         None

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Subsection (a) of Section 145 of the General Corporation Law of the
State of Delaware empowers a corporation to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another


                                        1

<PAGE>   3



corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

         Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, except that no indemnification may be made in
respect of any claim, issue or matter as to which such person shall have been
made to be liable to the corporation unless and only to the extent that the
Court of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         Section 145 further provides that to the extent a director or officer
of a corporation has been successful on the merits or otherwise in the defense
of any action, suit or proceeding referred to in subsections (a) and (b) of
Section 145 in the defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith; that indemnification provided for by
Section 145 shall not be deemed exclusive of any other rights to which the
indemnified party may be entitled; that indemnification provided for by Section
145 shall, unless otherwise provided when authorized or ratified, continue as to
a person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of such person's heirs, executors and administrators; and
empowers the corporation to purchase and maintain insurance on behalf of a
director or officer of the corporation against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such whether or not the corporation would have the power to indemnify him
against such liabilities under Section 145.

         Section 102(b)(7) of the General Corporation Law of the State of
Delaware provides that a certificate of incorporation may contain a provision
eliminating or limiting the personal liability of a director to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director provided that such provision shall not eliminate or limit the liability
of a director (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.

         Article Seventh of the Company's Third Restated Certificate of
Incorporation, as amended, states that:

         No director shall be personally liable to the Corporation or its
         stockholders for monetary damages for any breach of fiduciary duty by
         such director as a director. Notwithstanding the foregoing sentence, a
         director shall be liable to the extent provided by applicable law (i)
         for any breach of the director's duty of loyalty to the Corporation or
         its stockholders, (ii) for acts or omissions not in good faith or which
         involve intentional misconduct or a knowing violation of law, (iii)
         pursuant to section 174 of the GCL or (iv) for any transaction from
         which the director derived an improper personal benefit.

         In addition, Section 8 of the Company's Bylaws, further provide that
the Company shall indemnify its officers, directors and employees to the fullest
extent permitted by law.

ITEM 9.  UNDERTAKINGS

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:


                                      3

<PAGE>   5


                           (i)  To include any prospectus required by Section 
         10(a)(3) of the Securities Act of 1933;

                           (ii) To reflect in the prospectus any facts or events
         arising after the effective date of the registration statement (or the
         most recent post-effective amendment thereof) which, individually or in
         the aggregate, represent a fundamental change in the information set
         forth in the registration statement; notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement;

                           (iii) To include any material information with
         respect to the plan of distribution not previously disclosed in the
         registration statement or any material change to such information in
         the registration statement.

         Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
the registration statement is on Form S-3, Form S-8 or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described in Item 6 of this
Registration Statement, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1993 and will be governed by the
final adjudication of such issue.

                      SAVINGS PLAN FOR SALARIED EMPLOYEES

       Pioneer Chlor Alkali Company, Inc. hereby amends, renames, and restates
the Pioneer Chlor Alkali Company, Inc. Savings Investment Plan and Trust
effective as of July 1, 1998, unless provided otherwise herein.  The terms and
provisions of the Plan as so amended are as follows:

                                  INTRODUCTION

       The purposes of this Plan are to provide benefits for eligible Employees
through an Employer profit sharing contribution and to promote and encourage
Employees to provide additional security and income for their retirement
through a systematic matching savings program.  However, the establishment of
this Plan shall not be considered as giving any Employee or any other person
any legal or equitable right as against any Employer, the Committee or the
Trustee, or in the assets of the Plan, except and to the extent that such right
is specifically provided for in this Plan.

       This Plan has been adopted for the exclusive benefit of the Members and
their beneficiaries.  So far as possible, this Plan shall be interpreted in a
manner consistent with this intent and with the intention of the Corporation
that this Plan shall satisfy those provisions of ERISA and the Code relating to
qualified employee profit sharing plans with a Code Section 401(k) feature.

       The Plan is hereby amended and completely restated as set forth herein
and all rights and benefits under the Plan shall hereafter be determined under
the terms and provisions hereof.  However, the amendment and restatement of the
Plan hereby shall not operate or be construed to deprive any Member of any
protected benefit, within the meaning of Code Section 411(d)(6) and the
regulations thereunder, he may have had under the Plan as in effect immediately
prior to this amendment.

                               TACOMA PLAN MERGER

       Effective as of July 1, 1998, the Pioneer Tacoma Salaried 401(k) Plan
(the "Tacoma Plan") was merged into the Plan, as provided in the Merger
Agreement dated June __, 1998.

          CHANGE IN INVESTMENT FUNDS -- RECORDKEEPING TRANSITION PERIOD

       Notwithstanding anything in the Plan to the contrary, in order to
transfer the recordkeeping of the Plan's "old" investment funds to the "new"
investment funds, an Implementation Period (beginning July 1, 1998 and
estimated to last approximately three months) will apply to all Members, other
than members of the Tacoma Plan merged into the Plan or to employees who join
the Plan after July 1, 1998.  During the Implementation Period, affected
Members will not be able to change the investment of their current
contributions or account balances.  Investment elections as in effect on June
30, 1998 will be temporarily "frozen" and "mapped" into new investment funds
<PAGE>   8
as described in the Company's memorandum to all participants dated May 28,
1998.  In addition, withdrawals or loans may not be made during the
Implementation Period.

                                   ARTICLE I
                                  DEFINITIONS

       The following words and phrases as used herein shall have the following
meanings unless a different meaning is plainly required by the context:

1.1    ACCOUNT OR ACCOUNTS:  The Employer Contribution Account, the Savings
Contribution Account, the Salary Deferral Contribution Account and/or the
Rollover Account of a Member.

1.2    ACTUAL DEFERRAL PERCENTAGE:  The Actual Deferral Percentage, as defined
in Section 4.6.

1.3    AFFILIATED COMPANY:  Any corporation which is a member of a controlled
group of corporations (within the meaning of the Code Section 414(b)) with the
Corporation; any trade or business (whether or not incorporated) which is under
common control (as defined in Code Section 414(c)) with the Corporation; any
organization (whether or not incorporated) which is a member of an affiliated
service group (as defined in Code Section 414(m)) which includes the
Corporation; and any other entity required to be aggregated with the
Corporation pursuant to Regulations under Code Section 414(o).  For purposes of
applying the limitations of Code Section 415, an Affiliated Company shall be
determined in accordance with Code Section 415(h).

1.4    AGGREGATION GROUP:  For purposes of Article XVI, the group of plans, if
any, that includes both the group of plans required to be aggregated and the
group of plans permitted to be aggregated.  The group of plans required to be
aggregated (the "required aggregation group") includes:

              (a)    Each plan of an Affiliated Company in which a Key Employee
       is a participant, including collectively bargained plans, and

              (b)    Each other plan, including collectively bargained plans,
       of an Affiliated Company which enables a plan in which a Key Employee is
       a participant to meet the requirements of the Code, as amended,
       prohibiting discrimination as to contributions or benefits in favor of
       employees who are officers, shareholders, or the highly compensated or
       prescribing minimum participation standards.

       The group of plans that are permitted to be aggregated (the "permissive
aggregation group") includes the required aggregation group plus one or more
plans of an Affiliated Company that is not part of the required aggregation
group, and that the Affiliated Company certifies as a plan within the
permissive aggregation group.  Such plan or plans may be added to the
permissive aggregation group only if, after the addition, the aggregation group
as a whole continues not to discriminate as to contributions or benefits in
favor of officers, shareholders, or the highly compensated, and to meet the
minimum participation standards under the Code.




                                       I-1
<PAGE>   10
1.5    ANNUAL ADDITIONS:  With respect to each Plan Year, the total of Employer
contributions (including Salary Deferral Contributions), forfeitures and Member
contributions allocated to a Member's Account for such Plan Year.  Amounts
allocated to an individual medical account, as defined in Code Section 415(1),
which is part of a defined benefit plan maintained by the Employer, are treated
as Annual Additions.  Also, amounts derived from contributions which are
attributable to post-retirement medical benefits allocated to the separate
account of a key employee, as defined in Code Section 419A(d)(3), under a
welfare benefit fund, as defined in Code Section 419(e), maintained by the
Employer, are treated as Annual Additions.

1.6    ANNUAL BENEFIT:  Means a benefit payable annually in the form of a
straight life annuity (with no ancillary benefits) under a plan, but excluding
benefits attributable to Employee contributions and rollover contributions.

1.7    APPLICABLE COMPENSATION:  For purposes of Code Section 415, Applicable
Compensation means (i) a Member'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 and also without regard to salary deferral
elections pursuant to Code Sections 125 or 401(k)) for personal services
actually rendered in the course of employment with the Employer or Affiliated
Company maintaining the Plan to the extent that the amounts are includable in
gross income (including, but not limited to, commissions paid salesmen,
compensation for services on the basis of the percentage of profits,
commissions on insurance premiums, tips, bonuses, fringe benefits,
reimbursements and expense allowances), (ii) amounts described in Code Sections
104(a)(3), 105(a) and 105(h), but only to the extent that these amounts are
includable in the gross income of the Employee, (iii) amounts paid or
reimbursed by the Employer or Affiliated Company for moving expenses incurred
by the Employee, but only to the extent that these amounts are excludable from
gross income of the Employee, (iv) the value of a nonqualified stock option
granted to an Employee, but only to the extent such value is included in the
gross income of the employee for the taxable year in which granted, and (v) the
amount included in the gross income of the Employee upon making the election
under Code Section 83(b), but excluding the following:

              (a)    Contributions made by the Employer or Affiliated Company
       to a plan of a deferred compensation to the extent that, before the
       application of the Code Section 415 limitations to that plan, the
       contributions are not includable in the gross income of the Employee for
       the taxable year in which contributed.  In addition, Employer
       contributions made on behalf of an Employee to a simplified employee
       pension described in Code Section 408(k) are not considered as
       compensation for the taxable year in which contributed to the extent
       such contributions are deductible by the Employee under Code Section
       219(b)(7).  Additionally, any distributions from a plan of deferred
       compensation are not considered as compensation for Code Section 415
       purposes, regardless of whether such amounts are includable in the gross
       income of the Employee when distributed.  However, any amounts received
       by an Employee pursuant to an unfunded non-qualified plan may be
       considered as compensation for Code Section 415 purposes in the year
       such amounts are includable in the gross income of the Employee.



                                       I-2
<PAGE>   11
              (b)    Amounts realized from the exercise of a non-qualified
       stock option, or when restricted stock (or property) held by an Employee
       becomes freely transferable or is no longer subject to a substantial
       risk of forfeiture (see Code Section 83 and the regulations thereunder).

              (c)    Amounts realized from the sale, exchange or other
       disposition of stock acquired under a qualified stock option.

              (d)    Other amounts which receive special tax benefits, such as
       premiums for group term life insurance (but only to the extent that the
       premiums are not includable in the gross income of the Employee), or
       contributions made by an Employer or Affiliated Company (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 excludable from the gross income of the Employee).

Subject to the foregoing exclusions, for purposes of applying the limitations
above, amounts included as Applicable Compensation are those actually paid or
made available to a Member within the Plan Year.

1.9    BREAK IN SERVICE:  A calendar year during which the Employee is credited

for periods of absence from work (1) by reason of the pregnancy of the
Employee, (2) by reason of the birth of a child of the Employee, (3) by reason
of the placement of a child in connection with the adoption of the child by the
Employee, or (4) for purposes of caring for the child during the period
immediately following the birth or placement for adoption.  During the period
of such absence, the Employee shall be treated as having completed (1) the
number of Hours of Service that normally would have been credited but for the
absence, or (2) if the normal Hours of Service worked are unknown, eight Hours
of Service for each normal workday during the absence.  The total number of
Hours of Service required to be treated as completed for any such period of
absence shall not exceed 501 hours for those Hours of Service shall be credited
only (1) in the year in which the absence begins for one of the permitted
reasons, if the crediting is necessary to prevent a Break in Service in that
year, or (2) in the following year.

                                       I-3

       but excluding all other items of compensation.  However, annual
       compensation in excess of $160,000 (as such amount shall be adjusted as
       permitted under Code Section 401(a)(17)) shall be disregarded for
       purposes of this Plan.  For any Plan Year of less than 12 months, the
       applicable dollar limit for such year shall be prorated by dividing the
       number of full months in such year by 12.

1.14   CORPORATION:  Pioneer Chlor Alkali Company, Inc., a Delaware
corporation.

1.15   DETERMINATION DATE:  For purposes of any Plan Year, the last day of the
immediately preceding Plan Year.

1.16   EFFECTIVE DATE OF THE PLAN:  October 25, 1988.

1.17   ELIGIBLE CLASS:  An Employee of an Employer who is not (1) a Leased
Employee, (2) a member of, or covered by, a collective bargaining unit which

for the participation of such Employees in the Plan, or (3) a nonresident alien
with no U.S. source income.

1.18   EMPLOYEE:  Any employee of the Corporation or an Affiliated Company and,
to the extent required to be treated as an "employee" for certain Plan purposes
by Code Section 414, any Leased Employee performing services for the
Corporation or an Affiliated Company.  It shall also include, with respect to
an Employer, an employee or former employee who is receiving severance under a
plan, program or agreement of the Employer, to the extent severance is
permitted by applicable regulations under Code Section 401(a)(4) to be treated
as imputed service, but such imputed employment shall not exceed two years.

Companies as from time to time is participating in the Plan, as provided in
Article XV.

1.20   EMPLOYER CONTRIBUTION:  The Employer's matching contributions to the

record his share of the matching contributions of the Employer, the investment
thereof and adjustments relating thereto.

1.22   ERISA:  The Employee Retirement Income Security Act of 1974, as amended,

                                       I-4
<PAGE>   13
1.24   EXCESS CONTRIBUTIONS:  Amounts exceeding the Actual Deferral Percentage
limits for Highly Compensated Employees.

1.25   HIGHLY COMPENSATED EMPLOYEE:  Any Employee or former Employee who is a
highly compensated employee as defined in Code Section 414(q).  Generally, any
Employee or former Employee is considered a Highly Compensated Employee if
during the Plan Year or the preceding Plan Year such Employee or former
Employee:

              (a)    was at any time a "5% owner."  "5% owner" means any person
       who owns (or is considered as owning within the meaning of Code Section
       318) more than 5% of the outstanding stock of the Employer or stock
       possessing more than 5% of the total combined voting power of all stock
       of the Employer or, in the case of an unincorporated business, any
       person who owns more than 5% of the capital or profits interest in the
       Employer.  In determining percentage ownership hereunder, Affiliated
       Companies that would otherwise be aggregated under Code Section 414(b),
       (c), and (m) shall be treated as separate Employers.

              (b)    received Total Compensation from the Employer in excess of
       $80,000 (as adjusted by Code Section 415(d)), and

              (c)    if elected by the Corporation for such preceding year, was
       in the top 20% of the Employees when ranked on the basis of Applicable
       Compensation paid during the previous year.

For purposes of determining whether an Employee is a Highly Compensated
Employee for the Plan Year beginning in 1997, the above definition shall be
treated as having been in effect for the Plan Year beginning in 1996.

1.26   HOUR OF SERVICE:  Each hour for which an Employee is paid, or entitled
to payment, for the performance of duties for the Employer or an Affiliated
Company during the applicable computation period.  An Hour of Service is each
hour for which an Employee is paid, or entitled to payment by the Employer or
an Affiliated Company on account of a period of time during which no duties are
performed, due to vacation, holiday, illness, incapacity (including
disability), layoff, jury duty, military duty or leave of absence.  No more
than 501 hours shall be credited with respect to any single continuous period
during which the Employee performs no duties (whether or not such period occurs
in a single computation period).  An hour for which an Employee is directly or
indirectly paid, or entitled to payment, on account of a period during which no
duties are performed is not required to be credited to the Employee if such
payment is made or due under a plan maintained solely for the purpose of
complying with applicable workmen's compensation, or unemployment compensation
or disability insurance laws; and Hours of Service are not required to be
credited for a payment which solely reimburses an Employee for medically
related expenses incurred by the Employee.  For purposes of this section, a
payment shall be deemed to be made by or due from an Employer regardless of
whether such payment is made by or due from the Employer directly or



                                       I-5
<PAGE>   14
indirectly, through, among others, a trust fund or insurer or other entity to
which the Employer contributes or pays premiums and regardless of whether
contributions made or due to the trust fund, insurer or other entity are for
the benefit of particular employees or on behalf of a group of employees in the
aggregate.  An Hour of Service is also 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 in two periods.
Crediting of Hours of Service for back pay awarded or agreed to shall be with
respect to the periods within which such service was performed.  For purposes
of determining whether a Break in Service has occurred, an Employee shall be
deemed to have completed Hours of Service for periods of absence from work (1)
by reason of the pregnancy of the Employee, (2) by reason of the birth of a
child of the Employee, (3) by reason of the placement of a child in connection
with the adoption of the child by the Employee, or (4) for purposes of caring
for the child during the period immediately following the birth or placement
for adoption.  During the period of such absence, the Employee shall be treated
as having completed (1) the number of Hours of Service that normally would have
been credited but for the absence, or (2) if the normal Hours of Service worked
are unknown, eight Hours of Service for each normal workday during the absence.
The total number of Hours of Service required to be treated as having been
completed for any such period of absence shall not exceed 501 hours.  Further,
such Hours of Service shall be credited only (1) in the year which the absence
begins for one of the permitted reasons, if the crediting is necessary to
prevent a Break in Service in that year, or (2) in the following year.  Hours
of Service shall be credited to computation periods in accordance with the
provisions of Department of Labor Regulation Section 2530.200b.  Instead of
counting and crediting actual hours worked, for purposes of determining the
number of Hours of Service to be credited to an Employee, an Employee may be
credited with 190 Hours of Service for each calendar month during which he has
earned one Hour of Service.  For purposes of determining the number of Hours of
Service to be credited for reasons other than the performance of duties and for
purposes of determining to which computation period Hours of Service earned

       made until the $30,000 limit is 25% of the defined benefit limit.  The
       two limits will then rise in tandem, with the defined contribution limit
       set at 1/4 of the defined benefit limit.  Such adjustments to the limits
       will be based on cost-of-living adjustments in the CPI, or

excluding former Key Employees as provided in Section 16.6(d), under all such
defined benefit plans, plus the aggregate accounts for all employees, excluding
former Key Employees as provided in Section 16.6(d), under all such defined

performed any services for any Employer or Affiliated Company at any time
during the five-year period ending on the Determination Date, any accrued
benefit for such individual, and the aggregate accounts of such individual
shall not be taken into account.  If the Aggregation Group that is a Top-Heavy
Group is a required aggregation group, each plan in the group will be a Top-
Heavy Plan (as defined in Section 16.6).  If the Aggregation Group that is a
Top-Heavy Group is a permissive aggregation group, only those plans that are

                                  ELIGIBILITY

3.1    EMPLOYEES ELIGIBLE:  Only Employees who are in the Eligible Class shall
be eligible to actively participate in the Plan, and each such Employee shall
be eligible to make Savings Contributions and/or Salary Deferral Contributions
to the Plan beginning on the first day of the month coincident with or next
following the date on which he first completes an Hour of Service; provided,
however, (1) former Employees who are in the Eligible Class upon the date of
their rehire shall be eligible to participate immediately and (2) Employees who
are in the Eligible Class shall be eligible to make qualifying rollover
contributions to the Plan at any time.  The date an Employee in the Eligible
Class is first eligible to contribute to the Plan (other than a rollover
contribution) and the first day of each month thereafter that he remains
eligible to join the Plan is the "entry date."

3.2    SAVINGS CONTRIBUTION OR SALARY DEFERRAL CONTRIBUTION AUTHORIZATION
REQUIRED:  An Employee in the Eligible Class may become a Member of the Plan on
any future entry date by authorizing a Savings Contribution and/or a Salary
Deferral Contribution and directing the investment thereof in the manner
hereinafter provided.

3.3    CONTRIBUTIONS VOLUNTARY: Contributions to the Plan by an Employee are
entirely voluntary.

3.4    TRANSFERS OF EMPLOYMENT:  Transfers of employment between two or more
Employers shall not affect a Employee's membership in the Plan, except as
provided in this Section 3.4.  Any transfer of a Member to employment with a
non-participating Affiliated Company or to an employment classification that is
not in the Eligible Class shall not constitute a termination of service.  Each
such transferred Member shall remain a Member of the Plan and shall retain the
rights and benefits accrued under the Plan prior to the date of such transfer
until his subsequent retirement, termination of service or total withdrawal.
However, each such transferred Member shall not be eligible to make additional
Savings Contributions or Salary Deferral Contributions while he is employed by
a non-participating Affiliated Company or while he is not employed in the
Eligible Class.

                           CONTRIBUTIONS AND VESTING

4.1    SAVINGS CONTRIBUTIONS:  An Employee in the Eligible Class may authorize
a Savings Contribution, to be effected by payroll deductions, in whole
percentages of not less than 1% and not more than 15% of his Compensation for
such payroll period, subject to Section 4.2.

4.2    SALARY DEFERRAL CONTRIBUTIONS:  Subject to Section 4.8, an Employee in
the Eligible Class may elect a Salary Deferral Contribution rate (in whole
percentages) of not less than 1% and not more than 15% of his Compensation for
any payroll period, to be effected by payroll reductions.  Each such election
of a Salary Deferral Contribution rate shall be made in writing on a salary
reduction election form provided by the Committee at least ten days prior to
the effective date of such election (if not made as of the date service
commences), shall be subject to reduction as provided in Section 4.8, and shall
be subject to such other terms and conditions as the Committee may determine.
The sum of an Employee's Salary Deferral Contribution rate and Savings
Contribution rate may not exceed 15% and, to the extent necessary, a Member's
Savings Contributions shall be reduced first.

              (a)    A Member's Salary Deferral Contribution made pursuant to
       this Section shall not exceed $10,000 for the taxable year of the
       Member.  This dollar limitation shall be adjusted annually as provided
       in Code Section 415(d) pursuant to Regulations.  The adjusted limitation
       shall be effective as of January 1 of each calendar year.

              (b)    In the event that the dollar limitation provided for in
       Section 4.2(a) is exceeded, the Committee shall direct the Trustee to
       either (1) distribute such excess amount, and any income (or loss)
       allocable to such amount (as provided in (d) below), to the Member not
       later than the first April 15 following the close of the Member's
       taxable year or (2) to recharacterize such excess amount, and any income
       or (loss) allocable to such amount, as a Savings Contributions made by
       the Member, subject to the further provisions of the Plan applicable to
       Savings Contributions.

              (c)    In the event that a Member is also a participant in (1)
       another qualified cash or deferred arrangement (as defined in Code
       Section 401(k)), (2) a simplified employee pension (as defined in Code
       Section 408(k)), or (3) a salary reduction arrangement (within the
       meaning of Code Section 3121(a)(5)(D)) and the elective deferrals, as
       defined in Code Section 402(g)(3), made under such other arrangement(s)
       and this Plan cumulatively exceed $10,000 (or such amount adjusted
       annually as provided in Code Section 415(d) pursuant to Regulations) for
       such Member's taxable year, the Member may, not later than March 1
       following the close of his taxable year, notify the Committee in writing
       of such excess and request that his Salary Deferral Contribution under
       this Plan be reduced by an amount specified by the Member.  Such amount
       shall then be distributed in the same manner as provided in Section
       4.2(b).



                                       IV-1
<PAGE>   21
              (d)    The income (or loss) allocable to returnable contributions
       shall equal the sum of the allocable gain or loss for the Plan Year and
       the allocable gain or loss for the period between the end of the Plan
       Year and the date of distribution.  Income includes all earnings and
       appreciation, including such items as interest, dividends, rent,
       royalties, gains from the sale of property, appreciation in the value of
       stocks, bonds, annuity and life insurance contracts, and other property,
       without regard to whether such appreciation has been realized.

                     (1)    The income (or loss) allocable to returnable
              contributions for the Plan Year is determined by multiplying the
              income (or loss) for the Plan Year allocable to employee
              contributions, matching contributions, and amounts treated as
              matching contributions (whichever is applicable) by a fraction.
              The numerator of the fraction is the amount of returnable
              contributions made on behalf of the employee for the Plan Year.
              The denominator of the fraction is the total account balance of
              the employee attributable to employee contributions, matching
              contributions and amounts treated as matching contributions as of
              the end of the Plan Year, reduced by the gain allocable to such
              total amount for the Plan Year and increased by the loss
              allocable to such total amount for the Plan Year.

                     (2)    The allocable income or loss for the period between
              the end of the Plan Year and the distribution date is equal to 10
              percent of the income or loss allocable to returnable
              contributions for the Plan Year (as calculated under subparagraph
              (1) above) multiplied by the number of calendar months that have
              elapsed since the end of the Plan Year.  For purposes of
              determining the number of calendar months that have elapsed, a
              distribution occurring on or before the fifteenth day of the
              month will be treated as having been made on the last day of the
              preceding month, and a distribution occurring after such
              fifteenth day will be treated as having been made on the first
              day of the next month.

4.3    MATCHING EMPLOYER CONTRIBUTIONS:  Subject to the other provisions of the
Plan, with respect to each payroll period the Employers shall contribute, with
respect to each Member who made Savings Contributions and/or Salary Deferral
Contributions for such pay period, an amount equal to 50% of the sum of the
Member's Savings Contributions and Salary Deferral Contributions for that
payroll period, but only to the extent the sum of such contributions does not
exceed 6% of the Member's Compensation for the applicable payroll period;
provided that, if a Member has made both Savings Contributions and Salary
Deferral Contributions, the Employer Contributions shall be deemed to have been
made first with respect to the Salary Deferral Contributions.

4.4    CHANGE IN CONTRIBUTION RATE:  The Savings Contribution and/or Salary
Deferral Contribution rate elected by a Member may be changed by a Member, upon
advance notice, as of the first day of any calendar quarter following proper
notice, but any such change shall not be retroactive.



                                       IV-2
<PAGE>   22
4.5    VOLUNTARY SUSPENSION OF CONTRIBUTIONS:  A Member who has elected to
contribute and/or defer a portion of his Compensation as a Savings Contribution
and/or Salary Deferral Contribution under the Plan may suspend any further
contributions and/or deferrals as of the end of any payroll period if, and only
if prior to the end of such payroll period, he gives notice to his Employer, in
such form and manner as the Committee may prescribe, of his election to effect
such suspension.  Such suspension shall remain in effect until the Member again
properly elects to make contributions to the Plan.

4.6    ACTUAL DEFERRAL PERCENTAGE:  For the purposes of this Section, "Actual
Deferral Percentage" means, with respect to the Highly Compensated Employee
group and Non-Highly Compensated Employee group for a Plan Year, the average of
the ratios, calculated separately for each Member in such group, of the amount
of Salary Deferral Contributions allocated to each Member's Salary Deferral
Contribution Account (unreduced by distributions made pursuant to Sections
4.2(b) and 4.2(d)) for such Plan Year, to such Member's Total Compensation for
such Plan Year.

4.7    ACTUAL DEFERRAL PERCENTAGE TEST:

              (a)    Maximum Annual Allocation: For each Plan Year, the annual
       allocation derived from Salary Deferral Contributions to a Member's
       Salary Deferral Contribution Account shall satisfy one of the following
       tests:

                     (1)    The "Actual Deferral Percentage" for the Highly
              Compensated Employee group shall not be more than the "Actual
              Deferral Percentage" of the Non-Highly Compensated Employee group
              multiplied by 1.25, or

                     (2)    The excess of the "Actual Deferral Percentage" for
              the Highly Compensated Employee group over the "Actual Deferral
              Percentage" for the Non-Highly Compensated Employee group shall
              not be more than two percentage points.  Additionally, the
              "Actual Deferral Percentage" for the Highly Compensated Employee
              group shall not exceed the "Actual Deferral Percentage" for the
              Non-Highly Compensated Employee group multiplied by two.  This
              alternative limitation test cannot be used to satisfy the Actual
              Deferral Percentage test and the Contribution Percentage Test of
              Section 4.9, except as otherwise provided by applicable
              regulations.

              (b)    For the purposes of  Sections 4.7(a) and 4.8, a Highly
       Compensated Employee and a Non-Highly Compensated Employee shall include
       any Employee eligible to make a deferral election pursuant to Section
       4.2, whether or not such deferral election was made.

              (c)    For the purposes of this Section, if two or more plans
       which include cash or deferred arrangements are considered one plan for
       the purposes of Code Section 401(a)(4) or 410(b), the cash or deferred
       arrangements included in such plans shall be treated as one arrangement.



                                       IV-3
<PAGE>   23
              (d)    For the purposes of this Section, if a Highly Compensated
       Employee is a Member under two or more cash or deferred arrangements of
       the Employer, all such cash or deferred arrangements shall be treated as
       one cash or deferred arrangement for the purpose of determining the
       deferral percentage with respect to such Highly Compensated Employee.

              (e)    Notwithstanding the above, the determination and treatment
       of Employer Salary Deferral Contributions and "Actual Deferral
       Percentage" of any Member shall satisfy such other requirements as may
       be prescribed by the Secretary of the Treasury.

4.8    ADJUSTMENTS AS A RESULT OF ACTUAL DEFERRAL PERCENTAGE TEST:  In the
event that the initial allocations of the Salary Deferral Contributions made
pursuant to the Plan do not satisfy one of the tests set forth in Section
4.7(a), either of the following actions shall be taken:

              (a)    On or before the 15th day of the third month following the
       end of each Plan Year, but in no event later than the close of the
       following Plan Year, the Committee shall direct the Trustee to
       distribute to the Highly Compensated Employee group the aggregate amount
       of excess Salary Deferral Contributions (and any income allocable to
       such contributions as provided in (d) of Section 4.2), beginning with
       the Member(s) having the highest dollar amount of Salary Deferral
       Contributions, reducing such Members' contributions pro rata to the next
       highest dollar amount of Salary Deferral Contributions (and continuing
       with the next highest group and so on) until the aggregate excess amount
       is distributed.

              (b)    Within 30 days after the end of the Plan Year, the
       Employer shall make a contribution on behalf of Non-Highly Compensated
       Employees in an amount sufficient to satisfy one of the tests set forth
       in Section 4.7(a).  Such contribution shall be deemed a Salary Deferral
       Contribution and allocated to the Salary Deferral Contribution Account
       of each Non-Highly Compensated Employee in the same proportion that each
       Non-Highly Compensated Employee's Salary Deferral Contribution for the
       year bears to the total Salary Deferral Contributions of all Non-Highly
       Compensated Employees.  However, if option (b) is elected, then in all
       events such contributions shall be fully vested when made and shall be
       subject to the same distribution restrictions that apply to Salary
       Deferral Contributions, except that such amounts may not be withdrawn
       prior to the Member's termination of employment.

              (c)    The amount of excess Salary Deferral Contributions to be
       distributed or recharacterized shall be reduced by excess deferrals
       previously distributed for the taxable year ending in the same Plan Year
       and excess deferrals to be distributed for a taxable year will be
       reduced by excess contributions previously distributed or
       recharacterized for the Plan beginning in such taxable year.

4.9    MAXIMUM CONTRIBUTION PERCENTAGE.

              (a)    The "Contribution Percentage" for the Highly Compensated
       Employee group shall not exceed the greater of:

                     (1)    125% of such percentage for the Non-Highly
              Compensated Employee group; or

                     (2)    the lesser of 200% of such percentage for the Non-
              Highly Compensated Employee group, or such percentage for the
              Non-Highly Compensated Employee group plus two percentage points
              or such lesser amount determined pursuant to Regulations to
              prevent the multiple use of this alternative limitation with
              respect to any Highly Compensated Employee.

              (b)    For the purposes of this Section and Section 4.10,
       "Contribution Percentage" for a Plan Year means, with respect to the
       Highly Compensated Employee group and Non-Highly Compensated Employee
       group, the average of the ratios (calculated separately for each Member
       in each group) of:

                     (1)    the sum of the matching contributions pursuant to
              Section 4.3 and Employee Savings Contributions pursuant to
              Section 4.1 contributed under the Plan on behalf of each such
              Member for such Plan Year; to

                     (2)    the Member's Total Compensation for such Plan Year.

              (c)    The "Contribution Percentage" for a Highly Compensated
       Employee shall be determined by including matching contributions
       pursuant to Section 4.3 and Employee Savings Contributions pursuant to
       Section 4.1.

              (d)    For purposes of this Section, if two or more plans of the
       Employer to which matching contributions, Employee contributions, or
       elective deferrals are made are treated as one plan for purposes of Code
       Section 410(b), such plans shall be treated as one plan for purposes of
       this Section 4.9.  In addition, if a Highly Compensated Employee
       participates in two or more plans described in Code Section 401(a) or
       arrangements described in Code Section 401(k) which are maintained by
       the Employer to which such contributions are made, all such
       contributions shall be aggregated for purposes of this Section 4.9.

              (e)    For purposes of Section 4.9(a) and 4.10, a Highly
       Compensated Employee and Non-Highly Compensated Employee shall include
       any Employee eligible to have matching contributions pursuant to Section
       4.3 and Employee Savings Contributions pursuant to Section 4.1 allocated
       to his account for the Plan Year.

4.10   ADJUSTMENTS FOR EXCESSIVE CONTRIBUTION PERCENTAGE:

              (a)    In the event that the "Contribution Percentage" for the
       Highly Compensated Employee group exceeds the "Contribution Percentage"
       for the Non-Highly Compensated Employee group pursuant to Section
       4.9(a), the Committee (on or before the 15th day of the third month
       following the end of the Plan Year, but in no event later than the close
       of the following Plan Year) the Committee shall direct the Trustee to
       distribute to the Highly Compensated Employee group the amount of
       "Excess Aggregate Contributions" (and any income allocable to such
       contributions as provided in (d) of Section 4.2), beginning with the
       Member(s) with the highest dollar amount of such contributions, reducing
       such Members' contributions pro rata to the next highest dollar amount
       of contributions (and continuing with the next highest group and so on)
       until the aggregate amount of such excess is distributed.  However, no
       forfeiture may be allocated to a Highly Compensated Employee whose
       contributions are reduced pursuant to this Section.

              (b)    The determination of the amount of "Excess Aggregate
       Contributions" with respect to any Plan Year shall be made after:

                     (1)    first determining the excess contributions pursuant
              to Section 4.2(a), and

                     (2)    then determining the excess annual allocations
              pursuant to Section 4.7(a).

              (c)    To prevent the multiple use of the alternative methods of
       compliance with the ADP test and the ACP test, the provision of section
       1.401(m)-2 of the regulations are hereby incorporated by reference to
       determine if such multiple use exists.  If, after application of such
       test, multiple use exists, the actual contribution percentage shall be
       reduced as provided in section 1.401(m)-2(c) of the regulations for all
       Highly Compensated Employees in the Plan.

              (d)    Notwithstanding anything in the Plan to the contrary, an
       employer matching contribution may be distributed only if such
       contribution is an excess aggregate contribution.  It may not be
       distributed merely because it relates to an excess deferral, an excess
       contribution or an excess aggregate contribution that is distributed.
       In such cases, the related matching contribution shall be forfeited
       notwithstanding anything in the Plan to the contrary.

4.11   MAXIMUM ANNUAL ADDITIONS:  Notwithstanding anything contained herein to
the contrary, the total Annual Additions made to Accounts of a Member for any
Plan Year shall be subject to the following limitations:



                                       IV-6
<PAGE>   26
       (a)    Single Defined Contribution Plan

                     (1)    If an Employer does not maintain any other
              qualified plan, the amount of Annual Additions which may be
              allocated under this Plan on a Member's behalf for a Plan Year
              shall not exceed the lesser of the Maximum Permissible Amount or
              any other limitation contained in this Plan.

                     (2)    Prior to the determination of the Member's actual
              Applicable Compensation for a Plan Year, the Maximum Permissible
              Amount may be determined on the basis of the Member's estimated
              annual Applicable Compensation for such Plan Year.  Such
              estimated annual Applicable Compensation shall be determined on a
              reasonable basis and shall be uniformly determined for all
              Members similarly situated.

                     (3)    As soon as is administratively feasible after the
              end of the Plan Year, the Maximum Permissible Amount for such
              Plan Year shall be determined on the basis of the Member's actual
              Applicable Compensation for such Plan Year.

                     (4)    If there are Excess Annual Additions with respect
              to a Member for the Limitation Year, such Excess Annual Additions
              shall be disposed of as follows:

                            A.     There shall first be returned to the Member
                     his unmatched Savings Contributions (and earnings
                     thereon), if any, and then a portion of his matched
                     Savings Contributions (and earnings thereon), to the
                     extent, and only to the extent, such returned Savings
                     Contributions would reduce the Excess Annual Additions.

                            B.     If any of such Excess Annual Additions shall
                     then remain, the Employer Contributions, including both
                     Salary Deferral Contributions defined in Section 4.2 and
                     matching Employer Contributions defined in Section 4.3,
                     allocated to the Member (and earnings thereon) shall then
                     be reduced to the extent necessary to eliminate such
                     remaining Excess Annual Additions.  The amount of the
                     reduction of the Employer Contributions for such Member
                     shall be reallocated first out of such Member's unmatched
                     Salary Deferral Contributions, then matching Employer
                     Contribution Account and then out of his Salary Deferral
                     Contribution Account, and shall be held in a suspense
                     account which shall be applied as a part of (and to reduce
                     to such extent what would otherwise be) the matching
                     Employer Contributions for all Members required to be made
                     to the Plan during the next subsequent calendar quarter or
                     quarters.  No portion of such Excess Annual Additions may
                     be distributed to Members or former Members.  If a
                     suspense account is in existence at any time during the
                     Plan Year pursuant to 




                                       IV-7
<PAGE>   27
                     this paragraph B, such suspense account shall not
                     participate in the allocation of investment gains or
                     losses of the Trust Fund.

       (b)    Two or More Defined Contribution Plans

                     (1)    If, in addition to this Plan, the Employer
              maintains any other qualified defined contribution plan, the
              amount of Annual Additions which may be allocated under this Plan
              on a Member's behalf for a Plan Year, shall not exceed the lesser
              of:

                            A.     the Maximum Permissible Amount, reduced by
                     the sum of any Annual Additions allocated to the Member's
                     accounts for the same Plan Year under such other defined
                     contribution plan or plans; or

                             B.     any other limitation contained in this Plan.

                     (2)    Prior to the determination of the Member's actual
              Applicable Compensation for the Plan Year, the amount referred to
              in Section 4.11(b)(1), may be determined on the basis of the
              Member's estimated annual Applicable Compensation for such Plan
              Year.  Such estimated annual Applicable Compensation shall be
              determined on a reasonable basis and shall be uniformly
              determined for all Members similarly situated.

                     (3)    As soon as is administratively feasible after the
              end of the Plan Year, the amounts referred to in Section
              4.11(b)(1) shall be determined on the basis of the Member's
              actual Applicable Compensation for such Plan Year.

                     (4)    If a Member's Annual Additions under this Plan and
              all such other defined contribution plans result in Excess Annual
              Additions, such Excess Annual Additions shall be deemed to
              consist of the amounts last allocated.

                     (5)    If Excess Annual Additions were allocated to a
              Member on an allocation date of another plan, the Excess Annual
              Additions attributed to this Plan will be the product of:

                            A.     the total Excess Annual Additions allocated
                     as of such date (including any amount which would have
                     been allocated but for the limitations of Code Section
                     415); times

                            B.     the ratio of (A) the amount allocated to the
                     Member as of such date under this Plan, divided by (B) the
                     total amount allocated as of such date under all qualified
                     defined contribution plans (determined without regard to
                     the limitations of Code Section 415).



                                       IV-8
<PAGE>   28
                     (6)    Any Excess Annual Additions attributed to this Plan
              shall be disposed of as provided in Section 4.11(a).

       (c)    Defined Contribution Plan and Defined Benefit Plan

                     (1)    General Rule - If the Employer maintains one or
              more defined contribution plans and one or more defined benefit
              plans, the sum of the "defined contribution plan fraction" and
              the "defined benefit plan fraction," as defined in Code Section
              415, cannot exceed 1.0 for any Plan Year.  For purposes of this
              paragraph (c) of Section 4.11, Employee contributions to a
              qualified defined benefit plan are treated as a separate defined
              contribution plan, and all defined contribution plans of an
              Employer are to be treated as one defined contribution plan and
              all defined benefit plans of an Employer are to be treated as one
              defined benefit plan whether or not such plans have been
              terminated.

                     (2)    If the sum of the defined contribution plan
              fraction and defined benefit plan fraction exceeds 1.0, the
              annual benefit of the defined benefit plan or plans (starting
              with this Plan first) will be reduced so that the sum of the
              fractions will not exceed 1.0.  In no event will the annual
              benefit be decreased below the amount of the accrued benefit to
              date.  If additional reductions are required for the sum of the
              fractions to equal 1.0, the reductions will then be made to the
              defined contribution plan or plans (starting with this Plan
              first).

       (d)    Incorporation by Reference

                     All provisions of Code Section 415 that may not be applied
              in more than one manner are hereby incorporated in the Plan by
              references and if any such incorporated provision conflicts with
              a provision in the Plan, such incorporated provision shall
              control.

4.12   ROLLOVER CONTRIBUTIONS:  An Employee who is in the Eligible Class shall
be eligible to make a rollover contribution (whether a "direct" or "indirect"
rollover) to the Plan by wire transfer or by check or other property acceptable
to the Committee, provided such contribution satisfies the requirements of
Section 402(a) of the Code as being a 'qualified rollover,' and the Employee
satisfies such other administrative requirements concerning such rollover
contributions as may be required, including designating the investment fund(s)
for such contribution.  Rollover contributions are not subject to an Employer
matching contribution.

4.13   VESTING:  Each person who was a Member or an Employee in the Eligible
Class on June 30, 1998 shall always be 100% vested in all of his Accounts,
except that any Member in the Tacoma Plan who was not an Employee on the date
it was merged into the Plan, shall continue to be vested in his merged Accounts
only to the extent vested therein on the merger date, unless he again becomes
an Employee.  Each person who becomes a Member after June 30, 1998 shall always
be



                                       IV-9
<PAGE>   29
100% vested in his Savings Contributions, Salary Deferral and Rollover
Accounts, and shall become 100% vested in his Employer Contribution Account
based on his Years of Service in accordance with the following schedule:


<TABLE>
<CAPTION>
       Years of Service     Vested Percentage
       ----------------     -----------------
         <S>                        <C>
         less than 3                 0%
         3 or more                 100%

</TABLE>

       Regardless of his Years of Service however, a Participant who is an
Employee on or after reaching age 65 shall be 100% vested in all his Accounts.
Further, in the event a Participant's employment with the Employers and
Affiliated Companies is terminated by reason of disability (as determined for
purposes of Title II of the Federal Social Security Act) or death, he shall
also be deemed to be 100% vested in all his Accounts.

       Notwithstanding the foregoing schedule, in the event the Plan is
terminated or partially terminated or the Employers' contributions under the
Plan are completely discontinued, each affected Member shall thereupon be 100%
vested in all his Accounts as of the date of such discontinuance or termination
or partial termination.

                                  INVESTMENTS

5.1    DIRECTION OF INVESTMENTS:

              (a)    Each Member shall direct, when he authorizes Savings
       Contributions, elects to have made Salary Deferral Contributions or
       makes a Rollover Contribution, that such contributions be invested in
       one or more of the investment funds offered under the Plan (as set forth
       on Attachment A, which is made a part of the Plan for all purposes) in
       increments of 1%; provided, however, a Rollover Contribution may not be
       invested in the Company Stock Fund.  Employer matching contributions
       shall be invested in the same manner as the Member's contributions with
       respect to which they are made.  The Committee may, from time to time,
       add additional investment funds and/or delete existing investment funds
       offered under the Plan by giving advance notice to the Members.  The
       Committee shall have the full power and authority to make such rules as
       necessary or appropriate to add or delete a fund, including amending the
       Plan and Trust to effectuate such change.

              (b)    Each Member may change the investment of the existing
       balances in his Accounts, by authorizing a transfer from one investment
       fund to one or more of the other investment funds in 1% increments, as
       of any Valuation Date by giving notice to the Plan's record keeper in
       accordance with the Plan's administrative procedures then in effect;
       provided, however, existing Account balances may not be transferred into
       the Company Stock Fund.

              (c)    Each Member may change the current investment direction
       concerning his future Savings and Salary Deferral Contributions as of
       any Valuation Date by giving notice to the Plan's record keeper in
       accordance with the Plan's administrative procedures then in effect.

5.2    COMPANY STOCK FUND:  With respect to the Company Stock Fund, the Trustee
shall vote the shares of Company Stock held in the Company Stock Fund for the
respective Accounts of the Members in accordance with the directions of such
Members, provided such directions are received by the Trustee at least five
days before the date set for the meeting at which such shares are to be voted.
The Trustee shall not vote shares of Company Stock for which it has not
received timely instructions on a particular matter, unless otherwise required
by ERISA.  Each Member (or, in the event of his death, his beneficiary) shall
have the right, to the extent of the number of shares of Company Stock
allocated to his Accounts in the Company Stock Fund, respectively, to instruct
the Trustee in writing as to the manner in which to respond to a tender offer
or exchange offer with respect to such shares.  The Committee shall use its
best efforts timely to distribute or cause to be distributed to each Member (or
beneficiary thereof) such information as will be distributed to stockholders of
the Company in connection with any such tender offer or exchange offer.  Upon
timely receipt of such instructions, the Trustee shall respond as instructed
with respect to shares of such stock.  The instructions received by the Trustee
from Members shall be held by the Trustee in



                                       V-1
<PAGE>   31
confidence and shall not be divulged or released to any person, including
officers or employees of the Corporation or any Affiliated Company.  If the
Trustee shall not receive timely instructions from a Member (or beneficiary
thereof) as to the manner in which to respond to such tender offer or exchange
offer, such Member (or beneficiary) shall be deemed to have instructed the
Trustee not to tender or exchange the Company Stock.

                   PAYMENT OF CONTRIBUTIONS  AND  ALLOCATIONS

6.1    PAYMENT OF CONTRIBUTIONS:  Each Employer shall, as soon as reasonably
practicable following each payroll period, pay to the Trustee the amounts
representing payroll deductions pursuant to Savings Contributions and the
amounts representing salary reductions pursuant to its Members Salary Deferral
Contributions.  Employer Contributions shall be made to the Trustee in full
prior to the due date including extensions thereof, for filing the Employer's
federal income tax return for its taxable year which ends coincident with the
end of such Plan Year or within which such Plan Year ends, as the case may be.
The Trustee shall hold or apply the contributions so received by it in
accordance with the provisions of the Plan; and no part thereof shall be used
for any purpose other than the exclusive benefit of the Members or their
beneficiaries. Contributions shall be made in cash (by check or wire transfer)
or, with respect to Employer Contributions to be invested in the Company Stock
Fund, in the sole discretion of the Corporation, in shares of Company Stock.

6.2    VALUATION OF TRUST FUND: The Trustee shall value the assets of the Trust
Fund at fair market value as of each Valuation Date.  With respect to an
Account (or the portion thereof) that is invested in a mutual fund, the fair
market value shall be determined based on the reported value of a unit in such
fund for the applicable Valuation Date.  With respect to an Account (or the
portion thereof) that is invested in the Company Stock Fund, the fair market
value shall be the fair market value of the shares of Company Stock allocated
to such Account on the applicable Valuation Date.  The Trustee's determination
of the value of any Account shall be final and conclusive for all purposes of
the Plan.

6.3    FUNDING POLICY: The provisions of Articles IV and VI shall be deemed the
procedure for establishing and carrying out the funding policy and method of
the Plan.  Such funding policy and method shall be administered by the
Employers and other fiduciaries consistent with the objectives of the Plan and
with the requirements of Title I of ERISA.

                           DISTRIBUTION  OF  ACCOUNTS

7.1    TIME OF DISTRIBUTION:  For separations from service occurring after
1997, if the vested value of the Member's Accounts is less than or equal to
$5,000 (for separations from service prior to 1998, $3,500 shall be substituted
for $5,000 here and below, unless IRS rules permit the $5,000 limit to apply to
such Members), distribution of the Member's Accounts shall be made as soon as
practicable after the Member's separation from service; however, if the total
vested value of the Member's Accounts exceeds (or at the time of any prior
withdrawal or distribution, exceeded) $5,000, the Member's Accounts shall be
distributed only upon his written consent following his separation of service,
but in any event no later than 60 days after the end of the Plan Year in which
occurs the earlier of the Member's death or attainment of age 65.  If a
Member's termination of service occurs after attainment of age 65, distribution
shall be made within 60 days after the end of the Plan Year in which
termination occurs; however, Effective January 1, 1997, benefit payments to any
Member who reaches age 70-1/2 prior to 1999 (excluding any 5% or more owner)
must begin by April 1 of the calendar year following the year in which the
individual attains age 70-1/2, whether or not the person has terminated
service, unless such Member (excluding any 5% or more owner) elects to defer
distribution until his termination of employment.  All benefits payable because
of a Member's death shall be paid to the Member's beneficiary in a single,
lump-sum distribution as soon as practicable and in all events within five
years of the Member's date of death.  If a Member dies after distributions have
begun following his termination of employment and before his entire interest
has been distributed to him, the remaining portion will be distributed to his
beneficiary at least as rapidly as the method in effect on the Member's date of
death.

       Notwithstanding anything in the Plan to the contrary, amounts held in
the Member's Salary Deferral Contribution Account may not be distributable
prior to the earlier of:

              (a)    his separation from service (within the meaning of Code
       Section 401(k)), total and permanent disability, or death;

months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

hardship withdrawal from his Salary Deferral Contribution Account and, if fully
vested, his Employer Contribution Account.  The approval or disapproval of such
request shall be made by the Committee.  The Committee shall not approve any
such request unless it finds that the Member is facing a hardship creating an
"immediate and heavy financial need" (as defined below) and the Member has
obtained all distributions, other than hardship distributions, and all
nontaxable loans currently available under the Plan and all other plans of the
Employer and its ERISA affiliates.  To the extent the Member is fully vested in
his Employer Contribution Account, the withdrawal shall be taken first from
that Account.  The amount of the hardship withdrawal shall be limited to an
amount that does not exceed:  (1) that amount which the Committee determines to
be required to meet the immediate financial needs created by the hardship,
which may include any amounts necessary to pay any federal, state or local
income taxes or penalties reasonably anticipated to result from the
distribution, and (2) if made from the Participant's Salary Deferral
Contribution Account, the amount of the Salary Deferral Contribution Account,

hardship distribution is made under the Plan, the restrictions set forth in

       heavy financial need" if it is on account of:



                                       VII-3
<PAGE>   36
                     (1)    Medical expenses described in section 213(d) of the
              Code incurred by the Member, the Member's spouse, or any
              dependents of the Member (as defined in section 152 of the Code)
              or necessary for these persons to obtain such medical care;

                     (2)    Costs directly related to the purchase (excluding
              mortgage payments) of a principal residence for the Member;

                     (3)    Payment of tuition, related educational fees, and
              room and board expenses for the next 12 months of post-secondary
              education for the Member, his or her spouse, children, or
              dependents; or

                     (4)    The need to prevent the eviction of the Member from
              his principal residence or foreclosure on the mortgage of the
              Member's principal residence; or

                     (5)    any other "safe-harbor" event established from time
              to time by the Internal Revenue Service.

              (b)    Upon a hardship distribution,

                     (1)    The Member's 401(k) contributions and after-tax
              contributions under the Plan, and all other plans maintained by
              the Employer and its ERISA affiliates (other than a health or
              welfare benefit plan or the mandatory employee contribution
              portion of a defined benefit plan), will be suspended for 12
              months, and

                     (2)    The Member may not make 401(k) contributions under
              the Plan, and all other plans maintained by the Employer and its
              ERISA affiliates, for the Member's taxable year immediately
              following the taxable year of the hardship distribution in excess
              of the applicable limit under Code Section 402(g) for such next
              taxable year less the amount of the Member's elective
              contributions for the taxable year of the hardship distribution.

       Withdrawals shall be in cash unless the Account is invested in the
Company Stock Fund and the Member elects to withdraw shares.

       If the withdrawal made pursuant to this Section 7.3 is with respect to a
contribution that received a matching Employer contribution in the preceding 24
months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.7    LOANS TO MEMBERS:  Loans shall be granted in a uniform and non-
discriminatory manner to Members (as used herein, a Member includes a
beneficiary) from their Accounts, provided the Member is a "party in interest"
under ERISA, subject to the following terms and conditions:



                                       VII-4
<PAGE>   37
              (a)    Loans made pursuant to this Section (when added to the
       outstanding balance of all other loans made by the Plan to the Member)
       shall be limited to the lesser of:

                     (1)    $50,000 reduced by the excess (if any) of the
              highest outstanding balance of loans from the Plan to the Member
              during the one-year period ending on the day before the date on
              which such loan is made, over the outstanding balance of loans
              from the Plan to the Member on the date on which such loan was
              made, or

                     (2)    one-half of the value of the vested portion of the
              Member's Accounts.

       For purposes of this limit, all plans of the Employer and Affiliated
       Companies shall be considered one plan.  Each loan must be for at least
       $1,000.

              (b)    Loans shall provide for the level amortization of
       principal and interest with payments to be made not less frequently than
       monthly over a period not to exceed five years.  However, loans used to
       acquire any dwelling unit which, within a reasonable time, is to be used
       (determined at the time the loan is made) as a principal residence of
       the borrower shall provide for periodic repayment over a period of time
       not to exceed ten years.  Loans shall be evidenced by a note signed by
       the Member payable in monthly installments.  All loans shall bear
       interest at the rate in effect in the commercial loan division of the
       Trustee or an affiliated bank to the Trustee for loans of a similar
       nature on the date the loan is made, and if the Trustee does not provide
       such a rate of interest itself or through an affiliated bank, then the
       rate at any bank handling the Company's accounts as determined by the
       Committee, for loans of a similar nature on the date the loan is made.

              (c)    Loans must be repaid by means of an irrevocable payroll
       deduction election, unless the Member is not receiving a salary from the
       Employer that is sufficient to allow deduction of the full loan
       payments, in which case any excess of payments due over the amount
       deductible from the Member's salary shall be paid to the Plan by the
       Member in level installments each pay period, but in no event less
       frequently than monthly.  All loans shall become due and payable in full
       upon the date a Member ceases to be a "party in interest" to the Plan.

              (d)    Loans shall be made first from the Rollover Account, then
       the Salary Deferral Contribution Account.  If the balance in the Salary
       Deferral Contribution Account is less than the amount of the requested
       loan, the remainder of the loan shall be made next from the Employer
       Contribution Account, and last from the Savings Contribution Account.
       Any loan under the Plan shall be secured by the pledge of all of the
       Member's right, title and interest in an amount of his or her vested
       Accounts equal to the amount of the loan, but not exceeding 50% of such
       vested Accounts as determined immediately after such loan. Such pledge
       shall be executed by the Member and his Spouse, if any, which shall
       provide that, in the event of any default on a loan repayment, the
       Committee shall be authorized to take any and all appropriate lawful
       actions necessary to enforce collection of



                                       VII-5
<PAGE>   38
       the unpaid loan.  In addition, the promissory note shall provide that,
       in the event of a default on the loan repayment, both the principal and
       accrued, unpaid interest shall be immediately due and payable.  If the
       Member is subject to the provisions of Section 401(a)(11) of the Code at
       the time the vested Accounts are pledged as  security for the loan, the
       spousal consent must be obtained in the proper form.

              (e)    A request for a loan shall be made in accordance with the
       Plan's administrative procedures, which may specify the order in which
       the investment fund(s) within each of the Account(s) are invested shall
       be redeemed to make the requested loan, and shall constitute a written
       consent to a distribution or deemed distribution of the Account(s), if
       necessary, in the event of a default.  If a request for a loan is
       approved by the Committee, the Committee shall furnish or cause to be
       furnished the Trustee with instructions directing the Trustee to make
       the loan in a lump-sum payment of cash to the Member.

              (f)    A loan shall be considered an investment of the separate
       Account(s) of the Member from which the loan is made.  All loan
       repayments of principal and interest shall be credited to such separate
       Account(s) and reinvested in the investment funds in accordance with the
       Member's election in effect for his current contributions, or, if none
       is in effect, his most recent such election.

              (g)    Only two loans may be outstanding at any time to a Member.

              (h)    Loan repayments will be suspended under this Plan as
       permitted under Code Section 414(u)(4).

              (i)    All or part of the reasonable administrative costs of
       establishing and maintaining a loan may be charged to the borrowing
       Member.

7.8    METHODS OF DISTRIBUTION:  Distributions shall be made in a lump sum in
cash (and, with respect to Accounts invested in the Company Stock Fund, in
shares of Company Stock, if elected) unless a Member (and his Spouse, if
applicable) have made the proper election to receive one of the following
optional forms of payment.

              (a)    Joint and Survivor Annuity.  If a Member is married on the
       benefit payment date and elects not to receive a lump sum, distribution
       shall be in the form of a Joint and Survivor Annuity, which shall be an
       annuity for the life of the Member with a contingent annuity for the
       life of the Member's Spouse, if she survives him, which is 50% of the
       amount of the annuity payable to the Member had he lived.  The Joint and
       Survivor Annuity shall be maximum amount that may be obtained by
       purchasing an annuity contract with the Member's Accounts from an
       insurance company selected by the Committee.  Subject to Sections 7.9
       and 9.1, a married Member may elect to receive the Single Life Annuity
       or to designate someone other than his Spouse as his contingent joint
       annuitant; provided it must



                                       VII-6
<PAGE>   39
       be expected that the Member will receive more than 50% of the present
       value of his Accounts under such annuity.

              (b)    Single Life Annuity.  If a Member who is not married on
       the benefit payment date elects not to receive a lump sum, the Member
       shall receive his distribution in the form of a Single Life Annuity
       providing him with equal monthly payments for his lifetime.  The amount
       of such annuity shall be the maximum amount that may be obtained by
       purchasing an annuity contract with the Member's Accounts from an
       insurance company selected by the Committee.  Subject to Section 7.9,
       the Member may elect to receive the Joint and Survivor Annuity.

              (c)    A Member may elect to receive his distribution in annual,
       semi-annually, quarterly or monthly installments payable in
       substantially equal amounts continuing over a period certain not
       exceeding the Member's (or the Member's and his beneficiary's joint)
       life expectancy(ies) as of the date such payments begin.  At the time of
       the election, the Member must specify the fixed period and the frequency
       of the installments elected.  The installment payments shall be provided
       from an insurance company contract purchased with the amount of the
       Accounts.

7.9    ELECTION TO RECEIVE AN ANNUITY:  The Committee shall furnish certain
general information pertinent to the annuities to each Member at least 30 but
not more than 90 days prior to such Member's benefit payment date.  The
furnished information shall be in accordance with such regulations as the
Secretary of the Treasury may prescribe and shall include a general explanation
of (i) the annuity, (ii) the Member's right to make, and the effect of an
election or revocation of an election to receive the annuity, and (iii) the
rights of the Spouse with respect to the Joint and Survivor Annuity.  The
period of time during which a Member may make the election described in this
Section 7.9 shall be at any time during the 90-day period prior to the Member's
benefit payment date.  Any election may be revoked and subsequent elections may
be made or revoked at any time and any number of times during such election
period.

7.10   PRE-RETIREMENT SURVIVOR ANNUITY:  Except as provided below, if a married
Member who has elected the Joint and Survivor Annuity dies before his benefit
payment date, his Spouse shall receive a Pre-retirement Survivor Annuity
commencing as soon as practicable following the date of the Member's death;
however, the Spouse may direct that the annuity start on any subsequent date
specified by the Spouse which is not later than the date the Member would have
reached age 65.  The amount of the annuity (equal monthly payments for the
Spouse's lifetime) shall be the maximum amount that may be obtained with the
Member's Accounts by purchasing an annuity contract from an insurance company
selected by the Committee.

       A Spouse who is entitled to receive the Pre-retirement Survivor Annuity
may elect to receive a lump sum payment of the Member's Accounts in lieu of the
annuity by furnishing the Committee the proper form at any time prior to the
date such insurance contract is purchased.



                                       VII-7
<PAGE>   40
7.11   ELECTION NOT TO RECEIVE THE PRE-RETIREMENT SURVIVOR ANNUITY:  A Member
who has elected to receive the Joint and Survivor Annuity may elect, by
executing the election form prescribed by the Committee, not to be covered by
the Pre-retirement Survivor Annuity.  Such election must be made during the
election period described below.  Any election may be revoked and subsequent
elections may be made or revoked at any time during such election period.  Any
such election and any revocation of such election must be signed by the
Member's Spouse and acknowledge the effect of such election on the Spouse's
right to benefits and further, the Spouse's signature must be notarized, and
designate a specific beneficiary and the specific form of payment that cannot
be changed without a new spousal consent.

