      event any of the following circumstances occur:

      1.    The Subscribing Reinsurer's policyholders' surplus at the inception
            of this Contract has been reduced by more than 25.0% of the amount
            of surplus (or stamp capacity, in respect of Lloyds Syndicates) 12
            months prior to that date; or

      2.    The Subscribing Reinsurer's policyholders' surplus at any time
            during the term of this Contract has been reduced by more than 25.0%
            of the amount of surplus (or stamp capacity, in respect of Lloyds
            Syndicates) at the date of the Subscribing Reinsurer's most recent
            financial statement filed with regulatory authorities and available
            to the public as of the inception of this Contract; or

      3.    The Subscribing Reinsurer's A.M. Best's rating has been assigned or
            downgraded below A- and/or Standard and Poor's rating has been
            assigned or downgraded below BBB+; or

            the Subscribing Reinsurer to cease writing business; or

      6.    The Subscribing Reinsurer has become insolvent or has been placed
            into liquidation or receivership (whether voluntary or involuntary)
            or proceedings have been instituted against the Subscribing
            Reinsurer for the appointment of a receiver, liquidator,
            rehabilitator, conservator or trustee in bankruptcy, or other agent
            known by whatever name, to take possession of its assets or control
            of its operations; or

      7.    The Subscribing Reinsurer has reinsured its entire liability under
            this Contract without the Company's prior written consent, except
            that this provision shall not apply to any intercompany reinsurance
            or intercompany pooling arrangements entered into by the Subscribing
            Reinsurer; or

      8.    The Subscribing Reinsurer has ceased assuming new and renewal
            property and casualty treaty reinsurance business.

C.    If this Contract is terminated or expires while a loss occurrence covered
      hereunder is in progress, the Reinsurer's liability hereunder shall,
      subject to the other terms and conditions of this Contract, be determined
      as if the entire loss occurrence had occurred prior to the

Page 2



      termination or expiration of this Contract, provided that no part of such
      loss occurrence is claimed against any renewal or replacement of this
      Contract.

            or otherwise, from its participation or membership, whether
            voluntary or involuntary, in any insolvency fund. "Insolvency fund"
            includes any guaranty fund, insolvency fund, plan, pool,
            association, fund or other arrangement, however denominated,
            established or governed, which provides for any assessment of or
            payment or assumption by the Company of part or all of any claim,
            debt, charge, fee or other obligation of an insurer, or its
            successors or assigns, which has been declared by any competent
            authority to be insolvent, or which is otherwise deemed unable to
            meet any claim, debt, charge, fee or other obligation in whole or in
            part.

      4.    Loss or damage caused by or resulting from war, invasion,

            insurrection, military or usurped power, or martial law or
            confiscation by order of any government or public authority, but
            this exclusion shall not apply to loss or damage covered under a
            standard policy with a standard War Exclusion Clause.

      5.    Nuclear risks as defined in the "Nuclear Incident Exclusion Clause -
            Physical Damage - Reinsurance (U.S.A.)" and the "Nuclear Incident
            Exclusion Clause - Physical Damage - Reinsurance (Canada)" attached
            to and forming part of this Contract.

            and/or pollution and/or contamination, other than contamination from
            smoke. Nevertheless, this exclusion does not preclude payment of the
            cost of removing debris of property damaged by a loss otherwise
            covered hereunder, subject always to a limit of 25% of the Company's
            property loss under the applicable original policy.

Page 3



      8.    Losses in respect of transmission and distribution lines and their
            supporting structures other than those on or within 150 meters (or
            500 feet) of the insured's premises.

      9.    Retrocessional business.

      10.   Loss, damage, cost or expense directly or indirectly caused by,
            contributed to by, resulting from or arising out of or in connection
            with any "act of terrorism" as defined in the Terrorism Risk
            Insurance Act of 2002 (the "Act"), regardless of any other cause or
            event contributing concurrently or in any sequence to the loss.

