(the “Company”), pursuant to the 2018 Omnibus Award Plan, as amended from time to time (the “Plan”), hereby irrevocably grants you (the “Participant”), on [DATE] (the “Grant Date”), (x) if the Participant’s home country is the United States, a Restricted Stock Award (the “Restricted Stock Award”) of forfeitable shares of the Company’s Common Stock, par value $0.10 per share (“Restricted Stock”) or (y) if the Participant’s home country is not the United States, a forfeitable Restricted Stock Unit Award (the “Restricted Unit Award”), in each case, subject to (1) the restrictions, terms and conditions herein, and (2) any additional terms and conditions applicable to the Participant, as set forth in the appendices attached hereto (the “Appendices”).

WHEREAS, the Compensation Committee (the “Committee”) of the Board of Directors of the Company (the “Board”) has determined that it would be in the best interests of the Company and its stockholders to grant the award provided for herein to the Participant, on the terms and conditions described in this Restricted Stock and Restricted Stock Unit Award Agreement, including the Appendices, together, the “Agreement”).

NOW, THEREFORE, for and in consideration of the promises and the covenants of the parties contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto, for themselves, and their permitted successors and assigns, hereby agree as follows:

1.Terms and Conditions.

(a)Vesting. Subject to the other terms and conditions contained in this Agreement, the Restricted Period with respect to:

(i)one third of the shares of Restricted Stock or the Restricted Unit Award, as applicable, shall lapse on the first anniversary of the Grant Date;

(ii)an additional one third of the shares of Restricted Stock or the Restricted Unit Award, as applicable, shall lapse on the second anniversary of the Grant Date; and

(iii)the remainder of the shares of Restricted Stock or the Restricted Unit Award, as applicable, shall lapse on the third anniversary of the Grant Date;

in each case, subject to any additional terms and conditions applicable to the Participant, as set forth in the Appendices. Notwithstanding the foregoing, the Restricted Period with respect to any unvested shares of Restricted Stock or any unvested portion of the Restricted Unit Award, as applicable, shall lapse as of immediately prior to the consummation of a Change in Control, unless the successor company, or a parent of the successor company, in the Change in Control agrees to assume, replace, or substitute the unvested shares of Restricted Stock or the unvested portion of the Restricted Unit Award, as applicable, granted hereunder (as of the consummation

of such Change in Control) with shares of restricted stock or restricted units, as applicable, on substantially identical terms, as determined by the Committee.

(b)Book Entry; Payment.

(i)Book Entry. If the Participant’s home country is the United States, upon the grant of Restricted Stock, the Committee shall cause share(s) of Common Stock to be registered in the name of the Participant and held in book-entry form subject to the Company’s directions.

(ii)Payment. If the Participant’s home country is not the United States, (x) the Company shall settle as soon as administratively possible after the applicable vesting date, any vested portion of the Restricted Unit Award by the payment to the Participant in cash (without interest) of an amount equal to the Participant’s vested portion of the Restricted Unit Award, subject to applicable Tax-Related Items (as defined in Appendix B to this Restricted Stock and Restricted Stock Unit Award Agreement) and (y) at no time shall the Participant be deemed for any purpose to be the owner of shares of Common Stock in connection with a Restricted Unit Award and the Participant shall have no right to dividends or dividend equivalent payments in respect of the Restricted Unit Award.

(c)Forfeiture. Except as otherwise determined by the Committee in its sole discretion or as set forth in Section 1(a), unvested shares of Restricted Stock or any unvested portion of Restricted Unit Awards, as applicable, shall be forfeited without consideration to the Participant upon the Participant’s termination of employment with the Company or its Affiliates for any reason. For the avoidance of doubt, unless otherwise provided in this Agreement, employment or service during only a portion of the vesting period until the respective vesting date shall not entitle the Participant to vest in a pro-rata portion of the Restricted Stock or Restricted Unit Award scheduled to vest on such date.

Further, if the Participant’s home country is not the United States, for purposes of the Award, the Participant’s employment relationship will be considered terminated as of the date the Participant is no longer actively providing services to the Company or one of its Affiliates (regardless of the reason for such termination and whether or not such termination is later found invalid or in breach of employment laws in the jurisdiction where the Participant is employed, or the terms of the Participant’s employment agreement, if any), and such date will not be extended by any notice period (e.g., the Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s employment agreement, if any). The Committee shall have the exclusive discretion to determine when the Participant may still be considered to be providing active services for purposes of the Award (including whether the Participant may still be considered to be providing services while on a leave of absence).

2.Restrictive Covenant Agreement; Clawback; Incorporation by Reference.

(a)Restrictive Covenant Agreement. If the Participant’s home country is Australia, Canada, or the United States, this Restricted Stock Award or Restricted Unit Award, as applicable, is conditioned upon the Participant’s agreement to this Agreement and the Restrictive Covenant Agreement furnished herewith and which includes, among other provisions, certain non-competition, non-solicitation and non-disclosure covenants. If such Participant does not agree (whether electronically or otherwise) to this Agreement and the Restrictive Covenant Agreement within ninety (90) days from the date of the Restricted Stock Award or Restricted Unit Award, as applicable, the Restricted Stock Award or Restricted Unit Award, as applicable, shall be terminable by the Company.

(b)Clawback/Forfeiture. Notwithstanding anything to the contrary contained herein, the Restricted Stock or the Restricted Unit Award, as applicable, may be forfeited without consideration if the Participant, as determined by the Committee in its sole discretion (i) engages in an activity that is in conflict with or adverse to the interests of the Company or any Affiliate, including but not limited to fraud or conduct contributing to any financial restatements or irregularities, or (ii) without the consent of the Company, while employed by or providing services to the Company or any Affiliate or after termination of such employment or service, violates a non-competition, non-solicitation or non-disclosure covenant or agreement (including, if applicable, the Restrictive Covenant Agreement furnished herewith) between the Participant and the Company or any Affiliate. If the Participant engages in any activity referred to in the preceding sentence, the Participant shall, at the sole discretion of the Committee, (x) if the Participant’s home country is the United States, forfeit any gain realized in respect of the Restricted Stock (which gain shall be deemed to be an amount equal to the Fair Market Value, on the applicable vesting date, of the shares of Common Stock delivered to the Participant), and repay such gain to the Company or (y) if the Participant’s home country is not the United States, forfeit the amount paid in respect of the Restricted Unit Award, and repay such amount to the Company.
