     be equal to any whole percentage of his or her Compensation, as the
     Participant shall elect, except that this whole percentage shall not exceed
     15 percent of his or her Compensation. Participant Elected Contributions
     shall be made through payroll deductions from the Participant's
     Compensation. If a Participant elects to make Participant Elected
     Contributions, the contributions shall be deemed to be employer
     contributions to the Plan for federal income tax purposes and, to the
     extent permitted, for purposes of other federal, state and local taxes. A
     Participant's election to make Participant Elected Contributions shall
     constitute an election to have the Participant's taxable salary or wages
     from the Participating Company reduced by the amount of the Participant
     Elected Contributions.

4.2  Suspension, Change and Resumption of Participant Elected Contributions.  A
     ----------------------------------------------------------------------
     Participant may elect to suspend or change the rate of Participant Elected
     Contributions and, having elected to suspend Participant Elected
     Contributions, may elect to resume them. Any such election shall be made by
     following the procedures prescribed by the Company, which election shall be
     put into effect at the time prescribed by the Company's procedures.

4.3  Contributions to the Trustee.  The Participating Companies shall forward
     ----------------------------
     all Employee Contributions to the Trustee, for investment in the Trust
     Fund, as soon as administratively possible after they were withheld.
     Employee Contributions shall be credited to each Participant's Accounts as
     provided in Sections 6.3 and 6.4.

4.4  Limits on Participant Elected Contributions.  This Section briefly
     -------------------------------------------
     describes the rules that limit the amount of Participant Elected
     Contributions that may be contributed to a Participant's Account for the
     Plan Year or calendar year.

     (a)  Compensation Limit. A Participant may not make further Participant
          ------------------
          Elected Contributions for the Plan Year once his or her Compensation
          reaches the Compensation Limitation.

     (b)  Annual Deferral Limit.  As is described in detail in Article 13, a
          ---------------------
          Participant's Participant Elected Contributions, together with certain
          other elective deferrals, made during a calendar year may not exceed
          the Annual Deferral Limit, as defined in Section 13.9(b).

     (c)  Average Deferral Percentage Limit. As is described in detail in
          ---------------------------------
          Article 13 and Article 15, Participant Elected Contributions may be
          returned to certain Participants who are Highly Compensated Employees
          in the event that the average deferral percentage test or multiple-use
          test is not met for the Plan Year.

                                       10
<PAGE>

     (d)  Section 415 "Annual Additions" Limit. As is described in detail in
          ------------------------------------
          Article 16, if amounts credited to a Participant's Accounts during the
          Plan Year, other than earnings and Rollover Contributions, exceed the
          lesser of $30,000 or 25% of the Participant's Section 415
          Compensation, then Participant Elected Contributions may be returned
          to the Participant.

     (e)  Prospective Limitations. In order to ensure compliance with the
          -----------------------
          average deferral percentage test, the multiple-use test and the annual
          additions limit, at any time during the Plan Year and at its sole
          discretion, the Company may require any Participant to discontinue or
          reduce the rate of his or her Participant Elected Contributions. The
          Company may require the discontinuance or reduction in the rate of
          Participant Elected Contributions even if its actions may prevent a
          Participant from making the maximum Participant Elected Contributions
          allowed by law.

     (f)  Nondeductible and Mistaken Contributions. As is described in detail in
          ----------------------------------------
          Section 5.6(e), Participant Elected Contributions that are not
          deductible by the Company or that are made by mistake are returned to
          the Company.

4.5  Rollover Contributions.  The Plan may receive Rollover Contributions on
     ----------------------
     behalf of an Eligible Employee if the following conditions are satisfied:

     (a)  The contribution is made entirely in the form of U.S. dollars; and

     (b)  The Eligible Employee demonstrates to the Company's satisfaction that
          the contribution is a qualifying rollover contribution under Section
          402(c)(4), 403(a)(4) or 408(d)(3) of the Code.

     If an Eligible Employee who is not a Participant makes a Rollover
     Contribution, then he or she shall be considered a Participant solely with
     respect to his or her Rollover Contribution Account until he or she becomes
     a Participant for all purposes pursuant to Article 3.

     A Rollover Contribution shall be paid to the Company in a lump sum in cash
     and shall be credited to the Participant's Rollover Account.  The
     Participant may direct the investment of his or her Rollover Account by
     filing the specified investment election form in accordance with such rules
     as may be established by the Company.

ARTICLE 5.  COMPANY CONTRIBUTIONS.
---------------------------------

5.1  Matching Contributions.  Subject to the limitations of Section 5.6 and
     ----------------------
     Articles 13-16, each Participating Company may, in its discretion, make
     Matching Contributions in an amount determined by the Participating
     Company. A

                                       11
<PAGE>

     Matching Contributions formula may limit the amount of Participant Elected
     Contributions that are taken into account for purposes of allocating
     Matching Contributions or may limit allocations of Matching Contributions
     to a specified group of Participants; provided, however, that the Matching
     Contribution formula(s) shall not discriminate in favor of Highly
     Compensated Employees. A Matching Contribution shall be paid to the Trustee
     as soon as reasonably practicable after the pay period to which it relates
     and shall be allocated to the Accounts of Participants as provided in
     Section 6.5.

5.2  Nonelective Contributions.  Subject to the limitations Section 5.6 and
     -------------------------
     Articles 13-16, each Participating Company may, in its discretion, make
     Nonelective Contributions in an amount determined by the Participating
     Company. The Company, in its sole discretion, may determine that the
     allocation of part or all of the Nonelective Contribution for a Plan Year
     shall be limited to the Nonelective Contribution Accounts of Participants
     who remain Eligible Employees on the last day of the relevant Plan Year.
     The Company may limit the amount of Compensation that is taken into account
     for purposes of allocating Nonelective Contributions, and it may determine
     that allocations of Nonelective Contributions shall be limited to a
     specified group of Eligible Employees; provided, however, that the
     Nonelective Contribution formula(s) shall not discriminate in favor of
     Highly Compensated Employees. For purposes of allocating such Nonelective
     Contributions for any Plan Year or other allocation period based on an
     Employee's Compensation, only Compensation attributable to periods in such
     Plan Year or other allocation period during which such Employee was an
     Eligible Employee shall be taken into account. Nonelective Contributions
     shall be paid to the Trustee as soon as reasonably practicable following
     the close of the pay period to which it relates and shall be allocated to
     the Accounts of Participants as provided in Section 6.6.

     Nonelective Contributions may include a core contribution equal to a
     specified percentage of Compensation to be made by the Company for each
     payroll period during the Plan Year.

5.3  Qualified Nonelective Contributions.  The Participating Companies may make
     -----------------------------------
     Qualified Nonelective Contributions pursuant to Article 13.6.

5.4  Qualified Matching Contributions.  The Participating Companies may make
     --------------------------------
     Qualified Matching Contributions in an amount determined by the
     Participating Company. The Participating Company may, in its sole
     discretion, limit the amount of Participant Elected Contributions that are
     taken into account for purposes of allocating Qualified Matching
     Contributions, or it may determine that allocations of Qualified Matching
     Contributions shall be limited to a specified group of Eligible Employees;
     provided, however, that the Qualified Matching Contribution formula(s)
     shall not discriminate in favor of Highly Compensated

                                       12
<PAGE>

     Employees. Qualified Matching Contributions shall be paid to the Trustee as
     soon as reasonably practicable following the date as of which they are
     allocated.

5.5  Investment of Company Contributions.  The Trustee shall invest the Company
     -----------------------------------
     Contributions it receives in accordance with Section 6.2.

5.6  Limits on Company Contributions.  This Section briefly describes the rules
     -------------------------------
     that limit the amount of Company Contributions that may be contributed to a
     Participant's Account for the Plan Year.

     (a)  Compensation Limit.  A Company Contribution that is expressed as a
          ------------------
          percentage of a Participant's Compensation may not be based on
          Compensation in excess of the Compensation Limit in effect for the
          Plan Year.

     (b)  Average Contribution Percentage Limit.  As is described in detail in
          -------------------------------------
          Article 14 and Article 15, Matching Contributions, Qualified Matching
          Contributions or Qualified Nonelective Contributions may be returned
          to certain Participants who are Highly Compensated Employees in the
          event that the average contribution percentage test or multiple-use
          test is not met for the Plan Year.

     (c)  Section 415 "Annual Additions" Limit. As is described in detail in
          ------------------------------------
          Article 16, if amounts credited to a Participant's Accounts during the
          Plan Year, other than earnings and Rollover Contributions, exceed the
          lesser of $30,000 or 25% of the Participant's Section 415
          Compensation, then Company Contributions may be returned to the
          Participant.

     (d)  Prospective Limitations. In order to ensure compliance with the
          -----------------------
          average contribution percentage test, the multiple-use test and the
          annual additions limit, at any time during the Plan Year and at its
          sole discretion the Company may reduce or discontinue allocations of
          Company Contributions to any Participant's Account. The Company may
          implement this reduction or discontinuance of allocations of Company
          Contributions even if its action may prevent a Participant from
          receiving the maximum allocations to his or her Account allowed by
          law.

     (e)  Nondeductible or Mistaken Contributions. Any other provision of the
          ---------------------------------------
          Plan notwithstanding, Company Contributions and Participant Elected
          Contributions are conditioned upon their deductibility under Section
          404 of the Code and the qualification of the Plan under Section 401(a)
          of the Code. If the deductibility of a Company Contribution or
          Participant Elected Contribution is denied, the amount for which a
          deduction is disallowed (reduced by any losses incurred with respect
          to such amount) shall be returned to the Participating Companies
          within one year after the

                                       13
<PAGE>

          disallowance of the deduction. If a Company Contribution or
          Participant Elected Contribution is made to the Plan by reason of a
          mistake of fact, the amount contributed by reason of such mistake
          (reduced by any losses incurred with respect to such amount) shall be
          returned to the Participating Companies within one year after the date
          such contribution was made.

ARTICLE 6.  INVESTMENTS AND PARTICIPANTS' ACCOUNTS.
--------------------------------------------------

6.1  Investment Funds.  All contributions to the Plan made pursuant to Articles
     ----------------
     4 and 5 shall be paid to the Trust Fund established under the Plan. All
     such contributions shall be invested as provided under the terms of the
     Trust Agreement, which may include provision for the separation of assets
     into separate Investment Funds, including a Company Stock Fund.

6.2  Investment of Contributions.  Employee Contributions and Company
     ---------------------------
     Contributions shall be apportioned among one or more of the Investment
     Funds as the Participant may specify according to the procedures prescribed
     by the Company; provided, however, that a Participant may direct a maximum
     of 50 percent of Employee Contributions, Rollover Contributions and Company
     Contributions to be invested in the Company Stock Fund. In the event that a
     Participant fails to make an investment election, contributions allocated
     to his or her Accounts shall be invested in accordance with procedures
     prescribed by the Company. A Participant may elect to change the investment
     instructions with respect to future contributions according to the
     procedures prescribed by the Company.

