        <footnote id="F1">This Form 3 is being amended to correct the amount of common stock, par value $0.0001 per share (&quot;Common Stock&quot;) of Alternative Asset Management Acquisition Corp. (the &quot;Issuer&quot;), beneficially owned by Millenco LLC, a Delaware limited liability company (&quot;Millenco&quot;), upon becoming a 10% owner of the Issuer's Common Stock.</footnote>
        <footnote id="F2">Upon becoming a 10% owner of the Issuer's Common Stock on October 10, 2008, Millenco was the beneficial owner of 5,177,854 shares of the Issuer's Common Stock, of which 58,800 shares were a constituent part of the Issuer's units (&quot;Units&quot;).  Each Unit consists of one share of Common Stock and one warrant to purchase the Issuer's Common Stock (&quot;Warrant&quot;).</footnote>
        <footnote id="F3">Each Warrant entitles the holder to purchase one share of the Issuer's Common Stock at a price of $7.50. The Warrants will become exercisable commencing upon of the completion of the Issuer's initial business combination, provided that the Issuer has an effective registration statement covering the shares of Common Stock issuable upon the exercise of the Warrants.  The Warrants will expire on July 31, 2012, or earlier upon redemption. As of the date of this filing, the Issuer has not announced the completion of a business combination.</footnote>
        <footnote id="F4">As of October 10, 2008, in addition to the 58,800 Warrants held by Millenco as a constituent part of the Units, Millenco held an additional 3,587,900 Warrants.</footnote>
        <footnote id="F5">Millennium Management LLC, a Delaware limited liability company (&quot;Millennium Management&quot;), is the manager of Millenco, and consequently may be deemed to have shared voting control and investment discretion over securities owned by Millenco. Israel A. Englander (&quot;Mr. Englander&quot;) is the managing member of Millennium Management. As a result, Mr. Englander may be deemed to have shared voting control and investment discretion over securities deemed to be beneficially owned by Millennium Management. The foregoing should not be construed in and of itself as an admission by Millennium Management or Mr. Englander as to beneficial ownership of the shares owned by Millenco.</footnote>
        <footnote id="F6">As previously reported on the Form 3 filed with the Securities and Exchange Commission on November 3, 2008, Integrated Core Strategies (US) LLC, a Delaware limited liability company (&quot;Integrated Core Strategies&quot;) acquired the above-described shares of the Issuer's Common Stock on October 24, 2008, via an intercompany transfer between Millenco and Integrated Core Strategies, each of which is wholly-owned by the same entity.  For all filers except Millenco, such transfer was exempt under Rule 16a-13 promulgated under the Securities Exchange Act of 1934.</footnote>
