Explanation of Responses:
( 1)  Represents deferred compensation under the Deferred Compensation Plan for Non-Employee Directors. Each phantom stock unit represents a right to be paid in cash an amount equal to the fair market value of one share of Harsco Corporation Common Stock at the date of settlement. The sheduled settlement for the phantom stock units is following the termination of service as a Director. The deferred compensation credit for fees earned during the quarterly period is the fair market value on the day immediately preceding such credit date. Includes reinvested dividends. The amount credited for each quarterly dividend is payable using the dividend payment date as the valuation date.
( 2)  Represents restricted stock units granted under the 1995 Non-Employee Directors' Stock Plan. Each restricted stock unit has a one-year vesting period and will be settled promptly following termination of the individual's service as a Director of the Company. Includes reinvested dividends.