       The Committee shall furnish certain general information pertinent to
this election to each Member within the period beginning on the first day of
the Plan Year in which the Member attains age 32 and ending with the close of
the Plan Year preceding the Plan Year in which the Member attains age 35.  With
respect to an Employee who becomes a Member of the Plan after the date the
general information is required to be furnished, such information shall be
furnished on or about the date that such Member begins participation in the
Plan.  The furnished information shall be written in accordance with such
regulations as the Secretary of Treasury may prescribe and shall contain a
general explanation of (i) the terms and conditions of Pre-retirement Survivor
Annuity (ii) the Member's right to make and the effect of, an election or
revocation of an election to waive the Pre-retirement Survivor Annuity, and
(iii) the rights of the Member's Spouse with respect to the Pre-retirement
Survivor Annuity.  The Member may make or revoke the election described in this
Section 7.11 at any time.

7.12   DIRECT ROLLOVER:  Notwithstanding any provision of the Plan to the
contrary that would otherwise limit a distributee's election under this
Section, a distributee may elect, at the time and in the manner prescribed by
the Committee, to have any portion of an eligible rollover distribution paid
directly to an eligible retirement plan specified by the distributee in a
direct rollover.

       Eligible rollover distribution:  An eligible rollover distribution is
any distribution of all or any portion of the balance to the credit of the
distributee, except that an eligible rollover distribution does not include:
any distribution that is one of a series of substantially equal periodic
payments (not less frequently than annually) made for the life (or life
expectancy) of the distributee or the joint lives (or joint life expectancies)
of the distributee and the distributee's designated beneficiary, or for a
specified period of ten years or more; any distribution to the extent such
distribution is required under section 401(a)(9) of the Code; and the portion
of any distribution that is not includible in gross income (determined without
regard to the exclusion for net unrealized appreciation with respect to
employer securities).

       Eligible retirement plan:  An eligible retirement plan is an individual
retirement account described in section 408(a) of the Code, an individual
retirement annuity described in section 408(b) of the Code, an annuity plan
described in section 403(a) of the Code, or a qualified trust described in
section 401(a) of the Code, that accepts the distributee's eligible rollover
distribution.  However,



                                       VII-8
<PAGE>   41
in the case of an eligible rollover distribution to the surviving spouse, an
eligible retirement plan is an individual retirement account or individual
retirement annuity.

       Distributee:  A distributee includes an Employee or former Employee.  In
addition, the employee's or former Employee's surviving spouse and the
Employee's or former Employee's spouse or former spouse who is the alternate
payee under a qualified domestic relations order, as defined in section 414(p)
of the Code, are distributees with regard to the interest of the spouse or
former spouse.

       Direct rollover:  A direct rollover is a payment by the plan to the
eligible retirement plan specified by the distributee.

7.13   30-DAY WAIVER:  If a distribution is one to which sections 401(a)(11)
and 417 of the 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 Committee clearly informs the Member that the Member
       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 Member, after receiving the notice, affirmatively
       elects a distribution.

7.14   FORFEITURES: Upon a Member's termination of employment with the
Employers and Affiliated Companies the nonvested portion of the Member's
Employer Contributions Account (if any) shall continue to be held in the Trust
until forfeited as of the earlier of the date the Member incurs five
consecutive Breaks in Service or receives a complete distribution of his vested
Accounts.  Forfeited account balances shall be used to reduce future Employer
contributions otherwise due under the Plan.  However, if a Member again becomes
an Employee in the Eligible Class prior to incurring five consecutive Breaks in
Service, his forfeited amount shall be restored, unadjusted for any interim
Trust fund gains or losses, through a special allocation of then existing
forfeitures and/or additional Employer contributions, provided the Member
repays the full amount of such prior distribution to the Plan in cash before
the fifth anniversary of his reemployment date or prior to incurring five
consecutive Breaks of Service, whichever occurs first.

shall not be interrupted by, the following authorized absences for which the
Employee is not directly or indirectly paid:

              (a)    Absence due to accident or sickness so long as the Member

       Company and remains eligible to work upon his recovery.

              (b)    Absence due to an authorized absence for a period not to
       exceed two years for such reasons and subject to such conditions as may
       be approved by the board of directors of his Employer for general
       application to all Employees similarly situated, provided that each such
       Member shall immediately, upon expiration of such authorized absence,
       apply for reinstatement in the employment of the employing company.

              (c)    Absences in compliance with the Family Medical Leave Act.

              Notwithstanding any provision of this Plan to the contrary,
contributions, benefits and service credit with respect to qualified military
service will be provided in accordance with Code Section 414(u).

8.2    EFFECT OF AUTHORIZED ABSENCES:  Members on Authorized Absence status
shall be treated as if they were employed by a non-participating Affiliated
Company.

                      BENEFICIARIES IN THE EVENT OF DEATH

9.1    BENEFICIARIES:  Upon the death of a Member, his Vested Accounts shall be
distributed to the beneficiary or beneficiaries designated by him in a written
designation on a Plan form filed with his Employer or, if no such designation
shall have been so filed, to his Spouse or, if none, to his estate.  No such
designation of beneficiary shall be effective (whether or not made prior to
marriage) if the Member has a Spouse as of his date of death, unless such
Spouse is designated as the sole beneficiary, or unless such Spouse consents to
the designation of another specified person (and form of payment) as
beneficiary.  The Spouse's consent must be in writing, acknowledge the effect
of the consent on the Spouse's right to benefits under the Plan, and be
witnessed by a Plan representative or a notary public.  The beneficiary
designated by the Member may not be changed without the Spouse's consent,
however, a revocation of a designation of a beneficiary other than the Spouse
may be made by a Member without the consent of the Spouse at any time before
the distribution of the benefit under the Plan.  The Spouse's consent to a
beneficiary designation shall not be required if it is established to the
satisfaction of the Committee that such written consent may not be obtained
because there is no Spouse or the Spouse cannot be located.  Any consent under
this Article IX will be valid only with respect to the Spouse who signs the
consent.  The divorce of a Member shall automatically revoke such former spouse
as his beneficiary under the Plan, except to the extent otherwise provided in a
qualified domestic relations order.

10.1   ADMINISTRATIVE COMMITTEE:  The Corporation shall act as the
administrator of the Plan and shall have all of the powers and responsibilities
conferred upon administrators under ERISA.  However, an Administrative
Committee composed of such persons, as may be determined from time to time by
the Board of Directors, may be appointed by the Board to perform the duties of
the Corporation.

       The Committee shall elect a Chairman from its number, and a Secretary,

at any later date specified therein.

       No member of the Committee who is also an officer or employee of any of
the Companies receiving compensation as such shall receive any compensation for
his services as such member.  No bonds or other security shall be required of

relating solely to his own Account or any other right or privilege under the
Plan.

10.2   POWER OF THE COMMITTEE:  The Committee shall have the power:

              (d)    To authorize one or more of their number, or any agent, to
       make any payment, or to execute or deliver any instrument, on behalf of
       the Committee, except that all



                                       X-1
<PAGE>   45
       requisitions for funds from, and requests, directions, notifications,
       certifications, and instructions to, the Trustee or to the Company or
       Affiliated Companies shall be signed on behalf of the Committee by two
       members of the Committee, provided that one of the members signing shall

              (e)    To fix and determine the proportions of costs of the Plan

              (h)    To prescribe forms and procedures to be followed by
       Employees applying for membership, Members electing or changing Savings
       Contributions or Salary Deferral Contributions, Members or beneficiaries
       filing applications for benefits, Members applying for withdrawals, and
       other occurrences in the administration of the Plan;

              (i)    To prepare and distribute, in such manner as the Committee
       determines to be appropriate, information explaining the Plan;

              (j)    To receive from the Company, or Affiliated Companies, and
       from Members, such information as shall be necessary for the proper
       administration of the Plan;

              (k)    To furnish the Company or Affiliated Companies, upon

       Plan as are reasonable and appropriate;

              (l)    To receive, review and keep on file (as it deems

subject, however, to the provisions of the Plan and the Trust Agreement.



                                       X-2
<PAGE>   46
       Subject to the limitations of the Plan, the Committee, from time to
time, shall establish rules for the administration of the Plan and the
transaction of its business.  As to all matters of administration not reserved
in the Plan to the Board of Directors or the Boards of Directors of the
Employers, the determination of the Committee as to any disputed question shall
be conclusive.  All such rules and decisions of the Committee shall be
uniformly and consistently applied in order that all Members in similar
circumstances shall be treated alike.

       It shall be the duty of the Committee to notify the Trustee in writing
of the termination of service of any Member under the Plan and of the amount of
cash which shall be payable to such Member upon termination of service, and the
date distributions are to commence.  The Committee shall not requisition any
payment from the Trustee except upon certification by the Committee that such
amount is for payment of benefits under the Plan or for the payment of expenses
of administering the Plan.  Any such certification by the Committee shall be
deemed conclusively true insofar as the Trustee is concerned.

       All resolutions or other actions taken by the Committee at the meeting
shall be by vote of the majority of the Committee attending the meeting.

10.4   ACCOUNTS RECORDS:  The Committee shall maintain accounts showing the
fiscal transactions of the Plan and shall keep, or cause the Employers to keep,
in convenient form, such data as may be necessary for valuation of the assets.
The Committee shall prepare annually a report showing in reasonable summary the
assets and liabilities of the Plan and giving a brief account of the operation
of the Plan for the past Plan Year and any further information which the Boards
of Directors of the Employers may require and as the Committee can reasonably
furnish or can obtain from the Trustee.  Such report shall be submitted to the
Boards of Directors of the Employers and shall be filed in the office of the
Secretary of the Committee, where it shall be open to inspection by any Member.
The Committee shall exercise such other authority and responsibility as it
deems appropriate in order to comply with ERISA and governmental regulations
issued thereunder relating to (i) records of Members' service, Account balances
and the percentage of such Account balances which are nonforfeitable under the
Plan; (ii) notifications to Members; and (iii) annual reports to the Internal
Revenue Service.  Unless otherwise required by law, the Committee may authorize
any method of accounting for, or of reporting, information with respect to Plan
assets and Account balances which fairly and accurately presents the fair
market value, determined in accordance with the Plan, of the Plan assets and
Account balances as of such date.

10.5   ALLOCATION OF RESPONSIBILITY AMONG FIDUCIARIES FOR PLAN AND TRUST FUND
ADMINISTRATION:  The fiduciaries of the Plan shall have only those specific
powers, duties, responsibilities and obligations as are specifically given them
under this Plan or the Trust Agreement.  In general, the Companies shall have
the sole responsibility for making the contributions provided under Article IV.
The Board of Directors shall have the sole authority to appoint and remove the
Trustee, members of the Committee and to amend or terminate, in whole or in
part, this Plan or the Trust.  The Committee shall have the sole responsibility
for the administration of this Plan, which responsibility is specifically
described in this Plan and the Trust.  The Committee shall have the sole
responsibility



                                       X-3
<PAGE>   47
for selecting an entity to hold and manage the assets in the Plan and for
selecting a guaranteed investment contract(s) to be acquired by the Trustee.
The Trustee shall have the sole responsibility for the administration of the
Trust Fund and the management of the assets held under the Trust, except when
an Investment Manager has been appointed by the Committee, all as specifically
provided in the Trust.  Each fiduciary shall warrant that any directions given,
information furnished, or action taken by it shall be in accordance with the
provisions of the Plan or the Trust Agreement, as the case may be, authorizing
or providing for such direction, information or action.  Furthermore, each
fiduciary may rely upon any such direction, information or action of another
fiduciary as being proper under this Plan or the Trust, and is not required
under this Plan or the Trust Agreement to inquire into the propriety of any
such direction, information or action.  It is intended under this Plan and the
Trust Agreement that each fiduciary shall be responsible for the proper
exercise of its own powers, duties, responsibilities and obligations under this
Plan and the Trust and shall not be responsible for any act or failure to act
of another fiduciary.  No fiduciary guarantees the Trust Fund in any manner
against investment loss or depreciation in asset value.

10.6   PRESENTING CLAIMS FOR BENEFIT:   Any Member or any beneficiary claiming
under a deceased Member, may submit written application to the Committee for
the payment of any benefit asserted to be due him under the Plan.  Such
application shall set forth the nature of the claim and such other information
as the Committee may reasonably request.  Promptly upon the receipt of any
application required by this Section 10.6, the Committee shall determine
whether or not the Member or beneficiary involved is entitled to a benefit
hereunder and, if so, the amount thereof and shall notify the claimant of its
findings.

       If a claim is wholly or partially denied, the Committee shall so notify
the claimant within 90 days after receipt of the claim by the Committee, unless
special circumstances require an extension of time for processing the claim.
If such an extension of time for processing is required, written notice of the
extension shall be furnished to the claimant prior to the end of the initial
90-day period.  In no event shall such extension exceed a period of 90 days
from the end of such initial period.  The extension notice shall indicate the
special circumstances requiring an extension of time and the date by which the
Committee expects to render its final decision.  Notice of the Committee's
decision to deny a claim in whole or in part shall be set forth in a manner
calculated to be understood by the claimant and shall contain the following:

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

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

              (c)    a description of any additional material or information
       necessary for the claimant to perfect the claim and an explanation of
       why such material or information is necessary, and

              (d)    an explanation of the claims review procedure set forth in
       Section 10.7 hereof.



                                       X-4
<PAGE>   48
       If notice of denial is not furnished, and if the claim is not granted 
within the period of time set forth above, the claim shall be deemed
denied for purposes of proceeding to the review stage described in Section
10.7.

10.7   CLAIM REVIEW PROCEDURE:  If an application filed by a Member or
beneficiary under Section 10.6 above shall result in a denial by the Committee
of the benefit applied for, either in whole or in part, such applicant shall
have the right, to be exercised by written application filed with the Committee
within 60 days after receipt of notice, of the denial of his application or, if
no such notice has been given, within 60 days after the application is deemed
denied under Section 10.6 to request the review of his application and of his
entitlement to the benefit applied for.  Such request for review may contain
such additional information and comments as the applicant may wish to present.
Within 60 days after receipt of any such request for review, the Committee
shall reconsider the application for the benefit in light of such additional
information and comments as the applicant may have presented, and if the
applicant shall have so requested, shall afford the applicant or his designated
representative a hearing before the Committee.  The Committee shall also permit
the applicant or his designated representative to review pertinent documents in
its possession, including copies of the plan document and information provided
by the Company relating to the applicant's entitlement to such benefit.  The
Committee shall make a final determination with respect to the applicant's
application for review as soon as practicable, and in any event not later than
60 days after receipt of the aforesaid request for review, except that under
special circumstances, such as the necessity for holding a hearing, such 60-day
period may be extended to the extent necessary, but in no event beyond the
expiration of 120 days after receipt by the Committee of such request for
review.  If such an extension of time for review is required because of special
circumstances, written notice of the extension shall be furnished to the
applicant prior to the commencement of the extension.  Notice of such final
determination of the Committee shall be furnished to the applicant, in writing,
in a manner calculated to be understood by him, and shall set forth the
specific reasons for the decision and specific references to the pertinent
provisions of the Plan upon which the decision is based.  If the decision on
review is not furnished within the time period set forth above, the claim shall
be deemed denied on review.

10.8   DISPUTED BENEFIT:  If any dispute shall arise between a Member or other
person claiming under a Member and the Committee after the review of a claim
for benefits, or in the event any dispute shall develop as to the person to
whom the payment of any benefit under the Plan shall be made, the Trustee may
withhold the payment of all or any part of the benefits payable hereunder to
the Member or other person claiming under the Member until such dispute has
been resolved by a court of competent jurisdiction or settled by the parties
involved.

10.9   UNCLAIMED BENEFIT:  If at, after, or during the time when a benefit
hereunder is payable to any Member, beneficiary or other distributee, the
Committee, upon request of the Trustee, or at its own instance, shall mail by
registered or certified mail to such Member, beneficiary or distributee, at his
last known address a written demand for his then address or for satisfactory
evidence of his continued life, or both, and if such Member, beneficiary or
distributee shall fail to furnish the same to the Committee within two years
from the mailing of such demand, then the Committee may, in



                                       X-5
<PAGE>   49
its sole discretion, determine that such Member, beneficiary or other
distributee has forfeited his right to such benefit and may declare such
benefit, or any unpaid portion thereof, terminated as if the death of the
distributee (with no surviving beneficiary) had occurred on the date of the
last payment made thereon, or on the date such Member, beneficiary or
distributee first became entitled to receive benefit payments, whichever is
later; provided, however, that such forfeited benefit shall be reinstated if a
claim for the same is made by the Member, beneficiary or other distributee at
any time thereafter.  Reinstatement shall be made by Company contributions or
forfeitures, if any.

11.1   ESTABLISHMENT: A Trust Fund shall be established, operated and
maintained exclusively for the collective investment and reinvestment of moneys
received from Members and Employers, in accordance with the investment
directions of Members, and the Trust Fund shall be under the exclusive
management and control of the Trustee, except when and for the specific
purposes that an Investment Manager has been properly appointed and is acting
pursuant to direction of the Committee.

11.2   EXCLUSIVE INVESTMENTS:  The Trustee shall invest moneys in the Trust
Fund exclusively in the investments funds provided for under the Plan.

11.3   BENEFICIAL INTERESTS:  Each Member shall have a beneficial interest in
the Trust Fund.  No Member shall have priority or preference over any other
Member as to any assets of the Plan.

11.4   SEPARATE ACCOUNTS:  The Committee shall maintain separate accounts for
each Member to reflect each Member's interest in the Trust Fund.  Each Member
shall have an Employer Contribution Account, a Savings Contribution Account, a

Stock, subject to any investment limits in Section VII.

                                  ARTICLE XII
              TERMINATION, AMENDMENT AND MODIFICATION OF THE PLAN

12.1   POWERS RESERVED:  The Corporation, by action of its Board of Directors,
may terminate the Plan in its entirety, or as to any Employer at any time, or
may at any time, or from time to time, amend or modify it, except that no
amendment or modification shall reduce (directly or indirectly) an accrued
benefit, eliminate an optional form of benefit (except as otherwise permitted
by regulations) or adversely change the vesting schedule with respect to any
Employee who is credited with three or more years of service.  In addition the
Committee may amend the Plan, subject to the foregoing limitations, provided
that any amendment by the Committee may not materially increase the
Corporation's obligations under the Plan.  Any such termination, amendment or
modification shall be effective at such date as the Corporation may determine.
An amendment or modification to the Plan may be effective as to all Companies
or as to any one of them, and their respective employees.  An amendment or
modification which increases the duties of the Trustee may be made only with
the consent of the Trustee.  An amendment or modification may affect Members in
the Plan at the time thereof, as well as future Members, but may not diminish
the account of any Member as of the effective date of amendment or modification
unless required by the Internal Revenue Service in order for the plan to
continue to be a qualified plan under Code Section 401.

12.2   EFFECT OF TERMINATION:  Upon any total or partial termination of the
Plan or upon discontinuance of contributions by any Employer, each affected
Member, as to whom the Plan is terminated, or as to whom Employer Contributions
have been discontinued, shall receive a fully vested interest in his Accounts.
Upon a termination of the Plan, distribution shall be made only in accordance
with the modes of distributions provided for under the Plan and subject to
their requirements; provided, however, written consent with respect to accounts
greater than $5,000 shall not be required if the Corporation and the Affiliated
Companies do not maintain any other defined contribution plan.

12.3   MERGER OF PLAN WITH ANOTHER PLAN:  In the event of any merger or
consolidation of the Plan with, or transfer in whole or in part of the assets
and liabilities of the Trust Fund to another trust fund held under any other
plan of deferred compensation maintained or to be established for the benefit
of all or some of the Members of this Plan, the assets of the Trust Fund
attributable to such Members shall be transferred to the other trust fund only
if:

              (a)    Each Member would (if either this Plan or the other plan
       then terminated) receive a benefit immediately after the merger,
       consolidation or transfer which is equal to or greater than the benefit
       he would have been entitled to receive immediately before the merger,
       consolidation or transfer (if this Plan had then terminated);

              (b)    Resolutions of the Board of Directors of the Employer
       under this Plan, or of any new or successor employer of the affected
       Members, shall authorize such transfer of assets; and, in the case of
       the new or successor employer of the affected Members, its



                                       XII-1
<PAGE>   52
       resolutions shall include an assumption of liabilities with respect to
       such Member's inclusion in the new employer's Plan; and

              (c)    Such other plan and trust are qualified under Code
       Sections 401(a) and 501(a).

13.1   EXPENSES:  Unless paid by the Plan, all costs and expenses incurred in
the administration hereof, including the expenses of the Committee, the fees
and expenses of the Trustee, the fees of counsel, and other administrative
expenses shall be paid by the Plan, unless the Employers voluntarily pay any of
such expenses, in which event they shall be ratably shared by the several
Employers.

13.2   TAXES:  Taxes, if any, on any assets held hereunder by the Trustee, or
upon income therefrom, which are payable by the Trustee, shall be charged
against such assets or income and allocated as the Trustee and the Committee
shall determine.

                           MISCELLANEOUS  PROVISIONS

14.1   TERMS OF EMPLOYMENT:  The adoption and maintenance of the provisions of
this Plan shall not be deemed to constitute a contract between any Employer and
Employee, or to be a consideration for, or an inducement or condition of, the
employment of any person.  Nothing herein contained shall be deemed to give to
any Member the right to be retained in the employ of an Employer or to
interfere with the right of an Employer to discharge a Member at any time, nor
shall it be deemed to give to an Employer the right to require any Member to
remain in its employ, nor shall it interfere with any Member's right to
terminate his employment at any time.

14.2   CONTROLLING LAWS; GOVERNMENT REGULATIONS:  Except to the extent
preempted by applicable federal law, this Plan shall be construed, regulated
and administered under the laws of the State of Texas.  The Plan, and the
purchase and sale of securities pursuant thereto, and the obligations of the
Trustee thereunder to purchase or sell securities, shall be subject to all
applicable laws, rules and regulations, and to such approvals by any
governmental agencies or national securities exchanges as may be required.

14.3   INVALIDITY OF PARTICULAR PROVISIONS:  In the event any provision of this
Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining provisions of this Plan but shall be
fully severable, and this Plan shall be construed and enforced as if said
illegal or invalid provisions had never been inserted therein.

14.4   NON-ALIENABILITY OF RIGHTS OF MEMBERS:  No interest, right or claim in
or to any part of the Trust 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 shall not recognize any attempt to assign, transfer, sell, mortgage,
pledge, hypothecate, commute or anticipate the same.  The foregoing shall also
apply to the creation, assignment, or recognition of a right to any benefit
payable with respect to a Member pursuant to a domestic relations order, unless
such order is determined to be a qualified domestic relations order ("QDRO"),
as defined in Code Section 414(p); provided, however, to the extent directed or
authorized by a QDRO, the Plan may make a distribution prior to a Member's
"earliest retirement age," as defined in Section 414(p) of the Code.

14.5   PAYMENTS IN SATISFACTION OF CLAIMS OF MEMBERS:  Any payment or
distribution to any Member or his legal representative or any beneficiary in
accordance with the provisions of this Plan shall be in full satisfaction of
all claims under the Plan against the Trust Fund, the Trustee and the Employer.
The Trustee may require that any distributee execute and deliver to the Trustee
a receipt and a full and complete release as a condition precedent to any
payment or distribution under the Plan.

14.6   PAYMENTS DUE MINORS AND INCOMPETENTS:  If the Committee determines that
any person to whom a payment is due hereunder is a minor or is incompetent by
reason of physical or mental



                                       XIV-1
<PAGE>   55
disability, the Committee shall have power to cause the payment becoming due
such person to be made to another for the benefit of such minor or incompetent,
without the Committee or the Trustee being responsible to see to the
application of such payment.  Payment made pursuant to such power shall operate
as a complete discharge of the Committee, the Trustee and the Employer.

14.7   ACCEPTANCE OF TERMS AND CONDITIONS OF PLAN BY MEMBERS:  Each Member, by
making application to become a Member under this Plan, or by the execution of
any form authorized under the terms of this Plan for himself, his heirs,
executors, administrators, legal representatives and assigns, approves and
agrees to be bound by the provisions of this Plan and the Trust and any
subsequent amendments thereto, and all actions of the Committee and the Trustee
hereunder.

14.8   IMPOSSIBILITY OF DIVERSION OF TRUST FUND:  Notwithstanding any provision
herein to the contrary, no part of the corpus or the income of the Trust Fund
shall ever be used for, or diverted to, purposes other than for the exclusive
benefit of the Members or their beneficiaries or for the payment of expenses of
the Plan.  Except as otherwise provided in Section 15.9, no part of the Trust
Fund shall ever directly or indirectly revert to the Employer.

14.9   REFUNDS TO EMPLOYER:  Once contributions are made to the Plan by the
Employer on behalf of the Members, they are not refundable to the Employer
unless a contribution:

              (a)    was made by mistake of fact; or

              (b)    was made conditioned upon the contribution being allowed
       as a deduction and such deduction was disallowed.

Any contribution made by the Employer during any Plan Year in excess of the
amount deductible or any contribution attributable to a good faith mistake of
fact shall be refunded to the Employer.  The amount which may be returned to
the Employer is the excess of the amount contributed over the amount that would
have been contributed had there not occurred a mistake of fact or the excess of
the amount contributed over the amount deductible, as applicable.  A
contribution made by reason of a mistake of fact may be refunded only within
one year following the date of payment.  Any contribution to be refunded
because it was not deductible under Code Section 404 may be refunded only
within one year following the date the deduction was disallowed.  Earnings
attributable to any such excess contribution may not be withdrawn, but losses
attributable thereto must reduce the amount to be returned.  In no event may a
refund be due which would cause the Account balance of any Member to be reduced
to less than the Member's Account balance would have been had the mistaken
amount, or the amount determined to be nondeductible, not been contributed.

                              AFFILIATED COMPANIES

15.1   ELIGIBILITY AND ADOPTION:  Any Affiliated Company approved by the Board
of Directors may participate as an Employer in the Plan upon the following
conditions:

              (a)    Such Affiliated Company shall make, execute and deliver
       such instruments and take such other action as the Corporation or the
       Committee shall deem necessary or desirable.

              (b)    Such Affiliated Company shall appoint the Corporation as
       its agent to act for it in all transactions in which the Corporation
       believes such agency will facilitate the administration of the Plan.

                         TOP-HEAVY PLAN REQUIREMENTS

16.1   GENERAL RULE:  For any Plan Year for which this Plan is a Top-Heavy
Plan, as defined in Section 16.6, and despite any other provisions of this Plan
to the contrary, this Plan shall be subject to the provisions of this Article
XVI.

16.2   VESTING PROVISIONS:  Each Member who has completed an Hour of Service
after the Plan becomes top-heavy shall be immediately 100% vested in his
account under this Plan.

16.3   MINIMUM CONTRIBUTION PROVISIONS:  Each Member who (i) is a Non-Key
Employee, and (ii) is employed on the last day of the Plan Year (regardless of
whether the Member has completed 1,000 Hours of Service during the Plan Year,
made a required contribution that year, or his level of compensation), will be
entitled to have contributions and forfeitures allocated to his account of not
less than 3% (the "Minimum Contribution Percentage") of the Member's
Compensation.  This Minimum Contribution Percentage will be reduced for any
Plan Year to the percentage at which contributions (including forfeitures) are
made or are required to be made under the Plan for the Plan Year for the Key
Employee for whom such percentage is the highest for such Plan Year.  If the
Member also participates in a defined benefit plan of the Employer that is top
heavy, he shall receive the minimum under such defined benefit plan rather than
this Plan.

       Contributions considered under the first paragraph of this Section 16.3
will include Employer contributions under this Plan and under all other defined
contribution plans required to be included in an Aggregation Group, but will
not include Employer Contributions under any plan required to be included in
such Aggregation Group if the plan enables a defined benefit plan required to
be included in such group to meet the requirements of the Code prohibiting
discrimination as to contributions in favor of employees who are officers,
shareholders, or the highly compensated or prescribing the minimum
participation standards.  If the highest rate allocated to a Key Employee for a
year in which the plan is top-heavy is less than 3%, amounts contributed as a
result of a salary reduction agreement must be included in determining
contributions made on behalf of Key Employees.

       Contributions considered under this Section will not include any
contributions under the Social Security Act or any other federal or state law.

16.4   LIMITATION ON CONTRIBUTIONS:  In the event that the Company, other
Employer or an Affiliated Company (hereinafter in this Article collectively
referred to as a "Considered Company") also maintains a defined benefit plan
providing benefits on behalf of Members in this Plan, one of the two following
provisions will apply:

              (a)    If, for the Plan Year, this would not be a Top-Heavy Plan
       if "90%" were substituted for "60%", in Section 16.6, then the
       percentage of 3% used in Section 16.3 is changed to 4%.



                                       XVI-1
<PAGE>   58
              (b)    If, for the Plan Year, this Plan would continue to be a
       Top-Heavy Plan if "90%" were substituted for "60%", in Section 16.6,
       then the denominator of both the defined contribution plan fraction and
       the defined benefit plan fraction will be calculated as set forth in
       Section 4.11 for the limitation year ending in such Plan Year by
       substituting "1.0" for "1.25" in each place such figure appears.  This
       subsection (b) will not apply for such Plan Year with respect to any
       individual for whom there are no (i) Employer Contributions, forfeitures
       or voluntary nondeductible contributions allocated to such individual,
       or (ii) accruals earned under the defined benefit plan.

16.5   UNIFORM ACCRUAL:  For Plan Years beginning after December 31, 1986, a
uniform benefit accrual rate must be used in determining whether a plan is top-
heavy or super top-heavy.  If all of the employer's plans accrue benefits at
the same rate, that accrual rate is to be used to determine if its plans are
top-heavy or super top-heavy.  If no single accrual rate is used uniformly by
all of the Employer's plans, the slowest accrual rate permitted under the
fractional method must be used to determine the accrued benefit for Non-Key
Employees.

16.6   DETERMINATION OF TOP-HEAVY STATUS:  The Plan will be a Top-Heavy Plan
for any Plan Year if, as of the Determination Date, the aggregate of the
accounts under the Plan for Members (including former Members) who are Key
Employees exceeds 60% of the aggregate of the accounts of all Members,
excluding former Key Employees, or if this Plan is required to be in an
Aggregation Group in any such Plan Year in which such Group is a Top-Heavy
Group.  In determining Top-Heavy status, if an individual has not performed any
services for any Affiliated Company at any time during the five-year period
ending on the Determination Date, any accrued benefit for such individual and
the aggregate accounts of such individual shall not be taken into account.

       In determining whether this Plan constitutes a Top-Heavy Plan, the
Committee (or its agent) will make the following adjustments:

              (a)    When more than one plan is aggregated, the Committee shall
       determine separately for each plan as of each plan's Determination Date
       the present value of the accrued benefits (for this purpose using the
       actuarial assumptions set forth in the applicable plan) or account
       balance.  The results shall then be aggregated by adding the results of
       each plan as of the Determination Dates for such plans that fall within
       the same calendar year.

              (b)    In determining the present value of the cumulative accrued
       benefit or the amount of the account of any Employee, such present value
       or account will include the amount in dollar value of the aggregate
       distributions made to such employee under the applicable plan during the
       five-year period ending on the Determination Date unless reflected in
       the value of the accrued benefit or account balance as of the most
       recent Valuation Date.  The amounts will include distributions to
       employees representing the entire amount credited to their accounts
       under the applicable plan.



                                       XVI-2
<PAGE>   59
              (c)    Further, in making such determination, such present value
       or such account shall include any rollover contribution (or similar
       transfer), as follows:

                     (1)    If the rollover contribution (or similar transfer)
              is initiated by the Employee and made to or from a plan
              maintained by another Affiliated Company, the plan providing the
              distribution shall include such distribution in the present value
              or such account; the plan accepting the distribution shall not
              include such distribution in the present value or such account
              unless the plan accepted it before December 31, 1983.

                     (2)    If the rollover contribution (or similar transfer)
              is not initiated by the employee or made from a plan maintained
              by another Affiliated Company, the plan accepting the
              distribution shall include such distribution in the present value
              or such account, whether the plan accepted the distribution
              before or after December 31, 1983; the  plan  making the
              distribution shall not include the distribution in the present
              value or such account.

              (d)    In any case where an individual is a Non-Key Employee with
       respect to an applicable plan, but was a Key Employee with respect to
       such plan for any prior Plan Year, any accrued benefit and any account of
       such Employee will be altogether disregarded.  For this purpose, to the
       extent that a Key Employee is deemed to be a Key Employee if he or she
       met the definition of Key Employee within any of the four (4) preceding
       Plan Years, this provision will apply following the end of such period of
       time.

       IN WITNESS WHEREOF, the Corporation has caused these presents to be
executed by its authorized individual, in a number of copies, all of which
shall constitute but one and the same instrument, which may be evidenced by any
such executed copy hereof, this June __, 1998, effective for all purposes as
provided above.

                                SAVINGS PLAN FOR
                      HENDERSON BARGAINING UNIT EMPLOYEES

        Pioneer Chlor Alkali Company, Inc. hereby amends, renames, and restates
the Pioneer Chlor Alkali Company, Inc. Bargaining Unit Savings Investment Plan
effective as of July 1, 1998, unless provided otherwise herein.  The terms and
provisions of the Plan as so amended are as follows:

                                  INTRODUCTION

        The purposes of this Plan are to provide benefits for eligible
Employees through an Employer profit sharing contribution and to promote and
encourage Employees to provide additional security and income for their
retirement through a systematic matching savings program.  However, the
establishment of this Plan shall not be considered as giving any Employee or
any other person any legal or equitable right as against any Employer, the
Committee or the Trustee, or in the assets of the Plan, except and to the
extent that such right is specifically provided for in this Plan.

        This Plan has been adopted for the exclusive benefit of the Members and
their beneficiaries.  So far as possible, this Plan shall be interpreted in a
manner consistent with this intent and with the intention of the Corporation
that this Plan shall satisfy those provisions of ERISA and the Code relating to
qualified employee profit sharing plans with a Code Section 401(k) feature.

        The Plan is hereby amended and completely restated as set forth herein
and all rights and benefits under the Plan shall hereafter be determined under
the terms and provisions hereof.  However, the amendment and restatement of the
Plan hereby shall not operate or be construed to deprive any Member of any
protected benefit, within the meaning of Code Section 411(d)(6) and the
regulations thereunder, he may have had under the Plan as in effect immediately
prior to this amendment.

         CHANGE IN INVESTMENT FUNDS -- RECORDKEEPING TRANSITION PERIOD

        Notwithstanding anything in the Plan to the contrary, in order to
transfer the recordkeeping of the Plan's "old" investment funds to the "new"
investment funds, an Implementation Period (beginning July 1, 1998 and
estimated to last approximately three months) will apply to all Members, other
than employees who join the Plan after July 1, 1998.  During the Implementation
Period, affected Members will not be able to change the investment of their
current contributions or account balances.  Investment elections as in effect
on June 30, 1998 will be temporarily "frozen" and "mapped" into new investment
funds as described in the Company's memorandum to all participants dated May
28, 1998.  In addition, withdrawals or loans may not be made during the
Implementation Period.

                                  DEFINITIONS

        The following words and phrases as used herein shall have the following
meanings unless a different meaning is plainly required by the context:

1.1     ACCOUNT OR ACCOUNTS:  The Employer Contribution Account, the Savings
Contribution Account, the Salary Deferral Contribution Account and/or the
Rollover Account of a Member.

1.2     ACTUAL DEFERRAL PERCENTAGE:  The Actual Deferral Percentage, as defined
in Section 4.6.

1.3     AFFILIATED COMPANY:  Any corporation which is a member of a controlled
group of corporations (within the meaning of the Code Section 414(b)) with the
Corporation; any trade or business (whether or not incorporated) which is under
common control (as defined in Code Section 414(c)) with the Corporation; any
organization (whether or not incorporated) which is a member of an affiliated
service group (as defined in Code Section 414(m)) which includes the
Corporation; and any other entity required to be aggregated with the
Corporation pursuant to Regulations under Code Section 414(o).  For purposes of
applying the limitations of Code Section 415, an Affiliated Company shall be
determined in accordance with Code Section 415(h).

1.4     AGGREGATION GROUP:  For purposes of Article XVI, the group of plans, if
any, that includes both the group of plans required to be aggregated and the
group of plans permitted to be aggregated.  The group of plans required to be
aggregated (the "required aggregation group") includes:

                 (a)     Each plan of an Affiliated Company in which a Key
        Employee is a participant, including collectively bargained plans, and

                 (b)     Each other plan, including collectively bargained
        plans, of an Affiliated Company which enables a plan in which a Key
        Employee is a participant to meet the requirements of the Code, as
        amended, prohibiting discrimination as to contributions or benefits in
        favor of employees who are officers, shareholders, or the highly
        compensated or prescribing minimum participation standards.

        The group of plans that are permitted to be aggregated (the "permissive
aggregation group") includes the required aggregation group plus one or more
plans of an Affiliated Company that is not part of the required aggregation
group, and that the Affiliated Company certifies as a plan within the
permissive aggregation group.  Such plan or plans may be added to the
permissive aggregation group only if, after the addition, the aggregation group
as a whole continues not to discriminate as to contributions or benefits in
favor of officers, shareholders, or the highly compensated, and to meet the
minimum participation standards under the Code.

account of a key employee, as defined in Code Section 419A(d)(3), under a
welfare benefit fund, as defined in Code Section 419(e), maintained by the
Employer, are treated as Annual Additions.

reimbursed by the Employer or Affiliated Company for moving expenses incurred
by the Employee, but only to the extent that these amounts are excludable from

                 (a)     Contributions made by the Employer or Affiliated
        Company to a plan of a deferred compensation to the extent that, before
        the application of the Code Section 415 limitations to that plan, the
        contributions are not includable in the gross income of the Employee
        for the taxable year in which contributed.  In addition, Employer
        contributions made on behalf of an Employee to a simplified employee
        pension described in Code Section 408(k) are not considered as
        compensation for the taxable year in which contributed to the extent
        such contributions are deductible by the Employee under Code Section
        219(b)(7).  Additionally, any distributions from a plan of deferred
        compensation are not considered as compensation for Code Section 415
        purposes, regardless of whether such amounts are includable in the
        gross income of the Employee when distributed.  However, any amounts
        received by an Employee pursuant to an unfunded non-qualified plan may
        be considered as compensation for Code Section 415 purposes in the year
        such amounts are includable in the gross income of the Employee.

                 (b)     Amounts realized from the exercise of a non-qualified
        stock option, or when restricted stock (or property) held by an
        Employee becomes freely transferable or is no longer subject to a
        substantial risk of forfeiture (see Code Section 83 and the regulations
        thereunder).

                 (c)     Amounts realized from the sale, exchange or other
        disposition of stock acquired under a qualified stock option.

                 (d)     Other amounts which receive special tax benefits, such
        as premiums for group term life insurance (but only to the extent that
        the premiums are not includable in the gross income of the Employee),
        or contributions made by an Employer or Affiliated Company (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 excludable from the gross income of the Employee).

Subject to the foregoing exclusions, for purposes of applying the limitations
above, amounts included as Applicable Compensation are those actually paid or
made available to a Member within the Plan Year.

1.8     BOARD OF DIRECTORS:  The Board of Directors of the Corporation.

1.9     BREAK IN SERVICE:  A calendar year during which the Employee is
credited with 500 or less Hours of Service.  For purposes of determining a
Break in Service only, an Employee shall be deemed to have completed Hours of
Service for periods of absence from work (1) by reason of the pregnancy of the
Employee, (2) by reason of the birth of a child of the Employee, (3) by reason
of the placement of a child in connection with the adoption of the child by the
Employee, or (4) for purposes of caring for the child during the period
immediately following the birth or placement for adoption.  During the period
of such absence, the Employee shall be treated as having completed (1) the
number of Hours of Service that normally would have been credited but for the
absence, or (2) if the normal Hours of Service worked are unknown, eight Hours
of Service for each normal workday during the absence.  The total number of
Hours of Service required to be treated as completed for any such period of
absence shall not exceed 501 hours.  Further, such Hours of Service shall be
credited only (1) in the year in which the absence begins for one of the
permitted reasons, if the crediting is necessary to prevent a Break in Service
in that year, or (2) in the following year.

1.10    CODE:  The Internal Revenue Code of 1986, as amended from time to time.

1.11    COMMITTEE:  The administrative committee of the Plan as provided for in

However, annual compensation in excess of $160,000 (as such amount shall be
adjusted as permitted under Code Section 401(a)(17)) shall be disregarded for
purposes of this Plan.  For any Plan Year of less than 12 months, the applicable
dollar limit for such year shall be prorated by dividing the number of full
months in such year by 12.

1.14    CORPORATION:  Pioneer Chlor Alkali Company, Inc., a Delaware
corporation.

1.15    DETERMINATION DATE:  For purposes of any Plan Year, the last day of the

1.17    ELIGIBLE CLASS:  An Employee of an Employer who is a member of, or
covered by, a collective bargaining unit which has a bargaining agreement with
the Employer that provides for the participation of such Employees in the Plan.

1.18    EMPLOYEE:  Any employee of the Corporation or an Affiliated Company
and, to the extent required to be treated as an "employee" for certain Plan
purposes by Code Section 414, any Leased Employee performing services for the
Corporation or an Affiliated Company.  It shall also include, with respect to
an Employer, an employee or former employee who is receiving periodic severance
(but not a lump sum) under a plan, program or agreement of the Employer, to the
extent severance is permitted by applicable regulations under Code Section
401(a)(4) to be treated as imputed service, but such imputed employment shall
not exceed two years.

Companies as from time to time is participating in the Plan, as provided in
Article XV.

1.20    EMPLOYER CONTRIBUTION:  The Employer's matching contributions to the

1.24    EXCESS CONTRIBUTIONS:  Amounts exceeding the Actual Deferral Percentage
limits for Highly Compensated Employees.

1.25    HIGHLY COMPENSATED EMPLOYEE:  Any Employee or former Employee who is a
highly compensated employee as defined in Code Section 414(q).  Generally, any
Employee or former Employee is considered a Highly Compensated Employee if
during the Plan Year or the preceding Plan Year such Employee or former
Employee:

                 (a)     was at any time a "5% owner."  "5% owner" means any
        person who owns (or is considered as owning within the meaning of Code
        Section 318) more than 5% of the outstanding stock of the Employer or
        stock possessing more than 5% of the total combined voting power of all
        stock of the Employer or, in the case of an unincorporated business,
        any person who owns more than 5% of the capital or profits interest in
        the Employer.  In determining percentage ownership hereunder,
        Affiliated Companies that would otherwise be aggregated under Code
        Section 414(b), (c), and (m) shall be treated as separate Employers.

                 (b)     received Total Compensation from the Employer in
        excess of $80,000 (as adjusted by Code Section 415(d)), and

                 (c)     if elected by the Corporation for such preceding year,
        was in the top 20% of the Employees when ranked on the basis of
        Applicable Compensation paid during the previous year.

For purposes of determining whether an Employee is a Highly Compensated
Employee for the Plan Year beginning in 1997, the above definition shall be
treated as having been in effect for the Plan Year beginning in 1996.

1.26    HOUR OF SERVICE:  Each hour for which an Employee is paid, or entitled
to payment, for the performance of duties for the Employer or an Affiliated
Company during the applicable computation period.  An Hour of Service is each
hour for which an Employee is paid, or entitled to payment by the Employer or
an Affiliated Company on account of a period of time during which no duties are
performed, due to vacation, holiday, illness, incapacity (including
disability), layoff, jury duty, military duty or leave of absence.  No more
than 501 hours shall be credited with respect to any single continuous period
during which the Employee performs no duties (whether or not such period occurs
in a single computation period).  An hour for which an Employee is directly or
indirectly paid, or entitled to payment, on account of a period during which no
duties are performed is not required to be credited to the Employee if such
payment is made or due under a plan maintained solely for the purpose of
complying with applicable workmen's compensation, or unemployment compensation
or disability insurance laws; and Hours of Service are not required to be
credited for a payment which solely reimburses an Employee for medically
related expenses incurred by the Employee.  For purposes of this section, a
payment shall be deemed to be made by or due from an Employer regardless of
whether such payment is made by or due from the Employer directly or





                                     I-5
<PAGE>   13
indirectly, through, among others, a trust fund or insurer or other entity to
which the Employer contributes or pays premiums and regardless of whether
contributions made or due to the trust fund, insurer or other entity are for
the benefit of particular employees or on behalf of a group of employees in the
aggregate.  An Hour of Service is also 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 in two periods.
Crediting of Hours of Service for back pay awarded or agreed to shall be with
respect to the periods within which such service was performed.  Hours of
Service shall be credited to computation periods in accordance with the
provisions of Department of Labor Regulation Section 2530.200b.  Instead of
counting and crediting actual hours worked, for purposes of determining the
number of Hours of Service to be credited to an Employee, an Employee may be
credited with 190 Hours of Service for each calendar month during which he has
earned one Hour of Service.  For purposes of determining the number of Hours of
Service to be credited for reasons other than the performance of duties and for
purposes of determining to which computation period Hours of Service earned
under any provision of this Plan are to be credited, the provisions of
Department of Labor Regulation Section 2520.200(b)-2(b) and (c) are hereby
incorporated by reference as if fully set forth herein.

1.28    KEY EMPLOYEE:  Any Employee and former Employee (and any beneficiary of
an Employee under this Plan) 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 amount in effect under Section 415(b)(1)(A) of the
Code as applicable to any Plan Year during the determination period, an owner
(or any Employee considered an owner under Code Section 318) of one of the ten
largest interests in an Affiliated Company (provided such interest is greater
than .5%) if such individual's compensation exceeds 100% of such dollar
limitation amount, a 5% owner of an Affiliated Company, or a 1% owner of an
Affiliated Company who has an annual compensation of more than $160,000 (as
adjusted).  The determination period is the Plan Year containing the
Determination Date and the four preceding Plan Years.  The determination of who
is a Key Employee will be made in accordance with Section 416(i)(1) of the Code
and the regulations thereunder.

1.29    LEASED EMPLOYEE:  Any person who (1) is not a common-law employee of
the Employer and (2) pursuant to an agreement between an Employer and any other
person, has performed services for the Employer (or for the Employer and
related persons determined in accordance with Section 414(n)(6) of the Code) on
a substantially full time basis for a period of at least one year, and such
services are performed under the primary direction or control of the Employer.

1.30    MAXIMUM PERMISSIBLE AMOUNT:  For a Plan Year, the Maximum Permissible
Amount with respect to any Employee shall be the lesser of:

                 (a)     $30,000 (as increased in accordance with Code Section
        415(d) to reflect cost-of-living adjustments).  No adjustment will be
        made until the $30,000 limit is 25% of the





                                     I-6
<PAGE>   14
        defined benefit limit.  The two limits will then rise in tandem, with
        the defined contribution limit set at 1/4 of the defined benefit limit.
        Such adjustments to the limits will be based on cost-of-living
        adjustments in the CPI, or

                 (b)     25% of the Employee's Applicable Compensation for the
        Plan Year.

1.44    TOP-HEAVY GROUP:  The Aggregation Group, if, as of the applicable
Determination Date, the sum of the present value of the cumulative accrued
benefits for Key Employees under all defined benefit plans included in the
Aggregation Group plus the aggregate of the accounts of Key Employees under all
defined contribution plans included in the Aggregation Group exceeds 60% of the
sum of the present value of the cumulative accrued benefits for all employees,
excluding former Key Employees as provided in Section 16.6(d), under all such
defined benefit plans, plus the aggregate accounts for all employees, excluding
former Key Employees as provided in Section 16.6(d), under all such defined
contribution plans.  In determining Top-Heavy status, if an individual has not
performed any services for any Employer or Affiliated Company at any time
during the five-year period ending on the Determination Date, any accrued
benefit for such individual, and the aggregate accounts of such individual
shall not be taken into account.  If the Aggregation Group that is a Top-Heavy
Group is a required aggregation group, each plan in the group will be a
Top-Heavy Plan (as defined in Section 16.6).  If the Aggregation Group that is
a Top-Heavy Group is a permissive aggregation group, only those plans that are
part of the required Aggregation Group will be treated as Top-Heavy Plans.  If

1.50    YEAR OF SERVICE: A Year of Service is a Plan Year in which the Employee
is credited with 1,000 or more Hours of Service.  An Employee shall also be
credited with Years of Service with a predecessor employer to the extent

profits in its sole discretion as provided by Code Section 401(a)(27), provided
the Plan continues to qualify as a profit sharing plan.

3.1     EMPLOYEES ELIGIBLE:  Only Employees who are in the Eligible Class shall
be eligible to actively participate in the Plan, and each such Employee shall
be eligible to make Savings Contributions and/or Salary Deferral Contributions
to the Plan beginning on the first day of the month coincident with or next
following the date on which he first completes an Hour of Service; provided,
however, (1) former Employees who are in the Eligible Class upon the date of
their rehire shall be eligible to participate immediately and (2) Employees who
are in the Eligible Class shall be eligible to make qualifying rollover
contributions to the Plan at any time.  The date an Employee in the Eligible
Class is first eligible to contribute to the Plan (other than a rollover

entirely voluntary.

3.4     TRANSFERS OF EMPLOYMENT:  Transfers of employment between two or more
Employers shall not affect a Employee's membership in the Plan, except as
provided in this Section 3.4.  Any transfer of a Member to employment with a
non-participating Affiliated Company or to an employment classification that is
not in the Eligible Class shall not constitute a termination of service.  Each
such transferred Member shall remain a Member of the Plan and shall retain the
rights and benefits accrued under the Plan prior to the date of such transfer
until his subsequent retirement, termination of service or total withdrawal.
However, each such transferred Member shall not be eligible to make additional

                           CONTRIBUTIONS AND VESTING

4.1     SAVINGS CONTRIBUTIONS:  An Employee in the Eligible Class may authorize
a Savings Contribution, to be effected by payroll deductions, in whole
percentages of not less than 1% and not more than 15% of his Compensation for
such payroll period, subject to Section 4.2.

4.2     SALARY DEFERRAL CONTRIBUTIONS:  Subject to Section 4.8, an Employee in
the Eligible Class may elect a Salary Deferral Contribution rate (in whole
percentages) of not less than 1% and not more than 15% of his Compensation for
any payroll period, to be effected by payroll reductions.  Each such election
of a Salary Deferral Contribution rate shall be made in writing on a salary
reduction election form provided by the Committee at least ten days prior to
the effective date of such election (if not made as of the date service
commences), shall be subject to reduction as provided in Section 4.8, and shall
be subject to such other terms and conditions as the Committee may determine.
The sum of an Employee's Salary Deferral Contribution rate and Savings
Contribution rate may not exceed 15% and, to the extent necessary, a Member's
Savings Contributions shall be reduced first.

                 (a)     A Member's Salary Deferral Contribution made pursuant
        to this Section shall not exceed $10,000 for the taxable year of the
        Member.  This dollar limitation shall be adjusted annually as provided
        in Code Section 415(d) pursuant to Regulations.  The adjusted
        limitation shall be effective as of January 1 of each calendar year.

                 (b)     In the event that the dollar limitation provided for
        in Section 4.2(a) is exceeded, the Committee shall direct the Trustee
        to either (1) distribute such excess amount, and any income (or loss)
        allocable to such amount (as provided in (d) below), to the Member not
        later than the first April 15 following the close of the Member's
        taxable year or (2) to recharacterize such excess amount, and any
        income or (loss) allocable to such amount, as a Savings Contributions
        made by the Member, subject to the further provisions of the Plan
        applicable to Savings Contributions.

                 (c)     In the event that a Member is also a participant in
        (1) another qualified cash or deferred arrangement (as defined in Code
        Section 401(k)), (2) a simplified employee pension (as defined in Code
        Section 408(k)), or (3) a salary reduction arrangement (within the
        meaning of Code Section 3121(a)(5)(D)) and the elective deferrals, as
        defined in Code Section 402(g)(3), made under such other arrangement(s)
        and this Plan cumulatively exceed $10,000 (or such amount adjusted
        annually as provided in Code Section 415(d) pursuant to Regulations)
        for such Member's taxable year, the Member may, not later than March 1
        following the close of his taxable year, notify the Committee in
        writing of such excess and request that his Salary Deferral
        Contribution under this Plan be reduced by an amount specified by the
        Member.  Such amount shall then be distributed in the same manner as
        provided in Section 4.2(b).

<PAGE>   20
                 (d)     The income (or loss) allocable to returnable
        contributions shall equal the sum of the allocable gain or loss for the
        Plan Year and the allocable gain or loss for the period between the end
        of the Plan Year and the date of distribution.  Income includes all
        earnings and appreciation, including such items as interest, dividends,
        rent, royalties, gains from the sale of property, appreciation in the
        value of stocks, bonds, annuity and life insurance contracts, and other
        property, without regard to whether such appreciation has been
        realized.

                         (1)      The income (or loss) allocable to returnable
                 contributions for the Plan Year is determined by multiplying
                 the income (or loss) for the Plan Year allocable to employee
                 contributions, matching contributions, and amounts treated as
                 matching contributions (whichever is applicable) by a
                 fraction.  The numerator of the fraction is the amount of
                 returnable contributions made on behalf of the employee for
                 the Plan Year.  The denominator of the fraction is the total
                 account balance of the employee attributable to employee
                 contributions, matching contributions and amounts treated as
                 matching contributions as of the end of the Plan Year, reduced
                 by the gain allocable to such total amount for the Plan Year
                 and increased by the loss allocable to such total amount for
                 the Plan Year.

                         (2)      The allocable income or loss for the period
                 between the end of the Plan Year and the distribution date is
                 equal to 10 percent of the income or loss allocable to
                 returnable contributions for the Plan Year (as calculated
                 under subparagraph (1) above) multiplied by the number of
                 calendar months that have elapsed since the end of the Plan
                 Year.  For purposes of determining the number of calendar
                 months that have elapsed, a distribution occurring on or
                 before the fifteenth day of the month will be treated as
                 having been made on the last day of the preceding month, and a
                 distribution occurring after such fifteenth day will be
                 treated as having been made on the first day of the next
                 month.

4.3     MATCHING EMPLOYER CONTRIBUTIONS:  Subject to the other provisions of
the Plan, with respect to each payroll period the Employers shall contribute,
with respect to each Member who made Savings Contributions and/or Salary
Deferral Contributions for such pay period, an amount equal to 50% of the sum
of the Member's Savings Contributions and Salary Deferral Contributions for
that payroll period, but only to the extent the sum of such contributions does
not exceed 6% of the Member's Compensation for the applicable payroll period;
provided that, if a Member has made both Savings Contributions and Salary
Deferral Contributions, the Employer Contributions shall be deemed to have been
made first with respect to the Salary Deferral Contributions.

4.4     CHANGE IN CONTRIBUTION RATE:  The Savings Contribution and/or Salary
Deferral Contribution rate elected by a Member may be changed by a Member as of
the first day of any calendar quarter following proper notice in accordance
with Plan administrative procedures, but any such change shall not be
retroactive.





                                     IV-2
<PAGE>   21

4.5     VOLUNTARY SUSPENSION OF CONTRIBUTIONS:  A Member who has elected to
contribute and/or defer a portion of his Compensation as a Savings Contribution
and/or Salary Deferral Contribution under the Plan may suspend any further
contributions and/or deferrals as of the end of any payroll period if, and only
if prior to the end of such payroll period, he gives notice to his Employer, in
such form and manner as the Committee may prescribe, of his election to effect
such suspension.  Such suspension shall remain in effect until the Member again
properly elects to make contributions to the Plan.

4.6     ACTUAL DEFERRAL PERCENTAGE:  For the purposes of this Section, "Actual
Deferral Percentage" means, with respect to the Highly Compensated Employee
group and Non-Highly Compensated Employee group for a Plan Year, the average of
the ratios, calculated separately for each Member in such group, of the amount
of Salary Deferral Contributions allocated to each Member's Salary Deferral
Contribution Account (unreduced by distributions made pursuant to Sections
4.2(b) and 4.2(d)) for such Plan Year, to such Member's Total Compensation for
such Plan Year.

4.7     ACTUAL DEFERRAL PERCENTAGE TEST:

                 (a)     Maximum Annual Allocation: For each Plan Year, the
        annual allocation derived from Salary Deferral Contributions to a
        Member's Salary Deferral Contribution Account shall satisfy one of the
        following tests:

                         (1)      The "Actual Deferral Percentage" for the
                 Highly Compensated Employee group shall not be more than the
                 "Actual Deferral Percentage" of the Non-Highly Compensated
                 Employee group multiplied by 1.25, or

                         (2)      The excess of the "Actual Deferral
                 Percentage" for the Highly Compensated Employee group over the
                 "Actual Deferral Percentage" for the Non-Highly Compensated
                 Employee group shall not be more than two percentage points.
                 Additionally, the "Actual Deferral Percentage" for the Highly
                 Compensated Employee group shall not exceed the "Actual
                 Deferral Percentage" for the Non-Highly Compensated Employee
                 group multiplied by two.  This alternative limitation test
                 cannot be used to satisfy the Actual Deferral Percentage test
                 and the Contribution Percentage Test of Section 4.9, except as
                 otherwise provided by applicable regulations.

                 (b)     For the purposes of  Sections 4.7(a) and 4.8, a Highly
        Compensated Employee and a Non-Highly Compensated Employee shall
        include any Employee eligible to make a deferral election pursuant to
        Section 4.2, whether or not such deferral election was made.

                 (c)     For the purposes of this Section, if two or more plans
        which include cash or deferred arrangements are considered one plan for
        the purposes of Code Section 401(a)(4) or 410(b), the cash or deferred
        arrangements included in such plans shall be treated as one
        arrangement.





                                     IV-3
<PAGE>   22
                 (d)     For the purposes of this Section, if a Highly
        Compensated Employee is a Member under two or more cash or deferred
        arrangements of the Employer, all such cash or deferred arrangements
        shall be treated as one cash or deferred arrangement for the purpose of
        determining the deferral percentage with respect to such Highly
        Compensated Employee.

                 (e)     Notwithstanding the above, the determination and
        treatment of Salary Deferral Contributions and the "Actual Deferral
        Percentage" of any Member shall satisfy such other requirements as may
        be prescribed by the Secretary of the Treasury.

4.8     ADJUSTMENTS AS A RESULT OF ACTUAL DEFERRAL PERCENTAGE TEST:  In the
event that the initial allocations of the Salary Deferral Contributions made
pursuant to the Plan do not satisfy one of the tests set forth in Section
4.7(a), either of the following actions shall be taken:

                 (a)     On or before the 15th day of the third month following
        the end of each Plan Year, but in no event later than the close of the
        following Plan Year, the Committee shall direct the Trustee to
        distribute to the Highly Compensated Employee group the aggregate
        amount of excess Salary Deferral Contributions (and any income
        allocable to such contributions as provided in (d) of Section 4.2),
        beginning with the Member(s) having the highest dollar amount of Salary
        Deferral Contributions, reducing such Members' contributions pro rata
        to the next highest dollar amount of Salary Deferral Contributions (and
        continuing with the next highest group and so on) until the aggregate
        excess amount is distributed.

                 (b)     Within 30 days after the end of the Plan Year, the
        Employer shall make a contribution on behalf of Non-Highly Compensated
        Employees in an amount sufficient to satisfy one of the tests set forth
        in Section 4.7(a).  Such contribution shall be deemed a Salary Deferral
        Contribution and allocated to the Salary Deferral Contribution Account
        of each Non-Highly Compensated Employee in the same proportion that
        each Non-Highly Compensated Employee's Salary Deferral Contribution for
        the year bears to the total Salary Deferral Contributions of all
        Non-Highly Compensated Employees.  However, if option (b) is elected,
        then in all events such contributions shall be fully vested when made
        and shall be subject to the same distribution restrictions that apply
        to Salary Deferral Contributions, except that such amounts may not be
        withdrawn prior to the Member's termination of employment.

                 (c)     The amount of excess Salary Deferral Contributions to
        be distributed or recharacterized shall be reduced by excess deferrals
        previously distributed for the taxable year ending in the same Plan
        Year and excess deferrals to be distributed for a taxable year will be
        reduced by excess contributions previously distributed or
        recharacterized for the Plan beginning in such taxable year.

        4.9      MAXIMUM CONTRIBUTION PERCENTAGE.

                 (a)     The "Contribution Percentage" for the Highly
        Compensated Employee group shall not exceed the greater of:

                         (1)      125% of such percentage for the Non-Highly
                 Compensated Employee group; or

                         (2)      the lesser of 200% of such percentage for the
                 Non-Highly Compensated Employee group, or such percentage for
                 the Non-Highly Compensated Employee group plus two percentage
                 points or such lesser amount determined pursuant to
                 Regulations to prevent the multiple use of this alternative
                 limitation with respect to any Highly Compensated Employee.

                 (b)     For the purposes of this Section and Section 4.10,
        "Contribution Percentage" for a Plan Year means, with respect to the
        Highly Compensated Employee group and Non-Highly Compensated Employee
        group, the average of the ratios (calculated separately for each Member
        in each group) of:

                         (1)      the sum of the matching contributions
                 pursuant to Section 4.3 and Employee Savings Contributions
                 pursuant to Section 4.1 contributed under the Plan on behalf
                 of each such Member for such Plan Year; to

                         (2)      the Member's Total Compensation for such Plan
                 Year.