6.3  Participant Elected Contributions Account.  A Participant's Participant
     -----------------------------------------
     Elected Contribution Account shall consist of his or her Participant
     Elected Contributions, adjusted to reflect transfers and withdrawals from
     such Participant Elected Contributions Account and earnings, gains,
     expenses and losses attributable to the Investment Fund(s) in which the
     contributions are invested.

6.4  Rollover Contributions Account.  A Participant's Rollover Contributions
     ------------------------------
     Account shall consist of his or her Rollover Contributions, adjusted to
     reflect transfers and withdrawals from such Rollover Contributions Account
     and earnings, gains, expenses and losses attributable to the Investment
     Fund(s) in which the contributions are invested.

6.5  Matching Contributions Account.  A Participant's Matching Contributions
     ------------------------------
     Account shall consist of his or her Matching Contributions, adjusted to
     reflect transfers and withdrawals from such Matching Contributions Account
     and earnings, gains, expenses and losses attributable to the Investment
     Fund(s) in which the contributions are invested. Matching Contributions,
     determined under Section 5.1, shall be allocated to the Matching
     Contributions Account of each

                                       14
<PAGE>

     Participant who is entitled to a Matching Contribution pursuant to Section
     5.1. Matching Contributions shall be allocated as of the last day of the
     period for which the Participant received Compensation with respect to
     which the Matching Contribution is made.

6.6  Nonelective Contributions Account.  A Participant's Nonelective
     ---------------------------------
     Contributions Account shall consist of his or her Nonelective
     Contributions, adjusted to reflect transfers and withdrawals from such
     Nonelective Contributions Account and earnings, gains, expenses and losses
     attributable to the Investment Fund(s) in which the contributions are
     invested. The Nonelective Contribution of a Participating Company,
     determined under Section 5.2, shall be allocated to the Nonelective
     Contribution Accounts of each Participant who is an Eligible Employee of
     the Participating Company on the date as of which the Nonelective
     Contribution is allocated. The Nonelective Contribution of a Participating
     Company shall be allocated to each Participant entitled to an allocation of
     such Nonelective Contribution in the proportion that such Participant's
     Compensation, while he or she was an Eligible Employee, bears to the
     Compensation of all Participants entitled to an allocation of the
     Participating Company's Nonelective Contribution. Allocations of
     Nonelective Contributions shall be made as of each payroll period.

6.7  Qualified Nonelective Contributions Account.  A Participant's Qualified
     -------------------------------------------
     Nonelective Contributions Account shall consist of his or her Qualified
     Nonelective Contributions, adjusted to reflect transfers and withdrawals

     expenses and losses attributable to the Investment Fund(s) in which the
     contributions are invested.

     and losses attributable to the Investment Fund(s) in which the
     contributions are invested.

6.9  Transfers Among Investment Funds. A Participant may elect to reapportion
     --------------------------------
     the values of his or her Accounts among Investment Funds by properly
     following procedures prescribed by the Company. The Company's procedures by
     which a Participant may elect to transfer amounts into or out of the
     Company Stock Fund shall be drafted to provide notice to Participants if
     such an election would cause a Participant to have a purchase or sale of
     Company Stock which is not exempt from potential short-swing trading
     profits liability under Section 16(b) of the Exchange Act by virtue of the
     application of Rule 16b-3 (promulgated under Section 16 of the Exchange
     Act) as in effect from time to time. As of the effective date of this
     amended and restated Plan, such liability may arise if such

                                       15
<PAGE>

     election is made by a Participant (or successor in interest) who is an
     officer, director, or greater than 10% stockholder of the Company (within
     the meaning of Section 16 of the Exchange Act and the rules promulgated
     thereunder) within six months following the date of the most recent
     election made under any employee benefit plan sponsored by the Company or
     an Affiliate if (a) both elections involved either an intra-plan transfer
     involving a fund invested in the Company's equity securities or a cash
     distribution from the employee benefit plan to the Participant (or
     successor in interest) funded by a volitional disposition of the Company's
     equity securities, (b) the prior election involved an acquisition of the
     Company's equity securities if the current election involves a disposition
     of the Company's equity securities, or vice versa, and (c) both elections
     are made at the volition of the Participant (or successor in interest) not
     in connection with the Participant's death, disability, retirement,
     termination of employment, or an election which is required to be made
     available under a provision of the Code. Such a volitional election
     (considering without regard as to whether or not any similar elections have
     occurred within six months of such an election) shall be described as a
     "Discretionary Transaction." On and after July 1, 1996, transfers into the
     Company Stock Fund shall be limited so that, after any such transfer, no
     more than 50% of the value of the Participant's aggregate Account is
     invested in the Company Stock Fund. For purposes of carrying out Investment
     Fund transfers, the value of the Accounts shall be determined as of the
     Valuation Date immediately preceding the Participant's transfer election.

6.10 Allocation of Investment Income.  As soon as reasonably practicable after
     -------------------------------
     each Valuation Date, and within 90 days after the removal or resignation of
     the Trustee, the Trustee shall value the assets of the Trust Fund on the
     basis of fair market value as of the Valuation Date (or the day of
     resignation or removal of the Trustee if it is not a Valuation Date). Where
     separate Investment Funds have been established pursuant to Section 6.1,
     the Trustee shall value each such Investment Fund separately.

6.11 Account Statements. As soon as practicable after the last day of each Plan
     ------------------
     Year (and after such other dates as the Company may determine), there shall
     be prepared and delivered to each Participant a written statement showing
     the fair market value of his or her Accounts as of the applicable date and
     such other information as the Company may determine.

ARTICLE 7.  VESTING OF PARTICIPANTS' ACCOUNTS.
----------

7.1  100 Percent Vesting.  A Participant's interest in all of his or her
     -------------------
     Participant Elected Contributions Account, Qualified Matching Contributions
     Account, Qualified Nonelective Contributions Account and Rollover
     Contributions Account shall be 100% vested and nonforfeitable at all times.

                                       16
<PAGE>

7.2  Vesting of Matching Contributions Accounts.
     ------------------------------------------

     (a)  If a Participant's employment with a member of the Affiliated Group is
          terminated after December 31, 1989 and before his or her Normal
          Retirement Age for any reason other than Disability or death, in
          addition to the amounts credited to the Accounts identified in Section
          7.1, the Participant shall be entitled to an amount equal to the
          "vested percentage" of his Matching Contributions Account. Such vested
          percentage shall be determined in accordance with the following
          schedule.

<TABLE>
<CAPTION>
          Years of Service                             Vested

          2 but less than 3                            50%
          3 but less than 4                            75%
          4 or more                                    100%
</TABLE>

     (b)  In all events, a Participant's Matching Contributions Account shall be
          fully vested upon termination of his or her employment with the
          Company on or after attainment of his or her Normal Retirement Age or
          by reason of Disability or death.

7.3  Vesting of Nonelective Contributions Accounts.  In the case of any
     ---------------------------------------------
     individual who becomes an Employee on or after April 1, 1991 (other than a
     temporary employee described in clause (ii) of Section 7.3(a)), he or she
     shall become fully vested in his or her Nonelective Contributions Account
     upon the earlier of his or her completion of five (5) Years of Service or
     his or her termination of employment on or after attainment of his or her
     Normal Retirement Age or by reason of Disability or death. If the
     employment of such a Participant terminates prior to his or her completion
     of five (5) Years of Service, attainment of Normal Retirement Age,
     Disability or death, he or she shall have no vested interest in his or her
     Nonelective Contributions Account.

7.4  Forfeitures.  If a Participant ceases to be an Employee at a time when he
     -----------
     or she is not yet fully vested in his or her Nonelective Contributions
     Account or Matching Contributions Account, the invested amount of his or
     her Nonelective Contributions Account and Matching Contributions Account
     shall constitute a Forfeiture for the Plan Year in which employment
     terminated. Forfeitures shall be applied to reduce Nonelective
     Contributions and Matching Contributions for the Plan Year. If the
     Participant is rehired as an Employee, then the portion of his or her
     Nonelective Contributions Account or Matching Contributions Account that
     constituted a Forfeiture shall be reinstated to the Nonelective
     Contributions

                                       17
<PAGE>

     Account or Matching Contributions Account, as applicable, as of the close
     of the Plan Year in which the rehire occurs, but only if the Participant
     returns to the service of a Participating Company before incurring a Five-
     Year Break in Service. To the extent that Forfeitures for the Plan Year in
     which the Participant is rehired are insufficient to reinstate the rehired
     Participant's Forfeiture, then the appropriate Participating Company shall
     make a special contribution in the amount required to reinstate the
     Forfeiture.

     If a Participant who was not fully vested at the time of his or her
     termination of employment receives a distribution out of his or her vested
     Account balance and subsequently returns to a Participating Company's
     service before incurring a Five-Year Break in Service, a separate account
     for the Participant's remaining interest in the Plan as of the time of the
     distribution shall be maintained.  At any time, the Participant's vested
     interest in such account shall be an amount "X" determined in accordance
     with the following formula:

          = P(AB + D) - D

     For purposes of such formula, "P" is the vested percentage at the relevant
     time; "AB" is the account balance at the relevant time and "D" is the
     amount of the prior distribution.

     In the event a Participant's service with a Participating Company
     terminates and no payment of the Participant's nonforfeitable interest is
     made, the forfeitable amount of the Participant's interest shall be
     forfeited after the Participant has incurred a Five-Year Break in Service,
     as of a Valuation Date determined in a uniform and consistent manner by the
     Company.  In the event the Participant returns to the service of a
     Participating Company before incurring a Five-Year Break in Service, the
     Participant's Account shall exist as though no forfeiture had taken place.

7.5  Vesting on Reemployment.
     -----------------------

     (a)  Years of Service completed prior to any Break in Service shall not be
          counted in determining a Participant's nonforfeitable interest under
          the Plan if, at the time of the earlier termination of employment, the
          Participant did not have any nonforfeitable interest under the Plan to
          an accrued benefit derived from Nonelective Contributions or Matching
          Contributions and the number of the Participant's consecutive one-year
          Breaks in Service equals or exceeds the greater of five (5) or the
          aggregate number of his or her Years of Service prior to such Break in
          Service.

     (b)  In the case of a Participant who incurs a Five-Year Break in Service,
          Years of Service completed by such Participant after the Five-Year
          Break in Service shall not be counted to increase the Participant's
          nonforfeitable

                                       18
<PAGE>

          interest in his or her Account as determined prior to the Five-Year
          Break in Service.

