                 1.8 of the Basic Plan Document #04.

                 If the Employer chooses an non-integrated allocation formula,

6.       EMPLOYER CONTRIBUTIONS
         NOTE:  The integrated allocation formulas below are for Plan Years
         beginning in 1989 and later.  The Employer's allocation for earlier
         years shall be as specified in its Plan prior to Amendment for the Tax
         Reform Act of 1986.

         Employer Contributions will be allocated in accordance with the method
         selected below.  If in Section 9 herein, the Employer elects to
         allocate forfeitures, they will be treated as additional Employer
         Contributions and allocated accordingly.

         [ ]     (a)      Non-Integrated Contribution and Allocation Formula
                          (See Minimum Contributions under Top-Heavy Plans at
                          Section 7). 

                          The Employer shall contribute and allocate to the
                          account of each eligible Participant ______% (not
                          more than 25%) of such Participant's Compensation
                          plus any forfeitures (only if they are reallocated to
                          Participants under Section 9), in such Plan Year.

         [ ]     (b)      Integrated Contribution and Allocation Formula (See
                          Minimum Contributions under Top-Heavy Plans at
                          Section 7). 

                          The Employer shall contribute _____% of each
                          Participant's Compensation for the Plan Year.
                          Contributions plus any forfeitures (only if they are
                          reallocated to Participants under Section 9) will be
                          allocated to each Participant's account as follows:

                          (i)     First, to the extent contributions and
                                  forfeitures are sufficient, all Participants
                                  will receive an allocation equal to 3% of
                                  their Compensation.

                         (ii)     Next, any remaining Employer Contributions
                                  and forfeitures will be allocated to
                                  Participants who have Compensation in excess
                                  of the Taxable Wage Base (excess
                                  Compensation).  Each such Participant will
                                  receive an allocation in the ratio that his
                                  or her excess compensation bears to the
                                  excess Compensation of all Participants.
                                  Participants may only receive an allocation
                                  of 3% of excess Compensation.

                       (iii)      Next, any remaining Employer contributions
                                  and forfeitures will be allocated to all
                                  Participants in 
<PAGE>   7

                          the ratio that their Compensation plus excess
                          Compensation bears to the total Compensation plus
                          excess Compensation of all Participants. Participants
                          may only receive an allocation of up to 2.7% of their
                          Compensation plus excess Compensation, under this
                          allocation method.  If the Taxable Wage Base is
                          defined at Section 3(h) above is less than the        
                          maximum, but more than the greater of $10,000 or 20%
                          of the maximum, then the 2.7% must be reduced. If the
                          amount specified is greater than 80% but less than
                          100% of the maximum Taxable Wage Base, the 2.7% must
                          be reduced to 2.4%.  If the amount specified is
                          greater than the greater of $10,000 or 20% of the
                          maximum Taxable Wage Base, but not more than 80%,
                          2.7% must be reduced to 1.3%.

                 NOTE:  If the Plan is not Top-Heavy, subparagraphs (i) and
                 (ii) above may be disregarded and 5.7%, 5.4% or 4.3% may be
                 substituted for 2.7%, 2.4% or 1.3% where it appears in (iii)
                 above.

                 (iv)     Next, any remaining Employer contributions and
                          forfeitures will be allocated to all Participants
                          (whether or not they received an allocation under the
                          preceding paragraphs) in the ratio that each
                          Participant's Compensation bears to all Participants'
                          Compensation.

         [ ]     (c)  Alternative Integrated Allocation Formula (See
                      Minimum Contributions Under Top-Heavy Plans at
                      Section 7) 

                      The Employer shall contribute and allocate to the account
                      of each eligible Participant 3% of each eligible
                      Participant's Compensation (not in excess of the Taxable
                      Wage Base defined at Section 3(h) hereof) plus 5% of
                      Compensation in excess of the Taxable Wage Base defined
                      at Section 3(h) hereof.  The percentage on excess
                      compensation may  not exceed the lesser of (i) the amount
                      first specified in this paragraph or (ii) the
                      greater of 5.7% or the percentage rate of tax under Code
                      Section 3111(a) as in effect on the first day of the Plan
                      Year attributable to the Old Age (OA) portion of the
                      OASDI provisions of the Social Security Act.  If this
                      allocation formula is used for Top-Heavy Plans, the first
                      blank may not be less than 3%.  If the Employer specifies
                      a Taxable Wage Base in Section 3(h) which is lower than
                      the Taxable Wage Base for Social Security purposes
                      (SSTWB) in effect as of the first day of the Plan Year,
                      the percentage contributed with respect to excess
                      Compensation must be adjusted. If the Plan's Taxable
                      Wage Base is greater than the larger of $10,000 or 20% of
                      the SSTWB but not more than 80% of the SSTWB, the excess
                      percentage is 4.3%.  If the Plan's Taxable Wage Base is
                      greater than 80% of the SSTWB but less than 100% of the
                      SSTWB, the excess percentage is 5.4%.

                          If forfeitures are reallocated pursuant to Section 9,
                          they will be allocated pro-rata based on the
                          Participant's Compensation as a percentage of the
                          Compensation of all Participants.

         NOTE:  Only one plan maintained by the Employer may be integrated with
         Social Security.

         (d)     Allocation of Excess Amounts (Annual Additions)
                 In the event that the allocation formula above results in an
                 Excess Amount, such excess shall be:

                 [X]       (i)    placed in a suspense account accruing no
                                  gains or losses for the benefit of the
                                  Participant. 
                 [ ]      (ii)    reallocated as additional Employer
                                  contributions to all other Participants to
                                  the extent that they do not have an Excess
                                  Amount.

                 If no answer is specified, the suspense account method will be
                 used.

7.       MINIMUM CONTRIBUTIONS UNDER TOP-HEAVY PLANS
         Notwithstanding any other provision herein, the Employer shall make a
         minimum contribution for each eligible Participant with respect to any
         Plan Year for which the Plan is Top-Heavy.  The minimum contribution
         shall be determined in accordance with paragraph 14.2 of Basic Plan
         Document #04 for:
         [ ]     (a)      all eligible Participants.

                          requirements of Code Section 401(a)(26) and 410(b).
                          (The requirements are effective for 1989 and
                          subsequent Plan Years.)
         [X]     (b)      The Employer will allocate Employer related
                          contributions to Employees who terminate during the

                                           provided that the Participant has
                                           completed a Year of Service as
                                           defined for Allocation Accrual
                                           purposes.
                          [ ]      (v)     Other termination of employment even
                                           though the Participant has not
                                           completed a Year of Service.

         policy.
                 [ ]       (i)    Forfeitures shall be reallocated at the end
                                  of the Plan Year during which the former

                                  consecutive one year Break in Service.
                 [X]      (ii)    Forfeitures will be reallocated immediately

10.      LIMITATIONS ON ALLOCATIONS
         [ ]     This is the only Plan the Employer maintains or ever
                 maintained, therefore, this section is not applicable.
         [X]     The Employer does maintain or has maintained another Plan
                 (including a Welfare Benefit Fund or an individual medical
                 account [as defined in Code Section 415(1)(2)], under which
                 amounts are treated as Annual Additions) and has completed the
                 proper sections below.
         Complete (a), (b) and (c) only if you maintain or ever maintained
         another qualified plan including a Welfare Benefit Fund or an
         individual medical account [as defined in Code Section 415(1)(2)], in
         which any Participant in this Plan is (or was) a participant or could
         possibly become a participant.
         (a)     If the Participant is covered under another qualified Defined
                 Contribution Plan maintained by the Employer, other than a
                 Master or Prototype Plan:
                 [X]       (i)    The provisions of Article X of the Basic Plan
                                  Document #04 will apply, as if the other plan
                                  were a Master or Prototype Plan.
                 [ ]      (ii)    Attach provisions stating the method under
                                  which the plans will limit total Annual
                                  Additions to the Maximum Permissible Amount,
                                  and will properly reduce any Excess Amounts,
                                  in a manner that precludes Employer
                                  discretion.
         (b)     If a Participant is or ever has been a participant in a
                 Defined Benefit Plan maintained by the Employer: Attach
                 provisions which will satisfy the 1.0 limitation of Code
                 Section 415(e).  Such language must preclude Employer

                 discretion.  The Employer must also specify the interest and
                 mortality assumptions used in determining Present Value in the
                 Defined Benefit Plan.
         (c)     The minimum contribution or benefit required under Code
                 Section 416 relating to Top-Heavy Plans shall be satisfied by:
                 [X]       (i)    this Plan.
                 [ ]      (ii)    ____________________________________________
                                  ____________________________________________
                                  (Name of other qualified plan of the
                                   Employer.)
                 [ ]     (iii)    Attach provisions stating the method under
                                  which the minimum contribution and benefit
                                  provisions of Code Section 416 will be
                                  satisfied.  If a Defined Benefit Plan is or
                                  was maintained, an attachment must be
                                  provided showing interest and mortality
                                  assumptions used in determining the Top-Heavy
                                  Ratio.

11.      VESTING
         Each Participant shall acquire a vested and nonforfeitable percentage
         in his or her account balance attributable to Employer contributions
         and the earnings thereon under the procedures selected below except
         with respect to any Plan Year during which the Plan is Top-Heavy, in
         which case the Two-twenty vesting schedule [Option (b)(iv)] shall
         automatically apply unless the Employer has already elected a faster
         vesting schedule. If the Plan is switched to option (b)(iv), because
         of its Top-Heavy status, that vesting schedule will remain in effect
         even if the Plan later becomes non-Top-Heavy until the Employer
         executes an amendment of this Adoption Agreement indicating otherwise.

         (a)     Computation Period:
                 The computation period for purposes of determining Years of
                 Service and Breaks in Service for purposes of computing a
                 Participant's nonforfeitable right to his or her account
                 balance derived from Employer contributions: [ ]       (i)
                 shall not be applicable since Participants are always fully
                 vested,
                 [ ]      (ii)    shall commence on the date on which an
                                  Employee first performs an Hour of Service
                                  for the Employer and each subsequent
                                  12-consecutive month period shall commence on
                                  the anniversary thereof, or
                 [X]     (iii)    shall commence on the first day o the Plan
                                  Year during which an Employee first performs
                                  an Hour of Service for the Employer and each
                                  subsequent 12-consecutive month period shall
                                  commence on the anniversary thereof.

         A Participant shall receive credit for a Year of Service if he or she
         completes at least 1,000 Hours of Service [or if lesser, the number of
         hours specified at 3(j)(iii) of this Adoption Agreement] at any time
         during the 12-consecutive month computation period. Consequently a Year
         of Service may be earned prior to the end of the 12-consecutive month
         period and the Participant need not be employed at the end of the
         12-consecutive month computation period to receive credit for a Year of
         Service.

         (b)     Vesting Schedules:
         NOTE:  The vesting schedules below only apply to a Participant who has
         at least one Hour of Service during or after the 1989 Plan Year.  If
<PAGE>   11

         applicable, Participants who separated from Service prior to the 1989
         Plan Year will remain under the vesting schedule as in effect in the
         Plan prior to amendment for the Tax Reform Act of 1986.

                 [X]       (i)    Full and immediate Vesting.  Only in the
                                  event the Employer is acquired by merger,
                                  consolidation or otherwise, where more than
                                  50% of its shares of stock are acquired
                                  within one 12-month period by one or more
                                  related persons (within the meaning of Code
                                  Section 1563), or in the event the Employer
                                  otherwise ceases to function as an ongoing
                                  business concern.  In the event that the
                                  Employer becomes a part of a holding company
                                  system whereby the shareholders of the
                                  Employer become the shareholders of the
                                  holding company:  (1) the provisions of this
                                  paragraph shall not apply upon the transfer
                                  of shares as a part of the establishment of
                                  the holding company system by the Employer;
                                  and (2) the provisions of this paragraph
                                  shall apply to the share ownership of the
                                  holding company established by the Employer.

         account, as defined in Code Section 415(1)(2), which is part of a
         pension or annuity plan maintained by the Employer (these amounts are
         treated as Annual Additions to a Defined Contribution Plan though they
         arise under a Defined Benefit Plan), and

(e)      amounts derived from contributions paid or accrued after 1985, in
         taxable years ending after 1985, which are either attributable to

Required Beginning Date, the Applicable Calendar Year is the year such payments
commence.  If distribution is in the form of an immediate annuity purchased
after the Participant's death with the Participant's remaining interest, the
Applicable Calendar Year is the year of purchase.

1.5      APPLICABLE LIFE EXPECTANCY Used in determining the required minimum
distribution.  The life expectancy (or joint and last survivor expectancy)
calculated using the attained age of the Participant (or Designated Beneficiary)
as of the Participant's (or Designated Beneficiary's) birthday in the Applicable
Calendar Year reduced by one for each calendar year which has elapsed since the
date life expectancy was first calculated.  If life expectancy is being
recalculated, the Applicable Life Expectancy shall be the life expectancy as so
recalculated.  The life expectancy of a non-Spouse Beneficiary may not be
recalculated.

1.6      BREAK IN SERVICE A 12-consecutive month period during which an
Employee fails to complete more than 500 Hours of Service.

1.7      CODE The Internal Revenue Code of 1986, including any amendments
thereto.

1.8      COMPENSATION The Employer may select one of the following three
safe-harbor definitions of compensation in the Adoption Agreement.
Compensation shall only include amounts earned while a Participant if Plan Year
is chosen as the applicable computation period.

(a)      CODE SECTION 3401(a) WAGES.  Compensation is defined as wages within
         the meaning of Code Section 3401(a) for the purposes of Federal income
         tax withholding at the source but determined without regard to any
         rules that limit the remuneration included in wages based on the
         nature or location of the employment or the services performed [such
         as the exception for agricultural labor in Code Section 3401(a)(2)].

(b)      CODE SECTION 6041 AND 6051 WAGES.  Compensation is defined as wages as
         defined in Code Section 3401(a) and all other payments of compensation
         to an Employee by the Employer (in the course of the Employer's trade
         or business) for which the Employer is required to furnish the
         employee a written statement under Code Section 6041(d) and
         6051(a)(3).  Compensation must be determined without regard to any
         rules under Code Section 3401(a) that limit the remuneration included
         in wages based on the nature or location of the employment or the
         services performed [such as the exception for agricultural labor in
         Code Section 3401(a)(2)].

(c)      CODE SECTION 415 COMPENSATION.  For purposes of applying the
         limitations of Article X and Top-Heavy Minimums, the definition of
         Compensation shall be Code Section 415 Compensation as follows: a
         Participant's Earned Income, wages, salaries, and fees for
         professional services and other amounts received (without regard to
         whether or not an amount is paid in cash) for personal services
         actually rendered in the course of employment with the Employer
<PAGE>   24

         maintaining the Plan to the extent that the amounts are includible in
         gross income [including, but not limited to, commissions paid
         salesmen, compensation for services on the basis of a percentage of
         profits, commissions on insurance premiums, tips, bonuses, fringe
         benefits and reimbursements or other expense allowances under a
         nonaccountable plan (as described in Regulation 1.62 2(c)], and
         excluding the following:

         1.      Employer contributions to a plan of deferred compensation
                 which are not includible in the Employee's gross income for
                 the taxable year in which contributed, or Employer
                 contributions under a Simplified Employee Pension Plan or any
                 distributions from a plan of deferred compensation,

         2.      Amounts realized from the exercise of a non-qualified stock
                 option, or when restricted stock (or property) held by the
                 Employee either becomes freely transferable or is no longer
                 subject to a substantial risk of forfeiture,

         3.      Amounts realized from the sale, exchange or other disposition
                 of stock acquired under a qualified stock option; and

         4.      other amounts which received special tax benefits, or
                 contributions made by the Employer (whether or not under a
                 salary reduction agreement) towards the purchase of an annuity
                 contract described in Code Section 403(b) (whether or not the
                 contributions are actually excludible from the gross income of
                 the Employee).

For purposes of applying the limitations of Article X, Compensation for a
Limitation Year is the Compensation actually paid or made available during such
Limitation Year.  Notwithstanding the preceding sentence, Compensation for a
Participant in a defined contribution plan who is permanently and totally
disabled [as defined in Code Section 22(e)(3)] is the Compensation such
Participant would have received for the Limitation Year if the Participant had
been paid at the rate of Compensation paid immediately before becoming
permanently and totally disabled.  Such imputed Compensation for the disabled
Participant may be taken into account only if the participant is not a Highly
Compensated Employee [as defined in Code Section 414(q)] and contributions made
on behalf of such Participant are nonforfeitable when made.

If the Employer fails to pick the applicable period in the Adoption Agreement,
the Plan Year shall be used.  Unless otherwise specified by the Employer in the
Adoption Agreement, Compensation shall be determined as provided in 1.8(c).  In
Nonstandardized Adoption Agreements 003 and 004, the Employer may choose to
eliminate or exclude categories of Compensation which do not violate the
provisions of Code Sections 401(a)(4), 414(s) the regulations thereunder and
Revenue Procedure 89-65.

Beginning with 1989 Plan Years, the annual Compensation of each Participant
which may be taken into account for determining all benefits provided under the
Plan (including benefits under Article XIV) for any year shall not exceed
$200,000, as adjusted under Code Section 415(d).  In determining the
Compensation of a Participant for purposes of this limitation, the rules
<PAGE>   25

of Code Section 414(q)(6) shall apply, except in applying such rules, the term
"family" shall include only the spouse of the Participant and any lineal
descendants of the Participant who have not attained age 19 before the end of
the Plan year.  If, as a result of the application of such rules the adjusted
$200,000 limitation is exceeded, then (except for purposes of determining the
portion of Compensation up to the integration level if this Plan provides for
permitted disparity), the limitation shall be prorated among the affected
individuals in proportion to each such individual's Compensation as determined
under this section prior to the application of this limitation.

If a Plan has a Plan Year that contains fewer than 12 Calendar Months, then the
annual compensation limit for that period is an amount equal to the $200,000 as
adjusted for the calendar year in which the compensation period begins,
multiplied by a fraction the numerator of which is the number of full months in
the Short Plan Year and the denominator of which is 12.  If compensation for
any prior plan year is taken into account in determining an employee's
contributions or benefits for the current year, the compensation for such prior
year is subject to the applicable annual compensation limit in effect for that
prior year.  For this purpose, for years beginning before January 1, 1990, the
applicable annual compensation limit is $200,000.

Compensation shall not include deferred compensation other than contributions
through a salary reduction agreement to a cash or deferred plan under Code
Section 401 (k), a Simplified Employee Pension Plan under Code Section
402(h)(1)(B), a cafeteria plan under Code Section 125 or a tax-deferred annuity
under Code Section 403(b).  Unless elected otherwise by the Employer in the
Adoption Agreement, these deferred amounts will be considered as Compensation
for Plan purposes.  These deferred amounts are not counted as Compensation for
purposes of Articles X and XIV.  When applicable to a Self-Employed Individual,
Compensation shall mean Earned Income.

1.9      CUSTODIAN The Sponsor of this Prototype Plan, or if applicable, an
affiliate or successor, shall serve as Custodian, if a Custodian is appointed
in the Adoption Agreement.

1.10     DEFINED BENEFIT PLAN A Plan under which a Participant's benefit is
determined by a formula contained in the Plan and no individual accounts are
maintained for Participants.

1.11     DEFINED BENEFIT (PLAN) FRACTION A fraction, the numerator of which is
the sum of the Participant's Projected Annual Benefits under all the Defined
Benefit Plans (whether or not terminated) maintained by the Employer, and the
denominator of which is the lesser of 125 percent of the dollar limitation
determined for the Limitation Year under Code Sections 415(b) and (d) or 140
percent of the Highest Average Compensation, including any adjustments under
Code Section 415(b).

