WHEREAS, pursuant to Section 12 of the Plan, the Board of Directors of Mattel (the “Board”) or the Compensation Committee thereof has the right to amend the Plan, provided, that the Plan may not be amended by the Board or Compensation Committee in any manner that is materially adverse to any Plan participant without such participant’s consent; and
