         work on the scheduled expiration date of such Leave. In no event shall
         an Employee's Severance be deemed to have occurred before the last day
         on which such Employee performs any services for the Sponsor or
         Affiliated Company in the capacity of an Employee with respect to which
         he or she is compensated or entitled to compensation by the Sponsor or
         Affiliated Company.

              (c) Notwithstanding the foregoing, in the case of a Participant
         who is absent by reason of a Maternity or Paternity Leave, the
         provisions of Section 2.34(c)-(d) shall apply for purposes of
         determining whether such a Participant has incurred a Break in Service
         by reason of such Leave.

         2.47 Severance Date. "Severance Date" shall mean, in the case of any
Employee who incurs a Severance, the day on which such Employee is deemed to
have incurred said Severance as determined in accordance with the provisions of
Section 2.46, provided, however, that the special rules set forth under Section
2.34(c)-(d) shall apply with respect to determining whether a Participant on a
Maternity or Paternity Leave has incurred a Break in Service. In the case of any
Employee who incurs a Severance as provided under Section 2.46 and who is
entitled to a subsequent payment of compensation for reasons other than future
services (e.g., as back pay for past services rendered or as payments in the
nature of severance pay), the Severance Date of such Employee shall be as of the
effective date of the Severance event (e.g., the date of his or her death,
effective date of a resignation or discharge, etc.), and the subsequent payment
of the aforementioned type of post-Severance compensation shall not operate to
postpone the timing of the Severance Date for purposes of the Plan.

         2.48 Sponsor. "Sponsor" shall mean Allergan, Inc., a Delaware
corporation, and any successor corporation or entity.

         2.49 Trust. "Trust" or "Trust Fund" shall mean the one or more trusts
created for funding purposes under the Plan.

         2.50 Trustee. "Trustee" shall mean the individual or entity acting as a
trustee of the Trust Fund.

         2.51 Valuation Date. "Valuation Date" shall mean the date as of which
the Trustee shall determine the value of the assets in the Trust Fund for
purposes of determining the value of each Account, which shall be each business
day in accordance with rules applied in a consistent and uniform basis.

                          ELIGIBILITY AND PARTICIPATION

Each Eligible Employee shall be eligible to participate in the Plan on his or
her Employment Commencement Date. If an Eligible Employee's employment with the
Company terminates after the Employee has become a Participant in the Plan, the
Employee shall become eligible to participate in the Plan immediately upon his
or her Reemployment Commencement Date.

                              PARTICIPANT DEPOSITS

         4.1 Election.

             (a) Each Eligible Employee may elect to defer the receipt of a
         portion of his or her Compensation and to have the deferred amount
         contributed directly by the Company to the Plan as Before Tax Deposits.
         Before Tax Deposits may be made only by means of payroll deduction.

             (b) Each Eligible Employee may elect to contribute to the Plan a
         portion of his or her Compensation as After Tax Deposits. After Tax
         Deposits may be made only by means of payroll deduction.

             (c) The Committee shall prescribe procedures to implement automatic
         enrollment elections, pursuant to which an Eligible Employee or, if
         limited to newly hired Eligible Employees as determined by the
         Committee, shall be deemed to have elected to defer the receipt of
         three percent (3%) of his or her Compensation and to have such deferred
         amount contributed directly by the Company to the Plan as Before Tax
         Deposits if such Eligible Employee fails to change or terminate the
         automatic election for any Plan Year within the time period prescribed
         by the Committee (or, in the case of newly hired Eligible Employee, he
         or she fails to change or terminate the automatic election within 30
         days of his or her hire date). Such procedures shall require that an
         Eligible Employee receive a written notice of explanation of the
         automatic election informing the Eligible Employee of the effective
         date of the automatic election, the automatic deferral percentage and
         his or her right to terminate the automatic election or to change the
         amount of his or her Before Tax Deposits made to the Plan as well as
         the procedures for exercising such rights and the timing for
         implementing a different election. An automatic election under this
         paragraph (c) shall be effective as of the first pay period of the Plan
         Year (or, in the case of newly hired Eligible Employee, the first pay
         period following the 30-day period beginning on his or her date of
         hire) and shall remain in effect until superseded by a subsequent
         election by the Eligible Employee. Amounts contributed directly by the
         Company to the Plan under this paragraph (c) shall be invested in the
         Balanced Fund described in Section 5.5(b) until superseded by a
         subsequent election by the Eligible Employee.

             (d) Notwithstanding anything in this Section to the contrary, a
         Participant who makes a hardship withdrawal pursuant to Section 8.1(e)
         shall not be permitted to make Before Tax Deposits or After Tax
         Deposits to the Plan for the 12-month period beginning as soon as
         administratively feasible following the date of the hardship
         withdrawal. In addition, a Participant who makes a withdrawal of After
         Tax Deposits (whether Matched Deposits or non-Matched Deposits)
         pursuant to Section 8.1(a) on or after July 1, 2000 shall not be
         permitted to make any After Tax or and Before Tax Deposits during the
         6-month period beginning as soon as administratively feasible following
         the date of the withdrawal unless the After Tax Deposits can also be
         withdrawn under Section 8.1(d) or

                                       15

<PAGE>   22

         the withdrawal is comprised solely of After Tax Deposits which are not
         Matched Deposits and which were contributed prior to July 1, 2000.

             (e) The Committee shall prescribe such procedures, either in
         writing or in practice, and provide such forms as are necessary or
         appropriate for each Participant and each Eligible Employee who will
         become a Participant to make Deposits pursuant to this Article IV.
         However, an election by a Participant shall not be adopted
         retroactively.

         4.2 Amount Subject to Election.

             (a) Participants may elect to contribute a whole percentage of his
         or her Compensation to the Plan as Before Tax Deposits not to exceed
         twenty percent (20%) when aggregated with the After Tax Deposits
         contributed by such Participant pursuant to paragraph (b) below.
         Notwithstanding the foregoing, no Participant shall be permitted to
         make Before Tax Deposits to the Plan during any taxable year in excess
         of $10,500, or such larger amount as may be determined by the Secretary
         of the Treasury pursuant to Code Section 402(g)(2), or which exceed the
         limitations set forth in Section 4.3. For purposes of the dollar
         limitation, the Before Tax Deposits of a Participant for any taxable
         year is the sum of all Before Tax Deposits under the Plan and all
         salary reduction amounts under any other qualified cash or deferred
         arrangement (as defined in Code Section 401(k)), a simplified employee
         pension (as defined in Code Section 408(k) and Code Section
         402(h)(1)(B)), a deferred compensation plan under Code Section 457, a
         trust described in Code Section 501(c)(18) and any salary reduction
         amount used to purchase an annuity contract under Code Section 403(b)
         whether or not sponsored by the Company but shall not include any
         amounts properly distributed as excess annual additions.

             (b) Each Participant may elect to contribute a whole percentage of
         his or her Compensation to the Plan as After Tax Deposits not to exceed
         twenty percent (20%) when aggregated with the amount of his or her
         Before Tax Deposits. Notwithstanding the foregoing, no Participant
         shall be permitted to make After Tax Deposits to the Plan during any
         Plan Year which exceed the limitations set forth in Section 6.13.

             (c) The Committee shall prescribe such procedures, either in
         writing or in practice, as it deems necessary or appropriate regarding
         the maximum amount that a Participant may elect to defer and the timing
         of such an election. These procedures shall apply to all individuals
         eligible to make an election described in Section 4.1. The Committee
         may, at any time during a Plan Year, require the suspension, reduction,
         or recharacterization of Before Tax Deposits or the suspension or
         reduction of After Tax Deposits of any Highly Compensated Employee such
         that the limitations of Section 4.2(a) and (b) are satisfied.

             (d) Notwithstanding paragraph (a), a Participant who makes a
         hardship withdrawal of Before Tax Deposits pursuant to Section 8.1(f)
         may not make Before Tax Deposits for the taxable year immediately
         following the taxable year of such hardship withdrawal that is in
         excess of the applicable limit under Code Section 402(g) for such

                                       16

<PAGE>   23

         immediately following taxable year less the amount of such
         Participant's Before Tax Deposits for the taxable year in which such
         Participant made the hardship withdrawal.

         4.3 Limitation on Compensation Deferrals. With respect to each Plan
Year, Compensation Deferral Contributions by a Participant for the Plan Year
shall not exceed the limitation on contributions by or on behalf of Highly
Compensated Participants under Code Section 401(k), as provided in this Section.
In the event that Compensation Deferral Contributions under the Plan by or on
behalf of Highly Compensated Participants exceed the limitations of this Section
for any reason, either such excess contributions shall be recharacterized as
After Tax Deposits or such excess contributions, adjusted for any income or loss
allocable thereto, shall be returned to the Participant, as provided in Section
4.5.

             (a) The Compensation Deferral Contributions by Participants for a
         Plan Year shall satisfy the Actual Deferral Percentage Test set forth
         in (i) below, or, to the extent not precluded by applicable
         regulations, the alternative Actual Deferral Percentage test set forth
         in (ii) below:

                 (i) The average Actual Deferral Percentage of Highly
              Compensated Participants for the Plan Year shall not be more than
              the prior Plan Year's average Actual Deferral Percentage of
              Participants who were not Highly Compensated Employees for the
              prior Plan Year multiplied by 1.25, or

                 (ii) The average Actual Deferral Percentage of Highly
              Compensated Participants for the Plan Year shall not be more than
              the prior Plan Year's Actual Deferral Percentage of Participants
              who were not Highly Compensated Employees for the prior Plan Year
              multiplied by 2.0, provided that the average Actual Deferral
              Percentage of Highly Compensated Participants does not exceed the
              average Actual Deferral Percentage of Participants who were not
              Highly Compensated Employees for the prior Plan Year by more than
              two (2) percentage points (or such lesser percentage as the
              Secretary of the Treasury shall prescribe to prevent the multiple
              use of the alternative limitation set forth in this Section
              4.3(a)(ii) with respect to any Highly Compensated Participants).

                 (iii) In the event the test under (i) above cannot be
              satisfied, the Committee shall determine if the use of the
              alternative test under (ii) above is available under regulations
              relating to the multiple use of the alternative limitation, as
              prescribed by the Secretary of the Treasury under Code Section
              401(m)(2)(A). If the Committee determines that the alternative
              test is not available, either the Actual Deferral Percentage or
              the Average Contribution Percentage (as defined in Section 6.11)
              for Highly Compensated Participants eligible to participate in the
              Plan and a plan of the Company or an Affiliated Company that is
              subject to the limitations of Code Sections 401 (k) and (m)
              including, if applicable, the Plan, shall be reduced in accordance
              with, and to the extent necessary to satisfy, the requirements of
              regulations issued under Code Section 401(m).

                                       17

              (b) Notwithstanding any other provisions of the Plan, for the
         purposes of the limitations of this Section 4.3 and Section 4.5 only,
         the following definitions shall apply:

                  (i) "Actual Deferral Percentage" shall mean, with respect to
              the group of Highly Compensated Participants and the group of all
              other Participants for a Plan Year, the ratios calculated
              separately and to the nearest one-hundredth of one percent for
              each Participant in such group, as follows:

                       (1) For a Highly Compensated Participant, the ratio of
                   such Participant's Compensation Deferral Contributions for
                   the current Plan Year to such Participant's Compensation for
                   the current Plan Year; provided, however, that the Actual
                   Deferral Percentage of a Highly Compensated Participant with
                   no Compensation Deferral Contributions made on his or her
                   behalf shall be zero.

                       (2) For any other Participant, the ratio of such
                   Participant's Compensation Deferral Contributions for the
                   preceding Plan Year to such Participant's Compensation for
                   the preceding Plan Year; provided, however, that the Actual
                   Deferral Percentage of a Participant with no Compensation
                   Deferral Contributions made on his or her behalf shall be
                   zero.

              To the extent determined by the Committee and in accordance with
         regulations issued by the Secretary of the Treasury, qualified
         nonelective contributions on behalf of a Participant that satisfy the
         requirements of Code Section 401(k)(3)(c)(ii) may also be taken into
         account for the purpose of determining the Actual Deferral Percentage
         of a Participant.

                  (ii) "Highly Compensated Participant" shall mean for any Plan
              Year any Participant who is a Highly Compensated Employee. A
              Participant is a Highly Compensated Employee for a particular Plan
              Year if he or she meets the definition of a Highly Compensated
              Employee in effect for that Plan Year. Similarly, a Participant is
              not a Highly Compensated Employee for a particular Plan Year if he
              or she does not meet the definition of a Highly Compensated
              Employee in effect for that Plan Year.

                  (iii) "Participant" shall mean any Eligible Employee who
              satisfied the requirements under Article III during the Plan Year,
              whether or not such Eligible Employee has elected to contribute to
              the Plan for such Plan Year.

                  (iv) "Compensation Deferral Contributions" shall mean amounts
              contributed to the Plan by a Participant as Before Tax Deposits
              pursuant to Section 4.2(a), including excess Before Tax Deposits
              (as defined in Section 4.4(a)) of Highly Compensated Participants
              but excluding (1) excess Before Tax Deposits of all other
              Participants that arise solely from Before Tax Deposits made under
              the Plan or plans of the Company, (2) Before Tax Deposits that are
              taken into account in the Average Contribution Percentage test (as
              defined

                                       18

<PAGE>   25

              in Section 6.11) provided that the Actual Deferral Percentage test
              is satisfied both with and without exclusions of these Before Tax
              Deposits, and (3) any deferrals properly distributed as excess
              Annual Additions. Compensation Deferral Contributions may include,
              at the election of the Company, any Company Contributions which
              meet the requirements for such inclusion under Code Section
              401(k)(3)(C).

                  (v) "Compensation" shall mean compensation as described below:

                      (1) Compensation means compensation determined by the
                  Company in accordance with the requirements of Code Section
                  414(s) and the regulations thereunder.

                      (2) For purposes of this Section 4.3, Compensation may, at
                  the Company's election, exclude amounts which are excludable
                  from a Participant's gross income under Code Section 125
                  (pertaining to cafeteria plans) and Code Section 402(e)(3)
                  (pertaining to 401(k) salary reductions). The Company may
                  change its election provided such change does not discriminate
                  in favor of Highly Compensated Employees.

                      (3) Compensation taken into account for any Plan Year
                  shall not exceed $150,000 as adjusted at the time and in such
                  manner as permitted under Code Section 401(a)(17)(B).

              (c) In the event the Plan satisfies the requirements of Code
         Sections 401(k), 401(a)(4) or 410(b) only if aggregated with one or
         more other plans which include arrangements under Code Section 401(k),
         then this Section 4.3 shall be applied by determining the Actual
         Deferral Percentages of Participants as if all such plans were a single
         plan, in accordance with regulations prescribed by the Secretary of the
         Treasury under Code Section 401(k). Any adjustments to the Actual
         Deferral Percentage of Participants who are not Highly Compensated
         Employees for the prior year shall be made in accordance with Notice
         98-1 and any superseding guidance. Plans may be aggregated in order to
         satisfy Code Sections 401(k) only if they have the same Plan Year and
         use the same Actual Deferral Percentage testing method.

              (d) For the purposes of this Section 4.3, the "Actual Deferral
         Percentage" for any Highly Compensated Participant who is a Participant
         under two or more Code Section 401(k) arrangements of the Company shall
         be determined by taking into account the Highly Compensated
         Participant's compensation under each such arrangement and
         contributions under each such arrangement which qualify for treatment
         under Code Section 401(k), in accordance with regulations prescribed by
         the Secretary of the Treasury under Code Section 401(k). If the
         arrangements have different Plan Years, this paragraph shall be applied
         by treating all such arrangements ending with or within the same
         calendar year as a single arrangement. Notwithstanding the foregoing,
         certain plans shall be treated as separate plans if mandatorily
         disaggregated pursuant to regulations under Code Section 401(k).

                                       19

<PAGE>   26

              (e) For purposes of the Actual Deferral Percentage test,
         Compensation Deferral Contributions must be made before the last day of
         the twelve-month period immediately following the Plan Year to which
         such contributions relate.

              (f) The determination and treatment of Compensation Deferral
         Contributions and the Actual Deferral Percentage of any Participant
         shall satisfy such other requirements as may be prescribed by the
         Secretary of the Treasury.

              (g) The Committee shall keep or cause to have kept such records as
         are necessary to demonstrate that the Plan satisfies the requirements
         of Code Section 401(k) and (m) and the regulations thereunder, in
         accordance with regulations prescribed by the Secretary of the
         Treasury.

         4.4 Provisions for Return of Excess Before Tax Deposits Over $7,000.

              (a) In the event that due to error or otherwise, an amount of a
         Participant's Compensation in excess of the $7,000 limitation (after
         application of any necessary adjustment) described in Section 4.2(a) is
         deferred under the Plan in any calendar year pursuant to such
         Participant's Compensation deferral agreement (but without regard to
         amounts deferred under any other plan) the excess Before Tax Deposits,
         if any, together with income allocable to such amount shall be returned
         to the Participant (after withholding applicable federal, state and
         local taxes due on such amounts) on or before the first April 15
         following the close of the calendar year in which such excess
         contribution is made; provided, however, if there is a loss allocable
         to the excess Before Tax Deposits, the amount distributed shall be the
         amount of the excess as adjusted to reflect such loss. Any Company
         Contributions allocated to the Participant's Matched Deposits pursuant
         to Section 6.3(b) which are attributable to any excess Before Tax
         Deposits by a Participant, and any income or loss allocable to such
         Company Contributions, shall either be returned to the Company or
         applied to reduce any future Company Contributions by the Company.

              (b) The amount of income or loss attributable to any excess Before
         Tax Deposits described in paragraph (a) above shall be equal to the sum
         of the following:

                  (i) The income or loss allocable to the Participant's Before
              Tax Deposits Account for the Plan Year multiplied by a fraction,
              the numerator of which is the excess Before Tax Deposits as
              determined under paragraph (a) above, and the denominator of which
              is the balance of the Participant's Before Tax Deposits Account as
              of the last day of the Plan Year, without regard to any income or
              loss allocable to such Account during the Plan Year; and

                  (ii) The amount of allocable income or loss for the Gap Period
              using the "safe harbor" method set forth in regulations prescribed
              by the Secretary of the Treasury under Code Section 402(g). Under
              the "safe harbor" method, such allocable income or loss is equal
              to 10% of the amount calculated under

                                       20

<PAGE>   27

              Section 4.4(b)(i) above, multiplied by the number of calendar
              months from the last day of the Plan Year until the date of
              distribution of the Participant's excess Before Tax Deposits. A
              distribution on or before the 15th of the month is treated as made
              on the last day of the preceding month, a distribution after the
              15th of the month is treated as made on the first day of the next
              month.

              (c) For the purpose of this Section 4.4, "Gap Period" shall mean
         the period between the last day of the Plan Year and the date of
         distribution of any excess Before Tax Deposits.

              (d) In accordance with procedures as may be established, either in
         writing or in practice, by the Committee, not later than March 1 of a
         calendar year a Participant may submit a claim to the Committee in
         which he or she certifies in writing the specific amount of his or her
         Before Tax Deposits for the preceding calendar year which, when added
         to amounts deferred for such calendar year under other plans or
         arrangements described in Code Sections 401(k), 408(k) or 403(b), will
         cause the Participant to exceed the $7,000 limitation as described in
         Section 4.2(a) for such preceding calendar year. Notwithstanding the
         amount of the Participant's Before Tax Deposits under the Plan for such
         preceding calendar year, the Committee shall treat the amount specified
         by the Participant in his or her claim as a Before Tax Deposit in
         excess of the $7,000 limitation (after application of any necessary
         adjustment) for such calendar year and return it to the Participant in
         accordance with Section 4.4(a) above. A Participant is deemed to notify
         the Committee of any excess Before Tax Deposits that arise by taking
         into account only those Before Tax Deposits made to the Plan and other
         plans of the Company.

              (e) Any Before Tax Deposits in excess of the $7,000 limitation
         (after application of any necessary adjustment) described in Section
         4.2(a) which are distributed to a Participant in accordance with this
         Section, shall to the extent required by regulations issued by the
         Secretary of the Treasury be treated as Annual Additions under Article
         XIII for the Plan Year for which the excess Before Tax Deposits were
         made, unless such amounts are distributed no later than the first April
         15th following the close of the Participant's taxable year.

              (f) The Committee shall not be liable to any Participant (or his
         or her Beneficiary, if applicable) for any losses caused by a mistake
         in calculating the amount of any Participant's excess Before Tax
         Deposits or the income or losses attributable thereto.

         4.5 Provision for Recharacterization or Return of Excess Deferrals by
Highly Compensated Participants. The provisions of this Section 4.5 shall be
applied after implementation of the provisions of Section 4.4.

              (a) The Committee shall determine in accordance with the
         procedures set forth in Section 4.3, as soon as is reasonably possible
         following the close of each Plan Year, the extent (if any) to which
         deferral treatment under Code Section 401(k) may not be available for
         Compensation Deferral Contributions on behalf of any Highly Compensated
         Participants. If, pursuant to these determinations by the Committee, a

                                       21

<PAGE>   28

         Highly Compensated Participant's Compensation Deferral Contributions
         are not eligible for tax-deferral treatment then, as determined by the
         Committee, either (i) any excess Compensation Deferral Contributions
         shall be recharacterized as After Tax Deposits in accordance with
         regulations issued under Code Section 401(k), or (ii) any excess
         Compensation Deferral Contributions together with any income or loss
         allocable thereto shall be returned to the Highly Compensated
         Participant (after withholding applicable federal, state, and local
         taxes due on such amounts). Such return or recharacterization shall be
         made within the first two and one-half (2-1/2) months following the
         close of the Plan Year for which such excess deferrals were made,
         provided however, that if any excess deferrals and income or loss
         allocable thereto are, due to error or otherwise, not returned by such
         date, such amounts as are required to be returned shall be returned not
         later than the end of the first Plan Year following the Plan Year for
         which such excess deferrals were made.

              (b) For purposes of satisfying the Actual Deferral Percentage test
         of Section 4.3(a), the amount of any excess Compensation Deferral
         Contributions by a Highly Compensated Participant shall be determined
         by the Committee by application of a leveling method under which the
         Compensation Deferral Contributions of the Highly Compensated
         Participant who has the highest dollar amount of Compensation Deferral
         Contributions for such Plan Year is reduced to the extent required to
         cause such Highly Compensated Participant's Compensation Deferral
         Contributions to equal the Compensation Deferral Contributions of the
         Highly Compensated Participant with the next highest Compensation
         Deferral Contributions; provided, however, if a lesser amount, when
         added to the total dollar amount already returned under this paragraph
         (b), equals the total excess Compensation Deferral Contributions that
         are required to be returned to enable the Plan to satisfy the Actual
         Deferral Percentage test, the lesser amount shall be returned. This
         process shall be repeated until the Plan satisfies the Actual Deferral
         Percentage test.

              (c) The amount of income or loss attributable to any excess
         Compensation Deferral Contributions by a Highly Compensated Participant
         for a Plan Year shall be equal to the sum of the following:

                  (i) The income or loss allocable to the Highly Compensated
              Participant's Compensation Deferral Contribution Accounts for the
              Plan Year multiplied by a fraction, the numerator of which is the
              excess Compensation Deferral Contribution as determined under
              Section 4.3, and the denominator of which is the balance of the
              Highly Compensated Participant's Compensation Deferral
              Contribution Accounts as of the last day of the Plan Year without
              regard to any income or loss allocable to such Accounts during the
              Plan Year; and

                  (ii) The amount of allocable income or loss for the Gap Period
              using the "safe harbor" method set forth in the regulations
              prescribed by the Secretary of the Treasury under Code Section
              401(k). Under the "safe harbor" method, such allocable income or
              loss is equal to 10% of the amount calculated under Section
              4.5(c)(i) above, multiplied by the number of calendar months from
              the last day of the Plan Year until the date of distribution of
              the Participant's excess

                                       22

<PAGE>   29

              Compensation Deferral Contribution. A distribution on or before
              the 15th of the month is treated as made on the last day of the
              preceding month, a distribution after the 15th of the month is
              treated as made on the first day of the next month.