7.6  Determination of Account Balance.  Whenever a Participant or his or her
     --------------------------------
     Beneficiary is entitled to receive the entire amount or a percentage of his
     or her Account balance, the amount of such balance (including the value of
     any Company Stock held in his or her Account) shall be the amount in (or
     value of) such Account as of the Valuation Date immediately preceding the
     date of distribution.

7.7  Lost Participant or Beneficiary.  In the event that a Beneficiary or
     -------------------------------
     Participant cannot be located at the time a benefit is payable from the
     Plan to him or her, then at the close of the 12-consecutive-month period
     following the date on which the amount became payable, the amount shall be
     treated as a Forfeiture. Such a Forfeiture shall nevertheless be
     reinstated, without interest, if the Participant or Beneficiary
     subsequently is located and makes a valid claim for the benefit.

ARTICLE 8.  DISTRIBUTION OF PLAN BENEFIT.
----------------------------------------

8.1  General Rule.  All distributions under the Plan shall be made in accordance
     ------------
     with the Treasury Regulations under Section 401(a)(9) of the Code,
     including Treasury Regulation Section 1.401(a)(9)-2 or its successor. Such
     regulations are incorporated in the Plan by reference and shall override
     any inconsistent provisions of the Plan.

8.2  Events Permitting Distribution.  No distribution may be made of any amounts
     ------------------------------
     credited to a Participant's Account except:

     (a)  After the Participant's death, Disability or termination of employment
          for any other reason;

     (b)  On or after termination of the Plan, provided that (i) neither the
          Participating Company nor any Affiliate of the Participating Company
          maintains a successor defined contribution plan (other than an
          employee stock ownership plan) and (ii) the Participant's distribution
          is made in the form of a lump sum;

     (c)  On or after the disposition, to an entity that is not an Affiliate of
          the Participating Company, of substantially all of the assets used by
          the Participating Company in a trade or business, but only with
          respect to a Participant who continues employment with the entity
          acquiring such assets, and provided that (i) the Participant's
          distribution is made in the form of a lump sum and (ii) the
          Participating Company continues to maintain the Plan following such
          disposition;

                                       19
<PAGE>

     (d)  On or after the disposition, to an entity that is not an Affiliate of
          the Participating Company, of the interest of the Participating
          Company or an Affiliate of the Participating Company in a subsidiary,
          but only with respect to a Participant who continues employment with
          such subsidiary, and provided that (i) the Participant's distribution
          is made in the form of a lump sum and (ii) the Participating Company
          continues to maintain the Plan following such disposition; or

     (e)  As required by applicable law or in connection with a QDRO, as
          provided in Article 9, or an in-service withdrawal, as provided in
          Article 11.

8.3  Time of Distribution.
     --------------------

     (a)  Except as provided in Sections 8.5, 8.8 and 8.10, and unless a
          Participant elects otherwise, the distribution of a Participant's Plan
          Benefit under Section 8.6 shall occur or commence not later than sixty
          (60) days after the close of the Plan Year in which occurs the later
          of (i) the Participant's attainment of Normal Retirement Age or (ii)
          the Participant's termination of employment. If distribution of a
          Participant's Plan Benefit has not yet occurred, on or about nine (9)
          months before the Participant's Normal Retirement Date, the Company
          shall furnish the Participant with a written explanation of the terms,
          conditions and forms of distributions available from the Plan
          including, where applicable, a general description of the Lifetime
          Annuity (as defined in Section 8.7), and with a description of the
          procedures for electing a form of distribution.

     (b)  A Participant may elect to receive or commence receipt of his or her
          Plan Benefit at any reasonable time after termination of employment.
          If the Participant elects to receive his or her Plan Benefit,
          distribution shall in any event commence not later than one (1) year
          after the end of the Plan Year (i) in which he or she terminates
          employment after attaining Normal Retirement Age or due to Disability,
          or (ii) which is the fifth Plan Year following the Plan Year in which
          he or she otherwise terminates employment (except by reason of his or
          her death). An election under this Subsection must be made in writing,
          must be made not more than ninety (90) days before the date the
          distribution is to occur or commence and must not be made before the
          Participant receives a written notice describing the material features
          and explaining the relative values of the optional forms of benefit
          available under the Plan, in a manner that would satisfy the notice
          requirements of Section 417(a)(3) of the Code. Not less than thirty
          (30) days and not more than ninety (90) days before the Participant's
          distribution is to occur or commence, the Company shall provide the
          Participant with such a written notice, which also shall inform

                                       20
<PAGE>

          the Participant of his or her right (if applicable) to defer receipt
          of his distribution until Normal Retirement Age.

8.4  Amount of Plan Benefit.  A Participant's Plan Benefit shall consist of the
     ----------------------
     Participant's entire interest in his or her Accounts, to the extent vested.

8.5  Latest Time of Distribution. In no event shall a Participant's Plan Benefit
     ---------------------------
     be distributed later than the April 1 next following the calendar year in
     which the Participant attained age 70 1/2 if the Participant is not then an
     Employee.

8.6  Forms of Distribution.
     ---------------------

     (a)  A Participant's Plan Benefit shall be distributed in any of the
          following forms that he or she elects; provided, however, that only a
          Participant who has an Hour of Service prior to April 1, 1996 may
          elect a Lifetime Annuity described in Paragraph (5):

          (1)  A single sum cash distribution;

          (2)  A single sum distribution in full shares of Company Stock (with
               the value of any fractional share paid in cash);

          (3)  A single sum distribution paid in a combination of cash and full
               shares of Company Stock;

          (4)  Cash installments paid at least annually over a period certain
               not exceeding the life expectancy of the Participant or the joint
               life expectancy of the Participant and his or her designated
               Beneficiary. All life expectancies shall be determined not later
               than the date when payments commence and shall not be
               redetermined thereafter. The amount of each installment payment
               shall be determined by dividing the remaining years in the period
               certain by the value of the Participant's Account; or

          (5)  Subject to the provisions of Section 8.7, a nontransferable
               annuity contract that provides for annuity payments at least
               annually over the lifetime of the Participant or the joint
               lifetimes of the Participant and his or her designated
               Beneficiary, and that may provide for a "period certain" feature
               (a "Lifetime Annuity").

     (b)  If, by the time for the distribution of a Participant's Plan Benefit
          in accordance with the foregoing provisions of this Article 8, the
          Participant has not made any election as to the form of the
          distribution, payment of his or her Plan Benefit shall be made in the
          form of a single sum cash distribution.

                                       21
<PAGE>

     (c)  To the extent that a distribution is to be made in a number of shares
          of Company Stock that exceeds the number of shares in the
          Participant's Account under the Company Stock fund, amounts in one or
          more other Investment Funds comprising the Participant's Account shall
          be applied to purchase the required additional shares of Company Stock
          at their fair market value at the time of purchase.

     (d)  The Company shall establish procedures to notify a Participant (or
          successor in interest) if any election regarding the form or timing of
          distribution of benefits from the Plan involving the Company Stock
          Fund constitutes a Discretionary Transaction (as defined in Section
          6.9) which may trigger short-swing trading profits liability for the
          Participant (or successor in interest) under Section 16(b) of the
          Exchange Act. In such an event, the person making the election shall
          be provided with a reasonable opportunity to modify, delay, or revoke
          such an election.

8.7  Lifetime Annuities.  This Section shall apply to any Participant with an
     ------------------
     Hour of Service prior to April 1, 1996, who elects a Lifetime Annuity. The
     Plan Benefit of a Participant who elects to receive a Lifetime Annuity, as
     provided in Section 8.6(a)(5) above, shall be distributed to the
     Participant in the applicable form of annuity described in Subsection (a)
     below, unless, prior to the Annuity Starting Date (as defined in Subsection
     (d) below) with respect to such Lifetime Annuity distribution, the
     Participant elects to waive such Lifetime Annuity, in which case he or she
     may elect any other form of distribution provided under Section 8.6. A
     married Participant may waive the Qualified Joint and Survivor Annuity once
     he or she elects a Lifetime Annuity only as provided in Subsection (b)
     below. If the Participant dies before his or her Annuity Starting Date, the
     provisions of Section 8.9 shall apply.

     (a)  Lifetime Annuity Forms.
          ----------------------

          (1)  In the case of a Participant who is legally married on his or her
               Annuity Starting Date, the normal form of Lifetime Annuity that
               applies shall be a Qualified Joint and Survivor Annuity.

          (2)  In the case of a Participant who is not married on his or her
               Annuity Starting Date, the normal form of Lifetime Annuity that
               applies shall be a Single Life Annuity.

     (b)  Waiver of Lifetime Annuity.
          --------------------------

          (1)  Not more than ninety (90) days before the Annuity Starting Date,
               a married Participant who elects to receive a Lifetime Annuity
               may elect to waive the Qualified Joint and Survivor Annuity form
               of benefit and to receive payment instead in one of the other
               forms

                                       22
<PAGE>

               specified in Section 8.6(a)(l)-(4) or as a Single Life Annuity.
               If the Participant elects the form of benefit in Section
               8.6(a)(4), he or she also may designate a Beneficiary other than
               his or her spouse to receive any benefits payable following his
               or her death. A Participant may revoke any election previously
               made under this Subsection and may make a new election hereunder
               any number of times before his or her Annuity Starting Date. A
               Participant's election or revocation under this Subsection shall
               be in writing.

          (2)  An election by a Participant who elects to receive a Lifetime
               Annuity to waive the Qualified Joint and Survivor Annuity shall
               not be valid unless the Participant has received the notice and
               explanation described in Subsection (c) below and the spouse of
               the Participant consents in writing to such election in a manner
               that satisfies the spousal consent requirements set forth in
               Section 8.13, provided that the Participant's election also must
               designate a specific alternative form of benefit (as well as a
               Beneficiary) that may not be changed without further spousal
               consent (unless expressly permitted by the spouse's consent or a
               prior consent). Spousal consent is not required in order for a
               Participant to reinstate an election to receive a Qualified Joint
               and Survivor Annuity, but is required for any subsequent
               revocation of the election.