            Notwithstanding the above and subject otherwise to the terms,
            conditions and limitations of this Contract, this Contract will pay
            actual loss or damage (but not related cost or expense) caused by
            any act of terrorism which does not meet the definition of "act of
            terrorism" set forth in the Act or meets the definition of "act of
            terrorism" as set forth in the Act but results in loss under a
            policy that is not included in "property and casualty insurance" as
            defined in the Act, provided, in either case, (a) such loss or
            damage occurs in a line of insurance otherwise covered by this
            Contract, and (b) in no event will this Contract provide coverage
            for loss, damage, cost or expense directly or indirectly caused by,
            contributed to by, resulting from, or arising out of or in
            connection with biological, chemical or nuclear explosion,
            pollution, contamination and/or fire following thereon.

ARTICLE V - RETENTION AND LIMIT

A.    As respects each excess layer of reinsurance coverage provided by this
      Contract, the Company shall retain and be liable for the first amount of
      ultimate net loss, shown as "Company's Retention" for that excess layer in
      Schedule A attached hereto, arising out of each loss occurrence. The
      Reinsurer shall then be liable, as respects each excess layer, for the
      amount by which such ultimate net loss exceeds the Company's applicable
      retention, but the liability of the Reinsurer under each excess layer
      shall not exceed the amount, shown as "Reinsurer's Per Occurrence Limit"
      for that excess layer in Schedule A attached hereto, as respects any one
      loss occurrence.

B.    As respects each excess layer of reinsurance coverage provided by this
      Contract, the Company shall retain at least 5.0% part of a 100% share in
      the interests and liabilities of the "Reinsurer" under each excess layer
      of this Contract.

C.    It is warranted that no claim shall be made under any excess layer of
      coverage provided by this Contract in any one loss occurrence unless at
      least two risks insured or reinsured by the Company are involved in such
      loss occurrence. For purposes hereof, the Company shall be the sole judge
      of what constitutes one risk, but in no event shall a building and its
      contents be considered more than one risk.

ARTICLE VI - REINSTATEMENT

A.    In the event all or any portion of the reinsurance under any excess layer
      of reinsurance coverage provided by this Contract is exhausted by loss,
      the amount so exhausted shall be reinstated immediately from the time the
      loss occurrence commences hereon. For each amount so reinstated the
      Company agrees to pay additional premium equal to the product of the
      following:

Page 4



      1.    The percentage of the occurrence limit for the excess layer
            reinstated (based on the loss paid by the Reinsurer under that
            excess layer); times

      2.    The earned reinsurance premium for the excess layer reinstated for
            the term of this Contract (exclusive of reinstatement premium).

B.    Whenever the Company requests payment by the Reinsurer of any loss under
      any excess layer hereunder, the Company shall submit a statement to the
      Reinsurer of reinstatement premium due the Reinsurer for that excess
      layer. If the earned reinsurance premium for any excess layer for the term
      of this Contract has not been finally determined as of the date of any
      such statement, the calculation of reinstatement premium due for that
      excess layer shall be based on the annual deposit premium for that excess
      layer and shall be readjusted when the earned reinsurance premium for that
      excess layer for the term of this Contract has been finally determined.
      Any reinstatement premium shown to be due the Reinsurer for any excess
      layer as reflected by any such statement (less prior payments, if any, for
      that excess layer) shall be payable by the Company concurrently with
      payment by the Reinsurer of the requested loss for that excess layer. Any
      return reinstatement premium shown to be due the Company shall be remitted
      by the Reinsurer as promptly as possible after receipt and verification of
      the Company's statement.

C.    Notwithstanding anything stated herein, the liability of the Reinsurer
      under any excess layer of reinsurance coverage provided by this Contract
      shall not exceed either of the following:

      1.    The amount, shown as "Reinsurer's Per Occurrence Limit" for that
            excess layer in Schedule A attached hereto, as respects loss or
            losses arising out of any one loss occurrence; or

      2.    The amount, shown as "Reinsurer's Annual Limit" for that excess
            layer in Schedule A attached hereto, in all during the term of this
            Contract.

