made, entered into and adopted effective as of the 1st day of January, 1998, by
and between Corixa Corporation, a Delaware corporation, sometimes hereinafter

referred to as the "Trustee." The Plan and Trust set forth hereunder shall be
known as the CORIXA CORPORATION RETIREMENT SAVINGS PLAN AND TRUST (1998

                        NAME, EFFECTIVE DATE AND PURPOSE

SECTION 1.1 NAME OF PLAN; EFFECTIVE DATE.

        The Plan shall be known as the CORIXA CORPORATION RETIREMENT SAVINGS
PLAN (1998 Restatement). It may also be known as the CORIXA SAVINGS PLAN. This
Plan is a continuation in amended and restated form of the Corixa Corporation
Retirement Savings Plan, initially established effective as of January 1, 1995.
The effective date of this restatement is January 1, 1998, unless otherwise
provided for in the Plan. The rights of an Employee or Beneficiary with respect
to any period before January 1, 1998, or any other effective dates specified
herein, shall be governed by the corresponding provisions of the Plan in effect
as of the relevant period.

SECTION 1.2 PURPOSE.

        The Plan and Trust are created and maintained for the benefit of
Eligible Employees and their Beneficiaries to provide a supplement to retirement
income and to provide Eligible Employees with a means of supplementing their
retirement income on a tax-favored basis. The Plan is intended to qualify as a
profit-sharing plan and as a cash or deferred arrangement under sections 401(a),
401(k) and related sections of the Internal Revenue Code of 1986, as amended
(the "Code"), and includes matching Company contributions as described in Code
section 401(m). The Trust associated with the Plan is intended to qualify under
section 501(a) of the Code.

SECTION 1.3 EXCLUSIVE BENEFIT.

        This Plan was adopted and is maintained for the exclusive benefit of the
Participants and their Beneficiaries. This Plan shall be interpreted in a manner
consistent with this intent. No part of the principal or income of the Trust
Fund shall revert to the Company or any Affiliate or be used for any purpose
other than the exclusive benefit of Participants or their Beneficiaries, except
as provided in Sections 4.8.6 and 4.10.

SECTION 1.4 NO ENLARGEMENT OF EMPLOYMENT RIGHTS.

        Neither the establishment or maintenance of the Plan, the making of any
Company Contributions nor any action of the Company or the Administrative
Committee or the Trustee, shall be held or construed to confer upon any
individual any right to be retained in the services of the Company nor, upon
termination of service, any right or interest in the Trust Fund or other assets
of the Plan other than as provided under the terms of this Plan.

                (irrespective of whether the employment relationship has
                terminated) credited for the computation period during which an
                absence due to vacation, holiday, illness, incapacity (including
                disability), layoff, jury duty or leave of absence occurs; and

                        (3) on account of back pay awarded to an Employee or

                pertains, irrespective of mitigation of damages, and provided
                that such Employee receives no credit for the same hour under
                clause (1) or (2) above.

        Notwithstanding the preceding, no Hours of Service shall be credited for
        periods during which no duties are performed if payment by the Company
        is made or due under a plan maintained solely for the purpose of

        compensation or disability insurance laws, or is made as reimbursement

        established and uniformly administered personnel policies and not
        exceeding 12 full months, provided that the Employee returns to active
        employment within 30 days after the authorized absence period expires,
        and provided, further, that this subsection (b) shall apply only in the
        case of an absence if the Employee would thereby be prevented from
        incurring a Break in Service for any Plan Year. In no event shall more
        than 501 Hours of Service be credited on account of any single
        continuous period during which an Employee performs no duties by reason
        of an unpaid leave of absence as described in this subsection (b).

        Employment and Reemployment Rights act of 1994 ("USERRA"), or any

        for all persons in military service in the Armed Forces of the United
        States, as defined in USERRA, "Hour of Service" means each hour for
        which an Employee would have received payment from or performed duties

        Employee being discharged from such military service
<PAGE>   11

        such Employee applies for reemployment with the Company and takes all
        other necessary action to be entitled to, and to be otherwise eligible
        for, reemployment rights, as provided pursuant to USERRA, or any similar
        law from time to time in force. Notwithstanding any provision of this
        Plan to the contrary, contributions, benefits and service credit with
        respect to qualified military service will be provided in accordance
        with Code section 414(u).

        determining whether a Break in Service has occurred, in the case of an
        Employee who is absent from active employment with the Company for any
        period, (A) by reason of pregnancy or the birth of his or her child, (B)
        by reason of the placement of a child with the Employee in connection
        with his or her adoption of such child, or (C) for purposes of caring
        for any such child for a period beginning immediately following such
        birth or placement, the following rules shall apply:

                        (1) "Hour of Service" means each hour which is not
                credited as an Hour of Service under subsections (a) or (b) but
                which would otherwise normally have been credited to such
                individual (but for such absence) under subsections (a) or (b).

                        (2) In any case in which the Company is unable to
                determine the number of hours which would otherwise normally
                have been credited to such Employee (but for such absence), such
                individual shall be credited with 8 Hours of Service for each
                day of such absence.

                        (3) Notwithstanding the foregoing, no more than 501
                Hours of Service shall be credited under this subsection (c) to
                any individual on account of any single pregnancy, birth or
                placement, and the hours described in this subsection (c) shall
                be treated as Hours of Service (A) only for the Plan Year in
                which the absence from active employment begins, if the Employee
                would thereby be prevented from incurring a Break in Service in
                such Plan Year, or (B) in any other case, in the next following
                Plan Year.

Participant Elective Deferral Contributions and earnings thereon in accordance
with Section 6.3.1. The salary deferral election made by a Participant shall
become effective with respect to the first payroll period ending on or after
such election is executed and delivered to the Company, or as soon as
administratively feasible thereafter, and shall remain in effect until the
election is modified or canceled by the Participant or the Committee as
hereinafter provided, or until the Participant ceases to be an Eligible
Employee, becomes a Suspended Participant because of a hardship withdrawal (if
permitted), or his or her participation terminates.

        4.1.4 Cancellation or Modification of Salary Deferral Election. A
Participant may cancel his or her salary deferral with respect to Participant
Elective Deferral Contributions at any time, by executing and delivering to the
Company such form and with such advance notice as the Committee shall specify. A
Participant may modify his or her salary deferral election with respect to
Participant Elective Deferral Contributions once each calendar quarter, by
executing and delivering a new salary deferral election to the Company, on such
form and with such advance notice as the Committee shall specify. The
Participant's cancellation or modification of his or her salary deferral
election shall become effective with respect to the first payroll period ending
on or after the appropriate form is executed and delivered to the Company, or as
soon as administratively feasible thereafter.

        4.1.5 Suspension of Participant Elective Deferral Contributions.
Notwithstanding any contrary salary deferral election, no portion of a Suspended
Participant's Compensation for any payroll period which begins during the first
12 months of a period of suspension shall be subject to such election nor
contributed under the Plan as Participant Elective Deferral Contributions.

        4.1.6 Time for Company Contribution of Participant Elective Deferral
Contributions to the Trust. Participant Elective Deferral Contributions for each
payroll period shall be paid to the Trust as soon as such amounts can reasonably
be segregated from the Company's general assets after the end of the payroll
period with respect to which they would otherwise have been paid to the
Participant, but in no event later than 15 business days after end of the month
in which such amounts are withheld from the Participant's Compensation.

SECTION 4.2 COMPANY MATCHING CONTRIBUTIONS.

        4.2.1 Company Determination of Matching Contributions. The Company, in
its discretion, may determine that the Company shall make Company Matching
Contributions to the Trust. The Company may select, each Plan Year, the amount
or percentage (up to 100%) of the Participant Elective Deferral Contributions on
which to base the Company Matching Contributions, and the percentage or other
formula for the Company Matching Contributions to be applied equally to all
Participants in proportion to their Participant Elective Deferral Contributions
and to be allocated to Participant's Company Matching Contributions Account.
Such Company Matching Contributions shall be subject to the rules and
limitations provided in this Article 4.

        4.2.2 Allocation of Matching Contributions. The Company Matching
Contributions to be made with respect to a Participant on account of his or her
Participant Elective Deferral Contributions for the Plan Year shall be allocated
to his or her Company Matching Account as of the last day of each calendar
quarter in accordance with the formula determined by the Company for making such
contributions, regardless of whether such Participant is an Eligible Employee as
of such date.

        4.2.3 Forfeiture of Matching Contributions. Notwithstanding the
allocation to a Participant's Company Matching Account described in Section
4.2.2, Company Matching Contributions shall be subject to forfeiture to the
extent they are allocated to a Participant's Account based on Participant
Elective Deferral Contributions that are determined to be in excess of the limit
described in Section 4.7.1 and distributed in accordance therewith, or to the
extent they are allocated based on Participant Elective Deferral Contributions
that are determined to be Excess ADP Contributions under Section 4.7.2 and
distributed in accordance therewith, or to the extent such Company Matching
Contributions are determined to be Excess ACP Contributions under Section 4.7.3
and distributed in accordance therewith, or to the extent the Participant is not
vested in such Company Matching Contributions allocated to his or her account
upon termination of such Participant's employment as provided under Article 5.
Such forfeitures shall be used in accordance with Section 4.5.1.
<PAGE>   21

SECTION 4.3 COMPANY QUALIFIED NONELECTIVE CONTRIBUTIONS.

        The Company shall contribute to the Trust for any Plan Year the amount
(if any) that is determined by the Company, in its discretion, as Company
Qualified Nonelective Contributions. The amount of Company Qualified Nonelective
Contributions for the Plan Year shall be determined in a duly authorized action
of the Company, which may specify a dollar amount or may set forth a definite
formula for computing the amount. Company Qualified Nonelective Contributions
shall be allocated as of the end of the Plan Year among the Company QNC Accounts
of Non-Highly Compensated Employees in the proportion that the Compensation of
such Participants bears to the aggregate Compensation paid by the Company to all
such Participants in the Plan Year.

SECTION 4.4 COMPANY PROFIT-SHARING CONTRIBUTIONS.

        4.4.1 Company Determination of Profit-Sharing Contributions. The Company
shall contribute to the Trust for any Plan Year the amount, if any, that is
determined by the Company, in its discretion, as Company Profit-Sharing
Contributions. The amount of Company Profit-Sharing Contributions for the Plan
Year, if any, shall be determined in a duly authorized action of the Company,
which may specify a dollar amount or may set forth a definite formula for
computing the amount. Company Profit-Sharing Contributions to the Plan for any
Plan Year may be made without regard to current or accumulated earnings or
profits of the Company for the taxable year or years ending with or within such
Plan Year. Notwithstanding the preceding sentence, the Plan is intended to
qualify as a profit-sharing plan for purposes of Code sections 401(a), 402, 412
and 417.

        4.4.2 Allocation of Company Profit-Sharing Contributions. Company
Profit-Sharing Contributions, if any, shall be allocated, as of the last day of
the Plan Year, among the Company Profit-Sharing Accounts of (A) Participants who
completed at least 1000 Hours of Service as an Eligible Employee during such
Plan Year and are Eligible Employees as of the last day of such plan Year; and
(B) Participants whose Service terminated at any time during the Plan Year by
reason of retirement at or after Normal Retirement Age, death or Disability, in
the proportion that the Compensation of such Participants bears to the aggregate
Compensation paid by the Company to all such Participants in the Plan Year.

        4.4.3 Forfeiture of Company Profit-Sharing Contributions.
Notwithstanding the allocation to a Participant's Company Profit-Sharing Account
described in Section 4.4.2, Company Profit-Sharing Contributions shall be
subject to forfeiture to the extent the Participant is not vested in such
Company Profit-Sharing Contributions upon termination of such Participant's
Service as provided under Article 5. Such forfeitures shall be used in
accordance with Section 4.5.1.

SECTION 4.5 USE OF FORFEITURES; COMPANY FORFEITURE RESTORATION CONTRIBUTION.

        4.5.1 Use of Forfeited Company Matching Contribution and Forfeited
Company Profit-Sharing Contributions. Any Company Matching Contributions or
Company Profit-Sharing Contributions that are forfeited for any reason shall be
used first to accomplish any restoration of the previously forfeited portion of
a former Employee's Company Matching Account and Company
<PAGE>   22

Profit-Sharing Account as required under the provisions of Section 5.6. Any
remaining forfeited Company Matching Contributions or Company Profit-Sharing
Contributions shall be used to reduce any Company Matching Contributions,
Company Qualified Nonelective Contributions and Company Profit-Sharing
Contributions, in that order, that would otherwise be made by the Company for
the Plan Year. If any forfeited Company Matching Contributions or Company
Profit-Sharing Contributions cannot be allocated because the limits of Code
section 415 would thereby be exceeded, such forfeited Company Matching
Contributions or Company Profit-Sharing Contributions shall be allocated to a
suspense account and shall be used in the next Plan Year and succeeding Years,
in order of time until the suspense account is exhausted, in the manner and
order described in herein as if such amounts had been forfeited in such next or
succeeding Plan Year.