              (d) For the purpose of this Section 4.5 the following shall apply:

                  (i) "Compensation Deferral Contribution Accounts" shall mean
              the Participant's Before Tax Deposits Account and shall mean any
              other accounts of the Participant to which Company Contributions
              has been allocated where such Company Contributions has been
              included as Compensation Deferral Contributions pursuant to
              Section 4.3(b)(iv).

                  (ii) "Gap Period" shall mean the period beginning with the
              last day of the Plan Year and the date of distribution of any
              excess Compensation Deferral Contributions.

              (e) For purposes of this Section, the amount of Compensation
         Deferral Contributions by a Participant who is not a Highly Compensated
         Participant for a Plan Year shall be reduced by any Before Tax Deposits
         which have been distributed to the Participant under Section 4.4, in
         accordance with regulations prescribed by the Secretary of the Treasury
         under Code Section 401(k).

              (f) In the event that the Committee determines that an amount to
         be deferred pursuant to the Compensation deferral agreement provided in
         Section 4.1 would cause Company Contributions under this and any other
         tax-qualified retirement plan maintained by the Company to exceed the
         applicable deduction limitations contained in Code Section 404, or to
         exceed the maximum Annual Addition determined in accordance with
         Article XIII, the Committee may treat such amount in accordance with
         the rules set forth above in Section 4.5(a).

              (g) The Committee shall not be liable to any Participant (or his
         or her Beneficiary, if applicable) for any losses caused by a mistake
         in calculating the amount of any Participant's excess Compensation
         Deferral Contribution or the income or losses attributable thereto.

              (h) To the extent required by regulations under Code Sections
         401(k) or 415, any excess Compensation Deferral Contributions with
         respect to a Highly Compensated Participant shall be treated as Annual
         Additions under Article XIII for the Plan Year for which the excess
         Compensation Deferral Contributions were made, notwithstanding the
         distribution of such excess in accordance with the provisions of this
         Section.

         4.6 Termination, Change in Rate, or Resumption of Deferrals.

              (a) A Participant may, at any time, terminate, change the rate, or
         resume Before Tax Deposits or After Tax Deposits in 1% increments.

                                       23

<PAGE>   30

              (b) The right of a Participant to make Deposits shall cease during
         any Period of Severance.

              (c) Any termination, change in rate or resumption of Before Tax
         Deposits or After Tax Deposits made by a Participant pursuant to
         paragraph (a) above shall be effective as of the following pay period
         or, if later, as soon as administratively feasible.

         4.7 Character of Deposits. Before Tax Deposits shall be treated as
Company Contributions for purposes of Code Sections 401(k) and 414(h). After Tax
Deposits shall not constitute "qualified voluntary employee contributions" under
Code Section 219 (relating to the deductibility of those amounts).

         4.8 Rollover Contributions.

             (a) Pursuant to procedures as the Committee may prescribe (either
         in writing or practice), an Eligible Employee may make a Rollover
         Contribution to the Plan. "Rollover Contribution" shall mean a
         contribution by an Eligible Employee as the result of a distribution
         from another "qualified trust" (as defined in Code Section 401) which
         is exempt from tax under Code Section 501, but only if such
         contribution:

                  (i) Is received by the Committee not later than 60 days after
              the distribution was received by an Eligible Employee; or

                  (ii) Is the result of a trustee-to-trustee transfer of assets
              between two or more qualified plans; or

                  (iii) Is the result of a transfer of assets from an individual
              retirement arrangement or annuity (as defined in Code Section 408)
              and such individual retirement arrangement or annuity was created
              solely from a distribution or distributions from a qualified plan;
              or

                  (iv) Is an "Eligible Rollover Distribution".

              (b) A Rollover Contribution shall not be considered a Participant
         Deposit.

              (c) An Eligible Employee's Rollover Contribution made pursuant the
         rules of this Section 4.8 shall be held in a separate Rollover Account
         for the Eligible Employee. A Rollover Account will not share in any
         allocations of Company Contributions or Forfeitures under Section 6.3.

                                    ARTICLE V
                      TRUST FUND AND COMPANY CONTRIBUTIONS

         5.1 General. All contributions made under the Plan and investments made
and property of any kind or character acquired with any such funds or otherwise
contributed, and all income, profits, and proceeds derived therefrom, shall be
held in Trust and shall be held and administered by the Trustee in accordance
with the provisions of the Plan and Trust Agreement.

         5.2 Single Trust. Assets of the Trust shall be held in a separate fund
which shall consist of the Trust Fund. Individual Participant interests in the
Trust Fund shall be reflected in the Accounts maintained for the Participants.
Notwithstanding the foregoing, the Trust Fund shall be treated as a single trust
for purposes of investment and administration, and nothing contained herein
shall require a physical segregation of assets for any fund or for any Account
maintained under the Plan.

         5.3 Company Contributions. Subject to the limitations of Article XIII,
the suspension provisions of Section 8.1 and to the extent that the Company has
current or accumulated profits, the Company shall contribute to the Plan in
accordance with the following rules:

             (a) The Company shall contribute and allocate Matching
         Contributions on a pay period basis which, when added to Forfeitures
         available after application of Section 6.3, is equal to:

                 (i) 75% of each Participant's Matched Deposits for the pay
             period which are not in excess of two percent (2%) of such
             Participant's Compensation.

                 (ii) 50% of each Participant's Matched Deposits for the pay
             period which are in excess of two percent (2%) of such
             Participant's Compensation but not in excess of three percent (3%)
             of such Participant's Compensation.

                 (iii) 25% of each Participant's Matched Deposits for the pay
             period which are in excess of three percent (3%) of such
             Participant's Compensation.

              The Board of Directors, acting upon the advice and direction of
         the Committee, may authorize and direct that Matching Contributions
         (expressed as a percentage of Participants' Matched Deposits as set
         forth above) be changed from time to time from a minimum of 0% to a
         maximum of 100%.

              (b) The Company shall contribute and allocate additional Matching
         Contributions on the last day of each Plan Year which when added to
         Forfeitures available after application of Section 6.3, is equal to the
         difference, if any, between the amount of each Participant's Matching
         Contributions determined under paragraph (a) and the amount of such
         Participant's Matching Contributions if paragraph (a) was applied on a
         Plan Year basis instead of a pay period basis.

                                       25

<PAGE>   32

              (c) The Company shall contribute amounts sufficient to satisfy the
         reinstatement requirements of Section 8.7 to the extent Forfeitures are
         insufficient to satisfy the reinstatement requirement of Section 8.7
         and any plan expense requirements of Section 9.11 if so directed and at
         such times as may be determined by the Committee.

         5.4 Form of Company Contributions. The Company's contributions to the
Trust Fund shall be paid in cash, property, or Company Stock as the Company may
from time to time determine.

         5.5 Investment of Trust Assets.

              (a) The manner in which assets of the Trust will be invested shall
         be chosen by the Committee at its discretion, although the Committee
         may delegate the management to one or more Investment Managers
         appointed pursuant to Section 5.15. Notwithstanding the foregoing,
         Matching Contributions shall be invested in Company Stock except to the
         extent invested pursuant to Section 5.5(e). Employer contributions made
         under the SmithKline Beckman Corporation Savings and Investment Plan
         and transferred to the Plan shall be invested at the discretion of the
         Committee through June 30, 2000.

              (b) The Committee may establish separate investment funds under
         the Plan, with each fund representing an investment alternative
         available to Participants for the investment of their Accounts as
         provided in Section 5.5(c) and (d) below. Each Participant shall have a
         subaccount under the Plan corresponding to the Participant's interest
         which is allocated to each investment fund. Each such subaccount may be
         valued separately. The Committee may, at its discretion, establish
         alternative investment funds or eliminate any previously established
         funds, including but not limited to the following types of investment
         funds:

                  (i) The Interest Income Fund investing in group annuity
              contracts with major insurance companies.

                  (ii) The Balanced Fund investing in common stocks, bonds,
              government securities and similar types of investments.

                  (iii) The Equity Fund investing in a mutual fund which may
              invest in equity securities, bonds, preferred stocks, and
              interest-bearing cash investments.

                  (iv) The Company Stock Fund consisting exclusively of Company
              Stock.

              Notwithstanding the establishment of separate investment funds, up
         to one hundred percent (100%) of the assets of the Plan may be invested
         in Company Stock.

              (c) A Participant may elect the investment fund to which his or
         her Before Tax Deposits or After Tax Deposits are invested under the
         Plan or may change such

                                       26

<PAGE>   33

         elections at any time; provided, however, that any allocations among
         the investment funds shall be made in 1% increments. Any change in
         investment funds shall be effective as soon as administratively
         feasible. Any investment elections shall be limited to the investment
         funds currently offered by the Committee and currently available to
         Participants pursuant to paragraph (b) above. A Participant shall
         effect such an election by properly completing and submitting the form
         authorized by the Committee for this purpose.

              (d) A Participant may elect at any time to transfer amounts
         accumulated in his or her Before Tax Deposits Account, After Tax
         Deposits Account, or Rollover Account among any of the investment funds
         currently offered by the Committee and currently available to the
         Participant, provided, however, the total amount transferred shall be
         in increments of 1% of the amount accrued in such accounts. As of July
         1, 2000, the foregoing investment discretion shall be permitted for
         amounts attributable to employer contributions made under the
         SmithKline Beckman Corporation Savings and Investment Plan and
         transferred to the Plan. A Participant shall effect such transfer in
         the manner authorized by the Committee.

              (e) Notwithstanding the requirement of paragraph (a) above that
         Matching Contributions be invested in the Company Stock Fund, any
         Participant on or after the date he or she attains age 55 may elect
         that (i) all amounts allocated to his or her Company Contribution
         Account which are held in the Company Stock Fund and (ii) any future
         Matching Contributions that may be allocated to his or her Company
         Contribution Account, be invested in any of the investment funds
         currently offered by the Committee and currently available to the
         Participant. A Participant shall make any election, and may change any
         election, at such times and in accordance with the requirements imposed
         by Sections 5.5(c) and (d) above.

              (f) Amounts invested in any one of the investment funds shall not
         share in gains and losses experienced by any other fund.

              (g) Notwithstanding the establishment of separate investment funds
         within the Trust, the Trust shall at all times constitute a single
         trust.

              (h) Notwithstanding anything to the contrary in this Section 5.5
         or Section 4.1 or Section 8.1, the following additional transfer and
         withdrawal restrictions shall apply to all Participants who are
         Insiders. For the purpose of this Section 5.5, the term "Insider" shall
         mean any Participant who is directly or indirectly the beneficial owner
         of more than 10% of any class of any equity security (other than an
         exempted security) of the Sponsor (or the Company) which is registered
         pursuant to Section 12 of the Securities Exchange Act of 1934 (the
         "Exchange Act") or who is a "director" or an "officer" of the Sponsor
         or the Company as those terms are interpreted for the purpose of
         determining persons subject to Section 16 of the Exchange Act.

              Fund (pursuant to Sections 8.1 or 8.13), may not for a period of
              six months following the Participant's election to so transfer
              funds, withdraw cash or take a loan, as the case may be, make an
              election to transfer amounts from another fund into the Company
              Stock Fund.

                  (ii) Any Insider who transfers amounts invested in a fund
              other than the Company Stock Fund into the Company Stock Fund, may
              not for a period of six months following the Participant's
              election to so transfer funds make an election to (1) transfer
              amounts from the Company Stock Fund into another fund, (2)
              withdraw cash or take a loan in a transaction that results in the
              liquidation of amounts in the Company Stock Fund or (3) utilize
              the diversification rule of Section 5.12 of the Allergan Inc.

              then in existence that would result in the transfer out of a
              Company equity securities fund.

              (i) It is intended that to the extent a Participant may direct the
         investment of his or her Accounts under the Plan that the Plan
         constitute a plan described in Section 404(c) of ERISA and the
         regulations thereunder, and neither the Company, Committee, nor any
         fiduciary with respect to the Plan who is employed by the Company shall
         be liable for investment losses sustained by any Participant or
         Beneficiary as a direct and necessary result of the investment
         instructions given by such Participant or Beneficiary. Such fiduciaries
         set forth in the preceding sentence shall be under no duty to question
         the investment direction of the Participant or to advise a Participant
         as to the manner in which his or her Accounts is to be invested. The
         fact that an investment option is offered shall not be construed to be
         a recommendation of investment.

         5.6 Irrevocability. The Company shall have no right or title to, nor
interest in, the contributions made to the Trust Fund, and no part of the Trust
Fund shall revert to the Company except that on or after the original Effective
Date funds may be returned to the Company as follows:

              (a) In the case of a Company Contribution which is made by a
         mistake of fact, at the Company's written request that contribution may
         be returned to the Company within one (1) year after it is made.

              (b) All Company Contributions contributed to the Trust are hereby
         conditioned upon the Plan satisfying all of the requirements of Code
         Section 401(a). If the Plan does not qualify, at the Company's written
         election the Plan may be revoked and all such contributions may be
         returned to the Company within one year after the date of Internal
         Revenue Service denial of the qualification of the Plan. Upon such a
         revocation the affairs of the Plan and Trust shall be terminated and
         wound up as the Company shall direct.

                                       28

<PAGE>   35

              (c) All Company Contributions to the Plan are conditioned upon the
         deductibility of those contributions under Code Section 404. To the
         extent a deduction is disallowed, at the Company's written request the
         contribution may be returned to the Company within one year after the
         disallowance.

              (d) In the event that the Plan is terminated when there are
         amounts remaining in the Suspense Account, the excess funds may revert
         to the Company to the extent provided in Section 13.6.

         5.7 Company, Committee and Trustee Not Responsible for Adequacy of
Trust Fund.

              (a) The Company, Committee, and the Trustee shall not be liable or
         responsible for the adequacy of the Trust Fund to meet and discharge
         any or all payments and liabilities hereunder. All Plan benefits will
         be paid only from the Trust assets, and neither the Company, the
         Committee nor the Trustee shall have any duty or liability to furnish
         the Trust with any funds, securities or other assets except as
         expressly provided in the Plan.

              (b) Except as required under the Plan or Trust or under Part 4 of
         Subtitle B of Title I of ERISA, the Company shall not be responsible
         for any decision, act or omission of the Trustee, the Committee, or the
         Investment Manager (if applicable), and shall not be responsible for
         the application of any moneys, securities, investments or other
         property paid or delivered to the Trustee.

         5.8 Certain Offers for Company Stock. Notwithstanding any other
provision of the Plan to the contrary, in the event an offer shall be received
by the Trustee (including but not limited to a tender offer or exchange offer
within the meaning of the Securities Exchange Act of 1934, as from time to time
amended and in effect) to acquire any or all shares of Company Stock held by the
Trust (an "Offer"), the discretion or authority to sell, exchange or transfer
any of such shares of Company Stock shall be determined in accordance with the
following rules:

              (a) The Trustee shall have no discretion or authority to sell,
         exchange or transfer any Company Stock pursuant to an Offer except to
         the extent, and only to the extent, that the Trustee is timely directed
         to do so in writing by each Participant with respect to shares of
         Company Stock that are allocated to such Participant's Accounts.

              (b) To the extent there remains any residual fiduciary
         responsibility with respect to Company Stock pursuant to an Offer after
         application of paragraph (a) above, the Trustee shall sell, exchange or
         transfer such Company Stock as directed by the Committee or as directed
         by an independent fiduciary if duly appointed by the Sponsor. To the
         extent the Committee or an independent fiduciary is required to
         exercise any residual fiduciary responsibility with respect to an
         Offer, the Committee or independent fiduciary shall take into account
         in exercising its fiduciary judgment, unless it is clearly imprudent to
         do so, directions timely received from Participants, as such directions
         are most indicative of what action is in the best interests of
         Participants. Further, the Committee or independent fiduciary, in
         addition to taking into consideration any relevant

                                       29

<PAGE>   36

         financial factors bearing on any such decision, shall take into
         consideration any relevant non-financial factors, including, but not
         limited to, the continuing job security of Participants as employees of
         the Sponsor or any Affiliated Company, conditions of employment,
         employment opportunities and other similar matters, and the prospect of
         the Participants and prospective Participants for future benefits under
         the Plan.

              (c) Upon timely receipt of such instructions, the Trustee shall,
         subject to the provisions of paragraphs (e) and (o) of this Section,
         sell, exchange or transfer pursuant to such Offer, only such shares as
         to which such instructions were given. The Committee shall use its best
         efforts to communicate or cause to be communicated to each Participant
         the consequences of any failure to provide timely instructions to the
         Trustee.

              (d) In the event, under the terms of an Offer or otherwise, any
         shares of Company Stock tendered for sale, exchange or transfer
         pursuant to such Offer may be withdrawn from such Offer, the Trustee
         shall follow such instructions respecting the withdrawal of such shares
         from such Offer in the same manner and the same proportion as shall be
         timely received by the Trustee from the Participants entitled under
         this paragraph (a) to give instructions as to the sale, exchange or
         transfer of shares pursuant to such Offer.

              (e) In the event that an Offer for fewer than all of the shares of
         Company Stock held by the Trustee in the Trust shall be received by the
         Trustee, each Participant shall be entitled to direct the Trustee as to
         the acceptance or rejection of such Offer (as set forth herein) with
         respect to the largest portion of such Company Stock as may be possible
         given the total number or amount of shares of Company Stock the Plan
         may sell, exchange or transfer pursuant to the Offer based upon the
         instructions received by the Trustee from all other Participants who
         shall timely instruct the Trustee pursuant to this paragraph to sell,
         exchange or transfer such shares pursuant to such Offer, each on a pro
         rata basis in accordance with the maximum number of shares each such
         Participant would have been permitted to direct under paragraph (a) had
         the Offer been for all shares of Company Stock held in the Trust.

              (f) In the event an Offer is received by the Trustee and
         instructions have been solicited from Participants regarding such
         Offer, and prior to termination of such Offer, another Offer is
         received by the Trustee for the Company Stock subject to the first
         Offer, the Trustee shall inform the Committee of such other Offer and
         the Committee shall use its best efforts under the circumstances to
         solicit instructions from the Participants (i) with respect to
         securities tendered for sale, exchange or transfer pursuant to the
         first Offer, whether to withdraw such tender, if possible, and, if
         withdrawn, whether to tender any Company Stock so withdrawn for sale,
         exchange or transfer pursuant to the second Offer and (ii) with respect
         to Company Stock not tendered for sale, exchange or transfer pursuant
         to the first Offer, whether to tender or not to tender such Company
         Stock for sale, exchange or transfer pursuant to the second Offer. The
         Trustee shall follow all such instructions received in a timely manner
         from Participants in the same manner and in the same proportion as
         provided in paragraph (a) of this Section. With respect to any further
         Offer for any Company Stock received by the Trustee and subject to any
         earlier Offer

                                       30

<PAGE>   37

         (including successive Offers from one or more existing offers), the
         Trustee shall act in the same manner as described above.

              (g) With respect to any Offer received by the Trustee, the Trustee
         shall inform the Sponsor of such Offer and the Sponsor shall
         distribute, at its expense, copies of all relevant material including
         but not limited to material filed with the Securities and Exchange
         Commission with such Offer or regarding such Offer, which shall seek
         confidential written instructions from each Participant who is entitled
         to respond to such Offer pursuant to paragraph (a). The identities of
         Participants, the amount of Company Stock allocated to their ESOP
         Accounts, and the Compensation of each Participant shall be determined
         from the list of Participants delivered to the Sponsor by the Committee
         which shall take all reasonable steps necessary to provide the Sponsor
         with the latest possible information.

              (h) The Sponsor shall distribute and/or make available to each
         Participant who is entitled to respond to an Offer pursuant to
         paragraph (a), an instruction form to be used by each such Participant
         who wishes to instruct the Trustee. The instruction form shall state
         that (i) if the Participant fails to return an instruction form to the
         Trustee by the indicated deadline, the Company Stock with respect to
         which he or she is entitled to give instructions shall not be sold,
         exchanged or transferred pursuant to such Offer, (ii) the Participant
         shall be a named fiduciary (as described in paragraph (m) below) with
         respect to all shares of Company Stock for which he or she is entitled
         to give instructions, and (iii) the Company acknowledges and agrees to
         honor the confidentiality of the Participant's instructions to the
         Trustee.

              (i) Each Participant may choose to instruct the Trustee in one of
         the following two ways: (i) not to sell, exchange or transfer any
         shares of Company Stock for which he or she is entitled to give
         instructions, or (ii) to sell, exchange or transfer all Company Stock
         for which he or she is entitled to give instructions. The Sponsor shall
         follow up with additional mailings and postings of bulletins, as
         reasonable under the time constraints then prevailing, to obtain
         instructions from Participants not otherwise responding to such
         requests for instructions. Subject to paragraph (e), the Trustee shall
         then sell, exchange or transfer shares according to instructions from
         Participants, except that shares for which no instructions are received
         shall not be sold, exchanged or transferred unless directed otherwise
         as provided in paragraph (b) above.

              (j) The Sponsor shall furnish former Participants who have
         received distributions of Company Stock so recently as to not be
         shareholders of record with the information given to Participants
         pursuant to paragraphs (g), (h) and (i) of this Section. The Trustee
         shall then sell, exchange or transfer shares according to instructions
         from such former Participants, except that shares for which no
         instructions are received shall not be sold, exchanged or transferred.

              (k) Neither the Company, the Committee nor the Trustee shall
         express any opinion or give any advice or recommendation to any
         Participant concerning the Offer, nor shall they have any authority or
         responsibility to do so.

                                       31

<PAGE>   38

              (l) The Trustee shall not reveal or release a Participant's
         instructions to the Company, its officers, directors, employees, or
         representatives. If some but not all Company Stock held by the Trust is
         sold, exchanged, or transferred pursuant to an Offer, the Company, with
         the Trustee's cooperation, shall take such action as is necessary to
         maintain the confidentiality of Participant's records including,
         without limitation, establishment of a security system and procedures
         which restrict access to Participant records and retention of an
         independent agent to maintain such records. If an independent record
         keeping agent is retained, such agent must agree, as a condition of its
         retention by the Sponsor, not to disclose the composition of any
         Participant Accounts to the Company, its officers, directors,
         employees, or representatives. The Company acknowledges and agrees to
         honor the confidentiality of Participants' instructions to the Trustee.

              (m) Each Participant shall be a named fiduciary (as that term is
         defined in Section 402(a)(2) of ERISA) with respect to Company Stock
         allocated to his or her Accounts under the Plan solely for purposes of
         exercising the rights of a shareholder with respect to an Offer
         pursuant to this Section 5.8 and voting rights pursuant to Section 5.9.

              (n) To the extent that an Offer results in the sale of Company
         Stock in the Trust, the Committee or the Participants, if so permitted
         under the terms of the Plan, shall instruct the Trustee as to the
         investment of the proceeds of such sale.

              (o) In the event a court of competent jurisdiction shall issue to
         the Plan, the Committee, the Sponsor or the Trustee an opinion or
         order, which shall, in the opinion of counsel to the Committee, the
         Sponsor or the Trustee, invalidate, in all circumstances or in any
         particular circumstances, any provision or provisions of this Section
         regarding the determination to be made as to whether or not Company
         Stock held by the Trustee shall be sold, exchanged or transferred
         pursuant to an Offer or cause any such provision or provisions to
         conflict with securities laws, then, upon notice thereof to the
         Committee, the Sponsor or the Trustee, as the case may be, such invalid
         or conflicting provisions of this Section shall be given no further
         force or effect. In such circumstances, the Trustee shall continue to
         follow instructions received from Participants, to the extent such
         instructions have not been invalidated by such order or opinion. To the
         extent the Trustee is required by such opinion or order to exercise any
         residual fiduciary responsibility with respect to such Offer, the
         Sponsor shall appoint an independent fiduciary who shall exercise such
         residual fiduciary responsibility as provided in paragraph (b) above
         and shall direct the Trustee as to whether or not Company Stock held by
         the Trustee shall be sold, exchanged or transferred pursuant to such
         Offer.

         5.9 Voting of Company Stock. Notwithstanding any other provision of the
Plan to the contrary, the Trustee shall have no discretion or authority to vote
Company Stock held in the Trust on any matter presented for a vote by the
stockholders of the Company except in accordance with timely directions received
by the Trustee from either the Committee or Participants, depending on who has
the right to direct the voting of such Company Stock as provided in the
following provisions of this Section 5.9.

