       contributions to the Plan in Sponsor Stock. In the fulfillment of these
       purposes, and subject to the provisions hereinafter set forth, any assets
       of the Trust, up to 100% thereof, may be invested in or used to acquire
       Sponsor Stock in such amount and at such prices as the Sponsor in its

       at the time contributions are to be deposited to a Participant's Separate
       Account, the Participant shall be notified and an investment election
       form shall be provided to him. Until such Participant shall make an

       Participant may elect to receive distribution of the fair market value of
       his Separate Account in the form of Sponsor stock.

       IN WITNESS WHEREOF, the Sponsor has executed this instrument this 25 day

          (3)  any person employed in a "temporary employee" job classification

          (4)  any person performing services for the Employer through an
               employment or leasing agency, including any leased employee
               within the meaning of section 414(n) of the Code, regardless of
               whether such individual is later determined to be an "employee"
               by court of law or regulatory agency;

          (5)  any person performing services as an independent contractor or
               consultant regardless of whether such individual is later
               determined to be an "employee" by court of law or regulatory
               agency; or

          (6)  any employee of a Related Company, except for a Related Company
               which has adopted the Plan.

The Network Associates, Inc. Tax Deferred Savings Plan, originally effective as
of September 15, 1988, is hereby amended and restated in its entirety. The Plan,
as amended and restated hereby, is intended to qualify as a profit-sharing plan
under Section 401(a) of the Code, and includes a cash or deferred arrangement
that is intended to qualify under Section 401(k) of the Code. The Plan is
maintained for the exclusive benefit of eligible employees and their
beneficiaries.

Notwithstanding any other provision of the Plan to the contrary, a Participant's
vested interest in his Separate Account under the Plan on and after the
effective date of this amendment and restatement shall be not less than his
vested interest in his account on the day immediately preceding the effective
date. In addition, notwithstanding any other provision of the Plan to the
contrary, the forms of payment and other Plan provisions that were available
under the Plan immediately prior to the later of the effective date of this
amendment and restatement or the date this amendment and restatement is adopted
and that may not be eliminated under Section 411(d)(6) of the Code shall
continue to be available to Participants who had an account under the Plan on
the day immediately preceding the later of the effective date or the date this
amendment and restatement is adopted.

                                  DEFINITIONS

1.l    Plan Definitions

As used herein, the following words and phrases have the meanings hereafter set
forth, unless a different meaning is plainly required by the context:

The "Administrator" means the Sponsor unless the Sponsor designates another
person or persons to act as such.

An "After-Tax Contribution" means any after-tax employee contribution made by a
Participant as may be permitted under Article V.

The "Beneficiary" of a Participant means the person or persons entitled under
the provisions of the Plan to receive distribution hereunder in the event the
Participant dies before receiving distribution of his entire interest under the
Plan.

The "Code" means the Internal Revenue Code of 1986, as amended from time to
time. Reference to a section of the Code includes such section and any
comparable section or sections of any future legislation that amends,
supplements, or supersedes such section.

The "Compensation" of a Participant for any period means the wages as defined
in Section 3401(a) of the Code, determined without regard to any rules that
limit compensation included in wages based on the nature or location of the
employment or services performed, and all other payments made to him for such
period for services as an Employee for which his Employer is required to furnish
the Participant a written statement under Sections 6041(d) and 6051(a)(3) of the
Code, and excluding reimbursements or other expense allowances, fringe benefits,
moving expenses, deferred compensation, and welfare benefits, but determined
prior to any exclusions for Tax-Deferred Contributions or amounts deferred under
Section 125, 402(e)(3), 402(h), 403(b), or 457(b) of the Code.

Notwithstanding the foregoing, Compensation shall not include the value of any
qualified or non-qualified stock option granted to he Participant by his
Employer to the extent such value is includible in the Participant's taxable
income.

In no event, however, shall the Compensation of a Participant taken into account
under the Plan for any Plan Year exceed (1) $200,000 for Plan Years beginning
prior to January 1, 1994, or (2) $150,000 for Plan Years beginning on or after
January 1, 1994

(subject to adjustment annually as provided in Section 401(a)(17)(B) and
Section 415(d) of the Code; provided, however, that the dollar increase in
effect on January 1 of any calendar year, if any, is effective for Plan Years
beginning in such calendar year). If the Compensation of a Participant is
determined over a period of time that contains fewer than 12 calendar months,
then the annual compensation limitation described above shall be adjusted with
respect to that Participant by multiplying the annual compensation limitation in
effect for the Plan Year by a fraction the numerator of which is the number of
full months in the period and the denominator of which is 12; provided, however,
that no proration is required for a Participant who is covered under the Plan
for less than one full Plan Year if the formula for allocations is based on
Compensation for a period of at least 12 months. In determining the
Compensation, for purposes of applying the annual compensation limitation
described above, of a Participant who is five percent owner or among the ten
Highly Compensated Employees receiving the greatest Compensation for the Plan
Year, the Compensation of the Participant's spouse and of his lineal
descendants who have not attained age 19 as of the close of the Plan Year shall
be included as Compensation of the Participant for the Plan Year. If as a result
of applying the family aggregation rule described in the preceding sentence the
annual compensation limitation would be exceeded, the limitation shall be

Compensation as determined prior to application of the family aggregation rules.

credited to him under the provisions of Article II for purposes of determining
his eligibility to participate in the Plan as may be required under Article III
or Article VI.

contributes to the Plan as may be provided under Article VI or Article XXII.

from time to time. Reference to a section of ERISA includes such section and any
comparable section or sections of any future legislation that amends,
supplements, or supersedes such section.

The "General Fund" means a Trust Fund established by the Trustee as required to
hold and administer any assets of the Trust that are not allocated among any
separate Investment Funds as may be provided in the Plan or the Trust Agreement.
No General Fund shall be established if all assets of the Trust are allocated
among separate Investment Funds.

highly compensated active employee or highly compensated former employee as
defined hereunder.

A "highly compensated active employee" includes any Employee who performs
services for an Employer during the determination year and who (i) was a five

employees for the look back year and received compensation from an Employer
during the look back year in excess of $50,000 (subject to adjustment annually
at the same time and in the same manner as under Section 415(d) of the Code),
(iv) was an officer of an Employer during the look back year and received
compensation during that year in excess of 50 percent of the dollar limitation
in effect for that year under Section 415(b)(1)(A) of the Code or, if no
officer received compensation in excess of that amount for the look back year or
the determination year, received the greatest compensation for the look back
year of any officer, or (v) was one of the 100 employees paid the greatest
compensation by an Employer for the determination year and would be described in
(ii), (iii), or (iv) above if the term "determination year" were substituted for
"look back year".

A "highly compensated former employee" includes any Employee who separated from
service from an Employer and all Related Companies (or is deemed to have
separated from service from an Employer and all Related Companies) prior to the
determination year, performed no services for an Employer during the

       If the lag period is less than 12 months long the dollar amounts
       specified in (ii), (iii), and (iv) above shall be prorated based upon the
       number of months in the lag period.

(b)    The "look back year" means the 12-month period immediately preceding the

       the absence was for one of the purposes enumerated in this paragraph and
       to establish the number of days of absence attributable to such purpose.

       the armed forces of the United States, he shall not incur a severance
       date if he is eligible for reemployment rights under Federal law and he
       returns to work with an Employer or a Related Company within the period
       during which he retains such reemployment rights.

2.2    Crediting of Hours of Service

                                       8

A person shall be credited with continuous service for the aggregate of the
periods of time between his employment commencement date or any reemployment
commencement date and the severance date that next follows such employment
commencement date or reemployment commencement date; provided, however, that an
employee who has a reemployment commencement date within the
12-consecutive-month period following the earlier of the first date of his
absence or his severance date shall be credited with continuous service for the
period between such severance date and reemployment commencement date.

2.4    Eligibility Service

       12-consecutive-month period following the severance date, (2) the
       employee had a nonforfeitable right to any portion of his Separate
       Account, excluding that portion of his Separate Account that is
       attributable to Rollover Contributions, as of the severance date, or (3)
       the period of time between the severance date and his reemployment
       commencement date is less than the greater of five years or his period of
       continuous service determined as of the severance date; and provided,
       however, that solely for purposes of applying this paragraph, if a person
       is on a maternity/paternity absence beyond the first anniversary of the
       first day of such absence, his severance date shall be the second
       anniversary of the first day of such maternity/paternity absence.

3.1     Eligibility

Each Employee who was an Eligible Employee immediately prior to the effective

If a person who terminated employment with an Employer and all Related Companies
is reemployed as an Employee and if he had been an Eligible Employee prior to

employment with an Employer and all Related Companies and who is reemployed by
an Employer or a Related Company to elect to have Tax-Deferred Contributions
made to the Plan on his behalf shall be determined in accordance with Section
3.1 or 3.2.

4.1     Tax-Deferred Contributions

Effective as of the date he becomes an Eligible Employee, or any subsequent
Enrollment Date, each Eligible Employee may elect in writing in accordance with
rules prescribed by the Administrator to have Tax-Deferred Contributions made to
the Plan on his behalf by his Employer as hereinafter provided. An Eligible
Employee's written election shall include his authorization for his Employer to
reduce his Compensation and to make Tax-Deferred Contributions on his behalf and
his election as to the investment of his contributions in accordance with
Article X. Tax-Deferred Contributions on behalf of an Eligible Employee shall
commence with the first payment of Compensation made on or after the date on
which his election is effective.

4.2     Amount of Tax-Deferred Contributions

The amount of Tax-Deferred Contributions to be made to the Plan on behalf of an
Eligible Employee by his Employer shall be an integral percentage of his
Compensation of not less than one percent nor more than 15 percent. In the event
an Eligible Employee elects to have his Employer make Tax-Deferred Contributions
on his behalf, his Compensation shall be reduced for each payroll period by the
percentage he elects to have contributed on his behalf to the Plan in accordance
with the terms of his currently effective reduction authorization.

4.3     Changes in Reduction Authorization

An Eligible Employee may change the percentage of his future Compensation that
his Employer contributes on his behalf as Tax-Deferred Contributions at such
time or times during the Plan Year as the Administrator may prescribe by filing
an amended reduction authorization with his Employer such number of days prior
to the date such change is to become effective as the Administrator shall
prescribe. An Eligible Employee who changes his reduction authorization shall be
limited to selecting a percentage of his Compensation that is otherwise
permitted under Section 4.2. Tax-Deferred Contributions shall be made on behalf
of such Eligible Employee by his Employer pursuant to his amended reduction
authorization filed in accordance with this Section commencing with Compensation
paid to the Eligible Employee on or after the date such filing is effective,
until otherwise altered or terminated in accordance with the Plan.

advance written notice to his Employer as the Administrator shall prescribe. Any
such voluntary suspension shall take effect commencing with Compensation paid to
such Eligible Employee on or after the expiration of the required notice period
and shall remain in effect until Tax-Deferred Contributions are resumed as
hereinafter set forth.

4.5     Resumption of Tax-Deferred Contributions

An Eligible Employee who has voluntarily suspended his Tax-Deferred
Contributions in accordance with Section 4.4 may have such contributions resumed

by filing a new reduction authorization with his Employer such number of days
prior to the date as of which such contributions are to be resumed as the
Administrator shall prescribe.

4.6     Delivery of Tax-Deferred Contributions

As soon after the date an amount would otherwise be paid to an Employee as it
can reasonably be separated from Employer assets, each Employer shall cause to
be delivered to the Trustee in cash all Tax-Deferred Contributions attributable
to such amounts.

A Participant's vested interest in his Tax-Deferred Contributions Sub-Account
shall be at all times 100 percent.

5.1     No After-Tax Contributions

There shall be no After-Tax Contributions made to the Plan.

5.2     Rollover Contributions

An Employee who was a participant in a plan qualified under Section 401 or 403
of the Code and who receives a cash distribution from such plan that he elects
either (i) to roll over immediately to a qualified retirement plan or (ii) to
roll over into a conduit IRA from which he receives a later cash distribution,
may elect to make a Rollover Contribution to the Plan if he is entitled under
Section 402(c)(1), Section 403(a)(4), or Section 408(d)(3)(A) of the Code to
roll over such distribution to another qualified retirement plan. The
Administrator may require an Employee to provide it with such information as it
deems necessary or desirable to show that he is entitled to roll over such
distribution to another qualified retirement plan. An Employee shall make a
Rollover Contribution to the Plan by delivering, or causing to be delivered, to
the Trustee the cash that constitutes the Rollover Contribution amount within 60
days of receipt of the distribution from the plan or from the conduit IRA in the
manner prescribed by the Administrator. If the Employee does not already have
an investment election on file with the Administrator, the Employee shall also
deliver to the Administrator his election as to the investment of his
contributions in accordance with Article X.

the Plan shall be each Plan Year.

6.2     Profit-Sharing Contributions

6.3     Allocation of Profit-Sharing Contributions

Any Profit-Sharing Contribution made by an Employer for a Contribution Period
shall be allocated among its Employees during the Contribution Period who are
eligible to participate in the allocation of Profit-Sharing Contributions for
the Contribution Period, as determined under this Article. The allocable share
of each such Employee shall be in the ratio which his Compensation from the
Employer for the Contribution Period bears to the aggregate of such
Compensation for all such Employees. Notwithstanding any other provision of the
Plan to the contrary, Compensation with respect to any period ending prior to
the date on which an Employee first became eligible to participate in the
allocation of Profit-Sharing Contributions shall be disregarded in determining
the amount of the Employee's allocable share.

6.4     Matching Contributions

Each Employer shall make a Matching Contribution to the Plan for each
Contribution Period in an amount equal to 100 percent of the aggregate
Tax-Deferred Contributions for the Contribution Period made on behalf of its
Employees during the Contribution Period who are eligible to participate in the
allocation of Employer Contributions for the Contribution Period, as determined
under Section 6.8 up to, but not exceeding, the "match level" and 25% of such
aggregate Tax-Deferred Contributions made on behalf of such Employees for the
Contribution Period in excess of the "match level." For purposes of this Section
and Section 6.5, the "match level"

                                       15

Any Matching Contribution made by an Employer for the Contribution Period shall
be allocated among its Employees during the Contribution Period who are eligible
to participate in the allocation of Employer Contributions for the Contribution
Period, as determined under Section 6.8. The allocable share of each such
Employee shall be an amount equal to 100 percent of the Tax-Deferred
Contributions made on his behalf for the Contribution Period up to, but not
exceeding, the "match level" and 25% of such aggregate Tax-Deferred
Contributions made on behalf of such Employees for the Contribution Period in
excess of the "match level."

6.6     Verification of Amount of Employer Contributions by the Sponsor

The Sponsor shall verify the amount of Employer Contributions to be made by each
Employer in accordance with the provisions of the Plan. Notwithstanding any
other provision of the Plan to the contrary, the Sponsor shall determine the
portion of the Employer Contribution to be made by each Employer with respect to
an Employee who transfers from employment with one Employer as an Employee to
employment with another Employer as an Employee.

6.7     Payment of Employer Contributions

Employer Contributions made for a Contribution Period shall be paid in cash to
the Trustee within the period of time required under the Code in order for the
contribution to be deductible by the Employer in determining its Federal income
taxes for the Plan Year.

</TABLE>

Notwithstanding the foregoing, if a Participant is employed by an Employer or a
Related Company on his Normal Retirement Date, the date he becomes physically or
mentally disabled such that he can no longer continue in the service of his
Employer and is eligible to receive a disability benefit under the terms of the
Social Security Act or the date he dies, his vested interest in his Employer
Contributions Sub-Account shall be 100 percent.

6.10    Election of Former Vesting Schedule

If she Sponsor adopts an amendment to the Plan that directly or indirectly
affects the computation of a Participant's vested interest in his Employer
Contributions Sub-Account, any Participant with three or more years of Vesting
Service shall have a right to have his vested interest in his Employer
Contributions Sub-Account continue to be determined under the vesting provisions
in effect prior to the amendment rather than under the new vesting provisions,
unless the vested interest of the Participant in his Employer Contributions
Sub-Account under the Plan as amended is not at any time less than such vested
interest determined without regard to the amendment. A Participant shall
exercise his right under this Section by giving written notice of his exercise
thereof to the Administrator within 60 days after the latest of (i) the date he
receives notice of the amendment from the Administrator, (ii) the effective date
of the amendment, or (iii) the date the amendment is adopted. Notwithstanding
the foregoing, a Participant's vested interest in his Employer Contributions
Sub-Account on the effective date of such an amendment shall not be less than
his vested interest in his Employer Contributions Sub-Account immediately prior
to the effective date of the amendment.

6.11    Forfeitures to Reduce Employer Contributions

Notwithstanding any other provision of the Plan to the contrary, the amount of
the Employer Contribution required under this Article for a Plan Year shall be
reduced by the amount of any forfeitures occurring during the Plan Year that are
not used to pay Plan expenses.

                          LIMITATIONS ON CONTRIBUTIONS

7.1     Definitions

For purposes of this Article, the following terms have the following meanings:

(a)     The "actual deferral percentage" with respect to an Eligible Employee
        for a particular Plan Year means the ratio of the Tax-Deferred
        Contributions made on his behalf for the Plan Year to his test
        compensation for the Plan Year; provided, however, that contributions
        made on a Participant's behalf for a Plan Year shall be included in
        determining his actual deferral percentage for such Plan Year only if
        the contributions are made to the Plan prior to the end of the 12-month
        period immediately following the Plan Year to which the contributions
        relate. The determination and treatment of the actual deferral
        percentage amounts for any Participant shall satisfy such other
        requirements as may be prescribed by the Secretary of the Treasury.

(b)     The "aggregate limit" means the sum of (i) 125 percent of the greater of
        the average contribution percentage for eligible participants other than
        Highly Compensated Employees or the average actual deferral percentage
        for Eligible Employees other than Highly Compensated Employees and (ii)
        the lesser of 200 percent or two plus the lesser of such average
        contribution percentage or average actual deferral percentage, or, if it
        would result in a larger aggregate limit, the sum of (iii) 125 percent
        of the lesser of the average contribution percentage for eligible
        participants other than Highly Compensated Employees or the average
        actual deferral percentage for Eligible Employees other than Highly
        Compensated Employees and (iv) the lesser of 200 percent or two plus the
        greater of such average contribution percentage or average actual
        deferral percentage.

(c)     The "annual addition" with respect to a Participant for a limitation
        year means the sum of the Tax-Deferred Contributions and Employer
        Contributions allocated to his Separate Account for the limitation year
        (including any excess contributions that are distributed pursuant to
        this Article), the employer contributions, employee contributions, and
        forfeitures allocated to his accounts for the

                                       18
<PAGE>   32

        limitation year under any other qualified defined contribution plan
        (whether or not terminated) maintained by an Employer or a Related
        Company concurrently with the Plan, and amounts described in Sections
        415(1)(2) and 419A(d)(2) of the Code allocated to his account for the
        limitation year.

(d)     The "Code Section 402(g) limit" means the dollar limit imposed by
        Section 402(g)(1) of the Code or established by the Secretary of the
        Treasury pursuant to Section 402(g)(5) of the Code in effect on January
        1 of the calendar year in which an Eligible Employee's taxable year
        begins.

(e)     The "contribution percentage" with respect to an eligible participant
        for a particular Plan Year means the ratio of the matching contributions
        made to the Plan on his behalf for the Plan Year to his test
        compensation for such Plan Year, except that, to the extent permitted by
        regulations issued under Section 401(m) of the Code, the Sponsor may
        elect to take into account in computing the numerator of each eligible
        participant's contribution percentage the Tax-Deferred Contributions
        made to the Plan on his behalf for the Plan Year; provided, however,
        that any Tax-Deferred Contributions that were taken into account in
        computing the numerator of an eligible participant's actual deferral.
        percentage may not be taken into account in computing the numerator of
        his contribution percentage; and provided, further, that contributions
        made by or on a Participant's behalf for a Plan Year shall be included
        in determining his contribution percentage for such Plan Year only if
        the contributions are made to the Plan prior to the end of the 12-month
        period immediately following the Plan Year to which the contributions
        relate. The determination and treatment of the contribution percentage
        amounts for any Participant shall satisfy such other requirements as may
        be prescribed by the Secretary of the Treasury.

(f)     An "elective contribution" means any employer contribution made to a
        plan maintained by an Employer or any Related Company on behalf of a
        Participant in lieu of cash compensation pursuant to his written
        election to defer under any qualified CODA as defined in Section 401(k)
        of the Code, any simplified employee pension cash or deferred
        arrangement as described in Section 402(h)(1)(B) of the Code, any
        eligible deferred compensation plan under Section 457 of the Code, or
        any plan as described in Section 501(c)(18) of the Code, and any
        contribution made on

                                       19
<PAGE>   33

        behalf of the Participant by an Employer or a Related Company for the
        purchase of an annuity contract under Section 403(b) of the Code
        pursuant to a salary reduction agreement.

(g)     An "eligible participant" means any Employee who is eligible to have
        Tax-Deferred Contributions made on his behalf (if Tax-Deferred
        Contributions are taken into account in computing contribution
        percentages) or to participate in the allocation of matching
        contributions.

(h)     A "family member" of an Employee means the Employee's spouse, his lineal
        ascendants, his lineal descendants, and the spouses of such lineal
        ascendants and descendants.

(i)     A "limitation year" means the Plan Year.

(j)     A "matching contribution" means any employer contribution allocated to
        an Eligible employee's account under the plan or any other plan of an
        Employer or a Related Company solely on account of elective
        contributions made on his behalf or employee contributions made by him.

(k)     The "test compensation" of an Eligible Employee for a Plan Year means
        compensation as defined in Section 414(s) of the Code and regulations
        issued thereunder, limited, however, to (1) $200,000 for Plan Years
        beginning prior to January 1, 1994, or (2) $150,000 for Plan Years
        beginning on or after January 1, 1994 (subject to adjustment annually as
        provided in Section 401(a)(17)(B) and Section 415(d) of the Code;
        provided, however, that the dollar increase in effect on January 1 of
        any calendar year, if any, is effective for Plan Years beginning in such
        calendar year) and further limited solely to test compensation of an
        Employee attributable to periods of time when he is an Eligible
        Employee. If the test compensation of a Participant is determined over a
        period of time that contains fewer than 12 calendar months, then the
        annual compensation limitation described above shall be adjusted with
        respect to that Participant by multiplying the annual compensation
        limitation in effect for the Plan Year by a fraction the numerator of
        which is the number of full months in the period and the denominator of
        which is 12; provided, however, that no proration is required for a
        Participant who is covered under the Plan for less than one full Plan
        Year if the formula for allocations is based on Compensation for a
        period of at least 12 months. In determining the test

                                       20
<PAGE>   34

        compensation for purposes of applying the annual compensation
        limitation described above, of a Participant who is a five-percent owner
        or among the ten Highly Compensated Employees receiving the greatest
        test compensation for the limitation year the test compensation of the
        Participant's spouse and of his lineal descendants who have not attained
        age 19 as of the close of the limitation year shall be included as test
        compensation of the Participant for the limitation year. If as a result
        of applying the family aggregation rule described in the preceding
        sentence the annual compensation limitation would be exceeded, the
        limitation shall be prorated among the affected family members in
        proportion to each member's test compensation as determined prior to
        application of the family aggregation rules.

7.2     COde Section 402(g) Limit

In no event shall the amount of the Tax-Deferred Contributions made on behalf of
an Eligible Employee for his taxable year, when aggregated with any elective
contributions made on behalf of the Eligible Employee under any other plan of an
Employer or a Related Company for his taxable year, exceed the Code Section
402(g) limit. In the event that the Administrator determines that the reduction
percentage elected by an Eligible Employee will result in his exceeding the Code
Section 402(g) limit, the Administrator may adjust the reduction authorization
of such Eligible Employee by reducing the percentage of his Tax-Deferred
Contributions to such smaller percentage that will result in the Code Section
402(g) limit not being exceeded. If the Administrator determines that the
Tax-Deferred Contributions made on behalf of an Eligible Employee would exceed
the Code Section 402(g) limit for his taxable year, the Tax-Deferred
Contributions for such Participant shall be automatically suspended for the
remainder, if any, of such taxable year.

If an Employer notifies the Administrator that the Code Section 402(g) limit has
nevertheless been exceeded by an Eligible Employee for his taxable year, the
Tax-Deferred Contributions that, when aggregated with elective contributions
made on behalf of the Eligible Employee under any other plan of an Employer or a
Related Company, would exceed the Code Section 402(g) limit, plus any income and
minus any losses attributable thereto, shall be distributed to the Eligible
Employee no later than the April 15 immediately following such taxable year. Any
Tax-Deferred Contributions that are distributed to an Eligible Employee in
accordance with this Section shall not be taken into

                                       21
<PAGE>   35
account in computing the Eligible Employee's actual deferral percentage for the
Plan Year in which the Tax-Deferred Contributions were made, unless the Eligible
Employee is a Highly Compensated Employee. If an amount of Tax-Deferred
Contributions is distributed to a Participant in accordance with this Section,
matching contributions that are attributable solely to the distributed
Tax-Deferred Contributions, plus any income and minus any losses attributable
thereto, shall be forfeited by the Participant. Any such forfeited amounts shall
be treated as a forfeiture under the Plan in accordance with the provisions of
Article XIV as of the last day of the month in which the distribution of
Tax-Deferred Contributions pursuant to this Section occurs.

7.3     Limitation on Tax-Deferred Contributions of Highly Compensated
        Employees

Notwithstanding any other provision of the plan to the contrary, the
Tax-Deferred Contributions made with respect to a Plan Year on behalf of
Eligible Employees who are Highly Compensated Employees may not result in an
average actual deferral percentage for such Eligible Employees that exceeds the
greater of:

(a)     a percentage that is equal to 125 percent of the average
        actual deferral percentage for all other Eligible Employees; or

(b)     a percentage that is not more than 200 percent of the average actual
        deferral percentage for all other Eligible Employees and that is not
        more than two percentage points higher than the average actual deferral
        percentage for all other Eligible Employees.

In order to assure that the limitation contained herein is not exceeded with
respect to a Plan Year, the Administrator is authorized to suspend completely
further Tax-Deferred Contributions on behalf of Highly Compensated Employees for
any remaining portion of a Plan Year or to adjust the projected actual deferral
percentages of Highly Compensated Employees by reducing their percentage
elections with respect to Tax-Deferred Contributions for any remaining portion
of a Plan Year to such smaller percentages that will result in the limitation
set forth above not being exceeded. In the event of any such suspension or
reduction, Highly Compensated Employees affected thereby shall be notified of
the reduction or suspension as soon as possible and shall be given an
opportunity to make a new Tax-Deferred Contribution election to be effective the
first day of the next following Plan Year. In the absence of such an election,
the election

                                       22
<PAGE>   36

in effect immediately prior to the suspension or adjustment described
above shall be reinstated as of the first day of the next following Plan Year.

For purposes of applying the limitation contained in this Section, the
Tax-Deferred Contributions and test compensation of any Eligible Employee who is
a family member of another Eligible Employee who is a five percent owner or
among the ten Highly Compensated Employees receiving the greatest test
compensation for the Plan Year shall be aggregated with the Tax-Deferred
Contributions and test compensation of such other Eligible Employee, and such
family member shall not be considered an Eligible Employee for purposes of
determining the average actual deferral percentage for all other Eligible
Employees.

In determining the actual deferral percentage for any Eligible Employee who is a
Highly Compensated Employee for the Plan Year, elective contributions made to
his accounts under any other plan of an Employer or a Related Company shall be
treated as if all such contributions were made to the Plan; provided, however,
that if such a plan has a plan year different from the Plan Year, any such
contributions made to the Highly Compensated Employee's accounts under the plan
for the plan year ending with or within the same calendar year as the Plan Year
shall be treated as if such contributions were made to the Plan. Notwithstanding
the foregoing, such contributions shall not be treated as if they were made to
the Plan if regulations issued under Section 401(k) of the Code do not permit
such plan to be aggregated with the Plan.

If one or more plans of an Employer or Related Company are aggregated with the
Plan for purposes of satisfying the requirements of Section 401(a)(4) or
410(b) of the Code, then actual deferral percentages under the Plan shall be
calculated as if the Plan and such one or more other plans were a single plan.
For Plan Years beginning after December 31, 1991, plans may be aggregated to
satisfy Section 401(k) of the Code only if they have the same plan year.

The Administrator shall maintain records sufficient to show that the limitation
contained in this Section was not exceeded with respect to any Plan Year.

7.4     Distribution of Excess Tax-Deferred Contributions

Notwithstanding any other provision of the Plan to the contrary, in the event
that the limitation contained in Section 7.3 is exceeded in any Plan Year, the
Tax-Deferred Contributions made with respect to a Highly Compensated

                                       23
<PAGE>   37

Employee that exceed the maximum amount permitted to be contributed to the Plan
on his behalf under Section 7.3, plus any income and minus any losses
attributable thereto, shall be distributed to the Highly Compensated Employee
prior to the end of the next succeeding Plan Year. If excess amounts are
attributable to Participants aggregated under the family aggregation rules
described in Section 7.3, the excess shall be allocated among family members in
proportion to the Tax-Deferred Contributions made with respect to each family
member. If such excess amounts are distributed more than 2 1/2 months after the
last day of the Plan Year for which the excess occurred, an excise tax may be
imposed under Section 4979 of the Code on the Employer maintaining the Plan with
respect to such amounts.

The maximum amount permitted to be contributed to the Plan on a Highly
Compensated Employee's behalf under Section 7.3 shall be determined by reducing
Tax-Deferred contributions made on behalf of Highly Compensated Employees in
order of their actual deferral percentages beginning with the highest of such
percentages.

If an amount of Tax-Deferred Contributions is distributed to a Participant in
accordance with this Section, matching contributions that are attributable
solely to the distributed Tax-Deferred Contributions, plus any income and minus
any losses attributable thereto, shall be forfeited by the Participant. Any such
forfeited amounts shall be treated as a forfeiture under the Plan in accordance
with the provisions of Article XIV as of the last day of the month in which the
distribution of Tax-Deferred Contributions pursuant to this Section occurs.

7.5     Limitation on Matching Contributions of Highly Compensated Employees

Notwithstanding any other provision of the Plan to the contrary, the matching
contributions made with respect to a Plan Year on behalf of eligible
participants who are Highly Compensated Employees may not result in an average
contribution percentage for such eligible participants that exceeds the greater
of:

(a)     a percentage that is equal to 125 percent of the average contribution
        percentage for all other eligible participants; or

(b)     a percentage that is not more than 200 percent of the average
        contribution percentage for all other eligible participants and that is
        not more than two percentage points higher than the average

                                       24
<PAGE>   38

        contribution percentage for all other eligible participants.

For purposes of applying the limitation contained in this Section, the matching
contributions, Tax-Deferred Contributions to the extent that such Tax-Deferred
Contributions are taken into account in computing contribution percentages and
test compensation of any eligible participant who is a family member of another
eligible participant who is a five percent owner or among the ten Highly
Compensated Employees receiving the greatest test compensation for the Plan
Year shall be aggregated with the matching contributions, Tax-Deferred
Contributions, and test compensation of such other eligible participant, and
such family member shall not be considered an eligible participant for purposes
of determining the average contribution percentage for all other eligible
participants.

In determining the contribution percentage for any eligible participant who is a
Highly Compensated Employee for the Plan Year; matching contributions, employee
contributions, and elective contributions (to the extent that elective
contributions are taken into account in computing contribution percentages) made
to his accounts under any other plan of an Employer or a Related Company shall
be treated as if all such contributions were made to the Plan; provided, however
that if such a plan has a plan year different from the Plan Year, any such
contributions made to the Highly Compensated Employee's accounts under the plan
for the plan year ending with or within the same calendar year as the Plan Year
shall be treated as if such contributions were made to the Plan. Notwithstanding
the foregoing, such contributions shall not be treated as if they were made to
the Plan if regulations issued under Section 401(m) of the Code do not permit
such plan to be aggregated with the Plan.

If one or more plans of an Employer or a Related Company are aggregated with the
Plan for purposes of satisfying the requirements of Section 401(a)(4) or 410(b)
of the Code, the contribution percentages under the Plan shall be calculated as
if the Plan and such one or more other plans were a single plan. For Plan Years
beginning after December 31, 1989, plans may be aggregated to satisfy Section
401(m) of the Code only if they have the same plan year.

The Administrator shall maintain records sufficient to show that the limitation
contained in this Section was not exceeded with respect to any Plan Year and the
amount of the elective contributions taken into account in computing
contribution percentages for any Plan Year.

7.6     Forfeiture or Distribution of Excess Contributions

Notwithstanding any other provision of the Plan to the contrary, in the event
that the limitation contained in Section 7.5 is exceeded in any Plan Year, the
matching contributions made on behalf of a Highly Compensated Employee that
exceed the maximum amount permitted to be contributed to the Plan on behalf of
such Highly Compensated Employee under Section 7.5, plus any income and minus
any losses attributable thereto, shall be forfeited, to the extent forfeitable,
or distributed to the Participant prior to the end of the next succeeding Plan
Year as hereinafter provided. If excess amounts are attributable to participants
aggregated under the family aggregation rules described in Section 7.5, the
excess shall be allocated among family members in proportion to the matching
contributions made with respect to each family member. If such excess amounts
are distributed more than 2 1/2 months after the last day of the Plan Year for
which the excess occurred, an excise tax may be imposed under Section 4979 of
the Code on the Employer maintaining the Plan with respect to such amounts.

The maximum amount permitted to be contributed to the Plan on behalf of a Highly
Compensated Employee under Section 7.5 shall be determined by reducing matching
contributions made on behalf of Highly Compensated Employees in order of their
contribution percentages beginning with the highest of such percentages.

Any amounts forfeited with respect to a Participant pursuant to this Section
shall be treated as a forfeiture under the Plan in accordance with the
provisions of Article XIV as of the last day of the month in which the
distribution of contributions pursuant to this Section occurs. Excess matching
contributions shall be distributable to the extent the Participant has a vested
interest in his Employer Contributions Sub-Account that is attributable to
matching contributions. The determination of the amount of excess matching
contributions shall be made after application of Section 7.4, if applicable.

7.7     Multiple Use Limitation

Notwithstanding any other provision of the Plan to the contrary, the following
multiple use limitation as required under Section 401(m) of the Code shall
apply the sum of the average actual deferral percentage for Eligible Employees
who are Highly Compensated Employees and the average contribution percentage for
eligible participants who are Highly Compensated Employees may not exceed the

                                       26
<PAGE>   40

aggregate limit. In the event that, after satisfaction of Section 7.4 and
Section 7.6, it is determined contributions under the Plan fail to satisfy the
multiple use limitation contained herein, the multiple use limitation shall be
satisfied by further reducing the actual deferral percentages of Eligible
Employees who are Highly Compensated Employees (beginning with the highest such
percentage) to the extent necessary to eliminate the excess, with such further
reductions to be treated as excess Tax-Deferred Contributions and disposed of as
provided in Section 7.4, or in an alternative manner, consistently applied, that
may be permitted by regulations issued under Section 401(m) of the Code.

7.8     Determination of Income or Loss

The income or loss attributable to excess contributions that are distributed
pursuant to this Article shall be determined for the preceding Plan Year under
the method otherwise used for allocating income or loss to Participant's
Separate Accounts.

7.9     Code Section 415 Limitations on Crediting of Contributions and
        Forfeitures

Notwithstanding any other provision of the Plan to the contrary, the
annual addition with respect to a Participant for a limitation year shall in no
event exceed the lesser of (i) the greater of $30,000 or 25 percent of the
defined benefit dollar limitation set forth in Section 415(b)(1) of the Code
in effect for the limitation year or (ii) 25 percent of the Participant's
compensation, as defined in Section 415(c)(3) of the Code and regulations issued
thereunder, for the limitation year. If the annual addition to the Separate
Account of a Participant in any limitation year would otherwise exceed the
amount that may be applied for his benefit under the limitation contained in
this Section, the limitation shall be satisfied by reducing contributions made
on behalf of the Participant to the extent necessary in the following order:

        Tax-Deferred Contributions made on the Participant's behalf for the
        limitation year that have not been matched, if any, shall be reduced.

        Tax-Deferred Contributions made on the Participant's behalf for the
        limitation year that have been matched and the matching contributions
        attributable thereto, if any, shall be reduced pro rata.

The amount of any reduction of Tax-Deferred Contributions

                                       27
<PAGE>   41

(plus any income attributable thereto) shall be returned to the Participant. For
purposes of this Article, excesses shall result only from the allocation of
forfeitures, a reasonable error in estimating a Participant's annual
compensation (as defined in Section 415(c)(3) of the Code and regulations
issued thereunder), a reasonable error in determining the amount of Tax-Deferred
Contributions that may be made with respect to any Participant under the limits
of Section 415 of the Code, or other limited facts and circumstances that
justify the availability of the provisions set forth above.