ARTICLE VII - DEFINITIONS

A.    "Ultimate net loss" as used herein is defined as the sum or sums
      (including loss in excess of policy limits, extra contractual obligations
      and loss adjustment expense, as hereinafter defined) paid or payable by
      the Company in settlement of claims and in satisfaction of judgments
      rendered on account of such claims, after deduction of all salvage, all
      recoveries and all claims on inuring insurance or reinsurance, whether
      collectible or not. With respect to losses arising out of mycotoxins, mold
      or other fungi (hereinafter together referred to as "mold-related
      losses"), only those mold-related losses directly arising out of loss
      occurrences covered hereunder will be included in ultimate net loss.
      Mold-related losses, in and of themselves, shall not be considered an
      event. Nothing herein shall be construed to mean that losses under this
      Contract are not recoverable until the Company's ultimate net loss has
      been ascertained.

      All salvages and recoveries made or received subsequent to a loss
      settlement under this Contract shall be applied as if recovered or
      received prior to the said settlement, and all necessary adjustments shall
      be made by the parties hereto.

B.    "Loss in excess of policy limits" and "extra contractual obligations" as
      used herein shall be defined as follows:

      1.    "Loss in excess of policy limits" shall mean 80.0% of any amount
            paid or payable by the Company in excess of its policy limits, but
            otherwise within the terms of its policy and within the terms of
            this Contract, such loss in excess of the Company's policy limits
            having been incurred because of, but not limited to, failure by the
            Company to settle within the policy limits or by reason of the
            Company's alleged or actual negligence, fraud or bad faith in
            rejecting an offer of settlement or in the preparation of the
            defense or in the trial of an action against its insured or in the
            preparation or prosecution of an appeal consequent upon such an
            action. For purposes of this Contract, loss in excess of policy
            limits arising out of any one loss occurrence shall not exceed 25.0%
            of the contractual loss under all policies involved in the loss
            occurrence.

      2.    "Extra contractual obligations" shall mean 80.0% of any punitive,
            exemplary, compensatory or consequential damages paid or payable by
            the Company, not covered by any other provision of this Contract and
            which arise from the handling of any claim on business subject to
            this Contract, such liabilities arising because of, but not limited
            to, failure by the Company to settle within the policy limits or by
            reason of the Company's alleged or actual negligence, fraud or bad
            faith in rejecting an offer of settlement or in the preparation of
            the defense or in the trial of any action against its insured or in
            the preparation or prosecution of an appeal consequent upon such an
            action. For purposes of this Contract, extra contractual obligations
            arising out of any one loss occurrence shall not exceed 25.0% of the
            contractual loss under all policies involved in the loss occurrence.
            An extra contractual obligation shall be deemed, in all
            circumstances, to have occurred on the same date as the loss covered
            or alleged to be covered under the policy.

      Notwithstanding anything stated herein, this Contract shall not apply to
      any loss in excess of policy limits or any extra contractual obligation
      incurred by the Company as a result of any fraudulent and/or criminal act
      by any officer or director of the Company acting individually or
      collectively or in collusion with any individual or corporation or any
      other organization or party involved in the presentation, defense or
      settlement of any claim covered hereunder.

      If any provision of this paragraph B shall be rendered illegal or
      unenforceable by the laws, regulations or public policy of any state, such
      provision shall be considered void in such state, but this shall not
      affect the validity or enforceability of any other provision of this
      Contract or the enforceability of such provision in any other
      jurisdiction.

C.    "Loss adjustment expense" as used herein shall mean expenses assignable to
      the investigation, appraisal, adjustment, settlement, litigation, defense
      and/or appeal of specific claims, regardless of how such expenses are
      classified for statutory reporting purposes. Loss adjustment expense shall
      include, but not be limited to, court costs, costs of supersedeas and
      appeal bonds, prejudgment interest, postjudgment interest, expenses of
      outside adjusters, legal expenses and costs incurred in connection with
      coverage questions and legal actions connected thereto, and a pro rata
      share of salaries and expenses of the

Page 6



      Company's field employees and expenses of other employees who have been
      temporarily diverted from their normal and customary duties and assigned
      to the field adjustment of losses covered by this Contract. Loss
      adjustment expense shall not include salaries and expenses of the
      Company's regular employees, except as provided above, or office and
      overhead expenses.

