(4)           5:00 p.m. United States Central Time on the Grant Expiration Date.

5.             No Fractional Shares.  This Stock Option may be exercised only in whole Shares and not fractional Shares.  Any fraction of a Share that would otherwise vest on any vesting date will be rounded down to the nearest whole Share.

6.             Manner of Exercise.  Before the end of the Option Period, this Stock Option may be exercised only by Participant (or by Participant’s guardian or legal representative, or by Participant’s estate (if Participant is deceased)) up to the extent then vested and exercisable by delivering to the Company’s stock option administrator an irrevocable notice of exercise in the form required by the Company.  The notice of exercise shall state the number of Shares for which the Option is being exercised and shall be accompanied by payment in full of the Grant Price for those Shares (under Section 7 below) and applicable tax withholdings (under Section 10 below).

7.             Payment of Grant Price.  Participant may pay the Grant Price by wire transfer or check (bank check, certified check or personal check) or by delivering to the Company for cancellation, in accordance with the rules of the Committee, shares of Common Stock which have a Fair

4

Market Value in United States dollars equal to the Grant Price and which either (i) were purchased on a national stock exchange or on the NASDAQ NMS system or (ii) have been issued and outstanding more than six months.  The Grant Price is payable in United States dollars.  Subject to the Company’s approval, Participant may also pay the Grant Price by having it delivered to the Company in cash from a broker, dealer or other “creditor” as defined in Regulation T issued by the Board of Governors of the Federal Reserve System following delivery by the Participant to the Company of instructions in a form acceptable to the Company regarding delivery to such broker, dealer or other creditor of that number of shares of Common Stock with respect to which the Stock Option is exercised.

8.             Delivery of Shares.  The Company will deliver to Participant the Shares (either in certificate or electronic form as requested by Participant) promptly after proper exercise of the Option and receipt of the Grant Price and applicable tax withholdings.  Notwithstanding any provision in this Agreement to the contrary, the obligation of the Company to deliver Shares is subject to the condition that if at any time the Committee shall determine in its discretion that the listing, registration, or qualification of the Stock Option or the Shares upon any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body, is necessary as a condition of, or in connection with, the Stock Option or the issuance or purchase of Shares thereunder, then the Stock Option may not be exercised in whole or in part unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not reasonably acceptable to the Committee.

9.             Tax Requirements for Incentive Stock Options; Disqualifying Disposition.  This Section 9 will apply only if this Stock Option is identified as an Incentive Stock Option or ISO on the Certificate.  If this Section 9 applies, then subject to the provisions of the Plan, this Stock Option is an Incentive Stock Option.  To the extent the number of Shares exceeds the limit set forth in Section 4 of the Plan, such Shares shall be deemed granted pursuant to a Nonqualified Stock Option.  In such event, then unless otherwise indicated by Participant in the notice of exercise pursuant to Section 6 above, upon any exercise of this Stock Option, the number of exercised Shares that shall be deemed to be exercised pursuant to an Incentive Stock Option shall equal the total number of Shares so exercised multiplied by a fraction, (a) the numerator of which is the number of unexercised Option Shares that could then be exercised pursuant to an Incentive Stock Option and (b) the denominator of which is the then total number of unexercised Option Shares that could then be exercised.  If Common Stock acquired upon exercise of this Stock Option is disposed of by Participant in a “Disqualifying Disposition,” such Participant shall notify the Company in writing within 30 days after such disposition of the date and terms of such disposition.  For purposes hereof, “Disqualifying Disposition” means a disposition of Common Stock that is acquired upon the exercise of an Incentive Stock Option prior to the expiration of either two years from the Grant Date of such Incentive Stock Option or one year from the transfer of Shares to Participant pursuant to the exercise of such Incentive Stock Option.  If a Disqualifying Disposition occurs, the tax requirements described in Section 10 will apply.

10.           Tax Requirements and Withholdings for Nonqualified Stock Options.  This Section 10 will apply only if this Stock Option is identified as a Nonqualified Stock Option or NQ on the Certificate or is considered a Nonqualified Stock Option under Section 9 above.  In order to provide the Company and its Subsidiaries with the opportunity to claim the benefit of any income tax deduction in any jurisdiction which may be available to it upon the exercise of the Nonqualified Stock Option, and in order to comply with all applicable income tax laws or regulations of any applicable country, state or other jurisdiction, the Company and its

5

Subsidiaries may take such action as it deems appropriate to ensure that, if necessary, all applicable payroll, withholding, income, NIC or other taxes (of any applicable country, state or other jurisdiction) are withheld or collected from Participant.  Participant may elect to satisfy Participant’s minimum income tax withholding obligations under such laws or regulations upon exercise of the Option by (i) paying that amount by wire transfer or check (bank check, certified check or personal check), (ii) having the Company or its Subsidiaries withhold a portion of the shares of Shares otherwise to be delivered upon exercise of such Option having a Fair Market Value in United States dollars (on the date of exercise of Option) equal to the minimum amount of such taxes required to be withheld on such exercise, in accordance with the rules of the Committee, or (iii) delivering to the Company for cancellation, in accordance with the rules of the Committee, shares of Common Stock which have a Fair Market Value equal to such tax withholdings and which either (a) were purchased on a national stock exchange or on the NASDAQ NMS system or (b) have been issued and outstanding more than six months.  The Company may, at its discretion, require Participant to pay the withholding taxes under clause (i) above in lieu of the alternatives in clauses (ii) or (iii) above.

11.           Investment Representation.  Unless the Common Stock is issued to Participant in a transaction registered under applicable federal and state securities laws, Participant represents and warrants to the Company that all Common Stock which may be purchased hereunder will be acquired by Participant for investment purposes for Participant’s own account and not with any intent for resale or distribution in violation of federal or state securities laws.  Unless the Common Stock is issued to Participant in a transaction registered under the applicable federal and state securities laws, all certificates issued with respect to the Common Stock shall bear an appropriate restrictive investment legend.

12.           Impact on Employment Status.  This Agreement, the Certificate and the Plan are not an employment contract.  Nothing contained in this Agreement, the Certificate or the Plan shall confer on Participant any right to continue in the employ of the Company or any Subsidiary or other affiliate of the Company or affect in any way the right of the Company or any Subsidiary or other affiliate to terminate the employment of Participant at any time.

13.           Adjustments.  In the event of any stock split, stock dividend, recapitalization or combination of shares by the Company after the Grant Date, the number of Shares subject to the Option and the Grant Price per Share shall be equitably adjusted in the same manner as the outstanding shares of Common Stock, in accordance with the rules of the Committee.  The number of Option Shares designated in the Certificate has been adjusted for all stock splits that were effective before the Grant Date.

14.           Non-Transferability of Option.  This Stock Option is not assignable or transferable by Participant except by will or by the laws of descent and distribution.

15.           Consent to Internal Use of Personal Data.  Participant consents to the Company’s and its Subsidiaries’ (and the Company’s stock option administrator) receiving and using personal data related to Participant for employment-related purposes only and for gathering and making required reports to government authorities.

15.           No Right of Future Stock Option Grants.  Nothing contained in this Agreement, the Certificate or the Plan shall confer on Participant any right to receive any additional stock options in the future from the Company, Subsidiary or any other affiliate of the Company or affect in any

6
