        <footnote id="F1">On August 6, 2004, the Board of Directors (&quot;Board&quot;) of Apollo Group, Inc. (&quot;Apollo&quot;) exercised its right under Apollo's Amended and Restated Articles of Incorporation to convert all outstanding shares of University of Phoenix Online common stock (&quot;UOPX Stock&quot;) to shares of Apollo Education Group Class A common stock (&quot;APOL Stock&quot;).  The Board set August 27, 2004, as the effective date for the conversion (&quot;Conversion&quot;).</footnote>
        <footnote id="F2">In connection with the Conversion, each outstanding share of UOPX Stock was converted into 1.11527 shares of APOL Stock in accordance with Apollo's Amended and Restated Articles of Incorporation which called for the conversion ratio to be based upon the relative market values of APOL Stock and UOPX Stock averaged over 20 trading days (July 9, 2004 through Aug. 5, 2004) ending five days prior to the announcement of the Conversion and includes a 10% premium on the value of UOPX Stock.</footnote>
        <footnote id="F3">By self as trustee of the Aurora Foundation dated May 22, 1997.  Previous forms referred to this foundation as the Sperling Foundation.</footnote>
        <footnote id="F4">By self as co-trustee and a beneficiary of the John Sperling 1994 Irrevocable trust dated April 27, 1994.</footnote>
        <footnote id="F5">By self as trustee and beneficiary of the John G. Sperling Revocable Trust dated January 31, 1995.</footnote>
        <footnote id="F6">In connection with the Conversion, each outstanding option of UOPX Stock was converted into options of APOL Stock based on the ratio of the closing stock price of APOL Stock and UOPX Stock on August 12, 2004.</footnote>
        <footnote id="F7">25% of the shares covered  by this option shall vest on each of the following dates: 8/31/02, 8/31/03, 8/31/04 and 8/31/05.  The vesting shall accelerate if certain earnings per share goals are achieved.  On February 28, 2002, 100% of the option became vested because the earnings per share goal was achieved.</footnote>
        <footnote id="F8">25% of the shares covered by this option shall vest on each of the following dates: 8/31/02, 8/31/03, 8/31/04 and 8/31/05.  The vesting shall accelerate if certain earnings per share goals are achieved.   As of 8/31/03, these goals were achieved, therefore, the options covered by this grant are 100% vested.</footnote>

The vesting shall accelerate if certain operational  goals are achieved.  On 8/31/03 some of these goals were achieved, thus an additional 25% of the options under this grant became exercisable.</footnote>