                 (c)     The "Contribution Percentage" for a Highly Compensated
        Employee shall be determined by aggregating the matching contributions
        pursuant to Section 4.3 and Employee Savings Contributions pursuant to
        Section 4.1 for such Member and dividing the same by the Member's Total
        Compensation.

                 (d)     For purposes of this Section, if two or more plans of
        the Employer to which matching contributions, Employee contributions,
        or elective deferrals are made are treated as one plan for purposes of
        Code Section 410(b), such plans shall be treated as one plan for
        purposes of this Section 4.9.  In addition, if a Highly Compensated
        Employee participates in two or more plans described in Code Section
        401(a) or arrangements described in Code Section 401(k) which are
        maintained by the Employer to which such contributions are made, all
        such contributions shall be aggregated for purposes of this Section
        4.9.

                 (e)     For purposes of Section 4.9(a) and 4.10, a Highly
        Compensated Employee and Non-Highly Compensated Employee shall include
        any Employee eligible to have matching contributions pursuant to
        Section 4.3 and Employee Savings Contributions pursuant to Section 4.1
        allocated to his account for the Plan Year.

4.10    ADJUSTMENTS FOR EXCESSIVE CONTRIBUTION PERCENTAGE:

                 (a)     In the event that the "Contribution Percentage" for
        the Highly Compensated Employee group exceeds the "Contribution
        Percentage" for the Non-Highly Compensated Employee group pursuant to
        Section 4.9(a), the Committee (on or before the 15th day of the third
        month following the end of the Plan Year, but in no event later than
        the close of the following Plan Year) the Committee shall direct the
        Trustee to distribute to the Highly Compensated Employee group the
        amount of "Excess Aggregate Contributions" (and any income allocable to
        such contributions as provided in (d) of Section 4.2), beginning with
        the Member(s) with the highest dollar amount of such contributions,
        reducing such Members' contributions pro rata to the next highest
        dollar amount of contributions (and continuing with the next highest
        group and so on) until the aggregate amount of such excess is
        distributed.  However, no forfeiture may be allocated to a Highly
        Compensated Employee whose contributions are reduced pursuant to this
        Section.

                 (b)     The determination of the amount of "Excess Aggregate
        Contributions" with respect to any Plan Year shall be made after:

                         (1)      first determining the excess contributions
                 pursuant to Section 4.2(a), and

                         (2)      then determining the excess annual
                 allocations pursuant to Section 4.7(a).

                 (c)     To prevent the multiple use of the alternative methods
        of compliance with the ADP test and the ACP test, the provision of
        section 1.401(m)-2 of the regulations are hereby incorporated by
        reference to determine if such multiple use exists.  If, after
        application of such test, multiple use exists, the actual contribution
        percentage shall be reduced as provided in section 1.401(m)-2(c) of the
        regulations for all Highly Compensated Employees in the Plan.

                 (d)     Notwithstanding anything in the Plan to the contrary,
        an employer matching contribution may be distributed only if such
        contribution is an excess aggregate contribution.  It may not be
        distributed merely because it relates to an excess deferral, an excess
        contribution or an excess aggregate contribution that is distributed.
        In such cases, the related matching contribution shall be forfeited
        notwithstanding anything in the Plan to the contrary.

4.11    MAXIMUM ANNUAL ADDITIONS:  Notwithstanding anything contained herein to
the contrary, the total Annual Additions made to Accounts of a Member for any
Plan Year shall be subject to the following limitations:





                                     IV-6
<PAGE>   25
                 (a)     Single Defined Contribution Plan

                                (1)      If an Employer does not maintain any 
                         other qualified plan, the amount of Annual Additions
                         which may be allocated under this Plan on a Member's
                         behalf for a Plan Year shall not exceed the lesser of
                         the Maximum Permissible Amount or any other limitation
                         contained in this Plan.

                                (2)      Prior to the determination of the 
                         Member's actual Applicable Compensation for a Plan
                         Year, the Maximum Permissible Amount may be determined
                         on the basis of the Member's estimated annual
                         Applicable Compensation for such Plan Year.  Such
                         estimated annual Applicable Compensation shall be
                         determined on a reasonable basis and shall be uniformly
                         determined for all Members similarly situated.

                                (3)      As soon as is administratively 
                         feasible after the end of the Plan Year, the Maximum
                         Permissible Amount for such Plan Year shall be
                         determined on the basis of the Member's actual
                         Applicable Compensation for such Plan Year.

                                (4)      If there are Excess Annual Additions 
                         with respect to a Member for the Limitation Year, such
                         Excess Annual Additions shall be disposed of as
                         follows:

                                         A.      There shall first be returned 
                                to the Member his unmatched Savings
                                Contributions (and earnings thereon), if any,
                                and then a portion of his matched Savings
                                Contributions (and earnings thereon), to the
                                extent, and only to the extent, such returned
                                Savings Contributions would reduce the Excess
                                Annual Additions.

                                         B.      If any of such Excess Annual
                                Additions shall then remain, the Employer
                                Contributions, including both Salary Deferral
                                Contributions defined in Section 4.2 and
                                matching Employer Contributions defined in
                                Section 4.3, allocated to the Member (and
                                earnings thereon) shall then be reduced to the
                                extent necessary to eliminate such remaining
                                Excess Annual Additions.  The amount of the
                                reduction of the Employer Contributions for such
                                Member shall be reallocated first out of such
                                Member's unmatched Salary Deferral
                                Contributions, then matching Employer
                                Contribution Account and then out of his Salary
                                Deferral Contribution Account, and shall be held
                                in a suspense account which shall be applied as
                                a part of (and to reduce to such extent what
                                would otherwise be) the matching Employer
                                Contributions for all Members required to be
                                made to the Plan during the next subsequent
                                calendar quarter or quarters.  No portion of
                                such Excess Annual Additions may be distributed
                                to Members or former Members.  If a suspense
                                account is in existence at any time during the
                                Plan Year pursuant to

<PAGE>   26
                                this paragraph B, such suspense account shall
                                not participate in the allocation of investment
                                gains or losses of the Trust Fund.

                 (b)      Two or More Defined Contribution Plans
 
                                (1)      If, in addition to this Plan, the 
                          Employer maintains any other qualified defined
                          contribution plan, the amount of Annual Additions
                          which may be allocated under this Plan on a Member's
                          behalf for a Plan Year, shall not exceed the lesser
                          of:

                                         A.      the Maximum Permissible Amount,
                                reduced by the sum of any Annual Additions
                                allocated to the Member's accounts for the same
                                Plan Year under such other defined contribution
                                plan or plans; or

                                         B.      any other limitation contained
                                in this Plan.

                                (2)      Prior to the determination of the 
                          Member's actual Applicable Compensation for the Plan
                          Year, the amount referred to in Section 4.11(b)(1),
                          may be determined on the basis of the Member's
                          estimated annual Applicable Compensation for such Plan
                          Year.  Such estimated annual Applicable Compensation
                          shall be determined on a reasonable basis and shall be
                          uniformly determined for all Members similarly
                          situated.

                                (3)      As soon as is administratively 
                          feasible after the end of the Plan Year, the amounts
                          referred to in Section 4.11(b)(1) shall be determined
                          on the basis of the Member's actual Applicable
                          Compensation for such Plan Year.

                                (4)      If a Member's Annual Additions under 
                          this Plan and all such other defined contribution
                          plans result in Excess Annual Additions, such Excess
                          Annual Additions shall be deemed to consist of the
                          amounts last allocated.

                                (5)      If Excess Annual Additions were 
                          allocated to a Member on an allocation date of another
                          plan, the Excess Annual Additions attributed to this
                          Plan will be the product of:

                                         A.      the total Excess Annual 
                                Additions allocated as of such date (including
                                any amount which would have been allocated but
                                for the limitations of Code Section 415); times

                                         B.      the ratio of (A) the amount 
                                allocated to the Member as of such date under
                                this Plan, divided by (B) the total amount
                                allocated as of such date under all qualified
                                defined contribution plans (determined without
                                regard to the limitations of Code Section 415).

                          (6)      Any Excess Annual Additions attributed to 
                 this Plan shall be disposed of as provided in Section 4.11(a).

        (c)      Defined Contribution Plan and Defined Benefit Plan

                         (1)      General Rule - If the Employer maintains one
                 or more defined contribution plans and one or more defined
                 benefit plans, the sum of the "defined contribution plan
                 fraction" and the "defined benefit plan fraction," as defined
                 in Code Section 415, cannot exceed 1.0 for any Plan Year.  For
                 purposes of this paragraph (c) of Section 4.11, Employee
                 contributions to a qualified defined benefit plan are treated
                 as a separate defined contribution plan, and all defined
                 contribution plans of an Employer are to be treated as one
                 defined contribution plan and all defined benefit plans of an
                 Employer are to be treated as one defined benefit plan whether
                 or not such plans have been terminated.

                         (2)      If the sum of the defined contribution plan 
                 fraction and defined benefit plan fraction exceeds 1.0, the
                 annual benefit of the defined benefit plan or plans (starting
                 with this Plan first) will be reduced so that the sum of the
                 fractions will not exceed 1.0.  In no event will the annual
                 benefit be decreased below the amount of the accrued benefit to
                 date.  If additional reductions are required for the sum of the
                 fractions to equal 1.0, the reductions will then be made to the
                 defined contribution plan or plans (starting with this Plan
                 first).

        (d)      Incorporation by Reference

                         All provisions of Code Section 415 that may not be
                 applied in more than one manner are hereby incorporated in the
                 Plan by references and if any such incorporated provision
                 conflicts with a provision in the Plan, such incorporated
                 provision shall control.

4.12    ROLLOVER CONTRIBUTIONS:  An Employee who is in the Eligible Class shall
be eligible to make a rollover contribution (whether a "direct" or "indirect"
rollover) to the Plan by wire transfer or by check or other property acceptable
to the Committee, provided such contribution satisfies the requirements of
Section 402(a) of the Code as being a 'qualified rollover,' and the Employee
satisfies such other administrative requirements concerning such rollover
contributions as may be required, including designating the investment fund(s)
for such contribution.  Rollover contributions are not subject to an Employer
matching contribution.

4.13    VESTING:  Each person who was a Member or an Employee in the Eligible
Class on June 30, 1998 shall always be 100% vested in all of his Accounts,
except that any Member in the Tacoma Plan who was not an Employee on the date
it was merged into the Plan, shall continue to be vested in his merged Accounts
only to the extent vested therein on the merger date, unless he again becomes
an Employee.  Each person who becomes a Member after June 30, 1998 shall always
be





                                     IV-9
<PAGE>   28
100% vested in his Savings Contributions, Salary Deferral and Rollover
Accounts, and shall become 100% vested in his Employer Contribution Account
based on his Years of Service in accordance with the following schedule:

<TABLE>
<CAPTION>
         Years of Service                          Vested Percentage
         ----------------                          -----------------
        <S>                                       <C>

            less than 3                                     0%
             3 or more                                    100%
</TABLE>

        Regardless of his Years of Service however, a Participant who is an
Employee on or after reaching age 65 shall be 100% vested in all his Accounts.
Further, in the event a Participant's employment with the Employers and
Affiliated Companies is terminated by reason of disability (as determined for
purposes of Title II of the Federal Social Security Act) or death, he shall
also be deemed to be 100% vested in all his Accounts.

        Notwithstanding the foregoing schedule, in the event the Plan is
terminated or partially terminated or the Employers' contributions under the
Plan are completely discontinued, each affected Member shall thereupon be 100%
vested in all his Accounts as of the date of such discontinuance or termination
or partial termination.

                                  INVESTMENTS

5.1     DIRECTION OF INVESTMENTS:

                 (a)     Each Member shall direct, when he authorizes Savings
        Contributions, elects to have made Salary Deferral Contributions or
        makes a Rollover Contribution, that such contributions be invested in
        one or more of the investment funds offered under the Plan (as set
        forth on Attachment A, which is made a part of the Plan for all
        purposes) in increments of 1%; provided, however, a Rollover
        Contribution may not be invested in the Company Stock Fund.  Employer
        matching contributions shall be invested in the same manner as the
        Member's contributions with respect to which they are made.  The
        Committee may, from time to time, add additional investment funds
        and/or delete existing investment funds offered under the Plan by
        giving advance notice to the Members.  The Committee shall have the
        full power and authority to make such rules as necessary or appropriate
        to add or delete a fund, including amending the Plan and Trust to
        effectuate such change.

                 (b)     Each Member may change the investment of the existing
        balances in his Accounts, by authorizing a transfer from one investment
        fund to one or more of the other investment funds in 1% increments, as
        of any Valuation Date by giving notice to the Plan's record keeper in
        accordance with the Plan's administrative procedures then in effect;
        provided, however, existing Account balances may not be transferred
        into the Company Stock Fund.

                 (c)     Each Member may change the current investment
        direction concerning his future Savings and Salary Deferral
        Contributions as of any Valuation Date by giving notice to the Plan's
        record keeper in accordance with the Plan's administrative procedures
        then in effect.

5.2     COMPANY STOCK FUND:  With respect to the Company Stock Fund, the
Trustee shall vote the shares of Company Stock held in the Company Stock Fund
for the respective Accounts of the Members in accordance with the directions of
such Members, provided such directions are received by the Trustee at least
five days before the date set for the meeting at which such shares are to be
voted.  The Trustee shall not vote shares of Company Stock for which it has not
received timely instructions on a particular matter, unless otherwise required
by ERISA.  Each Member (or, in the event of his death, his beneficiary) shall
have the right, to the extent of the number of shares of Company Stock
allocated to his Accounts in the Company Stock Fund, respectively, to instruct
the Trustee in writing as to the manner in which to respond to a tender offer
or exchange offer with respect to such shares.  The Committee shall use its
best efforts timely to distribute or cause to be distributed to each Member (or
beneficiary thereof) such information as will be distributed to stockholders of
the Company in connection with any such tender offer or exchange offer.  Upon
timely receipt of such instructions, the Trustee shall respond as instructed
with respect to shares of such stock.  The instructions received by the Trustee
from Members shall be held by the Trustee in





                                     V-1
<PAGE>   30
confidence and shall not be divulged or released to any person, including
officers or employees of the Corporation or any Affiliated Company.  If the
Trustee shall not receive timely instructions from a Member (or beneficiary
thereof) as to the manner in which to respond to such tender offer or exchange
offer, such Member (or beneficiary) shall be deemed to have instructed the
Trustee not to tender or exchange the Company Stock.

                   PAYMENT OF CONTRIBUTIONS  AND  ALLOCATIONS

6.1     PAYMENT OF CONTRIBUTIONS:  Each Employer shall, as soon as reasonably
practicable following each payroll period, pay to the Trustee the amounts
representing payroll deductions pursuant to Savings Contributions and the
amounts representing salary reductions pursuant to its Members Salary Deferral
Contributions.  Employer Contributions shall be made to the Trustee in full
prior to the due date including extensions thereof, for filing the Employer's
federal income tax return for its taxable year which ends coincident with the
end of such Plan Year or within which such Plan Year ends, as the case may be.
The Trustee shall hold or apply the contributions so received by it in
accordance with the provisions of the Plan; and no part thereof shall be used
for any purpose other than the exclusive benefit of the Members or their
beneficiaries. Contributions shall be made in cash (by check or wire transfer)
or, with respect to Employer Contributions to be invested in the Company Stock
Fund, in the sole discretion of the Corporation, in shares of Company Stock.

6.2     VALUATION OF TRUST FUND: The Trustee shall value the assets of the
Trust Fund at fair market value as of each Valuation Date.  With respect to an
Account (or the portion thereof) that is invested in a mutual fund, the fair
market value shall be determined based on the reported value of a unit in such
fund for the applicable Valuation Date.  With respect to an Account (or the
portion thereof) that is invested in the Company Stock Fund, the fair market
value shall be the fair market value of the shares of Company Stock allocated
to such Account on the applicable Valuation Date.  The Trustee's determination
of the value of any Account shall be final and conclusive for all purposes of
the Plan.

6.3     FUNDING POLICY: The provisions of Articles IV and VI shall be deemed
the procedure for establishing and carrying out the funding policy and method
of the Plan.  Such funding policy and method shall be administered by the
Employers and other fiduciaries consistent with the objectives of the Plan and
with the requirements of Title I of ERISA.

                           DISTRIBUTION  OF  ACCOUNTS

7.1     TIME OF DISTRIBUTION:  For separations from service occurring after
1997, if the vested value of the Member's Accounts is less than or equal to
$5,000 (for separations from service prior to 1998, $3,500 shall be substituted
for $5,000 here and below, unless IRS rules permit the $5,000 limit to apply to
such Members), distribution of the Member's Accounts shall be made as soon as
practicable after the Member's separation from service; however, if the total
vested value of the Member's Accounts exceeds (or at the time of any prior
withdrawal or distribution, exceeded) $5,000, the Member's Accounts shall be
distributed only upon his written consent following his separation of service,
but in any event no later than 60 days after the end of the Plan Year in which
occurs the earlier of the Member's death or attainment of age 65.  If a
Member's termination of service occurs after attainment of age 65, distribution
shall be made within 60 days after the end of the Plan Year in which
termination occurs; however, Effective January 1, 1997, benefit payments to any
Member who reaches age 70-1/2 prior to 1999 (excluding any 5% or more owner)
must begin by April 1 of the calendar year following the year in which the
individual attains age 70-1/2, whether or not the person has terminated
service, unless such Member (excluding any 5% or more owner) elects to defer
distribution until his termination of employment.  All benefits payable because
of a Member's death shall be paid to the Member's beneficiary in a single,
lump-sum distribution as soon as practicable and in all events within five
years of the Member's date of death.  If a Member dies after distributions have
begun following his termination of employment and before his entire interest
has been distributed to him, the remaining portion will be distributed to his
beneficiary at least as rapidly as the method in effect on the Member's date of
death.

        Notwithstanding anything in the Plan to the contrary, amounts held in
the Member's Salary Deferral Contribution Account may not be distributable
prior to the earlier of:

                 (a)     his separation from service (within the meaning of
        Code Section 401(k)), total and permanent disability, or death;

                 (b)     his attainment of age 59-1/2;

                 (c)     termination of the Plan without establishment of a
        successor plan by the Employer or an Affiliated Company;

                 (d)     the date of the sale by the Employer to an entity that
        is not an Affiliated Company of substantially all of the assets (within
        the meaning of Code Section 409(d)(2)) with respect to a Member who
        continues employment with the corporation acquiring such assets;
        provided the Employer continues to maintain the Plan;

                 (e)     the date of the sale by the Employer of its interest
        in a subsidiary (within the meaning of Code Section 409(d)(3)) to an
        entity which is not an Affiliated Company with





                                    VII-1
<PAGE>   33
        respect to a Member who continues employment with such subsidiary;
        provided the Employer continues to maintain the Plan; or

                 (f)     proven financial hardship, subject to the limitations
        of Section 7.6, and any distribution due to items (c), (d) or (e) above
        may only be made in a lump sum.

7.2     DISTRIBUTIONS FROM ACCOUNTS FOLLOWING SEPARATION FROM SERVICE:
Following a Member's separation from service, his Accounts shall be distributed
as follows: subject to Section 7.8, the Member's Accounts shall be distributed
to the Member or his beneficiary, as the case may be, in a lump sum payment in
cash or, with respect to the portion of the Account invested in the Company
Stock Fund, if any, in shares of Company Stock, if elected.

7.3     PARTIAL WITHDRAWALS:

                 (a)     Pre-1987 Member Contribution Withdrawals.  As of any
        Valuation Date, a Member who is an Employee may, by giving proper
        notice, elect to withdraw from such Member's Pre-1987 Savings
        Contributions Subaccount under his Savings Contribution Account any
        dollar amount of such contributions without investment earnings
        thereon.  The amount withdrawn may not exceed the amount of such
        contributions made prior to 1987.

                 (b)     Post-1986 Member Contribution Withdrawals.  A Member
        who is an Employee and who has withdrawn all the funds available (if
        any) pursuant to (a) above may, as of any Valuation Date, by giving
        proper notice, elect to withdraw from such Member's Savings
        Contributions Account all or any part of such Account.

                 (c)     Rollover Account Withdrawals.  A Member who is an
        Employee and has withdrawn all funds available (if any) pursuant to (a)
        and (b) above may, as of any Valuation Date, by giving proper notice,
        elect to withdraw all or any part of such Member's Rollover Account.

        Withdrawals shall be in cash unless the Account is invested in the
Company Stock Fund and the Member elects to withdraw shares.

        If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.4     TOTAL WITHDRAWAL:  A Member who is an Employee and who withdraws all
funds available pursuant to Section 7.3 may, as of any Valuation Date, by
giving proper notice, elect to withdraw from such Member's Employer
Contributions Account all or any part of the vested portion of such Member's
Employer Contributions Account; provided, however, a Member may make such a
withdrawal only if he has been a Member for at least 60 months prior to date of
such withdrawal.





                                    VII-2
<PAGE>   34
A Member who makes a withdrawal pursuant to this Section shall not be entitled
to Employer matching contributions with respect to any Savings or Salary
Deferral Contributions he may make during the following 6-month period.
Withdrawals shall be in cash unless the Account is invested in the Company
Stock Fund and the Member elects to withdraw shares.

        If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.5     SPECIAL WITHDRAWAL AFTER ATTAINMENT OF AGE 59-1/2:  Each Member who is
an Employee, is fully vested, and has attained age 59-1/2 may withdraw all or
any portion of his Employer Contribution Account, and, even if not fully
vested, his Salary Deferral Contribution Account as of any Valuation Date by
giving proper notice of such withdrawal.  Withdrawals shall be in cash unless
the Account is invested in the Company Stock Fund and the Member elects to
withdraw shares.

        If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.6     HARDSHIP WITHDRAWALS:  A Member who is an Employee may request for a
hardship withdrawal from his Salary Deferral Contribution Account and, if fully
vested, his Employer Contribution Account.  The approval or disapproval of such
request shall be made by the Committee.  The Committee shall not approve any
such request unless it finds that the Member is facing a hardship creating an
"immediate and heavy financial need" (as defined below) and the Member has
obtained all distributions, other than hardship distributions, and all
nontaxable loans currently available under the Plan and all other plans of the
Employer and its ERISA affiliates.  To the extent the Member is fully vested in
his Employer Contribution Account, the withdrawal shall be taken first from
that Account.  The amount of the hardship withdrawal shall be limited to an
amount that does not exceed:  (1) that amount which the Committee determines to
be required to meet the immediate financial needs created by the hardship,
which may include any amounts necessary to pay any federal, state or local
income taxes or penalties reasonably anticipated to result from the
distribution, and (2) if made from the Participant's Salary Deferral
Contribution Account, the amount of the Salary Deferral Contribution Account,
but excluding all earnings credited to such Account after 1988.  Further, if a
hardship distribution is made under the Plan, the restrictions set forth in
subparagraph (b) below shall apply.  The hardship withdrawal shall be made in
cash as soon as practical after the date the Member submitted the hardship
request.  The following standards shall be applied on a uniform and
non-discriminatory basis in determining the existence of a hardship:

                 (a)     A financial need shall be deemed to be an "immediate
        and heavy financial need" if it is on account of:

                         (1)      Medical expenses described in section 213(d)
                 of the Code incurred by the Member, the Member's spouse, or
                 any dependents of the Member (as defined in section 152 of the
                 Code) or necessary for these persons to obtain such medical
                 care;

                         (2)      Costs directly related to the purchase
                 (excluding mortgage payments) of a principal residence for the
                 Member;

                         (3)      Payment of tuition, related educational fees,
                 and room and board expenses for the next 12 months of
                 post-secondary education for the Member, his or her spouse,
                 children, or dependents; or

                         (4)      The need to prevent the eviction of the
                 Member from his principal residence or foreclosure on the
                 mortgage of the Member's principal residence; or

                         (5)      any other "safe-harbor" event established
                 from time to time by the Internal Revenue Service.

                 (b)     Upon a hardship distribution,

                         (1)      The Member's 401(k) contributions and
                 after-tax contributions under the Plan, and all other plans
                 maintained by the Employer and its ERISA affiliates (other
                 than a health or welfare benefit plan or the mandatory
                 employee contribution portion of a defined benefit plan), will
                 be suspended for 12 months, and

                         (2)      The Member may not make 401(k) contributions
                 under the Plan, and all other plans maintained by the Employer
                 and its ERISA affiliates, for the Member's taxable year
                 immediately following the taxable year of the hardship
                 distribution in excess of the applicable limit under Code
                 Section 402(g) for such next taxable year less the amount of
                 the Member's elective contributions for the taxable year of
                 the hardship distribution.

        Withdrawals shall be in cash unless the Account is invested in the
Company Stock Fund and the Member elects to withdraw shares.

        If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.7     LOANS TO MEMBERS:  Loans shall be granted in a uniform and
non-discriminatory manner to Members (as used herein, a Member includes a
beneficiary) from their Accounts, provided the Member is a "party in interest"
under ERISA, subject to the following terms and conditions:





                                    VII-4
<PAGE>   36
                 (a)     Loans made pursuant to this Section (when added to the
        outstanding balance of all other loans made by the Plan to the Member)
        shall be limited to the lesser of:

                         (1)      $50,000 reduced by the excess (if any) of the
                 highest outstanding balance of loans from the Plan to the
                 Member during the one-year period ending on the day before the
                 date on which such loan is made, over the outstanding balance
                 of loans from the Plan to the Member on the date on which such
                 loan was made, or

                         (2)      one-half of the value of the vested portion
                 of the Member's Accounts.

        For purposes of this limit, all plans of the Employer and Affiliated
        Companies shall be considered one plan.  Each loan must be for at least
        $1,000.

                 (b)     Loans shall provide for the level amortization of
        principal and interest with payments to be made not less frequently
        than monthly over a period not to exceed five years.  However, loans
        used to acquire any dwelling unit which, within a reasonable time, is
        to be used (determined at the time the loan is made) as a principal
        residence of the borrower shall provide for periodic repayment over a
        period of time not to exceed ten years.  Loans shall be evidenced by a
        note signed by the Member payable in monthly installments.  All loans
        shall bear interest at the rate in effect in the commercial loan
        division of the Trustee or an affiliated bank to the Trustee for loans
        of a similar nature on the date the loan is made, and if the Trustee
        does not provide such a rate of interest itself or through an
        affiliated bank, then the rate at any bank handling the Company's
        accounts as determined by the Committee, for loans of a similar nature
        on the date the loan is made.

                 (c)     Loans must be repaid by means of an irrevocable
        payroll deduction election, unless the Member is not receiving a salary
        from the Employer that is sufficient to allow deduction of the full
        loan payments, in which case any excess of payments due over the amount
        deductible from the Member's salary shall be paid to the Plan by the
        Member in level installments each pay period, but in no event less
        frequently than monthly.  All loans shall become due and payable in
        full upon the date a Member ceases to be a "party in interest" to the
        Plan.

                 (d)     Loans shall be made first from the Rollover Account,
        then the Salary Deferral Contribution Account.  If the balance in the
        Salary Deferral Contribution Account is less than the amount of the
        requested loan, the remainder of the loan shall be made next from the
        Employer Contribution Account, and last from the Savings Contribution
        Account.  Any loan under the Plan shall be secured by the pledge of all
        of the Member's right, title and interest in an amount of his or her
        vested Accounts equal to the amount of the loan, but not exceeding 50%
        of such vested Accounts as determined immediately after such loan.
        Such pledge shall be executed by the Member and his Spouse, if any,
        which shall provide that, in the event of any default on a loan
        repayment, the Committee shall be authorized to take any and all
        appropriate lawful actions necessary to enforce collection of the
        unpaid loan.  In





                                    VII-5
<PAGE>   37
        addition, the promissory note shall provide that, in the event of a
        default on the loan repayment, both the principal and accrued, unpaid
        interest shall be immediately due and payable.  If the Member is
        subject to the provisions of Section 401(a)(11) of the Code at the time
        the vested Accounts are pledged as  security for the loan, the spousal
        consent must be obtained in the proper form.

                 (e)     A request for a loan shall be made in accordance with
        the Plan's administrative procedures, which may specify the order in
        which the investment fund(s) within each of the Account(s) are invested
        shall be redeemed to make the requested loan, and shall constitute a
        written consent to a distribution or deemed distribution of the
        Account(s), if necessary, in the event of a default.  If a request for
        a loan is approved by the Committee, the Committee shall furnish or
        cause to be furnished the Trustee with instructions directing the
        Trustee to make the loan in a lump-sum payment of cash to the Member.

                 (f)     A loan shall be considered an investment of the
        separate Account(s) of the Member from which the loan is made.  All
        loan repayments of principal and interest shall be credited to such
        separate Account(s) and reinvested in the investment funds in
        accordance with the Member's election in effect for his current
        contributions, or, if none is in effect, his most recent such election.

                 (g)     Only two loans may be outstanding at any time to a
        Member.

                 (h)     Loan repayments will be suspended under this Plan as
        permitted under Code Section 414(u)(4).

                 (i)     All or part of the reasonable administrative costs of
        establishing and maintaining a loan may be charged to the borrowing
        Member.

7.8     METHODS OF DISTRIBUTION:  Distributions shall be made in a lump sum in
cash (and, with respect to Accounts invested in the Company Stock Fund, in
shares of Company Stock, if elected) unless a Member (and his Spouse, if
applicable) have made the proper election to receive one of the following
optional forms of payment.

                 (a)     Joint and Survivor Annuity.  If a Member is married on
        the benefit payment date and elects not to receive a lump sum,
        distribution shall be in the form of a Joint and Survivor Annuity,
        which shall be an annuity for the life of the Member with a contingent
        annuity for the life of the Member's Spouse, if she survives him, which
        is 50% of the amount of the annuity payable to the Member had he lived.
        The Joint and Survivor Annuity shall be maximum amount that may be
        obtained by purchasing an annuity contract with the Member's Accounts
        from an insurance company selected by the Committee.  Subject to
        Sections 7.9 and 9.1, a married Member may elect to receive the Single
        Life Annuity or to designate someone other than his Spouse as his
        contingent joint annuitant; provided it must





                                    VII-6
<PAGE>   38
        be expected that the Member will receive more than 50% of the present
        value of his Accounts under such annuity.

                 (b)     Single Life Annuity.  If a Member who is not married
        on the benefit payment date elects not to receive a lump sum, the
        Member shall receive his distribution in the form of a Single Life
        Annuity providing him with equal monthly payments for his lifetime.
        The amount of such annuity shall be the maximum amount that may be
        obtained by purchasing an annuity contract with the Member's Accounts
        from an insurance company selected by the Committee.  Subject to
        Section 7.9, the Member may elect to receive the Joint and Survivor
        Annuity.

                 (c)     A Member may elect to receive his distribution in
        annual, semi-annually, quarterly or monthly installments payable in
        substantially equal amounts continuing over a period certain not
        exceeding the Member's (or the Member's and his beneficiary's joint)
        life expectancy(ies) as of the date such payments begin.  At the time
        of the election, the Member must specify the fixed period and the
        frequency of the installments elected.  The installment payments shall
        be provided from an insurance company contract purchased with the
        amount of the Accounts.

7.9     ELECTION TO RECEIVE AN ANNUITY:  The Committee shall furnish certain
general information pertinent to the annuities to each Member at least 30 but
not more than 90 days prior to such Member's benefit payment date.  The
furnished information shall be in accordance with such regulations as the
Secretary of the Treasury may prescribe and shall include a general explanation
of (i) the annuity, (ii) the Member's right to make, and the effect of an
election or revocation of an election to receive the annuity, and (iii) the
rights of the Spouse with respect to the Joint and Survivor Annuity.  The
period of time during which a Member may make the election described in this
Section 7.9 shall be at any time during the 90-day period prior to the Member's
benefit payment date.  Any election may be revoked and subsequent elections may
be made or revoked at any time and any number of times during such election
period.

7.10    PRE-RETIREMENT SURVIVOR ANNUITY:  Except as provided below, if a
married Member who has elected the Joint and Survivor Annuity dies before his
benefit payment date, his Spouse shall receive a Pre-retirement Survivor
Annuity commencing as soon as practicable following the date of the Member's
death; however, the Spouse may direct that the annuity start on any subsequent
date specified by the Spouse which is not later than the date the Member would
have reached age 65.  The amount of the annuity (equal monthly payments for the
Spouse's lifetime) shall be the maximum amount that may be obtained with the
Member's Accounts by purchasing an annuity contract from an insurance company
selected by the Committee.

        A Spouse who is entitled to receive the Pre-retirement Survivor Annuity
may elect to receive a lump sum payment of the Member's Accounts in lieu of the
annuity by furnishing the Committee the proper form at any time prior to the
date such insurance contract is purchased.





                                    VII-7
<PAGE>   39
7.11    ELECTION NOT TO RECEIVE THE PRE-RETIREMENT SURVIVOR ANNUITY:  A Member
who has elected to receive the Joint and Survivor Annuity may elect, by
executing the election form prescribed by the Committee, not to be covered by
the Pre-retirement Survivor Annuity.  Such election must be made during the
election period described below.  Any election may be revoked and subsequent
elections may be made or revoked at any time during such election period.  Any
such election and any revocation of such election must be signed by the
Member's Spouse and acknowledge the effect of such election on the Spouse's
right to benefits and further, the Spouse's signature must be notarized, and
designate a specific beneficiary and the specific form of payment that cannot
be changed without a new spousal consent.

        The Committee shall furnish certain general information pertinent to
this election to each Member within the period beginning on the first day of
the Plan Year in which the Member attains age 32 and ending with the close of
the Plan Year preceding the Plan Year in which the Member attains age 35.  With
respect to an Employee who becomes a Member of the Plan after the date the
general information is required to be furnished, such information shall be
furnished on or about the date that such Member begins participation in the
Plan.  The furnished information shall be written in accordance with such
regulations as the Secretary of Treasury may prescribe and shall contain a
general explanation of (i) the terms and conditions of Pre-retirement Survivor
Annuity (ii) the Member's right to make and the effect of, an election or
revocation of an election to waive the Pre-retirement Survivor Annuity, and
(iii) the rights of the Member's Spouse with respect to the Pre-retirement
Survivor Annuity.  The Member may make or revoke the election described in this
Section 7.11 at any time.

7.12    DIRECT ROLLOVER:  Notwithstanding any provision of the Plan to the
contrary that would otherwise limit a distributee's election under this
Section, a distributee may elect, at the time and in the manner prescribed by
the Committee, to have any portion of an eligible rollover distribution paid
directly to an eligible retirement plan specified by the distributee in a
direct rollover.

        Eligible rollover distribution:  An eligible rollover distribution is
any distribution of all or any portion of the balance to the credit of the
distributee, except that an eligible rollover distribution does not include:
any distribution that is one of a series of substantially equal periodic
payments (not less frequently than annually) made for the life (or life
expectancy) of the distributee or the joint lives (or joint life expectancies)
of the distributee and the distributee's designated beneficiary, or for a
specified period of ten years or more; any distribution to the extent such
distribution is required under section 401(a)(9) of the Code; and the portion
of any distribution that is not includible in gross income (determined without
regard to the exclusion for net unrealized appreciation with respect to
employer securities).

        Eligible retirement plan:  An eligible retirement plan is an individual
retirement account described in section 408(a) of the Code, an individual
retirement annuity described in section 408(b) of the Code, an annuity plan
described in section 403(a) of the Code, or a qualified trust described in
section 401(a) of the Code, that accepts the distributee's eligible rollover
distribution.  However,





                                    VII-8
<PAGE>   40
in the case of an eligible rollover distribution to the surviving spouse, an
eligible retirement plan is an individual retirement account or individual
retirement annuity.

        Distributee:  A distributee includes an Employee or former Employee.
In addition, the employee's or former Employee's surviving spouse and the
Employee's or former Employee's spouse or former spouse who is the alternate
payee under a qualified domestic relations order, as defined in section 414(p)
of the Code, are distributees with regard to the interest of the spouse or
former spouse.

        Direct rollover:  A direct rollover is a payment by the plan to the
eligible retirement plan specified by the distributee.

7.13    30-DAY WAIVER:  If a distribution is one to which sections 401(a)(11)
and 417 of the 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 Committee clearly informs the Member that the
        Member 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 Member, after receiving the notice, affirmatively
        elects a distribution.

7.14    FORFEITURES: Upon a Member's termination of employment with the
Employers and Affiliated Companies the nonvested portion of the Member's
Employer Contributions Account (if any) shall continue to be held in the Trust
until forfeited as of the earlier of the date the Member incurs five
consecutive Breaks in Service or receives a complete distribution of his vested
Accounts.  Forfeited account balances shall be used to reduce future Employer
contributions otherwise due under the Plan.  However, if a Member again becomes
an Employee in the Eligible Class prior to incurring five consecutive Breaks in
Service, his forfeited amount shall be restored, unadjusted for any interim
Trust fund gains or losses, through a special allocation of then existing
forfeitures and/or additional Employer contributions, provided the Member
repays the full amount of such prior distribution to the Plan in cash before
the fifth anniversary of his reemployment date or prior to incurring five
consecutive Breaks of Service, whichever occurs first.

                              AUTHORIZED ABSENCES

8.1     AUTHORIZED ABSENCES:  Employee status and service shall include, and
shall not be interrupted by, the following authorized absences for which the
Employee is not directly or indirectly paid:

                 (a)     Absence due to accident or sickness so long as the
        Member is continued on the employment rolls of the Employer or
        Affiliated Company and remains eligible to work upon his recovery.

                 (b)     Absence due to an authorized absence for a period not
        to exceed two years for such reasons and subject to such conditions as
        may be approved by the board of directors of his Employer for general
        application to all Employees similarly situated, provided that each
        such Member shall immediately, upon expiration of such authorized
        absence, apply for reinstatement in the employment of the employing
        company.

                 (c)     Absences in compliance with the Family Medical Leave
        Act.

                 Notwithstanding any provision of this Plan to the contrary,
contributions, benefits and service credit with respect to qualified military
service will be provided in accordance with Code Section 414(u).

8.2     EFFECT OF AUTHORIZED ABSENCES:  Members on Authorized Absence status
shall be treated as if they were employed by a non-participating Affiliated
Company.

                      BENEFICIARIES IN THE EVENT OF DEATH

9.1     BENEFICIARIES:  Upon the death of a Member, his Vested Accounts shall
be distributed to the beneficiary or beneficiaries designated by him in a
written designation on a Plan form filed with his Employer or, if no such
designation shall have been so filed, to his Spouse or, if none, to his estate.
No such designation of beneficiary shall be effective (whether or not made
prior to marriage) if the Member has a Spouse as of his date of death, unless
such Spouse is designated as the sole beneficiary, or unless such Spouse
consents to the designation of another specified person (and form of payment)
as beneficiary.  The Spouse's consent must be in writing, acknowledge the
effect of the consent on the Spouse's right to benefits under the Plan, and be
witnessed by a Plan representative or a notary public.  The beneficiary
designated by the Member may not be changed without the Spouse's consent,
however, a revocation of a designation of a beneficiary other than the Spouse
may be made by a Member without the consent of the Spouse at any time before
the distribution of the benefit under the Plan.  The Spouse's consent to a
beneficiary designation shall not be required if it is established to the
satisfaction of the Committee that such written consent may not be obtained
because there is no Spouse or the Spouse cannot be located.  Any consent under
this Article IX will be valid only with respect to the Spouse who signs the
consent.  The divorce of a Member shall automatically revoke such former spouse
as his beneficiary under the Plan, except to the extent otherwise provided in a
qualified domestic relations order.

        questions of eligibility and determine the amount, manner and time of
        payment of any benefits hereunder;

                 (h)     To prescribe forms and procedures to be followed by
        Employees applying for membership, Members electing or changing Savings
        Contributions or Salary Deferral Contributions, Members or
        beneficiaries filing applications for benefits, Members applying for
        withdrawals, and other occurrences in the administration of the Plan;

                 (i)     To prepare and distribute, in such manner as the
        Committee determines to be appropriate, information explaining the
        Plan;

                 (j)     To receive from the Company, or Affiliated Companies,

        administration of the Plan;

                 (k)     To furnish the Company or Affiliated Companies, upon
        request, such annual reports with respect to the administration of the
        Plan as are reasonable and appropriate;

                 (l)     To receive, review and keep on file (as it deems

responsibility for administering the Plan and carrying out its provisions;
subject, however, to the provisions of the Plan and the Trust Agreement.





                                     X-2
<PAGE>   45
        Subject to the limitations of the Plan, the Committee, from time to
time, shall establish rules for the administration of the Plan and the
transaction of its business.  As to all matters of administration not reserved
in the Plan to the Board of Directors or the Boards of Directors of the
Employers, the determination of the Committee as to any disputed question shall
be conclusive.  All such rules and decisions of the Committee shall be
uniformly and consistently applied in order that all Members in similar
circumstances shall be treated alike.

        It shall be the duty of the Committee to notify the Trustee in writing
of the termination of service of any Member under the Plan and of the amount of
cash which shall be payable to such Member upon termination of service, and the
date distributions are to commence.  The Committee shall not requisition any
payment from the Trustee except upon certification by the Committee that such
amount is for payment of benefits under the Plan or for the payment of expenses
of administering the Plan.  Any such certification by the Committee shall be
deemed conclusively true insofar as the Trustee is concerned.

        All resolutions or other actions taken by the Committee at the meeting
shall be by vote of the majority of the Committee attending the meeting.

10.4    ACCOUNTS RECORDS:  The Committee shall maintain accounts showing the
fiscal transactions of the Plan and shall keep, or cause the Employers to keep,
in convenient form, such data as may be necessary for valuation of the assets.
The Committee shall prepare annually a report showing in reasonable summary the
assets and liabilities of the Plan and giving a brief account of the operation
of the Plan for the past Plan Year and any further information which the Boards
of Directors of the Employers may require and as the Committee can reasonably
furnish or can obtain from the Trustee.  Such report shall be submitted to the
Boards of Directors of the Employers and shall be filed in the office of the
Secretary of the Committee, where it shall be open to inspection by any Member.
The Committee shall exercise such other authority and responsibility as it
deems appropriate in order to comply with ERISA and governmental regulations
issued thereunder relating to (i) records of Members' service, Account balances
and the percentage of such Account balances which are nonforfeitable under the
Plan; (ii) notifications to Members; and (iii) annual reports to the Internal
Revenue Service.  Unless otherwise required by law, the Committee may authorize
any method of accounting for, or of reporting, information with respect to Plan
assets and Account balances which fairly and accurately presents the fair
market value, determined in accordance with the Plan, of the Plan assets and
Account balances as of such date.

10.5    ALLOCATION OF RESPONSIBILITY AMONG FIDUCIARIES FOR PLAN AND TRUST FUND
ADMINISTRATION:  The fiduciaries of the Plan shall have only those specific
powers, duties, responsibilities and obligations as are specifically given them
under this Plan or the Trust Agreement.  In general, the Companies shall have
the sole responsibility for making the contributions provided under Article IV.
The Board of Directors shall have the sole authority to appoint and remove the
Trustee, members of the Committee and to amend or terminate, in whole or in
part, this Plan or the Trust.  The Committee shall have the sole responsibility
for the administration of this Plan, which responsibility is specifically
described in this Plan and the Trust.  The Committee shall have the sole
responsibility





                                     X-3
<PAGE>   46
for selecting an entity to hold and manage the assets in the Plan and for
selecting a guaranteed investment contract(s) to be acquired by the Trustee.
The Trustee shall have the sole responsibility for the administration of the
Trust Fund and the management of the assets held under the Trust, except when
an Investment Manager has been appointed by the Committee, all as specifically
provided in the Trust.  Each fiduciary shall warrant that any directions given,
information furnished, or action taken by it shall be in accordance with the
provisions of the Plan or the Trust Agreement, as the case may be, authorizing
or providing for such direction, information or action.  Furthermore, each
fiduciary may rely upon any such direction, information or action of another
fiduciary as being proper under this Plan or the Trust, and is not required
under this Plan or the Trust Agreement to inquire into the propriety of any
such direction, information or action.  It is intended under this Plan and the
Trust Agreement that each fiduciary shall be responsible for the proper
exercise of its own powers, duties, responsibilities and obligations under this
Plan and the Trust and shall not be responsible for any act or failure to act
of another fiduciary.  No fiduciary guarantees the Trust Fund in any manner
against investment loss or depreciation in asset value.

10.6    PRESENTING CLAIMS FOR BENEFIT:   Any Member or any beneficiary claiming
under a deceased Member, may submit written application to the Committee for
the payment of any benefit asserted to be due him under the Plan.  Such
application shall set forth the nature of the claim and such other information
as the Committee may reasonably request.  Promptly upon the receipt of any
application required by this Section 10.6, the Committee shall determine
whether or not the Member or beneficiary involved is entitled to a benefit
hereunder and, if so, the amount thereof and shall notify the claimant of its
findings.

        If a claim is wholly or partially denied, the Committee shall so notify
the claimant within 90 days after receipt of the claim by the Committee, unless
special circumstances require an extension of time for processing the claim.
If such an extension of time for processing is required, written notice of the
extension shall be furnished to the claimant prior to the end of the initial
90-day period.  In no event shall such extension exceed a period of 90 days
from the end of such initial period.  The extension notice shall indicate the
special circumstances requiring an extension of time and the date by which the
Committee expects to render its final decision.  Notice of the Committee's
decision to deny a claim in whole or in part shall be set forth in a manner
calculated to be understood by the claimant and shall contain the following:

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

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

                 (c)     a description of any additional material or
        information necessary for the claimant to perfect the claim and an
        explanation of why such material or information is necessary, and

                 (d)     an explanation of the claims review procedure set
        forth in Section 10.7 hereof.





                                     X-4
<PAGE>   47

        If notice of denial is not furnished, and if the claim is not granted
within the period of time set forth above, the claim shall be deemed denied for
purposes of proceeding to the review stage described in Section 10.7.

10.7    CLAIM REVIEW PROCEDURE:  If an application filed by a Member or
beneficiary under Section 10.6 above shall result in a denial by the Committee
of the benefit applied for, either in whole or in part, such applicant shall
have the right, to be exercised by written application filed with the Committee
within 60 days after receipt of notice, of the denial of his application or, if
no such notice has been given, within 60 days after the application is deemed
denied under Section 10.6 to request the review of his application and of his
entitlement to the benefit applied for.  Such request for review may contain
such additional information and comments as the applicant may wish to present.
Within 60 days after receipt of any such request for review, the Committee
shall reconsider the application for the benefit in light of such additional
information and comments as the applicant may have presented, and if the
applicant shall have so requested, shall afford the applicant or his designated
representative a hearing before the Committee.  The Committee shall also permit
the applicant or his designated representative to review pertinent documents in
its possession, including copies of the plan document and information provided
by the Company relating to the applicant's entitlement to such benefit.  The
Committee shall make a final determination with respect to the applicant's
application for review as soon as practicable, and in any event not later than
60 days after receipt of the aforesaid request for review, except that under
special circumstances, such as the necessity for holding a hearing, such 60-day
period may be extended to the extent necessary, but in no event beyond the
expiration of 120 days after receipt by the Committee of such request for
review.  If such an extension of time for review is required because of special
circumstances, written notice of the extension shall be furnished to the
applicant prior to the commencement of the extension.  Notice of such final
determination of the Committee shall be furnished to the applicant, in writing,
in a manner calculated to be understood by him, and shall set forth the
specific reasons for the decision and specific references to the pertinent
provisions of the Plan upon which the decision is based.  If the decision on
review is not furnished within the time period set forth above, the claim shall
be deemed denied on review.

10.8    DISPUTED BENEFIT:  If any dispute shall arise between a Member or other
person claiming under a Member and the Committee after the review of a claim
for benefits, or in the event any dispute shall develop as to the person to
whom the payment of any benefit under the Plan shall be made, the Trustee may
withhold the payment of all or any part of the benefits payable hereunder to
the Member or other person claiming under the Member until such dispute has
been resolved by a court of competent jurisdiction or settled by the parties
involved.

10.9    UNCLAIMED BENEFIT:  If at, after, or during the time when a benefit
hereunder is payable to any Member, beneficiary or other distributee, the
Committee, upon request of the Trustee, or at its own instance, shall mail by
registered or certified mail to such Member, beneficiary or distributee, at his
last known address a written demand for his then address or for satisfactory
evidence of his continued life, or both, and if such Member, beneficiary or
distributee shall fail to furnish the same to the Committee within two years
from the mailing of such demand, then the Committee may, in





                                     X-5
<PAGE>   48
its sole discretion, determine that such Member, beneficiary or other
distributee has forfeited his right to such benefit and may declare such
benefit, or any unpaid portion thereof, terminated as if the death of the
distributee (with no surviving beneficiary) had occurred on the date of the
last payment made thereon, or on the date such Member, beneficiary or
distributee first became entitled to receive benefit payments, whichever is
later; provided, however, that such forfeited benefit shall be reinstated if a
claim for the same is made by the Member, beneficiary or other distributee at
any time thereafter.  Reinstatement shall be made by Company contributions or
forfeitures, if any.

                                     TRUST

11.1    ESTABLISHMENT: A Trust Fund shall be established, operated and
maintained exclusively for the collective investment and reinvestment of moneys
received from Members and Employers, in accordance with the investment
directions of Members, and the Trust Fund shall be under the exclusive
management and control of the Trustee, except when and for the specific
purposes that an Investment Manager has been properly appointed and is acting
pursuant to direction of the Committee.

11.2    EXCLUSIVE INVESTMENTS:  The Trustee shall invest moneys in the Trust
Fund exclusively in the investments funds provided for under the Plan.

11.3    BENEFICIAL INTERESTS:  Each Member shall have a beneficial interest in
the Trust Fund.  No Member shall have priority or preference over any other
Member as to any assets of the Plan.

11.4    SEPARATE ACCOUNTS:  The Committee shall maintain separate accounts for
each Member to reflect each Member's interest in the Trust Fund.  Each Member
shall have an Employer Contribution Account, a Savings Contribution Account, a
Salary Deferral Contribution Account and/or a Rollover Account.

                                  ARTICLE XII
              TERMINATION, AMENDMENT AND MODIFICATION OF THE PLAN

12.1    POWERS RESERVED:  The Corporation, by action of its Board of Directors,
may terminate the Plan in its entirety, or as to any Employer at any time, or
may at any time, or from time to time, amend or modify it, except that no
amendment or modification shall reduce (directly or indirectly) an accrued
benefit, eliminate an optional form of benefit (except as otherwise permitted
by regulations) or adversely change the vesting schedule with respect to any
Employee who is credited with three or more years of service.  In addition the
Committee may amend the Plan, subject to the foregoing limitations, provided
that any amendment by the Committee may not materially increase the
Corporation's obligations under the Plan.  Any such termination, amendment or
modification shall be effective at such date as the Corporation may determine.
An amendment or modification to the Plan may be effective as to all Employers
or as to any one of them, and their respective employees.  An amendment or
modification which increases the duties of the Trustee may be made only with
the consent of the Trustee.  An amendment or modification may affect Members in
the Plan at the time thereof, as well as future Members, but may not diminish
the account of any Member as of the effective date of amendment or modification
unless required by the Internal Revenue Service in order for the plan to
continue to be a qualified plan under Code Section 401.

12.2    EFFECT OF TERMINATION:  Upon any total or partial termination of the
Plan or upon discontinuance of contributions by any Employer, each affected
Member, as to whom the Plan is terminated, or as to whom Employer Contributions
have been discontinued, shall receive a fully vested interest in his Accounts.
Upon a termination of the Plan, distribution shall be made only in accordance
with the modes of distributions provided for under the Plan and subject to
their requirements; provided, however, written consent with respect to accounts
greater than $5,000 shall not be required if the Corporation and the Affiliated
Companies do not maintain any other defined contribution plan.

12.3    MERGER OF PLAN WITH ANOTHER PLAN:  In the event of any merger or
consolidation of the Plan with, or transfer in whole or in part of the assets
and liabilities of the Trust Fund to another trust fund held under any other
plan of deferred compensation maintained or to be established for the benefit
of all or some of the Members of this Plan, the assets of the Trust Fund
attributable to such Members shall be transferred to the other trust fund only
if:

                 (a)     Each Member would (if either this Plan or the other
        plan then terminated) receive a benefit immediately after the merger,
        consolidation or transfer which is equal to or greater than the benefit
        he would have been entitled to receive immediately before the merger,
        consolidation or transfer (if this Plan had then terminated);

                 (b)     Resolutions of the Board of Directors of the Employer
        under this Plan, or of any new or successor employer of the affected
        Members, shall authorize such transfer of assets; and, in the case of
        the new or successor employer of the affected Members, its





                                    XII-1
<PAGE>   51
        resolutions shall include an assumption of liabilities with respect to
        such Member's inclusion in the new employer's Plan; and

                 (c)     Such other plan and trust are qualified under Code
        Sections 401(a) and 501(a).

                                    EXPENSES

13.1    EXPENSES:  Unless paid by the Plan, all costs and expenses incurred in
the administration hereof, including the expenses of the Committee, the fees
and expenses of the Trustee, the fees of counsel, and other administrative
expenses shall be paid by the Plan, unless the Employers voluntarily pay any of
such expenses, in which event they shall be ratably shared by the several
Employers.

13.2    TAXES:  Taxes, if any, on any assets held hereunder by the Trustee, or
upon income therefrom, which are payable by the Trustee, shall be charged
against such assets or income and allocated as the Trustee and the Committee
shall determine.

                           MISCELLANEOUS  PROVISIONS

14.1    TERMS OF EMPLOYMENT:  The adoption and maintenance of the provisions of
this Plan shall not be deemed to constitute a contract between any Employer and
Employee, or to be a consideration for, or an inducement or condition of, the
employment of any person.  Nothing herein contained shall be deemed to give to
any Member the right to be retained in the employ of an Employer or to
interfere with the right of an Employer to discharge a Member at any time, nor
shall it be deemed to give to an Employer the right to require any Member to
remain in its employ, nor shall it interfere with any Member's right to
terminate his employment at any time.

14.2    CONTROLLING LAWS; GOVERNMENT REGULATIONS:  Except to the extent
preempted by applicable federal law, this Plan shall be construed, regulated
and administered under the laws of the State of Texas.  The Plan, and the
purchase and sale of securities pursuant thereto, and the obligations of the
Trustee thereunder to purchase or sell securities, shall be subject to all
applicable laws, rules and regulations, and to such approvals by any
governmental agencies or national securities exchanges as may be required.

14.3    INVALIDITY OF PARTICULAR PROVISIONS:  In the event any provision of
this Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining provisions of this Plan but shall be
fully severable, and this Plan shall be construed and enforced as if said
illegal or invalid provisions had never been inserted therein.

14.4    NON-ALIENABILITY OF RIGHTS OF MEMBERS:  No interest, right or claim in
or to any part of the Trust 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 shall not recognize any attempt to assign, transfer, sell, mortgage,
pledge, hypothecate, commute or anticipate the same.  The foregoing shall also
apply to the creation, assignment, or recognition of a right to any benefit
payable with respect to a Member pursuant to a domestic relations order, unless
such order is determined to be a qualified domestic relations order ("QDRO"),
as defined in Code Section 414(p); provided, however, to the extent directed or
authorized by a QDRO, the Plan may make a distribution prior to a Member's
"earliest retirement age," as defined in Section 414(p) of the Code.

14.5    PAYMENTS IN SATISFACTION OF CLAIMS OF MEMBERS:  Any payment or
distribution to any Member or his legal representative or any beneficiary in
accordance with the provisions of this Plan shall be in full satisfaction of
all claims under the Plan against the Trust Fund, the Trustee and the Employer.
The Trustee may require that any distributee execute and deliver to the Trustee
a receipt and a full and complete release as a condition precedent to any
payment or distribution under the Plan.

14.6    PAYMENTS DUE MINORS AND INCOMPETENTS:  If the Committee determines that
any person to whom a payment is due hereunder is a minor or is incompetent by
reason of physical or mental





                                    XIV-1
<PAGE>   54
disability, the Committee shall have power to cause the payment becoming due
such person to be made to another for the benefit of such minor or incompetent,
without the Committee or the Trustee being responsible to see to the
application of such payment.  Payment made pursuant to such power shall operate
as a complete discharge of the Committee, the Trustee and the Employer.

14.7    ACCEPTANCE OF TERMS AND CONDITIONS OF PLAN BY MEMBERS:  Each Member, by
making application to become a Member under this Plan, or by the execution of
any form authorized under the terms of this Plan for himself, his heirs,
executors, administrators, legal representatives and assigns, approves and
agrees to be bound by the provisions of this Plan and the Trust and any
subsequent amendments thereto, and all actions of the Committee and the Trustee
hereunder.

14.8    IMPOSSIBILITY OF DIVERSION OF TRUST FUND:  Notwithstanding any
provision herein to the contrary, no part of the corpus or the income of the
Trust Fund shall ever be used for, or diverted to, purposes other than for the
exclusive benefit of the Members or their beneficiaries or for the payment of
expenses of the Plan.  Except as otherwise provided in Section 15.9, no part of
the Trust Fund shall ever directly or indirectly revert to the Employer.

14.9    REFUNDS TO EMPLOYER:  Once contributions are made to the Plan by the
Employer on behalf of the Members, they are not refundable to the Employer
unless a contribution:

                 (a)     was made by mistake of fact; or

                 (b)     was made conditioned upon the contribution being
        allowed as a deduction and such deduction was disallowed.

Any contribution made by the Employer during any Plan Year in excess of the
amount deductible or any contribution attributable to a good faith mistake of
fact shall be refunded to the Employer.  The amount which may be returned to
the Employer is the excess of the amount contributed over the amount that would
have been contributed had there not occurred a mistake of fact or the excess of
the amount contributed over the amount deductible, as applicable.  A
contribution made by reason of a mistake of fact may be refunded only within
one year following the date of payment.  Any contribution to be refunded
because it was not deductible under Code Section 404 may be refunded only
within one year following the date the deduction was disallowed.  Earnings
attributable to any such excess contribution may not be withdrawn, but losses
attributable thereto must reduce the amount to be returned.  In no event may a
refund be due which would cause the Account balance of any Member to be reduced
to less than the Member's Account balance would have been had the mistaken
amount, or the amount determined to be nondeductible, not been contributed.

15.1    ELIGIBILITY AND ADOPTION:  Any Affiliated Company approved by the Board
of Directors may participate as an Employer in the Plan upon the following
conditions:

                 (a)     Such Affiliated Company shall make, execute and
        deliver such instruments and take such other action as the Corporation
        or the Committee shall deem necessary or desirable.

                 (b)     Such Affiliated Company shall appoint the Corporation
        as its agent to act for it in all transactions in which the Corporation
        believes such agency will facilitate the administration of the Plan.

                         TOP-HEAVY  PLAN  REQUIREMENTS

16.1    GENERAL RULE:  For any Plan Year for which this Plan is a Top-Heavy
Plan, as defined in Section 16.6, and despite any other provisions of this Plan
to the contrary, this Plan shall be subject to the provisions of this Article
XVI.

16.2    VESTING PROVISIONS:  Each Member who has completed an Hour of Service
after the Plan becomes top-heavy shall be immediately 100% vested in his
account under this Plan.

16.3    MINIMUM CONTRIBUTION PROVISIONS:  Each Member who (i) is a Non-Key
Employee, and (ii) is employed on the last day of the Plan Year (regardless of
whether the Member has completed 1,000 Hours of Service during the Plan Year,
made a required contribution that year, or his level of compensation), will be
entitled to have contributions and forfeitures allocated to his account of not
less than 3% (the "Minimum Contribution Percentage") of the Member's
Compensation.  This Minimum Contribution Percentage will be reduced for any
Plan Year to the percentage at which contributions (including forfeitures) are
made or are required to be made under the Plan for the Plan Year for the Key
Employee for whom such percentage is the highest for such Plan Year.  If the
Member also participates in a defined benefit plan of the Employer that is top
heavy, he shall receive the minimum under such defined benefit plan rather than
this Plan.

        Contributions considered under the first paragraph of this Section 16.3
will include Employer contributions under this Plan and under all other defined
contribution plans required to be included in an Aggregation Group, but will
not include Employer Contributions under any plan required to be included in
such Aggregation Group if the plan enables a defined benefit plan required to
be included in such group to meet the requirements of the Code prohibiting
discrimination as to contributions in favor of employees who are officers,
shareholders, or the highly compensated or prescribing the minimum
participation standards.  If the highest rate allocated to a Key Employee for a
year in which the plan is top-heavy is less than 3%, amounts contributed as a
result of a salary reduction agreement must be included in determining
contributions made on behalf of Key Employees.

        Contributions considered under this Section will not include any
contributions under the Social Security Act or any other federal or state law.