ARTICLE VIII - OTHER REINSURANCE

The Company shall be permitted to carry the following:

      1.    Catastrophe excess of loss, including but not limited to catastrophe
            excess of loss as classified by the Company as index, Original Loss
            Warranty (OLW), swaps, and cat-linked covers;

      2.    Any other underlying reinsurance;

      recoveries under which shall inure solely to the benefit of the Company
      and be entirely disregarded in applying all of the provisions of this
      Contract.

ARTICLE IX - LOSS OCCURRENCE

A.    The term "loss occurrence" shall mean the sum of all individual losses
      directly occasioned by any one disaster, accident or loss or series of
      disasters, accidents or losses arising out of one event which occurs
      within the area of one state of the United States or province of Canada
      and states or provinces contiguous thereto and to one another, and the
      Islands of the Caribbean. However, the duration and extent of any one
      "loss occurrence" shall be limited to all individual losses sustained by
      the Company occurring during any period of 168 consecutive hours arising
      out of and directly occasioned by the same event, except that the term
      "loss occurrence" shall be further defined as follows:

      1.    As regards windstorm, hail, tornado, hurricane, cyclone, including
            ensuing collapse and water damage, all individual losses sustained
            by the Company occurring during any period of 72 consecutive hours
            arising out of and directly occasioned by the same event. However,
            the event need not be limited to one state or province or states or
            provinces contiguous thereto.

      2.    As regards riot, riot attending a strike, civil commotion, vandalism
            and malicious mischief, all individual losses sustained by the
            Company occurring during any period of 72 consecutive hours within
            the area of one municipality or county and the municipalities or
            counties contiguous thereto arising out of and directly occasioned
            by the same event. The maximum duration of 72 consecutive hours may
            be extended in respect of individual losses which occur beyond such
            72 consecutive hours during the continued occupation of an assured's
            premises by strikers, provided such occupation commenced during the
            aforesaid period.

      3.    As regards earthquake (the epicenter of which need not necessarily
            be within the territorial confines referred to in paragraph A of
            this Article) and fire following directly

Page 7



            occasioned by the earthquake, only those individual fire losses
            which commence during the period of 168 consecutive hours may be
            included in the Company's "loss occurrence."

      4.    As regards "freeze," only individual losses directly occasioned by
            collapse, breakage of glass and water damage (caused by bursting
            frozen pipes and tanks) may be included in the Company's "loss
            occurrence."

B.    For all "loss occurrences" other than those referred to in subparagraph 2
      of paragraph A above, the Company may choose the date and time when any
      such period of consecutive hours commences, provided that it is not
      earlier than the date and time of the occurrence of the first recorded
      individual loss sustained by the Company arising out of that disaster,
      accident or loss, and provided that only one such period of 168
      consecutive hours shall apply with respect to one event, except for any
      "loss occurrence" referred to in subparagraph 1 of paragraph A above where
      only one such period of 72 consecutive hours shall apply with respect to
      one event.

C.    As respects those "loss occurrences" referred to in subparagraph 2 of
      paragraph A above, the Company may choose the date and time when any such
      period of consecutive hours commences. If the disaster, accident or loss
      occasioned by the event is of greater duration than 72 consecutive hours,
      then the Company may divide that disaster, accident or loss into two or
      more "loss occurrences," provided that no two periods overlap and no
      individual loss is included in more than one such period, and provided
      that no period commences earlier than the date and time of the occurrence
      of the first recorded individual loss sustained by the Company arising out
      of that disaster, accident or loss.

D.    No individual losses occasioned by an event that would be covered by 72
      hours clauses may be included in any "loss occurrence" claimed under the
      168 hours provision.

