3.   ELIGIBILITY AND PARTICIPATION
     -----------------------------

     3.1 Selection of Participants. The Committee will select the Key Employees
eligible to become Participants. Unless waived by the Committee, a Key Employee
must have at least one Year of Service prior to becoming a Participant. A Key
Employee so selected will become a Participant on the first July 1 or January 1
following his delivery to the Company of a Participant's Election.

     3.2 Continued Participation. The Committee may revoke an individual's right
to participate if he no longer meets the Program's eligibility requirements or
for any other reason. If a Participant's employment is terminated for any
reason, his right to participate in the Program will cease. Except as provided
in Section 5.4, such termination will not affect Stock Units already credited to
his Account.

4.   CONTRIBUTIONS AND ACQUISITION OF STOCK UNITS
     --------------------------------------------

     4.1 Acquisition of Stock Units. An account will be established to track
Stock Units for each Participant. All Contributions to a Participant's Account
will be used to acquire Stock Units at a price equal to 85% of the Fair Market
Value of a share of Common Stock on the date such Contributions are made.

     4.2 Participant's Contribution. Each Participant may elect to contribute to
the Program a percentage of his Compensation in excess of $23,700 for the
calendar year (which amount may be increased by the Committee for years after
2002). The Committee will determine the maximum percentage. Participant's
Contributions will be made on a bi-weekly basis, unless the Committee determines
otherwise.

     4.3 Forms and Modification. A Participant's Election will be made in a form
approved by the Committee. The election must be made on or before June 30 or
December 31, and will only apply to Compensation earned and payable after such
dates. An Election may be changed twice each calendar year. Once a change is
made, it will become effective on the first July 1 or January 1 following
delivery of such change to the Company.

     4.4 Matching Contributions. The Company will make a Matching Contribution
equal to 50% of the Participant's Contribution. Matching Contributions will be
made at the same time as the Participant's Contributions.

     4.5 Additional Matching Contribution. If the Company's return on adjusted
average equity for a calendar year is at least 12.5%, the Company will make an
Additional Matching Contribution equal to 50% of the Participant's Contribution
for the applicable year. If the Company fails to achieve a 12.5% return, the
Committee will determine the amount, if any, of the Additional Matching
Contribution. Such Contribution will be credited to the Account of each
Participant who was employed as of the last business day of the calendar year,
plus each Participant whose employment terminated prior to such date: (a) due to
permanent and total disability or death, or (b) after the Participant has
attained 55 years of age and has at least 5 Years of Service. Additional
Matching Contributions, if any, will be made after the end of the year when the
amount has been determined.

                                       3

<PAGE>

     4.6 Dividend Contributions. On the date a cash dividend is paid on Common
Stock, the Company will make a Dividend Contribution equal to the product of the
number of Stock Units credited to the Participant's Account on the dividend
record date times the per share cash dividend paid on Common Stock.

     4.7 Change in Capitalization. In the event of a stock dividend, stock
split, merger, consolidation or other recapitalization of the Company affecting
the number of outstanding shares of Common Stock, the number of Stock Units
credited to a Participant's Account will be appropriately adjusted.

     4.8 FICA Tax Gross-Up. The Company will pay on behalf of a Participant any
FICA taxes due on Matching Contributions and Additional Matching Contributions.
Such payment will be determined by the Committee and may include a tax
"gross-up" on such payments.

     4.9 Impact of Deferred Compensation Program. Some Participants are eligible
to defer up to 100% of their Compensation under the Company's Deferred
Compensation Program. If the Compensation remaining after such a deferral is not
sufficient to allow the Participant to make the full Participant's Contribution,
the Company will make the Matching Contribution and any Additional Matching
Contribution as though the full Participant's Contribution had been made.

5.   DISTRIBUTION
     ------------

     5.1 Distribution. Distribution of a Participant's Account will be made
within 90 days after termination of employment either in a lump sum or
installments if elected. Prior to distribution, the Stock Units will be
converted to the appropriate number of whole shares of Common Stock.

     Distribution of a Participant's Account will be based on the number of
Stock Units credited to his Account upon termination of employment. If Stock
Units are credited to the Participant's Account after a distribution has been
made (e.g., as a result of Dividend Contributions or Additional Matching
Contributions), a subsequent distribution of those Stock Units will be made.

     5.2 Form of Distribution. Distributions will be made in the form elected by
the Participant. The forms of distribution are: (a) a lump sum amount, or (b)
annual installments for up to 15 years. Annual installment distributions will be
made by January 31st of each year following the year of the initial
distribution. Each annual distribution will be equal to the balance of Stock
Units in the Account divided by the number of payments remaining.

     If the Participant (or his Beneficiary in the event of death) does not make
an election within 30 days after termination of employment, the distribution
will be made in a lump sum. If a Participant's Account value does not exceed
$50,000 on termination of employment, the distribution will be made in a lump
sum regardless of the Participant's election otherwise.

