                                  UNAUDITED PRO FORMA
                        CONDENSED COMBINED FINANCIAL INFORMATION

The total estimated purchase consideration of the Paralogic Software
Corporation merger has been allocated on a preliminary basis to assets and
liabilities based on management's estimate of their fair values. The excess
of the purchase cost over the fair value of the net assets acquired has been
allocated to goodwill. This allocation is subject to change pending the
completion of the final analysis of the fair value of the assets acquired and
liabilities assumed. The impact of these changes could be material.

The adjustments to the unaudited pro forma condensed combined balance sheet as
of March 31, 1999 have been calculated as if the merger occurred on March 31,
1999 and are as follows:

(1)  To reflect the acquisition of Paralogic Software Corporation for a total
estimated purchase price of approximately $35,396,000.  The purchase
consideration consists of the following:

     -    Issuance of 654,018 shares of Xoom.com's Common Stock, with an
          estimated fair value of $30,824,000.  The fair value per share of
          XOOM.com's common stock issued is based on the average closing price
          of XOOM.com's common stock on June 17, 1999 (the day the merger was
          announced) and the three days prior and subsequent to such date.

     -    Assumption of options to purchase 94,734 shares, respectively, of
          XOOM.com's Common Stock with a fair value of $4,257,000.  The fair
          value of the options assumed is based on the Black-Scholes model
          using the following assumptions:

          -    Fair market value of the underlying shares is based on the
               average closing price of XOOM.com's common stock on June 17, 1999
               (the day the merger was announced) and the three days prior and
               subsequent to such date
          -    Expected life of 3 years
          -    Expected volatility of 1.0
          -    Risk-free interest rate of 5.16%
          -    Expected dividend rate of 0%

     -    Other related transaction and merger costs estimated to be $315,000.

(2)  Recognition of the excess purchase cost of $33,577,000 over the fair value
of the net assets acquired, have been recorded as goodwill and other intangible
assets as follows:


                                             
          -    Developed Technology             $ 1,212,000
          -    Core Technology                    3,774,000
          -    Acquired workforce                    80,000
          -    Goodwill                          28,511,000
                                                -----------
                                                $33,577,000
                                                -----------
                                                -----------


(3)  To reflect the elimination of the historical stockholders' equity accounts
     of Paralogic

(4)  Recognition of purchased in-process research and development charge of
     $1,522,000

(5)  To eliminate the estimated gross margin associated with the Paralogic
     Software Corporation deferred revenue

The adjustments to the unaudited pro forma condensed combined consolidated
statements of operations for the year ended December 31, 1998 and the three
months ended March 31, 1999 have been calculated assuming that the merger
occurred as of January 1, 1998 and January 1, 1999, respectively and are as
follows:



(A)  The purchased in-process research and development charge of $1,522,000 has
     been excluded from net loss for the year ended December 31, 1998 and the
     three months ended March 31, 1999, as it represents a non-recurring charge.
     The charge will be recorded in the three months ended June 30, 1999.

(B)  To reflect the amortization of goodwill and other intangible assets
     resulting from the merger.  The goodwill and other intangible assets are
     being amortized over periods of four years.

(C)  Basic and diluted net loss per share reflects the issuance of 654,018
     shares of XOOM.com's common stock, as if the shares had been outstanding
     for the entire period.  The effect of stock options issued assumed in the
     merger have not been included, as their inclusion would be anti-dilutive.
