RETROCESSIONAIRE RESERVE DETERMINATION
--------------------------------------

A)       The  Corporation  shall  determine  the  level  of total  reserves  for
         Ultimate Net Loss for the term of this Agreement and shall revise those
         reserves from time to time as  subsequent  events  require.  Should the
         Retrocessionaire  disagree with the reserves  posted by the Corporation
         for the term of this  Agreement,  the  Retrocessionaire  shall select a
         firm, acceptable to the Corporation,  to perform an independent reserve
         analysis.  In  the  event  the  Retrocessionaire   elects  to  have  an
         independent  reserve  analysis  conducted,  the loss settlement date on
         which the Corporation  seeks payment shall be delayed until  completion
         of the analysis, or six months past the loss settlement date, whichever
         first occurs. The results of the independent  reserve analysis shall be
         binding in  establishing  the reserve  amount for this cover until such
         time as a subsequent study is conducted or the Retrocessionaire and the
         Corporation mutually agree to changes in the reserves. The cost of such
         study shall be borne by the Retrocessionaire.

B)       If, subsequent to the  Retrocessionaire  making any payments under this
         Agreement,  the reserves for the term of this  Agreement are decreased,
         either by action of the  Corporation or in accordance  with paragraph A
         of  this   Article,   then  the   Corporation   shall   refund  to  the
         Retrocessionaire  the excess  amount  paid by the  Retrocessionaire  as
         determined using the revised reserves, if any, plus the Interest Credit
         calculated in  accordance  with this  Article.  The Interest  Credit is
         payable  immediately  for the number of days beginning with the date(s)
         such excess amounts were paid by the Retrocessionaire and ending at the
         date the  Retrocessionaire  is  reimbursed  for such excess amount paid
         and/or is paid the Interest Credit due.

C)       The  Interest  Credit  shall be the  average  of the three  month  U.S.
         Treasury Bill rate plus XXX basis points applied against the refund due
         to the Retrocessionaire.

At the option of the  Retrocessionaire,  the accrued Spread shall be paid to the
Retrocessionaire at the end of any quarter in cash or withheld in the Experience
Account.


                                   ARTICLE IX
                                   ----------

LOSS SETTLEMENTS
----------------

The Corporation shall report quarterly to the  Retrocessionaire  the development
of the incurred  Ultimate Net Loss ceded by a report  showing in summary  format
the  percentage  and dollar amount of Ultimate Net Loss for the term, as advised
at  February  1,  1999,  or the  Alternate  Date,  which  has  been  paid by the
Corporation.  At such time as the amount of paid  Ultimate  Net Loss exceeds the
retention  under  this  Agreement,  the  Retrocessionaire  shall  reimburse  the
Corporation  for such paid  Ultimate  Net Loss by payment  within 30 days of the
advice of  amounts  becoming  due.  To the  extent  the  Experience  Account  is
sufficient,  the Retrocessionaire may reimburse the Corporation by consenting to
the  Corporation  retaining for its own account from the Experience  Account the
amount of such paid Ultimate Net Loss.

Notwithstanding the above, the Retrocessionaire  shall have no obligation to pay
any part of any loss which  would cause the  Experience  Account to be less than
the product of negative 30% and the total premium ceded. Nothing set forth above
shall be  construed  as  prohibiting  the  Corporation  from  taking  credit for
Ultimate  Net Loss ceded as the above is only  applicable  to cash  transactions
under this Agreement.

COMMUTATION AND EXPERIENCE REFUND
---------------------------------

This  Agreement  may be commuted at the  Corporation's  sole option by giving 90
days  advance  written  notice  at any time of its  intent to so  commute  after
expiration of the term.

If at the time of  commutation  the amount of unpaid  Ultimate  Net Loss is less
than or equal to the Experience Account Balance, the Retrocessionaire  agrees to
pay all unpaid Ultimate Net Loss as of the date of commutation.

If at the time of commutation  the amount of unpaid Ultimate Net Loss is greater
than the  Experience  Account  Balance,  the unpaid  Ultimate  Net Loss shall be
commuted at an amount to be mutually agreed. If mutual agreement is not reached,
then no commutation shall be permitted.