        4.5.2 Company Forfeiture Restoration Contributions. For any Plan Year in
which a restoration of the previously forfeited portion of a former Employee's
Company Matching Account or Company Profit-Sharing Account is required under the
provisions of Section 5.6 and the forfeitures for that Plan Year under Section
4.2.3 and Section 5.6 to be used in accordance with Section 4.5.1 are
insufficient to accomplish such restoration, the Company Matching Contributions
and/or Company Profit-Sharing Contributions for the Plan Year, as applicable,
shall include an amount necessary to cover such restoration.

SECTION 4.6 ROLLOVER CONTRIBUTIONS.

        4.6.1 The Committee may direct the Trustee to accept a transfer to the
Trust Fund of an eligible rollover distribution within the meaning of Code
section 402(c) or a rollover contribution within the meaning of Code section
408(d)(3)(A)(ii) to be allocated to the Participant's Rollover Account. The
Committee shall determine, in its sole discretion, whether a transfer meets the
requirements of this Section 4.6.

        4.6.1 Rollover Contributions shall not be taken into account in
determining the allocations and limitations under Section 4.8.

        4.6.2 The Committee may not direct the Trustee to accept a transfer to
the Trust from the trustee or custodian of another plan pursuant to this Section
4.6 if such transfer would cause the Plan to become a Transferee Plan. A
"Transferee Plan" for purposes of this Section 4.6.2 is a plan which receives a
direct or indirect transfer of assets from the trustee or custodian of a plan
which is a defined benefit plan, money purchase plan, or other plan which is
required to provide automatic survivor benefits pursuant to Code section
401(a)(11), and shall also include any plan which itself receives a direct or
indirect transfer of assets from a Transferee Plan.

        4.6.3 Assets transferred to the Trust Fund pursuant to this Section 4.6
shall be credited to the Participant's Rollover Account. A Participant's
interest in his or her Rollover Account shall be 100% vested and nonforfeitable
at all times.

        4.6.4 If it is later determined that an amount transferred to the Trust
Fund pursuant to this Section 4.6 did not in fact qualify as an eligible
rollover distribution under Code section 402(c) or a rollover contribution under
Code 408(d)(3)(A)(ii), then the balance credited to the Participant's
<PAGE>   23

Rollover Account shall immediately be (A) segregated from all other Plan assets,
(B) treated as a nonqualified trust established by and for the benefit of the
Participant, and (C) distributed to the Participant. Such a nonqualifying
rollover shall be deemed never to have been a part of the Trust Fund.

        4.6.5 A Participant's Rollover Account shall be distributed at the times
and in the manner set forth in Article 8 for his or her Account.

SECTION 4.7 CODE SECTION 402(g), 401(k) AND 401(m) LIMITATIONS ON CONTRIBUTIONS;
CORRECTIVE DISTRIBUTIONS.

        4.7.1 Code Section 402(g) Limitation on Participant Elective Deferral
Contributions; Corrective Distribution of Excess Elective Deferrals. The
aggregate Participant Elective Deferral Contributions for each calendar year
made on behalf of any Participant, together with his or her before-tax elective
deferrals under any other plan or arrangement subject to Code section 402(g)
that is maintained by the Company or an Affiliate, shall not exceed $7,000, as
adjusted for cost of living increases in accordance with Code section 402(g)(5),
(the "Code Section 402(g) Limit").

                (a) Suspension of Participant Elective Deferral Contributions.
        The Committee may suspend or limit Participant Elective Deferral
        Contributions to be made on behalf of any Participant at any time in
        order to prevent the actual or estimated cumulative amount of such
        Participant Elective Deferral Contributions together with his or her
        before-tax elective deferrals under any other plan or arrangement for
        any calendar year from exceeding the Code Section 402(g) Limit.

                (b) Participant Designation of Excess Elective Deferrals;
        Distribution. A Participant who has made before-tax elective deferrals
        in excess of the Code Section 402(g) Limit, under this Plan or under
        this Plan and one or more other salary deferral plans ("Excess Elective
        Deferrals"), may give written notice to the Committee specifying the
        amount that he or she has allocated to this Plan for the preceding
        calendar year as Excess Elective Deferrals. Such notice must be given no
        later than March 1 of the year following the calendar year to which it
        relates. The amount of such Excess Elective Deferrals (together with the
        income allocable thereto) shall be distributed to the Participant no
        later than April 15 (to the extent practicable) of the year in which the
        Participant gives notice.

                (c) Excess Elective Deferrals in the Absence of Participant
        Designation; Distribution. If the Committee determines that a
        Participant has made pre-tax elective deferrals under one or more other
        salary deferral plans subject to Code section 401(k) but the Participant
        does not give the notice described in Section 4.7.1(b), to the extent
        the Participant has made Excess Elective Deferrals, such Excess Elective
        Deferrals shall be deemed to have been made under this Plan and shall be
        distributed, together with the income attributable thereto, no later
        than the April 15 (to the extent practicable) following the calendar
        year for which the deferral was made.
<PAGE>   24

                (d) Coordination with Excess ADP Contributions. Excess Elective
        Deferrals to be distributed under this Section 4.7.1 for a taxable year
        shall be reduced by any Excess ADP Contributions previously distributed
        with respect to the Participant for the Plan Year beginning with or
        within such taxable year.

                (e) Timing of Income Treatment for Distributed Excess Elective
        Deferrals. Any Excess Elective Deferrals distributed on or before April
        15 of the calendar year following the year to which such Excess Elective
        Deferrals relate are includible in the Participant's gross income for
        the taxable year in which such amounts were withheld from the
        Participant's Compensation. Any Excess Elective Deferrals distributed
        after April 15 of the calendar year following the year to which such
        Excess Elective Deferrals relate are includible in the Participant's
        gross income for the taxable year distributed.

        4.7.2 Code Section 401(k) Actual Deferral Percentage Limitation;
Corrective Distribution of Excess ADP Contributions.

                (a) Maximum Allowable ADP. In no event shall the actual deferral
        percentage (the "ADP") for any Plan Year for the Participants who are
        Highly Compensated Employees (the "HCEs") exceed the "Maximum Allowable
        ADP," determined by reference to the ADP for the preceding Plan Year for
        the Participants who are Non-Highly Compensated Employees (the "NHCEs")
        using the following table:

<TABLE>
              <S>                          <C>
                  If the ADP for            The Maximum Allowable
                  the NHCEs is:             ADP for HCEs is:

                  Less than 2%              2.0 x ADP for NHCEs
                  2% to 8%                  ADP for NHCEs + 2%
                  More than 8%              1.25 x ADP for NHCEs
</TABLE>
                (b) Actual Deferral Percentage. The ADP for a group of
        Participants for a Plan Year is the average of the actual deferral
        ratios (calculated separately for each Participant in the group). The
        actual deferral ratio for a Participant shall be determined by dividing
        (A) the total of all ADP Contributions (as defined in Section 4.7.2(c))
        made on behalf of the Participant for the Plan Year by (B) the
        Participant's Compensation for the Plan Year. In computing the actual
        deferral ratio for each Participant, the following special rules shall
        apply:

                        (1) ADP Contributions will be taken into account in
                determining the ADP for a Plan Year only if they relate to
                Compensation that either would have been received by the
                Employee in the Plan Year (but for the deferral election) or are
                attributable to services performed by the Employee in the Plan
                Year and would have been received by the Employee within 2-1/2
                months after the close of the Plan Year (but for the deferral
                election). In the case of a Participant on whose behalf no ADP
                Contributions are made for the Plan Year (except those not taken
                into account
<PAGE>   25

                pursuant to the preceding sentence) the actual deferral ratio
                for such Participant that is to be included in determining the
                ADP is zero.

                        (2) An HCE's actual deferral ratio shall be determined
                by treating all cash or deferred arrangements maintained by the
                Company or any Affiliated Entities as part of this Plan;
                provided, however, that if an HCE participates in two or more
                cash or deferred arrangements that have different plan years,
                this aggregation rule shall be applied by treating all such cash
                or deferred arrangements with plan years ending with or within
                the same calendar year as a single arrangement.

                        (3) If the Company or an Affiliate maintains any other
                plan that is aggregated with this Plan for purposes of applying
                Code sections 401(a)(4) and 410(b), then any cash or deferred
                arrangement included in such plan shall be treated as part of
                this Plan for purposes of determining the ADP. Contributions to
                a plan or portion of a plan that constitutes an employee stock
                ownership plan within the meaning of Code section 4975(e)(7)
                shall not be taken into account in determining the ADP. Plans
                shall be aggregated under the rules set forth in this subsection
                only if they have the same plan year.

                (c) ADP Contributions. ADP Contributions shall include
        Participant Elective Deferral Contributions and, at the election of the
        Committee, Company Qualified Nonelective Contributions, provided that,
        with respect to Company Qualified Nonelective Contributions:

                        (1) such contributions, alone and together with Company
                Qualified Nonelective Contributions not included in determining
                the ADP, satisfy the requirements of Code section 401(a)(4); and

                        (2) the effect of including such Company Qualified
                Nonelective Contributions in determining the ADP does not
                increase the difference between the ADP for the HCEs and the ADP
                for NHCEs.

                (d) Potential Excess ADP Contributions. In the event that (but
        for the application of this Section 4.7.2(d)) the Committee determines
        that the ADP for the Participants who are HCEs would exceed the Maximum
        Allowable ADP for HCEs permitted under Section 4.7.2(a) for a Plan Year,
        the Committee in its discretion may reduce the amount or percentage of
        Salary Deferral Contributions to be made subsequently on behalf of the
        HCEs by such amount or percentage as, and for as long as, the Committee
        in its discretion may determine is necessary or appropriate in the
        circumstances then prevailing to assure that the Maximum Allowable ADP
        will not be exceeded.

                (e) Actual Excess ADP Contributions; Return of Excess. "Excess
        ADP Contributions," which are "excess contributions" within the meaning
        of Code section 401(k)(8)(B), shall occur if the ADP for the HCEs
        exceeds the Maximum Allowable ADP for the HCEs for a Plan Year. Excess
        ADP Contributions, together with any income
<PAGE>   26

        allocable thereto and reduced by any loss allocable thereto (determined
        as provided below), contributed on behalf of the HCEs shall be
        distributed to the HCEs within 2-1/2 months after the close of the Plan
        Year for which they were made to the extent practicable, and in any
        event before the close of the Plan Year that next follows the Plan Year
        to which such excess contributions relate, or, in the event of
        termination of the Plan, within 12 months after the termination of the
        Plan. Notwithstanding the provisions of Article 8, no consent of the
        Participant or his or her spouse shall be required for the distribution
        of Excess ADP Contributions in accordance with this Section 4.7.2(e). In
        determining the distribution under this Section 4.7.2(e), the following
        rules shall apply:

                        (1) The amount to be distributed to each HCE shall be
                determined on the basis of the amount of ADP Contributions made
                on behalf of such HCE in accordance with Code section
                401(k)(8)(B) and (C) and the regulations thereunder.

                        (2) The income or loss allocable to such Excess ADP
                Contributions for the Plan Year shall be determined by
                multiplying the income for the Plan Year allocable to ADP
                Contributions by a fraction, the numerator of which is the
                Excess ADP Contributions of the Participant for the Plan Year
                and the denominator of which is the portion of the Participant's
                Account balance attributable to ADP Contributions as of the end
                of the Plan Year, reduced by the gain allocable to such amount
                for the Plan Year and increased by the loss allocable to such
                amount for the Plan Year. The income or loss allocable to such
                Excess ADP Contributions for the period between the end of the
                Plan Year and the date of distribution shall be equal to 10% of
                the income allocable to Excess ADP Contributions for the Plan
                Year multiplied by the number of calendar months that have
                elapsed since the end of the Plan Year. For purposes of
                determining the number of calendar months, a distribution
                occurring on or before the 15th day of the month shall be
                treated as having been made on the last day of the preceding
                month, and a distribution occurring after such 15th day shall be
                treated as having been made on the first day of the next month.

                        (3) Excess ADP Contributions to be distributed under
                this Section with respect to an Employee for a Plan Year shall
                be reduced by any Excess Elective Deferrals previously
                distributed to such Employee for his or her taxable year ending
                with or within such Plan Year.

        4.7.3 Code Section 401(m) Actual Contribution Percentage Limitation;
Corrective Distribution of Excess Aggregate ACP Contributions.

