. The Reinsurer shall have
      the option of determining the method of funding provided it is acceptable
      to the insurance regulatory authorities having jurisdiction over the
      Company's reserves and provided that the issuing bank is approved by the
      NAIC Securities Valuation Office.

B.    When funding by a Letter of Credit, the Reinsurer agrees to apply for and
      secure timely delivery to the Company of a clean, irrevocable and
      unconditional Letter of Credit issued by a bank consented to by the
      Company with such consent not being unreasonably withheld, and containing
      provisions acceptable to the insurance regulatory authorities having
      jurisdiction over the Company's reserves in an amount equal to the
      Reinsurer's Obligations. Such Letter of Credit shall be issued for a
      period of not less than one year, and shall be automatically extended for
      one year from its date of expiration or any future expiration date unless
      60 calendar days (90 calendar days where required by insurance regulatory
      authorities) prior to any expiration date the issuing bank shall notify
      the Company by certified or registered mail that the issuing bank elects
      not to consider the Letter of Credit extended for any additional period.

C.    The Reinsurer and Company agree that the Letters of Credit, or other
      method of funding, provided by the Reinsurer pursuant to the provisions of
      this Article may be drawn upon at any time, notwithstanding any other
      provision of this Agreement, and be utilized by the Company or any
      successor, by operation of law, of the Company including, without
      limitation, any liquidator, rehabilitator, receiver or conservator of the
      Company for the following purposes:

      1.    to reimburse the Company for the Reinsurer's Obligations, the
            payment of which is due under the terms of this Agreement and which
            has not been otherwise paid;

Surety Quota Share Treaty
Effective: January 1, 2005
Page 9 of 15 (Revised - 5/10/05)

<PAGE>

      2.    to make refund of any sum which is in excess of the actual amount
            required to pay the Reinsurer's Obligations under this Agreement;

      3.    to fund an account with the Company for the Reinsurer's Obligations.
            Such cash deposit shall be held in an interest bearing account
            separate from the Company's other assets, and interest thereon not
            in excess of the prime rate shall accrue to the benefit of the
            Reinsurer;

      4.    to pay the Reinsurer's share of any other amounts the Company claims
            are due under this Agreement.

D.    In the event the amount drawn by the Company on any Letter of Credit, or
      other method of funding, is in excess of the actual amount required for in
      Paragraphs C.1. or C.3. above, or in the case of Paragraph C.4. above, the
      actual amount determined to be due, the Company shall promptly return to
      the Reinsurer the excess amount so drawn. All of the foregoing shall be
      applied without diminution because of insolvency on the part of the
      Company or the Reinsurer.

E.    The issuing bank shall have no responsibility whatsoever in connection
      with the propriety of withdrawals made by the Company or the disposition
      of funds withdrawn, except to ensure that withdrawals are made only upon
      the order of properly authorized representatives of the Company.

F.    At quarterly intervals, or less frequently as agreed but never less
      frequently than annually, the Company shall prepare a specific statement
      of the Reinsurer's Obligations, for the sole purpose of amending the
      Letter of Credit or other method of funding, in the following manner:

      1.    If the statement shows that the Reinsurer's Obligations exceed the
            balance of the Letter of Credit as of the statement date, the
            Reinsurer shall, within 15 calendar days after receipt of notice of
            such excess, secure delivery to the Company of an amendment to the
            Letter of Credit increasing the amount of credit by the amount of
            such difference. Should another method of funding be used, the
            Reinsurer shall, within the time period outlined above, increase
            such funding by the amount of such difference.

      2.    If, however, the statement shows that the Reinsurer's Obligations
            are less than the balance of the Letter of Credit as of the
            statement date, the Company shall, within 15 calendar days after
            receipt of written request from the Reinsurer, release such excess
            credit by agreeing to secure an amendment to the Letter of Credit
            reducing the amount of credit available by the amount of such excess
            credit. Should another method of funding be used, the Company shall,
            within the time period outlined above, decrease such funding by the
            amount of such excess.

