               -----------------------
               for membership under Section 2.01 above is rehired after a
               Severance from Service Date as defined in Section 3.02(d), the

                   the Employment Commencement Date of the Employee shall be the
                   first day on which the Employee performs an Hour of Service
                   after incurring such a Break in Service.

                   paid, or entitled to payment, for the performance of duties

               to the service of the Company within the period during which re-
               employment rights are extended by law, such absence shall not
               count as a period of severance. Any period of such absence which
               is not otherwise included in his Period of Service shall be so
               included.

Section 3.04   Family Medical Leave.  If an Employee is absent from the service

              (a) Each Member may elect to reduce his Compensation in any amount
                  from two percent (2%) to twelve percent (12%) [in one percent
                  (1%) increments] of his Compensation for each payroll period
                  subject to the provisions set forth in Sections 4.04(g), 4.08,
                  and Article XIX, and his Employer shall remit an amount equal
                  to the amount of the reduction in his Compensation to the Plan
                  on his behalf as soon as practicable after the end of the
                  payroll period.

              (b) For a Member who has (1) completed a one (1) year Period of
                  Service, or (2) was an Eligible Employee on the Effective Date
                  of this Plan, the first six percent (6%) of contributions
                  under this paragraph shall be considered Basic Matched
                  Contributions, and a Company Contribution shall be made with
                  respect to such contributions in accordance with Section 4.02.
                  Any contributions other than those described in the preceding
                  sentence shall be considered Basic Unmatched Contributions.

              (c) Notwithstanding the foregoing, the Employer shall not remit to
                  the Plan any Basic Matched Contributions or Basic Unmatched
                  Contributions on behalf of any Member who receives a hardship
                  withdrawal of his Basic Contribution Account or his Company
                  Matching Contribution Account in accordance with Section
                  11.02, during the twelve-month period immediately following

              (a)  The Company shall contribute out of its accumulated earnings

              (b)  In the event that the Commissioner of Internal Revenue, on
                   timely application made after the adoption of the Plan, as
                   restated, determines that the Plan and the implementing trust
                   do not qualify for tax-exempt status, or refuses, in writing,
                   to issue a favorable determination with respect to the Plan
                   and such trust, the Employer contributions made on or after
                   the date on which such determination or refusal is applicable
                   shall be returned to the Employer without interest. In the
                   event that an Employer contribution to the Plan is made by a
                   mistake of fact or all or part of the Employer's deductions
                   under Code Section 404 for contributions to the Plan are
                   disallowed by the Internal Revenue Service, the portion of
                   the contributions attributable to such mistake of fact or to
                   which such disallowance applies shall be returned to the
                   Employer without interest.

                   Any such return shall be made within one year after the
                   making of such contribution by mistake of fact or the denial
                   of qualification or disallowance of deductions, as the case
                   may be.

              (c)  Company Matching Contributions shall be suspended for six
                   months if a Member withdraws any or all of his Company
                   Matching Contributions deposited in his Account during the
                   two years preceding the withdrawal under Section 11.04.

               --------------------------

              (a)  A Member may elect to make after-tax Supplemental

                   percent (1%) to ten percent (10%) of his Compensation in one
                   percent, (1%) increments which shall be paid to the Trustee
                   as soon as practicable. A Member's election of Supplemental
                   Contributions may be made in addition to any Basic Matched
                   or Basic Unmatched Contributions elected by the Member, or
                   may be made in lieu of such other contributions, subject to
                   the provisions set forth in Section 4.05(h) and Article
                   XVIII.

              (b)  The Plan Administrator may implement rules limiting the
                   Supplemental Contributions which may be made on behalf of
                   some or all Highly Compensated Employees so that the limits
                   set forth in Article XIX are satisfied.

               (c)  Notwithstanding the foregoing, a Member may not elect to
                    make after-tax Supplemental Contributions during the twelve-
                    month period immediately following the distribution of any
                    hardship withdrawal of his Basic Contribution Account or his
                    Company Matching Contribution Account made in accordance
                    with Section 11.02.

Section 4.04   Deferral Percentages.
               --------------------

               (a)  The actual deferral percentage for the Highly Compensated
                    Employees shall satisfy at least one of the following tests:

                    (i)  The actual deferral percentage for the eligible Highly
                         Compensated Employees for the Plan Year does not exceed
                         the actual deferred percentage for the eligible Non-
                         Highly Compensated Employees for the preceding Plan
                         Year, multiplied by 1.25; or

                    (ii) The actual deferral percentage for the eligible Highly
                         Compensated Employees for the Plan Year does not exceed
                         the actual deferral percentage for the eligible Non-
                         Highly Compensated Employees for the preceding Plan
                         Year, multiplied by 2.0; provided, however, that the
                         actual deferral percentage for the eligible Highly
                         Compensated Employees may not exceed the actual
                         deferral percentage for the eligible Non-Highly
                         Compensated Employees by more than two percentage
                         points.

              (b)(1) The actual deferral percentage with respect to Basic
                     Matched Contributions for a specified group of Employees
                     for a Plan Year shall be the average of the ratios
                     (calculated separately for each Employee in such group) of:

                    (i)  The amount of Basic Matched Contributions actually paid
                         to the Plan on behalf of each such Employee for such
                         Plan Year, to

                   (ii)  The Employee's compensation (within the meaning of Code
                         Section 414(a)) for such Plan Year.

              (b)(2) The actual deferral percentage with respect to Basic
                     Unmatched Contributions for a specified group of
                     Employees for a Plan Year shall be the average of the
                     ratios (calculated separately for each Employee in such
                     group) of:

                                       13
<PAGE>

                 (i) The amount of Basic Unmatched Contributions actually paid
                     to the Plan on behalf of each such Employee for such Plan
                     Year, to

                (ii) The Employee's compensation (within the meaning of Code
                     Section 414(a)) for such Plan Year.

           (b)(3)  In each case referred to in Sections (b)(1) and (b)(2), the
                   actual deferral percentage test described in Section 4.05(a)
                   shall be computed separately for each controlled group
                   [determined in accordance with Code Sections 414(b), (c),
                   (m), (n), and (o)] whose Employees participate in the Plan.

           (c)     In making the deferral percentage calculations set forth
                   above, the Plan Administrator, as permitted by law, may, but
                   is not required to, take into account other contributions
                   made by the Company on behalf of Eligible Employees; provided
                   that such other contributions must be one hundred percent
                   (100%) vested and subject to the withdrawal restrictions
                   applicable to qualified non-elective contributions [as
                   defined in Code Section 401(m)].

           (d)     If the actual deferral percentage of eligible Highly
                   Compensated Employees exceeds the amounts allowed under
                   Paragraphs (a) and (b) above, the excess deferrals (as
                   determined below) shall be distributed to the Members as soon
                   as practicable (but in no event later than the last day of
                   the next succeeding Plan Year). Any such distribution shall
                   include income and loss allocated to the excess in accordance
                   with Reg. Section 1.401(k)-l(f)(4).

