For Restricted Share Units, the Committee shall designate, at the time of grant of Restricted Share Units, the date or dates on which all or a portion of the Restricted Share Units shall become Vested Units subject to any terms or conditions determined under [Section 4.6]. Unless otherwise determined by the Committee to be earlier, and subject to Article 6 the Vesting Date shall be the third anniversary of the Grant Date in respect of any grant of Restricted Share Units. The Committee may, subsequent to the Grant Date, but prior to the Vesting Date designated at the time of grant, designate an earlier date for vesting of all or any portion of Restricted Share Units then outstanding and granted to a Participant under the Plan, in which event such unvested Restricted Share Units shall be deemed to be Vested Units on such earlier date.

Time Vesting of Restricted Share and Restricted Share Unit Awards. Restricted Shares or Restricted Share Units, or portions thereof, are exercisable at such time or times as determined by the Committee in its discretion at or after grant, subject to the restrictions on time Vesting set forth in this Section. If the Committee provides that any Restricted Shares or Restricted Share Unit Awards become Vested over time (with or without a performance component), the Committee may waive or accelerate such Vesting provisions at any time, subject to the restrictions on time Vesting set forth in this Section. Unless otherwise determined by the Committee in connection with the grant and set forth in the Award Agreement, all unvested Restricted Share and Restricted Share Unit Awards shall immediately Vest with respect to any required time vesting upon the Death or Disability of the holder.
