      retaliating against or responding to any act of terrorism.

      Notwithstanding the above and subject otherwise to the terms, conditions,
      and limitations of this Contract, in respect only of personal lines this
      Contract will pay actual loss or damage (but not related cost or expense)
      caused by any act of terrorism provided such act is not directly or
      indirectly caused by, contributed to by, resulting from, or arising out of
      or in connection with biological, chemical, or nuclear pollution or
      contamination.

  10. Loss or liability in any way or to any extent arising out of the actual
      or alleged presence or actual, alleged or threatened presence of fungi
      including, but not limited to, mold, mildew, mycotoxins, microbial
      volatile organic compounds or other "microbial contamination". This

            given or which should have been given in connection with the above;
            and

         b. Any obligation to share damages with or repay someone else who must
            pay damages because of such injury or damage.

      related to the presence of fungi, mold, mildew, mycotoxins, microbial
      volatile organic compounds or spores, including, without limitation,
      Penicillium, Aspergillus, Fusarium, Aspergillus Flavus and Stachybotrys
      chartarum.

      Losses resulting from the above causes do not in and of themselves
      constitute an event unless arising out of one or more of the following
      perils, in which case this exclusion does not apply:

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

      Notice of any claims for mold-related losses must be given by the Company
      to the Reinsurer, in writing, within 24 months after the commencement date
      of the loss occurrence to which such claims relate.

                                   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. 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.

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 90.0% of any amount paid or
      payable by the Company in excess of its policy limits, but otherwise
      within the terms of its policy, 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 any action against its insured or reinsured or in the preparation or
      prosecution of an appeal consequent upon such an action.

   2. "Extra contractual obligations" shall mean 90.0% 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 reinsured or in the preparation or
      prosecution of an appeal consequent upon such an action. 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, the amount included in the ultimate
   net loss for any one loss occurrence as respects loss in excess of policy
   limits and extra contractual obligations shall not exceed 25.0% of the
   Company's indemnity loss hereunder arising out of that loss occurrence.

   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, declaratory judgments, interest on judgments,
   expenses of outside adjusters, and a pro rata share of the salaries and
   expenses of the Company's field employees according to the time occupied
   adjusting such losses and expenses of the Company's officials

   incurred in connection with the losses, but shall not include office expenses
   or salaries of the Company's regular employees.

                                  LATE PAYMENTS

A. The provisions of this Article shall not be implemented unless specifically
   invoked, in writing, by one of the parties to this Contract.

B. In the event any premium, loss or other payment due either party is not
   received by the intermediary named herein (hereinafter referred to as the
   "Intermediary") by the payment due date, the party to whom payment is due
   may, by notifying the Intermediary in writing, require the debtor party to
   pay, and the debtor party agrees to pay, an interest penalty on the amount
   past due calculated for each such payment on the last business day of each
   month as follows:

   1. The number of full days which have expired since the due date or the last
      monthly calculation, whichever the lesser, times

   2. 1/365ths of the six-month United States Treasury Bill Rate as quoted in
      The Wall Street Journal on the first business day of the month for which
      the calculation is made; times

   3. The amount past due, including accrued interest.

   It is agreed that interest shall accumulate until payment of the original
   amount due plus interest penalties have been received by the Intermediary.

C. The establishment of the due date shall, for purposes of this Article, be
   determined as follows:

   1. As respects the payment of routine deposits and premiums due the
      Reinsurer, the due date shall be as provided for in the applicable section
      of this Contract. In the event a due date is not specifically stated for a
      given payment, it shall be deemed due 30 days after the date of
      transmittal by the Intermediary of the initial billing for each such
      payment.

   2. Any claim or loss payment due the Company hereunder shall be deemed due 10
      business days after the proof of loss or demand for payment is transmitted
      to the Reinsurer. If such loss or claim payment is not received within the
      10 days, interest will accrue on the payment or amount overdue in
      accordance with paragraph B above, from the date the proof of loss or
      demand for payment was transmitted to the Reinsurer.

   3. As respects any payment, adjustment or return due either party not
      otherwise provided for in subparagraphs 1 and 2 of paragraph C above, the
      due date shall be as provided for in the applicable section of this
      Contract. In the event a due date is not specifically stated for a given
      payment, it shall be deemed due 10 business days following transmittal of
      written notification that the provisions of this Article have been
      invoked.

   For purposes of interest calculations only, amounts due hereunder shall be
   deemed paid upon receipt by the Intermediary.

D. Nothing herein shall be construed as limiting or prohibiting a subscribing
   reinsurer from contesting the validity of any claim, or from participating in
   the defense of any claim or suit, or prohibiting either party from contesting
   the validity of any payment or from initiating any arbitration or other
   proceeding in accordance with the provisions of this Contract. If the debtor
   party prevails in an arbitration or other proceeding, then any interest
   penalties due hereunder on the amount in dispute shall be null and void. If
   the debtor party loses in such proceeding, then the interest penalty on the
   amount determined to be due hereunder shall be calculated in accordance with
   the provisions set forth above unless otherwise determined by such
   proceedings. If a debtor party advances payment of any amount it is
   contesting, and proves to be correct in its contestation, either in whole or
   in part, the other party shall reimburse the debtor party for any such excess
   payment made plus interest on the excess amount calculated in accordance with
   this Article.

