COMMERCE BANCSHARES, INC. EXECUTIVE INCENTIVE COMPENSATION PLAN AMENDMENT AND RESTATEMENT OF OCTOBER 4, 1996 1. PURPOSE The policy of Commerce Bancshares, Inc. ("Commerce") is to compensate its officers based on performance. The purpose of this Executive Incentive Compensation Plan ("Plan") is to provide incentive compensation awards to those individuals whose management efforts reflect a desire to meet commonly agreed upon objectives or to those who by their superior performance directly contribute to the profitability of Commerce and to encourage the retention of outstanding contributors. 2. ADMINISTRATION The Plan shall be administered by the Compensation and Benefits Committee of the Board of Directors ("Board") of Commerce, which shall consist solely of two or more directors who are "non-employee directors" under Rule 16b-3(b)(3) promulgated under the Securities Exchange Act of 1934, as amended, or any successor provision thereto. The Committee shall have authority in its sole discretion to interpret the Plan and make all determinations, including the determination of incentive compensation awards eligible to be deferred under the Plan. All determinations made by the Committee shall be final and binding. 3. ELIGIBLE PARTICIPANTS All chief executive officers, Chairmen of the Board, Presidents, and Vice Presidents of Commerce or any of its affiliated banks or subsidiary companies shall be eligible to participate in the Plan, together with such other officers of Commerce and its affiliated banks and subsidiary companies as the Committee shall determine. Directors who are not officers or employees of Commerce, an affiliated bank, or a subsidiary company, are not eligible to participate in the Plan. 4. DETERMINATION OF AWARD The Board of Commerce shall at its sole discretion approve the amount of the aggregate incentive compensation awards to be granted based on the recommendations of the Committee. Incentive compensation awards made under this Plan shall be determined with reference to performance during the preceding year. The incentive compensation awards to be made to the Chairman of the Board, President and/or Chief Executive Officer of Commerce shall be determined by the Committee and all other awards to be made under this Plan may be determined by the Committee or, should the Committee so direct, by a committee consisting of the Chief Executive Officer, a Vice Chairman designated by the Chief Executive Officer, and the chief human resources officer. 5. PAYMENT OF INCENTIVE AWARD Incentive compensation awards are generally determined and made on or before the date of the annual meeting of shareholders of Commerce. The normal method of payment will be in the form of cash and awards will be paid as soon as practicable after the awards are determined; provided, that the recipient of an award shall not have elected to defer receipt of the incentive compensation award as hereinafter provided. 6. DEFERRAL OPTIONS a. An eligible employee may elect to defer all or a portion of an incentive compensation award until the earlier to occur of retirement, death, or termination. A deferral must be expressed either as "all" or as a specified dollar amount. Any incentive compensation award above the specified amount will be paid in cash, and if the award is less than the amount deferred, the total award will be deferred. The granting of an incentive compensation award is discretionary and neither delivery of deferral election materials nor an election to defer shall affect entitlement to such an award. All deferral elections made under the Plan are irrevocable. b. In order to ensure that elections to defer incentive compensation awards are effective under applicable tax laws, all persons eligible to participate in this Plan will be given the opportunity to defer payment of all or a portion of an incentive compensation award. An election to defer must be made prior to December 31 of the year preceding the year for which performance is measured to determine the granting of an incentive compensation award. c. An eligible employee in electing a deferred payment shall also elect the account which Commerce shall make available to the participating employee and to which the relevant portion of the award deferral will be credited. The available accounts for deferral of an incentive compensation award shall consist of (a) the Treasury Bill Account, (b) the Treasury Note Account, and (c) the Commerce Stock Account. Amounts may not be transferred between accounts. d. The Treasury Bill Account and the Treasury Note Account are both bookkeeping accounts. The Treasury Bill Account will have interest credited on the deferred amount at a rate equal to the six-month treasury bill yield with the interest credited on the first day of each calendar quarter. The Treasury Note Account will have interest credited on the deferred amount at a rate equal to the four-year treasury note rate (with the rate adjusted at the end of each four-year period) with interest credited on the first day of each calendar quarter. Amounts credited to either of these accounts will be compounded on the first day of each calendar quarter. The Commerce Stock Account is a bookkeeping account the value of which will be based upon the performance of the $5.00 par value common stock of Commerce ("Commerce Stock"). Amounts deferred into the Commerce Stock Account will be credited to such account with units, each reflecting one share of Commerce Stock. Fractional units will also be credited to such account if applicable. The number of such credited units will be determined by dividing the value of the incentive compensation award which is deferred into the Commerce Stock Account by the last sale price of the Commerce Stock as reported by the National Association of Securities Dealers National Market System on the last trading day in January on which a trade of Commerce Stock is so reported. Dividends paid on the Commerce Stock shall be reflected in a participant's Commerce