                                 CURRENT REPORT

Item 8.01         Other Events.
                  ------------

         On June 1, 2005, the New Jersey Department of Environmental Protection
("DEP") filed a lawsuit against W. R. Grace & Co., W. R. Grace & Co.-Conn.
(collectively "Grace") and two employees, seeking civil penalties for alleged
misrepresentations and false statements made in a Preliminary Assessment/Site
Investigation Report and Negative Declarations submitted by Grace to the DEP in
1995 pursuant to the New Jersey Industrial Site Recovery Act. Grace submitted
the Report, which was prepared by an independent environmental consultant, in
connection with the closing of Grace's former plant in Hamilton Township, New
Jersey.

            Grace purchased the Hamilton plant in 1963 and ceased operations
there in 1994. During this period, Grace produced spray-on fire protection
products and vermiculite-based products at the plant.

            Grace is unable at this time to assess the effect of the lawsuit on
Grace's results of operations or financial condition, or on its bankruptcy
proceeding.
