would be determined by dividing the total outstanding amount to be converted by
the lesser of (i) 80% of the five-day moving average per share price of the
HyperFeed Shares on the date of conversion


                                       5

or (ii) 80% of $1.05 per share. The number of HyperFeed Shares issuable upon

business or changes in control or executive office; mergers or acquisitions;

Note, HyperFeed issued to Holdings a Warrant to Purchase 125,000 Shares of
Common Stock, at an exercise price of $1.05 per share (the "March 30, 2006
Common Stock Warrant"). The March 30, 2006 Common Stock Warrant may be exercised