     5.3 Withholding from Distributions. When Stock Units are converted to
Common Stock for distribution, the Company may withhold from such Common Stock
any amount required to pay applicable taxes (at the Company's required
withholding rate). Alternatively, the Participant may pay such taxes in cash if
he elects to do so before the distribution date.

                                       4

<PAGE>

     5.4 Forfeiture of Stock Units. Notwithstanding the above, upon the
termination of employment of a Participant who has less than 5 Years of Service,
any Stock Units acquired by Company Matching and Additional Matching
Contributions will be forfeited (unless the Committee determines otherwise).
However, such Stock Units will not be forfeited if (a) the Participant is at
least 60 years of age upon termination of employment, or (b) the Participant's
employment is terminated due to death or total and permanent disability.

     5.5 Beneficiary. If a Participant dies before he has received all
distributions due under the Program, the remaining distributions will be made to
his Beneficiary. Each Participant may designate a Beneficiary and change his
Beneficiary from time to time. No such designation will become effective until
received in writing by the Company. If a Participant has no living designated
Beneficiary, then his Beneficiary will be his personal representative.

     5.6 Hardship Distribution. In the event of a hardship of a Participant, the
Committee may, in its sole discretion, permit distribution of such portion of
Participant's Stock Units, as it deems appropriate.

6.   ADMINISTRATION
     --------------

     6.1 Administration. Except to the extent the Committee otherwise designates
pursuant to Section 6.2(e), the Committee will control and manage the operation
and administration of the Program.

     6.2 Committee's Authority. The Committee will have such authority as may be
necessary to discharge its responsibilities under the Program, including the
authority to: (a) interpret the provisions of the Program; (b) adopt rules of
procedure consistent with the Program; (c) determine questions relating to
benefits and rights under the Program; (d) maintain records concerning the
Program; (e) designate any Company employee or committee, including the
Management Committee, to carry out any of the Committee's duties, including
authority to manage the operation and administration of the Program; and (f)
determine the content and form of the Participant's Election and all other
documents required to carry out the Program.

     6.3 Section 16 Officers. Notwithstanding the foregoing, the Committee may
not delegate its authority with respect to Section 16 Officers.

7.   CLAIMS
     ------

     7.1 Adjudication of Claims. The Committee and the Company's Secretary will
make all determinations regarding benefits under the Program in accordance with
ERISA.

     If a Participant believes he is entitled to receive a distribution under
the Program and he does not receive such distribution, he must make a claim in
writing to the Committee. The Committee will review the claim. If the claim is
denied, the Committee will provide a written notice of denial within 90 days
setting out: the reasons for the denial; provisions of the Program upon which
the denial is based; any additional information to perfect the claim and why
such information is necessary; the steps to be taken if a review is sought,
including the right to file an action under Section 502(a) of ERISA following an
adverse determination; and the time limits for requesting a review and for
review.

                                       5

<PAGE>

     If a claim is denied and the Participant desires a review, he will notify
the Secretary in writing within 60 days of the receipt of notice of denial. In
requesting a review, the Participant may review the Program or any related
document and submit any written statement he deems appropriate. The Secretary
will then review the claim and, if the decision is adverse to the Participant,
provide a written decision within 60 days setting out: the reasons for the
denial; provisions of the Program upon which the denial is based; a statement
that the Participant is entitled to receive, upon request and free of charge,
copies of documents relied upon in making the decision; and the Participant's
right to bring an action under Section 502(a) of ERISA.

8.   GENERAL PROVISIONS
     ------------------

     8.1 No Contract. Nothing contained in the Program will restrict the right
of the Employer to discharge a Participant or the right of a Participant to
resign from employment. The Program should not be construed as an employment
contract.

     8.2 No Assignment. No Participant or Beneficiary may transfer, assign or
otherwise encumber any benefits payable by the Company under the Program. Such
benefits may not be seized by any creditor of Participant or Beneficiary or
transferred by operation of law in the event of bankruptcy, insolvency or death.
Any attempted assignment or transfer will be void.

     8.3 Unfunded Program. No person will have any interest in the Company's
assets by virtue of the Program. No Participant or Beneficiary will have any of
the rights of a shareholder with respect to Stock Units.

     8.4 No Trust Created. The Program and any action taken pursuant to the
Program should not be construed as creating a trust or other fiduciary
relationship between the Company, the Participant, his Beneficiary or any other
person.

     8.5 Binding Effect. The Program will be binding upon and inure to the
benefit of the Company, its successors and assigns, and each Participant, his
heirs, personal representatives, and Beneficiaries.

     8.6 Amendments and Termination. The Company will have the right to amend or
terminate the Program at any time. However, no such amendment or termination
will deprive any Participant of the right to distribution of Stock Units
previously credited to his Account.

     8.7 Governing Law. To the extent not preempted by ERISA, this Program will
be governed by Missouri law.

     8.8 Notices. Any notice or claim given under the Program will be in writing
and signed by the party giving the same. If such notice or claim is mailed, it
will be sent by United States first class mail, postage prepaid, addressed to
the recipient's last known address as shown on the Company's records. The date
of such mailing will be deemed the date of notice.
