Bolduc 3000 South Ocean Boulevard Boca Raton, FL 33432 Dear JP, This will confirm the arrangements relating to your retirement as President and Chief Executive Officer of W. R. Grace & Co. ("Company"), which have previously been approved by you and by the Board of Directors of the Company on the recommendation of its Compensation, Employee Benefits and Stock Incentive Committee, as well as the three-person special Committee of the Board appointed to negotiate these arrangements with you. These arrangements follow: 1. You have resigned your positions as President and Chief Executive Officer of the Company effective March 3, 1995. You will remain an employee and be paid through and be retired on March 31, 1995. 2. You agree that your Employment Agreement with the Company, as amended, will terminate and be of no further force and effect effective March 3, 1995. In consideration of the termination of your Employment Agreement, the Company agrees to pay you $5,062,208, less applicable tax withholding, promptly following the execution of this letter (see Exhibit I). This payment is in lieu of monthly severance payments for the balance of the term of your Employment Agreement and renders inoperable the provision dealing with reducing monthly severance payments by outside "Earned Income". 3. In addition, effective immediately following your retirement on March 31, 1995: - You are entitled to receive a gross pension benefit, before adjustments and tax withholding, of $1,081,000 per year. (This pension benefit is calculated in accordance with the terms of your -2- Employment Agreement. It will not be reduced because of age (62 vs. 55 years). - It will include full pension benefits to be paid to you as though you were 62 years of age and, based on your plan to elect a 100% joint and survivor benefit, it will be adjusted for such election. Therefore, after adjusting for joint and survivor, your annual pension benefit will be $848,584.92, less applicable tax withholding. Full post-retirement medical -- family medical plan -- will be provided to you and your spouse for life, as it may be continued or amended from time to time, with your cost share monthly payment equal to the amount paid by other retirees, currently at $276.36 and such amount as it may be adjusted from time to time for similarly situated retirees. 4. You will continue to receive your current split dollar life insurance coverage (Confederation Life Policy Nos. 5-181-624 and 5-181-625 or their successors) with a total face value of $4.5 million. Annual premiums will continue to be shared by you and the Company as scheduled according to your age. These terms, as well as all other terms and conditions of the policies, will continue in full force and effect under the same terms and conditions as similar policies are maintained for other executives of the Company. At age 68, when these policies are transferred to you, they are expected to have an estimated total face value of $5,420,000 and estimated aggregate cash surrender values of $2,068,000, although it is understood these figures will depend on the performance of the policies (and the insurance carrier's dividends) and are not guaranteed by the Company. 5. In total, you currently own 268,348 common shares. Notwithstanding any restrictions in effect as to any such shares of Company Common Stock awarded to you under a restricted stock award program or any other form of restriction, these 268,348 shares will be purchased promptly, following the execution of this letter, by the Company at $45 per share for total proceeds due you of $12,075,660, less applicable tax withholdings with respect to 5,725 shares which were previously not vested (see Exhibit II). 6. Your participation in the Company's Long-Term Incentive Program for the 1993-94-95 and the 1994-95-96 periods will be paid to you, less applicable tax withholding, on the execution of this letter (see Exhibit III) as follows: 1993-1995 Performance Period $ 812,500 1994-1996 Performance Period 437,500 ---------- TOTAL $1,250,000 -3- 7. You previously have been granted 655,000 stock options under a stock incentive plan of the Company. Of these 655,000, 290,000 are not fully exercisable. In consideration of your retirement from the Company, options on those 290,000 shares will be immediately fully vested. Therefore, options on all 655,000 shares are immediately exercisable and may be exercised at any time during the 36-month grace period following your retirement through March 31, 1998. 8. Your total Deferred Compensation balance of $1,529,604, as of February 28, 1995, consists of the following balances: - $290,295 plus interest to date of payment, less applicable taxes, payable in lump sum on April 30, 1995, - $1,180,502 payable in quarterly installments over 10 years beginning 6/30/95, and - $58,807 payable quarterly over ten years beginning at the end of the quarter following the date on which you notify the Company of your permanent retirement from any employer. You agreed that in consideration of your retirement from the Company, these balances would be consolidated into one single balance which will be payable in quarterly installments over ten years beginning June 30, 1995, in accordance with all terms and conditions of the Company's Deferred Compensation Program. 9. Your Savings and Investment balance of $582,343 does not include the February 1995 second pay period savings/contributions or Fixed Income Fund earnings for February. These amounts will be posted and adjusted accordingly.
