2.1. Additional Conditions. Subject to the terms and conditions set forth herein and in the Plan and unless the Committee determines otherwise, in its sole discretion, a Participant’s right, if any, to receive payment of their respective Financial Performance Awards shall also be contingent upon satisfaction of each of the following requirements:

a. A Participant must execute a Confidentiality, Intellectual Property and Non-Compete Agreement in a form satisfactory to the Committee and deliver the executed agreement to the Company’s Vice President, Human Resources and Administration on or before October 1 of the applicable Fiscal Year. If a Participant previously has executed a Confidentiality, Intellectual Property and Non-Compete Agreement, the Participant need not execute and deliver another Confidentiality, Intellectual Property and Non-Compete Agreement.

b. A Participant’s Target Percentage award shall be specifically established by the Committee as set forth in Section 3.1. In the event a Participant changes from one position to another position or is promoted into one of the positions approved by the Committee as described in Section 3.1 during the Fiscal Year performance period, the Target Percentage for such Participant shall be pro-rated between the Target Percentages of each position held during the Fiscal Year based on which position was held on the first day of each month in the Fiscal Year performance period and may be allocated among different Operating Units as determined by the Committee. Any newly hired Participant shall have a specific Target Percentage established by the Committee, provided their employment began in such position by October 1 of the Fiscal Year performance period.

c. Except as otherwise expressly set forth in Section 6 of the Plan or as otherwise determined by the Committee, if a Participant’s employment terminates with the Company prior to the Payment Date, the Participant shall forfeit any and all rights to payment or any Financial Performance Award granted hereunder.

d. For Participants who are Section 162(m) Officers, funding of the Section 162(m) Officer Bonus Pool.

The Section 162(m) Officer Bonus Pool shall be funded and allocable to Participants who are Section 162(m) Officers in the percentages set forth on an exhibit on file with the Committee, subject to the Committee’s right to reduce any such allocations in its sole discretion. In this regard, the Target Percentage and Target Amount, as described in Sections 3.1 and 3.2 below, will be considered by the Committee in exercising its right of discretion.

3.1. Target Percentages. Each Participant shall have a Target Percentage based upon the position held by such Participant as approved by the Committee on January 25, 2016 and set forth on an exhibit on file with the Committee.

Other employees selected by the Committee may also be made Participants in the Plan on such terms as may be approved by the Committee and consistent with the terms of the Plan.

3.2. Target Amount. The target amount of a Participant’s Financial Performance Award, if any, shall be determined and allocated based on the percentages specified in the table below:

3.3. Financial Performance Award Multiplier. Subject to the terms and conditions set forth herein and in the Plan, the amount of Financial Performance Award earned shall be calculated and adjusted upward or downward based on the actual level of attainment of Target W/C as a % of Sales (Corporate and Operating Unit), Target Adjusted EBITDA (Corporate and Operating Unit) and/or Target ROIC (as allocated under Section 3.2) utilizing the percentage multiplier as set forth in the following tables:

a. Adjusted EBITDA Multiplier (Corporate/Operating Unit)

b. ROIC Multiplier

c. W/C as a % of Sales Multiplier

The calculation of the percent of target achieved in the above tables shall be adjusted proportionately to reflect whole percentages achieved between the levels in the table. For example, if Corporate achieved 73% of Target Adjusted EBITDA, the percent of target achieved would be 57%; if Corporate achieved 137% of Target Adjusted EBITDA, the percent of target achieved would be 156%.

3.4. Limitation on Financial Performance Award. Notwithstanding any provision to the contrary, a Participant’s Financial Performance Award shall not exceed (i) $1,500,000 for any Participant for the Fiscal Year performance period under the Plan (and after including any other awards granted under the Plan for the Fiscal Year) or (ii) if lower, for any Participant who is a Section 162(m) Officer, such Participant’s designated performance pool percentage of the Section 162(m) Officer Bonus Pool as set forth on an exhibit on file with the Committee. In the event that the amount of any award(s) for the Fiscal Year earned exceed $1,500,000, in the aggregate, for a Participant, or the designated performance pool percentage for any Section 162(m) Officer, such award(s) shall be reduced to $1,500,000 or, if lower, the applicable designated performance pool percentage. The decision as to how and, if applicable, which award(s) shall be reduced shall be made in a manner determined in the sole discretion of the Committee.