E. Interest penalties arising out of the application of this Article that are
   $100 or less from any party shall be waived unless there is a pattern of late
   payments consisting of three or more items over the course of any 12-month
   period.

                                NON BRMA ARTICLES

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. 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 insured'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 the introductory portion of
      this paragraph) and fire following directly 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."

   5. As regards firestorms, brush fires, and other fires or series of fires,
      irrespective of origin (except as provided in subparagraphs 2 and 3
      above), which spread through trees, grassland or other vegetation, all
      individual losses sustained by the Company which occur during any period
      of 168 consecutive hours within a 100-mile radius of any one fixed point
      selected by the Company may be included in the Company's "loss
      occurrence." However, an individual loss subject to this subparagraph
      cannot be included in more than one "loss occurrence."

B. For all those "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, regardless of
   the duration of the event.

C. As respects those "loss occurrences" referred to in subparagraph 2 of
   paragraph A above, 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
   no two periods overlap and no individual loss is included in more than one
   such period and

                                                                 [BENFIELD LOGO]

   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.

FLORIDA HURRICANE CATASTROPHE FUND

A. Any loss reimbursement paid or payable to the Company under the Florida
   Hurricane Catastrophe Fund (FHCF) as a result of loss occurrences commencing
   during the term of this Contract shall inure to the benefit of this Contract.
   Further, any FHCF loss reimbursement shall be deemed to be paid to the
   Company in accordance with the reimbursement contract between the Company and
   the State Board of Administration of the State of Florida at the full payout
   level set forth therein and will be deemed not to be reduced by any reduction
   or exhaustion of the FHCF's claims paying capacity.

B. Prior to the determination of the Company's FHCF retention and payout, if
   any, under the reimbursement contract, the Reinsurer's liability hereunder
   will be determined provisionally based on the projected payout, determined in
   accordance with the provisions of the reimbursement contract. Following
   determination of the payout under the reimbursement contract, the ultimate
   net loss under this Contract will be recalculated. If, as a result of such
   calculation, the loss to the Reinsurer in any one loss occurrence is less
   than the amount previously paid by the Reinsurer, the Company shall promptly
   remit the difference to the Reinsurer. If the loss to the Reinsurer in any
   one loss occurrence is greater than the amount previously paid by the
   Reinsurer, the Reinsurer shall promptly remit the difference to the Company.

C. If an FHCF reimbursement amount is based on the Company's losses in more than
   one loss occurrence and the FHCF does not designate the amount allocable to
   each loss occurrence, the FHCF reimbursement amount shall be prorated in the
   proportion that the Company's losses in each loss occurrence bear to the
   Company's total losses arising out of all loss occurrences to which the FHCF
   reimbursement applies.

D. Any reimbursement premiums or emergency assessment paid by the Company under
   the FHCF shall be deemed to be premiums paid for inuring reinsurance.

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

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

                                                                 [BENFIELD LOGO]

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.

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.

RESERVE REQUIREMENTS

A. If the Reinsurer is unauthorized in any state of the United States of America
   or the District of Columbia, the Reinsurer agrees to fund its share of the
   Company's ceded United States unearned premium and 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

   3. Cash advances;

   if, without such funding, a penalty would accrue to the Company on any
   financial statement it is required to file with the insurance regulatory
   authorities involved. The Reinsurer, at its sole option, may fund in other
   than cash if its method and form of funding are acceptable to the insurance
   regulatory authorities involved.

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 unearned premium and 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;

   if, without such funding, a penalty would accrue to the Company on any
   financial statement it is required to file with the insurance regulatory
   authorities involved.

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 insurance
   regulatory authorities involved, 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

                                                                 [BENFIELD LOGO]

   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 unearned premiums
      returned to insureds on account of policy cancellations, unless paid in
      cash by the Reinsurer;

   2. 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;

   3. To reimburse itself for the Reinsurer's share of any other amounts claimed
      to be due hereunder, unless paid in cash by the Reinsurer;

   4. To fund a cash account in an amount equal to the Reinsurer's share of any
      ceded unearned premium and/or 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;

   5. 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 unearned premium
      and/or 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), C(2) or C(4), or in the case
   of C(3), the actual amount determined to be due, the Company shall promptly
   return to the Reinsurer the excess amount so drawn.

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 or bond
   reinsured 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 company.

C. It is further understood and agreed that, in the event of the insolvency of
   one or more of the reinsured companies, the reinsurance under this Contract
   shall be payable directly by the Reinsurer

Page 13

                                                                 [BENFIELD LOGO]

   to the company or to its liquidator, receiver or statutory successor, except
   as provided by Section 4118(a) of the New York Insurance Law or except (1)
   where this Contract specifically provides another payee of such reinsurance
   in the event of the insolvency of the company or (2) where the Reinsurer with
   the consent of the direct insured or insureds has assumed such policy
   obligations of the company as direct obligations of the Reinsurer to the
   payees under such policies and in substitution for the obligations of the
   company to such payees.

