ARTICLE 14 - ERRORS AND OMISSIONS

statutory successor on the basis of the liability of the Reinsured without
diminution because of the insolvency of the Reinsured or because the liquidator,
receiver, conservator or statutory successor of the Reinsured 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 Reinsured shall give written
notice to the Reinsurer of the pendency of a claim against the Reinsured
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
Reinsured 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 Reinsured 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 Reinsured solely as a result of the defense undertaken
by the Reinsurer.

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 Reinsured.

Contract shall be payable directly by the Reinsurer to the Reinsured or to its
liquidator, receiver, conservator or statutory successor, except as provided by

specifically provides another payee of such reinsurance in the event of the
insolvency of the Reinsured and (b) where the Reinsurerr with the consent of the
direct reinsured or reinsureds has assumed such policy obligations of the
Reinsured as direct obligations of the Reinsurer to the payees under such
policies and in substitution for the obligations of the Reinsured to such
payees.

ARTICLE 17 - ARBITRATION

As a condition precedent to any right of action hereunder, any irreconcilable
dispute between the parties to this Contract will be submitted for decision to a
board of arbitration composed of two arbitrators and an umpire meeting in
Bermuda.

Arbitration shall be initiated by the delivery of a written notice of demand for
arbitration by one party to the other within a reasonable time after the dispute
has arisen.

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, not under the control or management of either party to this Contract.
Each party shall appoint its arbitrator, and the two arbitrators shall choose an
umpire before instituting the hearing. If the respondent fails to appoint its
arbitrator within four (4) weeks after being requested to do so by the claimant,
the latter shall also appoint the second arbitrator. If the two arbitrators fail
to agree upon the appointment of an umpire within four (4) weeks after their
nominations, each of them shall name three of whom the other shall decline two,
and the decision shall be made by drawing lots.

The claimant shall submit its initial brief within forty-five (45) days from
appointment of the umpire. The respondent shall submit its brief within
forty-five (45) days thereafter, and the claimant may submit a reply brief
within thirty (30) days after filing of the respondent's brief.

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 sixty (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 may be entered upon the award of the
board in any court having jurisdiction.

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 clause, and
communications shall be made by the Reinsured to each of the Reinsurers
constituting the one party provided, however, that nothing therein shall impair
the rights of such Reinsurers to assert several

                                     - 6 -

<PAGE>

rather than joint defenses or claims, nor be construed as changing the liability
of the Reinsurers under the terms of this Contract 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 and the remaining
costs of the arbitration proceedings.

ARTICLE 18 - GOVERNING LAW

This Contract shall be governed by and construed in accordance with the laws of
Bermuda.

ARTICLE 19 -  PARTICIPATION

set forth under this Agreement.

The participation of the Reinsurer in the interests and liabilities of this
Agreement shall be separate and apart from the participations of any other
Reinsurers and shall not be joint with those of other Reinsurers, and the
Reinsurer shall in no event participate in the interests and liabilities of any
other Reinsurers.

and/or Employers' Liability) in respect of:

         i)       Nuclear reactors and nuclear power stations or plants;

                  local Nuclear Pool and/or Association but only to the extent
                  of the requirements of the local Pool and/or Association, it
                  being the intention always that Reinsurers shall follow the
                  fortunes of the Company insofar as the Company complies with
                  the requirements of any such local Pool and/or Association.

However, this exclusion shall not apply:

                  a) to any insurance or reinsurance in respect of the
                     construction, erection or installation of buildings, plant
                     and other property (including contractor's plant and
                     equipment used in connection therewith):

         i)       for the storage of nuclear fuel - prior to the commencement of
                  storage;

         ii)      as regards reactor installations - prior to the commencement
                  of loading of nuclear fuel into the reactor, or prior to the
                  initial criticality, depending on the commencement of the
                  insurance or reinsurance of the relevant local Nuclear Pool
                  and/or Association.

                     nor affording coverage in the "high radioactivity" zone.
