purposes; or (iv) any leased employee, as such term is defined in Section 414(n)
of the Code.

2.1  Special Definitions

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

A "computation period" for purposes of determining an Employee's years of
Eligibility Service means (i) the 12-consecutive-month period beginning on the
first date he completes an Hour of Service, and (ii) each Plan Year beginning
after such date; provided, however, that if an employee first completed an Hour
of Service prior to the effective date of the Plan, a Plan Year shall not mean
any short Plan Year beginning on the effective date of the Plan, if any, but
shall mean any 12-consecutive-month period beginning after the first date the
employee completes an Hour of Service and before the effective date of the Plan
that would have been a Plan Year if the Plan had been in effect.

A "computation period" for purposes of determining an Employee's years of
Vesting Service means each Plan Year; provided, however, that if an employee
first completed an Hour of Service prior to the effective date of the Plan, a
Plan Year shall not mean any short Plan Year beginning on the effective date of
the Plan, if any, but shall mean any 12-consecutive-month period beginning
before the effective date of the Plan that would have been a Plan Year if the
Plan had been in effect.

The "continuous service" of an employee means the continuous service credited to
him in accordance with the provisions of this Article.

The "employment commencement date" of an employee means the date he first
completes an Hour of Service.

A "maternity/paternity absence" means a person's absence from employment with an
Employer or a Related Company because of the person's pregnancy, the birth of
the person's child, the placement of a child with the person in connection with
the person's adoption of the child, or the caring for the person's child
immediately following the child's birth or adoption.  A person's absence from
employment will not be considered a maternity/paternity absence unless the
person furnishes the Administrator such timely information as may reasonably be
required to establish that 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 "re-employment commencement date" of an employee means the first date
following a "severance date" on which he again completes an Hour of Service.

                                       8
<PAGE>

The "severance date" of an employee means the earlier of (i) the date on which
he retires, dies, or his employment with all Employers and Related Companies is
otherwise terminated, or (ii) the first anniversary of the first date of a
period during which he is absent from work with all Employers and Related
Companies for any other reason; provided, however, that if he terminates
employment with or is absent from work with all Employers and Related Companies
on account of service with the armed forces of the United States, he shall not
incur a "severance date" if he is eligible for re-employment rights under the
Uniformed Services Employment and Re-employment Rights Act of 1994 and he
returns to work with an Employer or a Related Company within the period during
which he retains such re-employment rights, but, if he does not return to work
within such period, his "severance date" shall be the earlier of the date which
is one year after his absence commenced or the last day of the period during
which he retains such re-employment rights.

2.2  Crediting of Hours of Service

A person shall be credited with an Hour of Service for:

(a)  each hour for which he is paid, or entitled to payment, for the performance
     of duties for an Employer, a Predecessor Employer, or a Related Company
     during the applicable "computation period"; provided, however, that hours
     compensated at a premium rate shall be treated as straight-time hours;

(b)  subject to the provisions of Section 2.4, each hour for which he is paid,
     or entitled to payment, by an Employer, a Predecessor Employer, or a
     Related Company on account of a period of time during which no duties are
     performed (irrespective of whether the employment relationship has
     terminated) due to vacation, holiday, illness, incapacity (including
     disability), lay-off, jury duty, military duty, or leave of absence;

(c)  each hour for which he would have been scheduled to work for an Employer, a
     Predecessor Employer, or a Related Company during the period that he is
     absent from work because of service with the armed forces of the United
     States provided he is eligible for re-employment rights under the Uniformed
     Services Employment and Re-Employment Rights Act of 1994 and returns to
     work with an Employer or a Related Company within the period during which
     he retains such re-employment rights;

(d)  each hour for which back pay, irrespective of mitigation of damages, is
     either awarded or agreed to by an Employer, a Predecessor Employer, or a
     Related Company; provided, however, that the same Hour of Service shall not
     be credited both under paragraph (a) or (b) or (c) of this Section, as the
     case may be, and under this paragraph (d); and provided, further, that the
     crediting of Hours of Service for back pay awarded or agreed to with
     respect to periods described in

                                       9
<PAGE>

     such paragraph (b) shall be subject to the limitations set forth therein
     and in Section 2.4;

(e)  solely for purposes of determining whether a person who is on a
     "maternity/paternity absence" has incurred a Break in Service for a
     "computation period", Hours of Service shall include those hours with which
     such person would otherwise have been credited but for such
     "maternity/paternity absence", or shall include eight Hours of Service for
     each day of "maternity/paternity absence" if the actual hours to be
     credited cannot be determined; except that not more than 501 hours are to
     be credited by reason of any "maternity/paternity absence"; provided,
     however, that any hours included as Hours of Service pursuant to this
     paragraph shall be credited to the "computation period" in which the
     absence from employment begins, if such person otherwise would incur a
     Break in Service in such "computation period", or, in any other case, to
     the immediately following "computation period"; and

(f)  solely for purposes of determining whether he has incurred a Break in
     Service, each hour for which he would have been scheduled to work for an
     Employer, a Predecessor Employer, or a Related Company during the period of
     time that he is absent from work on an approved leave of absence pursuant
     to the Family and Medical Leave Act of 1993; provided, however, that Hours
     of Service shall not be credited to an employee under this paragraph if the
     employee fails to return to employment with an Employer or Related Company
     following such leave.

Except as otherwise specifically provided with respect to Predecessor Employers,
Hours of Service shall not be credited for employment with a corporation or
business prior to the date such corporation or business becomes a Related
Company.

Notwithstanding any other provision of the Plan to the contrary, if an Employer
does not maintain records that accurately reflect actual hours of service, such
Employer shall credit Hours of Service to its employees in accordance with one
of the following equivalencies:

     employee shall be credited with 10 Hours of Service for each day on which
     he performs an Hour of Service.

(b)  If the Employer maintains its records on the basis of weeks worked, an
     employee shall be credited with 45 Hours of Service for each week in which
     he performs an Hour of Service.

(c)  If the Employer maintains its records on the basis of semi-monthly payroll
     periods, an employee shall be credited with 95 Hours of Service for each
     semi-monthly payroll period in which he performs an Hour of Service.

                                       10
<PAGE>

(d)  If the Employer maintains its records on the basis of months worked, an
     employee shall be credited with 190 Hours of Service for each month in
     which he performs an Hour of Service.

2.4  Limitations on Crediting of Hours of Service

In the application of the provisions of paragraph (b) of Section 2.2, the
following shall apply:

(a)  An hour for which a person is directly or indirectly paid, or entitled to
     payment, on account of a period during which no duties are performed shall
     not be credited to him if such payment is made or due under a plan
     maintained solely for the purpose of complying with applicable workers'
     compensation, unemployment compensation, or disability insurance laws.

(b)  Hours of Service shall not be credited with respect to a payment which
     solely reimburses a person for medical or medically-related expenses
     incurred by him.

(c)  A payment shall be deemed to be made by or due from an Employer, a
     Predecessor Employer, or a Related Company (i) regardless of whether such
     payment is made by or due from such employer directly or indirectly,
     through (among others) a trust fund or insurer to which any such employer
     contributes or pays premiums, and (ii) regardless of whether contributions
     made or due to such trust fund, insurer, or other entity are for the
     benefit of particular persons or are on behalf of a group of persons in the
     aggregate.

(d)  No more than 501 Hours of Service shall be credited to a person on account
     of any single continuous period during which he performs no duties (whether
     or not such period occurs in a single "computation period"), unless no
     duties are performed due to service with the armed forces of the United
     States for which the person retains re-employment rights as provided in
     paragraph (c) of Section 2.2.

2.5  Department of Labor Rules

The rules set forth in paragraphs (b) and (c) of Department of Labor Regulations
Section 2530.200b-2, which relate to determining Hours of Service attributable
to reasons other than the performance of duties and crediting Hours of Service
to "computation periods", are hereby incorporated into the Plan by reference.

2.6  Crediting of "Continuous Service"

A person shall be credited with "continuous service" for the aggregate of the
periods of time between his "employment commencement date" or any "re-employment
commencement date" and the "severance date" that next follows such "employment

                                       11
<PAGE>

commencement date" or "re-employment commencement date"; provided, however, that
an employee who has a "re-employment commencement date" within the 12-
consecutive-month period following the earlier of the first date of his absence
or his "severance date" (as defined in clause (i) of that definition) shall be
credited with "continuous service" for the period between his first date of
absence or "severance date" (as defined in clause (i) of that definition) and
"re-employment commencement date".

2.7  Eligibility Service

A full-time employee shall be credited with Eligibility Service equal to his

Service for each "computation period" during which he is credited with at least
1,000 Hours of Service.

If an employee terminates employment after becoming vested in Employer
Contributions hereunder, he shall be vested immediately in future Employer
Contributions made on his behalf upon his reparticipation in the Plan. If an
employee terminates employment without having been vested in Employer
Contributions hereunder, he shall be entitled to have his Vesting Service
rendered prior to his termination of employment restored and counted as Vesting
Service if he returns to service with an Employer before he has had five (5)
consecutive one-year Breaks In Service.  His entitlement to resume vesting in
Employer Contributions that were forfeited upon his initial termination of
service shall be determined in accordance with the provisions of Article XIV.