E.    Losses directly or indirectly occasioned by:

      1.    Loss of, alteration of, or damage to; or

      2.    A reduction in the functionality, availability or operation of;

      a computer system, hardware, program, software, data, information
      repository, microchip, integrated circuit, or similar device in computer
      equipment or non-computer equipment, whether the property of the
      policyholder of the Company or not, do not in and of themselves constitute
      an event unless arising out of one or more of the following perils:

            fire, lightning, explosion, aircraft or vehicle impact, falling
            objects, windstorm, hail, tornado, cyclone, hurricane, earthquake,
            volcano, tsunami, flood, freeze or weight of snow.

ARTICLE X - LOSS NOTICES AND SETTLEMENTS

A.    Whenever losses sustained by the Company appear likely to result in a
      claim hereunder, the Company shall notify the Reinsurer, and the Reinsurer
      shall have the right to participate in the adjustment of such losses at
      its own expense.

B.    All loss settlements made by the Company, provided they are within the
      terms of this Contract, shall be binding upon the Reinsurer, and the
      Reinsurer agrees to pay all amounts

Page 9



      for which it may be liable upon receipt of reasonable evidence of the
      amount paid (or scheduled to be paid) by the Company.

ARTICLE XI - SALVAGE AND SUBROGATION

The Reinsurer shall be credited with salvage (i.e., reimbursement obtained or
recovery made by the Company, less the actual cost, excluding salaries of
officials and employees of the Company and sums paid to attorneys as retainer,
of obtaining such reimbursement or making such recovery) on account of claims
and settlements involving reinsurance hereunder. Salvage thereon shall always be
used to reimburse the excess carriers in the reverse order of their priority
according to their participation before being used in any way to reimburse the
Company for its primary loss. The Company hereby agrees to enforce its rights to
salvage or subrogation relating to any loss, a part of which loss was sustained
by the Reinsurer, and to prosecute all claims arising out of such rights.

ARTICLE XII - REINSURANCE PREMIUM

A.    As premium for each excess layer of reinsurance coverage provided by this
      Contract, the Company shall pay the Reinsurer the greater of the
      following:

      1.    The amount, shown as "Annual Minimum Premium" for that excess layer
            in Schedule A attached hereto (or a pro rata portion thereof if the
            term of this Contract is less than 12 months as set forth in Article
            II - Commencement and Termination); or

      2.    The percentage, shown as "Premium Rate" for that excess layer in
            Schedule A attached hereto, of the Company's net earned premium for
            the term of this Contract.

B.    The Company shall pay the Reinsurer an annual deposit premium for each
      excess layer of the amount, shown as "Annual Deposit Premium" for that
      excess layer in Schedule A attached hereto, in four equal installments of
      the amount, shown as "Quarterly Deposit Premium" for that excess layer in
      Schedule A attached hereto, on July 1, 2003, October 1, 2003, January 1,
      2004 and April 1, 2004. However, if this Contract is terminated prior to
      July 1, 2004, no deposit premium installments shall be due after the
      effective date of termination.

C.    As promptly as possible after the effective date of termination or
      expiration of this Contract, the Company shall provide a report to the
      Reinsurer setting forth the premium due hereunder for each excess layer,
      computed in accordance with paragraph A, and any additional premium due
      the Reinsurer or return premium due the Company for each such excess layer
      shall be remitted promptly.

D.    "Net earned premium" as used herein is defined as gross earned premium of
      the Company for the classes of business reinsured hereunder, less the
      earned portion of premiums ceded by the Company for reinsurance which
      inures to the benefit of this Contract.

Page 10



ARTICLE XIII - OFFSET (BRMA 36C)

The Company and the Reinsurer shall have the right to offset any balance or
amounts due from one party to the other under the terms of this Contract. The
party asserting the right of offset may exercise such right any time whether the
balances due are on account of premiums or losses or otherwise.

