                          REINSURANCE TREATY AGREEMENT

                                    PREAMBLE


This Agreement is made and entered into by and between the Reinsured and the
Reinsurer, as shown on the cover sheet of this Agreement, on the terms and
conditions contained in this Agreement. Except as specifically and expressly
provided for in Article 17 of this Agreement, the provisions of this Agreement
are intended solely for the benefit of the Reinsured and Reinsurer and nothing
in this Agreement shall create or be construed to create any obligations to or
establish any rights against any party to this Agreement in favor of any third
parties whether they be insureds, claimants, or other third parties.

The Reinsured has entered into a Management Agreement with Syndicated Services
Company, Inc. ("Manager") pursuant to which Manager provides services to the
Reinsured regarding the business submitted by the Program Manager to the
Reinsured and is the subject of this Agreement. Manager will provide services to
Reinsured and Reinsurer as respects the business submitted by the Program
Manager as provided in this Agreement.

                                    ARTICLE 1

BUSINESS COVERED UNDER THIS AGREEMENT

This Agreement applies to all "Policies" issued by Program Manager on behalf of
the Reinsured pursuant to the Program Manager Agreement between those parties
dated January 1, 2000. The term "Policies" and "Policy" shall include policies,
contracts, certificates, or binders of insurance including endorsements and
other modifications thereto, issued.

                                    ARTICLE 2

AMOUNT OF COVER

1.       QUOTA SHARE

         The Reinsured agrees to cede and Reinsurer agrees to accept by way of
         quota share reinsurance a 100% (one hundred percent) share
         ("Reinsurer's Quota Share") of all Loss and Loss Expenses, both as
         defined herein.

2.       LOSS AND LOSS EXPENSES

         The term "Loss" shall mean the actual amount that the Reinsured is
         liable to pay for claims, demands or losses under any Policies.

<PAGE>   4

         The term "Loss Expenses" shall mean the actual amount of expenses that
         the Reinsured incurs in the investigation, adjustment, appraisal and
         defense of all claims, demands, and losses under the Policies,
         including costs of any rescission or declaratory judgment action
         arising out of or in connection with the Policies, and shall exclude
         general office expenses, overheads and salaries of the Reinsured's or
         the Program Manager's employees, except for (1) Reinsured's staff
         attorneys representing insureds in the defense of claims, demands or
         losses and (2) Reinsured's Claims Division personnel to the extent
         permitted by the Claims Mandate as defined herein. It is agreed that
         external legal costs incurred by the Program Manager shall be payable
         by Reinsurers as Loss Expenses where such costs are allocable against
         specific claims. Nothing in this Agreement shall be construed as
         meaning that Loss and Loss Expenses are not recoverable hereunder until
         the ultimate actual loss to the Reinsured has been ascertained.

         All salvage and subrogation recoveries actually made by the Reinsured
         incident to Loss and Loss Expense payments by Reinsured and all amounts
         recoverable under all other reinsurance inuring to the benefit of this
         Agreement shall be deducted in arriving at the amount of the
         Reinsurer's liability for Loss and Loss Expenses. All salvages,
         recoveries and payments recovered or received subsequent to a loss
         settlement under this Agreement shall be applied as if recovered or
         received prior to said settlement and all necessary adjustments shall
         be made by the parties hereto.

         The amount of the Reinsurer's liability for Loss and Loss Expenses
         shall not be increased by reason of the inability of the Reinsured to
         collect from any other Reinsurers, whether specific or general, any
         amounts which may have become due from them whether such inability
         arises from insolvency of such other Reinsurers or otherwise.

3.       EXTRA CONTRACTUAL OBLIGATIONS AND LOSS IN EXCESS OF POLICY
         LIMITS

         Reinsurer shall pay Reinsurer's Quota Share of any liability incurred
         by Reinsured as the result of any Extra Contractual Obligations or Loss
         in Excess of Policy Limits, both as defined herein, in addition to any
         liability incurred by the Reinsured for Loss or Loss Expenses related
         to the claim, demand or loss which generated the Extra Contractual
         Obligations or Loss in Excess of Policy Limits.

         The term "Extra Contractual Obligations" shall mean those liabilities
         of the Reinsured not covered under any other provision of this
         Agreement and which arise from the handling of any demand, claim or
         loss covered under this Agreement, such liabilities arising because of,
         but not limited to, the following: failure by the Reinsured to settle
         within the policy limit, or by reason of alleged or actual
         negligence 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 action.