           (e)     The amount of excess deferrals to be so distributed to a
                   Highly Compensated Employee shall be determined separately
                   with respect to Basic Matched and Basic Unmatched
                   Contributions and, in each case, shall equal

                   (i)  The total deferrals specified in clause (i) of Section
                        4.05(b)(1) or (b)(2), as the case may be, for such
                        employee, less

                   (ii) The reduced deferral percentage (determined below) for
                        such employee with respect to Basic Matched or Basic
                        Unmatched Contributions, as the case may be, multiplied
                        by his Compensation for the Plan Year.

                                       14
<PAGE>

              (f)  The reduced deferral percentage for each Highly Compensated
                   Employee shall be determined by reducing the Basic Matched or
                   Basic Unmatched Contributions, as applicable, of the Highly
                   Compensated Employee with the highest dollar amount of
                   deferral to whichever of the following is higher:

                     (i)  The amount which enables the highly compensated group
                          to satisfy one of the tests of paragraph (a)(1); or

                     (ii) The amount that is equal to that of the Highly
                          Compensated Employee with the next highest Basic
                          Matched or Basic Unmatched Contributions, as
                          applicable.

                   The above process shall be repeated until the highly
                   compensated group satisfies one of the tests set forth in
                   paragraph (a).

              (g)  The Plan Administrator may implement rules limiting the Basic
                   Matched and Unmatched Contributions which may be made on
                   behalf of some or all Highly Compensated Employees so that
                   the tests set forth in Section 4.04 are satisfied.

Section 4.05  Contribution Percentages.
              ------------------------

              (a)  The actual contribution percentage for the Highly Compensated
                   Employees, for each Plan Year, shall not exceed the greater
                   of (i) the actual contribution percentage for eligible Non-
                   Highly Compensated Employees for the preceding Plan Year
                   multiplied by 1.25, or (ii) the lesser of (A) two hundred
                   percent (200%) of the actual contribution percentage of the
                   eligible Non-Highly Compensated Employees, or (B) the actual
                   contribution percentage of the eligible Non-Highly
                   Compensated Employees, plus two (2) percentage points.

              (b)  The actual contribution percentage with respect to
                   contributions to the Plan for a specified group of Employees
                   for a Plan Year shall be the average of the ratios
                   (calculated separately for each Employee in such group) of:

                     (i)  The sum of each of the following which are actually
                          paid to the Plan on behalf of such Employee for such
                          Plan Year,

                         (C) Any Qualified Non-Elective Contributions and
                             Qualified Matching Contributions, to

                         Code Section 414(a)) for such Plan Year.

             (c)   In making the contribution percentage calculations set forth
                   above, the Plan Administrator, as permitted by law, may, but
                   is not required to, take into account other contributions
                   made by the Company on behalf of Eligible Employees,
                   including Qualified Non-Elective Contributions and Qualified
                   Matching Contributions.

             (d)   If the actual contribution percentage of Highly Compensated
                   Employees exceeds the amounts allowed under Paragraphs (a)
                   and (b) above, the excess contributions (as determined below)
                   shall be distributed to the Members as soon as practicable
                   (but in no event later than the last day of the next
                   succeeding Plan Year). Any such distribution shall include
                   income and loss allocated to the excess in accordance with
                   Reg. Section 1.401(m)-l(e)(3).

             (e)   The amount of excess contributions to be so distributed to a
                   Highly Compensated Employee shall equal

                    (i)  The total contributions specified in clause (i) of
                         Section 4.05(b)(1) or (2), as the case may be, for such
                         Employee, less

                    (ii) The reduced contribution percentage (determined below)
                         for such employee with respect to contributions to the
                         contributions to the Investment Funds, as the case may
                         be, multiplied by his Compensation for the Plan Year.

             (f)   The reduced contribution percentage for each Highly
                   Compensated Employee shall be determined by reducing the
                   Supplemental Contributions and Company Matching Contributions
                   of the Highly Compensated Employee with the highest dollar
                   amount of Company Matching Contributions and Supplemental
                   Contributions to whichever of the following is higher:

                                       16
<PAGE>

                          (i) The amount which enables the highly compensated
                              group to satisfy one of the tests of paragraph
                              (a)(l); or

                         (ii) The amount that is equal to that of the Highly
                              Compensated Employee with the next highest dollar
                              amount of Company Matching Contributions and
                              Supplemental Contributions.

                     The above process shall be repeated until the highly
                     compensated group satisfies one of the tests set forth in
                     paragraph (a).

                (g)  The multiple use of the alternative non-discrimination
                     tests set forth in Section 4.04(a)(ii) and Section
                     4.05(a)(ii) shall be limited as prescribed by law. If
                     restrictions on such multiple use apply, the Plan
                     Administrator shall designate either the actual deferral
                     percentages or the actual contribution percentages of
                     Highly Compensated Employees to be reduced, and shall
                     reduce such percentages in the manner described above,
                     until the multiple use limitations are no longer exceeded.

                (h)  The Plan Administrator may implement rules limiting the
                     Supplemental Contributions which may be made by some or all
                     Highly Compensated Employees, so that the test set forth in
                     Section 4.05(a) is satisfied.

                Administrator, provided the notice of the change is given
                according to such procedures as the Plan Administrator shall
                prescribe. In addition, where Basic Matched, Basic Unmatched, or
                Supplemental Contributions by payroll deduction are or may be
                prohibited by law, in the opinion of counsel to the Company, a
                Member, upon approval by the Plan Administrator, may make
                contributions directly to the Trustee for each payroll period by
                a method satisfactory to the Plan Administrator as long as such
                deposits are timely made on the same schedule as payroll
                deductions. The Trustee shall not accept direct contributions
                not timely made by a Member.

                   the 12-month period of employment preceding the period of

          (a)  Each member shall be entitled to direct the Trustee as to the
               manner in which voting rights with respect to shares or units
               represented by the Member's Account invested in the Fund are to
               be exercised. The Trustee shall vote the number of shares in
               accordance with such instructions. With respect to units of the

               ----------------
Company and maintained by the Trustee, from time to time may include the
following:

            (a)   U.S. Government Money Market Fund.  The objective of the Fund
                  ---------------------------------
                  is to seek the maximum current income consistent with
                  preservation of principal and liquidity.  The Fund invests in
                  short-term securities issued by the United States Government,
                  its agencies and instrumentalities, and in repurchase
                  agreements collateralized by such securities.  A portion of
                  the U.S. Government securities held by the Federal Portfolio
                  may not be backed by the full faith and credit of the U.S.
                  Government.

