Explanation of Responses:

( 1 )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 15 of our 2019 Proxy Statement), and was approved by our Board of Directors at its meeting on May 22, 2019. 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 22, 2019 was $38.65, resulting in a distribution to each non-management director of 1,578 shares. ( 2 )RSU's are equal in value to one share of Common Stock, issued on 10/5/17 under the 2014 Equity Incentive Plan and acquired under terms of the ProAssurance Corporation 2011 Employee Stock Ownership Plan. The RSUs vest upon the sooner of three years of continuous employment, termination of employment by reason of death or disability, for "good reason," or a change of control of the Company. If a participant terminates employment more than twelve months but less than three years from the date of grant, the RSUs will partially vest based on the number of days that the participant was employed in the vesting period. Any RSUs that are unvested on termination of employment will be forfeited. In addition, if a participant withdraws shares purchased for his or her account, matching unvested RSUs will be forfeited. Upon vesting, we will pay the RSUs in shares of our Common Stock from those shares reserved for issuance under the 2014 Equity Incentive Plan with the value established at vesting. ( 3 )RSU's are equal in value to one share of Common Stock, issued on 10/5/16 under the 2014 Equity Incentive Plan and acquired under terms of the ProAssurance Corporation 2011 Employee Stock Ownership Plan. The RSUs vest upon the sooner of three years of continuous employment, termination of employment by reason of death or disability, for "good reason," or a change of control of the Company. If a participant terminates employment more than twelve months but less than three years from the date of grant, the RSUs will partially vest based on the number of days that the participant was employed in the vesting period. Any RSUs that are unvested on termination of employment will be forfeited. In addition, if a participant withdraws shares purchased for his or her account, matching unvested RSUs will be forfeited. Upon vesting, we will pay the RSUs in shares of our Common Stock from those shares reserved for issuance under the 2014 Equity Incentive Plan with the value established at vesting.