                (a) Maximum Allowable ACP. In no event shall the actual
        contribution percentage (the "ACP") for any Plan Year for the HCEs
        exceed the "Maximum Allowable ACP," as determined by reference to the
        ACP for the preceding Plan Year for NHCEs using the following table:
<TABLE>
               <S>                        <C>
                  If the ACP for            The Maximum Allowable
                  the NHCEs is:             ACP for HCEs is:
</TABLE>
<PAGE>   27
<TABLE>
           <S>                            <C>
                  Less than 2%              2.0 x ACP for NHCEs
                  2% to 8%                  ACP for NHCEs + 2%
                  More than 8%              1.25 x ACP for NHCEs
</TABLE>
                (b) Actual Contribution Percentage. The ACP for a group of
        Participants for a Plan Year is the average of the actual contribution
        ratios (calculated separately for each Participant in the group). The
        ACP shall be determined after determination of Excess Elective Deferrals
        (under Section 4.7.1), determination of the Excess ADP Contributions
        (under Section 4.7.2) and after any forfeiture of Company Matching
        Contributions under Section 4.2.3. The actual contribution ratio for a
        Participant shall be determined by dividing (A) the total of all ACP
        Contributions (as defined in Section 4.7.2(c)) made on behalf of the
        Participant for the Plan Year by (B) the Participant's Compensation for
        the Plan Year. In computing the actual contribution ratio for each
        Participant, the following special rules shall apply:

                        (1) Matching Contributions will be taken into account in
                determining the ACP for a Plan Year only if they are made on
                account of the Participant's Elective Deferral Contributions for
                the Plan Year and not forfeited under Section 4.2.3. In the case
                of a Participant on whose behalf no ACP Contributions are made
                for the Plan Year (except those not taken into account pursuant
                to the preceding sentences) the actual contribution ratio for
                such Participant that is to be included in determining the ACP
                is zero.

                        (2) An HCE's actual contribution ratio shall be
                determined by treating all matching contributions (within the
                meaning of Code section 401(m)(4)(A)) made on behalf of such HCE
                and all after-tax employee contributions made by such HCE to
                plans maintained by the Company or any Affiliated Entities as
                contributed to this Plan.

                        (3) If the Company or an Affiliate maintains any other
                qualified plan to which are made matching contributions (within
                the meaning of Code section 401(m)(4)(A)), elective deferrals
                (within the meaning of Code section 401(m)(4)(B)) or employee
                contributions, and that plan is aggregated with this Plan for
                purposes of applying Code sections 401(a)(4) and 410(b), then
                all such plans shall be treated as part of this Plan for
                purposes of determining the ACP. Contributions to a plan or
                portion of a plan that constitutes an employee stock ownership
                plan within the meaning of Code section 4975(e)(7) shall not be
                taken into account in determining the ACP. Plans shall be
                aggregated under the rules set forth in this subsection only if
                they have the same plan year.

                (c) ACP Contributions. ACP Contributions shall include Company
        Matching Contributions and, at the election of the Committee, Qualified
        Nonelective Contributions and Participant Elective Deferral
        Contributions, subject to the following rules:
<PAGE>   28

                        (1) Qualified Nonelective Contributions allocated to
                Participants' Accounts for a Plan Year may be included in
                determining the ACP provided that

                                (A) such contributions, alone and together with
                        Qualified Nonelective Contributions not included in
                        determining the ACP, satisfy the requirements of Code
                        section 401(a)(4); and

                                (B) the effect of including such Qualified
                        Nonelective Contributions in determining the ACP does
                        not increase the difference between the ACP for the HCEs
                        and the ACP for NHCEs.

                        (2) Participant Elective Deferral Contributions
                allocated to Participants' Accounts for a Plan Year may be
                included in determining the ACP provided that

                                (A) such contributions, alone and together with
                        Participant Elective Deferral Contributions not included
                        in determining the ACP, satisfy the requirements of Code
                        section 401(k)(3); and

                                (B) such contributions are not taken into
                        account in determining the ADP.

                (d) Potential Excess ACP Contributions. In the event that (but
        for the application of this Section 4.7.3(d)) the Committee determines
        that the ACP for the Participants who are HCEs would exceed the Maximum
        Allowable ACP for HCEs permitted under Section 4.7.3(a) for a Plan Year,
        the Committee in its discretion may reduce the amount of ACP
        Contributions subsequently to be contributed on behalf of the HCEs by
        such amount as, and for as long as, the Committee in its discretion may
        determine is necessary or appropriate in the circumstances then
        prevailing to assure that the Maximum Allowable ACP will not be
        exceeded.

                (e) Actual Excess ACP Contributions; Return of Excess. "Excess
        Aggregate ACP Contributions," which are "excess aggregate contributions"
        within the meaning of Code section 401(m)(6)(B), shall occur if the ACP
        for the HCEs exceeds the Maximum Allowable ACP for the HCEs for a Plan
        Year. Excess Aggregate ACP Contributions, together with any income
        allocable thereto and reduced by any loss allocable thereto (determined
        as provided below), contributed on behalf of the HCEs shall be
        distributed to the within 2-1/2 months after the close of the Plan Year
        for which they were made to the extent practicable, and in any event
        within 12 months of the close of the following Plan Year, or, in the
        event of termination of the Plan, within 12 months after the termination
        of the Plan. Notwithstanding the provisions of Article 8, no consent of
        the Participant or his or her spouse shall be required for the
        distribution of Excess Aggregate ACP Contributions in accordance with
        this Section 4.7.3(e).
<PAGE>   29

                        (1) The amount to be distributed to each HCE shall be
                determined on the basis of the amount of ACP Contributions made
                on behalf of such HCE in accordance with Code section
                401(m)(6)(B) and (C) and the regulations thereunder.

                        (2) The income or loss allocable to such Excess
                Aggregate ACP Contributions for the Plan Year shall be
                determined by multiplying the income for the Plan Year allocable
                to ACP Contributions by a fraction, the numerator of which is
                the Excess Aggregate ACP Contributions of the Participant for
                the Plan Year and the denominator of which is the portion of the
                Participant's Account balance attributable to ACP Contributions
                as of the end of the Plan Year, reduced by the gain allocable to
                such amount for the Plan Year and increased by the loss
                allocable to such amount for the Plan Year. The income or loss
                allocable to such Excess Aggregate ACP Contributions for the
                period between the end of the Plan Year and the date of
                distribution shall be equal to 10% of the income allocable to
                Excess Aggregate ACP Contributions for the Plan Year multiplied
                by the number of calendar months that have elapsed since the end
                of the Plan Year. For purposes of determining the number of
                calendar months, a distribution occurring on or before the 15th
                day of the month shall be treated as having been made on the
                last day of the preceding month, and a distribution occurring
                after such 15th day shall be treated as having been made on the
                first day of the next month.

        4.7.4 Prohibition on Multiple Use of Maximum ADP and ACP.
Notwithstanding any contrary provision of this Plan, the multiple use of the
alternative methods of compliance with Code sections 401(k) and 401(m) contained
in Code sections 401(k)(3)(A)(ii)(II) and 401(m)(2)(A)(ii) shall not be
permitted. The provisions of Treasury Regulation section 1.401(m)-2(b), and any
supplementing or superseding regulation, are incorporated for this purpose.
Multiple use occurs if, after corrective distributions required under Sections
4.7.2 and 4.7.3 have been made, the sum of the ADP and the ACP for the HCEs
exceeds 1.25 times the greater of the ADP or the ACP of the NHCEs, plus the
lesser of (A) 2% plus the lesser of the ADP or ACP of the NHCEs, or (B) 200% of
the lesser of the ADP or ACP of the NHCEs. In the event that multiple use
occurs, it shall be corrected by reducing the ACP for HCEs, and treating such
reduction as an Excess Aggregate ACP Contribution under Section 4.4.7.

        4.7.5 Incorporation of Regulations by Reference. The provisions of
Sections 4.7.1 through 4.7.4 are intended to satisfy the requirements of Code
section 401(k)(3) and 401(m), respectively. The provisions of Code section
401(k)(3) and 401(m) and of Treasury Regulation sections 1.401(k)-1, 1.401(m)-1
and 1.401(m)-2 are incorporated herein by reference.

        4.7.6 Company Maintenance of Records. The Company shall maintain such
records as are necessary to demonstrate compliance with the applicable rules of
Code sections 401(k)(3) and 401(m) and the regulations thereunder. Such records
shall be sufficient to demonstrate satisfaction of the ADP and ACP Limitations.

SECTION 4.8 CODE SECTION 415 LIMITATIONS ON CONTRIBUTIONS.

        4.8.1 Annual Addition Limitation. Notwithstanding any contrary Plan
provision, in no event shall the Annual Addition to any Participant's Account
for any Limitation Year exceed the lesser of (A) $30,000 as adjusted for cost of
living increases in accordance with Code section 415(d)(1), or (B) 25% of the
Participant's Compensation (as defined in Section 4.8.4(c) below) for the
Limitation Year.

        4.8.2 Coordination With Other Defined Contribution Plans. If any
Participant participates both in this Plan and one or more defined contribution
plans or a welfare benefits fund (as defined in Code section 419(e)) maintained
by the Company or an Affiliate for the same Limitation Year, the Annual
Additions which may be credited to such Participant's Account under this Plan
for any such Limitation Year shall not exceed the limitation set forth in
Section 4.8.1 reduced by the Annual Additions credited to such Participant's
account under such other defined contribution plans or welfare benefits fund for
the Limitation Year. The amount credited to such Participant's accounts under
such other defined contribution plans or welfare benefits fund shall be reduced
under the provisions of such other plans or fund to the extent permitted before
any reduction of excess Annual Addition is made under Section 4.8.5.

        4.8.3 Coordination With Defined Benefit Plans. For Plan Years beginning
prior to January 1, 2000, if any Participant participates in both the Plan and
one or more defined benefit plans maintained by the Company or an Affiliate for
the same Limitation Year, then allocations to such Participant's Account shall
be subject to the limitation set forth in Code section 415(e), as modified by
Code section 416(h).

        4.8.4 Definitions. For purposes of this Section 4.8, the following
definitions shall apply:

                (a) "Aggregated Plan" means any defined contribution Plan
        (terminated or not) maintained by the Company or an Affiliate, provided
        that in applying the limitations of this Section 4.8 the special
        limitation applicable to employee stock ownership plans under Code
        section 415(c)(6) shall be taken into account with respect to a
        Participant who participates in any such plan.

                (b) "Annual Addition" means with respect to each Participant the
        sum for a Limitation Year of

                        (1) the share of all Participant Elective Deferral
                Contributions, Company Contributions and forfeitures allocated
                to the Participant's Account under this Plan (excluding
                allocations to restore a previously forfeited amount) plus any
                excess deferrals determined under Section 4.7.1, any Excess ADP
                Contributions determined under Section 4.7.2, and any Excess
                Aggregate ACP Contributions determined under Section 4.7.3;

                        (2) the share of all contributions made by the Company
                and all Affiliated Entities (including salary reduction
                contributions made pursuant to Code section
<PAGE>   31

                401(k) and any forfeitures) to be credited to the Participant's
                account under any Aggregated Plan;

                        (3) any nondeductible voluntary employee contributions
                under any Aggregated Plan;

                        (4) any amount allocated to the Participant's individual
                medical account (within the meaning of Code section 415(l))
                under a defined benefit plan maintained by the Company or any
                Affiliate; and

                        (5) any amount attributable to post-retirement medical
                benefits which is allocated to the Participant's separate
                account under a welfare benefits fund (within the meaning of
                Code section 419(e)) maintained by the Company or an Affiliate,
                if such amount is derived from contributions to the welfare
                benefits fund paid or accrued by the Company or an Affiliate
                after December 31, 1985; provided, however, that the limitation
                in Section 4.8.1 shall not apply to any contribution described
                in this clause (5) which is made after the Participant has
                separated from service with the Company and all Affiliated
                Entities.

        Rollover Contributions made pursuant to Section 4.6 shall not be
        considered in determining the amount of Annual Addition made with
        respect to a Participant.

                (c) "Compensation" means all Compensation as defined in Section
        2.1.13 plus any remuneration received by the Employee for services
        performed for an Affiliate; provided, however, that for any Plan Year
        beginning before January 1, 1998, Compensation for purposes of this
        Section 4.8 shall be reduced by the Participant's Elective Deferral
        Contributions under the Plan, any other elective deferral (as defined in
        Code section 402(g)(3)), and any elective salary reduction contributions
        made to a plan described in Code Section 125 and not includible in the
        Employee's gross income.

