if the exercise of the Option following the cessation of the Participant’s status as a Service Provider (other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act, then the Option will terminate on the earlier of (i) the expiration of the term of the Option or (ii) the expiration of a period of thirty (30) days after the cessation of the Participant’s status as a Service Provider during which the exercise of the Option would not be in violation of such registration requirements.
