     The Program is designed to give eligible participants the opportunity to

     as business unit and individual performance. Incentive bonuses for
     executive officers in the Company's Personal Lines, Commercial Lines and
     Specialty Lines (collectively, "Business Units") will be based 50% on
     corporate operating income and the remaining 50% on their respective
     business unit's combined ratio and premium.  For all other executive
     officers, the incentive will be based on corporate operating income.  A
     copy of the Program is attached hereto as Exhibit 10.1 and hereby
     incorporated by reference.

     Casualty Corporation at an exercise price of $24.55 per share, which was
     the fair market value of the Company's shares as of February 25, 2005.  A
     copy of the agreement is attached hereto as Exhibit 10.2 and hereby
     incorporated by reference.
