iii.The Participant must remain in Continuous Service through the vesting date. For purposes of the Agreement, “Continuous Service” shall mean the Participant’s service with the Company or any Subsidiary or Affiliate as an employee, or the Participant’s service as a member of the Board of Directors of the Company, has not been interrupted or terminated, and shall include any period during which the Participant is on an approved leave of absence from the Company or its Subsidiaries or Affiliates. Except as set forth in Section 3(b), upon the Participant’s termination of Continuous Service prior to the vesting date, the terms of Section 7 shall apply.

b.Notwithstanding the terms of Section 3(a) above, if the Participant’s Continuous Service is terminated as a result of the Participant’s death or Disability, the target number of PSUs granted to the Participant under the Agreement will immediately vest.

c.In the case of a Participant who is both an employee of the Company or any Subsidiary or Affiliate and a member of the Board of Directors of the Company, Continuous Service shall not end until the Participant’s service as both an employee and a director terminates.

4.Change in Control. The PSUs are subject to the Change of Control provisions as set forth in detail in the Plan.

5.Characteristics of PSUs.

a.PSUs are not Shares and the grant of a target number of PSUs shall provide only those rights expressly set forth in the Agreement and the Program. The Participant is not deemed to be a stockholder in the Company or have any of the rights of a stockholder in the Company by virtue of the grant of PSUs.

b.The Participant does not have voting rights or any other rights inherent to the ownership of Shares, including the rights to dividends (other than as provided in Section 10), or other liquidating or non-liquidating distributions, by virtue of being granted PSUs.

c.Neither the PSUs nor any right hereunder or under the Program shall be transferable or be subject to attachment, execution or other similar process. In the event of any attempt by the Participant to alienate, assign, pledge, hypothecate or otherwise dispose of the PSUs or of any right hereunder or under the Program, except as provided for in the Program, or in the event of any levy or any attachment, execution or similar process upon the rights or interest conferred by the PSUs, the Company may terminate the PSUs by notice to the Participant and the PSUs and any related rights, including the right to dividend equivalents as described in Section 10, shall thereupon be cancelled.

6.Effect of Vesting.

a.If, and at the time, the Participant’s PSUs vest under the terms of Section 3 or Section 4, such Participant shall receive as full consideration for the PSUs a number of Shares equal to the number of PSUs which vested on such date.

b.The PSUs granted to the Participant shall be maintained in a bookkeeping account with the custodian appointed by the Committee from time to time (the “Custodian”) for such Participant if and until the PSUs are converted into Shares pursuant to this Section 6, at which time the Shares shall be issued to the Participant in accordance with Section 9 below.

7.Forfeiture of PSUs. Subject to the next following sentence, the Participant’s PSUs shall be forfeited to the Company upon the Participant’s termination of Continuous Service with the Company and its Subsidiaries and Affiliates (a) for any reason other than the Participant’s death or Disability that occurs prior to the date the PSUs vest as provided in Section 3 above or (b) for any reason other than the Participant’s termination by the Company without Cause or the Participant’s voluntary termination due to the existence of Good Reason, in either case during the two-year period beginning on the date of a Change in Control, as provided in Section 4 above. The foregoing provisions of this Section 7 shall be subject to the provisions of the Company’s Bonus, Restricted Stock Unit, Performance Stock Unit and Bonus Cash Deferral Retirement Policy (the “Retirement Policy”), and any other Company plan or written employment, severance or similar agreement that has been or may be executed by the Participant and the Company, and the provisions in such Retirement Policy or agreement concerning the vesting of the PSUs in connection with the Participant’s termination of Continuous Service shall supersede any inconsistent or contrary provision of this Section 7.

8.Compensation Recovery. The Participant’s PSUs are subject to the Clawback Policy adopted by the Board of Directors.

9.Delivery of Shares to the Participant. As soon as practicable after the PSUs vest and are converted into Shares, and subject to Section 11, the Custodian shall, without transfer or issue tax or other incidental expense to the Participant, deliver to the Participant by first-class insured mail addressed to the Participant at the address shown on page 1 or the last address of record on file with the Custodian, (a) a statement from the Custodian referencing the number of Shares held in the Participant’s name in a book entry account, or (b) at the Participant’s request, certificate(s) for the number of Shares as to which the PSUs vested. In any event, Shares due the Participant shall be delivered as described above no later than March 15 of the year following the calendar year in which such PSUs vest.

10.Dividend Equivalents. The Company shall credit the Participant’s PSU account with an amount equal to the dividends, if any, that would be paid with respect to the unvested PSUs as if the PSUs were actual Shares to a shareholder as of the Record date. Such amount shall be credited to the Participant’s PSU account at the same time dividends are paid with respect to the Shares, shall be subject to the vesting and forfeiture provisions set forth in Sections 3, 4 and 7 of the

Agreement, and shall be paid to the Participant in cash, on the first payroll date following the date the Participant’s related PSUs vest and are issued as Shares to the Participant.

