1. Definitions.  All capitalized terms not defined in this Agreement that are defined in the Employment Agreement will have the meanings ascribed to them in the Employment Agreement.  The following terms, when used in this Agreement, have the following meanings:

2. Grant of Restricted Stock Units.  Subject to the terms and conditions herein and in the Plan, the Company hereby awards to the Grantee as of the Grant Date, an Award of 29,438 restricted stock units (the “Restricted Stock Units”), each representing the right to receive one share of the Company’s Common Stock, subject to the conditions and restrictions set forth below in this Agreement and in the Plan.  Regarding the last sentence of Section 8.5 of the Plan, the Company acknowledges and agrees that there are no restrictions, terms or conditions that will cause a forfeiture of the Restricted Stock Units or any Dividend Equivalents with respect thereto that are not set forth in this Agreement.

3. Conditions of Vesting.  Unless otherwise determined by the Committee in its sole discretion (provided that such determination is not adverse to the Grantee), the Restricted Stock Units will vest only in accordance with the conditions stated in this Section 3.  Upon vesting, Restricted Stock Units and the related Dividend Equivalents shall not be subject to forfeiture other than as provided in Section 9 hereof. 

(a) After December 31, 2017 but on or prior to March 15, 2018, the Committee will certify that portion, if any, of the 162(m) Objectives that has been achieved (the “Achieved 162(m) Objectives”), the date as of which such certification is made being referred to as the “Committee Certification Date.”  The Committee may apply Negative Discretion Criteria in accordance with the 2017 Performance Equity Program to reduce the number of Restricted Stock Units that would otherwise vest based solely on the Achieved 162(m) Objectives; provided, that to the extent the Negative Discretion Criteria include objective performance criteria in relation to the performance or value of the Company, its Subsidiaries, its affiliates and/or any division or business unit of any of the foregoing, the Committee will not exercise negative discretion with respect to vesting that number, if any, of the Restricted Stock Units that relate solely to such objective performance criteria.

(b) The Committee will promptly notify the Grantee regarding the number of Restricted Stock Units, if any, that have vested pursuant to Section 3(a) as of the Committee Certification Date (with any fractional Restricted Stock Unit rounded up to the nearest whole Restricted Stock Unit). 

(c) Any Dividend Equivalents with respect to the Restricted Stock Units that have not theretofore become Vested Dividend Equivalents (“Unpaid Dividend Equivalents”) will become vested and payable to the extent that the Restricted Stock Units related thereto shall have become vested in accordance with this Agreement.  Notwithstanding the foregoing, but subject to Section 7, the Grantee will not vest, pursuant to this Section 3, in Restricted Stock Units or related Unpaid Dividend Equivalents in which the Grantee would otherwise vest as of a given date if the Grantee has not been continuously employed by the Company from the Grant Date through such date (the vesting or forfeiture of such Restricted Stock Units and related Unpaid Dividend Equivalents to be governed instead by Section 7). 

4. Settlement of Restricted Stock Units.  Settlement of Restricted Stock Units (and related Unpaid Dividend Equivalents) that vest in accordance with Section 3 shall be made as soon as administratively practicable after the applicable Vesting Date, but in no event later than March 15, 2018.  Settlement of vested Restricted Stock Units shall be made in payment of shares of Common Stock, together with any related Dividend Equivalents, in accordance with Section 6.  Any shares of Common Stock so received shall be fully vested.

5. Mandatory Withholding for Taxes.  To the extent that the Company is subject to withholding tax requirements under any national, state, local or other governmental law with respect to the award of the Restricted Stock Units to the Grantee or the vesting or settlement thereof, or the designation of any Dividend Equivalents as payable or distributable or the payment or distribution thereof, the Grantee must make arrangement satisfactory to the Company to make payment to the Company or its designee of the amount required to be withheld under such tax laws, as determined by the Company (collectively, the “Required Withholding Amount”).  To the extent such withholding is required, the Company shall withhold (a) from the shares of Common Stock represented by such vested Restricted Stock Units and otherwise deliverable to the Grantee a number of shares of Common Stock and/or (b) from any related Dividend Equivalents otherwise deliverable to the Grantee an amount of such Dividend Equivalents, which collectively have a value (or, in the case of securities withheld, a Fair Market Value) as of the date the obligation to

withhold arises equal to the Required Withholding Amount, unless the Grantee remits the Required Withholding Amount to the Company or its designee in cash in such form and by such time as the Company may require or other provisions for withholding such amount satisfactory to the Company have been made.  Notwithstanding any other provisions of this Agreement, the delivery of any shares of Common Stock represented by vested Restricted Stock Units and any related Dividend Equivalents may be postponed until any required withholding taxes have been paid to the Company.  Notwithstanding the foregoing or anything contained herein to the contrary, (i) the Grantee may, in his sole discretion, direct the Company to deduct from the shares of Common Stock represented by vested Restricted Stock Units and otherwise deliverable to the Grantee a number of shares of Common Stock having a Fair Market Value on the date the obligation to withhold arises equal to the Required Withholding Amount and (ii) the Company will not withhold any shares of Common Stock to pay the Required Withholding Amount if the Grantee has remitted cash to the Company or a Subsidiary or designee thereof in an amount equal to the Required Withholding Amount by such time as the Company may require.

