Item 2.  Acquisition or Disposition of Assets.

         On April 29, 2002, Hercules Incorporated ("Hercules") announced the
completion of the sale of the Water Treatment Business, consisting of the
BetzDearborn Division and certain Pulp and Paper Division treatment businesses,
to GE Specialty Materials ("GESM"), a unit of General Electric Company.

         The sale price was $1.8 billion in cash, resulting in net after tax
proceeds of approximately $1.665 billion. As previously announced, the Company
used the net proceeds to prepay debt under its senior credit facility and ESOP
credit facility. Pursuant to the March 6, 2002 amendments to the senior credit
facility and the ESOP credit facility, the following provisions became effective
upon the consummation of the sale and the prepayment of debt:

         i.       the release of the subsidiary stock pledged to the collateral
                  agent;

         ii.      the elimination of the requirement that stock of any
                  additional subsidiaries be pledged in the future; and

         iii.     increases in the permitted amounts of asset purchases and
                  dispositions.

         Proceeds from the divestiture will also serve as collateral for
outstanding letters of credit.

                  The following unaudited pro forma consolidated financial
         statements reflect the divestiture of Hercules' Water Treatment

         position of Hercules.