            (b)   Fixed Income Fund.  The objective of the Fund is to provide a
                  -----------------
                  stable principal amount, but a higher yield than can be earned
                  in a money market fund.  Assets are primarily invested in
                  contracts with

                                       21
<PAGE>

                  insurance companies which provide for repayment by the issuing
                  company of principal with interest at a fixed rate, or fixed
                  minimum rate, for a specified period and in short-term
                  corporate and government bonds. The yield on the Fund is a
                  blended rate reflecting the interest rates on all investments
                  in the Fund.

            (c)   Balanced Fund.  The objective of this Fund is to follow a
                  -------------
                  diversified and balanced program of investing in bonds and
                  common stock.  The Fund invests sixty-seventy percent (60%-
                  70%) of its net assets in stocks of large well-known companies
                  and thirty-forty percent (30%-40%) of its net assets in long-
                  term high-quality bonds.  The Fund is designed to provide
                  conservation of principal, a reasonable income return, and
                  potential growth of capital.

            (d)   Equity Index Fund.  A growth and income fund, the Fund invests
                  -----------------
                  in all of the stock included in the Standard & Poor's 500
                  Index in approximately the same proportions as they are
                  represented in the S&P 500 Index.  The Fund is designed to
                  provide investment results that correspond to the performance
                  of the Standard & Poor's 500 Composite Stock Price Index.

            (e)   Growth and Income Fund.  This Fund invests in common stocks
                  ----------------------
                  that have a history of paying dividends.  The Fund selects
                  common stocks that, in the opinion of the investment manager,
                  are undervalued in the marketplace.  The Fund seeks long-term
                  capital growth and a reasonable level of dividend income.

            (f)   Aggressive Growth Fund.  The Fund primarily invests in common
                  ----------------------
                  stocks of smaller companies with favorable prospects for
                  growth in market value.  The Fund seeks long-term growth of
                  capital.

            (g)   International Growth Fund.  This Fund invests in a diversified
                  -------------------------
                  portfolio of international stocks, or stocks of companies
                  based outside of the United States.  The Portfolio seeks to
                  provide long-term growth of capital.  The Portfolio provides
                  little, if any, dividend income.

            (h)   DuPont Common Stock Fund.  This Fund is a unitized fund
                  ------------------------
                  holding shares of common stock of E.I du Pont de Nemours and

              ---------------------------

                  Contributions, remitted to the Plan and credited to a Member's
                  Accounts will be invested at the election of the Member in
                  multiples of one percent (1%) in the Investment Funds
                  authorized by the Company and maintained by the Trustee in
                  accordance with Section 6.01. Contributions for which a Member
                  does not make a valid election shall be invested in the U.S.
                  Government Money Market Fund, or such other Investment Fund as
                  the Plan Administrator designates from time to time. Company
                  Matching Contributions shall be invested initially in the
                  DuPont Common Stock Fund, but may be transferred to other
                  Investment Funds at any time in accordance with paragraph (b).

                  Investment directions of each new Member shall be delivered in
                  writing to the Plan Administrator or its delegate. A Member
                  may change his direction governing investment of future
                  contributions to be credited to his respective Accounts at any
                  time upon providing the appropriate notice to the Plan
                  Administrator or its delegate. An investment direction once
                  given shall be deemed to be a continuing direction until
                  explicitly changed by the Member by a subsequent direction to
                  the Plan Administrator or its delegate in accordance with
                  appropriate procedures set forth by the Plan Administrator or
                  its delegates.

            (b)   Transfer of Investments.  A Member may elect, at any time, to
                  -----------------------
                  have all or any multiple of one percent (1%) of the value of
                  his Account as of any future Valuation Date or any dollar
                  amount of his Account transferred to any separate Investment
                  Fund maintained by the Trustee in accordance with Section
                  6.01.

            (c)   Notwithstanding anything in this Section to the contrary, any
                  contributions invested in an investment contract shall be
                  subject to any and all terms of such contract, regarding the
                  transfer of assets from such contract.

Section 6.03  Member Responsibility For Selection of Funds.  Each Member is
              --------------------------------------------
              solely responsible for the selection of his Investment Funds.
              Neither the Trustee, the Plan Administrator, the Company nor any
              of the officers supervisors of the Company are empowered to advise
              a Member as to the manner in which his Accounts shall be invested.
              The fact that a security is available to members for investment
              under the Plan shall not be construed as a recommendation for the
              purchase of that security, nor shall the designation of any
              Investment Fund impose any liability on the Company, its
              directors, officers or employees, the Trustee, or the Plan
              Administrator.

              When an investment election regarding the Fund is required to be
              made by Members, such Member shall be informed as to the manner in
              which their funds will be invested if they fail to make an
              affirmative election in a timely manner. In such event, those
              Members who fail to communicate an election to the Plan
              Administrator or its delegates shall be deemed to have elected the
              specified investment by default and the Company, its directors,
              officers or employees, the Trustee, and any other plan fiduciary
              shall be deemed to be relieved of fiduciary responsibility for the
              investment of such funds.

                  distributable in accordance with Article VIII (Vesting of
                  Contributions) and shall be determined as of the Valuation
                  Date on which the Trustee receives properly authorized
                  instructions to make the payment from the Plan Administrator,
                  and such amount, as adjusted in accordance with Section 9.06,

                      installments, (C) declining balance installments, or (D)

            (b)   Notwithstanding any provision of the Plan to the contrary that
                  would otherwise limit a Distributee's election under Section
                  9.02, a Distributee may elect, at the time and in the manner
                  prescribed by the Plan Administrator or its delegatee to have

                  any distribution of all or any portion of the balance to the
                  credit of the Distributee's Accounts except that an Eligible

                  (not less frequently than annually) made for the life (or life
                  expectancy) of the Distributee or the joint lives (or joint
                  life expectancies) of the Distributee and the Distributee's
                  designated beneficiary, or for a specified period of ten (10)
                  years or more; any distribution to the extent such
                  distribution is required under Code Section 401(a)(9) and the
                  portion of any distribution that is not includible in gross
                  income (determined without regard to the exclusion for net

                  However, in the case of an Eligible Rollover Distribution of
                  the surviving spouse, an Eligible Retirement Plan is an
                  individual retirement account or individual retirement

                  A "Distributee" includes an Employee or former Employee. In
                  addition, the Employee's or former Employee's surviving spouse
                  and the Employees' or former Employee's spouse or former
                  spouse who is the alternate payee under a qualified domestic
                  relations order, as defined in Code Section 414(p) are
                  Distributee's with regard to the interest of the spouse or
                  former spouse.

                  A "Direct Rollover" shall mean a payment by the Plan to the
                  Eligible Retirement Plan specified by the Distributee.