In the event that unpaid  Ultimate  Net Loss is commuted,  the  Retrocessionaire
agrees to pay an  experience  refund equal to the positive  difference,  if any,
between the Experience Account Balance after deduction of the accrued Spread due
the  Retrocessionaire,  if any, which shall be paid to the  Retrocessionaire  at
that time, and the commuted value of unpaid  Ultimate Net Loss.  Such payment of
an experience  refund shall be made by the  Corporation's  retention for its own
account from the Experience Account.

Payment by the Retrocessionaire of the commuted unpaid Ultimate Net Loss and the
experience  refund, if any, shall constitute a complete and final release of the
Retrocessionaire in respect of its obligations under this Agreement.

Any amount due to the  Corporation  as calculated  above shall be payable by the
Retrocessionaire within 30 days following the date of commutation.


                                   ARTICLE XI

COMMUTATION APPROVAL ON CORPORATION'S POLICIES
----------------------------------------------

In the event of a commutation of any Policy resulting in the payment of Ultimate
Net  Loss  in  excess  of  $X,XXX,XXX  prior  to the  time  required  under  the
Corporation's  Policies for the term of this  Agreement,  then the paid Ultimate
Net Loss under this  Agreement  shall be  determined as if such  commutation  or
other arrangement had not occurred.  The analysis to determine both the ultimate
reserve  amount and the payout  pattern  which would have occurred on a commuted
Policy shall, unless waived in writing by the  Retrocessionaire,  be made on the
basis of an independent  reserve analysis.  The  Retrocessionaire  will select a
firm acceptable to the Corporation to conduct the analysis. The Retrocessionaire
shall bear the cost of such analysis and the results of such  analysis  shall be
binding in  determining  the ultimate  reserve amount and payout pattern for the
commuted reinsurance contract.

(This article applies only to property insurance and reinsurance.)

If this Agreement expires while an occurrence  covered hereunder is in progress,
the Retrocessionaire's liability hereunder shall, subject to the other terms and
conditions of this  Agreement,  be determined  as if the entire  occurrence  had
taken place prior to the expiration of this Agreement,  provided that no part of
such occurrence is claimed against any renewal or replacement of this Agreement.

All  aggregate  Policies  coming  within  the scope of this  Agreement  shall be
covered on a risks  attaching  basis  rather  than on an  occurrence  basis.  An

as  attaching  at each  anniversary  date of such Policy while such Policy is in
force.

shall not be  unreasonably  withheld by the  Retrocessionaire.  The  Corporation
specifically  warrants  that it will not change its gross line guide nor inuring
protections without prior advice to and approval from the Retrocessionaire,  and
such approval shall not be unreasonably withheld by the Retrocessionaire.

ERRORS AND OMISSIONS

Any inadvertent delays,  omissions or errors 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,  and does not impose any greater  liability
upon the other party than would have attached  hereunder if the delay,  omission
or error had not occurred.

TAXES
-----

In  consideration  of the terms under which this  Agreement is entered into, the
Corporation  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,
and the  Corporation  will be liable for payment of all premium taxes on premium
ceded under this Agreement.

OFFSET
------

The  Corporation  and the  Retrocessionaire  shall  have the right to offset any
balance(s) due from one to the other under this  Agreement.  The party asserting
the right of offset may exercise such right any time whether the  balance(s) due
are on  account  of  premiums  or  losses  or  otherwise.  In the  event  of the
insolvency  of a party hereto,  offset shall only be allowed in accordance  with
the provision of Section 7427 of the Insurance Law of the State of New York.


                                   ARTICLE XX
                                   ----------

INSOLVENCY
----------

In the event of the insolvency of the Corporation,  the retrocession  under this
Agreement  shall be payable  directly to the  Corporation or to its  liquidator,
receiver,  conservator  or statutory  successor on the basis of the liability of
the Corporation  without diminution because of the insolvency of the Corporation
or because the liquidator,  receiver,  conservator or statutory successor of the
Corporation  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  Corporation  shall  give  written  notice  to the  Retrocessionaire  of the
pendency of a claim  against the  Corporation  indicating  the Policy  reinsured
which  claim   would   involve  a  possible   liability   on  the  part  of  the
Retrocessionaire  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

INSOLVENCY (continued)
----------------------

Retrocessionaire  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  Corporation  or its  liquidator,  receiver,
conservator   or  statutory   successor.   The  expense  thus  incurred  by  the
Retrocessionaire  shall be  chargeable,  subject to the  approval  of the Court,
against the  Corporation as part of the expenses of  conservation or liquidation
to the  extent  of a pro rata  share of the  benefit  which  may  accrue  to the
Corporation   solely   as  a   result   of  the   defense   undertaken   by  the
Retrocessionaire.

