Termination (Other Than Death or Permanent Disability). 6.5.1. In the event that an Optionee holding an Incentive Stock Option should cease to be employed by the Company for any reason (including Retirement) other than death or permanent disability, the Incentive Stock Option may be exercised at any time within three (3) months after the termination of employment (but in no event after the expiration of the 4 option period) if and to the extent it was exercisable as of the date of termination and had not previously been exercised. Notwithstanding the foregoing, if an Optionee's employment is terminated voluntarily by the Optionee (other than due to Retirement) or is terminated because of the Optionee's dishonesty, theft, embezzlement from the Company, willful violation of any rules of the Company pertaining to the conduct of Employees or the commission of a willful felonious act while an Employee, then any Incentive Stock Option or unexercised portion thereof granted to said Optionee shall expire upon termination of employment. 6.5.2. In the event that an Optionee holding a Nonqualified Stock Option should cease to be employed by the Company for any reason other than Retirement, death or permanent disability, then the Nonqualified Stock Option may be exercised within a period of not more than three (3) months after the termination of employment (but in no event after the expiration of the option period), if and to the extent it was exercisable as of the date of termination and had not previously been exercised. If an Optionee holding a Nonqualified Stock Option shall cease to be an Employee by reason of Retirement, the Optionee shall have the right to exercise the Nonqualified Stock Option with respect to all or any part of the Shares as to which such Nonqualified Stock Option remained unexercised within a period of not more than thirty-six (36) months from the date such Optionee ceased to be an Employee (but in no event after the expiration of the Nonqualified Stock Option period), if and to the extent it was exercisable as of the date of termination and had not previously been exercised. Notwithstanding the foregoing, if an Optionee's employment is terminated voluntarily by the Optionee other than due to Retirement or is terminated because of the Optionee's dishonesty, theft, embezzlement from the Company, willful violation of any rules of the Company pertaining to the conduct of Employees or the commission of a willful felonious act while an Employee, then any Nonqualified Stock Option or unexercised portion thereof granted to said Optionee shall expire upon termination of employment. 6.6. If an Optionee shall die and shall not have fully exercised his Option, the Option may be exercised as follows, if and to the extent it was exercisable as of the date of death and had not previously been exercised: 6.6.1. With respect to an Incentive Stock Option, if the Optionee died while an Employee, the Incentive Stock Option may be exercised at any time within one (1) year after the Optionee's death by the executors or administrators of the Optionee or by any person or persons who shall have acquired the Incentive Stock Option directly from the Optionee by bequest or inheritance. 5 6.6.2. With respect to a Nonqualified Stock Option, if the Optionee died while an Employee, or within twelve (12) months after the date of termination of such employment due to disability (as described in Section 6.7.2 below) or Retirement (as described in Section 6.5.2 above), the Nonqualified Stock Option granted to the Optionee shall be exercisable with respect to all or any part of the Shares as to which such Nonqualified Stock Option remains unexercised by the Optionee's legal representative or other person or persons to whom the Optionee's rights under the Nonqualified Stock Option shall pass by the Optionee's will or the laws of descent and distribution, but only before the expiration of the Nonqualified Stock Option period or of the twelve (12) month period next succeeding the Optionee's death, whichever first occurs. 6.7. If an Optionee shall cease to be an Employee by reason of a permanent disability (as determined by the Optionee officially establishing his eligibility to receive Social Security disability benefits), the Optionee may exercise his Option as follows, if and to the extent it was exercisable as of the date the Optionee ceased to be an Employee by reason of such a permanent disability, and had not previously been exercised: 6.7.1. An Incentive Stock Option may be exercised at any time within one (1) year from the date such Optionee ceased being an Employee. 6.7.2. A Nonqualified Stock Option may be exercised with respect to all or any part of the Shares within a period of not more than thirty-six (36) months from the date such Optionee ceased to be an Employee (but in no event after the expiration of the Nonqualified Stock Option period). 