ARBITRATION

A. As a condition precedent to any right of action hereunder, any dispute or
   difference between the Company and any Reinsurer relating to the
   interpretation or performance of this Contract, including its formation or
   validity, or any transaction under this Contract, whether arising before or
   after termination, shall be submitted to arbitration.

B. 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
   provided that communication shall be made by the Company to each of the
   reinsurers constituting the one party, and provided, however, that nothing
   therein 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 Reinsurer under the terms of this Contract from several to joint.

C. Upon written request of any party, each party shall choose an arbitrator and
   the two chosen shall select a third arbitrator. If either party refuses or
   neglects to appoint an arbitrator within 30 days after receipt of the written
   request for arbitration, the requesting party may appoint a second
   arbitrator. If the two arbitrators fail to agree on the selection of a third
   arbitrator within 30 days of their appointment, the Company shall petition
   the American Arbitration Association to appoint the third arbitrator. If the
   American Arbitration Association fails to appoint the third arbitrator 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 third arbitrator. All arbitrators
   shall be active or retired officers of insurance or reinsurance companies, or
   Lloyd's London Underwriters, and disinterested in the outcome of the
   arbitration. Each party shall submit its case to the arbitrators within 30
   days of the appointment of the third arbitrator.

D. The parties hereby waive all objections to the method of selection of the
   arbitrators, it being the intention of both sides that all the arbitrators be
   chosen from those submitted by the parties.

E. The arbitrators shall have the power to determine all procedural rules for
   the holding of the arbitration including but not limited to inspection of
   documents, examination of witnesses and any other matter relating to the
   conduct of the arbitration. The arbitrators shall interpret this Contract as
   an honorable engagement and not as merely a legal obligation; they are
   relieved of all judicial formalities and may abstain from following the
   strict rules of law. The arbitrators may award interest and costs. Each party
   shall bear the expense of its own arbitrator and shall share equally with the
   other party the expenses of the third arbitrator and of the arbitration.

F. The decision in writing of the majority of the arbitrators shall be final and
   binding upon both parties. Judgment may be entered upon the final decision of
   the arbitrators in any court having jurisdiction. The arbitration shall take
   place in Pinellas Park, Florida, unless otherwise mutually agreed between the
   Company and the Reinsurer.

G. This Article shall remain in full force and effect in the event any other
   provision of this Contract shall be found invalid or non-binding.

H. All time limitations stated in this Article may be amended by mutual consent
   of the parties, and will be amended automatically to the extent made
   necessary by any circumstances beyond the control of the parties.

AGENCY AGREEMENT

If more than one reinsured company is named as a party to this Contract, the
first named company shall be deemed the agent of the other reinsured companies
for purposes of sending or receiving notices required by the terms and
conditions of this Contract, and for purposes of remitting or receiving any
monies due any party.

GOVERNING LAW

This Contract shall be governed as to performance, administration and
interpretation by the laws of the State of Florida exclusive of the rules with
respect to conflicts of law, except as to rules with respect to credit for
reinsurance in which case the applicable rules of all states shall apply.

CONFIDENTIALITY

The Reinsurer, except with the express prior written consent of the Company,
shall not directly or indirectly, communicate, disclose or divulge to any third
party, any knowledge or information that may be acquired either directly or
indirectly as a result of the inspection of the Company's books, records and
papers. The restrictions as outlined in this Article shall not apply to
communication or disclosures that the Reinsurer is required to make to its
statutory auditors, retrocessionaires, legal counsel, arbitrators involved in
any arbitration procedures under this Contract or disclosures required upon
subpoena or other dully-issued order of a court or other governmental agency or
regulatory authority.

SEVERABILITY

If any provision of this Contract should be invalid under applicable laws, the
latter shall control but only to the extent of the conflict without affecting
the remaining provisions of this Contract.

SERVICE OF SUIT

(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. This
Article is not intended to conflict with or override the parties' obligations to
arbitrate their disputes in accordance with the Arbitration Article)

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, will
   submit to the jurisdiction of any court of competent jurisdiction within the
   United States. 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 States or of any state in the
   United States.

   B. Further, pursuant to any statute of any state, territory or district of
      the United States which makes provision therefore, the Reinsurer hereby
      designates the party named in its Interests and Liabilities Agreement, or
      if no party is named therein, the Superintendent, Commissioner or Director
      of Insurance or other officer specified for that purpose in the statute,
      or his 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 Contract.

        is made against the Company by CPIC, the maximum loss that the Company
        may include in the Ultimate Net Loss in respect of any loss occurrence
        hereunder shall not exceed the lesser of:

        (a) The Company's assessment from CPIC for the accounting year in which
            the loss occurrence commenced, or

        (b) The product of the following:

            (i)  The Company's percentage participation in CPIC for the
            accounting year in which the loss occurrence commenced; and

occurrence commenced may not be included in the Ultimate Net Loss hereunder.

   DATA from back-up or from originals of a previous generation. These costs
   will not include research and engineering nor any costs of recreating,
   gathering or assembling such ELECTRONIC DATA. If the media is not repaired,
   replaced or restored the basis of valuation shall be the cost of the blank