2.9  Crediting of Service on Transfer or Amendment

Notwithstanding any other provision of the Plan to the contrary, if any Employee
is transferred from employment covered under a qualified plan maintained by an
Employer or a Related Company for which service for vesting purposes is credited
based on elapsed time in accordance with Treasury Regulations Section 1.410(a)-7
to employment covered under the Plan or, any Employee who is not a full-time
employee is transferred from employment covered under a qualified plan
maintained by an Employer or a Related Company for which service for eligibility

credited with Eligibility Service and/or Vesting Service hereunder as provided
in Treasury Regulations Section 1.410(a)-7(f)(1).

3.1  Eligibility

With respect to eligibility to receive Wage Rate Contributions, each Employee
shall become an Eligible Employee as of the date he becomes an Employee.

With respect to eligibility to participate in all other aspects of the Plan,
each other Employee shall become an Eligible Employee as of the Enrollment Date
coinciding with or next following the date on which he has both attained age 18
and completed one of the following eligibility requirements:

(a)  one year of Eligibility Service; or

(b)  with respect to full-time employees as defined in Section 2.7, if earlier,
     90 days of Eligibility Service.

transfer date he has met the eligibility requirements of Section 3.1.
Otherwise, the eligibility of a person who is so transferred to participate in
the Plan shall be determined in accordance with Section 3.1.

3.3  Re-employment

The eligibility of a person to re-participate in the Plan who was neither vested
nor a participant at the time of his initial termination of employment with an
Employer and all Related Companies and who is re-employed by an Employer or a
Related Company shall be determined in accordance with Section 3.1 or 3.2.  If a
person who terminated employment with an Employer and all Related Companies is
re-employed as an Employee and if he had been an Eligible Employee and vested
prior to his termination of employment, he shall again become an Eligible
Employee on the date he is re-employed.  If a person who terminated employment
with an Employer and all Related Companies is re-employed as an Employee and if
he had been an Eligible Employee but had not yet vested prior to his termination
of employment, then he shall be readmitted as a Participant in the Plan in
accordance with Sections 3.1 or 3.2; provided however, that if his termination
of employment resulted in at least five (5) consecutive one-year Breaks in
Service, then he shall lose all prior eligibility service previously accrued

distribution to another qualified retirement plan (either via a direct rollover
or conventional rollover within 60 days).  The Administrator may require an
Employee to provide it with such information as it seems necessary or desirable

6.13 Exceptions to Allocation Requirements for Employer Contributions

Notwithstanding any other provision of the Plan to the contrary, the last day
allocation requirement described above shall not apply to any Participant who
would have otherwise been eligible to receive an allocation if he had not
terminated employment during the Contribution Period on or after his Normal
Retirement Date or he had not died or sustained a Disability during the
Contribution Period.

6.14 Vesting of Employer Contributions

A Participant's vested interest in his Qualified Nonelective and Qualified
Matching Contributions Sub-Accounts shall be at all times 100 percent.

With respect to an Employee who became a Participant in connection with the
merger of a plan into this Plan that provided 100 percent immediate vesting in
employer contributions prior to such merger, such Participant shall continue to
be 100 percent vested in the value of the Employer Contributions in his Account
under the Plan.

With respect to all other Participants, a Participant's vested interest in his
Regular and Additional Discretionary Matching Contributions, Discretionary
Profit-Sharing Contributions, Wage Rate Contributions and Prior Profit-Sharing
Contributions Sub-Accounts shall be zero percent until the Participant has
completed one year of Vesting Service at which time his vested interest in his
Matching Contributions Sub-Account shall be 100 percent.

Notwithstanding the foregoing, if a Participant is employed by an Employer or a
Related Company on his Normal Retirement Date, the date he becomes Disabled, or
the date he dies, his vested interest in his Regular and Additional
Discretionary Matching Contributions, Discretionary Profit-Sharing
Contributions, Wage Rate Contributions and Prior Profit-Sharing Contributions
Sub-Accounts shall be 100 percent.

As described in Article III, and notwithstanding any other provision of the Plan
to the contrary, a Participant's service credited for vesting purposes under a
Merged Plan as of the Merger Date, if any, shall be included as Vesting Service
under the Plan.

6.15 Election of Former Vesting Schedule

If the 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.

6.16 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 and that are applied against Employer
Contributions as provided in Article XIV.

                                  ARTICLE VII
                         LIMITATIONS ON CONTRIBUTIONS

7.1  Definitions

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

(a)  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 "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 "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 "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 "deferral percentage".  For purposes of determining
     the "aggregate limit", the "contribution percentages" and "deferral
     percentages" used shall be for the applicable "testing year".

(b)  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 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 "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 Code
     Sections 415(l)(2) and 419A(d)(2) allocated to his account for the
     "limitation year".

(c)  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.  To the extent permitted by regulations issued under Code
     Section 401(m), the Sponsor may elect to include the Tax-Deferred
     Contributions and/or Qualified Nonelective Contributions made to the Plan
     on an "eligible participant's" behalf for the Plan Year in computing the
     numerator of such "eligible participant's" "contribution percentage".
     Notwithstanding the foregoing, any Tax-Deferred Contributions, Qualified
     Matching Contributions, and/or Qualified Nonelective Contributions that are
     included in determining the numerator of an "eligible participant's"
     "deferral percentage" may not be included in determining the numerator of
     his "contribution percentage".

                                       24
<PAGE>

     Contributions made on an "eligible participant's" behalf for a Plan Year
     shall be included in determining his "contribution percentage" for such
     Plan Year only if the contributions are allocated to the "eligible
     participant's" Account as of a date within such Plan Year and are made to
     the Plan before the end of the 12-month period immediately following the
     Plan Year to which the contributions relate.  Contributions included for
     purposes of determining the "contribution percentage" for the "testing
     year" of an "eligible participant" who is not a Highly Compensated Employee
     relate to the "testing year" and therefore must be made before the last day
     of the Plan Year for which the limitation on Matching Contributions
     described in Section 7.7 is being determined.  The determination of an
     "eligible participant's" "contribution percentage" shall be made after any
     reduction required to satisfy the Code Section 415 limitations is made as
     provided in this Article VII and shall satisfy such other requirements as
     may be prescribed by the Secretary of the Treasury.

(d)  The "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.  To the extent permitted by regulations issued under Code Section
     401(k), the Sponsor may elect to include Qualified Matching Contributions
     and/or Qualified Nonelective Contributions made to the Plan on the Eligible
     Employee's behalf for the Plan Year in computing the numerator of such
     Eligible Employee's "deferral percentage".  Notwithstanding the foregoing,
     any Tax-Deferred Contributions, Qualified Matching Contributions, and/or
     Qualified Nonelective Contributions that are included in determining the
     numerator of an Eligible Employee's "contribution percentage" may not be
     included in determining the numerator of his "deferral percentage".

     Contributions made on an Eligible Employee's behalf for a Plan Year shall
     be included in determining his "deferral percentage" for such Plan Year
     only if they meet the following requirements:

     (1)  Tax-Deferred Contributions must relate to Compensation that either (i)
          would, but for the Eligible Employee's deferral election, have been
          received by the Eligible Employee during such Plan Year or (ii) is
          attributable to services performed by the Eligible Employee during
          such Plan Year and would, but for the Eligible Employee's deferral
          election, have been received by the Eligible Employee within two and
          one-half months after the close of the Plan Year.

     (2)  They must be allocated to the Eligible Employee's Account as of a date
          within such Plan Year.

     (3)  They must be made to the Plan before the end of the 12-month period
          immediately following the Plan Year to which they relate.

                                       25
<PAGE>

     Qualified Matching Contributions and Qualified Nonelective Contributions
     included for purposes of determining the "deferral percentage" of an
     Eligible Employee who is not a Highly Compensated Employee relate to the
     "testing year" and therefore must be made before the last day of the Plan
     Year for which the limitation on Tax-Deferred Contributions described in
     Section 7.4 is being determined.

     The determination of an Eligible Employee's "deferral percentage" shall be
     made after any reduction required to satisfy the Code Section 415
     limitations is made as provided in this Article VII and shall satisfy such
     other requirements as may be prescribed by the Secretary of the Treasury.

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

(f)  An "eligible participant" means any Eligible Employee who is eligible to
     have Tax-Deferred Contributions made on his behalf (if Tax-Deferred
     Contributions are taken into account in determining "contribution
     percentages"), or to participate in the allocation of Matching
     Contributions.

(g)  An "employee contribution" means any employee after-tax contribution
     allocated to an "eligible participant's" Account under any qualified plan
     of an Employer or a Related Company.

(h)  An "excess deferral" with respect to a Participant means that portion of a
     Participant's Tax-Deferred Contributions for his taxable year that, when
     added to amounts deferred for such taxable year under other plans or
     arrangements described in Code Section 401(k), 408(k), or 403(b) (other
     than any such plan or arrangement that is maintained by an Employer or
     Related Company), would exceed the dollar limit imposed under Code Section
     402(g) as in effect on January 1 of the calendar year in which such taxable
     year begins and is includible in the Participant's gross income under Code
     Section 402(g).