Transitional Rule: Notwithstanding the above, if the Participant was a
Participant as of the first day of the first Limitation Year beginning after
1986, in one or more Defined Benefit Plans maintained by the Employer which
were in existence on May 6, 1986, the denominator of this fraction will not be
less than 125 percent of the sum of the annual benefits under
<PAGE>   26

such plans which the Participant had accrued as of the close of the last
Limitation Year beginning before 1987, disregarding any changes in the terms
and conditions of the plan after May 5, 1986.  The preceding sentence applies
only if the Defined Benefit Plans individually and in the aggregate satisfied
the requirements of Section 415 for all Limitation Years beginning before 1987.

1.12     DEFINED CONTRIBUTION DOLLAR LIMITATION Thirty thousand dollars
($30,000) or if greater, one-fourth of the defined benefit dollar limitation
set forth in Code Section 415(b)(1) as in effect for the Limitation Year.

1.13     DEFINED CONTRIBUTION PLAN A Plan under which individual accounts are
maintained for each Participant to which all contributions, forfeitures,
investment income and gains or losses, and expenses are credited or deducted.
A Participant's benefit under such Plan is based solely on the fair market
value of his or her account balance.

1.14     DEFINED CONTRIBUTION (PLAN) FRACTION A Fraction, the numerator of
which is the sum of the Annual Additions to the Participant's account under all
the Defined Contribution Plans (whether or not terminated) maintained by the
Employer for the current and all prior Limitation Years (including the Annual
Additions attributable to the Participant's nondeductible Employee
contributions to all Defined Benefit Plans, whether or not terminated,
maintained by the Employer, and the Annual Additions attributable to all
Welfare Benefit Funds, as defined in paragraph 1.72 and individual medical
accounts, as defined in Code Section 415(1)(2), maintained by the Employer),
and the denominator of which is the sum of the maximum aggregate amounts for
the current and all prior Limitation Years of Service with the Employer
(regardless of whether a Defined Contribution Plan was maintained by the
Employer).  The maximum aggregate amount in the Limitation Year is the lesser
of 125 percent of the dollar limitation determined under Code Sections 415(b)
and (d) in effect under Code Section 415(c)(1)(A) or 35 percent of the
Participant's Compensation for such year.

Transitional Rule: If the Employee was a Participant as of the end of the first
day of the first Limitation Year beginning after 1986, in one or more Defined
Contribution Plans maintained by the Employer which were in existence on May 6,
1986, the numerator of this fraction will be adjusted if the sum of this
fraction and the Defined Benefit Fraction would otherwise exceed 1.0 under the
terms of this Plan.  Under the adjustment, an amount equal to the product of
(1) the excess of the sum of the fractions over 1.0 times (2) the denominator
of this fraction will be permanently subtracted from the numerator of this
fraction.  The adjustment is calculated using the fractions as they would be
computed as of the end of the last Limitation Year beginning before 1987, and
disregarding any changes in the terms and conditions of the Plan made after May
6, 1986, but using the Section 415 limitation applicable to the first
Limitation Year beginning on or after January 1, 1987.  The Annual Addition for
any Limitation Year beginning before 1987, shall not be re-computed to treat
all Employee Contributions as Annual Additions.

1.15     DESIGNATED BENEFICIARY The individual who is designated as the
beneficiary under the Plan in accordance with Code Section 401(a)(9) and the
regulations thereunder.
<PAGE>   27

1.16     DISABILITY An illness or injury of a potentially permanent nature,
expected to last for a continuous period of not less than 12 months, certified
by a physician selected by or satisfactory to the Employer which prevents the
Employee from engaging in any occupation for wage or profit for which the
Employee is reasonably fitted by training, education or experience.

1.17     DISTRIBUTION CALENDAR YEAR A calendar year for which a minimum
distribution is required.

1.18     EARLY RETIREMENT AGE The age set by the Employer in the Adoption
Agreement (but not less than 55), which is the earliest age at which a
Participant may retire and receive his or her benefits under the Plan.

1.19     EARNED INCOME Net earnings from self-employment in the trade or
business with respect to which the Plan is established, determined without
regard to items not included in gross income and the deductions allocable to
such items, provided that personal services of the individual are a material
income- producing factor.  Earned income shall be reduced by contributions made
by an Employer to a qualified plan to the extent deductible under Code Section
404.  For tax years beginning after 1989, net earnings shall be determined
taking into account the deduction for one-half of self-employment taxes allowed
to the Employer under Code Section 164(f) to the extent deductible.

1.20     EFFECTIVE DATE  The date on which the Employer's retirement plan or
amendment to such Plan becomes effective.

1.21     ELECTION PERIOD The period which begins on the first day of the Plan
Year in which the Participant attains age 35 and ends on the date of the
Participant's death.  If a Participant separates from Service prior to the
first day of the Plan Year in which age 35 is attained, the Election Period
shall begin on the date of separation, with respect to the account balance as
of the date of separation.

1.22     EMPLOYEE  Any person employed by the Employer (including Self-Employed
Individuals and partners), all Employees of a member of an affiliated service
group [as defined in Code Section 414(m)], Employees of a controlled group of
corporations [as deemed in Section 414(b) of the Code], all Employees of any
incorporated or unincorporated trade or business which is under common control
[as defined in Section 414(c) of the Code], Leased Employees [as defined in
Code Section 414(n)] and any Employee required to be aggregated by Code Section
414(o).  All such Employees shall be treated as employed by a single Employer.

1.23     EMPLOYER  The Self-Employed Individual, partnership, corporation or
other organization which adopts this Plan including any firm that succeeds the
Employer and adopts this Plan.  For purposes of Article X, Limitations on
Allocations, Employer shall mean the Employer that adopts this Plan, and all
members of a controlled group of corporations [as defined in Code Section
414(b) as modified by Section 415(h)], all commonly controlled trades or
businesses [as defined in Section 414(c) as modified by Section 415(h)] or
affiliated service groups [as defined in Section 414(m)] of which the adopting
Employer is a part, and other entity required to be
<PAGE>   28

aggregated with the Employer pursuant to regulations under Code Section 414(o).

1.24     ENTRY DATE  The date on which an Employee commences participation in
the Plan as determined by the Employer in the Adoption Agreement.  Unless the
Employer specifies otherwise in the Adoption Agreement, Entry into the Plan
shall be on the first day of the Plan Year or the first day of the seventh
month of the Plan Year coinciding with or following the date on which an
Employee meets the eligibility requirements.

1.25     EXCESS AMOUNT  The excess of the Participant's Annual Additions for
the Limitation Year over the Maximum Permissible Amount.

1.26     FIRST DISTRIBUTION CALENDAR YEAR  For distributions beginning before
the Participant's death, the First Distribution Calendar Year is the calendar
year immediately preceding the calendar year which contains the Participant's
Required Beginning Date.  For distributions beginning after the Participant's
death, the First Distribution Calendar Year is the calendar year in which
distributions are required to begin pursuant to paragraph 7.10.

1.27     FUND  All contributions received by the Trustee/Custodian under this
Plan and Trust/Custodial Account, investments thereof and earnings and
appreciation thereon.

1.28     HIGHEST AVERAGE COMPENSATION The average Compensation for the three
consecutive Years of Service with the Employer that produces the highest
average.  A Year of Service with the Employer is the 12-consecutive month
period defined in the Adoption Agreement.

1.29     HOUR OF SERVICE

(a)      Each hour for which an Employee is paid, or entitled to payment, for
         the performance of duties for the Employer.  These hours shall be
         credited to the Employee for the computation period in which the
         duties are performed; and

(b)      Each hour for which an Employee is paid, or entitled to payment, by
         the Employer 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), layoff, jury duty, military duty or leave of absence.  No
         more than 501 Hours of Service shall be credited under this paragraph
         for any single continuous period (whether or not such period occurs in
         a single computation period).  Hours under this paragraph shall be
         calculated and credited pursuant to Section 2530.2006-2 of the
         Department of Labor Regulations which are incorporated herein by this
         reference; and

(c)      Each hour for which back pay, irrespective of mitigation of damages,
         is either awarded or agreed to by the Employer.  The same Hours of
         Service shall not be credited both under paragraph (a) or paragraph
         (b), as the case may be, and under this paragraph (c).  These hours
         shall be credited to the Employee for the computation period or
<PAGE>   29

         periods to which the award or agreement pertains rather than the
         computation period in which the award, agreement or payment is made.

(d)      Hours of Service shall be credited for employment with the Employer
         and with other members of an affiliated service group [as defined in
         Code Section 414(m)], a controlled group of corporations [as defined
         in Code Section 414(b)], or a group of trades or businesses under
         common control [as defined in Code Section 414(c)] of which the
         adopting Employer is a member, and any other entity required to be
         aggregated with the Employer pursuant to Code Section 414(o) and the
         regulations thereunder.  Hours of Service shall also be credited for
         any individual considered an Employee for purposes of this Plan under
         Code Section 414(n) or Code Section 414(o) and the regulations
         thereunder.

(e)      Solely for purposes of determining whether a Break in Service, as
         defined in paragraph 1.6, for participation and vesting purposes has
         occurred in a computation period, an individual who is absent from
         work for maternity or paternity reasons shall receive credit for the
         Hours of Service which would otherwise have been credited to such
         individual but for such absence, or in any case in which such hours
         cannot be determined, 8 Hours of Service per day of such absence.  For
         purposes of this paragraph, an absence from work for maternity or
         paternity reasons means an absence by reason of the pregnancy of the
         individual, by reason of a birth of a child of the individual, by
         reason of the placement of a child with the individual in connection
         with the adoption of such child by such individual, or for purposes of
         caring for such child for a period beginning immediately following
         such birth or placement.  The Hours of Service credited under this
         paragraph shall be credited in the computation period in which the
         absence begins if the crediting is necessary to prevent a Break in
         Service in that period, or in all other cases, in the following
         computation period.  No more than 501 hours will be credited under
         this paragraph.

(f)      Unless specified otherwise in the Adoption Agreement, Hours of Service
         shall be determined on the basis of the actual hours for which an
         employee is paid or entitled to payment

1.30     KEY EMPLOYEE Any Employee or former Employee (and the beneficiaries of
such employee) who at any time during the determination period was an officer
of the Employer if such individual's annual compensation exceeds 50% of the
dollar limitation under Code Section 415(b)(1)(A) (the defined benefit maximum
annual benefit), an owner (or considered an owner under Code Section 318) of
one of the ten largest interests in the employer if such individual's
compensation exceeds 100% of the dollar limitation under Code Section
415(c)(1)(A), a 5% owner of the Employer, or a 1 % owner of the Employer who
has an annual compensation of more than $150,000.  For purposes of determining
who is a Key Employee, annual compensation shall mean Compensation as defined
for Article X, but including amounts deferred through a salary reduction
agreement to a cash or deferred plan under Code Section 401(k), a Simplified
Employee Pension Plan under Code Section 402(h)(1)(B), a cafeteria plan under
Code Section 125 or a tax-deferred annuity under Code Section 403(b).  The
determination period is the Plan Year containing the Determination Date and the
four preceding Plan Years.
<PAGE>   30

The determination of who is a Key Employee will be made in accordance with Code
Section 416(i)(1) and the regulations thereunder.

1.31     LEASED EMPLOYEE Any person (other than an Employee of the recipient)
who pursuant to an agreement between the recipient and any other person
("leasing organization") has performed services for the recipient [or for the
recipient and related persons determined in accordance with Code Section
414(n)(6)] on a substantially full-time basis for a period of at least one
year, and such services are of a type historically performed by Employees in
the business field of the recipient Employer.

1.32     LIMITATION YEAR  The calendar year or such other 12- consecutive month
period designated by the Employer in the Adoption Agreement for purposes of
determining the maximum Annual Addition to a Participant's account.  All
qualified plans maintained by the Employer must use the same Limitation Year.
If the Limitation Year is amended to a different 12-consecutive month period,
the new Limitation Year must begin on a date within the Limitation Year in
which the amendment is made.

1.33     MANDATORY CONTRIBUTION  An Employee contribution which was not
tax-deductible when made and which was required for participation in the Plan.
These contributions may no longer be made to the Plan, for Plan Years beginning
after the Plan Year in which this Plan is adopted (or restated) by the
Employer.

1.34     MASTER OR PROTOTYPE PLAN A plan, the form of which is the subject of a
favorable opinion letter from the Internal Revenue Service.

1.35     MAXIMUM PERMISSIBLE AMOUNT  The maximum Annual Addition that may be
contributed or allocated to a Participant's account under the plan for any
Limitation Year shall not exceed the lesser of:

(a)      the Defined Contribution Dollar Limitation, or

(b)      25% of the Participant's Compensation for the Limitation Year.

The compensation limitation referred to in (b) shall not apply to any
contribution for medical benefits [within the meaning of Code Section 401(h) or
Code Section 419A(f)(2)] which is otherwise treated as an Annual Addition under
Code Section 415(1)(1) or 419(d)(2).  If a short Limitation Year is created
because of an amendment changing the Limitation Year to a different
12-consecutive month period, the Maximum Permissible Amount will not exceed the
Defined Contribution Dollar Limitation multiplied by the following fraction:
Number of months in the short Limitation Year divided by 12.

1.36     NET PROFIT The current and accumulated operating earnings of the
Employer before Federal and State income taxes, excluding nonrecurring or
unusual items of income, and before contributions to this and any other
qualified plan of the Employer.  Alternatively, the Employer may fix another
definition in the Adoption Agreement.

1.37     NORMAL RETIREMENT AGE  The age set by the Employer in the Adoption
Agreement at which a Participant may retire and receive his or her benefits
under the Plan.
<PAGE>   31

1.38     OWNER-EMPLOYEE A sole proprietor, or a partner owning more than 10% of
either the capital or profits interest of the partnership.

1.39     PAIRED PLANS  Two or more Plans maintained by the Sponsor designed so
that a single or any combination of Plans adopted by an Employer will meet the
antidiscrimination rules, the contribution and benefit limitations, and the

is participating in the Plan.

1.41     PARTICIPANT'S BENEFIT  The account balance as of the last Valuation
Date in the calendar year immediately preceding the Distribution Calendar Year
(valuation calendar year), increased by the amount of any contributions or
forfeitures allocated to the account balance as of the dates in the valuation
calendar year after the Valuation Date and decreased by distributions made in
the valuation calendar year after the Valuation Date.  A special exception
exists for the second distribution Calendar Year.  For purposes of this
paragraph, if any portion of the minimum distribution for the First
Distribution Calendar Year is made in the second Distribution Calendar Year on
or before the Required Beginning Date, the amount of the minimum distribution
made in the second distribution calendar year shall be treated as if it had
been made in the immediately preceding Distribution Calendar Year.

1.42     PERMISSIVE AGGREGATION GROUP  Used for Top-Heavy testing purposes, it
is the Required Aggregation Group of plans plus any other plan or plans of the
Employer which, when considered as a group with the Required Aggregation Group,
would continue to satisfy the requirements of Code Sections 401(a)(4) and 410.

1.43     PLAN  The Employer's retirement plan as embodied herein and in the
Adoption Agreement.

1.44     PLAN ADMINISTRATOR  The Employer.

1.45     PLAN YEAR  The 12-consecutive month period designated by the Employer
in the Adoption Agreement.

1.46     PRESENT VALUE  When determining the Present Value of accrued benefits,
with respect to any Defined Benefit Plan maintained by the Employer for
Top-Heavy test and limitation on allocation purposes, interest and mortality
rates shall be determined in accordance with the provisions of the respective
plan.  If applicable, interest and mortality assumptions will be specified in
Section 10 of Adoption Agreements 001 through 004 and Section 7 of Adoption
Agreements 005 and 006.

1.47     PROJECTED ANNUAL BENEFIT  Used to test the maximum benefit which may
be obtained from a combination of retirement plans, it is the annual retirement
benefit (adjusted to an actuarial equivalent straight life annuity if such
benefit is expressed in a form other than a straight life annuity or Qualified
Joint and Survivor Annuity) to which the Participant would be entitled under
the terms of a Defined Benefit Plan or plans, assuming:
<PAGE>   32

(a)      the Participant will continue employment until Normal Retirement Age
         under the plan (or current age, if later), and

(b)      the Participant's Compensation for the current Limitation Year and all
         other relevant factors used to determine benefits under the plan will
         remain constant for all future Limitation Years.

1.48     QUALIFIED DEFERRED COMPENSATION PLAN  Any pension, profit-sharing,
stock bonus, or other plan which meets the requirements of Code Section 401 and
includes a trust exempt from tax under Code Section 501(a) and any annuity plan

Year, the last day of that year.

1.65     TOP-HEAVY PLAN  For any Plan Year beginning after 1983, the Employer's
Plan is top-heavy if any of the following conditions exist:

(a)      If the Top-Heavy Ratio for the Employer's Plan exceeds 60% and this
         Plan is not part of any Required Aggregation Group or Permissive
         Aggregation Group of Plans.

(b)      If the Employer's plan is a part of a Required Aggregation Group of
         plans but not part of a Permissive Aggregation Group and the Top-Heavy
         Ratio for the group of plans exceeds 60%.

(c)      If the Employer's plan is a part of a Required Aggregation Group and
         part of a Permissive Aggregation Group of plans and the Top-Heavy
         Ratio for the Permissive Aggregation Group exceeds 60%.

1.66     TOP-HEAVY RATIO

(a)      If the Employer maintains one or more Defined Contribution plans
         (including any Simplified Employee Pension Plan) and the Employer has
         not maintained any Defined Benefit Plan which during the 5-year period
         ending on the Determination Date(s) has or has had accrued benefits,
         the Top-Heavy Ratio for this Plan alone, or for the Required or
         Permissive Aggregation Group as appropriate, is a fraction,

         (1)     the numerator of which is the sum of the account balances of
                 all Key Employees as of the Determination Date(s) [including
                 any part of any account balance distributed in the 5-year
                 period ending on the Determination Date(s)], and
<PAGE>   35


         (2)     the denominator of which is the sum of all account balances
                 [including any part of any account balance distributed in the
                 5-year period ending on the Determination Date(s)], both
                 computed in accordance with Code Section 416 and the
                 regulations thereunder.

         Both the numerator and denominator of the Top-Heavy Ratio are
         increased to reflect any contribution not actually made as of the
         Determination Date, but which is required to be taken into account on
         that date under Code Section 416 and the regulations thereunder.

(b)      If the Employer maintains one or more Defined Contribution Plans
         (including any Simplified Employee Pension Plan) and the Employer
         maintains or has maintained one or more Defined Benefit Plans which
         during the 5-year period ending on the Determination Date(s) has or
         has had any accrued benefits, the Top-Heavy Ratio for any Required or
         Permissive Aggregation Group as appropriate is a fraction,

         (1)     the numerator of which is the sum of account balances under
                 the aggregated Defined Contribution Plan or Plans for all Key
                 Employees,determined in accordance with (a) above, and the
                 Present Value of accrued benefits under the aggregated Defined
                 Benefit Plan or Plans for all Key Employees as of the
                 Determination Date(s), and

         (2)     the denominator of which is the sum of the account balances
                 under the aggregated Defined Contribution Plan or Plans for
                 all Participants, determined in accordance with (a) above, and
                 the Present Value of accrued benefits under the Defined
                 Benefit Plan or Plans for all Participants as of the
                 Determination Date(s), all determined in accordance with Code
                 Section 416 and the regulations thereunder.

         The accrued benefits under a Defined Benefit Plan in both the
         numerator and denominator of the Top-Heavy Ratio are increased for any
         distribution of an accrued benefit made in the 5-year period ending on
         the Determination Date.