        4.8.5 Reduction of Excess Annual Addition. If any of the limitations
specified in Section 4.8.1 are exceeded with respect to any Participant for a
Limitation Year, then the amount of the excess Profit-Sharing Contribution,
Qualified Nonelective Contribution and/or Matching Contribution, in that order,
allocated to the Participant's Account shall be allocated to a Company
Contributions suspense account, and the balance credited to such account shall
be used to reduce the Company Matching Contributions, Company Qualified
Nonelective Contributions, and Company Profit-Sharing Contributions and the, in
that order, in the succeeding Plan Year or Years in order of time until the
suspense account is exhausted.

        4.8.6 Allocation of Suspense Account Balance. Any suspense account
created under Sections 4.5.1 or 4.8.5 above shall not share in the allocations
of income and realized or unrealized gains and/or losses of the Trust Fund. For
any year in which a suspense account created under Sections 4.5.1 or 4.8.5 is in
existence other than the Plan Year with respect to which such suspense account
was created, all amounts in such suspense account must be allocated and
reallocated to Participants' Accounts (subject to the limitations of Section
4.8.1) before any Company
<PAGE>   32

Contributions may be made in accordance with Sections 4.2, 4.3 or 4.4. In the
event the Plan is terminated, any amounts credited to any such suspense account
shall be returned to the Company.

SECTION 4.9 TOP-HEAVY PROVISIONS.

        The following provisions of the Plan shall be effective for any Plan
Year in which the Plan is a Top-Heavy Plan:

        4.9.1 Minimum Benefit Allocation for Top-Heavy Plan Years. For any Plan
Year in which the Plan is a Top-Heavy Plan, the amount of the aggregate
allocation of Company Profit-Sharing Contributions and Company Qualified
Nonelective Contributions to the Account of each Participant who is both an
Eligible Employee as of the last day of the Plan Year and a Non-Key Employee
shall be no less than the Minimum Benefit Allocation, regardless of his or her
Hours of Service.

        4.9.2 "Minimum Benefit Allocation" Except as provided in Section 4.9.3,
for purposes of this Section, the "Minimum Benefit Allocation" for each eligible
Non-Key Employee shall be the lesser of:

                (a) 3% of the Participant's Compensation; or

                (b) the same percentage of his or her Compensation as the
        highest percentage of Compensation allocated for the Plan Year to a Key
        Employee.

For purposes of determining whether the allocations to Non-Key Employees meet
the Minimum Benefit Allocation, in determining the amount of allocations to an
Employee's Account, Elective Deferral Contributions of a Key Employee shall be
taken into account.

        4.9.3 Top-Heavy Minimum Benefit Allocation for Participant Covered By
Defined Benefit Plan. For any Non-Key Employee who is a Participant in this Plan
and who is also covered by a defined benefit plan maintained by the Company or
any Affiliate (including a terminated or frozen defined benefit plan which must
be taken into account under Treasury Regulation section 1.416-1, T-4 and T-5),
the following rules shall apply:

                (a) The Minimum Benefit Allocation for any such Participant who
        receives the "defined benefit minimum" under the defined benefit plan
        (as defined in Treasury Regulation section 1.416-1, M-2), shall be zero.

                (b) The Minimum Benefit Allocation for any other such
        Participant shall be 5% of the Participant's Compensation.

                (c) Notwithstanding the foregoing, the Company may increase the
        Minimum Benefit Allocation for each such Participant to 7 1/2% of the
        Participant's Compensation for the Plan Year, if necessary in order to
        permit use of a factor of 1.25 in computing the
<PAGE>   33

        denominators of the defined benefit fraction and the defined
        contribution fraction under Code section 415(c) as modified by Code
        section 416(h).

        4.9.4 Minimum Benefit Contribution for Top-Heavy Years. If the aggregate
amount of Company Matching Contributions under Section 4.2, Company
Profit-Sharing Contributions under Section 4.4, and Qualified Nonelective
Contributions under Section 4.3 is insufficient to meet the Minimum Benefit
Allocation requirement of Section 4.9.2 or 4.9.3 as applicable, the Company
shall make an additional Profit-Sharing Contribution sufficient to enable the
requirement to be met.

SECTION 4.10 CONDITIONS ON CONTRIBUTIONS.

        Notwithstanding any other provisions of this Article 4, the following
conditions shall apply with respect to Contributions made under the Plan:

        4.10.1 Form of Contributions. Company Contributions may be made in cash
or in kind, or in any combination, provided that contributions in kind may only
be made in property acceptable to the Trustee. The Company shall specify, as to
each Company Contribution payment it makes to the Trust, the Plan Year to which
the payment relates, and what portion of each payment constitutes Participant
Elective Deferral Contributions, Company Matching Contributions, Company
Qualified Nonelective Contributions and/or Company Profit-Sharing Contributions.

        4.10.2 Time for Contributions. Except as provided in Section 4.1.6 with
respect to Participant Elective Deferral Contributions, Company Contributions to
be made for a Plan Year may be paid in installments from time to time during or
after the Plan Year for which they are made, provided that Company Contributions
shall be paid to the Trustee within the time prescribed by law (including
extensions) for filing the Company's federal income tax return for its taxable
year that ends with or within the Plan Year for which such contributions are
made.

        4.10.3 Limitation on Aggregate Contributions.

                (a) The aggregate Contributions for any Plan Year (including
        those distributed as Excess Aggregate ACP Contributions and those
        distributed as Excess Elective Deferrals or Excess ADP Contributions),
        shall not cause the aggregate of all such Contributions to exceed the
        lesser of: (A) the maximum amount deductible under Code section
        404(a)(3) or 404(a)(7), whichever is applicable; or (B) the amount
        which, when allocated according to the provisions of Article 4, would
        result in an Annual Addition (as defined in Section 4.8.4(b)) to a
        Participant's Account equal to the limit specified in Section 4.8.1. If
        the aggregate amount of such Contributions would exceed either of the
        foregoing limits, first Company Profit-Sharing Contributions and then
        Company Qualified Nonelective Contributions shall be reduced (in the
        case of amounts not yet contributed), or, if applicable, returned in
        accordance with Section 4.8.5(b) or adjusted in accordance with Section
        4.8.5(c) (in the case of amounts already contributed).
<PAGE>   34

                (b) No Company Profit-Sharing Contributions, Company Qualified
        Nonelective Contributions or Company Matching Contributions shall be
        made for any Plan Year unless and until any suspense accounts created
        under Sections 4.5.1 and 4.8.5 are exhausted.

        4.10.4 Continuing Plan Qualification. All Contributions made under the
Plan are conditioned upon the continued qualification of the Plan under Code
section 401(a) and the exempt status of the Trust under Code section 501(a).

        4.10.5 Deductibility of Contributions. Any Contributions made under the
Plan are conditioned upon the deductibility of such Contributions under Code
section 404(a).

        4.10.6 Return of Mistaken Contributions. Any Contributions made to the
Plan which are contributed or made by reason of a good faith mistake of fact or
a good faith mistake in determining the deductibility of the Contribution, shall
be returned to the Company as promptly as practicable, but not later than one
year after the mistaken contribution was made or the deduction disallowed. The
amount returned pursuant to the preceding sentence shall be an amount equal to
the excess of the amount actually contributed over the amount that would have
been contributed if the mistake had not been made; provided, however, that gains
attributable to the returnable portion shall be retained in the Trust; and
provided, further, that the returnable portion shall be reduced (A) by any
losses attributable thereto and (B) to avoid a reduction in the balance of any
Participant's Account below the balance that would have resulted if the mistake
had not been made.

        5.2.2 Vesting Upon Death, Disability or Attainment of Normal Retirement
Age. Notwithstanding any other provision of this Article 5, the value of a
Participant's Company Matching Account and Company Profit-Sharing Account shall
be 100% vested and nonforfeitable in the event of (A) such Participant's
separation from Service by reason of his or her death or Disability, or (B) such
Participant's reaching Normal Retirement Age while still an Employee.

        5.2.3 Vesting Upon Termination of the Plan or Complete Discontinuance of
Contributions. Notwithstanding any other provision of this Article 5, in the
event of the termination or partial termination of the Plan or the complete
discontinuance of contributions, the value of the Company Matching Account and
Company Profit-Sharing Account of each Participant who is directly affected by
such termination or discontinuance shall be 100% vested and nonforfeitable as of
the date of such termination or complete discontinuance.

        5.2.4 Vesting Schedule Amendment. In the event of any amendment of the
vesting schedule set forth in this Section 5.2, and notwithstanding any other
provision of this Plan to the contrary, such amendment shall not apply to reduce
the vested and nonforfeitable percentage of any Participant's Company Matching
Account and Company Profit-Sharing Account as of the later of the date such
amendment is adopted or is made effective. For any Participant who has completed
3 Years of Service by the date which is 60 days after the later of the date the
Plan amendment is adopted or the date the Plan amendment becomes effective, the
vested and nonforfeitable percentage of such Participant's Company Matching
Account and Company Profit-Sharing
<PAGE>   36

Account under the Plan as amended shall not, at any time, be less than such
percentage determined without regard to such amendment.

SECTION 5.3 DISREGARDED SERVICE.

        5.3.1 Prior Service of Nonvested Participant After Complete Break in
Service. If no portion of a Participant's Company Matching and Company
Profit-Sharing Account is vested and nonforfeitable at the time such Participant
terminates Service, and if such Participant incurs a Complete Break in Service,
then his or her Service completed prior to the Complete Break in Service shall
be disregarded in determining the vested portion of any amount allocated to his
or her Company Matching Account and Company Profit-Sharing Account after
reemployment.

        5.3.2 Subsequent Service After Five Consecutive One-Year Breaks in
Service. If a Participant incurs 5 consecutive one-year Breaks in Service, his
or her subsequent Service upon reemployment shall be disregarded for purposes of
determining the vested portion of his or her Company Matching Account and
Company Profit-Sharing Account attributable to Company Matching Contributions
and Company Profit-Sharing Contributions credited for periods prior to the 5
consecutive one-year Breaks in Service.

SECTION 5.4 FORFEITURE OF NONVESTED PORTION OF COMPANY MATCHING ACCOUNT AND
COMPANY PROFIT-SHARING ACCOUNT.

        Upon termination of a Participant's Service for any reason at any time,
the nonvested portion of such Participant's Company Matching Account and Company
Profit-Sharing Account shall be forfeited as of the last day of the Plan Year in
which the Participant terminated Service.

SECTION 5.5 RESTORATION OF COMPANY MATCHING ACCOUNT AND COMPANY PROFIT-SHARING
ACCOUNT UPON REEMPLOYMENT.

        5.5.1 No Restoration of Forfeiture Upon Reemployment After Five
Consecutive One-Year Breaks in Service. If a terminated Participant is
reemployed by the Company or an Affiliate after he or she incurs 5 consecutive
one-year Breaks in Service, any amount of his or her Company Matching Account or
Company Profit-Sharing Account forfeited pursuant to Section 5.5 shall not be
restored.

        5.5.2 Restoration Upon Reemployment Before Five Consecutive One-Year
Breaks in Service. If a terminated Participant is reemployed by the Company or
an Affiliate before he or she incurs 5 consecutive one-year Breaks in Service,
the amount of his or her Company Matching Account and Company Profit-Sharing
Account forfeited pursuant to Section 5.4 shall be restored to his or her
Company Matching Account or Company Profit-Sharing Account, as applicable, first
from forfeitures for the Plan Year in which such participant is reemployed, and
then (if necessary) from an additional Company Contribution in accordance with
Section 4.5.2. If the Participant has received a distribution of any or all of
the vested portion of his or her Company Matching Account or Company
Profit-Sharing Account subsequent to his or her termination of Service, the
amount restored shall be made in accordance with the following rules:
<PAGE>   37

                (a) No restoration shall be made unless the Participant repays
        to the Trust Fund the full amount of such distribution.

                (b) Repayment must be made before the earlier of the date the
        Participant incurs 5 consecutive one-year Breaks in Service subsequent
        to the distribution or 5 years after his or her Reemployment Date.

                (c) For purposes of this Section, a Participant whose vested
        Company Matching Account or Company Profit-Sharing Account balance is
        zero shall be deemed to have received a distribution of his or her
        entire vested Company Matching Account or Company Profit-Sharing Account
        balance, as applicable. Upon reemployment before 5 consecutive one-year
        Breaks in Service, such Participant shall be deemed to have repaid the
        full amount of such distribution.