16.4    LIMITATION ON CONTRIBUTIONS:  In the event that the Company, other
Employer or an Affiliated Company (hereinafter in this Article collectively
referred to as a "Considered Company") also maintains a defined benefit plan
providing benefits on behalf of Members in this Plan, one of the two following
provisions will apply:

                 (a)     If, for the Plan Year, this would not be a Top-Heavy
        Plan if "90%" were substituted for "60%", in Section 16.6, then the
        percentage of 3% used in Section 16.3 is changed to 4%.





                                    XVI-1

                 (b)     If, for the Plan Year, this Plan would continue to be
        a Top-Heavy Plan if "90%" were substituted for "60%", in Section 16.6,
        then the denominator of both the defined contribution plan fraction and
        the defined benefit plan fraction will be calculated as set forth in
        Section 4.11 for the limitation year ending in such Plan Year by
        substituting "1.0" for "1.25" in each place such figure appears.  This
        subsection (b) will not apply for such Plan Year with respect to any
        individual for whom there are no (i) Employer Contributions,
        forfeitures or voluntary nondeductible contributions allocated to such
        individual, or (ii) accruals earned under the defined benefit plan.

16.5    UNIFORM ACCRUAL:  For Plan Years beginning after December 31, 1986, a
uniform benefit accrual rate must be used in determining whether a plan is
top-heavy or super top-heavy.  If all of the employer's plans accrue benefits
at the same rate, that accrual rate is to be used to determine if its plans are
top-heavy or super top-heavy.  If no single accrual rate is used uniformly by
all of the Employer's plans, the slowest accrual rate permitted under the
fractional method must be used to determine the accrued benefit for Non-Key
Employees.

16.6    DETERMINATION OF TOP-HEAVY STATUS:  The Plan will be a Top-Heavy Plan
for any Plan Year if, as of the Determination Date, the aggregate of the
accounts under the Plan for Members (including former Members) who are Key
Employees exceeds 60% of the aggregate of the accounts of all Members,
excluding former Key Employees, or if this Plan is required to be in an
Aggregation Group in any such Plan Year in which such Group is a Top-Heavy
Group.  In determining Top-Heavy status, if an individual has not performed any
services for any Affiliated Company at any time during the five-year period
ending on the Determination Date, any accrued benefit for such individual and
the aggregate accounts of such individual shall not be taken into account.

        In determining whether this Plan constitutes a Top-Heavy Plan, the
Committee (or its agent) will make the following adjustments:

                 (a)     When more than one plan is aggregated, the Committee
        shall determine separately for each plan as of each plan's
        Determination Date the present value of the accrued benefits (for this
        purpose using the actuarial assumptions set forth in the applicable
        plan) or account balance.  The results shall then be aggregated by
        adding the results of each plan as of the Determination Dates for such
        plans that fall within the same calendar year.

                 (b)     In determining the present value of the cumulative
        accrued benefit or the amount of the account of any Employee, such
        present value or account will include the amount in dollar value of the
        aggregate distributions made to such employee under the applicable plan
        during the five-year period ending on the Determination Date unless
        reflected in the value of the accrued benefit or account balance as of
        the most recent Valuation Date.  The amounts will include distributions
        to employees representing the entire amount credited to their accounts
        under the applicable plan.

                 (c)     Further, in making such determination, such present
        value or such account shall include any rollover contribution (or
        similar transfer), as follows:

                         (1)      If the rollover contribution (or similar
                 transfer) is initiated by the Employee and made to or from a
                 plan maintained by another Affiliated Company, the plan
                 providing the distribution shall include such distribution in
                 the present value or such account; the plan accepting the
                 distribution shall not include such distribution in the
                 present value or such account unless the plan accepted it
                 before December 31, 1983.

                         (2)      If the rollover contribution (or similar
                 transfer) is not initiated by the employee or made from a plan
                 maintained by another Affiliated Company, the plan accepting
                 the distribution shall include such distribution in the
                 present value or such account, whether the plan accepted the
                 distribution before or after December 31, 1983; the  plan
                 making the distribution shall not include the distribution in
                 the present value or such account.

                 (d)     In any case where an individual is a Non-Key Employee
        with respect to an applicable plan, but was a Key Employee with respect
        to such plan for any prior Plan Year, any accrued benefit and any
        account of such Employee will be altogether disregarded.  For this
        purpose, to the extent that a Key Employee is deemed to be a Key
        Employee if he or she met the definition of Key Employee within any of
        the four (4) preceding Plan Years, this provision will apply following
        the end of such period of time.

        IN WITNESS WHEREOF, the Corporation has caused these presents to be
executed by its authorized individual, in a number of copies, all of which
shall constitute but one and the same instrument, which may be evidenced by any
such executed copy hereof, this June __, 1998, effective for all purposes as
provided above.

                                SAVINGS PLAN FOR
                        TACOMA BARGAINING UNIT EMPLOYEES

         Pioneer Chlor Alkali Company, Inc. hereby amends, renames, and restates
the Pioneer Tacoma Bargaining Unit 401(k) Plan effective as of July 1, 1998,
unless provided otherwise herein. The terms and provisions of the Plan as so
amended are as follows:

                                  INTRODUCTION

         The purposes of this Plan are to provide benefits for eligible
Employees through an Employer profit sharing contribution and to promote and
encourage Employees to provide additional security and income for their
retirement through a systematic matching savings program. However, the
establishment of this Plan shall not be considered as giving any Employee or any
other person any legal or equitable right as against any Employer, the Committee
or the Trustee, or in the assets of the Plan, except and to the extent that such
right is specifically provided for in this Plan.

         This Plan has been adopted for the exclusive benefit of the Members and
their beneficiaries. So far as possible, this Plan shall be interpreted in a
manner consistent with this intent and with the intention of the Corporation
that this Plan shall satisfy those provisions of ERISA and the Code relating to
qualified employee profit sharing plans with a Code Section 401(k) feature.

         The Plan is hereby amended and completely restated as set forth herein
and all rights and benefits under the Plan shall hereafter be determined under
the terms and provisions hereof. However, the amendment and restatement of the
Plan hereby shall not operate or be construed to deprive any Member of any
protected benefit, within the meaning of Code Section 411(d)(6) and the
regulations thereunder, he may have had under the Plan as in effect immediately
prior to this amendment.

                                   DEFINITIONS

         The following words and phrases as used herein shall have the following
meanings unless a different meaning is plainly required by the context:

1.1      ACCOUNT OR ACCOUNTS: The Employer Contribution Account, the Savings
Contribution Account, the Salary Deferral Contribution Account and/or the
Rollover Account of a Member.

1.2      ACTUAL DEFERRAL PERCENTAGE: The Actual Deferral Percentage, as defined
in Section 4.6.

1.3      AFFILIATED COMPANY: Any corporation which is a member of a controlled 
group of corporations (within the meaning of the Code Section 414(b)) with the
Corporation; any trade or business (whether or not incorporated) which is under
common control (as defined in Code Section 414(c)) with the Corporation; any
organization (whether or not incorporated) which is a member of an affiliated
service group (as defined in Code Section 414(m)) which includes the
Corporation; and any other entity required to be aggregated with the Corporation
pursuant to Regulations under Code Section 414(o). For purposes of applying the
limitations of Code Section 415, an Affiliated Company shall be determined in
accordance with Code Section 415(h).

1.4      AGGREGATION GROUP: For purposes of Article XVI, the group of plans, if
any, that includes both the group of plans required to be aggregated and the
group of plans permitted to be aggregated. The group of plans required to be
aggregated (the "required aggregation group") includes:

                  (a) Each plan of an Affiliated Company in which a Key Employee
         is a participant, including collectively bargained plans, and

                  (b) Each other plan, including collectively bargained plans,
         of an Affiliated Company which enables a plan in which a Key Employee
         is a participant to meet the requirements of the Code, as amended,
         prohibiting discrimination as to contributions or benefits in favor of
         employees who are officers, shareholders, or the highly compensated or
         prescribing minimum participation standards.

         The group of plans that are permitted to be aggregated (the "permissive
aggregation group") includes the required aggregation group plus one or more
plans of an Affiliated Company that is not part of the required aggregation
group, and that the Affiliated Company certifies as a plan within the permissive
aggregation group. Such plan or plans may be added to the permissive aggregation
group only if, after the addition, the aggregation group as a whole continues
not to discriminate as to contributions or benefits in favor of officers,
shareholders, or the highly compensated, and to meet the minimum participation
standards under the Code.

415(1), which is part of a defined benefit plan maintained by the Employer, are
treated as Annual Additions. Also, amounts derived from contributions which are
attributable to post-retirement medical benefits allocated to the separate

benefits attributable to Employee contributions and rollover contributions.

1.7      APPLICABLE COMPENSATION: For purposes of Code Section 415, Applicable
Compensation means (i) a Member'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 and also without regard to salary deferral
elections pursuant to Code Sections 125 or 401(k)) for personal services
actually rendered in the course of employment with the Employer or Affiliated
Company maintaining the Plan to the extent that the amounts are includable in
gross income (including, but not limited to, commissions paid salesmen,
compensation for services on the basis of the percentage of profits, commissions
on insurance premiums, tips, bonuses, fringe benefits, reimbursements and
expense allowances), (ii) amounts described in Code Sections 104(a)(3), 105(a)
and 105(h), but only to the extent that these amounts are includable in the

or Affiliated Company for moving expenses incurred by the Employee, but only to
the extent that these amounts are excludable from gross income of the Employee,
(iv) the value of a nonqualified stock option granted to an Employee, but only
to the extent such value is included in the gross income of the employee for the
taxable year in which granted, and (v) the amount included in the gross income

the following:

                  (a) Contributions made by the Employer or Affiliated Company
         to a plan of a deferred compensation to the extent that, before the
         application of the Code Section 415 limitations to that plan, the
         contributions are not includable in the gross income of the Employee
         for the taxable year in which contributed. In addition, Employer
         contributions made on behalf of an Employee to a simplified employee
         pension described in Code Section 408(k) are not considered as
         compensation for the taxable year in which contributed to the extent
         such contributions are deductible by the Employee under Code Section
         219(b)(7). Additionally, any distributions from a plan of deferred
         compensation are not considered as compensation for Code Section 415
         purposes, regardless of whether such amounts are includable in the
         gross income of the Employee when distributed. However, any amounts
         received by an Employee pursuant to an unfunded non-qualified plan may
         be considered as compensation for Code Section 415 purposes in the year
         such amounts are includable in the gross income of the Employee.

         premiums are not includable in the gross income of the Employee), or
         contributions made by an Employer or Affiliated Company (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

by reason of the birth of a child of the Employee, (3) by reason of the
placement of a child in connection with the adoption of the child by the
Employee, or (4) for purposes of caring for the child during the period
immediately following the birth or placement for adoption. During the period of
such absence, the Employee shall be treated as having completed (1) the number
of Hours of Service that normally would have been credited but for the absence,
or (2) if the normal Hours of Service worked are unknown, eight Hours of Service
for each normal workday during the absence. The total number of Hours of Service
required to be treated as completed for any such period of absence shall not
exceed 501 hours for those Hours of Service shall be credited only (1) in the

         hourly rate in effect for such Member at the beginning of the Plan
         Year, or as adjusted during the Plan Year as a result of a negotiated
         agreement between the Member's collective bargaining unit and his
         Employer (subject to the exclusions listed below), multiplied by the
         number of such Member's regularly scheduled work hours in a pay period;
         and

                  (b) for a Member compensated on a Twelve Hour Shift Basis, the
         amount of Compensation for each pay period shall be the Member's annual
         base salary of record (including Guaranteed Overtime) divided by the
         number of pay periods applicable to the Member during the Plan Year.
         For this purpose, the term "Twelve Hour Shift Basis" means any
         arrangement whereby Members work twelve hour daily shifts which may
         result in alternating work weeks of more and less than forty hours per
         week. Additionally, the term "Guaranteed Overtime" means compensation

Employee performing services for the Corporation or an Affiliated Company. It

1.25     HIGHLY COMPENSATED EMPLOYEE: Any Employee or former Employee who is a

Employee or former Employee is considered a Highly Compensated Employee if
during the Plan Year or the preceding Plan Year such Employee or former
Employee:

                  (a) was at any time a "5% owner." "5% owner" means any person
         who owns (or is considered as owning within the meaning of Code Section
         318) more than 5% of the outstanding stock of the Employer or stock
         possessing more than 5% of the total combined voting power of all stock
         of the Employer or, in the case of an unincorporated business, any
         person who owns more than 5% of the capital or profits interest in the
         Employer. In determining percentage ownership hereunder, Affiliated
         Companies that would otherwise be aggregated under Code Section 414(b),

                  (c) if elected by the Corporation for such preceding year, was
         in the top 20% of the Employees when ranked on the basis of Applicable
         Compensation paid during the previous year.

For purposes of determining whether an Employee is a Highly Compensated Employee
for the Plan Year beginning in 1997, the above definition shall be treated as
having been in effect for the Plan Year beginning in 1996.

1.26     HOUR OF SERVICE: Each hour for which an Employee is paid, or entitled 
to payment, for the performance of duties for the Employer or an Affiliated
Company during the applicable computation period. An Hour of Service is each
hour for which an Employee is paid, or entitled to payment by the Employer or an
Affiliated Company on account of a period of time during which no duties are
performed, due to vacation, holiday, illness, incapacity (including disability),
layoff, jury duty, military duty or leave of absence. No more than 501 hours
shall be credited with respect to any single continuous period during which the
Employee performs no duties (whether or not such period occurs in a single
computation period). An hour for which an Employee is directly or indirectly
paid, or entitled to payment, on account of a period during which no duties are
performed is not required to be credited to the Employee if such payment is made
or due under a plan maintained solely for the purpose of complying with
applicable workmen's compensation, or unemployment compensation or disability
insurance laws; and Hours of Service are not required to be credited for a
payment which solely reimburses an Employee for medically related expenses
incurred by the Employee. For purposes of this section, a payment shall be
deemed to be made by or due from an Employer regardless of whether such payment
is made by or due from the Employer directly or indirectly, through, among
others, a trust fund or insurer or other entity to which the Employer
contributes or pays premiums and regardless of whether contributions made or due
to the trust fund, insurer or other entity are for the benefit of particular
employees or on behalf of a group of employees in the aggregate. An Hour of
Service is also 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 in two periods. Crediting of Hours of Service for
back pay awarded or agreed to shall be with respect to the periods within which
such service was performed. For purposes of determining whether a Break in
Service has occurred, an Employee shall be deemed to have completed Hours of
Service for periods of absence from work (1) by reason of the pregnancy of the
Employee, (2) by reason of the birth of a child of the Employee, (3) by reason
of the placement of a child in connection with the adoption of the child by the
Employee, or (4) for purposes of caring for the child during the period
immediately following the birth or placement for adoption. During the period of
such absence, the Employee shall be treated as having completed (1) the number
of Hours of Service that normally would have been credited but for the absence,
or (2) if the normal Hours of Service worked are unknown, eight Hours of Service
for each normal workday during the absence. The total number of Hours of Service
required to be treated as having been completed for any such period of absence
shall not exceed 501 hours. Further, such Hours of Service shall be credited
only (1) in the year which the absence begins for one of the permitted reasons,
if the crediting is necessary to prevent a Break in Service in that year, or (2)
in the following year. Hours of Service shall be credited to computation periods
in accordance with the provisions 

                                       I-6

<PAGE>   14



of Department of Labor Regulation Section 2530.200b. Instead of counting and
crediting actual hours worked, for purposes of determining the number of Hours
of Service to be credited to an Employee, an Employee may be credited with 190
Hours of Service for each calendar month during which he has earned one Hour of
Service. For purposes of determining the number of Hours of Service to be
credited for reasons other than the performance of duties and for purposes of
determining to which computation period Hours of Service earned under any
provision of this Plan are to be credited, the provisions of Department of Labor
Regulation Section 2520.200(b)-2(b) and (c) are hereby incorporated by reference
as if fully set forth herein.

3(38) of ERISA and appointed by the Committee.

was an officer of the Employer if such individual's annual compensation exceeds

Code as applicable to any Plan Year during the determination period, an owner
(or any Employee considered an owner under Code Section 318) of one of the ten
largest interests in an Affiliated Company (provided such interest is greater
than .5%) if such individual's compensation exceeds 100% of such dollar
limitation amount, a 5% owner of an Affiliated Company, or a 1% owner of an
Affiliated Company who has an annual compensation of more than $160,000 (as
adjusted). The determination period is the Plan Year containing the
Determination Date and the four preceding Plan Years. The determination of who
is a Key Employee will be made in accordance with Section 416(i)(1) of the Code
and the regulations thereunder.

1.29     LEASED EMPLOYEE: Any person who (1) is not a common-law employee of the
Employer and (2) pursuant to an agreement between an Employer and any other
person, has performed services for the Employer (or for the Employer and related
persons determined in accordance with Section 414(n)(6) of the Code) on a
substantially full time basis for a period of at least one year, and such
services are performed under the primary direction or control of the Employer.

1.30     MAXIMUM PERMISSIBLE AMOUNT:  For a Plan Year, the Maximum Permissible 
Amount with respect to any Employee shall be the lesser of:

                  (a) $30,000 (as increased in accordance with Code Section
         415(d) to reflect cost-of-living adjustments). No adjustment will be
         made until the $30,000 limit is 25% of the defined benefit limit. The
         two limits will then rise in tandem, with the defined contribution
         limit set at 1/4 of the defined benefit limit. Such adjustments to the
         limits will be based on cost-of-living adjustments in the CPI, or

                  (b) 25% of the Employee's Applicable Compensation for the Plan
         Year.

not vested in his Employer Contribution Account terminates service and incurs
five consecutive Breaks in Service, his Years of Service credited prior to such
Breaks in Service shall be forfeited.

         The masculine gender, wherever used herein, shall include the feminine
gender, and the singular may include the plural, unless the context plainly
indicates to the contrary.

                               PROFIT SHARING PLAN

2.1      PROFITS: This Plan is intended to be a profit sharing plan and all 
Salary Deferral Contributions and Employer Contributions shall be made out of
the Employers' current or accumulated earnings and profits as computed in
accordance with generally accepted accounting principles; however, the Board of
Directors may authorize contributions in the absence of such earnings and
profits in its sole discretion as provided by Code Section 401(a)(27), provided
the Plan continues to qualify as a profit sharing plan.

                                   ELIGIBILITY

3.1      EMPLOYEES ELIGIBLE: Only Employees who are in the Eligible Class shall 
be eligible to actively participate in the Plan, and each such Employee shall be
eligible to make Savings Contributions and/or Salary Deferral Contributions to
the Plan beginning on the first day of the month coincident with or next
following the date on which he first completes an Hour of Service; provided,
however, (1) former Employees who are in the Eligible Class upon the date of
their rehire shall be eligible to participate immediately and (2) Employees who
are in the Eligible Class shall be eligible to make qualifying rollover
contributions to the Plan at any time. The date an Employee in the Eligible
Class is first eligible to contribute to the Plan (other than a rollover
contribution) and the first day of each month thereafter that he remains
eligible to join the Plan is the "entry date."

3.2     SAVINGS CONTRIBUTION OR SALARY DEFERRAL CONTRIBUTION AUTHORIZATION 
REQUIRED: An Employee in the Eligible Class may become a Member of the Plan on
any future entry date by authorizing a Savings Contribution and/or a Salary
Deferral Contribution and directing the investment thereof in the manner
hereinafter provided.

3.3      CONTRIBUTIONS VOLUNTARY: Contributions to the Plan by an Employee are 
entirely voluntary.

3.4      TRANSFERS OF EMPLOYMENT: Transfers of employment between two or more
Employers shall not affect a Employee's membership in the Plan, except as
provided in this Section 3.4. Any transfer of a Member to employment with a
non-participating Affiliated Company or to an employment classification that is
not in the Eligible Class shall not constitute a termination of service. Each
such transferred Member shall remain a Member of the Plan and shall retain the
rights and benefits accrued under the Plan prior to the date of such transfer
until his subsequent retirement, termination of service or total withdrawal.
However, each such transferred Member shall not be eligible to make additional
Savings Contributions or Salary Deferral Contributions while he is employed by a
non-participating Affiliated Company or while he is not employed in the Eligible
Class.

                            CONTRIBUTIONS AND VESTING

4.1      SAVINGS CONTRIBUTIONS: An Employee in the Eligible Class may authorize 
a Savings Contribution, to be effected by payroll deductions, in whole
percentages of not less than 1% and not more than 15% of his Compensation for
such payroll period, subject to Section 4.2.

4.2      SALARY DEFERRAL CONTRIBUTIONS: Subject to Section 4.8, an Employee in
the Eligible Class may elect a Salary Deferral Contribution rate (in whole
percentages) of not less than 1% and not more than 15% of his Compensation for
any payroll period, to be effected by payroll reductions. Each such election of
a Salary Deferral Contribution rate shall be made in writing on a salary
reduction election form provided by the Committee at least ten days prior to the
effective date of such election (if not made as of the date service commences),
shall be subject to reduction as provided in Section 4.8, and shall be subject
to such other terms and conditions as the Committee may determine. The sum of an
Employee's Salary Deferral Contribution rate and Savings Contribution rate may
not exceed 15% and, to the extent necessary, a Member's Savings Contributions
shall be reduced first.

                  (a) A Member's Salary Deferral Contribution made pursuant to
         this Section shall not exceed $10,000 for the taxable year of the
         Member. This dollar limitation shall be adjusted annually as provided
         in Code Section 415(d) pursuant to Regulations. The adjusted limitation
         shall be effective as of January 1 of each calendar year.

                  (b) In the event that the dollar limitation provided for in
         Section 4.2(a) is exceeded, the Committee shall direct the Trustee to
         either (1) distribute such excess amount, and any income (or loss)
         allocable to such amount (as provided in (d) below), to the Member not
         later than the first April 15 following the close of the Member's
         taxable year or (2) to recharacterize such excess amount, and any
         income or (loss) allocable to such amount, as a Savings Contributions
         made by the Member, subject to the further provisions of the Plan
         applicable to Savings Contributions.

                  (c) In the event that a Member is also a participant in (1)
         another qualified cash or deferred arrangement (as defined in Code
         Section 401(k)), (2) a simplified employee pension (as defined in Code
         Section 408(k)), or (3) a salary reduction arrangement (within the
         meaning of Code Section 3121(a)(5)(D)) and the elective deferrals, as
         defined in Code Section 402(g)(3), made under such other arrangement(s)
         and this Plan cumulatively exceed $10,000 (or such amount adjusted
         annually as provided in Code Section 415(d) pursuant to Regulations)
         for such Member's taxable year, the Member may, not later than March 1
         following the close of his taxable year, notify the Committee in
         writing of such excess and request that his Salary Deferral
         Contribution under this Plan be reduced by an amount specified by the
         Member. Such amount shall then be distributed in the same manner as
         provided in Section 4.2(b).


                                      IV-1

<PAGE>   20




                  (d) The income (or loss) allocable to returnable contributions
         shall equal the sum of the allocable gain or loss for the Plan Year and
         the allocable gain or loss for the period between the end of the Plan
         Year and the date of distribution. Income includes all earnings and
         appreciation, including such items as interest, dividends, rent,
         royalties, gains from the sale of property, appreciation in the value
         of stocks, bonds, annuity and life insurance contracts, and other
         property, without regard to whether such appreciation has been
         realized.

                           (1) The income (or loss) allocable to returnable
                  contributions for the Plan Year is determined by multiplying
                  the income (or loss) for the Plan Year allocable to employee
                  contributions, matching contributions, and amounts treated as
                  matching contributions (whichever is applicable) by a
                  fraction. The numerator of the fraction is the amount of
                  returnable contributions made on behalf of the employee for
                  the Plan Year. The denominator of the fraction is the total
                  account balance of the employee attributable to employee
                  contributions, matching contributions and amounts treated as
                  matching contributions as of the end of the Plan Year, reduced
                  by the gain allocable to such total amount for the Plan Year
                  and increased by the loss allocable to such total amount for
                  the Plan Year.

                           (2) The allocable income or loss for the period
                  between the end of the Plan Year and the distribution date is
                  equal to 10 percent of the income or loss allocable to
                  returnable contributions for the Plan Year (as calculated
                  under subparagraph (1) above) multiplied by the number of
                  calendar months that have elapsed since the end of the Plan
                  Year. For purposes of determining the number of calendar
                  months that have elapsed, a distribution occurring on or
                  before the fifteenth day of the month will be treated as
                  having been made on the last day of the preceding month, and a
                  distribution occurring after such fifteenth day will be
                  treated as having been made on the first day of the next
                  month.

4.3      MATCHING EMPLOYER CONTRIBUTIONS: Subject to the other provisions of the
Plan, with respect to each payroll period the Employers shall contribute, with
respect to each Member who made Savings Contributions and/or Salary Deferral
Contributions for such pay period, an amount equal to 50% of the sum of the
Member's Savings Contributions and Salary Deferral Contributions for that
payroll period, but only to the extent the sum of such contributions does not
exceed 6% of the Member's Compensation for the applicable payroll period;
provided that, if a Member has made both Savings Contributions and Salary
Deferral Contributions, the Employer Contributions shall be deemed to have been
made first with respect to the Salary Deferral Contributions.

4.4      CHANGE IN CONTRIBUTION RATE: The Savings Contribution and/or Salary 
Deferral Contribution rate elected by a Member may be changed by a Member, upon
advance notice, as of the first day of any calendar quarter following proper
notice, but any such change shall not be retroactive.


                                      IV-2

<PAGE>   21




4.5      VOLUNTARY SUSPENSION OF CONTRIBUTIONS: A Member who has elected to
contribute and/or defer a portion of his Compensation as a Savings Contribution
and/or Salary Deferral Contribution under the Plan may suspend any further
contributions and/or deferrals as of the end of any payroll period if, and only
if prior to the end of such payroll period, he gives notice to his Employer, in
such form and manner as the Committee may prescribe, of his election to effect
such suspension. Such suspension shall remain in effect until the Member again
properly elects to make contributions to the Plan.

4.6      ACTUAL DEFERRAL PERCENTAGE: For the purposes of this Section, "Actual
Deferral Percentage" means, with respect to the Highly Compensated Employee
group and Non-Highly Compensated Employee group for a Plan Year, the average of
the ratios, calculated separately for each Member in such group, of the amount
of Salary Deferral Contributions allocated to each Member's Salary Deferral
Contribution Account (unreduced by distributions made pursuant to Sections
4.2(b) and 4.2(d)) for such Plan Year, to such Member's Total Compensation for
such Plan Year.

4.7      ACTUAL DEFERRAL PERCENTAGE TEST:

                  (a) Maximum Annual Allocation: For each Plan Year, the annual
         allocation derived from Salary Deferral Contributions to a Member's
         Salary Deferral Contribution Account shall satisfy one of the following
         tests:

                           (1) The "Actual Deferral Percentage" for the Highly
                  Compensated Employee group shall not be more than the "Actual
                  Deferral Percentage" of the Non-Highly Compensated Employee
                  group multiplied by 1.25, or

                           (2) The excess of the "Actual Deferral Percentage"
                  for the Highly Compensated Employee group over the "Actual
                  Deferral Percentage" for the Non-Highly Compensated Employee
                  group shall not be more than two percentage points.
                  Additionally, the "Actual Deferral Percentage" for the Highly
                  Compensated Employee group shall not exceed the "Actual
                  Deferral Percentage" for the Non-Highly Compensated Employee
                  group multiplied by two. This alternative limitation test
                  cannot be used to satisfy the Actual Deferral Percentage test
                  and the Contribution Percentage Test of Section 4.9, except as
                  otherwise provided by applicable regulations.

                  (b) For the purposes of Sections 4.7(a) and 4.8, a Highly
         Compensated Employee and a Non-Highly Compensated Employee shall
         include any Employee eligible to make a deferral election pursuant to
         Section 4.2, whether or not such deferral election was made.

                  (c) For the purposes of this Section, if two or more plans
         which include cash or deferred arrangements are considered one plan for
         the purposes of Code Section 401(a)(4) or 410(b), the cash or deferred
         arrangements included in such plans shall be treated as one
         arrangement.

                                      IV-3

<PAGE>   22




                  (d) For the purposes of this Section, if a Highly Compensated
         Employee is a Member under two or more cash or deferred arrangements of
         the Employer, all such cash or deferred arrangements shall be treated
         as one cash or deferred arrangement for the purpose of determining the
         deferral percentage with respect to such Highly Compensated Employee.

                  (e) Notwithstanding the above, the determination and treatment
         of Employer Salary Deferral Contributions and "Actual Deferral
         Percentage" of any Member shall satisfy such other requirements as may
         be prescribed by the Secretary of the Treasury.

4.8      ADJUSTMENTS AS A RESULT OF ACTUAL DEFERRAL PERCENTAGE TEST: In the 
event that the initial allocations of the Salary Deferral Contributions made
pursuant to the Plan do not satisfy one of the tests set forth in Section
4.7(a), either of the following actions shall be taken:

                  (a) On or before the 15th day of the third month following the
         end of each Plan Year, but in no event later than the close of the
         following Plan Year, the Committee shall direct the Trustee to
         distribute to the Highly Compensated Employee group the aggregate
         amount of excess Salary Deferral Contributions (and any income
         allocable to such contributions as provided in (d) of Section 4.2),
         beginning with the Member(s) having the highest dollar amount of Salary
         Deferral Contributions, reducing such Members' contributions pro rata
         to the next highest dollar amount of Salary Deferral Contributions (and
         continuing with the next highest group and so on) until the aggregate
         excess amount is distributed.

                  (b) Within 30 days after the end of the Plan Year, the
         Employer shall make a contribution on behalf of Non-Highly Compensated
         Employees in an amount sufficient to satisfy one of the tests set forth
         in Section 4.7(a). Such contribution shall be deemed a Salary Deferral
         Contribution and allocated to the Salary Deferral Contribution Account
         of each Non-Highly Compensated Employee in the same proportion that
         each Non-Highly Compensated Employee's Salary Deferral Contribution for
         the year bears to the total Salary Deferral Contributions of all
         Non-Highly Compensated Employees. However, if option (b) is elected,
         then in all events such contributions shall be fully vested when made
         and shall be subject to the same distribution restrictions that apply
         to Salary Deferral Contributions, except that such amounts may not be
         withdrawn prior to the Member's termination of employment.

                  (c) The amount of excess Salary Deferral Contributions to be
         distributed or recharacterized shall be reduced by excess deferrals
         previously distributed for the taxable year ending in the same Plan
         Year and excess deferrals to be distributed for a taxable year will be
         reduced by excess contributions previously distributed or
         recharacterized for the Plan beginning in such taxable year.

4.9      MAXIMUM CONTRIBUTION PERCENTAGE.

                  (a) The "Contribution Percentage" for the Highly Compensated
         Employee group shall not exceed the greater of:

                           (1) 125% of such percentage for the Non-Highly
                  Compensated Employee group; or

                           (2) the lesser of 200% of such percentage for the
                  Non-Highly Compensated Employee group, or such percentage for
                  the Non-Highly Compensated Employee group plus two percentage
                  points or such lesser amount determined pursuant to
                  Regulations to prevent the multiple use of this alternative
                  limitation with respect to any Highly Compensated Employee.

                  (b) For the purposes of this Section and Section 4.10,
         "Contribution Percentage" for a Plan Year means, with respect to the
         Highly Compensated Employee group and Non-Highly Compensated Employee
         group, the average of the ratios (calculated separately for each Member
         in each group) of:

                           (1) the sum of the matching contributions pursuant to
                  Section 4.3 and Employee Savings Contributions pursuant to
                  Section 4.1 contributed under the Plan on behalf of each such
                  Member for such Plan Year; to

                           (2) the Member's Total Compensation for such Plan
                  Year.

                  (c) The "Contribution Percentage" for a Highly Compensated
         Employee shall be determined by including matching contributions
         pursuant to Section 4.3 and Employee Savings Contributions pursuant to
         Section 4.1.

                  (d) For purposes of this Section, if two or more plans of the
         Employer to which matching contributions, Employee contributions, or
         elective deferrals are made are treated as one plan for purposes of
         Code Section 410(b), such plans shall be treated as one plan for
         purposes of this Section 4.9. In addition, if a Highly Compensated
         Employee participates in two or more plans described in Code Section
         401(a) or arrangements described in Code Section 401(k) which are
         maintained by the Employer to which such contributions are made, all
         such contributions shall be aggregated for purposes of this Section
         4.9.

                  (e) For purposes of Section 4.9(a) and 4.10, a Highly
         Compensated Employee and Non-Highly Compensated Employee shall include
         any Employee eligible to have matching contributions pursuant to
         Section 4.3 and Employee Savings Contributions pursuant to Section 4.1
         allocated to his account for the Plan Year.

4.10     ADJUSTMENTS FOR EXCESSIVE CONTRIBUTION PERCENTAGE:

                  (a) In the event that the "Contribution Percentage" for the
         Highly Compensated Employee group exceeds the "Contribution Percentage"
         for the Non-Highly Compensated Employee group pursuant to Section
         4.9(a), the Committee (on or before the 15th day of the third month
         following the end of the Plan Year, but in no event later than the
         close of the following Plan Year) the Committee shall direct the
         Trustee to distribute to the Highly Compensated Employee group the
         amount of "Excess Aggregate Contributions" (and any income allocable to
         such contributions as provided in (d) of Section 4.2), beginning with
         the Member(s) with the highest dollar amount of such contributions,
         reducing such Members' contributions pro rata to the next highest
         dollar amount of contributions (and continuing with the next highest
         group and so on) until the aggregate amount of such excess is
         distributed. However, no forfeiture may be allocated to a Highly
         Compensated Employee whose contributions are reduced pursuant to this
         Section.

                  (b) The determination of the amount of "Excess Aggregate
         Contributions" with respect to any Plan Year shall be made after:

                           (1) first determining the excess contributions
                  pursuant to Section 4.2(a), and

                           (2) then determining the excess annual allocations
                  pursuant to Section 4.7(a).

                  (c) To prevent the multiple use of the alternative methods of
         compliance with the ADP test and the ACP test, the provision of section
         1.401(m)-2 of the regulations are hereby incorporated by reference to
         determine if such multiple use exists. If, after application of such
         test, multiple use exists, the actual contribution percentage shall be
         reduced as provided in section 1.401(m)-2(c) of the regulations for all
         Highly Compensated Employees in the Plan.

                  (d) Notwithstanding anything in the Plan to the contrary, an
         employer matching contribution may be distributed only if such
         contribution is an excess aggregate contribution. It may not be
         distributed merely because it relates to an excess deferral, an excess
         contribution or an excess aggregate contribution that is distributed.
         In such cases, the related matching contribution shall be forfeited
         notwithstanding anything in the Plan to the contrary.

4.11     MAXIMUM ANNUAL ADDITIONS: Notwithstanding anything contained herein to
the contrary, the total Annual Additions made to Accounts of a Member for any
Plan Year shall be subject to the following limitations:


                                      IV-6

<PAGE>   25




         (a)      Single Defined Contribution Plan

                           (1) If an Employer does not maintain any other
                  qualified plan, the amount of Annual Additions which may be
                  allocated under this Plan on a Member's behalf for a Plan Year
                  shall not exceed the lesser of the Maximum Permissible Amount
                  or any other limitation contained in this Plan.

                           (2) Prior to the determination of the Member's actual
                  Applicable Compensation for a Plan Year, the Maximum
                  Permissible Amount may be determined on the basis of the
                  Member's estimated annual Applicable Compensation for such
                  Plan Year. Such estimated annual Applicable Compensation shall
                  be determined on a reasonable basis and shall be uniformly
                  determined for all Members similarly situated.

                           (3) As soon as is administratively feasible after the
                  end of the Plan Year, the Maximum Permissible Amount for such
                  Plan Year shall be determined on the basis of the Member's
                  actual Applicable Compensation for such Plan Year.

                           (4) If there are Excess Annual Additions with respect
                  to a Member for the Limitation Year, such Excess Annual
                  Additions shall be disposed of as follows:

                                    A. There shall first be returned to the
                           Member his unmatched Savings Contributions (and
                           earnings thereon), if any, and then a portion of his
                           matched Savings Contributions (and earnings thereon),
                           to the extent, and only to the extent, such returned
                           Savings Contributions would reduce the Excess Annual
                           Additions.

                                    B. If any of such Excess Annual Additions
                           shall then remain, the Employer Contributions,
                           including both Salary Deferral Contributions defined
                           in Section 4.2 and matching Employer Contributions
                           defined in Section 4.3, allocated to the Member (and
                           earnings thereon) shall then be reduced to the extent
                           necessary to eliminate such remaining Excess Annual
                           Additions. The amount of the reduction of the
                           Employer Contributions for such Member shall be
                           reallocated first out of such Member's unmatched
                           Salary Deferral Contributions, then matching Employer
                           Contribution Account and then out of his Salary
                           Deferral Contribution Account, and shall be held in a
                           suspense account which shall be applied as a part of
                           (and to reduce to such extent what would otherwise
                           be) the matching Employer Contributions for all
                           Members required to be made to the Plan during the
                           next subsequent calendar quarter or quarters. No
                           portion of such Excess Annual Additions may be
                           distributed to Members or former Members. If a
                           suspense account is in existence at any time during
                           the Plan Year pursuant to

                                      IV-7

<PAGE>   26




                           this paragraph B, such suspense account shall not
                           participate in the allocation of investment gains or
                           losses of the Trust Fund.

         (b)      Two or More Defined Contribution Plans

                           (1) If, in addition to this Plan, the Employer
                  maintains any other qualified defined contribution plan, the
                  amount of Annual Additions which may be allocated under this
                  Plan on a Member's behalf for a Plan Year, shall not exceed
                  the lesser of:

                                    A. the Maximum Permissible Amount, reduced
                           by the sum of any Annual Additions allocated to the
                           Member's accounts for the same Plan Year under such
                           other defined contribution plan or plans; or

                                    B. any other limitation contained in this
                           Plan.

                           (2) Prior to the determination of the Member's actual
                  Applicable Compensation for the Plan Year, the amount referred
                  to in Section 4.11(b)(1), may be determined on the basis of
                  the Member's estimated annual Applicable Compensation for such
                  Plan Year. Such estimated annual Applicable Compensation shall
                  be determined on a reasonable basis and shall be uniformly
                  determined for all Members similarly situated.

                           (3) As soon as is administratively feasible after the
                  end of the Plan Year, the amounts referred to in Section
                  4.11(b)(1) shall be determined on the basis of the Member's
                  actual Applicable Compensation for such Plan Year.

                           (4) If a Member's Annual Additions under this Plan
                  and all such other defined contribution plans result in Excess
                  Annual Additions, such Excess Annual Additions shall be deemed
                  to consist of the amounts last allocated.

                           (5) If Excess Annual Additions were allocated to a
                  Member on an allocation date of another plan, the Excess
                  Annual Additions attributed to this Plan will be the product
                  of:

                                    A. the total Excess Annual Additions
                           allocated as of such date (including any amount which
                           would have been allocated but for the limitations of
                           Code Section 415); times

                                    B. the ratio of (A) the amount allocated to
                           the Member as of such date under this Plan, divided
                           by (B) the total amount allocated as of such date
                           under all qualified defined contribution plans
                           (determined without regard to the limitations of Code
                           Section 415).

<PAGE>   27




                           (6) Any Excess Annual Additions attributed to this
                  Plan shall be disposed of as provided in Section 4.11(a).

         (c)      Defined Contribution Plan and Defined Benefit Plan

                           (1) General Rule - If the Employer maintains one or
                  more defined contribution plans and one or more defined
                  benefit plans, the sum of the "defined contribution plan
                  fraction" and the "defined benefit plan fraction," as defined
                  in Code Section 415, cannot exceed 1.0 for any Plan Year. For
                  purposes of this paragraph (c) of Section 4.11, Employee
                  contributions to a qualified defined benefit plan are treated
                  as a separate defined contribution plan, and all defined
                  contribution plans of an Employer are to be treated as one
                  defined contribution plan and all defined benefit plans of an
                  Employer are to be treated as one defined benefit plan whether
                  or not such plans have been terminated.

                           (2) If the sum of the defined contribution plan
                  fraction and defined benefit plan fraction exceeds 1.0, the
                  annual benefit of the defined benefit plan or plans (starting
                  with this Plan first) will be reduced so that the sum of the
                  fractions will not exceed 1.0. In no event will the annual
                  benefit be decreased below the amount of the accrued benefit
                  to date. If additional reductions are required for the sum of
                  the fractions to equal 1.0, the reductions will then be made
                  to the defined contribution plan or plans (starting with this
                  Plan first).

         (d)      Incorporation by Reference

                           All provisions of Code Section 415 that may not be
                  applied in more than one manner are hereby incorporated in the
                  Plan by references and if any such incorporated provision
                  conflicts with a provision in the Plan, such incorporated
                  provision shall control.

4.12     ROLLOVER CONTRIBUTIONS: An Employee who is in the Eligible Class shall
be eligible to make a rollover contribution (whether a "direct" or "indirect"
rollover) to the Plan by wire transfer or by check or other property acceptable
to the Committee, provided such contribution satisfies the requirements of
Section 402(a) of the Code as being a 'qualified rollover,' and the Employee
satisfies such other administrative requirements concerning such rollover
contributions as may be required, including designating the investment fund(s)
for such contribution. Rollover contributions are not subject to an Employer
matching contribution.

4.13     VESTING: Each person who was a Member or an Employee in the Eligible 
Class on June 30, 1998 shall always be 100% vested in all of his Accounts,
except that any Member in the Tacoma Plan who was not an Employee on the date it
was merged into the Plan, shall continue to be vested in his merged Accounts
only to the extent vested therein on the merger date, unless he again becomes an
Employee. Each person who becomes a Member after June 30, 1998 shall always be


                                      IV-9

<PAGE>   28



100% vested in his Savings Contributions, Salary Deferral and Rollover Accounts,
and shall become 100% vested in his Employer Contribution Account based on his
Years of Service in accordance with the following schedule:

             Years of Service                   Vested Percentage
             ----------------                   -----------------  
                less than 3                                0%
                 3 or more                               100%

         Regardless of his Years of Service however, a Participant who is an
Employee on or after reaching age 65 shall be 100% vested in all his Accounts.
Further, in the event a Participant's employment with the Employers and
Affiliated Companies is terminated by reason of disability (as determined for
purposes of Title II of the Federal Social Security Act) or death, he shall also
be deemed to be 100% vested in all his Accounts.

         Notwithstanding the foregoing schedule, in the event the Plan is
terminated or partially terminated or the Employers' contributions under the
Plan are completely discontinued, each affected Member shall thereupon be 100%
vested in all his Accounts as of the date of such discontinuance or termination
or partial termination.

                                   INVESTMENTS

5.1      DIRECTION OF INVESTMENTS:

                  (a) Each Member shall direct, when he authorizes Savings
         Contributions, elects to have made Salary Deferral Contributions or
         makes a Rollover Contribution, that such contributions be invested in
         one or more of the investment funds offered under the Plan (as set
         forth on Attachment A, which is made a part of the Plan for all
         purposes) in increments of 1%; provided, however, a Rollover
         Contribution may not be invested in the Company Stock Fund. Employer
         matching contributions shall be invested in the same manner as the
         Member's contributions with respect to which they are made. The
         Committee may, from time to time, add additional investment funds
         and/or delete existing investment funds offered under the Plan by
         giving advance notice to the Members. The Committee shall have the full
         power and authority to make such rules as necessary or appropriate to
         add or delete a fund, including amending the Plan and Trust to
         effectuate such change.

                  (b) Each Member may change the investment of the existing
         balances in his Accounts, by authorizing a transfer from one investment
         fund to one or more of the other investment funds in 1% increments, as
         of any Valuation Date by giving notice to the Plan's record keeper in
         accordance with the Plan's administrative procedures then in effect;
         provided, however, existing Account balances may not be transferred
         into the Company Stock Fund.

                  (c) Each Member may change the current investment direction
         concerning his future Savings and Salary Deferral Contributions as of
         any Valuation Date by giving notice to the Plan's record keeper in
         accordance with the Plan's administrative procedures then in effect.

5.2      COMPANY STOCK FUND: With respect to the Company Stock Fund, the Trustee
shall vote the shares of Company Stock held in the Company Stock Fund for the
respective Accounts of the Members in accordance with the directions of such
Members, provided such directions are received by the Trustee at least five days
before the date set for the meeting at which such shares are to be voted. The
Trustee shall not vote shares of Company Stock for which it has not received
timely instructions on a particular matter, unless otherwise required by ERISA.
Each Member (or, in the event of his death, his beneficiary) shall have the
right, to the extent of the number of shares of Company Stock allocated to his
Accounts in the Company Stock Fund, respectively, to instruct the Trustee in
writing as to the manner in which to respond to a tender offer or exchange offer
with respect to such shares. The Committee shall use its best efforts timely to
distribute or cause to be distributed to each Member (or beneficiary thereof)
such information as will be distributed to stockholders of the Company in
connection with any such tender offer or exchange offer. Upon timely receipt of
such instructions, the Trustee shall respond as instructed with respect to
shares of such stock. The instructions received by the Trustee from Members
shall be held by the Trustee in

                                       V-1

<PAGE>   30




confidence and shall not be divulged or released to any person, including
officers or employees of the Corporation or any Affiliated Company. If the
Trustee shall not receive timely instructions from a Member (or beneficiary
thereof) as to the manner in which to respond to such tender offer or exchange
offer, such Member (or beneficiary) shall be deemed to have instructed the
Trustee not to tender or exchange the Company Stock.

                                   ARTICLE VI
                    PAYMENT OF CONTRIBUTIONS AND ALLOCATIONS

6.1      PAYMENT OF CONTRIBUTIONS: Each Employer shall, as soon as reasonably
practicable following each payroll period, pay to the Trustee the amounts
representing payroll deductions pursuant to Savings Contributions and the
amounts representing salary reductions pursuant to its Members Salary Deferral
Contributions. Employer Contributions shall be made to the Trustee in full prior
to the due date including extensions thereof, for filing the Employer's federal
income tax return for its taxable year which ends coincident with the end of
such Plan Year or within which such Plan Year ends, as the case may be. The
Trustee shall hold or apply the contributions so received by it in accordance
with the provisions of the Plan; and no part thereof shall be used for any
purpose other than the exclusive benefit of the Members or their beneficiaries.
Contributions shall be made in cash (by check or wire transfer) or, with respect
to Employer Contributions to be invested in the Company Stock Fund, in the sole
discretion of the Corporation, in shares of Company Stock.

6.2      VALUATION OF TRUST FUND: The Trustee shall value the assets of the 
Trust Fund at fair market value as of each Valuation Date. With respect to an
Account (or the portion thereof) that is invested in a mutual fund, the fair
market value shall be determined based on the reported value of a unit in such
fund for the applicable Valuation Date. With respect to an Account (or the
portion thereof) that is invested in the Company Stock Fund, the fair market
value shall be the fair market value of the shares of Company Stock allocated to
such Account on the applicable Valuation Date. The Trustee's determination of
the value of any Account shall be final and conclusive for all purposes of the
Plan.

6.3      FUNDING POLICY: The provisions of Articles IV and VI shall be deemed 
the procedure for establishing and carrying out the funding policy and method of
the Plan. Such funding policy and method shall be administered by the Employers
and other fiduciaries consistent with the objectives of the Plan and with the
requirements of Title I of ERISA.

                            DISTRIBUTION OF ACCOUNTS

7.1      TIME OF DISTRIBUTION: For separations from service occurring after 
1997, if the vested value of the Member's Accounts is less than or equal to
$5,000 (for separations from service prior to 1998, $3,500 shall be substituted
for $5,000 here and below, unless IRS rules permit the $5,000 limit to apply to
such Members), distribution of the Member's Accounts shall be made as soon as
practicable after the Member's separation from service; however, if the total
vested value of the Member's Accounts exceeds (or at the time of any prior
withdrawal or distribution, exceeded) $5,000, the Member's Accounts shall be
distributed only upon his written consent following his separation of service,
but in any event no later than 60 days after the end of the Plan Year in which
occurs the earlier of the Member's death or attainment of age 65. If a Member's
termination of service occurs after attainment of age 65, distribution shall be
made within 60 days after the end of the Plan Year in which termination occurs;
however, Effective January 1, 1997, benefit payments to any Member who reaches
age 70-1/2 prior to 1999 (excluding any 5% or more owner) must begin by April 1
of the calendar year following the year in which the individual attains age
70-1/2, whether or not the person has terminated service, unless such Member
(excluding any 5% or more owner) elects to defer distribution until his
termination of employment. All benefits payable because of a Member's death
shall be paid to the Member's beneficiary in a single, lump-sum distribution as
soon as practicable and in all events within five years of the Member's date of
death. If a Member dies after distributions have begun following his termination
of employment and before his entire interest has been distributed to him, the
remaining portion will be distributed to his beneficiary at least as rapidly as
the method in effect on the Member's date of death.

         Notwithstanding anything in the Plan to the contrary, amounts held in
the Member's Salary Deferral Contribution Account may not be distributable prior
to the earlier of:

                  (a) his separation from service (within the meaning of Code
         Section 401(k)), total and permanent disability, or death;

                  (b) his attainment of age 59-1/2;

                  (c) termination of the Plan without establishment of a
         successor plan by the Employer or an Affiliated Company;

                  (d) the date of the sale by the Employer to an entity that is
         not an Affiliated Company of substantially all of the assets (within
         the meaning of Code Section 409(d)(2)) with respect to a Member who
         continues employment with the corporation acquiring such assets;
         provided the Employer continues to maintain the Plan;

                  (e) the date of the sale by the Employer of its interest in a
         subsidiary (within the meaning of Code Section 409(d)(3)) to an entity
         which is not an Affiliated Company with

                                      VII-1

<PAGE>   33




         respect to a Member who continues employment with such subsidiary;
         provided the Employer continues to maintain the Plan; or

                  (f) proven financial hardship, subject to the limitations of
         Section 7.6, and any distribution due to items (c), (d) or (e) above
         may only be made in a lump sum.

7.2      DISTRIBUTIONS FROM ACCOUNTS FOLLOWING SEPARATION FROM SERVICE: 
Following a Member's separation from service, his Accounts shall be distributed
as follows: subject to Section 7.8, the Member's Accounts shall be distributed
to the Member or his beneficiary, as the case may be, in a lump sum payment in
cash or, with respect to the portion of the Account invested in the Company
Stock Fund, if any, in shares of Company Stock, if elected.

7.3      PARTIAL WITHDRAWALS:

                  (a) Pre-1987 Member Contribution Withdrawals. As of any
         Valuation Date, a Member who is an Employee may, by giving proper
         notice, elect to withdraw from such Member's Pre-1987 Savings
         Contributions Subaccount under his Savings Contribution Account any
         dollar amount of such contributions without investment earnings
         thereon. The amount withdrawn may not exceed the amount of such
         contributions made prior to 1987.

                  (c) Rollover Account Withdrawals. A Member who is an Employee

         above may, as of any Valuation Date, by giving proper notice, elect to
         withdraw all or any part of such Member's Rollover Account.

         Withdrawals shall be in cash unless the Account is invested in the
Company Stock Fund and the Member elects to withdraw shares.

         If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

                                      VII-2

A Member who makes a withdrawal pursuant to this Section shall not be entitled

Deferral Contributions he may make during the following 6-month period.
Withdrawals shall be in cash unless the Account is invested in the Company Stock
Fund and the Member elects to withdraw shares.

         If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.5      SPECIAL WITHDRAWAL AFTER ATTAINMENT OF AGE 59-1/2: Each Member who is 
an Employee, is fully vested, and has attained age 59-1/2 may withdraw all or
any portion of his Employer Contribution Account, and, even if not fully vested,

the following 6-month period.

7.6      HARDSHIP WITHDRAWALS: A Member who is an Employee may request for a 
hardship withdrawal from his Salary Deferral Contribution Account and, if fully
vested, his Employer Contribution Account. The approval or disapproval of such
request shall be made by the Committee. The Committee shall not approve any such
request unless it finds that the Member is facing a hardship creating an
"immediate and heavy financial need" (as defined below) and the Member has
obtained all distributions, other than hardship distributions, and all
nontaxable loans currently available under the Plan and all other plans of the
Employer and its ERISA affiliates. To the extent the Member is fully vested in
his Employer Contribution Account, the withdrawal shall be taken first from that
Account. The amount of the hardship withdrawal shall be limited to an amount
that does not exceed: (1) that amount which the Committee determines to be
required to meet the immediate financial needs created by the hardship, which
may include any amounts necessary to pay any federal, state or local income
taxes or penalties reasonably anticipated to result from the distribution, and
(2) if made from the Participant's Salary Deferral Contribution Account, the
amount of the Salary Deferral Contribution Account, but excluding all earnings
credited to such Account after 1988. Further, if a hardship distribution is made
under the Plan, the restrictions set forth in subparagraph (b) below shall
apply. The hardship withdrawal shall be made in cash as soon as practical after
the date the Member submitted the hardship request. The following standards
shall be applied on a uniform and non-discriminatory basis in determining the
existence of a hardship:

                  (a) A financial need shall be deemed to be an "immediate and
         heavy financial need" if it is on account of:

                           (1) Medical expenses described in section 213(d) of
                  the Code incurred by the Member, the Member's spouse, or any
                  dependents of the Member (as defined in section 152 of the
                  Code) or necessary for these persons to obtain such medical
                  care;

                           (2) Costs directly related to the purchase (excluding
                  mortgage payments) of a principal residence for the Member;

                           (3) Payment of tuition, related educational fees, and
                  room and board expenses for the next 12 months of
                  post-secondary education for the Member, his or her spouse,
                  children, or dependents; or

                           (4) The need to prevent the eviction of the Member
                  from his principal residence or foreclosure on the mortgage of
                  the Member's principal residence; or

                           (5) any other "safe-harbor" event established from
                  time to time by the Internal Revenue Service.

                  (b)      Upon a hardship distribution,

                           (1) The Member's 401(k) contributions and after-tax
                  contributions under the Plan, and all other plans maintained
                  by the Employer and its ERISA affiliates (other than a health
                  or welfare benefit plan or the mandatory employee contribution
                  portion of a defined benefit plan), will be suspended for 12
                  months, and

                           (2) The Member may not make 401(k) contributions
                  under the Plan, and all other plans maintained by the Employer
                  and its ERISA affiliates, for the Member's taxable year
                  immediately following the taxable year of the hardship
                  distribution in excess of the applicable limit under Code
                  Section 402(g) for such next taxable year less the amount of
                  the Member's elective contributions for the taxable year of
                  the hardship distribution.

         Withdrawals shall be in cash unless the Account is invested in the
Company Stock Fund and the Member elects to withdraw shares.

         If the withdrawal made pursuant to this Section 7.3 is with respect to
a contribution that received a matching Employer contribution in the preceding
24 months, the Member shall not be entitled to Employer matching contributions
with respect to any Savings or Salary Deferral Contributions he may make during
the following 6-month period.

7.7      LOANS TO MEMBERS: Loans shall be granted in a uniform and
non-discriminatory manner to Members (as used herein, a Member includes a
beneficiary) from their Accounts, provided the Member is a "party in interest"
under ERISA, subject to the following terms and conditions:


                                      VII-4

<PAGE>   36




                  (a) Loans made pursuant to this Section (when added to the
         outstanding balance of all other loans made by the Plan to the Member)
         shall be limited to the lesser of:

                           (1) $50,000 reduced by the excess (if any) of the
                  highest outstanding balance of loans from the Plan to the
                  Member during the one-year period ending on the day before the
                  date on which such loan is made, over the outstanding balance
                  of loans from the Plan to the Member on the date on which such
                  loan was made, or

                           (2) one-half of the value of the vested portion of
                  the Member's Accounts.

         For purposes of this limit, all plans of the Employer and Affiliated
         Companies shall be considered one plan. Each loan must be for at least
         $1,000.

                  (b) Loans shall provide for the level amortization of
         principal and interest with payments to be made not less frequently
         than monthly over a period not to exceed five years. However, loans
         used to acquire any dwelling unit which, within a reasonable time, is
         to be used (determined at the time the loan is made) as a principal
         residence of the borrower shall provide for periodic repayment over a
         period of time not to exceed ten years. Loans shall be evidenced by a
         note signed by the Member payable in monthly installments. All loans
         shall bear interest at the rate in effect in the commercial loan
         division of the Trustee or an affiliated bank to the Trustee for loans
         of a similar nature on the date the loan is made, and if the Trustee
         does not provide such a rate of interest itself or through an
         affiliated bank, then the rate at any bank handling the Company's
         accounts as determined by the Committee, for loans of a similar nature
         on the date the loan is made.

                  (c) Loans must be repaid by means of an irrevocable payroll
         deduction election, unless the Member is not receiving a salary from
         the Employer that is sufficient to allow deduction of the full loan
         payments, in which case any excess of payments due over the amount
         deductible from the Member's salary shall be paid to the Plan by the
         Member in level installments each pay period, but in no event less
         frequently than monthly. All loans shall become due and payable in full
         upon the date a Member ceases to be a "party in interest" to the Plan.

                  (d) Loans shall be made first from the Rollover Account, then
         the Salary Deferral Contribution Account. If the balance in the Salary
         Deferral Contribution Account is less than the amount of the requested
         loan, the remainder of the loan shall be made next from the Employer
         Contribution Account, and last from the Savings Contribution Account.
         Any loan under the Plan shall be secured by the pledge of all of the
         Member's right, title and interest in an amount of his or her vested
         Accounts equal to the amount of the loan, but not exceeding 50% of such
         vested Accounts as determined immediately after such loan. Such pledge
         shall be executed by the Member and his Spouse, if any, which shall
         provide that, in the event of any default on a loan repayment, the
         Committee shall be authorized to take any and all appropriate lawful
         actions necessary to enforce collection of

                                      VII-5

<PAGE>   37




         the unpaid loan. In addition, the promissory note shall provide that,
         in the event of a default on the loan repayment, both the principal and
         accrued, unpaid interest shall be immediately due and payable. If the
         Member is subject to the provisions of Section 401(a)(11) of the Code
         at the time the vested Accounts are pledged as security for the loan,
         the spousal consent must be obtained in the proper form.

                  (e) A request for a loan shall be made in accordance with the
         Plan's administrative procedures, which may specify the order in which
         the investment fund(s) within each of the Account(s) are invested shall
         be redeemed to make the requested loan, and shall constitute a written
         consent to a distribution or deemed distribution of the Account(s), if
         necessary, in the event of a default. If a request for a loan is
         approved by the Committee, the Committee shall furnish or cause to be
         furnished the Trustee with instructions directing the Trustee to make
         the loan in a lump-sum payment of cash to the Member.

                  (f) A loan shall be considered an investment of the separate
         Account(s) of the Member from which the loan is made. All loan
         repayments of principal and interest shall be credited to such separate
         Account(s) and reinvested in the investment funds in accordance with
         the Member's election in effect for his current contributions, or, if
         none is in effect, his most recent such election.

                  (g) Only two loans may be outstanding at any time to a Member.

                  (h) Loan repayments will be suspended under this Plan as
         permitted under Code Section 414(u)(4).

                  (i) All or part of the reasonable administrative costs of
         establishing and maintaining a loan may be charged to the borrowing
         Member.

7.8      METHODS OF DISTRIBUTION: Distributions shall be made in a lump sum in
cash (and, with respect to Accounts invested in the Company Stock Fund, in
shares of Company Stock, if elected) unless a Member (and his Spouse, if
applicable) have made the proper election to receive one of the following
optional forms of payment.

                  (a) Joint and Survivor Annuity. If a Member is married on the
         benefit payment date and elects not to receive a lump sum, distribution
         shall be in the form of a Joint and Survivor Annuity, which shall be an
         annuity for the life of the Member with a contingent annuity for the
         life of the Member's Spouse, if she survives him, which is 50% of the
         amount of the annuity payable to the Member had he lived. The Joint and
         Survivor Annuity shall be maximum amount that may be obtained by
         purchasing an annuity contract with the Member's Accounts from an
         insurance company selected by the Committee. Subject to Sections 7.9
         and 9.1, a married Member may elect to receive the Single Life Annuity
         or to designate someone other than his Spouse as his contingent joint
         annuitant; provided it must

                                      VII-6

<PAGE>   38




         be expected that the Member will receive more than 50% of the present
         value of his Accounts under such annuity.

                  (b) Single Life Annuity. If a Member who is not married on the
         benefit payment date elects not to receive a lump sum, the Member shall
         receive his distribution in the form of a Single Life Annuity providing
         him with equal monthly payments for his lifetime. The amount of such
         annuity shall be the maximum amount that may be obtained by purchasing
         an annuity contract with the Member's Accounts from an insurance
         company selected by the Committee. Subject to Section 7.9, the Member
         may elect to receive the Joint and Survivor Annuity.

                  (c) A Member may elect to receive his distribution in annual,
         semi-annually, quarterly or monthly installments payable in
         substantially equal amounts continuing over a period certain not
         exceeding the Member's (or the Member's and his beneficiary's joint)
         life expectancy(ies) as of the date such payments begin. At the time of
         the election, the Member must specify the fixed period and the
         frequency of the installments elected. The installment payments shall
         be provided from an insurance company contract purchased with the
         amount of the Accounts.

