                                  CONFIDENTIAL

                              SEPARATION AGREEMENT
                          AND GENERAL RELEASE OF CLAIMS

                  This Separation Agreement and General Release of Claims
("Agreement") is entered into between Hercules Incorporated ("Employer"), and
George MacKenzie ("Employee").

                  In consideration of the mutual promises and covenants
contained herein and other good and valuable consideration, the receipt of which
hereby is acknowledged, the parties agree as follows:

1.       SEPARATION DATE. Effective upon the close of business on June 30, 2001,
         Employee shall cease to be employed by Employer (the "Separation Date")
         and shall become a Pensioner (as that term is defined in the Hercules
         Retirement Pension Plan) effective July 1, 2001. Between now and the
         Separation Date and for 30 days following said Separation Date on an as
         needed" basis (at no additional charge to Employer), Employee shall
         assist in transitioning his duties and responsibilities, and perform
         such other duties and responsibilities as he may be assigned that are
         not inconsistent therewith.

2.       SEVERANCE PAYMENT. Within twenty (20) days of receipt of this
         Agreement, executed by Employee, and provided Employee has not revoked
         this Agreement in accordance with paragraph 16 below, Employer shall
         pay to Employee severance in the amount of One Million Six Hundred
         Fifty Thousand dollars ($1,650,000.00), less all applicable
         withholdings and deductions. Employee expressly waives all rights to
         benefits under the Merger Severance Plan, Change in Control Agreement,
         Severance Plan, and under any and all other plans or agreements
         purporting to provide for severance payments.

3.       SPECIAL PENSION BENEFITS. In addition to Employee's regular benefit
         entitlement under the Pension Plan of Hercules Incorporated, Employee
         will be granted a special pension benefit payable under the Hercules
         Employee Pension Restoration Plan of $13,172.59 per month effective
         July 1, 2001, such amount payable until age 55 after which the amount
         will be $11,312.43, subject to optional forms of payment elections
         pursuant to the Pension Plan of Hercules Incorporated. This benefit is
         derived by adding 5-1/2 years to Employee's current age and three years
         to Employee's current credited service, then using these additions to
         calculate Employee's pension entitlement pursuant to the Pension Plan
         of Hercules Incorporated and subtracting the benefit calculated not
         using these additions. The total lifetime benefit from all Plans will
         be $14,376.95 per month payable as a single life annuity.

         Additionally, Employee shall be entitled to a special pension benefit
         of $16,677 per year payable in monthly installments for a period
         commencing July 1, 2001 and ending June 30, 2011. This benefit is not
         subject to the 5l% lump sum payment option but is subject to the normal
         joint and survivor option election provisions of the Pension Plan of
         Hercules Incorporated.



                                                                               1
   2
                                  CONFIDENTIAL


         All of the additional benefits payable pursuant to the terms of this
         Agreement are payable under the Hercules Pension Restoration Plan which
         is a nonqualified pension plan payable from the assets of Hercules
         Incorporated.

4.       ACCRUED VACATION PAY. Employer shall pay to Employee his earned but not
         taken plus accrued vacation calculated as of June 30, 2001 in the
         amount of 54 days, less 5 days taken in 2001, such amount equal to
         Ninety-Four Thousand Five Hundred Forty dollars and Fifty-Eight cents
         ($94,540.58), less applicable deductions and withholdings. Employee
         accepts this payment in full satisfaction for vacation time and hereby
         acknowledges and agrees that he is not entitled to any additional
         payment for accrued vacation time.

5.       Employee meets the age and severance requirement to be a Pensioner as
         that term is defined in the Pension Plan of Hercules Incorporated. As
         such, Employee will be eligible to continue participation in the Health
         Care Plans applicable to Pensioners and the Hercules Executive Survivor
         Benefit Plan.

6.       DENTAL BENEFIT CONTINUATION. Upon an appropriate triggering event,
         Employer shall issue to Employee notice of his right to elect continued
         dental coverage in accordance with the Consolidated Omnibus Budget
         Reconciliation Act ("COBRA"). If Employee elects continuation coverage,
         Employee shall be responsible for paying 100% of the premiums and
         administrative fees.

7.       IMPACT OF SEVERANCE ON OTHER BENEFITS. Except as expressly provided in
         this Agreement, or pursuant to the terms of benefit plans applicable to
         Pensioners, both Employee's and his dependents' participation in,
         coverage by and entitlement to all compensation, fringe benefit and
         employee benefit programs of Employer shall cease upon the Separation
         Date. Employer and Employee specifically agree that Employee is, and
         will remain, eligible for Retiree Medical Coverage as long as it is
         offered to other pensioners from the same employment status as Employee
         and remain eligible to participate in the Hercules Executive Survivor
         Benefit Plan.

         Pursuant to Hercules benefit plan policy applicable to pensioners,
         Employee is eligible to enroll Employee and his eligible dependents in
         any of the available Health Care Plans applicable to Pensioners. Under
         this Policy and as long as it is available to Pensioners, Employee may
         suspend participation for a period of time and then re-enroll at a
         later date. Hercules reserves the right to amend, suspend or terminate
         this Plan at any time.

         Employee, as a participant in the Hercules Executive Survivor Benefit
         Plan, will maintain coverage applicable to pensioners in the amount of
         two times final annual salary ($1MM). This is a non-insured benefit and
         not subject to tax gross-up.



                                                                               2

                                  CONFIDENTIAL


8.       COOPERATION FOLLOWING THE SEPARATION DATE. Employee agrees that he will
         cooperate with any reasonable request of Employer to continue to aid in
         the transition of his function or to answer questions regarding his
         functional area following the Separation Date. Employee, prior to June
         30, 2001, agrees to list all open projects, accountabilities and
         unfinished assignments with a description of status.

9.       AGREEMENT TO RESIGN BOARD APPOINTMENT. Employee agrees to resign as of
         the next meeting from all Board assignments applicable to the Company,
         affiliated Companies or subsidiaries of Hercules.

10.      NO ADMISSION. The benefits provided to Employee in this Agreement are
         not intended to be, and shall not be construed as, any admission of
         liability by Employer or of any improper conduct on Employer's part,
         all of which Employer specifically denies.

11.      COMPANY INFORMATION.

                  (a) Employee represents that he has returned or will

         information received from third parties under confidential conditions,
         and (ii) other information; including technical, business or financial
         information or trade secrets, the use or disclosure of which might
         reasonably be construed to be contrary to the interests of Employer or
         its affiliates.

                  (b) The parties agree that in the course of Employee's
         employment, Employee has acquired Company Information as defined in

         of the Board of Directors for the Employer.



                                                                               3