7.10    Coverage Under Other Qualified Defined Contribution Plan

If a Participant is covered by any other qualified defined contribution plan
(whether or not terminated) maintained by an Employer or a Related Company
concurrently with the Plan, and if the annual addition for the limitation year
would otherwise exceed the amount that may be applied for the Participant's
benefit under the limitation contained in Section 7.9, such excess shall be
reduced first by returning the employee contributions made by the Participant
for the limitation year under all of the defined contribution plans other than
the Plan and the income attributable thereto to the extent necessary. If the
limitation contained in Section 7.9 is still not satisfied after returning all
of the employee contributions made by the Participant under all such other
plans, the procedure set forth in Section 7.9 shall be invoked to eliminate any
such excess. If the limitation contained in Section 7.9 is still not satisfied
after invocation of the procedure set forth in Section 7.9, the portion of the
employer contributions and of forfeitures for the limitation year under all such
other plans that has been allocated to the Participant thereunder, but which
exceeds the limitation set forth in Section 7.9, shall be deemed a forfeiture
for the limitation year and shall be disposed of as provided in such other
plans; provided, however, that if the Participant is covered by a money purchase
pension plan, the forfeiture shall be effected first under any other defined
contribution plan that is not a money purchase pension plan and, if the
limitation is still not satisfied, then under such money purchase pension plan.

7.11    Coverage Under Qualified Defined Benefit Plan

If a Participant in the Plan is also covered by a qualified defined benefit plan
(whether or not terminated) maintained by an Employer or a Related Company, in
no event shall the sum of the defined benefit plan fraction (as defined in

                                       28
<PAGE>   42

Section 415(e)(2) of the Code) and the defined contribution plan fraction (as
defined in Section 415(e)(3) of the Code) exceed 1.0 in any limitation year.
If, before October 3, 1973, the Participant was an active participant in a
qualified defined benefit plan maintained by an Employer or a Related Company
and otherwise satisfies the requirements of Section 2004(d)(2) of ERISA, then
for purposes of applying this Section, the defined benefit plan fraction shall
not exceed 1.0. In the event the special limitation contained in this Section is
exceeded, the benefits otherwise payable to the Participant under any such
qualified defined benefit plan shall be reduced to the extent necessary to meet
such limitation.

7.12    Scope of Limitations

The limitations contained in Sections 7.9, 7.10, and 7.11 shall be applicable
only with respect to benefits provided pursuant to defined contribution plans
and defined benefit plans described in Section 415(k) of the Code.

A Participant's Separate Account shall be divided into individual Sub-Accounts
reflecting the portion of the Participant's Separate Account that is derived
from Tax-Deferred Contributions, Rollover Contributions, or Employer

to each Trust Fund established hereunder and the earnings and losses
attributable thereto. Such other Sub-Accounts may be established as are
necessary or appropriate to reflect a Participant's interest in the Trust.

10.1 Future Contribution Investment Elections

Each Eligible Employee shall make an investment election in the manner and form
prescribed by the Administrator directing the manner in which his Tax-Deferred
Contributions, Rollover Contributions, and Employer Contributions shall be
invested. An Eligible Employee's investment election shall specify the
percentage, in the percentage increments prescribed by the Administrator, of
such contributions that shall be allocated to one or more of the Investment
Funds with the sum of such percentages equaling 100 percent. The investment
election by a Participant shall remain in effect until his entire interest under
the Plan is distributed or forfeited in accordance with the provisions of the
Plan or until he files a change of investment election with the Administrator,
in such form as the Administrator shall prescribe. A Participant's change of
investment election may be made effective as of the date or dates designated by
the Administrator.

10.2 Deposit of Contributions

All Tax-Deferred Contributions, Rollover Contributions, and Employer
Contributions shall be deposited in the Trust and allocated among the Investment
Funds in accordance with the Participant's currently effective investment
election. If no investment election is on file with the Administrator at the
time contributions are to be deposited to a Participant's Separate Account, the
Participant shall be notified and an investment election form shall be provided
to him. Until such Participant shall make an effective election under this
Section, his contributions shall be allocated among the Investment Funds as
directed by the Administrator.

10.3 Election to Transfer Between Funds

A Participant may elect to transfer investments from any Investment Fund to any
other Investment Fund. The Participant's transfer election shall specify either

restrictions pertaining to a particular Investment Fund, a Participant's
transfer election may be made effective as of the date or dates designated by

                     CREDITING AND VALUING SEPARATE ACCOUNTS

11.1 Crediting Separate Accounts

All contributions made under the provisions of the Plan shall be credited to
Separate Accounts in the Trust Funds by the Trustee, in accordance with
procedures established in writing by the Administrator, either when received or
on the succeeding Valuation Date after valuation of the Trust Fund has been
completed for such Valuation Date as provided in Section 11.2, as shall be
determined by the Administrator.

11.2 Valuing Separate Accounts

Separate Accounts in the Trust Funds shall be valued by the Trustee on the
Valuation Date, in accordance with procedures established in writing by the
Administrator, either in the manner adopted by the Trustee and approved by the
Administrator or in the manner set forth in Section 11.3 as Plan valuation
procedures, as determined by o the Administrator.

11.3 Plan Valuation Procedures

With respect to the Trust Funds, the Administrator may determine that the
following valuation procedures shall be applied. As of each Valuation Date
hereunder, the portion of any Separate Accounts in a Trust Fund shall be
adjusted to reflect any increase or decrease in the value of the Trust Fund for
the period of time occurring since the immediately preceding Valuation Date for
the Trust Fund (the "valuation period") in the following manner:

(a)     First, the value of the Trust Fund shall be, determined by valuing all
        of the assets of the Trust Fund at fair market value.

(b)     Next, the net increase or decrease in the value of the Trust Fund
        attributable to net income and all profits and losses, realized and
        unrealized, during the valuation period shall be determined on the basis
        of the valuation under paragraph (a) taking into account appropriate
        adjustments for contributions, loan payments, and transfers to and
        distributions, withdrawals, loans, and transfers from such Trust Fund
        during the valuation period.

(c)     Finally, the net increase or decrease in the value of the Trust Fund
        shall be allocated among Separate

                                       35
<PAGE>   49

        Accounts in the Trust Fund in the ratio of the balance of the portion of
        such Separate Account in the Trust Fund as of the preceding Valuation
        Date less any distributions, withdrawals, loans, and transfers from such
        Separate Account balance in the Trust Fund since the Valuation Date to
        the aggregate balances of the portions of all Separate Accounts in the
        Trust Fund similarly adjusted, and each Separate Account in the Trust
        Fund shall be credited or charged with the amount of its allocated
        share. Notwithstanding the foregoing, the Administrator may adopt such
        accounting procedures as it considers appropriate and equitable to
        establish a proportionate crediting of net increase or decrease in the
        value of the Trust Fund for contributions, loan payments, and transfers
        to and distributions, withdrawals, loans, and transfers from such Trust
        Fund made by or on behalf of a Participant during the valuation period.

11.4 Finality of Determinations

The Trustee shall have exclusive responsibility for determining the balance of
each Separate Account maintained hereunder. The Trustee's determinations thereof
shall be conclusive upon all interested parties.

11.5 Notification

Within a reasonable period of time after the end of each Plan Year, the
Administrator shall notify each Participant and Beneficiary of the balances of
his Separate Account and Sub-Accounts as of the last day of such Plan Year.

                                      LOANS

12.1 Application for Loan

A Participant who is a party in interest may make written application to the
Administrator for a loan from Separate Account. Loans shall be made to
Participants in accordance with written rules prescribed by the Administrator
which are set forth in an Addendum to the Plan.

As collateral for any loan granted hereunder, the Participant shall grant to the
Plan a security interest in his vested interest under the Plan equal to the
amount of the loans; provided, however, that in no event may the security
interest exceed 50 percent of the Participant's vested interest under the Plan
determined as of the date as of which the loan is originated in accordance
with Plan provisions. In the case of a Participant who is an active employee,
the Participant also shall enter into an agreement to repay the loan by payroll
withholding. No loan in excess of 50 percent of the Participant's vested
interest under the Plan shall be made from the Plan. Loans shall not be made
available to Highly Compensated. Employees in an amount greater than the amount
made available to other employees.

A loan shall not be granted unless the Participant consents in writing to the
charging of his Separate Account in accordance with the provisions of Section
12.4 for unpaid principal and interest amounts in the event the loan is declared
to be in default.

12.2 Reduction of Account Upon Distribution

Notwithstanding any other provision of the Plan, the amount of a Participant's
Separate Account that is distributable to the Participant or his Beneficiary
under Article XIII or XV shall be reduced by the portion of his vested interest
that is held by the Plan as security for any loan outstanding to the
Participant, provided that the reduction is used to repay the loan. If
distribution is made because of the Participant's death prior to the
commencement of distribution of his Separate Account and less than 100 percent
of the Participant's vested interest in his Separate Account (determined
without regard to the preceding sentence) is payable to his surviving spouse,
then the balance of the Participant's vested interest in his Separate Account
shall be adjusted by reducing the vested account balance by the amount of the
security used to repay the

                                       37
<PAGE>   51

loan, as provided in the preceding sentence, prior to determining the amount of
the benefit payable to their surviving spouse.

12.3 Requirements to Prevent a Taxable Distribution

Notwithstanding any other provision of the Plan to the contrary, the following
terms and conditions shall apply to any loan made to a Participant under this
Article:

(a)     The interest rate on any loan to a Participant shall be a reasonable
        interest rate commensurate with current interest rates charged for
        loans made under similar circumstances by persons in the business of
        lending money.

(b)     The amount of any loan to a Participant (when added to the outstanding
        balance of all other loans to the Participant from the Plan or any other
        plan maintained by an Employer or a Related Company) shall not exceed
        the lesser of:

        (i)     $50,000, reduced by the excess, if any, of the highest
                outstanding balance of any other loan to the Participant from
                the Plan or any other plan maintained by an Employer or a
                Related Company during the preceding 12-month period over the
                outstanding balance of such loans on the date a loan is made
                hereunder; or

        (ii)    50 percent of the vested portions of the Participant's Separate
                Account and his vested interest under all other plans maintained
                by an Employer or a Related Company.

(c)     The term of any loan to a Participant shall be no greater than five
        years, except in the case of a loan used to acquire any dwelling unit
        which within a reasonable period of time is to be used (determined at
        the time the loan is made) as a principal residence of the Participant.

(d)     Except as otherwise permitted under Treasury regulations, substantially
        level amortization shall be required over the term of the loan with
        payments made not less frequently than quarterly.

12.4 Administration of Loan Investment Fund

Upon approval of a loan to a Participant, the Administrator shall direct the
Trustee to transfer an amount equal to the

                                       38
<PAGE>   52

loan amount from the Investment Funds in which it is invested, as directed by
the Administrator, to the loan Investment Fund established by the Trustee in
the Participant's name. Any loan approved by the Administrator shall be made to
the Participant out of the Participant's loan Investment Fund. All principal and
interest paid by the Participant on a loan made under this Article shall be
deposited to his Separate Account and shall be allocated upon receipt among the
Investment Funds in accordance with the Participant's currently effective
investment election. The balance of the Participant's loan Investment Fund shall
be decreased by the amount of principal payments and the loan Investment Fund
shall be terminated when the loan has been repaid in full.

12.5 Default

If a Participant fails to make or cause to be made, any payment required under
the terms of the loan within 90 days following the date on which such payment
shall become due or there is an outstanding principal balance existing on a
loan after the last scheduled repayment date, the Administrator may direct the
Trustee to declare the loan to be in default, and the entire unpaid balance of
such loan, together with accrued interest, shall be immediately due and payable.
In any such event, if such balance and interest thereon is not then paid, the
Trustee shall charge the Separate Account of the borrower with the amount of
such balance and interest as of the earliest date a distribution may be made
from the Plan to the borrower without adversely affecting the tax
qualification of the Plan or of the cash or deferred arrangement.

12.6 Loans Granted Prior to October 19, 1989

Notwithstanding any other provision of this Article to the contrary, any loan
made under the provisions of the Plan as in effect prior to October 19, 1989
shall remain outstanding until repaid in accordance with its terms or the
otherwise applicable Plan provisions.

hardship as defined in Section 13.6 may elect in writing, subject to the
limitations and conditions prescribed in Section 13.4 or 13.6, as appropriate,
to make a cash withdrawal from his vested interest in his Employer Contributions
Sub-Account. The maximum amount that a Participant may withdraw pursuant to this

        X = P (AB + (R x D)) - (R x D)

        For purposes of the formula:

        P =     The Participant's vested interest in his Employer
                Contributions Sub-Account on the date distribution is to be
                made.

        AB=     The balance of the Participant's Employer Contributions
                Sub-Account as of the Valuation Date immediately preceding
                the date distribution is to be made.

        R =     The ratio of (i) the balance of the Participant's Employer
                Contributions Sub-Account as of the Valuation Date immediately
                preceding the date distribution is to be made (ii) the balance
                of the Participant's Employer Contribution Sub-Account after
                distribution is made.

