November   , 1999
Dear Xoom.com Stockholder:


    I am pleased to send you this proxy statement/prospectus for a special
meeting of the stockholders of Xoom.com. At the meeting, you will be asked to
approve agreements entered into by Xoom.com and two of its subsidiaries, NBC and
affiliates of NBC, CNET and SNAP, relating to the formation of a new company to
be named NBC Internet, Inc., and referred to as NBCi. The new company, NBCi,
would combine the businesses of Xoom.com, SNAP and three Internet-related
businesses of NBC, as well as a 10 percent equity interest in CNBC.com. You will
also be asked at the meeting to approve the NBCi 1999 stock incentive plan.

    Upon the closing of the transactions described in this proxy
statement/prospectus, stockholders of Xoom.com are expected to own approximately
38.8 percent of the outstanding common stock of NBCi, CNET is expected to own
approximately 13.8 percent and affiliates of NBC are expected to own
approximately 47.3 percent. The NBC affiliates involved in the transactions have
the ability to increase their ownership percentage to approximately 52.6 percent
in the future upon the exercise in full of two convertible notes issued by NBCi.

    For each share of common stock of Xoom.com that you own, you will receive
one share of Class A common stock of NBCi. Currently, there is no public market
for NBCi shares. NBCi, however, has applied to have the shares of Class A common
stock approved for listing on the Nasdaq National Market under the symbol
"NBCI." Upon the closing of the transactions, NBCi expects to have approximately
27,365,472 shares of its Class A common stock outstanding, of which 20,120,409
shares are being registered. Affiliates of NBC will receive shares of Class B
common stock of NBCi. The Class A common stock and the Class B common stock are
the same in all respects, except for important governance rights, the fact that
only the Class A common stock will be publicly traded and that only NBC and its
affiliates may own the Class B common stock.

    BEFORE YOU MAKE A DECISION, YOU SHOULD CONSIDER THE "RISK FACTORS" BEGINNING
ON PAGE 18 OF THIS PROXY STATEMENT/PROSPECTUS.

    THE BOARD OF DIRECTORS OF XOOM.COM HAS APPROVED THE PROPOSED TRANSACTIONS
AND RECOMMENDS THAT YOU VOTE FOR THE PROPOSALS. IN ADDITION, I HAVE AGREED TO
VOTE ALL SHARES OF XOOM.COM COMMON STOCK THAT I BENEFICIALLY OWN IN FAVOR OF THE
TRANSACTIONS.

    Please use this opportunity to take part as a stockholder of Xoom.com by
voting. Whether or not you plan to attend the meeting, please complete, sign,
date and return the accompanying proxy card in the enclosed self-addressed
stamped envelope, to ensure your shares are voted at the meeting. YOUR VOTE IS
VERY IMPORTANT, SO PLEASE TAKE THE TIME TO VOTE YOUR SHARES.

                  QUESTIONS AND ANSWERS ABOUT THE TRANSACTIONS

Q: WHAT IS XOOM.COM PROPOSING TO DO? HOW WILL I BENEFIT?
    A: Xoom.com is proposing to become part of a new Internet company, NBCi.
Upon completion of the transactions, NBCi will include the businesses of:
    - Xoom.com, the owner of www.xoom.com, one of the fastest-growing community-
      based sites on the Internet from July 1998 to July 1999, according to
      Media Metrix based on the percentage increase in reach among home and work
      users,

    - SNAP, the owner of www.snap.com, one of the fastest-growing major Internet
      portals from July 1998 to July 1999, according to Media Metrix based on
      the percentage increase in reach among home and work users, and

    - selected Internet assets of a subsidiary of NBC, a wholly owned subsidiary
      of General Electric Company. NBC was the most watched television network
      among adults age 18 to 54 in the United States for the television season
      that ended in May 1999, according to Nielsen Media Research.
    Under its umbrella consumer brand SNAP, NBCi will integrate portal,
community and e-commerce services throughout the NBCi Web sites. Xoom.com
stockholders will have a stake in one of the first publicly traded Internet
companies combining these services in a strategic relationship with a major
broadcast television network. Xoom.com believes, based on these attributes, that
NBCi will be well positioned to capitalize on the growth opportunities available
in the Internet industry.
Q: WHAT IS SNAP.COM? WHO OWNS IT NOW?
    A: SNAP, through the Snap.com Web site, develops and provides Web-based
tools that help users access, navigate and personalize the vast resources of the
Internet. SNAP is primarily owned by NBC and CNET. CNET is a publicly traded
media company that provides consumers with information online and on television
regarding computers, the Internet and digital technologies.

Q: WHAT ARE THE NBC CONTRIBUTED INTERNET ASSETS THAT WILL BE PART OF NBCI?

    A: The NBC contributed Internet assets consist of NBC's businesses related
to three separate Internet properties, together with a 10% equity interest in a
fourth Internet business, namely:

    - NBC.com (www.nbc.com), a Web site that provides entertainment information
      and specially designed Web spin-offs of popular NBC televisions programs,
      as well as chat and bulletin board services related to NBC's network
      television programming.

    - NBC-IN.com (www.nbc-in.com), a portal service that provides access to
      local content via the Web sites of over 100 television stations owned by
      or affiliated with NBC. NBC-IN fills out the offerings of the local
      stations' Web sites by delivering customized content relating to real
      estate, job searches, automobiles and various other topics.

    - VideoSeeker (www.videoseeker.com), a Web site that offers a large and
      comprehensive selection of on-demand video programming, including
      entertainment news, movie trailers, television clips and interviews.