(c)      For purposes of (a) and (b) above, the value of account balances and
         the Present Value of accrued benefits will be determined as of the
         most recent Valuation Date that falls within or ends with the 12-month
         period ending on the Determination Date, except as provided in Code
         Section 416 and the regulations thereunder for the first and second
         plan years of a Defined Benefit Plan.  The account balances and
         accrued benefits of a Participant (1) who is not a Key Employee but
         who was a Key Employee in a prior year, or (2) who has not been
         credited with at least one Hour of Service with any Employer
         maintaining the Plan at any time during the 5-year period ending on
         the Determination Date, will be disregarded.  The calculation of the
         Top-Heavy Ratio, and the extent to which distributions, rollovers, and
         transfers are taken into account, will be made in accordance with Code
         Section 416 and the regulations thereunder.  Qualified Voluntary
         Employee Contributions will not be taken into account for purposes of
         computing the Top-Heavy Ratio.  When aggregating plans, the value of
         account balances and accrued benefits will be calculated with
<PAGE>   36

         reference to the Determination Dates that fall within the same
         calendar year.  The accrued benefit of a Participant other than a Key
         Employee shall be determined under (1) the method, if any, that
         uniformly applies for accrual purposes under all Defined Benefit Plans
         maintained by the Employer, or (2) if there is no such method, as if
         such benefit accrued not more rapidly than the slowest accrual rate
         permitted under the fractional rule of Code Section 411(b)(1)(C).

1.67     TRANSFER CONTRIBUTION  A non-taxable transfer of a Participant's
benefit directly from a Qualified Deferred Compensation Plan to this Plan

1.69     VALUATION DATE The last day of the Plan Year or such other date as
agreed to by the Employer and the Trustee/Custodian on which Participant
accounts are revalued in accordance with Article V hereof.  For Top-Heavy
purposes, the date selected by the Employer as of which the Top-Heavy Ratio is
calculated.

1.70     VESTED ACCOUNT BALANCE  The aggregate value of the Participant's
vested account balances derived from Employer and Employee contributions
(including Rollovers), whether vested before or upon death, including the
proceeds of insurance contracts, if any, on the Participant's life.  The
provisions of Article VIII shall apply to a Participant who is vested in
amounts attributable to Employer contributions, Employee contributions (or
both) at the time of death or distribution.

For purposes of paragraph 8.7, Vested Account Balance shall mean, in the case
of a money purchase pension plan, the Participant's separate account balance
attributable solely to Qualified Voluntary Contributions.  For profit-sharing
plans the above definition shall apply.

1.71     VOLUNTARY CONTRIBUTION  An Employee contribution which is not
tax-deductible and which is not required as a condition for participation in
the Plan.  Such contributions are no longer permitted under this Prototype
Plan, for Plan Years beginning after the Plan Year in which this Plan is
adopted (or restated) by the Employer.

1.72     WELFARE BENEFIT FUND  Any fund that is part of a plan of the Employer,
or has the effect of a plan, through which the Employer provides welfare
benefits to Employees or their beneficiaries.  For these purposes, Welfare
Benefits means any benefit other than those with respect to which Code Section
83(h) (relating to transfers of property in connection with the performance of
services), Code Section 404 (relating to deductions for contributions to an
Employees' trust or annuity and Compensation under a deferred payment plan),
Code Section 404A (relating to certain foreign deferred compensation plans),
and the election under Code Section 463 (relating to the accrual of vacation
pay) apply.  For purposes of this paragraph a "Fund" is any social club,
voluntary employee benefit association, supplemental unemployment benefit trust
or qualified group legal service organization described in Code Section
501(c)(7), (9), (17) or (20); any trust, corporation, or other organization not
exempt from income tax, or to the extent provided in regulations, any account

                            ELIGIBILITY REQUIREMENTS

2.1      PARTICIPATION  Employees who meet the eligibility requirements in the
Adoption Agreement on the Effective Date of the Plan shall become Participants
as of the Effective Date of the Plan.  If so elected in the Adoption Agreement,
all Employees employed on the Effective Date of the Plan may participate, even
if they have not satisfied the Plan's specified eligibility requirements.
Other Employees shall become Participants on the Entry Date specified in the
Adoption Agreement.  Depending on the Plan's eligibility requirements, the
entry date may actually be earlier than the date on which the Employee
satisfies the eligibility requirements.  The Employee must satisfy the
eligibility requirements specified in the Adoption Agreement and be employed on
the Entry Date to become a Participant in the Plan.  In the event an Employee
who is not a member of the eligible class of Employees becomes a member of the
eligible class, such Employee shall participate immediately if such Employee
has satisfied the minimum age and service requirements and would have
previously become a Participant had he or she been in the eligible class.  A
former Participant shall again become a Participant upon returning to the
employ of the Employer as of the next Entry Date.

2.2      CHANGE IN CLASSIFICATION OF EMPLOYMENT  In the event a Participant
becomes ineligible to participate because he or she is no longer a member of an
eligible class of Employees, such Employee shall participate upon his or her
return to an eligible class of Employees.

2.3      COMPUTATION PERIOD  To determine Years of Service and Breaks in
Service for purposes of eligibility, the 12-consecutive month period shall
commence on the date on which an Employee first performs an Hour of Service for
the Employer and each anniversary thereof, such that the succeeding
12-consecutive month period commences with the employee's first anniversary of
employment and so on.

2.4      EMPLOYMENT RIGHTS  Participation in the Plan shall not confer upon a
Participant any employment rights, nor shall it interfere with the Employer's
right to terminate the employment of any Employee at any time.

2.5      SERVICE WITH CONTROLLED GROUPS  All Years of Service with other
members of a controlled group of corporations [as defined in Code Section
414(b)], trades or businesses under common control [as defined in Code Section
414(c)], or members of an affiliated service group [as defined in Code Section
414(m)] shall be credited for purposes of determining an Employee's eligibility
to participate.

2.6      OWNER-EMPLOYEES  If this Plan provides contributions or benefits for
one or more Owner-Employees who control both the business for which this Plan
is established and one or more other trades or businesses, this Plan and the
Plan established for other trades or businesses must, when looked
<PAGE>   38

at as a single Plan, satisfy Code Sections 401(a) and (d) for the Employees of
this and all other trades or businesses.

If the Plan provides contributions or benefits for one or more Owner-Employees
who control one or more other trades or businesses, the Employees of the other
trades or businesses must be included in a Plan which satisfies Code Sections
401 (a) and (d) and which provides contributions and benefits not less
favorable than provided for Owner-Employees under this Plan.

If an individual is covered as an Owner-Employee under the plans of two or more
trades or businesses which are not controlled and the individual controls a
trade or business, then the contributions or benefits of the Employees under
the plan of the trades or businesses which are controlled must be as favorable
as those provided for him under the most favorable plan of the trade or
business which is not controlled.

For purposes of the preceding sentences, an Owner-Employee, or two or more
Owner-Employees, will be considered to control a trade or business if the
Owner-Employee, or two or more Owner-Employees together:

(a)      own the entire interest in an unincorporated trade or business, or

(b)      in the case of a partnership, own more than 50% of either the capital
         interest or the profits interest in the partnership.

For purposes of the preceding sentence, an Owner-Employee, or two or more
Owner-Employees shall be treated as owning any interest in a partnership which
is owned, directly or indirectly, by a partnership which such Owner-Employee,
or such two or more Owner-Employees, are considered to control within the
meaning of the preceding sentence.

2.7      LEASED EMPLOYEES Any Leased Employee shall be treated as an Employee
of the recipient Employer, however, contributions or benefits provided by the
leasing organization which are attributable to services performed for the
recipient Employer shall be treated as provided by the recipient Employer.  A
Leased Employee shall not be considered an Employee of the recipient if such
Employee is covered by a money purchase pension plan providing:

(a)      a non-integrated Employer contribution rate of at least 10% of
         Compensation, [as defined in Code Section 415(c)(3) but including
         amounts, contributed by the Employer pursuant to a salary reduction
         agreement, which are excludable from the Employee's gross income under
         a cafeteria plan covered by Code Section 125, a cash or deferred
         profit-sharing plan under Section 401 (k) of the Code, a Simplified
         Employee Pension Plan under Code Section 402(h)(1)(B) and a tax-
         sheltered annuity under Code Section 403(b)],

(b)      immediate participation, and

(c)      full and immediate vesting.
<PAGE>   39

This exclusion is only available if Leased Employees do not constitute more
than twenty percent (20%) of the recipient's non-highly compensated work force.

                             EMPLOYER CONTRIBUTIONS

3.1      AMOUNT  The Employer intends to make periodic contributions to the
Plan in accordance with the formula or formulas selected in the Adoption
Agreement.  However, the Employer's contribution for any Plan Year shall be
subject to the limitations on allocations contained in Article X.

3.2      EXPENSES AND FEES  The Employer shall also be authorized to reimburse
the Fund for all expenses and fees incurred in the administration of the Plan
or Trust/Custodial Account and paid out of the assets of the Fund. Such expenses
shall include, but shall not be limited to, fees for professional services,
printing and postage. Brokerage Commissions may not be reimbursed.

3.3      RESPONSIBILITY FOR CONTRIBUTIONS  Neither the Trustee/Custodian nor
the Sponsor shall be required to determine if the Employer has made a
contribution or if the amount contributed is in accordance with the Adoption
Agreement or the Code.  The Employer shall have sole responsibility in this
regard.  The Trustee/Custodian shall be accountable solely for contributions
actually received by it within the limits of Article XI.

3.4      RETURN OF CONTRIBUTIONS  Contributions made to the Fund by the
Employer shall be irrevocable except as provided below:

(a)      Any contribution forwarded to the Trustee/Custodian because of a
         mistake of fact, provided that the contribution is returned to the
         Employer within one year of the contribution.

(b)      In the event that the Commissioner of Internal Revenue determines that
         the Plan is not initially qualified under the Internal Revenue Code,
         any contribution made incident to that initial qualification by the
         Employer must be returned to the Employer within one year after the
         date the initial qualification is denied, but only if the application
         for the qualification is made by the time prescribed by law for filing
         the Employer's return for the taxable year in which the Plan is
         adopted, or such later date as the Secretary of the Treasury may
         prescribe.

(c)      Contributions forwarded to the Trustee/Custodian are presumed to be
         deductible and are conditioned on their deductibility.  Contributions
         which are determined to not be deductible will be returned to the
         Employer.

                             EMPLOYEE CONTRIBUTIONS
<PAGE>   40


4.1      VOLUNTARY CONTRIBUTIONS  An Employee may no longer make Voluntary
Contributions to the Plan established hereunder for Plan Years beginning after
the Plan Year in which this plan is adopted or restated by the Employer.
Employee Contributions for Plan Years beginning after 1986, together with any
matching contributions as defined in Code Section 401(m), will be limited so as
to meet the antidiscrimination test of Section 401(m).  Voluntary and/or
Mandatory Contributions already made may stay in the Trust Fund/Custodial
Account.

4.2      QUALIFIED VOLUNTARY CONTRIBUTIONS  A Participant may no longer make
Qualified Voluntary Contributions to the Plan.  Amounts already contributed may
stay in the Trust Fund/Custodial Account until distributed to the Participant.
Such amounts will be maintained in a separate account which will be
nonforfeitable at all times.  The account will share in the gains and losses of
the Trust in the same manner as described at paragraph 5.4 of the Plan.  No
part of the Qualified Voluntary Contribution account will be used to purchase
life insurance.  Subject to Article VIII, Joint and Survivor Annuity
Requirements (if applicable), the Participant may withdraw any part of the
Qualified Voluntary Contribution account by making a written application to the
Plan Administrator.

4.3      ROLLOVER CONTRIBUTION  Unless provided otherwise in the Adoption
Agreement, a Participant may make a Rollover Contribution to any Defined
Contribution Plan established hereunder of all or any part of an amount
distributed or distributable to him or her from a Qualified Deferred
Compensation Plan provided:

(a)      the amount distributed to the Participant is deposited to the Plan no
         later than the sixtieth day after such distribution was received by
         the Participant,

(b)      the amount distributed is not one of a series of substantially equal
         periodic payments made for the life (or life expectancy) of the
         Participant or the joint lives (or joint life expectancies) of the
         Participant and the Participant's Designated Beneficiary, or for a
         specified period of ten years or more,

(c)      the amount distributed is not required under section 401(a)(9) of the
         Code,

(d)      if the amount distributed included property such property is rolled
         over, or if sold the proceeds of such property may be rolled over,

(e)      the amount distributed is not includible in gross income (determined
         without regard to the exclusion for net unrealized appreciation with
         respect to employer securities).

In addition, if the Adoption Agreement allows Rollover Contributions, the Plan
will also accept any Eligible Rollover Distribution (as defined at paragraph
1.55) directly to the Plan.

Rollover Contributions, which relate to distributions prior to January 1, 1993,
must be made in accordance with paragraphs (a) through (e) and additionally
meet the requirements of paragraph (f):
<PAGE>   41

(f)      The distribution from the Qualified Deferred Compensation Plan
         constituted the Participant's entire interest in such Plan and was
         distributed within one taxable year to the Participant:

         (1)     on account of separation from Service, a Plan termination, or
                 in the case of a profit-sharing or stock bonus plan, a
                 complete discontinuance of contributions under such plan
                 within the meaning of Section 402(a)(6)(A) of the Code, or

         (2)     in one or more distributions which constitute a qualified lump
                 sum distribution within the meaning of Code Section
                 402(e)(4)(A), determined without reference to subparagraphs
                 (B) and (H).

Such Rollover Contribution may also be made through an Individual Retirement
Account qualified under Code Section 408 where the IRA was used as a conduit
from the Qualified Deferred Compensation Plan, the Rollover Contribution is
made in accordance with the rules provided under paragraphs (a) through (e) and
the Rollover Contribution does not include any regular IRA contributions, or
earnings thereon, which the Participant may have made to the IRA.  Rollover
Contributions, which relate to distributions prior to January 1, 1993, may be
made through an IRA in accordance with paragraphs (a) through (f) and
additional requirements as provided in the previous sentence.  The
Trustee/Custodian shall not be held responsible for determining the tax-free
status of any Rollover Contribution made under this Plan.

4.4      TRANSFER CONTRIBUTION  Unless provided otherwise in the Adoption
Agreement, a Participant may, subject to the provisions of paragraph 4.5, also
arrange for the direct transfer of his or her benefit from a Qualified Deferred
Compensation Plan to this Plan.  For accounting and record keeping purposes,
Transfer Contributions shall be treated in the same manner as Rollover
Contributions.

4.5      EMPLOYER APPROVAL OF TRANSFER CONTRIBUTIONS  The Employer maintaining
a safe-harbor Profit-Sharing Plan in accordance with the provisions of
paragraph 8 7, acting in a nondiscriminatory manner, may in its sole discretion
refuse to allow Transfer Contributions to its profit-sharing plan, if such
contributions are directly or indirectly being transferred from a defined
benefit plan, a money purchase pension plan (including a target benefit plan),
a stock bonus plan, or another profit- sharing plan which would otherwise
provide for a life annuity form of payment to the Participant.

4.6      DIRECT ROLLOVER OF BENEFITS  Notwithstanding any provision of the plan
to the contrary that would otherwise limit a Participant's election under this
Paragraph, for distributions made on or after January 1,1993, a Participant may
elect, at the time and in the manner prescribed by the Plan Administrator, to
have any portion of an Eligible Rollover Distribution paid directly to an
Eligible Retirement Plan shall be distributed to the Participant.  For purposes
of this Paragraph, a Surviving Spouse or a spouse or former spouse who is an
alternate payee under a Qualified Domestic Relations Order as defined in
section 414(p) of the Code, will be permitted to elect to have any Eligible
Rollover Distribution paid directly
<PAGE>   42

to an individual retirement account (IRA) or an individual retirement annuity
(IRA).

The plan provisions otherwise applicable to distributions continue to apply to
Rollover and Transfer Contributions.


                                   ARTICLE V

                              PARTICIPANT ACCOUNTS


5.1      SEPARATE ACCOUNTS  The Employer shall establish a separate bookkeeping
account for each Participant showing the total value of his or her interest in
the Fund.  Each Participant's account shall be separated for bookkeeping
purposes into the following sub-accounts:

(a)      Employer contributions.

(b)      Mandatory Contributions (if previously accepted).

(c)      Voluntary Contributions (if previously accepted), and additional
         amounts including, if applicable, either repayments of loans
         previously defaulted on and treated as "deemed distributions" [on
         which a tax report has been issued], and amounts paid out upon a
         separation from service which have been included in income and which
         are repaid after being re-hired by the Employer.

(d)      Qualified Voluntary Contributions (if previously accepted).

(e)      Rollover Contributions and Transfer Contributions.

5.2      ADJUSTMENTS TO PARTICIPANT ACCOUNTS  As of each Valuation Date of the
Plan, the Employer shall add to each account:

(a)      the Participant's share of the Employer's contribution and forfeitures
         as determined in the Adoption Agreement,

(b)      any Voluntary, Rollover or Transfer Contributions made by the
         Participant,

(c)      any repayment of amounts previously paid out to a Participant upon a
         separation from Service and repaid by the Participant since the last
         Valuation Date, and

(d)      the Participant's proportionate share of any investment earnings and
         increase in the fair market value of the Fund since the last Valuation
         Date, as determined at paragraph 5.4.

The Employer shall deduct from each account:

(e)      any withdrawals or payments made from the Participant's account since
         the last Valuation Date, and
<PAGE>   43

(f)      the Participant's proportionate share of any decrease in the fair
         market value of the Fund since the last Valuation Date, as determined
         at paragraph 5.4.

5.3      ALLOCATING EMPLOYER CONTRIBUTIONS  The Employer's contribution shall
be allocated to Participants in accordance with the allocation formula selected
by the Employer in the Adoption Agreement, and the minimum contribution and
allocation requirements for Top-Heavy Plans.  Beginning with the 1990 Plan Year
and thereafter, for plans on Standardized Adoption Agreements 001,002,005 and
006, Participants who are credited with more than 500 Hours of Service or are
employed on the last day of the Plan Year must receive a full allocation of
Employer contributions.  In Nonstandardized Adoption Agreements 003 and 004,
Employer contributions shall be allocated to the accounts of Participants
employed by the Employer on the last day of the Plan Year.  In the case of a
non-Top-Heavy, Nonstandardized Plan, Participants must also have completed a
Year of Service unless otherwise specified in the Adoption Agreement.  For
Nonstandardized Adoption Agreements 003 and 004, the Employer may only apply
the last day of the Plan Year and Year of Service requirements if the Plan
satisfies the requirements of Code Sections 401(a)(26) and 410(b) and the
regulations thereunder.  If when applying the last day and Year of Service
requirements the Plan fails to satisfy the aforementioned requirements,
additional Participants will be eligible to receive an allocation of Employer
Contributions until the requirements are satisfied.  Participants who are
credited with a Year of Service, but not employed at Plan Year end are the
first category of additional Participants eligible to receive an allocation.
If the requirements are still not satisfied, Participants credited with more
than 500 Hours of Service and employed at Plan Year end are the next category
of Participants eligible to receive an allocation.  Finally, if necessary to
satisfy the said requirements, any Participant credited with more than 500
Hours of Service will be eligible for an allocation of Employer Contributions.