7.9      ELECTION TO RECEIVE AN ANNUITY: The Committee shall furnish certain 
general information pertinent to the annuities to each Member at least 30 but
not more than 90 days prior to such Member's benefit payment date. The furnished
information shall be in accordance with such regulations as the Secretary of the
Treasury may prescribe and shall include a general explanation of (i) the
annuity, (ii) the Member's right to make, and the effect of an election or
revocation of an election to receive the annuity, and (iii) the rights of the
Spouse with respect to the Joint and Survivor Annuity. The period of time during
which a Member may make the election described in this Section 7.9 shall be at
any time during the 90-day period prior to the Member's benefit payment date.
Any election may be revoked and subsequent elections may be made or revoked at
any time and any number of times during such election period.

7.10     PRE-RETIREMENT SURVIVOR ANNUITY: Except as provided below, if a married
Member who has elected the Joint and Survivor Annuity dies before his benefit
payment date, his Spouse shall receive a Pre-retirement Survivor Annuity
commencing as soon as practicable following the date of the Member's death;
however, the Spouse may direct that the annuity start on any subsequent date
specified by the Spouse which is not later than the date the Member would have
reached age 65. The amount of the annuity (equal monthly payments for the
Spouse's lifetime) shall be the maximum amount that may be obtained with the
Member's Accounts by purchasing an annuity contract from an insurance company
selected by the Committee.

         A Spouse who is entitled to receive the Pre-retirement Survivor Annuity
may elect to receive a lump sum payment of the Member's Accounts in lieu of the
annuity by furnishing the Committee the proper form at any time prior to the
date such insurance contract is purchased.


                                      VII-7

<PAGE>   39




7.11     ELECTION NOT TO RECEIVE THE PRE-RETIREMENT SURVIVOR ANNUITY: A Member 
who has elected to receive the Joint and Survivor Annuity may elect, by
executing the election form prescribed by the Committee, not to be covered by
the Pre-retirement Survivor Annuity. Such election must be made during the
election period described below. Any election may be revoked and subsequent
elections may be made or revoked at any time during such election period. Any
such election and any revocation of such election must be signed by the Member's
Spouse and acknowledge the effect of such election on the Spouse's right to
benefits and further, the Spouse's signature must be notarized, and designate a
specific beneficiary and the specific form of payment that cannot be changed
without a new spousal consent.

         The Committee shall furnish certain general information pertinent to
this election to each Member within the period beginning on the first day of the
Plan Year in which the Member attains age 32 and ending with the close of the
Plan Year preceding the Plan Year in which the Member attains age 35. With
respect to an Employee who becomes a Member of the Plan after the date the
general information is required to be furnished, such information shall be
furnished on or about the date that such Member begins participation in the
Plan. The furnished information shall be written in accordance with such
regulations as the Secretary of Treasury may prescribe and shall contain a
general explanation of (i) the terms and conditions of Pre-retirement Survivor
Annuity (ii) the Member's right to make and the effect of, an election or
revocation of an election to waive the Pre-retirement Survivor Annuity, and
(iii) the rights of the Member's Spouse with respect to the Pre-retirement
Survivor Annuity. The Member may make or revoke the election described in this
Section 7.11 at any time.

7.12     DIRECT ROLLOVER: Notwithstanding any provision of the Plan to the 
contrary that would otherwise limit a distributee's election under this Section,
a distributee may elect, at the time and in the manner prescribed by the
Committee, to have any portion of an eligible rollover distribution paid
directly to an eligible retirement plan specified by the distributee in a direct
rollover.

         Eligible rollover distribution: An eligible rollover distribution is
any distribution of all or any portion of the balance to the credit of the
distributee, except that an eligible rollover distribution does not include: any
distribution that is one of a series of substantially equal periodic payments
(not less frequently than annually) made for the life (or life expectancy) of
the distributee or the joint lives (or joint life expectancies) of the
distributee and the distributee's designated beneficiary, or for a specified
period of ten years or more; any distribution to the extent such distribution is
required under section 401(a)(9) of the Code; and the portion of any
distribution that is not includible in gross income (determined without regard
to the exclusion for net unrealized appreciation with respect to employer
securities).

         Eligible retirement plan: An eligible retirement plan is an individual
retirement account described in section 408(a) of the Code, an individual
retirement annuity described in section 408(b) of the Code, an annuity plan
described in section 403(a) of the Code, or a qualified trust described in
section 401(a) of the Code, that accepts the distributee's eligible rollover
distribution. However,

                                      VII-8

<PAGE>   40




in the case of an eligible rollover distribution to the surviving spouse, an
eligible retirement plan is an individual retirement account or individual
retirement annuity.

         Distributee: A distributee includes an Employee or former Employee. In
addition, the employee's or former Employee's surviving spouse and the
Employee's or former Employee's spouse or former spouse who is the alternate
payee under a qualified domestic relations order, as defined in section 414(p)
of the Code, are distributees with regard to the interest of the spouse or
former spouse.

         Direct rollover: A direct rollover is a payment by the plan to the
eligible retirement plan specified by the distributee.

7.13 30-DAY WAIVER: If a distribution is one to which sections 401(a)(11) and
417 of the 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 Committee clearly informs the Member that the Member
         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 Member, after receiving the notice, affirmatively
         elects a distribution.

7.14     FORFEITURES: Upon a Member's termination of employment with the 
Employers and Affiliated Companies the nonvested portion of the Member's
Employer Contributions Account (if any) shall continue to be held in the Trust
until forfeited as of the earlier of the date the Member incurs five consecutive
Breaks in Service or receives a complete distribution of his vested Accounts.
Forfeited account balances shall be used to reduce future Employer contributions
otherwise due under the Plan. However, if a Member again becomes an Employee in
the Eligible Class prior to incurring five consecutive Breaks in Service, his
forfeited amount shall be restored, unadjusted for any interim Trust fund gains
or losses, through a special allocation of then existing forfeitures and/or
additional Employer contributions, provided the Member repays the full amount of
such prior distribution to the Plan in cash before the fifth anniversary of his
reemployment date or prior to incurring five consecutive Breaks of Service,
whichever occurs first.

                       BENEFICIARIES IN THE EVENT OF DEATH

9.1      BENEFICIARIES: Upon the death of a Member, his Vested Accounts shall be
distributed to the beneficiary or beneficiaries designated by him in a written
designation on a Plan form filed with his Employer or, if no such designation
shall have been so filed, to his Spouse or, if none, to his estate. No such
designation of beneficiary shall be effective (whether or not made prior to
marriage) if the Member has a Spouse as of his date of death, unless such Spouse
is designated as the sole beneficiary, or unless such Spouse consents to the
designation of another specified person (and form of payment) as beneficiary.
The Spouse's consent must be in writing, acknowledge the effect of the consent
on the Spouse's right to benefits under the Plan, and be witnessed by a Plan
representative or a notary public. The beneficiary designated by the Member may
not be changed without the Spouse's consent, however, a revocation of a
designation of a beneficiary other than the Spouse may be made by a Member
without the consent of the Spouse at any time before the distribution of the
benefit under the Plan. The Spouse's consent to a beneficiary designation shall
not be required if it is established to the satisfaction of the Committee that
such written consent may not be obtained because there is no Spouse or the
Spouse cannot be located. Any consent under this Article IX will be valid only
with respect to the Spouse who signs the consent. The divorce of a Member shall
automatically revoke such former spouse as his beneficiary under the Plan,
except to the extent otherwise provided in a qualified domestic relations order.

                                 ADMINISTRATION

10.1     ADMINISTRATIVE COMMITTEE: The Corporation shall act as the 
administrator of the Plan and shall have all of the powers and responsibilities
conferred upon administrators under ERISA. However, an Administrative Committee
composed of such persons, as may be determined from time to time by the Board of
Directors, may be appointed by the Board to perform the duties of the
Corporation.

         The Committee shall elect a Chairman from its number, and a Secretary,
and such other officers as the Committee may determine, who may, but need not,

Secretary shall keep a record of all meetings and forward all necessary
communications to the Companies and the Trustee. The Chairman of the Committee
shall be agent of the Plan and the Committee for the service of legal process.

         Any person appointed a member of the Committee shall signify his
acceptance by filing written acceptance with the Board of Directors. Any member

of Directors, and such resignation shall become effective at delivery or at any
later date specified therein.

         No member of the Committee who is also an officer or employee of any of
the Companies receiving compensation as such shall receive any compensation for
his services as such member. No bonds or other security shall be required of any
member except as required by law.

relating solely to his own Account or any other right or privilege under the
Plan.

                  (c) To employ such agents and assistants, such counsel (who

                  (d) To authorize one or more of their number, or any agent, to
         make any payment, or to execute or deliver any instrument, on behalf of
         the Committee, except that all

                                       X-1

<PAGE>   44




         requisitions for funds from, and requests, directions, notifications,
         certifications, and instructions to, the Trustee or to the Company or
         Affiliated Companies shall be signed on behalf of the Committee by two

         shall be the Secretary or Assistant Secretary thereof;

                  (e) To fix and determine the proportions of costs of the Plan
         from time to time to be paid by the Company or Affiliated Companies;

                  (f) To determine, from the records of the Company or

         facts regarding Employees;

                  (g) To construe and interpret the Plan, decide all questions
         of eligibility and determine the amount, manner and time of payment of
         any benefits hereunder;

                  (h) To prescribe forms and procedures to be followed by
         Employees applying for membership, Members electing or changing Savings
         Contributions or Salary Deferral Contributions, Members or
         beneficiaries filing applications for benefits, Members applying for
         withdrawals, and other occurrences in the administration of the Plan;

                  (i) To prepare and distribute, in such manner as the Committee
         determines to be appropriate, information explaining the Plan;

                  (j) To receive from the Company, or Affiliated Companies, and

         administering the Plan and carrying out its Provisions and performing
         the duties imposed upon the Committee.

10.3     DUTIES OF THE COMMITTEE: The Committee shall have the general
responsibility for administering the Plan and carrying out its provisions;
subject, however, to the provisions of the Plan and the Trust Agreement.


                                       X-2

<PAGE>   45




         Subject to the limitations of the Plan, the Committee, from time to
time, shall establish rules for the administration of the Plan and the
transaction of its business. As to all matters of administration not reserved in
the Plan to the Board of Directors or the Boards of Directors of the Employers,
the determination of the Committee as to any disputed question shall be
conclusive. All such rules and decisions of the Committee shall be uniformly and
consistently applied in order that all Members in similar circumstances shall be
treated alike.

         It shall be the duty of the Committee to notify the Trustee in writing
of the termination of service of any Member under the Plan and of the amount of
cash which shall be payable to such Member upon termination of service, and the
date distributions are to commence. The Committee shall not requisition any
payment from the Trustee except upon certification by the Committee that such
amount is for payment of benefits under the Plan or for the payment of expenses
of administering the Plan. Any such certification by the Committee shall be
deemed conclusively true insofar as the Trustee is concerned.

         All resolutions or other actions taken by the Committee at the meeting
shall be by vote of the majority of the Committee attending the meeting.

10.4     ACCOUNTS RECORDS: The Committee shall maintain accounts showing the 
fiscal transactions of the Plan and shall keep, or cause the Employers to keep,
in convenient form, such data as may be necessary for valuation of the assets.
The Committee shall prepare annually a report showing in reasonable summary the
assets and liabilities of the Plan and giving a brief account of the operation
of the Plan for the past Plan Year and any further information which the Boards
of Directors of the Employers may require and as the Committee can reasonably
furnish or can obtain from the Trustee. Such report shall be submitted to the
Boards of Directors of the Employers and shall be filed in the office of the
Secretary of the Committee, where it shall be open to inspection by any Member.
The Committee shall exercise such other authority and responsibility as it deems
appropriate in order to comply with ERISA and governmental regulations issued
thereunder relating to (i) records of Members' service, Account balances and the
percentage of such Account balances which are nonforfeitable under the Plan;
(ii) notifications to Members; and (iii) annual reports to the Internal Revenue
Service. Unless otherwise required by law, the Committee may authorize any
method of accounting for, or of reporting, information with respect to Plan
assets and Account balances which fairly and accurately presents the fair market
value, determined in accordance with the Plan, of the Plan assets and Account
balances as of such date.

10.5     ALLOCATION OF RESPONSIBILITY AMONG FIDUCIARIES FOR PLAN AND TRUST FUND
ADMINISTRATION: The fiduciaries of the Plan shall have only those specific
powers, duties, responsibilities and obligations as are specifically given them
under this Plan or the Trust Agreement. In general, the Companies shall have the
sole responsibility for making the contributions provided under Article IV. The
Board of Directors shall have the sole authority to appoint and remove the
Trustee, members of the Committee and to amend or terminate, in whole or in
part, this Plan or the Trust. The Committee shall have the sole responsibility
for the administration of this Plan, which responsibility is specifically
described in this Plan and the Trust. The Committee shall have the sole
responsibility

                                       X-3

<PAGE>   46




for selecting an entity to hold and manage the assets in the Plan and for
selecting a guaranteed investment contract(s) to be acquired by the Trustee. The
Trustee shall have the sole responsibility for the administration of the Trust
Fund and the management of the assets held under the Trust, except when an
Investment Manager has been appointed by the Committee, all as specifically
provided in the Trust. Each fiduciary shall warrant that any directions given,
information furnished, or action taken by it shall be in accordance with the
provisions of the Plan or the Trust Agreement, as the case may be, authorizing
or providing for such direction, information or action. Furthermore, each
fiduciary may rely upon any such direction, information or action of another
fiduciary as being proper under this Plan or the Trust, and is not required
under this Plan or the Trust Agreement to inquire into the propriety of any such
direction, information or action. It is intended under this Plan and the Trust
Agreement that each fiduciary shall be responsible for the proper exercise of
its own powers, duties, responsibilities and obligations under this Plan and the
Trust and shall not be responsible for any act or failure to act of another
fiduciary. No fiduciary guarantees the Trust Fund in any manner against
investment loss or depreciation in asset value.

10.6     PRESENTING CLAIMS FOR BENEFIT: Any Member or any beneficiary claiming 
under a deceased Member, may submit written application to the Committee for the
payment of any benefit asserted to be due him under the Plan. Such application
shall set forth the nature of the claim and such other information as the
Committee may reasonably request. Promptly upon the receipt of any application
required by this Section 10.6, the Committee shall determine whether or not the
Member or beneficiary involved is entitled to a benefit hereunder and, if so,
the amount thereof and shall notify the claimant of its findings.

         If a claim is wholly or partially denied, the Committee shall so notify
the claimant within 90 days after receipt of the claim by the Committee, unless
special circumstances require an extension of time for processing the claim. If
such an extension of time for processing is required, written notice of the
extension shall be furnished to the claimant prior to the end of the initial
90-day period. In no event shall such extension exceed a period of 90 days from
the end of such initial period. The extension notice shall indicate the special
circumstances requiring an extension of time and the date by which the Committee
expects to render its final decision. Notice of the Committee's decision to deny
a claim in whole or in part shall be set forth in a manner calculated to be
understood by the claimant and shall contain the following:

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

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

                  (c) a description of any additional material or information
         necessary for the claimant to perfect the claim and an explanation of
         why such material or information is necessary, and

                  (d) an explanation of the claims review procedure set forth in
         Section 10.7 hereof.

                                       X-4

<PAGE>   47




         If notice of denial is not furnished, and if the claim is not granted
within the period of time set forth above, the claim shall be deemed denied for
purposes of proceeding to the review stage described in Section 10.7.

10.7     CLAIM REVIEW PROCEDURE: If an application filed by a Member or 
beneficiary under Section 10.6 above shall result in a denial by the Committee
of the benefit applied for, either in whole or in part, such applicant shall
have the right, to be exercised by written application filed with the Committee
within 60 days after receipt of notice, of the denial of his application or, if
no such notice has been given, within 60 days after the application is deemed
denied under Section 10.6 to request the review of his application and of his
entitlement to the benefit applied for. Such request for review may contain such
additional information and comments as the applicant may wish to present. Within
60 days after receipt of any such request for review, the Committee shall
reconsider the application for the benefit in light of such additional
information and comments as the applicant may have presented, and if the
applicant shall have so requested, shall afford the applicant or his designated
representative a hearing before the Committee. The Committee shall also permit
the applicant or his designated representative to review pertinent documents in
its possession, including copies of the plan document and information provided
by the Company relating to the applicant's entitlement to such benefit. The
Committee shall make a final determination with respect to the applicant's
application for review as soon as practicable, and in any event not later than
60 days after receipt of the aforesaid request for review, except that under
special circumstances, such as the necessity for holding a hearing, such 60-day
period may be extended to the extent necessary, but in no event beyond the
expiration of 120 days after receipt by the Committee of such request for
review. If such an extension of time for review is required because of special
circumstances, written notice of the extension shall be furnished to the
applicant prior to the commencement of the extension. Notice of such final
determination of the Committee shall be furnished to the applicant, in writing,
in a manner calculated to be understood by him, and shall set forth the specific
reasons for the decision and specific references to the pertinent provisions of
the Plan upon which the decision is based. If the decision on review is not
furnished within the time period set forth above, the claim shall be deemed
denied on review.

10.8     DISPUTED BENEFIT: If any dispute shall arise between a Member or other
person claiming under a Member and the Committee after the review of a claim for
benefits, or in the event any dispute shall develop as to the person to whom the
payment of any benefit under the Plan shall be made, the Trustee may withhold
the payment of all or any part of the benefits payable hereunder to the Member
or other person claiming under the Member until such dispute has been resolved
by a court of competent jurisdiction or settled by the parties involved.

10.9     UNCLAIMED BENEFIT: If at, after, or during the time when a benefit
hereunder is payable to any Member, beneficiary or other distributee, the
Committee, upon request of the Trustee, or at its own instance, shall mail by
registered or certified mail to such Member, beneficiary or distributee, at his
last known address a written demand for his then address or for satisfactory
evidence of his continued life, or both, and if such Member, beneficiary or
distributee shall fail to furnish the same to the Committee within two years
from the mailing of such demand, then the Committee may, in

                                       X-5

<PAGE>   48




its sole discretion, determine that such Member, beneficiary or other
distributee has forfeited his right to such benefit and may declare such
benefit, or any unpaid portion thereof, terminated as if the death of the
distributee (with no surviving beneficiary) had occurred on the date of the last
payment made thereon, or on the date such Member, beneficiary or distributee
first became entitled to receive benefit payments, whichever is later; provided,
however, that such forfeited benefit shall be reinstated if a claim for the same
is made by the Member, beneficiary or other distributee at any time thereafter.
Reinstatement shall be made by Company contributions or forfeitures, if any.

11.1     ESTABLISHMENT: A Trust Fund shall be established, operated and 
maintained exclusively for the collective investment and reinvestment of moneys
received from Members and Employers, in accordance with the investment
directions of Members, and the Trust Fund shall be under the exclusive
management and control of the Trustee, except when and for the specific purposes
that an Investment Manager has been properly appointed and is acting pursuant to
direction of the Committee.

11.2     EXCLUSIVE INVESTMENTS: The Trustee shall invest moneys in the Trust 
Fund exclusively in the investments funds provided for under the Plan.

11.3     BENEFICIAL INTERESTS: Each Member shall have a beneficial interest in 
the Trust Fund. No Member shall have priority or preference over any other
Member as to any assets of the Plan.

11.4     SEPARATE ACCOUNTS: The Committee shall maintain separate accounts for 
each Member to reflect each Member's interest in the Trust Fund. Each Member
shall have an Employer Contribution Account, a Savings Contribution Account, a

                                   ARTICLE XII
               TERMINATION, AMENDMENT AND MODIFICATION OF THE PLAN

12.1     POWERS RESERVED: The Corporation, by action of its Board of Directors,
may terminate the Plan in its entirety, or as to any Employer at any time, or
may at any time, or from time to time, amend or modify it, except that no
amendment or modification shall reduce (directly or indirectly) an accrued
benefit, eliminate an optional form of benefit (except as otherwise permitted by
regulations) or adversely change the vesting schedule with respect to any
Employee who is credited with three or more years of service. In addition the
Committee may amend the Plan, subject to the foregoing limitations, provided
that any amendment by the Committee may not materially increase the
Corporation's obligations under the Plan. Any such termination, amendment or
modification shall be effective at such date as the Corporation may determine.
An amendment or modification to the Plan may be effective as to all Companies or
as to any one of them, and their respective employees. An amendment or
modification which increases the duties of the Trustee may be made only with the
consent of the Trustee. An amendment or modification may affect Members in the
Plan at the time thereof, as well as future Members, but may not diminish the
account of any Member as of the effective date of amendment or modification
unless required by the Internal Revenue Service in order for the plan to
continue to be a qualified plan under Code Section 401.

12.2     EFFECT OF TERMINATION: Upon any total or partial termination of the 
Plan or upon discontinuance of contributions by any Employer, each affected
Member, as to whom the Plan is terminated, or as to whom Employer Contributions
have been discontinued, shall receive a fully vested interest in his Accounts.
Upon a termination of the Plan, distribution shall be made only in accordance
with the modes of distributions provided for under the Plan and subject to their
requirements; provided, however, written consent with respect to accounts
greater than $5,000 shall not be required if the Corporation and the Affiliated
Companies do not maintain any other defined contribution plan.

12.3     MERGER OF PLAN WITH ANOTHER PLAN: In the event of any merger or
consolidation of the Plan with, or transfer in whole or in part of the assets
and liabilities of the Trust Fund to another trust fund held under any other
plan of deferred compensation maintained or to be established for the benefit of
all or some of the Members of this Plan, the assets of the Trust Fund
attributable to such Members shall be transferred to the other trust fund only
if:

                  (a) Each Member would (if either this Plan or the other plan
         then terminated) receive a benefit immediately after the merger,
         consolidation or transfer which is equal to or greater than the benefit
         he would have been entitled to receive immediately before the merger,
         consolidation or transfer (if this Plan had then terminated);

                  (b) Resolutions of the Board of Directors of the Employer
         under this Plan, or of any new or successor employer of the affected
         Members, shall authorize such transfer of assets; and, in the case of
         the new or successor employer of the affected Members, its

                                      XII-1

<PAGE>   51




         resolutions shall include an assumption of liabilities with respect to
         such Member's inclusion in the new employer's Plan; and

                  (c) Such other plan and trust are qualified under Code
         Sections 401(a) and 501(a).

13.1     EXPENSES: Unless paid by the Plan, all costs and expenses incurred in
the administration hereof, including the expenses of the Committee, the fees and
expenses of the Trustee, the fees of counsel, and other administrative expenses
shall be paid by the Plan, unless the Employers voluntarily pay any of such
expenses, in which event they shall be ratably shared by the several Employers.

13.2     TAXES: Taxes, if any, on any assets held hereunder by the Trustee, or 
upon income therefrom, which are payable by the Trustee, shall be charged
against such assets or income and allocated as the Trustee and the Committee
shall determine.

                            MISCELLANEOUS PROVISIONS

14.1     TERMS OF EMPLOYMENT: The adoption and maintenance of the provisions of
this Plan shall not be deemed to constitute a contract between any Employer and
Employee, or to be a consideration for, or an inducement or condition of, the
employment of any person. Nothing herein contained shall be deemed to give to
any Member the right to be retained in the employ of an Employer or to interfere
with the right of an Employer to discharge a Member at any time, nor shall it be
deemed to give to an Employer the right to require any Member to remain in its
employ, nor shall it interfere with any Member's right to terminate his
employment at any time.

14.2     CONTROLLING LAWS; GOVERNMENT REGULATIONS: Except to the extent 
preempted by applicable federal law, this Plan shall be construed, regulated and
administered under the laws of the State of Texas. The Plan, and the purchase
and sale of securities pursuant thereto, and the obligations of the Trustee
thereunder to purchase or sell securities, shall be subject to all applicable
laws, rules and regulations, and to such approvals by any governmental agencies
or national securities exchanges as may be required.

14.3     INVALIDITY OF PARTICULAR PROVISIONS: In the event any provision of this
Plan shall be held illegal or invalid for any reason, said illegality or
invalidity shall not affect the remaining provisions of this Plan but shall be
fully severable, and this Plan shall be construed and enforced as if said
illegal or invalid provisions had never been inserted therein.

14.4     NON-ALIENABILITY OF RIGHTS OF MEMBERS: No interest, right or claim in 
or to any part of the Trust 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 shall not recognize any attempt to assign, transfer, sell, mortgage,
pledge, hypothecate, commute or anticipate the same. The foregoing shall also
apply to the creation, assignment, or recognition of a right to any benefit
payable with respect to a Member pursuant to a domestic relations order, unless
such order is determined to be a qualified domestic relations order ("QDRO"), as
defined in Code Section 414(p); provided, however, to the extent directed or
authorized by a QDRO, the Plan may make a distribution prior to a Member's
"earliest retirement age," as defined in Section 414(p) of the Code.

14.5     PAYMENTS IN SATISFACTION OF CLAIMS OF MEMBERS: Any payment or 
distribution to any Member or his legal representative or any beneficiary in
accordance with the provisions of this Plan shall be in full satisfaction of all
claims under the Plan against the Trust Fund, the Trustee and the Employer. The
Trustee may require that any distributee execute and deliver to the Trustee a
receipt and a full and complete release as a condition precedent to any payment
or distribution under the Plan.

14.6     PAYMENTS DUE MINORS AND INCOMPETENTS:  If the Committee determines that
any person to whom a payment is due hereunder is a minor or is incompetent by
reason of physical or mental

                                      XIV-1

<PAGE>   54




disability, the Committee shall have power to cause the payment becoming due
such person to be made to another for the benefit of such minor or incompetent,
without the Committee or the Trustee being responsible to see to the application
of such payment. Payment made pursuant to such power shall operate as a complete
discharge of the Committee, the Trustee and the Employer.

14.7     ACCEPTANCE OF TERMS AND CONDITIONS OF PLAN BY MEMBERS: Each Member, by
making application to become a Member under this Plan, or by the execution of
any form authorized under the terms of this Plan for himself, his heirs,
executors, administrators, legal representatives and assigns, approves and
agrees to be bound by the provisions of this Plan and the Trust and any
subsequent amendments thereto, and all actions of the Committee and the Trustee
hereunder.

14.8     IMPOSSIBILITY OF DIVERSION OF TRUST FUND: Notwithstanding any provision
herein to the contrary, no part of the corpus or the income of the Trust Fund
shall ever be used for, or diverted to, purposes other than for the exclusive
benefit of the Members or their beneficiaries or for the payment of expenses of
the Plan. Except as otherwise provided in Section 15.9, no part of the Trust
Fund shall ever directly or indirectly revert to the Employer.

14.9     REFUNDS TO EMPLOYER: Once contributions are made to the Plan by the
Employer on behalf of the Members, they are not refundable to the Employer
unless a contribution:

                  (a)      was made by mistake of fact; or

                  (b) was made conditioned upon the contribution being allowed
         as a deduction and such deduction was disallowed.

Any contribution made by the Employer during any Plan Year in excess of the
amount deductible or any contribution attributable to a good faith mistake of
fact shall be refunded to the Employer. The amount which may be returned to the
Employer is the excess of the amount contributed over the amount that would have
been contributed had there not occurred a mistake of fact or the excess of the
amount contributed over the amount deductible, as applicable. A contribution
made by reason of a mistake of fact may be refunded only within one year
following the date of payment. Any contribution to be refunded because it was
not deductible under Code Section 404 may be refunded only within one year
following the date the deduction was disallowed. Earnings attributable to any
such excess contribution may not be withdrawn, but losses attributable thereto
must reduce the amount to be returned. In no event may a refund be due which
would cause the Account balance of any Member to be reduced to less than the
Member's Account balance would have been had the mistaken amount, or the amount
determined to be nondeductible, not been contributed.

                              AFFILIATED COMPANIES

15.1     ELIGIBILITY AND ADOPTION: Any Affiliated Company approved by the Board
of Directors may participate as an Employer in the Plan upon the following
conditions:

                  (a) Such Affiliated Company shall make, execute and deliver
         such instruments and take such other action as the Corporation or the
         Committee shall deem necessary or desirable.

                  (b) Such Affiliated Company shall appoint the Corporation as
         its agent to act for it in all transactions in which the Corporation
         believes such agency will facilitate the administration of the Plan.

                                   ARTICLE XVI
                           TOP-HEAVY PLAN REQUIREMENTS

16.1     GENERAL RULE: For any Plan Year for which this Plan is a Top-Heavy 
Plan, as defined in Section 16.6, and despite any other provisions of this Plan
to the contrary, this Plan shall be subject to the provisions of this Article
XVI.

16.2     VESTING PROVISIONS: Each Member who has completed an Hour of Service 
after the Plan becomes top-heavy shall be immediately 100% vested in his account
under this Plan.

16.3     MINIMUM CONTRIBUTION PROVISIONS: Each Member who (i) is a Non-Key 
Employee, and (ii) is employed on the last day of the Plan Year (regardless of
whether the Member has completed 1,000 Hours of Service during the Plan Year,
made a required contribution that year, or his level of compensation), will be
entitled to have contributions and forfeitures allocated to his account of not
less than 3% (the "Minimum Contribution Percentage") of the Member's
Compensation. This Minimum Contribution Percentage will be reduced for any Plan
Year to the percentage at which contributions (including forfeitures) are made
or are required to be made under the Plan for the Plan Year for the Key Employee
for whom such percentage is the highest for such Plan Year. If the Member also
participates in a defined benefit plan of the Employer that is top heavy, he
shall receive the minimum under such defined benefit plan rather than this Plan.

         Contributions considered under the first paragraph of this Section 16.3
will include Employer contributions under this Plan and under all other defined
contribution plans required to be included in an Aggregation Group, but will not
include Employer Contributions under any plan required to be included in such
Aggregation Group if the plan enables a defined benefit plan required to be
included in such group to meet the requirements of the Code prohibiting
discrimination as to contributions in favor of employees who are officers,
shareholders, or the highly compensated or prescribing the minimum participation
standards. If the highest rate allocated to a Key Employee for a year in which
the plan is top-heavy is less than 3%, amounts contributed as a result of a
salary reduction agreement must be included in determining contributions made on
behalf of Key Employees.

         Contributions considered under this Section will not include any
contributions under the Social Security Act or any other federal or state law.

16.4     LIMITATION ON CONTRIBUTIONS: In the event that the Company, other 
Employer or an Affiliated Company (hereinafter in this Article collectively
referred to as a "Considered Company") also maintains a defined benefit plan
providing benefits on behalf of Members in this Plan, one of the two following
provisions will apply:

                  (a) If, for the Plan Year, this would not be a Top-Heavy Plan
         if "90%" were substituted for "60%", in Section 16.6, then the
         percentage of 3% used in Section 16.3 is changed to 4%.

                                      XVI-1

<PAGE>   57




                  (b) If, for the Plan Year, this Plan would continue to be a
         Top-Heavy Plan if "90%" were substituted for "60%", in Section 16.6,
         then the denominator of both the defined contribution plan fraction and
         the defined benefit plan fraction will be calculated as set forth in
         Section 4.11 for the limitation year ending in such Plan Year by
         substituting "1.0" for "1.25" in each place such figure appears. This
         subsection (b) will not apply for such Plan Year with respect to any
         individual for whom there are no (i) Employer Contributions,
         forfeitures or voluntary nondeductible contributions allocated to such
         individual, or (ii) accruals earned under the defined benefit plan.

16.5     UNIFORM ACCRUAL: For Plan Years beginning after December 31, 1986, a
uniform benefit accrual rate must be used in determining whether a plan is
top-heavy or super top-heavy. If all of the employer's plans accrue benefits at
the same rate, that accrual rate is to be used to determine if its plans are
top-heavy or super top-heavy. If no single accrual rate is used uniformly by all
of the Employer's plans, the slowest accrual rate permitted under the fractional
method must be used to determine the accrued benefit for Non-Key Employees.

16.6     DETERMINATION OF TOP-HEAVY STATUS: The Plan will be a Top-Heavy Plan 
for any Plan Year if, as of the Determination Date, the aggregate of the
accounts under the Plan for Members (including former Members) who are Key
Employees exceeds 60% of the aggregate of the accounts of all Members, excluding
former Key Employees, or if this Plan is required to be in an Aggregation Group
in any such Plan Year in which such Group is a Top-Heavy Group. In determining
Top-Heavy status, if an individual has not performed any services for any
Affiliated Company at any time during the five-year period ending on the
Determination Date, any accrued benefit for such individual and the aggregate
accounts of such individual shall not be taken into account.

         In determining whether this Plan constitutes a Top-Heavy Plan, the
Committee (or its agent) will make the following adjustments:

                  (a) When more than one plan is aggregated, the Committee shall
         determine separately for each plan as of each plan's Determination Date
         the present value of the accrued benefits (for this purpose using the
         actuarial assumptions set forth in the applicable plan) or account
         balance. The results shall then be aggregated by adding the results of
         each plan as of the Determination Dates for such plans that fall within
         the same calendar year.

                  (b) In determining the present value of the cumulative accrued
         benefit or the amount of the account of any Employee, such present
         value or account will include the amount in dollar value of the
         aggregate distributions made to such employee under the applicable plan
         during the five-year period ending on the Determination Date unless
         reflected in the value of the accrued benefit or account balance as of
         the most recent Valuation Date. The amounts will include distributions
         to employees representing the entire amount credited to their accounts
         under the applicable plan.

<PAGE>   58




                  (c) Further, in making such determination, such present value
         or such account shall include any rollover contribution (or similar
         transfer), as follows:

                           (1) If the rollover contribution (or similar
                  transfer) is initiated by the Employee and made to or from a
                  plan maintained by another Affiliated Company, the plan
                  providing the distribution shall include such distribution in
                  the present value or such account; the plan accepting the
                  distribution shall not include such distribution in the
                  present value or such account unless the plan accepted it
                  before December 31, 1983.

                           (2) If the rollover contribution (or similar
                  transfer) is not initiated by the employee or made from a plan
                  maintained by another Affiliated Company, the plan accepting
                  the distribution shall include such distribution in the
                  present value or such account, whether the plan accepted the
                  distribution before or after December 31, 1983; the plan
                  making the distribution shall not include the distribution in
                  the present value or such account.

                  (d) In any case where an individual is a Non-Key Employee with
         respect to an applicable plan, but was a Key Employee with respect to
         such plan for any prior Plan Year, any accrued benefit and any account
         of such Employee will be altogether disregarded. For this purpose, to
         the extent that a Key Employee is deemed to be a Key Employee if he or
         she met the definition of Key Employee within any of the four (4)
         preceding Plan Years, this provision will apply following the end of
         such period of time.

         IN WITNESS WHEREOF, the Corporation has caused these presents to be
executed by its authorized individual, in a number of copies, all of which shall
constitute but one and the same instrument, which may be evidenced by any such
executed copy hereof, this June __, 1998, effective for all purposes as provided
above.

                          separate nondiscrimination test.

                 -- (ii)  If option 1, 2, or 3 is elected, you must elect the
                          same definition of Compensation in Section XIII,
                          Limitations on Allocations.

                 -- (iii) Options 1-6 include lump sum amounts and/or cash
                          bonuses. These amounts are included in compensation

                 -- (iv)  Options 4-9 may not be elected by a plan that uses an

                          9 for nondiscrimination testing requires that the 
                          employer satisfy a separate compensation
                          nondiscrimination test.

                                 that the sum of the fraction equals 1.0. Any

                                 exceeded because of an Excess Amount, such
                                 Excess Amount will be reduced in accordance

Dear Applicant:

In our opinion, the form of the plan identified above is acceptable under
Section 401 of the Internal Revenue Code for use by employers for the benefit of
their employees. This opinion relates only to the acceptability of the form of
the plan under the Internal Revenue Code. It is not an opinion of the effect of
other Federal or other local statutes.

You must furnish a copy of this letter to each employer who adopts this plan.
You are also required to send a copy of the approved form of the plan, any
approved amendments and related documents to each Key District Director of
Internal Revenue Service in whose jurisdiction there are adopting employers.

Our opinion on the acceptability of the form of the plan is not a ruling or
determination as to whether an employer's plan qualifies under Code section
401(a). Therefore, an employer adopting the form of the plan should apply for a
determination letter by filing an application with the Key District Director of
Internal Revenue Service on Form 5307, Short Form Application for Determination
for Employee Benefit Plan.

Because you submitted this plan for approval after March 31, 1991, the
continued, interim and extended reliance provisions of sections 13 and 17.03 of
Rev. Proc. 89-9, 1989-1 C.B. 780, are not applicable.

Because you submitted this plan on or after July 1, 1994, it does not meet the
requirements for the extension of the remedial amendment period provided by Rev.
Proc. 95-12, 1995-3 I.R.S. 24.

This letter may not be relied upon with respect to whether the plan satisfies
the qualification requirements as amended by Uruguay Round Agreements Act, Pub.
L. 103-465.

processing of this case, please call the above telephone number. This number is

number and the most convenient time for us to call in case we need more
information. Whether you call or write, please refer to the Letter Serial Number

You should keep this letter as a permanent record. Please notify us if you
modify or discontinue sponsorship of this plan.

                 -- (ii)  If option 1, 2, or 3 is elected, you must elect the
                          same definition of Compensation in Section XIII,
                          Limitations on Allocations.

                 -- (iii) Options 1-6 include lump sum amounts and/or cash
                          bonuses. These amounts are included in compensation 
                          in the year in which paid.

                 -- (iv)  Options 4-9 may not be elected by a plan that uses an
                          integrated allocation formula.

                 -- (v)   This compensation definition is for purposes of

                          9 for nondiscrimination testing requires that the

                          nondiscrimination test.

                another qualified retirement plan in which any Participant
                in this Plan is, was, or could be a participant.

                        [X]  1.  N/A.  The Employer has no defined benefit

                                 may not cause the sum of the Defined Benefit
                                 Plan Fraction and the Defined Contribution
                                 Fraction to exceed 1.0. If the Employer
                                 contributions that would otherwise be
                                 allocated to the Participant's account during
                                 such year would cause the 1.0 limitation to be
                                 exceeded, the allocation will be reduced so
                                 that the sum of the fraction equals 1.0. Any
                                 contributions not allocated because of the
                                 preceding sentence will be allocated to the

                                 allocation formula. If the 1.0 limitation is
                                 exceeded because of an Excess Amount, such
                                 Excess Amount will be reduced in accordance
                                 with Section 4B.4 of the Plan.

                        [ ]  3.  Provide the method under which the Plan
                                 involved will satisfy the 1.0 limitation in a
                                 manner that precludes Employer discretion.

The Employer hereby adopts the Connecticut General Life Insurance Company
Defined Contribution Prototype Profit Sharing/Thrift Plan with 401(k) Feature,
including all elections made in this Non-Standardized Adoption Agreement, and
the Employer agrees to be bound by all the terms of the Plan and by all the
terms of this Adoption Agreement and of the Annuity Contract. The Employer
further agrees that it will furnish promptly all information required by the
Trustee, if applicable, the Plan Administrator and the Insurance Company in
order to carry out their functions. The Employer shall notify the Trustee, if
applicable, the Plan Administrator and the Insurance Company promptly of any
changes in the status of the Employer which might affect the Employer's duties
and responsibilities hereunder.

The elections under this Adoption Agreement may be changed by the Employer from
time to time by a written instrument signed by the Employer, the Plan
Administrator and the Trustee, if applicable, and accepted by the Plan Sponsor.
The Employer consents to the exercise by the Plan Sponsor of the right to amend
the Plan and the Annuity Contract from time to time as it may deem necessary or
advisable.

By signing this Adoption Agreement, the Employer specifically acknowledges that
the Insurance Company has no authority: (1) to answer legal questions and that
all such questions shall be answered by legal counsel for the Employer; and (2)
to make determinations involved in the administration of the Plan and that all
such determinations shall be answered by the Employer's Plan Administrator or
other designated representative.

Upon execution of this Adoption Agreement by the Employer, the Plan shall be
effective with respect to that Employer as of the Effective Date specified
herein, provided the Plan Administrator and the Trustee, if applicable, shall
then or thereafter execute this Adoption Agreement to signify their acceptance
of their duties and responsibilities hereunder and provided further, the Plan
Sponsor will indicate its acceptance of the Employer in accordance with its
usual rules and practices.

The Adopting Employer may not rely on an opinion letter issued by the National
Office of the Internal Revenue Service as evidence that the Plan is qualified
under Internal Revenue Code section 401. In order to obtain reliance with
respect to plan qualification, the Employer must apply to the appropriate key
district office for a determination letter.

Connecticut General Life Insurance Company will inform the Employer of any
amendments made to the Plan or of the discontinuance or abandonment of such
Plan.

CAUTION:  You should very carefully examine the elections you have made in this
Adoption Agreement and discuss them with your legal counsel. Failure to
properly fill out the Adoption Agreement may result in disqualification of your
plan. This Adoption Agreement may only be used in conjunction with Basic Plan
Document Number 03.

(Note:   The Employer, Plan Administrator and Trustee, if applicable, must all
sign below.)

Dear Applicant:

In our opinion, the form of the plan identified above is acceptable under
Section 401 of the Internal Revenue Code for use by employers for the benefit of
their employees. This opinion relates only to the acceptability of the form of
the plan under the Internal Revenue Code. It is not an opinion of the effect of
other Federal or other local statutes.

You must furnish a copy of this letter to each employer who adopts this plan.
You are also required to send a copy of the approved form of the plan, any
approved amendments and related documents to each Key District Director of
Internal Revenue Service in whose jurisdiction there are adopting employers.

Our opinion on the acceptability of the form of the plan is not a ruling or
determination as to whether an employer's plan qualifies under Code section
401(a). Therefore, an employer adopting the form of the plan should apply for a
determination letter by filing an application with the Key District Director of
Internal Revenue Service on Form 5307, Short Form Application for Determination
for Employee Benefit Plan.

Because you submitted this plan for approval after March 31, 1991, the
continued, interim and extended reliance provisions of sections 13 and 17.03 of
Rev. Proc. 89-9, 1989-1 C.B. 780, are not applicable.

Because you submitted this plan on or after July 1, 1994, it does not meet the
requirements for the extension of the remedial amendment period provided by Rev.
Proc. 95-12, 1995-3 I.R.S. 24.

This letter may not be relied upon with respect to whether the plan satisfies
the qualification requirements as amended by Uruguay Round Agreements Act, Pub.
L. 103-465.

If you, the sponsoring organization, have any questions concerning the IRS
processing of this case, please call the above telephone number. This number is
only for use of the sponsoring organization. Individual participants and/or
adopting employers with questions concerning the plan should contact the
sponsoring organization. The plan's adoption agreement must include the
sponsoring organization's address and telephone number for inquiries by 
adopting employers.

If you write to the IRS regarding this plan, please provide your telephone
number and the most convenient time for us to call in case we need more
information. Whether you call or write, please refer to the Letter Serial Number
and File Folder Number shown in the heading of this letter.

You should keep this letter as a permanent record. Please notify us if you
modify or discontinue sponsorship of this plan.

                                   Sincerely yours,



                                   /s/ [ILLEGIBLE]

                   CONNECTICUT GENERAL LIFE INSURANCE COMPANY
                           DEFINED CONTRIBUTION PLAN
                         BASIC PLAN DOCUMENT NUMBER 03

The Plan set forth herein may be adopted by an Employer and accepted by the
Plan Administrator and, if applicable, the Trustee by executing an Adoption
Agreement, which together shall constitute the Employer's Plan, for the
exclusive benefit of its eligible Employees and their Beneficiaries, as fully
as if set forth in said Adoption Agreement; provided, however, no Employer may
adopt this Plan except with the consent of Connecticut General Life Insurance
Company.

                            ARTICLE I - DEFINITIONS

     1.1  ACCRUED BENEFIT. The term Accrued Benefit means the value of the
          Participant's Account on any applicable date.

     1.2  ADDITIONAL MATCHING CONTRIBUTIONS. The term Additional Matching
          Contributions means additional discretionary Matching Contributions
          made to the Plan by the Employer, as authorized by its Board of
          Directors by resolution. Additional Matching Contributions shall be
          treated as Matching Contributions for nondiscrimination testing and
          allocation purposes.

     1.3  ADOPTION AGREEMENT. The term Adoption Agreement means the prescribed
          agreement by which the Employer adopts this Plan, and which sets forth
          the elective provisions of this Plan as specified by the Employer.

     1.4  ALTERNATE PAYEE. The term Alternate Payee means a person, other than
          the Participant, identified under a QDRO to be a recipient of part or
          all of the Participant's benefit under the Plan.

     1.5  ANNUITY. The term Annuity means a series of payments made over a
          specified period of time.

     1.6  ANNUITY CONTRACT. The term Annuity Contract means the group of
          annuity contract form issued by the Insurance Company to fund the
          benefits provided under this Plan, as such contract may be amended
          from time to time in accordance with the terms thereof. The Employer
          will specify and communicate to its Employees the types of investments
          available under this Plan and Annuity Contract.

     1.7  ANNUITY STARTING DATE. The term Annuity Starting Date means the first
          day of the first period for which an amount is paid as an Annuity or
          any other form.

     1.8  BENEFICIARY. The term Beneficiary means the beneficiary or
          beneficiaries entitled to any benefits under a Participant's Account
          hereunder upon the death of a Participant, Beneficiary or Alternate
          Payee pursuant to a QDRO. If any Life Insurance Policy is purchased on
          the life of a Participant hereunder, the Beneficiary under such Policy
          shall be designated separately therein. However, any such Beneficiary
          designation shall be subject to the terms of Section 3C.

          A Participant's Beneficiary shall be his Spouse, if any, unless the
          Participant designates a person or persons other than his Spouse as
          Beneficiary with his Spouse's written consent. A Participant may
          designate a Beneficiary on the form approved by the Plan
          Administrator.


Article I - Definitions               -1-
<PAGE>   10
          If any distribution is made to a Beneficiary in the form of an
          Annuity, and if such Annuity provides for a death benefit, then such
          Beneficiary shall also have a right to designate a beneficiary and to
          change that beneficiary from time to time. As an alternative to
          receiving the benefit in the form of an Annuity, the Beneficiary may
          elect to receive a single cash payment or any other form of payment
          provided by the Employer's election in the Adoption Agreement.

          If no Beneficiary has been designated pursuant to the provisions of
          this Section, or if no Beneficiary survives the Participant and he has
          no surviving Spouse, then the Beneficiary under the Plan shall be the
          deceased Participant's surviving children in equal shares or, if
          there are no surviving children, the Participant's estate. If a
          Beneficiary dies after becoming entitled to receive a distribution
          under the Plan but before distribution is made to him in full, and if
          no other Beneficiary has been designated to receive the balance of
          the distribution in that event, the estate of the deceased
          Beneficiary shall be the Beneficiary for the balance of the
          distribution.

          If the Employer so elects in the Adoption Agreement, an Alternate
          Payee and/or Beneficiary shall be allowed to direct the investment of
          his segregated portion of the Participant's Account, pursuant to
          Section 5A. An individual who is designated as an Alternative Payee
          in a QDRO relating to a Participant's benefits under this Plan shall
          be treated as a Beneficiary hereunder, to the extent provided by such
          order.

     1.9  BOARD OF DIRECTORS. The term Board of Directors means the Employer's
          board of directors or other comparable governing body.

     1.10 CODA. The term CODA means cash or deferred arrangement as described
          in Code section 401(k) and the regulations thereunder.

     1.11 CODE. The term Code means the Internal Revenue Code of 1986, as
          amended from time to time.

     1.12 COMPENSATION. The term Compensation means Compensation as defined
          below. For any Self-Employed Individual covered under the Plan,
          Compensation shall mean Earned Income. Compensation shall include
          only that Compensation which is actually paid to the Participant
          during the applicable Determination Period. Except as provided
          elsewhere in this Plan, the "Determination Period" shall be the
          period elected by the Employer in the Adoption Agreement. If the
          Employer makes no election, the Determination Period shall be the
          Plan Year.

          An Employer may elect in the Adoption Agreement to use one of the
          following definitions of Compensation for purposes of allocating all
          contributions:

          (a)  Wages, Tips and Other Compensation Box on Form W-2. (Information
               required to be reported under Code sections 6041, 6051 and
               6052). Wages within the meaning of 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 sections 6041(d), 6051(a)(3), and 6052.
               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)).



Article I - Definitions               -2-
<PAGE>   11
          (b)  SECTION 3401(a) WAGES. Wages as defined in Code section 3401(a)
               for the purposes of 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)).

          (c)  415 SAFE-HARBOR COMPENSATION.  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 maintaining the Plan to the extent that the amounts are
               includable 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
               Code section 1.62-2(c)), and excluding the following:

               (1)  Employer contributions to a plan of deferred compensation
                    which are not includable in the Employee's gross income for
                    the taxable year in which contributed, or Employer
                    contributions under a simplified employee pension plan to
                    the extent such contributions are deductible by the
                    Employee, 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 excludable from the
                    gross income of the Employee).

          (d)  MODIFIED WAGES, TIPS, AND OTHER COMPENSATION BOX ON FORM W-2.
               Compensation as defined in subsection (a) above, but reduced by
               all of the following items (even if includable in gross income):
               reimbursements or other expense allowances, fringe benefits (cash
               or noncash), moving expenses, deferred compensation, and welfare
               benefits. This definition may not be used by standardized plans
               or plans using a contribution or allocation formula that is
               integrated with Social Security.

          (e)  MODIFIED SECTION 3401(a) WAGES. Compensation as defined in
               subsection (b) above, but reduced by all of the following items
               (even if includable in gross income): reimbursements or other
               expense allowances, fringe benefits (cash or noncash), moving
               expenses, deferred compensation, and welfare benefits. This
               definition may not be used by standardized plans or plans using a
               contribution or allocation formula that is integrated with Social
               Security.

          (f)  MODIFIED 415 SAFE-HARBOR COMPENSATION. Compensation as defined in
               subsection (c) above, but reduced by all of the following items
               (even if


Article I - Definitions                      -3-

<PAGE>   12
               includable in gross income): reimbursements or other expense
               allowances, fringe benefits (cash or noncash), moving expenses,
               deferred compensation, and welfare benefits. This definition may
               not be used by standardized plans or plans using a contribution
               or allocation formula that is integrated with Social Security.

          (g)  REGULAR OR BASE SALARY OR WAGES. Regular or base salary or wages
               (excluding overtime and bonuses) received during the applicable
               period by the Employee from the Employer. This definition may not
               be used by standardized plans or plans using a contribution or
               allocation formula that is integrated with Social Security.

          (h)  REGULAR OR BASE SALARY WAGES PLUS OVERTIME AND/OR BONUSES.
               Regular or base salary or wages, plus either or both overtime
               and/or bonuses, as elected by the Employer in the Adoption
               Agreement, received during the applicable period by the Employee
               from the Employer. This definition may not be used by
               standardized plans or plans using a contribution or allocation
               formula that is integrated with Social Security.

          (i)  A REASONABLE ALTERNATIVE DEFINITION OF COMPENSATION, as that term
               is used in Code section 414(s)(3) and the regulations thereunder,
               provided that the definition does not favor Highly Compensated
               Employees and satisfies the nondiscrimination requirements under
               Code section 414(s). This definition may not be used by
               standardized plans or plans using a contribution or allocation
               formula that is integrated with Social Security.

          Notwithstanding the above, if elected by the Employer in the Adoption
          Agreement, Compensation shall include any amount which is contributed
          by the Employer pursuant to a salary reduction agreement and which is
          not includable in the gross income of the Employee under Code sections
          125, 402(e)(3), 402(h)(1)(B) or 403(b).

          For years beginning on or after January 1, 1989, and before January 1,
          1994, the annual Compensation of each Participant taken into account
          for determining all benefits provided under the Plan for any Plan Year
          shall not exceed $200,000. This limitation shall be adjusted by the
          Secretary at the same time and in the same manner as under Code
          section 415(d) (unless a lesser amount is elected by the Employer in
          the Adoption Agreement), except that the dollar increase in effect on
          January 1 of any calendar year is effective for Plan Years beginning
          in such calendar year and the first adjustment to the $200,000
          limitation is effective on January 1, 1990.

          For Plans Years beginning on or after January 1, 1994, the annual
          Compensation of each Participant taken into account for determining
          all benefits provided under the Plan for any Plan Year shall not
          exceed $150,000, as adjusted for increases in the cost-of-living in
          accordance with Code section 401(a)(17)(B). The cost-of-living
          adjustment in effect for a calendar year applies to any Determination
          Period beginning in such calendar year.

          If a Determination Period consists of fewer than 12 calendar months,
          then the annual compensation limit is an amount equal to the annual
          compensation limit for the calendar year in which the compensation
          period begins, multiplied by the ratio obtained by dividing the number
          of full months in the period by 12.

          In determining the Compensation of a Participant for purposes of this
          limit, the rules of Code section 414(q)(6) shall apply, except in
          applying such rules, the 


Article I - Definitions                 -4-

<PAGE>   13
           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 close of the year.  If, as a result of the application
           of such rules, the adjusted annual Compensation limit is exceeded,
           then (except for purposes of determining the portion of Compensation
           up to the integration level if this Plan uses a contribution or
           allocation formula that is integrated with Social Security), the
           limit 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 limit.

           If Compensation for any prior Determination Period is taken into
           account in determining an Employee's contributions or benefits for
           the current year, the Compensation for such prior Determination
           Period is subject to the applicable annual compensation limit in
           effect for that prior period.  For this purpose, in determining
           allocations in Plan Years beginning on or before January 1, 1989, the
           annual compensation limit in effect for Determination Periods before
           that date is $200,000.  In addition, in determining allocations in
           Plan Years beginning on or after January 1, 1994, the annual
           compensation limit in effect for Determination Periods beginning
           before that date is $150,000.

     1.13  CONSIDERED NET PROFITS.  The term Considered Net Profits means the
           entire amount of the accumulated or current operating profits
           (excluding capital gains from the sale or involuntary conversion of
           capital or business assets) of the Employer after all expenses and
           charges other than (1) the Employer contribution to this and any
           other qualified plan, and (2) federal, state or local taxes based
           upon or measured by income, as determined by the Employer, either on
           an estimated basis or a final basis, in accordance with the generally
           accepted accounting principles used by the Employer. When, for any
           Plan Year, the amount of Considered Net Profits has been determined
           by the Employer, and the Employer contribution made on the basis of
           such determination, such determination and contribution shall be
           final and conclusive and shall not be subject to change because of
           any adjustments in income or expense which may be required by the
           Internal Revenue Service or otherwise.  Such determination and
           contribution shall not be open to question by any Participant either
           before or after the Employer contribution has been made.

           In the case of an Employer that is a non-profit entity, the term
           Considered Net Profits means the entire amount of the accumulated or
           current operating surplus (excluding capital gains from the sale or
           involuntary conversion of capital or business assets) of the Employer
           after all expenses and charges other than (1) the contribution made
           by the Employer to the Plan, and (2) federal, state or local taxes
           based upon or measured by income, in accordance with the generally
           accepted accounting principles used by the Employer.

     1.14  CONTRIBUTION PERIOD.  The term Contribution Period means that regular
           period, specified by the Employer in its Adoption Agreement, for
           which the Employer shall make Employer contributions, if any, and
           that regular period specified by the Employer in its Adoption
           Agreement, for which Participants may make Employee Contributions, if
           any, and Elective Deferral Contributions, if any.  The first
           Contribution Period may be an irregular period, not longer than one
           month, commencing not prior to the Effective Date.  However, the
           first Contribution Period for Elective Deferral Contributions may not
           commence before the later of the Plan's Effective Date or adoption
           date.

<PAGE>   14
     1.15 DAVIS-BACON ACT. The term Davis-Bacon Act means the Davis-Bacon Act
          (40 U.S.C. section 276(a) et seq., as amended from time to time),
          which guarantees minimum wages to laborers and mechanics employed on
          Federal government contracts for the construction, alteration, or
          repair of public buildings or works. The minimums are the amounts
          found by the Secretary of Labor to be prevailing for similar workers
          in the area in which the work is to be done.

          The term "wages" as used in the Davis-Bacon Act includes, in addition
          to the basic hourly rate of pay, contributions irrevocably made to
          trustees for pension benefits for laborers and mechanics employed on
          Federal government contracts and the cost of other fringe benefits.
          However, overtime pay is to be computed only on the basis of the
          basic hourly rate of pay.

     1.16 DISABILITY. The term Disability means a Participant's incapacity to
          engage in any substantial gainful activity because of a medically
          determinable physical or mental impairment which can be expected to
          result in death, or which has lasted or can be expected to last for a
          continuous period of not less than 12 months. The performance and
          degree of such impairment shall be supported by medical evidence. All
          Participants in similar circumstances shall be treated alike.

          If elected by the Employer in the Adoption Agreement, nonforfeitable
          contributions will be made to the Plan on behalf of each disabled
          Participant who is not a Highly Compensated Employee (within the
          meaning of Section 1.29 of the Plan).

     1.17 DISABILITY RETIREMENT DATE. The term Disability Retirement Date means
          the first day of the month after the Plan Administrator has
          determined that a Participant's incapacity is a Disability. A
          Participant who retires from the Service of the Employer as of his
          Disability Retirement Date shall have a Vesting Percentage of 100%
          and shall be entitled to receive a distribution of the entire value
          of his Participant's Account and any Life Insurance Policies, or the
          values thereof, as of his Disability Retirement Date, subject to the
          provisions of Section 3A and Section 3C.

     1.18 EARLY RETIREMENT DATE. If the Employer has specified in its Adoption
          Agreement that Early Retirement is permitted, then the term Early
          Retirement Date means the first day of the month coinciding with or
          next following the date a Participant is separated from Service with
          the Employer for any reason other than death or Disability, provided
          that on such date the Participant has attained the conditions
          specified by the Employer in its Adoption Agreement and has not
          attained his Normal Retirement Age. A Participant who retires from
          the Service of the Employer on his Early Retirement Date shall have a
          Vesting Percentage of 100% and shall be entitled to receive a
          distribution of the entire value of his Participant's Account and any
          Life Insurance Policies, or the values thereof, as of his Early
          Retirement Date, subject to the provisions of Section 3A and Section
          3C.

          If a Participant separates from Service before satisfying the age
          requirements for Early Retirement, but has satisfied the Service
          requirement, the Participant shall be 100% vested as of his
          Termination of Employment date, but he will not be eligible for a
          distribution of the entire value of his Participant's Account until
          satisfying such age requirement.

     1.19 EARNED INCOME. The term Earned Income means the net earnings from
          self-employment in the trade or business with respect to which the
          Plan is established, and for which the personal services of the
          individual are a material


Article I - Definitions               -6-
<PAGE>   15
          income-producing factor. Net earnings will be determined without
          regard to items not included in gross income and the deductions
          allocable to such items. Net earnings are reduced by contributions
          made by the Employer to a qualified plan to the extent deductible
          under Code section 404.

          Net earnings shall be determined with regard to the deductions allowed
          to the taxpayer by Code section 164(f) for taxable years beginning
          after December 31, 1989.

     1.20 EFFECTIVE DATE. The term Effective Date means the date specified by
          the Employer in its Adoption Agreement as the Effective Date of the
          Plan.

     1.21 ELECTIVE DEFERRAL CONTRIBUTIONS. The term Elective Deferral
          Contributions means contributions made by the Employer to the Plan at
          the election of the Participant, in lieu of cash compensation, and
          shall include contributions made pursuant to a Salary Deferral
          Agreement or other deferral mechanism.

          With respect to any taxable year, a Participant's elective deferral is
          the sum of all Employer contributions made on behalf of such
          Participant pursuant to an election to defer under any CODA, any
          simplified employee pension cash or deferred arrangement as described
          in section 402(h)(1)(B), any eligible deferred compensation plan as
          described in section 457, any plan described in section 501(c)(18),
          and any Employer contributions made on the behalf of a Participant for
          the purchase of an annuity contract under section 403(b) pursuant to a
          salary reduction agreement.

          Elective Deferral Contributions shall not include those contributions
          properly distributed as Excess Annual Additions, as defined in Section
          4C.1(b).

     1.22 EMPLOYEE. The term Employee means any employee of the Employer
          maintaining the Plan or any other employer required to be aggregated
          with such Employer under Code sections 414(b), (c), (m), or (o).

          The term Employee also includes any Leased Employee deemed to be an
          Employee of the Employer in accordance with code sections 414(n) or
          (o).

     1.23 EMPLOYEE CONTRIBUTIONS. The term Employee Contributions means
          contributions to this Plan or any other plan, that are designated or
          treated at the time of contribution as after-tax contributions made by
          the Employee and are allocated to a separate account to which
          attributable earnings and losses are allocated. Such term includes
          Required Employee Contributions, Voluntary Employee Contributions,
          Prior Required Employee Contributions, and Prior Voluntary Employee
          Contributions.

