                                                            March 1, 1995


Mr. Jean-Louis Greze
Executive Vice President
W. R. Grace & Co.
One Town Center Road
Boca Raton, FL 33486-1010

Dear Jean-Louis:

      This letter describes certain arrangements that will apply to you during
and after your current assignment as Executive Vice President, W. R. Grace & Co.
and President, Grace Packaging.  During that assignment, you will be an employee
of W. R. Grace & Co. or one of its subsidiaries or affiliates (collectively
referred to herein as the "Company") and be based at Grace Headquarters in Boca
Raton, Florida.

      I.    ALLOWANCES.  During your assignment, the Company will provide you
with the following allowances:

            SCHOOL FEES.   The Company will continue to pay tuition and related
            fees associated with the education of your son, up to but not
            inclusive of college.

            HOME LEAVE.  The Company will reimburse you for the cost of one
            roundtrip Business Class flight per calendar year between Florida
            and Switzerland for your wife and son.

            COMPANY CAR.  You will be provided with a Company-leased car in
            accordance with the policy applicable to Grace Headquarters
            executives.

            HOUSING LOAN.  The Company has provided you with a $400,000 non-
            interest-bearing loan to assist you in the purchase of a house in
            Florida that will be your principal residence during the assignment,
            such loan to

            be secured by a mortgage on the house.  You have agreed
            to repay that loan upon your retirement or other termination of
            service with the Company.


      II.   REPATRIATION.  At the end of your current assignment, which is
targeted to be on or about August 1, 1996, the Company will provide you with the
following relocation assistance should you and your family wish to be
repatriated to Switzerland at that time:

            COST OF MOVE.  The Company will reimburse you for the cost of
            Business Class air fare and incidental expenses related to the
            relocation of you and your immediate family back to Switzerland.

            The Company will pay for the packing, transporting, unpacking and
            insurance of all your household effects from Florida to Switzerland,
            provided that moving your household effects is coordinated through
            the Grace International Human Resources Department, using a moving
            company designated by that Department.

            SALE OF RESIDENCE.  Grace will offer to purchase your Florida
            residence for its Fair Market Value ("FMV"), established as
            described in this paragraph.  The FMV of your Florida residence will
            be established by securing and averaging two appraisals made by
            professional appraisers selected by the International Human
            Resources Department.  If the appraisals vary by five (5) percent or
            more, a third appraisal will be obtained, and the average of the two
            closer appraisals will be the FMV of your Florida residence.

            From the date the Company notifies you in writing of the FMV of your
            Florida residence, you will have sixty (60) days to accept, in
            writing to the International Human Resources Department, the
            Company's offer to purchase your residence at the FMV.  You may,
            instead,  elect to reject that offer and sell your residence without
            assistance from the Company, in which case the Company will be under
            no obligation to reimburse you for a sale price below the FMV or for
            maintenance or carrying expenses.

            Failure to accept, in writing, the established FMV within the 60-day
            period described above will be deemed a rejection of the Company's
            offer to purchase the residence at FMV.

            Should you sell your Florida residence without the assistance of the
            Company, the Company will nevertheless reimburse you for reasonable
            and documented expenses that are incidental to the sale, such as any
            real estate commission, attorney's fees (or bank service fees if in
            lieu of attorney's fees), penalties for mortgage prepayment, revenue
            stamps, recording or discharge of mortgage, transfer taxes, title
            evidence based on local practice, and advertising expenses if no
            real estate commission is involved.


      III.  PENSION.

            During your current assignment, you will continue to participate in
            the Company's  Swiss Pension Plan until July 31, 1996 or your
            termination of service, if earlier.  Your final average salary for
            purposes of determining your benefits under that plan will be based
            on the following notional salary schedule:

                          AMOUNT                 EFFECTIVE

                       SFr. 555,000           January 1, 1990
                       SFr. 600,000           July 1, 1991
                       SFr. 645,000           January 1, 1993
                       SFr. 695,000           July 1, 1994
                       SFr. 745,000           January 1, 1996


            Additionally, all continuous service rendered to the Company
            (including service during your current assignment) will be counted
            in calculating the amount of the benefits payable to you from the
            Company's Swiss Pension Plan.



Mr. Jean-Louis Greze

            The Company will, of course, be responsible for, and make, any
            payments to the Swiss Pension Plan that are necessary as a result of
            your continued participation in that Plan in accordance with this
            Section III.

            In the event your employment is involuntarily terminated (not for
            cause) by the Company prior to August 1, 1996, you will commence to
            receive, as of the date of your termination, a lifetime annuity from
            the Company's Swiss Pension Plan based on (i) the amount of
            continuous service that you would have had with the Company if you
            had remained an employee and continued to participate in the
            Company's Swiss Pension Plan until August 1, 1996 and (ii) your
            final average salary as of the date of your termination of
            employment, based on the notional salary schedule specified above.

            Any benefits payable to you from the French Repartition and Social
            Security Systems will be offset against the amount of benefits due
            to you from the Company's Swiss Pension Plan in accordance with this
            Section III.

            The agreement regarding your pension coverage described in this
            Section III is in lieu of, and replaces, all coverages previously
            provided to you under the Company's Third Country National Plan (TCN
            Plan), and you will, therefore, not receive any benefits under the
            TCN Plan.


IV.   MISCELLANEOUS.

      This letter is not intended to be a guarantee of employment, and you and
the Company each have the right to terminate your employment at any time and for
any reason.