5.4      ALLOCATING INVESTMENT EARNINGS AND LOSSES  A Participant's share of
investment earnings and any increase or decrease in the fair market value of
the Fund shall be based on the proportionate value of all active accounts
(other than accounts with segregated investments) as of the last Valuation Date
minus withdrawals, minus fees, plus/minus transfers, and plus the average
balance, as defined by the Plan Administrator, of the current period's
contributions and loan payments except for Employer contributions made on an
annual basis after the end of the Plan Year since the last Valuation Date.
Account balances not yet forfeited shall receive an allocation of earnings
and/or losses.  Accounts with segregated investments shall receive only the
income or loss on such segregated investments.

Alternatively, at the Plan Administrator's option, all financial activity will
be credited with an allocation of the actual investment earnings and gains and
losses from the actual date of deposit of each such activity until the end of
the period.  Accounts with segregated investments shall receive only the income
or loss on such segregated investments.  In no event shall the selection of a
method of allocating gains and losses be used to discriminate in favor of the
Highly Compensated Employees.
<PAGE>   44

5.5      PARTICIPANT STATEMENTS  Upon completing the allocations described
above for the Valuation Date coinciding with the end of the Plan Year, the
Employer shall prepare a statement for each Participant showing the additions
to and subtractions from his or her account since the last such statement and
the fair market value of his or her account as of the current Valuation Date.
Employers so choosing may prepare Participant statements for each Valuation
Date.


                                   ARTICLE VI

                     RETIREMENT BENEFITS AND DISTRIBUTIONS


6.1      NORMAL RETIREMENT BENEFITS  A Participant shall be entitled to receive
the balance held in his or her account from Employer contributions upon
reaching Normal Retirement Age or at such earlier dates as the provisions of
this Article VI may allow.  If the Participant elects to continue working past
his or her Normal Retirement Age, he or she will continue as an active Plan
Participant.  Unless the Employer elects otherwise in the Adoption Agreement,
distribution shall be made to such Participant at his or her request prior to
his or her actual retirement date.  Settlement shall be made in the normal
form, or if elected, in one of the optional forms of payment provided below.

6.2      EARLY RETIREMENT BENEFITS If the Employer so provides in the Adoption
Agreement, an early retirement benefit will be available to individuals who
meet the age and Service requirements.  An individual who meets the Early
Retirement Age requirements and separates from Service, will become fully
vested, regardless of any vesting schedule which otherwise might apply.  If a
Participant separates from Service before satisfying the age requirement, but
after having satisfied the Service requirement, the Participant will be
entitled to elect an Early Retirement benefit upon satisfaction of the age
requirement.

6.3      BENEFITS ON TERMINATION OF EMPLOYMENT

(a)      If a Participant terminates employment prior to Normal Retirement Age,
         such Participant shall be entitled to receive the vested balance held
         in his or her account payable at Normal Retirement Age in the normal
         form, or if elected, in one of the optional forms of payment provided
         hereunder.  If applicable, the Early Retirement Benefit provisions may
         be elected.  Unless provided otherwise in the Adoption Agreement, a
         former Participant may make application to the Employer requesting
         early payment of any deferred vested and nonforfeitable benefit due.

(b)      If a Participant terminates employment, and the value of that
         Participant's vested account balance derived from Employer and
         Employee contributions is not greater than $3,500, the Participant
         will receive a lump sum distribution of the value of the entire vested
         portion of such account balance and the unvested portion will be
         treated as a forfeiture.  For purposes of this Article, if the value
         of a Participant's vested account balance is zero, the Participant
         shall be deemed to have received a distribution of such vested account
         balance.  For Plan Years beginning prior to 1989, a Participant's
<PAGE>   45

         Vested Account Balance shall not include Qualified Voluntary
         Contributions.  Notwithstanding the above, if the Employer maintains
         or has maintained a policy of not distributing any amounts until the
         Participant's Normal Retirement Age, the Employer can continue to
         uniformly apply such policy.

(c)      If a Participant terminates Service with a vested account balance
         derived from Employer and Employee contributions in excess of $3,500,
         and elects (with his or her Spouse's consent) to receive 100% of the
         value of his or her vested account balance in a lump sum, the
         non-vested portion will be treated as a forfeiture.  Except as
         provided at paragraph 6.4(c), the Participant (and his or her Spouse)
         must consent to any distribution, when the vested account balance
         described above exceeds $3,500 or if at the time of any prior
         distribution it exceeded $3,500.  For purposes of this paragraph, for
         Plan Years beginning prior to 1989, a Participant's Vested Account
         Balance shall not include Qualified Voluntary Contributions.

(d)      Distribution of less than 100% of the Participant's vested account
         balance shall only be permitted if the Participant is fully vested
         upon termination of employment.

(e)      If a Participant who is not 100% vested receives or is deemed to
         receive a distribution pursuant to subsection (a), (b) or (c) of this
         paragraph, and such Participant's non- vested benefit is forfeited
         hereunder, and if such Participant resumes employment covered under
         this Plan, the Participant shall have the right to repay to the Plan
         the full amount of the distribution attributable to Employer
         contributions on or before the earlier of the date that the
         Participant incurs 5 consecutive 1-year Breaks in Service following
         the date of distribution or five years after the first date on which
         the Participant is subsequently reemployed.  In such event, the
         Participant's forfeiture shall be restored to his or her account as of
         the Valuation Date at the end of the Plan Year following the date on
         which repayment of the distribution is received.  Restoration of the
         forfeiture amount shall be accomplished in accordance with the
         procedure selected by the Employer in the Adoption Agreement.

(f)      A Participant shall also have the option, to postpone payment of his
         or her Plan benefits until the first day of April following the
         calendar year in which he or she attains age 70-1/2.  Any balance of a
         Participant's account resulting from his or her Employee contributions
         not previously withdrawn, if any, may be withdrawn by the Participant
         immediately following separation from Service.

(g)      If a Participant ceases to be an active Employee as a result of a
         disability as defined at paragraph 1.16, such Participant shall be
         able to make an application for a disability retirement benefit
         payment.  The Participant's account balance will be deemed
         "immediately distributable" as set forth in paragraph 6.4, and will be
         fully vested pursuant to paragraph 9.2.

6.4      RESTRICTIONS ON IMMEDIATE DISTRIBUTIONS
<PAGE>   46

(a)      An account balance is immediately distributable if any part of the
         account balance could be distributed to the Participant (or Surviving
         Spouse) before the Participant attains (or would have attained if not
         deceased) the later of the Normal Retirement Age or age 62.

(b)      If the value of a Participant's vested account balance derived from
         Employer and Employee Contributions exceeds (or at the time of any
         prior distribution exceeded) $3,500, and the account balance is
         immediately distributable, the Participant and his or her Spouse (or
         where either the Participant or the Spouse has died, the survivor)
         must consent to any distribution of such account balance. The consent
         of the Participant and the Spouse shall be obtained in writing within
         the 90-day period ending on the annuity starting date, which is the
         first day of the first period for which an amount is paid as an
         annuity or any other form.  The Plan Administrator shall notify the
         Participant and the Participant's Spouse of the right to defer any
         distribution until the later of the date on which the Participant
         attains (or would have attained if not deceased) the Normal Retirement
         Age or age 62.  Such notification shall include a general description
         of the material features, and an explanation of the relative values of
         the optional forms of benefit available under the plan, in a manner
         that would satisfy the notice requirements of Code Section 417(a)(3),
         and shall be provided no less than 30 days and no more than 90 days
         prior to the annuity starting date.

(c)      Notwithstanding the foregoing, only the Participant need consent to
         the commencement of a distribution in the form of a Qualified Joint
         and Survivor Annuity while the account balance is immediately
         distributable.  Furthermore, if payment in the form of a Qualified
         Joint and Survivor Annuity is not required with respect to the
         Participant pursuant to paragraph 8.7 of the Plan, only the
         Participant need consent to the distribution of an account balance
         that is immediately distributable.  Neither the consent of the
         Participant nor the Participant's Spouse shall be required to the
         extent that a distribution is required to satisfy Code Section
         401(a)(9) or Code Section 415.  In addition, upon termination of this
         Plan, if the Plan does not offer an annuity option (purchased from a
         commercial provider), the Participant's account balance may, without
         the Participant's consent, be distributed to the Participant or
         transferred to another Defined Contribution Plan [other than an
         employee stock ownership plan as defined in Code Section 4975(e)(7)]
         within the same controlled group.

(d)      For purposes of determining the applicability of the foregoing consent
         requirements to distributions made before the first day of the first
         Plan Year beginning after 1988, the Participant's vested account
         balance shall not include amounts attributable to Qualified Voluntary
         Contributions.

6.5      NORMAL FORM OF PAYMENT  The normal form of payment for a
profit-sharing plan satisfying the requirements of paragraph 8.7 hereof shall
be a lump sum with no option for annuity payments.  For all other plans, the
normal form of payment hereunder shall be a Qualified Joint and Survivor
Annuity as provided under Article VIII.  A Participant whose vested account
balance derived from Employer and Employee contributions
<PAGE>   47

exceed $3,500, or if at the time of any prior distribution it exceeded $3,500,
shall (with the consent of his or her Spouse) have the right to receive his or
her benefit in a lump sum or in monthly, quarterly, semi-annual or annual
payments from the Fund over any period not extending beyond the life expectancy
of the Participant and his or her Beneficiary.  For purposes of this paragraph,
for Plan Years beginning prior to 1989, a Participant's Vested Account Balance
shall not include Qualified Voluntary Contributions.  The normal form of
payment shall be automatic, unless the Participant files a written request with
the Employer prior to the date on which the benefit is automatically payable,
electing a lump sum or installment payment option. No amendment to the Plan may
eliminate one of the optional distribution forms listed above.

6.6      COMMENCEMENT OF BENEFITS

(a)      Unless the Participant elects otherwise, distribution of benefits will
         begin no later than the 60th day after the close of the Plan Year in
         which the latest of the following events occurs:

         (1)     the Participant attains age 65 (or normal retirement age if
                 earlier),

         (2)     the 10th anniversary of the year in which the Participant
                 commenced participation in the Plan, or

         (3)     the Participant terminates Service with the Employer.

(b)      Notwithstanding the foregoing, the failure of a Participant and Spouse
         (if necessary) to consent to a distribution while a benefit is
         immediately distributable, within the meaning of paragraph 6.4 hereof,
         shall be deemed an election to defer commencement of payment of any
         benefit sufficient to satisfy this paragraph.

(c)      Unless the Employer provides otherwise in the Adoption Agreement,
         distributions of benefits will be made within 60 days following the
         close of the Plan Year during which a distribution is requested or
         otherwise becomes payable.

6.7      CLAIMS PROCEDURES  Upon retirement, death, or other severance of
employment, the Participant or his or her representative may make application
to the Employer requesting payment of benefits due and the manner of payment.
If no application for benefits is made, the Employer shall automatically pay
any vested benefit due hereunder in the normal form at the time prescribed at
paragraph 6.5.  If an application for benefits is made, the Employer shall
accept, reject, or modify such request and shall notify the Participant in
writing setting forth the response of the Employer and in the case of a denial
or modification the Employer shall:

(a)      state the specific reason or reasons for the denial,

(b)      provide specific reference to pertinent Plan provisions on which the
         denial is based,

(c)      provide a description of any additional material or information
         necessary for the Participant or his representative to perfect the
<PAGE>   48

         claim and an explanation of why such material or information is
         necessary, and 

(d)      explain the Plan's claim review procedure as contained in this
         paragraph.

In the event the request is rejected or modified, the Participant or his or her
representative may within 60 days following receipt by the Participant or
representative of such rejection or modification, submit a written request for
review by the Employer of its initial decision.  Within 60 days following such
request for review, the Employer shall render its final decision in writing to
the Participant or representative stating specific reasons for such decision.
If the Participant or representative is not satisfied with the Employer's final
decision, the Participant or representative can institute an action in a
federal court of competent jurisdiction; for this purpose, process would be
served on the Employer.

6.8      IN-SERVICE WITHDRAWALS  An Employee may withdraw all or any part of
the fair market value of his or her Mandatory Contributions, Voluntary
Contributions, Qualified Voluntary Contributions or Rollover Contributions,
upon written request to the Employer.  Transfer Contributions, which originate
from a Plan meeting the safe-harbor provisions of paragraph 8.7, may also be
withdrawn, by an Employee, upon written request to the Employer.  Transfer
Contributions which originate from a Plan not meeting the safe-harbor
provisions may only be withdrawn upon retirement,death,disability, termination
or termination of the Plan, and will be subject to Spousal consent requirements
contained in Code Sections 411(a)(11) and 417.  Such request shall include the
Participant's address, social security number birth date, and amount of the
withdrawal.  If at the time a distribution of Qualified Voluntary Contributions
is received the Participant has not attained age 59-1/2 and is not disabled, as
defined at Code Section 22(e)(3), the Participant will be subject to a federal
income tax penalty, unless the distribution is rolled over to a qualified plan
or individual retirement plan within 60 days of the date of distribution.  A
Participant may withdraw all or any part of the fair market value of his or her
pre- 1987 Voluntary Contributions with or without withdrawing the earnings
attributable thereto.  Post-1986 Voluntary Contributions may only be withdrawn
along with a portion of the earnings thereon.  The amount of the earnings to be
withdrawn is determined by using the formula: DA[1-(V / V + E)], where DA is
the distribution amount, V is the amount of Voluntary Contributions and V + E
is the amount of Voluntary Contributions plus the earnings attributable
thereto.  A Participant withdrawing his or her other contributions prior to
attaining age 59-1/2, will be subject to a federal tax penalty to the extent
that the withdrawn amounts are includible in income.  Unless the Employer
provides otherwise in the Adoption Agreement, any Participant in a
profit-sharing plan who is 100% fully vested in his or her Employer
contributions may withdraw all or any part of the fair market value of any of
such contributions that have been in the account at least two years, plus the
investment earnings thereon, without separation from Service.  Such
distributions shall not be eligible for redeposit to the Fund.  A withdrawal
under this paragraph shall not prohibit such Participant from sharing in any
future Employer Contribution he or she would otherwise be eligible to share in.
A request to withdraw amounts pursuant to this paragraph must if applicable, be
consented to by
<PAGE>   49

the Participant's Spouse.  The consent shall comply with the requirements of
paragraph 6.4 relating to immediate distributions.

6.9      HARDSHIP WITHDRAWAL  If permitted by the Trustee/Custodian and the
Employer in the Adoption Agreement, a Participant in a profit-sharing plan may
request a hardship withdrawal prior to attaining age 59-1/2.  If the
Participant has not attained age 59-1/2, the Participant may be subject to a
federal income tax penalty.  Such request shall be in writing to the Employer
who shall have sole authority to authorize a hardship withdrawal, pursuant to
the rules below.  Hardship withdrawals are subject to the Spousal consent
requirements contained in Code Sections 411(a)(11) and 417.  Only the following
reasons are valid to obtain hardship withdrawal:

(a)      medical expenses [within the meaning of Code Section 213(d)] of the
         Participant, his or her Spouse, children and other dependents,

(b)      the purchase (excluding mortgage payments) of the principal residence
         for the Participant,

(c)      payment of tuition and related educational expenses for the next
         twelve (12) months of post-secondary education for the Participant,
         his or her Spouse, children or other dependents, or

(d)      the need to prevent eviction of the Employee from or a foreclosure on
         the mortgage of, the Employee's principal residence.

Furthermore, the distribution may not be in excess of the amount of the
immediate and heavy financial need [(a) through (d)] above.  The Participant
must certify that other assets are not available to meet the hardship.

If a distribution is made at a time when a Participant has a nonforfeitable
right to less than 100% of the account balance derived from Employer
contributions and the Participant may, by virtue of continuing Service,
increase the nonforfeitable percentage in the account:

(a)      a separate account will be established for the Participant's interest
         in the Plan as of the time of the distribution, and

(b)      at any relevant time the Participant's nonforfeitable portion of the
         separate account will be equal to an amount ("X") determined by the
         formula:

                         X = P [AB + (R X D)] - (R X D)

For purposes of applying the formula: "P" is the nonforfeitable percentage at
the relevant time, "AB" is the account balance at the relevant time, "D" is the
amount of the distribution and "R" is the ratio of the account balance at the
relevant time to the account balance after distribution.


                                  ARTICLE VII

                           DISTRIBUTION REQUIREMENTS
<PAGE>   50

7.1      JOINT AND SURVIVOR ANNUITY REQUIREMENTS  All distributions made under
the terms of this Plan must comply with the provisions of Article VIII
including, if applicable, the safe harbor provisions thereunder.

7.2      MINIMUM DISTRIBUTION REQUIREMENTS  All distributions required under
this Article shall be determined and made in accordance with the minimum
distribution requirements of Code Section 401 (a)(9) and the regulations
thereunder, including the minimum distribution incidental benefit rules found
at Section 1.401 (a)(9)-2 of the Regulations.  The entire interest of a
Participant must be distributed, or begin to be distributed, no later than the
Participant's Required Beginning Date.  Life expectancy and joint and last
survivor life expectancy are computed by using the expected return multiples
found in Tables V and VI of Section 1.72-9 of the Income Tax Regulations.

7.3      LIMITS ON DISTRIBUTION PERIODS  As of the First Distribution Calendar
Year, distributions, if not made in a single-sum, may only be made over one of
the following periods (or a combination thereof):

(a)      the life of the Participant,

(b)      the life of the Participant and a Designated Beneficiary,

(c)      a period certain not extending beyond the life expectancy of the
         Participant, or

(d)      a period certain not extending beyond the joint and last survivor
         expectancy of the Participant and a Designated Beneficiary.

7.4      REQUIRED DISTRIBUTIONS ON OR AFTER THE REQUIRED BEGINNING DATE

(a)      If a participant's account balance is to be distributed over (1) a
         period not extending beyond the life expectancy of the Participant or
         the joint life and last survivor expectancy of the Participant and the
         Participant's Designated Beneficiary or (2) a period not extending
         beyond the life expectancy of the Designated Beneficiary, the amount
         required to be distributed for each calendar year, beginning with
         distributions for the First Distribution Calendar Year, must at least
         equal the quotient obtained by dividing the Participant's account
         balance by the Applicable Life Expectancy.

(b)      For calendar years beginning before 1989, if the Participant's Spouse
         is not the Designated Beneficiary, the method of distribution selected
         must have required that at least 50% of the Present Value of the
         amount available for distribution was to be paid within the life
         expectancy of the Participant.

(c)      For calendar years beginning after 1988, the amount to be distributed
         each year, beginning with distributions for the First Distribution
         Calendar Year shall not be less than the quotient obtained by dividing
         the Participant's benefit by the lesser of (1) the Applicable Life
         Expectancy or (2) if the Participant's Spouse is not the Designated
         Beneficiary, the applicable divisor determined from the table set
         forth in Q&A-4 of Section 1.401(a)(9)-2 of the Income Tax Regulations.
         Distributions after the death of the Participant shall be distributed
<PAGE>   51

         using the Applicable Life Expectancy as the relevant divisor without
         regard to Regulations Section 1.401 (a)(9)-2.

(d)      The minimum distribution required for the Participant's First
         Distribution Calendar Year must be made on or before the Participant's
         Required Beginning Date.  The minimum distribution for other calendar
         years, including the minimum distribution for the Distribution
         Calendar Year in which the Participant's Required Beginning Date
         occurs, must be made on or before December 31 of that Distribution
         Calendar Year.

(e)      If the Participant's benefit is distributed in the form of an annuity
         purchased from an insurance company, distributions thereunder shall be
         made in accordance with the requirements of Code Section 401(a)(9) and
         the Regulations thereunder.