                                       32

<PAGE>   39

              (a) All Company Stock held in the Trust Fund shall be voted by the
         Trustee as the Committee directs in its absolute discretion, except as
         provided in this Section 5.9(a).

                  (i) If the Sponsor has a registration-type class of securities
              (as defined in Code Section 409(e)(4)), then with respect to all
              corporate matters, each Participant shall be entitled to direct
              the Trustee as to the voting of all Company Stock allocated and
              credited to his or her Accounts.

                  (ii) If the Sponsor does not have a registration-type class of
              securities, then only with respect to such matters as the approval
              or disapproval of any corporate merger or consolidation,
              recapitalization, reclassification, liquidation, dissolution, sale
              of substantially all assets of trade or business, or such similar
              transactions as may be prescribed in Code Section 409(e)(4) and
              the regulations thereunder, each Participant shall be entitled to
              direct the Trustee as to the voting of all Company Stock allocated
              and credited to the his or her Accounts.

              (b) To the extent there remains any residual fiduciary
         responsibility with respect to the voting of Company Stock after
         application of paragraph (a) above, the Trustee shall vote such Company
         Stock as directed by the Committee or as directed by an independent
         fiduciary if duly appointed by the Sponsor. To the extent the Committee
         or an independent fiduciary is required to exercise any residual
         fiduciary responsibility with respect to the voting of Company Stock,
         the Committee or independent fiduciary shall take into account in
         exercising its fiduciary judgment, unless it is clearly imprudent to do
         so, directions timely received from Participants, as such directions
         are most indicative of what action is in the best interests of
         Participants. Further, the Committee or independent fiduciary, in
         addition to taking into consideration any relevant financial factors
         bearing on any such decision, shall take into consideration any
         relevant non-financial factors, including, but not limited to, the
         continuing job security of Participants as employees of the Sponsor or
         any Affiliated Company, conditions of employment, employment
         opportunities and other similar matters, and the prospect of the
         Participants and prospective Participants for future benefits under the
         Plan.

              (c) All Participants entitled to direct such voting shall be
         notified by the Sponsor, pursuant to its normal communications with
         shareholders, of each occasion for the exercise of such voting rights
         within a reasonable time before such rights are to be exercised. Such
         notification shall include all information distributed to shareholders
         either by the Sponsor or any other party regarding the exercise of such
         rights. Such Participants shall be so entitled to direct the voting of
         fractional shares (or fractional interests in shares), provided,
         however, that the Trustee may, to the extent possible, vote the
         combined fractional shares (or fractional interests in shares) so as to
         reflect the aggregate direction of all Participants giving directions
         with respect to fractional shares (or fractional interests in shares).
         To the extent that a Participant shall fail to direct the Trustee as to
         the exercise of voting rights arising under any Company Stock credited
         to his or her Accounts, such Company Stock shall not be voted unless
         the Trustee is directed

                                       33

<PAGE>   40

         otherwise as provided in paragraph (b) above. The Trustee shall
         maintain confidentiality with respect to the voting directions of all
         Participants.

              (d) Each Participant shall be a named fiduciary (as that term is
         defined in Section 402(a)(2) of ERISA) with respect to Company Stock
         for which he or she has the right to direct the voting under the Plan
         but solely for the purpose of exercising voting rights pursuant to this
         Section 5.9 or certain Offers pursuant to Section 5.8.

              (e) In the event a court of competent jurisdiction shall issue an
         opinion or order to the Plan, the Committee, the Sponsor or the
         Trustee, which shall, in the opinion of counsel to the Committee, the
         Sponsor or the Trustee, invalidate under ERISA, in all circumstances or
         in any particular circumstances, any provision or provisions of this
         Section regarding the manner in which Company Stock held in the Trust
         shall be voted or cause any such provision or provisions to conflict
         with ERISA, then, upon notice thereof to the Committee, the Sponsor or
         the Trustee, as the case may be, such invalid or conflicting provisions
         of this Section shall be given no further force or effect. In such
         circumstances the Trustee shall continue to follow instructions
         received from Participants, to the extent such instructions have not
         been invalidated by such order or opinion. To the extent the Trustee is
         required by such opinion or order to exercise any residual fiduciary
         responsibility with respect to voting, the Sponsor shall appoint an
         independent fiduciary who shall exercise such residual fiduciary
         responsibility as provided in paragraph (b) above and shall direct the
         Trustee as to the manner in which Company Stock held by the Trustee
         shall be voted.

         5.10 Securities Law Limitation. Neither the Committee nor the Trustee
shall be required to engage in any transaction, including without limitation,
directing the purchase or sale of Company Stock, which either determines in its
sole discretion might tend to subject itself, its members, the Plan, the
Company, or any Participant or Beneficiary to a liability under federal or state
securities laws.

         5.11 Distributions. Money and property of the Trust shall be paid out,
disbursed, or applied by the Trustee for the benefit of Participants and
Beneficiaries under the Plan in accordance with directions received by the
Trustee from the Committee. Upon direction of the Committee, the Trustee may pay
money or deliver property from the Trust for any purpose authorized under the
Plan. The Trustee shall be fully protected in paying out money or delivering
property from the Trust from time to time upon written order of the Committee
and shall not be liable for the application of such money or property by the
Committee.

         The Trustee shall not be required to determine or to make any
investigation to determine the identity or mailing address of any person
entitled to benefits hereunder and shall have discharged its obligation in that
respect when it shall have sent checks or other property by first-class mail to
such persons at their respective addresses as may be certified to it by the
Committee.

         5.12 Taxes. If the whole or any part of the Trust, or the proceeds
thereof, shall become liable for the payment of any estate, inheritance, income
or other tax, charge, or assessment

                                       34

which the Trustee shall be required to pay, the Trustee shall have full power
and authority to pay such tax, charge, or assessment out of any moneys or other
property in its hands for the account of the person whose interests hereunder
are so liable, but at least ten (10) days prior to making any such payment, the
Trustee shall mail notice to the Committee of its intention to make such
payment. Prior to making any transfers or distributions of any of the Trust, the
Trustee may require such releases or other documents from any lawful taxing
authority as it shall deem necessary.

         5.13 Trustee Records to be Maintained. The Trustee shall keep accurate
and detailed accounts of all investments, receipts, disbursements, and other
transactions hereunder, and all accounts, books, and records relating thereto
shall be open to inspection and audit at all reasonable times by any person
designated by the Company (subject to the provisions of Section 5.8(k)).

         5.14 Annual Report of Trustee. Promptly following the close of each
Plan Year (or such other period as may be agreed upon between the Trustee and
Committee), or promptly after receipt of a written request from the Company, the
Trustee shall prepare for the Company a written account which will enable the
Company to satisfy the annual financial reporting requirements of ERISA, and
which will set forth among other things all investments, receipts,
disbursements, and other transactions effected by the Trustee during such Plan
Year or during the period from the close of the last Plan Year to the date of
such request. Such account shall also describe all securities and other
investments purchased and sold during the period to which it refers, the cost of
acquisition or net proceeds of sale, the securities and investments held as of
the date of such account, and the cost of each item thereof as carried on the
books of the Trustee. All accounts so filed shall be open to inspection during
business hours by the Company, the Committee, and by Participants and
Beneficiaries of the Plan (subject to the provisions of Section 5.8(k)).

         5.15 Appointment of Investment Manager. From time to time the
Committee, in accordance with Section 9.6 hereof, may appoint one or more
Investment Managers who shall have investment management and control over assets
of the Trust not invested or to be invested in Company Stock. The Committee
shall notify the Trustee of such assets of the appointment of the Investment
Manager. In the event more than one Investment Manager is appointed, the
Committee shall determine which assets shall be subject to management and
control by each Investment Manager and shall also determine the proportion in
which funds withdrawn or disbursed shall be charged against the assets subject
to each Investment Manager's management and control. As shall be provided in any
contract between an Investment Manager and the Committee, such Investment
Manager shall hold a revocable proxy with respect to all securities which are
held under the management of such Investment Manager pursuant to such contract
(except for Company Stock), and such Investment Manager shall report the voting
of all securities subject to such proxy on an annual basis to the Committee.

                                   ARTICLE VI
                            ACCOUNTS AND ALLOCATIONS

         6.1 Participants' Accounts. In order to account for the allocated
interest of each Participant in the Trust Fund, there shall be established and
maintained for each Participant (making such form of contribution) a Before Tax
Deposits Account, an After Tax Deposits Account, a Company Contribution Account,
and a Rollover Account.

         6.2 Allocation of Amounts Contributed by Participants. All After Tax
Deposits and Before Tax Deposits contributed by a Participant shall be allocated
to the separate Account established and maintained for that Participant for such
form of contributions. Such contributions shall be paid by the Company to the
Trustee as soon as the amount can reasonably be identified and separated from
the Company's other assets, but in any event no later than the 15th business day
of the month following the month in which such amounts would otherwise be
payable to the Participant, or such other time provided in applicable
regulations under the Code or ERISA.

         6.3 Allocation of Company Contributions and Forfeitures. Company
Contributions and Forfeitures shall be allocated as follows:

             (a) Forfeitures shall first be used to restore the Accounts of
         rehired Participants if so required under Section 8.7(c) and shall then
         be allocated to the Company Contribution Accounts of Participants to
         the extent necessary to correct insufficient allocations made to such
         Accounts in prior months discovered during the Plan Year to which such
         Forfeitures are attributable. Any remaining Forfeitures may be applied
         towards plan expenses if so directed by the Committee as provided in
         Section 9.12 or shall be used to reduce contributions made by the
         Company pursuant to Section 5.3.

             (b) Matching Contributions shall be allocated to the Company
         Contribution Accounts of all Participants who made Matched Deposits at
         such times and in such amounts as provided in Sections 5.3(a) and
         5.3(b).

             (c) Any other Company Contributions shall be used to restore the
         Accounts of rehired Participants if so required under Section 8.7(c)
         and to the extent Forfeitures are unavailable. Any amounts remaining
         may be used to pay Plan expenses if so directed by the Committee as
         provided in Section 9.12.

         The allocations of Company Contributions under this Section 6.3 shall
  be made only after any allocations required by Sections 6.8 and 13.4 have been
  made.

         6.4 Valuation of Participants' Accounts. Within sixty (60) days after
each Valuation Date the Trustee shall value the assets of the Trust on the basis
of fair market values. Company Stock held by the Trust shall be valued in
accordance with Section 6.5. If separate investment funds are maintained under
the Trust pursuant to Section 5.5(b) then each such fund shall be valued
separately so that gains or losses of the various funds shall not be commingled.
Upon

                                       36

<PAGE>   43

receipt of these valuations from the Trustee, the Committee shall revalue the
Accounts and subaccounts (as established pursuant to Section 5.5(b)), if any, of
each Participant as of the applicable Valuation Date so as to reflect, among
other things, a proportionate share in any increase or decrease in the fair
market value of the assets in the Trust Fund, determined by the Trustee as of
that date as compared with the value of the assets in the Trust Fund as of the
immediately preceding Valuation Date.

         6.5 Valuation of Company Stock. Company Stock held by the Trust shall
be valued according to the following rules:

             (a) In the case of Company Stock that is publicly traded on a
         national securities exchange, such stock shall be valued by reference
         to the closing price of such stock on such exchange on the last trading
         day of the month for which such stock is being valued.

             (b) In the case of Company Stock that is not publicly traded on a
         national securities exchange, such stock shall be valued as of the
         first day of each Plan Year, or such other time as established by the
         Committee, by determining the fair market value of such stock through
         the use of an independent appraiser. Such fair market valuation shall
         be used to determine the valuation of each Participant's Company Stock
         Account on each Valuation Date in such Plan Year pursuant to Section
         6.4.

         6.6 Dividends, Splits, Recapitalizations, Etc. Any Company Stock
received by the Trustee as a stock split, dividend, or as a result of a
reorganization or other recapitalization of the Company shall be allocated in
the same manner as the Company Stock to which it is attributable is then
allocated.

         6.7 Stock Rights, Warrants or Options.

             (a) In the event any rights, warrants, or options are issued on
         Company Stock held in the Trust Fund, the Trustee shall exercise them
         for the acquisition of additional Company Stock as directed by the
         Committee to the extent that cash is then available in the Trust Fund.

             (b) Any Company Stock acquired in this fashion shall be treated as
         Company Stock purchased by the Trustee for the net price paid and shall
         be allocated in the same manner as the funds used to purchase the
         Company Stock were or would be allocated under the provisions of the
         Plan. Thus, if the funds used to purchase the stock consisted of
         unallocated Company Contributions, the stock would be allocated under
         the terms of Section 6.3; if the funds used consisted of the
         unallocated net income of the Trust, the stock would be allocated as
         provided in Section 6.4; and if the funds used consisted of funds
         previously allocated to the Accounts, the stock would be allocated in
         the manner in which the Accounts or subaccounts are debited and
         credited.

             (c) Any rights, warrants, or options on Company Stock which cannot
         be exercised for lack of cash may, as directed by the Committee, be
         sold by the Trustee and

                                       37

<PAGE>   44

         the proceeds allocated in accordance with the source of the Company
         Stock with respect to which the rights, warrants, or options were
         issued in accordance with rules of paragraph (b) above.

         6.8 Treatment of Accounts Upon Severance. Upon a Participant's
Severance, pending distribution of the Participant's benefit pursuant to the
provisions of Article VIII, the Participant's Accounts shall continue to be
maintained and accounted for in accordance with all applicable provisions of the
Plan, including but not limited to the allocation of Company Contributions and
net income or loss to which the Accounts are entitled under the applicable
provisions of Sections 6.3 and 6.4 as of any Valuation Date or other date
preceding the distribution of the Participant's entire benefit under the Plan.

         6.9 Cash Dividends.

             (a) All cash dividends paid to the Trustee with respect to Company
         Stock that has been allocated to a Participant's Account as of the
         quarterly date on which the dividend is received by the Trustee shall
         be allocated to the Participant's Account.

             (b) If a Participant (or Beneficiary) has a current right to a
         distribution in Company Stock pursuant to Article VIII and such stock
         has not yet been re-registered in the name of the Participants (or
         Beneficiary) as of the record date of any dividend on such stock, such
         dividend shall be distributed to the Participant (or Beneficiary).

             (c) Notwithstanding the provisions of paragraphs (a) and (b) above,
         the Committee may determine, in its discretion, that cash dividends on
         such shares may be used to purchase additional shares of Company Stock,
         or in whatever other manner it deems appropriate.

         6.10 Miscellaneous Allocation Rules.

             (a) In the event that there is more than one class of Company Stock
         to be allocated to Participants' Accounts, there shall be allocated to
         the Account of each Participant (entitled to share in allocations of
         Company Stock as of any applicable date) the portion of each class of
         Company Stock (to be allocated as of that date) which the amount to be
         allocated to the Account of the Participant bears to the total amount
         to be allocated to the Accounts of all Participants entitled to share
         in such allocation.

             (b) Allocations of all assets other than Company Stock shall be
         made on the basis of, and expressed in terms of dollar value.
         Allocations of Company Stock shall be on the basis of the number of
         shares of Company Stock (including fractional shares) and valuations,
         as of each Valuation Date, shall be expressed in terms of number of
         shares and dollar value.

             (c) The Committee and the Trustee shall establish such additional
         accounting procedures as may be necessary for the purpose of making the
         allocations, valuations, withdrawals, and adjustments to Participants'
         Accounts provided for in this Article VI.

                                       38

<PAGE>   45

         From time to time the Committee and Trustee may modify such additional
         accounting procedures for the purpose of achieving equitable,
         nondiscriminatory, and administratively feasible allocations among the
         Accounts of Participants in accordance with the general concepts of the
         Plan and the provisions of this Article VI.

              (d) The Company, the Committee and Trustee do not in any manner or
         to any extent whatsoever warrant, guarantee or represent that the value
         of a Participant's Account shall at any time equal or exceed the amount
         previously contributed thereto.

         6.11 Limitations on After Tax Deposits and Company Contributions. With
respect to each Plan Year, After Tax Deposits and Matching Contributions under
the Plan for the Plan Year shall not exceed the limitations by or on behalf of
Highly Compensated Participants under Code Section 401(m), as provided in this
Section. In the event that After Tax Deposits and Matching Contributions under
the Plan by or on behalf of Highly Compensated Participants for any Plan Year
exceed the limitations of this Section for any reason, such excess After Tax
Deposits and Matching Contributions and any income or loss allocable thereto
shall be disposed of in accordance with Section 6.12.

              (a) The After Tax Deposits by Participants and Matching
         Contributions on behalf of Participants for a Plan Year shall satisfy
         the Average Contribution Percentage test set forth in (i) below, or, to
         the extent not precluded by applicable regulations, the alternative
         Average Contribution Percentage test set forth in (ii) below:

                  (i) The Average Contribution Percentage of Highly Compensated
              Participants for the Plan Year shall not be more than the prior
              Plan Year's Average Contribution Percentage of Participants who
              were not Highly Compensated Employees for the prior Plan Year
              multiplied by 1.25, or

                  (ii) The Average Contribution Percentage of Highly Compensated
              Participants for the Plan Year shall not be more than the prior
              Plan Year's Average Contribution Percentage of Participants who
              were not Highly Compensated Employees for the prior Plan Year
              multiplied by 2.0, provided that the Average Contribution
              Percentage of Highly Compensated Participants does not exceed the
              Average Contribution Percentage of Participants who were not
              Highly Compensated Employees for the prior Plan Year by more than
              two (2) percentage points (or such lesser percentage as the
              Secretary of the Treasury shall prescribe to prevent the multiple
              use of the alternative limitation set forth in this Section
              4.3(a)(ii) with respect to any Highly Compensated Participants).

                  (iii) If one or more Highly Compensated Employees participate
              in both a cash or deferred arrangement and a plan subject to the
              Average Contribution Percentage test maintained by the Sponsor or
              an Affiliated Company and the sum of the Actual Deferral
              Percentage and Contribution Percentage of those Highly Compensated
              Employees subject to either or both test exceeds the Aggregate
              Limit, then the Contribution Percentages of those Highly
              Compensated Employees who also participate in the cash or deferred
              arrangement will be

                                       39

<PAGE>   46

              reduced (beginning with such Highly Compensated Employee whose
              Average Contribution Percentage is the highest) so that the limit
              is not exceeded. The amount by which each Highly Compensated
              Employee's Contribution Percentage is reduced shall be treated as
              an Excess Aggregate Contribution. The Actual Deferral Percentage
              and Contribution Percentage of the Highly Compensated Employee are
              determined after any corrections required to meet the Actual
              Deferral Percentage and Average Contribution Percentage tests and
              are deemed to be the maximum permitted under such tests for the
              Plan Year. Multiple use does not occur if both the average Actual
              Deferral Percentage and Average Contribution Percentage of those
              Highly Compensated Employees does not exceed 125 percent of the
              Actual Deferral Percentage and Average Contribution Percentage of
              all other Participants.

              (b) For purposes of this Section 6.11 and Section 6.12 the
         following definitions shall apply:

                  (i) "Average Contribution Percentage" shall mean the average
              of the Contribution Percentages, with respect to the group of
              Highly Compensated Participants and the group of all other
              Participants for a Plan Year. The "Contribution Percentage" for
              any Participant shall mean the ratio, calculated separately and to
              the nearest one-hundredth of one percent for each Participant in
              such group, determined as follows:

                      (1) For a Highly Compensated Participant, the ratio of
                  such Participant's After Tax Deposits and Matching
                  Contributions for the current Plan Year to such Participant's
                  Compensation for the current Plan Year; provided, however,
                  that the Contribution Percentage of a Highly Compensated
                  Participant with no After Tax Deposits and Matching
                  Contributions made on his or her behalf shall be zero.

                     (2) For any other Participant, the ratio of such
                  Participant's After Tax Deposits and Matching Contributions
                  for the preceding Plan Year to such Participant's Compensation
                  for the preceding Plan Year; provided, however, that the
                  Contribution Percentage of a Participant with no After Tax
                  Deposits and Matching Contributions made on his or her behalf
                  shall be zero.

                  The Contribution Percentage, in each case, however, shall not
              include Matching Contributions that are forfeited either to
              correct Excess Aggregate Contributions or because the contribution
              to which they relate are excess Before Tax Deposits, excess After
              Tax Deposits, or Excess Aggregate Contributions. To the extent
              determined by the Committee and in accordance with regulations
              issued by the Secretary of the Treasury under Code Section
              401(m)(3), Before Tax Deposits and any qualified nonelective
              contributions, within the meaning of Code Section 401(m)(4)(C) on
              behalf of a Participant may also be taken into account for
              purposes of calculating the Contribution Percentage of a
              Participant.

                                       40

<PAGE>   47

              However, if any Before Tax Deposits are taken into account for
              purposes of determining Actual Deferral Percentages under Section
              4.3 then such Before Tax Deposits shall not be taken into account
              under this Section 6.11.

                  (ii) "Highly Compensated Participant" shall mean for any Plan
              Year any Participant who is a Highly Compensated Employee. A
              Participant is a Highly Compensated Employee for a particular Plan
              Year if he or she meets the definition of a Highly Compensated
              Employee in effect for that Plan Year. Similarly, a Participant is
              not a Highly Compensated Employee for a particular Plan Year if he
              or she does not meet the definition of a Highly Compensated
              Employee in effect for that Plan Year.

                  (iii) "Participant" shall mean any Eligible Employee who
              satisfied the requirements under Article III during the Plan Year
              whether or not such Eligible Employee has elected to contribute to
              the Plan for such Plan Year.

                  (iv) "Compensation" shall mean compensation as described
              below:

                       (1) Compensation means compensation determined by the
                  Company in accordance with the requirements of Code Section
                  414(s) and the regulations thereunder.

                       (2) For purposes of this Section 6.11, Compensation may,
                  at the Company's election, exclude amounts which are
                  excludable from a Participant's gross income under Code
                  Section 125 (pertaining to cafeteria plans) and Code Section
                  402(e)(3) (pertaining to 401(k) salary reductions). The
                  Company may change its election provided such change does not
                  discriminate in favor of Highly Compensated Employees.

                       (3) Compensation taken into account for any Plan Year
                  shall not exceed $150,000 as adjusted at the time and in such
                  manner as permitted under Code Section 401(a)(17)(B).

                  (v) "Aggregate Limit" shall mean the sum of (1) 125 percent of
              the greater of the average Actual Deferral Percentage of all
              Non-Highly Compensated Participants for the Plan Year or the
              Average Contribution Percentage of Non-Highly Compensated
              Participants under the Plan subject to Code Section 401(m) for the
              Plan Year beginning with or within the Plan Year of the cash or
              deferred arrangement and (2) the lesser of 200% or two plus the
              lesser of such average Actual Deferral Percentage or Average
              Contribution Percentage. "Lesser" is substituted for "greater" in
              (1) above, and "greater" is substituted for "lesser" after "two
              plus the" in (2) above if it would result in a larger Aggregate
              Limit.

                  (vi) "Excess Aggregate Contributions" shall mean, with respect
              to any Plan Year, the excess of:

                                       41

<PAGE>   48

                       (1) The aggregate After Tax Deposits and Matching
                  Contributions taken into account in computing the numerator of
                  the Contribution Percentage actually made on behalf of Highly
                  Compensated Employees for such Plan year, over

                       (2) The maximum After Tax Deposits and Matching
                  Contributions permitted under the Average Contribution
                  Percentage test as determined by reducing such Matching
                  Contributions made on behalf of Highly Compensated Employees
                  in order of their Contribution Percentages, beginning with the
                  highest of such percentages.

                  Such determination shall be made after first determining
              excess Before Tax Deposits pursuant to Sections 4.2(a) and 4.3.

              (c) In the event the Plan satisfies the requirements of Code
         Sections 401(m), 401(a)(4) or 410(b) only if aggregated with one or
         more other plans which include arrangements under Code Section 401(k),
         then this Section 6.11 shall be applied by determining the Contribution
         Percentages of Participants as if all such plans were a single plan.
         Any adjustments to the Contribution Percentages of Participants who are
         not Highly Compensated Employees for the prior year shall be made in
         accordance with Notice 98-1 and any superseding guidance. Plans may be
         aggregated in order to satisfy Code Section 401(m) only if they have
         the same Plan Year and use the same Average Contribution Percentage
         testing method.