6. Delivery by the Company.  As soon as practicable after the vesting of Restricted Stock Units, and any related Unpaid Dividend Equivalents, pursuant to Section 3 (but in no event later than March 15, 2018), and subject to the withholding referred to in Section 5, the Company will (a) register in a book entry account in the name of the Grantee, or cause to be issued and delivered to the Grantee (in certificate or electronic form), that number of shares of Common Stock represented by such vested Restricted Stock Units and any securities representing related vested Unpaid Dividend Equivalents, and (b) cause to be delivered to the Grantee any cash payment representing related vested Unpaid Dividend Equivalents.  Any delivery of securities will be deemed effected for all purposes when a certificate representing, or statement of holdings reflecting, such securities and, in the case of any Unpaid Dividend Equivalents, any other documents necessary to reflect ownership thereof by the Grantee, have been delivered personally to the Grantee or, if delivery is by mail, when the Grantee has received such certificates or other documents.  Any cash payment will be deemed effected when a check from the Company, payable to the Grantee and in the amount equal to the amount of the cash owed, has been delivered personally to the Grantee or, if delivery is by mail, upon receipt by the Grantee.

7. Termination of Restricted Stock Units.  The Restricted Stock Units will be forfeited and terminate at the time specified below: 

(a) Any Restricted Stock Units that do not become vested in accordance with Section 3 of this Agreement as of the Committee Certification Date, and any related Unpaid Dividend Equivalents, will automatically be forfeited as of the Close of Business on the Committee Certification Date.

(b) Unless otherwise determined by the Committee in its sole discretion, if the Grantee’s Separation occurs for any reason prior to the Close of Business on December 31, 2017, including as a result of death, Disability, termination by the Company for Cause, termination by the Company without Cause or termination by the Grantee with or without Good Reason, the Restricted Stock Units, to the extent not theretofore vested, and any related Unpaid Dividend Equivalents, will be forfeited immediately; provided, that if the Grantee remains employed until the Close of Business on December 31, 2017 and the Grantee’s Separation then occurs on or prior to the Committee Certification Date, the

Restricted Stock Units and the related Unpaid Dividend Equivalents will remain outstanding until the Committee Certification Date and will vest under Section 3 on such date to the extent the Committee certifies they have vested in accordance with Section 3.  Upon forfeiture of any unvested Restricted Stock Units, and any related Unpaid Dividend Equivalents, such Restricted Stock Units and any related Unpaid Dividend Equivalents will be immediately cancelled, and the Grantee will cease to have any rights with respect thereto.

8. Nontransferability of Restricted Stock Units.  Restricted Stock Units and any related Unpaid Dividend Equivalents, are not transferable (either voluntarily or involuntarily) before or after the Grantee’s death, except as follows:  (a) during the Grantee’s lifetime, pursuant to a domestic relations order issued by a court of competent jurisdiction that is not contrary to the terms and conditions of the Plan or this Agreement, and in a form acceptable to the Committee; or (b) after the Grantee’s death, by will or pursuant to the applicable laws of descent and distribution, as may be the case.  Any person to whom Restricted Stock Units are transferred in accordance with the provisions of the preceding sentence shall take such Restricted Stock Units subject to all of the terms and conditions of the Plan and this Agreement, including that the vesting and termination provisions of this Agreement will continue to be applied with respect to the Grantee.  Certificates representing Restricted Stock Units that have vested may be delivered (or, in the case of book entry registration, registered) only to the Grantee (or during the Grantee’s lifetime, to the Grantee’s court appointed legal representative) or to a person to whom the Restricted Stock Units have been transferred in accordance with this Section.

9. Forfeiture for Misconduct and Repayment of Certain Amounts.  If (i) a material restatement of any financial statement of the Company (including any consolidated financial statement of the Company and its consolidated subsidiaries) is required and (ii) in the reasonable judgment of the Committee, (A) such restatement is due to material noncompliance with any financial reporting requirement under applicable securities laws and (B) such noncompliance is a result of misconduct on the part of the Grantee, the Grantee will repay to the Company Forfeitable Benefits received by the Grantee during the Misstatement Period in such amount as the Committee may reasonably determine, taking into account, in addition to any other factors deemed relevant by the Committee, the extent to which the market value of Common Stock during the Misstatement Period was affected by the error(s) giving rise to the need for such restatement.  “Forfeitable Benefits” means (i) any and all cash and/or shares of Common Stock received by the Grantee (A) upon the exercise during the Misstatement Period of any SARs held by the Grantee or (B) upon the payment during the Misstatement Period of any Cash Award or Performance Award held by the Grantee, the value of which is determined in whole or in part with reference to the value of Common Stock, and (ii) any proceeds received by the Grantee from the sale, exchange, transfer or other disposition during the Misstatement Period of any shares of Common Stock received by the Grantee upon the exercise, vesting or payment during the Misstatement Period of any Award held by the Grantee.  By way of clarification, “Forfeitable Benefits” will not include any shares of Common Stock delivered in respect of the vesting of any Restricted Stock Units during the Misstatement Period or any securities received as Dividend Equivalents in respect thereof, in each case that are not sold, exchanged, transferred or otherwise disposed of during the Misstatement Period.  “Misstatement Period” means the 12-month period beginning on the date of the first public issuance or the filing with the Securities and Exchange Commission, whichever occurs earlier, of the financial statement requiring restatement.