                (d) If the terminated Participant has received a distribution of
        a part but not the entire vested portion of his or her Company Matching
        Account or Company Profit-Sharing Account and does not repay the full
        amount of the distribution in accordance with paragraph (a) of this
        Section 5.5.2, the previously forfeited amount that shall be restored to
        his or her Company Matching Account and Company Profit-Sharing Account
        under this Section shall be the "Restoration Amount" determined by the
        following formula:

                           Restoration Amount = AB x UV
                                                --------
                                                  V

        For purposes of applying this formula, "AB" is the Participant's Company
        Matching Account or Company Profit-Sharing Account balance immediately
        prior to the distribution (as applicable), "UV" is the undistributed
        vested portion of the Participant's Company Matching Account or Company
        Profit-Sharing Account immediately after the distribution (as
        applicable), and "V" is the vested portion of the Company Participant's
        Matching Account or Company Profit-Sharing Account immediately prior to
        the distribution (as applicable).

                                    ARTICLE 6
                 PARTICIPANT ACCOUNTS AND INVESTMENT DIRECTIONS

SECTION 6.1 TRUST FUND ASSETS.

        The Trust Fund shall consist of all Contributions to the Plan, all
investments and reinvestments made therewith, plus all earnings and gains
thereon, less any losses and distributions. The Trustee shall hold and
administer all assets of the Trust Fund.

SECTION 6.2 TYPES OF ACCOUNTS.

        6.2.1 A separate Account shall be established and maintained for each
Participant, in which shall be recorded the amounts allocated thereto and
distributions therefrom and such other information as affects the value of such
Account. As appropriate for each Participant and at the direction of the
Committee, the Participant's Account shall be segregated into the following
subaccounts: a Participant Elective Deferral Account, a Company Matching
Account, a Company Profit-Sharing Account, a Company QNC Account, a Participant
Rollover Account, and a Loan Account.

        6.2.2 If a Participant made any contributions to the Plan in the form of
after-tax Employee voluntary contributions permitted under the Plan during Plan
Years commencing prior to January 1, 1998, until distribution of such voluntary
contributions are made to the Participant in accordance with Section 8, the
Trustee shall maintain a Voluntary Contributions Account subaccount to record
the voluntary contributions so contributed, and the gains and losses
attributable thereto. No further contributions may be made to a Participant's
Voluntary Contributions Account, but in all other respect such Voluntary
Contributions Account shall be maintained in the same manner as the other
subaccounts of Participant's Account and shall be distributable at the times and
in the forms specified in Article 8.

SECTION 6.3 PARTICIPANT INVESTMENT DIRECTIONS.

        6.3.1 Participant Directions for New Contributions. At the time an
Eligible Employee elects to make Participant Elective Deferral Contributions to
the Plan, such Participant shall direct that a percentage (from 10% to 100%, in
multiples of 10%) of all Contributions to be allocated to his or her Account be
invested in one or more of the Investment Funds held by the Trustee for
investment of Participant's Accounts. Such investment direction shall be made on
a form and in such manner as directed by the Committee. Any investment direction
given by a Participant shall continue in effect with respect to all
Contributions allocated to the Participant's Account, and each subaccount
thereof, until changed by the Participant.

        6.3.2 Participant Change in Directions for New Contributions. Once each
calendar quarter, a Participant may change his or her investment directions as
to all Contributions to be allocated to his or her Account. Such change in the
Participant's investment direction shall be made on such form and in such manner
as directed by the Committee, and shall be effective as soon as practicable but
no later than 30 days from the date of its execution and delivery to the
Company.
<PAGE>   39

        6.3.3 Participant Election to Transfer Among Investment Funds. At least
once each calendar quarter, and at such other times as the Committee shall
determine, a Participant may elect to change his or her investment directions
with respect to Contributions previously allocated to his or her Account by
directing that a percentage (from 10% to 100%, in multiples of 10%) of the value
of the Units in any Investment Fund be transferred from such fund to one or more
of the other Investment Funds, subject to such limitations as the Committee
shall determine with respect to transfer among Investment Funds. Such election
to transfer among Investment Funds shall be made on such form and in such manner
as directed by the Committee. Such election to transfer among Investment Funds
shall be effective as soon as practicable but no later than the end of the month
following the month in which such election is delivered to the Company.

SECTION 6.4 INVESTMENT OF FUND EARNINGS.

        Dividends, interest and other distributions received with respect to an
Investment Fund will be invested in that Investment Fund.

SECTION 6.5 INVESTMENT FUND EXPENSES.

        Expenses incurred with respect to an Investment Fund will be charged to
such Investment Fund prior to the determination of the value of a Participant's
interest in such Fund.

SECTION 6.6 VALUATION OF PARTICIPANT ACCOUNTS.

        6.6.1 General Rule. As of each Valuation Date, each Participant's
Account shall be adjusted to reflect the fair market value of the interest held
by such Participant's Account in each Investment Fund in which it is invested,
less a pro-rata share of any expenses (including commissions, sales charges and
soft dollar investment charges) related to the Investment Funds in which such
Participant's Account is invested. The value of a Participant's Account on any
date shall be deemed to be the value of the Account as determined on the
Valuation Date coincident with or next preceding the date of determination, plus
any contributions or other amounts subsequently credited thereto, less any
distributions subsequently made therefrom and less any expenses attributable
thereto.

        6.6.2 Valuation for Distributions. For the purpose of distributing the
amount credited to a Participant's Account, the Trustee shall use a valuation of
the Participant's Account as of the Valuation Date next preceding the date of
distribution, which in no event shall be earlier than the Valuation Date
following the cessation of Participant Elective Deferral Contributions to such
Participant's Account (the "Distribution Valuation Date"). If such valuation is
not available at the time of distribution, the Trustee shall make an initial
valuation and final valuation. The initial valuation shall be the amount
credited to the Participant's Account as of the most recent Valuation Date for
which valuation information is available, reduced by a reasonable amount
necessary to offset any loss that may be allocated to the Participant's Account
as of the Distribution Valuation Date; the final valuation shall be made after
valuation information is available for the Distribution Valuation Date. For
purposes of the valuations provided for herein, the Committee may adopt such
<PAGE>   40

procedures as it considers equitable to establish a proportionate crediting of
Trust income or loss to those portions of Participants' Accounts which have been
paid to Participants in the interim period since the next preceding Valuation
Date.

SECTION 6.7 STATEMENTS OF ACCOUNTS.

        Each Participant shall be furnished with periodic statements of his or
her Account, reflecting the status of his or her interest under the Plan, no
less frequently than annually.
<PAGE>   41

                                    ARTICLE 7

                              LOANS TO PARTICIPANTS

SECTION 7.1 LOAN PROGRAM.

        The Plan shall maintain a loan program administered by the Committee for
the benefit of eligible Participants. Loans shall be made available to all
eligible participants on a reasonable equivalent basis and subject to the
provisions of this Article 7. The Committee shall promulgate such rules and
procedures, not inconsistent with the express provisions of this Article, as it
deems necessary to carry out the purposes of this Article. All such rules and
procedures shall be deemed a part of this Plan for purposes of the Department of
Labor Regulations section 2550.408b-1(d).

SECTION 7.2 PARTICIPANTS ELIGIBLE FOR LOANS.

        The Participants eligible for loans from the Plan shall be (A) all
Participants who are receiving Compensation through the Employer's payroll on a
regular and periodic basis, and (B) all Participants who are former Employees
and are "parties in interest" within the meaning of ERISA section 3(14).
Notwithstanding the preceding sentence, in no event shall a 10% Owner be
eligible for loans from the Plan.

SECTION 7.3 LIMITATIONS ON AMOUNT OF LOAN.

        7.3.1 Maximum Amount of Loan. The amount borrowed by a participant shall
not exceed the value of the aggregate of the Participant's Elective Deferral
Account and Rollover Account and shall not cause the sum of (A) the amount of
the loan, plus (B) the highest aggregate outstanding balance of all of the
Participant's prior loans from this Plan and any other qualified plan maintained
by the Company or an Affiliate during the one-year period ending on the day
before the date the loan is made, to exceed an amount equal to the lesser of:

                (a) $50,000, or

                (b) 50% of the vested and nonforfeitable percentage of the value
        of the Participant's Account (determined as of the Valuation Date
        immediately preceding the date of the loan).

        7.3.2 Minimum Amount of Loan. The minimum amount for any single loan
under the Plan shall be $1,000. A Participant shall not be permitted to borrow
from the Plan unless, upon application of the limitations of Section 7.3.1, he
or she is eligible to borrow at least $1,000 from the Plan.

        7.3.3 Maximum Number of Loans. A participant may have no more than two
loans under the Plan outstanding at any one time.
<PAGE>   42

        7.3.4 Administrative Costs. A Participant shall be required to pay a
reasonable amount for the administrative costs of the loan as determined by the
Committee, which amount shall be included in the loan amount.

SECTION 7.4 SOURCE OF LOAN FUNDS; SEPARATE ACCOUNTING.

        The Participant may designate the investment fund or funds from which
his or her loan is to be made. In the absence of such designation, the loan
shall be made proportionately from all investment funds in which the
Participant's account is invested at the time of the loan. Any loan made to a
Participant shall be treated as a separate investment of the amount credited to
such Participant's Account. In accordance with such treatment, (A) any interest
or principal paid to the Plan on a Participant's loan shall be credited only to
such Participant's Account, and (B) any default on a Participant's loan shall be
charged only against his or her Account. The note evidencing a loan to a
participant under this Article 7 shall be an asset of the Trust which is
allocated to the Account of such participant, and shall for purposes of the Plan
be deemed to have a value at any given time equal to the unpaid principal
balance of the note plus the amount of any accrued but unpaid interest.

SECTION 7.5 NOTE; SECURITY; INTEREST.

        Each loan shall be evidenced by a note signed by the Participant and
shall be secured by 50% of the Participant's vested interest in his or her
Account and, as determined by the Committee, such other collateral of sufficient
value to secure repayment of the loan principal and interest. The loan shall
bear a reasonable rate of interest, as determined by the Committee, commensurate
with the interest rates charged by lending institutions under similar
circumstances. No loan may be made if the Committee determines that such
interest rates exceed the maximum rate permitted by the law of the applicable
State for the specified purpose of the loan.

SECTION 7.6 REPAYMENT.

        A definite repayment schedule shall be established for the loan, which
shall require level and periodic payments of principal and interest not less
frequently than quarterly and over a period not exceeding 5 years (unless the
loan is to be used toward the purchase of a principal residence of the
Participant). Payments on the loan, together with any and all charges imposed by
the Committee or Trustee in connection with the loan, as determined by the
Committee, may be required to be made through payroll deductions, authorized in
writing by the Participant, for such period as the Participant continues to
receive Compensation from the Company. Prepayments shall be permitted in
accordance with procedures established by the Committee.

SECTION 7.7 DEFAULT.

        Section 7.7.1 Determination of Default. If a Participant's loan payment
has not been made within 30 days after it is due, the Committee shall notify the
participant in writing. If the Participant does not make the payment within 30
days of such notice, the loan shall be deemed in default.
<PAGE>   43

        Section 7.7.2 Actions Upon Default. If a Participant loan is determined
by the Committee to be in default, then the Committee shall take, or direct the
Trustee to take, such action as shall be necessary or appropriate in the
circumstances then prevailing. Such action may include, at such time as the
Committee shall determine is prudent, realization upon the security interest of
the Trust Fund in the collateral pledged to secure the loan (including reduction
of the Participant's Account balance by the amount pledged as security for the
loan).

        Section 7.7.3 Default Prior to Distributable Event. If a Participant's
loan is in default prior to such time as a distribution may be made to the
Participant under Article 8, until the first date on which such distribution may
be made, the amount by which the Participant's Account would otherwise be
reduced on account of the default shall be credited to a separate bookkeeping
account and shall be increased annually with the interest rate that applies to
the loan. As of the first date on which a distribution may be made to the
Participant under Article 8, the balance credited to the Participant's Account
shall be reduced by the amount then credited to the defaulted loan bookkeeping
account to the extent the Participant's Account has been pledged as security for
the loan and the amount of such reduction shall be deemed to have been
distributed.

        Section 7.7.4 No Other In-Service Withdrawals While Loan in Default. In
the event of a Participant's default on a loan, such participant shall not be
permitted to make an in-service withdrawal of any portion of his or her Account
under Article 8 until the default is cured.

SECTION 7.8 REPAYMENT UPON DISTRIBUTION.

        If, at the time benefits are to be distributed (or to commence being
distributed) to a Participant with respect to separation from Service, there
remains any unpaid balance of a loan hereunder, such unpaid balance shall, to
the extent consistent with the requirements under ERISA and Code section 401(a),
become immediately due and payable in full. Such unpaid balance, together with
any accrued but unpaid interest on the loan, shall be deducted from the
Participant's Account before any distribution is made. Notwithstanding the
foregoing, if a Participant elects that his or her Account be transferred to a
qualified plan maintained by another employer in a direct rollover pursuant to
Code section 401(a)(31) and in accordance with Section 8.10 of this Plan, and
the eligible retirement plan specified by the Participant permits receipt of the
Participant's loan note as part of an eligible rollover distribution, provided
the loan is not in default at the time of distribution, the unpaid balance of
the loan shall not become payable upon distribution, and the note shall be
transferred in accordance with the Participant's direct rollover election.