              (d) For purposes of this Section 6.11, the Contribution Percentage
         for any Highly Compensated Participants who is eligible to have After
         Tax Deposits or Matching Contributions allocated to his or her account
         under two or more plans maintained by the Sponsor or an Affiliated
         Company shall be determined as if the total of such After Tax Deposits
         or Matching Contributions was made under each plan. If a Highly
         Compensated Employee participates in two or more cash or deferred
         arrangements that have different plan years, all cash or deferred
         arrangements that have different plan years, all cash or deferred
         arrangements ending with or within the same calendar year shall be
         treated as a single arrangement. Notwithstanding the foregoing, certain
         plans shall be treated as separate plans if mandatorily disaggregated
         pursuant to regulations under Code Section 401(m).

              (e) For purposes of the Average Contribution Percentage test,
         After Tax Deposits shall be considered to have been made in the Plan
         Year in which contributed to the Trust. Matching Contributions shall be
         considered made for a Plan Year if made no later than the end of the
         twelve-month period beginning on the day after the close of the Plan
         Year.

              (f) The determination and treatment of the Contribution Percentage
         of any Participant shall satisfy such other requirements as may be
         prescribed by the Secretary of the Treasury.

              (g) The Committee shall keep or cause to have kept such records as
         are necessary to demonstrate that the Plan satisfies the requirements
         of Code Section 401(m) and the regulations thereunder, in accordance
         with regulations prescribed by the Secretary of the Treasury.

         6.12 Provision for Disposition of Excess After Tax Deposits or Matching
Contributions on Behalf of Highly Compensated Participants. After application of
the provisions of Section 4.4 and 4.5, the following provisions shall be
implemented:

              (a) The Committee shall determine, as soon as is reasonably
         possible following the close of each Plan Year, the extent (if any) to
         which contributions by or on behalf of Highly Compensated Participants
         may cause the Plan to exceed the limitations of Section 6.11 for such
         Plan Year. If, pursuant to the determination by the Committee and as
         required by the leveling method described in paragraph (b) below,
         contributions by or on behalf of a Highly Compensated Participant may
         cause the Plan to exceed such limitations, then the Committee shall
         take the following steps:

                  (i) First, any excess After Tax Deposits that were not matched
              by Matching Contributions, together with income or loss allocable
              to such amount (determined in accordance with (d) below) shall be
              returned to the Highly Compensated Participant.

                  (ii) Second, if any excess remains after the provisions of (i)
              above are applied, to the extent necessary to eliminate the
              excess, Matching Contributions with respect to the Highly
              Compensated Participant, any corresponding matched After Tax
              Deposits, and any income or loss allocable thereto, shall either
              be distributed (if non-forfeitable) to the Highly Compensated
              Participant or forfeited (to the extent forfeitable under the
              Plan) on a pro-rata basis. Amounts of excess Matching
              Contributions forfeited by Highly Compensated Participants under
              this Section 6.12, including any income or loss allocable thereto,
              shall be applied to reduce Matching Contributions by the Company
              or the Affiliated Company that made the Matching Contribution on
              behalf of the Highly Compensated Participant for the Plan Year for
              which the excess contribution was made.

                  (iii) If administratively feasible, any amounts distributed
              pursuant to subparagraphs (i) or (ii) above shall be returned
              within two and one-half (2-1/2) months following the close of the
              Plan Year for which such excess After Tax Deposits or Matching
              Contributions were made, but in any event no later than the end of
              the first Plan Year following the Plan Year for which the excess
              After Tax Deposits or Matching Contributions were made. After Tax
              Deposits and Matching Contributions for any Plan Year shall be
              made on the basis of the respective portions of such excess After
              Tax Deposits and Matching Contributions attributable to each
              Highly Compensated Participant.

              (b) For purposes of satisfying the Average Contribution Percentage
         test, the amount of any excess After Tax Deposits or Matching
         Contributions by or on behalf of

                                       43

<PAGE>   50

         Highly Compensated Participants for a Plan Year under Section 6.11
         shall be determined by application of a leveling method under which the
         After Tax Deposits or Matching Contributions of the Highly Compensated
         Participant who has the highest dollar amount of After Tax Deposits or
         Matching Contributions for such Plan Year is reduced to the extent
         required to cause such Highly Compensated Participant's After Tax
         Deposits and Matching Contributions to equal the After Tax Deposits and
         Matching Contributions of the Highly Compensated Participant with the
         next highest After Tax Deposits and Matching Contributions; provided,
         however, if a lesser amount, when added to the total dollar amount
         already distributed under this paragraph (b), equals the total excess
         After Tax Deposits and Matching Contributions that are required to be
         distributed to enable the Plan to satisfy the Average Contribution
         Percentage test, the lesser amount shall be distributed. This process
         shall be repeated until the Plan satisfies the Average Contribution
         Percentage test.

              (c) The amount of income or loss attributable to any excess After
         Tax Deposits or Matching Contributions, as determined under this
         Section 6.12 (the "Excess Aggregate Contribution") by a Highly
         Compensated Participant for a Plan Year shall be equal to the sum of
         the following:

                  (i) The income or loss allocable to the Highly Compensated
              Participant's Excess Aggregate Contribution Accounts for the Plan
              Year multiplied by a fraction, the numerator of which is the
              Excess Aggregate Contribution and the denominator of which is the
              sum of the balance of the Highly Compensated Participant's Excess
              Aggregate Contribution Accounts without regard to any income or
              loss allocable to such Accounts during the Plan Year; and

                  (ii) The amount of allocable income or loss for the Gap Period
              using the "safe harbor" method set forth in regulations prescribed
              by the Secretary of the Treasury under Code Section 401(m). Under
              the "safe harbor" method, such allocable income or loss is equal
              to 10% of the amount calculated under Section 6.12(c)(i) above,
              multiplied by the number of calendar months from the last day of
              the Plan Year until the date of distribution of the Participant's
              excess After Tax Deposits or Matching Contributions. A
              distribution on or before the 15th of the month is treated as made
              on the last day of the preceding month, a distribution after the
              15th of the month is treated as made on the first day of the next
              month.

              (d) For the purpose of this Section 6.12, the following shall
         apply:

                  (i) "Excess Aggregate Contribution Accounts" shall mean the
              Participant's After Tax Deposits Account and Company Contribution
              Account.

                  (ii) "Gap Period" shall mean the period between last day of
              the Plan Year and the date of distribution of any Excess Aggregate
              Contributions.

                                       44

<PAGE>   51

              (e) Any excess After Tax Deposits and/or Matching Contributions
         distributed to a Highly Compensated Participant or forfeited by a
         Highly Compensated Participant in accordance with this Section 6.12,
         shall be treated as Annual Additions under Article XIII for the Plan
         Year for which the excess contribution was made.

              (f) Neither the Committee nor the Company shall be liable to any
         Participant (or his or her Beneficiary, if applicable) for any losses
         caused by a mistake in calculating the amount of any Excess Aggregate
         Contributions by or on behalf of a Highly Compensated Participant and
         the income or loss allocable thereto.

                            VESTING IN PLAN ACCOUNTS

         7.1 No Vested Rights Except as Herein Provided. No Participant shall
have any vested right or interest to, or any right of payment of, any assets of
the Trust Fund, except as expressly provided in the Plan. Neither the making of
any allocations nor the credit to any Account of a Participant shall vest in any
Participant any right, title, or interest in or to any assets of the Trust Fund.

         7.2 Vesting Schedule.

             (a) A Participant's interest in his or her Company Contribution
         Account shall vest in accordance with the following schedule:

              -------------------------                   -----------------
              Less than 3                                        0%
              3 or more                                        100%

              (b) Notwithstanding the above, a Participant shall become fully
         vested in his or her Company Contribution Account upon the occurrence
         of any of the following events, if such Participant is then still an
         Employee:

                  (i) Attainment of age sixty-two (62);

                  (ii) Death;

                  (iii) Severance due to a Disability; or

                  (iv) Occurrence of a Change in Control pursuant to Section
              12.4.

              (c) Notwithstanding the above, a Participant shall at all times be
         100% vested in all amounts transferred from the SmithKline Beckman
         Corporation Savings and Investment Plan to the Plan.

         7.3 Vesting of Participant Deposits. A Participant shall be fully
vested at all times in the amounts allocated to his or her Before Tax Deposits

                            PAYMENT OF PLAN BENEFITS

         8.1 Withdrawals During Employment. A Participant may withdraw, once in
any calendar quarter, amounts of at least $500 from his or her Accounts while an
Employee in accordance with the following rules:

              (a) A Participant may, for any reason, withdraw any portion of the
         amount allocated to his or her After Tax Deposit Account (excluding any
         After Tax Deposits recharacterized as such under Section 4.5). A
         Participant who makes a withdrawal of After Tax Deposits which are also
         Matched Deposits prior to July 1, 2000 shall not receive any Matching
         Contributions pursuant to Section 5.3(a) with respect to any Matched
         Deposits made by such Participant during the six (6) month period
         beginning on the date of any such withdrawal unless the After Tax
         Deposits can also be withdrawn under paragraph (d) below. A Participant
         who makes a withdrawal of After Tax Deposits (whether Matched Deposits
         or non-Matched Deposits) on or after July 1, 2000 shall not be
         permitted to make any After Tax or and Before Tax Deposits during the
         six (6) month period beginning as soon as administratively feasible
         following the date of the withdrawal unless the After Tax Deposits can
         also be withdrawn under paragraph (d) below or the withdrawal is
         comprised solely of After Tax Deposits which are not Matched Deposits
         and which were contributed prior to July 1, 2000.

              (b) A Participant may, for any reason, withdraw any portion of the
         amount allocated to his or her Rollover Account.

              (c) After withdrawing all After Tax Deposits pursuant to paragraph
         (a) and all amounts allocated to his or her Rollover Account under
         paragraph (b) above, a Participant with 3 or more years of Credited
         Service may, for any reason, withdraw any portion of the amount
         allocated to his or her Company Contribution Account that was so
         allocated 2 or more years prior to the date of such a withdrawal.

              (d) On or after the attainment of age 59-1/2, a Participant may
         withdraw any vested portion of the amounts allocated to any of his or
         her Accounts.

              (e) After withdrawing all amounts permitted pursuant to paragraphs
         (a), (b) (c), and (d) above, a Participant may withdraw amounts from
         his or her Before Tax Deposits Account (excluding any earnings
         attributable to such Account after December 31, 1988) and the vested
         portion of his or her Company Contribution Account, and any remaining
         amount in his or her After Tax Deposits (amounts which were
         recharacterized as After Tax Deposits under Section 4.5 but excluding
         any earnings attributable to recharacterized After Tax Deposits after
         December 31, 1988) upon incurring a hardship as defined in Section 8.5.

              (f) Except as provided in Section 8.5(c), all withdrawals shall be
         made in cash, except to the extent any of the vested portion of a
         Participant's Account to be

                                       47

<PAGE>   54

         withdrawn is invested in the Company Stock Fund, then such withdrawal
         may be made in Company Stock at the election of the Participant to the
         extent so invested.

              (g) Except as provided in paragraphs (a) through (e) above,
         Participants may not receive a distribution of their benefits under the
         Plan prior to termination of employment.

              (h) Except as provided in Section 8.5(c), all withdrawals shall be
         made to Participants as soon as reasonably practicable following the
         Valuation Date in the month for which a properly completed withdrawal
         request is deemed perfected. All withdrawals shall be based on the
         Account balances of a Participant as of such Valuation Date. If a
         properly completed withdrawal request is received by the Plan
         Administrator during any month and on or before the fifteenth day of
         such month, the withdrawal request shall be deemed perfected in such
         month, otherwise such withdrawal request shall be deemed perfected in
         the immediately following month.

              (i) Notwithstanding anything to the contrary in this Section 8.1
         or Section 4.1, the additional withdrawal restrictions stated in
         Section 5.5(h) shall apply to all Participants who are Insiders, as
         that term is defined Section 5.5(h).

         8.2 Distributions Upon Termination of Employment or Disability.

             (a) Subject to the provisions of Section 8.6, if a Participant
         incurs a Severance for any reason (including Disability) other than
         death, all or a portion of such Participant's entire vested portion of
         his or her Accounts under the Plan shall be (i) distributed directly to
         such Participant or (ii) at the election of the Participant,
         distributed as an Eligible Rollover Distribution and paid directly by
         the Trustee to the trustee of an Eligible Retirement Plan.

             (b) Any distribution made pursuant to paragraph (a) shall be paid
         no more than once in any calendar quarter in amounts of at least $500
         (or the Participant's entire vested portion of his or her Accounts
         under the Plan if lesser) and shall be made in cash except to the
         extent any of the vested portion of such Participant's Accounts is
         invested in the Company Stock Fund, then, to the extent so invested,
         such distribution may be made in Company Stock at the election of the
         Participant.

             (c) Notwithstanding the provisions contained in the foregoing
         paragraphs of this Section 8.2 or Section 8.1, any provision which
         restricts or would deny a Participant through the withholding of
         consent or the exercise of discretion by some person or persons other
         than the Participant (and where relevant, other than the Participant's
         spouse) of an alternative form of benefit, in violation of Code Section
         411(d)(6) and the regulation promulgated thereunder, is hereby amended
         by the deletion of the consent and/or discretion requirement.

             (d) Notwithstanding the provisions contained in the foregoing
         paragraphs of this Section 8.2 or Section 8.1, upon receipt of a
         Qualified Domestic Relations Order, the

                                       48

<PAGE>   55

         amount payable to an Alternate Payee (as such terms are described in
         Section 15.2) may be distributed to the Alternate Payee as soon as
         administratively feasible.

         8.3 Distribution Upon Death of Participant. In the event of the death
of a Participant, the Participant's benefit under the Plan shall be distributed
to the surviving spouse as Beneficiary (if still alive) unless the Participant
designated another Beneficiary pursuant to Section 8.4. If the Beneficiary is
the surviving spouse of the Participant, he or she may elect to have an Eligible
Rollover Distribution paid directly by the Trustee to the trustee of an Eligible
Retirement Plan. Distributions to the Beneficiary pursuant to this Section 8.3
shall be in the same form as specified in Section 8.2(b) above, as elected by
the Beneficiary. All such distributions shall be made as soon as practicable
after the death of the Participant. A Beneficiary may not elect to defer such a
distribution.

         8.4 Designation of Beneficiary. At any time, and from time to time,
each Participant shall have the unrestricted right to designate the Beneficiary
to receive the portion of his or her death benefit and to revoke any such
designation subject to paragraphs (a) and (b) below. Each such designation shall
be evidenced by a written instrument signed by the Participant and filed with
the Committee.

              (a) If the Participant is married and designates a Beneficiary
         other than his or her spouse, said designation shall not be honored by
         the Committee unless accompanied by the written consent of said spouse
         to said designation. Such consent (i) must designate a Beneficiary
         which may not be changed without the consent of the spouse (or the
         consent of the spouse expressly permits designation by the Participant
         without any further consent by the spouse), (ii) must acknowledge the
         effect of the designation, and (iii) must be witnessed by a Plan
         representative or a notary public. No consent of such spouse shall be
         necessary if it is established to the satisfaction of a Plan
         representative that the consent required under this paragraph (b)
         cannot or need not be obtained because (i) there is no spouse, (ii) the
         spouse cannot be located, or (iii) there exist such other circumstances
         which, pursuant to regulations under Code Section 417, permit a
         distribution to another Beneficiary. Any consent of a spouse obtained
         pursuant to this paragraph (b) or any determination that the consent of
         the spouse cannot (or need not) be obtained, shall be effective only
         with respect to that spouse. If a Participant becomes married following
         his or her designation of a Beneficiary other than his or her spouse,
         such designation shall be ineffective unless the spousal consent
         requirements of this paragraph are satisfied with respect to such
         spouse (subject, however, to the provisions of Article XV regarding
         Qualified Domestic Relations Orders).

              (b) If the Participant is married and does not designate a
         Beneficiary, the Participant's spouse shall be his or her Beneficiary
         for purposes of this Section. If the deceased Participant is not
         married and shall have failed to designate a Beneficiary, or if the
         Committee shall be unable to locate the designated Beneficiary after
         reasonable efforts have been made, or if such Beneficiary shall be
         deceased, distribution of the Participant's death benefit shall be made
         by payment of the deceased Participant's entire interest in the Trust
         to his or her personal representative in a single lump-sum payment. In
         the event the deceased Participant is not a resident of California at
         the date of his or

                                       49

         her death, the Committee, in its discretion, may require the
         establishment of ancillary administration in California. If the
         Committee cannot locate a qualified personal representative of the
         deceased Participant, or if administration of the deceased
         Participant's estate is not otherwise required, the Committee, in its
         discretion, may pay the deceased Participant's interest in the Trust to
         his or her heirs at law (determined in accordance with the laws of the
         State of California as they existed at the date of the Participant's
         death).

         8.5 Hardship Withdrawal Rules. A hardship withdrawal shall be made to a
Participant only if the Committee (or its representative) determines that the
Participant has an immediate and heavy financial need and that a withdrawal from
the Plan is necessary to satisfy such need as set forth in paragraphs (a) and
(b) below.

              (a) A hardship withdrawal shall be authorized by the Committee
         only if the Committee, based upon the Participant's representation and
         such other facts as are known to the Committee, determines that the
         requested withdrawal is on the account of:

                  (i) Medical expenses described in Code Section 213(d) incurred
              by the Participant, the Participant's spouse, or any dependents of
              the Participant (as defined in Code Section 152);

                  (ii) The purchase (excluding mortgage payments) of a principal
              residence for the Participant only;

                  (iii) The payment of tuition and related educational fees for
              the next twelve (12) months of post-secondary education for the
              Participant, his or her spouse, children, or dependents;

                  (iv) The need to prevent the eviction of the Participant from
              his or her principal residence or foreclosure on the mortgage of
              the Participant's principal residence; and

                  (v) Any other situation deemed as immediate and heavy
              financial needs by the Internal Revenue Service through the
              publication of revenue rulings, notices, and other documents of
              general applicability.

              (b) A hardship withdrawal shall be authorized by the Committee
         only if the Committee, based upon the Participant's representation and
         such other facts as are known to the Committee, determines that all of
         the following conditions are or will be satisfied:

                  (i) The amount of the withdrawal is not in excess of the
              amount required to relieve the financial need (including amounts
              necessary to pay any federal, state, or local income taxes or
              penalties reasonably anticipated to result from the withdrawal).

                                       50

<PAGE>   57

                  (ii) The Participant has obtained all distributions, other
              than hardship withdrawals, and all nontaxable (at the time of the
              loan) loans from the Plan or any other plan maintained by the
              Company.

                  (iii) The Participant shall not be permitted to make Before
              Tax Deposits or After Tax Deposits for the 12-month period
              beginning as soon as administratively feasible following the date
              of the hardship withdrawal from the Plan or any other plan
              maintained by the Company.

                  (iv) The Participant shall not be permitted to make Before Tax
              Deposits during the Participant's taxable year immediately
              following the taxable year of the hardship withdrawal that is in
              excess of the applicable limit under Code Section 402(g) for such
              immediately following taxable year less the amount of such
              Participant's Before Tax Deposits for the taxable year in which
              such Participant made the hardship withdrawal.

              (c) Notwithstanding the provisions of Section 8.1(f), all hardship
         withdrawals shall be made in cash regardless of the fund from which
         such withdrawal is made. The Committee may, at its discretion,
         establish written procedures whereby Participants may receive an
         estimated prepayment of a hardship withdrawal based on the last
         available valuation of such Participant's Accounts with a reconciling
         adjustment made to such Participant's Accounts after current valuation
         data is available.

         8.6 Distribution Rules. Notwithstanding any other provisions of this
Article VIII of the Plan regarding distributions of Participant's Accounts, the
following additional rules shall apply to all such distributions.

             (a) In no event shall any benefits under the Plan, including
         benefits upon retirement, Severance, or Disability, be paid (or
         commence to be paid) to a Participant prior to the "Consent Date" (as
         defined herein) unless the Participant consents in writing to the
         payment (or commencement of payment) of such benefits prior to said
         Consent Date. As used herein, the term "Consent Date" shall mean the
         later of (i) the Participant's 62nd birthday, or (ii) the Participant's
         Normal Retirement Age. Notwithstanding the foregoing, the provisions of
         this paragraph shall not apply (i) following the Participant's death,
         or (ii) with respect to a lump sum distribution of the vested portion
         of a Participant's Account if the total amount of such vested portion
         does not exceed $5,000.

             (b) Unless a Participant elects otherwise pursuant to paragraph (a)
         above, distributions of the vested portion of a Participant's Accounts
         shall commence no later than the 60th day after the close of the Plan
         Year in which the latest of the following events occurs: (i) the
         Participant's Normal Retirement Age; (ii) the tenth anniversary of the
         year in which the Participant commenced participation in the Plan; or
         (iii) the termination of the Participant's employment with the Company.

                                       51

<PAGE>   58

             (c) Notwithstanding paragraphs (a) or (b) above, distributions of
         the entire vested portion of a Participant's Accounts shall be made no
         later than the Participant's Required Beginning Date, or, if such
         distribution is to be made over the life of such Participant or over
         the lives of such Participant and a Beneficiary (or over a period not
         extending beyond the life expectancy of such Participant and
         Beneficiary) then such distribution shall commence no later than the
         Participant's Required Beginning Date. Required Beginning Date shall
         mean:

                  (i) Participants attaining age 70-1/2 prior to 1999: The
             Required Beginning Date of a Participant who attains age 70-1/2
             prior to 1999 shall be April 1 of the calendar year immediately
             following the year in which the Participant attains age 70-1/2;
             provided, however, that a Participant, other than a Five Percent
             Owner (as defined in Code Section 416(i) and applicable
             regulations), who attains age 70-1/2 in 1996, 1997, or 1998 may
             elect to defer the Required Beginning Date until April 1 of the
             calendar year following the later of the calendar year in which the
             Participant attains age 70-1/2 or retires.

                  (ii) Participants attaining age 70-1/2 after 1998: The
             Required Beginning Date of a Participant who attains age 70-1/2
             after 1998 shall be April 1 of the calendar year immediately
             following the later of the calendar year in which the Participant
             attains age 70-1/2 or retires; provided, however, if such
             Participant is a Five Percent Owner (as defined in Code Section
             416(i) and applicable regulations) with respect to the Plan Year
             ending in the calendar year in which such Participant attains age
             70-1/2, the Required Beginning Date shall be April 1 of the
             calendar year immediately following the year in which such
             Participant attains age 70-1/2.

              (d) Notwithstanding anything to the contrary in the Plan, if a
         Participant dies before distribution of his or her vested benefit has
         begun in accordance with paragraph (c) above, the Participant's vested
         benefit shall be distributed to his or her Beneficiary within five
         years from the date of the Participant's death except that any portion
         of the Account balance meeting the following requirements shall not be
         subject to this rule:

                  (i) A Beneficiary has been designated to receive the
             Participant's Account balance and such designation is effective at
             the Participant's death;

                  (ii) The Account balance is paid to the Beneficiary over the
             Beneficiary's life or over a period not to exceed the Beneficiary's
             life; and

                  (iii) The payments to the Beneficiary commence within one year
             of the Participant's death, or, if the Beneficiary is the spouse,
             before the time the deceased Participant would have attained age
             70-1/2.

              (e) All distributions under the Plan shall be made in accordance
         with the minimum distribution incidental benefit requirements of Code
         Section 401(a)(9)(G) and in accordance with all regulations issued
         under Code Section 401(a)(9).

                                       52

<PAGE>   59

              (f) If it is not administratively practical to calculate and
         commence payments by the latest date specified in the rules of
         paragraphs (b), (c) and (d) above because the amount of the
         Participant's benefit cannot be calculated, or because the Committee is
         unable to locate the Participant (or eligible Beneficiary) after making
         reasonable efforts to do so, the payment shall be made as soon as is
         administratively possible (but not more than 60 days) after the
         Participant (or Beneficiary) can be located and the amount of the
         distributable benefit can be ascertained.

         8.7 Forfeitures.

              (a) In the event that a distribution of the entire vested portion
         of a Participant's Accounts is made to a Participant due to a Severance
         when he or she is not fully vested in such Accounts, the nonvested
         portion of the Participant's Account(s) shall be forfeited as of the
         Participant's Severance Date. A Participant who incurs such a Severance
         when no portion of his or her Accounts are vested shall be deemed to
         have received a distribution pursuant to this paragraph (a).

              (b) If a Participant incurs a Severance when partially vested in
         his or her Accounts and does not receive a distribution described in
         paragraph (a), the Participant's Account shall be held by the Trustee
         as provided in Section 6.8 for 90 days at which time, the nonvested
         portion of the Participant's Account(s) shall be forfeited as of the
         last day of the month in which the 90-day period ends.

              (c) In the event a Participant is rehired by the Company prior to
         the date such Participant incurs five consecutive Breaks in Service,
         the amount so forfeited pursuant to paragraphs (a) and (b) above shall
         be reinstated to the Participant as of his or her Reemployment
         Commencement Date (without regard to any interest or investment
         earnings on such amount).

              (d) Forfeitures shall be allocated in the manner provided in
         Section 6.3 at such times as determined by the Committee and to the
         extent available shall be used to reduce contributions made by the
         Company pursuant to Section 5.3.

         8.8 Valuation of Plan Benefits Upon Distribution. For the purpose of
any distribution of benefits under this Article VIII, the amount of such
distribution shall be based on the value of a Participant's Accounts as of the
Valuation Date in the month in which the application for such distribution is
deemed perfected. If a properly completed distribution application is received
by the Committee during any month and on or before the fifteenth day of such
month, the distribution application shall be deemed perfected in such month,
otherwise such distribution application shall be deemed perfected in the
immediately following month.

         8.9 Lapsed Benefits.

             (a) In the event that a benefit is payable under the Plan to a
         Participant and after reasonable efforts the Participant cannot be
         located for the purpose of paying the

                                       53

<PAGE>   60

         benefit during a period of three consecutive years, the Participant
         shall be presumed dead and the benefit shall, upon the termination of
         that three year period, be paid to the Participant's Beneficiary.

             (b) If any eligible Beneficiary cannot be located for the purpose
         of paying the benefit for the following two years, then the benefit
         shall be forfeited and allocated to the Accounts of the other
         Participants for such Plan Year in accordance with Section 6.3.

             (c) If a Participant shall die prior to receiving a distribution of
         his or her entire benefit under the Plan (other than a Participant
         presumed to have died as provided above), if after reasonable efforts
         an eligible Beneficiary of the Participant cannot be located for the
         purpose of paying the benefit during a period of five consecutive
         years, the benefit shall, upon expiration of such five-year period, be
         forfeited and reallocated to the Accounts of the other Participants in
         accordance with Section 6.3.

             (d) For purposes of this Section, the term "Beneficiary" shall
         include any person entitled under Section 8.4 to receive the interest
         of a deceased Participant or deceased designated Beneficiary. It is the
         intention of this provision that during the relevant waiting period
         (two years or five years) the benefit will be distributed to an
         eligible Beneficiary in a lower priority category under Section 8.4 if
         no eligible Beneficiary in a higher priority category can be located by
         the Committee after reasonable efforts have been made.

             (e) Notwithstanding the foregoing rules, if after such a forfeiture
         the Participant or an eligible Beneficiary shall claim the forfeited
         benefit, the amount forfeited shall be reinstated (without regard to
         any interest or investment earnings on such amount) and paid to the
         claimant as soon as practical following the claimant's production of
         reasonable proof of his or her identity and entitlement to the benefit
         (determined pursuant to the Plan's normal claim review procedures under
         Section 9.8).

             (f) The Committee shall direct the Trustee with respect to the
         procedures to be followed concerning a missing Participant (or
         Beneficiary), and the Company shall be obligated to contribute to the
         Trust Fund any amounts necessary after the application of Section 6.3
         to pay any reinstated benefit after it has been forfeited pursuant to
         the provisions of this Section.

         8.10 Persons Under Legal Disability.

             (a) If any payee under the Plan is a minor or if the Committee
         reasonably believes that any payee is legally incapable of giving a
         valid receipt and discharge for any payment due him/her, the Committee
         may have the payment, or any part thereof, made to the person (or
         persons or institution) whom it reasonably believes is caring for or
         supporting the payee, unless it has received due notice of claim
         therefor from a duly appointed guardian or committee of the payee.

                                       54

<PAGE>   61

             (b) Any such payment shall be a payment from the Accounts of the
         payee and shall, to the extent thereof, be a complete discharge of any
         liability under the Plan to the payee.

         8.11 Additional Documents.

             (a) The Committee or the Company may require satisfactory proof of
         any matter under the Plan from or with respect to any Employee,
         Participant, or Beneficiary, and no person shall be entitled to receive
         any benefits under the Plan until the required proof shall be
         furnished.

             (b) The Committee or Trustee, or both, may require the execution
         and delivery of such documents, papers and receipts as the Committee or
         Trustee may determine necessary or appropriate in order to establish
         the fact of death of the deceased Participant and of the right and
         identity of any Beneficiary or other person or persons claiming any
         benefits under this Article VIII.

             (c) The Committee or the Trustee, or both, may, as a condition
         precedent to the payment of death benefits hereunder, require an
         inheritance tax release and/or such security as the Committee or
         Trustee, or both, may deem appropriate as protection against possible
         liability for State or Federal death taxes attributable to any death
         benefits.

         8.12 Trustee-to-Trustee Transfers. In the case of any Participant or
Participants who have terminated employment with the Company and all Affiliated
Companies and subsequently become employed by an unrelated successor employer,
the Committee, shall at the request of such Participant or Participants, direct
the Trustee to transfer the assets in the Accounts of such Participant or
Participants directly to the trustee of any retirement plan maintained by such
successor employer or employers in lieu of any distribution described in the
preceding provisions of this Article VIII but only if (i) the retirement plan
maintained by such successor employer is determined to the satisfaction of the
Committee to be qualified under Code Section 401, (ii) the sponsor and trustee
of such plan consent to the transfer, and (iii) such transfer satisfies the
conditions of Section 12.3 hereof.

         8.13 Loans to Participants. A Participant may borrow from his or her
Accounts while an Employee in accordance with the following rules:

              (a) Subject to minimum and maximum loan requirements, a
         Participant may borrow up to 50% of his or her After Tax Deposits
         Account, Rollover Account, the vested portion of his or her Company
         Contribution Account and Before Tax Deposits Account. Only one loan may
         be outstanding to a Participant any time. The minimum loan amount shall
         be $1,000 and the maximum loan amount shall be $50,000. The $50,000
         maximum loan amount shall be reduced by the excess, if any, of the
         highest outstanding balance of loans from the Plan to the Participant
         during the one-year period ending on the day before the loan is made
         over the outstanding balance of loans on the date the loan is made.

                                       55

<PAGE>   62

              (b) A loan to a Participant shall be made solely from his or her
         Account(s) and shall be considered an investment directed by the
         Participant. Loan amounts shall be funded from the Participant's
         Accounts as determined under procedures established by the Committee;
         provided, however, that principal repayments shall be credited to the
         Participant's Accounts in the inverse of the order used to fund the
         loan and interest payments shall be credited to the Participant's
         Accounts in direct proportion to the principal repayments.

              (c) A loan to a Participant shall bear an interest rate equal to
         the prime rate reported in the Wall Street Journal on first business
         day of the month in which the loan is granted (the last business day of
         the previous month for loans made prior to July 1, 2000) plus one
         percent (1%) and shall remain fixed throughout the term of the loan.
         Notwithstanding the preceding sentence, if the Committee determines
         that such rate is not reasonable or otherwise not in accordance with
         applicable requirements under the Code or ERISA, the Committee shall
         set an alternate interest rate at the time that the loan is taken.

              (d) A loan to a Participant shall have a definite maturity date.
         Loans, other than loans made for the purpose of acquiring the principal
         residence of the Participant, shall be made for a period not to exceed
         five (5) years. Loans made for the purpose of acquiring the principal
         residence of the Participant shall be made for a period not to exceed
         fifteen (15) years.

              (e) A loan to a Participant shall have a definite repayment
         schedule and shall be amortized on a substantially level basis with
         repayments occurring not less frequently than quarterly.
         Notwithstanding the foregoing, the loan repayments shall be suspended
         during an unpaid Leave of Absence not to exceed one year at which time
         loan repayments shall resume. In the case of a Leave of Absence due to
         qualified military service, loan repayments shall be suspended as
         permitted under Code Section 414(u)(4).

              (f) A loan to a Participant shall be secured by the vested portion
         of the Participant's Account(s). No more than 50% of the Participant's
         vested Account(s) as determined on the date the loan is issued shall be
         considered by the Plan as security for a loan. A Participant who
         borrows from the Plan hereby agrees that, unless expressly provided
         otherwise in loan documents, any such loan is automatically secured by
         50% of his or her vested Account(s).

              (g) A loan to a Participant shall be evidenced by a promissory
         note and/or such other documentation as required by the Committee.

              (h) A loan to a Participant shall be treated as a distribution
         unless the entire principal amount and any interest accrued thereon is
         repaid within ninety (90) days after the occurrence of a Participant's
         Severance. Absent repayment by the Participant, the Committee shall
         instruct the Trustee to distribute the note to the Participant as part
         of his

                                       56

<PAGE>   63

         or her distribution and the Participant's vested Account(s) shall be
         reduced to the extent of such distribution.

              (i) The Committee shall establish the participant loan program and
         have the duty to manage and administer the participant loan program in
         accordance with the terms and provisions of this Section. The Committee
         shall have, but not by way of limitation, the following discretionary
         powers and authority:

                  (i) To determine the manner in which loan repayments shall
              occur whether it be through automatic payroll deductions or
              otherwise.

                  (ii) To determine the amount of loan repayments following
              suspension due to an unpaid Leave of Absence subject to the
              requirement that the loan must be repaid by the latest date
              permitted under paragraph (d).

                  (iii) To establish any fees, including but not limited to
              application fees and maintenance fees, and the manner in which
              such fees are collected from the Participant.

                  (iv) To consider only those factors which would be considered
              in a normal commercial setting by persons in the business of
              making similar types of loans in establishing the participant loan
              program. Such factors may include the applicant's credit
              worthiness and financial need, but may not include any factor
              which would discriminate against Participants who are not Highly
              Compensated Employees. Loans shall be made available to all
              Participants without regard to a Participant's race, color,
              religion, sex, age or national origin and shall not be made
              available to Participants who are Highly Compensated Employees in
              an amount greater than the amount made available to Participants
              who are not Highly Compensated Employees.

                          OPERATION AND ADMINISTRATION

         9.1 Appointment of Committee. There is hereby created a committee (the
"Committee") which shall exercise such powers and have such duties in
administering the Plan as are hereinafter set forth. The Board of Directors
shall determine the number of members of such Committee. The members of the
Committee shall be appointed by the Board of Directors and such Board shall from
time to time fill all vacancies occurring in said Committee. The members of the
Committee shall constitute the Named Fiduciaries of the Plan within the meaning
of Section 402(a)(2) of ERISA; provided that solely for purposes of Section 5.8
hereof, Participants shall be Named Fiduciaries with respect to shares of
Company Stock allocated to their respective Accounts and solely for purposes of
Section 5.9, Participants shall be Named Fiduciaries with respect to shares of
Company Stock allocated to their respective Accounts on matters as to which they
are entitled to provide voting directions.

         9.2 Transaction of Business. A majority of the Committee shall
constitute a quorum for the transaction of business. Actions of the Committee
may be taken either by vote at a meeting or in writing without a meeting. All
action taken by the Committee at any meeting shall be by a vote of the majority
of those present at such meeting. All action taken in writing without a meeting
shall be by a vote of the majority of those responding in writing. All notices,
advices, directions and instructions to be transmitted by the Committee shall be
in writing and signed by or in the name of the Committee. In all its
communications with the Trustee, the Committee may, by either of the majority
actions specified above, authorize any one or more of its members to execute any
document or documents on behalf of the Committee, in which event it shall notify
the Trustee in writing of such action and the name or names of its members so
designated and the Trustee shall thereafter accept and rely upon any documents
executed by such member or members as representing action by the Committee until
the Committee shall file with the Trustee a written revocation of such
designation.

         9.3 Voting. Any member of the Committee who is also a Participant
hereunder shall not be qualified to act or vote on any matter relating solely to
himself, and upon such matter his or her presence at a meeting shall not be
counted for the purpose of determining a quorum. If, at any time a member of the
Committee is not so qualified to act or vote, the qualified members of the
Committee shall be reduced below two (2), the Board of Directors shall promptly
appoint one or more special members to the Committee so that there shall be at
least one qualified member to act upon the matter in question. Such special
Committee members shall have power to act only upon the matter for which they
were especially appointed and their tenure shall cease as soon as they have
acted upon the matter for which they were especially appointed.

         9.4 Responsibility of Committee. The authority to control and manage
the operation and administration of the Plan, the general administration of the
Plan, the responsibility for carrying out the Plan and the authority and
responsibility to control and manage the assets of the Trust are hereby
delegated by the Board of Directors to and vested in the Committee, except to
the extent reserved to the Board of Directors, the Sponsor, or the Company.

establish rules for the

                                       58

performance of its functions, the Committee shall not discriminate in favor of
Highly Compensated Employees.

         9.5 Committee Powers. The Committee shall have all discretionary powers
necessary to supervise the administration of the Plan and control its
operations. In addition to any discretionary powers and authority conferred on
the Committee elsewhere in the Plan or by law, the Committee shall have, but not
by way of limitation, the following discretionary powers and authority:

             (a) To designate agents to carry out responsibilities relating to

         fiduciary may have under the Plan.

         other person whatsoever, including but not limited to all questions
         relating to eligibility to participate in the Plan, the amount of
         Credited Service of any Participant, and the amount of benefits to
         which any Participant or his or her Beneficiary may be entitled.

             (e) To determine the manner in which the assets of the Plan, or any
         part thereof, shall be disbursed.

             (f) To direct the Trustee, in writing, from time to time, to invest
         and reinvest the Trust Fund, or any part thereof, or to purchase,
         exchange, or lease any property, real or personal, which the Committee
         may designate. This shall include the right to direct the investment of
         all or any part of the Trust in any one security or any one type of
         securities permitted hereunder. Among the securities which the
         Committee may direct the Trustee to purchase are "qualifying employer

             (h) To perform or cause to be performed such further acts as it may
         deem to be necessary, appropriate or convenient in the efficient
         administration of the Plan.

                                       59

<PAGE>   66

         Any action taken in good faith by the Committee in the exercise of
discretionary powers conferred upon it by the Plan shall be conclusive and
binding upon the Participants and their Beneficiaries. All discretionary powers
conferred upon the Committee shall be absolute; provided, however, that all such
discretionary power shall be exercised in a uniform and nondiscriminatory
manner.

powers or authority conferred on the Committee elsewhere in the Plan or by law,
such Committee shall have the following discretionary powers and authority:

         invested or to be invested in Company Stock.

             (b) To designate persons (other than the members of the Committee)
         to carry out fiduciary responsibilities, other than any responsibility
         to manage or control the assets of the Trust;

             (c) To allocate fiduciary responsibilities among the members of the
         Committee, other than any responsibility to manage or control the

         any reason;

until accepted in writing by the indicated responsible person.

         9.7 Periodic Review of Funding Policy. At periodic intervals the
Committee shall review the long-run and short-run financial needs of the Plan
and shall determine a funding policy for the Plan consistent with the objectives
of the Plan and the minimum funding standards of ERISA, if applicable. In
determining such funding policy the Committee shall take into account, at a
minimum, not only the long-term investment objectives of the Trust Fund
consistent with the prudent management of the assets thereof, but also the
short-run needs of the Plan to pay benefits. All actions taken by the Committee
with respect to the funding policy of the Plan, including the reasons therefor,
shall be fully reflected in the minutes of the Committee.

         9.8 Claims Procedures. If a Participant believes that he or she is
being denied any rights or benefits under the Plan, such Participant (or his or
her beneficiary or duly appointed representative) may file a claim for benefits
in writing with the Committee. The Committee shall follow the procedures set
forth in this Section in processing a claim for benefits.

                                       60

<PAGE>   67

             (a) Within 90 days following receipt by the Committee of a claim
         for benefits and all necessary documents and information, the Committee
         shall furnish the person claiming benefits under the Plan ("Claimant")
         with written notice of the decision rendered with respect to such
         claim. Should special circumstances require an extension of time for
         processing the claim, written notice of the extension shall be
         furnished to the Claimant prior to the expiration of the initial 90 day
         period. The notice shall indicate the special circumstances requiring
         an extension of time and the date by which a final decision is expected
         to be rendered. In no event shall the period of the extension exceed 90
         days from the end of the initial 90 day period.

             (b) In the case of a denial of the Claimant's claim, the written
         notice of such denial shall set forth (i) the specific reasons for the
         denial, (ii) references to the Plan provisions upon which the denial is
         based, (iii) a description of any additional information or material
         necessary for perfection of the application (together with an
         explanation why such material or information is necessary), and (iv) an
         explanation of the Plan's appeals procedures.

             (c) If the Committee does not respond within 180 days, the Claimant
         may consider his or her claim denied.

         9.9 Appeals Procedures. A Claimant who wishes to appeal the denial of
his or her claim for benefits or to contest the amount of benefits payable shall
follow the administrative procedures for an appeal as set forth in this Section
and shall exhaust such administrative procedures prior to seeking any other form
of relief.

             (a) In order to appeal a decision rendered with respect to his or
         her claim for benefits or with respect to the amount of his or her
         benefits, a Claimant must file an appeal with the Committee in writing
         within 60 days after the date of notice of the decision with respect to
         the claim, or if the claim has neither been approved nor denied within
         the period provided in Section 9.8(a) above, then the appeal must be
         made within 60 days after the expiration of the period provided in
         Section 9.8(c).

             (b) The Claimant may request that his or her appeal be given full
         and fair review by the Committee. The Claimant also may review all
         pertinent documents and submit issues and comments in writing in
         connection with the appeal. The decision of the Committee shall be made
         not later than 60 days after the Claimant has completed his or her
         submission to the Committee of his or her appeal and any documentation
         or other information to be submitted in support of such request. Should
         special circumstances require an extension of time for processing,
         written notice of the extension shall be furnished to the Claimant
         prior to the expiration of the initial 60 day period. The notice shall
         indicate the special circumstances requiring an extension of time and
         the date by which a final decision is expected to be rendered. In no
         event shall the period of the extension exceed 60 days from the end of
         the initial 60 day period.

                                       61

<PAGE>   68

             (c) The decision on the Claimant's appeal shall be in writing and
         shall include specific reasons for the decision, written in a manner
         calculated to be understood by the Claimant with specific reference to
         the pertinent Plan provisions upon which the decision is based.

             (d) If the Committee does not respond within 120 days, the Claimant
         may consider his or her appeal denied.

         9.10 Limitation on Liability. Each of the fiduciaries under the Plan
shall be solely responsible for its own acts and omissions and no fiduciary
shall be liable for any breach of fiduciary responsibility resulting from the
act or omission of any other fiduciary or person to whom fiduciary
responsibilities have been allocated or delegated pursuant to Section 9.6,
except as provided in Sections 405(a) and 405(c)(2)(A) or (B) of ERISA. The
Committee shall have no responsibility over assets as to which management and
control has been delegated to an Investment Manager appointed pursuant to
Section 5.15 hereof or as to which management and control has been retained by
the Trustee.

         9.11 Indemnification and Insurance. To the extent permitted by law, the
Company shall indemnify and hold harmless the Committee and each member thereof,
each Trustee, the Board of Directors and each member thereof, and such other
persons as the Board of Directors may specify, from the effects and consequences
of his or her acts, omissions, and conduct in his or her official capacity in
connection with the Plan and Trust. To the extent permitted by law, the Company
may also purchase liability insurance for such persons.

         9.12 Compensation of Committee and Plan Expenses. Members of the
Committee shall serve as such without compensation unless the Board of Directors
shall otherwise determine, but in no event shall any member of the Committee who
is an Employee receive compensation from the Plan for his or her services as a
member of the Committee. All members shall be reimbursed for any necessary
expenditures incurred in the discharge of duties as members of the Committee.
The compensation or fees, as the case may be, of all officers, agents, counsel,
the Trustee or other persons retained or employed by the Committee shall be
fixed by the Committee, subject to approval by the Board of Directors. The
expenses incurred in the administration and operation of the Plan, including but
not limited to the expenses incurred by the members of the Committee in
exercising their duties, shall be paid by the Plan from the Trust Fund, unless
paid by the Company, provided, however, that the Plan and not the Company shall
bear the cost of interest and normal brokerage charges which are included in the
cost of securities purchased by the Trust Fund (or charged to proceeds in the
case of sales). If such expenses are to be paid by the Plan from the Trust Fund,
the Committee may direct the Trustee to use forfeitures and dividends (and to
sell the shares of Company Stock that represent such forfeitures or dividends)
to pay such expenses.

         9.13 Resignation. Any member of the Committee may resign by giving
fifteen (15) days notice to the Board of Directors, and any member shall resign
forthwith upon receipt of the written request of the Board of Directors, whether
or not said member is at that time the only member of the Committee.

         9.14 Reliance Upon Documents and Opinions. The members of the
Committee, the Board of Directors, the Company and any person delegated to carry
out any fiduciary responsibilities under the Plan (hereinafter a "delegated
fiduciary"), shall be entitled to rely upon any tables, valuations,
computations, estimates, certificates and reports furnished by any consultant,
or firm or corporation which employs one or more consultants, upon any opinions
furnished by legal counsel, and upon any reports furnished by the Trustee or any
Investment Manager. The members of the Committee, the Board of Directors, the
Company and any delegated fiduciary shall be fully protected and shall not be
liable in any manner whatsoever for anything done or action taken or suffered in
reliance upon any such consultant, or firm or corporation which employs one or
more consultants, Trustee, Investment Manager, or counsel. Any and all such
things done or such action taken or suffered by the Committee, the Board of
Directors, the Company and any delegated fiduciary shall be conclusive and
binding on all Employees, Participants, Beneficiaries, and any other persons
whomsoever, except as otherwise provided by law. The Committee and any delegated
fiduciary may, but are not required to, rely upon all records of the Company
with respect to any matter or thing whatsoever, and may likewise treat such
records as conclusive with respect to all Employees, Participants,
Beneficiaries, and any other persons whomsoever, except as otherwise provided by
law.

                         AMENDMENT AND ADOPTION OF PLAN

         10.1 Right to Amend Plan. The Sponsor, by resolution of the Board of
Directors, shall have the right to amend the Plan and Trust Agreement at any
time and from time to time and in such manner and to such extent as it may deem
advisable, including retroactively, subject to the following provisions:

              (a) No amendment shall have the effect of reducing any
Participant's vested interest in the Plan or eliminating an optional form of
distribution.

              (b) No amendment shall have the effect of diverting any part of
the assets of the Plan to persons or purposes other than the exclusive benefit
of the Participants or their Beneficiaries.

              (c) No amendment shall have the effect of increasing the duties or
responsibilities of a Trustee without its written consent.

              (d) No amendment shall result in discrimination in favor of
officers, shareholders, or other highly compensated or key employees.

         The Committee shall have the right to amend the Plan, subject to the
above provisions (a) through (d), in accordance with the provisions of Section
9.5(g).

         10.2 Adoption of Plan by Affiliated Companies. Subject to approval by
the Board of Directors, and consistent with the provisions of ERISA, an
Affiliated Company may adopt the Plan for all or any specified group of its
Eligible Employees by entering into an adoption agreement in the form and
substance prescribed by the Committee. The adoption agreement may include such
modification of the Plan provisions with respect to such Eligible Employees as
the Committee approves after having determined that no prohibited discrimination
or other threat to the qualification of the Plan is likely to result. The Board
of Directors may prospectively revoke or modify an Affiliated Company's
participation in the Plan at any time and for any or no reason, without regard
to the terms of the adoption agreement, or terminate the Plan with respect to
such Affiliated Company's Eligible Employees and Participants. By execution of
an adoption agreement (each of which by this reference shall become part of the
Plan), the Affiliated Company agrees to be bound by all the terms and conditions
of the Plan.