11. Tax Withholdings and Payments.

a.The Company or any Subsidiary or Affiliate is authorized to withhold from any payment to be made to the Participant, amounts of income tax withholding and other taxes due in connection with compensation or any other transaction under the Program, including the receipt of Shares under Section 6. The Participant shall hold the Company harmless for any damages caused by his or her failure to so comply and for any other damages caused by his or her actions or inactions.

b.The Participant may pay withholding taxes attributable to the receipt of Shares in cash, by having Shares withheld by the Company from any Shares that would otherwise be received by the Participant under the Agreement (in which case, the number of Shares so withheld shall have an aggregate Fair Market Value at the time of such withholding sufficient to satisfy the applicable withholding taxes), or by any other method approved by the Committee. If the Participant does not satisfy the withholding obligation by cash payment within a reasonable time established by the Committee, the Participant’s withholding obligation shall be satisfied by the Company’s withholding of Shares from the vested PSUs.

c.The Company shall deduct from the dividend equivalents paid to the Participant pursuant to Section 10 the Participant’s withholding obligation arising from such payment.

12.Miscellaneous.

a.The granting of an Award under the Program and the Agreement shall impose no obligation on the Company or any Subsidiary or Affiliate to continue the employment relationship or any other relationship between it and the Participant and shall not lessen or affect the Company’s, Subsidiary’s or Affiliate’s right to terminate its relationship with the Participant. The Participant shall have no claim to be granted any further or other Award under the Program, and there is no obligation for uniformity of treatment of the Participants. The Participant acknowledges and agrees that: (i) the Program is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time; (ii) the grant of PSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of PSUs, or benefits in lieu of PSUs, even if PSUs have been granted repeatedly in the past; (iii) all decisions with respect to future PSU grants, if any, will be at the sole discretion of the Company; (iv) participation in the Program is voluntary; (v) the PSUs are not a part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments; (vi) the future value of the underlying shares is unknown and cannot be predicted with certainty; and (vii) in consideration of the grant of PSUs, no claim or entitlement to compensation or damages shall arise from termination of the PSUs or diminution in value of the PSUs or Shares received upon vesting including (without limitation) any claim or entitlement resulting from termination of the Participant’s active employment by the Company or a Subsidiary or Affiliate (for any reason whatsoever and whether or not in breach of local labor laws) and the Participant hereby releases the Company and its Subsidiaries and Affiliates from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by signing this Agreement, the Participant shall be deemed irrevocably to have waived the Participant’s entitlement to pursue such claim.

b.The Agreement shall, subject to the terms hereof, terminate upon the forfeiture and/or vesting of all PSUs and dividend equivalents granted to the Participant hereunder, unless otherwise agreed upon by the parties hereto.

c.The Agreement may be amended by the written agreement of the Company and the Participant. Notwithstanding the foregoing, (i) the Company may amend, alter or discontinue the Agreement, without the consent of the Participant so long as such amendment, alteration or discontinuance would not impair any of the rights or obligations under any Award theretofore granted to the Participant under the Program; and (ii) the Committee may amend the Agreement in such manner as it deems necessary to permit the granting of Awards meeting the requirements of the Code or other applicable laws.

d.The parties agree that the Agreement shall be governed by and interpreted and construed in accordance with the laws of the United States and, in particular, those of the State of Illinois without regard to its conflict of law principles, as Illinois is the situs of the principal corporate office of the Company. Furthermore, to the extent not prohibited under applicable law, and unless the Company affirmatively elects in writing to allow the proceeding

to be brought (or itself brings such a proceeding) in a different venue, the parties agree that any suit, action or proceeding with respect to the Program, the PSUs or the Agreement shall be brought in the state courts in Chicago, Illinois or in the U.S. District Court for the Northern District of Illinois. The parties hereby accept the exclusive jurisdiction of those courts for the purpose of any such suit, action or proceeding. Venue for any such action, in addition to any other venue required or otherwise mandated by statute, will be in Chicago, Illinois. Each party further agrees to waive any applicable right to a jury trial, and expressly elects to have the matter heard as a bench trial.

e.Unless waived by the Company, any notice to the Company required under or relating to the Agreement shall be in writing and addressed to:

General Counsel & Corporate Secretary

13.Program Governs. All terms and conditions of the Program are incorporated herein and made part hereof as if stated herein.

The Participant may, at any time, review Data, require any necessary amendments to it or withdraw the consents herein in writing by contacting the Company; however, by withdrawing consent, the Participant will affect his or her ability to participate in the Program.
