        <footnote id="F1">Pursuant to the merger (the &quot;Merger&quot;) of a wholly-owned subsidiary of Intelsat (Bermuda), Ltd. (&quot;Intelsat&quot;) with and into PanAmSat Holding Corporation (&quot;PanAmSat&quot;), each outstanding share of common stock of PanAmSat (the &quot;Common Stock&quot;) was converted into the right to receive $25.00, plus approximately $0.00927 as the pro rata quarterly dividend, per share in cash without interest.  As a result of the Merger, PanAmSat became a wholly-owned subsidiary of Intelsat, and the Common Stock was delisted from the New York Stock Exchange.</footnote>
