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.

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. Mr. Jean-Louis Greze Page 3 March 1, 1995 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.