(f)      For purposes of determining the amount of the required distribution
         for each Distribution Calendar Year, the account balance to be used is
         the account balance determined as of the last valuation preceding the
         Distribution Calendar Year.  This balance will be increased by the
         amount of any contributions or forfeitures allocated to the account
         balance after the valuation date in such preceding calendar year.
         Such balance will also be decreased by distributions made after the
         Valuation Date in such preceding Calendar Year.

(g)      For purposes of subparagraph 7.4(f), if any portion of the minimum
         distribution for the First Distribution Calendar Year is made in the
         second Distribution Calendar Year on or before the Required Beginning
         Date, the amount of the minimum distribution made in the second
         Distribution Calendar Year shall be treated as if it had been made in
         the immediately preceding Distribution Calendar Year.

7.5      REQUIRED BEGINNING DATE

(a)      General Rule.  The Required Beginning Date of a Participant is the
         first day of April of the calendar year following the calendar year in
         which the Participant attains age 70-1/2.

(b)      Transitional Rules.  The Required Beginning Date of a Participant who
         attained age 70-1/2 before 1988, shall be determined in accordance
         with (1) or (2) below:

         (1)     Non-5-percent owners.  The Required Beginning Date of a
                 Participant who is not a 5-percent owner is the first day of
                 April of the calendar year following the calendar year in
                 which the later of retirement or attainment of age 70-1/2
                 occurs.  In the case of a Participant who is not a 5-percent
                 owner who attains age 70- 1/2 during 1988 and who has not
                 retired as of January 1, 1989, the Required Beginning Date is
                 April 1, 1990.

         (2)     5-percent owners.  The Required Beginning Date of a
                 Participant who is a 5-percent owner during any year beginning
                 after 1979, is the first day of April following the later of:
<PAGE>   52

                  (i)     the calendar year in which the Participant attains age
                          70-1/2, or 

                 (ii)     the earlier of the calendar year with or within which
                          ends the plan year in which the Participant becomes a
                          5- percent owner, or the calendar year in which the
                          Participant retires.

(c)      A Participant is treated as a 5-percent owner for purposes of this
         Paragraph if such Participant is a 5-percent owner as defined in Code
         Section 416(i) (determined in accordance with Section 416 but without
         regard to whether the Plan is Top-Heavy) at any time during the Plan
         Year ending with or within the calendar year in which such Owner
         attains age 66-1/2 or any subsequent Plan Year.

(d)      Once distributions have begun to a 5-percent owner under this
         paragraph, they must continue to be distributed, even if the
         Participant ceases to be a 5-percent owner in a subsequent year.

7.6      TRANSITIONAL RULE

(a)      Notwithstanding the other requirements of this Article and subject to
         the requirements of Article VIII, Joint and Survivor Annuity
         Requirements, distribution on behalf of any Employee, including a
         5-percent owner, may be made in accordance with all of the following
         requirements (regardless of when such distribution commences):

                 (i)      The distribution by the Trust is one which would not
                          have disqualified such Trust under Code Section 401
                          (a)(9) as in effect prior to amendment by the Deficit
                          Reduction Act of 1984.

                 (ii)     The distribution is in accordance with a method of
                          distribution designated by the Employee whose
                          interest in the Trust is being distributed or, if the
                          Employee is deceased, by a beneficiary of such
                          Employee.

                (iii)     Such designation was in writing, was signed by the
                          Employee or the beneficiary, and was made before 1984.

                 (iv)     The Employee had accrued a benefit under the Plan as
                          of December 31, 1983.

                  (v)     The method of distribution designated by the Employee
                          or the beneficiary specifies the time at which
                          distribution will commence, the period over which
                          distributions will be made, and in the case of any
                          distribution upon the Employee's death, the
                          beneficiaries of the Employee listed in order of
                          priority.

(b)      A distribution upon death will not be covered by this transitional
         rule unless the information in the designation contains the required
         information described above with respect to the distributions to be
         made upon the death of the Employee.
<PAGE>   53

(c)      For any distribution which commences before 1984, but continues after
         1983, the Employee, or the beneficiary, to whom such distribution is
         being made, will be presumed to have designated the method of
         distribution under which the distribution is being made if the method
         of distribution was specified in writing and the distribution
         satisfies the requirements in subparagraphs (a)(i) and (v) above.

(d)      If a designation is revoked, any subsequent distribution must satisfy
         the requirements of Code Section 401(a)(9) and the regulations
         thereunder.  If a designation is revoked subsequent to the date
         distributions are required to begin, the Trust must distribute by the
         end of the calendar year following the calendar year in which the
         revocation occurs the total amount not yet distributed which would
         have been required to have been distributed to satisfy Code Section
         401(a)(9) and the regulations thereunder, but for the section
         242(b)(2) election of the Tax Equity and Fiscal Responsibility Act of
         1982.  For calendar years beginning after 1988, such distributions
         must meet the minimum distribution incidental benefit requirements in
         section 1.401 (a)(9)-2 of the Income Tax Regulations.  Any changes in
         the designation will be considered to be a revocation of the
         designation.  However, the mere substitution or addition of another
         beneficiary (one not named in the designation) under the designation
         will not be considered to be a revocation of the designation, so long
         as such substitution or addition does not alter the period over which
         distributions are to be made under the designation, directly or
         indirectly (for example, by altering the relevant measuring life).  In
         the case in which an amount is transferred or rolled over from one
         plan to another plan, the rules in Q&A J-2 and Q&A J- 3 of the
         regulations shall apply.

7.7      DESIGNATION OF BENEFICIARY FOR DEATH BENEFIT  Each Participant shall
file a written designation of beneficiary with the Employer upon qualifying for
participation under this Plan.  Such designation shall remain in force until
revoked by the Participant by filing a new beneficiary form with the Employer.
The Participant may elect to have a portion of his or her account balance
invested in an insurance contract.  If an insurance contract is purchased under
the Plan the Trustee must be named as Beneficiary under the terms of the
contract.  However, the Participant shall designate a Beneficiary to receive
the proceeds of the contract after settlement is received by the Trustee.
Under a profit-sharing plan satisfying the requirements of paragraph 8.7, the
Designated Beneficiary shall be the Participant's Surviving Spouse, if any,
unless such Spouse properly consents otherwise.

7.8      NONEXISTENCE OF BENEFICIARY  Any portion of the amount payable
hereunder which is undisposed of because of the Participant's or former
Participant's failure to designate a Beneficiary, or because all of the
Designated Beneficiaries predeceased the Participant, shall be paid to his or
her Spouse.  If the Participant has no Spouse at the time of death, payment
shall be made to the personal representative of his or her estate in a lump
sum.

7.9      DISTRIBUTION BEGINNING BEFORE DEATH  If the Participant dies after
distribution of his or her interest has begun, the remaining portion of
<PAGE>   54

such interest will continue to be distributed at least as rapidly as under the
method of distribution being used prior to the Participant's death.

7.10     DISTRIBUTION BEGINNING AFTER DEATH  If the Participant dies before
distribution of his or her interest begins, distribution of the Participant's
entire interest shall be completed by December 31 of the calendar year
containing the fifth anniversary of the Participant's death except to the
extent that an election is made to receive distributions in accordance with (a)
or (b) below:

(a)      if any portion of the Participant's interest is payable to a
         Designated Beneficiary, distributions may be made over the life or
         over a period certain not greater than the life expectancy of the
         Designated Beneficiary commencing on or before December 31 of the
         calendar year immediately following the calendar year in which the
         Participant died;

(b)      if the Designated Beneficiary is the Participant's surviving Spouse,
         the date distributions are required to begin in accordance with (a)
         above shall not be earlier than the later of (1) December 31 of the
         calendar year immediately following the calendar year in which the
         participant died or (2) December 31 of the calendar year in which the
         Participant would have attained age 70-1/2.

If the Participant has not made an election pursuant to this paragraph 7.10 by
the time of his or her death, the Participant's Designated Beneficiary must
elect the method of distribution no later than the earlier of (1) December 31
of the calendar year in which distributions would be required to begin under
this section, or (2) December 31 of the calendar year which contains the fifth
anniversary of the date of death of the participant.  If the Participant has no
Designated Beneficiary, or if the Designated Beneficiary does not elect a
method of distribution, then distribution of the Participant's entire interest
must be completed by December 31 of the calendar year containing the fifth
anniversary of the Participant's death.

For purposes of this paragraph, if the Surviving Spouse dies after the
Participant, but before payments to such Spouse begin, the provisions of this
paragraph with the exception of paragraph (b) herein, shall be applied as if
the Surviving Spouse were the Participant.  For the purposes of this paragraph
and paragraph 7.9 distribution of a Participant's interest is considered to
begin on the Participant's Required Beginning Date (or, if the preceding
sentence is applicable, the date distribution is required to begin to the
Surviving Spouse).  If distribution in the form of an annuity described in
paragraph 7.4(e) irrevocably commences to the Participant before the Required
Beginning Date, the date distribution is considered to begin is the date
distribution actually commences.

For purposes of paragraph 7.9 and this paragraph, any amount paid to a child of
the Participant will be treated as if it had been paid to the Surviving Spouse
if the amount becomes payable to the Surviving Spouse when the child reaches
the age of majority.

7.11     ESCHEAT  In the event any vested account balance is unclaimed and the
Plan Administrator is unable to determine the whereabouts of the Participant,
beneficiary or any other person whose benefits from the Plan
<PAGE>   55

are due, within three years from the date such benefit would otherwise be
payable, such vested account balance shall be forfeited and revert to and
become part of the Trust upon written direction of the Plan Administrator;
provided, however, such unclaimed benefits shall be reinstated from earnings
and forfeitures, and Employer Contributions designated for that purpose if the
claimant to whom such benefit is due and owing subsequently makes written
application to the Plan Administrator.  The Plan Administrator also reserves
the right, with the consent of the Trustee/Custodian, to direct the
Trustee/Custodian to dispose of any unclaimed benefits under the escheat
statutes of the applicable state law, as defined in Article XVI.

                                  ARTICLE VIII

                    JOINT AND SURVIVOR ANNUITY REQUIREMENTS


8.1      APPLICABILITY OF PROVISIONS  The provisions of this Article shall
apply to any Participant who is credited with at least one Hour of Service with
the Employer on or after August 23,1984 and such other Participants as provided
in paragraph 8.8.

8.2      PAYMENT OF QUALIFIED JOINT AND SURVIVOR ANNUITY Unless an optional
form of benefit is selected pursuant to a Qualified Election within the 90 day
period ending on the Annuity Starting Date, a married Participant's Vested
Account Balance will be paid in the form of a Qualified Joint and Survivor
Annuity and an unmarried Participant's Vested Account Balance will be paid in
the form of a life annuity.  The Participant may elect to have such annuity
distributed upon attainment of the Early Retirement Age under the Plan.

8.3      PAYMENT OF QUALIFIED PRE-RETIREMENT SURVIVOR ANNUITY  Unless an
optional form of benefit has been selected within the Election Period pursuant
to a Qualified Election, if a Participant dies before benefits have commenced
then the Participant's vested account balance shall be paid to the Surviving
Spouse in the form of a life annuity.  The Surviving Spouse may elect to have
such annuity distributed within a reasonable period after the Participant's
death.

A Participant who does not meet the age 35 requirement set forth in the
Election Period as of the end of any current Plan Year may make a special
qualified election to waive the qualified Pre-retirement Survivor Annuity for
the period beginning on the date of such election and ending on the first day
of the Plan Year in which the Participant will attain age 35.  Such election
shall not be valid unless the Participant receives a written explanation of the
Qualified Pre-retirement Survivor Annuity in such terms as are comparable to
the explanation required under paragraph 8.4.  Qualified Pre-retirement
Survivor Annuity coverage will be automatically reinstated as of the first day
of the Plan Year in which the Participant attains age 35.  Any new waiver on or
after such date shall be subject to the full requirements of this Article.

8.4      QUALIFIED ELECTION  A Qualified Election is an election to either
waive a Qualified Joint and Survivor Annuity or a qualified pre-retirement
survivor annuity.  Any such election shall not be effective unless:
<PAGE>   56


(a)      the Participant's Spouse consents in writing to the election;

(b)      the election designates a specific Beneficiary, including any class of
         beneficiaries or any contingent beneficiaries, which may not be
         changed without spousal consent (or the Spouse expressly permits
         designations by the Participant without any further spousal consent);

(c)      the Spouse's consent acknowledges the effect of the election; and

(d)      the Spouse's consent is witnessed by a Plan representative or notary
         public.

Additionally, a Participant's waiver of the Qualified Joint and Survivor
Annuity shall not be effective unless the election designates a form of benefit
payment which may not be changed without spousal consent (or the Spouse
expressly permits designations by the Participant without any further spousal
consent).  If it is established to the satisfaction of the Plan Administrator
that there is no Spouse or that the Spouse cannot be located, a waiver will be
deemed a Qualified Election.  Any consent by a Spouse obtained under this
provision (or establishment that the consent of a Spouse may not be obtained)
shall be effective only with respect to such Spouse.  A consent that permits
designations by the Participant without any requirement of further consent by
such Spouse must acknowledge that the Spouse has the right to limit consent to
a specific beneficiary, and a specific form of benefit where applicable, and
that the Spouse voluntarily elects to relinquish either or both of such rights.
A revocation of a prior waiver may be made by a Participant without the consent
of the Spouse at any time before the commencement of benefits.  The number of
revocations shall not be limited.  No consent obtained under this provision
shall be valid unless the Participant has received notice as provided in
paragraphs 8.5 and 8.6 below.

8.5      NOTICE REQUIREMENTS FOR QUALIFIED JOINT AND SURVIVOR ANNUITY The Plan
Administrator shall provide each Participant a written explanation of:

(a)      the terms and conditions of a Qualified Joint and Survivor Annuity;

(b)      the Participant's right to make and the effect of an election to waive
the Qualified Joint and Survivor Annuity form of benefit;

(c)      the rights of a Participant's Spouse; and

(d)      the right to make, and the effect of, a revocation of a previous
election to waive the Qualified Joint and Survivor Annuity.

Such notice shall be provided not less than 30 days and no more than 90 days
prior to the Annuity Starting date.

8.6      NOTICE REQUIREMENTS FOR QUALIFIED PRE-RETIREMENT SURVIVOR ANNUITY  The
Plan Administrator shall provide each Participant a written explanation of the
qualified pre-retirement survivor annuity in such terms and in such manner as
would be comparable to the explanation provided for meeting the requirements of
paragraph 8.5 applicable to a Qualified Joint and Survivor Annuity.  Such
explanation shall be provided within whichever of the following periods ends
last:
<PAGE>   57


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

(b)      a reasonable period ending after the individual becomes a Participant;

(c)      a reasonable period ending after this Article first applies to the
         Participant.  Notwithstanding the foregoing, notice must be provided
         within a reasonable period ending after separation from Service in the
         case of a Participant who separates from Service before attaining age
         35.

For purposes of applying the preceding paragraph, a reasonable period ending
after the events described in (b) and (c) is the end of the two-year period
beginning one-year prior to the date the applicable event occurs, and ending
one-year after that date.  In the case of a Participant who separates from
Service before the Plan Year in which age 35 is attained, notice shall be
provided within the two-year period beginning one year prior to separation and
ending one year after separation.  If such a Participant subsequently returns
to employment with the Employer, the applicable period for such Participant
shall be re-determined.

8.7      SPECIAL SAFE-HARBOR EXCEPTION FOR CERTAIN PROFIT-SHARING PLANS

(a)      This paragraph shall apply to a Participant in a profit- sharing plan,
         and to any distribution made on or after the first day of the first
         plan year beginning after 1988, from or under a separate account
         attributable solely to Qualified Voluntary contributions, as
         maintained on behalf of a Participant in a money purchase pension
         plan, (including a target benefit plan) if the following conditions
         are satisfied:

         (1)     the Participant does not or cannot elect payments in the form
                 of a life annuity; and

         (2)     on the death of a Participant, the Participant's Vested
                 Account Balance will be paid to the Participant's Surviving
                 Spouse, but if there is no Surviving Spouse, or if the
                 Surviving Spouse has consented in a manner conforming to a
                 Qualified Election, then to the Participant's Designated
                 Beneficiary.

         The Surviving Spouse may elect to have distribution of the Vested
         Account Balance commence within the 90-day period following the date
         of the Participant's death.  The account balance shall be adjusted for
         gains or losses occurring after the Participant's death in accordance
         with the provisions of the Plan governing the adjustment of account
         balances for other types of distributions.  These safe-harbor rules
         shall not be operative with respect to a Participant in a
         profit-sharing plan if that plan is a direct or indirect transferee of
         a Defined Benefit Plan, money purchase pension plan, a target benefit
         plan, stock bonus plan, or profit-sharing plan which is subject to the
         survivor annuity requirements of Code Section 401(a)(11) and Code
         Section 417, and would therefore have a Qualified Joint and Survivor
         Annuity as its normal form of benefit.
<PAGE>   58

(b)      The Participant may waive the spousal death benefit described in this
         paragraph at any time provided that no such waiver shall be effective
         unless it satisfies the conditions (described in paragraph 8.4) that
         would apply to the Participant's waiver of the qualified
         pre-retirement survivor annuity.

(c)      If this paragraph 8.7 is operative, then all other provisions of this
         Article other than paragraph 8.8 are inoperative.

8.8      TRANSITIONAL JOINT AND SURVIVOR ANNUITY RULES  Special transition
rules apply to Participants who are not receiving benefits on August 23, 1984.

(a)      Any living Participant not receiving benefits on August 23, 1984, who
         would otherwise not receive the benefits prescribed by the previous
         paragraphs of this Article, must be given the opportunity to elect to
         have the prior paragraphs of this Article apply if such Participant is
         credited with at least one Hour of Service under this Plan or a
         predecessor Plan in a Plan Year beginning on or after January 1, 1976
         and such Participant had at least 10 Years of Service for vesting
         purposes when he or she separated from Service.

(b)      Any living Participant not receiving benefits on August 23, 1984, who
         was credited with at least one Hour of Service under this Plan or a
         predecessor Plan on or after September 2,1974, and who is not
         otherwise credited with any Service in a Plan Year beginning on or
         after January 1, 1976, must be given the opportunity to have his or
         her benefits paid in accordance with paragraph 8.9.

(c)      The respective opportunities to elect [as described in (a) and (b)
         above] must be afforded to the appropriate Participants during the
         period commencing on August 23, 1984 and ending on the date benefits
         would otherwise commence to said Participants.

8.9      AUTOMATIC JOINT AND SURVIVOR ANNUITY AND EARLY SURVIVOR ANNUITY  Any
Participant who has elected pursuant to paragraph 8.8(b) and any Participant
who does not elect under paragraph 8.8(a) or who meets the requirements of
paragraph 8.8(a), except that such Participant does not have at least 10 years
of vesting Service when he or she separates from Service, shall have his or her
benefits distributed in accordance with all of the following requirements if
benefits would have been payable in the form of a life annuity.

(a)      Automatic Joint and Survivor Annuity.  If benefits in the form of a
         life annuity become payable to a married Participant who:

         (1)     begins to receive payments under the Plan on or after Normal
                 Retirement Age, or

         (2)     dies on or after Normal Retirement Age while still working for
                 the Employer, or

         (3)     begins to receive payments on or after the Qualified Early
                 Retirement Age, or
<PAGE>   59

         (4)     separates from Service on or after attaining Normal Retirement
                 (or the Qualified Early Retirement Age) and after satisfying
                 the eligibility requirements for the payment of benefits under
                 the Plan and thereafter dies before beginning to receive such
                 benefits, then such benefits will be received under this Plan
                 in the form of a Qualified Joint and Survivor Annuity, unless
                 the Participant has elected otherwise during the Election
                 Period.  The Election Period must begin at least 6 months
                 before the Participant attains Qualified Early Retirement Age
                 and end not more than 90 days before the commencement of
                 benefits.  Any election hereunder will be in writing and may
                 be changed by the Participant at any time.

