Performance-Based Restricted Stock Award Agreement

Award. Pursuant to the Plan and the LTIP, the Company hereby awards to the Grantee the Target Award of Restricted Stock. The number of Shares that the Grantee will vest in will be determined based on the conditions and Performance Measures contained in Paragraph 2. Subject to the restrictions set forth in the Plan, the Grantee will have the rights and privileges of a stockholder as to the Restricted Stock, including without limitation the right to vote such Restricted Stock.

Vesting and Expiration of Restricted Period.

For purposes of this Agreement, the “Performance Period” shall be the three-year period beginning on January 1, 2018 and ending on December 31, 2020.

The Restricted Stock is subject to forfeiture until it vests. Except as otherwise provided herein or in the Plan, the Restricted Stock will vest and the Restricted Period will expire on the last day of the Performance Period, subject to the Grantee’s continuous service to the Company from the Grant Date through the last day of the Performance Period.

The percentage of Restricted Stock that will actually vest will range from 0% to 200% and be based, in equal parts, on the achievement of the following Performance Measures:

Total shareholder return over the Performance Period as compared to the Company’s Peer Group, as determined pursuant to Exhibit A attached hereto; and

Free Cash Flow as Percentage of Revenue, as determined pursuant to Exhibit B attached hereto.

Following the end of the Performance Period, the Committee will determine in its sole discretion and certify in writing whether, and to what extent, the Performance Measures were achieved for the Performance Period (“Actual Performance”). Based on Actual Performance, the Committee will then calculate and certify in writing the percentage of the Restricted Stock that the Grantee will vest in (the “Actual Award”). Any Restricted Stock outstanding and unvested at the end of the Performance Period will be forfeited. The determination of Actual Performance will be in the sole discretion of the Committee and will be final, conclusive, binding and unappealable.

Except as otherwise provided herein, upon vesting, the restrictions set forth in the Plan or in this Award Agreement will be of no further force or effect with respect to vested Restricted Stock.

Delivery. The Shares underlying the Restricted Stock will be held by the Company in the Grantee’s name and will be delivered promptly following the date on which the Restricted Stock vests.

Dividends. No dividends payable on the Restricted Stock will be paid or accumulated by the Company until such Restricted Stock vests and the restrictions on such Restricted Stock expire.

Forfeiture. Except as provided in Paragraph 6 or 7 and Sections 13.1 and 15.7 of the Plan, or as otherwise determined by the Committee, upon the Grantee’s Termination prior to vesting and the expiration of the Restricted Period, any outstanding, unvested Restricted Stock will be forfeited.

Death or Disability. Notwithstanding any other provision of this Award Agreement or the Plan, upon the Grantee’s Termination due to death or Disability prior to vesting and the expiration of the Restricted Period, the Grantee will vest in a prorated portion of his or her Target Award, prorated based on the number of days continuously employed during the Performance Period, and the Shares underlying the Restricted Stock will be delivered promptly following the Grantee’s Termination.

Retirement. Notwithstanding any other provision of this Award Agreement or the Plan, upon the Grantee’s Termination due to Retirement prior to vesting and the expiration of the Restricted Period, the Grantee will vest in a prorated portion of his

Clawback Policy/Recoupment. The Award of Restricted Stock is subject to the clawback provisions of Section 15.20 of the Plan, any applicable law and any Company policy on the recovery of compensation, as it exists now or as later adopted and as amended and in effect from time to time.

Transferability and Resale Restrictions. Prior to vesting and the expiration of the Restricted Period, the Restricted Stock may not be assigned, alienated, pledged, attached, sold, or otherwise transferred or encumbered by the Grantee other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer, or encumbrance will be void and unenforceable against the Company or any Affiliate. Any Shares delivered pursuant to this Award Agreement will be subject to such conditions and restrictions on transfer (if any) as are set forth in the Company’s certificate of incorporation and bylaws, as well as any stockholders agreement and any other agreement entered into with respect to such Shares.

Tax Representations and Tax Withholding. The Grantee has had an opportunity to review with his or her own tax advisors the federal, state, local and foreign tax consequences of the transactions contemplated by this Award Agreement. The Grantee is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. The Grantee will be required to pay to the Company or any Affiliate, and the Company or any Affiliate will have the right to withhold, from any cash or shares deliverable under this Award or from any compensation or other amounts owing to the Grantee, the amount of any required withholding taxes in respect of this Award, its exercise, or any payment or transfer under this Award and to take such other action as may be necessary in the opinion of the Committee or the Company to satisfy all obligations for the payment of such withholding and taxes.

83(b) Elections. The grant of Restricted Stock in this Award Agreement is intended to constitute a transfer of such Restricted Stock within the meaning of Code Section 83. Accordingly, the Grantee is eligible to make an election under Code Section 83(b) with respect to the Restricted Stock, subject to complying with all applicable requirements for making such an election, including, but not limited to, the requirement that such election be made within 30 days after the Grant Date. If the Grantee makes an election under Code Section 83(b), the Grantee will notify the Company of such election within 10 days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to Code Section 83(b) or other applicable provision.