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

(j)  A "matching contribution" means any employer contribution allocated to an
     Eligible Employee's account under any plan of an Employer or a Related

                                       26
<PAGE>

     Company solely on account of "elective contributions" made on his behalf or
     "employee contributions" made by him.

(k)  A "qualified matching contribution" means any employer contribution
     allocated to an Eligible Employee's account under any plan of an Employer
     or a Related Company solely on account of "elective contributions" made on
     his behalf or "employee contributions" made by him that is a qualified
     matching contribution as defined in regulations issued under Code Section
     401(k), is nonforfeitable when made, and is distributable only as permitted
     in regulations issued under Code Section 401(k).

(l)  A "qualified nonelective contribution" means any employer contribution
     allocated to an Eligible Employee's account under any plan of an Employer
     or a Related Company that the Participant could not elect instead to
     receive in cash, that is a qualified nonelective contribution as defined in
     Code Sections 401(k) and 401(m) and regulations issued thereunder, is
     nonforfeitable when made, and is distributable only as permitted in
     regulations issued under Code Section 401(k).

(m)  The "test compensation" of an Eligible Employee or "eligible participant"
     for a Plan Year means compensation as defined in Code Section 414(s) and
     regulations issued thereunder, limited, however, to $150,000 (subject to
     adjustment annually as provided in Code Sections 401(a)(17)(B) and 415(d);
     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, if elected by the Sponsor, further limited solely to
     "test compensation" of an Employee attributable to periods of time when he
     is an Eligible Employee or "eligible participant".

(n)  The "testing year" means the Plan Year immediately preceding the Plan Year
     for which the limitations on "deferral percentages" and "contribution
     percentages" of Highly Compensated Employees are being determined.

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 dollar limit
imposed under Code Section 402(g), as in effect on January 1 of the calendar
year in which such taxable year begins.  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

                                       27
<PAGE>

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 account in determining the
                                   ---
Eligible Employee's "deferral percentage" for the "testing 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 as of the
last day of the month in which the distribution of Tax-Deferred Contributions
pursuant to this Section occurs.

7.3  Distribution of "Excess Deferrals"

Notwithstanding any other provision of the Plan to the contrary, if a
Participant notifies the Administrator in writing no later than the March 1
following the close of the Participant's taxable year that "excess deferrals"
have been made on his behalf under the Plan for such taxable year, the "excess
deferrals", plus any income and minus any losses attributable thereto, shall be
distributed to the Participant no later than the April 15 immediately following
such taxable year.  Any Tax-Deferred Contributions that are distributed to a
Participant who is a Highly Compensated Employee in accordance with this Section
shall nevertheless be taken into account in determining the Participant's
"deferral percentage" for the "testing year" in which the Tax-Deferred
Contributions were made.  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 as of the last day of the month in which the
distribution of Tax-Deferred Contributions pursuant to this Section occurs.

7.4  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
"deferral percentage" for such Eligible Employees that exceeds the greater of:

                                       28
<PAGE>

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

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

unless the "excess contributions", determined as provided in Section 7.5, are
distributed as provided in Section 7.6.

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 "deferral
percentages" of Highly Compensated Employees by reducing the percentage of their
deferral elections for any remaining portion of a Plan Year to such smaller
percentage 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 deferral
election to be effective the first day of the next following Plan Year.  In the
absence of such an election, the election 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.

In determining the "deferral percentage" for any Eligible Employee who is a
Highly Compensated Employee for the Plan Year, "elective contributions",
"qualified nonelective contributions", and "qualified matching contributions"
(to the extent that "qualified nonelective contributions" and "qualified
matching contributions" are taken into account in determining "deferral
percentages") made to his accounts under any plan of an Employer or a Related
Company that is not mandatorily disaggregated pursuant to IRS regulations
Section 1.410(b)- 7(c), as modified by Section 1.401(k)-1(g)(11), 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 Code Section 401(k) 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 Code Section 401(a)(4) or
410(b), then "deferral percentages" under the Plan shall be calculated as if the
Plan and such one or more other plans were a single plan.  Plans may be
aggregated to satisfy Code Section 401(k) only if they have the same plan year.

                                       29
<PAGE>

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 "qualified nonelective contributions" and/or "qualified matching
contributions" taken into account in determining "deferral percentages" for any
Plan Year.

Notwithstanding anything herein to the contrary, in the event that the
limitations of this Section are exceeded, the Administrator may take any and all
actions which, in its discretion are necessary or appropriate to ensure that the
limitations of this Section are satisfied, including, but not limited to using
"current year" testing in accordance with Code Section 401(k)(3)(A) and the
regulations thereunder.

7.5  Determination and Allocation of Excess Tax-Deferred Contributions Among
     Highly Compensated Employees

Notwithstanding any other provision of the Plan to the contrary, in the event
that the limitation on Tax-Deferred Contributions described in Section 7.4 is
exceeded in any Plan Year, the Administrator shall determine the dollar amount
of the excess by reducing the dollar amount of the contributions included in
determining the "deferral percentage" of Highly Compensated Employees in order
of their "deferral percentages" as follows:

(a)  The highest "deferral percentage(s)" shall be reduced to the greater of (1)
     the maximum "deferral percentage" that satisfies the limitation on Tax-
     Deferred Contributions described in Section 7.4 or (2) the next highest
     "deferral percentage".

(b)  If the limitation on Tax-Deferred Contributions described in Section 7.4
     would still be exceeded after application of the provisions of paragraph
     (a), the Administrator shall continue reducing "deferral percentages" of
     Highly Compensated Employees, continuing with the next highest "deferral
     percentage", in the manner provided in paragraph (a) until the limitation
     on Tax- Deferred Contributions described in Section 7.4 is satisfied.

The determination of the amount of "excess contributions" hereunder shall be
made after Tax- Deferred Contributions and "excess deferrals" have been
distributed pursuant to Sections 7.2 and 7.3, if applicable.

After determining the dollar amount of the "excess contributions" that have been
made to the Plan, the Administrator shall allocate such excess among Highly
Compensated Employees in order of the dollar amount of the Tax-Deferred,
Qualified Nonelective, and Qualified Matching Contributions (to the extent such
contributions are included in determining "deferral percentages") allocated to
their Accounts as follows:

(c)  The contributions made on behalf of the Highly Compensated Employee(s) with
     the largest dollar amount of Tax-Deferred and Qualified Matching
     Contributions

                                       30
<PAGE>

     allocated to his Account for the Plan Year shall be reduced by the dollar
     amount of the excess (with such dollar amount being allocated equally among
     all such Highly Compensated Employees), but not below the dollar amount of
     such contributions made on behalf of the Highly Compensated Employee(s)
     with the next highest dollar amount of such contributions allocated to his
     Account for the Plan Year.

(d)  If the excess has not been fully allocated after application of the
     provisions of paragraph (c), the Administrator shall continue reducing the
     permissible contributions made on behalf of Highly Compensated Employees,
     continuing with the Highly Compensated Employees with the largest remaining
     dollar amount of such contributions allocated to their Accounts for the
     Plan Year, in the manner provided in paragraph (c) until the entire excess
     determined above has been allocated.

7.6  Distribution of Excess Tax-Deferred Contributions

"Excess contributions" allocated to a Highly Compensated Employee pursuant to
the preceding Section, 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 such excess amounts are distributed
more than 21/2 months after the last day of the Plan Year for which the excess
occurred, an excise tax may be imposed under Code Section 4979 on the Employer
maintaining the Plan with respect to such amounts.

Excess amounts shall be distributed from the Highly Compensated Employee's Tax-
Deferred Contributions and Qualified Matching Contributions Sub-Accounts in
proportion to the Tax-Deferred Contributions and Qualified Matching
Contributions included in determining the Highly Compensated Employee's
"deferral percentage" for the Plan Year.

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 as of the
last day of the month in which the distribution of Tax-Deferred Contributions
pursuant to this Section occurs.

7.7  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" for the "testing year";
     or

                                       31
<PAGE>

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

unless the "excess contributions", determined as provided in Section 7.8, are
forfeited or distributed as provided in Section 7.9.

In determining the "contribution percentage" for any "eligible participant" who
is a Highly Compensated Employee for the Plan Year, "matching contributions",
"employee contributions", "qualified nonelective contributions", and "elective
contributions" (to the extent that "qualified nonelective contributions" and
"elective contributions" are taken into account in determining "contribution
percentages") made to his accounts under any plan of an Employer or a Related
Company that is not mandatorily disaggregated pursuant to IRS regulations
Section 1.410(b)- 7(c), as modified by IRS regulations Section 1.401(k)-
1(g)(11), 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 Code Section 401(m) 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 Code Section 401(a)(4) or
410(b), the "contribution percentages" under the Plan shall be calculated as if
the Plan and such one or more other plans were a single plan.  Plans may be
aggregated to satisfy Code Section 401(m) 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", "qualified nonelective contributions",
and/or "qualified matching contributions" taken into account in determining
"contribution percentages" for any Plan Year.

Notwithstanding anything herein to the contrary, in the event that the
limitations of this Section are exceeded, the Administrator may take any and all
actions which, in its discretion are necessary or appropriate to ensure that the
limitations of this Section are satisfied, including, but not limited to using
"current year" testing in accordance with Code Section 401(m)(2)(A) and the
regulations thereunder.

