        <footnote id="F3">Each performance right represents a contingent right to receive between $250,000 and $1 million worth of Hecla Mining Company common stock based on Hecla's TSR performance over the 3-year period relative to our peers, using the average stock price of Hecla and our peers over the last 60 calendar days of 2012 compared to the average stock price of Hecla and our peers over the last 60 calendar days of 2015.  Examples of the potential grant of shares to Mr. Baker under this plan are as follows:  (1) 100th percentile rank among peers = maximum payout at 200% of target (i.e. $1 million worth of common stock); (2) 50th percentile rank among peers = target payout at grant value (i.e. $500,000 worth of common stock); or (3) 25th percentile rank among peers = threshold payout at 50% of target (i.e. $250,000 worth of common stock).</footnote>
