ARTICLE I.

AWARD OF UNITS

1.1 Award of Units. In consideration of Participant’s continued employment with the Company and for other good and valuable consideration, the Company hereby grants to Participant the number of Units set forth in the Grant Notice, subject to all of the terms and conditions set forth in this Agreement, the Grant Notice and the Plan. The Units are not an “Equity-Based Incentive” for purposes of the Amended and Restated Employment Agreement between the Company and Participant effective as of February 24, 2011 (the “Employment Agreement”).

1.2 Performance Goals and Performance Period; Certification.

(a) As of the Grant Date, each Unit has an initial value of $100.00, and represents the right to receive the Settlement Value (as defined in Sections 1.3 and 1.4 below) on the Settlement Date (as defined in Section 1.4 below) based upon the achievement of certain performance goals related to the Company’s average annual return on invested capital (the “ROIC”) and average annual revenue growth (collectively, the “Performance Goals”) for the period beginning on January 1, 2012, and ending on the Measurement Date (the “Performance Period”), which Performance Goals have been determined by the Compensation and Organizational Development Committee of the Company’s Board of Directors (the “Committee”).

(b) Except as otherwise provided in Section 1.4(b) below, the “Measurement Date” will be the first to occur of (i) December 31, 2014, or (ii) a Change in Control (as defined in Participant’s Change In Control Agreement dated May 26, 2003, as amended from time to time).

(c) Upon or following the completion of the Performance Period, the Committee shall determine, in writing, whether and to what extent the Performance Goals have been satisfied and Participant’s Settlement Value. The “Certification Date” will be the date on or following the last day of the Performance Period on which the Committee makes such determination, as follows:

(i) In the event the Measurement Date is December 31, 2014, the Certification Date shall occur prior to March 15, 2015.

(ii) In the event the Measurement Date is the date of a Change in Control, the Certification Date shall be the date of such Change in Control.

1.3 Settlement Value. Except as provided in Section 1.4 below, the “Settlement Value” of the Units will be equal to (a) $100.00, multiplied by (b) the number of Units subject to the Award, multiplied by (c) the

Performance Multiplier. The “Performance Multiplier” will be determined by the Committee on the Certification Date pursuant to the formula adopted by the Committee and set forth in an “Achievement Matrix” in the form attached hereto as Attachment 1, and will be equal to the level of achievement relative to the Performance Goals, expressed as a percentage between 0% and 200%; provided, however, that in the event the Measurement Date is the date of a Change in Control, the “Performance Multiplier” shall be the greater of (i) 100%, or (ii) actual achievement relative to the Performance Goals pursuant to the Achievement Matrix adopted by the Committee for that portion of the Performance Period beginning on January 1, 2012 and ending on the last day of the most recently completed fiscal year prior to the Change in Control. Notwithstanding the foregoing, the Committee reserves the right to reduce the actual payment in respect of the Units based on such objective and subjective criteria as deemed appropriate by the Committee; provided, however, that this provision will not apply in the event of a Change in Control.

1.4 Settlement of Units.

(a) Subject to the terms and conditions of the Plan and this Agreement, the Settlement Value of the Units shall be paid, in cash in a lump sum (less applicable taxes), on the first to occur of the following dates (the “Settlement Date”):

(i) Between January 1, 2015 and March 15, 2015; and

(ii) The date of a Change in Control (so long as such Change in Control also constitutes a change in the ownership or effective control of the Company, or a change in the ownership of a substantial portion of the assets of the Company, within the meaning of Section 409A(a)(2)(A)(v) of the Code and Section 1.409A-3(i)(5) of the Treasury Regulations) (any distribution shall occur immediately prior to the Change in Control); or

(b) Notwithstanding the foregoing, the following provisions shall apply in the event of Participant’s Separation from Service or death prior to December 31, 2014:

(i) In the event of Participant’s Involuntary Termination (as defined in Section 1.5 below), death or Separation from Service (as defined in Section 3.1(d) below) as a result of Disability (as defined in Section 1.5 below), in each case prior to December 31, 2014, (A) the Settlement Value of Participant’s Units shall be determined using a Performance Multiplier of 100%, and (B) the Settlement Value for such Units shall be paid thirty (30) days following Participant’s Separation from Service or death, as applicable (which day shall be the “Settlement Date” for purposes of the Units); and

(ii) In the event of Participant’s Qualifying Resignation (as defined in Section 1.5 below) prior to December 31, 2014, (A) the Settlement Value of Participant’s Units shall be determined using a Performance Multiplier determined based on actual achievement relative to the Performance Goals pursuant to the Achievement Matrix adopted by the Committee for that portion of the Performance Period beginning on January 1, 2012 and ending on the last day of the most recently completed fiscal year prior to the effective date of Participant’s Separation from Service (which day shall be the “Measurement Date” for purposes of the Units); and (B) the Settlement Value for such Units shall be paid thirty (30) days following Participant’s Separation from Service (which day shall be the “Settlement Date” for purposes of the Units). The Committee shall determine, in writing, whether and to what extent the Performance Goals have been satisfied for the foregoing period and Participant’s Settlement Value, within thirty (30) days following Participant’s Separation from Service.