7.8  Determination and Allocation of Excess Matching Contributions Among Highly
     Compensated Employees

Notwithstanding any other provision of the Plan to the contrary, in the event
that the limitation on Matching Contributions described in Section 7.7 is
exceeded in any Plan Year, the Administrator shall determine the dollar amount
of the excess by reducing the dollar amount of the contributions included in
determining the "contribution percentage" of Highly Compensated Employees in
order of their "contribution percentages" as follows:

(a)  The highest "contribution percentage(s)" shall be reduced to the greater of
     (1) the maximum "contribution percentage" that satisfies the limitation on
     Matching Contributions described in Section 7.7 or (2) the next highest
     "contribution percentage".

(b)  If the limitation on Matching Contributions described in Section 7.7 would
     still be exceeded after application of the provisions of paragraph (a), the
     Administrator shall continue reducing "contribution percentages" of Highly
     Compensated Employees, with the next highest "contribution percentage", in
     the manner provided in paragraph (a) until the limitation of Matching
     Contributions described in Section 7.7 is satisfied.

The determination of the amount of excess Matching Contributions shall be made
after application of Sections 7.2, 7.3, and 7.6, if applicable.

After determining the dollar amount of the "excess contributions" that have been
made to the Plan, the Administrator shall allocate such excess among Highly
Compensated Employees in order of the dollar amount of the Matching and Tax-
Deferred Contributions (to the extent such contributions are included in
determining "contribution percentages") allocated to their Accounts as follows:

(c)  The contributions made on behalf of the Highly Compensated Employee(s) with
     the largest dollar amount of Matching and Tax-Deferred Contributions
     allocated to his Account for the Plan Year shall be reduced by the dollar
     amount of the excess (with such dollar amount being allocated equally among
     all such Highly Compensated Employees), but not below the dollar amount of
     such contributions made on behalf of the Highly Compensated Employee(s)
     with the next highest dollar amount of such contributions allocated to his
     Account for the Plan Year.

(d)  If the excess has not been fully allocated after application of the
     provisions of paragraph (c), the Administrator shall continue reducing the
     contributions made on behalf of Highly Compensated Employees, continuing
     with the Highly Compensated Employees with the largest remaining dollar
     amount of such contributions allocated to their Accounts for the Plan Year,
     in the manner

                                       33
<PAGE>

     provided in paragraph (c) until the entire excess determined above has been
     allocated.

7.9  Forfeiture or Distribution of "Excess Contributions"

"Excess contributions" allocated to a Highly Compensated Employee pursuant to
the preceding Section, 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 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 Code Section 4979 on the Employer maintaining the Plan with
respect to such amounts.

The distribution or forfeiture requirement of this Section shall be satisfied by
reducing contributions made by or on behalf of the Highly Compensated Employee
to the extent necessary in the following order:

(a)  Matching Contributions included in determining the Highly Compensated
     Employee's "contribution percentage" shall be distributed or forfeited, as
     appropriate.

(b)  Tax-Deferred Contributions included in determining the Highly Compensated
     Employee's "contribution percentage" shall be distributed.

Excess Matching Contributions shall be distributed only to the extent a
Participant has a vested interest in his Matching Contributions Sub-Account and
shall otherwise be forfeited.  Any amounts forfeited with respect to a
Participant pursuant to this Section shall be treated as a forfeiture under the
Plan as of the last day of the month in which the distribution of contributions
pursuant to this Section occurs.

7.10 Multiple Use Limitation

Notwithstanding any other provision of the Plan to the contrary, the following
multiple use limitation as required under Code Section 401(m) shall apply: the
sum of the average "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 "aggregate
limit". In the event that, after satisfaction of the limitations provided under
this Article, it is determined that contributions under the Plan fail to satisfy
the multiple use limitation contained herein, the multiple use limitation shall
be satisfied by further reducing the "deferral percentages" of Eligible
Employees who are Highly Compensated Employees to the extent necessary to
eliminate the excess, as provided in the preceding Sections. Instead of reducing
"deferral percentages", the Administrator may determine to satisfy the multiple
use limitation in an alternative manner, consistently applied, that may be
permitted by regulations issued under Code Section 401(m).

                                       34
<PAGE>

7.11 Treatment of Forfeited Matching Contributions

Any Matching Contributions that are forfeited pursuant to the provisions of the
preceding Sections of this Article shall be treated as a forfeiture under the
Plan and applied in accordance with the provisions of Article XIV.

7.12 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
Accounts.

7.13 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) $30,000 (adjusted as provided in Code Section
415(d)) or (ii) 25 percent of the Participant's compensation, as defined in Code
Section 415(c)(3) and regulations issued thereunder, for the "limitation year";
provided, however, that the limit in clause (i) shall be pro-rated for any short
"limitation year" as may be required under Code Section 415(c).  If the "annual
addition" to the 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 to the Participant's Account to the extent necessary
in the following order:

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

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

     Employer Contributions, other than Matching Contributions, otherwise
     allocable to the Participant's Account for the "limitation year", if any,
     shall be reduced.

The amount of any reduction of Tax-Deferred Contributions (plus any income
attributable thereto) shall be returned to the Participant.  The amount of any
reduction of Employer Contributions shall be deemed a forfeiture for the
"limitation year".

Amounts deemed to be forfeitures under this Section shall be held unallocated in
a suspense account established for the "limitation year" and shall be applied
against the Employer's contribution obligation for the next following
"limitation year" (and succeeding "limitation years", as necessary).  If a
suspense account is in existence at any

                                       35
<PAGE>

time during a "limitation year", all amounts in the suspense account must be
applied against the Employer's contribution obligation before any further
contributions that would constitute "annual additions" may be made to the Plan.
No suspense account established hereunder shall share in any increase or
decrease in the net worth of the Trust.

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 Code Section 415(c)(3) and regulations issued
thereunder), a reasonable error in determining the amount of "elective
contributions" that may be made with respect to any Participant under the limits
of Code Section 415, or other limited facts and circumstances that justify the
availability of the provisions set forth above.

7.14 Application of Code Section 415 Limitations Where Participant is Covered
     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 the preceding Section,
such excess shall be reduced first by returning "employee contributions" made by
the Participant to all defined contribution plans for the "limitation year", and
the income attributable thereto, to the extent necessary in the order prescribed
by the Administrator.  If the limitation contained in the preceding Section
still is not satisfied after all such "employee contributions" have been
returned, the excess shall be reduced by returning or forfeiting, as provided in
each defined contribution plan, "elective contributions" made on the
Participant's behalf to all such plans for the "limitation year", and, if
"elective contributions" are returned,  the income attributable thereto, to the
extent necessary in the order prescribed by the Administrator.  If the
limitation contained in the preceding Section still is not satisfied after all
such "elective contributions" have been returned or forfeited, the portion of
the employer contributions and of forfeitures for the "limitation year" under
all such plans that has been allocated to the Participant under such plans but
which exceeds the limitation set forth in the preceding Section, shall be deemed
a forfeiture for the "limitation year" and shall be disposed of as provided in
such plans; provided, however, that the amount of the employer contributions and
forfeitures that is a deemed forfeiture under this Section shall be effected in
the order prescribed by the Administrator, but first under any defined
contribution plan that is not a money purchase pension plan and, if the
limitation still is not satisfied, then under such money purchase pension plan.

7.15 Scope of Limitations

The Code Section 415 limitations contained in the preceding Sections shall be
applicable only with respect to benefits provided pursuant to defined
contribution plans and defined benefit plans described in Code Section 415(k).
For purposes of applying the Code

                                       36

Section 415 limitations contained in the preceding Sections, the term "Related
Company" shall be adjusted as provided in Code Section 415(h).

                           TRUST FUNDS AND ACCOUNTS

8.1  General Fund

The Trustee shall maintain a General Fund as required to hold and administer any
assets of the Trust that are not allocated among the Investment Funds as
provided in the Plan or the Trust Agreement. The General Fund shall be held and
administered as a separate common trust fund. The interest of each Participant
or Beneficiary under the Plan in the General Fund shall be an undivided
interest.

8.2  Investment Funds

The Sponsor shall determine the number and type of Investment Funds and shall
communicate the same and any changes therein in writing to the Administrator and
the Trustee. Each Investment Fund shall be held and administered as a separate
common trust fund. The interest of each Participant or Beneficiary under the
Plan in any Investment Fund shall be an undivided interest.

The Sponsor may determine to offer one or more Investment Funds that are
invested in whole or in part in equity securities issued by an Employer or a
Related Company that are "qualifying employer securities" as defined in ERISA
Section 407(d)(5). In no event may a Participant's Tax-Deferred Contributions
made for any Plan Year beginning on or after January 1, 1999 in excess of one
percent of the Participant's Compensation for such Plan Year be required to be
invested in such equity securities.

8.3  Loan Investment Fund

If a loan from the Plan to a Participant is approved in accordance with the
provisions of Article XII, the Sponsor shall direct the establishment and
maintenance of a loan Investment Fund in the Participant's name. The assets of
the loan Investment Fund shall be held and administered as a separate trust
fund.  A Participant's loan Investment Fund shall be invested in the note
reflecting the loan that is executed by the Participant in accordance with the
provisions of Article XII. Notwithstanding any other provision of the Plan to
the contrary, income received with respect to a Participant's loan Investment
Fund shall be allocated and the loan Investment Fund shall be administered as
provided in Article XII.