     (c)  Notice and Explanation Requirements. Not more than ninety (90) and not
          -----------------------------------
          less than thirty (30) days before the Annuity Starting Date, the
          Company shall notify the Participant in writing of his or her right to
          elect to waive the normal form of Lifetime Annuity. Such written
          notification shall include:

          (1)  An explanation of the terms and conditions of the normal form of
               Lifetime Annuity, including the circumstances under which it will
               be provided if no election is made to waive such form of benefit;

          (2)  A statement of the Participant's right to make an election to
               waive the normal form of Lifetime Annuity and an explanation of
               the effect of such an election;

          (3)  A statement of the Participant's right to revoke an election to
               waive the normal form of Lifetime Annuity and an explanation of
               the effect of such a revocation;

          (4)  A statement of the right, if any, of the Participant's spouse to
               consent to the Participant's election to waive the normal form of

                                       23
<PAGE>

               Lifetime Annuity and to the Participant's designation of an
               alternative form of benefit or Beneficiary;

          (5)  A general explanation of the relative financial impact of an
               election to waive the normal form of Lifetime Annuity;

          (6)  A general description of the material features (including
               eligibility conditions) and an explanation of the relative values
               of the alternative forms of benefit available under the Plan; and

          (7)  A statement regarding the availability of the additional
               information described below in this Subsection (c).

          Within thirty (30) days after receipt of a timely written request from
          the Participant for additional information, the Company shall provide
          the Participant with a written explanation, in nontechnical language,
          of the terms and conditions of the alternative forms of benefit
          available under the Plan and the financial effect (in terms of dollars
          per monthly payment) upon the Participant's monthly benefit in case of
          an election to waive the normal form of Lifetime Annuity and receive
          an alternative form of benefit.

     (d)  Definition of Annuity Starting Date. For purposes of this Article, the
          -----------------------------------
          term "Annuity Starting Date" shall mean the first day of the first
          period for which an amount is paid as an annuity or, in the case of a
          benefit not payable as an annuity, the first day on which all events
          have occurred that entitle the Participant (or, if applicable, a
          Beneficiary) to receive or commence receipt of the benefit.

8.8  Time of Distribution of Death Benefit.  If a Participant dies before
     -------------------------------------
     receiving his or her Plan Benefit, then the Participant's Beneficiary shall
     be entitled to receive the Plan Benefit pursuant to this Section 8.8.
     (Section 8.12 provides that the surviving spouse of a married Participant
     shall be his or her Beneficiary, unless the Participant, with the spouse's
     consent, has otherwise elected prior to his or her death.) The
     Participant's Plan Benefit shall be distributed to the Participant's
     Beneficiary no later than 12 months after the Participant's death. If,
     however, a married Participant has elected to receive his or her Plan
     Benefit in the form of a Lifetime Annuity in accordance with Section
     8.6(a)(5) and Section 8.7 (and has not subsequently waived such Lifetime
     Annuity) and then dies before the Annuity Starting Date (as defined in
     Section 8.7(d)) with his or her spouse surviving him or her, and if the
     value of the Participant's entire vested Plan Benefit exceeds $5,000, the
     distribution shall not occur or commence until the Participant would have
     attained Normal Retirement Age (had he or she not died), unless an earlier
     distribution is elected by the surviving spouse. In this event, the
     Participant's surviving spouse may elect to receive or commence receipt of
     the Participant's

                                       24
<PAGE>

     death benefit at any reasonable time after the Participant's death. Such an
     election must be made in writing not more than ninety (90) days before the
     date the distribution is to occur or commence. For this purpose, if the
     Participant's vested Plan Benefit at the time a distribution commences
     under an installment option pursuant to Section 8.6(a)(4) or a lifetime
     annuity pursuant to Section 8.7 exceeds $5,000, the value of his or her
     vested Plan Benefit at all times thereafter will be deemed to exceed
     $5,000.

8.9  Distribution of Death Benefit.
     -----------------------------

     (a)  Notwithstanding any Beneficiary designation that may be to the
          contrary, if a Participant who has elected to receive a Lifetime
          Annuity (and who has not subsequently waived such Lifetime Annuity in
          accordance with Section 8.7(b)) dies before the Annuity Starting Date
          with respect to such Lifetime Annuity, and if he or she is married at
          the time of his or her death, the vested balance in his or her Account
          shall be applied toward the purchase of a Single Life Annuity for the
          Participant's surviving spouse.

     (b)  Except as provided in Subsection (a) above, if a Participant dies
          before the Annuity Starting Date (i.e., with respect to any form of
          distribution specified in Section 8.6(a)(l)-(4)), the vested balance
          in his or her Account shall be distributed to his or her Beneficiary
          in such form as such Beneficiary may elect from among the alternatives
          specified in Section 8.6(a)(l)-(3). In the absence of an election by
          the Beneficiary, payment shall be made in the form designated by the
          Participant, or, if none, in a single sum cash distribution.

     (c)  If a Participant dies after the Annuity Starting Date with respect to
          the form of distribution in effect under Section 8.6, the remaining
          amounts that had not yet been distributed under such form of
          distribution, if any, shall be paid to the Participant's Beneficiary
          in accordance with the applicable terms of such distribution method.
          In the case of a distribution in the form of an annuity contract
          (including a Lifetime Annuity) under Section 8.6(a)(4) or (5), the
          amount and timing of death or survivor benefit payments, if any, shall
          be as determined under such annuity contract.

8.10 Small Benefits: Lump Sum. Any other provision of this Article
     ------------------------
     notwithstanding, if the value of a Participant's entire Plan Benefit equals
     $5,000 or less (including a Plan Benefit of $0) before the first payment of
     the Plan Benefit is made, then the Plan Benefit shall be paid (or deemed
     paid if the Plan Benefit is $0) as soon as reasonably practicable after the
     Participant's termination of employment to the Participant (or to his or
     her Beneficiary in the case of the Participant's death) in a single lump
     sum in cash.

8.11 Direct Rollovers.  A "Distributee" who is a Participant, an Alternate
     ----------------
     Payee under a QDRO or a Beneficiary who is a deceased Participant's
     surviving spouse may elect to have a distribution of a Plan Benefit paid
     directly to the Eligible Retirement Plan (defined in Subsection (a) below)
     specified by the Distributee in a Direct Rollover, except to the extent
     that the distribution is not an Eligible Rollover Distribution (defined
     below in Subsection (b)).

     (a)  Definition of Eligible Retirement Plan. An Eligible Retirement Plan
          --------------------------------------
          is an individual retirement account described in Section 408(a) of the
          Code, an individual retirement annuity described in Section 408(b) of
          the Code, an annuity plan described in Section 403(a) of the Code, or
          a qualified trust described in Section 401(a) of the Code, that
          accepts the Distributee's Eligible Rollover Distribution. However, in
          the case of an Eligible Rollover Distribution to a Beneficiary who is
          the Participant's surviving spouse, an Eligible Retirement Plan is an
          individual retirement account or individual retirement annuity.

     (b)  Definition of Eligible Rollover Distribution.  An Eligible Rollover
          --------------------------------------------
          Distribution is any distribution of all or any portion of the balance
          to the credit of the Distributee, except that an Eligible Rollover
          Distribution does not include: (1) any distribution that is one of a
          series of substantially equal periodic payments (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 10 years or more; (2) any distribution to the
          extent the distribution is required under Section 401(a)(9) of the
          Code; and (3) the portion of any distribution that is not includable
          in gross income (determined without regard to the exclusion for net
          unrealized appreciation with respect to employer securities).

8.12 Beneficiary.  Subject to Section 8.13, a Participant's Beneficiary shall
     -----------
     be the person(s) so designated by the Participant. If the Participant has
     not made an effective designation of a Beneficiary, or if the named
     Beneficiary is not living when a distribution is to be made, then (a) the
     then-living spouse of the deceased Participant shall be the Beneficiary or
     (b) if none, the then-living children of the deceased Participant shall be
     the Beneficiaries in equal shares or (c) if none, the then-living parents
     of the deceased Participant shall be the Beneficiaries in equal shares, or
     (d) if none, the then-living brothers and/or sisters of the deceased
     Participant shall be the Beneficiaries in equal shares, or (e) if none, the
     estate of the Participant shall be the Beneficiary. The Participant may
     change his or her designation of a Beneficiary from time to time. Any
     designation of a Beneficiary (or an amendment or revocation thereof) shall
     be effective only if it is made according to the procedures prescribed by
     the Company and is received by the Participating Company prior to the
     Participant's death.

8.13 Spousal Consent Needed to Name a Nonspouse Beneficiary.  Any other
     ------------------------------------------------------
     provision of the Plan notwithstanding, in the case of a married
     Participant, any designation of a person other than his or her spouse as
     Beneficiary shall be effective only if the spouse consents in writing to
     the designation. The spouse's consent shall be witnessed by a notary public
     or, if permitted by the Company, by a representative of the Plan. A consent
     to a designation of a particular Beneficiary, once given by the spouse,
     shall not be revocable by that spouse. The designation of a particular
     Beneficiary may not be changed without further spousal consent (unless the
     consent or a prior consent expressly permits designations by the
     Participant without any requirement of further consent by the spouse).
     However, a designation of Beneficiary made by a Participant and consented
     to by the spouse may be revoked by the Participant in writing without the
     consent of the spouse at any time prior to the Annuity Starting Date. Any
     new election must comply with the requirements of this section. The
     spouse's consent shall not be required if the Participant establishes to
     the Company's satisfaction that the spouse's consent cannot be obtained
     because the spouse cannot be located or because of other reasons deemed
     acceptable under applicable regulations. The Company may require such
     evidence of the right of any person to receive payment under this Section
     as the Company may deem advisable. The Company's determination of the right
     under this Section of any person to receive payment shall be conclusive.

8.14 Determination of Marital Status.  Whether a Participant is married shall
     -------------------------------
     be determined by the Company as of the date when distribution is to be
     made.

8.15 Incapacity.  If, in the Company's opinion, a Participant or Beneficiary
     ----------
     for any reason is incompetent or becomes unable to handle properly any
     property distributable to him or her under the Plan, then the Company may
     make any arrangements that it determines to be beneficial to the
     Participant or Beneficiary for the distribution of such property on his or
     her behalf, including (without limitation) the distribution of such
     property to the guardian, conservator, spouse or dependent(s) of the
     Participant or Beneficiary.

ARTICLE 9.  DISTRIBUTION TO AN ALTERNATE PAYEE UNDER A QDRO; FREEZING
---------------------------------------------------------------------
            PARTICIPANT ACCOUNTS
            --------------------

9.1  Immediate Distribution.

     (a)  Any distribution to an Alternate Payee of all or some portion of a
          Participant's Accounts pursuant to a qualified domestic relations
          order, shall be made as soon as reasonably practicable after the order
          is determined to be a QDRO, if:

          (1)  The QDRO specifies such time of distribution; or

                                       27
<PAGE>

          (2)  The Alternate Payee has consented in writing to such time of
               distribution.

     (b)  Notwithstanding the foregoing, in determining the award to an
          Alternate Payee under a QDRO, the award to the Alternate Payee shall
          be derived solely from a portion of the Participant's vested Accounts
          in the Plan as of the Valuation Date provided in the QDRO.

