        <footnote id="F1">1-for-1</footnote>
        <footnote id="F2">The amendment corrects the number of phantom stock units acquired on June 15, 2009 and the beneficial ownership amount in Box 9 of Table II.</footnote>
        <footnote id="F3">The phantom stock units were acquired by the Reporting Person pursuant to the terms of the Time Warner Inc. Deferred Compensation Plan (the &quot;Plan&quot;) in connection with the Issuer's quarterly cash dividend payment on its Common Stock and the Reporting Person's prior election to have a portion of the amounts deferred under the Plan track the performance of the Time Warner Common Stock Crediting Fund.  This transaction is exempt under Section 16(b).  The phantom stock units are settled in cash based on the Reporting Person's election either after a period of time not less than three years or following termination of employment.  The cash value received by the Reporting Person upon distribution will be based on the fair market value of the Common Stock.</footnote>
        <footnote id="F4">Includes previously acquired phantom stock units that have been adjusted to reflect a one-for-three reverse stock split of the Issuer's common stock that became effective on March 27, 2009.  Pursuant to the exemption under Rule 16a-9(a) of the Securities Exchange Act of 1934, these adjustment transactions are not required to be reported.</footnote>