ARTICLE XIV - ACCESS TO RECORDS

The Reinsurer or its designated representatives shall have access at any
reasonable time, with prior notice to the Company, to all records of the Company
which pertain in any way to this reinsurance.

ARTICLE XV - LIABILITY OF THE REINSURER

A.    The liability of the Reinsurer shall follow that of the Company in every
      case and be subject in all respects to all the general and specific
      stipulations, clauses, waivers and modifications of the Company's policies
      and any endorsements thereon. However, in no event shall this be construed
      in any way to provide coverage outside the terms and conditions set forth
      in this Contract.

B.    Nothing herein shall in any manner create any obligations or establish any
      rights against the Reinsurer in favor of any third party or any persons
      not parties to this Contract.

ARTICLE XVI - NET RETAINED LINES (BRMA 32E)

A.    This Contract applies only to that portion of any policy which the Company
      retains net for its own account (prior to deduction of any underlying
      reinsurance specifically permitted in this Contract), and in calculating
      the amount of any loss hereunder and also in computing the amount or
      amounts in excess of which this Contract attaches, only loss or losses in
      respect of that portion of any policy which the Company retains net for
      its own account shall be included.

B.    The amount of the Reinsurer's liability hereunder in respect of any loss
      or losses shall not be increased by reason of the inability of the Company
      to collect from any other reinsurer(s), whether specific or general, any
      amounts which may have become due from such reinsurer(s), whether such
      inability arises from the insolvency of such other reinsurer(s) or
      otherwise.

ARTICLE XVII - ERRORS AND OMISSIONS (BRMA 14E)

Any inadvertent delay, omission or error shall not be held to relieve either
party hereto from any liability which would attach to it hereunder if such
delay, omission or error had not been made, provided such delay, omission or
error is rectified upon discovery.

Page 11



ARTICLE XVIII - CURRENCY (BRMA 12A)

A.    Whenever the word "Dollars" or the "$" sign appears in this Contract, they
      shall be construed to mean United States Dollars and all transactions
      under this Contract shall be in United States Dollars.

B.    Amounts paid or received by the Company in any other currency shall be
      converted to United States Dollars at the rate of exchange at the date
      such transaction is entered on the books of the Company.

ARTICLE XIX - TAXES (BRMA 50C)

In consideration of the terms under which this Contract is issued, the Company
will not claim a deduction in respect of the premium hereon when making tax
returns, other than income or profits tax returns, to any state or territory of
the United States of America, the District of Columbia or Canada.

ARTICLE XX - FEDERAL EXCISE TAX (BRMA 17A)

(Applicable to those reinsurers, excepting Underwriters at Lloyd's London and
other reinsurers exempt from Federal Excise Tax, who are domiciled outside the
United States of America.)

A.    The Reinsurer has agreed to allow for the purpose of paying the Federal
      Excise Tax the applicable percentage of the premium payable hereon as
      imposed under Section 4371 of the Internal Revenue Code to the extent such
      premium is subject to the Federal Excise Tax.

B.    In the event of any return of premium becoming due hereunder the Reinsurer
      will deduct the applicable percentage from the return premium payable
      hereon and the Company or its agent should take steps to recover the tax
      from the United States Government.

ARTICLE XXI - RESERVES AND LETTERS OF CREDIT

A.    If the Reinsurer is unauthorized in any state of the United States of
      America or the District of Columbia, or in the event the Reinsurer's A.M.
      Best's rating has been assigned or downgraded below A-, the Reinsurer
      agrees to fund its share of the Company's ceded United States outstanding
      loss and loss adjustment expense reserves (including all case reserves
      plus any reasonable amount estimated to be unreported from known loss
      occurrences) by:

      1.    Clean, irrevocable and unconditional letters of credit issued and
            confirmed, if confirmation is required by the insurance regulatory
            authorities involved, by a bank or banks meeting the NAIC Securities
            Valuation Office credit standards for issuers of letters of credit
            and acceptable to said insurance regulatory authorities; and/or

      2.    Escrow accounts for the benefit of the Company; and/or

Page 12



      3.    Cash advances;

      The Reinsurer, at its sole option, may fund in other than cash if its
      method and form of funding are acceptable to the Company.

