[1] In the second quarter of 2013, 125 time-based and 83 (125 at maximum performance achievement) market performance-based stock options were rescinded with the consent of and without payment to the Chief Executive Officer (CEO) due to the fact that the original grants with respect to which these options were a part of exceeded the sub-limits of the applicable plan by the number of shares as to which the options were rescinded.