(b)      Election of Early Survivor Annuity.   A Participant who is employed
         after attaining the Qualified Early Retirement Age will be given the
         opportunity to elect, during the Election Period, to have a survivor
         annuity payable on death.  If the Participant elects the survivor
         annuity, payments under such annuity must not be less than the
         payments which would have been made to the Spouse under the Qualified
         Joint and Survivor Annuity if the Participant had retired on the day
         before his or her death.  Any election under this provision will be in
         writing and may be changed by the Participant at any time.  The
         Election Period begins on the later of:

         (1)     the 90th day before the Participant attains the Qualified Early
                 Retirement Age, or

         (2)     the date on which participation begins, and ends on the date
                 the Participant terminates employment.

8.10     ANNUITY CONTRACTS  Any annuity contract distributed herefrom must be
nontransferable.  The terms of any annuity contract purchased and distributed
by the Plan to a Participant or Spouse shall comply with the requirements of
this Plan.


                                   ARTICLE IX

                                    VESTING

9.1      EMPLOYEE CONTRIBUTIONS  A Participant shall always have a 100% vested
and nonforfeitable interest in his or her Mandatory Contributions, Voluntary
Contributions, Qualified Voluntary Contributions, Rollover Contributions, and
Transfer Contributions plus the earnings thereon.  No forfeiture of Employer
related contributions (including any minimum contributions made under paragraph
14.2 hereof) will occur solely as a result of an Employee's withdrawal of any
Employee contributions.

9.2      EMPLOYER CONTRIBUTIONS  A Participant shall acquire a vested and
nonforfeitable interest in his or her account attributable to Employer
contributions in accordance with the table selected in the Adoption Agreement,
provided that if a Participant is not already fully vested, he or she shall
become so upon attaining Normal Retirement Age, Early Retirement Age, on death
prior to normal retirement, on retirement due to Disability, or on termination
of the Plan.
<PAGE>   60


9.3      COMPUTATION PERIOD  The computation period for purposes of determining
Years of Service and Breaks in Service for purposes of computing a
Participant's nonforfeitable right to his or her account balance derived from
Employer contributions shall be determined by the Employer in the Adoption
Agreement.  If the Employer provides for other than full and immediate vesting
and does not designate otherwise, the computation period shall be the Plan
Year.  In the event a former Participant with no vested interest in his or her
Employer contribution account requalifies for participation in the Plan after
incurring a Break in Service, such Participant shall be credited for vesting
with all pre-break and post-break Service.

9.4      REQUALIFICATION PRIOR TO FIVE CONSECUTIVE ONE-YEAR BREAKS IN SERVICE
The account balance of such Participant shall consist of any undistributed
amount in his or her account as of the date of re-employment plus any future
contributions added to such account plus the investment earnings on the
account.  The vested account balance of such Participant shall be determined by
multiplying the Participant's account balance (adjusted to include any
distribution or redeposit made under paragraph 6.3 hereof) by such
Participant's vested percentage.

All Service of the Participant, both prior to and following the break, shall be
counted when computing the Participant's vested percentage.

9.5      REQUALIFICATION AFTER FIVE CONSECUTIVE ONE-YEAR BREAKS IN SERVICE  If
such Participant is not fully vested upon re-employment, a new account shall be
established for such Participant to separate his or her deferred vested and
nonforfeitable account, if any, from the account to which new allocations will
be made.  The Participant's deferred account to the extent remaining shall be
fully vested and shall continue to share in earnings and losses of the Fund.
When computing the Participant's vested portion of the new account, all
pre-break and post-break Service shall be counted.  However, notwithstanding
this provision, no such former Participant who has had five consecutive
one-year Breaks in Service shall acquire a larger vested and nonforfeitable
interest in his or her prior account balance as a result of requalification
hereunder.

9.6      CALCULATING VESTED INTEREST  A Participant's vested and nonforfeitable
interest shall be calculated by multiplying the fair market value of his or her
account attributable to Employer contributions on the Valuation Date preceding
distribution by the decimal equivalent of the vested percentage as of his or
her termination date.  The amount attributable to Employer contributions for
purposes of the calculation includes amounts previously paid out pursuant to
paragraph 6.3 and not repaid.  The Participant's vested and nonforfeitable
interest, once calculated above, shall be reduced to reflect those amounts
previously paid out and not repaid.  The Participant's vested and
nonforfeitable interest so determined shall continue to share in the investment
earnings and any increase or decrease in the fair market value of the Fund up
to the Valuation Date preceding or coinciding with payment.

9.7      FORFEITURES  Any balance in the account of a Participant who has
separated from Service to which he or she is not entitled under the foregoing
provisions, shall be forfeited and applied as provided in the Adoption
Agreement.  If not specified otherwise in the Adoption Agreement,
<PAGE>   61

forfeitures will be allocated to Participants in the same manner as the
Employer's contribution.  A forfeiture may only occur if the Participant has
received a distribution from the Plan or if the Participant has incurred five
consecutive l-year Breaks in Service.  Forfeitures shall inure only to the
accounts of Participants of the adopting Employer's plan.  If not specified
otherwise in the Adoption Agreement, forfeitures shall be allocated at the end
of the Plan Year during which the former Participant incurs five consecutive
one-year Breaks in Service.

9.8      AMENDMENT OF VESTING SCHEDULE  No amendment to the Plan shall have the
effect of decreasing a Participant's vested interest determined without regard
to such amendment as of the later of the date such amendment is adopted or the
date it becomes effective.  Further, if the vesting schedule of the Plan is
amended, or the Plan is amended in any way that directly or indirectly affects
the computation of any Participant's nonforfeitable percentage, or if the Plan
is deemed amended by an automatic change to or from a Top-Heavy vesting
schedule, each Participant with at least three Years of Service with the
Employer may elect, within a reasonable period after the adoption of the
amendment or change, to have his or her nonforfeitable percentage computed
under the Plan without regard to such amendment or change.  For Participants
who do not have at least one hour of service in any Plan Year beginning after
1988, the preceding sentence shall be applied by substituting "Five Years of
Service" for "Three Years of Service" where such language appears.  The period
during which the election may be made shall commence with the date the
amendment is adopted or deemed to be made and shall end on the later of:

(a)      60 days after the amendment is adopted;

(b)      60 days after the amendment becomes effective; or

(c)      60 days after the Participant is issued written notice of the
         amendment by the Employer or the Trustee/Custodian.  If the
         Trustee/Custodian is asked to so notify, the Fund will be charged for
         the costs thereof.

No amendment to the Plan shall be effective to the extent that it has the
effect of decreasing a Participant's accrued benefit.  Notwithstanding the
preceding sentence, a Participant's account balance may be reduced to the
extent permitted under section 412(c)(8) of the Code (relating to financial
hardships).  For purposes of this paragraph, a Plan amendment which has the
effect of decreasing a Participant's account balance or eliminating an optional
form of benefit, with respect to benefits attributable to service before the
amendment shall be treated as reducing an accrued benefit.

9.9      SERVICE WITH CONTROLLED GROUPS  All Years of Service with other
members of a controlled group of corporations [as defined in Code Section
414(b)], trades or businesses under common control [as defined in Code Section
414(c)], or members of an affiliated service group [as defined in Code Section
414(m)] shall be considered for purposes of determining a Participant's
nonforfeitable percentage.

<PAGE>   62

                           LIMITATIONS ON ALLOCATIONS


10.1     PARTICIPATION IN THIS PLAN ONLY  If the Participant does not
participate in, and has never participated in another qualified plan, a Welfare
Benefit Fund (as defined in paragraph 1.72) or an individual medical account,
as defined in Code Section 415(1)(2), maintained by the adopting Employer,
which provides an Annual Addition as defined in paragraph 1.2, the amount of
Annual Additions which may be credited to the Participant's account for any
Limitation Year will not exceed the lesser of the Maximum Permissible Amount or
any other limitation contained in this Plan.  If the Employer contribution that
would otherwise be contributed or allocated to the Participant's account would
cause the Annual Additions for the Limitation Year to exceed the Maximum
Permissible Amount, the amount contributed or allocated will be reduced so that
the Annual Additions for the Limitation Year will equal the Maximum Permissible
Amount.  Prior to determining the Participant's actual Compensation for the
Limitation Year, the Employer may determine the Maximum Permissible Amount for
a Participant on the basis of a reasonable estimation of the Participant's
Compensation for the Limitation Year, uniformly determined for all Participants
similarly situated.  As soon as is administratively feasible after the end of
the Limitation Year, the Maximum Permissible Amount for the Limitation Year
will be determined on the basis of the Participant's actual Compensation for
the Limitation Year.

10.2     DISPOSITION OF EXCESS ANNUAL ADDITIONS  If pursuant to paragraph 10.1
or as a result of the allocation of forfeitures.  there is an Excess Amount,
the excess will be disposed of under one of the following methods as determined
in the Adoption Agreement.  If no election is made in the Adoption Agreement
then method "(a)" below shall apply.

(a)      Suspense Account Method

         (1)     Any nondeductible Employee Voluntary Contributions, to the
                 extent they would reduce the Excess Amount, will be returned
                 to the Participant;

         (2)     If after the application of paragraph (1) an Excess Amount
                 still exists, and the Participant is covered by the Plan at
                 the end of the Limitation Year, the Excess Amount in the
                 Participant's account will be used to reduce Employer
                 contributions (including any allocation of forfeitures) for
                 such Participant in the next Limitation Year, and each
                 succeeding Limitation Year if necessary;

         (3)     If after the application of paragraph (1) an Excess Amount
                 still exists, and the Participant is not covered by the Plan
                 at the end of the Limitation Year, the Excess Amount will be
                 held unallocated in a suspense account.  The suspense account
                 will be applied to reduce future Employer contributions
                 (including allocation of any forfeitures) for all remaining
                 Participants in the next Limitation Year, and each succeeding
                 Limitation Year if necessary;
<PAGE>   63

         (4)     If a suspense account is in existence at any time during the
                 Limitation Year pursuant to this paragraph, it will not
                 participate in the allocation of investment gains and losses.
                 If a suspense account is in existence at any time during a
                 particular Limitation Year, all amounts in the suspense
                 account must be allocated and reallocated to Participants'
                 accounts before any Employer contributions or any Voluntary
                 contributions may be made to the Plan for that Limitation
                 Year.  Excess amounts may not be distributed to Participants
                 or former Participants.

(b)      Spillover Method

         (1)     Any Excess Amount which would be allocated to the account of
                 an individual Participant under the Plan's allocation formula
                 will be reallocated to other Participants in the same manner
                 as other Employer contributions.  No such reallocation shall
                 be made to the extent that it will result in an Excess Amount
                 being created in such Participant's own account.

         (2)     To the extent that amounts cannot be reallocated under (1)
                 above, the suspense account provisions of (a) above will
                 apply.

10.3     PARTICIPATION IN THIS PLAN AND ANOTHER MASTER AND PROTOTYPE DEFINED
CONTRIBUTION PLAN, WELFARE BENEFIT FUND OR INDIVIDUAL MEDICAL ACCOUNT
MAINTAINED BY THE EMPLOYER  The Annual Additions which may be credited to a
Participant's account under this Plan for any Limitation Year will not exceed
the Maximum Permissible Amount reduced by the Annual Additions credited to a
Participant's account under the other Master or Prototype Defined Contribution
Plans, Welfare Benefit Funds, and individual medical accounts as defined in
Code Section 415(1)(2), maintained by the Employer, which provide an Annual
Addition as defined in paragraph 1.2, for the same Limitation Year.  If the
Annual Additions, with respect to the Participant under other Defined
Contribution Plans and Welfare Benefit Funds maintained by the Employer, are
less than the Maximum Permissible Amount and the Employer contribution that
would otherwise be contributed or allocated to the Participant's account under
this Plan would cause the Annual Additions for the Limitation Year to exceed
this limitation, the amount contributed or allocated will be reduced so that
the Annual Additions under all such plans and funds for the Limitation Year
will equal the Maximum Permissible Amount.  If the Annual Additions with
respect to the Participant under such other Defined Contribution Plans and
Welfare Benefit Funds in the aggregate are equal to or greater than the Maximum
Permissible Amount, no amount will be contributed or allocated to the
Participant's account under this Plan for the Limitation Year.  Prior to
determining the Participant's actual Compensation for the Limitation Year, the
Employer may determine the Maximum Permissible Amount for a Participant in the
manner described in paragraph 10.1.  As soon as administratively feasible after
the end of the Limitation Year, the Maximum Permissible Amount for the
Limitation Year will be determined on the basis of the Participant's actual
Compensation for the Limitation Year.

10.4     DISPOSITION OF EXCESS ANNUAL ADDITIONS UNDER TWO PLANS  If, pursuant
to paragraph 10.3 or as a result of forfeitures a Participant's Annual
Additions under this Plan and such other plans would result in an Excess
<PAGE>   64

Amount for a Limitation Year, the Excess Amount will be deemed to consist of
the Annual Additions last allocated except that Annual Additions attributable
to a Welfare Benefit Fund or individual medical account as defined in Code
Section 415(1)(2) will be deemed to have been allocated first regardless of the
actual allocation date.  If an Excess Amount was allocated to a Participant on
an allocation date of this Plan which coincides with an allocation date of
another plan, the Excess Amount attributed to this Plan will be the product of:

(a)      the total Excess Amount allocated as of such date, times

(b)      the ratio of:

         (1)     the Annual Additions allocated to the Participant for the
                 Limitation Year as of such date under the Plan, to

         (2)     the total Annual Additions allocated to the Participant for
                 the Limitation Year as of such date under this and all the
                 other qualified Master or Prototype Defined Contribution
                 Plans.

Any Excess Amount attributed to this Plan will be disposed of in the manner
described in paragraph 10.2.

10.5     PARTICIPATION IN THIS PLAN AND ANOTHER DEFINED CONTRIBUTION PLAN WHICH
IS NOT A MASTER OR PROTOTYPE PLAN  If the Participant is covered under another
qualified Defined Contribution Plan maintained by the Employer which is not a
Master or Prototype Plan, Annual Additions which may be credited to the
Participant's account under this Plan for any Limitation Year will be limited
in accordance with paragraphs 10.3 and 10.4 as though the other plan was a
Master or Prototype Plan, unless the Employer provides other limitations in the
Adoption Agreement.

10.6     PARTICIPATION IN THIS PLAN AND A DEFINED BENEFIT PLAN  If the Employer
maintains, or at any time maintained, a qualified Defined Benefit Plan (other
than Paired Plan #02001, #02002, #02003 or #02004) covering any Participant in
this Plan, the sum of the Participant 's Defined Benefit Plan Fraction and
Defined Contribution Plan Fraction will not exceed 1.0 in any Limitation Year.
For any Plan Year during which the Plan is Top-Heavy, the Defined Benefit and
Defined Contribution Plan Fractions shall be calculated in accordance with Code
Section 416(h).  The Annual Additions which may be credited to the
Participant's account under this Plan for any Limitation Year will be limited
in accordance with the Adoption Agreement.


                                   ARTICLE XI

                                 ADMINISTRATION


11.1     PLAN ADMINISTRATOR  The Employer shall be the named fiduciary and Plan
Administrator.  These duties shall include:

(a)      appointing the Plan's attorney, accountant, actuary, or any other
         party needed to administer the Plan,
<PAGE>   65


(b)      directing the Trustee/Custodian with respect to payments from the
         Fund,

(c)      communicating with Employees regarding their participation and
         benefits under the Plan, including the administration of all claims
         procedures,

(d)      filing any returns and reports with the Internal Revenue Service,
         Department of Labor, or any other governmental agency,

(e)      reviewing and approving any financial reports, investment reviews, or
         other reports prepared by any party appointed by the Employer under
         paragraph (a),

(f)      establishing a funding policy and investment objectives consistent
         with the purposes of the Plan and the Employee Retirement Income
         Security Act of 1974, and

(g)      construing and resolving any question of Plan interpretation.  The
         Plan Administrator's interpretation of Plan provisions including
         eligibility and benefits under the Plan is final, and unless it can be
         shown to be arbitrary and capricious will not be subject to "de novo"
         review.

11.2     TRUSTEE/CUSTODIAN  The Trustee/Custodian shall be responsible for the
administration of investments held in the Fund.  These duties shall include:

(a)      receiving contributions under the terms of the Plan,

(b)      making distributions from the Fund in accordance with written
         instructions received from an authorized representative of the
         Employer, and

(c)      keeping accurate records reflecting its administration of the Fund and
         making such records available to the Employer for review and audit.
         Within 90 days after each Plan Year, and within 90 days after its
         removal or resignation, the Trustee/Custodian shall file with the
         Employer an accounting of its administration of the Fund during such
         year or from the end of the preceding Plan Year to the date of removal
         or resignation.  Such accounting shall include a statement of cash
         receipts and disbursements since the date of its last accounting and
         shall contain an asset list showing the fair market value of
         investments held in the Fund as of the end of the Plan Year.  The
         value of marketable investments shall be determined using the most
         recent price quoted on a national securities exchange or over the
         counter market.  The value of non-marketable investments shall be
         determined in the sole judgement of the Trustee/Custodian which
         determination shall be binding and conclusive.  The value of
         investments in securities or obligations of the Employer in which
         there is no market shall be determined in the sole judgement of the
         Employer, and the Trustee/Custodian shall have no responsibility with
         respect to the valuation of such assets.  The Employer shall review
         the Trustee/Custodian's accounting and notify the Trustee/Custodian in

         advisor which may or may not be a subsidiary or an affiliate of the
         Trustee, attorneys or other professionals as the Trustee may deem
         necessary or advisable in the performance of its duties.

The Trustee's/Custodian's duties shall be limited to those described above.
The Employer shall be responsible for any other administrative duties required
under the Plan or by applicable law.

11.3     ADMINISTRATIVE FEES AND EXPENSES  All reasonable costs, charges and
expenses incurred by the Trustee/Custodian in connection with the
administration of the Fund and all reasonable costs, charges and expenses
incurred by the Plan Administrator in connection with the administration of the
Plan (including fees for legal services rendered to the Trustee/Custodian or
Plan Administrator) may be paid by the Employer, but if not paid by the
Employer when due, shall be paid from the Fund.  Such reasonable compensation
to the Trustee/Custodian as may be agreed upon from time to time between the
Employer and the Trustee/Custodian and such reasonable compensation to the Plan
Administrator as may be agreed upon from time to time between the Employer and
Plan Administrator may be paid by the Employer, but if not paid by the Employer

to liquidate trust assets to cover its fees.  Notwithstanding the foregoing, no
compensation other than reimbursement for expenses shall be paid to a Plan
Administrator or a Trustee/Custodian who is the Employer or a full-time
Employee of the Employer.  In the event any part of the Trust/Custodial Account
becomes subject to tax, all taxes incurred will be paid from the Fund unless
the Plan Administrator advises the Trustee/Custodian not to pay such tax.

11.4     DIVISION OF DUNES AND INDEMNIFICATION

(a)      The Trustee/Custodian shall have the authority and discretion to
         manage and govern the Fund to the extent provided in this instrument,
         but does not guarantee the Fund in any manner against investment loss
         or depreciation in asset value, or guarantee the adequacy of the Fund
         to meet and discharge all or any liabilities of the Plan.

