        <footnote id="F1">The Form 4 filed on May 21, 2014 (the &quot;Original Form 4&quot;) is being amended hereby to correct a typographical error that incorrectly indicated that the shares of FairPoint Communications, Inc. common stock in connection with the reported open market purchase by the Reporting Person were disposed of, rather than acquired, by the Reporting Person. All other information contained in the Original Form 4, including the amount of securities beneficially owned by the Reporting Person following the reported transaction, was accurate as of the date of its filing.</footnote>