                         DISCONTINUANCE OF CONTRIBUTIONS

         In the event the Company decides it is impossible or inadvisable for
business reasons to continue to make contributions under the Plan, it may, by
resolution of the Board of Directors, discontinue contributions to the Plan.
Upon the permanent discontinuance of contributions to the Plan and
notwithstanding any other provisions of the Plan, the rights of Participants
shall become fully vested and nonforfeitable unless replaced by a comparable
plan. The permanent discontinuance of contributions on the part of the Company
shall not terminate the Plan as to the funds and assets then held in the Trust,
or operate to accelerate any payments of distributions to or for the benefit of
Participants or Beneficiaries, and the Trust shall continue to be administered
in accordance with the provisions hereof until the obligations hereunder shall
have been discharged and satisfied.

                             TERMINATION AND MERGER

         12.1 Right to Terminate Plan. In the event the Board of Directors
decides it is impossible or inadvisable for business reasons to continue the
Plan, then it may, by resolution, terminate the Plan. Upon and after the
effective date of such termination, the Company shall not make any further
contributions under the Plan. Upon the termination or partial termination of the
Plan for any reason, the interest in the Trust of each affected Participant
shall automatically become fully vested unless the Plan is continued after its
termination by conversion of the Plan into a comparable Plan through Plan
amendment or through merger. After the satisfaction of all outstanding
liabilities of the Plan to persons other than Participants and Beneficiaries,
all unallocated assets shall be allocated to the Accounts of Participants to the
maximum extent permitted by law. The Trust Fund may not be fully or finally
liquidated until all assets are allocated to Accounts; alternatively any
unallocated assets may be transferred to another defined contribution plan
maintained by the Sponsor or an Affiliated Company qualified under Code Section
401 where such assets shall be allocated among the accounts of Participants
herein who are participants in such transferee plan. In no event, however, shall
any part of the Plan revert to or be recoverable by the Company, or be used for
or diverted to purposes other than for the exclusive benefit of the Participants
or their Beneficiaries. Notwithstanding the foregoing, amounts held in the 415
Suspense Account may revert to the Company in accordance with Section 13.7.

         12.2 Merger Restriction. Notwithstanding any other provision in the
Plan, the Plan shall not in whole or in part merge or consolidate with, or
transfer its assets or liabilities to, any other plan unless each affected
Participant in the Plan would (if such other plan then terminated) receive a
benefit immediately after the merger, consolidation, or transfer which is equal
to or greater than the benefit he or she would have been entitled to receive
immediately before the merger, consolidation, or transfer (if the Plan had then
terminated).

         12.3 Effect on Trustee and Committee. The Trustee and the Committee
shall continue to function as such for such period of time as may be necessary
for the winding up of the Plan and for the making of distributions in the manner
prescribed by the Board of Directors at the time of termination of the Plan.

         12.4 Effect of Reorganization, Transfer of Assets or Change in Control.

              (a) In the event of a consolidation or merger of the Company, or
         in the event of a sale and/or any other transfer of the operating
         assets of the Company, any ultimate successor or successors to the
         business of the Company may continue the Plan in full force and effect
         by adopting the same by resolution of its board of directors and by
         executing a proper supplemental or transfer agreement with the Trustee.

              (b) In the event of a Change in Control (as herein defined), all
         Participants who were Participants on the date of such Change in
         Control shall become 100% vested in any amounts allocated to their
         Company Contribution

                                       66

<PAGE>   73

         Accounts on the date of such Change in Control and in any amounts
         allocated to their Company Contribution Accounts subsequent to the date
         of the Change in Control. Notwithstanding the foregoing, the Board of
         Directors may, at its discretion, amend or delete this paragraph (b) in
         its entirety prior to the occurrence of any such Change in Control. For
         the purpose of this paragraph (b), "Change in Control" shall mean the
         following and shall be deemed to occur if any of the following events
         occur:

                  (i) Any "person," as such term is used in Sections 13(d) and
              14(d) of the Securities Exchange Act of 1934, as amended (the
              "Exchange Act") (a "Person"), is or becomes the "beneficial
              owner," as defined in Rule 13d-3 under the Exchange Act (a
              "Beneficial Owner"), directly or indirectly, of securities of the
              Sponsor representing (1) 20% or more of the combined voting power
              of the Sponsor's then outstanding voting securities, which
              acquisition is not approved in advance of the acquisition or
              within 30 days after the acquisition by a majority of the
              Incumbent Board (as hereinafter defined) or (2) 33% or more of the
              combined voting power of the Sponsor's then outstanding voting
              securities, without regard to whether such acquisition is approved
              by the Incumbent Board;

                  (ii) Individuals who, as of the date hereof, constitute the
              Board of Directors (the "Incumbent Board"), cease for any reason
              to constitute at least a majority of the Board of Directors,
              provided that any person becoming a director subsequent to the
              date hereof whose election, or nomination for election by the
              Sponsor's stockholders, is approved by a vote of at least a
              majority of the directors then comprising the Incumbent Board
              (other than an election or nomination of an individual whose
              initial assumption of office is in connection with an actual or
              threatened election contest relating to the election of the
              directors of the Sponsor, as such terms are used in Rule 14a-11 of
              Regulation 14A promulgated under the Exchange Act) shall, for the
              purposes of this Plan, be considered as though such person were a
              member of the Incumbent Board of the Sponsor;

                  (iii) The consummation of a merger, consolidation or
              reorganization involving the Sponsor, other than one which
              satisfies both of the following conditions:

                        (1) a merger, consolidation or reorganization which
                  would result in the voting securities of the Sponsor
                  outstanding immediately prior thereto continuing to represent
                  (either by remaining outstanding or by being converted into
                  voting securities of another entity) at least 55% of the
                  combined voting power of the voting securities of the Sponsor
                  or such other entity resulting from the merger, consolidation
                  or reorganization (the "Surviving Corporation") outstanding
                  immediately after such merger, consolidation or reorganization
                  and being held in substantially the same proportion as the
                  ownership in the Sponsor's voting

                                       67

                  securities immediately before such merger, consolidation or
                  reorganization, and

                        (2) a merger, consolidation or reorganization in which
                  no Person is or becomes the Beneficial Owner, directly or
                  indirectly, of securities of the Sponsor representing 20% or
                  more of the combined voting power of the Sponsor's then
                  outstanding voting securities; or

                  (iv) The stockholders of the Sponsor approve a plan of
              complete liquidation of the Sponsor or an agreement for the sale
              or other disposition by the Sponsor of all or substantially all of
              the Sponsor's assets.

              Notwithstanding the preceding provisions of this paragraph (b), a
         Change in Control shall not be deemed to have occurred if the Person
         described in the preceding provisions of this paragraph (b) is (i) an
         underwriter or underwriting syndicate that has acquired any of the
         Sponsor's then outstanding voting securities solely in connection with
         a public offering of the Sponsor's securities, (ii) the Sponsor or any
         subsidiary of the Sponsor or (iii) an employee stock ownership plan or
         other employee benefit plan maintained by the Sponsor or an Affiliated
         Company that is qualified under the provisions of the Code. In
         addition, notwithstanding the preceding provisions of this paragraph
         (b), a Change in Control shall not be deemed to have occurred if the
         Person described in the preceding provisions of this paragraph (b)
         becomes a Beneficial Owner of more than the permitted amount of
         outstanding securities as a result of the acquisition of voting
         securities by the Sponsor or an Affiliated Company which, by reducing
         the number of voting securities outstanding, increases the proportional
         number of shares beneficially owned by such Person, provided, that if a
         Change in Control would occur but for the operation of this sentence
         and such Person becomes the Beneficial Owner of any additional voting
         securities (other than through the exercise of options granted under
         any stock option plan of the Sponsor or through a stock dividend or
         stock split), then a Change in Control shall occur.

         13.1 General Rule.

              (a) Subject to Sections 13.3 through 13.5 hereof, the total Annual
         Additions under the Plan to a Participant's Accounts for any Limitation
         Year shall not exceed the lesser of:

                  (i) Thirty Thousand Dollars ($30,000); or

                  (ii) Twenty-five percent (25%) of the Participant's
              Compensation, from the Company for the Limitation Year. For
              purposes of this Article XIII, the "Limitation Year" shall mean
              the Plan Year.

              (b) For the purpose of this Article XIII and XIV only, the term
         "Company" shall mean the Sponsor and any Affiliated Company whether or
         not such Affiliated Company has adopted the Plan pursuant to Section
         10.2. Solely for purposes of this Article XIII, an entity shall be
         considered an Affiliated Company by reference to Code Section 415(h).

         13.2 Annual Additions. For purposes of Section 13.1, the term "Annual
Additions" shall mean with respect to a Participant, for any Limitation Year
with respect to the Plan and each other defined contribution plan, within the
meaning of Code Section 415(k), maintained by the Company ("Defined Contribution
Plan"), the sum of the amounts determined under Sections 13.2(a), (b), (c), (d),
(e), (f) and (g) hereof:

              (a) All amounts contributed or deemed contributed by the Company.

              (b) All amounts contributed by the Participant.

              (e) Any amounts allocated for such Plan Year which amounts are
         derived from contributions paid or accrued after December 31, 1985, in
         taxable years ending after such date, which are attributable to post
         retirement medical or life insurance benefits allocated to the separate
         account of a key employee (as defined in Code Section 416(i) under Code
         Section 419A(d)(1).

              (f) Excess deferral amounts determined pursuant to Sections 4.5
         and 6.12.

                                       69

<PAGE>   76

              (g) Excess deferral amounts determined pursuant to Section 4.4 to
         the extent such amounts are distributed after the first April 15th
         following the close of the Participant's taxable year.

         Notwithstanding the foregoing, Sections 13.2(d) and 13.2(e) above shall
not be included in any amount treated as an Annual Addition for purposes of
applying the limitations contained in Section 13.1(a)(ii) above. A Participant's
Rollover Contributions shall not be considered Annual Additions.

         13.3 Other Defined Contribution Plans. If the Company maintains any
other Defined Contribution Plan, then each Participant's Annual Additions under
such Defined Contribution Plan shall be aggregated with the Participant's Annual
Additions under the Plan for the purposes of applying the limitations of Section
13.1.

         13.4 Adjustments for Excess Annual Additions. To the extent that the
Annual Additions on behalf of any Participant in a Limitation Year to the Plan
and all other Defined Contribution Plans exceed the limitations set forth in
Sections 13.1 through 13.3 hereof, such Participant's Annual Additions for the
Plan shall be reduced in the following order: (i) After Tax Deposits that are
not Matched Deposits, (ii) After Tax Deposits that are Matched Deposits, (iii)
Before Tax Deposits that are not Matched Deposits, (iv) Before Tax Deposits that
are Matched Deposits, and (v) Matching Contributions. The portion of the
reduction attributable to Participant Deposits shall be refunded to the
Participants and the balance attributable to Matching Contributions, if any,
shall be held unallocated in a 415 Suspense Account established for the purpose
of this Section 13.4 and shall be used to reduce Company Contributions for the
next limitation year (and succeeding limitation year, as necessary) for all
Participants in the Plan. The 415 Suspense Account shall be exhausted before any
Company contributions shall be allocated to the Accounts of Participants.

         13.5 Compensation. For the purpose of this Article XIII, Compensation
shall mean a Participant's earned income, wages, salaries, fees for professional
services, and other amounts received (without regard to whether or not an amount
is paid in cash) for personal services actually rendered in the course of
employment with the Company maintaining the Plan and shall be determined as

         includible in gross income (including, but not limited to, commissions
         paid salespeople, compensation for services on the basis of a
         percentage of profits, commissions on insurance premiums, tips,
         bonuses, fringe benefits, and reimbursements or other expense
         allowances under a nonaccountable plan as described in Regulation
         1.62-2(c)).

              (b) Compensation shall include any elective deferral as defined in
         Code Section 402(g)(3) and any amount which is contributed or deferred
         by the Company at the election of the Employee and which is not
         includible in the gross income of the Employee by reason of Code
         Sections 125 or 457.

                                       70

<PAGE>   77

              (c) Compensation shall not include (I) any employer contributions
         to a plan of deferred compensation which are not included in the
         Employee's gross income for the taxable year in which contributed, (ii)
         any distributions from a plan of deferred compensation, (iii) any
         amounts realized from the exercise of a non-qualified stock option or
         when restricted stock or property held by the Employee becomes either
         freely transferable or is no longer subject to a substantial risk of
         forfeiture under Code Section 83 if such option, stock, or property was
         granted to the Employee by the Company, (iv) any amounts realized from
         the sale, exchange, or other disposition of stock acquired under a
         qualified stock option, (v) any contribution for medical benefits
         (within the meaning of Code Section 419(f)(2) after termination of
         employment which is otherwise treated as an Annual Addition, and (vi)
         any amount otherwise treated as an Annual Addition under Code Section
         415(l)(1).

         13.6 Treatment of 415 Suspense Account Upon Termination. In the event
the Plan shall terminate at a time when all amounts in the 415 Suspense Account
have not been allocated to the Accounts of the Participants, the 415 Suspense
Account amounts shall be applied as follows:

              (a) The amount in the 415 Suspense Account shall first be
         allocated, as of the Plan termination date, to Participants in
         accordance with the allocation formula applicable to Company
         Contributions provided under Section 6.3.

              (b) If, after those allocations have been made, any further
         residue funds remain in the 415 Suspense Account, the residue may
         revert to the Company in accordance with applicable provisions of the
         Code, ERISA, and the regulations thereunder.

                                 TOP-HEAVY RULES

         14.1 Applicability. Notwithstanding any provision in the Plan to the
contrary, and subject to the limitations set forth in Section 14.8, the
requirements of Sections 14.4, 14.5, 14.6 and 14.7 shall apply under the Plan in
the case of any Plan Year in which the Plan is determined to be a Top-Heavy Plan
under the rules of Section 14.3. For the purpose of this Article XIV and XIII
only, the term "Company" shall mean the Sponsor and any Affiliated Company
whether or not such company has adopted the Plan pursuant to Section 10.2.

         14.2 Definitions. For purposes of this Article XIV, the following
special definitions and definitional rules shall apply:

              (a) The term "Key Employee" means any Employee or former Employee
         who, at any time during the Plan Year or any of the four preceding Plan
         Years, is or was:

                  (i) An officer of the Company having an annual Compensation
              greater than 50% of the amount in effect under Code Section
              415(b)(1)(A) for the Plan Year; provided, however, for such
              purposes no more than 50 Employees (or, if lesser, the greater of
              three Employees or 10% of the Employees) shall be treated as
              officers;

                  (ii) One of the ten Employees having annual Compensation from
              the Company of more than the limitation in effect under Code
              Section 415(c)(1)(A) and owning (or considered as owning within
              the meaning of Code Section 318) the largest interests in the
              Company. For this purpose, if two Employees have the same interest
              in the Company, the Employee having greater annual Compensation
              from the Company shall be treated as having a larger interest;

                  (iii) A Five Percent Owner of the Company; or

                  (iv) A One Percent Owner of the Company having an annual
              Compensation from the Company of more than $150,000.

              (b) The term "Five Percent Owner" means any person who owns (or is
         considered as owning within the meaning of Code Section 318) more than
         5% of the outstanding stock of the Company or stock possessing more
         than 5% of the total combined voting power of all stock of the Company.

              (c) The term "One Percent Owner" means any person who would be
         described in paragraph (b) if "1%" were substituted for "5%" each place
         where it appears therein.

              (d) The term "Non-Key Employee" means any Employee who is not a
         Key Employee.

                                       72

<PAGE>   79

              (e) The term "Determination Date" means, with respect to any plan
         year, the last day of the preceding plan year. In the case of the first
         plan year of any plan, the term "Determination Date" shall mean the
         last day of that plan year.

              (f) The term "Aggregation Group" means (i) each plan of the
         Company in which a Key Employee is a Participant, and (ii) each other
         plan of the Company which enables any plan described in clause (i) to
         meet the requirements of Code Sections 401(a)(4) or 410. Any plan not
         required to be included in an Aggregation Group under the preceding
         rules may be treated as being part of such group if the group would
         continue to meet the requirements of Code Sections 401(a)(4) and 410
         with the plan being taken into account.

              (g) For purposes of determining ownership under paragraphs (a),
         (b) and (c) above, the following special rules shall apply: (i) Code
         Section 318(a)(2)(C) shall be applied by substituting "5%" for "50%",
         and (ii) the aggregation rules of Code Sections 414(b), (c) and (m)
         shall not apply, with the result that the ownership tests of this
         Section 14.2 shall apply separately with respect to each Affiliated
         Company.

              (h) The terms "Key Employee" and "Non-Key Employee" shall include
         their Beneficiaries, and the definitions provided under this Section
         14.2 shall be interpreted and applied in a manner consistent with the
         provisions of Code Section 416(i) and the regulations thereunder.

              (i) For purposes of this Article XIV, an Employee's Compensation
         shall be determined in accordance with the rules of Section 13.5.

         14.3 Top-Heavy Status.

              (a) The term "Top-Heavy Plan" means, with respect to any Plan
         Year:

                  (i) Any defined benefit plan if, as of the Determination Date,
              the present value of the cumulative accrued benefits under the
              plan for Key Employees exceeds 60% of the present value of the
              cumulative accrued benefits under the plan for all Employees; and

                  (ii) Any defined contribution plan if, as of the Determination
              Date, the aggregate of the account balances of Key Employees under
              the plan exceeds 60% of the aggregate of the account balances of
              all Employees under the plan.

              In applying the foregoing provisions of this paragraph (a), the
         valuation date to be used in valuing Plan assets shall be (i) in the
         case of a defined benefit plan, the same date which is used for
         computing costs for minimum funding purposes, and (ii) in the case of a
         defined contribution plan, the most recent valuation date within a
         12-month period ending on the applicable Determination Date.

                                       73

<PAGE>   80

              (b) Each plan maintained by the Company required to be included in
         an Aggregation Group shall be treated as a Top-Heavy Plan if the
         Aggregation Group is a Top-Heavy Group.

              (c) The term "Top-Heavy Group" means any Aggregation Group if the
         sum (as of the Determination Date) of (i) the present value of the
         cumulative accrued benefits for Key Employees under all defined benefit
         plans included in the group, and (ii) the aggregate of the account
         balances of Key Employees under all defined contribution plans included
         in the group exceeds 60% of a similar sum determined for all Employees.
         For purposes of determining the present value of the cumulative accrued
         benefit of any Employee, or the amount of the account balance of any
         Employee, such present value or amount shall be increased by the
         aggregate distributions made with respect to the Employee under the
         plan during the five year period ending on the Determination Date. The
         preceding prior distribution rule shall also apply to distributions
         under a terminated plan that, if it had not been terminated, would have
         been required to be included in an Aggregation Group; provided,
         however, any rollover contribution or similar transfer initiated by the
         Employee and made after December 31, 1983, to a plan shall not be taken
         into account with respect to the transferee plan for purposes of
         determining whether such plan is a Top-Heavy Plan (or whether any
         Aggregation Group which includes such plan is a Top-Heavy Group).

              (d) If any individual is a Non-Key Employee with respect to any
         plan for any plan year, but the individual was a Key Employee with
         respect to the plan for any prior plan year, any accrued benefit for
         the individual (and the account balance of the individual) shall not be
         taken into account for purposes of this Section 14.3.

              (e) If any individual has not performed services for the Company
         at any time during the five year period ending on the Determination
         Date, any accrued benefit for such individual (and the account balance
         of the individual) shall not be taken into account for purposes of this
         Section 14.3

              (f) In applying the foregoing provisions of this Section, the
         accrued benefit of a Non-Key Employee shall be determined (i) under the
         method, if any, which is used for accrual purposes under all plans of
         the Company and any Affiliated Companies, or (ii) if there is no such
         uniform method, as if such benefit accrued not more rapidly than the
         slowest accrual rate permitted under Code Section 411(b)(1)(C).

              (g) For all purposes of this Article XIV, the definitions provided
         under this Section 14.3 shall be applied and interpreted in a manner
         consistent with the provisions of Code Section 416(g) and the
         regulations thereunder.

         14.4 Minimum Contributions. For any Plan Year in which the Plan is
determined to be a Top-Heavy Plan, the minimum employer contributions for that
year shall be determined in accordance with the rules of this Section 14.4.

              (a) Except as provided below, the minimum contribution for each
         Non-Key Employee shall be not less than 3% of his or her compensation.
         For purposes of satisfying the minimum contribution requirement, Before
         Tax Deposits and Matching Contributions as defined in Section
         6.13(b)(iv) shall not be taken into account.

              (b) Subject to the following rules of this paragraph (b), the
         percentage set forth in paragraph (a) above shall not be required to
         exceed the percentage at which contributions (including amounts
         deferred under a cash or deferred arrangement under Code Section
         401(k)) are made (or are required to be made) under the Plan for the
         year for the Key Employee for whom the percentage is the highest for
         the year. This determination shall be made by dividing the
         contributions for each Key Employee by so much of his or her total
         compensation for the Plan Year as does not exceed the applicable
         Compensation limit. For purposes of this paragraph (b), all defined
         contribution plans required to be included in an Aggregation Group
         shall be treated as one plan. Notwithstanding the foregoing, the
         exceptions to paragraph (a) as provided under this paragraph (b) shall
         not apply to any plan required to be included in an Aggregation Group
         if the plan enables a defined benefit plan to meet the requirements of
         Code Sections 401(a)(4) or 410.

              (c) The Participant's minimum contribution determined under this
         Section 14.4 shall be calculated without regard to any Social Security
         benefits payable to the Participant.

              (d) In the event a Participant is covered by both a defined
         contribution and a defined benefit plan maintained by the Company, both
         of which are determined to be Top-Heavy Plans, the Company shall
         satisfy the minimum benefit requirements of Code Section 416 by
         providing (in lieu of the minimum contribution described in paragraph
         (a) above) a minimum benefit under the defined benefit plan so as to
         prevent the duplication of required minimum benefits hereunder.

         14.5 Minimum Vesting Rules.

              (a) For any Plan Year in which it is determined that the Plan is a
         Top-Heavy Plan, the vesting schedule of the Plan shall be changed to
         that set forth below (unless the Plan's vesting schedule otherwise
         provides for vesting at a rate at least as rapid as that set forth
         below):

                Number of Full Years of                         Nonforfeitable
                Credited Service                                Percentage
                -----------------------                         --------------
                Less than 3 years                                      0%
                3 or more                                            100%

                                       75

<PAGE>   82

              (b) If the Plan ceases to be a Top-Heavy Plan, the vesting
         schedule of the Plan shall (for such Plan Years as the Plan is not a
         Top-Heavy Plan) revert to that provided in Section 7.2 (the "Regular
         Vesting Schedule"). If such reversion to the Regular Vesting Schedule
         is deemed to constitute a vesting schedule change that is attributable
         to a Plan amendment (within the meaning of Code Section 411(a)(10)),
         then such reversion to said Regular Vesting Schedule shall be subject
         to the requirements of Code Section 411(a)(10) of the Plan. For such
         purposes, the date of the adoption of such deemed amendment shall be
         the Determination Date as of which it is determined that the Plan has
         ceased to be a Top-Heavy Plan.

         14.6 Noneligible Employees. The rules of this Article XIV shall not
apply to any Employee included in a unit of employees covered by a collective
bargaining agreement between employee representatives and one or more employers
if retirement benefits were the subject of good faith bargaining between such
employee representatives and the employer or employers.

                                   ARTICLE XV
                          RESTRICTION ON ASSIGNMENT OR
                        OTHER ALIENATION OF PLAN BENEFITS

         15.1 General Restrictions Against Alienation.

              (a) The interest of any Participant or his or her Beneficiary in
         the income, benefits, payments, claims or rights hereunder, or in the
         Trust Fund, shall not in any event be subject to sale, assignment,
         hypothecation, or transfer. Each Participant and Beneficiary is
         prohibited from anticipating, encumbering, assigning, or in any manner
         alienating his or her interest under the Trust Fund, and is without
         power to do so, except as may be permitted in connection with providing
         security for a loan from the Plan to the Participant pursuant to the
         provisions of the Plan as it may be amended from time to time. The
         interest of any Participant or Beneficiary shall not be liable or
         subject to his or her debts, liabilities, or obligations, now
         contracted, or which may hereafter be contracted, and such interest
         shall be free from all claims, liabilities, or other legal process now
         or hereafter incurred or arising. Neither the interest of a Participant
         or Beneficiary, nor any part thereof, shall be subject to any judgment
         rendered against any such Participant or Beneficiary. Notwithstanding
         the foregoing, a Participant's or Beneficiary's interest in the Plan
         may be subject to the enforcement of a Federal tax levy made pursuant
         to Code Section 6331 or the collection by the United States on a
         judgment resulting from an unpaid tax assessment.