                          DISTRIBUTIONS AND WITHDRAWALS

SECTION 8.1 AMOUNT OF BENEFITS.

        All benefits under the Plan shall be distributed solely from the Trust.
The amount of benefits distributable with respect to any Participant shall be
equal to the vested and nonforfeitable portion of the value of his or her
Account (determined as of the Distribution Valuation Date).

SECTION 8.2 DISTRIBUTION EVENTS.

        Distribution of a Participant's benefits shall be made by reason of the
following events:

        8.2.1 Termination of the Participant's Service for any reason, including
retirement, resignation, dismissal, Disability or death, other than termination
of the Participant's Service in connection with the sale of assets or a
subsidiary corporation of the Company;

        8.2.2 The Participant's in-service withdrawal of a portion of his or her
Account in accordance with Section 8.5;

        8.2.3 The Participant's attainment of age 70-1/2 if the Participant is a
5% Owner, and otherwise upon election by such Participant after the
Participant's attainment of age 70-1/2;

        8.2.4 Termination of the Plan in circumstances where the Company does
not establish or maintain a successor defined contribution plan within the
meaning of Treasury Regulation section 1.401(k)(d)(3); or

        8.2.5 Termination of a Participant's Service in connection with the sale
of at least 85% of the assets of the Company or the sale of a subsidiary
corporation of the Company in circumstances where the purchaser does not
maintain the Plan within the meaning of Treasury Regulation section
1.401(k)(d)(4) after such sale of assets or subsidiary. For purposes of this
Section 8.2.5, a Participant shall be considered to have terminated Service if
he or she continues employment with the purchaser of such assets or subsidiary
corporation where such purchaser is not an Affiliate.

SECTION 8.3 TIMES FOR DISTRIBUTION TO PARTICIPANTS.

        8.3.1 Distribution to Participant on Account of Termination of Service
or Termination of the Plan. Distributions permitted under Section 8.2.1 by
reason of the termination of a Participant's Service shall normally be made or
commenced as soon as practicable after the termination of the Participant's
Service, or, if later, as soon as practicable after any consent of the
Participant and Spousal Consent, if applicable, required under this Article 8 is
received by the Committee.

        8.3.2 In-Service Withdrawals. Distributions arising from a Participant's
withdrawal of all or any portion of the vested and nonforfeitable percentage of
his or her Account pursuant to Section 8.5 shall occur as soon as practicable
after the Committee receives the Participant's written
<PAGE>   45

withdrawal request and has determined that the distribution will meet the
requirements of Section 8.5 or, if later, after any Spousal Consent required
under this Article 8 is received by the Committee.

        8.3.3 Consent Required for Early Distribution. If the amount
distributable to a Participant exceeds (or at the time of any prior distribution
exceeded) $5,000, no distribution shall be made or commenced to such Participant
before the Participant attains Normal Retirement Age, unless the Participant has
consented in writing to receive an earlier distribution by making an early
distribution election. Such election shall be in the form and manner determined
by the Committee. A Participant's written request for an in-service withdrawal
pursuant to Section 8.5 shall be deemed to be the consent required under this
Section. A Participant's failure to consent to an early distribution shall be
deemed to be an election to defer distribution to the date the Participant
attains Normal Retirement Age. Notwithstanding the foregoing, upon termination
of the Plan, (A) the Participant's Account may be distributed without the
Participant's consent if the Company does not maintain another defined
contribution plan and (B) the consent of the Participant shall not be required
for a transfer of the Participant's Account balance to any other qualified
defined contribution plan maintained by the Company.

        8.3.4 Required Beginning Date for Distributions After Termination of
Service. All distributions not made or commenced to a Participant sooner
pursuant to the foregoing provisions shall be made or commenced no later than
the 60th day after the latest of the close of the Plan Year in which occurs the
date the Participant terminates Service, or, if later, (A) the date on which the
Participant attains Normal Retirement Age; (B) the 10th anniversary of the date
the Participant first commenced participation in the Plan.

        8.3.5 Distribution Required Upon Attainment of Age 70-1/2. In the case
of a Participant who is a 5% Owner, all distributions not made or commenced
sooner pursuant to one of the foregoing provisions of this Section 7.3 shall be
made or commenced no later than the April 1 that next follows the calendar year
in which such Participant attains age 70-1/2. Any amount allocated to such
Participant's Account after such date shall be distributed as soon as
practicable after such amount is allocated, and in any event no later than the
December 31 following the date as of which such amount is allocated to the
Participant's Account.

        8.3.6 Distribution on Termination of the Plan. Distributions permitted
under Section 8.2.4 upon termination of the Plan shall normally be made or
commenced as soon as practicable after the termination of the Plan; provided,
however, that if the Company makes an application to the Internal Revenue
Service for a determination with respect to the qualified status of the Plan on
termination, distribution shall be made as soon as practicable following the
completion of such determination procedure.

SECTION 8.4 FORM OF DISTRIBUTION.

        8.4.1 Normal Form of Benefit Payment. If the total amount distributable
to a Participant exceeds (or at the time of any prior distribution exceeded)
$5,000, benefits under this Plan shall be payable in one of the following forms:
<PAGE>   46

                (a) a single sum distribution; or

                (b) an installment distribution consisting of approximately
        equal monthly, quarterly, semi-annual or annual installments paid over a
        term certain not extending beyond the Participant's life expectancy (or
        the life expectancy of the Participant and his designated beneficiary).

In the case of an installment distribution, if the Participant's spouse is not
his or her Designated Beneficiary, the method of distribution selected must
assure that at least 50% of the present value of the amount available for
distribution is paid within the life expectancy of the Participant.

        8.4.2 Immediate Single Sum Payment of Small Benefits (Vested Benefit Not
Exceeding $5,000). Notwithstanding any other provision of this Plan with respect
to the time or form of distribution of a Participant's benefits, upon
termination of the Participant's Service for any reason (including death or
Disability), if the vested and nonforfeitable portion of the Participant's
Account balance does not exceed (or at the time of any prior distribution did
not exceed) $5,000, any benefit payable to the Participant of his or her
Beneficiary under this Plan shall be paid in the form of a single sum payment in
cash. Such payment shall be made as soon as practicable after the Participant's
termination of Service. No consent of the Participant or his or her spouse or
Beneficiary shall be required for such distribution.

SECTION 8.5 IN-SERVICE WITHDRAWALS.

        8.5.1 Withdrawals After Attainment of Age 59-1/2. A Participant who has
attained the age of 59-1/2 shall have the right, exercisable in his or her
discretion by written request delivered to the Committee, to withdraw all or any
portion of the balance of his or her Participant Elective Deferral Account
(after reduction for the balance of any outstanding loan), Company QNC Account,
Voluntary Contributions Account (if any) and, if the Participant is 100% vested
therein, his or her Company Matching Account and Company Profit-Sharing Account.
Only one such withdrawal shall be permitted in a Plan Year.

        8.5.2 Hardship Withdrawals. Upon written request by a Participant, the
Committee may authorize a withdrawal by such Participant from his or her
Participant Elective Deferral Account (and Voluntary Contributions Account, if
such subaccount is maintained for the Participant pursuant to Section 6.2.2),
provided that authorization for such withdrawal and the amount thereof shall be
given only on account of hardship incurred by the Participant that imposes
immediate and heavy financial need which may not reasonably be met by the
Participant's other resources. A request for hardship withdrawal shall be made
in such form and manner as the Committee shall direct. Determination of hardship
shall be made by the Committee in a uniform and nondiscriminatory manner and in
accordance with the guidelines established by the Code or regulations
thereunder. A hardship withdrawal shall not exceed the amount required to meet
the immediate financial need created by the hardship and shall not exceed the
aggregate of the Participant Elective Deferral Contributions (and after-tax
voluntary contributions, if a Voluntary
<PAGE>   47

Contributions Account is maintained for the Participant pursuant to Section
6.2.2) made on behalf of the Participant, reduced by any previous hardship
withdrawals made by such Participant.

                (a) For purposes of this Section, "hardship" shall include the
        need to pay the following items, to the extent provided in applicable
        Treasury regulations:

                        (1) nonreimbursable medical expenses of the Participant,
                his or her spouse or dependents;

                        (2) any portion of the purchase price (excluding
                mortgage payments) of a principal residence for the Participant;

                        (3) tuition for the next semester or quarter of
                post-secondary education for the Participant, or for his or her
                spouse or dependents;

                        (4) a payment to prevent eviction of the Participant
                from his or her principal residence or foreclosure on the
                mortgage of the Participant's principal residence;

                (b) A hardship withdrawal shall not be made unless:

                        (1) the Participant represents to the Committee, in the
                form and manner prescribed by the Committee, that the withdrawal
                does not exceed his or her immediate and heavy financial need;
                and

                        (2) the Participant cannot receive any other
                distribution or loan under this Plan or any other plan
                maintained by the Company or an Affiliate.

                (c) If a Participant makes a hardship withdrawal, such
        Participant shall be a "Suspended Participant," and all Participant
        Elective Deferral Contributions that would otherwise be made on his or
        her behalf shall be suspended and reduced as follows: (A) no Participant
        Elective Deferral Contributions may be made to the Plan on his or her
        behalf for the 12 month period beginning on the date of the hardship
        withdrawal, and (B) the amount of Participant Elective Deferral
        Contributions which may be made on his or her behalf for the Plan Year
        immediately following the Plan Year in which the Participant receives
        the hardship distribution shall be reduced by the amount of the hardship
        distribution.

SECTION 8.6 DEATH BENEFITS.

        8.6.1 No Other Death Benefits. Except as provided in this Article 8, no
death or other survivor benefits are provided under the Plan.

        8.6.2 Designated Beneficiary. Subject to the Spousal Consent required in
Section 8.6.5, each Participant may designate one or more individuals to receive
benefits under the Plan on or after the death of the Participant. A Participant
may also designate a trust as one of his or her Beneficiaries, provided the
requirements of proposed Treasury regulation section 1.409(a)(9)-1,
<PAGE>   48

Q&A D-5 are met with respect to such trust. A Participant may change or revoke
his or her designation from time to time. Any designation, change in designation
or revocation of designation shall be made in such form and manner as the
Committee shall direct, and shall become effective only upon its receipt by the
Committee. The last effective designation or revocation received by the
Committee shall supersede all prior designations.

        8.6.3 Failed Beneficiary Designations. If a Participant dies without
having effectively designated a Beneficiary, or if no Beneficiary survives the
Participant, the benefits payable on the Participant's death shall be paid to
the Participant's surviving spouse or, if the Participant is not survived by his
or her spouse, such benefits shall be paid to the following persons (if living)
in the following order of priority: the surviving children (including adopted
children), parents, siblings, nephews and nieces of the Participant, or the
executors and/or administrators of his or her estate. The Committee's
determination as to which persons (if any) qualify within the aforementioned
categories shall be final and conclusive upon all persons.

        8.6.4 Payment of Death Benefits. Upon the death of a Participant, if the
total amount distributable exceeds (or at the time of any prior distribution
exceeded) $5,000, such amount shall be payable as follows:

                (a) Death of Participant After Payment of Benefits. If a
        Participant dies after distribution of his or her benefits has commenced
        in the form of installments, any remaining portion of the Participant's
        benefits not distributed at the time of his or her death shall be
        distributed under the same installment method previously established for
        such Participant, unless the Beneficiary elects a single sum
        distribution or a more rapid form of installment distribution.

                (b) Death of Participant Before Payment of Benefits. If a
        Participant dies before distribution of his or her benefits is made or
        commenced (other than in the form of a withdrawal pursuant to Section
        8.5), the amount distributable with respect to such Participant shall be
        distributed to his or her surviving spouse, or to such other Beneficiary
        as is designated in accordance with this Section 8.6, in the form of a
        single sum payment in cash.

                (c) Remainder of Death Benefits. Any amount distributable with
        respect to a Participant that is not distributed in accordance with
        Sections 8.6.4(a) or (b) above shall be distributed within 5 years after
        the Participant's death.

        8.6.5 Spousal Consent. If a Participant designates any individual other
than his or her spouse (or designates a trust in accordance with Section 8.6.2)
as his or her Beneficiary with respect to benefits otherwise payable to his or
her surviving spouse under Section 8.6.3 of this Plan, the designation shall be
ineffective in the absence of Spousal Consent. Such designation may be revoked
at any time by the Participant, but a new Beneficiary other than the
Participant's spouse may not be substituted in the absence of Spousal Consent to
the new designation unless the previously executed Spousal Consent expressly
permits changes in the Beneficiary designation without any requirement of
further Spousal Consent.
<PAGE>   49

SECTION 8.7 QUALIFIED DOMESTIC RELATIONS ORDER.

