        <footnote id="F1">Upon the closing of the merger of NEON Communications, Inc. (&quot;NEON&quot;) with a subsidiary of Globix Corporation, each option to aquire NEON common stock became an option to purchase Globix common stock.  The number of shares of Globix common stock issuable pursuant to a NEON stock option is equal to the number of shares of NEON common stock subject to the NEON stock option, multiplied by 1.2748 and the exercise price per share of Globix common stock is equal to the exercise price per share of the NEON common stock subject to the NEON stock option divided by 1.2748.</footnote>
        <footnote id="F2">Mr. Cecin beneficially owns these shares pursuant to currently exercisable stock options.</footnote>
