Participant understands and acknowledges that if Participant is a director or shadow director of a U.K. Affiliate of the Company and the U.K. Affiliate is not wholly owned by the Company, Participant is subject to certain notification requirements under the Companies Act. Specifically, Participant must notify the U.K. Affiliate in writing of Participants interest in the Company and the number and class of Shares or rights to which the interest relates before the expiration of five days from the date on which the existence of the interest comes to his or her knowledge (e.g., within five days of receiving a notice of grant under the Plan). Participant must also notify the U.K. Affiliate when Participant acquires Shares under the Plan upon the vesting of the RSUs and again when Participant sells the Shares acquired under the Plan. This disclosure requirement also applies to any rights or Shares acquired by Participants spouse or children (under the age of 18).