(b)      The Trustee/Custodian shall not be liable for the making, retention or
         sale of any investment or reinvestment made by it, as herein provided,
         or for any loss to, or diminution of the Fund, or for any other loss
         or damage which may result from the discharge of its duties hereunder
         except to the extent it is judicially determined that the
         Trustee/Custodian has failed to exercise the care, skill, prudence and
         diligence under the circumstances then prevailing that a prudent
         person acting in a like capacity and familiar with such matters would
         use in the conduct of an enterprise of a like character and like aims.
<PAGE>   67

(c)      The Employer warrants that all directions issued to the
         Trustee/Custodian by it, the Plan Administrator, an investment manager
         appointed pursuant to Section 13.7, or any other authorized person,
         will be in accordance with the terms of the Plan and not contrary to
         the provisions of the Employee Retirement Income Security Act of 1974

(d)      The Trustee/Custodian shall not be answerable for any action taken
         pursuant to any direction, consent, certificate, or other paper or
         document on the belief that the same is genuine and signed by the
         proper person.  All directions by the Employer, Participant or the
         Plan Administrator shall be in writing.  The Employer shall deliver to
         the Trustee/Custodian certificates evidencing the individual or
         individuals authorized to act as set forth in the Adoption Agreement
         or as the Employer may subsequently inform the Trustee/Custodian in
         writing and shall deliver to the Trustee/Custodian specimens of their
         signatures.

(e)      The duties and obligations of the Trustee/Custodian shall be limited
         to those expressly imposed upon it by this instrument or subsequently
         agreed upon by the parties.  Responsibility for administrative duties
         required under the Plan or applicable law not expressly imposed upon
         or agreed to by the Trustee/Custodian, shall rest solely with the
         Employer.

(f)      The Trustee/Custodian shall be indemnified and saved harmless by the
         Employer from and against any and all liability to which the
         Trustee/Custodian may be subjected, including all expenses reasonably
         incurred in its defense, for any action or failure to act resulting
         from compliance with the instructions of the Employer, the employees
         or agents of the Employer, the Plan Administrator, or any other
         fiduciary to the Plan, and for any liability arising from the actions
         or non-actions of any predecessor Trustee/Custodian or fiduciary or
         other fiduciaries of the Plan.

(g)      The Trustee/Custodian shall not be responsible in any way for the
         application of any payments it is directed to make or for the adequacy
         of the Fund to meet and discharge any and all liabilities under the
         Plan.

                          TRUST FUND/CUSTODIAL ACCOUNT


12.1     THE FUND  The Fund shall consist of all contributions made under
Article III and Article IV of the Plan and the investment thereof and earnings
thereon.  All contributions and the earnings thereon less payments made under
the terms of the Plan, shall constitute the Fund.  The Fund shall be
administered as provided herein.

12.2 CONTROL OF PLAN ASSETS  The assets of the Fund or evidence of ownership
shall be held by the Trustee/Custodian under the terms of the Plan and
Trust/Custodial Account.  If the assets represent amounts transferred from
another trustee/custodian under a former Plan, the
<PAGE>   68

Trustee/Custodian named hereunder shall not be responsible for any actions of
the prior fiduciary including the review of the propriety of any investment
under the former plan, said review to be the responsibility of the Employer.

12.3     EXCLUSIVE BENEFIT RULES  No part of the Fund shall be used for, or
divened to, purposes other than for the exclusive benefit of Participants,
former Participants with a vested interest, and the Beneficiary or
Beneficiaries of deceased Participants having a vested interest in the Fund at
death.

12.4     ASSIGNMENT AND ALIENATION OF BENEFITS  No right or claim to, or
interest in, any part of the Fund, or any payment therefrom, shall be
assignable, transferable, or subject to sale, mortgage, pledge, hypothecation,
commutation, anticipation, garnishment, attachment, execution, or levy of any
kind, and the Trustee/Custodian shall not recognize any attempt to assign,
transfer, sell, mortgage, pledge, hypothecate, commute, or anticipate the same,
except to the extent required by law.  The preceding sentence shall also apply
to the creation, assignment, or recognition of a right to any benefit payable
with respect to a Participant pursuant to a domestic relations order, unless
such order is determined to be a Qualified Domestic Relations Order, as defined
in Code Section 414(p), or any domestic relations order entered before January
1, 1985 which the Plan attorney and Plan Administrator deem to be qualified.

19.5     DETERMINATION OF QUALIFIED DOMESTIC RELATIONS ORDER (QDRO)  A
Qualified Domestic Relations Order shall specifically state all of the
following in order to be deemed a QDRO:

(a)      The name and last known mailing address (if any) of the Participant
         and of each alternate payee covered by the Order.  However, if the
         QDRO does not specify the current mailing address of the alternate
         payee, but the Plan Administrator has independent knowledge of that
         address, the QDRO will still be valid.

(b)      The dollar amount or percentage of the Participant's benefit to be
         paid by the Plan to each alternate payee, or the manner in which the
         amount or percentage will be determined.

(c)      The number of payments or period for which the order applies.

(d)      The specific plan (by name) to which the Order applies.

The Order shall not be deemed a QDRO if it requires the Plan to provide:

(e)      any type or form of benefit, or any option not already provided for in
         the Plan;

(f)      increased benefits, or benefits in excess of the Participant's vested
         rights;

(g)      payment of a benefit earlier than allowed by the Plan's earliest
         retirement provisions or in the case of a profit- sharing plan, prior
         to the allowability of in-service withdrawals, or
<PAGE>   69


(h)      payment of benefits to an alternate payee which are required to be
         paid to another alternate payee under another QDRO.

Promptly, upon receipt of a Domestic Relations Order which may or may not be
"Qualified" the Plan Administrator shall notify the Participant and any
alternate payee(s) named in the Order of such receipt, and include a copy of
this paragraph 12.5.  The Plan Administrator shall then forward the Order to
the Plan's legal counsel for an opinion as to whether or not the Order is in
fact "Qualified" as defined in Code Section 414(p).  Within a reasonable time
after receipt of the Order, not to exceed 60 days, the Plan's legal counsel
shall make a determination as to its "Qualified" status and the Participant and
any alternate payee(s) shall be promptly notified in writing of the
determination.

If the "Qualified" status of the Order is in question, there will be a delay in
any payout to any payee including the Participant, until the status is
resolved.  In such event, the Plan Administrator shall segregate the amount
that would have been payable to the alternate payee(s) if the Order had been
deemed a QDRO.  If the Order is not Qualified, or the status is not resolved
(for example, it has been sent back to the Court for clarification or
modification) within 18 months beginning with the date the first payment would
have to be made under the Order, the Plan Administrator shall pay the
segregated amounts plus interest to the person(s) who would have been entitled
to the benefits had there been no Order.  If a determination as to the
Qualified status of the Order is made after the 18-month period described
above, then the Order shall only be applied on a prospective basis.  If the
Order is determined to be a QDRO, the Participant and alternate payee(s) shall
again be notified promptly after such determination.  Once an Order is deemed a
QDRO, the Plan Administrator shall pay to the alternate payee(s) all the
amounts due under the QDRO, including segregated amounts plus interest which
may have accrued during a dispute as to the Order's qualification.

Unless specified otherwise in the Adoption Agreement, the earliest retirement
age with regard to the Participant against whom the order is entered shall be
the date the order is determined to be qualified.  This will only allow payouts
to alternate payee(s) and not the Participant.

                                  INVESTMENTS


13.1     FIDUCIARY STANDARDS  The Trustee shall invest and reinvest income in
the same Fund in accordance with the investment objectives established by the
Employer, provided that:

(a)      such investments are prudent under the Employee Retirement Income
         Security Act of 1974 and the regulations promulgated thereunder,

(b)      such investments are sufficiently diversified or otherwise insured or
         guaranteed to minimize the risk of large losses, and
<PAGE>   70

(c)      such investments are similar to those which would be purchased by
         another professional money manager for a like plan with similar
         investment objectives.

13.2     FUNDING ARRANGEMENT  The Employer shall, in the Adoption Agreement,
appoint a Trustee to administer the Fund and/or a Custodian to have custody of
the Fund.  The Trustee shall invest the Fund in any of the alternatives
available under paragraph 13.3.  If a Custodian is appointed, the Fund shall be
invested as provided in paragraph 13.4.

13.3     INVESTMENT ALTERNATIVES OF THE TRUSTEE  The Trustee shall implement an
investment program based on the Employer's investment objectives and the
Employee Retirement Income Security Act of 1974.  In addition to powers given
by law, the Trustee may:

(a)      invest the Fund in any form of property, including common and
         preferred stocks, exchange traded put and call options, bonds, money
         market instruments, mutual funds (including funds for which the
         Trustee/Custodian or its subsidiaries or its affiliates serve as
         investment advisor), savings accounts, certificates of deposit,
         Treasury bills, insurance policies and contracts, or in any other
         property, real or personal, having a ready market including securities
         issued by the Trustee and/or affiliates of the Trustee.  The Trustee
         may also make loans to Plan Participants in accordance with paragraph
         13.5 hereof.  The Trustee may invest in its own deposits, and if
         applicable those of affiliates, which bear a reasonable interest rate.
         No portion of any Qualified Voluntary Contribution, or the earnings
         thereon, may be invested in life insurance contracts or, as with any
         Participant-directed investment, in tangible personal property
         characterized by the IRS as a collectible,

(b)      invest any assets of the Fund in a group or collective trust
         established to permit the pooling of funds of separate pension and
         profit-sharing trusts, provided such group or collective trust is
         qualified under Code Section 401(a) and exempt under Code Section
         501(a) (or the applicable corresponding provision of any other Revenue
         Act) or to any other common, collective, or commingled trust fund
         which has been or may hereafter be established and maintained by the
         Trustee/Custodian and/or affiliates of the Trustee/Custodian.  Such
         commingling of assets of the Fund with assets of other qualified
         trusts is specifically authorized, and to the extent of the investment
         of the Fund in such a group or collective trust, the terms of the
         instrument establishing the group or collective trust shall be a part
         hereof as though set forth herein.  The terms of said instrument(s)
         may authorize the Trustee of the group or collective trust to engage
         in securities lending transactions where fees may be deducted from the
         group or collective trust's loan income,

(c)      invest the Fund in the common stock, debt obligations, or any other
         security issued by the Employer or by an affiliate of the Employer
         within the limitations provided under Sections 406, 407, and 408 of
         the Employee Retirement Income Security Act of 1974 and further
         provided that such investment does not constitute a prohibited
         transaction under Code Section 4975.  Any such investment in Employer
<PAGE>   71

         securities shall only be made upon written direction of the Employer
         who shall be solely responsible for propriety of such investment,

(d)      hold cash uninvested and deposit same with any banking or savings
         institution, including iis own banking department or the banking
         department of an affiliate,

(e)      join in or oppose the reorganization, recapitalization, consolidation,
         sale or merger of corporations or properties, including those in which
         it is interested as Trustee, upon such terms as it deems wise,

(f)      hold investments in nominee or bearer form,

(g)      vote proxies and if appropriate pass them on to any investment manager
         which may have directed the investment in the equity giving rise to
         the proxy,

(h)      exercise all ownership rights with respect to assets held in the Fund.

13.4     INVESTMENT ALTERNATIVES OF THE CUSTODIAN  The Custodian shall be
depository of all or part of the Fund and shall, at the written direction of
the Trustee hold any assets received from the Trustee or its agents.  The
Custodian may rely upon any order, certificate, notice, direction or other
written directive issued by the Trustee or its agents.  The Custodian shall
receive and deliver assets as instructed by the Trustee or its agents, or an
investment manager appointed pursuant to Section 13.7 through written
direction.  To the extent that the Custodian holds title to Plan assets and
such ownership requires action on the part of the registered owner, such action
will be taken by the Custodian only upon receipt of specific written
instructions from the Trustee or its agents or an investment manager.  Proxies
shall be voted by or pursuant to the express direction of the Trustee or
authorized agent of the Trustee.  The Custodian shall not give any investment
advice, including any opinion on the prudence of directed investments.  The
Employer and Trustee and the agents thereof assume all responsibility for
adherence to fiduciary standards under the Employee Retirement Income Security
Act of 1974 (ERISA) and all amendments thereof, and regulations thereunder.

13.5     PARTICIPANT LOANS  If agreed upon by the Trustee and permitted by the
Employer in the Adoption Agreement, a Plan Participant may make application to
the Employer requesting a loan from the Fund.  The Employer shall have the sole
right to approve or disapprove a Participant's application provided that loans
shall be made available to all Participants on a reasonably equivalent basis.
Loans shall not be made available to highly compensated employees [as defined
in Code Section 414(q)] in an amount greater than the amount made available to
other Employees.  Any loan granted hereunder shall be made subject to the
following rules:

(a)      No loan granted hereunder shall exceed the lesser of (i) $50,000
         reduced by the excess, if any, of the highest outstanding balance of
         loans during the one year period ending on the day before the loan is
         made, over the outstanding balance of loans from the Plan on the date
         the loan is made or (ii) one-half of the fair market value of a
         Participant's vested account balance built up from Employer
         Contributions, Voluntary Contributions, and Rollover Contributions.
<PAGE>   72

         If the Participant's vested account balance is $20,000 or less, the
         maximum loan shall not exceed the lesser of $10,000 or 100% of the
         Participant's vested account balance.  For the purpose of the above
         limitation, all loans from all plans of the Employer and other members
         of a group of employers described in Code Sections 414(b), 414(c), and
         414(m) are aggregated.  An assignment or pledge of any portion of the
         Participant's interest in the Plan and a loan, pledge, or assignment
         with respect to any insurance contract purchased under the Plan, will
         be treated as a loan under this paragraph.

(b)      All applications must be made on forms provided by the Employer and
         must be signed by the Participant.

(c)      Any loan granted hereunder shall bear interest at a rate reasonable at
         the time of application, considering the purpose of the loan and the
         rate being charged by representative commercial banks in the local
         area for a similar loan unless the Employer sets forth a different
         method for determining loan interest rates in its loan procedures.
         The loan agreement shall also provide that the payment of principal
         and interest be amortized in level payments not less frequently than
         quarterly.

(d)      The term of such loan shall not exceed five years except in the case
         of a loan for the purpose of acquiring any house, apartment,
         condominium, or mobile home (not used on a transient basis) which is
         used or is to be used within a reasonable time as the principal
         residence of the Participant.  The term of such loan shall be
         determined by the Employer considering the maturity dates quoted by
         representative commercial banks in the local area for a similar loan.

(e)      The principal and interest paid by a Participant on his or her loan
         shall be credited to the Fund in the same manner as for any other Plan
         investment.  If elected in the Adoption Agreement, loans may be
         treated as segregated investments of the individual Participants.
         This provision is not available if its election will result in
         discrimination in operation of the Plan.

(f)      If a Participant's loan application is approved by the Employer, such
         Participant shall be required to sign a note, loan agreement, and
         assignment of one-half of his or her interest in the Fund as
         collateral for the loan.  The Participant, except in the case of a
         profit-sharing plan satisfying the requirements of paragraph 8.7, must
         obtain the consent of his or her Spouse, if any, within the 90 day
         period before the time his or her account balance is used as security
         for the loan.  A new consent is required if the account balance is
         used for any renegotiation, extension, renewal or other revision of
         the loan, including an increase in the amount thereof.  The consent
         must be written, must acknowledge the effect of the loan, and must be
         witnessed by a plan representative or notary public.  Such consent
         shall thereafter be binding with respect to the consenting Spouse or
         any subsequent Spouse.

(g)      If a valid Spousal consent has been obtained, then, notwithstanding
         any other provision of this Plan, the portion of the Participant's
         vested account balance used as a security interest held by the Plan
<PAGE>   73

         by reason of a loan outstanding to the Participant shall be taken into
         account for purposes of determining the amount of the account balance
         payable at the time of death or distribution, but only if the
         reduction is used as repayment of the loan.  If less than 100% of the
         Participant's vested account balance (determined without regard to the
         preceding sentence) is payable to the surviving Spouse, then the
         account balance shall be adjusted by first reducing the vested account
         balance by the amount of the security used as repayment of the loan,
         and then determining the benefit payable to the Surviving Spouse.

(h)      The Employer may also require additional collateral in order to
         adequately secure the loan.

(i)      A Participant's loan shall immediately become due and payable if such
         Participant terminates employment for any reason or fails to make a
         principal and/or interest payment as provided in the loan agreement.
         If such Participant terminates employment, the Employer shall
         immediately request payment of principal and interest on the loan.  If
         the Participant refuses payment following termination, the Employer
         shall reduce the Participant's vested account balance by the remaining
         principal and interest on his or her loan.  If the Participant's
         vested account balance is less than the amount due, the Employer shall
         take whatever steps are necessary to collect the balance due directly
         from the Participant.  However, no foreclosure on the Participant's
         note or attachment of the Participant's account balance will occur
         until a distributable event occurs in the Plan.

(j)      No loans will be made to Owner-Employees (as defined in paragraph
         1.38) or Shareholder-Employees (as defined in paragraph 1.58), unless
         an exemption from the prohibited transactions rules is first obtained
         from the Department of Labor.

13.6     INSURANCE POLICIES  If agreed upon by the Trustee and approved by the
Employer in the Adoption Agreement, Employees may elect the purchase of life
insurance policies under the Plan.  If elected, the maximum annual premium for
a whole life policy shall not exceed 50% of the aggregate Employer
contributions allocated to the account of a Participant.  For profit-sharing
plans the 50% test need only be applied against Employer contributions
allocated in the last two years.  Whole life policies are policies with both
nondecreasing death benefits and nonincreasing premiums.  The maximum annual
premium for term contracts or universal life policies and all other policies
which are not whole life shall not exceed 25% of aggregate Employer
contributions allocated to the account of a Participant.  The two year rule for
profit-sharing plans again applies.  The maximum annual premiums for a
Participant with both a whole life and a term contract or universal life
policies shall be limited to one-half of the whole life premiums plus the term
premium but shall not exceed 25 % of the aggregate Employer contributions
allocated to the account of a Participant, subject to the two year rule for
profit-sharing plans.  Any policies purchased under this Plan shall be held
subject to the following rules:

(a)      The Trustee shall be applicant and owner of any policies issued.

(b)      All policies or contracts purchased shall be endorsed as
         nontransferable, and must provide that proceeds will be payable to the
<PAGE>   74

         Trustee; however, the Trustee shall be required to pay over all
         proceeds of the contracts to the Participant's Designated Beneficiary
         in accordance with the distribution provisions of this Plan.  Under no
         circumstances shall the Trust retain any part of the proceeds.

(c)      Each Participant shall be entitled to designate a beneficiary under
         the terms of any contract issued; however, such designation will be
         given to the Trustee which must be the named beneficiary on any
         policy.  Such designation shall remain in force, until revoked by the
         Participant, by filing a new beneficiary form with the Trustee.  A
         Participant's Spouse will be the Designated Beneficiary of the
         proceeds in all circumstances unless a Qualified Election has been
         made in accordance with paragraph 8.4.  The beneficiary of a deceased
         Participant shall receive, in addition to the proceeds of the
         Participant's policy or policies, the amount credited to such
         Participant's investment account.

(d)      A Participant who is uninsurable or insurable at substandard rates,
         may elect to receive a reduced amount of insurance, if available, or
         may waive the purchase of any insurance.

(e)      All dividends or other returns received on any policy purchased shall
         be applied to reduce the next premium due on such policy, or if no
         further premium is due, such amount shall be credited to the Fund as
         part of the account of the Participant for whom the policy is held.