        D =     The amount of all prior withdrawals from the Participant's

attained age 59 1/2 or is determined by the Administrator to have incurred a
hardship as defined in Section 13.6 may elect in writing, subject to the
limitations and conditions prescribed in Section 13.4 or 13.6, as appropriate,
to make a cash withdrawal from his Tax-Deferred Contributions Sub-Account. The
maximum amount that a Participant may withdraw pursuant to this Section because
of a hardship is the balance of his Tax-Deferred Contributions Sub-Account,
exclusive of any earnings credited to such Sub-Account as of a date that is
after December 31, 1988.

13.4 Limitations on withdrawals Other than Hardship Withdrawals

Withdrawals made pursuant to this Article; other than hardship withdrawals,
shall be subject to the following conditions and limitations:

        A Participant must file a written withdrawal application with the
        Administrator such number of days prior to the date as of which it is to
        be effective as the Administrator shall prescribe.

        Withdrawals may be made effective as soon as reasonably practicable
        following the Administrator's receipt of the Participant's directions.

13.5 Order of Withdrawal from a Participant's Sub-Accounts

Distribution of a withdrawal amount shall be made from a Participant's
Sub-Accounts, to the extent necessary, in the following order:

        The balance of the Participant's Rollover Contributions Sub-Account, if
        any, shall be distributed.

        The balanceof the Participant's Employer Contributions Sub-Account shall
        be distributed.

        The balance of the Participant's Tax-Deferred Contributions Sub-Account
        shall be distributed, but if the distribution is because of hardship,
        only to the extent permitted under Section 13.3.

If the Sub-Account from which a Participant is receiving a withdrawal is
invested in more than one Investment Fund, the withdrawal shall be charged
against the Investment Funds as

                                       41

directed by the Administrator.

13.6 Conditions and Limitations on Hardship Withdrawals

A Participant must file a written application for a hardship withdrawal with the
Administrator such number of days prior to the date as of which it is to be
effective as the Administrator may prescribe. Hardship withdrawals may be made
effective as soon as reasonably practicable following the Administrator's
receipt of the Participant's directions. The Administrator shall grant a
hardship withdrawal only if it determines that the withdrawal is necessary to
meet an immediate and heavy financial need of the Participant. An immediate and
heavy financial need of the Participant means a financial need on account of:

(a)     expenses previously incurred by or necessary to obtain for the
        Participant, the Participant's spouse, or any dependent of the
        Participant (as defined in Section 152 of the Code) medical care
        described in Section 213 (d) of the Code;

(b)     costs directly related to the purchase (excluding mortgage payments) of
        a principal residence for the Participant;

(c)     payment of tuition, related educational fees, and room and board
        expenses for the next 12 months of post-secondary education for the
        Participant, the Participant's spouse, or any dependent of the
        Participant; or

(d)     the need to prevent the eviction of the Participant from his principal
        residence or foreclosure on the mortgage of the Participant's principal
        residence.

A withdrawal shall be deemed to be necessary to satisfy an immediate and heavy
financial need of a Participant only if all of the following requirements are
satisfied:

        The withdrawal is not in excess of the amount of the immediate and
        heavy financial need of the Participant.

        The Participant has obtained all distributions, other than hardship
        distributions, and all non-taxable loans currently available under all
        plans maintained by an Employer or any Related Company.

        The Participant's Tax-Deferred Contributions and the Participant's
        elective tax-deferred contributions and employee after-tax contributions
        under all other

                                       42
<PAGE>   56

        tax-qualified plans maintained by an Employer or any Related Company
        shall be suspended for at least twelve months after his receipt of the
        withdrawal.

        The Participant shall not make Tax-Deferred Contributions or elective
        tax-deferred contributions under any other tax-qualified plan maintained
        by an Employer or any Related Company for the Participant's taxable year
        immediately following the taxable year of the withdrawal in excess of
        the applicable limit under Section 402 (g) of the Code for such next
        taxable year less the amount of the Participant's Tax-Deferred
        Contributions and elective tax-deferred contributions under any other
        plan maintained by an Employer or any Related Company for the taxable
        year of the withdrawal.

The minimum hardship withdrawal that a participant may make is $1,000. The
amount of a hardship withdrawal shall include any amounts necessary to pay any
Federal, state or local income taxes or penalties reasonably anticipated to
result from the distribution. A Participant shall not fail to be treated as an
Eligible Employee for purposes of applying the limitations contained in Article
VIII of the Plan merely because his Tax-Deferred Contributions are suspended in
accordance with this Section.

                                   ARTICLE XIV
                 TERMINATION OF EMPLOYMENT AND SETTLEMENT DATE

14.1 Termination of Employment and Settlement Date

A Participant's Settlement Date shall occur on the date he terminates employment
with an Employer and all Related Companies because of death, disability,
retirement, or other termination of employment. Written notice of a
Participant's Settlement Date shall be given by the Administrator to the
Trustee.

14.2 Separate Accounting for Non-Vested Amounts

If as of a Participant's Settlement Date the Participant's vested interest in
his Employer Contributions Sub-Account is less than 100 percent, that portion of
his Employer Contributions Sub-Account that is not vested shall be accounted for
separately from the vested portion and shall be disposed of as provided in
Section 14.3. If prior to his Settlement Date such a Participant made a
withdrawal in accordance with the provisions of Article XIII, the vested portion
of his Employer Contributions Sub-Account shall be equal to the maximum
withdrawable amount as determined under Article XIII attributable to Employer
Contributions that may be taken into account to satisfy the limitations on
contributions for Highly Compensated Employees contained in Article VII.

14.3 Disposition of Non-Vested Amounts

That portion of a Participant's Employer Contributions Sub-Account that is not
vested upon the occurrence of his Settlement Date shall be disposed of as
follows:

(a)     If the Participant has no vested interest in his Separate Account upon
        the occurrence of his Settlement Date or the aggregate value as of the
        date of distribution does not exceed $3,500 resulting in the
        Participant's receipt of a single sum payment of his vested interest in
        his Separate Account, the non-vested balance remaining in the
        Participant's Employer Contributions Sub-Account will be forfeited and
        his Separate Account closed as of (i) the Participant's Settlement
        Date, if the Participant has no vested interest in his Separate Account,
        or (ii) the date the single sum payment occurs.

(b)     If the aggregate value of the Participant's vested interest in his
        Separate Account exceeds $3,500 and

                                       44
<PAGE>   58

        the Participant is eligible for and consents in writing to a single sum
        payment of his vested interest in his Separate Account, the non-vested
        balance remaining in the Participant's Employer Contributions
        Sub-Account will be forfeited and his Separate Account closed as of the
        date the single sum payment occurs, provided that such distribution
        occurs prior to the end of the second Plan Year beginning on or after
        the Participant's Settlement Date.

(c)     If neither paragraph (a) nor paragraph (b) is applicable, the non-vested
        portion of the Participant's Employer Contributions Sub-Account will
        continue to be held in such Sub-Account and will not be forfeited until
        the end of the five-year period beginning on his Settlement Date.

Whenever the non-vested portion of a Participant's Employer Contributions
Sub-Account is forfeited under the provisions of the Plan with respect to a Plan
Year, the amount of such forfeiture, as of the last day of the Plan Year, shall
be applied against the Employer Contribution obligations for the Plan Year of
the Employer for which the Participant last performed services as an Employee.
Notwithstanding the foregoing, however, should the amount of all such
forfeitures for any Plan Year with respect to any Employer exceed the amount of
such Employer's Employer Contribution obligation for the Plan Year, the excess
amount of such forfeitures shall be held unallocated in a suspense account
established with respect to the Employer and shall for all Plan purposes be
applied against the Employer's Employer Contribution obligations for the
following Plan Year.

14.4 Recrediting of Forfeited Amounts

A former Participant who forfeited the non-vested portion of his Employer
Contributions Sub-Account in accordance with the provisions of Section 14.3 and
who is reemployed by an Employer or a Related Company shall have such forfeited
amounts recredited to a new Separate Account in his name, without adjustment for
interim gains or losses experienced by the Trust, if:

(a)     he returns to employment with an Employer or a Related Company before
        the end of the five-year period beginning on the later of his Settlement
        Date or the date he received distribution of his vested interest in his
        Separate Account;

(b)     he resumes employment covered under the Plan before

                                       45
<PAGE>   59

        the end of the five-year period beginning on the date he is reemployed;
        and

(c)     if he received distribution of his vested interest in his Separate
        Account, he repays to the Plan the full amount of such distribution
        before the end of the five-year period beginning on the date he is
        reemployed.

Funds needed in any Plan Year to recredit the Separate Account of a Participant
with the amounts of prior forfeitures in accordance with the preceding sentence
shall come first from forfeitures that arise during such Plan Year, and then
from Trust income earned in such Plan Year, with each Trust Fund being charged
with the amount of such income proportionately, unless his Employer chooses to
make an additional Employer Contribution, and shall finally be provided by his
Employer by way of a separate Employer Contribution.

                                   ARTICLE XV
                                 DISTRIBUTIONS

15.1 Distributions to Participants

A Participant whose Settlement Date occurs shall receive distribution of his
vested interest in his Separate Account in the form provided under Article XVI
beginning as soon as reasonably practicable following his Settlement Date or
the date his application for distribution is filed with the Administrator, if
later. In addition, a Participant who continues in employment with an Employer
or a Related Company after his Normal Retirement Date may elect to receive
distribution of all or any portion of his Separate Account in the form provided
under Article XVI at any time following his Normal Retirement Date.

15.2 Distributions to Beneficiaries

If a Participant dies prior to the date distribution of his vested interest in
his Separate Account begins under this Article, his Beneficiary shall receive
distribution of the Participant's vested interest in his Separate Account in the
form provided under Article XVI beginning as soon as reasonably practicable
following the date the Beneficiary's application for distribution is filed with
the Administrator. Unless distribution is to be made over the life or over
a period certain not greater than the life expectancy of the Beneficiary,
distribution of the Participant's entire vested interest shall be made to the
Beneficiary no later than the end of the fifth calendar year beginning after the
Participant's death. If distribution is to be made over the life or over a
period certain no greater than the life expectancy of the Beneficiary,
distribution shall commence no later than:

(a)     If the Beneficiary is not the Participant's spouse, the end of the first
        calendar year beginning after the Participant's death; or

(b)     If the Beneficiary is the Participant's spouse, the later of (i) the
        end of the first calendar year beginning after the Participant's death
        or (ii) the end of the calendar year in which the Participant would have
        attained age 70 1/2.

If distribution is to be made to a Participant's spouse, it shall be made
available within a reasonable period of time after the Participant's death that
is no less favorable than the period of time applicable to other distributions.
If a

                                       47
<PAGE>   61

Participant dies after the date distribution of his vested interest in his
Separate Account begins under this Article, but before his entire vested
interest in his Separate Account is distributed, his Beneficiary shall receive
distribution of the remainder of the Participant's vested interest in his
Separate Account beginning as soon as reasonably practicable following the
Participant's date of death in a form that provides for distribution at least
as rapidly as under the form in which the Participant was receiving
distribution.

15.3 Cash Outs and Participant Consent

Notwithstanding any other provision of the Plan to the contrary, if a
Participant's vested interest in his Separate Account does not exceed $3,500,
distribution of such vested interest shall be made to the Participant in a
single sum payment as soon as reasonably practicable following his Settlement
Date. If a Participant's vested interest in his Separate Account exceeds
$3,500, distribution shall not commence to such Participant prior to his Normal
Retirement Date without the Participant's written consent. If a Participant made
a withdrawal in accordance with the provisions of Article XIII or was in default
on a loan for which a portion of his Separate Account was pledged as security as
provided in Article XII and his vested interest in his Separate Account on the
date immediately preceding the withdrawal or default exceeded $3,500, then for
purposes of this Section, his vested interest in his Separate Account shall be
deemed to exceed $3,500.

15.4 Required Commencement of Distribution

Notwithstanding any other provision of the Plan to the contrary, distribution of
a Participant's vested interest in his Separate Account shall commence to the
Participant no later than the earlier of:

(a)     60 days after the close of the Plan Year in which (i) the Participant's
        Normal Retirement Date occurs, (ii) the tenth anniversary of the year in
        which he commenced participation in the Plan occurs, or (iii) his
        Settlement Date occurs, whichever is latest; or

(b)     the April 1 following the close of the calendar year in which he attains
        age 70 1/2, whether or not his Settlement Date has occurred, except
        that if a Participant attained age 70 1/2 prior to January 1, 1988, and
        was not a five-percent owner (as defined in Section 416 of the Code) at
        any time during the five-Plan-Year period ending within the calendar
        year

                                       48
<PAGE>   62

        in which he attained age 70 1/2, distribution of such Participant's
        vested interest in his Separate Account shall commence no later than
        the April 1 following the close of the calendar year in which he
        attains age 70 1/2 or retires, whichever is later.