Stock Account. The crediting of additional units in such account shall be equal to the value of the dividends divided by the last sale price of the Commerce Stock on the date such dividend is paid. e. Commerce shall provide periodically to each participant (but not less frequently than once per calendar year) a statement setting forth the balance to the credit of such participant in each of the accounts. f. Amounts deferred under the provisions of this Plan will be disbursed to participants in accordance with the following: (1) Deferrals held in the Treasury Bill Account and the Treasury Note Account will be paid by Commerce in a single distribution as soon as reasonably practicable after retirement, disability, death or termination of employment, except that a participant may elect to have distributions from such accounts made in up to ten annual equal installments or in such installments after receiving a lump sum payment of a portion of the account balances. Annual installments will be paid in an amount, less applicable withholding taxes, determined by multiplying the balance in either account by a fraction, the numerator of which is one (1) and the denominator of which is a number equal to remaining unpaid annual installments. (2) If a participant dies after the commencement of payments from such participant's Treasury Bill Account or Treasury Note Account, the designated beneficiary shall receive the remaining installments over the elected installment period. (3) With respect to a participant's Commerce Stock Account, upon such participant's employment terminating for disability, death, retirement, or termination of employment, the whole units in the participant's Commerce Stock Account shall be converted into shares of Commerce Stock with each whole unit representing one share of such stock with cash paid in lieu of any fractional shares. No distribution, however, shall be made from the Commerce Stock Account until arrangements satisfactory to Commerce shall have been made to provide for the payment to Commerce of federal, state, local, and payroll withholding taxes attributable to the Commerce Stock Account. (4) Each participant shall have the right at any time to designate any person or persons as beneficiary or beneficiaries (both principal as well as contingent) to whom payment under this Plan shall be made in the event of death prior to complete distribution to the participant of the amounts due under this Plan. Any beneficiary designation may be changed by a participant by the filing of such change in writing on a form prescribed by Commerce. The filing of a new beneficiary designation form will cancel all beneficiary designations previously filed and will apply to all deferrals in the account. If a beneficiary has not been designated or if all designated beneficiaries predecease the participant, then any amounts payable to the beneficiary shall be paid to the participant's estate in one lump sum. (5) If there is any change in the number or class of shares of Commerce stock through the declaration of stock dividend or other extraordinary dividends or recapitalization resulting in stock splits or combinations or exchanges of such shares or in the event of similar corporate transactions, each participant's Commerce Stock Account shall be equitably adjusted to reflect any such change in the number or class of issued shares of common stock of Commerce or to reflect such similar corporate transaction. (6) The Human Resources/Salary Committee of Commerce, upon 30 days written notice, may approve a "hardship" request for distribution of a deferred award. Unless the participant presents proof satisfactory to such committee of financial need, requests for hardship distribution will be denied. Each request will be evaluated on the basis of uniformly applied criteria. 7. AMENDMENT AND TERMINATION OF PLAN The Board of Directors may at its discretion and at any time amend the Plan in whole or in part. The Committee may terminate the Plan in its entirety at any time, and, upon such termination or such later date or dates, each participant shall: receive, in a single distribution, the shares and cash for the fractions thereof of Commerce Stock reflected in the Commerce Stock Account; and shall be paid, in a single distribution or over such period of time as determined by the Committee, the then remaining balance in such participant's Treasury Bill Account and Treasury Note Account. 8. MISCELLANEOUS a. A participant under this Plan is merely a general unsecured creditor and nothing contained in this Plan shall create a trust of any kind or a fiduciary relationship between Commerce and the participant or the participant's estate. Nothing contained herein shall be construed as conferring upon the participant the right to continued employment with Commerce or its subsidiaries or to an incentive compensation award. Except as otherwise provided by applicable law, benefits payable under this Plan may not be assigned or hypothecated, and no such benefits shall be subject to legal process or attachment for the payment of any claim of any person entitled to receive the same. b. The amendment of the Plan to allow a Commerce Stock deferral option shall become effective on the date the shareholders of Commerce approve the same. Subject to such approval, an employee having a deferred option may elect (but prior to June 30, 1994) to transfer his balance in the Treasury Bill Account and/or the Treasury Note Account as of April 1, 1994 to the Commerce Stock Account with the number of units credited to his account determined as provided in Section 6d hereof but based on the last sale price as of the last day in March 1994 on which a trade of Commerce Stock is reported. An employee who in 1993 deferred a potential incentive compensation award with respect to performance in 1994 and elected either a Treasury Bill Account or a Treasury Note Account may elect prior to June 30, 1994 to defer such award for 1994 to the Common Stock Account.