6.8. The fair market value of Common Stock for which any Incentive Stock Option may be granted in any calendar year under the Plan shall be in such amount as the Committee shall determine; provided, however, that the aggregate fair market value of Common Stock for which Incentive Stock Options granted under the Plan (or any other incentive stock option plan of the Company or any subsidiary) first become exercisable in any one calendar year by an Optionee may not exceed $100,000 (determined as of the date of grant). SECTION VII EXERCISE OF OPTION 7.1. An Option shall be deemed to be exercised when written notice of such exercise has been received by the Company in accordance with the terms of the Option by the person entitled to exercise the Option, and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Payment may be made (i) in cash, (ii) by delivering Common Stock of the Company already owned by the Optionee, or (iii) a combination of cash and Common Stock. The fair market value of Common Stock delivered for payment shall be the last sale price as reported by the Automated Quotation System of the National Association of Securities Dealers on the date of exercise. No shares shall be issued, delivered, or recorded on the records of the Company or its transfer agents or registrars until full 6 payment therefore has been made. Until the issuance of the stock certificates or entry on the records of the Company or its transfer agents or registrars is made, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Shares as to which the Option has been exercised. No adjustment will be made for a dividend or other rights for which a record date is established prior to the date the stock certificates are issued or record entry is made, except as provided in Section 8.1 of the Plan. 7.2. At the time of exercise of a Nonqualified Stock Option granted under this Plan, the Optionee shall provide for the payment to the Company of federal, state, local and payroll withholding taxes attributable to such exercise. The Optionee shall advise the Company at the time of exercise of the amount of desired withholding but such withholding may not be less than the minimum required by law, which minimum amount shall be withheld in the absence of other instruction from the Optionee. The Optionee may direct the Company to withhold from the exercise of the Nonqualified Stock Option that number of whole shares of Common Stock as shall equal in value the nearest whole share equivalent of the indicated tax withholding requirement. Shares to be used for withholding shall be valued at the last sale price as reported by the Automated Quotation System of the National Association of Securities Dealers on the date of exercise. To the extent the withholding amount is not satisfied in Shares, the Optionee shall satisfy the remaining amount to be withheld by remitting such amount in cash to the Company contemporaneously with the exercise of the Option. 7.3. Notwithstanding any other provision of this Plan, the Committee may postpone any exercise of an Option for such period as the Committee in its discretion may deem necessary in order to permit the Company (i) to effect or maintain registration of the Plan or the Shares issuable upon the exercise of an Option under the Securities Act of 1933, as amended, or the securities laws of any applicable jurisdiction, (ii) to permit any action to be taken in order to comply with restrictions or regulations incident to the maintenance of a public market for its Shares or to list the Shares thereon; or (iii) to determine that such Shares and the Plan are exempt from such registration or that no action of the kind referred to in (ii) above need be taken; and the Company shall not be obligated by virtue of any terms and conditions of any Option Grant or any provision of the Plan to permit the exercise of an Option to sell or deliver Shares in violation of the Securities Act of 1933 or other applicable law. Any such postponement shall not extend the term of an Option and neither the Company nor its directors or officers or any of them shall have any obligation or liability to the Optionee or to any other person with respect to any Shares as to which an Option shall lapse because of such postponement. SECTION VIII REORGANIZATION, CHANGE IN CONTROL 8.1. If the Shares shall be changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation (whether by reason of merger, consolidation, recapitalization, reclassification, split-up, combination of shares, or otherwise), or if the number of such Shares shall be increased through the payment of a stock dividend or stock split, there shall be substituted for or added to each Share theretofore reserved 7 for the purposes of the Plan, whether or not such Shares are at the time subject to outstanding Options, the number and kind of shares of stock or other securities into which each outstanding Share shall be so changed or for which it shall be so exchanged, or to which each such Share shall be entitled, as the case may be. Outstanding Options shall also be considered to be appropriately amended as to price and other terms as may be necessary or appropriate to reflect the foregoing events. If there shall be any other change in the number or kind of the outstanding Shares, or of any stock or other securities into which such Common Stock shall have been changed, or for which it shall have been exchanged, then if the Board of Directors shall in its sole discretion determine that such change equitably requires an adjustment in the number or kind or option price of the Shares then reserved for the purposes of the Plan, or in any Option theretofore granted or which may be granted under the Plan, such adjustment shall be made by the Board of Directors and shall be effective and binding for all purposes of the Plan. In making any such substitution or adjustment pursuant to this Section 8.1, fractional shares shall be ignored. 