WHEREAS, the Company and Swiss Re entered into the Whole Account Net Quota Share

effective January 1, 2004 (hereinafter referred to collectively as the
"Treaty");

WHEREAS, the Company ceded and Swiss Re assumed a 55.0% share in the terms and

(the "2004 Contract Year);

WHEREAS, the Company and Swiss Re have agreed to cancel and commute the 2004
Contract Year as of January 1, 2006, fully and finally settle, commute and

paid under the Treaty (being 55.0% of 3.80% of the 2004 Contract Year Ceded Net
Written Premium). Such amounts shall be deemed to be fully earned premium by
Swiss Re. Further, the Company acknowledges that receipt of such commutation
profit commission constitutes a full and final settlement of all obligations of
Swiss Re to the Company under the 2004 Contract Year, and that no further
amounts are or will be owed to the Company by Swiss Re for the 2004 Contract
Year.

ARTICLE IV - CONFIDENTIALITY AND NONDISCLOSURE

The Company and Swiss Re hereby expressly agree that the terms and conditions of
this Agreement shall be CONFIDENTIAL between Parties and shall not be disclosed
by either Party without the prior written consent of the other, except to the
broker of record of the Treaty, or where required by Order of a court,
administrative tribunal, regulatory body, or arbitration panel. In the event
disclosure is to be made pursuant to this Article, the disclosing Party shall
take all steps necessary to preserve the confidentiality of such information,
including giving prior written notice to the other Party, specifying the
information to be disclosed, the manner of disclosure, and to whom disclosure is

opportunity to oppose such disclosure. Any third party to whom disclosure is
made shall be bound by this Article and shall so state in writing to the Parties
hereto prior to disclosure.

ARTICLE V - GENERAL CONDITIONS

A.   This Agreement is binding on and shall inure to the benefit of all Parties
     hereto and their representative officers, directors, employees, agents,
     attorneys, shareholders, predecessors, parents, affiliates, subsidiaries,
     successors and assigns (including without limitation, any receiver,
     conservator, rehabilitator, liquidator, provisional liquidator, trustee or
     other statutory successor or quasi-statutory successor) upon its execution.

B.   The Parties specifically agree and acknowledge that the consideration for
     the commutation is being paid to the Company in good faith and constitutes
     fair consideration for the discharge of amounts allegedly owing now or
     potentially owing in the future by Swiss Re to the Company for the 2004
     Contract Year.

C.   This Agreement constitutes the entire understanding by and between the
     Parties hereto, superseding all negotiations, prior discussions,
     representations, promises, and understandings, oral or written, expressed
     or implied, made prior to or contemporaneous with its execution. This
     Agreement may only be modified or amended by written agreement, entered
     into subsequent to the date of this commutation and duly executed by the
     Parties hereto.

D.   The failure of the Parties to enforce any provision of this Agreement shall
     not be construed as a waiver of such provision or any other provision of
     this Agreement. No waiver of any provision of this Agreement shall be
     deemed a waiver of any of its other terms, nor shall such waiver constitute
     a continuing waiver.

E.   This Agreement may be executed and delivered in multiple counterparts, each
     of which, when so executed and delivered, shall be an original, but such
     counterparts shall together constitute but one of the same instrument and
     Agreement.

                                                                          (LOGO)
