other value-added services for advertisers, television programmers, studios
and networks.

The Company received a warrant to acquire 2,500,000 shares of Livewire at $30
per share in connection with entering into the joint marketing agreement. The
warrant becomes exercisable at the rate of 500,000 shares per year,
commencing on April 13, 2001, includes a demand registration right, and may
be exercised until March 31, 2015. With certain exceptions, the warrant is
not transferable. As a result, the June 30, 2000 balance sheet has been
restated from amounts previously reported to record an investment and
deferred revenue in the amount of $76,016,175, the estimated value of the
warrant. The Company estimated the value of the warrant using the Black
Scholes pricing model with a risk free rate of 6.5%, a volatility of 80% and
assuming no cash dividends. For accounting purposes, the Company will
periodically estimate the value of the warrant. Any change in estimated value
attributable to shares that are both exercisable and are expected to become
registered within one year will be recorded through increases or decreases in
Other Comprehensive Income. The deferred income recorded by the Company will
be amortized into income over a period of 21 years, the contractual term of
the joint marketing venture commencing July 1, 2000 when the joint marketing
agreement becomes operationally effective.

A summary of the significant effects of the restatement are as