              (b) In the event any person attempts to take any action contrary
         to this Article XV, such action shall be null and void and of no
         effect, and the Company, the Committee, the Trustee and all
         Participants and their Beneficiaries, may disregard such action and are
         not in any manner bound thereby, and they, and each of them, shall
         suffer no liability for any such disregard thereof, and shall be
         reimbursed on demand out of the Trust Fund for the amount of any loss,
         cost or expense incurred as a result of disregarding or of acting in
         disregard of such action.

              (c) The foregoing provisions of this Section shall be interpreted
         and applied by the Committee in accordance with the requirements of
         Code Section 401(a)(13) and Section 206(d) of ERISA as construed and
         interpreted by authoritative judicial and administrative rulings and
         regulations.

         15.2 Qualified Domestic Relations Orders. The rules set forth in
Section 15.1 above shall not apply with respect to a "Qualified Domestic
Relations Order" as described below.

              (a) A "Qualified Domestic Relations Order" is a judgment, decree,
         or order (including approval of a property settlement agreement) that:

                  (i) Creates or recognizes the existence of an Alternate
              Payee's right to, or assigns to an Alternate Payee the right to,
              receive all or a portion of the benefits payable under the Plan
              with respect to a Participant,

                                       77

<PAGE>   84

                  (ii) Relates to the provision of child support, alimony
              payments, or marital property rights to a spouse, former spouse,
              child or other dependent of a Participant,

                  (iii) Is made pursuant to a State domestic relations law
              (including a community property law), and

                  (iv) Clearly specifies: (A) the name and last known mailing
              address (if any) of the Participant and the name and mailing
              address of each Alternate Payee covered by the order (if the
              Committee does not have reason to know that address independently
              of the order); (B) the amount or percentage of the Participant's
              benefits to be paid to each Alternate Payee, or the manner in
              which the amount or percentage is to be determined; (C) the number
              of payments or period to which the order applies; and (D) each
              plan to which the order applies.

              For purposes of this Section 15.2, "Alternate Payee" means any
         spouse, former spouse, child or other dependent of a Participant who is
         recognized by a domestic relations order as having a right to receive
         all, or a portion of, the benefits payable with respect to the
         Participant.

              (b) A domestic relations order is not a Qualified Domestic
         Relations Order if it requires:

                  (i) The Plan to provide any type or form of benefit, or any
              option, not otherwise provided under the Plan;

                  (ii) The Plan to provide increased benefits; or

                  (iii) The payment of benefits to an Alternate Payee that are
              required to be paid to another Alternate Payee under a previous
              Qualified Domestic Relations Order.

              (c) A domestic relations order shall not be considered to fail to
         satisfy the requirements of paragraph (b)(i) above with respect to any
         payment made before a Participant has separated from service solely
         because the order requires that payment of benefits be made to an
         Alternate Payee:

                  (i) On or after the date on which the Participant attains (or
              would have first attained) his or her earliest retirement age (as
              defined in Code Section 414(p)(4)(B));

                                       78

<PAGE>   85

                  (ii) As if the Participant had retired on the date on which
              such payment is to begin under such order (but taking into account
              only the present value of accrued benefits and not taking into
              account the present value of any subsidy for early retirement
              benefits); and

                  (iii) In any form in which such benefits may be paid under the
              Plan to the Participant (other than in the form of a joint and
              survivor annuity with respect to the Alternate Payee and his or
              her subsequent spouse).

              Notwithstanding the foregoing, if the Participant dies before his
         or her earliest retirement age (as defined in Code Section
         414(p)(4)(B)), the Alternate Payee is entitled to benefits only if the
         Qualified Domestic Relations Order requires survivor benefits to be
         paid to the Alternate Payee.

              (d) To the extent provided in any Qualified Domestic Relations
         Order, the former spouse of a Participant shall be treated as a
         surviving Spouse of the Participant for purposes of applying the rules
         (relating to minimum survivor annuity requirements) of Code Sections
         401(a)(11) and 417, and any current spouse of the Participant shall not
         be treated as a spouse of the Participant for such purposes.

              (e) In the case of any domestic relations order received by the
         Plan, the Committee shall promptly notify the Participant and any
         Alternate Payee named in the order that an order has been received and
         shall provide a copy of the Plan's procedures for determining the
         qualified status of domestic relations orders. An Alternate Payee may
         designate a representative for receipt of copies of notices and plan
         information that are sent to the Alternate Payee with respect to
         domestic relations order. Within a reasonable period after the receipt
         of the order, the Committee shall determine whether the order is a
         Qualified Domestic Relations Order and shall notify the Participant and
         each Alternate Payee of such determination.

              (f) The Committee shall establish reasonable procedures to
         determine the qualified status of domestic relations orders and to
         administer distributions under Qualified Domestic Relations Orders.
         During any period in which the issue of whether a domestic relations
         order is a Qualified Domestic Relations Order is being determined (by
         the Committee, by a court of competent jurisdiction, or otherwise), the
         Committee shall direct the Trustee to segregate in a separate account
         in the Plan (or in an escrow account) the amounts which would have been
         payable to the Alternate Payee during the period if the order had been
         determined to be a Qualified Domestic Relations Order. If within the 18
         Month Period (as defined below), the order (or modification thereof) is
         determined to be a Qualified Domestic Relations Order, the Committee
         shall direct the Trustee to pay the segregated amounts (plus any
         interest thereon) to the person or persons entitled thereto. However,
         if within the 18 Month Period (i) it is determined that the order is
         not a Qualified Domestic Relations Order, or (ii) the issue as to
         whether the order is a Qualified Domestic Relations Order is not
         resolved, then the Committee shall direct the Trustee to pay the
         segregated amounts (plus any interest thereon) to the person or persons
         who would have been entitled to the amounts if there had been no order
         (assuming such

                                       79

<PAGE>   86

         benefits were otherwise payable). Any determination that an order is a
         Qualified Domestic Relations Order that is made after the close of the
         18 Month Period shall be applied prospectively only. For purposes of
         this Section 15.2, the "18 Month Period" shall mean the 18 month period
         beginning with the date on which the first payment would be required to
         be made under the domestic relations order.

right is hereby expressly reserved.

         16.2 Effect of Article Headings. Article headings are for convenient

shall not exceed the limitation on contributions by or on behalf of the Top

Compensation Deferrals Contributions under the Plan by or on behalf of the Top

for any reason, such excess contributions shall be recharacterized as After Tax
Deposits or such excess contributions, adjusted for any income or loss allocable

         PR-Code as set forth in (i) below, or to the extent not precluded by
         applicable regulations, the alternate Actual Deferral Percentage test

                  (i) The average "Actual Deferral Percentage" for the Top
              One-Third Highly Compensated Employees shall not be more than the
              average Actual Deferral Percentage of all non-Top One-Third Highly
              Compensated Employees multiplied by 1.25, or

                  (ii) The excess of the average Actual Deferral Percentage for
              the Top One-Third Highly Compensated Employees over the average
              Actual Deferral Percentage for all non-Top One-Third Highly
              Compensated Employees shall not be more than two (2) percentage
              points and the average Actual Deferral Percentage for the Top
              One-Third Highly Compensated Employee shall not be more than the
              average Actual Deferral Percentage of all non-Top One-Third Highly
              Compensated Employees multiplied by 2.0.

              (b) For the purpose of this Section 4.3 only, the following
           definitions shall apply:

                  (i) "Actual Deferral Percentage" shall mean, with respect to
              the group of all Top One-Third Highly Compensated Employees and
              the group of all non-Top One-Third Highly Compensated Employees
              for a Plan Year, the ratio, calculated separately for each
              Participant in such group, of the amount of the Participant's
              Compensation Deferral Contribution for such Plan Year, to such
              Participant's Compensation for such Plan Year, in accordance with
              regulations prescribed by the Puerto Rico Secretary of the
              Treasury under PR-Code Section 1165(e). For purposes of computing
              the Actual Deferral Percentage, an Eligible Employee who would be
              a Participant but for the failure to make Before Tax Deposits
              shall be treated as a Participant on whose behalf no Before Tax
              Deposits are made.

                  (ii) "Participant" shall mean any Eligible Puerto Rico-based
              Employee who satisfied the requirements under Plan Article III
              during the Plan Year, whether or not such Eligible Employee
              elected to contribute to the Plan for such Plan Year.

                  (iii) "Compensation Deferral Contributions" shall mean amounts
              contributed to the Plan by a Participant as Before Tax Deposits
              pursuant to Section 4.1 of this Appendix, including excess Before
              Tax Deposits (as defined in Plan Section 4.4(a)) of the Top
              One-Third Highly Compensated Employees but excluding (1) excess
              Before Tax Deposits of all non-Top One-Third Highly Compensated
              Employees that arise solely from Before Tax Deposits made under
              the Plan or plans of the Company, (2) Before Tax Deposits that are
              taken into account in the Average Contribution Percentage test (as
              defined in Plan Section 6.11) provided that the Actual Deferral
              Percentage test is satisfied both with and without exclusions of
              these Before Tax Deposits, and (3) any deferrals properly
              distributed as excess Annual Additions. To the extent determined
              by the Committee and in accordance with regulations issued by the
              Puerto Rico Secretary of the Treasury, matching contributions and
              qualified nonelective contributions on behalf of a Participant
              that satisfy the requirements of PR-Code Section 1165(e)(3)(D)(ii)
              may also be taken into account for the purpose of determining the
              Actual Deferral Percentage of such Participant.

                  (iv) "Compensation" shall mean compensation as described
              below:

                       (1) Compensation means compensation determined by the
                  Company in accordance with the requirements of Code Section
                  414(s) and the regulations thereunder.

                       (2) For the purpose of this Section 4.3, Compensation
                  may, at the Company's election, include amounts which are
                  excludable from a Participant's gross income under Code
                  Section 125 (pertaining to cafeteria plans) and Code Section
                  402(e)(3) (pertaining to 401(k) salary reductions).

                                      A-4

<PAGE>   94

                  The Company may change its election provided such change does
                  not discriminate in favor of the Top One-Third Highly
                  Compensated Employees.

                       (3) Compensation taken into account for any Plan Year
                  shall not exceed $150,000 as adjusted at the time and in such
                  manner as permitted under Code Section 401(a)(17)(B).

              (c) In the event that as of the first day of Plan Year, the Plan
         satisfies the requirements of PR-Code Section 1165(a) only if
         aggregated with one or more other plans which include arrangements
         under PR-Code Section 1165(e), then this Section 4.3 shall be applied
         by determining the Actual Deferral Percentages of Participants as if
         all such plans were a single plan, in accordance with regulations
         prescribed by the Secretary of the Treasury under PR-Code Section
         1165(e). Plans may be considered one plan for purposes of satisfying
         PR-Code Section 1165(e) only if they have the same Plan Year.

              (d) For the purpose of this Section 4.3, the "Actual Deferral
         Percentage" for any Top One-Third Highly Compensated Employee who is a
         Participant under two or more PR-Code Section 1165(e) arrangements of
         the Company shall be determined by taking into account the Top
         One-Third Highly Compensated Employee's Compensation under each such
         arrangement and contributions under each such arrangement which qualify
         for treatment under PR-Code Section 1165(e) in accordance with
         regulations prescribed by the Puerto Rico Secretary of the Treasury
         under PR-Code Section 1165(e). If the arrangements have different Plan
         Years, this subSection shall be applied by treating all such
         arrangements ending with or within the same calendar year as a single
         arrangement. Notwithstanding the foregoing, certain plans shall be
         treated as separate plans if mandatorily disaggregated pursuant to
         regulations under Code Section 401(k).

              (e) For purposes of the Actual Deferral Percentage test,
         Compensation Deferral Contributions must be made before the last day of
         the twelve-month period immediately following the Plan Year to which
         such contributions relate.

              (f) The determination and treatment of Compensation Deferral
         Contributions and the Actual Deferral Percentage of any Participant
         under this Section 4.3 shall satisfy such other requirements as may be
         prescribed by the Puerto Rico Secretary of the Treasury.

              (g) The Committee shall keep or cause to have kept such records as
         are necessary to demonstrate that the Plan satisfies the requirements
         of PR-Code Section 1165(e) and the regulations thereunder, in
         accordance with regulations prescribed by the Puerto Rico Secretary of
         the Treasury.

it as contributions hereunder, and as is acceptable to it, hereinafter referred
to as the "Trust Fund," but shall not be under any duty to require the Company
to contribute to the Trust Fund or to determine whether the amount of any
contribution has been correctly computed under the terms of the Plan. In no
event shall the Trustee be considered a party to the Plan. The Trustee shall
have only such duties with respect to the Plan as are set forth in this
Agreement.

         SECOND: INVESTMENT POWERS.

         The Trustee shall invest the assets of the Trust Fund as directed by
the Sponsor, Committee, or Participants in accordance with the provisions of the
Plan. In doing so, the Trustee will be a directed trustee. Trust investments may
include, without limitation, employer securities, as that term is defined in
section 407(d) of ERISA, hereinafter referred to as "Company Stock, " without
regard to limitations imposed by section 407(a) of ERISA, and any fund created
for the collective investment of the assets of employee benefit trusts, as long
as such collective investment fund is a qualified trust under the applicable
provisions of the Code (and while any portion of the Trust Fund is so invested,
such collective investment fund shall constitute a part of the Plan, and the
instruments creating such fund shall constitute a part of this Agreement). The
Trustee shall have no independent investment duties or responsibilities. The
Trustee assumes no financial responsibility with respect to the investment of
the assets of the Trust Fund. If the Trustee properly carries out such
investment directions, the Trustee will have no liability for any loss or
diminution in value occasioned thereby.

         To the maximum extent permitted by law, the Trustee shall not be liable
for the acquisition, retention or disposition of any assets of the Trust Fund or
for any loss to or diminution of such assets unless due to the Trustee's own
negligence or willful misconduct.

         The Committee may appoint an "investment manager," as defined in
section 3(38) of ERISA. Any investment manager so appointed shall be (i) an
investment adviser registered as such under the Investment Advisers Act of 1940,
(ii) a bank, or (iii) an insurance company qualified to perform investment
management services under the laws of more than one state of the United States.
The Committee shall notify the Trustee of any such appointment by delivering to
the Trustee an executed copy of the instrument under which the investment
manager is appointed and evidencing the investment manager's acceptance of such
appointment, an acknowledgment by the investment manager that it is a fiduciary
of the Plan, and a certificate evidencing the investment manager's current
registration under the Investment Advisers Act of 1940 or other appropriate
qualification. The Committee shall specify to the Trustee the portion of the
Trust Fund that shall be subject to such investment management. The Trustee
shall invest and reinvest the portion of the Trust Fund subject to such
investment management only to the extent and in the manner directed by the
investment manager in writing. During the term of such appointment, the Trustee
shall have no liability for the acts or omissions of such investment manager,
and except as provided in the preceding sentence, shall be under no obligation
to invest

                                      -2-

<PAGE>   5

or otherwise manage the portion of the Trust Fund subject to such investment
management. The Trustee may maintain separate accounts within the Trust Fund for
the assets of the Trust Fund subject to such investment management. The
Committee may terminate its appointment of an investment manager at any time and
shall notify the Trustee in writing of such termination. To the maximum extent
permitted by ERISA, the Trustee shall be protected in assuming that the
appointment of an investment manager remains in effect until it is otherwise
notified in writing by the Committee.

         In the event that the investment manager appointed hereunder is a bank
or a trust company, or an affiliate of a bank or a trust company, the Trustee
shall, upon the direction of the Committee, transfer funds to such bank, trust
company, or affiliate for investment through the medium of any fund created and
administered by such bank, trust company, or affiliate, acting as trustee
therefore, for the collective investment of the assets of employee benefit
trusts, provided that such fund is qualified under the applicable provisions of
the Code and that while any portion of the assets are so invested, such fund
shall constitute part of the applicable Plan or Plans, and the instrument
creating such fund shall constitute part of this Agreement. In order to
implement the provisions of this paragraph, the Trustee is authorized to enter
into any required ancillary trust, agency or other type of agreement with an
investment manager, or its affiliate, as described in the preceding sentence.

         The Trustee shall have no power or duty to sell, tender, exchange, or
otherwise dispose of any Company Stock held in the Fund, hereinafter referred to
as the "Company Stock Fund," except in the following circumstances: (i) in the
event of a tender or exchange offer as hereinafter provided, (ii) in the case of
fractional shares received in any stock dividend, stock split or other
recapitalization, (iii) as necessary to make any distribution or payment from
the Trust Fund, (iv) pursuant to the direction of the Sponsor, Committee, or a
Participant, or (v) where ERISA prohibits the limitation of the Trustee's power.
In the event that an offer (including but not limited to a tender offer or
exchange offer within the meaning of the Securities Exchange Act of 1934, as
from time to time amended and in effect) (the "Offer") is made for all or any
portion of the Company Stock held in the Company Stock Fund, and notwithstanding
any other provision of the Trust to the contrary, the Trustee's discretion or
authority to sell, exchange or transfer any of such Company Stock held in the
Company Stock Fund shall be determined in accordance with the following rules:

         (1)  The Trustee shall have no discretion or authority to sell,
              exchange or transfer any Company Stock pursuant to an Offer except
              to the extent, and only to the extent, that the Trustee is timely
              directed to do so in writing by each Participant with respect to
              shares of Company Stock that are allocated to such Participant's
              accounts.

         (2)  To the extent there remains any residual fiduciary responsibility
              with respect to Company Stock pursuant to an Offer after
              application of subparagraph (1) above, the Trustee shall sell,
              exchange or transfer such Company Stock as directed by the
              Committee or as directed by an independent fiduciary if duly
              appointed by the Sponsor.

                                      -3-

<PAGE>   6

         (3)  Upon timely receipt of such instructions, the Trustee shall,
              subject to the provisions of subparagraphs (5) and (15) of this
              paragraph, sell, exchange or transfer pursuant to such Offer, only
              such shares of Company Stock as to which such instructions were
              given.

         (4)  In the event, under the terms of an Offer or otherwise, any shares
              of Company Stock tendered for sale, exchange or transfer pursuant
              to such Offer may be withdrawn from such Offer, the Trustee shall
              follow such instructions respecting the withdrawal of such shares
              from such Offer in the same manner and the same proportion as
              shall be timely received by the Trustee from the Participants
              entitled under this paragraph to give instructions as to the sale,
              exchange or transfer of shares pursuant to such Offer.

         (5)  In the event that an Offer for fewer than all of the shares of
              Company Stock held by the Trustee in the Trust shall be received
              by the Trustee, each Participant shall be entitled to direct the
              Trustee as to the acceptance or rejection of such Offer (as set
              forth herein) with respect to the largest portion of such Company
              Stock as may be possible given the total number or amount of
              shares of Company Stock the Plan may sell, exchange or transfer
              pursuant to the Offer based upon the instructions received by the
              Trustee from all other Participants who shall timely instruct the
              Trustee pursuant to this paragraph to sell, exchange or transfer
              such shares pursuant to such Offer, each on a pro rata basis in
              accordance with the maximum number of shares each such Participant
              would have been permitted to direct under subparagraph (1) had the
              Offer been for all shares of Company Stock held in the Trust.

         (6)  In the event an Offer is received by the Trustee and instructions
              have been solicited from Participants regarding such Offer, and
              prior to termination of such Offer, another Offer is received by
              the Trustee for the Company Stock subject to the first Offer, the
              Trustee shall inform the Committee of such other Offer and the
              Committee shall use its best efforts under the circumstances to
              solicit instructions from the Participants (i) with respect to
              securities tendered for sale, exchange or transfer pursuant to the
              first Offer, whether to withdraw such tender, if possible, and, if
              withdrawn, whether to tender any Company Stock so withdrawn for
              sale, exchange or transfer pursuant to the second Offer and (ii)
              with respect to Company Stock not tendered for sale, exchange or
              transfer pursuant to the first Offer, whether to tender or not to
              tender such Company Stock for sale, exchange or transfer pursuant
              to the second Offer. The Trustee shall follow all such
              instructions received in a timely manner from Participants in the
              same manner and in the same proportion as provided in subparagraph
              (1). With respect to any further Offer for any Company Stock
              received by the Trustee and subject to any earlier Offer
              (including successive Offers from one or more existing offers),
              the Trustee shall act in the same manner as described above.

                                      -4-

<PAGE>   7

         (7)  With respect to any Offer received by the Trustee, the Trustee
              shall inform the Sponsor of such Offer and the Sponsor shall
              distribute, at its expense, copies of all relevant material
              including but not limited to material filed with the Securities
              and Exchange Commission with such Offer or regarding such Offer,
              which shall seek confidential written instructions from each
              Participant who is entitled to respond to such Offer pursuant to
              subparagraph (1).

         (8)  The Sponsor shall distribute and/or make available to each
              Participant who is entitled to respond to an Offer pursuant to
              subparagraph (1), an instruction form to be used by each such
              Participant who wishes to instruct the Trustee. The instruction
              form shall state that (i) if the Participant fails to return an
              instruction form to the Trustee by the indicated deadline, the
              Company Stock with respect to which he or she is entitled to give
              instructions shall not be sold, exchanged or transferred pursuant
              to such Offer, (ii) the Participant shall be a named fiduciary (as
              described in subparagraph (13) below) with respect to all shares
              of Company Stock for which he or she is entitled to give
              instructions, and (iii) the Company acknowledges and agrees to
              honor the confidentiality of the Participant's instructions to the
              Trustee.

         (9)  Each Participant may choose to instruct the Trustee in one of the
              following two ways: (i) not to sell, exchange or transfer any
              shares of Company Stock for which he or she is entitled to give
              instructions, or (ii) to sell, exchange or transfer all Company
              Stock for which he or she is entitled to give instructions. The
              Sponsor shall follow up with additional mailings and postings of
              bulletins, as reasonable under the time constraints then
              prevailing, to obtain instructions from Participants not otherwise
              responding to such requests for instructions. Subject to
              subparagraph (4), the Trustee shall then sell, exchange or
              transfer shares of Company Stock according to instructions from
              Participants, except that shares for which no instructions are
              received shall not be sold, exchanged or transferred unless
              directed otherwise as provided in subparagraph (2) above.

         (10) The Sponsor shall furnish former Participants who have received
              distributions of Company Stock so recently as to not be
              shareholders of record with the information given to Participants
              pursuant to subparagraphs (7), (8), and (9). The Trustee shall
              then sell, exchange or transfer shares according to instructions
              from such former Participants, except that shares for which no
              instructions are received shall not be sold, exchanged or
              transferred.

         (11) Neither the Company, the Committee nor the Trustee shall express
              any opinion or give any advice or recommendation to any
              Participant concerning the Offer, nor shall they have any
              authority or responsibility to do so.

         (12) The Trustee shall not reveal or release a Participant's
              instructions to the Company, its officers, directors, employees,
              or representatives. If some but not all Company Stock held by the
              Trust is sold, exchanged, or transferred pursuant to an Offer, the

                                      -5-

<PAGE>   8

              Company, with the Trustee's cooperation, shall take such action as
              is necessary to maintain the confidentiality of Participant's
              records including, without limitation, establishment of a security
              system and procedures which restrict access to Participant records
              and retention of an independent agent to maintain such records. If
              an independent record keeping agent is retained, such agent must
              agree, as a condition of its retention by the Sponsor, not to
              disclose the composition of any Participant Accounts to the
              Company, its officers, directors, employees, or representatives.
              The Company acknowledges and agrees to honor the confidentiality
              of Participants' instructions to the Trustee.

         (13) Each Participant shall be a named fiduciary (as that term is
              defined in section 402(a)(2) of ERISA) with respect to Company
              Stock allocated to his or her accounts under the Plan solely for
              purposes of exercising the rights of a shareholder with respect to
              an Offer pursuant to this paragraph.

         (14) To the extent that an Offer results in the sale of Company Stock
              in the Trust, the Committee or the Participants, if so permitted
              under the terms of the Plan, shall instruct the Trustee as to the
              investment of the proceeds of such sale.