9.2  Alternate Payee Accounts.  In all cases where Section 9.1 above is not
     ------------------------
     applicable, separate "Alternate Payee Accounts" shall be established for
     the Alternate Payee at such time as the Company shall determine. The
     portion of each of the Participant's Accounts that was assigned or made
     payable to the Alternate Payee by the QDRO shall be transferred to such
     Alternate Payee Accounts. Unless the QDRO otherwise provides, the transfers
     to the Alternate Payee Accounts shall be made pro rata from the
     Participant's Accounts. Alternate Payees may change the investment of their
     Alternate Payee Accounts pursuant to Section 6.9. Alternate Payees may not
     take loans or make withdrawals from their Alternate Payee Accounts under
     Articles 10 and 11. Alternate Payees may not make any contributions to
     their Alternate Payee Accounts.

9.3  Freezing Participant Accounts. As soon as practicable after the date the
     -----------------------------
     Plan Administrator receives credible information that a qualified domestic
     relations order, pursuant to Code Section 401(a)(13) and ERISA Section
     206(d)(3), may be forthcoming, the Plan Administrator shall freeze the
     relevant Participant's Accounts for a reasonable period of time to permit
     the Participant and/or Alternate Payee to obtain a domestic relations
     order. As soon as practicable after the date the Plan Administrator
     receives a domestic relations order, the Plan Administrator shall freeze
     the relevant Participant's Accounts for a period of up to 18 months to
     allow for a determination of whether the domestic relations order meets the
     requirements of a qualified domestic relations order as defined in Code
     Section 414(p) and ERISA Section 206(d)(3). To the extent that a
     Participant's Accounts are frozen, no loans, withdrawals or distributions
     are permitted from such Accounts.

9.4  Death of Alternate Payee.  In all cases, if Alternate Payee dies prior to
     ------------------------
     the time that Alternate Payee has received all or any portion of the
     benefits assigned Alternate Payee by a QDRO, the benefits shall be paid to
     the Beneficiary(ies) designated by Alternate Payee on forms provided by the
     Plan Administrator for this purpose. If Alternate Payee has not made an
     effective designation of Beneficiary or if the designated Beneficiary is
     not living when a distribution is to be made, the entire balance in his or
     her Alternate Payee Accounts shall be distributed to his or her estate
     (unless the QDRO otherwise provides).

9.5  Distributions From Alternate Payee Accounts.  Distributions to Alternate
     -------------------------------------------
     Payees from their Alternate Payee Accounts shall be made as soon as
     reasonably

                                       28
<PAGE>

     practicable after the Plan Administrator's receipt of completed
     distribution forms provided by the Plan Administrator for this purpose.

ARTICLE 10.  LOANS.
------------------

10.1  Amount of Loan.  A Participant may obtain a cash loan from his or her
      --------------
      Accounts if he or she is an Employee who is not on a leave of absence at
      the time of the loan and his or her Plan participation is not suspended
      pursuant to Section 3.5. The minimum amount of any such loan shall be
      $1,000 at the time the loan is elected. No loan shall be granted under the
      Plan if such loan, when aggregated with the Participant's outstanding
      loans under any other qualified plans maintained by any member of the
      Affiliated Group, would exceed the lesser of:

      (a) $50,000, less the amount by which such aggregate balance has been
          reduced through repayments during the period of 12 months ending on
          the day before the new loan is made; or

      (b) One-half of the Participant's vested interest in his or her Accounts.

10.2  Terms of Loans.  A loan to a Participant shall be made on such terms and
      --------------
      conditions as the Company may determine, provided that the loan shall:

      (a) Be evidenced by a promissory note signed by the Participant and
          secured by one-half of the value of his or her Accounts, to the extent
          vested (regardless of the amount of the loan or the source of the loan
          funds);

      (b) Bear interest at a fixed rate commensurate with the interest rates
          charged by major financial institutions for similar loans;

      (c) Provide for level amortization over its term with payments at monthly
          or more frequent intervals, as determined by the Company;

      (d) Provide for loan payments (1) to be withheld whenever possible through
          periodic payroll deductions from the Participant's compensation from
          any member of the Affiliated Group or (2) to be paid by check or money
          order whenever payroll withholding is not possible;

      (e) Provide for repayment in full on or before the earlier of (1) the date
          when the Participant severs from all employment with any member of the
          Affiliated Group or (2) the date (A) five years after the loan is made
          or (B) 20 years after the loan is made if the loan is used to acquire
          a dwelling unit which within a reasonable time is to be used as the
          Participant's principal residence;

                                       29
<PAGE>

      (f)  Provide that a Participant may not receive any distribution from any
           of his or her Accounts under Article 8 or 11 until the loan
           obligation is repaid, except to the extent that all or any part of
           such distribution is used to repay the outstanding balance of the
           loan; and

      (g)  Provide that a Participant's Accounts may not be applied to the
           satisfaction of the Participant's loan obligations before the
           Accounts become distributable under Article 8, unless the Company
           determines that the loan obligations are in default because a
           periodic payment is more than 60 days past due and takes such actions
           as the Company deems necessary or appropriate to cause the Plan to
           realize on its security for the loan. Such actions may include
           (without limitation) an involuntary withdrawal from the Participant's
           Accounts, whether or not the withdrawal would be permitted under
           Article 11 on a voluntary basis; provided that an involuntary
           withdrawal attributable to Company Contributions made with respect to
           Plan Years that ended less than 24 months prior to the date of the
           withdrawal (adjusted to reflect any earnings, appreciation or losses
           attributable to Company Contributions) or attributable to Participant
           Elected Contributions shall be permitted only to the extent that the
           hardship requirements of Code Section 401(k)(2)(B)(I)(IV) and of
           Sections 1.401(k)-l(d)(2)(ii) and 1.401(k)1(d)(2)(iii)(A) of the
           Treasury Regulations are met. The Company may take such other action
           as it deems necessary to recover the balance of a loan secured by the
           Participant's Accounts. If an involuntary withdrawal occurs (or would
           have occurred if permitted under this Section, the Participant shall
           not be permitted to obtain a loan under the Plan thereafter.

10.3  Company Consent.  The Company, in its sole discretion, may withhold its
      ---------------
      consent to any loan under this Article or may consent only to the
      borrowing of a part of the amount requested by the Participant. The
      Company shall act upon requests for loans in a uniform and
      nondiscriminatory manner, consistent with the requirements of Section
      401(a), Section 401(k) and related provisions of the Code.

10.4  Source of Loans.   If a Participant requests and is granted a loan, a Loan
      ---------------
      Account shall be established for the Participant. The Loan Account shall
      be held by the Trustee as part of the Loan Fund. The amount of the loan
      shall be transferred to the Participant's Loan Account from the
      Participant's other Accounts and shall be disbursed from the Loan Account.
      Transfers from the Company Stock Fund shall be made in accordance with the
      requirements for exemption under Section 16(b) of the Exchange Act if such
      a transfer would cause the Participant to incur short-swing trading
      profits liability under Section 16(b) of the Exchange Act. The promissory
      note executed by the Participant shall be held by the Trustee (or by the

                                       30
<PAGE>

      Company as agent of the Trustee) and the promissory note shall be treated
      as an investment of the Participant's Loan Account.

10.5  Disbursement of Loans.   A Participant may request a loan by completing
      ---------------------
      the loan request procedures prescribed by the Company. A loan shall be
      disbursed as soon as reasonably practicable after the date on which the
      Company (or its agent) receives the loan request (subject to the Company's
      consent).

10.6  Loan Fees.   A Participant who obtains a loan under this Article shall be
      ---------
      required to pay such fees as the Company may impose in order to defray the
      cost of administering loans from the Plan.

10.7  Valuation Date.  For purposes of this Article, the value of a
      --------------
      Participant's Accounts shall be determined as of a Valuation Date within a
      reasonable period, not generally to exceed 30 days, on or after the date
      on which the Company (or its agent) receives the prescribed loan request.

10.8  Loan Payments and Defaults.  Principal and interest payments on a
      --------------------------
      Participant's loan shall be credited initially to the Participant's Loan
      Account and shall be transferred as soon as reasonably practicable
      thereafter to the Participant's other Accounts in the ratio specified by
      the Participant under Section 6.2 for the investment of future
      contributions. Any loss caused by nonpayment or other default on a
      Participant's loan obligations shall be satisfied solely by that
      Participant's Accounts. If a Participant defaults on a Plan loan, both his
      or her participation and ability to obtain a Plan loan shall be suspended
      for 12 months. The consequences of suspension from participation in the
      Plan are described in Section 3.5.

11.3  Amount of a Hardship Withdrawal.  The maximum amount of a Hardship
      -------------------------------
      Withdrawal is the amount necessary to satisfy the immediate and heavy
      financial need caused by the Hardship, including amounts necessary to pay
      taxes or penalties that the Company determines may be reasonably
      anticipated to result from the Hardship Withdrawal. The determination of
      the amount of a permitted Hardship Withdrawal is made by the Company only
      after the Participant has obtained all withdrawals and distributions,

          members of the Affiliated Group shall be limited to the Annual
          Deferral Limit, as defined in Section 13.9(b), minus the amount of the

      from the Company Stock Fund shall be limited when necessary to avoid
      liability from the short-swing trading profits provisions of Section 16(b)
      of the Exchange Act.

      as an active Employee for either the separation year or any determination
      year ending on or after the Employee's 55th birthday. The determination of

          (1)  Any Employee covered by a collective bargaining agreement;

          (2)  Any Employee who is a nonresident alien with respect to the

          (6)  Any Employee who has not attained the age of 21 at the end of the
               Plan Year.

      The Company may elect, in a consistent and uniform manner, to apply one or

      younger

                                       34

      Participant for any calendar year, together with any other elective
      deferrals (within the meaning of Section 402(g)(3) of the Code) under all
      plans, contracts or arrangements of the Affiliated Group and any other
      employers, exceed the Annual Deferral Limit, then the Participant may
      designate all or a portion of such Excess Deferrals as attributable to
      this Plan and may request a refund of such portion by notifying the
      Company in writing on or before the March 1 next following the close of
      such calendar year. If timely notice is received by the Company, then such
      portion of the Excess Deferrals, and any income or loss allocable to such
      portion, shall be refunded to the Participant not later than the April 15
      next following the close of such calendar year.

      If the Participant fails properly to request a distribution of all such
      Excess Deferrals, and such Excess Deferrals are attributable solely to
      plans, contracts or arrangements of the Affiliated Group, then the Company
      shall be deemed to have notice of such Excess Deferrals and shall
      designate one or more plans maintained by a member of the Affiliated Group
      from which the refund of Excess Deferrals and allocable income or loss
      shall be made no later than April 15 next following the close of such
      calendar year.