Distributions required to commence under this Section shall be made in the form
provided under Article XVI and in accordance with Section 401(a)(9) of the
Code and regulations issued thereunder, including the minimum distribution
incidental benefit requirements.

15.5 Reemployment of a Participant

If a Participant whose Settlement Date has occurred is reemployed by an Employer
or a Related Company, he shall lose his right to any distribution or further
distributions from the Trust arising from his prior Settlement Date and his
interest in the Trust shall thereafter be treated in the same manner as that of
any other Participant whose Settlement Date has not occurred.

15.6 Restrictions on Alienation

Except as provided in Section 401(a)(13) of the Code relating to qualified
domestic relations orders and Section 1.401(a)-13(b)(2) of Treasury regulations
relating to Federal tax levies and judgments, no benefit under the Plan at any
time shall be subject in any manner to anticipation, alienation, assignment
(either at law or in equity), encumbrance, garnishment, levy, execution, or
other legal or equitable process; and no person shall have power in any manner
to anticipate, transfer, assign (either at law or in equity), alienate or
subject to attachment, garnishment, levy, execution, or other legal or equitable
process, or in any way encumber his benefits under the Plan, or any part
thereof, and any attempt to do so shall be void.

15.7 Facility of Payment

If the Administrator finds that any individual to whom an amount is payable
hereunder is incapable of attending to his financial affairs because of any
mental or physical condition, including the infirmities of advanced age, such
amount (unless prior claim therefor shall have been made by a duly qualified
guardian or other legal representative) may, in the discretion of the
Administrator, be paid to another person for the use or benefit of the
individual found incapable of attending to his financial affairs or in
satisfaction of legal obligations incurred by or on behalf of such individual.
The Trustee shall make such payment

                                       49
<PAGE>   63

only upon receipt of written instructions to such effect from the Administrator.
Any such payment shall be charged to the Separate Account from which any such
payment would otherwise have been paid to the individual found incapable of
attending to his financial affairs and shall be a complete discharge of any
liability therefor under the Plan.

15.8 Inability to Locate Payee

If any benefit becomes payable to any person, or to the executor or
administrator of any deceased person, and if that person or his executor or
administrator does not present himself to the Administrator within five years
after the Administrator mails written notice of his eligibility to receive a
distribution hereunder to his last known address, that benefit will be
forfeited. However, if the payee later files a claim for that benefit, the
benefit will be restored.

15.9 Distribution Pursuant to Qualified Domestic Relations Orders

Notwithstanding any other provision of the Plan to the contrary, if a qualified
domestic relations order so provides, distribution may be made to an alternate
payee pursuant to a qualified domestic relations order, as defined in Section
414(p) of the Code, regardless of whether the Participant's Settlement Date has
occurred or whether the Participant is otherwise entitled to receive a
distribution under the Plan.

                                FORM OF PAYMENT

16.1 Form of Payment

Distribution shall be made to a Participant, or his Beneficiary, if the
Participant has died, in a single sum payment. Notwithstanding the foregoing, if
a Participant continues in employment with an Employer or a Related Company
after the date as of which distribution of his vested interest must commence in
accordance with the requirements of Section 401(a)(9) of the Code, such
Participant may elect to receive distribution in periodic payments, made not
less frequently than annually, equal to the minimum amount necessary to satisfy
the distribution requirements of Section 401(a)(9) of the Code and regulations
issued thereunder for the remainder of the period that he continues in
employment with an Employer or a Related Company. Distribution shall be made in
cash or in kind at the Participant's, or his Beneficiary's, election.

16.2 Direct Rollover

Notwithstanding any other provision of the Plan to the contrary, in lieu of
receiving distribution in the form of payment provided under this Article, a
"qualified distributee" may elect in writing, in accordance with rules
prescribed by the Administrator, to have any portion or all of a distribution
made on or after January 1, 1993, that is an "eligible rollover distribution"
paid directly by the Plan to the "eligible retirement plan" designated by the
"qualified distributee"; provided, however, that this provision shall not apply
if the total distribution is less than $200 and that a "qualified distributee"
may not elect this provision with respect to a portion of a distribution that is
less than $500. Any such payment by the Plan to another "eligible retirement
plan" shall be a direct rollover. For purposes of this Section, the following
terms have the following meanings:

(a)     An "eligible retirement plan" means an individual retirement account
        described in Section 408(a) of the Code, an individual retirement
        annuity described in section 408(b) of the Code, an annuity plan
        described in Section 403(a) of the Code, or a qualified trust described
        in Section 401(a) of the Code that accepts rollovers; provided, however,
        that, in the case of a direct rollover by a surviving spouse, an
        eligible retirement plan does not include a qualified trust described in
        Section 401(a) of the Code.

                                       51
<PAGE>   65

(b)     An "eligible rollover distribution" means any distribution of all or any
        portion of the balance of a Participant's Separate Account; provided,
        however, that an eligible rollover distribution does not include any
        distribution to the extent such distribution is required under Section
        401(a)(9) of the Code.

(c)     A "qualified distributee" means a Participant, his surviving spouse, or
        his spouse or former spouse who is an alternate payee under a qualified
        domestic relations order, as defined in Section 414(p) of the Code.

16.3 Notice Regarding Form of Payment

Within the 60 day period ending 30 days before the date as of which
distribution of a Participant's Separate Account commences, the Administrator
shall provide the Participant with a written explanation of his right to defer
distribution until his Normal Retirement Date, his right to make a direct
rollover, and the form of payment provided under the Plan. Distribution of the
Participant's Separate Account may commence less than 30 days after such notice
is provided to the Participant if (i) the Administrator clearly informs the
Participant of his right to consider his election of whether or not to make a
direct rollover or to receive a distribution prior to his Normal Retirement
Date for a period of at least 30 days following his receipt of the notice and
(ii) the Participant, after receiving the notice, affirmatively elects an early
distribution.

                                 BENEFICIARIES

17.1 Designation of Beneficiary

A married Participant's Beneficiary shall be his spouse, unless the Participant
designates a person or persons other than his spouse as Beneficiary with his
spouse's written consent. A Participant may designate a Beneficiary on the form
prescribed by the Administrator. If no Beneficiary has been designated pursuant
to the provisions of this Section, or if no Beneficiary survives the Participant
and he has no surviving spouse, then the Beneficiary under the Plan shall be the
Participant's estate. If a Beneficiary dies after becoming entitled to receive a
distribution under the Plan but before distribution is made to him in full, and
if no other Beneficiary has been designated to receive the balance of the
distribution in that event, the estate of the deceased Beneficiary shall be the
Beneficiary as to the balance of the distribution.

17.2 Spousal Consent Requirements

Any written spousal consent given pursuant to this Article must acknowledge the
effect of the action taken and must be witnessed by a Plan representative or a
notary public. The spouse's written consent may be a general consent that
permits the Participant to change the designated Beneficiary without the
spouse's further consent. A Participant's spouse will be deemed to have given
written consent to the Participant's designation of Beneficiary if the
Participant establishes to the satisfaction of a Plan representative that such
consent cannot be obtained because the spouse cannot be located or because of
other circumstances set forth in Section 401(a)(11) of the Code and regulations
issued thereunder. Any written consent given or deemed to have been given by a
Participant's spouse hereunder shall be valid only with respect to the spouse
who signs the consent.

                                 ADMINISTRATION

18.1 Authority of the Sponsor

The Sponsor, which shall be the administrator for purposes of ERISA and the plan
administrator for purposes of the Code, shall be responsible for the
administration of the Plan and, in addition to the powers and authorities
expressly conferred upon it in the Plan shall have all such powers and
authorities as may be necessary to carry out the provisions of the Plan,
including the power and authority to interpret and construe the provisions of
the Plan, to make benefit determinations, and to resolve any disputes which
arise under the Plan. The Sponsor may employ such attorneys, agents, and
accountants as it may deem necessary or advisable to assist in carrying out its
duties hereunder. The Sponsor and the Trustee shall be "named fiduciaries" as
that term is defined in Section 402(a)(2) of ERISA. The Sponsor may:

(a)     allocate any of the powers, authority, or responsibilities for the
        operation and administration of the Plan, which are retained by it or
        granted to it by this Article, to the Trustee; and

(b)     designate a person or persons other than the Sponsor to carry out any
        of such powers, authority, or responsibilities;

except that no power, authority, or responsibility of the Trustee shall be
subject to the provisions of paragraph (b) of this Section, and except that no
allocation or delegation by the Sponsor of any of its powers, authority, or
responsibilities to the Trustee shall become effective unless such allocation or
delegation shall first be accepted by the Trustee in a writing signed by it and
delivered to the Sponsor.

18.2 Action of the Sponsor

Any act authorized, permitted, or required to be taken under the Plan by the
Sponsor and which has not been delegated in accordance with Section 18.1, may be
taken by a majority of the members of the board of directors of the Sponsor,
either by vote at a meeting, or in writing without a meeting, or by the employee
or employees of the Sponsor designated by the board of directors to carry out
such acts on behalf of the Sponsor. All notices, advice, directions,
certifications, approvals, and instructions required or authorized to be

                                       54
<PAGE>   68

given by the Sponsor as under the Plan shall be in writing and signed by either
(i) a majority of the members of the board of directors of the Sponsor or by
such member or members as may be designated by an instrument in writing, signed
by all the members thereof, as having authority to, execute such documents on
its behalf, or (ii) the employee or employees authorized to act for the Sponsor
in accordance with the provisions of this Section.

18.3 Claims Review Procedure

Whenever a claim for benefits under the Plan filed by any person (herein
referred to as the "Claimant") is denied, whether in whole or in part, the
Sponsor shall transmit a written notice of such decision to the Claimant within
90 days of the date the claim was filed or, if special circumstances require an
extension, within 180 days of such date, which notice shall be written in a
manner calculated to be understood by the Claimant and shall contain a statement
of (i) the specific reasons for the denial of the claim, (ii) specific reference
to pertinent Plan provisions on which the denial is based, and (iii) a
description of any additional material or information necessary for the
Claimant to perfect the claim and an explanation of why such information is
necessary. The notice shall also include a statement advising the Claimant that,
within 60 days of the date on which he receives such notice, he may obtain
review of such decision in accordance with the procedures hereinafter set forth.
Within such 60-day period, the Claimant or his authorized representative may
request that the claim denial be reviewed by filing with the Sponsor a written
request therefor, which request shall contain the following information:

(a)     the date on which the Claimant's request was filed with the Sponsor;
        provided, however, that the date on which the Claimant's request for
        review was in fact filed with the Sponsor shall control in the event
        that the date of the actual filing is later than the date stated by the
        Claimant pursuant to this paragraph;

(b)     the specific portions of the denial of his claim which the Claimant
        requests the Sponsor to review;

(c)     a statement by the Claimant setting forth the basis upon which he
        believes the Sponsor should reverse the previous denial of his claim for
        benefits and accept his claim as made; and

(d)     any written material (offered as exhibits) which the

                                       55

        Claimant desires the Sponsor to examine in its consideration of his
        position as stated pursuant to paragraph (c) of this Section.

Within 60 days of the date determined pursuant to paragraph (a) of this Section
or, if special circumstances require an extension, within 120 days of such date,
the Sponsor shall conduct a full and fair review of the decision denying the
Claimant's claim for benefits and shall render its written decision on review to
the Claimant. The Sponsor's decision on review shall be written in a manner
calculated to be understood by the Claimant and shall specify the reasons and
Plan provisions upon which the Sponsor's decision was based.

18.4 Qualified Domestic Relations Orders

The Sponsor shall establish reasonable procedures to determine the status of
domestic relations orders and to administer distributions under domestic
relations orders which are deemed to be qualified orders. Such procedures shall
be in writing and shall comply with the provisions of Section 414(p) of the
Code and regulations issued thereunder.

18.5 Indemnification

In addition to whatever rights of indemnification the Trustee or the members of
the board of directors of the Sponsor or any employee or employees of the
Sponsor to whom any power, authority, or responsibility is delegated pursuant to
Section 18.2, may be entitled under the articles of incorporation or regulations
of the Sponsor, under any provision of law, or under any other agreement, the
Sponsor shall satisfy any liability actually and reasonably incurred by any such
person or persons, including expenses, attorneys' fees, judgments, fines, and
amounts paid in settlement (other than amounts paid in settlement not approved
by the Sponsor), in connection with any threatened, pending or completed action,
suit, or proceeding which is related to the exercising or failure to exercise by
such person or persons of any of the powers, authority, responsibilities, or
discretion as provided under the Plan, or reasonably believed by such person or
persons to be provided hereunder, and any action taken by such person or persons
in connection therewith, unless the same is judicially determined to be the
result of such person's or persons' gross negligence or willful misconduct.

