     Commentary on Results from Continuing Operations

     --   Favorable net reserve development from prior accident years was $13.0
          million in the quarter and $23.0 million for 2005.

     --   In 2005 our policies renewed at rates that were, on average, 11%
          higher than expiring.

     --   Policyholder retention for the year was 85%, which met our
          expectations in the 2005 pricing environment given our philosophy of
          continuous re-underwriting and dedication to rate adequacy.

     --   Policyholder count increased by approximately seven percent
          year-over-year primarily due to the acquisition of NCRIC, as well as
          new business in targeted growth states.

     --   Our reinsurance program renewed with no change in pricing or
          conditions on October 1, 2005. NCRIC's reinsurance contracts expired
          January 1, 2006 and NCRIC was brought into our existing reinsurance
          program on that date.

          expected;

          longer to realize than expected;