         The term "Loss in Excess of Policy Limits" shall mean any liability of
         the Reinsured arising because of failure to  settle within the policy
         limit or by reason of alleged or actual
<PAGE>   5

         negligence, 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 any appeal consequent
         upon such action.

         The date on which any Extra Contractual Obligations or Loss in Excess
         of Policy Limits is incurred by the Reinsured shall be deemed to be the
         date of the insured's demand, claim, or loss under the Policy. Extra
         Contractual Obligations and Loss in Excess of Policy Limits shall not
         include any liabilities incurred by the Reinsured due to the fraud of a
         member of its Board of Directors or one or more of its officers acting
         individually or collectively or in collusion with any individual or any
         other organization or party involved in the presentation, defense, or
         settlement of any demand, claim or loss covered under this Agreement.

4.       INDEMNIFICATION OF REINSURED

         (a)   Reinsurer shall indemnify, defend, and hold harmless the
               Reinsured and Reinsured's directors, officers, employees, agents,
               and representatives, for Reinsurer's Quota Share of any demand,
               claim, loss, expense, cost, or liability, including reasonable
               attorney's fees, arising out of or in connection with (1) the
               errors or omissions of Manager, Program Manager, or the Claims
               Handling Facility or (2) Manager, Program Manager or Claims
               Handling Facility following the instructions, directions, or
               procedures of the Reinsurer or Reinsured.

         (b)   In the event of the Program Manager discontinuing the servicing
               of this Program for any reason then Reinsurer agree to pay their
               Quota Share of the ongoing costs for such servicing.

         (c)   Reinsurer will pay their Quota Share of any penalties, fines or
               other regulatory or statutory restitutions imposed on the
               Reinsured by operation of this Agreement.

calculation date. Should the Contingent Commission so calculated be less than
the amount previously paid to the Reinsured, the difference being the Return
Profit Commission shall be due and payable by the Reinsured within 60 days of

ARBITRATION

All disputes arising out of the interpretation, performance or breach of this
Agreement, including the formation or validity thereof, shall be submitted for
decision to a panel of three arbitrators.

One arbitrator shall be chosen by each party and the two arbitrators shall,
before instituting the hearing, choose an impartial third arbitrator who shall
preside at the hearing. If either party fails to appoint its arbitrator within
thirty (30) days after being requested to do so by the other party, the latter,
after ten ( 10) days' notice of its intention to do so, may appoint the second
arbitrator.

If the two arbitrators are unable to agree upon the third arbitrator within
thirty (30) days of their appointment, the third arbitrator shall be selected
from a list of six individuals (three named by each arbitrator), with each
arbitrator eliminating two individuals from the other arbitrator's list, and the
third arbitrator shall be determined by a blind drawing from the two remaining
individuals.

All arbitrators shall be disinterested active or former executive officers of
insurance or reinsurance companies or Underwriters at Lloyd's of London.

Within thirty (30) days after notice of appointment of all arbitrators, the
panel shall meet and determine a schedule for the filing of briefs, discovery
procedures and hearings. The panel shall be relieved of all judicial formality
and shall not be bound by the strict rules of procedure and evidence. Unless the
panel agrees otherwise, arbitration shall take place in Boston, Massachusetts,
but the venue may be changed when deemed by the panel to be in the best interest
of the arbitration proceeding. Insofar as the arbitration panel looks to
substantive law, it shall consider the law of the State of New York. The
decision of any two arbitrators when rendered in writing shall be final and
binding. The panel is empowered to grant interim relief as it may deem
appropriate.

<PAGE>   14

The panel shall make its decision considering the custom and usage of the
applicable insurance and reinsurance business as promptly as possible following
the termination of the hearings. Judgment upon the award may be entered in any
court having jurisdiction thereof.

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 Reinsured to each of the Reinsurers
constituting the one party, provided 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 under the terms of this
Agreement from several to joint.

Each party shall bear the expense of its own arbitrator and shall jointly and
equally bear with the other party the cost of the third arbitrator. The
remaining costs of the arbitration shall be allocated by the panel. The panel
may, at its discretion, award such further costs and expenses as it considers
appropriate, including not limited to attorney's fees.

behalf of Reinsurer in any such suit and/or upon the request of the Reinsured to
give a written undertaking to the Reinsured that they will enter a general
appearance upon Reinsurer's behalf in the event such suit is instituted.

United States which makes provision therefore, Reinsurer hereon hereby
designates the Superintendent, Commissioner or

hereunder arising out of this Agreement, and hereby designate the above named as
the person to whom the said officer is authorized to mail such process or a true
copy thereof.

the obligations of the parties to this Agreement to seek arbitration of any