(f)      If Employer contributions are inadequate to pay all premiums on all
         insurance policies, the Trustee may, at the option of the Employer,
         utilize other amounts remaining in each Participant's account to pay
         the premiums on-his or her respective policy or policies, allow the
         policies to lapse, reduce the policies to a level at which they may be
         maintained, or borrow against the policies on a prorated basis,
         provided that the borrowing does not discriminate in favor of the
         policies on the lives of Officers, Shareholders, and highly
         compensated Employees.

(g)      On retirement or termination of employment of a Participant, the
         Employer shall direct the Trustee to cash surrender the Participant's
         policy and credit the proceeds to his or her account for distribution
         under the terms of the Plan.  However, before so doing, the Trustee
         may first offer to transfer ownership of the policy to the Participant
         in exchange for payment by the Participant of the cash value of the
         policy at the time of transfer.  Such payment shall be credited to the
         Participant's account for distribution under the terms of the Plan.
         All distributions resulting from the application of this paragraph
         shall be subject to the Joint and Survivor Annuity Rules of Article
         VIII, if applicable.

(h)      The Employer shall be solely responsible to see that these insurance
         provisions are administered properly and that if there is any conflict
         between the provisions of this Plan and any insurance contracts issued
         that the terms of this Plan will control.

13.7     EMPLOYER INVESTMENT DIRECTION  If agreed upon by the Trustee and
approved by the Employer in the Adoption Agreement, the Employer shall have
<PAGE>   75

the right to direct the Trustee with respect to investments of the Fund, may
appoint an investment manager (registered as an investment advisor under the
Investment Advisors Act of 1940) to direct investments, or may give the Trustee
investment management responsibility.  The Employer may purchase and sell
interests in a registered investment company (i.e., mutual funds) for which the
Sponsor, its parent, affiliates, subsidiaries, or successors may serve as
investment advisor and receive compensation from the registered investment
company for its services as investment advisor.  The Employer shall advise the
Trustee in writing regarding the retention of investment powers, the
appointment of an investment manager, or the delegation of investment powers to
the Trustee.  The Trustee may rely upon any order, certificate, notice,
direction or other written directive issued by the Employer, investment manager
or any other authorized party which the Trustee believes to be genuine.  In the
absence of such written directive, the Trustee may invest the available cash in
its discretion in an appropriate interim investment until specific investment
directions are received and shall not be responsible for a resulting loss.
Such instructions regarding the delegation of investment responsibility shall
remain in force until revoked or amended in writing.  The Employer must provide
the Trustee with written notice of the termination of the appointment of an
investment manager.  The Trustee shall not be responsible for the propriety of
any directed investment made and shall not be required to consult with or
advise the Employer regarding the investment quality of any directed investment
held hereunder.  The Trustee shall not be responsible for any loss resulting to
the Fund by reason of any sale or investment made pursuant to the direction of
the Employer or an investment manager.  Notwithstanding anything in this Plan
to the contrary, the Trustee shall be indemnified and saved harmless by the
Employer from any and all personal liability to which the Trustee may be
subjected by carrying out any directions of the Employer or an investment
manager, including all expenses reasonably incurred in its defense in the event
the Employer fails to provide such; provided, however, the Trustee shall not be
so indemnified if it participates knowingly in, or knowingly undertakes to
conceal, an act or omission of an investment manager, having actual knowledge
that such is a breach of a fiduciary duty.  The Trustee shall not be deemed to
have knowingly participated in or knowingly undertaken to conceal an act or
omission of an investment manager with knowledge that such act or omission was
a breach of fiduciary duty by merely complying with directions of an investment
manager, or for failure to act in the absence of directions of an investment
manager, or by reason of maintaining accounting records.  If the Employer fails
to designate an investment manager, the Trustee shall have full investment
authority.  If the Employer does not issue investment directions, the Trustee
shall have authority to invest the Fund in its sole discretion.  While the
Employer may direct the Trustee with respect to Plan investments, the Employer
may not:

(a)      borrow from the Fund or pledge any of the assets of the Fund as
         security for a loan,

(b)      buy property or assets from or sell property or assets to the Fund,

(c)      charge any fee for services rendered to the Fund, or

(d)      receive any services from the Fund on a preferential basis.
<PAGE>   76

13.8     EMPLOYEE INVESTMENT DIRECTION  If agreed to by the Trustee and
approved by the Employer in the Adoption Agreement, Participants shall be given
the option to direct the investment of their personal contributions and their
share of the Employer's contribution among alternative investment funds
established as part of the overall Fund.  Unless otherwise specified by the
Employer in the Adoption Agreement, such investment funds shall be restricted
to funds offered by the Trustee/Custodian.  If investments outside the
Trustee/Custodian's control are allowed, Participants may not direct that
investments be made in collectibles, other than U.S.  Government or State
issued gold and silver coins.  In this connection, a Participant's right to
direct the investment of any contribution shall apply only to selection of the
desired fund.  The following rules shall apply to the administration of such
funds.

(a)      At the time an Employee becomes eligible for the Plan, he or she shall
         complete an investment designation form stating the percentage of his
         or her contributions to be invested in the available funds.

(b)      A Participant may change his or her election with respect to future
         contributions by filing a new investment designation form with the
         Employer in accordance with the procedures established by the Plan
         Administrator.

(c)      A Participant may elect to transfer all or part of his or her balance
         from one investment fund to another by filing an investment
         designation form with the Employer in accordance with the procedures
         established by the Plan Administrator.

(d)      The Employer shall be responsible when transmitting Employee and
         Employer contributions to show the dollar amount to be credited to
         each investment fund for each Employee.

(e)      Except as otherwise provided in the Plan, neither the Trustee, nor the
         Custodian, nor the Employer, nor any fiduciary of the Plan shall be
         liable to the Participant or any of his or her beneficiaries for any
         loss resulting from action taken at the direction of the Participant
         and shall be indemnified and held harmless.


                                  ARTICLE XIV

                              TOP-HEAVY PROVISIONS


14.1     APPLICABILITY OF RULES  If the Plan is or becomes Top- Heavy in any
Plan Year beginning after 1983, the provisions of this Article will supersede
any conflicting provisions in the Plan or Adoption Agreement.

14.2     MINIMUM CONTRIBUTION  Notwithstanding any other provision in the
Employer's Plan, for any Plan Year in which the Plan is Top-Heavy, the
aggregate Employer contributions and forfeitures allocated on behalf of any
Participant (without regard to any Social Security contribution) under this
Plan and any other Defined Contribution Plan of the Employer shall be
determined as follows:
<PAGE>   77

(a)      When the Employer maintains one Plan or a combination of Paired or
         non-paired Defined Contribution Plans and no Defined Benefit Plans
         which are Top-Heavy or Super Top- Heavy, the Employer will contribute
         the lesser of 3% of such Participant's Compensation or the largest
         percentage of Employer contributions and forfeitures, as a percentage
         of the first $200,000 of the Key Employee's Compensation, allocated on
         behalf of any Key Employee for that year.

(b)      Minimum Top-Heavy Contributions for Paired Defined Contribution and
         Defined Benefit Plans where the Plans are not Super Top-Heavy:

         (1)     If an Employee participates in Paired Defined Contribution
                 Plan #04001 or #04002 and also participates in Paired Defined
                 Benefit Plan #02001, #02002, #02003 or #02004, the Employer
                 shall provide a minimum non- integrated benefit of 3% of the
                 highest 5-consecutive year average Compensation for each
                 non-Key Employee who participates in such Defined Benefit
                 Plan, not to exceed a cumulative accrued benefit of 30%.

         (2)     If an Employee participates in Paired Defined Contribution
                 Plan #04001 or #04002, but does not participate in Paired
                 Defined Benefit Plan #02001, #02002, #02003 or #02004, the
                 Employer shall make a minimum non-integrated allocation of
                 Employer contributions and forfeitures (in the aggregate under
                 all Defined Contribution Plans) of 4% of each eligible
                 Participant's Top-Heavy Compensation.

(c)      Minimum Top-Heavy Contributions for Paired Defined Contribution and
         Defined Benefit Plans where the Plans are Super Top-Heavy:

         (1)     If an Employee participates in Defined Contribution Plan
                 #04001 or #04002 and in Paired Defined Benefit Plan #02001,
                 #02002, #02003 or #02004, the Employer shall provide a minimum
                 non-integrated benefit of 2% of the highest 5-consecutive year
                 average Compensation for each non-Key Employee who
                 participates in such Defined Benefit Plan, not to exceed a
                 cumulative accrued benefit of 20%.

         (2)     If an Employee participates in Defined Contribution Plan
                 #04001 or #04002, but does not participate in Paired Defined
                 Benefit Plan #02001, #02002, #02003 or #02004, the minimum
                 contribution requirements at paragraph 14.2(b)(2) shall apply
                 except that the minimum non- integrated allocation percentage
                 shall be 3% instead of 4%.

(d)      If the Employer maintains or maintained a Defined Benefit Plan which is
         not paired, the provisions of the "Limitations on Allocations" section
         of the Adoption Agreement shall apply.

Each Participant who is employed by the Employer on the last day of the Plan
Year shall be entitled to receive an allocation of the Employer's minimum
contribution for such Plan Year.  The minimum allocation applies even though
under other Plan provisions the Participant would not otherwise be entitled to
receive an allocation, or would have received a lesser allocation for the year
because the Participant fails to make Mandatory
<PAGE>   78

Contributions to the Plan, the Participant's Compensation is less than a stated
amount, or the Participant fails to complete 1,000 Hours of Service (or such
lesser number designated by the Employer in the Adoption Agreement during the
Plan Year.)  A Paired profit-sharing plan designated to provide the minimum
Top-Heavy contribution must do so regardless of profits.  Unless the Employer
specifies otherwise in the Adoption Agreement, the minimum Top-Heavy
contribution will be allocated to the accounts of all eligible Participants,
even if they are Key Employees.

For purposes of computing the minimum allocation, Compensation shall mean
Compensation as defined in the second paragraph of paragraph 1.8 of the Plan.

The Top-Heavy minimum contribution does not apply to any Participant to the
extent the Participant is covered under any other plan(s) of the Employer and
the Employer has provided in the Adoption Agreement that the minimum allocation
or benefit requirements applicable to Top-Heavy Plans will be met in the other
plan(s).

14.3     MINIMUM VESTING  For any Plan Year in which this Plan is Top-Heavy,
the minimum vesting schedule elected by the Employer in the Adoption Agreement
will automatically apply to the Plan.  If the vesting schedule selected by the
Employer in the Adoption Agreement is less liberal than the allowable schedule,
the schedule will automatically be modified.  If the vesting schedule under the
Employer's Plan shifts in or out of the Top-Heavy schedule for any Plan Year,
such shift is an amendment to the vesting schedule and the election in
paragraph 9.8 of the Plan applies.  The minimum vesting schedule applies to all
benefits within the meaning of Section 411(a)(7) of the Code except those
attributable to Employee contributions, including benefits accrued before the
effective date of Section 416 of the Code and benefits accrued before the Plan
became Top-Heavy.  Further, no reduction in vested benefits may occur in the
event the Plan's status as Top-Heavy changes for any Plan Year.  However, this
paragraph does not apply to the account balances of any Employee who does not
have an Hour of Service after the Plan initially becomes Top-Heavy and such
Employee's account balance attributable to Employer contributions and
forfeitures will be determined without regard to this paragraph.

14.4     LIMITATIONS ON ALLOCATIONS  In any Plan Year in which the Top-Heavy
Ratio exceeds 90% (i.e., the Plan becomes Super Top-Heavy), the denominators of
the Defined Benefit Fraction (as defined in paragraph 1.11) and Defined
Contribution Fraction (as defined in paragraph 1.14) shall be computed using
100% of the dollar limitation instead of 125%.


                                   ARTICLE XV

                           AMENDMENT AND TERMINATION


15.1     AMENDMENT BY SPONSOR  The Sponsor may amend any or all provisions of
this Plan and Trust/Custodial Account at any time without obtaining the
approval or consent of any Employer which has adopted this Plan and
Trust/Custodial Account provided that no amendment shall authorize or permit
any part of the corpus or income of the Fund to be used for or
<PAGE>   79

diverted to purposes other than for the exclusive benefit of Participants and
their beneficiaries, or eliminate an optional form of distribution.  In the
case of a mass-submitted plan, the mass- submitter shall amend the Plan on
behalf of the Sponsor.

15.2     AMENDMENT BY EMPLOYER  The Employer may amend any option in the
Adoption Agreement, and may include language as permitted in the Adoption
Agreement,

(a)      to satisfy Code Section 415, or

(b)      to avoid duplication of minimums under Section 416 of the Code,

because of the required aggregation of multiple plans.

The Employer may add certain model amendments published by the Internal Revenue
Service which specifically provide that their adoption will not cause the Plan
to be treated as individually designed.

If the Employer amends the Plan and Trust/Custodial Account other than as
provided above, including providing for a waiver of minimum funding under Code
Section 412(d), the Employer's Plan shall no longer participate in this
Prototype Plan and will be considered an individually designed plan for which
the Employer must obtain a separate determination letter.

15.3     TERMINATION  The Employer shall have the right to terminate the Plan
upon 60 days notice in writing to the Trustee/Custodian.  If the Plan is
terminated, partially terminated, or if there is a complete discontinuance of
contributions under a profit-sharing plan maintained by the Employer, all
amounts credited to the accounts of Participants shall vest and become
nonforfeitable.  In the event of a partial termination, only those who separate
from Service shall be fully vested.  In the event of termination, the Employer
shall direct the Trustee/Custodian with respect to the distribution of accounts
to or for the exclusive benefit of Participants or their beneficiaries.  The
Trustee/Custodian shall dispose of the Fund in accordance with the written
directions of the Plan Administrator, provided that no liquidation of assets
and payment of benefits, (or provision therefor), shall actually be made by the
Trustee/Custodian until after it is established by the Employer in a manner
satisfactory to the Trustee/Custodian, that the applicable requirements, if
any, of the Employee Retirement Income Security Act of 1974 and the Internal
Revenue Code governing the termination of employee benefit plans, have been or
are being, complied with, or that appropriate authorizations, waivers,
exemptions, or variances have been, or are being obtained.  The
Trustee/Custodian shall not be obliged to distribute the Fund until it receives
notice of a favorable ruling from the Internal Revenue Service upon the
Employer's application for determination as to the effect of termination.

15.4     QUALIFICATION OF EMPLOYER'S PLAN  If the adopting Employer fails to
attain or retain Internal Revenue Service qualification, such Employer's Plan
shall no longer participate in this Prototype Plan and will be considered an
individually designed plan.

15.5     MERGERS AND CONSOLIDATIONS
<PAGE>   80


(a)      In the case of any merger or consolidation of the Employer's Plan
         with, or transfer of assets or liabilities of the Employer's Plan to,
         any other plan, Participants in the Employer's Plan shall be entitled
         to receive benefits immediately after the merger, consolidation, or
         transfer which are equal to or greater than the benefits they would
         have been entitled to receive immediately before the merger,
         consolidation, or transfer if the Plan had then terminated.

(b)      Any corporation into which the Trustee/Custodian or any successor
         trustee/custodian may be merged or with which it may be consolidated,
         or any corporation resulting from any merger or consolidation to which
         the Trustee/Custodian or any successor trustee/custodian may be a
         party, or any corporation to which all or substantially all the trust
         business of the Trustee/Custodian or any successor trustee/custodian
         may be transferred, shall be the successor of such Trustee/Custodian
         without the filing of any instrument or performance of any further
         act, before any court.

15.6     RESIGNATION AND REMOVAL  The Trustee/Custodian may resign by written
notice to the Employer which shall be effective 60 days after delivery.  The
Employer may discontinue its participation in this Prototype Plan and
Trust/Custodial Account effective upon 60 days written notice to the Sponsor.
In such event the Employer shall, prior to the effective date thereof, amend
the Plan to eliminate any reference to this Prototype Plan and Trust/Custodial
Account and appoint a successor trustee or custodian or arrange for another
funding agent.  The Trustee/Custodian shall deliver the Fund to its successor
on the effective date of the resignation or removal, or as soon thereafter as
practicable, provided that this shall not waive any lien the Trustee/Custodian
may have upon the Fund for its compensation or expenses.  If the Employer fails
to amend the Plan and appoint a successor trustee, custodian, or other funding
agent within the said 60 days, or such longer period as the Trustee/Custodian
may specify in writing, the Plan shall be deemed individually designed and the
Employer deemed the successor trustee/custodian.  The Employer must then obtain
its own determination letter.

15.7     QUALIFICATION OF PROTOTYPE  The Sponsor intends that this Prototype
Plan will meet the requirements of the Code as a qualified Prototype Retirement
Plan and Trust/Custodial Account.  Should the Commissioner of Internal Revenue
or any delegate of the Commissioner at any time determine that the Plan and
Trust/Custodial Account fails to meet the requirements of the Code, the Sponsor
will amend the Plan and Trust/Custodial Account to maintain its qualified
status.


                                  ARTICLE XVI

                                 GOVERNING LAW


Construction, validity and administration of the Prototype Plan and
Trust/Custodial Account, and any Employer Plan and Trust/Custodial Account as
embodied in the Prototype document and accompanying Adoption Agreement, shall
be governed by Federal law to the extent applicable and to the extent not
applicable by the laws of the State/Commonwealth in which the principal
<PAGE>   81
office of the Sponsor or its affiliate which is designated as Trustee or
Custodian in the Adoption Agreement, is located.

                              MODEL PLAN AMENDMENT
                            REVENUE PROCEDURE 93-47

(This model amendment allows Participants receiving distributions from
safe-harbored profit sharing plans to waive the 30-day period required under
the Unemployment Compensation Act of 1992.  Non-safe harbored plans must still
provide notice not less than 30 days and not more than 90 days prior to the
distribution.)

If a distribution is one to which Sections 401(a)(11) and 417 of the Internal
Revenue Code do not apply, such distribution may commence less than 30 days
after the notice required under Section 1.411(a)-11(c) of the Income Tax
Regulations is given, provided that:

         (1)     the plan administrator clearly informs the Participant that
                 the Participant has a right to a period of at least 30 days
                 after receiving the notice to consider the decision of whether
                 or not to elect a distribution (and, if applicable, a
                 particular distribution option), and

         (2)     the Participant, after receiving the notice, affirmatively
                 elects a distribution.



                              MODEL PLAN AMENDMENT
                       CODE SECTION 401(a)(17) LIMITATION

In addition to other applicable limitations set forth in the Plan, and
notwithstanding any other provision of the Plan to the contrary, for Plan Years
beginning on or after January 1, 1994, the annual Compensation of each Employee
taken into account under the Plan shall not exceed the OBRA'93 annual
compensation limit.  The OBRA '93 annual compensation limit is $150,000, as
adjusted by the Commissioner for increases in the cost of living in accordance
with Section 401(a)(17)(B) of the Internal Revenue Code.  The cost-of- living
in effect for a calendar year applies to any period, not exceeding 12 months,
over which Compensation is determined (determination period) beginning in such
calendar year. If a determination period consists of fewer than 12 months, the
OBRA '93 annual compensation limit will be multiplied by a fraction, the
numerator of which is the number of months in the determination period, and the
denominator of which is 12.

For Plan Years beginning on or after January 1, 1994, any reference in this
Plan to the limitation under Section 401(a)(17) of the Code shall mean the OBRA
'93 annual compensation limit set forth in this provision.

If Compensation for any prior determination period is taken into account in
determining an Employee's benefits accruing in the current Plan Year, the
Compensation for that prior determination period is subject to the OBRA '93
annual compensation limit in effect for that prior determination period.  For
this purpose, for determination periods beginning before the first day of the
first Plan Year beginning on or after January 1, 1994, the OBRA '93 annual
compensation limit is $150,000.