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

It is further  understood and agreed that, in the event of the insolvency of the
Corporation,  the retrocession under this Agreement shall be payable directly by
the  Retrocessionaire  to  the  Corporation  or  to  its  liquidator,  receiver,
conservator or statutory successor, except as provided by Section 4118(a) of the
New York Insurance Law or except (a) where the Agreement  specifically  provides
another  payee  of such  retrocession  in the  event  of the  insolvency  of the
Corporation  and (b) where the  Retrocessionaire  with the consent of the direct
Insured or Insureds has assumed such Policy  obligations  of the  Corporation as
direct obligations of the Retrocessionaire to the payees under such Policies and
in substitution for the obligations of the Corporation to such payees.


                                   ARTICLE XXI
                                   -----------

ARBITRATION
-----------

As a condition  precedent to any right of action hereunder,  any dispute arising
out of  this  Agreement  shall  be  submitted  to the  decision  of a  board  of
arbitration composed of two arbitrators and an umpire, meeting in Overland Park,
Kansas,   unless   otherwise   mutually   agreed  by  the  Corporation  and  the
Retrocessionaire.

The members of the board of arbitration shall be active or retired disinterested
officials of insurance or reinsurance  companies,  or  underwriters  at Lloyd's,
London.  Each party shall appoint its arbitrator and the two  arbitrators  shall
choose an umpire before instituting the hearing.  In the event that either party
should fail to choose an arbitrator  within 30 days following a written  request
by the other party to enter upon  arbitration,  the requesting  party may choose
two  arbitrators  who  shall in turn  choose  an  umpire  before  entering  upon
arbitration.  In the event the two arbitrators fail to agree on an umpire either
party  shall  have the right to submit the  matter to the  American  Arbitration
Association  in effect at that  time to name an  umpire in  accordance  with the
qualifications provided hereinabove.

ARBITRATION (continued)
-----------------------

Each party shall present its case to the  arbitrators  within 60 days  following
the date of their appointment.  The board shall make its decision with regard to
the custom and usage of the insurance and reinsurance business.  The board shall
issue its  decision  in writing  based upon a hearing in which  evidence  may be
introduced  without  following  strict  rules of  evidence  but in  which  cross
examination  and  rebuttal  shall be allowed.  The board shall make its decision
within 60 days  following  the  termination  of the hearings  unless the parties
consent to an extension.  The majority  decision of the board shall be final and
binding upon all parties to the proceeding.  Judgment upon the final decision of
the board may be entered in any court of competent jurisdiction.

If more than one  Retrocessionaire  is  involved in the same  dispute,  all such
Retrocessionaires  shall  constitute  and act as one party for  purposes of this
Article  and  communications  shall  be made by the  Corporation  to each of the
Retrocessionaires  constituting the one party,  provided,  however, that nothing
shall impair the rights of such Retrocessionaires to assert several, rather than
joint,  defenses or claims,  nor be construed  as changing the  liability of the
Retrocessionaires 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 expense of the umpire.  In the event both
arbitrators  are chosen by one party,  the  expense of the  arbitrators  and the
umpire shall be jointly and equally  borne  between the parties.  The  remaining
costs of the arbitration proceedings shall be allocated by the board.

This Article shall survive the termination of this Agreement.

NONWAIVER
---------

The failure of the Corporation or the  Retrocessionaire  to insist on compliance
with this  Agreement  or to  exercise  any right or remedy  hereunder  shall not
constitute a waiver of any rights or remedies  contained herein, nor stop either
party from thereafter  demanding full and complete compliance nor prevent either
party from exercising such rights or remedies in the future.
