        <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 of independent directors (as disclosed on page 14 of our 2020 Proxy Statement), and was approved by our Board of Directors at its meeting on May 20, 2020. This year, the recommended and approved stock compensation grant was for shares having a value not to exceed $61,000. 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 20, 2020 was $14.21, resulting in a distribution to each non-management director of 4292 shares.</footnote>
