Form 3 (continued)

                             Attachment to Form 3


Reporting Person:  National Broadcasting Company Holding, Inc.

Address:           30 Rockefeller Plaza, New York, NY 10012

Issuer and Ticker Symbol:     Xoom.com, Inc. ("XMCM")

Date of Event Requiring Statement:   5/10/99

On May 9, 1999, National Broadcasting Company, Inc. and certain of its
affiliates (collectively, "NBC"), Xoom.com, Inc. ("Xoom") and certain of its
subsidiaries, CNET, Inc. ("CNET") and Snap! LLC entered into a series of
definitive agreements (the "Agreements") relating to the formation of a new
company to be named NBC Internet, Inc. ("NBCi") upon consummation of all the
transactions contemplated by the Agreements. NBCi is expected to include the
businesses of Xoom, Snap! LLC and certain of NBC's internet assets (including
NBC.com, Videoseeker.com and NBC Interactive Neighborhood) and a 10%
ownership interest in CNBC.com.  The first transaction will be effected by a
merger of Xoom with a subsidiary of NBCi followed by NBCi acquiring CNET's
ownership interest in Snap! LLC.  In a subsequent transaction, Neon Media
Corporation ("NMC"), a newly formed entity which will own the NBC internet
assets discussed above, is expected to be merged with NBCi and NBC's
ownership interests in Snap! LLC are expected to be contributed to NBCi.

In consideration of the Agreements, NBC, Xoom, Flying Disc Investments
Limited Partnership, a Nevada limited partnership ("Flying Disc") and Chris
Kitze (together with Flying Disc, the "Holders"), and CNET entered into a
Voting Agreement (the "Voting Agreement"), on May 9, 1999, pursuant to which,
among other things, the Holders (i) agreed to vote (or cause to be voted) all
of the shares beneficially owned by such Holders on the record date of such
vote or action (a) in favor of the adoption of the Agreements and the
approval of the terms thereof and each of the other transactions contemplated
by the Agreements; and (b) prior to the effective time of the merger of NMC
with NBCi, against certain business combination transactions and transactions
relating to the acquisition or purchase of 20% or more of the assets or any
class of equity securities of Xoom or any of its subsidiaries and against any
amendment of Xoom's certificate of incorporation or bylaws or other proposal,
action or transaction involving Xoom or any of its subsidiaries which
amendment or other action or transaction would reasonably be expected to
prevent or materially impede or delay the consummation of the transactions
contemplated by the Agreements and (ii) appointed NBC and the President and
Treasurer of NBC and the Secretary of NBC, in their respective capacities as
officers of NBC, and any individual who shall succeed to any such office of

                                  Page 6 of 7



NBC, and any other designee of NBC, each of them individually, such Holder's
proxy and attorney-in-fact (with full power of substitution) to vote or act
by written consent with respect to such Holder's shares of Common Stock.  The
Voting Agreement terminates on the earlier of (i) the consummation of the
merger of NMC with and into NBCi; and (ii) the termination of the agreement
pursuant to which the merger of NMC and NBCi will be effected. 

On May 9, 1999, the Holders beneficially owned 3,350,680 shares of the
Company Common Stock, which amounted to 19.5% of the total outstanding shares
of common stock of the Company.  These 3,350,680 shares of Common Stock
include 3,350,680 shares of Common Stock held by Flying Disc Investments
Limited Partnership ("Flying Disc"), a Nevada limited partnership, of which
Mr. Chris Kitze is a general partner.  Mr. Kitze may be deemed to be the
beneficial owner of the shares held by Flying Disc.

NBC is a wholly-owned subsidiary of National Broadcasting Company Holding,
Inc. NBC may be deemed to be, for purposes of Section 16 of the Securities
and Exchange Act of 1934, as amended (the "Exchange Act"), a beneficial owner
of all shares beneficially owned by the Holders, provided, however, that NBC
expressly disclaims any pecuniary interest in such shares.