1.5 Forfeiture; Effect of Termination.

(a) Any Units with respect to which there is no Settlement Value as a result of the Company’s failure to achieve the minimum level of achievement relative to the Performance Goals necessary in order for the Award to be payable shall automatically and without further action be cancelled and forfeited by Participant as of the Measurement Date, and Participant shall have no further right or interest in or with respect to such portion of the Units.

(b) In addition, in the event of Participant’s Separation from Service prior to the Settlement Date other than as a result of his Involuntary Termination, Qualifying Resignation (as defined below), death or Disability, then the Units shall automatically and without further action be cancelled and forfeited by Participant, and Participant shall have no further right or interest in or with respect to such portion of the Units. In the event of Participant’s Separation from Service prior to the Settlement Date as a result of his Involuntary Termination, Qualifying Resignation, death or Disability, Participant shall continue to be eligible to receive the Settlement Value of his Units, if any, on the applicable Settlement Date, as set forth in Section 1.4.

(c) The Units are further subject to cancellation (and any cash delivered in settlement of the Units is subject to repayment by Participant) if Participant engages in certain Prohibited Activities as more fully set forth in Section 2.2 of this Agreement.

(d) For purposes of this Agreement, “Disability” shall have the meaning given to such term in the Employment Agreement.

(e) For purposes of this Agreement, Participant’s “Involuntary Termination” shall mean Participant’s Separation from Service by reason of (i) his termination of employment by the Company involuntarily for a reason other than (A) Cause, (B) Executive’s becoming Disabled or (C) Participant’s death, or (ii) Participant’s resignation with Good Reason. For purposes of this Agreement, the terms “Cause” and “Good Reason” shall have the meanings given to such terms in the Employment Agreement.

(f) For purposes of this Agreement, a “Qualifying Resignation” shall mean Participant’s Separation from Service by reason of his resignation for any reason (other than Good Reason) provided that written notice for such resignation is given on or after September 1, 2013, and the effective date of such Separation from Service is at least six months following the date of such written notice.

ARTICLE III.

OTHER PROVISIONS

3.1 Section 409A.

(a) Notwithstanding any other provision of the Plan, this Agreement or the Grant Notice, the Plan, this Agreement and the Grant Notice shall be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A of the Code (together with any Treasury Regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Grant Date, “Section 409A”). The Committee may, in its discretion, adopt such amendments to the Plan, this Agreement or the Grant Notice or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, as the Committee determines are necessary or appropriate to comply with the requirements of Section 409A.

(b) The time of distribution of the Settlement Value may not be changed, except as may be permitted by the Committee in accordance with the Plan and Section 409A and the Treasury Regulations thereunder. No payment under this Agreement shall be made at a time earlier than that provided for in this Agreement unless such payment is (i) an acceleration of payment permitted to be made under Treasury Regulation §1.409A-3(j)(4) or (ii) a payment that would otherwise not be subject to additional taxes and interest under Section 409A.

(c) For purposes of Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), each payment that Participant may be eligible to receive under this Agreement shall be treated as a separate and distinct payment.

(d) Notwithstanding anything herein to the contrary, to the extent any payments to Participant pursuant to this Agreement are treated as non-qualified deferred compensation subject to Section 409A of the Code, then (i) to the extent required by Section 409A of the Code, no amount shall be payable unless Executive’s termination of employment constitutes a “separation from service” within the meaning of Section 409A (a “Separation from Service”), and (ii) if Participant, at the time of his Separation from Service, is determined by the Company to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code and the Company determines that delayed commencement of any portion of the termination benefits payable to Participant pursuant to this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code (any such delayed commencement, a “Payment Delay”), then such portion of the payments to be made to Participant shall not be provided to Participant prior to the earlier of (A) the expiration of the six-month period measured from the date of Participant’s Separation from Service, (B) the date of Executive’s death or (C) such earlier date as is permitted under Section 409A. Upon the expiration of the applicable Code Section 409A(a)(2)(B)(i) deferral period, all payments deferred pursuant to a Payment Delay shall be paid in a lump sum to Participant within thirty (30) days following such expiration, and any remaining payments due under the Agreement shall be paid as otherwise provided herein. The determination of whether Participant is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of his Separation from Service shall be made by the Company in accordance with the terms of Section 409A of the Code and applicable guidance thereunder (including without limitation Treasury Regulation Section 1.409A-1(i) and any successor provision thereto).