8.4  Income on Trust

Any dividends, interest, distributions, or other income received by the Trustee
with respect to any separate portion of the Trust maintained hereunder shall be
allocated by the Trustee to the portion of the Trust for which the income was
received.

8.5  Participant Accounts

                                       38
<PAGE>

As of the first date a contribution is made by or on behalf of an Employee there
shall be established an Account in his name reflecting his interest in the
Trust.  Each Account shall be maintained and administered for each Participant
and Beneficiary in accordance with the provisions of the Plan.  The balance of
each Account shall be the balance of the account after all credits and charges
thereto, for and as of such date, have been made as provided herein.

8.6  Sub-Accounts

A Participant's Account shall be divided into such separate, individual Sub-
Accounts as are necessary or appropriate to reflect the Participant's interest
in the Trust.

                    DEPOSIT AND INVESTMENT OF CONTRIBUTIONS

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 the contributions
made on his behalf 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.  If filed in accordance with any rules prescribed by the
Administrator, a Participant's change of investment election may be made
effective as of the date or dates prescribed by the Administrator.

10.2 Deposit of Contributions

All contributions made on a Participant's behalf 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 Account, 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 a
percentage, in the percentage increments prescribed by the Administrator, of the
amount eligible for transfer, which percentage may not exceed 100 percent.  Any
transfer election must be filed with the Administrator, in such form as the
Administrator shall prescribe.  Subject to any restrictions pertaining to a
particular Investment Fund, if filed in accordance with any rules prescribed by
the Administrator, a Participant's transfer election may be effective as of the
date or dates prescribed by the Administrator.

10.4 404(c) Protection

The Plan is intended to constitute a plan described in ERISA Section 404(c) and
regulations issued thereunder.  The fiduciaries of the Plan may be relieved of
liability for any losses that are the direct and necessary result of investment
instructions given by a Participant, his Beneficiary, or an alternate payee
under a qualified domestic relations order.

                        CREDITING AND VALUING ACCOUNTS

11.1 Crediting Accounts

All contributions made under the provisions of the Plan shall be credited to
Accounts in the Trust 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 has been completed for such
Valuation Date as provided in Section 11.2, as shall be determined by the
Administrator.

11.2 Valuing Accounts

Accounts in the Trust 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
the Administrator.

11.3 Plan Valuation Procedures

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

(a)  First, the value of the Trust 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 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 during the valuation
     period.

(c)  Finally, the net increase or decrease in the value of the Trust shall be
     allocated among Accounts in the Trust in the ratio of the balance of the
     portion of such Account in the Trust as of the preceding Valuation Date
     less any distributions, withdrawals, loans, and transfers from such Account
     balance in the Trust since the Valuation Date to the aggregate balances of
     the portions of all Accounts in the Trust similarly adjusted, and each
     Account in the Trust shall be credited or charged with the amount of its
     allocated share.

                                       42
<PAGE>

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
for contributions, loan payments, and transfers to and distributions,
withdrawals, loans, and transfers from such Trust 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 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 Account and Sub-Accounts as of a Valuation Date during the Plan Year.

                                       43

                                     LOANS

12.1 Application for Loan

A Participant who is a party in interest as defined in ERISA Section 3(14) may
make application to the Administrator for a loan from his Account.  Loans shall
be made to Participants in accordance with written guidelines which are hereby
incorporated into and made a part of the Plan.  A loan shall not be made
hereunder unless the Participant applying for the loan has incurred an immediate
and heavy financial need as defined in Article XIII.

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 loan; 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. 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 to the charging of
his Account for unpaid principal and interest amounts in the event the loan is
declared to be in default.  If a Participant's Account is subject to the
"automatic annuity" provisions under  Addendum A, the Participant's spouse must
consent in writing to any loan hereunder.  Any spousal consent given pursuant to
this Section must be made within the 90-day period ending on the date the Plan
acquires a security interest in the Participant's Account, must acknowledge the
effect of the loan, and must be witnessed by a Plan representative or a notary
public.  Such spousal consent shall be binding with respect to the consenting
spouse and any subsequent spouse with respect to the loan.  A new spousal
consent shall be required if the Participant's Account is used for security in
any renegotiation, extension, renewal, or other revision of the loan.

12.2 Reduction of Account Upon Distribution

Notwithstanding any other provision of the Plan, the amount of a Participant's
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 Account and the Participant's vested interest in his Account is payable to
more than one individual as Beneficiary, then the balance of the Participant's
vested interest in his Account shall be adjusted by reducing the vested account
balance by the

                                       44
<PAGE>

amount of the security used to repay the loan, as provided in the preceding
sentence, prior to determining the amount of the benefit payable to each such
individual.

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 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, except that the
     amortization schedule may be waived while a Participant is on a leave of
     absence from employment with an Employer or any Related Company for up to
     one year, provided that all of the following requirements are met:

     (i)  Such leave is either without pay or at a reduced rate of pay that,
          after withholding for employment and income taxes, is less than the
          amount required to be paid under the amortization schedule;

     (ii) Payments resume after the earlier of (a) the date such leave of
          absence ends or (b) the one-year anniversary of the date such leave
          began;

                                       45
<PAGE>

     (iii) The period during which payments are suspended does not exceed one
           year;

     (iv)  Payments resume in an amount not less than the amount required under
           the original amortization schedule; and

     (v)   The waiver of the amortization schedule does not extend the period of
           the loan beyond the maximum period permitted under this Article.

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 loan amount from the Investment Funds
in which it is invested, as directed by the Administrator, to the loan
Investment Fund established 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 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, unless payment is not made because the Participant is on a
leave of absence and the amortization schedule is waived as provided in Section
12.3(d), or there is an outstanding principal balance existing on a loan after
the last scheduled repayment date, the Administrator shall 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 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 Deemed Distribution Under Code Section 72(p)

If a Participant's loan is in default as provided in Section 12.5, the
Participant shall be deemed to have received a taxable distribution in the
amount of the outstanding loan balance as required under Code Section 72(p),
whether or not distribution may actually be made from the Plan without adversely
affecting the tax qualification of the Plan; provided, however, that the taxable
portion of such deemed distribution shall be reduced in accordance with the
provisions of Code Section 72(e) to the extent the deemed

                                       46
<PAGE>

distribution is attributable to the Participant's After-Tax Contributions. The
amount of any loan that is deemed to have been distributed to a Participant
hereunder shall cease to be an outstanding loan for purposes of Code Section
72(p) and a Participant shall not be treated as having received a taxable
distribution when his Account is offset by such outstanding loan balance as
provided in Section 12.5. Any interest that accrues on a loan after it is deemed
to have been distributed shall not be treated as an additional loan to the
Participant and shall not be included in the Participant's taxable income as a
deemed distribution. Notwithstanding the foregoing, however, unless a
Participant repays such loan, with interest, the amount of such loan, with
interest thereon calculated as provided in the original loan note, shall
continue to be considered an outstanding loan for purposes of determining the
maximum permissible amount of any subsequent loan under Section 12.3(b).

If a Participant elects to repay a loan after it is deemed to have been
distributed hereunder, such repayment shall be treated as an After-Tax
Contribution to the Plan solely for purposes of determining the taxable portion
of the Participant's Account and shall not be treated as an After-Tax
Contribution for any other Plan purpose, including application of the
limitations on contributions applicable under Code Sections 401(m) and 415.

12.7 Special Rules Applicable to Loans

Any loan made hereunder shall be subject to the following rules and any such
other rules as the Administrator may establish in accordance with any written
loan guidelines:

(a)  Minimum Loan Amount:  A Participant may not request a loan for less than
     $500.

(b)  Maximum Number of Outstanding Loans:  A Participant with an outstanding
     loan may not apply for another loan until the existing loan is paid in full
     and may not refinance an existing loan or attain a second loan for the
     purpose of paying off the existing loan.

     loan hereunder prior to the date it is due without penalty.

<PAGE>

(a)  The withdrawal is not in excess of the amount of the immediate and heavy

     Participant's Tax-Deferred Contributions and "elective contributions" for
     the taxable year of the withdrawal.

     of the Addendum, the Participant's spouse must consent to any withdrawal
     hereunder, unless the withdrawal is made in the form of a Qualified Joint

                                       50
<PAGE>

Distribution of a withdrawal amount shall be made from a Participant's Sub-
Accounts, to the extent necessary, in the order prescribed by the Administrator,
which order shall be uniform with respect to all Participants and non-

                                  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 the Employers and all Related Companies because of death, disability,
retirement, or other termination of employment.  Notice of a Participant's
Settlement Date shall be given by the Administrator to the Trustee.

14.2 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 Account upon the
     occurrence of his Settlement Date or his vested interest in his Account as
     of the date of distribution does not exceed $5,000 resulting in the
     distribution or deemed distribution to the Participant of his entire vested
     interest in his Account, the non-vested balance remaining in the
     Participant's Employer Contributions Sub-Account shall be immediately
     forfeited and his Account closed following (i) the Participant's Settlement
     Date, if the Participant has no vested interest in his Account and is
     therefore deemed to have received distribution on that date, or (ii) the
     date actual distribution is made to the Participant.

(b)  If the Participant's vested interest in his Account exceeds $5,000 and the
     Participant is eligible for and consents in writing to a single sum payment
     of his vested interest in his Account, the non-vested balance remaining in
     the Participant's Employer Contributions Sub-Account shall be immediately
     forfeited and his Account closed following his receipt of the single sum
     payment, provided that such distribution is made because of the
     Participant's Settlement Date. A distribution is deemed to be made because
     of a Participant's Settlement Date if it occurs prior to the end of the
     second Plan Year beginning on or after the Participant's Settlement Date.

14.3 Treatment of Forfeited Amounts

Whenever the non-vested balance of a Participant's Employer Contributions Sub-
Account is forfeited during a Plan Year in accordance with the provisions of the
preceding Section, the amount of such forfeiture, determined as of the last day
of the Plan Year in which the forfeiture occurs, shall be applied against Plan
expenses for such Plan Year or 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

                                       52
<PAGE>

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 be applied against Plan expenses and 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 paragraph (a) or
(b) of Section 14.2 and who is re-employed by an Employer or a Related Company
shall have such forfeited amounts recredited to a new Account in his name,
without adjustment for interim gains or losses experienced by the Trust, if he
returns to employment with an Employer or a Related Company before he incurs
five consecutive Breaks in Service commencing after the date he received, or is
deemed to have received, distribution of his vested interest in his Account.
Funds needed in any Plan Year to recredit the 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.

A former Participant who was a partially vested participant in a Merged Plan and
who received an actual distribution of his entire vested account and who returns
to employment within the time period described above may elect to repay to the
Plan the full amount of such distribution that is attributable to Employer
Contributions before the earlier of (i) the end of the five-year period
beginning on the date he is re-employed or (ii) the date he incurs five
consecutive Breaks in Service commencing after the date he received, or is
deemed to have received, distribution of his vested interest in his Account.

                                  ARTICLE XV
                                 DISTRIBUTIONS

15.1 Distributions to Participants

A Participant whose Settlement Date occurs shall receive distribution of his
vested interest in his 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.

15.2 Distributions to Beneficiaries

If a Participant dies prior to his Benefit Payment Date, his Beneficiary shall
receive distribution of the Participant's vested interest in his 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 Participant dies after the date distribution of his vested interest in his
Account begins under this Article, but before his entire vested interest in his
Account is distributed, his Beneficiary shall receive distribution of the
remainder of the Participant's vested interest in his 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 Account does not exceed $5,000,
distribution of such vested interest shall be made to the Participant in a
single sum payment as soon as reasonably practicable

                                       54
<PAGE>

following his Settlement Date. If a Participant has no vested interest in his
Account on his Settlement Date, he shall be deemed to have received distribution
of such vested interest as of his Settlement Date.

If a Participant's vested interest in his Account exceeds $5,000, distribution
shall not commence to such Participant prior to the date he attains age 62 (or
normal retirement age, if later) without the Participant's written consent and,
if the Participant is married and his Account is subject to the Qualified Joint
and Survivor Annuity requirements specified in Addendum A, the written consent
of his spouse.  Notwithstanding the foregoing, spousal consent shall not be
required if distribution is made through the purchase of a Qualified Joint and
Survivor Annuity or the spouse cannot be located or spousal consent cannot be
obtained for other reasons set forth in Code Section 401(a)(11) and regulations
issued thereunder.

If a Participant's Account is subject to the "automatic annuity" provisions of
Addendum A, the Participant's vested interest in his Account shall be deemed to
exceed $5,000 if the Participant's Benefit Payment Date has occurred with
respect to amounts currently held in his Account and as of such Benefit Payment
Date his vested interest in his Account exceeded $5,000.

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 Account shall commence to the Participant
no later than the earlier of:

(a)  unless the Participant elects a later date, 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)  his Required Beginning Date.

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

15.5 Re-Employment of a Participant

If a Participant whose Settlement Date has occurred is re-employed by an
Employer or a Related Company, his right to any distribution or further
distributions from the Trust arising from his prior Settlement Date shall be
suspended, 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.

                                       55

15.6 Restrictions on Alienation

Except as provided in Code Section 401(a)(13) (relating to qualified domestic
relations orders), Code Section 401(a)(13)(C) and (D) (relating to offsets
ordered or required under a criminal conviction involving the Plan, a civil
judgement in connection with a violation or alleged violation of fiduciary
responsibilities under ERISA, or a settlement agreement between the Participant
and the Department of Labor in connection with a violation or alleged violation
of fiduciary responsibilities under ERISA),  Section 1.401(a)-13(b)(2) of
Treasury regulations (relating to Federal tax levies and judgments), or as
otherwise required by law, 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 therefore 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 only upon receipt of written instructions to
such effect from the Administrator.  Any such payment shall be charged to the
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 a reasonable
period after the Administrator mails written notice of his eligibility to
receive a distribution hereunder to his last known address and makes such other
diligent effort to locate the person as the Administrator determines, 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

                                       56
<PAGE>

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 Code
Section 414(p), regardless of whether the Participant's Settlement Date has
occurred or whether the Participant is otherwise entitled to receive a
distribution under the Plan.

                                       57

                                FORM OF PAYMENT

16.1 Applicability

Subject to the provisions of Addenda A and B regarding grandfathered forms of
payment, the provisions of this Article shall apply to all Participants and
Beneficiaries eligible to receive a distribution under the Plan.

16.2 Normal Form of Payment

Distributions shall be made to the Participant, or, in the case of his death, to
his Beneficiary, in a single sum payment.

16.3 Optional Forms of Payment

The optional forms of payment described on Addenda A and B are available only
with respect to Merged Plan Accounts.

16.4 Change of Election

A Participant or Beneficiary who has elected an optional form of payment may
revoke or change his election at any time prior to his Benefit Payment Date by
filing his election with the Administrator in the form prescribed by the
Administrator.

16.5 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 a portion or all of any "eligible
rollover distribution" paid directly by the Plan to the "eligible retirement
plan" designated by the "qualified distributee".  Any such payment by the Plan
to another "eligible retirement plan" shall be a direct rollover.

Notwithstanding the foregoing, a "qualified distributee" may not elect a direct
rollover with respect to an "eligible rollover distribution" if the total value
of such distribution is less than $200 or with respect to a portion of an
"eligible rollover distribution" if the value of such portion is less than $500.
For purposes of this Section, the following terms have the following meanings:

(a)  An "eligible retirement plan" means an individual retirement account
     described in Code Section 408(a) an individual retirement annuity described
     in Code Section 408(b) an annuity plan described in Code Section 403(a), or
     a qualified trust described in Code Section 401(a) that accepts rollovers;
     provided, however, that,

                                       58
<PAGE>

     in the case of a direct rollover by a surviving spouse, an eligible
     retirement plan does not include a qualified trust described in Code
     Section 401(a).

(b)  An "eligible rollover distribution" means any distribution of all or any
     portion of the balance of a Participant's Account; provided, however, that
     an eligible rollover distribution does not include the following:

     (1)  any distribution to the extent such distribution is required under
          Code Section 401(a)(9).

     (2)  the portion of any distribution that consists of the Participant's
          After-Tax Contributions.

     (3)  any distribution that is one of a series of substantially equal
          periodic payment made not less frequently than annually for the life
          or life expectancy of the "qualified distributee" or the joint lives
          or life expectancies of the "qualified distributee" and the "qualified
          distributee's" designated beneficiary, or for a specified period of
          ten years or more.

     (4)  any hardship withdrawal of Tax-Deferred Contributions made in
          accordance with the provisions of Article XIII.

(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 Code Section 414(p).

16.6 Notice Regarding Forms of Payment

Within the 60 day period ending 30 days before a Participant's Benefit Payment
Date, the Administrator shall provide the Participant with a written explanation
of his right to defer distribution until Normal Retirement Age, his right to
make a direct rollover and the forms of payment  provided under the Plan.
Distribution of the Participant's Account may commence fewer 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 Normal
Retirement Age and his form of payment 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.

16.7 Re-Employment

If a Participant is re-employed by an Employer or a Related Company prior to
receiving distribution of the entire balance of his vested interest in his
Account, his prior election of a form of payment hereunder shall remain in
effect and distributions pursuant to such form shall continue uninterrupted.

                                       59
<PAGE>

16.8 Distribution in the Form of Employer Stock

Notwithstanding any other provision of the plan to the contrary, to the extent
any portion of a Participant's Account is invested in Employer Stock, he may
elect to receive a distribution of that portion in the form of Employer stock.

                                 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; provided, however, that such written spousal consent
shall not be required if the Participant is not married to such spouse on his
Benefit Payment Date.  A Participant's designation of a Beneficiary shall be
subject to the Qualified Preretirement Survivor Annuity provisions of the
Addendum A, with respect to Merged Plan Accounts, if applicable.

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.  In addition, the spouse's written consent must either (i)
specify any non-spouse Beneficiary designated by the Participant and that such
Beneficiary may not be changed without written spousal consent or (ii)
acknowledge that the spouse has the right to limit consent to a specific
Beneficiary, but permit 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.