8.2. Notwithstanding any other provision of the Plan to the contrary, in the event of a Change in Control, Options outstanding as of the date of such Change in Control and not then exercisable and vested shall become fully exercisable and vested. For purposes of the Plan, a "Change in Control" shall mean the happening of any of the following events: (a) any Person is or becomes the "beneficial owner" (within the meaning of Rule 13d-3 promulgated under Section 13 of the Securities Exchange Act of 1934 (the "Exchange Act")), directly or indirectly, of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its affiliates other than in connection with the acquisition by the Company or its affiliates of a business) representing 20% or more of either the then outstanding shares of common stock of the Company or the combined voting power of the Company's then outstanding securities; or (b) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, on August 2, 1996, constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors on August 2, 1996 or whose appointment, election or nomination for election was previously so approved; or 8 (c) there is consummated a merger or consolidation of the Company (or any direct or indirect subsidiary of the Company) with any other corporation, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company, at least 80% of the combined voting power of the voting securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person is or becomes the beneficial owner, directly or indirectly, of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its subsidiaries other than in connection with the acquisition by the Company or its subsidiaries of a business) representing 20% or more of either the then outstanding shares of common stock of the Company or the combined voting power of the Company's then outstanding securities; or (d) the stockholders of the Company approve (i) a plan of complete liquidation or dissolution of the Company or (ii) a sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 80% of the combined voting power of the voting securities of which are owned by Persons in substantially the same proportions as their ownership of the Company immediately prior to such sale. For purposes of the above definition of Change in Control, "Person" shall have the meaning set forth in Section 3(a)(9) of the Exchange Act, as modified and used in Sections 13(d) and 14(d) thereof, except that such term shall not include (i) the Company or any of its subsidiaries, (ii) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any of its subsidiaries, (iii) an underwriter temporarily holding securities pursuant to an offering of such securities, or (iv) a corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company. 8.3. In the event of a Change in Control under Section 8.2(c) or (d)(ii) (a "Section 8.3 Event") the Committee shall have the discretion (a) to arrange for the successor to assume each outstanding Option, (b) to arrange for the substitution of outstanding Options with equivalent awards by the successor corporation or a parent or subsidiary of the successor corporation, (c) to terminate each outstanding Option in exchange for payment of an amount based on a price not less than the fair market value of the consideration (whether stock, cash, or other securities or 9 property) received or to be received in the Section 8.3 Event by holders of each Share of common stock held on the effective date of the transaction (and if holders of Shares were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares), less the exercise price with respect to the Option, or (d) to take such other action with respect to the Option as determined by the Committee in its sole discretion. SECTION IX AMENDMENT AND TERMINATION OF PLAN 9.1. The Board may amend the Plan from time to time as it deems desirable and shall make any amendments which may be required so that Options intended to be Incentive Stock Options shall at all times continue to be Incentive Stock Options for purposes of the Internal Revenue Code. 9.2. This Plan shall terminate on December 31, 2005, provided that the Board may in its discretion terminate this Plan at any time prior thereto. 9.3. Any amendment to or the termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated. 9.4. This Plan is effective on January 1, 1996, and Options hereunder may be granted thereafter, subject to the terms of the Plan, provided this Plan is approved by a vote of the holders of a majority of the outstanding shares of the Company at a meeting of shareholders of the Company held within twelve (12) months following the adoption date. 9.5. This Plan shall be interpreted and construed in accordance with the laws of the State of Missouri. 10