         (15) In the event a court of competent jurisdiction shall issue to the
              Plan, the Committee, the Sponsor or the Trustee an opinion or
              order, which shall, in the opinion of counsel to the Committee,
              the Sponsor or the Trustee, invalidate, in all circumstances or in
              any particular circumstances, any provision or provisions of this
              paragraph regarding the determination to be made as to whether or
              not Company Stock held by the Trustee shall be sold, exchanged or
              transferred pursuant to an Offer or cause any such provision or
              provisions to conflict with securities laws, then, upon notice
              thereof to the Committee, the Sponsor or the Trustee, as the case
              may be, such invalid or conflicting provisions of this paragraph
              shall be given no further force or effect. In such circumstances,
              the Trustee shall continue to follow instructions received from
              Participants, to the extent such instructions have not been
              invalidated by such order or opinion. To the extent the Trustee is
              required by such opinion or order to exercise any residual
              fiduciary responsibility with respect to such Offer, the Sponsor
              shall appoint an independent fiduciary who shall direct the
              Trustee as to whether or not Company Stock held by the Trustee
              shall be sold, exchanged or transferred pursuant to such Offer.

         All property received in exchange for such Company Stock so tendered
shall upon receipt be held by the Trustee in the Fund within the accounts of
those Participants who so tendered, the provisions of this Agreement shall
hereby be deemed amended to permit the holding of such property within said Fund
and the property shall thereafter be administered, invested, reinvested and
distributed in accordance with the applicable terms of the Plan and Trust.

         All dividends paid to the Trustee with respect to the Company Stock
Fund shall be held in the Trust by the Trustee as directed by the Committee.

                                      -6-

         THIRD: PAYMENTS.

         Subject to the provisions of Article FOURTEENTH hereof, the Trustee
shall from time to time transfer cash or other property from the Trust Fund to
such persons, including an insurance company or companies or a paying agent
designated by the Committee, at such addresses, in such amounts, for such
purposes and in such manner as the Committee may direct, provided that such
transfer is administratively feasible, and the Trustee shall incur no liability
for any such payment made at the direction of the Committee. The Committee shall
be solely responsible to insure that any payment made at its direction conforms
with the provisions of the Plan, the provisions of this Agreement, and ERISA,
and the Trustee shall have no duty to determine the rights or benefits of any
person in the Trust Fund or under the Plan or to inquire into the right or power
of the Committee to direct any such payment.

         FOURTH: ADMINISTRATIVE POWERS.

              options, the making of agreements or subscriptions and the
              payments of expenses, assessments or subscriptions, which may be
              deemed necessary or advisable in connection therewith and to hold

              otherwise, provided that, except as provided in Article FIFTH, the
              Trustee shall be the sole owner of all such contracts or policies
              and all such contracts or policies shall be held as assets of the
              Trust Fund upon the written direction of the Committee;

         (12) power to make, execute and deliver, as Trustee, any and all deeds,
              leases, notes, bonds, guarantees, mortgages, conveyances,
              contracts, waivers, releases or other instruments in writing
              necessary or proper for the accomplishment of any of the foregoing
              powers;

         (13) power to transfer assets of the Trust Fund to a successor trustee
              as provided in Article TWELFTH; and

         (14) power to appoint custodians or subcustodians to hold any or all of
              the Trust Fund upon the written direction or consent of the
              Committee;

         (15) power to appoint ministerial agents to perform various functions
              of the Trustee upon the written direction or consent of the
              Committee; and

         (16) power to exercise, subject to the terms and restrictions set forth
              in Article Fourth and the provisions of the Plan, generally, any
              of the powers that an individual owner might exercise in
              connection with property either real, personal or mixed held by
              the Trust Fund, and to do all other acts that the Trustee may deem
              necessary or proper to carry out any of the powers set forth in
              this Article FOURTH or otherwise in the best interests of the
              Trust Fund.

         Notwithstanding any other provision of the Trust to the contrary, the
Trustee shall have no discretion or authority to vote Company Stock held in the
Trust on any matter presented for a vote by the stockholders of the Company
except in accordance with timely directions received by the Trustee from either
the Committee or Participants, depending on who has the right to direct the
voting of such Company Stock as provided in the following subparagraphs:

         (1)  All Company Stock held in the Trust Fund shall be voted by the
              Trustee as the Committee directs in its absolute discretion,
              except as provided in this subparagraph (1).

              (i)   If the Sponsor has a registration-type class of securities
                    (as defined in section 409(e)(4) of the Code), then with
                    respect to all corporate matters, each Participant shall be
                    entitled to direct the Trustee as to the voting of all
                    Company Stock allocated and credited to his or her accounts.

              (ii)  If the Sponsor does not have a registration-type class of
                    securities, then only with respect to such matters as the
                    approval or disapproval of any

                                      -9-

<PAGE>   12

                    corporate merger or consolidation, recapitalization,
                    reclassification, liquidation, dissolution, sale of
                    substantially all assets of trade or business, or such
                    similar transactions as may be prescribed in regulations
                    under section 409(e)(4) of the Code, each Participant shall
                    be entitled to direct the Trustee as to the voting of all
                    Company Stock allocated and credited to the his or her
                    accounts.

         (2)  To the extent there remains any residual fiduciary responsibility
              with respect to the voting of Company Stock after application of
              subparagraph (1) above, the Trustee shall vote such Company Stock
              as directed by the Committee or as directed by an independent
              fiduciary if duly appointed by the Sponsor.

         (3)  All Participants entitled to direct such voting shall be notified
              by the Sponsor, pursuant to its normal communications with
              shareholders, of each occasion for the exercise of such voting
              rights within a reasonable time before such rights are to be
              exercised. Such notification shall include all information
              distributed to shareholders either by the Company or any other
              party regarding the exercise of such rights. Such Participants
              shall be so entitled to direct the voting of fractional shares (or
              fractional interests in shares), provided, however, that the
              Trustee may, to the extent possible, vote the combined fractional
              shares (or fractional interests in shares) so as to reflect the
              aggregate direction of all Participants giving directions with
              respect to fractional shares (or fractional interests in shares).
              To the extent that a Participant shall fail to direct the Trustee
              as to the exercise of voting rights arising under Company Stock
              credited to his or her account, such Company Stock shall not be
              voted unless the Trustee is directed otherwise as provided in
              subparagraph (2) above. The Trustee shall maintain confidentiality
              with respect to the voting directions of all Participants.

         (4)  Each Participant shall be a named fiduciary (as that term is
              defined in section 402(a)(2) of ERISA) with respect to Company
              Stock for which he or she has the right to direct the voting under
              the Plan but solely for the purpose of exercising voting rights
              pursuant to this paragraph.

         (5)  In the event a court of competent jurisdiction shall issue an
              opinion or order to the Plan, the Committee, the Sponsor or the
              Trustee, which shall, in the opinion of counsel to the Committee,
              the Sponsor or the Trustee, invalidate under ERISA, in all
              circumstances or in any particular circumstances, any provision or
              provisions of this paragraph regarding the manner in which Company
              Stock held in the Trust shall be voted or cause any such provision
              or provisions to conflict with ERISA, then, upon notice thereof to
              the Committee, the Sponsor or the Trustee, as the case may be,
              such invalid or conflicting provisions of this paragraph shall be
              given no further force or effect. In such circumstances the
              Trustee shall continue to follow instructions received from
              Participants, to the extent such instructions have not been
              invalidated by such order or opinion. To the extent the Trustee is
              required by such opinion or order to exercise any residual
              fiduciary responsibility with

                                      -10-

<PAGE>   13

              respect to voting, the Sponsor shall appoint an independent
              fiduciary who shall direct the Trustee as to the manner in which
              Company Stock held by the Trustee shall be voted.

         Notwithstanding the foregoing paragraphs, in the event that an
investment manager is appointed pursuant to Article SECOND hereof, such
investment manager shall exercise such of the powers enumerated in this Article
FOURTH and otherwise contained in this Agreement with respect to the portion of
the Trust Fund subject to its control as may be specified in the instrument
under which the investment manager was appointed.

         FIFTH: INSURANCE COMPANY CONTRACTS.

         The Trustee may, at the direction of the Committee, (i) enter into one
or more contracts with legal reserve life insurance companies, the rate of
return from which is fixed by the terms of such contracts, (ii) transfer to any
such insurance companies a portion of the Trust Fund in accordance with any such
contracts, and (iii) hold any such contracts as a part of the Trust Fund until
directed otherwise by the Committee. The Committee shall give such direction to
the Trustee by delivering to the Trustee a copy of the action of the Committee
which shall specifically refer to this Article FIFTH and direct the Trustee to
so act. The Committee may direct the Trustee to (i) request any information from
any such insurance companies necessary or appropriate to make an investment
decision, (ii) demand or accept withdrawals or other distributions under any
such contracts, (iii) exercise or not to exercise any rights, powers, privileges
and options under any such contracts and (iv) assign, amend, modify or terminate
any such contracts. The Trustee shall take no action with respect to any such
contracts except at the direction of the Committee. The Trustee shall incur no
liability for complying with any direction of the Committee, and in the absence
of any direction from the Committee, the Trustee shall incur no liability for
failing to take any action. Any insurance companies issuing any contracts as
hereinabove described may deal with the Trustee as the absolute owner of any
such contracts and need not inquire as to the authority of the Trustee to act
with regard to such contracts. Any such insurance company may accept and rely
upon any communication from the Trustee that is signed by an officer of the
Trustee. For purposes of this Agreement, any such insurance company shall be
considered to be an investment manager with regard to the assets of the Plan
subject to its control. In no event shall the underlying assets of such
insurance company in which such contracts are invested be considered assets of
the Plan or part of the Trust Fund.

         SIXTH: FIDUCIARY STANDARDS.

         The Trustee (or any investment manager appointed pursuant to Article
SECOND hereof) shall (i) discharge its duties hereunder with the care, skill,
prudence and diligence under the circumstances then prevailing that a prudent
person acting in a like capacity and familiar with such matters would use in the
conduct of an enterprise of a like character and with like aims; (ii) subject to
the investment funds specified in the Plan, if any, and to the extent required
by ERISA, diversify the investments of the Trust Fund so as to minimize the risk
of large losses unless under the circumstances it is clearly prudent not to do
so; and (iii) discharge its duties in accordance

                                      -11-

<PAGE>   14

with the provisions of the Plan and this Agreement insofar as such provisions
are consistent with ERISA.

         The Trustee (or any investment manager appointed pursuant to Article
SECOND hereof) shall not engage in any transaction that it knows or should know
violates section 406 of ERISA. Notwithstanding the foregoing, the Trustee (or
any investment manager appointed pursuant to Article SECOND hereof) may, in
accordance with any appropriate exemption provided under ERISA or upon the
approval of the Secretary of the Department of Labor, enter into any transaction
otherwise prohibited under section 406 of ERISA.

         The Trustee shall not be responsible for the administration of the
Plan, for determining the funding policy of the Plan, or the adequacy of the
Trust Fund to meet and discharge liabilities under the Plan.

         The Trustee shall not be responsible for any failure of the Committee
or the Company to discharge any of their respective responsibilities with
respect to the Plan nor be required to enforce payment of any contributions to
the Trust Fund.

         SEVENTH: PROHIBITION OF DIVERSION.

         (1)  At no time prior to the satisfaction of all liabilities with
              respect to Participants in the Plan and their beneficiaries shall
              any part of the corpus or income of the Trust Fund be used for, or
              diverted to, purposes other than for the exclusive benefit of such
              Participants and their beneficiaries. Except as provided in
              subparagraphs (2), (3) and (4) below, and Article THIRTEENTH, or
              as otherwise permitted under the provisions of the Plan, the
              assets of the Trust Fund shall never inure to the benefit of the
              Company and shall be held for the exclusive purpose of providing
              benefits to Participants in the Plan and their beneficiaries and
              defraying the reasonable expenses of administering the Plan.

         (2)  In the case of a contribution that is made by the Company by a
              mistake of fact, subparagraph (1) above shall not prohibit the
              return to the Company of such contribution at the direction of the
              Committee within one year after the payment of the contribution.

         (3)  If a contribution by the Company is expressly conditioned on
              qualification of the Plan under section 401 of the Code, and if
              the Plan does not so qualify, then subparagraph (1) above shall
              not prohibit the return to the Company of such contribution at the
              direction of the Committee within one year after the date of
              denial of qualification of the Plan, to the extent permitted by
              ERISA and the Code.

         (4)  If a contribution by the Company is expressly conditioned upon the
              deductibility of the contribution under section 404 of the Code,
              then to the extent such deduction is disallowed, subparagraph (1)
              above shall not prohibit the return to

                                      -12-

<PAGE>   15

              the Company of such contribution at the direction of the
              Committee, to the extent disallowed, within one year after the
              date of such disallowance.

         EIGHTH: HOLD HARMLESS.

         To the maximum extent permitted by ERISA and other applicable law, the
Trustee shall not be liable for and the Company shall indemnify the Trustee
against, and agrees to hold the Trustee harmless from, all liabilities and
claims (including reasonable attorney's fees and expenses in defending against
such liabilities and claims) against the Trustee, arising from the Trustee's
performance of its duties in conformance with the terms of the Plan and this
Agreement, including any liability and claim arising with regard to the
provisions of Article SECOND, unless such liability or claim results from
negligent, reckless, or willful acts of commission or omission by the Trustee or
results from the Trustee's violation of ERISA or other applicable laws. To the
maximum extent permitted by ERISA and other applicable law, the Trustee shall
not be liable for acting (or for taking no action) in accordance with any
written direction of the Committee or an investment manager designated under
Article SECOND, or, where an investment manager has been designated, failing to
act in the absence of any such direction, including, without limitation, any
claim or liability that may be asserted against the Trustee on account of
failure to receive securities purchased, or failure to deliver securities sold
pursuant to orders issued by an investment manager, and the Company shall
indemnify the Trustee against and agrees to hold the Trustee harmless from, all
such liabilities and claims (including attorney's fees and expenses in defending
against such liabilities and claims). The foregoing indemnifications shall also
apply to liabilities and claims against the Trustee arising from any breach of
fiduciary responsibility by a fiduciary other than the Trustee, unless the
Trustee (i) participates knowingly in or knowingly undertakes to conceal such
breach, (ii) has enabled such fiduciary to commit such breach by its failure to
exercise its fiduciary duties under ERISA or (iii) has actual knowledge of such
breach and fails to take reasonable remedial action to remedy such breach.

         NINTH: ACCOUNTS.

         The Trustee or its agent shall keep records of all transactions
relating to the Trust Fund, which shall be made available at all reasonable
times to the Committee, persons designated by the Board of Directors of the
Sponsor or as may be required by law. The Trustee or its agent shall render an
accounting to the Company and the Committee at least annually which shall be in
a form sufficient to produce financial statements and to conduct an audit as
required by ERISA and the Code. The Committee may approve such accounting on
behalf of itself and the Company by an instrument in writing delivered to the
Trustee. If the Committee does not file with the Trustee objections to any such
accounting within sixty (60) days after its receipt, the Committee shall be
deemed to have approved such accounting on behalf of itself and the Company. In
such case, or upon the written approval of the Committee of any such accounting,
the Trustee shall, to the extent permitted by law, be discharged from all
liability to the Committee and the Company for its acts or failures to act
described in such accounting. Except to the extent otherwise provided in ERISA,
no person, other than the Company or the Committee, may require an accounting or
bring any action against the Trustee with respect to the Trust Fund. The Trustee

                                      -13-

<PAGE>   16

shall render to the Committee, at least quarterly, a statement of the Trust Fund
assets and their values and, whenever a contribution is made to the Trust Fund
other than in cash, a statement of the value of such property on the date it is
received by the Trustee.

         Nothing contained in this Agreement or in the Plan shall deprive the
Trustee of the right to have judicial settlement of its accounts. In any
proceeding for a judicial settlement of the Trustee's accounts, or for
instructions with regard to the Trust, the only necessary parties thereto in
addition to the Trustee shall be the Committee. If the Trustee so elects, it may
join as a party or parties any other person or persons.

         TENTH: COMMITTEE.

         The Sponsor shall certify to the Trustee the name of the entity,
person, or persons from time to time constituting the Committee. All directions
to the Trustee by the Committee shall be in writing, and the Trustee shall be
entitled to rely without further inquiry upon all such written directions
received from the Committee. The Committee shall in its sole discretion have the
right to appoint such agents as it may deem necessary to carry out its duties
pursuant to the provisions of the Plan and this Trust. If necessary or
appropriate the Committee shall notify the Trustee in writing as to the identity
and authority of any such agent, which notice shall be effective upon receipt by
the Trustee and shall remain effective until notice of the termination of any
such agent's authority is given to the Trustee.

         ELEVENTH: COMPENSATION AND EXPENSES.

         The Trustee shall be entitled to receive such reasonable compensation
for its services as may be agreed upon from time to time by the Sponsor and the
Trustee. Unless paid by the Company, such compensation, attorneys' fees that
were incurred with the Committee's approval in the administration of the Trust
Fund, all taxes levied or assessed against the Trust Fund, and such other
expenses as are incurred in the administration of the Trust Fund shall be paid
from the Trust Fund.

         TWELFTH: RESIGNATION OF TRUSTEE.

         The Trustee may resign at any time by giving thirty (30) days written
notice to the Sponsor. An authorized officer of the Sponsor may remove the
Trustee at any time by giving thirty (30) days written notice to the Trustee
unless the Trustee shall accept as adequate a shorter notice. In the case of the
resignation or removal of the Trustee, an authorized officer of the Sponsor
shall appoint a successor trustee who shall have the same powers and duties as
those conferred upon the Trustee. Upon the resignation or removal of the Trustee
and the appointment of the successor trustee, the Trustee shall account for the
administration of the Trust Fund up to the date of its resignation or removal in
the manner provided in Article NINTH hereof and, upon the approval or deemed
approval of such accounting, the Trustee shall transfer to the successor trustee
all of the assets then constituting the Trust Fund and the Trustee shall to the
maximum extent permitted by ERISA be forever released and discharged from all
liability and accountability with respect to the propriety of its acts and
transactions; provided, however, that

                                      -14-

<PAGE>   17

the Trustee may, in its sole discretion, transfer such assets prior to the
completion of such accounting if the Sponsor agrees thereto in writing, such
writing to include such limitations on the Trustee's liability therefor as the
Trustee may deem appropriate. The term "Trustee" as used in this Agreement shall
be deemed to apply to any successor trustee acting hereunder.

         THIRTEENTH: AMENDMENT

         An authorized officer of the Sponsor may amend all or any part of this
Agreement at any time provided, however, that any amendment shall not be
effective until the instrument of amendment has been agreed to and executed by
the Trustee. Any such amendment or modification of this Agreement may be
retroactive if necessary or appropriate to qualify or maintain the Trust Fund as
a part of a plan and trust exempt from federal income taxation under sections
401(a) and 501(a) of the Code, the provisions of ERISA, or any other applicable
provisions of federal or state law, as now in effect or hereafter amended or
adopted, and any regulations issued thereunder, including, without limitation,
any regulations issued by the United States Treasury Department, or the United
States Department of Labor.

         Notwithstanding anything contained in this Article THIRTEENTH to the
contrary, no amendment shall divert any part of the Trust Fund to, and no part
of the Trust Fund shall be used for, any purpose other than for the exclusive
purpose of providing benefits to Participants and their beneficiaries; provided,
however, that nothing in this Article THIRTEENTH shall be deemed to limit or
otherwise prevent the payment from the Trust Fund of expenses, other charges as
provided in Article ELEVENTH, or as otherwise permitted by the Plan.

         FOURTEENTH: TERMINATION.

         This Agreement and the Trust Fund hereby created may be terminated at
any time by the Board of Directors of the Sponsor by written notice delivered to
the Trustee. Upon receipt of such notice of termination, the Trustee shall,
after payment of all expenses incurred in the administration of the Trust Fund
and such compensation as the Trustee may be entitled to, and upon approval of
the appropriate governmental or quasi-governmental authorities (if such approval
shall be required under applicable law or desired by the Committee), then
distribute the Trust Fund in cash or in kind to such persons or entities,
including the Company, at such time and in such amounts as the Committee shall
direct, which direction shall be in conformity with the provisions of the Plan
and ERISA.

         FIFTEENTH: PLAN-TO-PLAN TRANSFERS; ROLLOVERS.

         The Trustee or its agent may transfer all of the property representing
a Participant's vested interest in the Plan to the trustees of any trust
qualified under section 401(a) of the Code or to an individual retirement
account. The Trustee or its agent may make such a transfer only at the direction
of the Committee.

         The Trustee may accept as part of the Trust Fund such property as is
acceptable to the Trustee that represents a Participant's retirement benefits
transferred from a trust qualified under

                                      -15-

<PAGE>   18

section 401(a) of the Code or transferred from the Participant or an individual
retirement account as a permissible rollover under section 402(c) or 408(d)(3)
of the Code. The Trustee may accept such a transfer only at the direction of the
Committee. A Participant shall at all times be fully vested in any property so
transferred as a rollover to the Trust Fund. Such property shall be distributed
to the Participant or his beneficiary at the direction of the Committee within
the time required for distribution of his or her retirement benefits under the
applicable provisions of the Plan.

         SIXTEENTH: ADOPTING EMPLOYERS.

         An affiliated entity of the Sponsor that has adopted the Plan in
accordance with its terms shall become a party to this Agreement by delivering
to the Sponsor and the Trustee a certified copy of a resolution of its board of
directors or governing body to the effect that it agrees to adopt the Plan, to
become a party to this Agreement, and to be bound by all the terms and
conditions of the Plan and this Agreement. The Sponsor shall have the sole
authority to enforce this Agreement on behalf of any such affiliated entity and
the Trustee shall in no event be required to deal with any such affiliated
entity except by dealing with the Company as its agent. Irrespective of the
number of affiliated entities which may become parties to this Agreement, the
Trustee shall in all respects invest and administer the Trust Fund as a single
fund for investment and accounting purposes without allocation of any part of
the Trust Fund as between the Sponsor and any such affiliated entity.

         An affiliated entity that has adopted the Plan shall cease to be a
party to this Agreement upon the Sponsor delivering to the Trustee a certified
copy of a resolution of such affiliated entity's board of directors or governing
body terminating its participation in the Plan. In such event, or in the event
of the merger, consolidation, sale of property or stock, separation,
reorganization or liquidation of the Sponsor or of any such affiliated entity,
or in the event of the establishment, modification or continuance of any other
retirement plan that separately or in conjunction with this Plan qualifies under
section 401(a) of the Code, the Trustee shall continue to hold the portion of
the Trust Fund that is attributable to the participation in the Plan of the
employees and their beneficiaries affected by such termination or by such
transaction, and this Agreement shall continue in force with respect to such
portion, until otherwise directed by the Committee, in accordance with the
provisions of the Plan and ERISA.

         SEVENTEENTH: ALIENATION.

         No interest in the Trust Fund shall be assignable or subject to
anticipation, sale, transfer, mortgage, pledge, charge, garnishment, attachment,
bankruptcy or encumbrance or levy of any kind, and the Trustee shall not
recognize any attempt to assign, sell, transfer, mortgage, pledge, charge,
garnish, attach or otherwise encumber the same except to the extent that such
attempt is made pursuant to a court order determined by the Committee to be a
qualified domestic relations order, as defined in section 414 of the Code and
section 206 of ERISA, or as otherwise required by law.

                                      -16-

<PAGE>   19

         EIGHTEENTH: BOND.

         The Trustee shall not be required to give any bond or any other
security for the faithful performance of its duties under this Agreement except
as required by law.

         NINETEENTH: SUCCESSORS.

         This Agreement shall be binding upon the respective successors and
assigns of the Company and the Trustee. Any corporation that shall, by merger,
consolidation, purchase or otherwise, succeed to substantially all the trust
business of the Trustee shall, upon such succession, and without any appointment
or other action by any person, be and become successor Trustee hereunder.

         TWENTIETH: SEVERABILITY.

         If any provision of this Agreement is held to be invalid, such
invalidity shall not affect the remaining provisions of the Agreement and they
shall be construed and enforced as if such invalid provisions had never been
inserted therein.

         TWENTY-FIRST: COMMUNICATIONS.

         Communications to the Sponsor or the Committee shall be addressed to