Section 9.03  Completion of Appropriate Forms.  The Plan Administrator has
              -------------------------------
              prescribed forms providing written notice to the Company in order
              for a distribution to be made under the Plan. In the event a
              Member or a Beneficiary does not complete, execute and return such
              forms to the Company, the distribution of such Member's Accounts
              shall (except to the extent provided in Section 16.09), be mailed,
              as provided in Section 9.02(d) in cash, to the Address of Record
              as provided in Section 16.08 to a Member as soon as practicable
              following the sixty-fifth (65th) birthday of such Member, or to a
              Beneficiary. The Valuation Date for purposes of this Section 9.05
              shall be as described in Article VII.

Section 9.04  Accounts of Former Employees.  The amount credited to the accounts
              ----------------------------
              of a Member, if any, after Termination of Employment of such
              Member shall be adjusted in accordance with Article VII as of each
              Valuation Date next following such Termination of Employment until
              such amount shall have been distributed in full in accordance with
              this Article. Distribution of the balance of the amount credited
              to the Accounts of a Member, determined as of the Valuation Date
              immediately preceding such distribution, shall constitute payment
              in full of the benefits of such Member hereunder. Any balance of
              such accounts remaining unpaid at the death of a Member or
              Beneficiary shall be distributed in accordance with Article VIII.

              Any amounts being held for deferred distribution will continue to
              be held by the Trustee and invested in accordance with the
              instructions of the Members. Such instructions will be given in
              accordance with the provisions of this Plan. Persons receiving a
              deferred distribution are former Members and shall not be credited
              with Basic, Supplemental or Matching Company Contributions after
              Termination of Employment, except with respect to compensation
              paid subsequent to the Termination of Employment but attributable
              to services performed as an Employee in Covered Service.

              is $3,500 or less (after January 1, 1998, $5,000), it shall be
              distributed in a lump sum payment; and (b) if the vested portion
              of the Accounts of a Member exceeds $3,500 (after January 1, 1998,

              shall not provide for deferment of payments extending beyond the
              following periods:

              (a) If the Beneficiary or contingent annuitant of a Member under
                  any method of distribution is other than his Eligible Spouse,
                  the actuarial present value of payments expected to be made to
                  the Member shall not be less than fifty-one percent (51%) of
                  the total actuarial present value of the benefits expected to
                  be paid to the Member and his Beneficiary or contingent
                  annuitant.

              (b) Unless the Member elects otherwise in writing, the latest date

                  Termination of Employment; and (3) ten (10) years have elapsed
                  from the time the Member commenced participation in the Plan.

                  If payment in full is not feasible within the time limits
                  prescribed by this subsection (b) the Plan Administrator may
                  make interim payments from accounts of the Member.

              (c) Notwithstanding anything to the contrary in this Plan and
                  regardless of any election by the Member, payment of benefits
                  shall commence no later than the April 1 of the calendar year
                  following the earlier of the calendar year in which the Member
                  attains age seventy and one-half (70-1/2) years, or the
                  calendar year in which the Member actually retires, provided
                  that a Member who attained age seventy and one-half (70-1/2)
                  prior to January 1, 1988, who is

                  not a five-percent (5%) owner, may defer commencement of
                  benefits until the April 1 of the calendar year following the
                  calendar year in which such Member actually retires. The
                  minimum distribution to be made each year shall be the amount
                  equal to the quotient obtained by dividing the Member's
                  Account balance at the beginning of the year by the life
                  expectancy of the Member (or the joint life and last survivor
                  expectancy of the Member and the Beneficiary). If payments are
                  made over the life expectancy of the Member, or the joint life
                  expectancy of the Member and his spouse, life expectancy will
                  be determined either: (1) only once, at the time the Member
                  (or his spouse) receives the first distribution of his account
                  balance; or (2) periodically, but no more frequently than
                  annually. If payments are made over the joint life expectancy
                  of the Member and a non-spouse Beneficiary, the change in the
                  life expectancy of the Member may be determined periodically,
                  but not more frequently than annually; but the life expectancy
                  of the non-spouse Beneficiary shall be determined only once at
                  the time the Member (or Beneficiary) receives the first
                  distribution of his account balance.

Section 9.07  Lost Payees.  In the event the amount credited to the Account(s)
              -----------
              of a Member remain unclaimed for more than five (5) years after
              such amount becomes distributable pursuant to Section 9.07, and
              the Plan Administrator is unable to locate such Member (or his
              Beneficiary), the Plan Administrator may direct such amount to be
              applied to reduce Company Matching Contributions provided that in
              the event such Member (or his Beneficiary) subsequently claims
              such amounts, the Employer shall contribute an amount to the Plan
              which will cause the balance of such Member's account(s) to equal
              the amount which would have been credited to such account(s) as of
              such date if such amounts had never been reallocated pursuant to
              this Section.

Section 10.02  Beneficiary Designation.  Subject to Section 10.03, each Member
               -----------------------
               from time to time on a form acceptable to the Plan Administrator
               may designate any person (including a trust) or persons
               (concurrently, contingently or successively) to whom the Member's
               benefits under the Plan are to be paid if the Member dies before
               receiving all of such benefits. A beneficiary designation form
               shall be effective only when the form is filed in writing by the
               Member and shall cancel all beneficiary designation forms
               previously signed and filed by the Member.

               With respect to a Member who has at least one Hour of Service
               after August 22, 1984, the designation of a non-spouse
               Beneficiary shall be valid only if the surviving spouse of the
               Member shall have consented in writing to such designation, the
               consent acknowledges the effect of such designation and the
               consent is witnessed by a Plan representative or a notary public.

               sum payment as soon as practicable after the death of the Member.
               Such payment shall be made to the Member's Eligible Spouse unless
               such Eligible Spouse has consented to another beneficiary
               pursuant to Section 10.02.

               distributed, the remaining portion of such interest shall be
               distributed at least as rapidly as the distribution option
               elected by the Member.

               If a Member dies before a distribution of benefits has commenced,
               the entire interest shall be distributed within five (5) years of
               the Member's death; unless any portion of the interest is payable
               to or for a Beneficiary over a period not to exceed the life or
               life expectancy of the Beneficiary and payments commence within
               one year after the Member's death. However, if the Beneficiary is
               the surviving spouse of the Member, distribution need not
               commence before the date when the Member would have attained age
               seventy and one-half (70-1/2) years; provided that if the
               surviving spouse dies before distribution to such spouse begins,
               this paragraph shall be applied as if the surviving spouse were
               the Member.

               legal representative, be paid to his spouse, a child, a parent or
               other blood relative, a person with whom he resides, or to any
               other person the Plan Administrator considers suitable, and any
               such payment so made shall be a complete discharge of the

               and unqualified refusal to accept such a benefit with the Plan
               Administrator before receiving any such benefit. If such a
               renunciation is filed by the Eligible Spouse of the Member, the
               value of the annuity described in Section 10.03 shall be zero.
               Any benefits so disclaimed shall be distributable to the person
               or persons (and in the proportions) to which such benefit would
               have been distributable if the Beneficiary who so disclaims such
               benefits had predeceased such Member.

