 9.
Assignment of Award. Except as otherwise permitted by the Committee and as provided in the immediately following paragraph, the Participant’s rights under the Plan and this Agreement are personal, and no assignment or transfer of the
Participant’s rights under and interest in this Award may be made by the Participant other than by a domestic relations order. This Award is payable during his lifetime only to the Participant, or in the case of the Participant being mentally
incapacitated, this Award shall be payable to his guardian or legal representative. 
 The Participant may designate a
beneficiary or beneficiaries (the “Beneficiary”) to whom the Award under this Agreement, if any, will pass upon the Participant’s death and may change such designation from time to time by filing with the Company a written designation
of Beneficiary on the form attached hereto as Exhibit A, or such other form as may be prescribed by the Committee; provided that no such designation shall be effective unless so filed prior to the death of the Participant and no such designation
shall be effective as of a date prior to receipt by the Company. The Participant may change his Beneficiary without the consent of any prior Beneficiary by filing a new designation with the Company. The last such designation that the Company
receives in accordance with the foregoing provisions will be controlling. Following the Participant’s death, the Award, if any, will pass to the designated Beneficiary and such person will be deemed the Participant for purposes of any
applicable provisions of this Agreement. If no such designation is made or if the designated Beneficiary does not survive the Participant’s death, the Award shall pass by will or, if none, then by the laws of descent and distribution.

 10. Withholding. The Company’s obligations under this Agreement shall be subject to the satisfaction of all
applicable tax withholding requirements including those related to federal, state and local income and employment taxes (the “Required Withholding”). The Company may withhold an appropriate amount of cash (with respect to the payment of
dividend equivalents) or number of shares from the Common Stock that would otherwise have been delivered to the Participant (with respect to the settlement of the Award) necessary to satisfy the Participant’s Required Withholding, and deliver
the remaining amount of cash or shares of Common Stock to the Participant, unless the Participant has made arrangements with the Company for the Participant to deliver to the Company cash, check, other available funds or shares of previously owned
Common Stock for the full amount of the Required Withholding by 5:00 p.m. Central Standard Time on the date an amount is included in the income of the Participant. The amount of the Required Withholding and the number of shares to satisfy the
Participant’s Required Withholding shall be based on the Fair Market Value of the shares on the date prior to the applicable date of income inclusion.

 11. Stock Certificates. Any certificates representing the Common Stock issued
pursuant to the settlement of an Award will bear all legends required by law and necessary or advisable to effectuate the provisions of the Plan and this Award. The Company may place a “stop transfer” order against shares of the Common
Stock issued pursuant to this Award until all restrictions and conditions set forth in the Plan or this Agreement and in the legends referred to in this Section 11 have been complied with. 

12. Successors and Assigns. This Agreement shall bind and inure to the benefit of and be enforceable by the Participant, the
Company and their respective permitted successors and assigns (including personal representatives, heirs and legatees), except that the Participant may not assign any rights or obligations under this Agreement except to the extent and in the manner
expressly permitted in Section 9 of this Agreement. 
 13. No Service as Chairman Guaranteed. No provision of this
Agreement shall confer any right upon the Participant to serve as Chairman. 
 14. Code Section 409A Compliance.