     1.24 EMPLOYER. The term Employer means the employer that adopts this Plan.
          In the case of a group of Employers that constitutes a controlled
          group of corporations (as defined in Code section 414(b)) or that
          constitutes trades or businesses (whether or not incorporated) that
          are under common control (as defined in section 414(c)) or that
          constitutes an affiliated service group (as defined in section
          414(m)), Service with all such employers shall be considered Service
          with the Employer for purposes of eligibility and vesting. The term
          Employer shall also mean any Adopting Employer as defined in Section
          6E.2.


Article I - Definitions               -7-
<PAGE>   16
          A state or local government or political subdivision thereof, or any
          agency or instrumentality thereof, or any organization exempt from tax
          under Subtitle A of the code, may not elect a 401(k) option (CODA) in 
          the Adoption Agreement.

     1.25 ENTRY DATE. The term Entry Date means either the Effective Date or
          each applicable date thereafter as specified by the Employer in its
          Adoption Agreement, when an Employee who has fulfilled the eligibility
          requirements commences participation in the Plan. 

          If an Employee is not in the active Service of the Employer as of his
          initial Entry Date, his subsequent Entry Date shall be the date he
          returns to the active Service of the Employer, provided he still meets
          the eligibility requirements.  If an Employee does not enroll as a
          Participant as of his initial Entry Date, his subsequent Entry Date
          shall be the applicable Entry Date as specified by the Employer in the
          Adoption Agreement when the Employee actually enrolls as a
          Participant.

     1.26 ERISA. The term ERISA means the Employee Retirement Income Security
          Act of 1974 (PL93-406) as it may be amended from time to time, and
          any regulations issued pursuant thereto as such Act and such
          regulations affect this Plan and Trust.

     1.27 FIDUCIARY.  The term Fiduciary means any or all of the following, as
          applicable:

          (a)  Any Person who exercises any discretionary authority or control
               respecting the management of the Plan or its assets;

          (b)  Any Person who renders investment advice for a fee or other
               compensation, direct or indirect, respecting any monies or other
               property of the Plan or has authority or responsibility to do so;

          (c)  Any Person who has discretionary authority or responsibility in
               the administration of the Plan;

          (d)  Any Person who has been designated by a Named Fiduciary pursuant
               to authority granted by the Plan, who acts to carry out a
               fiduciary responsibility, subject to any exceptions granted
               directly or indirectly by ERISA.


     1.28 FORFEITURE.  The term Forfeiture means the amount, if any, by which
          the value of a Participant's Account exceeds his Vested Interest upon
          the occurrence of an immediate Break-in-Service, a 1-Year
          Break-in-Service or 5 consecutive 1-Year Breaks-in-Service, as
          elected by the Employer in its Adoption Agreement pursuant to Section
          3D.5, following such Participant's Termination of Employment.

     1.29 HIGHLY COMPENSATED EMPLOYEE. The term Highly Compensated Employee
          includes both Highly Compensated Active Employees and Highly
          Compensated Former Employees.

          As elected by the Employer in the Adoption Agreement, the method to
          determine Highly Compensated Employees shall be:

          (A)  TRADITIONAL METHOD: A "Highly Compensated Active Employee"
               includes any Employee who performs service for the Employer
               during the Determination Year and who, during the Look-Back 
               Year;

               (1)  Received Compensation from the Employer in excess of
                    $75,000 (as adjusted pursuant to Code section 415(d)); or



                                      -8-
Article I - Definitions
<PAGE>   17
               (2)  Received Compensation from the Employer in excess of $50,000
                    (as adjusted pursuant to Code section 415 (d)) and was a
                    member of the top-paid group for such year; or

               (3)  Was an officer of the Employer and received Compensation
                    during such year that is greater than 50 percent of the
                    dollar limitation in effect under Code section 415(b)(1)(A).

               The term Highly Compensated Employee also includes: (1) Employees
               who are described in the preceding sentence if the term
               "Determination Year" is substituted for the term "Look-Back Year"
               and who are one of the 100 employees who received the most
               Compensation from the Employer during the Determination Year; and
               (2) Employees who are 5-percent owners at any time during the
               Look-Back Year or Determination Year.

               If no officer has satisfied the Compensation requirement of (3)
               above during either a Determination Year or Look-Back Year, the
               highest paid officer for such year shall be treated as a Highly
               Compensated Employee.

               For the purpose, the Determination Year shall be the Plan Year.
               The Look-Back Year shall be the period elected by the Employer in
               the Adoption Agreement.

               A "Highly Compensated Former Employee" includes any Employee who
               separated from Service (or was deemed to have separated) prior to
               the Determination Year, performs no service for the Employer
               during the Determination Year, and was a highly compensated
               active employee for either the separation year or any
               Determination Year ending on or after the Employee's 55th
               birthday.

               If an Employee is, during a Determination Year or Look-Back Year,
               a family member of either a 5-percent owner who is an active or
               former Employee or a Highly Compensated Employee who is one of
               the 10 most Highly Compensated Employees ranked on the basis of
               Compensation paid by the Employer during such year (a "Top 10
               Highly Compensated Employee"), then the family member and the
               5-percent owner or Top 10 Highly Compensated Employee shall be
               aggregated.  In such case, the family member and 5-percent owner
               or Top 10 Highly Compensated Employee shall be treated as a
               single Employee receiving Compensation and Plan contributions or
               benefits equal to the sum of such Compensation and contributions
               or benefits of the family member and 5-percent owner or Top 10
               Highly Compensated Employee.  For purposes of this Section, the
               term "family member" includes the Spouse, lineal ascendants and
               descendants of the Employee or former Employee and the spouses of
               such lineal ascendants and descendants.

               The determination of who is a Highly Compensated Employee,
               including the determinations of the number and identify of the
               Employees in the top-paid group, the top 100 Employees, the
               number of Employees treated as officers and the Compensation that
               is considered, will be made in accordance with Code section
               414(q) and the regulations thereunder.

               For purposes of this definition, Compensation shall mean
               compensation as  defined in Code section 415(c)(3) except that
               elective or salary reduction contributions to a cafeteria plan,
               CODA or tax-sheltered annuity shall be included in Compensation.

          (b)  SIMPLIFIED METHOD FOR EMPLOYERS IN MORE THAN ONE GEOGRAPHIC AREA:
               If elected by the Employer in the Adoption Agreement, the
               Traditional Method above will be modified by substituting $50,000
               for $75,000 in (1) and by disregarding (2). This simplified
               definition of Highly Compensated Employee will apply to Employers
               that maintain significant business activities (and employ
               Employees) in at least two significant, separate geographic
               areas.

          (c)  ALTERNATIVE SIMPLIFIED METHOD: If elected by the Employer in the
               Adoption Agreement, Highly Compensated Employees shall be
               determined as follows: A Highly Compensated Active Employee
               includes any Employee who performs service for the Employer
               during the Determination Year and who:

               (1)  Is a 5-percent owner; or

               (2)  Received Compensation from the Employer in excess of $75,000
                    (as adjusted pursuant to Code section 415(d)); or

               (3)  Received Compensation from the Employer in excess of $50,000
                    (as adjusted pursuant to Code section 415(d)) and was a
                    member of the top-paid group for such year; or

               (4)  Was an officer of the Employer and received Compensation
                    during such year that is greater than 50 percent of the
                    dollar limitation in effect under Code section 415(b)(1)(A).

               Under this simplified definition, the look-back provisions of
               Code section 414(q) do not apply.

          (d)  ALTERNATIVE SIMPLIFIED METHOD WITH SNAPSHOT: If the Alternative
               Simplified Method of determining Highly Compensated Employees is
               selected by the Employer, the Employer may elect in the Adoption
               Agreement to substantiate that the Plan complies with the
               nondiscrimination requirements on the basis of the Employer's
               work force on a single day during the Plan Year, provided that
               day is reasonably representative of the Employer's work force and
               the Plan's coverage throughout the Plan Year. The day elected by
               the Employer and indicated on the Adoption Agreement shall be the
               "Snapshot Day."

               To apply the Alternative Simplified Method on a snapshot basis:

               (1)  The Employer determines who is a Highly Compensated Employee
                    on the basis of the data as of the Snapshot Day, except as
                    provided in (3) below.

     1.72 TRUE-UP CONTRIBUTIONS. The term True-up Contributions means
          Additional Matching Contributions made to the Plan by the Employer so
          that total Matching Contributions for each Participant are calculated
          on an annual basis rather than on the basis selected by the Employer
          in the Adoption Agreement.

     1.73 TRUST. The term Trust means the Trust Agreement if the Employer
          specifies in the Adoption Agreement that the Plan is Trusteed. The
          Trust Agreement is entered into by the Employer, the Plan
          Administrator and the Trustee by completing and signing the Adoption
          Agreement, which Trust Agreement forms a part of, and implements the
          provisions of the Plan as it applies to the Employer. If the Employer
          specifies in the Adoption Agreement that the Plan is Non-Trusteed,
          then the terms and provisions of this Plan relating to the Trust
          shall be of no force and effect.

     1.74 TRUSTEE. The term Trustee means the trustee(s) designated by the
          Employer in its Adoption Agreement, if applicable, and any
          successor(s) thereto.

     1.75 VESTED INTEREST. The term Vested Interest means the nonforfeitable
          right to an immediate or deferred benefit on any date in the amount
          which is equal to the sum of (a), (b) and (c) below:

          (a)  The value on that date of that portion of the Participant's
               Account that is attributable to and derived from Employee
               Contributions, if any;

          (b)  The value on that date of the portion of the Participant's
               Account attributable to Elective Deferral Contributions, if any;
               Qualified Nonelective Contributions, if any; QVEC Contributions,
               if any; Rollover Contributions, if any; and Qualified Matching
               Contributions, if any;

          (c)  The value on that date of that portion of the Participant's
               Account that is attributable to and derived from contributions
               made by the Employer (and Forfeitures, if any), multiplied by his
               Vesting Percentage determined on the date applicable.


Article I - Definitions                -17-
<PAGE>   26
          Employer contributions described in subsection (c), plus the earnings
          thereon, shall be, at any relevant time, a part of the Participant's
          Vested Interest equal to an amount ("X") determined by the following
          formula:

          X = P(AB + D) - D

          For purposes of applying this formula:

          P  = The Participant's Vesting Percentage at the relevant time.

          AB = The account balance attributable to such contributions, plus
               the earnings thereon, at the relevant time.

          D  = The amount of any distribution.

     1.76 VESTING PERCENTAGE. The term Vesting Percentage means the
          Participant's nonforfeitable interest in Money Purchase Pension
          Contributions, Matching Contributions, Nonelective Contributions, or
          Prior Employer Contributions credited to his Participant's Account,
          plus any income and minus any loss thereon. The Vesting Percentage
          for each such Employer contribution is computed in accordance with
          one of the schedules listed below, based on Years of Service with the
          Employer, as specified by the Employer in its Adoption Agreement:

          (a)  100% full and immediate;

          (b)  100% after 3 Years of Service;

          (c)  20% per Year of Service, 100% at 5 Years of Service;

          (d)  20% after 3 Years of Service, 20% per Year of Service
               thereafter, 100% at 7 Years of Service;

          (e)  20% after 2 Years of Service, 20% per Year of Service thereafter,
               100% at 6 Years of Service;          

          (f)  100% after 5 Years of Service;

          (g)  25% after 1 Year of Service; 100% after 4 Years of Service;

          (h)  Other.

          However, if a Participant dies prior to attaining his Normal
          Retirement Age, his Vesting Percentage shall be 100%.

     1.77 VOLUNTARY EMPLOYEE CONTRIBUTIONS. The term Voluntary Employee
          Contributions means post-tax contributions made voluntarily by an
          Employee.

                                  2A. SERVICE

     2A.1 SERVICE. The term Service means active employment with the Employer
          as an Employee.

     2A.2 ABSENCE FROM EMPLOYMENT. Absence from employment on account of a leave
          of absence authorized by the Employer pursuant to the Employer's
          established leave policy will be counted as employment with the
          Employer provided that such leave of absence is of not more than two
          years' duration. Absence from employment on account of active duty
          with the Armed Forces of the United States will be counted as
          employment with the Employer. If the Employee does not return to
          active employment with the Employer, his Service will be deemed to
          have ceased on the date the Plan Administrator receives notice that
          the Employee will not return. The Employer's leave policy shall be
          applied in a uniform and nondiscriminatory manner to all Participants
          under similar circumstances.

          For purposes of determining an Employee's eligibility and vesting
          status for periods while the Employee is absent from work for reasons
          covered under the Family and Medical Leave Act, Service will be
          credited in accordance with and to the extent required by the
          provisions of the Family and Medical Leave Act.

     If the Employer has elected in the Adoption Agreement to determine Service
     based upon 1,000 Hours, then the following Sections 2A.3 through 2A.8 shall
     apply.

     2A.3 HOUR OF SERVICE. The term Hour of Service means:

          (a)  Each hour for which an Employee is directly or indirectly paid,
               or entitled to payment, by the Employer for the performance of
               duties. These hours shall be credited to the Employee for the
               Computation Period or Periods, as defined in Section 2A.5, in
               which the duties were 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 will
               be credited under this paragraph for a single Computation Period
               (whether or not the period occurs in a single Computation
               Period). Hours under this paragraph will be calculated and
               credited pursuant to section 2530.200b-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, has been either awarded or agreed to by the Employer.
               The same Hours of Service will not be credited under subsection
               (a) or subsection (b), as the case may be, and under this
               subsection (c). These hours shall be credited to the Employee for
               the Computation Period or periods to which the award or agreement
               pertains rather than the Computation Period in which the award,
               agreement or payment is made; and Hours of Service will be
               credited for employment with other members of an affiliated
               service group (under Code section 414(m)), a controlled group of
               corporations (under Code section 414(b)), or a group of trades or
               businesses under common


Article II - General Provisions       -19-
<PAGE>   28
               control (under 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).

          Hours of Service will also be credited for any individual considered
          an Employee for purposes of this Plan under Code sections 414(n) or
          414(o).

          Solely for purposes of determining whether a 1-Year Break-in-Service,
          as defined in Section 2A.4, 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, eight (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 (1) by reason of the
          pregnancy of the individual, (2) by reason of a birth of a child of
          the individual, (3) by reason of the placement of a child with the
          individual in connection with the adoption of such child by such
          individual, or (4) 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 (1) in the
          Computation Period in which the absence begins if the crediting is
          necessary to prevent a Break-in-Service in that period, or (2) in all
          other cases, in the following Computation Period.

          Service shall be determined on the basis of the method selected in the
          Adoption Agreement.

     2A.4 1-YEAR BREAK-IN-SERVICE. The term 1-Year Break-in-Service means any
          Computation Period during which an Employee fails to complete more
          than 500 Hours of Service.

     2A.5 YEAR(S) OF SERVICE. The term Year(s) of Service means a
          12-consecutive month period ("Computation Period") during which an
          Employee has completed at least 1,000 Hours of Service.

          (a)  Eligibility Computation Period. For purposes of determining
               Years of Service and Breaks-in-Service for eligibility, the
               12-consecutive month period shall begin with the date on which 
               the Employee first performs an Hour of Service for the Employer
               and, where additional periods are necessary, succeeding 
               anniversaries of his employment commencement date. The employment
               commencement date is the date on which the Employee first 
               performs an Hour of Service for the Employer maintaining the 
               Plan.

          (b)  Vesting Computation Period. As elected by the Employer in the
               Adoption Agreement, for computing Years of Service and
               Breaks-in-Service for vesting, the 12-consecutive month period:

               (1)  Shall be the Plan Year; or

               (2)  Shall begin with the date on which the Employee first
                    performs an Hour of Service for the Employer and, where 
                    additional periods are necessary, succeeding anniversaries
                    of that date.

               However, active participation as of the last day of the Plan
               Year is not required in order for a Participant to be credited 
               with a Year of Service for vesting purposes.



Article II - General Provisions               -20-
<PAGE>   29
          (c)  Contribution Computation Period. If the Employer specifies an
               annual Contribution Period in its Adoption Agreement for the
               purpose of determining a Participant's eligibility to receive a
               contribution, the 12-consecutive month period shall be any Plan
               Year during which the Participant is credited with at least 1,000
               Hours of Service. However, when an Employee first becomes a
               Participant or resumes active participation in the Plan following
               a 1-Year Break-in-Service on a date other than the first day of
               the Plan Year, all Hours of Service credited to the Participant
               during that Plan Year, including those Hours credited prior to
               the date the Employee enrolls (or reenrolls) as a Participant in
               the Plan shall be counted. Furthermore, the Employer may require
               in its Adoption Agreement that a Participant be a Participant as
               of the last day of the Plan Year in order to be eligible to
               receive a contribution for a Plan Year.

          (d)  If in its Adoption Agreement the Employer permits Early
               Retirement, the 12-consecutive month period for determining Early
               Retirement shall be the Plan Year.  However, active participation
               as of the last day of the Plan Year is not required in order
               for a Participant to be credited with a Year of Service.

          Service with a predecessor organization of the Employer shall be
          treated as Service with the Employer for the purposes of subsection
          (a), (b) and (d) above in any case in which the Employer maintains
          the plan of such predecessor organization. In addition, if elected by
          the Employer in the Adoption Agreement, service with a predecessor
          organization of the Employer shall be treated as Service with the
          Employer, even if the Employer does not maintain the plan of such
          predecessor organization.

          If elected in the Adoption Agreement, service with a subsidiary or
          affiliate of the Employer that is not related to the Employer under
          the provisions of Code sections 414 (b), (c) or (m) shall be treated
          as Service with the Employer for purposes of (a), (b) and (d) above.

     2A.6 DETERMINING VESTING PERCENTAGE. Vesting credit shall be given for
          each Year of Service except those periods specifically excluded in
          the Adoption Agreement.

          If a Participant completes less than 1,000 Hours of Service during a
          Plan Year while remaining in the service of the Employer, his Vesting
          Percentage shall not be increased for such Plan Year. However, at
          such time as the Participant again completes at least 1,000 Hours of
          Service in any subsequent Plan Year, his Vesting Percentage shall
          then take into account all Years of Service with the Employer except
          those specifically excluded in the Adoption Agreement.

          If an individual who ceases to be an Employee and is subsequently
          rehired as an Employee enrolls (or reenrolls) in the Plan, upon his
          participation (or reparticipation) his Vesting Percentage shall then
          take into account all Years of Service except those specifically
          excluded in the Adoption Agreement.

          In the case of a Participant who has 5 consecutive 1-Year
          Breaks-in-Service, all Years of Service after such Breaks-in-Service
          will be disregarded for the purpose of vesting the Employer-derived
          account balance that accrued before such breaks. However, both
          pre-break and post-break Service will count for the purpose of
          vesting the Employer-derived account balance that accrues after such
          Breaks-in-Service. Both accounts will share in the earnings and
          losses of the fund.


Article II - General Provisions             -21-
<PAGE>   30
          In the case of a Participant who does not have 5-consecutive 1-Year
          Breaks-in-Service, both the pre-break and post-break Service will
          count in vesting both the pre-break and post-break Employer-derived
          account balance.

     2A.7 EXCLUDED YEARS OF SERVICE FOR VESTING. In determining the Vesting
          Percentage of an Employee, all Years of Service with the Employer(s)
          maintaining the Plan shall be taken into account, except that the
          following periods may be excluded, as specified by the Employer in its
          Adoption Agreement:

          (a)  Years of Service prior to the time a Participant attained age 18;

          (b)  Years of Service during which the Employer did not maintain the
               Plan or a predecessor plan;

          (c)  Years of Service during a period for which the Employee made no
               Required Employee Contributions;

          (d)  Years of Service prior to any 1-Year Break-in-Service, until the
               Employee completes one Year of Service following such 1-Year
               Break-in-Service.
     
          (e)  In the case of any Employee who has no Vested Interest in
               Employer contributions, Years of Service before any period of
               consecutive 1-Year Breaks-in-Service if the number of such
               consecutive 1-Year Breaks-in-Service equals or exceeds the
               greater of (i)5, or (ii) the total number of Years of Service
               before such break.

          For the purposes of this Section, a predecessor plan shall mean a plan
          of the Employer that was terminated within five years preceding or
          following the Effective date of this Plan.

     2A.8 CHANGE IN PLAN YEARS. If the Plan Year is changed, the following
          special rules shall apply.

          (a)  Vesting Computation Periods. If the Vesting Computation Period is
               the Plan Year, Years of Service and 1-Year Breaks-in-Service
               shall be measured over two overlapping 12-consecutive month
               periods. The first such period shall begin on the first day of
               the last old Plan Year and the second such period shall begin on
               the first day of the first new Plan Year, thereby creating an
               overlap. All Hours of Service performed during the overlap period
               must be counted in both Vesting Computation Periods. A
               Participant who completes at least 1,000 Hours of Service during
               each such period shall be credited with two Years of Service for
               Vesting.

          (b)  Contribution Computation Periods. To determine a Participant's
               eligibility to receive a contribution for a short Plan Year, the
               1,000 Hours of Service requirement shall be prorated by
               multiplying 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.



Article II - General Provisions       -22-




<PAGE>   31
If the Employer has elected in the Adoption Agreement to determine Service
based upon Elapsed Time, then the following Sections 2A.9 and 2A.10 shall apply.

2A.9 ELAPSED TIME. If the Employer has selected an eligibility requirement in
     the Adoption Agreement that is or includes a fractional Year(s) of Service
     requirement, the provisions of this Section shall apply.

     (a)  For purposes of determining an Employee's initial or continued
          eligibility to participate in the Plan, or the Participant's Vested
          Interest in Employer contributions, an Employee will receive credit
          for the aggregate of all time period(s) commencing with the Employee's
          first day of employment or reemployment and ending on the date a
          Break-in-Service (as defined in this Section) begins. The first day of
          employment or reemployment is the first day the Employee performs an
          Hour of Service. An Employee will also receive credit for any Period
          of Severance of less than 12-consecutive months. Fractional periods of
          a year will be expressed in terms of days.

     (b)  For purposes of this Section, "Hour of Service" shall mean each hour
          for which an Employee is paid or entitled to payment for the
          performance of duties for the Employer.

     (c)  For purposes of this Section, a "Break-in-Service" is a Period of
          Severance of at least 12 consecutive months.

     (d)  A "Period of Severance" is a continuous period of time during which
          the Employee is not employed by the Employer. Such period begins on
          the date the Employee retires, quits or is discharged, or if earlier,
          the 12-month anniversary of the date on which the Employee was
          otherwise first absent from Service.

     (e)  In the case of an individual who is absent from work for maternity or
          paternity reasons, the 12-consecutive month period beginning on the
          first anniversary of the first day of such absence shall not
          constitute a Break-in-Service. For purposes of this paragraph, an
          absence from work for maternity or paternity reasons means an absence
          (1) by reason of the pregnancy of the individual, (2) by reason of the
          birth of a child of the individual, (3) by reason of the placement of
          a child with the individual in connection with the adoption of such
          child by such individual, or (4) for purposes of caring for such child
          for a period beginning immediately following such birth or placement.

          Each Employee will share in Employer contributions for the period
          beginning on the date the Employee commences participation under the
          Plan and ending on the date on which such Employee severs employment
          with the Employer or is no longer a member of an eligible class of
          Employees.

     (f)  If the Employer is a member of an affiliated service group (under Code
          section 414(m)), a controlled group of corporations (under Code

          will be created for any employment for any period of time for any

     2A.10  EXCLUDED PERIODS OF SERVICE FOR VESTING. In determining the Vesting
            Percentage of an Employee, all Periods of Service with the
            Employer(s) maintaining the Plan shall be taken into account, except
            that the following periods may be excluded, as specified by the
            Employer in its Adoption Agreement:

            (a)  Periods of Service prior to the time a Participant attained age

            (d)  Periods of Service prior to any one-year Period of Severance,
                 until the Employee completes a one-year period of Service
                 following such Period of Severance;

            (e)  In the case of an Employee who has no Vested Interest in

                 total number of one-year Periods of Service before such Period
                 of Severance.

            plan of the Employer that was terminated within five years preceding
            or following the Effective Date of this Plan.

                 2.B. ELIGIBILITY, ENROLLMENT AND PARTICIPATION

     2B.1   ELIGIBILITY. Each Employee shall be eligible to participate in the
            Plan and receive an appropriate allocation of Employer contributions
            as of the Entry Date following the day he meets the following
            requirements, if any, specified by the Employer in its Adoption
            Agreement, relating to:

            (a)  Required service;

            (b)  Minimum attained age;

            (c)  Job class requirements.

            In addition to the eligibility conditions stated above, the Employer
            may specify in the Adoption Agreement certain groups of Employees
            who are not eligible to participate in the Plan.

            Notwithstanding the foregoing, if the Employer's Plan as set forth
            herein replaces or amends a preceding plan, then those Employees
            participating under the Plan as written prior to such replacement or
            amendment shall be eligible to be Participants hereunder without
            regard to length of Service or minimum attained age otherwise
            required herein.

     2B.2   ENROLLMENT. Each eligible Employee may enroll as of his Entry Date

     2B.3 REEMPLOYED PARTICIPANT. In the case of an individual who ceases to be
          an Employee and is subsequently rehired as an Employee, the following
          provisions shall apply in determining eligibility to again participate
          in the Plan:

          (a)  If the Employee had met the eligibility requirements as
               specified in Section 2B.1, such Employee will become a
               Participant in the Plan in accordance with Section 2B.2 as of the
               date he is reemployed as an Employee.

          (b)  If the Employee had not formerly met the eligibility
               requirements specified in Section 2B.1, such Employee will become
               a Participant in the Plan after meeting the requirements of
               Section 2B.1 in accordance with Section 2B.2.

     2B.4 ELIGIBLE CLASS. If a Participant become ineligible to participate
          because he is no longer a member of an eligible class of Employees,
          such Employee shall participate immediately upon his return to an
          eligible class of Employees. If such Participant incurs a
          Break-in-Service, eligibility will be determined under the
          Break-in-Service rules of the Plan.          

          If 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 been in the eligible class. If such Participant
          incurs a Break-in-Service, eligibility will be determined under the
          Break-in-Service rules of the Plan.

     2B.5 WAIVER OF PARTICIPATION. Notwithstanding any provision of the Plan to
          the contrary, if Required Employee Contributions are elected by the
          Employer in the Adoption Agreement, any Employee in accordance with
          the rules of the Plan may decline to become a Participant or cease to
          be a Participant by filing a written waiver of participation with the
          Plan Administrator in the manner prescribed. Such waiver must be filed
          prior to the date such Employee is eligible to become a Participant,
          or in the case of a current Participant, in the last month of the Plan
          Year immediately preceding the Plan Year for which he wishes to cease
          being a Participant.

          Any Employee who files such a waiver shall not become a Participant,
          or if a current Participant, shall elect to cease to be such as of the
          first day of the succeeding Plan Year; and such Employee shall not
          receive any additional Compensation or other sums by reason of his
          waiver of participation.

          Any such waiver may be rescinded by an Employee who is not a Partner
          effective on the first day of the first Plan Year following one or
          more Plan Years commencing after the filing of such waiver in which
          he was not a Participant, in which event he shall become a
          Participant, or again become a Participant, as the case may be,
          effective as of such date. A Partner may make a one-time irrevocable
          waiver of participation upon the later of his commencement of
          employment with the Employer or the date he is first eligible to
          participate in the Plan.

          No Employee who is eligible to participate in a standardized plan may
          waive participation or voluntarily reduce his or her Compensation for
          purposes of this Plan.

     2B.6 TRADES OR BUSINESSES CONTROLLED BY 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 any plans
          established for other trades or businesses

     Article II - General Provisions  -25-
                                     
          
<PAGE>   34
          must, when looked 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 those 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 he does not control 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 he does control must be as favorable as those provided for him
          under the most favorable plan of the trade or business which he does
          not control.

          For purposes of the preceding paragraphs, 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:

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

          (2)  in the case of a partnership, own more than 50 percent 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 that 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.

          Voluntary Employee Contribution may be made (1) as of the Effective
          Date, or (2) as elected by the Employer in the Adoption Agreement. 
          Voluntary Employee Contributions shall be subject to the terms of
          Section 4B.




Article II - General Provisions       -26-

          (c)  Fail-Safe Contribution.

               The Employer reserves the right to make a discretionary 
               Nonelective Contribution to the Plan for any Plan Year, if the 
               Employer determines that such a contribution is necessary to
               ensure the Actual Deferral Percentage test or the Actual
               Contribution Percentage test will be satisfied for that Plan
               Year. Such amount shall be designated by the Employer at the
               time of contribution as a Qualified Nonelective Contribution 
               and shall be known as a Fail-Safe Contribution.

               The Fail-Safe Contribution shall be made on behalf of all
               eligible non-Highly Compensated Employees who are Participants
               and who are considered under the Actual Deferral Percentage test
               or, if applicable, the Actual Contribution Percentage test, and
               shall be allocated to the Participant's Account of each such
               Participant in an amount equal to a fixed percentage of such
               Participant's Compensation. The fixed percentage shall be equal
               to the minimum fixed percentage necessary to be contributed by
               the Employer on behalf of each eligible non-Highly Compensated
               Employee who is a Participant so that the Actual Deferral
               Percentage test or, if applicable, the Actual Contribution
               Percentage test, is satisfied.

          (d)  Contributions - Changes.

               For each Plan Year, a Participant may change the amount of his
               Required Employee Contributions, Voluntary Employee
               Contributions, or Elective Deferral Contributions as often as
               the Plan Administrator allows (on a consistent and
               nondiscriminatory basis), on certain dates prescribed by the
               Plan Administrator.

          (e)  Contributions - Timing.

               (1)  Elective Deferral Contributions shall be paid by the
                    Employer to the Trust or the Insurance Company, as elected
                    by the Employer in the Adoption Agreement, but never later 
                    than 90 days following the date of deferral.             

               (2)  Matching Contributions made on other than an annual basis
                    shall be paid to the Trust or Insurance Company, as elected 
                    by the Employer in the Adoption Agreement. Matching
                    Contributions, including Additional Matching Contributions,
                    made on an annual basis shall be paid to the Trust or the
                    Insurance Company, as applicable, at the end of the Plan
                    Year, or as soon as possible on or after the last day of
                    such Plan Year, but in no event later than the date
                    prescribed by law for filing the Employer's income tax
                    return, including any extension thereof. To the extent that
                    Matching Contributions are used to purchase Life Insurance
                    Policies, then such contributions for any Plan Year may be
                    paid to the Trust when premiums for such Policies are due
                    during the Plan Year.

               (3)  Nonelective Contributions made on other than an annual
                    basis shall be paid to the Trust or Insurance Company, as
                    applicable, as elected by the Employer in the Adoption
                    Agreement. Nonelective Contributions made on an annual
                    basis shall be paid to the Trust or the Insurance Company,
                    as applicable, at the end of the Plan Year,

<PAGE>   36
                    or as soon as possible on or after the last day of such Plan
                    Year, but in any event not later than the date prescribed by
                    law for filing the Employer's income tax return, including
                    any extension thereof. To the extent that Nonelective
                    Contributions are used to purchase Life Insurance Policies,
                    then such contributions for any Plan Year may be paid to the
                    Trust when premiums for such Policies are due during the
                    Plan Year.

               (4)  Employee Contributions shall be transferred by the Employer
                    to the Trust or the Insurance Company, as elected by the
                    Employer in the Adoption Agreement, but never later than 90
                    days following the date such contributions are made by the
                    Employee.

               (5)  The Fail-Safe Contribution for any Plan Year as determined
                    above shall be paid to the Insurance Company at the end of
                    the Plan Year, or as soon as possible on or after the last
                    day of such Plan Year, but in no event later than the date
                    which is prescribed by law for filing the Employer's income
                    tax return, including any extensions thereof.

          (f)  Contributions - Allocations.

               The allocation of Nonelective Contributions shall be made in
               accordance with (1), (2), (3) or (4) below, as specified by the
               Employer in the Adoption Agreement.

               (1)  Formula A: Compensation Ratio - Not Integrated with Social
                    Security.

                    The allocation to each Participant shall be made in the
                    proportion that the Compensation paid to each Participant
                    eligible to receive an allocation bears to the Compensation
                    paid to all Participants eligible to receive an allocation.

               (2)  Formula B: Integrated with Social Security - Step Rate
                    Method.

                    Base Contribution: An amount equal to a percentage (as
                    specified in the Adoption Agreement) of the Compensation of
                    each Participant up to the Social Security Integration
                    Level;

                    Excess Contribution: In addition, an amount equal to a
                    percentage (as specified in the Adoption Agreement) of the
                    Participant's Compensation which is in excess of the Social
                    Security Integration Level, subject to the Limitations on
                    Allocations in accordance with Section 4B. This Excess
                    Contribution percentage shall not exceed the lesser of:

                    (A)  twice the Base Contribution or

                    (B)  the Base Contribution plus the greater of:

                         (i)  the old age insurance portion of the Old Age
                              Survivor Disability (OASDI) tax rate; or

                         (ii) 5.7%.

                    If the Employer has elected in the Adoption Agreement to use
                    a Social Security Integration Level that in any Plan Year is
                    the greater of $10,000 or 20% but less than 100% of the
                    Social Security Taxable

                    Cumulative Permitted Disparity Limit described in Section
                    2C.1(g), Nonelective Contributions shall be allocated in an
                    amount equal to the Excess Contribution percentage of two 
                    times such Participant's total Compensation for the Plan
                    Year.
               
                    Any remaining Nonelective Contributions or Forfeitures will
                    be allocated to each Participant's Account in the ratio
                    that each Participant's total Compensation for the Plan
                    Year bears to all Participants' total Compensation for that

                    Section 4B, for each Plan Year the allocation to each
                    Participant shall be made in accordance with the following:

                    (A)  An amount equal to 5.7% of the sum of each
                         Participant's total Compensation plus Compensation that
                         is in excess of the Social Security Integration Level
                         shall be allocated to each Participant's Account. If
                         the Employer does not contribute such amount for all
                         Participants, an amount shall be allocated to each
                         Participant's Account equal to the same proportion that
                         each Participant's total Compensation plus Compensation
                         that is in excess of the Social Security Integration
                         Level bears to the total Compensation plus Compensation
                         in excess of the Social Security Integration Level of
                         all Participants in the Plan. In the case of any
                         Participant who has exceeded the Cumulative Permitted
                         Disparity Limit described in Section 2C.1(g), two times
                         such Participant's total Compensation for the Plan Year
                         will be taken into account.

                         If the Employer has elected in the Adoption Agreement
                         to use a Social Security Integration Level that in any
                         Plan Year is the greater of $10,000 or 20% but less
                         than 100% of the Social Security Taxable Wage Base,
                         then the 5.7% limitation specified in this subsection
                         shall be adjusted in accordance with the following
                         table:

                    (B)  The balance of the Nonelective Contribution (if any),
                         shall be allocated to the Participant's Account in the
                         proportion that each Participant's Compensation bears
                         to the total Compensation of all Participants.

               (4)  Formula C: Flat Dollar Amount.

                    The allocation to each Participant shall be a flat dollar
                    amount as elected by the Employer in the Adoption Agreement.
                    Formula C may not be elected under a standardized plan.

          (g)  Allocation Requirements.

               Employer contributions shall be allocated to the accounts of
               Participants in accordance with the allocation requirement as
               specified by the Employer in its Adoption Agreement. If the
               Employer has adopted a standardized plan, the allocation of any
               nonannual contribution made by the Employer shall be made to each
               Participant who is a Participant on any day of the Contribution
               Period regardless of Hours of Service.

               Annual Overall Permitted Disparity Limit. Notwithstanding the
               preceding paragraph, for any Plan Year this Plan benefits any
               Participant who benefits under another qualified plan or
               simplified employee pension plan, as defined in Code section
               408(k), maintained by the Employer that provides for permitted
               disparity (or imputes disparity), Employer contributions and
               Forfeitures will be allocated to the account of each Participant
               who either completes more than 500 Hours of Service during the
               Plan Year or who is employed as of the last day of the Plan Year
               in the ratio that such Participant's total Compensation bears to
               the total Compensation of all Participants.

               Cumulative Permitted Disparity Limit. Effective for Plan Years
               beginning on or after January 1, 1995, the Cumulative Permitted
               Disparity Limit for a Participant is 35 total cumulative
               permitted disparity years. Total cumulative permitted years mean
               the number of years credited to the Participant for allocation or
               accrual purposes under this Plan, any other qualified plan or
               simplified employee pension plan (whether or not terminated) ever
               maintained by the Employer. For purposes of determining the
               Participant's Cumulative Permitted Disparity Limit, all years
               ending in the same calendar year are treated as the same year. If
               the Participant has not benefitted under a defined benefit or
               target benefit plan for any year beginning on or after January 1,
               1994, the Participant has no Cumulative Permitted Disparity
               Limit.

     (h)  Forfeitures.

          Forfeitures will be used in the manner elected in the Adoption
          Agreement as follows:

          (1)  To reduce Employer contributions or pay Plan expenses; or

          (2)  Allocated in accordance with the allocation formula elected in

          (3)  First, to reduce Employer contributions or pay Plan expenses,
               with any remaining Forfeitures allocated in accordance with the

     (i)  Expenses.

          The Employer may contribute to the Plan the amount necessary to pay
          any reasonable expenses of administering the Plan. In lieu of the
          Employer contributing the amount necessary to pay such charges, these
          expenses may be paid from Plan assets.

     (j)  Special Rules - Elective Deferral Contributions.

          (1)  Each Participant may elect to defer his Compensation in an

               modification of an earlier Salary Deferral Agreement) may not be
               made with respect to Compensation which is currently available
               on or before the date the Participant executed such election, or
               if later, the later of the date the Employer adopts this CODA,
               or the date such arrangement first becomes effective. Any
               elections made pursuant to this Section shall become effective
               as soon as administratively feasible.

          (2)  If elected by the Employer in the Adoption Agreement, each
               Participant may elect to defer and have allocated for a Plan
               Year all or a portion of any cash bonus paid during the Plan
               Year. A deferral election may not be made with respect to cash
               bonuses which are currently available on or before the date the
               Participant executed such election.

          (3)  Elective Deferral Contributions will be allocated to the
               Participant's Account and shall be 100 percent vested and
               nonforfeitable at all times.

          (4)  During any taxable year, no Participant shall be permitted to
               have Elective Deferral Contributions made under this Plan, or
               any other qualified plan maintained by the Employer, in excess
               of the dollar limitation contained in Code section 402(g) in
               effect at the beginning of such taxable year. If a Participant
               takes a withdrawal of Elective Deferral Contributions due to a
               Serious Financial Hardship, as provided in Section 3E.5, his
               Elective Deferral Contributions for his taxable year immediately
               following the taxable year of such distribution may not exceed
               the Code section 402(g) limit for such taxable year less the
               amount of Elective Deferral Contributions made for the
               Participant in the taxable year of the distribution.

          Elective Deferral Contributions that are in excess of the limits
          described in (4) above shall also be subject to the Section 4B
          limitations, as further provided in Section 4C.2.

          under a CODA may not be conditioned upon the completion of more than
          one (1) Year-of-Service or the attainment of more than age twenty-one
          (21).

     (7)  A Participant may modify the amount of Elective Deferral Contributions
          such Participant makes to the Plan as often as the Plan Administrator
          allows, as specified in the Adoption Agreement, but in no event not
          less frequently than once per calendar year. Such modification may be

                    Participant up to the Social Security Integration Level;

                    Excess Contribution: In addition, an amount equal to a
                    percentage (as specified in the Adoption Agreement) of the
                    Participant's Compensation which is in excess of the Social
                    Security Integration

                    Level, subject to the Limitations on Allocations in
                    accordance with Section 4B. This Excess Contribution
                    percentage shall not exceed the lesser of:     

                    (A)  twice the Base Contribution or

                    (B)  the Base Contribution plus the greater of:

                         (i)  old age insurance portion of the Old Age Survivor
                              Disability (OASDI) tax rate; or

                         (ii) 5.7%.

                    If the Employer has elected in the Adoption Agreement to use
                    a Social Security Integration Level that in any Plan Year is
                    the greater of $10,000 or 20% but less than 100% of the
                    Social Security Taxable Wage Base, then the 5.7% limitation
                    specified in 2C.2(a)(3)(B)(ii) shall be adjusted in
                    accordance with the following table:

                    However, in the case of any Participant who has exceeded the
                    Cumulative Permitted Disparity Limit described below, the
                    Employer will contribute for each Participant who either
                    completes more than 500 Hours of Service during the Plan
                    Year or is employed on the last day of the Plan Year, an
                    amount equal to the Excess Contribution percentage
                    multiplied by the Participant's total Compensation.

               Annual Overall Permitted Disparity Limit. Notwithstanding the
               preceding provisions of this Section 2C.2(a), for any Plan Year
               this Plan benefits any Participant who benefits under another
               qualified plan or simplified employee pension plan, as defined in
               Code section 408(k), maintained by the Employer that provides for
               permitted disparity (or imputes disparity), Employer
               contributions and Forfeitures will be allocated to the account of
               each Participant who either completes more than 500 Hours of
               Service during the Plan Year or who is employed as of the last
               day of the Plan Year in the ratio that such Participant's total
               Compensation bears to the total Compensation of all Participants.

               Cumulative Permitted Disparity Limit. Effective for Plan Years
               beginning on or after January 1, 1995, the Cumulative Permitted
               Disparity Limit for a Participant is 35 total cumulative
               permitted disparity years. Total cumulative permitted years mean
               the number of years credited to the Participant for allocation or
               accrual purposes under this Plan, any other qualified plan or
               simplified employee pension plan (whether or not terminated) ever
               maintained by the Employer. For purposes of

Article II - General Provisions       -35-
<PAGE>   44
               determining the Participant's Cumulative Permitted Disparity
               Limit, all years ending in the same calendar year are treated as
               the same year. If the Participant has not benefitted under a
               defined benefit or target benefit plan for any year beginning
               on or after January 1, 1994, the Participant has no Cumulative 
               Permitted Disparity Limit.

          (b)  Contributions - Participant.

               The Plan Administrator will not accept Required Employee
               Contributions or Voluntary Employee Contributions that are made
               for Plan Years beginning after the Plan Year in which this
               document is being adopted by the Employer. Required Employee
               Contributions and Voluntary Employee Contributions for Plan Years
               beginning after December 31, 1986, but before the Plan Year in
               which this document is adopted, will be limited so as to meet the
               nondiscrimination test of Code section 401(m) as provided in
               Section 4A.4.

          (c)  Contributions - Timing.

               Contributions made on other than an annual basis shall be paid to
               the Trust or Insurance Company, as applicable, not less 
               frequently than monthly or every four weeks. Contributions made 
               on an annual basis shall be paid to the Trust or the Insurance 
               Company, as applicable, at the end of the Plan Year, or as soon 
               as possible on or after the last day of such Plan Year, but in 
               any event not later than the date prescribed by law for filing  
               the Employer's income tax return, including any extension 
               thereof. To the extent that contributions are used to purchase 
               Life Insurance Policies, such contributions for any Plan Year may
               be paid to the Trust when premiums for such Policies are due 
               during the Plan Year.

          (d)  Contributions - Allocation.

               Employer Contributions shall be allocated to the Participants'
               Account in accordance with the allocation requirements as
               specified by the Employer in the Adoption Agreement. If the
               Employer has adopted a standardized plan, the allocation of any
               nonannual contribution made by the Employer shall be made for
               each Participant who is a Participant on any day of the
               Contribution Period regardless of Hours of Service.

          (e)  Forfeitures.

               Forfeitures will be used in the manner elected in the Adoption 
               Agreement as follows:

               (1)  To reduce Employer contributions or pay Plan expenses; or

               (2)  Allocated in the same manner elected in the Adoption
                    Agreement for the allocation of Employer contributions; or

               (3)  First, to reduce Employer contributions or pay Plan
                    expenses, with any remaining Forfeitures allocated in the
                    same manner elected in the Adoption Agreement for the
                    allocation of Employer contributions.

          (f)  Expenses.

               The Employer may contribute to the Plan the amount necessary to
               pay any applicable expense charges and administration charges. In
               lieu of the


Article II - General Provisions       -36-
<PAGE>   45
               Employer contributing the amount necessary to pay such charges,
               these expenses may be paid from Plan assets.

     2C.3 ROLLOVER CONTRIBUTIONS.

          If elected by the Employer in the Adoption Agreement, and without
          regard to the limitations imposed under Section 4B, the Plan may
          receive Rollover Contributions on behalf of an Employee, if the
          Employee is so entitled under Code sections 402(c), 403(a)(4), or
          408(d)(3)(A). Contributions may be rolled over either directly or
          indirectly, in the form of cash, and may be all or a portion of the
          funds eligible for rollover. Receipt of Rollover Contributions shall
          be subject to the approval of the Plan Administrator. Before approving
          the receipt of a Rollover Contribution, the Plan Administrator may
          request any documents or other information from an Employee or
          opinions of counsel which the Plan Administrator deems necessary to
          establish that such amount is a Rollover Contribution.

          If Rollover Contributions are elected by the Employer in the Adoption
          Agreement, they may be received from an Employee who is not otherwise
          eligible to participate in the Plan.  Rollover Contributions may be
          withdrawn by such Employee pursuant to the provisions of the Adoption
          Agreement and Section 3E. In addition, such Employee may direct the
          investment and transfer of amounts in his Participant's Account
          pursuant to the terms of Section 5A. Upon Termination of Employment,
          such Employee shall be entitled to a distribution of his Participant's
          Account.

     2C.4 CONTRIBUTIONS SUBJECT TO DAVIS-BACON ACT.

          If the Employer designates under the Adoption Agreement that Employer
          contributions are to be made in different amounts for different
          contracts subject to the Davis-Bacon Act or other Prevailing Wage Law,
          the Employer shall file with the Plan Administrator an irrevocable
          written designation for each Prevailing Wage Law project, stating the
          hourly contribution rate to be contributed to the Plan by the Employer
          for each class of Employees working on the project in order to comply
          with the Prevailing Wage Law applicable to the project. The
          contribution rate designation shall be irrevocable with respect to
          work on that project, although the hourly contribution rate may be
          increased prospectively by the filing of a new written contribution
          rate designation with the Plan Administrator.

     2C.5 QVEC CONTRIBUTIONS.

          The Plan Administrator will not accept QVEC Contributions which are
          made for a taxable year beginning after December 31, 1986.
          Contributions made prior to that date will be maintained in a separate
          account that will be nonforfeitable at all times. The account will
          share in the gains and losses under the Plan in the same manner as
          described in Section 5A.3 of the Plan. No part of the QVEC
          Contributions portion of the Participant's Account will be used to
          purchase Life Insurance Policies.  No part of the QVEC Contributions
          portion of the Participant's Account will be available for loans.
          Subject to Section 3C, Joint and Survivor Annuity Requirements (if
          applicable), the Participant may withdraw any part of his QVEC
          Contributions by making a written application to the Plan
          Administrator.

                          ARTICLE III - DISTRIBUTIONS

                        3A. TIMING AND FORM OF BENEFITS

3A.1 PAYMENTS OF BENEFITS. The rules and procedures for electing the timing and
     form of distribution effective for each Participant or Beneficiary shall be
     formulated and administered by the Plan Administrator in a consistent
     manner for all Participants in similar circumstances. For money purchase
     and target benefit plans, the normal form of distribution shall be a Life
     Annuity. For a profit sharing plan, the normal form of distribution shall
     be cash. For any plan, the distribution shall be made within an
     administratively reasonable time following the date the application for
     distribution is filed with the Plan Administrator.

     If elected by the Employer in the Adoption Agreement, a Participant, or his
     Beneficiary as the case may be, may elect to receive distribution of all or
     a portion of his Vested Interest in one or a combination of the following
     forms of payment:

     (a)  Single sum cash payment;

     (b)  Life Annuity;

     (c)  Installment Payments (i.e., a series of periodic single-sum cash
          payments over time, with no life contingency);

     (d)  Installment Refund Annuity (i.e., an Annuity that provides for fixed
          monthly payments for a period certain of not less than 3 nor more than
          15 years. If a Participant dies before the period certain expires, the
          Annuity will be paid to the Participant's Beneficiary for the
          remainder of the period certain. The period certain shall be chosen by
          the Participant at the time the Annuity is purchased with the
          Participant's Vested Interest. The Installment Refund Annuity is not a
          Life Annuity and in no event shall the period certain extend to a
          period which equals or exceeds the life expectancy of the
          Participant);

     (e)  Employer stock, to the extent the Participant is invested therein.

     All distributions are subject to the provisions of Section 3C, Joint and
     Survivor Annuity Requirements.

     If the value of a Participant's Vested Interest has never exceeded $3,500
     at anytime, the Employer shall indicate in the Adoption Agreement whether a
     distribution shall be made in the form of a single sum cash payment upon
     such Participant's Termination of Employment and may not be deferred or the
     Participant may elect to defer distribution until the April 1 following the
     calendar year in which he reaches age 70-1/2. If the Employer permits
     Participants to defer such distributions, failure to make an election will
     be deemed to be an election to defer to the April 1 following the calendar
     year in which the Participant reaches age 70-1/2.

     If the Participant's Vested Interest exceeds (or at the time of any prior
     distribution exceeded) $3,500, and such amount is immediately
     distributable, the Participant and the Participant's Spouse, if required,
     (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 Participant's Spouse, if required, shall be obtained in
     writing within the 90-day period ending on the Annuity


Article III - Distributions           -38-
<PAGE>   47
          Starting Date.  The "Annuity Starting Date" is the first day of the
          first period for which an amount is paid as an Annuity or any other
          form.

          An account balance is considered 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 Normal Retirement Age or age
          62.

          Instead of consenting to a distribution, the Participant may elect to
          defer the distribution until the April 1 following the calendar year
          in which he reaches age 70-1/2. Failure to make an election will be
          deemed to be an election to defer to the April 1 following the
          calendar year in which he reaches age 70-1/2.

          The Plan Administrator shall notify the Participant and the
          Participant's Spouse of the right to defer any distribution. 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.

          If the distribution is one to which Code sections 401(a)(11) and 417
          do not apply, such distribution may commence less than 30 days after
          the notice required under Code regulation section 1.411(a)-11(c) is
          given, provided that:

          (a)  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

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

          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 Section 3C.6 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 section 415. In addition, upon termination of this
          Plan, if the Plan does not offer an annuity option (purchased from a
          commercial provider) and if the Employer or any entity within the
          same controlled group as the Employer does not maintain another
          defined contribution plan (other than an employee stock ownership
          plan as defined in Code section 4975(e)(7)), then the Participant's
          account balance will, without the Participant's consent, be
          distributed to the Participant. However, if any entity within the
          same controlled group as the Employer maintains another defined in
          Code section 4975(e)(7), then the Participant's account balance will
          be transferred without the Participant's consent to the other plan if
          the participant does not consent to an immediate distribution.

          For purposes of determining the applicability of the foregoing consent
          requirements to distributions made before the first day of the first
          Plan Year


Article III - Distributions           -39-


                           

<PAGE>   48
     beginning after December 31, 1988,the Participant's vested account balance
     shall not include amounts attributable to QVEC Contributions made between
     December 31, 1981 and January 1, 1987, plus gains and minus losses thereon
     ("accumulated QVEC Contributions").  

     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.

     A Participant who terminates employment and does not consent to an
     immediate distribution shall have his distribution deferred. Such a
     distribution shall commence no later than the April 1 following the date
     the Participant attains age of 70-1/2. Loans may not be initiated for
     Participants covered by this paragraph except if, after his Termination of
     Employment, the Participant is still a party-in-interest (as defined in
     ERISA). A Participant who continues to maintain an account balance under
     the Plan may elect to withdraw an amount which is equal to any whole
     percentage (not to exceed 100%) from his Participant's Account. Such an
     election shall be made in accordance with Section 3E. Such Participant as
     described herein shall have the authority to direct the transfer of his
     Vested Interest in accordance with Section 5A.2.  The election to defer
     distribution may be revoked at any time by submitting a written request to
     the Plan Administrator. Any Forfeiture attributable to withdrawals shall be
     subject to the requirements of Sections 3D.1 and 3E.8 of the Plan. A
     Participant whose Termination of Employment is on or after his Early
     Retirement Date may elect to defer the distribution subject to the
     requirements of Section 3B.

3A.2 COMMENCEMENT OF BENEFITS. Unless the Participant elects otherwise,
     distribution of benefits will begin no later than the 60th day after the
     latest of the close of the Plan Year in which:

     (a)  The Participant attains age 65 (or Normal Retirement Age, if earlier);

     (b)  The 10th anniversary of the year in which the Participant commenced
          participation in the Plan occurs; or, 

     (c)  The Participant terminates Service with the Employer.

     Notwithstanding the foregoing, the failure of a Participant and Spouse to
     consent to a distribution, if required, while a benefit is immediately
     distributable within the meaning of Section 3A.1 of the Plan, shall be
     deemed to be an election to defer distribution to the date the Participant
     attains age 70-1/2.

     However, in no event shall distribution of that portion of a Participant's
     Account attributable to Elective Deferral Contributions, Qualified Matching

          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 so recalculated. The applicable calendar
          year shall be the first Distribution Calendar Year, and if Life
          Expectancy is being recalculated, such succeeding calendar year.

     (b)  DESIGNATED BENEFICIARY. The term Designated Beneficiary means the

          the calendar year which contains the Participant's Required Beginning
          Date. For distributions beginning after the Participant's death, the

          distributions described in Section 3B.3(b)(2)) by the time
          distributions are required to begin, Life Expectancies shall be
          recalculated annually. Such election shall be irrevocable as to the
          Participant (or Spouse) and shall apply to all subsequent years. The
          Life Expectancy of a non-Spouse Beneficiary may not be recalculated.

     (f)  PARTICIPANT'S BENEFIT. The term Participant's Benefit means:

          (1)  The Participant's Vested Interest 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

               the Valuation Calendar Year after the valuation date.

          (2)  Exception for second Distribution Calendar Year. For purposes of
               paragraph (1) above, 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.

     (g)  REQUIRED BEGINNING DATE. The term Required Beginning Date means:

          (1)  General Rule. The first 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.

               (3)  Once distributions have begun to a 5-Percent Owner under
                    this Section, they must continue to be distributed, even if

                    year.

     3B.2 DISTRIBUTION REQUIREMENTS.

          (a)  Except as otherwise provided in Section 3C, Joint and Survivor
               Annuity Requirements, the requirements of this Section 3B shall
               apply to any distribution of a Participant's Accrued Benefit and
               will take precedence over any inconsistent provisions of this
               Plan. Unless otherwise specified, the provisions of this Section

               (2)  The life of the Participant and a Designated Beneficiary;

                    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

                    beginning with distributions for the first Distribution
                    Calendar Year, must at least equal the quotient obtained by
                    dividing the Participant's benefit by the Applicable Life
                    Expectancy.

               (2)  For calendar years beginning before January 1, 1989, if the

                    50% of the present value of the amount available for
                    distribution is paid within the Life Expectancy of the

                    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

                    first Distribution Calendar Year must be made on or before
                    the Participant's Required Beginning Date. The minimum

          (e)  Other Forms. 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

               the Participant's death.

          (b)  Distributions Beginning After Death. If the Participant dies
               before distribution of his entire Vested Interest begins,
               distribution of the Participant's entire Vested 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 (1) or (2) below:

               (1)  If any portion of the Participant's entire Vested Interest
                    is payable to a Designated Beneficiary, distributions may be
                    made over 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;

               (2)  If the Designated Beneficiary is the Participant's surviving
                    Spouse, the date distributions are required to begin in
                    accordance with (1) above shall not be earlier than the
                    later of (i) December 31 of the calendar year immediately
                    following the calendar year in which the Participant died
                    and (ii) 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
               Section 3B.3(b) 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

               contains the fifth anniversary of the Participant's date of
               death. If the Participant has no Designated Beneficiary, or if
               the Designated Beneficiary does not elect a method of
               distribution, distribution of the Participant's entire Vested
               Interest must be completed by December 31 of the calendar year
               containing the fifth anniversary of the Participant's death and

               dies after the Participant, but before payments to such Spouse
               begin, the provisions of this Section, with the exception of
               paragraph (b)(2) therein, shall be applied as if the surviving
               Spouse were the Participant.

          (d)  For purposes of this Section, distribution of a Participant's
               entire Vested Interest pursuant to Section 3B.3(b) is considered
               to begin on the Participant's Required Beginning Date (or, if
               paragraph (c) above is applicable, the date distribution is
               required to begin to the Surviving Spouse). If distribution in
               the form of an Annuity irrevocably commences to the Participant
               before the Required Beginning Date, the date distribution is
               considered to begin is the date distribution actually commences.

               be made in accordance with all of the following requirements
               (regardless of when such distribution commences):

               (1)  The distribution by the Plan is one which would not have
                    disqualified such Plan under Code section 401(a)(9) as in

               (2)  The distribution is in accordance with a method of
                    distribution designated by the Employee whose entire Vested
                    Interest in the Plan is being distributed or, if the
                    Employee is deceased, by a Beneficiary of such Employee.

               (3)  Such designation was in writing, was signed by the Employee

                    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 distribution to be made upon the death of the Employee.

          (c)  For any distribution that commences before January 1, 1984, but
               continues after December 31, 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 subsections (a)(1) and (5).

          (d)  If a designation is revoked, any subsequent distribution must
               satisfy the requirements of Code section 401(a)(9) and related
               regulations. If a designation is revoked subsequent to the date
               distributions are required to begin, the Plan 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 related regulations, except for the TEFRA
               section 242(b)(2) election. For calendar years beginning after
               December 31, 1988, such distributions must meet the minimum
               distribution incidental benefit requirements in regulations
               section 1.401(a)(9)-2. 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
               from one plan to another plan, the rules in Q&A J-2 and Q&A J-3
               shall apply.

               3C. JOINT AND SURVIVOR ANNUITY REQUIREMENTS

     3C.1 APPLICABILITY. Except as provided in Section 3C.6, the provisions of
          this Section 3C 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 Section 3C.7.

     3C.2 DEFINITIONS. The following definitions shall apply to this Section 3C.

          (a)  EARLIEST RETIREMENT AGE. The term Earliest Retirement Age means
               the earliest date on which, under the Plan, the Participant
               could elect to receive retirement benefits.

          (b)  ELECTION PERIOD. The term Election Period means 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 he attains age
               35, with respect to the Vested Account Balance as of the date of
               separation, the election period shall begin on the date of
               separation.

               Pre-age 35 waiver: A Participant who will not yet attain age 35
               as of the end of any current Plan Year may make a special
               Qualified Election to waive the Qualified Preretirement 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 Preretirement Survivor Annuity in such terms as are
               comparable to the explanation required under Section 3C.5(a).
               Except as provided in Section 3C.6, Qualified Preretirement
               Survivor 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 Section 3C.

          (c)  QUALIFIED ELECTION. The term Qualified Election means a waiver
               of a Qualified Joint and Survivor Annuity or a Qualified
               Preretirement Survivor Annuity. Any waiver of a Qualified Joint
               and Survivor Annuity or a Qualified Preretirement Survivor
               Annuity shall not be effective unless: (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 a Plan
               representative 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

Article III - Distributions            -47-     
<PAGE>   56
               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 Section 3C.5 below.

          (d)  QUALIFIED JOINT AND SURVIVOR ANNUITY. The term Qualified Joint
               and Survivor Annuity mean an immediate Annuity for the life of
               the Participant with a survivor Annuity for the life of the
               Spouse which is not less than 50 percent and not more than 100
               percent of the amount of the Annuity which is payable during the
               joint lives of the Participant and the Spouse and which is the
               amount of benefit which can be purchased with the Participant's
               Vested Account Balance. The percentage of the survivor annuity
               under the Plan shall be 50 percent (unless a different percentage
               is elected by the Participant).

          (e)  VESTED ACCOUNT BALANCE. The term Vested Account Balance means the
               aggregate value of the Participant's vested account balances
               derived from contributions made by both the Participant and
               Employer, whether vested before or upon death, including the
               proceeds of insurance contracts, if any, on the Participant's
               life and Rollover Contributions. The provisions of this Section
               3C shall apply to a Participant who is vested in amounts
               attributable to Employer contributions, Employee Contributions
               (or both) made under this Plan at the time of death or
               distribution.

     3C.3 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
          Earliest Retirement Age under the Plan.

     3C.4 QUALIFIED PRERETIREMENT 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 the Annuity Starting
          Date, then no less than 50 percent (or 100 percent if so elected in
          the Adoption Agreement) of the Participant's Vested Account Balance
          shall be applied toward the purchase of an Annuity for the life of the
          surviving Spouse. If less than 100 percent is selected, then the
          remaining portion of the Vested Account Balance shall be paid to the
          Participant's Beneficiary. If less than 100 percent of the Vested
          Account Balance is paid to the surviving Spouse, the amount of
          Employee Contributions allocated to the surviving Spouse will be in
          the same proportion as the Employee Contributions bears to the total
          Vested Account Balance of the Participant. The surviving Spouse may
          elect to have such Annuity distributed within a reasonable period
          after the Participant's death.

