1 Exhibit 10.21 [LETTERHEAD OF HERCULES INCORPORATED] November 1, 2000 Mr. Harry J. Tucci 220 Slonaker Road Spring City, Pennsylvania 19475 Dear Harry: Terms and Conditions of Your Termination From Hercules Incorporated In recognition of your service to Hercules Incorporated ("Company") and your acceptance of your new role as Chairman, CEO and President of CP Kelco, the Board of Directors has authorized me to offer you special benefits and payments. These will be effective when you officially retire from the Company. 1. Hercules Executive Survivor Benefit Plan (H.E.S.B.P.). This benefit provides payments to your beneficiary or estate in case of your death. The payment will be made from Company assets in an amount equal to two (2) times the sum of your final twelve months salary plus the average of your last two calendar year MICP awards. 2. Executive Incentive Plan Stock Forfeiture Reimbursement. Because your retirement causes you to forfeit Above-Target MICP Restricted Stock, Executive Stock Purchase Program and Nonqualified Pension Exchange shares, the Company will reimburse you for the lost shares, valued using the closing price of Hercules stock on your last day of employment. 3. Periodic Payments Having A Total Present Value of $600,000. Concurrent with your retirement, you may elect to receive 120 consecutive monthly payments of $7,000 each, or you may elect an addition to your pension of $4,700/month for life. If you elect to receive the pension annuity, you may elect the usual forms of pension receipt, including a 51% lump sum. These options are in lieu of the payments outlined in the June 29, 1999 R. Keith Elliott letter. 4. Four (4) Additional Years of Pension Service Credit. The Company will provide a total annual pension of $132,500 (before nonqualified pension exchange reduction). This represents the addition of four (4) full years of service, bringing your total added service for beyond actual employment to eight (8) years. This pension will be effective with your retirement and paid in monthly installments. You will have the usual payment elections provided to Hercules retirees. 2 Mr. Harry J. Tucci November 1, 2000 Page 2 5. Pension Supplement for CP Kelco Service. If you remain with CP Kelco until Hercules' normal retirement age 65, Hercules will pay 50% of the cost of increasing your pension from $132,500 to $264,000. Lehman will pay the remaining 50%. This is a fixed dollar amount and not influenced by any other portion of this agreement. In the event you retire from CP Kelco prior to age 65 (May 2005), you will receive a prorated portion of the additional pension calculated by dividing (a) the number of months between Hercules retirement and your CP Kelco date of retirement, by (b) the number of months between your Hercules retirement and 6/l/05. 6. Full Share BetzDearborn Integration Bonus Plan. Provided that Plan awards are earned and payouts are approved by the Hercules Compensation Committee and the Hercules Board of Directors, you will be paid at the same time, in the same form, and upon the same terms as other Plan participants. Your bonus will be a full share with no pro-ration. 7. Custodial Care for your Spouse. Hercules will reimburse the care provided for your wife through September 29. Additional reimbursement will be charged to CP Kelco and subject to authorization from CP Kelco. This letter represents the full and complete offer by Hercules consistent with your signed Employment Agreement dated September 30, 2000 and CP Kelco ApS, and in order to complete your retirement from Hercules in an orderly manner, please indicate your acceptance of these special terms and conditions by signing a copy of this letter and returning it to me no later than November 22. In addition, please sign a copy of the attached waiver and release form claims and return it to me by the same date. Sincerely, HERCULES INCORPORATED /s/ Thomas L.
