premiums will continue to grow with the successful completion of its
transaction with Physicians Insurance Company of Wisconsin, Inc. (PIC
Wisconsin) on August 1, 2006.

        Flow) was affected by a $50 million investment in a portfolio
        of trading securities in the second quarter of 2006. While
        this is part of our investing strategy, accounting standards

        provided Cash Flow of $31 million.

1,991,481 shares of ProAssurance stock to current PIC Wisconsin
shareholders. Each PIC Wisconsin shareholder will receive 102.75
