        <footnote id="F1">These shares were issued due to the vesting of Restricted Stock Unites on November 24, 2012.  Of the 12,500 shares that vested, 3,825 shares were withheld to pay federal and state taxes.  The recipient received 8,675 shares after taxes.  Since the shares vested on a weekend, the closing stock price of the preceeding day, November 23, 2012, was used per the terms of the 2008 Restricted Stock Unit Plan.  The closing stock price on November 23, 2012 was $8.30 per share.</footnote>
        <footnote id="F2">Each Restricted Stock Unit respresents a contingent right to receive one share of Hallador Energy Company common stock.  The restricted stock units vest three years from the date of the award, April 1, 2015.  If employment terminates prior to vesting, the restricted stock unites shall be immediately cancelled and the reporting person shall cease to  have any right or entitlement to receive any shares under those cancelled units.</footnote>