3.2 No Right to Continued Employment or Awards.

(a) Nothing in the Plan, the Grant Notice, or this Agreement shall confer upon Participant any right to continue in the Service of the Company or shall interfere with or restrict in any way the rights of the Company, which rights are hereby expressly reserved, to discharge or terminate the Services of Participant at any time for any reason whatsoever, except to the extent expressly provided otherwise in a written agreement between the Company and Participant.

(b) The grant of the Units is a one-time benefit and does not create any contractual or other right to receive a grant of Awards or benefits in lieu of Awards in the future. Future grants, if any, will be at the sole discretion of the Company. In addition, the value of the Units and the Settlement Value payable upon settlement thereof is an extraordinary item of compensation outside the scope of any employment contract. As such, neither the Units nor the Settlement Value payable upon settlement thereof are part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments. The future Settlement Value of the Units is unknown and cannot be predicted with certainty.

3.3 Notices. Any notice to be given under the terms of this Agreement to the Company shall be

addressed to the Company in care of the Secretary of the Company at the Company’s corporate headquarters or to the then-current email address for the Secretary of the Company, and any notice to be given to Participant shall be addressed to Participant at the most-recent physical or email address for Participant listed in the Company’s personnel records. By a notice given pursuant to this Section 3.3, either party may hereafter designate a different address for notices to be given to that party. Any notice that is required to be given to Participant shall, if Participant is then deceased, be given to the person entitled to receive the Settlement Value payable upon settlement of the Units pursuant to Section 1.1 by written notice under this Section 3.3. Any notice shall be deemed duly given (a) if delivered in person or by courier, on the date it is delivered; (b) if transmitted by email (delivery receipt requested), upon confirmation of receipt; (c) if sent by certified or registered mail (return receipt requested), on the date that mail is delivered or its delivery is first attempted; or (d) if sent by national overnight courier (with confirmation of delivery), on the next business day following deposit of such notice with such national overnight courier.

3.4 Titles. Titles are provided herein for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

3.5 Governing Law; Severability; Venue. The laws of the State of Delaware shall govern the interpretation, validity, administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws. Should any provision of this Agreement be determined by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable. The parties irrevocably agree that any and all controversies or disputes involving, relating to, or arising out of, or under, this Agreement, including but not limited to its construction, interpretation or enforcement, shall be litigated exclusively in the state or federal courts sitting in the county in which Participant primarily provides Services to the Company. Participant irrevocably and unconditionally consents to the personal jurisdiction of the state courts in the county in which Participant primarily provides Services to the Company with regard to any and all controversies or disputes involving, relating to, or arising out of, or under, this Agreement. Participant further irrevocably and unconditionally waives any defense or objection of lack of personal jurisdiction over Participant by the state or federal courts sitting in the county in which Participant primarily provides Services to the Company.

3.6 Conformity to Applicable Laws. Participant acknowledges that the Plan, the Grant Notice and this Agreement are intended to conform, and shall be deemed amended, to the extent necessary, with all provisions of applicable law. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Units are granted and may be settled, only in such a manner as to conform to applicable law.

3.7 Tax Representations. Participant has reviewed with Participant’s own tax advisors the federal, state, local and foreign tax consequences of this investment and the transactions contemplated by the Grant Notice and this Agreement. Participant is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

3.8 Successors and Assigns. The Company may assign any of its rights under this Agreement to single or multiple assignees and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions herein set forth in Article II, this Agreement shall be binding upon Participant and his or her heirs, executors, administrators, successors and assigns.

3.9 Paperless Administration. By accepting this Award, Participant hereby agrees to receive documentation related to the Award by electronic delivery, such as a system using an internet website or interactive voice response, maintained by the Company or a third party designated by the Company.

3.10 Amendment, Suspension and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the Committee; provided that, except as may otherwise be provided by the Plan, no amendment, modification, suspension or termination of this Agreement shall impair any rights or obligations under this Agreement in any material way without the prior written consent of Participant.

3.11 Entire Agreement. The Plan, the Grant Notice and this Agreement constitute the entire agreement of the parties and supersede in their entirety all oral, implied or written promises, statements, understandings, undertakings and agreements between the Company and Participant with respect to the subject matter hereof, including without limitation, the provisions of any employment agreement or offer letter regarding incentive awards to be awarded to Participant by the Company, or any other oral, implied or written promises, statements, understandings, undertakings or agreements by the Company or any of its representatives regarding equity awards to be awarded to Participant by the Company.

3.12 Unsecured Obligation. Prior to the Settlement Date, the Units represent an unsecured obligation of the Company, payable only from the general assets of the Company.

3.13 Tax Withholding. The amounts payable to Participant on the Settlement Date shall be subject to all federal, state, local and foreign tax withholding applicable with respect to the taxable income of Participant resulting from the settlement of the Units.