        Notwithstanding any other provision of the Article 8, the Trustee may
make distributions pursuant to a qualified domestic relations order (as defined
in Code section 414(p)), provided that the Committee has properly notified the
Participant and any alternate payee of the order and has determined that the
order is a qualified domestic relations order in accordance with the procedures
set forth in Section 10.6.2.

SECTION 8.8 PAYMENTS TO INCOMPETENTS.

        If any individual to whom a benefit is payable under the Plan is a
minor, or if the Committee determines that any individual to whom a benefit is
payable under the Plan is physically or mentally incompetent to receive such
payment or to give a valid release therefor, payment shall be made to the
guardian or other representative of the estate of such individual which has been
duly appointed by a court of competent jurisdiction. If no guardian or other
representative has been appointed, payment may be made to or applied to or for
the benefit of the minor or incompetent, the incompetent's spouse, children or
other dependents, the institution or persons maintaining the minor or
incompetent, or any of them, in such proportions as the Committee from time to
time shall determine. The release of the person or institution receiving the
payment shall be a valid and complete discharge of any liability of the Plan
with respect to any benefit so paid.

SECTION 8.9 UNDISTRIBUTABLE ACCOUNTS.

        8.9.1 General Rule. Each Participant (and in the event of the
Participant's death his or her Beneficiary) shall keep the Committee advised of
his or her current address. If the Committee is unable to locate (A) a
Participant by the close of the fifth Plan Year after the Plan Year in which the
Participant terminated Service or, if earlier, by the 60th day after the close
of the Plan Year during which occurs the Participant's Normal Retirement Date,
or (B) a Beneficiary to whom a Participant's Account is payable under Section
8.6 within 6 months after the death of the Participant (or the death of the
Participant's surviving spouse), the Participant's Account shall be closed. The
balance credited to the Account shall be forfeited and shall be used in
accordance with Section 4.5.1. If a Participant or Beneficiary entitled to a
distribution whose Account was closed under the preceding sentence subsequently
files a claim for distribution of his or her Account, the balance previously
forfeited upon closure of the Account shall be restored to the Account by means
of a special contribution made to the Trust by the Company in accordance with
Section 4.5.2.

        8.9.2 Undistributable Accounts Upon Plan Termination. If any
Participants or Beneficiaries cannot be located within 6 months after
termination of the Plan, the amounts payable to all such Participants or
Beneficiaries shall be deposited in a bank account bearing a reasonable rate of
interest. Each such Participant or Beneficiary shall be credited with an
undivided interest in the account and the earnings thereon and charged with a
pro-rata share of the expenses of such account in proportion to the amount of
such account distributable to him or her upon termination of the Plan. Unless
earlier distributed to a Participant or Beneficiary whom the Committee
determines is entitled to a distribution, any amounts held in such account for
the benefit of a missing
<PAGE>   50

Participant (or his or her Beneficiary) after 5 years from the date of the
termination of the Plan shall be returned to the Company or otherwise disposed
of if so required by applicable law. Such account shall thereupon be closed.

SECTION 8.10 DIRECT ROLLOVERS OF ELIGIBLE DISTRIBUTIONS.

        A Participant who is eligible to receive an "eligible rollover
distribution" within the meaning of Code section 401(c)(4) may elect to have
such distribution paid directly to an "eligible retirement plan" within the
meaning of Code section 401(c)(8)(B) by directing (in such form and at such time
as the Committee may prescribe) that such distribution be made in the form of a
direct trustee-to-trustee transfer to the eligible retirement plan specified by
the Participant (a "direct rollover"). If a Participant elects a direct rollover
of his or her account balance to an eligible retirement plan within the meaning
of Code section 401(c)(8)(B)(iii) maintained by another employer and such plan
accepts rollovers of outstanding loan balances, then such Participant's rollover
shall include any outstanding loan balance under this Plan; provided, however,
that the Participant's loan is not in default at the time of distribution.

        powers.

SECTION 9.2 DELEGATION OF FIDUCIARY DUTIES; EMPLOYMENT OF AGENTS.

persons who are not named fiduciaries with respect to the specific
responsibility or responsibilities so delegated; provided, however, that a named
fiduciary may not delegate its responsibility to manage and control the assets
of the Trust. Any such delegation shall be in writing and shall be made a
permanent part of the records of the named fiduciary. Such delegation shall be

<PAGE>   53

                (b) with the care, skill, prudence and diligence under the

SECTION 10.6 PROCEDURES OF THE COMMITTEE.

        10.6.1 Claims Procedure.

                (a) Claims. A claim is a request for a Plan benefit by a
        Participant or Beneficiary ("Claimant"). Claims, and all requests,
        notices, applications and other communications relating thereto may be
        made directly by a Claimant or indirectly by his or her duly appointed
        representative.

                (b) Claim Filing. A claim is considered to have been filed when
        a written request for benefits from a Claimant is received by the
        Committee or by an officer of the Company.

                (c) Notification of Claims Decision. If a claim is wholly or
        partially denied, the Committee shall provide written notice of the
        decision to the Claimant within 90 days from the date such claim was
        filed. In special circumstances the Committee may take an additional 90
        days to make its determination and in such case shall provide written
        notice of the extension and the reason therefor to the Claimant prior to
        the termination of the initial 90-day period. The notification of claims
        decision shall set forth the following:

                        (1) the specific reason or reasons for the denial;
<PAGE>   57

                        (2) a specific reference to the Plan provision upon
                which the denial is based;

                        (3) a description of any additional material or
                information that the Claimant may use to perfect the claim,
                together with an explanation of why such material or information
                is necessary; and

                        (4) the necessary steps that must be taken if the
                Claimant desires to submit his or her claim for review.

                (d) Review Procedure. Upon written request to the Committee by a
        Claimant the Committee shall review a denied claim. The request shall be
        made within 60 days of the notification of denial and may include issues
        and comments supporting the request for review. The Claimant shall have
        the right to review all pertinent documents as part of the review
        procedure.

                (e) Decision on Review. The Committee shall issue its decision
        on review within 60 days after receipt of the request for review. In
        special circumstances the Committee may take an additional 60 days to
        make its determination and in such case shall provide written notice of
        the extension and the reason therefor to the Claimant prior to the
        termination of the initial 60-day period. The decision on review shall
        be made in writing and shall include specific reasons for the decision
        with references to the pertinent Plan provisions on which the decision
        is based.

10.6.2 Procedure with Respect to Domestic Relations Orders.

                (a) In the case of any domestic relations order received by the
        Plan:

                        (1) the Committee shall promptly notify the Participant
                and any other alternate payee of the receipt of such order and
                the Plan's procedures for determining the qualified status of
                domestic relations orders; and

                        (2) within a reasonable period after receipt of such
                order, the Committee shall determine whether such order is a
                Qualified Domestic Relations Order and notify the Participant
                and each alternate payee of such determination.

                (b) 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 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 such period if the order had been
        determined to be a Qualified Domestic Relations Order.

                (c) If within 18 months the order (or modification thereof) is
        determined to be a Qualified Domestic Relations Order, the Plan shall
        pay the segregated amounts (plus any interest thereon) to the person or
        persons entitled thereto.

<PAGE>   58

                (d) If within 18 months (A) it is determined that the order is
        not a Qualified Domestic Relations Order, or (B) the issue as to whether
        such order is a Qualified Domestic Relations Order is not resolved, then
        the Plan shall pay the segregated amounts (plus any interest thereon) to
        the person or persons who would have been entitled to such amounts if
        there had been no order.

                (e) The term "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 hereunder with respect to such Participant.

                (f) A judgment, decree or order shall not be considered not to
        be a Qualified Domestic Relations order merely because it requires a
        distribution to an alternate payee (or the segregation of accounts
        pending distribution to an alternate payee) before the Participant is
        otherwise entitled to a distribution under the Plan.

                                   THE TRUSTEE

SECTION 11.1 ACCEPTANCE OF TRUST.

        By executing this Agreement, the Trustee hereby accepts the Trust and
agrees to carry out the provisions hereof on its part to be kept and performed.

SECTION 11.2 DUTIES AND POWERS OF TRUSTEE.

        11.2.1 The duties of the Trustee shall be confined to safeguarding and
valuing Trust assets, investing and reinvesting the Trust Fund and carrying out
the directions of the Committee or of the Investment Manager if one has been
appointed. The Trustee shall have the right to act upon said instructions
without notice to any Participant or Beneficiary.

        11.2.2 The Trustee shall not be required to make any investigation to
determine the identity or mailing address of any person entitled to benefits
under this Agreement and shall be entitled to withhold making payments until the
identity and mailing address of any person entitled to benefits are certified by
the Committee. In the event that any dispute shall arise as to the identity or
rights of persons entitled to benefits hereunder, the Trustee may withhold
payment of benefits until such dispute shall have been determined by a court of
competent jurisdiction or shall have been settled by written stipulation of the
parties concerned.

        11.2.3 The Trustee shall not be responsible for any inadequacy of the
Trust Fund to meet and discharge any and all payments under the Plan.

        11.2.4 The Trustee, in addition to and not in limitation of all its
common-law and statutory authority, shall have power with regard to all property
which may at any time, and from time to time, form part of the principal or
income of the Trust Fund:

                (a) to register any securities or other property held hereunder
        in the name of the Trustee, or in the name of a nominee with or without
        the addition of words indicating that such securities or other property
        are held in a fiduciary capacity, and to hold in bearer form any
        securities or other property held hereunder so that title thereto will
        pass by delivery, but the books and records of the Trustee shall show
        that all such investments are part of the Trust Fund;

                (b) with respect to securities held hereunder, to vote, give
        proxies and pay assessments or other charges, to participate in voting
        trusts, pooling agreements, foreclosures, reorganizations,
        consolidations, mergers, and liquidations, and incident thereto to
        deposit securities with and transfer title to any protective or other
        committee upon such terms as it may deem advisable;

                (c) to collect the principal and income of the Trust Fund as the
        same shall become due and payable, and to give binding receipts
        therefor;
<PAGE>   60

                (d) if at any time there shall be a default in the payment of
        such principal or income or any part thereof, to take such action,
        whether by legal proceedings, compromise or otherwise, as it may
        consider advisable;

                (e) to surrender or assign any insurance or annuity contract
        held hereunder as directed in writing by the Committee and as so
        directed to pay the premiums and exercise the rights, privileges,
        options and benefits contained in any such contract;

                (f) to sell for cash or upon terms, convey, exchange, convert,
        and manage the Trust Fund;

                (g) to borrow money, encumber, or hypothecate by mortgage, deed
        of trust, pledge or otherwise, any part of the Trust Fund, to
        compromise, settle or adjust any claim against or in favor of the Trust,
        or sue or defend for or on behalf of the Trust; and to enforce and
        collect all notes, mortgages, bonds, deeds of trust or other choses in
        action at any time constituting a part of the Trust Fund;

                (h) to renew or extend the time of payment of any obligation due
        or becoming due to the Trust Fund, and to foreclose by judicial
        proceedings or otherwise any security belonging to the Trust Fund;

                (i) to participate as a general or limited partner on behalf of
        the Trust Fund in any general or limited partnership; and

                (j) to lease for terms within or beyond the term of this Trust
        and for any purpose, to sell at public or private sale for cash or on
        terms, exchange, partition, grant options, improve, manage, hypothecate
        or otherwise dispose of any real or personal property comprising a part
        of the Trust Fund upon such terms and in such manner as the Trustee in
        its discretion may deem advisable.

SECTION 11.3 INDICIA OF OWNERSHIP OF TRUST ASSETS.

        The Trustee shall not maintain the indicia of ownership of any Trust
assets outside the jurisdiction of the district courts of the United States.

SECTION 11.4 TRUSTEE'S REPORTS.

        11.4.1 Time for Reports; Content. The Trustee shall submit to the
Committee such interim reports or other information as the Committee and the
Trustee shall mutually agree. Within 60 days or within a reasonable period
following (A) each Valuation Date, (B) the effective date of the Trustee's
removal or resignation, or (C) the effective date of the termination of the
Plan, unless a different period is mutually agreed upon, the Trustee shall
submit to the Committee a written report relating to the period following the
period covered by its last report. Such report shall set forth all transactions
relating to the Trust during the applicable period, including (but not limited
to)
<PAGE>   61

investment purchases and sales, receipts, disbursements, additions and
withdrawals, and a listing of the assets of the Trust showing carrying and
market values as of the end of the report period.