     3C.5 NOTICE REQUIREMENTS.

          (a)  In the case of a Qualified Joint and Survivor Annuity, the Plan
               Administrator shall no less than 30 days and no more than 90 days
               prior to 



Article III - Distributions           -48-

<PAGE>   57
               the Annuity Starting Date provide each Participant with a written
               explanation of: (i) the terms and conditions of a Qualified
               Joint and Survivor Annuity; (ii) the Participant's right to make
               and the effect of an election to waive the Qualified Joint and
               Survivor Annuity form of benefit; (iii) the rights of a
               Participant's Spouse; and (iv) the right to make, and the effect
               of, a revocation of a previous election to waive the Qualified
               Joint and Survivor Annuity.

          (b)  In the case of a Qualified Preretirement Survivor Annuity, the
               Plan Administrator shall provide each Participant within the
               applicable period (described in subsection (c) below) for such
               Participant a written explanation of the Qualified Preretirement
               Survivor Annuity in such terms and in such manner as would be
               comparable to the explanation provided for meeting the
               requirements of Section 3C.5(a) applicable to a Qualified Joint
               and Survivor Annuity.

          (c)  The "applicable period" for a Participant is whichever of the
               following periods ends last: (i) 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; (ii) a reasonable
               period ending after the individual becomes a Participant; (iii) a
               reasonable period ending after the Qualified Joint and Survivor
               Annuity is no longer fully subsidized; (iv) a reasonable period
               ending after this Section 3C first applies to the Participant.
               Notwithstanding the foregoing, notice must be provided within a
               reasonable period ending after separation from Service before
               attaining age 35.

               For purposes of applying the preceding paragraph, a reasonable
               period ending after then enumerated events described in (ii),
               (iii) and (iv) 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 he attains
               age 35, 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 thereafter returns to
               employment with the Employer, the applicable period for such
               Participant shall be redetermined.

          (d)  Notwithstanding the other requirements of this Section, the
               respective notices prescribed by this Section need not be given
               to a Participant if (1) the Plan "fully subsidizes" the costs of
               a Qualified Joint and Survivor Annuity or Qualified Preretirement
               Survivor Annuity, and (2) the Plan does not allow the Participant
               to waive the Qualified Joint and Survivor Annuity or Qualified
               Preretirement Survivor Annuity and does not allow a married
               Participant to designate a nonspouse Beneficiary. For purposes of
               this Section 3C.5(d), a Plan fully subsidizes the costs of a
               benefit if no increase in cost or decrease in benefits to the
               Participant may result from the Participant's failure to elect
               another benefit.

     3C.6 SAFE HARBOR RULES.

          (a)  This Section 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 December 31, 1988, from or
               under a separate account

Article III - Distributions           -49-
<PAGE>   58
               attributable solely to accumulated QVEC Contributions (as
               described in Section 3A.1), and maintained on behalf of a
               Participant in a money purchase pension plan (including a target
               benefit plan), if the following conditions are met: (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.

          (b)  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.

          (c)  The Participant may waive the spousal death benefit described in
               this Section 3C.6 at any time provided that no such waiver shall
               be effective unless it satisfies the conditions of Section
               3C.2(c) (other than the notification requirement referred to
               therein) that would apply to the Participant's waiver of the
               Qualified Preretirement Survivor Annuity.

          (d)  If this Section 3C.6 is operative, than the other provisions of
               this Section 3C, other than Section 3C.7, shall be inoperative.

               This Section 3C.6 shall not be operative with respect to a
               Participant in a profit sharing plan if the plan is a direct or
               indirect transferee of a defined benefit plan, money purchase
               plan, a target benefit plan, stock bonus, or profit sharing plan
               that is subject to the survivor annuity requirements of Code
               sections 401(a)(11) and 417.

          (e)  For purposes of this Section 3C.6, the term Vested Account
               Balance shall mean, in the case of a money purchase pension plan
               or a target benefit plan, the Participant's separate account
               balance attributable solely to accumulated QVEC Contributions
               (as described in Section 3A.1). In the case of a profit sharing
               plan, the term Vested Account Balance shall have the same
               meaning as provided in Section 3C.2(e).

     3C.7 TRANSITIONAL RULES.

          (a)  Any living Participant not receiving benefits on August 23,
               1984, who would otherwise not receive the benefits prescribed by
               the previous Sections of this Section 3C must be given the
               opportunity to elect to have the prior Sections of this Section
               3C 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 vesting Service when he 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 benefits paid in accordance with Section
               3C.7(d).


Article III - Distributions           -50-
<PAGE>   59
          (c)  The respective opportunities to elect (as described in Sections
               3C.7(a) and 3C.7(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.

          (d)  Any Participant who has elected pursuant to Section 3C.7(b), and
               any Participant who does not elect under Section 3C.7(a), or who
               meets the requirements of Section 3C.7(a), except that such
               Participant does not have at least 10 years of vesting Service
               when he separates from Service, shall have his benefits
               distributed in accordance with all of the following requirements
               if benefits would have been payable in the form of a Life
               Annuity:

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

                    (A)  Begins to receive payments under the Plan on or after
                         Normal Retirement Age; or

                    (B)  Dies on or after Normal Retirement Age while still
                         working for the Employer; or

                    (C)  Begins to receive payments on or after the Qualified
                         Early Retirement Age; or

                    (D)  Separates from Service on or after attaining Normal
                         Retirement Age (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.

               (2)  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.

                         3D. TERMINATION OF EMPLOYMENT


     3D.1 DISTRIBUTION.  A Participant who terminates employment shall be 
          entitled to receive a distribution of his entire Vested Interest.
          Such distribution shall be further subject to the terms and conditions
          of Section 3C. The method used, as elected by the Employer in the
          Adoption Agreement, is one of the following:


          (a)  Immediate (Cash-Out Method)

               If at the time of his Termination of Employment the Participant
               is not 100% vested and does not take a distribution from the
               portion of his Vested Interest that is attributable to
               contributions made by the Employer, the non-vested portion of
               his Participant's Account will become a Forfeiture upon the date
               such terminated Participant incurs 5 consecutive 1-Year
               Breaks-in-Service.

               However, if at the time of his Termination of Employment the
               Participant is not 100% vested and does take a distribution from
               the portion of his Vested Interest that is attributable to
               contributions made by the Employer, or if the Participant is 0%
               vested, the non-vested portion of his Participant's Account will
               become a Forfeiture immediately upon the Participant's
               Termination of Employment date.

               If a Participant whose non-vested portion of his Participant's
               Account became a Forfeiture in accordance with the terms of the
               preceding paragraph is later rehired by the Employer and
               re-enrolls in the Plan before incurring 5 consecutive 1-Year
               Breaks-in-Service, then the amount of the Forfeiture shall be
               restored to the Participant's Account by the Employer in
               accordance with the repayment provision elected by the Employer
               in the Adoption Agreement and described in Section 3D.2.

          (b)  1-Year Break-in-Service (Cash-Out Method).

               If at the time of his Termination of Employment the Participant 
               is not 100% vested and does not take a distribution from the 
               portion of his Vested Interest that is attributable to 
               contributions made by the Employer, the non-vested portion of his
               Participant's Account will become a Forfeiture upon the date such
               terminated Participant incurs 5 consecutive 1-Year Breaks-in-
               Service.

               However, if at the time of his Termination of Employment the
               Participant is not 100% vested and does take a distribution from
               the portion of his

Article III - Distributions           -52-                    

                           
<PAGE>   61
               Vested Interest that is attributable to contributions made by the
               Employer, or if the Participant is 0% vested, the non-vested
               portion of his Participant's account will become a Forfeiture
               upon the date such terminated Participant incurs a 1-Year
               Break-in-Service.

               If a terminated Participant, whose non-vested portion of his
               Participant's Account became a Forfeiture in accordance with the
               terms of the preceding paragraph, is later rehired by the
               Employer and re-enrolls in the Plan before incurring 5
               consecutive 1-year Breaks-in-Service, then the amount of the
               Forfeiture shall be restored to the Participant's Account by the
               Employer in accordance with the repayment provision elected by
               the Employer in the Adoption Agreement and described in Section
               3D.2.

          (c)  5 Consecutive 1-Year Breaks-in-Service.

               If at the time of his Termination of Employment the Participant
               is not 100% vested, the non-vested portion of his Participant's
               Account will become a Forfeiture upon the date the terminated
               Participant incurs 5 consecutive 1-Year Breaks-in-Service.

     3D.2 REPAYMENT OF PRIOR DISTRIBUTION.

          If a terminated Participant is later rehired by the Employer and
          re-enrolls in the Plan, the following Optional Payback or Required
          Payback provisions, as elected by the Employer in the Adoption
          Agreement, will apply:

          (a)  Optional Payback:

               (1)  If the Participant was 0% vested at his Termination of
                    Employment and did not incur 5 consecutive 1-Year
                    Breaks-in-Service after such date, the amount which became a
                    Forfeiture, if any, shall be restored by the Employer at the
                    time such Participant re-enrolls in the Plan.

               (2)  If the Participant was vested but not 100% vested at his
                    Termination of Employment and did not incur 5 consecutive
                    1-Year Breaks-in-Service after such date, the amount which
                    became a Forfeiture, if any, shall be restored by the
                    Employer at the time such Participant re-enrolls in the
                    Plan. In addition, the Participant may repay the full
                    amount of the distribution attributable to the Employer
                    contributions, if any, made at his Termination of
                    Employment. Such repayment of Employer contributions,
                    however, must be made before the Participant has incurred 5
                    consecutive 1-Year Breaks-in-Service following the date he
                    received the distribution or five years after the
                    Participant is rehired by the Employer, whichever is
                    earlier. 

               (3)  If the Participant had incurred 5 consecutive 1-Year
                    Breaks-in-Service after his termination of Employment, the
                    amount of the Participant's Account that became a Forfeiture
                    shall remain a Forfeiture and such Participant shall be
                    prohibited from repaying a distribution made at his
                    Termination of Employment.

          (b)  Required Payback:

               (1)  If the Participant was 0% vested at his Termination of
                    Employment and did not incur 5 consecutive 1-Year
                    Breaks-in-Service after such date, the amount which became a
                    Forfeiture, if any, shall be 


Article III - Distributions           -53-
<PAGE>   62
                    restored by the Employer at the time such Participant
                    re-enrolls in the Plan.

               (2)  If the Participant was vested but not 100% vested at his
                    Termination of Employment and did not incur 5 consecutive
                    1-Year Breaks-in-Service after such date, the Participant
                    shall be required to repay the full amount of the
                    distribution attributable to Employer contributions, if
                    any, made at his Termination of Employment. Such repayment
                    of Employer contributions, however, must be made before the
                    Participant has incurred 5 consecutive 1-Year
                    Breaks-in-Service following the date he received the
                    distribution or five years after the Participant is rehired
                    by the Employer, whichever is earlier.

                    When the Participant makes such repayment, the amount which
                    became a Forfeiture, if any, shall be restored by the
                    Employer at the same time such repayment is made. However,
                    if the Participant does not repay the distribution made in
                    accordance with this Section 3D within the period of time
                    specified above, that Forfeiture shall remain a Forfeiture.

               (3)  If the Participant had incurred 5 consecutive 1-Year
                    Breaks-in-Service after his Termination of Employment, the
                    amount of the Participant's Account that became a
                    Forfeiture shall remain a Forfeiture and such Participant
                    shall be prohibited from repaying the distribution made at
                    his Termination of Employment.

     3D.3 LIFE INSURANCE POLICY. If all or any portion of the value of any Life
          Insurance Policy on the Participant's life will become a Forfeiture,
          the Participant shall have the right to buy such policy from the
          Trustee for the then value of such policy less the value of any
          Vested Interest therein, within 30 days after written notice from the
          Trustee is mailed to his last known address.

     3D.4 NO FURTHER RIGHTS OR INTEREST. A Participant shall have no further
          interest in or any rights to any portion of his Participant's Account
          that becomes a Forfeiture due to his Termination of Employment once
          the Participant incurs 5 consecutive 1-Year Breaks-in-Service in
          accordance with Section 2A.4.

     3D.5 FORFEITURE. Any Forfeiture arising in accordance with the provisions
          of Section 3D.1 shall be treated as follows:

          Any amount of Forfeitures shall be used in accordance with (a), (b),
          or (c) below, in the manner set forth in Section 2C.

          (a)  Employer Credit. Forfeitures shall be used by the Employer to
               reduce and in lieu of the Employer contribution next due under
               Section 2C, or to pay Plan expenses, at the earliest opportunity
               after such Forfeiture becomes available.

          (b)  Reallocation. Forfeitures shall be allocated in accordance with
               the allocation formula of the contributions from which they
               arose.

          (c)  Employer Credit and Reallocation of Remainder. Forfeitures shall
               first be used to reduce and in lieu of the Employer contribution
               next due under Section 2C, or to pay Plan expenses, at the
               earliest opportunity after such Forfeiture becomes available.
               Any Forfeitures remaining following use as an Employer credit
               shall be allocated in accordance with the allocation formula of
               the contributions from which they arose.

Article III -  Distributions              -54-
<PAGE>   63
          Notwithstanding anything above to the contrary, if Forfeitures are
          generated immediately or upon the occurrence of a 1-Year
          Break-in-Service, and a former Participant returns to employment with
          the Employer after Forfeitures are generated but prior to the
          occurrence of 5 consecutive 1-Year Breaks-in-Service, Forfeitures, if
          any, will be first be used to make whole the nonvested account of
          such Participant, equal to the value of the nonvested account at the
          time the Participant terminated employment with the Employer in
          accordance with the applicable provisions of Section 3D.2. In the
          event that the available Forfeitures are not sufficient to make whole
          the nonvested account, the Employer will make an additional
          contribution sufficient to make the nonvested account whole.

     3D.6 LOST PARTICIPANT. If a benefit is forfeited because the Participant
          or Beneficiary cannot be found, as discussed in Section 5D.7, such
          benefit will be reinstated if a claim is made by the Participant or
          Beneficiary.

     3D.7 DEFERRAL OF DISTRIBUTION. If elected by the Employer, and as
          discussed in Section 3A.1, a Participant who terminates employment
          and does not consent to an immediate distribution shall have his
          distribution deferred (and may be responsible for all fees and
          expenses associated with maintaining his account in a deferred
          status).

                                3E. WITHDRAWALS

     3E.1 WITHDRAWAL - EMPLOYEE CONTRIBUTIONS.

          (a)  Required Employee Contributions. If the Employer has elected in
               its Adoption Agreement to allow for a withdrawal of Required
               Employee Contributions and earnings thereon, then a Participant
               may elect to withdraw from his Participant's Account an amount
               equal to any whole percentage (not exceeding 100%) of his entire
               Vested Interest in his Participant's Account attributable to
               Required Employee Contributions plus any income and minus any
               loss thereon. On the date the election becomes effective, the
               Participant shall be suspended from making any further
               contributions to the Plan, and from having any Matching
               Contributions made on his behalf for a period, as elected by the
               Employer in its Adoption Agreement.

          (b)  Voluntary Employee Contributions. If the Employer has elected in
               its Adoption Agreement to allow for the withdrawal of Voluntary
               Employee Contributions and earnings thereon, then a Participant
               may elect to withdraw from his Participant's Account an amount
               which is equal to any whole percentage (not exceeding 100%) of
               his entire Vested Interest in his Participant's Account
               attributable to Voluntary Employee Contributions plus any income
               and minus any loss thereon.

          (c)  Prior Required Employee Contributions. If the Employer has
               elected in its Adoption Agreement to allow for a withdrawal of
               Prior Required Employee Contributions and earnings thereon, then
               a Participant may elect to withdraw from his Participant's
               Account an amount equal to any whole percentage (not exceeding
               100%) of his entire Vested Interest in his Participant's Account
               attributable to Prior Required Employee Contributions plus any
               income and minus any loss thereon.

          (d)  Prior Voluntary Employee Contributions. If the Employer has
               elected in its Adoption Agreement to allow for withdrawal of
               Prior Voluntary Employee


ARTICLE III - DISTRIBUTIONS              -55-
<PAGE>   64
               Contributions and earnings thereon, then a Participant may elect
               to withdraw from his Participant's Account an amount which is
               equal to any whole percentage (not exceeding 100%) of the entire
               Vested Interest in his Participant's Account attributable to
               Prior Voluntary Employee Contributions plus any income and minus
               any loss thereon.

          If a Participant elects a withdrawal under the provisions of this
          Section, he may not elect another withdrawal under this Section for an
          additional period specified by the Employer in its Adoption Agreement.

          The Participant shall notify the Plan Administrator in writing of his
          election to make a withdrawal under this Section. Any such election
          shall be effective as of the date specified in such notice, which date
          must be at least 15 days after notice is filed.

          No Forfeitures will occur solely as a result of an Employee's
          withdrawal of Employee Contributions.

     3E.2 WITHDRAWAL - ELECTIVE DEFERRAL CONTRIBUTIONS. If the Participant has
          attained age 59-1/2, and if selected by the Employer in its Adoption
          Agreement, the Participant may elect to withdraw from his
          Participant's Account an amount which is equal to any whole percentage
          (not exceeding 100%) of his Vested Interest in his Participant's
          Account attributable to his Elective Deferral Contributions and
          earnings thereon.

          The Participant shall notify the Plan Administrator in writing of his
          election to make a withdrawal under this Section. Any such election
          shall be effective as of the date specified in such notice, which date
          must be at least 15 days after notice is filed.

     3E.3 WITHDRAWAL - EMPLOYER CONTRIBUTIONS. If the Employer has specified in
          its Adoption Agreement that withdrawals of Matching Contributions,
          Nonelective Contributions, or Prior Employer Contributions, if
          applicable, are permitted, a Participant, who has been a Participant
          for at least 60 consecutive months, may elect to withdraw from his
          Participant's Account an amount equal to a whole percentage (not to
          exceed 100%) of his Vested Interest in his Participant's Account
          attributable to Matching Contributions (and reallocated Forfeitures, 
          if applicable), Nonelective Contributions (and reallocated
          Forfeitures, if applicable), or Prior Employer Contributions (and
          reallocated Forfeitures, if applicable), along with earnings. On the
          date the election becomes effective, the Participant may be suspended
          from making Employee Contributions and Elective Deferral
          Contributions, if any, and from having Employer contributions made on
          his behalf for a period of time, as selected by the Employer in its
          Adoption Agreement. In lieu of or in addition to the 60-months of
          participation requirement, the Employer may specify in the Adoption
          Agreement that withdrawal of Employer contributions, to the extent
          vested, shall be available upon or following the attainment of age
          59-1/2.
          

          In the event a Participant's suspension period occurs during a year
          (or years) when no Employer contributions are made, such suspension
          shall be taken into account when the next Employer contribution(s) is
          made.

          The Participant shall notify the Plan Administrator in writing of his
          election to make a withdrawal under this Section. Any such election
          shall be effective as of the date specified in such notice, which date
          must be at least 15 days after notice is filed.

          and 7B.7(e), if the Plan is a profit sharing plan or a thrift plan,
          and if the Employer has elected in its Adoption Agreement to permit
          withdrawals due to the occurrence of events that constitute Serious
          Financial Hardships to a Participant, such Participant may withdraw
          all or a portion of his Vested Interest (excluding Elective Deferral
          Contributions, Qualified Nonelective Contributions, Qualified Matching
          Contributions, and earnings on these contributions). Such Serious
          Financial Hardship must be shown by positive evidence submitted to the
          Plan Administrator that the hardship is of sufficient magnitude to
          impair the Participant's financial security. Withdrawals shall be
          determined in a consistent and nondiscriminatory manner, and shall not
          affect the Participant's rights under the Plan to make additional
          withdrawals or to continue to be a Participant.

     3E.5 WITHDRAWAL FOR SERIOUS FINANCIAL HARDSHIP OF ELECTIVE DEFERRAL
          CONTRIBUTIONS. If the Employer has selected in its Adoption Agreement,
          a distribution may be made on account of Serious Financial Hardship if
          subparagraphs (a) and (b) of this Section are satisfied. The funds
          available for withdrawal shall be the portion of a Participant's
          Account attributable to Elective Deferral Contributions, including any
          earnings credited to the Participant's Account as of the end of the
          last Plan Year ending before July 1, 1989 ("pre-1989 earnings"), and
          if applicable, Qualified Matching Contributions credited to the
          Participant's Account as of the end of the last Plan Year ending
          before July 1, 1989, Qualified Nonelective Contributions credited to
          the Participant's Account as of the end of the last Plan Year ending
          before July 1, 1989, and any pre-1989 earnings attributable to
          Qualified Matching Contributions, or Qualified Nonelective
          Contributions. Qualified Matching Contributions credited to the
          Participant's Account after the end of the last Plan Year ending
          before July 1, 1989, Qualified Nonelective Contributions credited to
          the Participant's Account after the end of the last Plan Year ending
          before July 1, 1989, and earnings on Elective Deferral Contributions,
          Qualified Matching Contributions, and Qualified Nonelective
          Contributions credited after the end of the last Plan Year ending
          before July 1, 1989 shall not be eligible for withdrawal under this
          Section. For purposes of this Section, a distribution may be made on
          account of a hardship only if the distribution is made on account of
          an immediate and heavy financial need of the Employee where such
          Employee lacks other available resources.

          (a)  The following are the only financial needs considered immediate
               and heavy for purposes of this section:

               (i)   Expenses for medical care described in Code section 213(d)
                     previously incurred by the Employee, the Employee's Spouse,
                     or any dependents of the Employee (as defined in Code
                     section 152) or necessary for these persons to obtain
                     medical care described in Code section 213(d);

               (ii)  Costs directly related to the purchase of a principal
                     residence for the Employee (excluding mortgage payments);

               (iii) Payments necessary to prevent the eviction of the Employee
                     from the Employee's principal residence or foreclosure on
                     the mortgage on that residence; or


Article III - Distributions           -57-
<PAGE>   66
               (iv)      Tuition payments, related educational fees and amounts
                         distributed for the payment of room-and-board expenses
                         for the next 12 months of post-secondary education for
                         the Employee, his or her Spouse, or any of his or her
                         dependants.

          (b)  To the extent the amount of distribution requested does not
               exceed the amount required to relieve the Participant's financial
               need, such distribution will be considered as necessary to
               satisfy an immediate and heavy financial need of the Employee
               only if:

               (i)       The Employee has obtained all distributions, other than
                         hardship distributions, and all nontaxable loans under
                         all plans maintained by the Employer;

               (ii)      All plans maintained by the Employer provide that the
                         Employee's Elective Deferral Contributions and if
                         applicable, Employee Contributions, will be suspended
                         for 12 months after the receipt of the hardship
                         distribution;

               (iii)     The distribution is not in excess of the amount of the
                         immediate and heavy financial need (including amounts
                         necessary to pay any federal, state, or local income
                         taxes or penalties reasonably anticipated to result
                         from the distribution); and

               (iv)      All plans maintained by the Employer provide that the
                         Employee may not make Elective Deferral Contributions
                         for the Employee's taxable year immediately following
                         the taxable year of the hardship distribution in excess
                         of the applicable limit under Code section 402(g) for
                         such taxable year less the amount of such Employee's
                         Elective Deferral Contributions for the taxable year of
                         the hardship distribution.

     3E.6 WITHDRAWAL - QVEC CONTRIBUTIONS AND ROLLOVER CONTRIBUTIONS. If
          selected by the Employer in its Adoption Agreement, a Participant may
          elect to withdraw from his Participant's Account as often during each
          Plan Year as elected by the Employer in the Adoption Agreement, any
          amount up to 100% of his entire Vested Interest in his Participant's
          Account attributable to his QVEC Contributions or Rollover
          Contributions along with earnings thereon.

          The Participant shall notify the Plan Administrator in writing of his
          election to make a withdrawal under this Section. Any such election
          shall be effective as of the date specified in such notice, which date
          must be at least 15 days after notice is filed.

     3E.7 NOTIFICATION. The Participant shall notify the Plan Administrator in
          writing of his election to make a withdrawal under Section 3E. Any
          such election shall be effective as of the date specified in such
          notice, which date must be at least 15 days after such notice is
          filed. Payment of the withdrawal shall be subject to the terms and
          conditions of Section 3A. All withdrawals made under the provisions of
          Section 3E shall be subject to the spousal consent requirements of
          Section 3C, as applicable.



Article III - Distributions           -58-
<PAGE>   67
     3E.8  VESTING CONTINUATION. In the event a partially vested Participant
           takes a withdrawal of less than 100% of his Vested Interest in
           accordance with Section 3E.3 or 3E.4 or 3E.5, the remaining portion
           of his Participant's Account attributable to Employer contributions
           shall vest according to the formula as set forth in Section 1.75.

     3E.9  WITHDRAWAL - PARTICIPANT'S EMPLOYER STOCK ACCOUNT. The ability of a
           Participant who is subject to the reporting requirements of section
           16(a) of the Securities Exchange Act of 1934 (the "Act") to make
           withdrawals or investment changed involving the Participant's
           Employer Stock Account may be restricted by the Plan Administrator to
           comply with the rules under section 16(b) of the Act.

     3E.10 WITHDRAWAL BY TERMINATED PARTICIPANTS. Terminated Participants who
           have deferred distribution of their benefit may make withdrawals from
           the Plan in the same manner as selected by the Employer in its
           Adoption Agreement for withdrawals preceding termination.

                              3F. DIRECT ROLLOVERS

     3F.1  DEFINITIONS.

           (a) DIRECT ROLLOVER. The term Direct Rollover means a payment by the
               Plan to the Eligible Retirement Plan specified by the
               Distributee.

           (b) DISTRIBUTEE. The term Distributee means an Employee or former
               Employee. In addition, the Employee's or former Employee's
               surviving Spouse and the Employee's or former Employee's Spouse
               who is the Alternate Payee under a QDRO, are Distributees with
               regard to the interest of the Spouse or former Spouse.

           (c) ELIGIBLE RETIREMENT PLAN. The term Eligible Retirement Plan means
               an individual retirement account described in Code section
               408(a), an individual retirement annuity described in Code
               section 408(b), an annuity plan described in Code section 403(a),
               or a qualified plan describing Code section 401(a), that accepts
               the Distributee's Eligible Rollover Distribution.  However, in
               the case of an Eligible Rollover Distribution to the surviving
               Spouse, an Eligible Retirement Plan is an individual retirement
               account or an individual retirement annuity.

           (d) ELIGIBLE ROLLOVER DISTRIBUTION. The term Eligible Rollover
               Distribution means any distribution of all or any portion of the
               balance to the credit of the Distributee, except that an Eligible
               Rollover Distribution does not include: any distribution that is
               one of a series of substantially equal periodic payments (not
               less frequently than annually) made for the life (of Life
               Expectancy) of the Distributee or the joint lives (or joint life
               expectancies) of the Distributee and the Distributee's designated
               Beneficiary, or for a specified period of ten years or more; any
               distribution to the extent such distribution is required under
               Code section 401(a)(9); and the portion of any distribution that
               is not includable in gross income (determined without regard to
               the exclusion for net unrealized appreciation with respect to
               employer securities); and any other distribution(s) that is
               reasonably expected to total less than $200 during a year.

     3F.2  DIRECT ROLLOVERS. This Section applies to distributions made on or
           after January 1, 1993. Notwithstanding any provision of the Plan to
           the contrary that 


Article III - Distributions           -59-
<PAGE>   68
          would otherwise limit a Distributee's election under this Section, a
          Distributee may elect, at the time and in the manner prescribed by the
          Plan Administrator, to have any portion of an Eligible Rollover
          Distribution that is equal to at least $500 paid directly to an
          Eligible Retirement Plan specified by the Distributee in a Direct
          Rollover.

                           4A. NONDISCRIMINATION TEST

     4A.1 DEFINITIONS.

          (a)  ACTUAL CONTRIBUTION PERCENTAGE. The term Actual Contribution
               Percentage (ACP) means the average of the Actual Contribution
               Ratios of the Eligible Participants in a group.

          (b)  ACTUAL CONTRIBUTION RATIO. The term Actual Contribution Ratio
               means the ratio (expressed as a percentage) of a Participant's
               Contribution Percentage Amounts to that Participant's
               Compensation for the Plan Year (whether or not the Employee was a
               Participant for the entire Plan Year).

          (c)  ACTUAL DEFERRAL PERCENTAGE. The term Actual Deferral Percentage
               (ADP) means the average of the Actual Deferral Ratios for a
               specified group of Participants.

          (d)  ACTUAL DEFERRAL RATIO. The term Actual Deferral Ratio means the
               ratio (expressed as a percentage) of a Participant's Deferral
               Percentage Amounts to that Participant's Compensation for such
               Plan Year. The Actual Deferral Ratio for an Employee who is
               eligible to be a Participant but fails to make Elective Deferral
               Contributions shall be zero.

          (e)  AGGREGATE LIMIT. The term Aggregate Limit means the sum of : (i)
               125 percent of the greater of the ADP of the non-Highly
               Compensated Employees for the Plan Year or the ACP of non-Highly
               Compensated Employees under the plan subject to Code section
               401(m) for the Plan Year beginning with or within the Plan Year
               of the CODA and (ii) the lesser of 200% or two plus the lesser of
               such ADP or ACP. "Lesser" is substituted for "greater" in "(i)",
               above, and "greater" is substituted for "lesser" after "two plus
               the" in "(ii)" if it would result in a larger Aggregate Limit.

          (f)  CONTRIBUTION PERCENTAGE AMOUNTS. The term Contribution Percentage
               Amounts means the sum of the Employee Contributions, Matching
               Contributions, Qualified Matching Contributions (to the extent
               not taken into account for purposes of the ADP test) and
               Qualified Nonelective Contributions (to the extent not taken into
               account for purposes of the ADP test) made under the Plan on
               behalf of the Participant for the Plan Year. Such Contribution
               Percentage Amounts shall not include Matching Contributions that
               are forfeited either to correct Excess Aggregate Contributions or
               because the contributions to which they relate are Excess
               Elective Deferral Contributions, Excess Contributions, or Excess
               Aggregate Contributions. The Employer may elect to use Elective
               Deferrals in the Contribution Percentage Amounts as long as the
               ADP test (as described in Section 4A.2) is met before the
               Elective Deferrals are used in the ACP test (as described in
               Section 4A.4) and the ADP test continues to be met following the
               exclusion of those Elective Deferrals that are used to meet the
               ACP test.

          (g)  DEFERRAL PERCENTAGE AMOUNTS. The term Deferral Percentage
               Amounts means any Elective Deferral Contributions made pursuant
               to the Participant's deferral election, including Excess Elective
               Deferral Contributions of Highly Compensated Employees, but 
               excluding Elective Deferral Contributions that are taken into
               account in the ACP test


Article IV - Legal Limitations        -61-
<PAGE>   70
          (provided the ADP test is satisfied both with and without exclusion of
          these Elective Deferral Contributions). In addition, the Employer may
          choose to make Qualified Nonelective Contributions and Qualified
          Matching Contributions.

     (h)  ELIGIBLE PARTICIPANT. The term Eligible Participant means any Employee
          who is eligible to make an Employee Contribution or Elective Deferral
          Contribution (if the Employer takes such contributions into account in
          the calculation of the Actual Contribution Ratio), or to receive a
          Matching Contribution (including Forfeitures) or a Qualified Matching
          Contribution.  If an Employee Contribution is required as a condition
          of participation in the Plan, any Employee who would be a Participant
          in the Plan if such Employee made the Required Employee Contribution
          shall be treated as an Eligible Participant on behalf of whom no
          Employee Contributions are made.

     If the Employer has elected in its Adoption Agreement to provide for
     Elective Deferral Contributions, then Sections 4A.2 through 4A.5 shall
     apply.

     4A.2 ACTUAL DEFERRAL PERCENTAGE TEST. The ADP for Participants who are
          Highly Compensated Employees for each Plan Year and the ADP for
          Participants who are non-Highly Compensated Employees for the same
          Plan Year must satisfy one of the following tests:

          (a)  The ADP for Participants who are Highly Compensated Employees for
               the Plan Year shall not exceed the ADP for Participants who are
               non-Highly Compensated Employees for the same Plan Year
               multiplied by 1.25; or

          (b)  The ADP for Participants who are Highly Compensated Employees for
               the Plan Year shall not exceed the ADP for Participants who are
               non-Highly Compensated Employees for the same Plan Year
               multiplied by 2.0, provided that the ADP for Participants who are
               Highly Compensated Employees does not exceed the ADP for
               Participants who are non-Highly Compensated Employees by more
               than two (2) percentage points.

     4A.3 SPECIAL RULES - ADP TEST.

          (a)  The ADP for any Participant who is a Highly Compensated Employee
               for the Plan Year and who is eligible to have Elective Deferral
               Contributions (and Qualified Nonelective Contributions or
               Qualified Matching Contributions, or both, if treated as Elective
               Deferrals for purposes of the ADP test) allocated to his accounts
               under two or more CODAs maintained by the Employer, shall be
               determined as if such Elective Deferral Contributions (and, if
               applicable, such Qualified Nonelective Contributions or Qualified
               Matching Contributions, or both) were made under a single CODA.
               If a Highly Compensated Employee participates in two or more
               CODAs that have different Plan Years, such CODAs are treated as a
               single CODA with respect to the Plan Years ending with or within
               the same calendar year.  Notwithstanding the foregoing, certain
               plans shall be treated as separate if mandatorily disaggregated
               under regulations under Code section 401(k).

          (b)  If this Plan satisfies the requirements of Code sections 401(k),
               401(a)(4), or 410(b) only if aggregated with one or more other
               plans, or if one or more other plans satisfy the requirements of
               such Code sections only if


                                      
Article IV - Legal Limitations        -62-
<PAGE>   71
               aggregated with this Plan, then this Section shall be applied by
               determining the ADP of Employees as if all such plans were a
               single plan. For Plan Years beginning after December 31, 1989,
               plans may be aggregated in order to satisfy Code section 401(k)
               only if they have the same Plan Year.

          (c)  If a Highly Compensated Employee is subject to the family
               aggregation rules of section 414(q)(6) because that Participant
               is either a 5-percent owner or one of the top 10 Highly
               Compensated Employees, the combined Actual Deferral Ratio for the
               family group (which is treated as one Highly Compensated
               Employee) must be determined by combining the Elective Deferral
               Contributions (and Qualified Nonelective Contributions or
               Qualified Matching Contributions, or both, if treated as Elective
               Deferral Contributions for purposes of the ADP test), and the
               Compensation for the Plan Year of all the family members (as
               defined in section 414(q)(6)).  Such family members shall be
               disregarded as separate Employees in determining the ADP for both
               Highly Compensated Employees and non-Highly Compensated
               Employees.

          (d)  For purposes of determining the ADP test, Elective Deferral
               Contributions, Qualified Nonelective Contributions and Qualified
               Matching Contributions must be made before the last day of the
               12-month period immediately following the Plan Year to which such
               contributions relate.

          (e)  The Employer shall maintain records sufficient to demonstrate
               satisfaction of the ADP test and the amount of Qualified
               Nonelective Contributions or Qualified Matching Contributions, or
               both, used in such test.

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

          (g)  If the Employer determines before the end of the Plan Year that
               the Plan may not satisfy the ADP test for the Plan Year, the
               Employer may require that the amounts of Elective Deferral
               Contributions being allocated to the accounts of Highly
               Compensated Employees be reduced to the extent necessary to
               prevent Excess Contributions from being made to the Plan.

               Although the Employer may reduce the amounts of Elective Deferral
               Contributions that may be allocated to the Participant's Accounts
               of Highly Compensated Employees, the affected Employees shall
               continue to participate in the Plan. When the situation that
               resulted in the reduction of Elective Deferral Contributions
               ceases to exist, the Employer shall reinstate the amounts of
               Elective Deferral Contributions elected by the affected
               Participants in their Salary Deferral Agreement to the fullest
               extent possible.

     If the employer has elected in its Adoption Agreement, to provide for 
     employee contributions and/or matching contributions required to be tested 
     under code Section 401(m), then Sections 4a.4 and 4a.5 shall apply.

     4A.4 ACTUAL CONTRIBUTION PERCENTAGE TEST. The ACP for Participants who are
          Highly Compensated Employees for each Plan year and the ACP for
          Participants who are non-Highly Compensated Employees for the same
          Plan Year must satisfy one of the following tests:

     Article IV - Legal Limitations          -63-
<PAGE>   72
          (a)  The ACP for Participants who are Highly Compensated Employees
               for the Plan Year shall not exceed the ACP for Participants who
               are non-Highly Compensated Employees for the same Plan Year
               multiplied by 1.25; or

          (b)  The ACP for Participants who are Highly Compensated Employees
               for the Plan Year shall not exceed the ACP for Participants who
               are non-Highly Compensated Employees for the same Plan Year
               multiplied by two (2), provided that the ACP for Participants
               who are Highly Compensated Employees does not exceed the ACP for
               Participants who are non-Highly Compensated Employees by more
               than two (2) percentage points.

     4A.5 SPECIAL RULES - ADP/ACP TESTS.

          (a)  Multiple Use: If one or more Highly Compensated Employees
               participates in both a CODA and a plan subject to the ACP test
               maintained by the Employer, and the sum of the ADP and ACP of
               those Highly Compensated Employees subject to either or both
               tests exceeds the Aggregate Limit, then the ACP of those Highly
               Compensated Employees who also participate in a CODA will be
               reduced (beginning with such Highly Compensated Employee whose
               Actual Contribution Ratio is the highest) so that the limit is
               not exceeded. The amount by which each Highly Compensated
               Employee's Contribution Percentage Amounts are reduced shall be
               treated as an Excess Aggregate Contribution. The ADP and ACP of
               the Highly Compensated Employees are determined after any
               corrections required to meet the ADP and ACP tests. Multiple use
               does not occur if both the ADP and ACP of the Highly Compensated
               Employees does not exceed 1.25 multiplied by the ADP and ACP of
               the non-Highly Compensated Employees.

          (b)  For purposes of this Section, the Actual Contribution Ratio for
               any Participant who is a Highly Compensated Employee and who is
               eligible to have Contribution Percentage Amounts allocated to
               his account under two or more plans described in Code section
               401(a), or CODAs that are maintained by the Employer, shall be
               determined as if the total of such Contribution Percentage
               Amounts was made under each plan. If a Highly Compensated
               Employee participates in two or more CODAs that have different
               Plan Years, all CODAs ending with or within the same calendar
               year are treated as a single CODA. Notwithstanding the
               foregoing, certain plans shall be treated as separate if
               mandatorily disaggregated under regulations under Code section
               401(m).

          (c)  If this Plan satisfies the requirements of Code sections 401(m),
               401(a)(4) or 410(b) only if aggregated with one or more other
               plans, or if one or more other plans satisfy the requirements of
               such sections of the Code only if aggregated with this Plan,
               then this Section shall be applied by determining the Actual
               Contribution Ratio of Employees as if all such plans were a
               single plan. For Plan Years beginning after December 31, 1989,
               plans may be aggregated in order to satisfy Code section 401(m)
               only if they have the same Plan Year.

          (d)  For purposes of determining the Actual Contribution Ratio of a
               Participant who is a 5-percent owner of one of the Top 10 Highly
               Compensated Employees, the Contribution Percentage Amounts and
               Compensation for such Participant shall include the Contribution
               Percentage Amounts and Compensation for the Plan Year of family
               members (as defined in Code

Article IV - Legal Limitations        -64-
                                      
<PAGE>   73
               section 414(q)(6)). Such family members shall be disregarded as
               separate Employees in determining the ACP for Highly Compensated
               Employees and non-Highly Compensated Employees.

          (e)  For purposes of determining the ACP test, Employee Contributions
               are considered to have been made in the Plan Year in which
               contributed to the Plan. Qualified Matching Contributions and
               Qualified Nonelective Contributions are considered made for a
               Plan Year if made no later than the end of the 12-month period
               beginning on the day after the close of the Plan Year.

          (f)  the Employer shall maintain records sufficient to demonstrate
               satisfaction of the ACP test and the amount of Qualified
               Nonelective Contributions or Qualified Matching Contributions, or
               both, used in such test.

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

                         4B. LIMITATIONS ON ALLOCATIONS
          
     4B.1 DEFINITIONS. The following definitions apply for purpose of Section
          4B.

          (a)  ANNUAL ADDITIONS. The term Annual Additions means the sum of the
               following amounts credited to a Participant's Account for the
               Limitation Year:

               (1)  All contributions made by the Employer which shall include:

                    Elective Deferral Contributions;
                    Money Purchase Pension Contributions
                    Matching Contributions;
                    Nonelective Contributions;
                    Qualified Nonelective Contributions;
                    Qualified Matching Contributions;
                    Prior Employer Contributions;

               (2)  Employee Contributions;
     
               (3)  Forfeitures; and

               (4)  Amounts allocated after March 31, 1984 to an individual
                    medical account, as defined in Code section 415(1)(2), which
                    is part of a pension or annuity plan maintained by the
                    Employer, are treated as Annual Additions to a defined
                    contribution plan.  Also, amounts derived from contributions
                    paid or accrued after December 31, 1985 in taxable years
                    ending after such date, which are attributable to
                    post-retirement medical benefits allocated to the separate
                    account of Key Employee as defined in Code section
                    419A(d)(3), under a welfare benefit fund as defined in Code
                    section 419(e), maintained by the Employer, are treated as
                    Annual Additions to a defined contribution plan; and

               (5)  Allocations under a simplified employee pension plan.
     
               For this purpose, any Excess Annual Additions applied under
               Sections 4C.3 or 4B.5(f) in the Limitation Year to reduce
               Employer contributions will be considered Annual Additions for
               such Limitation Year.

<PAGE>   74
          (b)  COMPENSATION. As elected by the Employer in the Adoption
               Agreement, the term Compensation means all of a Participant's:

               (1)  WAGES, TIPS, AND OTHER COMPENSATION BOX ON FORM W-2.
                    (Information required to be reported under Code sections
                    6041, 6051 and 6052). Wages within the meaning of 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 sections 6041(d), 6051(a)(3), and 6052. 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)).

               (2)  SECTION 3401(a) WAGES. Wages as defined in Code section
                    3401(a) for the purposes of 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)).

               (3)  415 SAFE-HARBOR COMPENSATION. 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 maintaining the Plan to the
                    extent that the amounts are includable 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 Code
                    section 1.62-2(c)), and excluding the following:

                    (A)  Employer contributions to a plan of deferred
                         compensation which are not includable in the
                         Employee's gross income for the taxable year in which
                         contributed, or Employer contributions under a
                         simplified employee pension plan to the extent such
                         contributions are deductible by the Employee, or any
                         distributions from a plan of deferred compensation;

                    (B)  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;

                    (C)  Amounts realized from the sale, exchange or other
                         disposition of stock acquired under a qualified stock
                         option; and 

                    (D)  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


Article IV - Legal Limitations        -66-
<PAGE>   75
                    annuity contract described in Code section 403(b) (whether
                    or not the contributions are actually excludable from the
                    gross income of the Employee).

               For any Self-Employed Individual, Compensation means Earned
               Income.

               For Limitation Years beginning after December 31, 1991, for
               purposes of applying the limitations of this Section 4B,
               Compensation for a Limitation Year is the Compensation actually
               paid or includable in gross income 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 and contributions made on
               behalf of such Participant are not nonforfeitable when made.

          (c)  DEFINED BENEFIT FRACTION. The term Defined Benefit Fraction
               means 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).

               Notwithstanding the above, if the Participant was a Participant
               as of the first day of the Limitation Year beginning after
               December 31, 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 such plans which the
               Participant had accrued as of the later of the close of the last
               Limitation Year beginning before January 1, 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 Code section 415 for all Limitation Years
               beginning before January 1, 1987.

               Notwithstanding the foregoing, for any Top-Heavy Plan Year, 100
               shall be substituted for 125 unless the extra minimum allocation
               is being made pursuant to the Employer's election in the Adoption
               Agreement. However, for any Plan Year in which this Plan is a
               Super Top-Heavy Plan, 100 shall be substituted for 125 in any
               event.

          (d)  DEFINED CONTRIBUTION DOLLAR LIMITATION. The term Defined
               Contribution Dollar Limitation means $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.


Article IV - Legal Limitations        -67-
<PAGE>   76
          (e)  DEFINED CONTRIBUTION FRACTION. The term Defined Contribution
               Fraction means a fraction, the numerator of which is the sum of
               the Annual Additions to the Participant's accounts 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 maintained by the
               Employer, and the Annual Additions attributable to all welfare
               benefit funds, as defined in Code section 419(e), individual
               medical accounts, as defined in Code section 415(1)(2), and
               simplified employee pension plans, as defined in Code section 
               408(k), 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 any 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.

               If the Employee was a Participant as of the end of the first day
               of the first Limitation Year beginning after December 31, 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 January 1,
               1987, and disregarding any changes in the terms and conditions of
               the Plan made after May 5, 1986, but using the section 415
               limitation applicable to the first Limitation Year beginning on
               or after January 1, 1987.

               Notwithstanding the foregoing, for any Top-Heavy Plan Year, 100
               shall be substituted for 125 unless the extra minimum allocation
               is being made pursuant to the Employer's election in the Adoption
               Agreement. However, for any Plan Year in which this Plan is a
               Super Top-Heavy Plan, 100 shall be substituted for 125 in any
               event.

               The Annual Additions for any Limitation Year beginning before
               January 1, 1987 shall not be computed to treat all Employee
               Contributions as Annual Additions.

          (f)  EMPLOYER. For purposes of this Section 4B, the term Employer
               means 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)), a group of commonly
               controlled trades or businesses (as defined in Code section
               414(c) as modified by section 415(h)) or affiliated service
               groups (as defined in Code section 414(m)) of which the adopting
               Employer is a part and any other entity required to be aggregated
               with the Employer pursuant to regulations under Code section
               414(o).



Article IV - Legal Limitations        -68-
<PAGE>   77
          (g)  HIGHEST AVERAGE COMPENSATION. The term Highest Average
               Compensation means 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 Section 2A.5.

          (h)  LIMITATION YEAR. The term Limitation Year means a calendar year,
               or the 12-consecutive month period elected by the Employer in the
               Limitation Year section of the Adoption Agreement. 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.

          (i)  MASTER OR PROTOTYPE PLAN. The term Master or Prototype Plan
               means a plan the form of which is subject of a favorable opinion
               letter from the national office of the Internal Revenue Service.

          (j)  MAXIMUM PERMISSIBLE AMOUNT. The term Maximum Permissible Amount
               means the maximum Annual Additions that may be contributed or
               allocated to a Participant's Account under the Plan for any
               Limitation Year, which shall not exceed the lesser of:

               (1)  The Defined Contribution Dollar Limitation, or

               (2)  25 percent of the Participant's Compensation for the
                    Limitation Year.

               The Compensation limitation referred to in (2) above, shall not
               apply to any contribution for medical benefits (within the
               meaning of Code section 401(h) or 419(A)(f)(2)) which is
               otherwise treated as Annual Additions under Code sections
               415(l)(1) or 419A(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
                 ---------------------------------------------
                                       12

          (k)  PROJECTED ANNUAL BENEFIT. The term Projected Annual Benefit
               means the annual retirement benefit (adjusted to an actuarially
               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 the Plan assuming:

               (1)  The Participant will continue employment until Normal
                    Retirement Age under the Plan (or current age, if later); 
                    and

               (2)  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.

     4B.2 BASIC LIMITATION. If the Participant does not participate in, and has
          never participated in another qualified plan or welfare benefit fund
          maintained by the Employer, as defined in Code section 419(e), or an
          individual medical account, as defined in Code section 415(l)(2),
          maintained by the Employer, or a simplified



ARTICLE IV - Legal Limitations       -69-

          employee pension, as defined in Code section 408(k), maintained by
          the Employer, which provides Annual Additions as defined in Section
          4B.1(a), 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 contributions 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.

     4B.3 ESTIMATED 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.

     4B.4 ACTUAL MAXIMUM PERMISSIBLE AMOUNT. 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.

     4B.5 PARTICIPANTS COVERED BY ANOTHER PROTOTYPE DEFINED CONTRIBUTION PLAN.

          (a)  This Section applies if, in addition to this Plan, the
               Participant is covered under another qualified Master or
               Prototype defined contribution Plan maintained by the Employer,
               or a welfare benefit fund, as defined in Code section 419(e),
               maintained by the Employer, or an individual medical account as
               defined in Code section 415(1)(2), maintained by the Employer,
               or a simplified employee pension plan, as defined in Code
               section 408(k), that provides Annual Additions as defined in
               Section 4B.1(a), during any Limitation Year. The Annual
               Additions which may be credited to a Participant's Account under
               this Plan for any such Limitation Year will not exceed the
               Maximum Permissible Amount reduced by the Annual Additions
               credited to a Participant's account under the other qualified
               Master and Prototype defined contribution Plans, welfare benefit
               funds, individual medical accounts, and simplified employee
               pension plans for the same Limitation Year. If the Annual
               Additions with respect to the Participant under other qualified
               Master and Prototype defined contribution Plans, welfare benefit
               funds, individual medical accounts, and simplified employee
               pension plans maintained by the Employer are less than the
               Maximum Permissible Amount and the Employer contributions 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
               qualified master and prototype defined contribution plans,
               welfare benefit funds, individual medical accounts, and
               simplified employee pension plans, 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.

Article IV - Legal Limitations        -70-
                                      
          
<PAGE>   79
          (b)  Prior to determining the Participant's actual Compensation for
               the Limitation Year, the Employer may determine the estimated
               Maximum Permissible Amount for a Participant in the manner
               described in Section 4B.3.

          (c)  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.

          (d)  If, pursuant to Section 4B.5(c), or as a result of the
               allocation of Forfeitures, a Participant's Annual Additions
               under this Plan and other such plans would result in Excess
               Annual Additions as defined in Section 4C.1(b) for a Limitation
               Year, the Excess Annual Additions will be deemed to consist of
               the Annual Additions last allocated, except that Annual Additions
               attributable to a simplified employee pension plan will be
               deemed to have been allocated first, followed by Annual Additions
               to a welfare benefit fund or individual medical account, 
               regardless of the actual allocation date.

          (e)  If Excess Annual Additions were allocated to a Participant on an
               allocation date of this Plan which coincides with an allocation
               date of another plan, the Excess Annual Additions attributed to
               this Plan will be the product of:

               (1)  The total Excess Annual Additions allocated as of such date
                    multiplied by

               (2)  The ratio of (i) the Annual Additions allocated to the
                    Participant for the Limitation Year as of such date under
                    this Plan to (ii) the total Annual Additions allocated to
                    the Participant for the Limitation Year as of such date
                    under this and all other qualified Master or Prototype
                    defined contribution Plans.

          (f)  Any Excess Annual Additions attributed to this Plan will be
               disposed of in the manner described in Section 4C.3.

     4B.6 PARTICIPANTS COVERED BY NON-PROTOTYPE DEFINED CONTRIBUTION 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 Section 4B.5 as though the other plan were
          a Master or Prototype Plan, unless the Employer provides other
          limitations in the Limitations on Allocations section of the Adoption
          Agreement.

     4B.7 PARTICIPANTS COVERED BY DEFINED BENEFIT PLAN. If the Employer
          maintains, or at any time maintained, a qualified defined benefit plan
          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. 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
          Limitations on Allocations section of the Adoption Agreement.

                           4C. TREATMENT OF EXCESSES


     4C.1 DEFINITIONS.

          (a)  EXCESS AGGREGATE CONTRIBUTIONS. The term Excess Aggregate
               Contributions means, with respect to any Plan Year, the excess 
               of:

               (1)  The aggregate Contribution Percentage Amounts taken into
                    account in computing the ACP of Highly Compensated Employees
                    for such Plan Year, over

               (2)  The maximum Contribution Percentage Amounts permitted by the
                    ACP test (determined by reducing the Contribution Percentage
                    Amounts made on behalf of Highly Compensated Employees in
                    order of their Actual Contribution Ratios beginning with the
                    highest of such ratios). Such determination shall be made
                    after first determining Excess Elective Deferral
                    Contributions, pursuant to Section 4C.2(a) and then
                    determining Excess Contributions pursuant to Section 4C.4.

          (b)  EXCESS ANNUAL ADDITIONS. The term Excess Annual Additions means
               the excess of the Participant's Annual Additions for the
               Limitation Year over the Maximum Permissible Amount.

          (c)  EXCESS CONTRIBUTIONS. The term Excess Contributions means, with
               respect to any Plan Year, the excess of:

               (1)  The aggregate Deferral Percentage Amounts taken into account
                    in computing the ADP of Highly Compensated Employees for
                    such Plan Year, over

               (2)  The maximum Deferral Percentage Amounts permitted by the ADP
                    test (determined by reducing the Deferral Percentage Amounts
                    made on behalf of Highly Compensated Employees in order of
                    their Actual Deferral Ratios, beginning with the highest of
                    such ratios).

          (d)  EXCESS ELECTIVE DEFERRAL CONTRIBUTIONS. The term Excess Elective
               Deferral Contributions means those Elective Deferral
               Contributions that are includable in a Participant's gross income
               under Code section 402(g) to the extent such Participant's
               Elective Deferral Contributions for a taxable year exceed the
               dollar limitation under such Code section. Excess Elective
               Deferral Contributions shall be treated as Annual Additions under
               the Plan pursuant to Section 4B, unless such amounts are
               distributed in accordance with the provisions of Section 4C.2(a),
               below.

     4C.2 EXCESS ELECTIVE DEFERRAL CONTRIBUTIONS.
     
          (a)  In the event that Elective Deferral Contributions made during a
               calendar year exceed the limit specified in Section 2C.1(j)(4),
               then the Excess Elective Deferral Contributions, plus any income
               and minus any loss allocable thereto, shall be distributed to the
               Participant by the April 15 following the calendar year in which
               such amount was contributed, provided that the Participant
               notifies the Plan Administrator no later than 30 days in advance
               of his intent to withdraw such Excess Elective Deferral
               Contributions, or is deemed to notify the Plan Administrator. A
               Participant is deemed to notify the Plan Administrator of any
               Excess Elective Deferral Contributions that arise by taking into
               account only


Article IV - Legal Limitations        -72-
<PAGE>   81
               those Elective Deferrals made to this Plan and any other plans of
               this Employer. The spousal consent provisions of Section 3C shall
               not apply to any distribution of Excess Elective Deferral
               Contributions.

          (b)  Excess Elective Deferral Contributions shall be adjusted for any
               income or loss for the Employee's tax year. The income or loss
               allocable to excess Elective Deferral Contributions is an amount
               determined by multiplying the sum of the income or loss allocable
               to the Participant's Elective Deferral Contribution account for
               the taxable year by a fraction, the numerator of which is such
               Participant's Excess Elective Deferral Contributions for the
               taxable year, and the denominator of which is equal to the sum of
               the Participant's Account balance attributable to Elective
               Deferral Contributions as of the beginning of the taxable year
               plus the Participant's Elective Deferral Contributions for the
               taxable year. Income for the gap period (the period from the end
               of the taxable year to the date of distribution) shall not be
               allocated to Excess Elective Deferral Contributions.

          (c)  Matching Contributions, as defined in Section 1.35, that are
               attributable to Excess Elective Deferral Contributions shall be
               forfeited, and as such, shall be applied to reduce Employer
               contributions or pay Plan expense.

     4C.3 EXCESS ANNUAL ADDITIONS. If, pursuant to Section 4B.4 or as a result
          of the allocation of Forfeitures, there are Excess Annual Additions,
          the excess will be disposed of using any of the following methods:

          (a)  Employee Contributions or Elective Deferral Contributions or
               both, to the extent they would reduce the Excess Annual
               Additions, will be returned to the Participant. The Contributions
               returned in accordance with the preceding shall include any gains
               or losses attributable to such Contributions.

               Employee Contributions so returned will be disregarded with
               respect to the ACP test. Elective Deferral Contributions so
               returned will be disregarded with respect to the Elective
               Deferral limitation described in Section 2C.1(j)(4) of the Plan
               and the ADP test.

          (b)  If, after the application of paragraph (a), Excess Annual
               Additions still exist and the Participant is covered by the Plan
               at the end of the Limitation Year, the Excess Annual Additions in
               the Participant's Account, other than Employee Contributions and
               Elective Deferral Contributions, 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.

          (c)  If, after the application of paragraph (a), Excess Annual
               Additions still exist and the Participant is not covered by the
               Plan at the end of a Limitation Year, the Excess Annual Additions
               will be held unallocated in a suspense account. The suspense
               account will be applied to reduce future Employer contributions
               (including allocation of any Forfeiture) for all remaining
               Participants in the next Limitation Year, and each succeeding
               Limitation Year if necessary.

          (d)  If a suspense account is in existence at any time during the
               Limitation Year pursuant to this Section, it will not participate
               in the allocation of the Trust or Insurance Company's gains and 
               losses. If a suspense account is in


Article IV - Legal Limitations        -73-
<PAGE>   82
               existence at any time during a particular Limitation Year, all
               amounts in the suspense account must be allocated and reallocated
               to the Participants' Account before any Employer or Employee
               Contributions may be made to the Plan for that Limitation Year.
               Except as provided in Section 4C.3(a), Excess Annual Additions
               may not be distributed to Participants or former Participants.

     4C.4 EXCESS CONTRIBUTIONS.

          (a)  Notwithstanding any other provision of this Plan, Excess
               Contributions, plus any income and minus any loss allocable
               thereto, shall be distributed no later than the last day of each
               Plan Year to Participants to whose Participants' Accounts such
               Excess Contributions were allocated for the preceding Plan Year.
               If such excess amounts are distributed more than 2-1/2 months
               after the last day of the Plan Year in which such excess amounts
               arose, a ten percent excise tax will be imposed on the Employer
               maintaining the Plan with respect to such amounts.

               Such distributions shall be made to Highly Compensated Employees
               on the basis of the respective portions of the Excess
               Contributions attributable to each of such Employees.

               The distribution of Excess Contributions made to the family
               members of a family group that was combined for purposes of
               determining a Highly Compensated Employee's Actual Deferral Ratio
               shall be allocated among the family members in proportion to the
               Deferral Percentage Amounts (including any amounts required to be
               taken into account under Sections 4A.3(a) and (b) of the Plan) of
               each family member that is combined to determine the Actual
               Deferral Ratio.

          (b)  Excess Contributions shall be treated as Annual Additions, as
               defined in Section 4B.1, under the Plan in the Limitation Year in
               which they arose.

          (c)  Excess Contributions shall be adjusted for any income or loss for
               the Plan Year. The income or loss allocable to Excess
               Contributions is an amount determined by multiplying the sum of
               the income or loss allocable to the Participant's Account for
               Deferral Percentage Amounts for the Plan Year, by a fraction, the
               numerator of which is such Participant's Excess Contributions for
               the Plan Year and the denominator of which is equal to the sum of
               the Participant's Account balance attributable to Deferral
               Percentage Amounts as of the beginning of the Plan Year plus the
               Participant's Deferral Percentage Amounts for the Plan Year.
               Income for the gap period (the period from the end of the Plan
               Year to the date of distribution) shall not be allocated to
               Excess Contributions.

          (d)  Excess Contributions shall be distributed from the Participant's
               Account for Elective Contributions and Qualified Matching
               Contributions (if applicable) in proportion to the Participant's
               Elective Deferral Contributions and Qualified Matching
               Contributions (to the extent used in the ADP test) for the Plan
               Year. Excess Contributions shall be distributed from the
               Participant's Qualified Nonelective Contribution Account only to
               the extent that such Excess Contributions exceed the balance in
               the Participant's Account for Elective Contributions and
               Qualified Matching Contributions.



Article IV - Legal Limitations        -74-
<PAGE>   83
          (e)  Matching Contributions, as defined in Section 1.35, that are
               attributable to Excess Contributions, shall be forfeited, and as
               such, shall be applied to reduce Employer contributions or pay
               Plan expenses.

     4C.5 EXCESS AGGREGATE CONTRIBUTIONS.

          (a)  Notwithstanding any other provision of this Plan, Excess
               Aggregate Contributions, plus any income and minus any loss
               allocable thereto, shall be forfeited, if forfeitable, or if not
               forfeitable, distributed no later than the last day of each Plan
               Year to Participants to whose Participants' Accounts such Excess
               Aggregate Contributions were allocated for the preceding Plan
               Year.  If such Excess Aggregate Contributions are distributed
               more than 2-1/2 months after the last day of the Plan Year in
               which such excess amounts arose, a ten percent excise tax will be
               imposed on the Employer maintaining the Plan with respect to
               those amounts.

               The distribution of Excess Aggregate Contributions made to the
               family members of a family group that was combined for purposes
               of determining a Highly Compensated Employee's Actual
               Contribution Ratio shall be allocated among the family members
               in proportion to the Contribution Percentage Amounts (including
               any amounts required to be taken into account under Sections
               4A.5(a) and (b) of the Plan) of each family member that is
               combined to determine the Actual Contribution Ratio.
          