18.6 Actions Binding

Subject to the provisions of Section 18.3, any action taken by the Sponsor which
is authorized, permitted, or required

                                       56
<PAGE>   70

under the Plan shall be final and binding upon the Employers, the Trustee, all
persons who have or who claim an interest under the Plan, and all third parties
dealing with the Employers or the Trustee.

                                   ARTICLE XIX
                           AMENDMENT AND TERMINATION

19.1 Amendment

Subject to the provisions of Section 19.2, the Sponsor may at any time and from
time to time, by action of its board of directors, or such officers of the
Sponsor as are authorized by its board of directors, amend the Plan, either
prospectively or retroactively. Any such amendment shall be by written
instrument executed by the Sponsor.

19.2 Limitation on Amendment

The Sponsor shall make no amendment to the Plan which shall decrease the accrued
benefit of any Participant or Beneficiary, except that nothing contained herein
shall restrict the right to amend the provisions of the plan relating to the
administration of the Plan and Trust. Moreover, no such amendment shall be made
hereunder which shall permit any part of the Trust to revert to an Employer or
any Related Company or be used or be diverted to purposes other than the
exclusive, benefit of Participants and Beneficiaries.

19.3 Termination

The Sponsor reserves the right, by action of its board of directors, to
terminate the Plan as to all Employers at any time (the effective date of such
termination being hereinafter referred to as the "termination date"). Upon any
such termination of the Plan, the following actions shall be taken for the
benefit of Participants and Beneficiaries:

(a)     As of the termination date, each Investment Fund shall be valued and all
        Separate Accounts and Sub-Accounts shall be adjusted in the manner
        provided in Article XI, with any unallocated contributions or
        forfeitures being allocated as of the termination date in the manner
        otherwise provided in the Plan. The termination date shall become a
        Valuation Date for purposes of Article XI. In determining the net worth
        of the Trust, there shall be included as a liability such amounts as
        shall be necessary to pay all expenses in connection with the
        termination of the Trust and the liquidation and distribution of the
        property of the Trust, as well as other expenses, whether or not
        accrued, and shall include as an asset all accrued income.

                                       58
<PAGE>   72

(b)     All Separate Accounts shall then be disposed of to or for the benefit of
        each Participant or Beneficiary in accordance with the provisions of
        Article XV as if the termination date were his Settlement Date;
        provided, however, that notwithstanding the provisions of Article XV, if
        the Plan does not offer an annuity option and if neither his Employer
        nor a Related Company establishes or maintains another defined
        contribution plan (other than an employee stock ownership plan as
        defined in Section 4975(e)(7) of the Code), the Participant's written
        consent to the commencement of distribution shall not be required
        regardless of the value of the Participant's vested interest in his
        Separate Account.

(c)     Notwithstanding the provisions of paragraph (b) of this Section, no
        distribution shall be made to a Participant of any portion of the
        balance of his Tax-Deferred Contributions Sub-Account prior to his
        separation from service (other than a distribution made in accordance
        with Article XIII or required in accordance with Section 401(a)(9) of
        the Code) unless (i) neither his Employer nor a Related Company
        establishes or maintains another defined contribution plan (other than
        an employee stock ownership plan as defined in Section 4975(e)(7) of
        the Code, a tax credit employee stock ownership plan as defined in
        Section 409 of the Code, or a simplified employee pension as defined in
        Section 408(k) of the Code) either at the time the plan is terminated
        or at any time during the period ending 12 months after distribution of
        all assets from the Plan; provided, however, that this provision shall
        not apply if fewer than two percent of the Eligible Employees under the
        Plan were eligible to participate at any time in such other defined
        contribution plan during the 24-month period beginning 12 months before
        the Plan termination, and (ii) the distribution the Participant receives
        is a "lump sum distribution" as defined in Section 402(e)(4) of the
        Code, without regard to clauses (i), (ii), (iii), and (iv) of
        sub-paragraph (A), sub-paragraph (B), or sub-paragraph (H) thereof.

Notwithstanding anything to the contrary contained in the Plan, upon any such
Plan termination, the vested interest of each Participant and Beneficiary in his
Employer Contributions Sub-Account shall be 100 percent; and, if there is a
partial termination of the Plan, the vested interest of each Participant and
Beneficiary who is affected by the partial termination in his Employer
Contributions

                                       59
<PAGE>   73

Sub-Account shall be 100 percent. For purposes of the preceding sentence only,
the Plan shall be deemed to terminate automatically if there shall be a complete
discontinuance of contributions hereunder by all Employers.

19.4 Reorganization

The merger, consolidation, or liquidation of any Employer with or into any other
Employer or a Related Company shall not constitute a termination of the Plan as
to such, Employer. If an Employer disposes of substantially all of the assets
used by the Employer in a trade or business or disposes of a subsidiary and in
connection therewith one or more Participants terminates employment but
continues in employment with the purchaser of the assets or with such
subsidiary, no distribution from the Plan shall be made to any such Participant
prior to his separation from service (other than a distribution made in
accordance with Article XIII or required in accordance with Section 401(a)(9) of
the Code), except that a distribution shall be permitted to be made in such a
case, subject to the Participant's consent (to the extent required by law), if
(i) the distribution would constitute a "lump sum distribution" as defined in
section 402(e)(4) of the Code, without regard to clauses (i), (ii), (iii), or
(iv) of sub-paragraph (A), sub-paragraph (B), or sub-paragraph (H) thereof, (ii)
the Employer continues to maintain the Plan after the disposition, (iii) the
purchaser does not maintain the Plan after the disposition, and (iv) the
distribution is made by the end of the second calendar year after the calendar
year in which the disposition occurred.

19.5 Withdrawal of an Employer

An Employer other than the Sponsor may withdraw from the Plan at any time upon
notice in writing to the Administrator (the effective date of such withdrawal
being hereinafter referred to as the "withdrawal date"), and shall thereupon
cease to be an Employer for all purposes of the Plan. An Employer shall be
deemed automatically to withdraw from the Plan in the event of its complete
discontinuance of contributions, or, subject to Section 19.4 and unless the
Sponsor otherwise directs, it ceases to be a Related Company of the Sponsor or
any other Employer. The withdrawal of an Employer shall be treated as a
termination of the Plan with respect to Participants who at the time are
employed by such Employer. In the event of any such withdrawal of an Employer,
the action specified in Section 19.3 shall be taken as of the withdrawal date,
as on a termination of the Plan, but with respect only to Participants who are
employed solely by the withdrawing Employer, and who, upon such withdrawal, are
neither transferred to nor continued in

                                       60
<PAGE>   74

employment with any other Employer or a Related Company. The interest of any
Participant employed by the withdrawing Employer who is transferred to or
continues in employment with any other Employer or a Related Company, and the
interest of any Participant employed solely by an Employer or a Related Company
other than the withdrawing Employer, shall remain unaffected by such withdrawal;
no adjustment to his Separate Accounts shall be made by reason of the
withdrawal; and he shall continue as a Participant hereunder subject to the
remaining provisions of the Plan.

                          ADOPTION BY OTHER EMPLOYERS

20.1 Adoption by Related Companies

A Related Company that is not an Employer may, with the consent of the Sponsor,
adopt the Plan and become an Employer hereunder by causing an appropriate
written instrument evidencing such adoption to be executed in accordance with
the requirements of its organizational authority. Any such instrument shall
specify the effective date of the adoption.

20.2 Effective Plan Provisions

An Employer who adopts the Plan shall be bound by the provisions of the Plan in
effect at the time of the adoption and as subsequently in effect because of any
amendment to the Plan.

                                   ARTICLE XXI
                            MISCELLANEOUS PROVISIONS

21.1 No Commitment as to Employment

Nothing contained herein shall be construed as a commitment or agreement upon
the part of any person to continue his employment with an Employer or Related
Company, or as a commitment on the part of any Employer or Related Company to
continue the employment, compensation, or benefits of any person for any period.

21.2 Benefits

Nothing in the Plan nor the Trust Agreement shall be construed to confer any
right or claim upon any person, firm, or corporation other than the Employers,
the Trustee, Participants, and Beneficiaries.

21.3 No Guarantees

The Employers, the Administrator, and the Trustee do not guarantee the Trust
from loss or depreciation, nor do they guarantee the payment of any amount which
may become due to any person hereunder.

21.4 Expenses

The expenses of administration of the Plan, including the expenses of the
Administrator and fees of the Trustee, shall be paid from the Trust or by the
Sponsor or another Employer as the Sponsor shall direct. Notwithstanding the
foregoing, administrative expenses that are allocable to the Separate Account of
a specific Participant shall be paid from that Separate Account or by the
Sponsor or another Employer as the Sponsor shall direct.

21.5 Precedent

Except as otherwise specifically provided, no action taken in accordance with
the Plan shall be construed or relied upon as a precedent for similar action
under similar circumstances.

21.6 Duty to Furnish Information

The Employers, the Administrator, and the Trustee shall furnish to any of the
others any documents, reports, returns, statements, or other information that
the other

                                       63
<PAGE>   77

reasonably deems necessary to perform its duties hereunder or otherwise imposed
by law.

21.7 Withholding

The Trustee shall withhold any tax which by any present or future later is
required to be withheld, and which the Administrator notifies the Trustee in
writing is to be so withheld, from any payment to any Participant or Beneficiary
hereunder.

21.8 Merger, Consolidation, or Transfer of Plan Assets

The Plan shall not be merged or consolidated with any other plan, nor shall any
of its assets or liabilities be transferred to another plan, unless, immediately
after such merger, consolidation, or transfer of assets or liabilities, each
Participant in the Plan would receive a benefit under the Plan which is at least
equal to the benefit he would have received immediately prior to such merger,
consolidation, or transfer of assets or liabilities (assuming in each instance
that the Plan had then terminated).

21.9 Back Pay Awards

The provisions of this Section shall apply only to an Employee or former
Employee who becomes entitled to back pay by an award or agreement of an
Employer without regard to mitigation of damages. If a person to whom this
Section applies was or would have become an Eligible Employee after such back
pay award or agreement has been effected, and if any such person who had not
previously elected to make Tax-Deferred. Contributions pursuant to Section 4.1
shall within 30 days of the date he receives notice of the provisions of this
Section make an election to make Tax-Deferred Contributions in accordance with
such Section 4.1 (retroactive to any Enrollment Date as of which he was or has
become eligible to do so), then such Participant may elect that any Tax-Deferred
Contributions not previously made on his behalf but which, after application of
the foregoing provisions of this Section, would have been made under the
provisions of Article IV, shall be made out of the proceeds of such back pay
award or agreement. In addition, if any such Employee or former Employee would
have been eligible to participate in the allocation of Employer Contributions
under the provisions of Article VI for any prior Plan Year after such back pay
award or agreement has been effected, his Employer shall make an Employer
Contribution equal to the amount of the Employer Contribution which would have
been allocated to such

                                       64
<PAGE>   78

Participant under the provisions of Article VI as in effect during each such
Plan Year. The amounts of such additional contributions shall be credited to
the Separate Account of such Participant. Any additional contributions made by
such Participant and by an Employer pursuant to this Section shall be made in
accordance with, and subject to the. limitations of the applicable provisions of
Articles IV, VI, and VII.

21.10 Condition on Employer Contributions

Notwithstanding anything to the contrary contained in the Plan or the Trust
Agreement, any contribution of an Employer hereunder is conditioned upon the
continued qualification of the Plan under Section 401(a) of the Code, the exempt
status of the Trust under Section 501 (a) of the Code, and the deductibility of
the contribution under Section 404 of the Code. Except as otherwise provided in
this Section and Section 21.11, however, in no event shall any portion of the
property of the Trust ever revert to or otherwise inure to the benefit of an
Employer or any Related Company.

21.11 Return of Contributions to an Employer

Notwithstanding any other provision of the Plan or the Trust Agreement to the
contrary, in the event any contribution of an Employer made hereunder:

(a)     is made under a mistake of fact, or

(b)     is disallowed as a deduction under Section 404 of the Code,

such contribution may be returned to the Employer within one year after the
payment of the contribution or the disallowance of the deduction to the extent
disallowed, whichever is applicable. In the event the Plan does not initially
qualify under Section 401(a) of the Code, any contribution of an Employer made
hereunder may be returned to the Employer within one year of the date of denial
of the initial qualification of the Plan, but only if an application for
determination was made within the period of time prescribed under Section 403
(c) (2) (13) of ERISA.

