* All the shares beneficially held by the Reporting Person are shares of Class A
Common Stock, par value $0.01 per share, of the Issuer ("Class A Stock"). Each
share of Class A Stock is convertible into one share of Common Stock, par value
$0.01 per share, of the Issuer ("Common Stock") without consideration being paid
therefor. Each share of Class A Stock has two votes per share and each share of

of the outstanding shares of Class A Stock and (ii) approximately 40.04% of the
aggregate voting power of the Issuer assuming the shares of Class A Stock held
by the Reporting Person are not converted into shares of Common Stock. The
calculations are based on a total of 62,078,875 shares outstanding, consisting
of 29,763,375 shares of Common Stock and 32,315,500 shares of Class A Stock, as
last reported by Net2Phone in its Form 10-K for the fiscal year ended July 31,