        11.4.2 Determinations of Value. The Trustee shall report to the
Committee regarding determinations of the value of the Trust Fund.
Notwithstanding any other provisions of this Agreement, if the Trustee, in
making such determinations, shall determine that the Trust Fund consists, in
whole or in part, of property not traded freely on a recognized market or that
information necessary to ascertain the fair market value thereof is not readily
available to the Trustee, the Trustee shall request the Committee to instruct
the Trustee as to the fair market value of such property for all purposes under
the Plan and Trust Agreement. In such event, the fair market value placed upon
such property by the Committee in its instructions to the Trustee shall be
conclusive and binding. If the Committee shall fail or refuse to instruct the
Trustee as to the fair market value of such property within a reasonable time
after receipt of the Trustee's request to do so, the Trustee shall take such
action as is required to ascertain the fair market value of such property
including the retention of such counsel and independent appraisers as it
considers necessary, and in such event the fair market value so determined shall
be conclusive and binding.

SECTION 11.5 APPROVAL OF TRUSTEE'S ACCOUNTING.

        The written approval of any Trustee accounting by the Company or
Committee shall be final as to all matters and transactions stated or shown
therein and binding upon the Company, Committee, and all persons who then shall
be or thereafter shall become interested in this Trust. Failure of the Company
or Committee to notify the Trustee within 180 days after receipt of any
accounting of its disapproval of such accounting shall be the equivalent of
written approval.

SECTION 11.6 REORGANIZATION OF TRUSTEE.

        Any reorganization or change of entity of the Trustee by means of
merger, consolidation, or otherwise shall cause a succession of trusteeship
hereunder to occur without the execution of any document and without any action
of any kind by any of the parties hereto.

SECTION 11.7 RESIGNATION OR REMOVAL OF TRUSTEE.

        The Trustee may resign at any time upon 60 days' written notice to the
Company, unless a shorter period is acceptable to the Company; provided that
such resignation shall not become effective until appointment and acceptance of
a successor Trustee. The Company may at any time remove the Trustee upon 30
days' written notice to the Trustee, unless a shorter period is acceptable to
the Trustee.

SECTION 11.8 APPOINTMENT OF SUCCESSOR TRUSTEE.

        Resignation or removal of the Trustee shall not terminate the Trust. In
the event of resignation or removal of the Trustee, the Company shall appoint a
successor. The appointment of a successor Trustee may be effected either by
amendment to this Trust Agreement or by resolution of the Board of Directors of
the Company without such amendment, and the agreement of such
<PAGE>   62

successor Trustee to act as such shall be evidenced by its execution of such
amendment or of a certified copy of such resolution. Upon its acceptance in
writing of such appointment delivered to the Company and the former Trustee, the
successor Trustee shall be vested with all the rights, powers and duties of the
Trustee under this Agreement, and the retiring Trustee shall be released and
discharged from all further liability with respect to the future affairs of the
Trust. The title to all Trust property shall automatically vest in a successor
Trustee without the execution or filing of any instrument or the doing of any
act, but the retiring Trustee shall, nevertheless, execute all instruments and
do all acts which would otherwise be necessary to vest such title in any
successor.

SECTION 11.9 EXPENSES, TRUSTEE COMPENSATION AND SETTLEMENT OF ACCOUNTS.

        11.9.1 Compensation and Expenses. The Trustee shall be entitled to
reasonable compensation for its services and shall be reimbursed for all
reasonable expenses incurred by it in performing its duties under this
Agreement. Such compensation shall be set forth in a separate schedule, and such
schedule may be modified from time to time as agreed by the Committee and the
Trustee. Such compensation and expenses shall be paid to the Trustee by the
Company except to the extent that the Committee directs, that any portion of
such compensation and expenses be paid from the Trust Fund, in which case such
amount shall constitute a charge upon the Trust, and may be withdrawn by the
Trustee from the Trust. Notwithstanding the foregoing, no Trustee who is an
Employee shall receive any compensation for his or her services as Trustee from
Trust assets (other than reasonable expenses properly and actually incurred).

        11.9.2 Settlement of Accounts. In case of resignation or removal of the
Trustee, the said Trustee shall have the right of a settlement of accounts,
which may be made at the option of the Trustee, either by judicial settlement in
an action in a court of competent jurisdiction or by agreement of settlement
between the Trustee and the Company. No Employee, Participant, or Beneficiary
shall or may be a party to a settlement of the Trustee's account except in the
event the Trustee elects to join them. However, all Employees, Participants and
Beneficiaries shall in any case be represented in any such settlement by the
Committee.

                        AMENDMENT, TERMINATION OR MERGER

SECTION 12.1 COMPANY'S RIGHT TO AMEND.

        12.1.1 The Company reserves the right to alter or amend this Plan and
Trust Agreement at any time and from time to time by a duly executed written
instrument delivered to the Trustee. The Company, the Trustee, all Participants,
their Beneficiaries and all other persons having any interest hereunder shall be
bound by any such amendment provided, however, that no amendment shall:

                (a) change the duties or liabilities of the Trustee without the
        written consent of the Trustee;

                (b) adversely affect the benefits to which any Participant or
        Beneficiary is entitled hereunder to the extent such benefits are
        attributable to contributions made prior to the date of the amendment;
        or

                (c) provide for the use of funds or assets other than for the
        exclusive benefit of the Participants and their Beneficiaries.

        12.1.2 In the event of any amendment to this Plan which has the effect
of eliminating an optional form of benefit, the benefits derived from the
Participants' Account balances as of the date of the amendment shall not be
affected by such amendment.

SECTION 12.2 COMPANY'S RIGHT TO TERMINATE THE PLAN.

        The Company has established the Plan with the bona fide intention and
expectation that the Plan will continue indefinitely and that it will be able to
make contributions to it indefinitely, but the Company shall be under no
obligation to continue to maintain the Plan for any given length of time and
may, in its sole and absolute discretion, terminate the Plan, or to cause a
partial termination of the Plan, for any reason at any time without any
liability whatsoever.

SECTION 12.3 EFFECT OF TERMINATION OR PARTIAL TERMINATION OF PLAN.

        If the Plan is terminated or partially terminated, or if there is a
complete discontinuance of contributions, then the interests of all Participants
affected by such termination or discontinuance in their Accounts shall become
and remain 100% vested and nonforfeitable. After payment of all expenses of the
Trust, including any compensation then due the Trustee and agents of the
Committee, the Trust assets shall be revalued and the Committee shall cause the
assets of the Plan to be allocated among the Participants' and Beneficiaries'
Accounts in accordance with Article 6. If there are residual assets remaining in
the suspense accounts described in Section 4.5.1 and 4.8.5 upon complete
termination of the Plan, such residual assets shall be returned to the Company.
<PAGE>   64

SECTION 12.4 CONTINUATION OF TRUST AFTER PLAN TERMINATION.

        After the termination of the Plan, the Trust shall continue for the
purpose of preserving the Trust funds and paying out benefits according to its
terms, but subject to the following provisions:

        12.4.1 The members of the Committee last in office prior to the
termination of the Plan shall continue in office until such time as the purposes
of the Trust have been fulfilled and the Trust has been terminated. The
remaining members of the Committee shall have the power to fill such vacancies
as may occur in the Committee from among the Participants in the Plan at the
time of its termination.

        12.4.2 The Trust shall cease and terminate as soon as all of its assets
have been distributed to the Participants or their Beneficiaries, according to
the provisions of Article 7.

SECTION 12.5 MERGER, CONSOLIDATION OR TRANSFER.

        In no event shall this Plan and the Trust be merged or consolidated with
any other plan, nor shall there be any transfer of any assets or liabilities
from this Plan and Trust to any other plan or trust, unless immediately after
such merger, consolidation or transfer, each Participant's accrued benefit, if
such other plan were then to terminate, is at least equal to the accrued benefit
to which the Participant would have been entitled if this Plan had been
terminated immediately before such merger, consolidation or transfer. Any
transfer of a Participant's accrued benefit hereunder shall be conditioned upon
a voluntary fully-informed consent by the Participant to such transfer as
required by Treasury Regulation section 1.411(d)-4.

                               GENERAL PROVISIONS

SECTION 13.1 CONDITION PRECEDENT.

        This Agreement is based upon the condition precedent that the Internal
Revenue Service shall approve and determine that the Plan meets the requirements
of a qualified plan under Code section 401(a) and that the Trust Fund
constitutes an exempt trust under Code section 501(a). If, upon application by
the Company for a favorable determination from the District Director of Internal
Revenue as to the initial qualification of the Plan and the exempt status of the
Trust, a final determination is issued to the effect that the Plan does not
constitute a qualified plan under Code section 401(a) or that the Trust Fund
does not constitute an exempt trust under Code section 501(a), provided such
application was made within the period prescribed under Code section 401(b) for
retroactive plan changes to satisfy Code section 401(a), then, within one year
of such determination, the Trustee shall return the entire Trust Fund (after
adequate provision is made for the Trustee's compensation and reasonable
expenses) to the Company or, to the extent attributable to Rollover
Contributions which have been permitted, to the appropriate Participants, free
and clear of all rights or claims thereto arising under or in connection with
the Plan. The Trust Fund thereupon shall automatically terminate, and the Plan
and the Trust Agreement shall become null and void and have no further effect.

SECTION 13.2 PLAN INFORMATION.

        Each Participant shall be advised of the general provisions of this Plan
and, upon written request addressed to the Committee, shall be furnished with
any information requested, to the extent required by law, regarding his or her
status, rights and privileges under the Plan.

SECTION 13.3 INALIENABILITY.

        Except to the extent otherwise directed by a domestic relations order
which the Committee determines to be a qualified domestic relations order
(within the meaning of Code section 414(p)) or mandated by applicable law, in no
event may either a Participant, a former Participant or his or her spouse,
Beneficiary or estate sell, transfer, anticipate, assign, hypothecate, or
otherwise dispose of any right or interest under the Plan; and such rights and
interests shall not at any time be subject to the claims of creditors nor be
liable to attachment, execution or other legal process.

SECTION 13.4 BENEFITS AND RIGHTS LIMITED BY TERMS OF THIS AGREEMENT.

        The interest of a Participant or Beneficiary under this Plan shall
consist solely of the right of such Participant or Beneficiary to receive such
payments or distributions as shall be directed by the Committee pursuant to the
provisions of this Agreement. No person shall have any rights in or to the Trust
Fund or other assets of the Plan, or under the Plan, except as, and only to the
extent, expressly provided for in this Agreement. The fact that an allocation
shall be or has been made and credited to the Account of a Participant shall not
vest in such Participant or his or her Beneficiary any right, title, or interest
in or to any assets of the Trust except at the time or times and upon the
<PAGE>   66

terms and conditions expressly set forth in this Agreement. Each Employee,
Participant, Beneficiary and other person receiving or entitled to receive
benefits under the Plan shall look solely to the assets of the Trust for
distributions under the Plan, the Company, the Committee and the Trustee shall
have no liability or responsibility therefor. To the maximum extent permissible
under ERISA section 410, neither the Company, the Trustee nor the Committee
shall be subject to any liability or duty under the Plan except as expressly
provided in this Agreement, or for any action taken, omitted or suffered in good
faith.

SECTION 13.5 APPORTIONMENT OF COSTS AND DUTIES.

        All acts required of the Company under this Agreement may be performed
by the Company by itself and for any Affiliate, and the costs of the Plan shall
be equitably apportioned between the Company and any Affiliated Entities.

SECTION 13.6 APPLICABLE LAW.

        The provisions of this Agreement shall be construed, administered and
enforced in accordance with ERISA and, to the extent applicable, the laws of the
State of Washington without application of its conflict of law principles.

SECTION 13.7 SEVERABILITY.

        If any provision of the Plan is held invalid or unenforceable, its
invalidity or unenforceability shall not affect any other provisions of the
Plan, and the Plan shall be construed and enforced as if such provision had not
been included.

SECTION 13.8 ARTICLE AND SECTION HEADINGS AND CAPTIONS.

        The headings of Articles and Sections and captions contained herein and
in the table of contents prefixed to this Agreement are inserted only as a
matter of convenience and for reference and in no way define, limit, enlarge or
describe the scope or intent of this Agreement nor in any way shall affect the
construction of any provision of this Agreement.

SECTION 13.9 AGREEMENT BINDING UPON SUCCESSORS TO PARTIES.

        This Agreement shall be binding upon the heirs, executors,
administrators, successors, and assigns of any and all parties hereto present or
future.

SECTION 13.10 COUNTERPARTS.

        For the convenience of the parties, this Agreement may be executed in
counterparts, each of which is complete in itself and shall be considered to be
the original Agreement. A counterpart of this Agreement shall be delivered to
the Company, the Committee and the Trustee.
