Name:    [Name]

By:     

    NOW, THEREFORE, in consideration of the agreements of the Participant herein provided and pursuant to the Program, the parties agree as follows:

1.Definitions. All capitalized terms used herein, unless specifically defined herein, shall have the same meanings as established in the Program.

2.Participation. Contingent upon the execution of the Agreement, the Company hereby grants to the Participant [_____] RSUs subject to the terms and conditions herein.

3.Vesting of RSUs.

a.Subject to Section 3(b) and Section 9 below, all RSUs granted under the Agreement shall vest in accordance with the schedule set forth below; provided the Participant has been in Continuous Service through each vesting date. 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 10 shall apply. 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; provided, however, a change in the status in which the Participant renders service to the Company or its Subsidiaries or Affiliates or a change in the entity for which the Participant renders such service shall not constitute an interruption or termination of the Participant’s employment or service for purposes of this Agreement, so long as there is no interruption or termination of the Participant’s services to the Company or its Subsidiaries or Affiliates; provided, further, that if the entity employing or engaging the Participant ceases to be an Affiliate of the Company, the Participant’s employment or service shall be considered to have terminated on the date such entity ceased to be an Affiliate.

b.If the Participant’s Continuous Service is terminated as a result of the Participant’s death or termination by the Company due to Disability, all RSUs 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.Effect of Vesting.

a.If, and at the time, the Participant’s RSUs vest under the terms of Section 3 or Section 9, and subject to the terms of this Agreement, such Participant shall receive as full consideration for the RSUs a number of Shares equal to the number of RSUs which vested on such date.

b.The RSUs granted to the Participant shall be maintained in a bookkeeping account with the custodian appointed by the Human Resources & Compensation Committee of the Board (the “Committee”) from time to time (the “Custodian”) for such Participant if and until the RSUs are converted into Shares pursuant to this Section 4, at which time the Shares shall be issued to the Participant in accordance with Section 5 below.

5.Delivery of Shares to the Participant. As soon as practicable after the RSUs vest and are converted into Shares, and subject to the terms of this Agreement, 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, (i) a statement from the Custodian referencing the number of Shares held in the Participant’s name in a book entry account, or (ii) at the Participant’s request, certificate(s) for the number of Shares as to which the Shares vested. In any event, Shares due to the Participant shall be delivered as described above no later than March 15 of the year following the calendar year in which such RSUs vest.

6.Compensation Recovery. The Participant’s RSUs are subject to any clawback or recoupment policies in effect as of the Grant Date or which the Company may amend or adopt from time to time to comply with applicable law or listing standard.

7.Dividend Equivalents. The Company shall credit the Participant’s RSU account with an amount equal to the dividends, if any, that would be paid with respect to the unvested RSUs as if the RSUs were actual Shares to a shareholder as of the record date. Such amount shall be credited to the Participant’s RSU 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, 9 and 10 of the Agreement, and shall be paid to the Participant in cash, on the first payroll date following when the Participant’s related RSUs vest and are issued as Shares to the Participant or settled in cash, or as soon as practical thereafter (but in any event no later than March 15 of the year following the calendar year in which such RSUs vest).

8.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 under this Agreement with respect to the RSUs, 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 5. The Participant shall hold the Company and its Subsidiaries and Affiliates 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 will 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 RSUs.

c.The Company shall deduct from the dividend equivalents paid to the Participant pursuant to Section 7 the Participant’s withholding obligation arising from such payment.

9.Change in Control. The RSUs are subject to the Change of Control provisions as set forth in detail in the Program.

10.Forfeiture of RSUs.

a.Subject to Section 10(b), the Participant’s unvested RSUs shall be forfeited to the Company upon the Participant’s termination of Continuous Service with the Company and its Subsidiary and Affiliates for any reason other than (a) the Participant’s death or termination by the Company due to Disability that occurs prior to the date the RSUs vest as provided in Section 3 above; (b) the Participant’s termination of Continuous Service by the Company or any Subsidiary or Affiliate 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 9 above; or (c) in the case of the Chief Executive Officer and/or Tier I Participants, in the event of the Participant’s termination of Continuous Service by the Company without Cause as outlined in the Company’s Management Severance Pay Plan (the “Severance Pay Plan”).

b.This Section 10 shall be subject to the provisions of the Retirement Policy in effect as of the Grant Date and any subsequent amendments thereto applicable to

this Agreement, and any other Company plan or written employment, severance or similar agreement in effect as of the Grant Date between the Participant and the Company, and the provisions in such Retirement Policy or agreement concerning the vesting of RSUs in connection with the Participant’s termination of Continuous Service shall supersede any inconsistent or contrary provision of this Section 10.

c.Subject to applicable law and the Retirement Policy, and to the extent the Participant is eligible for time-based vesting under the terms of the Retirement Policy, Participant shall forfeit all outstanding RSUs awarded hereunder if Participant engages in any of the non-competition, non-solicitation, and/or non-disparagement obligations set forth in Section IV of the Retirement Policy.

d.This Section 10 does not constitute the Company’s exclusive remedy for the Participant’s violation of any post-employment obligations owed to the Company, including but not limited to any obligations of confidentiality, or restrictive covenants that may exist in the Participant’s employment agreement, where applicable.

e.The Participant acknowledges that the Participant’s obligations under this Section 10 are reasonable in the context of the nature of the Company’s business, its strategic and cumulative investments in longstanding client relationships, and the competitive injuries likely to be sustained by the Company if the Participant were to violate such obligations. The Participant further acknowledges that this Agreement is made in consideration of, and is adequately supported by, the agreement of the Company to perform its obligations under this Agreement and by other consideration, which the Participant acknowledges constitutes good, valuable and sufficient consideration.

11.Miscellaneous.

a.The Company or any Subsidiary or Affiliate shall have no obligation to continue the employment relationship or any other relationship as a result of an Award under the Program and/or the Agreement. 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 RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or benefits in lieu of RSUs, even if RSUs have been granted repeatedly in the past; (iii) all decisions with respect to future RSU grants, if any, will be at the sole discretion of the Company; (iv) participation in the Program is voluntary; (v) the RSUs are not a part of normal or expected compensation or salary for any purposes; (vi) the future value of the underlying shares is unknown and cannot be predicted with certainty; and (vii) in consideration of the grant of RSUs, no claim or entitlement to compensation or damages shall arise from termination of the

RSUs or diminution in value of the RSUs 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 RSUs 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 or alter the Agreement, without the consent of the Participant so long as such amendment or alteration would not materially 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 Delaware without regard to its conflict of law principles. 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 RSUs 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:
