Item 5.      Other Events and Regulation FD Disclosure.
             -----------------------------------------

         On March 17, 2003, W. R. Grace & Co. ("Grace") notified participants in
its Savings and Investment Plan, a plan qualified under section 401(k) of the
Internal Revenue Code (the "Plan"), of changes in the operation of the Grace
common stock funds. In recognition that the value of Grace common stock is more
likely to be affected by speculation as Grace progresses toward a plan of
reorganization in its Chapter 11 proceeding, commencing on April 21, 2003,
participants will no longer be permitted to contribute to, or make transfers
from other funds into, the Grace common stock funds. Participants in the Plan
will continue to be able to transfer existing balances out of the Grace common
stock funds into the other available investment funds offered by the Plan. The
letter to participants is filed as an exhibit hereto and is incorporated by
reference herein.