The Sponsor shall appoint a Committee, consisting of at least three (3) persons
which shall be the Plan Administrator and named fiduciary of the Plan under
ERISA and to perform administrative duties as set forth herein.  Each member of
the Committee shall serve for such term as the Board of Directors of the Sponsor
may designate or until his death, resignation or removal by the Board.  The
Sponsor shall promptly appoint successors to fill vacancies in the Committee;
however, during interim periods which occur after resignation or death of a
Committee member and before the appointment of a new member, the Committee may
operate with fewer than three (3) members.  All usual and reasonable expenses of
the Committee may be paid in whole or in part by the Sponsor, and any expenses
not paid by the Sponsor shall be paid by the Trustee out of the principal or
income of the Trust.  The members of the Committee shall not receive
compensation with respect to their services for the Committee.  The members of
the Committee shall serve without bond or security for the performance of their
duties hereunder unless the applicable law makes the furnishing of such bond or
security mandatory or unless required by the Administrator.  The Sponsor may pay
the premium on any bond secured under this Section including the purchase of
fiduciary liability insurance for any person who becomes a fiduciary under this
Plan.

     o.  to delegate to one or more of the members of the Committee the right to
     act in its behalf in all matters connected with the administration of the
     Plan and Trust;

                                       63
<PAGE>

     p.  to delegate to any individual(s) such of the above powers and duties as
     the Committee deems appropriate;

Directors of the Sponsor will appoint a temporary substitute member to exercise
all the powers of the disqualified member concerning the matter in which he is
disqualified.

In addition to all other powers herein granted, and consistent with the
provisions hereof, the Committee shall have the discretionary authority to

this Plan shall be binding upon all of the Participants under this Plan, their
Beneficiaries and the Employers.

18.3 Claim Procedure

The Committee may prescribe procedures for obtaining benefits and is required to
provide a notice in writing to any person whose claim for benefits under this
Plan has been denied, setting forth (1) the specific reason for such denial, (2)
the specific reference to pertinent Plan provisions on which the denial is
based, (3) a description of any additional material or information necessary to
the claimant to perfect the claim and an explanation of why such material or
information is necessary, and (4) an explanation of the Plan's claim review
procedure as described below, including the name and address of the party to
whom an appeal should be sent.

                                       64
<PAGE>

A claimant has the right to appeal a denial of claim by written application to
the Committee within sixty (60) days of notice of denial or, if no such notice
has been given, at the end of the expiration of a reasonable period of time
after the claim was filed.  The claimant, or a duly authorized representative,
may review pertinent documents and may submit issues and comments in writing to
the Committee.

After the Committee reviews the claims appeal, a final decision shall be made
and communicated to the claimant within sixty (60) days of receipt of the appeal
by the Committee, unless special circumstances require an extension.  Such
extension cannot extend beyond one hundred twenty (120) days after receipt of
the appeal by the Committee.  The communication shall be set forth in writing in
a manner calculated to be understood by the claimant and shall identify the
reasons for the denial and shall reference any pertinent Plan provisions upon
which the denial is based.

18.4 Committee Procedures

The Committee shall adopt such bylaws as it deems desirable.  The Committee
shall elect one of its members as chairman and shall elect a secretary who may,
but need not be a member of the Committee.  The Committee shall advise the
Trustee of such elections in writing.  The Secretary of the Committee shall keep
a record of all meetings and forward all necessary communications to the
Trustee.

18.5 Authorization of Benefit Payments

The Committee shall issue directions to the Trustee concerning all benefits
which are to be paid from the Trust pursuant to the provisions of the Plan.  The
Committee shall keep on file, in such manner, as it may deem convenient or
proper, all reports from the Trustee.

18.6 Authority of the Sponsor

The Sponsor, by action of its board of directors, may:

(a)  allocate any of the powers, authority, or responsibilities for the
     operation and administration of the Plan (other than trustee
     responsibilities as defined in Section 405(c)(3) of ERISA) among named
     fiduciaries; and

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

except that no allocation by the Sponsor of, or designation by the Sponsor with
respect to, any of such powers, authority, or responsibilities to another named
fiduciary or a person other than a named fiduciary shall become effective unless
such allocation or designation shall first be accepted by such named fiduciary
or other person in a writing signed by it and delivered to the Sponsor.

                                       65
<PAGE>

18.7  Qualified Domestic Relations Orders

The Administrator 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.

18.8  Indemnity

The Sponsor indemnifies and saves harmless any member of the Board of Directors
of an Employer or of the Sponsor, any member of the Committee and any Employee
of an Employer or of the Sponsor from and against any and all loss resulting
from liability to which any such person may be subjected by reason of any
conduct (except willful or reckless misconduct) in a fiduciary capacity under
this Plan or Trust, or both, including all expenses reasonably incurred in such
person's defense, in case the Corporation fails to provide such defense.  The
indemnification provisions of this Section shall not relieve any such person of
any liability he may have under ERISA for breach of a fiduciary duty.

                                  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.  The Sponsor shall make no
retroactive amendment to the Plan unless such amendment satisfies the
requirements of Code Section 401(b) and/or Section 1.401(a)(4)-11(g) of the
Treasury regulations, as applicable.

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
     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.

(b)  All 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

                                       67
<PAGE>

     defined contribution plan (other than an employee stock ownership plan as
     defined in Code Section 4975(e)(7)), the Participant's written consent to
     the commencement of distribution shall not be required regardless of the
     value of the vested portions of his 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 Code Section 401(a)(9)) 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 Code Section 4975(e)(7), a tax credit employee stock ownership plan as
     defined in Code Section 409, or a simplified employee pension as defined in
     Code Section 408(k)) 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 Code Section 402(e)(4), 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 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
from 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 Code Section 401(a)(9)), 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"

                                       68
<PAGE>

as defined in Code Section 402(e)(4), 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 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 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 ENTITIES

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.

                                       70

                                  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 as a general
charge thereon, unless the Sponsor elects to make payment. Notwithstanding the
foregoing, the Sponsor may direct that administrative expenses that are
allocable to the Account of a specific Participant shall be paid from that
Account and that the costs incident to the management of the assets of an
Investment Fund or to the purchase or sale of securities held in an Investment
Fund shall be paid by the Trustee from such Investment Fund.

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

21.7 Withholding

                                       71
<PAGE>

The Trustee shall withhold any tax which by any present or future law 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 or XXII 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 Participant under the provisions of Article VI
or XXII as in effect during each such Plan Year.  The amounts of such additional
contributions shall be credited to the Account of such Participant.  Any
additional contributions made pursuant to this Section shall be made in
accordance with, and subject to the limitations of the applicable provisions of
the Plan.

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 Code Section 401(a), the exempt status
of the Trust under Code Section 501(a), and the deductibility of the
contribution under Code Section 404.  Except as otherwise provided in this
Section and Section 21.11, however, in no event

                                       72
<PAGE>

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 Code Section404,

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 Code Section 401(a), 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 ERISA Section
403(c)(2)(B).

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 state or commonwealth in which
the Sponsor has its principal place of business, except as preempted by
applicable Federal law.  The invalidity or illegality of any provision of the
Plan shall not affect the 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

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

                                       73
<PAGE>

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. 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.

21.16  Merged Plans

In the event another defined contribution plan (the "merged plan") is merged
into and made a part of the Plan, each Employee who was eligible to participate
in the "merged plan" immediately prior to the merger shall become an Eligible
Employee on the date of the merger.  In no event shall a Participant's vested
interest in his Sub-Account attributable to amounts transferred to the Plan from
the "merged plan" (his "transferee Sub-Account") on and after the merger be less
than his vested interest in his account under the "merged plan" immediately
prior to the merger.  Notwithstanding any other provision of the Plan to the
contrary, a Participant's service credited for eligibility and vesting purposes
under the "merged plan" as of the merger, if any, shall be included as
Eligibility and Vesting Service under the Plan to the extent Eligibility and
Vesting Service are credited under the Plan.  Special provisions applicable to a
Participant's "transferee Sub-Account", if any, shall be specifically reflected
in the Plan or in an Addendum to the Plan.

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.

21.18  Veterans Re-Employment Rights

Notwithstanding any other provision of the Plan to the contrary, contributions,
benefits, and service credit with respect to qualified military service shall be
provided in accordance with Code Section 414(u). The Administrator shall notify
the Trustee of any Participant with respect to whom additional contributions are
made because of qualified military service.

22.1 Definitions

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

(a)  The "compensation" of an employee means "compensation" as defined in Code
     Section 415 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 $170,000 (subject to adjustment annually as provided
     in Code Sections 401(a)(17)(B) and 415(d); 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).

(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 Code Section 416(i)(1) 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 Code Sections 401(a)(4) and 410.

(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 Code
     Section 401(a)(4) or Code Section 410, 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

                                       75
<PAGE>

     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 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 Code Section 416(g) 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 Code Section 416(g)  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 for employees (other than "key
     employees") 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 Code
     Section 411(b)(1)(C)  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

                                       76
<PAGE>

     plan is included in a "required" 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 this
Article shall continue to apply.

22.3 Minimum Employer Contribution

If the Plan is determined to be a "top-heavy plan" for a Plan Year, the Employer
Contributions, other than Matching Contributions, allocated to the 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 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 Code Section 401(a)(4) or 410, 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 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.