               Contribution Account by submitting his request to the Plan
               Administrator at such time and in such manner as shall be
               prescribed by the Plan Administrator subject to the following
               provisions:

               (a)   The withdrawal request must be for an immediate and heavy
                     financial need on account of:

                     (1)   Nonreimbursable medical expenses incurred by the
                           Member, his Spouse, or dependents;

                     (2)   Costs directly related to the purchase (excluding
                           mortgage payments) of a principal residence for the
                           Member;

                     (3)   Payment of tuition, related educational fees, and
                           room and board for the next twelve (12) months of
                           post-secondary education for the Member, his Spouse,
                           or dependents; or

                     (4)   The need to prevent the eviction of the Member from
                           his principal residence or foreclosure on the
                           mortgage on the Member's principal residence.

               (b)   The amount withdrawn may not exceed the actual expense
                     incurred or to be incurred by the Member on account of such
                     needs. The amount of an immediate and heavy financial need
                     may include any amounts necessary to pay any federal,
                     state, or local income taxes or penalties reasonably
                     anticipated to result from the distribution. The amount may
                     be withdrawn only to the extent that the need cannot be
                     satisfied by other resources reasonably available to the
                     Member.

                     In making this determination, the Plan Administrator may
                     rely on the Member's representation that the need cannot be
                     relieved:

                     (1)   Through reimbursement or compensation by insurance or
                           otherwise;

                     (2)   By reasonable liquidation of the Member's assets;

                     (3)   By other distributions or loans from Company-
                           sponsored plans, or

                                       33

                     (4)  By borrowing from commercial sources on reasonable
                          terms.

               (c)   Only one such withdrawal shall be permitted during a
                     twelve-month period.

               (d)   The maximum amount which may be withdrawn is the sum of:

                     (i)   The dollar amount of Basic Contributions made on
                           behalf of such Member (but excluding income thereon);

                     (ii)  The balance of his Company Matching Contributions
                           Account, provided he is fully vested in his Company
                           Matching Contribution Account; and

                     (iii) The balance of the Member's Basic Investment Account
                           under the Prior Plan.

               (e)   The withdrawal shall be paid to the Member as soon as
                     practicable after the Member's written request is submitted
                     to the Plan Administrator.

               (f)   A Member receiving a hardship withdrawal shall be precluded
                     from making any Basic Matched Contributions, Basic
                     Unmatched Contributions, and Supplemental Contributions
                     during the twelve (12) month period immediately following
                     such withdrawal.

               contributions and related earnings) in accordance with guidelines
               determined by the Plan Administrator. Payment shall be made to
               the Member as soon as practicable after submission of the

                     calendar year by submitting a request to the Plan
                     Administrator in accordance with guidelines determined by
                     the Plan Administrator.

               (b)   Matching Contributions shall be suspended for six months if
                     a Member withdraws any or all of his Matching Contributions

                     Investment Account and Rollover Account.

               (b)   Once a Member has withdrawn all amounts, if any, in his
                     Supplemental Investment Account and Rollover Account, he
                     must then withdraw amounts from his Company Contribution
                     Account under Section 11.04. Withdrawals from his Company
                     Contribution Account shall be made first from Company
                     Contributions that have been credited to his Account for at
                     least two years preceding the withdrawal.

               (c)   When a Member has withdrawn all amounts available as
                     described in paragraphs (a) and (b), then the Member may
                     withdraw amounts in a hardship withdrawal from his Basic
                     Investment Account, provided he satisfies the requirements
                     of Section 11.02.

                     attainment of age sixty-five (65) for reasons other than
                     Retirement, Disability or death, the portion, if any, of
                     his Company Matching Contribution Account in which he is
                     not vested pursuant to Article VIII shall be forfeited as

               (b) If a Member has forfeited a portion of his Company
                   Contribution Account pursuant to subsection (a), such
                   forfeited amount will be restored if he is re-employed by the
                   Company before he has incurred a Break in Service of at least
                   five (5) years. Any amounts restored and repaid to the Trust
                   Fund under this Section shall be paid into the remaining

                   The permissible sources for restoring forfeitures shall be
                   income or gain to the Plan, forfeitures, or Company
                   contributions (without regard to the existence of profits).

               --------------------------
               application of the provisions of Section 12.01 shall be used to

Section 13.03  Authority and Duties of Various Fiduciaries.
               -------------------------------------------

               (a)   Except for matters required by the terms of the Plan, or of
                     the Trust to be decided by the Trustee, the Plan
                     Administrator shall have the exclusive right to interpret
                     the Plan and to decide any and all matters arising under
                     the Plan or in connection with its administration,
                     including determination of eligibility for, and the amount
                     of distributions and withdrawals. The Company shall have no
                     power to direct or modify any interpretations,
                     determinations, or decisions of the Plan Administrator. The
                     Plan Administrator may recommend amendments to the Board of
                     Directors. The Plan Administrator may from time to time
                     adopt rules for the administration of the Plan and the
                     conduct of its business, which rules shall be consistent
                     with the provisions of the Plan.

               (b)   The Plan Administrator, the Trustee, the Benefits Council,
                     and any other named fiduciary may each employ counsel,
                     agents, and such clerical and accounting services as it may
                     require in carrying out its responsibilities under the
                     Plan. All fiduciaries shall be entitled to rely upon
                     tables, valuations, certificates, opinions, and reports
                     furnished by any actuary, accountant, or legal counsel
                     appointed under the provisions of the Plan.

               (c)   The Plan Administrator shall keep in convenient form such
                     personnel data as may be necessary for the Plan. The Plan
                     Administrator shall prepare, distribute, and file such
                     reports and notices as may be required by applicable law or
                     regulations.

               (d)   The Plan Administrator shall control and manage the Plan
                     assets to the extent it has not delegated its power to do
                     so. Such delegation of power may include the right to
                     appoint and remove investment managers and Trustees. Such
                     delegation may be accomplished by a separate instrument or
                     by appropriate provisions in the Trust.

               (e)   The members of the Plan Administrator, and the Trustee
                     shall use that degree of care, skill, prudence and
                     diligence that a prudent person acting in a like capacity
                     and familiar with such matters would use in his conduct of
                     a similar Situation. A member of the Plan Administrator, or
                     the Trustee shall not be liable for the breach of fiduciary
                     responsibility of another fiduciary unless (1) he
                     participates knowingly in, or knowingly undertakes to
                     conceal, an

                                       38
<PAGE>

                     act or omission of such other fiduciary, knowing such act
                     or omission is a breach; or (2) by his failure to discharge
                     his duties solely in the interest of Members and
                     Beneficiaries for the exclusive purpose of providing their
                     benefits and defraying reasonable expenses of administering
                     the Plan not met by the Company, he has enabled such other
                     fiduciary to commit a breach; or (3) he has knowledge of a
                     breach by such other fiduciary and does not make reasonable
                     efforts to remedy the breach; or (4) if the Plan
                     Administrator, or the Trustee improperly allocates among
                     themselves or delegates to others, or fails to properly
                     review such allocation or delegation of fiduciary
                     responsibilities.

