        <footnote id="F1">This option was previously reported by Mr. Malvaso and is exercisable pro rata on the first, second, third and fourth anniversaries of the 05/29/08 grant date.</footnote>
        <footnote id="F2">This share equivalent unit was granted under the Graham Corporation Outside Directors' Long Term Incentive Plan, as amended.  Under the LTIP, SEUs are credited to each non-employee director's account for each of the first five fiscal years during such director's term in which Graham produces consolidated net income in an amount at least equal to the consolidated net income specified in the budget for each such fiscal year.  Such determinations are made annually.  Each SEU is valued at the market value of one share of common stock on the valuation date, which is the last day of trading of the first quarter following the end of a fiscal year for which SEUs are to be credited.  The number of SEUs to be credited annually is determined by dividing the value of one SEU into $10,000.</footnote>
        <footnote id="F3">Outstanding SEUs accrue dividends quarterly in accordance with Graham's regular dividend policy and such dividends are reflected in each director's account after the end of each fiscal year.  Upon termination of a non-employee director's service, but not before, the non-employee director may redeem each SEU for one share of common stock or, alternatively and subject to Graham's discretion, for the cash equivalent at the closing price of the stock on the NYSE Amex on the date of termination of service, subject to certain limitations.</footnote>
