        <footnote id="F2">Each restricted stock unit is the economic equivalent of one share of Fuel Tech, Inc. Common Stock.</footnote>
        <footnote id="F3">The Restricted Stock Units vest in one installment on the second anniversary of the June 29, 2011 grant date. Generally, shares will be delivered to the reporting person in respect of vested RSUs as soon as practicable after the vesting date, unless the reporting person has elected to defer distribution until a later date.</footnote>
        <footnote id="F4">The Restricted Stock Units vest in three installments from the RSU grant date of March 16, 2012 (&quot;Grant Date&quot;): (i) one-third of the total RSUs awarded shall vest thirteen (13) months after the RSU Grant Date, (ii) one-third shall vest on the second anniversary of the RSU Grant Date, and (iii) the remaining one-third shall vest on the third anniversary of the RSU Grant Date. Generally, shares will be delivered to the reporting person in respect of vested RSUs as soon as practicable after each vesting date, unless the reporting person has elected to defer distribution until a later date.</footnote>
