        <footnote id="F1">These shares are awarded under the ProAssurance Corporation Director Deferred Stock Compensation Plan and are exempt under Rule 16b-3. This grant was recommended by the Compensation Committee, which is composed entirely independent directors (as disclosed on page 17 of our 2014 Proxy Statement), and was approved by our Board of Directors at its meeting on May 28, 2014. This year, the recommended and approved stock compensation grant was for shares having a value not to exceed $56,000. The number of whole shares is determined using the closing price of a share of stock on the New York Stock Exchange (NYSE) on the day of the Board of Directors meeting following the Annual Meeting of Shareholders. The NYSE closing price on May 28, 2014 was $44.80, resulting in a distribution to each non-management director of 1,250 shares.</footnote>
        <footnote id="F2">Shares acquired from ProAssurance Corporation under its Director Deferred Stock Compensation Plan which are exempt under Rule 16b-3. The plan was amended in 2013 to provide that dividends accumulated on deferred stock will be invested in shares of our stock and paid solely in our shares of stock when the deferred stock is payable to the directors. Only whole shares are purchased and remaining cash remains in the non-management director's deferred account for future purchase. Any future purchases of this nature will be made yearly, on the date of the Annual Meeting of Shareholders, under the same terms and conditions set forth in this footnote.</footnote>