               (f)   The Company will indemnify and save harmless the members of
                     the Plan Administrator, the Trustee, and any person to whom
                     fiduciary responsibilities are delegated under this Plan
                     against any and all expenses (including attorneys' fees),
                     judgments, fines, and amounts paid in settlement, actually
                     and reasonably incurred by him in connection with any
                     civil, criminal, administrative, or investigative action,
                     proceeding, or claim (including an action by or in the
                     right of the Company) by reason of the fact that he is or
                     was serving in such capacity, provided that such person's
                     conduct is not finally adjudged to have been knowingly
                     fraudulent, deliberately dishonest or willful misconduct.

               (g)   Each Trustee shall maintain accounts showing the fiscal
                     transactions of the Trust established hereunder. The
                     Company shall keep in convenient form such financial data
                     as may be necessary for the Plan, and shall annually cause
                     to be prepared a balance sheet and statement of financial
                     transactions of the Plan and the Trust.

               (h)   Whenever, in the administration of the Plan, any
                     discretionary action is required, the authorized party
                     shall exercise his authority in a nondiscriminatory manner
                     so that all persons similarly situated will receive
                     substantially the same treatment.

Section l3.04  Named Fiduciaries.
               -----------------

               (a)   The Board of Directors, the Plan Administrator, and shall

                     appointed as a named fiduciary by the Board of Directors by
                     resolution or appointed by an appropriate instrument
                     executed by an officer of the Company thereunto authorized
                     by resolution of the Board of Directors, shall also
                     constitute a named fiduciary in respect of the duty
                     delegated to him or it in such resolution or instrument.

Section 13.05  Delegation.  Any named fiduciary designated herein or appointed
               ----------
               as provided herein, unless precluded from doing so by the terms
               of such appointment, may by appropriate instrument designate any
               person (including any firm or corporation) to carry out part or
               all of such fiduciary's responsibilities and upon such
               designation the named fiduciary shall have no liability, except
               as imposed by applicable law, for any act or omission of such
               person. The foregoing does not preclude any other fiduciary to
               the extent allowed by ERISA and the terms of his appointment from
               delegating part or all of such fiduciary's responsibilities with
               respect to the Plan.

               retroactively and prospectively, modify or amend, in whole or in
               part, any or all of the provisions of the Plan, including any
               modification in the Plan or in the agreement or agreements

               necessary or advisable in order to obtain the qualification or
               exemption, or to maintain the qualification or exemption of the
               Plan and the Trust under the Code to comply with ERISA, provided,
               however, that no such modification or amendment shall make it
               possible for any part of the funds of the Plan to be used for, or
               diverted to, purposes other than for the exclusive benefit of
               Members, spouses, former Members, retired Members or
               Beneficiaries under the Plan; that no modification or amendment
               shall be made which has the effect of decreasing retroactively
               the Accounts of any Member or of reducing the non-forfeitable
               percentage of the Company Matching Contribution Account of a

               discontinuance of contributions hereunder by all or any of the
               participating companies for any reason at any time. In case of
               such termination or complete discontinuance of contributions
               hereunder, there shall automatically vest in the appropriate

               merged or consolidated with, nor may its assets or liabilities be
               transferred to, any other plan unless each Member, spouse, former
               Member, retired Member or Beneficiary under the Plan would, if
               the resulting plan were then terminated, receive a benefit
               immediately after the merger, consolidation, or transfer which is
               equal to or greater than the benefit he would have been entitled
               to receive immediately before the merger, consolidation, or
               transfer if the Plan had been terminated.

Section 15.01  Loans.  In the event of financial necessity, a Member may make
               -----
               application to the Plan Administrator in writing to borrow from
               the Trust Fund and the Plan Administrator may in its sole
               discretion permit such a loan upon the conditions hereinafter
               specified. The authority herein granted to the Plan Administrator
               to approve loans from the Trust Fund is for the purpose of
               assisting a Member to meet special situations and shall not be
               used as a means of distributing benefits before they otherwise
               become due. Loans shall be granted in a uniform and non-
               discriminatory manner and shall be made on the following
               conditions:

               (a)  The amount of a loan to a Member (when added to the
                    outstanding balance of all other loans from the Plan to the
                    Member) shall not exceed the lesser of --

<PAGE>

                    (1)  Fifty percent (50%) of the vested amount in the
                         Member's Accounts, or

                    (2)  $50,000, reduced by the excess (if any) of the highest
                         outstanding balance of loans from the Plan to the
                         Member during the one-year period ending on the day
                         before the date on which such loan was made over the
                         outstanding balance of loans from the Plan on the date
                         on which such loan was made.

                         The maturity of a loan shall not exceed five (5) years,
                         except in the case of a loan to acquire or construct
                         the Member's principal residence, which shall mature in
                         not more than ten (10) years.

                         If the Member is also covered under another qualified
                         plan maintained by the Company, the limitations of
                         subsections (a)(l) and (2) shall be applied as though
                         all such qualified plans are one plan.

               (b)  A note shall be signed by the Member establishing regular
                    installment payments made by payroll deduction whenever
                    possible and to the extent permitted by law. The terms of
                    such loans shall require substantially level amortization
                    over the term of the loan with payments not less frequently
                    than quarterly. Loans shall bear interest as specified in

               including distributions required or permitted by the qualified

               service and which commence before the Member has attained the
               earliest retirement age under the Plan; provided, however, the

               his claim on or before the ninetieth (90th) day following the

               additional time for processing the claim, the Benefits Council
               may delay issuing its statement or notice for an additional
               ninety (90) days provided that the Member or Beneficiary is
               notified of the circumstances necessitating the delay and the
               date the Committee expects to render its final opinion. A claim
               for benefits is not effective unless filed on forms prescribed by
               the Benefits Council. Each notice of whole or partial denial of
               claimed benefits shall set forth the specific reasons for the
               denial, the time within which an appeal must be made by the

Section 17.02  Review.  Each Member or Beneficiary whose claim for benefits has
               ------
               been wholly or partially denied shall have such rights to review

               Council to review such denial; such request shall be made on
               forms prescribed by the Benefits Council. A request for review
               shall be filed by the Member or Beneficiary or his duly
               authorized representative on or before the sixtieth (60th) day
               following the earlier of the Member or Beneficiary's receipt of
               notice of denial of his claim or the expiration of the prescribed
               period for issuing a statement of benefits or notice of denial.
               The Benefits Council shall issue a written statement on or before
               the sixtieth (60th) day following its receipt of such request
               stating the Benefits Council's decision on review and the reasons
               therefor, including specific references to pertinent Plan
               provisions on which the decision is based, and any other
               information required by applicable law. If special circumstances
               require additional time for processing such review, the Benefits
               Council may delay issuing its decision for an additional sixty
               (60) days provided that the Member or Beneficiary is notified of
               such circumstances and the date the Benefits Council expects to
               render its final decision. If the decision is not issued within
               the prescribed period, the appeal shall be deemed denied. No
               Member or Beneficiary shall have recourse to courts of law until
               the administrative review process set forth herein has been
               completed.

                    compensation as defined in Treas. Reg. (S)1.415-2(d) (or any
                    regulation which replaces or supersedes such regulation) for
                    purposes of the limitations on benefits and contributions
                    under qualified plans.

               (g)  If, for any Plan Year, it is necessary to limit the
                    allocation of an amount to a Member's Account to comply with
                    subsection (a), the Plan shall limit such allocation by
                    reducing contributions in the following order --

                    (1)  first, to the extent necessary, Supplemental
                         Contributions and any earnings thereon;

                    (2)  second, to the extent necessary, the Basic Unmatched
                         Contributions, if any, made on his behalf and any
                         earnings thereon;

                    (3)  third, to the extent necessary, the amount of the Basic
                         Matched Contributions made on his behalf and any
                         earnings thereon. The Company Matching Contributions
                         made with respect to such Basic Matched Contributions
                         and any earnings

                         thereon shall be treated as though they were
                         forfeitures to the extent necessary and as soon as
                         administratively feasible; and

                    (4)  fourth, to the extent necessary, other Company or
                         Commonly Controlled Entity contributions made to other
                         qualified defined contribution plans.

                         If the limitations of subsection (b) are exceeded, the
                         accrued benefit of the Member under the defined benefit
                         plan shall be reduced to the extent necessary to
                         satisfy the requirements of subsection (b).

                              Top-Heavy Provisions
                              --------------------

Section 19.01  Application of Top-Heavy Provisions.
               -----------------------------------

               (a)  Except as provided in subsection (b)(2), if as of a
                    Determination Date, the sum of the amount of the Section 416
                    Accounts of Key Employees and the Beneficiaries of deceased
                    Key Employees exceeds sixty percent (60%) of the amount of
                    the Section 416 Accounts of all Members and Beneficiaries,
                    the Plan is top-heavy and the provisions of this Article
                    shall become applicable.

                    If any individual has not received any compensation (other
                    than benefits under a plan) from the Company or a Commonly
                    Controlled Entity of the Company at any time during the
                    five-year period ending on the Determination Date, the
                    Section 416 Account of such individual or his Beneficiary
                    shall be excluded from all computations under this Article
                    with respect to Plan Years beginning after December 31,
                    1984. However, if such an individual returns to employment
                    with the Company or Commonly Controlled Entity, his Section
                    416 account shall be included in calculations under this
                    section. The Section 416 Account of an individual who was a
                    Key Employee but is not a Key Employee for the Plan Year
                    containing the Determination Date and the preceding four
                    Plan Years or the Section 416 Account of the Beneficiary of
                    such an individual shall be excluded from all computations
                    under this Article.

            (b)   (1) If as of a Determination Date this Plan is part of an
                  Aggregation Group which is top-heavy, the provisions of this
                  Article shall become applicable. Top-heaviness for the purpose
                  of this subsection shall be determined with respect to the
                  Aggregation Group in the same manner as described in
                  subsection (a) except that if the Aggregation Group includes a
                  defined benefit plan, the Section 416 Account shall include
                  the present value of the accrued benefit of a member or a
                  beneficiary under such plan.

                  (2) If this Plan is top-heavy under subsection (a), but the
                  Aggregation Group is not top-heavy, this Article shall not be
                  applicable.

            (c)   The Plan Administrator shall have responsibility to make all
                  calculations to determine whether this Plan is top-heavy. The
                  Plan Administrator may use a method which approximates the
                  calculations described in Section 19.01(a) provided that it
                  mathematically proves that the Plan is not top-heavy, such as
                  a method which overstates the Section 416 Accounts with
                  respect to Key Employees and understates the Section 416
                  Accounts with respect to non-Key Employees.

Section 19.02 Definitions.
              -----------

            (a)   "Aggregation Group" means this Plan and all other plans
                  (including a frozen plan) maintained by the Company which
                  covers a Key Employee or his Beneficiary and any other plan
                  which enables a plan covering a Key Employee or his
                  Beneficiary to meet the requirements of Code Sections
                  401(a)(4) or 410. A terminated plan shall be included in an
                  Aggregation Group if it was maintained by the Company within
                  the last five (5) years ending on the Determination Date for
                  the Plan Year in question and would, but for the fact it was
                  terminated, meet the conditions of the preceding sentence. In
                  addition, at the election of the Plan Administrator, the
                  Aggregation Group may be expanded by the company if such
                  expanded Aggregation Group meets the requirements of Code
                  Sections 401(a)(4) and 410.

            (b)   "Determination Date" means the last day of the Plan Year
                  immediately preceding the Plan Year for which top-heaviness is
                  to be determined.

                      calendar year in which the Plan Year ends; provided,
                      however, that no more than the lesser of --

            (A)   50 Employees, or

            (B)   the greater of (i) three Employees or (ii) ten percent (10%)
                  of the greatest number of employees of the company and its
                  Commonly Controlled Entities for the Plan Year containing the
                  Determination Date and the preceding four Plan Years shall be
                  treated as officers, and such officers shall be those with the
                  highest annual Compensation in the five-year period;

                  (2) one of the ten Employees having an annual Compensation in
                      excess of the amount in effect under Code Section
                      415(c)(1)(A) and owning (or considered as owning within
                      the meaning of Code Section 318) both more than one-half

                      For the purpose of subsection (c)(l)(B)(II), if ten
                      percent (10%) of the number of Employees is not an
                      integer, the number shall be increased to the nearest
                      integer. The determination as to whether a person is an of
                      ricer shall be made on the basis of his actual authority
                      and duties and without regard to his title. For the
                      purpose of

<PAGE>

                      subsection (c)(2), if two Employees have the same interest
                      in the Company, the Employee having the greater annual
                      Compensation from the Company, shall be treated as having
                      a larger interest. For the purpose of subsections (c)(3)
                      and (c)(4), ownership shall be determined in accordance
                      with Code Section 416 (i)(l)(B) and (C).

                      the Determination Date (or his account under another
                      qualified defined contribution plan which is part of an
                      Aggregation Group) including uncontributed amounts due as
                      of such Valuation Date but which are actually contributed

                      Date, including a distribution under a terminated plan
                      which, if it had not been terminated, would have been

                      which is a tax-free rollover contribution (or similar
                      transfer) that is not initiated by the Member or that is
                      contributed to a plan which is maintained by the Company;
                      reduced by --

                  (4) the amount of a rollover contribution (or similar
                      transfer) which is accepted by this Plan (or a plan

Section 19.03  Minimum Contribution.
               --------------------

               (a)    If this Plan is determined to be top-heavy under the
                      provisions of Section 19.01, with respect to each Member
                      who is not a Key employee and is an Employee on the last
                      day of the Plan Year, the sum of Employer Contributions
                      (other than Basic Contributions), forfeitures treated as
                      Employer Contributions under this Plan, and under all
                      qualified defined contribution plans in the Aggregation
                      Group shall not be less than three percent (3%) of such
                      Member's Compensation [as defined in Section 18.01(f)].
                      Notwithstanding the provisions of Section 8.02,
                      contributions made pursuant to this Section shall be fully
                      vested at all times. This Section shall not be applicable
                      with respect to a Member who is also covered under a
                      defined benefit plan maintained by the Company which
                      provides the benefit specified by Code Section 416(c)(1).

               (b)    The contribution rate specified in subsection (a) shall
                      not exceed the percentage at which Employer Contributions
                      and forfeitures are allocated under the Plan or the plans
                      of the Aggregation Group to the account of the Key
                      Employee for whom such percentage is the highest for the
                      Plan Year. For the purpose of this subsection, the
                      percentage for each Key Employee shall be determined by
                      dividing the Employer Contributions and forfeitures for
                      the Key Employee by the amount of his total compensation
                      for the year not in excess of $200,000 [as adjusted by the
                      Secretary of the Treasury under Code Section 416(d)]. This
                      subsection shall not apply if this Plan is required to be
                      included in an Aggregation Group and the Plan enables a
                      defined benefit plan which is part of the Aggregation
                      Group to meet the requirements of Code Section 401 (a)(4)
                      or 410.

Section 19.04  Limit on Annual Additions: Combined Plan Limit.
               ----------------------------------------------

               (a)    If this Plan is determined to be top-heavy under Section
                      19.01, Section 18.01(b) of this Plan shall be applied by
                      substituting 1.0 for 1.25. The transitional rule of Code
                      Section 415(e)(6)(B)(i) shall be applied by substituting
                      "$41,500" for "$51,875".

               (b)    Subsection (a) shall not be applicable if --

<PAGE>

                      (1)  Section 19.03 is applied by substituting "four
                           percent (4%)" for "three percent (3%)", and

                      (2)  this Plan would not be top-heavy if "ninety percent
                           (90%)" is substituted for "sixty percent (60%)" in
                           Section 19.01.

               (c)    If, but for this subsection (c), subsection (a) would
                      begin to apply with respect to the Plan, the application
                      of subsection (a) shall be suspended with respect to a
                      Member so long as there are --

                           (1) no Company contributions, forfeitures, or
                           voluntary nondeductible contributions allocated to
                           such Member, and

                           (2) no accruals under a qualified defined benefit
                           plan for such Member.

     IN WITNESS WHEREOF, Protein Technologies International, Inc. has caused
this amended Plan to be executed by the undersigned representative of the
Company effective as of January 1, 1999, or as otherwise indicated.

                         -----------------------------------------------
          Contributions.
          -------------

          (a)       Each Member may elect to reduce his Compensation in any
                    amount from two percent (2%) to twelve percent (12%) [in one
                    percent (1%) increments] of his Compensation for each
                    payroll period subject to the provisions set forth in
                    Sections 4.04(g), 4.08, and Article XIX, and his Employer
                    shall remit an amount equal to the amount of the reduction
                    in his Compensation to the Plan on his behalf as soon as
                    practicable after the end of the payroll period.

          (b)       For a Member who has (1) completed a one (1) year Period of
                    Service, or (2) was an Eligible Employee on the Effective
                    Date of this Plan, the first six percent (6%) of
                    contributions under this paragraph shall be considered Basic
                    Matched Contributions, and a Company Contribution shall be
                    made with respect to such contributions in accordance with
                    Section 4.02. Any contributions other than those described
                    in the preceding sentence shall be considered Basic
                    Unmatched Contributions.

          (c)       Notwithstanding the foregoing, the Employer shall not remit
                    to the Plan any Basic Matched Contributions or Basic
                    Unmatched Contributions on behalf of any Member who receives
                    a hardship withdrawal of his Basic Contribution Account or
                    his Company Matching Contribution Account in accordance with
                    Section 11.02, during the twelve-month period immediately

          Section 4.02  Company Matching Contributions.
                        ------------------------------

          (a)       The Company shall contribute out of its accumulated earnings
                    and profits to a Company Matching Contribution Account an
                    amount equal to 100% of each Member's Basic Matched
                    Contributions.

          (b)       In the event that the Commissioner of Internal Revenue, on
                    timely application made after the adoption of the Plan, as
                    restated, determines that the Plan and the implementing
                    trust do not qualify for tax-exempt status, or refuses, in
                    writing, to issue a favorable determination with respect to
                    the Plan and such trust, the Employer contributions made on
                    or after the date on which such determination or refusal is
                    applicable shall be returned to the Employer without
                    interest. In the event that an Employer contribution to the
                    Plan is made by a mistake of fact or all or part of the
                    Employer's deductions under Code Section 404 for
                    contributions to the Plan are disallowed by the Internal
                    Revenue Service, the portion of the contributions
                    attributable to such mistake of fact or to which such
                    disallowance applies shall be returned to the Employer
                    without interest.

                    Any such return shall be made within one year after the
                    making of such contribution by mistake of fact or the denial
                    of qualification or disallowance of deductions, as the case
                    may be.

          (c)       Company Matching Contributions shall be suspended for six
                    months if a Member withdraws any or all of his Company
                    Matching Contributions deposited in his Account during the
                    two years preceding the withdrawal under Section 11.04."

                    Compensated Employees for the preceding Plan Year,

                    deferral percentage for the eligible Highly Compensated
                    Employees may not exceed the actual deferral percentage for

                    contributions to the Plan for a specified group of Employees
                    for a Plan Year shall be the average of the ratios
                    (calculated separately for each Employee in such group) of:

                    (i)  The sum of each of the following which are actually

                  manner in which voting rights with respect to shares or units
                  represented by the Member's Account are to be exercised. The
                  Trustee shall vote the number of shares in accordance with

                  of E.I. du Pont de Nemours Investment Fund, any such
                  instructions shall remain

                    voting instructions, as applicable.

          (b)       Each Member shall be entitled to direct the Trustee as to

                    portion of the Member's Account invested in the DuPont
                    Common Stock Fund. The Trustee shall tender such shares in
                    accordance with such instructions. If a Member does not
                    return proper tender instructions to the Trustee in a timely
                    manner, such inaction by the Member shall be deemed a
                    decision not to tender, and the Trustee shall not tender
                    with respect to such Member's Account."

                  amounts may be invested in this Fund other than as a result of
                  such initial tender offer.  Notwithstanding any other