21.12 Validity of Plan

The validity of the Plan shall be determined and the Plan shall be construed and
interpreted in accordance with the laws of the Commonwealth of Massachusetts,
except as preempted by applicable Federal law. The invalidity or illegality of
any provision of the Plan shall not affect the

                                       65
<PAGE>   79

legality or validity of any other part thereof.

21.13 Trust Agreement

The Trust Agreement and the Trust maintained thereunder shall be deemed to be a
part of the Plan as-if fully set forth herein and the provisions of the Trust
Agreement are hereby incorporated by reference into the Plan.

21.14 Parties Bound

The Plan shall be binding upon the Employers, all Participants and Beneficiaries
hereunder, and, as the case may be, the heirs, executors, administrators,
successors, and assigns of each of them.

21.15 Application of Certain Plan Provisions

A Participant's Beneficiary, if the Participant has died, or alternate payee
under a qualified domestic relations order shall be treated as a Participant for
purposes of directing investments as provided in Article X. For purposes of the
general administrative provisions and limitations of the Plan, a Participant's
Beneficiary or alternate payee under a qualified domestic relations order shall
be treated as any other person entitled to receive benefits under the Plan. Upon
any termination of the Plan, any such Beneficiary or alternate payee under a
qualified domestic relations order who has an interest under the Plan at the
time of such termination, which does not cease by reason thereof, shall be
deemed to be a Participant for all purposes of the Plan.

21.16 Leased Employees

Any leased employee, other than an excludable leased employee, shall be treated
as an employee of the Employer for which he performs services for all purposes
of the Plan with respect to the provisions of Sections 401 (a) (3), (4), (7),
and (16), and 408 (k), 410, 411,415, and 416 of the Code; provided, however,
that no leased employee shall accrue a benefit hereunder based on service as a
leased employee except as otherwise specifically provided in the Plan. A "leased
employee" means any person who performs services for an Employer or a Related
Company (the "recipient") (other than an employee of the recipient) pursuant to
an agreement between the recipient and any other person (the "leasing
organization") on a substantially full time basis for a period of at least one
year, provided that such services are of a type historically performed, in the
business field of the recipient, by employees. An "excludable leased employee"
means any leased employee of

                                       66
<PAGE>   80

the recipient who is covered by a money purchase pension plan maintained by the
leasing organization which provides for (i) a nonintegrated employer
contribution on behalf of each participant in the plan equal to at least ten
percent of compensation, (ii) full and immediate vesting, and (iii) immediate
participation by employees of the leasing organization (other than employees who
perform substantially, all of their services for the leasing organization or
whose compensation from the leasing organization in each plan year during the
four-year period ending with the plan year is less than $1,000); provided,
however, that leased employees do not constitute more than 20 percent of the
recipient's nonhighly compensated work force. For purposes of this Section,
contributions or benefits provided to a leased employee by the leasing
organization that are attributable to services performed for the recipient shall
be treated as provided by the recipient.

21.17 Transferred Funds

If funds from another qualified plan are transferred or merged into the Plan,
such funds shall be held and administered in accordance with any restrictions
applicable to them under such other plan to the extent required by law and shall
be accounted for separately to the extent necessary to accomplish the foregoing.

                                       67

                                  ARTICLE XXII
                              TOP-HEAVY PROVISIONS

22.1 Definitions

For purposes of this Article, the following terms have the following meanings:

(a)     The "compensation" of an employee means compensation as defined in
        Section 415 of the Code and regulations issued thereunder. In no
        event, however, shall the compensation of a Participant taken into
        account under the Plan for any Plan Year exceed (1) $200,000 for Plan
        Years beginning prior to January 1, 1994, or (2) $150,000 for Plan Years
        beginning on or after January 1, 1994 (subject to adjustment annually as
        provided in Section 401(a)(17)(B) and Section 415(d) of the Code;
        provided, however, that the dollar increase in effect on January 1 of
        any calendar year, if any, is effective for Plan Years beginning in such
        calendar year). If the compensation of a Participant is determined over
        a period of time that contains fewer than 12 calendar months, then the
        annual compensation limitation described above shall be adjusted with
        respect to that Participant by multiplying the annual compensation
        limitation in effect for the Plan Year by a fraction the numerator of
        which is the number of full months in the period and the denominator of
        which is 12; provided, however, that no proration is required for a
        Participant who is covered under the Plan for less than one full Plan
        Year if the formula for allocations is based on Compensation for a
        period of at least 12 months. In determining the compensation, for
        purposes of applying the annual compensation limitation described above,
        of a Participant who is a five-percent owner or one of the ten Highly
        Compensated Employees receiving the greatest compensation for the Plan
        Year, the compensation of the Participant's spouse and of his lineal
        descendants who have not attained age 19 as of the close of the Plan
        Year shall be included as compensation of the Participant for the Plan
        Year. If as a result of applying the family aggregation rule described
        in the preceding sentence the annual compensation limitation would be
        exceeded, the limitation shall be prorated among the affected family
        members in proportion to each member's compensation as determined prior
        to application of the family aggregation rules.

                                       68
<PAGE>   82

(b)     The "determination date" with respect to any Plan Year means the last
        day of the preceding Plan Year, except that the determination date with
        respect to the first Plan Year of the Plan, shall mean the last day of
        such Plan Year.

(c)     A "key employee" means any Employee or former Employee who is a key
        employee pursuant to the provisions of Section 416(i)(1) of the Code and
        any Beneficiary of such Employee or former Employee.

(d)     A "non-key employee" means any Employee who is not a key employee.

(e)     A "permissive aggregation group" means those plans included in each
        Employer's required aggregation group together with any other plan or
        plans of the Employer, so long as the entire group of plans would
        continue to meet the requirements of Sections 401(a)(4) and 410 of the
        Code.

(f)     A "required aggregation group" means the group of tax qualified plans
        maintained by an Employer or a Related Company consisting of each plan
        in which a key employee participates and each other plan that enables a
        plan in which a key employee participates to meet the requirements of
        Section 401(a)(4) or Section 410 of the Code, including any plan that
        terminated within the five-year period ending on the relevant
        determination date.

(g)     A "super top-heavy group" with respect to a particular Plan Year means a
        required or permissive aggregation group that, as of the determination
        date, would qualify as a top-heavy group under the definition in
        paragraph (i) of this Section with "90 percent" substituted for "60
        percent" each place where "60 percent" appears in the definition.

(h)     A "super top-heavy plan" with respect to a particular Plan Year means a
        plan that, as of the determination date, would qualify as a top-heavy
        plan under the, definition in paragraph (j) of this Section with "90
        percent" substituted for "60 percent" each place where "60 percent"
        appears in the definition. A plan is also a "super top-heavy plan" if it
        is part of a super top-heavy group.

(i)     A "top-heavy group" with respect to a particular Plan Year means a
        required or permissive aggregation group if the sum, as of the
        determination date, of the

                                       69
<PAGE>   83

        present value of the cumulative accrued benefits for key employees under
        all defined benefit plans included in such group and the aggregate of
        the account balances of key employees under all defined contribution
        plans included in such group exceeds 60 percent of a similar sum
        determined for all employees covered by the plans included in such
        group.

(j)     A "top-heavy plan" with respect to a particular Plan Year means (i), in
        the case of a defined contribution plan (including any simplified
        employee pension plan), a plan for which, as of the determination date,
        the aggregate of the accounts (within the meaning of Section 416(g) of
        the Code and the regulations and rulings thereunder) of key employees
        exceeds 60 percent of the aggregate of the accounts of all participants
        under the plan, with the accounts valued as of the relevant valuation
        date and increased for any distribution of an account balance made in
        the five-year period ending on the determination date, (ii), in the case
        of a defined benefit plan, a plan for which, as of the determination
        date, the present value of the cumulative accrued benefits payable under
        the plan (within the meaning of Section 416(g) of the Code and the
        regulations and rulings thereunder) to key employees exceeds 60 percent
        of the present value of the cumulative accrued benefits under the plan
        for all employees, with the present value of accrued benefits to be
        determined under the accrual method uniformly used under all plans
        maintained by an Employer or, if no such method exists, under the
        slowest accrual method permitted under the fractional accrual rate of
        Section 411(b)(1)(C) of the Code and including the present value of
        any part of any accrued benefits distributed in the five-year period
        ending on the determination date, and (iii) any plan (including any
        simplified employee pension plan) included in a required aggregation
        group that is a top-heavy group. For purposes of this paragraph, the
        accounts and accrued benefits of any employee who has not performed
        services for an Employer or a Related Company during the five-year
        period ending on the determination date shall be disregarded. For
        purposes of this paragraph, the present value of cumulative accrued
        benefits under a defined benefit plan for purposes of top-heavy
        determinations shall be calculated using the actuarial assumptions
        otherwise employed under such plan, except that the same actuarial
        assumptions shall be used for all plans within a required or permissive
        aggregation group. A Participant's interest in the Plan

        attributable to any Rollover Contributions, except Rollover
        Contributions made from a plan maintained by an Employer or a Related
        Company, shall not be considered in determining whether the Plan is
        top-heavy. Notwithstanding the foregoing, if a plan is included in a
        require or permissive aggregation group that is not a top-heavy group,
        such plan shall not be a top-heavy plan.

(k)     The "valuation date" with respect to any determination date means the
        most recent Valuation Date occurring within the 12-month period ending
        on the determination date.

22.2 Applicability

Notwithstanding any other provision of the Plan to the contrary, the provisions
of this Article shall be applicable during any Plan Year in which the Plan is
determined to be a top-heavy plan as hereinafter defined. If the Plan is
determined to be a top-heavy plan and upon a subsequent determination date is
determined no longer to be a top-heavy plan, the vesting provisions of Article
VI shall again become applicable as of such subsequent determination date;
provided, however, that if the prior vesting provisions do again become
applicable, any Employee with three or more years of Vesting Service may elect
in accordance with the provisions of Article VI, to continue to have his vested
interest in his Employer Contributions Sub-Account determined in accordance with
the vesting schedule specified in Section 22.5.

22.3 Minimum Employer Contribution

If the Plan is determined to be a top-heavy plan, the Employer Contributions
allocated to the Separate Account of each non-key employee who is an Eligible
Employee and who is employed by an Employer or a Related Company on the last day
of such top-heavy Plan Year shall be no less than the lesser of (i) three
percent of his compensation or (ii) the largest percentage of compensation that
is allocated as an Employer contribution and/or Tax-Deferred Contribution for
such Plan Year to the Separate Account of any key employee; except that, in the
event the Plan is part of a required aggregation group, and the Plan enables a
defined benefit plan included in such group to meet the requirements of Section
401(a)(4) or 410 of the Code, the minimum allocation of Employer Contributions
to each such non-key employee shall be three percent of the compensation. of
such non-key employee. Any minimum allocation to a non-key employee required by
this Section shall be made without regard to any

                                       71
<PAGE>   85

social security contribution made on behalf of the non-key employee, his number
of hours of service, his level of compensation, or whether he declined to make
elective or mandatory contributions. Notwithstanding the minimum top-heavy
allocation requirements of this Section, if the Plan is a top-heavy plan, each
non-key employee who is an Eligible Employee and who is employed by an Employer
or a Related Company on the last day of a top-heavy Plan Year and who is also
covered under any other top-heavy plan or plans of an Employer will receive the
top-heavy benefits provided under such other plan in lieu of the minimum
top-heavy allocation under the Plan.

22.4 Adjustments to Section 415 Limitations

If the Plan is determined to be a top-heavy plan and an Employer maintains a
defined benefit plan covering some or all of the Employees that are covered by
the Plan, the defined benefit plan fraction and the defined contribution plan
fraction, described in Article VII, shall be determined as provided in Section
415 of the Code by substituting "1.0" for "1.25" each place where "1.25"
appears, except that such substitutions shall not be applied to the Plan if (i)
the Plan is not a super top-heavy plan, (ii) the Employer Contribution for such
top-heavy Plan Year for each non-key employee who is to receive a minimum
top-heavy benefit hereunder is not less than four percent of such non-key
employee's compensation, and (iii) the minimum annual retirement benefit accrued
by a non-key employee who participates under one or more defined benefit plans
of an Employer or a Related Company for such top-heavy Plan Year is not less
than the lesser of three percent times years of service with an Employer or a
Related Company or thirty percent.

22.5 Accelerated Vesting

If the Plan is determined to be a top-heavy plan, a Participant's vested
interest in his Employer Contributions Sub-Account shall be determined no less
rapidly than in accordance with the following vesting schedule:
