              GRACE RECEIVES $57 MILLION FROM INSURANCE SETTLEMENT

                        DAREX STRATEGIC REVIEW COMPLETED

             CEO ANNOUNCES NEW PRODUCTIVITY AND GROWTH INITIATIVES

         BOCA RATON, Florida, November 23, 1998 -- W. R. Grace & Co. (NYSE:
GRA) announced today that it has entered into a settlement with one of its
insurance carriers which provides for a $57 million lump-sum cash payment to
Grace for previously incurred costs related to environmental remediation. The
cash payment, which was received last week, will be recorded as income in the
fourth quarter.

DAREX CONTAINER PRODUCTS
- ------------------------

         The company also announced that it had completed its strategic review
of the Darex Container Products business and that the business will remain
within Grace. Remarked Grace President and Chief Executive Officer Paul J.
Norris, "The Darex business has some excellent growth opportunities coming out
of the R&D pipeline. Despite the recent market difficulties this business has
faced, I am convinced that developing and commercializing the new oxygen
scavenging products is the best course of action for Grace shareholders at this
time. In addition, the Darex team is working now on identifying further cost
savings programs to restore near-term profitability growth."

NEW PRODUCTIVITY AND GROWTH INITIATIVES
- ---------------------------------------

         Norris also announced new initiatives to continue to increase Grace
shareholder value, saying, "We are conducting a company-wide review of various
administrative and operating functions to identify productivity improvements.
We will also immediately begin an intensive strategic review to identify growth
opportunities for the company, both internal and through acquisition."

         The company indicated that, in light of its strategic growth review,
it will repurchase shares from time to time as market conditions permit, rather
than at the aggressive pace previously indicated. The company has repurchased
approximately 4.9 million shares under this program since it began in April.

OTHER DEVELOPMENTS
- ------------------

         Grace reported that it has not yet identified a buyer or strategic
partner for the Circe Biomedical operation. Grace is continuing discussions
with potential buyers and partners, but if it is unable to make appropriate
arrangements, the operation will be shut down. Costs of shutdown will be
included in the fourth quarter, after which the company expects to report no
material further costs associated with the project.

         Grace has completed its review of the possibility of obtaining
high-level asbestos-related insurance coverage and has determined not to
acquire such insurance coverage at this time. Based on recent favorable trends
in new personal injury claims received, the company believes that purchasing
insurance is not currently in shareholders' best interests.

         Grace's accounting policy for asbestos liabilities continues to be to
accrue for the estimated cost of defending and disposing of all pending
property damage and personal injury claims as well as the cost of personal
injury claims expected to be filed in the coming five years. The company
reviews the adequacy of this accrual, and the need to replenish it, every
quarter.

1998 FOURTH QUARTER

         Grace also stated that it expects to take a number of non-recurring
charges in the fourth quarter. These charges, the amounts of which are not yet
finalized, will cover expected additional costs to remediate environmental
issues on a Grace site and other matters, including Circe shutdown costs and
any asbestos-related reserve replenishment. In aggregate, management estimates
that these charges could be in the range of $50 million.

         Additionally, Grace indicated that the administrative and operating
productivity review, along with the Darex cost savings study, may also result
in fourth quarter charges.

         Commenting on the announcements, Norris said, "We have come to
decisions on several important strategic matters and now look forward to
driving growth and profitability in all our businesses. I am enthusiastic about
Grace's prospects in the near and long term. We will use productivity
improvements to continue to drive earnings short term, while identifying
additional sources of growth for the long term."

         Grace is a leading global supplier of catalysts and silica products,
specialty construction chemicals and building materials, and container sealants
and closure systems. With annual sales of approximately $1.5 billion, Grace has
6,300 employees and operations in nearly 40 countries.