      3.    If the Reinsurer does not agree with the statement of the
            Reinsurer's Obligations as furnished by the Company, a mutually
            agreed upon independent national actuarial firm shall be engaged to
            evaluate the Reinsurer's Obligations covered under this Agreement
            and such evaluation shall be binding upon the parties hereof. Such
            cost shall be shared equally between the Company and the Reinsurer.
            If the parties fail to agree on the selection of an independent
            national actuarial firm, each of the parties shall name two, of whom
            the other shall decline one, and the final decision shall be made by
            drawing lots.

Agreement.)

(This Article shall not apply to Lloyd's Syndicates who have satisfied their

Reinsurer:

1.    has been assigned an A.M. Best's insurer financial strength rating below
      "A-" or a Standard & Poor's insurer financial strength rating below "A-"

<PAGE>

b.    reserves for loss and loss expense reported and outstanding;

c.    reserves for loss and loss expense incurred but not reported; and

d.    if applicable, unearned premium.

Such Reinsurer's Collateral shall be established by the Reinsurer within ten
business days of receipt by the Reinsurer of the Company's written notice
requesting the establishment of such Reinsurer's Collateral, and the notice
shall be sent by the Company, to the Reinsurer, via certified mail or
internationally recognized overnight courier service. The Reinsurer's Collateral
shall be established and maintained in accordance with the provisions of the
Funding of Reserves Article stated in this Agreement. If a Trust Agreement is
established, the Reinsurer shall select the trustee bank with the consent of the
Company, with such consent not to be unreasonably withheld.

If the Reinsurer does not agree with the statement of the Reinsurer's Collateral
as furnished by the Company, a mutually agreed upon independent national
actuarial firm shall be engaged to evaluate the Reinsurer's Collateral and such

the calculation and the employee of same engaged to evaluate the Reinsurer's
Collateral hereunder shall not be under the influence of either party hereto and
shall be a Fellow of the Casualty Actuarial Society. It is agreed by the parties
hereto that the Arbitration Article of this Agreement shall not apply to the
resolution of disputes arising under the terms of this paragraph. The evaluation
by the independent national actuarial firm shall be binding on the Company and
the Reinsurer.

The Reinsurer shall bear all costs associated with establishing and maintaining
the Letters of Credit and/or Trust Agreements as described in this Article

The failure of the Company to enforce any provision of this Article shall not
constitute a waiver by the Company of any such provision, irrespective of how
long such failure continues. The past waiver of any provision of this Article,
by the Company, shall not constitute a course of conduct or a waiver of the
Company's rights in the future with respect to that same provision.

ARTICLE 25 - SERVICE OF SUIT

(This Article applies only if the Reinsurer is domiciled outside the United
States of America and/or unauthorized in any state, territory, or district of
the United States of America that has jurisdiction over the Company and in which
a subject suit has been instituted. This Article is not intended to conflict
with or override the parties' obligation to arbitrate their disputes in
accordance with the Arbitration Article.)

In the event of the failure of any Reinsurer hereon to pay any amount claimed to
be due hereunder, such Reinsurer, at the request of the Company, shall submit to
the jurisdiction of a court of competent jurisdiction within the United States
and shall comply with all requirements necessary to give that court
jurisdiction. Nothing in this Article constitutes or should be understood to
constitute a waiver of the Reinsurer's rights to commence an action in any court
of competent jurisdiction in the United States, to remove an action to a United
States District Court, or to seek a transfer of a case to another court as
permitted by the laws of the United

United States which makes provision therefor, the Reinsurer hereon hereby
designates the Superintendent, Commissioner or Director of Insurance or other
officer specified for that purpose in the statute, or the successor or
successors in office, as its true and lawful attorney upon whom may be served
any lawful process in any action, suit or proceeding instituted by or on behalf
of the Company or any beneficiary hereunder, arising out of this Agreement, and
hereby designates the above-named as the person to whom the said officer is
authorized to mail such process or a true copy thereof.

ARTICLE 26 - SEVERABILITY

States of America, or the ruling officials having supervision over insurance
companies, should render illegal this Agreement, or any portion thereof, as to
risks or properties located in the jurisdiction of such authority, either the
Company or the Reinsurer may upon written notice to the other suspend, abrogate,
or amend this Agreement insofar as it relates to risks or properties located
within such jurisdiction to such extent as may be necessary to comply with such
law, regulations, or ruling.