10. No Stockholder Rights; Dividend Equivalents.  The Grantee will not be deemed for any purpose to be, or to have any of the rights of, a stockholder of the Company with respect to any shares of Common Stock represented by any Restricted Stock Units unless and until such time as shares of Common Stock represented by vested Restricted Stock Units have been delivered to the Grantee in accordance with Section 6, nor will the existence of this Agreement affect in any way the right or power of the Company or any  stockholder of the Company to accomplish any corporate act, including, without limitation, any reclassification, reorganization or other change of or to its capital or business structure, merger, consolidation, liquidation or sale or other disposition of all or any part of its business or assets.  The Grantee will have no right to receive, or otherwise with respect to, any Dividend Equivalents until such time, if ever, as (a) the Restricted Stock Units with respect to which such Dividend Equivalents relate shall have become vested, or (b) such Dividend Equivalents shall have become vested in accordance with the third to last sentence of this Section, and, if vesting does not occur, the related Dividend Equivalents will be forfeited.  Dividend Equivalents shall not bear interest or be segregated in a separate account.  Notwithstanding the foregoing, the Committee may, in its sole discretion, accelerate the vesting of any portion of the Dividend Equivalents (the “Vested Dividend Equivalents”).  The settlement of any Vested Dividend Equivalents shall be made as soon as administratively practicable after the accelerated vesting date, but in no event later than March 15, 2017.  With respect to any Restricted Stock Units and Dividend Equivalents, the Grantee is a general unsecured creditor of the Company.

11. Adjustments.  If the outstanding shares of Common Stock are subdivided into a greater number of shares (by stock dividend, stock split, reclassification or otherwise) or are combined into a smaller number of shares (by reverse stock split, reclassification or otherwise), or if the Committee determines that any stock dividend, extraordinary cash dividend, reclassification, recapitalization, reorganization, split-up, spin-off, combination, exchange of shares, warrants or rights offering to purchase any shares of Common Stock or other similar corporate event (including mergers or consolidations) affects shares of Common Stock such that an adjustment is required to preserve the benefits or potential benefits intended to be made available under this Agreement, then the Restricted Stock Units will be subject to adjustment in such manner as the Committee, in its sole discretion, deems equitable and appropriate in connection with the occurrence of any of the events described in this Section 11 following the Grant Date.

12. Restrictions Imposed by Law.  Without limiting the generality of Section 10.8 of the Plan, the Company will not be obligated to deliver any shares of Common Stock represented by vested Restricted Stock Units or securities constituting any Unpaid Dividend Equivalents if counsel to the Company determines that the issuance or delivery thereof would violate any applicable law or any rule or regulation of any governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which shares of Common Stock or such other securities are listed or quoted.  The Company will in no event be obligated to take any affirmative action in order to cause the delivery of shares of Common Stock represented by vested Restricted Stock Units or securities constituting or cash payment related to any Unpaid Dividend Equivalents to comply with any such law, rule, regulation, or agreement.

13. Notice.  Unless the Company notifies the Grantee in writing of a different procedure or address, any notice or other communication to the Company with respect to this

Agreement will be in writing and will be delivered personally or sent by United States first class mail, postage prepaid and addressed as follows:

(b) subject to any required action by the Board or the stockholders of the Company, the Restricted Stock Units granted under this Agreement may be canceled by the Company and a new Award made in substitution therefor, provided, that the Award so substituted will satisfy all of the requirements of the Plan as of the date such new Award is made and no such action will adversely affect any Restricted Stock Units (after taking into account any related Unpaid Dividend Equivalents).

15. Grantee Employment.  Nothing contained in this Agreement, and no action of the Company or the Committee with respect hereto, will confer or be construed to confer on the Grantee any right to continue in the employ of the Company or interfere in any way with the right of the Company to terminate the Grantee’s employment at any time, with or without Cause, subject to the provisions of the Employment Agreement.

16. Nonalienation of Benefits.  Except as provided in Section 8, (a) no right or benefit under this Agreement will be subject to anticipation, alienation, sale, assignment, hypothecation, pledge, exchange, transfer, encumbrance or charge, and any attempt to anticipate, alienate, sell,

assign, hypothecate, pledge, exchange, transfer, encumber or charge the same will be void, and (b) no right or benefit hereunder will in any manner be liable for or subject to the debts, contracts, liabilities or torts of the Grantee or other person entitled to such benefits.
