ITEM 5.           OTHER EVENTS.

         On August 21, 2003, the Board of Directors of Hercules Incorporated, a
Delaware corporation (the "Company"), approved Amendment No. 2 (the "Amendment")
to the Hercules Incorporated Rights Agreement, dated as of August 4, 2000,
between the Company and Mellon Investor Services LLC, a New Jersey limited
liability company, as Rights Agent (as amended, the "Rights Agreement").

         The Amendment amended the Rights Agreement by changing the expiration
date of the Rights issued thereunder and the "Final Expiration Date," as set
forth in Section 7(a)(i) of the Rights Agreement, to the Close of Business on
September 19, 2003. As a result of the Amendment, the Rights expired, and the
Rights Agreement was terminated, effective as of 5:00 p.m., New York City time,
on September 19, 2003, rather than on August 4, 2010, as originally provided
under the Rights Agreement.

         The foregoing summary of the amendments to the Rights Agreement is not
complete and is qualified in its entirety by reference to the full text of the
Amendment, which is filed as Exhibit 4.1 hereto and is incorporated herein by
reference.