In the event the Company is required to prepare an accounting restatement applicable to any financial reporting period covering a period within the Fiscal Year due to the material noncompliance of the Company with any financial reporting requirement under the securities laws or other applicable law and if the Committee, in its discretion, so determines, each “Specified Participant” (as defined below) shall pay to the Company, in cash, all cash paid to or on behalf of such Participant under the Plan for the Fiscal Year in excess of the amount of such compensation that would have been paid to the Participant for the Fiscal Year based on the restated financial results. Any such payment shall be made within the time periods prescribed by the Committee. The term “Specified Participant” means any Participant that the Committee has determined, in its sole discretion, has committed fraud, negligence, or intentional misconduct that was a significant contributing factor to the Company having to prepare an accounting restatement. A Specified Participant’s failure to make any such timely payment to the Company constitutes an independent and material breach of the terms and conditions of the Plan, for which the Company may seek recovery of the unpaid amount as liquidated damages, in addition to all other rights and remedies the Company may have against the Participant. By participating in the Plan, each Participant agrees that timely payment to the Company as set forth in this Section IV is (i) reasonable and necessary, (ii) is not a penalty, and (iii) does not preclude the Company from seeking all other remedies that may be available to the Company.

The Committee, in its discretion, shall determine whether the Company shall effect any such recovery (i) by seeking repayment from the Specified Participant, (ii) by reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement) the amount that would otherwise be payable to the Specified Participant under any compensatory plan, program or arrangement maintained by the Company or any of its affiliates, (iii) by withholding payment of future increases in compensation (including the payment of any discretionary bonus amount) or grants of compensatory awards that would otherwise have been made in accordance with the Company’s otherwise applicable compensation practices, or (iv) by any combination of the foregoing.

Notwithstanding any other provisions of this document, any awards made hereunder shall be subject to recovery under any law, governmental regulation, stock exchange listing requirement or Company policy applicable to them, including any related deductions, recoupment and/or claw-back as may be required to be made pursuant to such law, government regulation, stock exchange listing requirement, or Company policy, as may be in effect from time to time, and which may operate to create additional rights for the Company with respect to the awards and recovery of amounts relating thereto (the “Clawback Requirement”). By accepting Financial Performance Awards granted hereunder and under the Plan, Participants agree and acknowledge that they are obligated to cooperate with, and provide any and all assistance necessary

to, the Company to recover or recoup any award or amounts paid under the Plan subject to claw-back pursuant to such law, government regulation, stock exchange listing requirement or Company policy. Such cooperation and assistance shall include, but is not limited to, executing, completing and submitting any documentation necessary to recover or recoup any award or amounts paid under the Plan from a Participant’s accounts, or pending or future compensation or awards. In the event the awards granted pursuant to this document and the Plan become subject to such Clawback Requirement, then the awards shall be subject to such Clawback Requirement, and the foregoing provision of this Section IV shall no longer apply to such awards.

Notwithstanding the foregoing, the Company shall not be required to make any additional payment in the event that the restated financial results would have resulted in a greater payment to any Participant.

All determinations with respect to any Financial Performance Award shall be made by the Committee and shall be final, conclusive and binding on the Company, the Participant and any and all interested parties. No payment of a Financial Performance Award shall be made prior to the Committee certifying in writing that the performance goals and other material terms applicable to such awards for the Fiscal Year as set forth herein (including the Schedule attached hereto and/or the applicable exhibits on file with the Committee) have been attained.

The undersigned Chairman of the Committee hereby certifies, on behalf of the Committee, that the performance goals and other material terms applicable to the awards for the Fiscal Year as set forth herein (including the Schedule attached hereto) have been determined and approved at the Committee meeting on January 25, 2016.