      Any Participant Elected Contributions distributed pursuant to this Section
      13.1 shall not be included in the Participant Elected Contributions to
      which a Matching Contribution under Section 5.1 or a Qualified Matching
      Contribution under Section 5.4 of the Plan attaches.

                                       35

13.2  Actual Deferral Percentage Limitation. The Plan shall satisfy the actual
      -------------------------------------
      deferral percentage test, as provided in Section 401(k)(3) of the Code and
      the regulations issued thereunder. Subject to the special rules described
      in Section 13.7, the Aggregate 401(k) Contributions of Highly Compensated
      Employees shall not exceed the limits described below:

      (a) An Actual Deferral Percentage shall be determined for each individual
          who, at any time during the Plan Year, is a Participant (including a
          suspended Participant) or is eligible to participate in the Plan,
          which Actual Deferral Percentage shall be the ratio, computed to the
          nearest one-hundredth of one percent, of the individual's Aggregate
          401(k) Contributions for the Plan Year to the individual's Section
          414(s) Compensation for the Plan Year;

      (b) The Actual Deferral Percentages (including zero percentages) of Highly
          Compensated Employees and Nonhighly Compensated Employees shall be
          separately averaged to determine each group's Average Deferral
          Percentage; and

      (c) The Aggregate 401(k) Contributions of Highly Compensated Employees
          shall constitute Excess Contributions and shall be reduced, pursuant
          to Sections 13.3 and 13.4, to the extent that the Average Deferral
          Percentage of Highly Compensated Employees exceeds the greater of (1)
          125 percent of the Average Deferral Percentage of Nonhighly
          Compensated Employees for the preceding Plan Year or (2) the lesser of
          (A) 200 percent of the Average Deferral Percentage of Nonhighly
          Compensated Employees for the preceding Plan Year or (B) the Average
          Deferral Percentage of Nonhighly Compensated Employees for the
          preceding Plan Year plus two percentage points.

13.3  Allocation of Excess Contributions to Highly Compensated Employees. Any
      ------------------------------------------------------------------
      Excess Contributions for a Plan Year shall be allocated to Highly
      Compensated Employees by use of a leveling process, whereby the amount of
      Aggregate 401(k) Contributions of the Highly Compensated Employee with the
      highest amount of Aggregate 401(k) Contributions is reduced to the extent
      required to (a) eliminate all Excess Contributions or (b) cause such
      Highly Compensated Employee's amount of Aggregate 401(k) Contributions to
      equal the amount of Aggregate 401(k) Contributions of the Highly
      Compensated Employee with the next highest amount of Aggregate 401(k)
      Contributions. The leveling process shall be repeated until all Excess
      Contributions for the Plan Year are allocated to Highly Compensated
      Employees.

13.4  Distribution of Excess Contributions.  Excess Contributions allocated to
      ------------------------------------
      Highly Compensated Employees for the Plan Year pursuant to Section 13.3,
      together with any income or loss allocable to such Excess Contributions,
      shall be

                                       36
<PAGE>

      distributed to such Highly Compensated Employees not later than two-and-
      one-half months following the close of such Plan Year, if possible, and in
      any event no later than 12 months following the close of such Plan Year.
      Any Participant Elected Contributions distributed pursuant to this Section
      13.4 shall not be included in the Participant Elected Contributions to
      which a Matching Contribution under Section 5.1 or a Qualified Matching
      Contribution under Section 5.4 of the Plan attaches.

13.5  Qualified Matching Contributions.  The Company, in its sole discretion,
      --------------------------------
      may include all or a portion of the Qualified Matching Contributions for a
      Plan Year in Aggregate 401(k) Contributions taken into account in applying
      the Average Deferral Percentage limitation described in Section 13.2 for
      the Plan Year; provided that such Qualified Matching Contributions for the
      Plan Year are fully and immediately vested, may not be withdrawn while the
      Participant is an Employee or may be withdrawn only in circumstances that
      would permit a Hardship Withdrawal, and the additional requirements of
      Treasury Regulation Section 1.401(k)-l(b)(5) are satisfied.

13.6  Corrective Qualified Nonelective Contributions.  In order to satisfy (or
      ----------------------------------------------
      partially satisfy) the Average Deferral Percentage limitation described in
      Section 13.2, the Average Contribution Percentage limitation described in
      Section 14.1 or the multiple-use limitation described in Section 15.1 (or
      more than one of such limitations), the Company, in its sole discretion,
      may cause one or more Participating Companies to make a Qualified
      Nonelective Contribution to the Plan. Any such Qualified Nonelective
      Contribution shall be allocated to the Accounts of those Participants who
      are eligible to receive an allocation of Matching Contributions under
      Section 5.1 of the Plan or Nonelective Contributions under Section 5.2, as
      the Company designates, and who are Nonhighly Compensated Employees for
      the Plan Year with respect to which the Qualified Nonelective Contribution
      is made, beginning with the Participant with the lowest Section 414(s)
      Compensation for the Plan Year and allocating the maximum amount
      permissible under Article 16 before allocating any portion of the
      Qualified Nonelective Contribution to the Participant with the next lowest
      Section 414(s) Compensation. These allocations shall continue until the
      Plan satisfies the Average Deferral Percentage limitation described in
      Section 13.2, the Average Contribution Percentage limitation described in
      Section 14.1 or the multiple-use limitation described in Section 15.1 (or
      more than one of such limitations), or until the amount of the Qualified
      Nonelective Contribution is exhausted.

      The Company, in its sole discretion, may include all or a portion of the
      Qualified Nonelective Contributions for a Plan Year in Aggregate 401(k)
      Contributions taken into account in applying the Average Deferral
      Percentage limitation

                                       37
<PAGE>

      described in Section 13.2 for such Plan Year, provided that the
      requirements of Treasury Regulation Section 1.401(k)l(b)(5) are satisfied.

      Qualified Nonelective Contributions shall be paid to the Trustee as soon
      as reasonably practicable following the close of the Plan Year, shall be
      allocated to the Accounts of Nonhighly Compensated Employees as of the
      last day of the Plan Year and shall be fully and immediately vested. In
      all other respects, the contribution, allocation, investment and
      distribution of Qualified Nonelective Contributions shall be governed by
      the provisions of the Plan concerning Matching Contributions.

13.7  Special Rules.  The following special rules shall apply for purposes of
      -------------
      this Article 13:

      (a) The amount of Excess Deferrals to be distributed to a Participant for
          a calendar year pursuant to Section 13.1 shall be reduced by the
          amount of any Excess Contributions previously distributed to such
          Participant for the Plan Year beginning within such calendar year;

      (b) The amount of Excess Contributions to be distributed to a Participant
          for a Plan Year pursuant to Section 13.4 shall be reduced by the
          amount of any Excess Deferrals previously distributed to such
          Participant for the calendar year ending within such Plan Year;

      (c) For purposes of applying the limitation described in Section 13.2, the
          Actual Deferral Percentage of any Highly Compensated Employee who is
          eligible to make Participant Elected Contributions and to make
          elective deferrals (within the meaning of Section 402(g)(3) of the
          Code) under any other plans, contracts or arrangements of the
          Affiliated Group shall be determined as if all such Participant
          Elected Contributions and elective deferrals were made under a single
          arrangement; provided, however, that plans, contracts and arrangements
          shall not be treated as a single arrangement to the extent that
          Treasury Regulation Section 1.401(k)-l(b)(3)(ii)(B) prohibits
          aggregation;

      (d) In the event that this Plan is aggregated with one or more other plans
          in order to satisfy the requirements of Code Section 401(a)(4), 401(k)
          or 410(b), then all such aggregated plans, including the Plan, shall
          be treated as a single plan for all purposes under all such Code
          sections (except for purposes of the average benefit percentage
          provisions of Code Section 410(b)(2)(A)(ii));

      (e) In the event that the mandatory disaggregation rules of Treasury
          Regulation Section 1.401(k)-l(b)(3)(ii)(B) apply to the Plan, or to
          the Plan and other plans with which it is aggregated as described in
          Subsection (d)

                                       38
<PAGE>

          above, then the limitation described in Section 13.2 shall be applied
          as if each mandatorily disaggregated portion of the Plan (or
          aggregated plans) were a single arrangement; and

      (f) Income (and loss) allocable to Excess Contributions for the Plan Year
          shall be determined pursuant to the provisions for allocating income
          (and loss) to a Participant's Accounts under Section 6.10 of the Plan.

13.8  Prospective Limitations on Participant Elected Contributions.  At any
      ------------------------------------------------------------
      time, the Company (at its sole discretion) may reduce the maximum rate at
      which any Participant may make Participant Elected Contributions to the
      Plan, or the Company may require that any Participant discontinue all
      Participant Elected Contributions, in order to ensure that the limitations
      described in this Article 13 are met. Any reduction or discontinuance of
      Participant Elected Contributions may be applied selectively to individual
      Participants or to particular classes of Participants, as the Company may
      determine. Upon such date as the Company may determine, this Section shall
      automatically cease to apply until the Company again determines that a
      reduction or discontinuance of Participant Elected Contributions is
      required for any Participant.

13.9  Special Definitions Used in Article 13.  The following definitions shall
      --------------------------------------
      apply for purposes of this Article 13, and some may also apply for one or
      more of Articles 14, 15 and 16.

      (a) "Aggregate 401(k) Contributions"  means, for any Plan Year, the sum

          Contributions allocated to the Participant's Accounts as of a date
          within the Plan Year, but only to the extent that such Qualified
          Matching Contributions are aggregated with Participant Elected
          Contributions pursuant to Section 13.5; and (c) the Qualified
          Nonelective Contributions allocated to the Participant's Accounts as
          of a date within the Plan Year, but only to the extent that such
          Qualified Nonelective Contributions are aggregated with Participant
          Elected Contributions pursuant to Section 13.6.

      (b) "Annual Deferral Limit" means the dollar limit in effect for any
           ---------------------
          calendar year under Section 402(g) of the Code.

      (c) "Excess Contributions" means the amount by which the Aggregate 401(k)
           --------------------
          Contributions of Highly Compensated Employees is reduced pursuant to

<PAGE>

          Section 402(g)(3) of the Code) that exceed the Annual Deferral Limit
          set forth in Section 13.1 (as defined in Section 13.9).

      (e) "Section 414(s) Compensation" means any one of the following

          the Affiliated Group:

          (1)  Compensation as defined in Treasury Regulation Section 1.415-2(d)
               or any successor thereto;

          (2)  "Wages" as defined in Section 3401(a) of the Code for purposes of
               income tax withholding at the source, but determined without
               regard to any rules that limit the remuneration included in wages
               based on the nature or location of the employment or the services
               performed (such as the exception for agricultural labor in
               Section 3401(a)(23) of the Code);

               6051(a)(3) and the regulations thereunder, determined without
               regard to any rules that limit such Wages or reportable
               compensation based on the nature or location of the employment or
               the services performed (such as the exception for agricultural
               labor in Section 3401(a)(23) of the Code), and modified, at the
               election of the Company, to exclude amounts paid or reimbursed
               for the Employee's moving expenses, to the extent it is
               reasonable to believe that these amounts are deductible by the
               Employee under Section 217 of the Code;

          (4)  Any of the definitions of Section 414(s) Compensation set forth
               in Subsections (1), (2) and (3) above, reduced by all of the
               following items (even if includable in gross income):
               reimbursements or other expense allowances, fringe benefits (cash
               and noncash), moving expenses, deferred compensation and welfare
               benefits;

               the following: (a) any elective contributions made by a member of
               the Affiliated Group on behalf of the Employee that are not
               includable in gross income under Section 125, 402(e)(3), 402(h)
               or 403(b) of the Code; (b) compensation deferred under an

               457(b) of the Code; and (c) employee contributions described in

                                       40
<PAGE>

               Section 414(h)(2) of the Code that are picked up by the employing
               unit and thus are treated as employer contributions; or

          (6)  Any reasonable definition of compensation that does not by design
               favor Highly Compensated Employees and that satisfies the
               nondiscrimination requirement set forth in Treasury Regulation
               Section 1.414(s)-lT(d)(2) or the successor thereto.

          Any definition of Section 414(s) Compensation shall be used
          consistently to define the compensation of all Employees taken into
          account in satisfying the requirements of an applicable provision of
          Articles 13, 14, 15 and 16 for the relevant determination period.  For
          purposes of applying the limitations set forth in Articles 13, 14 and
          15 for a Plan Year, Section 414(s) Compensation shall not exceed the
          Compensation Limitation.

ARTICLE 14.  CONTRIBUTION LIMITATIONS: AVERAGE CONTRIBUTION PERCENTAGE
----------------------------------------------------------------------
              LIMITATIONS.
              -----------

14.1  Average Contribution Percentage Limitation.  The Plan shall satisfy the
      ------------------------------------------
      actual contribution percentage test, as provided in Section 401(m)(2) of
      the Code and Section 1.401(m)-l of the regulations issued thereunder.
      Subject to the special rules described in Section 14.6, the Aggregate
      401(m) Contributions of Highly Compensated Employees shall not exceed the
      limits described below:

      (a) An Actual Contribution Percentage shall be determined for each
          individual who, at any time during the Plan Year, is a Participant
          (including a suspended Participant) or is eligible to participate in
          the Plan, which Actual Contribution Percentage shall be the ratio,
          computed to the nearest one-hundredth of one percent, of the
          individual's Aggregate 401(m) Contributions for the Plan Year to the
          individual's Section 414(s) Compensation for the Plan Year;

      (b) The Actual Contribution Percentages (including zero percentages) of
          Highly Compensated Employees and Nonhighly Compensated Employees shall
          be separately averaged to determine each group's Average Contribution
          Percentage; and

      (c) The Aggregate 401(m) Contributions of Highly Compensated Employees
          shall constitute Excess Aggregate Contributions and shall be reduced,
          pursuant to Sections 14.2 and 14.3, to the extent that the Average
          Contribution Percentage of Highly Compensated Employees exceeds the
          greater of (1) 125 percent of the Average Contribution Percentage of
          Nonhighly Compensated Employees for the preceding Plan Year or (2) the
          lesser of (A) 200 percent of the Average Contribution Percentage of

                                       41
<PAGE>

          Nonhighly Compensated Employees for the preceding Plan Year or (B) the
          Average Contribution Percentage of Nonhighly Compensated Employees for
          the preceding Plan Year plus two percentage points.

14.2  Allocation of Excess Aggregate Contributions to Highly Compensated
      ------------------------------------------------------------------
      Employees.  Any Excess Aggregate Contributions for a Plan Year shall be
      ---------
      allocated to Highly Compensated Employees by use of a leveling process,
      whereby the Aggregate 401(m) Contributions of the Highly Compensated
      Employee with the highest amount of Aggregate 401(m) Contributions is
      reduced to the extent required to (a) eliminate all Excess Aggregate
      Contributions or (b) cause the amount of such Highly Compensated
      Employee's Aggregate 401(m) Contributions to equal the amount of Aggregate
      401(m) Contributions of the Highly Compensated Employee with the next-
      highest amount of Aggregate 401(m) Contributions. The leveling process
      shall be repeated until all Excess Aggregate Contributions for the Plan
      Year are allocated to Highly Compensated Employees.

14.3  Distribution of Excess Aggregate Contributions.  Excess Aggregate
      ----------------------------------------------
      Contributions allocated to Highly Compensated Employees for the Plan Year
      pursuant to Section 14.2, together with any income or loss allocable to
      such Excess Aggregate Contributions, shall be distributed to such Highly
      Compensated Employees not later than two-and-one-half months following the
      close of such Plan Year, if possible, and in any event no later than 12
      months following the close of such Plan Year, but only to the extent the
      Highly Compensated Employee has a nonforfeitable interest in the Excess
      Aggregate contributions. Excess Aggregate Contributions (for Participants
      who are Highly Compensated Employees), to the extent not vested, may be
      forfeited and allocated, after all other Forfeitures under the Plan, to
      other Participants (but in no event to any Highly Compensated Employee) in
      the proportion that such Participant's Participant Elected Contributions,
      if any, for that Plan Year bears to the total Participant Elected
      Contributions of all such Participants for the Plan Year. Any such amounts
      shall be included in the calculation of the Actual Contribution Percentage
      and in the calculation of the limits set forth in Article 16.

14.4  Use of Participant Elected Contributions.  The Company, in its sole
      ----------------------------------------
      discretion, may include all or a portion of the Participant Elected
      Contributions for a Plan Year in Aggregate 401(m) Contributions taken into
      account in applying the Average Contribution Percentage limitation
      described in Section 14.1 for the Plan Year, provided that all Participant
      Elected Contributions satisfy the average deferral percentage test, as
      described in Section 13.2, and that the additional requirements of
      Treasury Regulation Section 1.401(m)-l(b)(5) are satisfied.

14.5  Corrective Qualified Nonelective Contributions.  The Company, in its sole
      ----------------------------------------------
      discretion, may include all or a portion of the Qualified Nonelective
      Contributions

                                       42
<PAGE>

      made pursuant to Section 13.6 for a Plan Year in Aggregate 401(m)
      Contributions taken into account in applying the Average Contribution
      Percentage limitation described in Section 14.1 for the Plan Year,
      provided that the requirements of Treasury Regulation Section 1.401(m)-
      l(b)(5) are satisfied.

14.6  Special Rules.  The following special rules shall apply for purposes of
      -------------
      this Article 14:

      (a) For purposes of applying the limitation described in Section 14.1, the
          Actual Contribution Percentage of any Highly Compensated Employee who
          is eligible to participate in the Plan and to make employee
          contributions or receive an allocation of matching contributions
          (within the meaning of Section 401(m)(4)(A) of the Code) under any
          other plans, contracts or arrangements of the Affiliated Group shall
          be determined as if Matching Contributions and Qualified Matching
          Contributions allocated to the Highly Compensated Employee's Accounts
          and all such employee contributions and matching contributions were
          made under a single arrangement;

      (b) In the event that this Plan is aggregated with one or more other plans
          in order to satisfy the requirements of Code Section 401(a)(4), 401(m)
          or 410(b), then all such aggregated plans, including the Plan, shall
          be treated as a single plan for all purposes under all such Code
          sections (except for purposes of the average benefit percentage
          provisions of Code Section 410(b)(2)(A)(ii));

      (c) In the event that the mandatory disaggregation rules of Treasury

ARTICLE 16.  CONTRIBUTION LIMITATIONS:  SECTION 415 "ANNUAL ADDITIONS"
----------------------------------------------------------------------
             LIMITATIONS.
             -----------

16.1  Limitation on Contributions.  The Annual Additions allocated or attributed
      ---------------------------

      following:

      (a) $30,000; or

      (b) 25% of the Participant's Section 415 Compensation for such year.

      If a Participant's Annual Additions would exceed the foregoing limitation,
      then such Annual Additions shall be reduced by reducing the components
      thereof as necessary in the order in which they are listed in Section
      16.5(a). Any amounts so reduced shall not be included in a Participant's
      Aggregate 401(k) Contributions or Aggregate 401(m) Contributions. The
      limitation in Section 16.1(b) shall not apply to any amount that otherwise
      is an Annual Addition under Section 415(l)(1) or 419A(d)(2) of the Code.

                                       45

16.2  Combined Limitation on Benefits and Contributions.  The sum of a
      -------------------------------------------------
      Participant's defined-benefit plan fraction and his or her defined
      contribution plan fraction shall not exceed 1.0 with respect to any Plan
      Year. For purposes of this Section, the terms "defined-benefit plan
      fraction" and "defined-contribution plan fraction" shall have the meaning
      given to such terms by Section 415(e) of the Code and the regulations
      thereunder. If a Participant would exceed the foregoing limitation, then
      the Participant's benefits under any qualified defined-benefit plan that
      may be maintained by the Section 415 Employer Group shall be reduced as
      necessary to allow his or her Annual Additions to equal the maximum
      permitted by Section 16.l.

16.3  Return of Employee Contributions.  If the amount of any Participant's
      --------------------------------
      Participant Elected Contributions is determined to be an excess Annual
      Addition under this Article, then the amount of such excess (adjusted to
      reflect any earnings, appreciation or losses attributable to such excess)
      shall be refunded by the Trustee in cash to the Participant.

16.4  Excess Company Contributions.  If the amount of the Company Contributions
      ----------------------------
      allocated to a Participant for any Plan Year must be reduced to meet the
      limitation described in Section 16.1, then the amount of the reduction
      shall be applied to reduce the total amount that the Participating
      Companies otherwise would contribute for such year pursuant to Article 5
      of the Plan. If the amount that the Participating Companies may contribute
      is thereby reduced to zero and if there are Company Contributions that
      still cannot be allocated to any Participant because of the limitation
      described in Section 16.1, then the excess shall be transferred to a
      suspense account. Any gains, income or losses attributable to the suspense
      account shall be allocated to such account. All amounts credited to the
      suspense account shall be applied to reduce the total amount that the
      Participating Companies otherwise would contribute to the Plan for the
      next Plan Year, and for succeeding Plan Years if necessary. Such amounts
      shall be allocated among Participants pursuant to Article 5 of the Plan
      until the suspense account is exhausted (subject to this Article). No
      Participant Elected Contributions or Company Contributions shall be made
      as long as any amount remains in the suspense account.

