On January 24, 2006, the Company's Board of Directors approved an award of
performance-based restricted stock units to five of the Company's executive
officers and certain other officers of the Company. Pursuant to such approval,
the Company granted the following restricted stock units to the following
executive officers of the Company:

                                    Number of Restricted      Fair Market Value 
            Name                         Stock Units               01-24-06
            ----                         -----------               --------

     Geoffrey D. H. Butler               5,000 units              $ 357,550
     President & CEO MultiServ and
     SGB Groups

     Salvatore D. Fazzolari              5,000 units              $ 357,550
     President, Chief Financial
     Officer & Treasurer

     Mark E. Kimmel                      1,350 units              $  96,539
     General Counsel &
     Corporate Secretary

     Richard C. Neuffer                  2,500 units              $ 178,775
     Group President

     Vice President & Controller

The awards, which vest after three years of continuous employment, were made
pursuant to the terms of the Company's 1995 Executive Incentive Compensation
Plan. The form of the award agreement is attached to this filing as Exhibit 10
and is incorporated herein by reference.

In addition, the Board approved a cash payment to Derek C. Hathaway, the
Company's Chairman and Chief Executive Officer. This payment was in lieu of the
restricted stock units award that was made to other officers of the Company as
noted above. The Board took into account Mr. Hathaway's present stock holdings
and outstanding stock options in the Company and the stage of his career at
Harsco, and determined that it was appropriate to award him cash in lieu of the
restricted stock units. Mr. Hathaway's cash payment was equal to $715,100 and
was based on the average of the high and the low sales price (Fair Market Value
as defined by the Executive Incentive Compensation Plan) of the Company's common
stock on January 24, 2006 and 10,000 shares.