B.    If the Reinsurer is unauthorized in any province or jurisdiction of
      Canada, the Reinsurer agrees to fund 115% of its share of the Company's
      ceded Canadian outstanding loss and loss adjustment expense reserves
      (including all case reserves plus any reasonable amount estimated to be
      unreported from known loss occurrences) by:

      1.    A clean, irrevocable and unconditional letter of credit issued and
            confirmed, if confirmation is required by the insurance regulatory
            authorities involved, by a Canadian bank or banks meeting the NAIC
            Securities Valuation Office credit standards for issuers of letters
            of credit and acceptable to said insurance regulatory authorities,
            for no more than 15/115ths of the total funding required; and/or

      2.    Cash advances for the remaining balance of the funding required;

C.    With regard to funding in whole or in part by letters of credit, it is
      agreed that each letter of credit will be in a form acceptable to the
      Company, will be issued for a term of at least one year and will include
      an "evergreen clause," which automatically extends the term for at least
      one additional year at each expiration date unless written notice of
      non-renewal is given to the Company not less than 30 days prior to said
      expiration date. The Company and the Reinsurer further agree,
      notwithstanding anything to the contrary in this Contract, that said
      letters of credit may be drawn upon by the Company or its successors in
      interest at any time, without diminution because of the insolvency of the
      Company or the Reinsurer, but only for one or more of the following
      purposes:

      1.    To reimburse itself for the Reinsurer's share of losses and/or loss
            adjustment expense paid under the terms of policies reinsured
            hereunder, unless paid in cash by the Reinsurer;

      2.    To reimburse itself for the Reinsurer's share of any other amounts
            which are due hereunder, unless paid in cash by the Reinsurer;

      3.    To fund a cash account in an amount equal to the Reinsurer's share
            of any ceded outstanding loss and loss adjustment expense reserves
            (including all case reserves plus any reasonable amount estimated to
            be unreported from known loss occurrences) funded by means of a
            letter of credit which is under non-renewal notice, if said letter
            of credit has not been renewed or replaced by the Reinsurer 10 days
            prior to its expiration date;

      4.    To refund to the Reinsurer any sum in excess of the actual amount
            required to fund the Reinsurer's share of the Company's ceded
            outstanding loss and loss adjustment expense reserves (including all
            case reserves plus any reasonable amount estimated to be unreported
            from known loss occurrences), if so requested by the Reinsurer.

      In the event the amount drawn by the Company on any letter of credit is in
      excess of the actual amount required for C(1) or C(3), or in the case of
      C(2), the actual amount

Page 13



      determined to be due, the Company shall promptly return to the Reinsurer
      the excess amount so drawn.

ARTICLE XXII - INSOLVENCY

A.    In the event of the insolvency of one or more of the reinsured companies,
      this reinsurance shall be payable directly to the company, or to its
      liquidator, receiver, conservator or statutory successor on the basis of
      the liability of the company without diminution because of the insolvency
      of the company or because the liquidator, receiver, conservator or
      statutory successor of the company has failed to pay all or a portion of
      any claim. It is agreed, however, that the liquidator, receiver,
      conservator or statutory successor of the company shall give written
      notice to the Reinsurer of the pendency of a claim against the company
      indicating the policy insured which claim would involve a possible
      liability on the part of the Reinsurer within a reasonable time after such
      claim is filed in the conservation or liquidation proceeding or in the
      receivership, and that 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
      that it may deem available to the company or its liquidator, receiver,
      conservator or statutory successor. The expense thus incurred by the
      Reinsurer shall be chargeable, subject to the approval of the court,
      against the company as part of the expense of conservation or liquidation
      to the extent of a pro rata share of the benefit which may accrue to the
      company solely as a result of the defense undertaken by the Reinsurer.