               Participant contributes during such year;

          415 Employer Group. Any definition of Section 415 Compensation shall
          be used consistently to define the compensation of all Employees taken
          into account in satisfying the requirements of an applicable provision
          of the Plan for the relevant determination period.

      (c) "Section 415 Employer Group" means the Affiliated Group, except that

      --------------------
      procedures, consistent with ERISA and the Plan, as it deems necessary or

ARTICLE 20.  AMENDMENT AND TERMINATION.
--------------------------------------

20.1  Right To Amend or Terminate.  The Company expects to continue the Plan
      ---------------------------
      indefinitely. However, future conditions cannot be foreseen, and the
      Company reserves the right at any time and for any reason, by action of
      its board of directors or by a person or persons acting pursuant to a
      valid delegation of authority, (a) to amend the Plan, (b) to reduce or
      discontinue Employee Contributions, Company Contributions or all
      Contributions or (c) to terminate the Plan and the Trust Fund.

20.2  Protection of Participants.  No amendment of the Plan shall reduce the

      benefit of any Participant that accrued under the Plan prior to the date
      when such amendment is adopted, except to the extent that a reduction in
      accrued benefits may be permitted by the Code and ERISA. No Plan amendment
      or other action by the Company shall divert any part of the Plan's assets

      Participants and Beneficiaries and of defraying the reasonable expenses of
      termination. If the Plan is terminated or partially terminated, or if all
      contributions to the Plan are completely discontinued, then each
      Participant who then is an Employee and who is directly affected by such
      event shall have a 100 percent vested interest in each of his or her
      Accounts, without regard to the number of Years of Service he or she has
      completed.

20.4  Allocation of Trust Fund Upon Termination.  Upon termination of the Plan,
      -----------------------------------------
      the Trust Fund shall continue in existence until the Accounts of each
      Participant have been distributed to such Participant (or to his or her
      Beneficiary) pursuant to Article 8; provided, however, that the assets of
      the Plan shall be allocated in accordance with any applicable requirements
      under Section 403(d)(1) of ERISA.

20.5  Partial Termination.  Upon a partial termination of the Plan, Sections
      -------------------
      20.3 and 20.4 shall apply with respect to such Participants and
      Beneficiaries as are affected by such partial termination.

      receive a benefit immediately after such merger, consolidation or transfer
      (if the Plan then terminated) that is equal to or greater than the benefit
      that such Participant would have been entitled to receive immediately
      before the merger, consolidation or transfer (if the Plan had then
      terminated).

21.2  No Assignment of Property Rights.  Except as otherwise provided in Article
      --------------------------------
      9 with respect to QDROs or as provided in the following sentence, the
      interest or property rights of any Participant or Beneficiary in the Plan,
      in the Trust Fund or in any distribution to be made under the Plan shall
      not be subject to option nor be assignable, either by voluntary or
      involuntary assignment or by operation of law, including (without
      limitation) bankruptcy, garnishment, attachment or other creditor's
      process, and any act in violation of this Section 21.2 shall be void.
      Notwithstanding any Plan provision to the contrary, a Participant's Plan
      benefits shall be reduced by any amount such Participant is ordered or
      required to pay to the Plan if the order or requirement to pay arises (i)
      under a judgement or conviction for a crime involving the Plan (ii) under
      a civil judgment (including a consent order or decree) entered by a court
      in an action brought in connection with a breach (or alleged breach) of
      fiduciary duty under ERISA, or (iii) pursuant to a settlement agreement
      entered into by the Participant and the Secretary of Labor in connection
      with a breach of fiduciary duty under ERISA by a fiduciary or any other
      person; provided, however, that the judgment, order, decree, or settlement
      agreement expressly provides for the offset of all or part of the amount
      ordered or required to be paid to the Plan against the Participant's
      benefits under the Plan.

21.3  No Employment Rights.  Nothing in the Plan shall be deemed to give any
      --------------------
      individual a right to remain in the employ of an Affiliate or affect the
      right of an Affiliate to terminate an individual's employment at will with
      or without cause, at any time with or without notice, for any reason or no
      reason, which right is hereby reserved.

21.4  Choice of Law.  The Plan and all rights thereunder shall be interpreted
      -------------
      and construed in accordance with ERISA and, to the extent that state law
      is not preempted by ERISA, the law of the State of California.

21.5  Voting of Company Stock.  Before each annual or special meeting of the
      -----------------------
      Company's shareholders, the Company shall cause to be sent to each
      Participant who has invested any part of his or her Account in the Company
      Stock fund the proxy statement and any related materials that are sent to
      the Company's registered shareholders. Each Participant shall have the
      right to instruct the Trustee confidentially (in writing on the prescribed
      form) with respect to the

                                       52
<PAGE>

      voting at such meeting of the number of shares of Company Stock that were
      allocated to the Participant's Account as of the Valuation Date
      immediately preceding the record date for such meeting or such later date,
      up to and including the record date for such meeting, as the Plan
      Administrator may deem practicable. Such instructions shall be submitted
      to the Trustee by the date specified by the Company and, once received by
      the Trustee, shall be irrevocable. Under no circumstances shall the
      Trustee permit any Participating Company or any officer, employee or
      representative thereof to see any voting instructions given by a
      Participant to the Trustee. The Trustee shall vote any Company Stock for
      which it has not received timely written instructions in the same
      proportion as the Trustee votes the shares for which timely voting
      instructions have been received from Participants.

21.6  Tender Offers.  In the event that any person or group makes an offer
      -------------
      subject to Section 14(d) of the Exchange Act to acquire all or part of the
      outstanding Company Stock, including Company Stock held in the Plan
      ("Acquisition Offer"), each Participant shall be entitled to direct the
      Trustee confidentially (on a form prescribed by the Company) to tender all
      or part of those shares of Company Stock that would then be subject to
      such Participant's voting instructions under Subsection 21.5 above. If the
      Trustee receives such an instruction by a date determined by the Trustee
      and communicated to Participants, the Trustee shall tender such Company
      Stock in accordance with such instruction. Any Company Stock as to which
      the Trustee does not receive instructions within such period shall not be
      tendered by the Trustee. The Trustee shall obtain and distribute to each
      Participant all appropriate materials pertaining to the Acquisition Offer,
      including the statement of the position of the Company with respect to
      such offer issued pursuant to Regulation 14(e)-2 of the Exchange Act, as
      soon as practicable after such materials are issued, provided, however,
      that if the Company fails to issue such statement within five (5) business
      days after the commencement of such offer, the Trustee shall distribute
      such materials to each Participant without such statement by the Company
      and shall separately distribute such statement by the Company as soon as
      practicable after it is issued. The Trustee shall follow the procedures
      regarding confidentiality and verification of compliance with voting
      instructions described in Section 21.5 above.

           ---------------
          416(g) of the Code.

          5 or more                                    100%

          Participant with one or more Hours of Service in a Plan Year in which
          the Plan is a Top-Heavy Plan shall be determined under Section 7.2.

      (b) If the Plan ceases to be a Top-Heavy Plan, the vesting rules described
          in Section 7.3 shall again apply to all Years of Service with respect

          described in Subsection (a) who has at least three (3) Years of
          Service to his or her credit at the time the Plan ceases to be a Top-

              AS AMENDED AND RESTATED EFFECTIVE OCTOBER 23, 2000

     The Amgen Retirement and Savings Plan as Amended and Restated Effective

     will conform to the terms of the Plan. Thereafter, Kinetix Pharmaceuticals,
     Inc. shall no longer be a Participating Company and Appendix A to the Plan
     is thereby amended to delete Kinetix Pharmaceuticals, Inc.

  3. Effective June 1, 2001, annuities will be eliminated as a form of

     which notice will be provided to Plan participants of the elimination. As
     such:

        a.  Section 2.41 is deleted in its entirety.

        b.  Section 2.47 is deleted in its entirety.

        c.  Section 8.3 (a) restated in its entirety to read:

               Except as provided in Sections 8.5, 8.8 and 8.10, and unless a
               Participant elects otherwise, the distribution of a Participant's
               Plan Benefit under Section 8.6 shall occur or commence not later
               than sixty (60) days after the close of the Plan Year in which
               occurs the later of (i) the Participant's attainment of Normal
               Retirement Age or (ii) the Participant's termination of
               employment.  If distribution of a Participant's Plan Benefit has
               not yet occurred, on or about nine (9) months before the
               Participant's Normal Retirement Date, the Company shall furnish
               the Participant with a written explanation of the terms,
               conditions and forms of distributions available from the Plan
               with a description of the procedures for electing a form of

<PAGE>

        f.  Section 8.7 is deleted in its entirety.

        g.  Section 8.8 is restated in its entirety to read:

               Time of Distribution of Death Benefit.  If a Participant dies
               -------------------------------------
               before receiving his or her Plan Benefit, then the Participant's
               Beneficiary shall be entitled to receive the Plan Benefit
               pursuant to this Section 8.8.  (Section 8.12 provides that the
               surviving spouse of a married Participant shall be his or her
               Beneficiary, unless the Participant, with the spouse's consent,
               has otherwise elected prior to his or her death.)  The
               Participant's Plan Benefit shall be distributed to the
               Participant's Beneficiary no later than 12 months after the
               Participant's death.

        h.  Section 8.9 is deleted in its entirety.

        i.  Section 8.13 is restated in its entirety to read:

               Spousal Consent Needed to Name a Nonspouse Beneficiary.  Any
               ------------------------------------------------------
               other provision of the Plan notwithstanding, in the case of a
               married Participant, any designation of a person other than his
               or her spouse as Beneficiary shall be effective only if the
               spouse consents in writing to the designation.  The spouse's
               consent shall be witnessed by a notary public or, if permitted by
               the Company, by a representative of the Plan.  A consent to a
               designation of a particular Beneficiary, once given by the
               spouse, shall not be revocable by that spouse.  The designation
               of a particular Beneficiary may not be changed without further
               spousal consent (unless the consent or a prior consent expressly
               permits designations by the Participant without any requirement
               of further consent by the spouse).  The spouse's consent shall
               not be required if the Participant establishes to the Company's
               satisfaction that the spouse's consent cannot be obtained because
               the spouse cannot be located or because of other reasons deemed
               acceptable under applicable regulations.  The Company may require
               such evidence of the right of any person to receive payment under
               this Section as the Company may deem advisable.  The Company's
               determination of the right under this Section of any person to
               receive payment shall be conclusive.

To record this First Amendment to the Plan as set forth herein, the Company has
caused its authorized officer to execute this document this 26th day of
February, 2001.