          (b)  Excess Aggregate Contributions shall be treated as Annual
               Additions, as defined in Section 4B.1, in the Limitation Year in
               which they arose.

          (c)  Excess Aggregate Contributions shall be adjusted for any income
               or loss for the Plan Year. The income or loss allocable to Excess
               Aggregate Contributions is an amount determined by multiplying
               the sum of the income or loss allocable to the Participant's
               Account for Contribution Percentage Amounts for the Plan Year by
               a fraction, the numerator of which is such Participant's Excess
               Aggregate Contributions for the Plan Year, and the denominator of
               which is equal to the sum of the Participant's Account balance
               attributable to Contribution Percentage Amounts as of the
               beginning of the Plan Year plus the Participant's Contribution
               Percentage Amounts for the Plan Year. Income for the gap period
               (the period from the end of the Plan Year to the date of
               distribution) shall not be allocated to Excess Aggregate
               Contributions.

          (d)  Excess Aggregate Contributions shall be forfeited, if
               forfeitable, or distributed on a pro-rata basis from the
               Participant's Account for Employee Contributions, Matching
               Contributions, and Qualified Matching Contributions (and, if
               applicable, the Participant's Qualified Nonelective Contributions
               or Elective Deferral Contributions, or both).

          (e)  Forfeitures of Excess Aggregate Contributions shall be applied to
               reduce Employer contributions or pay Plan expenses.

          (f)  Matching Contributions as defined in Section 1.35 that are
               attributable to Excess Aggregate Contributions shall be
               forfeited, and as such, shall be applied to reduce Employer
               contributions or pay Plan expenses.

                 5A. ANNUITY CONTRACT AND PARTICIPANT'S ACCOUNT

     5A.1 PARTICIPANT'S ACCOUNT. A Participant's Account shall be maintained on
          behalf of each Participant until such Account is distributed in
          accordance with the terms of this Plan.

          Each Participant shall have the exclusive authority to direct the
          investment of Employee Contributions, Elective Deferral Contributions,
          QVEC Contributions and Rollover Contributions, if applicable, from
          among the investment options selected by the Employer.

          If selected by the Employer in its Adoption Agreement, the
          Participant, Beneficiary and/or Alternate Payee additionally shall
          have the exclusive authority to direct the investment of contributions
          made by the Employer from among the investment choices selected by the
          Employer.

     5A.2 INVESTMENT TRANSFERS. Each Participant, Beneficiary, and/or Alternate
          Payee shall have the exclusive authority to direct the transfer of
          amounts between the investment funds designated by the Employer,
          attributable to his Employee Contributions, Elective Deferral
          Contributions, QVEC Contributions and Rollover Contributions, if
          applicable.

          If the Employer selects in its Adoption Agreement to grant the
          Participant exclusive authority to direct the investment of
          contributions made by the Employer, the Participant, Beneficiary,
          and/or Alternate Payee shall also have the exclusive authority to
          transfer contributions made by the Employer from among the investment
          choices selected by the Employer.

          The transfer of amounts between investment funds shall be subject to
          the rules of the investment funds in which the Participant's Account
          is invested or is to be invested.

          The Plan Administrator or the Participant, Beneficiary, and/or
          Alternate Payee as the case may be, may change such amounts as often
          as the Plan Administrator may allow in accordance with the terms of
          the investment funds in which the Participant's Account is being
          invested.

          The ability of a Participant who is subject to the reporting
          requirements of section 16(a) of the Securities an Exchange Act of
          1934 (the "Act") to make withdrawals or investment changes involving
          the Participant's Employer Stock Account may be restricted by the Plan
          Administrator to comply with rules under section 16(b) of the Act.

     5A.3 PARTICIPANT'S ACCOUNT VALUATION. A Participant's Account shall be
          maintained on behalf of each Participant until such Account is
          distributed in accordance with the terms of this Plan. At least once
          per year, as of the last day of the Plan Year, each Participant's
          Account shall be adjusted, in the ratio that the Participant's Account
          balance bears to all account balances invested into the same
          investment vehicle, for any earnings, gains, losses, contributions,
          withdrawals, expenses, and loans attributable to such Plan Year, in
          order to obtain a new valuation of the Participant's Account. The
          assets of the Plan will be valued annually at fair market value as of
          the last day of each Plan Year.

                          5B. LIFE INSURANCE POLICIES

     5B.1 OPTIONAL PURCHASE OF LIFE INSURANCE.  If the Employer in its Adoption
          Agreement shall permit the purchase of life insurance on the lives of
          some or all Participants hereunder, each eligible Participant may
          elect that a portion of the Contribution made on his behalf shall be
          applied to the purchase of a Life Insurance Policy or Policies on his
          life. The application for each Policy shall be signed by the
          Participant and by the Trustee and shall conform to the requirements
          of the Insurance Company, including any requested evidence of
          insurability, and the requirements of this Section.  All Life
          Insurance Policies shall be issued so as to permit a common billing
          date.  Any Policy on the life of a Participant who can qualify for
          waiver of premium thereunder and participant account contribution
          disability benefits thereunder may include such benefits if applied
          for by the Participant.  The Plan Administrator may adopt reasonable
          rules regarding the purchase of Life Insurance Policies provided such
          rules are administered in a consistent and nondiscriminatory manner.
          No application shall be made hereunder for any Life Insurance Policy
          on the life of a Participant acceptable to the Insurance Company at
          standard premium rates for a face amount of less that $1,000 for the
          first, or any additional Policy issued on the Participant's life. 

     5B.2 PREMIUMS ON LIFE INSURANCE POLICIES.  The premiums on all Life
          Insurance Policies on the life of a Participant shall be paid from the
          portion of his Participant's Account attributable to contributions
          made by the Employer, to the extent sufficient therefor, otherwise in
          one of the following manners:

          (a)  By a loan against the Participant's Policy or Policies, under the
               automatic premium loan provisions thereof, or                

          (b)  By payment out of his Participant's Account.

          If the Participant is not acceptable to the Insurance Company as a
          standard risk at standard rates, a Policy with the same premium but a
          lesser death benefit may be purchased.

     5B.3 LIMITATIONS ON PREMIUMS.  In no case shall the cumulative total
          premiums paid on all Policies held on the life of a Participant
          hereunder exceed an amount equal to the applicable percentage set
          forth below of all Contributions (other than Employee Contributions)
          and Forfeitures theretofore allocated or currently due on his behalf:

          (a)  49% in the case of ordinary life insurance or similar policies.

          (b)  25% in the case of term insurance policies or a combination of
               policies, with premiums on ordinary life insurance or similar
               policies being given half weight.

          If such cumulative total premiums would otherwise exceed this amount,
          the necessary steps to avoid this result shall be taken by reduction
          of the Participant's life insurance coverage by changing all or a
          portion of his coverage to paid-up life insurance or by selling the
          excess portion to the Participant.

     5B.4 DISPOSAL. A Participant who no longer wishes to have any part of
          his allocable share of Contributions used to pay the premiums for any
          Life Insurance Policy or Policies may withdraw a prior election by
          written notice to the Trustee to that


Article V - Participant Provisions    -77-




          
<PAGE>   86
          effect. Any Policy shall be disposed of in accordance with its
          provisions as the Trustee shall direct.

    5B.5  RIGHTS UNDER POLICIES. Each Policy shall provide that the Trustee
          shall have the right to receive any or all payments that may be due
          during the Participant's  lifetime. Any death benefit shall be
          payable directly to the Beneficiary named in the Policy and the
          Participant shall have the right, subject to the terms of Section 3C,
          either directly or through the Trustee, to change the Beneficiary
          from time to time and to elect settlement options under the policy
          for the benefit of the Beneficiary. The Trustee shall have the right
          to exercise all other options and privileges contained in the policy
          and shall exercise such rights and privileges in a manner consistent
          with the terms of the Plan.

    5B.6  LOANS. No loans shall be made against any of the Policies hereunder
          either from the Insurance Company or any other source unless such
          loans are made in order to pay amounts then due as premiums thereon.

    5B.7  CONDITIONS OF COVERAGE. Except as may be otherwise provided in any
          conditional or binding receipt issued by the Insurance Company, there
          shall be no coverage and no death benefit payable under any Policy to
          be purchased from the Insurance Company until such Policy shall have
          been delivered and the premium therefor shall have been paid to the
          Insurance Company as a premium for that Policy. Neither the Employer
          nor the Trustee shall have any responsibility as to the effectiveness
          of any Life Insurance Policy purchased from the Insurance Company
          hereunder nor be under any liability or obligation to pay any amount
          to any Participant or his Beneficiary by reason of any failure or
          refusal by the Insurance Company to make such payment.

    5B.8  POLICY NOT YET IN FORCE. If at the death of any Participant, the
          Trustee shall be holding any amount intended for the purchase of any
          Life Insurance Policy on the Participant's life, but coverage under
          such Policy shall not yet be in force, the Trustee shall credit such
          amount to the Participant's Account to be disposed of as a portion
          thereof.

    5B.9  VALUE OF POLICY. The value of any Policy on the life of a living
          Participant for any purpose under this Plan shall be that amount which
          the Insurance Company would pay upon surrender of such Policy in
          accordance with its usual rules and practices.

    5B.10 DIVIDENDS. If dividends are allowed on any Life Insurance Policy,
          they shall be used to provide additional benefits under the Policy.

    5B.11 DISTRIBUTION. No life insurance protection shall continue in force
          under the Plan subsequent to a Participant's retirement or Termination
          of Employment, whichever occurs first. As of such date, any Life
          Insurance Policy shall be distributed to the Participant in accordance
          with its terms and the terms of Section 3C.3.

    5B.12 APPLICATION. The Trustee, if the Plan is trusteed, or custodian, if
          the Plan has a custodial account, shall apply for and will be the
          owner of any Life Insurance Policy purchased under the terms of this
          Plan. The Life Insurance Policy(ies) must provide that proceeds will
          be payable to the Trustee (or custodian, if applicable). However, the
          Trustee (or custodian) shall be required to pay over all proceeds of
          the Life Insurance Policy(ies) to the Participant's designated
          Beneficiary in accordance with the distribution provisions of this
          Plan. A Participant's Spouse will be the designated Beneficiary of the
          proceeds in all circumstances unless a

Article V - Participant Provisions    -78-
<PAGE>   87
          Qualified Election has been made in accordance with Section 3C.2(c),
          Joint and Survivor Annuity Requirements, if applicable. Under no
          circumstances shall the Trust (or custodial account) retain any part
          of the proceeds.

          In the event of any conflict between the provisions of this Plan and
          any Life Insurance Policies or annuity contracts issued pursuant to
          the Plan, the Plan provisions shall control.

                                   5C. LOANS

     5C.1 LOANS TO PARTICIPANTS. If the Employer has specified in its Adoption
          Agreement that loans are permitted, then the Plan Administrator may
          make a bona fide loan to a Participant, in an amount which, when
          added to the outstanding balance of all other loans to the
          Participant from all qualified plans of the Employer, does not exceed
          the lesser of $50,000 reduced by the excess of the Participant's
          highest outstanding loan balance during the 12 months preceding the
          date on which the loan is made over the outstanding loan balance on
          the date the new loan is made, or 50% of the Participant's Vested
          Interest in his Participant's Account excluding amounts attributable
          to QVEC Contributions. Notwithstanding any provision in this
          paragraph to the contrary, loans may not exceed a Participant's
          Vested Interest attributable to such contributions.

          In the event of default, foreclosure on the note and attachment of
          security will not occur until a distributable event occurs in the
          Plan.

          No loans will be made to any Shareholder-Employee or Owner-Employee
          or to family members of Shareholder-Employees or Owner-Employees, as
          defined in Code section 267(c)(4).

          The loan shall be made under such terms, security interest, and
          conditions as the Plan Administrator deems appropriate, provided,
          however, that:

          (a)  Loans shall be made available to all Participants and
               parties-in-interest (as defined in ERISA and including Employees
               and Beneficiaries), on a reasonably equivalent basis.

          (b)  Loans shall not be made available to Highly Compensated
               Employees on a basis greater than the basis made available to
               other Employees.

          (c)  Loans must bear a reasonable rate of interest.

          (d)  Loans are adequately secured.

          (e)  Unless the provisions of Section 3C.6 apply to a Participant,
               loans may be made only after a Participant obtains the consent
               of his Spouse, if any, to use his Participant's Account as
               security for the loan.  Spousal consent shall be obtained no
               earlier than the beginning of the 90-day period that ends on the
               date on which the loan is to be so secured. The consent must be
               in writing, 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 with respect to that loan. A new
               consent shall be required if the Participant's Account is used
               for renegotiation, extension, renewal or other revision of the
               loan.

          (f)  Loans must be made in accordance with and subject to all of the
               provisions of this Section 5C.

Article V - Participant Provisions    -79-
                                      

<PAGE>   88
     If a valid spousal consent has been obtained in accordance with (e), then,
     notwithstanding any other provision of this Plan, the portion of the
     Participant's Vested Interest used as a security interest held by the Plan
     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 Interest in his Participant's Account (determined without regard to
     the preceding sentence) is payable to the surviving Spouse, then the
     Participant's Account shall be adjusted by first reducing the Vested
     Interest by the amount of the security used as repayment of the loan, and
     then determining the benefit payable to the surviving Spouse.

5C.2 LOAN PROCEDURES. The Plan Administrator shall establish a written set of
     procedures, set forth in the summary plan description or any other
     established set of procedures, which becomes a part of such Plan by which
     all loans will be administered. Such rules, which are incorporated herein
     by reference, will include, but not be limited to the following:

     (a)  The person or persons authorized to administer the loan program,
          identified by name or position;

     (b)  The loan application procedure;

     (c)  The basis for approving or denying loans;

     (d)  Any limits on the types of loans permitted;

     (e)  The procedure for determining a "reasonable" interest rate;

     (f)  Acceptable collateral;

     (g)  Default conditions; and

     (h)  Steps which will be taken to preserve Plan assets in the event of
          default.

                            5D. PARTICIPANT'S RIGHTS

5D.1 GENERAL RIGHTS OF PARTICIPANTS AND BENEFICIARIES. The Plan is established
     and the Plan or Trust assets are held for the exclusive purpose of
     providing benefits for such Employees and their Beneficiaries as have
     qualified to participate under the terms of the Plan.

5D.2 FILING A CLAIM FOR BENEFITS. A Participant or Beneficiary, or the Employer
     acting in his behalf, shall notify the Plan Administrator of a claim of
     benefits under the Plan. Such request shall be in writing to the Plan
     Administrator and shall set forth the basis of such claim and shall
     authorize the Plan Administrator to conduct such examinations as may be
     necessary to determine the validity of the claim and to take such steps as
     may be necessary to facilitate the payment of any benefits to which the
     Participant or Beneficiary may be entitled under the terms of the Plan.

5D.3 DENIAL OF CLAIM. Whenever a claim for benefits by any Participant or
     Beneficiary has been denied by a Plan Administrator, a written notice,
     prepared in a manner calculated to be understood by the Participant, must
     be provided, setting forth (1) the specific reasons for the denial; (2) the
     specific reference to pertinent Plan provisions on which the denial is
     based; (3) a description of any additional material or information
     necessary for the claimant to perfect the claim



Article V - Participant Provisions      -80-
<PAGE>   89
          and an explanation of why such material or information is necessary;
          and (4) an explanation of the Plan's claim review procedure.

     5D.4 REMEDIES AVAILABLE TO PARTICIPANTS. A Participant or Beneficiary (1)
          may request a review by a Named Fiduciary, other than the Plan
          Administrator, upon written application to the Plan; (2) may review
          pertinent Plan documents; and (3) may submit issues and comments in
          writing to a named Fiduciary. A Participant or Beneficiary shall have
          60 days after receipt by the claimant of written notification of a
          denial of a claim to request a review of a denied claim.

          A decision by a Named Fiduciary shall be made promptly and not later
          than 60 days after the Named Fiduciary's receipt of a request for
          review, unless special circumstances require an extension of the time
          for processing in which case a decision shall be rendered as soon as
          possible, but not later than 120 days after receipt of a request for
          review. The decision on review by a Named Fiduciary shall be in
          writing and shall include specific reasons for the decision, written
          in a manner calculated to be understood by the claimant, and specific
          references to the pertinent Plan provisions on which the decision is
          based.

          A Participant or Beneficiary shall be entitled, either in his own name
          or in conjunction with any other interested parties, to bring such
          actions in law or equity or to undertake such administrative actions
          or to seek such relief as may be necessary or appropriate to compel
          the disclosure of any required information, to enforce or protect his
          rights, to recover present benefits due to him or to clarify his
          rights to future benefits under the Plan.

     5D.5 LIMITATION OF RIGHTS. Participation hereunder shall not grant any
          Participant the right to be retained in the Service of the Employer or
          any other rights or interest in the Plan or Trust Fund other than
          those specifically herein set forth.

     5D.6 100% VESTED CONTRIBUTIONS. Each Participant, regardless of his length
          of Service with the Employer, shall be fully vested (100%) at all
          times in any portion of his Participant's Account attributable to the
          following contributions, as applicable:

          (a)  Employee Contributions and earnings thereon;

          (b)  Elective Deferral Contributions and earnings thereon;

          (c)  Qualified Matching Contributions and earnings thereon;

          (d)  Qualified Nonelective Contributions and earnings thereon;

          (e)  Rollover Contributions and earnings thereon;

          (f)  QVEC Contributions and earnings thereon.

     5D.7 REINSTATEMENT OF BENEFIT. In the event any portion of a benefit which
          is payable to a Participant or a Beneficiary shall remain unpaid on
          account of the inability of the Plan Administrator, after diligent
          effort, to locate such Participant or Beneficiary, the amount so
          distributable shall be treated as a Forfeiture under Section 3D. If a
          claim is made by the Participant or Beneficiary for any benefit
          forfeited under this Section, such benefit must be reinstated by the
          Employer.

     Article V - Participant Provisions     -81-
<PAGE>   90
     5D.8 NON-ALIENATION. It is a condition of the Plan, and all rights of each
          Participant shall be subject thereto, that no right or interest of any
          Participant in the Plan shall be assignable or transferable in whole
          or in part, either directly or by operation of law or otherwise,
          including, but without limitation, execution, levy, garnishment,
          attachment, pledge, bankruptcy or in any other manner, and no right or
          interest of any Participant in the Plan shall be liable for or subject
          to any obligation or liability of such Participant. The preceding
          sentence shall not preclude the enforcement of a federal tax levy made
          pursuant to Code section 6331 or the collection by the United States
          on a judgement resulting from an unpaid tax assessment.

          The preceding paragraph 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 QDRO. A domestic relations order entered before
          January 1, 1985 will be treated as a QDRO if payment of benefits
          pursuant to the order has commenced as of such date, and may be
          treated as a QDRO if payment of benefits has not commenced as of such
          date, even though the order does not satisfy the requirements of Code
          section 414(p).

     discharge his duties hereunder solely in the interest of the Participants
     and their Beneficiaries and for the exclusive purpose of providing benefits
     to Participants and their Beneficiaries and defraying reasonable expenses
     of administering the Plan. Each Fiduciary shall act with the care, skill,
     prudence and diligence under the circumstances that a prudent man acting in
     a like capacity and familiar with such matters would use in conducting an
     enterprise of like character and with like aims, in accordance with
     documents and instruments governing this Plan, insofar as such documents
     and instruments are consistent with this standard.

     more than one Fiduciary capacity with respect to this Plan, specifically
     including service both as Trustee and Plan Administrator.

6A.3 LIMITATIONS ON FIDUCIARY LIABILITY. Nothing in this Plan shall be construed
     to prevent any Fiduciary from receiving any benefit to which he may be
     entitled as a Participant or Beneficiary in this Plan, so long as the
     benefit is computed and paid on a basis which is consistent with the terms
     of this Plan as applied to all other Participants and Beneficiaries. Nor
     shall this Plan be interpreted to prevent any Fiduciary from receiving any
     reasonable compensation for services rendered, or for the reimbursement of
     expenses properly and actually incurred in the performance of his duties
     with the Plan; except that no Person so serving who already receives
     full-time pay from an Employer shall receive compensation from this Plan,
     except for reimbursement of expenses properly and actually incurred.

6A.4 INVESTMENT MANAGER. If an Investment Manager has been appointed pursuant to
     Section 6B.7 of this Plan, he is required to acknowledge in writing that he

          The Plan Administrator shall comply with the regulatory provisions of
          ERISA and shall furnish to each Participant (a) a summary plan
          description, (b) upon written request, a statement of his total
          benefits accrued and his vested benefits if any and (c) the
          information necessary to elect the benefits available under the Plan.
          The Plan Administrator shall also file the appropriate annual reports
          and any other data which may be required by appropriate regulatory
          agencies.

          Furthermore, the Plan Administrator shall take the necessary steps to
          notify the appropriate interested parties whenever an application is
          made to the Secretary of the Treasury for a determination letter in
          accordance with Code section 7476 as amended.

     6B.3 SPECIAL DUTIES. If the Employer that adopts this Plan is not the Plan
          Administrator, and the Plan provides for either Employee
          Contributions or Matching Contributions to be made, the Plan
          Administrator shall:

          (a)  Maintain records that enable it to monitor the adopting
               Employer's compliance with the requirements of Code section
               401(m);

          (b)  Perform the ACP test, as described in Section 4A.4, for the
               Employer on an annual basis; and

               Aggregate Contributions.

     6B.4 EXPENSES AND COMPENSATION. The expenses necessary to administer the
          Plan shall be taken from Participants' Accounts unless paid by the
          Employer, including but not limited to those involved in retaining
          necessary professional assistance from an attorney, an accountant, an
          actuary, or an investment advisor. Nothing shall prevent the Plan
          Administrator from receiving reasonable compensation for services
          rendered in administering this Plan, provided the Plan Administrator
          is not a full-time Employee of any Employer adopting this Plan.

     6B.5 INFORMATION FROM EMPLOYER. To enable the Plan Administrator to
          perform his functions, the Employer shall supply full and timely
          information to the Plan Administrator on all matters relating to this
          Plan as the Plan Administrator may require.

     6B.6 ADMINISTRATIVE COMMITTEE; MULTIPLE SIGNATURES. In the event that more
          than one Person has been duly nominated to serve on the
          Administrative Committee and has signified in writing the acceptance
          of such designation, the signature(s) of one or more Persons may be
          accepted by an interested party as conclusive evidence that the
          Administrative Committee has duly authorized the action therein set
          forth and as representing the will of and binding upon the whole
          Administrative Committee. No Person receiving such documents or
          written instructions and acting in good faith and in reliance thereon
          shall be obliged to ascertain the validity of such action under the
          terms of this Plan. The Administrative Committee shall act by a
          majority of its members at the time in office, and such action may be
          taken either by a vote at a meeting or in writing without a meeting.

     6B.7 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR. The Plan
          Administrator, or any member of the Administrative Committee, may
          resign at any time by delivering to the Employer a written notice of
          resignation, to take effect at a date specified therein, which shall
          not be less than 30 days after the delivery thereof, unless such
          notice shall be waived.

<PAGE>   93
          The Plan Administrator may be removed with or without cause by the
          Employer by delivery of written notice of removal, to take effect at
          a date specified therein, which shall be not less than thirty (30)
          days after delivery thereof, unless such notice shall be waived.

          The Employer, upon receipt of or giving notice of the resignation or
          removal of the Plan Administrator, shall promptly designate a
          successor Plan Administrator who must signify acceptance of this
          position in writing. In the event no successor is appointed, the
          Board of Directors of the Employer will function as the
          Administrative Committee until a new Plan Administrator has been
          appointed and has accepted such appointment.

     6B.8 INVESTMENT MANAGER. The Plan Administrator may appoint, in writing,
          an Investment Manager or Managers to whom is delegated the authority
          to manage, acquire, invest or dispose of all or any part of the Plan
          or Trust assets. With regard to the assets entrusted to his care, the
          Investment Manager shall provide written instructions and directions
          to the Employer or Trustee, as applicable, who shall in turn be
          entitled to rely upon such written direction. This appointment and
          delegation shall be evidenced by a signed written agreement.

     6B.9 DELEGATION OF DUTIES. The Plan Administrator shall have the power, to
          the extent permitted by law, to delegate the performance of such
          Fiduciary and non-Fiduciary duties, responsibilities and functions as
          the Plan Administrator shall deem advisable for the proper management
          and administration of the Plan in the best interests of the
          Participants and their Beneficiaries.


                              6C. TRUST AGREEMENT

     This agreement entered into by and among the Employer, the Plan
     Administrator and the Trustee pursuant to the Adoption Agreement completed
     and signed by the Employer, the Plan Administrator and Trustee, hereby 
     establishes the Trust with the following provisions to form a part of and
     implement the provisions of the Plan:

     6C.1 CREATION AND ACCEPTANCE OF TRUST. The Trustee, by joining in the
          execution of the Adoption Agreement, accepts the Trust hereby created

          When two or more persons serve as Trustee, they are specifically
          authorized, by a written agreement between themselves, to allocate
          specific responsibilities, obligations or duties among themselves. An
          original copy of such written agreement is to be delivered to the
          Plan Administrator.

     6C.3 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR TRUSTEE. Any
          Trustee may resign at any time by delivering to the Plan
          Administrator a written notice of resignation, to take effect at a

          the delivery thereof, unless such notice shall be waived.

          The Trustee may be removed with or without cause by the Board of
          Directors by delivery of a written notice of removal, to take effect

<PAGE>   94
          In the case of the resignation or removal of a Trustee, the Trustee
          shall have the right to a settlement of its account, which may be
          made, at the option of the Trustee, either (1) by judicial settlement
          in an action instituted by the Trustee in a court of competent
          jurisdiction, or (2) by written agreement of settlement between the
          Trustee and the Plan Administrator.

          Upon such settlement, all right, title and interest of such Trustee
          in the assets of the Trust and all rights and privileges under this
          Agreement theretofore vested in such Trustee shall vest in the
          successor Trustee, and thereupon all future liability of such Trustee
          shall terminate; provided, however, that the Trustee shall execute,
          acknowledge and deliver all documents and written instruments which
          are necessary to transfer and convey the right, title and interest in
          the Trust assets, and all rights and privileges to the successor
          Trustee.

          The Board of Directors, upon receipt of notice of the resignation or
          removal of the Trustee, shall promptly designate a successor Trustee,
          whose appointment is subject to acceptance of this Trust in writing

          Trustee.

     6C.4 TAXES, EXPENSES AND COMPENSATION OF TRUSTEE. The Trustee shall deduct

          be imposed upon the Trust fund or the income thereof or which the

          therein.

          The Employer shall pay the Trustee annually its expenses in
          administering the Trust and a reasonable compensation for its service
          as Trustee hereunder if the Trustee is not an Employee of the Plan,
          at a rate to be agreed upon from time to time. The reasonable
          compensation shall include that for any extraordinary services.

     6C.5 TRUSTEE ENTITLED TO CONSULTATION. The Trustee shall be entitled to
          advice of counsel, which may be counsel for the Plan or the Employer,
          in any case in which the Trustee shall deem such advice necessary.
          With the exception of those powers and duties specifically allocated
          to the Trustee by the express terms of this Plan, it shall not be the
          responsibility of the Trustee to interpret the terms of the Plan or
          Trust and the Trustee may request, and is entitled to receive
          guidance and written direction from the Plan Administrator on any

     6C.6 RIGHTS, POWERS AND DUTIES OF TRUSTEE. The Trustee shall have the
          following rights, powers, and duties:

          (a)  The Trustee shall be responsible for the safekeeping and
               administering of the assets of this Plan and Trust in accordance
               with the provisions of this Agreement and any amendments thereto.
               The duties of the Trustee under this Agreement shall be
               determined solely by the express provisions of this Agreement and
               no other further duties or responsibilities shall be implied.
               Subject to the terms of this Plan and Trust, the Trustee shall be
               fully protected and shall incur no liability in acting in
               reliance upon the written instructions or directions of the Plan
               Administrator or a duly designated Investment Manager or any
               other Named Fiduciary.

          (b)  The Trustee shall have all powers necessary or convenient for
               the orderly and efficient performance of its duties hereunder,
               including but not limited to those specified in this Section. The
               Trustee may appoint one or more administrative agents or contract
               for the performance of such


Article VI - Overseer Provisions               -86-
<PAGE>   95
               administrative and service functions as it may deem necessary
               for the effective installation and operation of the Plan and 
               Trust.

          (c)  The Trustee shall have the power to collect and receive any and
               all monies and other property due hereunder and to give full
               discharge and acquittance therefor; to settle, compromise or
               submit to arbitration any claims, debts, or damages due or owing
               to or from the Trust; to commence or defend suits or legal
               proceedings wherever, in its judgement, any interest of the
               Trust requires it; and to represent the Trust in all suits or
               legal proceedings in any court of law or equity or before any
               other body or tribunal. It shall have the power generally to do
               all acts, whether or not expressly authorized, which the Trustee
               in the exercise of its Fiduciary responsibility may deem
               necessary or desirable for the protection of the Trust and the
               assets thereof.

          (d)  The Trustee shall make application to the Insurance Company for
               the Annuity Contract required hereunder and shall take all
               necessary steps to obtain any Life Insurance Policies elected on
               the lives of Participants hereunder. In applying for the Annuity
               Contract, the Trustee may indicate that, unless it directs the
               Insurance Company otherwise, it shall be entitled to receive all
               cash payments for further distribution to Participants and
               Beneficiaries.

          (e)  The Trustee may temporarily hold cash balances and shall be
               entitled to deposit any such funds received in a bank account or
               bank accounts in the name of the Trust in any bank or banks
               selected by the Trustee, including the banking department of the
               Trustee, pending disposition of such funds in accordance with the
               Trust. Any such deposit may be made with or without interest.

          (f)  The Trustee shall obtain and deal with any Life Insurance
               Policies or other assets of this Trust held or received under
               this Plan only in accordance with the written directions from the
               Plan Administrator. The Trustee shall be under no duty to
               determine any facts or the propriety of any action taken or
               omitted by it in good faith pursuant to instructions from the
               Plan Administrator.

          (g)  All contributions made to the Trust fund under this Plan shall be
               paid by the Trustee to the Insurance Company under the Annuity
               Contract within 30 days after the date such contributions were
               due under the Plan.  However, in lieu of holding any 
               contributions made to the Trust fund, the Trustee may direct that
               all such contributions be made to the Trust fund, the Trustee may
               direct that all such contributions be made directly to the
               Insurance Company under the Annuity Contract or any Life
               Insurance Policy. The Employer shall keep the Trustee informed of
               all contributions made directly to the Insurance Company in
               accordance with the Trustee's instructions.

          (h)  If the whole or any part of the Trust shall become liable for the
               payment of any estate, inheritance, income or other tax which the
               Trustee shall be required to pay, the Trustee shall have full
               power and authority to pay such tax out of any monies or other
               property in its hands for the account of the person whose
               interest hereunder is so liable.  Prior to making any payment,
               the Trustee may require such releases or other documents from any
               lawful taxing authority as it shall deem necessary. The Trustee
               shall not be liable



Article VI - Overseer Provisions      -87-

                                
<PAGE>   96
          for any nonpayment of tax when it distributes an interest hereunder
          on instructions from the Plan Administrator.

     (i)  The Trustee shall keep a full, accurate and detailed record of all
          transactions of the Trust which the Plan Administrator shall have the
          right to examine at any time during the Trustee's regular business
          hours. Following the close of the fiscal year of the Trust, or as soon
          as practical thereafter, the Trustee shall furnish the Plan
          Administrator with a statement of account. This account shall set
          forth all receipts, disbursements and other transactions effected by
          the Trustee during said year.

          The Plan Administrator shall promptly notify the Trustee in writing
          of its approval or disapproval of the account. The Plan
          Administrator's failure to disapprove the account within 60 days after
          receipt shall be considered an approval. The approval by the Plan
          Administrator shall be binding as to all matters embraced in any
          statement to the same extent as if the account of the Trustee had been
          settled by judgment or decree of a court of competent jurisdiction
          under which the Trustee, Plan Administrator, Employer and all persons
          having or claiming any interest in the Trust were parties; provided,
          however, that the Trustee may have its account judicially settled if
          it so desires.

     (j)  If, at any time, there shall be a dispute as to the person to whom
          payment or delivery of monies or property should be made by the
          Trustee, or regarding any action to be taken by the Trustee, the
          Trustee may postpone such payment, delivery or action, retaining the
          funds or property involved, until such dispute shall have been
          resolved in a court of competent jurisdiction or the Trustee shall
          have been indemnified to its satisfaction or until it has received
          written direction from the Plan Administrator.

     (k)  Anything in this instrument to the contrary notwithstanding, it shall
          be understood that the Trustee shall have no duty or responsibility
          with respect to the determination of matters pertaining to the
          eligibility of any Employee to become or remain a Participant
          hereunder, the amount of benefit to which any Participant or
          Beneficiary shall be entitled hereunder, all such responsibilities
          being vested in the Plan Administrator. The Trustee shall have no duty
          to collect any contribution from the Employer and shall not be
          concerned with the amount of any contribution nor the application of
          any contribution formula.

6C.7 EVIDENCE OF TRUSTEE ACTION. In the event that the Trustee comprises two or
     more Trustees, then those Trustees may designate one such Trustee to
     transmit all decisions of the Trustee and to sign all necessary notices and
     other reports on behalf of the Trustee. All notices and other reports
     bearing the signature of the individual Trustee so designated shall be
     deemed to bear the signatures of all the individual Trustees and all
     parties dealing with the Trustee are entitled to rely on any such notices
     and other reports as authentic and as representing the action of the
     Trustee.

6C.8 INVESTMENT POLICY. This Plan has been established for the sole purpose of
     providing benefits to the Participants and their Beneficiaries. In
     determining its investments hereunder, the Trustee shall take account of
     the advice provided by the Plan Administrator as to funding policy and the
     short and long-range needs


Article VI - Overseer Provisions     -88-
<PAGE>   97
          of the Plan based on the evident and probable requirements of the Plan
          as to the time benefits shall be payable and the requirements
          therefor.

     6C.9 PERIOD OF THE TRUST. If it shall be determined that the applicable
          State law requires a limitation on the period during which the
          Employer's Trust shall continue, then such Trust shall not continue
          for a period longer than 21 years following the death of the last of
          those Participants including future Participants who are living at the
          Effective Date hereof. At least 180 days prior to the end of the
          twenty-first year as described in the first sentence of this Section
          the Employer, the Plan Administrator and the Trustee shall provide for
          the establishment of a successor trust and transfer of Plan assets to
          the Trustee.  If applicable State law requires no such limitation,
          then this Section shall not be operative.

                           6D. THE INSURANCE COMPANY

     6D.1 DUTIES AND RESPONSIBILITIES. The Insurance Company shall issue the
          Annuity Contract and any Policies hereunder and thereby assumes all
          the duties and responsibilities set forth therein. The terms of the
          Annuity Contract may be changed as provided therein without amending
          this Plan, provided such changes shall conform (1) to the requirements
          for qualification under Code section 401(a), as amended from time to
          time and (2) to ERISA, as amended from time to time.

     6D.2 RELATION TO EMPLOYER, PLAN ADMINISTRATOR AND PARTICIPANTS. The
          Insurance Company may receive the statement of the Plan Administrator
          or, if the Plan Administrator so designates, the Employer or the
          Trustee, as conclusive evidence of any of the matters decided in the
          Plan, and the Insurance Company shall be fully protected in taking or
          permitting any action on the basis thereof and shall incur no
          liability or responsibility for so doing. The Insurance Company shall
          not be required to look into the terms of the Plan, to question any
          action by the Employer or the Plan Administrator or any Participant
          nor to determine that such action is properly taken under the Plan.
          The Insurance Company shall be fully discharged from any and all
          liability with respect to any payment to any Participant hereunder in
          accordance with the terms of the Annuity Contract or of any Policies
          under the Plan.  The Insurance Company shall not be required to take
          any action contrary to its normal rules and practices.

     6D.3 RELATION TO TRUSTEE. The Insurance Company shall not be required to
          look into the terms of the Plan or question any action of the Trustee,
          and the Insurance Company shall not be responsible for seeing that any
          action of the Trustee is authorized by the terms hereof. The Insurance
          Company shall be under no obligation to take notice of any change in
          Trustee until evidence of such change satisfactory to the Insurance
          Company shall have been given to the Insurance Company in writing at
          its home office.

                             6E. ADOPTING EMPLOYER

     6E.1 ELECTION TO BECOME ADOPTING EMPLOYER. With the consent of the Employer
          and Trustee, if any, any employer, which along with the Employer is

           provisions.

     6E.2  DEFINITION.  Any employer eligible to adopt this Plan under the
           provisions of Section 6E.1 and which adopts this Plan and all of its
           provisions, shall be known as an Adopting Employer and shall be
           included within the term Employer, as defined in Section 1.24.

     6E.3  EFFECTIVE DATE OF PLAN. The effective date of the Plan for an
           Adopting Employer on other than the date specified in the Adoption
           Agreement shall be the first day of the Plan Year in which such
           Adopting Employer adopts this Plan.

     6E.4  FORFEITURES. Forfeitures of any nonvested portion of a Participant's
           Account, as selected by the Employer in the Adoption Agreement, shall
           be allocated only to other Participants who are employed by the
           Adopting Employer who made the contributions to such Participant's
           Account, or shall be used as a credit only for such Adopting
           Employer.

     6E.5  CONTRIBUTIONS. All contributions made by an Adopting Employer shall
           be determined separately by each Adopting Employer and shall be paid
           to and held by the Plan for the exclusive benefit of the Employees of
           such Adopting Employer and the Beneficiaries of such Employees,
           subject to all the terms and conditions of this Plan. The Plan
           Administrator shall separate books and records concerning the affairs

           unless paid for by such Adopting Employer. The expenses necessary to
           administer the Plan for each Adopting Employer shall be determined by
           the ratio of the value of all Participants' Accounts of such
           Adopting Employers to the total value of all Participants' Accounts
           of each Adopting Employer.

     6E.7  SUBSTITUTION OF PLANS. Subject to the provisions of Section 7C, any
           Adopting Employer shall be permitted to withdraw from its
           participation in this Plan.  The consent of the Employer or any other
           Adopting Employer shall not be required.

     6E.8  TERMINATION OF PLANS. If any Adopting Employer elects to terminate
           its Plan pursuant to Sections 7B.4, 7B.5 and 7B.6, such termination
           shall in no way affect the Plan of any other Adopting Employer.

     6E.9  AMENDMENT. Amendment of this Plan by the Employer or any Adopting
           Employer shall only be by the written consent of the Employer and
           each and every Adopting Employer and with the consent of the Trustee,

<PAGE>   100
          (g)  REQUIRED AGGREGATION GROUP. The term-Required Aggregation Group
               means (1) each qualified plan of the Employer in which at least
               one Key Employee participates or participated at any time during
               the Determination Period (regardless of whether the plan has
               terminated), and (2) any other qualified plan of the Employer
               which enables a plan described in (1) to meet the requirements of
               Code sections 401(a)(4) or 410.

          (h)  TOP-HEAVY PLAN. For any Plan Year beginning after December 31,
               1983, this Plan is Top-Heavy if any of the following conditions
               exists:

               (1)  If the Top-Heavy Ratio for this Plan exceeds 60 percent and
                    this Plan is not part of any Required Aggregation Group or
                    Permissive Aggregation Group of plans.

               (2)  If this 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
                    percent.

               (3)  If this 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 percent.

          (i)  TOP-HEAVY RATIO. The term Top-Heavy Ratio means:

               (1)  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, 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 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 related regulations.
                    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
                    related regulations.

               (2)  If the Employer maintains one or more defined contribution
                    plans (including any simplified employee pension plans as
                    defined in Code section 408(k)) 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, 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 (1) above, and the Present
                    Value of accrued benefits under the aggregated defined
                    benefit plan or plans


Article VII - Special Circumstances   -92-
<PAGE>   101
               for all Key Employees as of the Determination Date(s), and 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 (1) 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 related
               regulations. 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.

          (3)  For purposes of (1) and (2) 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 (I) who is
               not a Key Employee but who was a Key Employee in a prior year, or
               (ii) 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 shall 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. QVEC 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 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 (a) the method, if any, that uniformly applies
               for a accrual purposes under all defined benefit plans maintained
               by the Employer, or (b) 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).

     (j)  VALUATION DATE. The term Valuation Date means the date specified in
          the Top-Heavy Provisions section of the Adoption Agreement as of which
          account balances or accrued benefit are valued for purposes of
          calculating the Top-Heavy Ratio.

7A.2 MINIMUM ALLOCATION. For any Plan Year in which the Plan is Top-Heavy, the
     following will apply:

     (a)  Except as otherwise provided in (c) and (d) below, the Employer
          contributions and Forfeitures allocated on behalf of any Participant
          who is not a Key Employee shall not be less than the lesser of three
          percent of such Participant's Compensation or in the case where the
          Employer has no defined benefit plan which designates this Plan to
          satisfy Code section 401, the largest percentage of Employer
          contributions and Forfeitures, as limited by Code section 401(a)(17),
          allocated on behalf of any Key Employee for that year. The Minimum
          Allocation is determined without


Article VII - Special Circumstances   -93-
<PAGE>   102
               regard to any Social Security contribution.  This Minimum
               Allocation shall be made 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 of (1) the Participant's failure to complete
               1,000 Hours of Service (or any equivalent provided in the Plan),
               or (2) the Participant's failure to make Required Employee
               Contributions to the Plan, or (3) Compensation less than a stated
               amount.

          (b)  For purposes of computing the Minimum Allocation, Compensation
               shall mean Compensation as defined in the Compensation section of
               the Adoption Agreement as limited by Code section 401(a)(17).

               Notwithstanding the above, if elected by the Employer in the
               Adoption Agreement, Compensation shall include any amount which
               is contributed by the Employer pursuant to a salary reduction
               agreement and which is not includable in the Employee's gross
               income under Code sections 125, 401(a)(8), 402(h) or 403(b).

          (c)  The provision in (a) above shall not apply to any Participant who
               was not employed by the Employer on the last day of the Plan
               Year.

          (d)  The provision in (a) above shall not apply to any Participant to
               the extent the Participant is covered under any other plan or
               plans of the Employer and the Employer has provided in the
               Top-Heavy Provisions section of the Adoption Agreement that the
               Minimum Allocation or benefit requirement applicable to
               Top-Heavy plans will be met in the other plan or plans.

          (e)  The Minimum Allocation required (to the extent required to be
               nonforfeitable under Code section 416(b)) may not be forfeited
               under Code sections 411(a)(3)(B) or 411(a)(3)(D).

          (f)  Neither Elective Deferral Contributions nor matching
               Contributions may be taken into account for the purpose of
               satisfying this Minimum Allocation Requirement.

     7A.3 MINIMUM VESTING SCHEDULE.  For any Plan Year in which this Plan is
          Top-Heavy, one of the minimum vesting schedules as elected by the
          Employer in the Adoption Agreement will automatically apply to the
          Plan.  The minimum vesting schedule applies to all benefits within the
          meaning of Code section 411(a)(7) except those attributable to
          Employee Contributions, Elective Deferral Contributions, QVEC
          Contributions and Rollover Contributions including benefits accrued
          before the effective date of Code section 416 and benefits accrued
          before the Plan became Top-Heavy.  Further, no decrease in a
          Participant's nonforfeitable percentage may occur in the event the
          Plan's status as Top-Heavy changes for any Plan Year.  However, this
          Section does not apply to the account balances of any Employee who
          does not have an Hour of Service after the Plan has initially become
          Top-Heavy.  Such Employee's account balance attributable to Employer
          contributions and Forfeitures will be determined without regard to
          this Section.

<PAGE>   103
               7B.  AMENDMENT, TERMINATION OR MERGER OF THE PLAN

     7B.1 AMENDMENT OF ELECTIONS UNDER ADOPTION AGREEMENT BY EMPLOYER. The party
          elected by the Employer in the Adoption Agreement shall have the right
          from time to time to change the elections under its Adoption Agreement
          in a manner consistent with the Plan, provided that such amendment or
          modification shall be in accordance with the Board of Director's
          resolution, if applicable, that describes the amendment procedure and
          provided further that the written amendment or modification is signed
          by the party elected by the Employer in the Adoption Agreement. The
          amendment must be accepted by the Sponsoring Organization. Upon any
          such change in the Elections under the Adoption Agreement, the Plan
          Administrator, the Trustee and the Sponsoring Organization shall be
          furnished a copy thereof. If the Plan's vesting schedule is amended,
          or the Plan is amended in any way that directly or indirectly affects
          the computation of the Participant's nonforfeitable percentage or if
          the Plan is deemed amended by an automatic change to a top-heavy
          vesting schedule, each Participant with at least 3 years of Service
          with the Employer may elect, in writing, within a reasonable period
          after the adoption of the amendment or change, to have the
          nonforfeitable percentage computed under the Plan without regard to
          such amendment or change. For Participants who do not have at least 1
          Hour of Service in any Plan Year beginning after December 31, 1988,
          the preceding sentence shall be applied by substituting "5 years of
          Service" for "3 years of Service" where such language appears.

          The period during which the election must be made by the Participant
          shall begin no later than the date the Plan amendment is adopted and
          end no later than after the latest of the following dates:

          (a)  The date which is 60 days after the day the amendment is adopted;

          (b)  The date which is 60 days after the day the amendment becomes
               effective; or

          (c)  The date which is 60 days after the day the Participant is issued
               written notice of the amendment by the Employer or Plan
               Administrator.

          Such written election by a Participant shall be made to the Plan
          Administrator, who shall then give written notice to the Insurance
          Company.

          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 Code section
          412(c)(8). 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. Furthermore, if the vesting schedule of a
          Plan is amended, in the case of an Employee who is a Participant as of
          the later of the date such amendment is adopted or the date it becomes
          effective, the nonforfeitable percentage (determined as of such date)
          of such Employee's Employer-derived Accrued Benefit will not be less
          than the percentage computed under the Plan without regard to such
          amendment.

          In the event of an amendment to a money purchase pension plan
          (including a target benefit plan) to convert it to a profit sharing
          plan (including a thrift plan or plan with a 401(k) feature), the
          resulting plan shall separately account in each affected Participant's
          Account for amounts attributable to coverage under the



Article VII - Special Circumstances   -95-

<PAGE>   104
          money purchase plan, including future earnings on such amounts. On and
          after the date of such amendment, these money purchase plan amounts
          shall remain subject to the money purchase plan restrictions on
          distribution.

          The Employer may (1) change the choice of options in the Adoption
          Agreement, (2) add overriding language in the Adoption Agreement when
          such language is necessary to satisfy Code sections 415 or 416 because
          of the required aggregation of multiple plans, and (3) 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. An Employer that amends the Plan for
          any other reason, including a waiver of the minimum funding
          requirements under Code section 412(d), will no longer participate in
          this prototype plan and will be considered to have an individually
          designed plan.

     7B.2 AMENDMENT OF PLAN, TRUST, AND FORM OF ADOPTION AGREEMENT. The
          Sponsoring Organization may amend this Plan and Trust, and the form of
          the Adoption Agreement, and the Employer in adopting this Plan and the
          Plan Administrator and the Trustee in accepting appointment as Plan
          Administrator and as Trustee, shall be deemed to have consented to any
          such amendment by executing the Adoption Agreement, provided that the
          written consent of the Trustee and the Plan Administrator to any
          change affecting their duties or responsibilities shall first be
          obtained. Upon any such amendment by the Sponsoring Organization, the
          Plan Administrator, the Employer and the Trustee shall be furnished
          with a copy thereof.

     7B.3 CONDITIONS OF AMENDMENT. Neither the Sponsoring Organization nor the
          Employer shall make any amendment which would cause the Plan to lose
          its status as a qualified plan within the meaning of Code section
          401(a).

     7B.4 TERMINATION OF THE PLAN. The Employer intends to continue the Plan
          indefinitely for the benefit of its Employees, but reserves the right
          terminate the Plan at any time by resolution of its Board of
          Directors. Upon such termination, the liability of the Employer to
          make Employer contributions hereunder shall terminate. The Plan shall
          terminate automatically upon complete discontinuance of Employer
          contributions hereunder, if the Plan is a profit sharing plan or a
          thrift plan.

     7B.5 FULL VESTING. Upon the termination or partial termination of the Plan,
          or upon complete discontinuance of Employer contributions, the rights
          of all affected Participants in and to the amounts credited to each
          such Participant's Account and to any Policies on each Participant's
          life shall be 100% vested and nonforfeitable. Thereupon, each
          Participant shall receive a total distribution of his Participant's
          Account (including any amounts in the Forfeiture Account allocated in
          accordance with Section 7B.6) in accordance with the terms and
          conditions of Section 2A. If the Plan terminates, the assets will be
          distributed from the Trust as soon as administratively feasible.

     7B.6 APPLICATION OF FORFEITURES. Upon the termination of the Plan, any
          amount in the Forfeiture account which has not been applied as of such
          termination to reduce the Employer contribution, or has not been
          allocated as of such termination, shall be credited on a pro-rata
          basis to each Participant's Account in the same manner as the last
          Employer contribution made under the Plan.


Article VII - Special Circumstances     -96-
<PAGE>   105
   7B.7 MERGER WITH OTHER PLAN. In the case of any merger with or transfer of
        assets or liabilities to any other qualified plan after 
        September 2, 1974:

        (a)  The sum of the account balances in each plan shall equal the fair
             market value (determined as of the date of the merger or transfer
             as if the plan had then terminated) of the entire plan assets.

        (b)  The assets or liabilities of each plan shall be combined to form
             the assets of the plan as merged (or transferred), and each
             Participant in the plan merged (or transferred) shall have an
             account balance equal to the sum of the account balances the
             Participant had in the plans immediately prior to the merger (or
             transfer).

        (c)  Immediately after the merger (or transfer), each Participant in
             the plan merged (or transferred) shall have an account balance
             equal to the sum of the account balances the Participant had in
             the plans immediately prior to the merger (or transfer).

        (d)  Immediately after the merger (or transfer), each Participant in
             the plan merged (or transferred) shall be entitled to the same
             optional benefit forms as they were entitled to immediately prior
             to the merger (or transfer).

        (e) In the event of a merger (or transfer) of a money purchase pension
            plan (including a target benefit plan) and a profit sharing plan
            (including a thrift plan or plan with a 401(k) feature), the
            resulting plan shall separately account in each affected
            Participant's Account for amounts attributable to coverage under
            the money purchase plan, including future earnings on such amounts.
            On and after the date of such merger (or transfer), these money
            purchase plan amounts shall remain subject to the money purchase
            plan restrictions on distribution.

   7B.8  TRANSFER FROM OTHER PLANS. If elected in the Adoption Agreement, the
         Employer may cause all or any of the assets held in another qualified
         pension or profit sharing plan meeting the requirements of Code
         section 401(a) to be transferred to the Plan pursuant to a merger or
         consolidation of this Plan with such other plan or for any other
         allowable purpose. Upon receipt of such assets, the Plan shall
         separately account for such amounts in each affected Participant's
         Account. Such transfer shall be made without regard to the Limitations
         on Allocations imposed in Section 4B.

   7B.9  TRANSFER TO OTHER PLANS. Upon written direction from the Employer, the
         Plan shall transfer some or all of the assets held under this Plan to
         another qualified pension or profit sharing plan meeting the
         requirements of Code section 401(a) and sponsored by the Employer.

   7B.10 APPROVAL BY THE INTERNAL REVENUE SERVICE. Notwithstanding any other
         provisions of this Plan, the Employer's adoption of this Plan is
         subject to the condition precedent that the Employer's Plan shall be
         approved and qualified by the Internal Revenue Service as meeting the
         requirements of Code section 401(a) and, if applicable, that the Trust
         established hereunder shall be entitled to exemption under the
         provisions of Code section 501(a). In the event the Plan initially
         fails to qualify and the Internal Revenue Service issues a final
         ruling that the Employer's Plan or Trust fails to so qualify as of the
         Effective Date, all liability of the Employer to make further Employer
         contributions hereunder shall cease. The Insurance Company, Plan
         Administrator, Trustee and any other Named Fiduciary shall be notified
         immediately by the Employer, in writing, of such



Article VII - Special Circumstances     -97-
<PAGE>   106
            failure to qualify. Upon such notification, the value of the
            Participants' Accounts, including the then value of any Life
            Insurance Policies, shall be distributed in cash subject to the
            terms and conditions of Section 5B. That portion of such
            distribution which is attributable to Participant's Employee
            Contributions, if any, shall be paid to the Participant, and the
            balance of such distribution shall be paid to the Employer. Upon the
            death of any Participant prior to the actual surrender of a Life
            Insurance Policy or Policies on his life, the death benefit shall be
            payable to the Participant's Beneficiary.

            If the Employer's Plan fails to attain or retain qualification, such
            Plan will no longer participate in this prototype plan and will be
            considered an individually designed plan.

     7B.11  SUBSEQUENT UNFAVORABLE DETERMINATION. If the Employer is notified
            subsequent to initial favorable qualification that the Plan is no
            longer qualified within the meaning of Code section 401(a) or, if
            applicable, that the Trust is no longer entitled to exemption under
            the provisions of Code section 501(a), and if the Employer shall
            fail within a reasonable time to make any necessary changes in order
            that the Plan shall so qualify, the Participants' Accounts,
            including any Life Insurance Policies or the values thereof, shall
            be fully vested and nonforfeitable and shall be disposed of in the
            manner set forth in Sections 7B.5 and 7B.6 above.

                           7C. SUBSTITUTION OF PLANS

     7C.1   SUBSTITUTION OF PLANS. Subject to the provisions of Section 7B.7,
            the Employer may substitute an individually designed plan or a
            master or another prototype plan for this Plan without terminating
            this Plan as embodied herein, and this shall be deemed to constitute
            an amendment and restatement in its entirety of this Plan as
            heretofore adopted by the Employer; provided, however that the
            Employer shall have certified to the Insurance Company and the
            Trustee, if applicable, that this Plan is being continued on a
            restated basis which meets the requirements of Code section 401(a)
            and ERISA.

            Any such changes shall be subject to the provisions of Sections 7B.1
            and 7B.2 of the Plan.

     7C.2   TRANSFER OF ASSETS. Upon 90 days' written notification from the
            Employer and the Trustee (unless the Insurance Company shall accept
            a shorter period of notification) that a different plan meeting the
            requirements set forth in Section 7C.1 above has been executed and
            entered into by the Plan Administrator and the Employer, and after
            the Insurance Company and the Trustee have been furnished the
            Employer's certification in writing that the Employer intends to
            continue the Plan as a qualified plan under Code section 401(a) and
            ERISA, the Insurance Company shall transfer the value of all
            Participants' Accounts under the Annuity Contract to the Trustee or
            such person or persons as may be entitled to receive the same, in
            accordance with the terms of the Annuity Contract. The Trustee shall
            likewise make a similar transfer, including all Life Insurance
            Policies, or the values thereof, to such person or persons as may be
            entitled to receive same. The Insurance Company and the Trustee may
            rely fully on the representations or directions of the Employer with
            respect to any such transfer and shall be fully protected and
            discharged with respect to any such transfer made in accordance with
            such representations, instructions, or directions.



Article VII - Special Circumstances   -98-
<PAGE>   107
     7C.3 SUBSTITUTION FOR PRE-EXISTING MASTER OR PROTOTYPE PLAN. This Plan is
          designed:
          
          (a)  For adoption by an Employer not previously covered under a master
               or prototype plan sponsored by Connecticut General Life Insurance
               Company; or

          (b)  For adoption by an Employer in substitution for a pre-existing
               master or prototype plan sponsored by Connecticut General Life
               Insurance Company.

          If this Plan is adopted in substitution for such a pre-existing master
          or prototype plan, it shall be deemed to amend the Employer's prior
          Plan in its entirety effective as of the date specified in the
          Employer's Adoption Agreement. The Employer's Plan as so amended shall
          continue in full force and effect and no termination thereof shall be
          deemed to have occurred.

     7C.4 PARTIAL SUBSTITUTION OR PARTIAL TRANSFER OF THE PLAN OR ASSETS. In the
          event this Plan is adopted as the result of a partial substitution or
          partial transfer of the Plan or the assets under the prior Plan as a
          result of a merger, spinoff, consolidation or any other allowable
          purpose, the Plan and all transactions allowable under it are subject
          to the rules established by the Employer to address the orderly
          transition of the Plan or assets.

                          ARTICLE VIII - MISCELLANEOUS


     8.1  NONREVERSION. This Plan has been adopted by the Employer for the
          exclusive benefit of the Participants and their Beneficiaries. Except
          as otherwise provided in Section 7B.10 and Section 8.6, under no
          circumstances shall any funds contributed hereunder at any time revert
          to or be used by the Employer, nor shall any such funds or assets of
          any kind be used other than for the benefit of the Participants or
          their Beneficiaries.

     8.2  GENDER AND NUMBER. When necessary to the meaning hereof, and except
          when otherwise indicated by the context, either the masculine or the
          neuter pronoun shall be deemed to include the masculine, the
          feminine, and the neuter, and the singular shall be deemed to include
          the plural.

     8.3  REFERENCE TO THE INTERNAL REVENUE CODE AND ERISA. Any reference
          herein to any section of the Internal Revenue Code, ERISA, or to any
          other statute or law shall be deemed to include any successor law of
          similar import.

     8.4  GOVERNING LAW. The Plan and Trust, if applicable, shall be governed
          and construed in accordance with the laws of the state where the
          Employer or Trustee has its principal office in the United States.

     8.5  COMPLIANCE WITH THE INTERNAL REVENUE CODE AND ERISA. This Plan is
          intended to comply with all requirements for qualification under the
          Internal Revenue Code and ERISA, and if any provision hereof is
          subject to more than one interpretation or any term used herein is
          subject to more than one construction, such ambiguity shall be
          resolved in favor of that interpretation or construction which is
          consistent with the Plan being so qualified. If any provision of the
          Plan is held invalid or unenforceable, such invalidity or
          unenforceability shall not affect any other provisions, and this Plan
          shall be construed and enforced as if such provision had not been
          included.

     8.6  CONTRIBUTION RECAPTURE. Notwithstanding any other provisions of this
          Plan, (1) in the case of a contribution which is made by an Employer
          by a mistake of fact, Section 8.1 shall not prohibit the return of
          such contribution to the Employer within one year after the payment of
          the contribution, and (2) if a contribution is conditioned upon the
          deductibility of the contribution under Code section 404, then, to the
          extent the deduction is disallowed, Section 8.1 shall not prohibit the
          return to the Employer of such contribution (to the extent disallowed)
          within one year after the disallowance of the deduction. The amount
          which may be returned to the Employer is the excess of (1) the amount
          contributed over (2) the amount that would have been contributed had
          there not occurred a mistake of fact or a mistake in determining the
          deduction. Earnings attributable to the excess contribution may not be
          returned to the Employer, but losses attributable thereto must reduce
          the amount to be so returned. Furthermore, if the withdrawal of the
          amount attributable to the mistaken contribution would cause the
          balance of any Participant's Account to be reduced to less than the
          balance which would have been in the Participant's Account had the
          mistaken amount not been contributed, then the amount to be returned
          to the Employer would have to be limited so as to avoid such
          reduction.


Article VIII - Miscellaneous         -100-
<PAGE>   109
     In the event that the Commissioner of the 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.

     Notwithstanding the above, an excess or returned contribution shall not be
     returned to the Employer if the Employer has taken Davis-Bacon Act credit
     for such contribution. These excess or mistaken contributions shall be
     paid to the Employee for whom such credit is taken.

Gentlemen:

           We have acted as counsel to Pioneer Companies, Inc. (the "Company")
in connection with the Company's Registration Statement on Form S-8 (the
"Registration Statement") relating to the registration under the Securities Act
of 1933, as amended, of the issuance of 250,000 shares (the "Shares") of the
Company's Class A common stock, par value $0.01 per share, pursuant to the
Pioneer Companies Savings Plan for Salaried Employees, the Pioneer Companies
Savings Plan for Henderson Bargaining Unit Employees, the Pioneer Companies
Savings Plan for Tacoma Bargaining Unit Employees, the Kemwater North America
Savings Plan, and the All Pure Savings Plan (the "Plans").

           In connection therewith, we have examined copies of such statutes,
regulations, corporate records and documents, certificates of public and
corporate officials and other agreements, contracts, documents and instruments
as we have deemed necessary as a basis for the opinion hereinafter expressed. In
such examination, we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals and the conformity
with the original documents of all documents submitted to us as copies. We have
also relied, to the extent we deem such reliance proper, upon information
supplied by officers and employees of the Company with respect to various
factual matters material to our opinion.

           Based upon the foregoing and having due regard for such legal
considerations as we deem relevant, we are of the opinion that the Shares have
been duly authorized, and that such Shares will, when issued in accordance with
the terms of the Plans, be legally issued, fully paid and nonassessable.

           We hereby consent to the use of this opinion as an exhibit to
the Registration Statement.


                                                     Very truly yours,