B.    Where two or more reinsurers are involved in the same claim and a majority
      in interest elect to interpose defense to such claim, the expense shall be
      apportioned in accordance with the terms of this Contract as though such
      expense had been incurred by the insolvent company.

ARTICLE XXIII - ARBITRATION

A.    As a condition precedent to any right of action hereunder, in the event of
      any dispute or difference of opinion hereafter arising with respect to
      this Contract, it is hereby mutually agreed that such dispute or
      difference of opinion shall be submitted to arbitration. One Arbiter shall
      be chosen by the Company, the other by the Reinsurer, and an Umpire shall
      be chosen by the two Arbiters before they enter upon arbitration, all of
      whom shall be active or retired disinterested executive officers of
      insurance or reinsurance companies or Lloyd's London Underwriters. In the
      event that either party should fail to choose an Arbiter within 30 days
      following a written request by the other party to do so, the requesting
      party may choose two Arbiters who shall in turn choose an Umpire before
      entering upon arbitration. If the two Arbiters fail to agree upon the
      selection of an Umpire within 30 days following their appointment, the two
      Arbiters shall request the American Arbitration Association to appoint the
      Umpire. If the American Arbitration Association fails to appoint the
      Umpire within 30 days after it has been requested to do so, either party
      may request a justice of a Court of general jurisdiction of the state in
      which the arbitration is to be held to appoint the Umpire.

B.    Each party shall present its case to the Arbiters within 30 days following
      the date of appointment of the Umpire. The Arbiters shall consider this
      Contract as an honorable

Page 14



      engagement rather than merely as a legal obligation and they are relieved
      of all judicial formalities and may abstain from following the strict
      rules of law. The decision of the Arbiters shall be final and binding on
      both parties; but failing to agree, they shall call in the Umpire and the
      decision of the majority shall be final and binding upon both parties.
      Judgment upon the final decision of the Arbiters may be entered in any
      court of competent jurisdiction.

C.    If more than one reinsurer is involved in the same dispute, all such
      reinsurers shall constitute and act as one party for purposes of this
      Article and communications shall be made by the Company to each of the
      reinsurers constituting one party, provided, however, that nothing herein
      shall impair the rights of such reinsurers to assert several, rather than
      joint, defenses or claims, nor be construed as changing the liability of
      the reinsurers participating under the terms of this Contract from several
      to joint.

D.    Each party shall bear the expense of its own Arbiter, and shall jointly
      and equally bear with the other the expense of the Umpire and of the
      arbitration. In the event that the two Arbiters are chosen by one party,
      as above provided, the expense of the Arbiters, the Umpire and the
      arbitration shall be equally divided between the two parties.

E.    Any arbitration proceedings shall take place at a location mutually agreed
      upon by the parties to this Contract, but notwithstanding the location of
      the arbitration, all proceedings pursuant hereto shall be governed by the
      law of the State of New York.

ARTICLE XXIV - SERVICE OF SUIT (BRMA 49C)

(Applicable if the Reinsurer is not domiciled in the United States of America,
and/or is not authorized in any State, Territory or District of the United
States where authorization is required by insurance regulatory authorities)

A.    It is agreed that in the event the Reinsurer fails to pay any amount
      claimed to be due hereunder, the Reinsurer, at the request of the Company,

            Mechanisms to meet its liability.

      (ii)  Any claim against such "Coastal Pool" and/or "Fair Plan" and/or

                   for the accounting year in which the loss occurrence
                   commenced; and

             (ii)  The relevant entity's total losses in such loss occurrence.

             Any assessments for accounting years subsequent to that in which

             respect of any residual market mechanism, the Ultimate Net Loss
             hereunder shall not include any monies expended to purchase or
             retire bonds as a consequence of being a member of such residual
             market mechanism. For the purposes of this Contract, the Company
             may not include in the Ultimate Net Loss any assessment or any
             percentage assessment levied by any residual market mechanism to
             meet the obligations of an insolvent insurer member or other party,
             or to meet any obligations arising from the deferment by any
             residual market mechanism of the collection of monies.
