        <footnote id="F1">In connection with the closing of the Time Warner Cable Inc. transactions the merger exchange ratio of .9042 was applied to the exercise price and performance targets (divided by .9042) and the number of options (multiplied by .9042). As the grants occurred before the Time Warner Cable Inc. transactions, the number of shares, exercise prices and performance targets in this Form 4 were not adjusted for purposes of this filing.</footnote>
