                      INVESTMENT ADMINISTRATION AGREEMENT

THIS INVESTMENT ADMINISTRATION AGREEMENT (this "Agreement"), dated as of May 11,
2001 and effective as of October 2, 1998, is made by and between FAIRFAX
FINANCIAL HOLDINGS LIMITED and ODYSSEY REINSURANCE CORPORATION. As used in this
Agreement, "we", "us" and "our" shall refer to ODYSSEY REINSURANCE CORPORATION,
and "you" and "your" shall refer to FAIRFAX FINANCIAL HOLDINGS LIMITED.

In consideration of the mutual promises contained herein, the parties agree as
follows:

1.   We authorize you to provide, and by signing below you agree to provide, the
     investment administration services set forth in Schedule A attached hereto,
     on our behalf and on the terms and conditions set out in this Agreement,
     subject to such guidelines, procedures and limitations as may be duly
     established and approved by our Board of Directors or a duly authorized
     committee of said Board.

2.   You shall be entitled to such fees, payable quarterly in arrears, for the
     service provided hereunder, as you may specify from time to time. Attached
     hereto as Schedule B is a copy of your current fee schedule and you agree
     to give us thirty (30) days prior written notice of any change in such
     schedule, which change shall require the approval of the Department. Such
     fees shall be the exclusive fees and charges payable (excluding third party
     disbursements reasonably incurred) for the services provided hereunder. As
     regards third party services, you will charge us only the amount of your
     actual disbursements paid to third parties for such services. We will remit
     payment to you not later than 15 days following delivery to us of a report
     showing the amount due hereunder.

3.   Either party hereto may terminate this Agreement without penalty by giving
     the other party at least thirty (30) days advance written notice of its
     desire to terminate the same.

4.   This Agreement shall enure to the benefit of and shall be binding upon the
     parties hereto and their respective successors. This Agreement may not be
     assigned by either party.

5.   You and we each acknowledge that the terms of this Agreement are the
     exclusive and conclusive terms of our mutual agreement with regard to the
     subject matter hereof.

6.   Any dispute or difference arising with reference to the applicable
     interpretation or effect of this Agreement, or any part thereof, shall be
     referred to a Board of Arbitration (the "Board") or two (2) arbitrators and
     an umpire.

     The members of the Board shall be active or retired disinterested officers
     of insurance or reinsurance companies.

     One arbitrator shall be chosen by the party initiating the arbitration and
     designated in the letter requesting arbitration. The other party shall
     respond, within fifteen (15) days, advising of its arbitrator. The umpire
     shall thereafter be chosen by two (2) arbitrators. In the event either
     party fails to designate its arbitrator as indicated above, the other party
     is hereby authorized and empowered to name the second arbitrator, and the
     party which failed to designate its arbitrator shall be deemed to have
     waived its rights to designate an arbitrator and shall not be aggrieved
     thereby. The two (2) arbitrators shall then have thirty days within which
     to choose an umpire. If they are unable to do so within thirty (30) days
     following their appointment, each arbitrator shall nominate three
     candidates within ten (10) days thereafter, two of whom the other shall
     decline, and the decision shall be made drawing lots. In the event of the
     death, disability or incapacity of an arbitrator or the umpire, a
     replacement shall be named pursuant to the process which resulted in the
     selection of the arbitrator or umpire to be replaced.

     Each party shall submit its case to the Board within one (1) month from the
     date of the appointment of the umpire, but this period of time may be
     extended by unanimous written consent to the Board.

     The sittings of the Board shall take place in Stamford, Connecticut. The
     Board shall make its decision with regards to the custom and usage of the
     insurance and reinsurance business. The Board is released

                                        1

     from all judicial formalities and may abstain from the strict rules of law.
     The written decision of a majority of the Board shall be rendered within
     sixty (60) days following the termination of the Board's hearings, unless
     the parties consent to an extension. Such majority decision of the Board
     shall be final and binding upon the parties both as to law and fact, and
     may not be appealed to any court of any jurisdiction. Judgment may be
     entered upon the final decision of the Board in any court of proper
     jurisdiction.

7.   The provisions in Schedule A and Schedule B attached hereto are hereby
     incorporated into, and form part of, this Agreement.

     hereof, may only be amended by written agreement signed by the parties and
     approved by the Department.
