(2) Pro Forma Adjustments

     (a)  Reflects the purchase price that is allocated to goodwill (which will
          be amortized over 3 years) after adjusting for one full year of
          amortization.

The purchase price was allocated based on the estimated fair value of the
acquired assets and liabilities. The preliminary allocation is as follows
(in thousands):

Assets Acquired
         Cash                                          16,956

                                                      -------
Net Assets Acquired                                    12,894            12,894
                                                      -------         ---------
Goodwill                                                              $ 665,292


     (b)   Reflects the elimination of mySimon preferred and common stock,
           mySimon accumulated deficit, and reflects one year of goodwill
           amortization.

     (c)   Reflects the 10,725,927 shares of CNET's common stock and 364,730
           options issued for the acquisition of mySimon.

     (d)   Reflects the elimination of stock based compensation.

     (e)   Reflects one-year amortization of goodwill.

     (f)   Reflects three months amortization of goodwill.

     (g)  Reflects the adjustment for tax expense.

(3) Pro Forma Income/(Loss) Per Share

         The pro forma basic and diluted net income/(loss) per share calculation
assumes that the 10,725,927 shares of CNET's common stock and 364,730 options
issued in the acquisition were outstanding for the entire year in 1999. For the
three months ended March 31, 2000, the options are not included because their
effect is anti-dilutive.