Employer Contributions allocated to a Participant's Account in accordance with
this Section shall be considered annual additions under Article VII for the
limitation year for which they are made and shall be separately accounted for.
Employer Contributions allocated to a Participant's Account shall be allocated
upon receipt among the Investment Funds in accordance with the Participant's
currently effective investment election.

22.4 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:

in one of the following plans that merged into the Plan effective April 1, 2000:

1.   Advent Electric Co., Inc. 401(k) Profit Sharing Plan;
2.   American Air Company, Inc. 401(k) Profit Sharing Plan;
3.   Building One Services Corporation 401(k) Profit Sharing Plan;

11.  Walker Engineering, Inc. Employee Savings Plan & Trust Agreement
     (restricted to those participants in the plan on June 30, 1988)

The term "Participant" when used in this Addendum refers only to a Participant
who satisfies the requirements described above.

A.2  Definitions

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

(a)  The "automatic annuity form" means the form of annuity that will be
     purchased on behalf of a Participant who has elected to receive
     distribution through the purchase of an annuity contract that provides for
     payment over his life unless the Participant elects another form of
     annuity.

(b)  A "qualified election" means an election that is made during the qualified
     election period. A "qualified election" of a form of payment other than a
     Qualified Joint and Survivor Annuity or designating a Beneficiary other
     than the Participant's spouse to receive amounts otherwise payable as a
     Qualified Preretirement Survivor Annuity must include the written consent
     of the Participant's spouse, if any.  A Participant's spouse will be deemed
     to have given written consent to the Participant's election if the
     Participant establishes to the satisfaction of a Plan representative that
     spousal consent cannot be obtained because the spouse cannot be located or
     because of other circumstances set forth in Code Section 401(a)(11) and
     regulations issued thereunder.  The spouse's written consent must
     acknowledge the effect of the Participant's election and must be witnessed
     by a Plan representative or a notary public. In addition, the spouse's
     written consent

                                       80
<PAGE>

     must either (i) specify the form of payment selected instead of a Qualified
     Joint and Survivor Annuity, if applicable, and that such form may not be
     changed (except to a Qualified Joint and Survivor Annuity) without written
     spousal consent and specify any non-spouse Beneficiary designated by the
     Participant, if applicable, and that such Beneficiary may not be changed
     without written spousal consent or (ii) acknowledge that the spouse has the
     right to limit consent as provided in clause (i), but permit the
     Participant to change the form of payment selected or the designated
     Beneficiary without the spouse's further consent. Any written consent given
     or deemed to have been given by a Participant's spouse hereunder shall be
     irrevocable and shall be effective only with respect to such spouse and not
     with respect to any subsequent spouse.

(c)  The "qualified election period" with respect to the "automatic annuity
     form" means the 90 day period ending on a Participant's Benefit Payment
     Date. The "qualified election period" with respect to a Qualified
     Preretirement Survivor Annuity means the period beginning on the later of
     (i) the date his Account becomes subject to the automatic annuity
     provisions of this Addendum or (ii) the first day of the Plan Year in which
     the Participant attains age 35 or, if he terminates employment prior to
     such date, the day he terminates employment with his Employer and all
     Related Companies. A Participant whose employment has not terminated may
     make a "qualified election" designating a Beneficiary other than his spouse
     prior to the Plan Year in which he attains age 35; provided, however, that
     such election shall cease to be effective as of the first day of the Plan
     Year in which the Participant attains age 35.

A.3  Normal Form of Payment

Unless a Participant, or his Beneficiary (if the Participant has died), elects
the optional annuity form of payment provided in this Addendum or the optional
form described in Section XVI, distribution shall be made to the Participant, or
his Beneficiary, as the case may be, in the normal form of payment provided in
Article XVI.

A.4  Optional Annuity Form of Payment

The Participant (or his Beneficiary, if the Participant has died) may elect to
receive distribution of all or a portion of his Account through the purchase of
a single premium, nontransferable annuity contract from an insurance company.
The Participant or his Beneficiary may select, subject to the automatic annuity
form requirements of Section A.6, the term and the form of the annuity payment
from those available from the insurance company.  Notwithstanding the foregoing,
a Participant's Beneficiary may not elect to receive distribution of an annuity
payable over the joint lives of the Beneficiary and any other individual.

The terms of any annuity contract purchased hereunder and distributed to a
Participant or his Beneficiary shall comply with the requirements of the Plan.

                                       81
<PAGE>

A.5  Change of Election

Subject to the automatic annuity requirements of this Addendum, a Participant or
Beneficiary who has elected a form of payment provided under Article XVI or this
Addendum may revoke or change his election at any time prior to his Benefit
Payment Date by filing his election with the Administrator in the form
prescribed by the Administrator.

A.6  Automatic Annuity Requirements

If a Participant elects to receive distribution through the purchase of an
annuity contract that provides for payment over his life, distribution shall be
made to such Participant through the purchase of an annuity contract that
provides for payment in one of the following "automatic annuity forms", unless
the Participant elects a different type of annuity.

(a)  The "automatic annuity form" for a Participant who is married on his
     Benefit Payment Date is the 50 percent Qualified Joint and Survivor
     Annuity.

(b)  The "automatic annuity form" for a Participant who is not married on his
     Benefit Payment Date is the Single Life Annuity.

A Participant who has elected to receive distribution through the purchase of an
annuity contract that provides for payment over his life may only change his
election of a form of payment pursuant to a "qualified election"; provided,
however, that spousal consent shall not be required if the form of payment
elected by the Participant is a Qualified Joint and Survivor Annuity.

A.7  Qualified Preretirement Survivor Annuity Requirements

If a married Participant who elects to receive distribution through the purchase
of an annuity contract that provides for payment over his life dies before his
Benefit Payment Date, his spouse shall receive distribution of the value of the
Participant's vested interest in his Account through the purchase of an annuity
contract that provides for payment over the life of the Participant's spouse.  A
Participant's spouse may elect to receive distribution under any one of the
other forms of payment available under the Plan instead of in the Qualified
Preretirement Survivor Annuity form.  A married Participant who has elected to
receive distribution through the purchase of annuity contract that provides for
payment over his life may only designate a non-spouse Beneficiary to receive
distribution of his Account pursuant to a "qualified election".

A.8  Notice Regarding Forms of Payment

                                       82
<PAGE>

The explanation provided to a Participant pursuant to Article XVI, shall include
a description of the annuity form of payment available under this Addendum,
including a written explanation of (i) the terms and conditions of the
"automatic annuity form" applicable if the Participant elects to receive
distribution through the purchase of an annuity that provides for payment over
his life, (ii) the Participant's right to choose a form of payment other than
the "automatic annuity form" or to revoke such choice, and (iii) the rights of
the Participant's spouse.

The Administrator shall provide such explanation within the 60 day period ending
30 days before the Participant's Benefit Payment Date. Notwithstanding the
foregoing, distribution of the Participant's Account may commence fewer than 30
days after such explanation 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 Normal Retirement Age and his election of a form of
payment for a period of at least 30 days following his receipt of the
explanation, (ii) the Participant, after receiving the explanation,
affirmatively elects an early distribution with his spouse's written consent, if
necessary, and, if the Participant has elected distribution through the purchase
of an annuity contract that provides for payment over his life, (iii) the
Participant may revoke his election at any time prior to the later of his
Benefit Payment Date or the expiration of the seven-day period beginning the day
after the date the explanation is provided to him, and (iv) distribution does
not commence to the Participant before such revocation period ends.

In addition, the Administrator shall provide a Participant who has elected
distribution through the purchase of an annuity that provides for payment over
his life with a written explanation of (i) the terms and conditions of the
Qualified Preretirement Survivor Annuity, (ii) the Participant's right to
designate a non-spouse Beneficiary to receive distribution of his Account
otherwise payable as a Qualified Preretirement Survivor Annuity or to revoke
such designation, and (iii) the rights of the Participant's spouse.  The
Administrator shall provide such explanation within one of the following
periods, whichever ends last:

(a)  the period beginning with the first day of the Plan Year in which the
     Participant attains age 32 and ending on the last day of the Plan Year
     preceding the Plan Year in which the Participant attains age 35;

(b)  the period beginning 12 calendar months before the date an individual
     becomes a Participant and ending 12 calendar months after such date; or

(c)  provided the Participant's Account does not include assets transferred
     directly from a plan subject to Code Section 417, the period beginning 12
     calendar months before the date the Participant elects to receive
     distribution through the purchase of an annuity contract that provides for
     payment over his life and ending 12 calendar months after such date;
     provided, however, that in the case of a Participant who separates from
     service prior to attaining age 35, the explanation

                                       83
<PAGE>

     shall be provided to such Participant within the period beginning 12
     calendar months before the Participant's separation from service and ending
     12 calendar months after his separation from service.


A.9  Re-Employment

If a Participant had elected to receive distribution through the purchase of an
annuity contract that provides for payment over his life, and he returned to
employment causing the suspension of payment of his benefit, the automatic
annuity and Qualified Preretirement Survivor Annuity requirements described in
this Addendum shall continue to apply to his entire Merged Plan Account upon
subsequent termination.
