A                         The term “Ultimate Net Loss” shall mean the actual sum
paid by the Company in settlement of losses or liability including interest
accrued prior to judgment after making deductions for all recoveries, including
subrogation, salvages, and claims upon other reinsurances, whether collectible
or not, which inure to the benefit of the Reinsurer under this Agreement, and
shall exclude all expenses incurred by the Company; provided, however, that in
the event of the insolvency of the Company, Ultimate Net Loss shall mean the
amount of loss for which the Company is liable, and payment by the Reinsurer

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

Company’s Ultimate Net Loss. The Reinsurer shall not be liable for any portion
of the Company’s Loss Adjustment Expenses, unless the Company’s Ultimate Net
Loss exceeds its retention.

D                          In the event a verdict, award or judgment is
ultimately compromised, reduced or reversed on appeal, the Reinsurer shall
indemnify the Company for the Loss Adjustment Expenses incurred in obtaining
such reduction or reversal in the ratio that the benefit each party derives from
such reduction, reversal or compromise bears to the total benefit derived
therefrom. However, all Loss Adjustment Expenses incurred up to the time of the
original verdict or judgment shall be considered separate and apart from appeal
expenses and shall be prorated in proportion to each party’s interests in such
original verdict or judgment.

E.                         The term “Loss Adjustment Expenses” shall mean all
expenses incurred by the Company in connection with the investigation,
settlement, defense or litigation, including court costs and post-judgment
interest, of any claim or loss covered by the Policies reinsured under this
Agreement, but shall exclude the salaries and expenses of Company employees,
office expenses, Declaratory Judgment Expenses and other overhead expenses.

F                            The term “Declaratory Judgment Expenses” shall mean
all legal expenses, incurred in the representation of the Company in litigation
brought to determine the Company’s defense and/or indemnification obligations.

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

H.                       Nothing in this Article shall be construed to mean that
losses are not recoverable hereunder until the Ultimate Net Loss of the Company
has been ascertained.

ARTICLE VI - LOSS IN EXCESS OF POLICY LIMITS

A                         “Loss in Excess of Policy Limits” is defined as loss
in excess of the limit of the original Policy, such loss in excess of the limit
having been incurred because of failure by the Company to settle within the
Policy, limit or by reason of 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 action.

4

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

B                           However, this Article shall not apply where the loss
has been incurred due to fraud by a member of the Board of Directors or a
corporate officer 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.

C                           For the purposes of this Article, the word “loss”
shall mean any amounts which the Company would have been contractually liable to
pay had it not been for the limit of the original Policy.

D                          With respect to coverage provided under this Article,
recoveries from any insurance or reinsurance other than this Agreement, whether
collectible or not, shall be deducted to arrive at the amount of the Company’s
Ultimate Net Loss.

ARTICLE VII - EXTRA CONTRACTUAL OBLIGATIONS

A                         “Extra Contractual Obligations” are defined as those
liabilities not covered under any other provision of this Agreement and which
arise from the handling of any claim on business covered hereunder, such
liabilities arising because of, but not limited to, the following: failure by
the Company to settle within the Policy limit, or by reason of 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 action.

B                           The date on which an Extra Contractual Obligation is
incurred by the Company shall be deemed, in all circumstances, to be the data of
the original accident, casualty, disaster or loss occurrence.

C                           However, coverage hereunder as respects Extra
Contractual Obligations shall not apply where the loss has been incurred due to
the fraud of a member of the Board of Directors or a corporate officer 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.

D                          Recoveries, collectible or retention from any other
form of insurance or reinsurance including deductibles or self-insured retention
which protect the Company against Extra Contractual Obligations, whether
collectible or not, shall inure to the benefit of the Reinsurer and shall be
deducted from the total amount of Extra contractual obligation for purposes of
determining the loss hereunder.

5

E                            If any provision of this Article shall be rendered
illegal or unenforceable by the laws, regulations or public policy of any state,

Adjustment Expenses paid less recoveries, including salvage and subrogation,
during the current Period as respects losses which occurred during the period

deficit.

which:

1                            Are reserved by the Company for an amount in excess
of 50% of its retention;

2                            Originate from fatal injuries;

3                            Originate from the following kinds of bodily

cooperate in every respect in the defense of any such claim, suit or proceeding.

ARTICLE XV - SALVAGE AND SUBROGATION

A                         In the event of the payment of any indemnity by the
Reinsurer under this Agreement, the Reinsurer shall be subrogated, to the extent
of such payment, to all of the rights of the Company against any person or
entity legally responsible for damages of the loss. The Company agrees to
enforce such rights; but, in case the Company refuses or neglects to do so, the
Reinsurer is hereby authorized and empowered to bring any appropriate action in
the name of the Company or their policyholders or otherwise to enforce such
rights.

B                           From any amount recovered by subrogation, salvage or
other means, there shall first be deducted the expenses incurred in effecting
the recovery. The balance shall then be used to reimburse the excess carriers in
the inverse order to that in which their respective liabilities attached, before
being used to reimburse the Company for its primary loss.

12

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

ARTICLE XVI - ACCESS TO RECORDS

The Reinsurer or its duly authorized representatives shall have the right to
examine, at the offices of the Company at a reasonable time, during the currency

ARTICLE XVII - TAXES

The Company shall be liable for all taxes on premiums paid to the Reinsurer

Wherever the word “dollars” or the “$” symbol is used in this Agreement, it
shall mean dollars of the United States of America, excepting in those cases
where the Policy is issued by the Company in Canadian dollars, in which case it
shall mean dollars of Canada. In the event the Company is involved in a loss
requiring payment in United States and Canadian currency, the Company’s
retention and the limit of liability of the Reinsurer shall be apportioned
between the two currencies in the same proportion as the amount of net loss in
each currency bears to the total amount of net loss paid by the Company. For the
purposes of this Agreement, where the Company receives premiums or pays losses
in currencies other than United States or Canadian currency, such premiums and
losses shall be converted into United States dollars at the actual rates of
exchange at which the premiums and losses are entered in the Company’s books.

ARTICLE XIX - OFFSET

Each party to this Agreement together with their successors or assigns shall
have and may exercise, at any time, the right to offset any balance or balances
due the other (or, if more than one, any other). Such offset may include
balances due under this Agreement and any other agreements heretofore or
hereafter entered into between the parties regardless of whether such balances
arise from premiums, losses or otherwise, and regardless of capacity of any
party, whether as assuming insurer and/or coding insurer, under the various
agreements involved, provided however, that in the event of insolvency of a
party hereto, offsets shall only be allowed in accordance with the provisions of
Section 7427 of the Insurance Law of the State of New York to the extent such
statute or any other applicable law, statute or regulation governing such offset
shall apply.

13

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

ARTICLE XX - ERRORS OR OMISSIONS

Errors or omissions of an administrative nature on the part of the Company shall
not invalidate the reinsurance under this Agreement, provided such errors or
omissions are corrected promptly after discovery thereof; but the liability of
the Reinsurer under this Agreement or any exhibits, addenda, or endorsement
attached hereto shall in no event exceed the limits specified herein nor be
extended to cover any risks, perils, lines of business or classes of insurance
generally or specifically excluded herein.

ARTICLE XXI - DISPUTE RESOLUTION

Part I - Choice Of Law And Forum

Any dispute arising under this Agreement shall be resolved in the Commonwealth
of Massachusetts, and the laws of the State of Commonwealth of Massachusetts
shall govern the interpretation and application of this Agreement.

Part II - Mediation

If a dispute between the Company and the Reinsurer, arising out of the
provisions of this Agreement or concerning its interpretation or validity and
whether arising before or after termination of this Agreement has not been
settled through negotiation, both parties agree to try in good faith to settle
such dispute by nonbinding mediation, before resorting to arbitration.

Part III - Arbitration

A.                      Resolution of Disputes - As a condition precedent to any
right of action arising hereunder, any dispute not resolved by mediation between
the Company and the Reinsurer arising out of the provisions of this Agreement or

arbitrate, all disputes shall be submitted to an arbitration panel composed of
two arbitrators and an umpire chosen in accordance with Paragraph C. hereof.

C.                        Appointment of Arbitrators - The members of the

other party (hereinafter referred to as the “respondent”) together with its
notice of intention to arbitrate. Within 30 days after receiving such notice,
the respondent shall also appoint an arbitrator and notify the claimant thereof
by certified mail. Before instituting a hearing, the two arbitrators so
appointed shall choose an umpire. If, within 20 days after the appointment of
the arbitrator chosen by the respondent, the two arbitrators fail to agree upon

extended by the arbitration panel or agreed to by the parties, each party shall
submit its case to the panel within 30 days after the selection of the umpire.

F.                         Procedure Governing Arbitration - All proceedings
before the panel shall be informal and the panel shall not be bound by the
formal rules of evidence. The panel shall have the power to fix all procedural
rules relating to the arbitration proceedings. In reaching any decision, the
panel shall give due consideration to the customs and usages of the insurance
and reinsurance business.

G.                        Arbitration Award - The arbitration panel shall render
its decision within 60 days after termination of the proceeding, which decision
shall be in writing, stating the reasons therefor. The decision of the majority
of the panel shall be final and binding on the parties to the proceeding. In no
event, however, will the panel be authorized to award punitive, exemplary or
consequential damages of whatsoever nature in connection with any arbitration
proceeding concerning this Agreement.

H.                       Cost of Arbitration - Unless otherwise allocated by the
panel, each party shall bear the expense of its own arbitrator and shall jointly
and equally bear with the other parties the expense of the umpire and the
arbitration.

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

ARTICLE XXII - INSOLVENCY

A                         In the event of insolvency of the Company, the
reinsurance provided by this Agreement shall be payable by the Reinsurer on the
basis of the liability of the Company as respects Policies covered hereunder,
without diminution because of such insolvency, directly to the Company or its
liquidator, receiver, conservator or statutory successor except as provided in
Sections 4118 (a) (1) (A) and 1114 (c) of the New York Insurance Law.

B                           The Reinsurer shall be given written notice of the
pendency of each claim or loss which may involve the reinsurance provided by
this Agreement within a reasonable time after such claim or loss is filed in the
insolvency proceedings. The Reinsurer shall have the right to investigate each
such claim or loss and interpose, at its own expense, in the proceedings where
the claim or loss is to be adjudicated, any defense which it may deem available
to the Company, its liquidator, receiver, conservator or statutory successor.
The expense thus incurred by the Reinsurer shall be chargeable, subject to court
approval, against the insolvent Company as part of the expense of liquidation to
the extent of a proportionate share of the benefit which may accrue to the
Company solely as a result of the defense undertaken by the Reinsurer.

C                           In addition to the offset provisions set forth in
Article XVIII Offset, any debts or credits, liquidated or unliquidated, in favor
of or against either party on the date of the receivership or liquidation order
(except where the obligation was purchased by or transferred to be used as an
offset) are deemed mutual debts or credits and shall be set off with the balance
only to be allowed or paid. Although such claim on the part of either party
against the other may be unliquidated or undetermined in amount of the date of
entry of the receivership or liquidation order, such claim will be regarded as
being in existence as of such date and any claims then in existence and held by
the other party may be offset against it.

D                          Nothing contained in this Article is intended to
change the relationship or status of the parties to this Agreement or to enlarge
upon the rights or obligations of either party hereunder except as provided
herein.

ARTICLE XXIII - SPECIAL TERMINATION

calendar year. Such reduction shall be determined by calculating the difference
between the Company’s prior year annual statement and each subsequent quarterly
statutory statement within such current calendar year.

As respects the event set forth in this Paragraph A.4., the Company shall be
obligated to notify the Reinsurer in writing within 30 days after the filing of
its quarterly statement. Upon receipt of such notification the Reinsurer shall
have the right to terminate this Agreement, by giving not less than 30 days
