This Agreement is not enforceable until you accept the Agreement electronically.

1.Incorporation by Reference; Plan Document Receipt. This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments to the Plan adopted at any time and from time to time unless such amendments are expressly intended not to apply to this Agreement), and the terms and provisions of the Plan are made part of and incorporated into this Agreement as if they were set forth in this Agreement. Any capitalized term not defined in this Agreement shall have the meaning given in the Plan. The Participant acknowledges receipt of a copy of the Plan and that the Participant has read the Plan carefully and fully understands it. If there is any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control.

2.Grant of Restricted Stock Unit Award. The Company grants to the Participant, as of the Grant Date, the number of RSUs specified above. Except as otherwise provided by the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection against potential future dilution of the Participant’s interest in the Company for any reason. No adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of the shares of Common Stock underlying the RSUs, except as otherwise specifically provided for in the Plan or this Agreement.

(a)Subject to Sections 3(b) and 3(c), (i) 100% of the RSUs granted under this Agreement shall vest on March 1, 2025, as long as the Participant has not incurred a Termination prior to that date, and (ii) if the Participant incurs a Termination prior to March 1, 2025, a pro rata portion of the RSUs granted under this Agreement shall vest on the date of Termination. The pro rata portion shall be calculated based on a fraction, the numerator of which is the number of days elapsed from the Grant Date to the date of the Participant’s Termination and the denominator of which is 365. There shall be no proportionate or partial vesting prior to the vesting date, except as provided in this Section.

(d)Forfeiture. Subject to the Committee’s discretion to accelerate vesting pursuant to Section 3(b), all unvested RSUs shall be immediately forfeited upon the Participant’s Termination for any reason, except as provided in Section 3(a).

(b)Time of Payment. The designated payment date shall be the applicable vesting date in Section 3(a) for RSUs vesting pursuant to Section 3(a); the vesting date specified by the Committee for RSUs vesting pursuant to Section 3(b); or the date of Change in Control for RSUs vesting

(c)Blackout Periods. If the Participant is subject to any Company “blackout” policy or other trading restriction imposed by the Company on the date distribution would otherwise be made pursuant to Section 4(a), distribution shall be instead made on the earlier of (i) the date that the Participant is not subject to any such policy or restriction and (ii) the later of (A) December 31 of the calendar year in which distribution would otherwise have been made and (B) the date that is immediately prior to the expiration of two and one-half months following the date distribution would otherwise have been made.

(d)Short-Term Deferral. This Award is intended to satisfy the “short-term deferral” rules of Section 409A of the Internal Revenue Code and the regulations thereunder and therefore is not subject to Section 409A of the Internal Revenue Code. If it is determined that this Award is not a short-term deferral, the administration of this Award shall comply with Section 409A of the Internal Revenue Code and the regulations thereunder.

5.Dividends; Rights as Stockholder. Cash dividends on shares of Common Stock underlying the granted RSUs shall be credited to a dividend book entry account on behalf of the Participant, provided that any cash dividends shall be held uninvested and without interest, shall be subject to the same vesting conditions as the RSUs to which they relate, and shall be paid in cash at the same time that the shares of Common Stock underlying the Vested RSUs are delivered to the Participant in accordance with Section 4. Stock dividends on shares of Common Stock underlying the granted RSUs shall be credited to a dividend book entry account on behalf of the Participant, provided that any stock dividends shall be subject to the same vesting conditions as the RSUs to which they relate and shall be paid in shares of Common Stock at the same time that the shares of Common Stock underlying the RSUs are delivered to the Participant in accordance with Section 4. The Participant shall have no rights as a stockholder with respect to any shares of Common Stock underlying any RSU unless and until the Participant has become the holder of record of such shares.

6.Non-Transferability. No portion of the RSUs (or the shares of Common Stock underlying the RSUs) may be sold, assigned, transferred, encumbered, hypothecated or pledged by the Participant, other than to the Company as a result of forfeiture of the RSUs as provided in Section 3(d), unless and until the shares are delivered to the Participant in accordance with Section 4 and the Participant has become the holder of record of the shares.
