        <footnote id="F1">These shares of Common Stock, par value $.01 per share (&quot;Common Stock&quot;), of Aeroflex Holding Corp. (&quot;Aeroflex Holding&quot;) are held by VGG Holding LLC (&quot;VGG&quot;).  The Veritas Capital Fund III, L.P. owns 30.2% of the Class A membership interests of VGG.  AX Holding LLC owns 14.1% of the Class A membership interests of VGG.  A portion of the Class A membership interests of VGG held by The Veritas Capital Fund III, L.P. and by AX Holding LLC may be deemed attributable to the Reporting Person because the Reporting Person is (i) the President of Veritas Capital Partners III, L.L.C., which is the general partner of The Veritas Capital Fund III, L.P. and (ii) the managing member of the manager of AX Holding LLC.  The Reporting Person disclaims beneficial ownership of these shares to the extent such ownership exceeds the Reporting Person's pecuniary interest therein.</footnote>
        <footnote id="F2">Concurrently with the consummation of the initial public offering of Aeroflex Holding, VGG will issue Class B-1 membership interests representing an aggregate of 0.3% of the membership interests of VGG to certain members of Aeroflex Holding's management.  Pursuant to the terms of the limited liability company agreement of VGG, the issuance of such Class B-1 membership interests will reduce the percentage of the membership interests of VGG held by the holders of Class A membership interests of VGG on a pro rata basis.  Following such reduction, The Veritas Capital Fund III, L.P. and AX Holding LLC will indirectly beneficially own 26,135,830 shares of Common Stock of Aeroflex Holding that are held by VGG.</footnote>