    - A 10% equity interest in CNBC.com LLC, which owns the CNBC.com Web site
      (www.cnbc.com). The CNBC.com Web site was launched on June 21, 1999 and
      provides comprehensive financial information and analytic tools on the
      Web. CNBC.com also offers personal finance commentary and data, community
      features and other services designed to satisfy an individual's financial
      planning needs.

Q: HOW IS NBCI GOING TO BE CREATED?

    A: NBCi will be created through a series of transactions occurring on
successive days.

                                       1
<PAGE>
    On the first day, Xoom.com will be merged with a subsidiary of NBCi, and
CNET and GlobalBrain.net, Inc., an unaffiliated third party, will contribute
their ownership interests in SNAP to NBCi. The following charts illustrate the
transactions contemplated by the merger agreement:
[Diagram illustrating merger of Xenon 3 with Xoom.com]
[Diagram illustrating transfer of CNET's ownership in SNAP to NBCi]
[Diagram illustrating ownership structure after closing of merger agreement]
    Immediately thereafter, on the succeeding day, Neon Media Corporation, a
newly formed entity that will own the businesses related to NBC.com and
NBC-IN.com and a 10% equity interest in CNBC.com LLC, will be merged with NBCi.
At the same time, NBC Multimedia, a subsidiary of NBC, will contribute its
ownership interests in SNAP to NBCi. NBC Multimedia will also transfer the
business related to VideoSeeker.com to NBCi in exchange for a convertible note
of NBCi. In addition, GE Investments Subsidiary, an affiliate of NBC, will
purchase a second convertible note from NBCi in exchange for the assignment to
NBCi of a $340 million note issued by NBC. Thereafter, it is intended that NBCi
will transfer the Internet assets contributed by NBC into a newly formed, wholly
owned subsidiary of NBCi. Upon the conclusion of the transactions, NBCi will be
owned principally by NBC affiliates, CNET and the former stockholders of
Xoom.com.

    The following charts illustrate the transactions contemplated by the
contribution agreement:

[Diagram illustrating merger of Neon Media Corporation with NBCi]
[Diagram illustrating the transfer of NBC Multimedia's ownership interest in
SNAP and the assets of VideoSeeker.com to NBCi]

                                       2
<PAGE>
[Diagram illustrating owndership structure after closing of all transactions]
    We expect that NBCi's holding company structure will increase operating and
structural flexibility, minimize regulatory concerns and isolate risks of its
business.
Q: CAN THE TRANSACTIONS ON THE FIRST DAY HAPPEN WITHOUT THE TRANSACTIONS ON THE
  SECOND DAY?

    A: While the transactions on the first day could happen without the
transactions on the second day occurring, it is intended that all the
transactions will occur as part of a series of steps in the formation of NBCi.
If the transactions on the second day do not close, however, NBCi will lose its
right to use "NBC" in its name. The net effect of the transactions on the first
day will be the acquisition by Xoom.com of an equity interest in SNAP. It is a
condition to the closing of the transactions contemplated by the merger
agreement that all of the conditions set forth in the contribution agreement
have been satisfied or waived. See page 32 for a discussion of the risks if the
transactions contemplated by the contribution agreement do not occur.

Q: CAN I VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT AND AGAINST XOOM.COM'S
  ADOPTION OF THE CONTRIBUTION AGREEMENT?
    A: Yes. If the requisite majority votes against Xoom.com's adoption of the
contribution agreement, the board of directors of Xoom.com has agreed to cause
Xoom.com to vote against adoption of the contribution agreement. If the
requisite majority votes against the adoption of the merger agreement, the
transactions contemplated by the merger agreement and the contribution agreement
will not occur. See page 45.
Q: WHAT ARE NBCI AND XENON 3?
    A: NBCi and Xenon 3 are companies newly formed at the direction of Xoom.com
for the purpose of effecting the transactions. Xenon 3 is a subsidiary of NBCi
that will be merged with Xoom.com on the first day. On the second day, Neon
Media Corporation will merge into NBCi.

Q: WHAT WILL XOOM.COM STOCKHOLDERS BE ENTITLED TO AS A RESULT OF THE
  TRANSACTIONS?

    A: Xoom.com stockholders will be entitled to receive one share of NBCi Class
A common stock in exchange for each share of Xoom.com common stock they hold.
Upon completion of the transactions, Xoom.com's former stockholders, other than
NBC and its affiliates, are expected to own approximately 20,120,409 shares of
Class A common stock of NBCi, representing approximately 38.8% of NBCi's
outstanding common stock upon the closing of the transactions.

Q: WHAT DOES CNET RECEIVE?

    A: In exchange for its ownership interests in SNAP, CNET will receive
7,147,584 shares of NBCi Class A common stock, which is expected to represent
approximately 13.8% of NBCi's outstanding common stock upon the closing of the
transactions. The shares of Class A common stock owned by CNET will not be
registered under this proxy statement/prospectus.

Q. WHAT DOES NBC RECEIVE?

    A.  On July 30, 1999 NBC acquired 960,028 shares of Xoom.com common stock
under a stock purchase agreement dated June 11, 1999. As a result, in connection
with the merger of Xoom.com with Xenon 3, an affiliate of NBC will receive
960,028 shares of Class A common stock that will convert into Class B common
stock in connection with the merger of Neon Media Corporation and NBCi. In
exchange for NBC Multimedia's ownership interests in SNAP and in connection with
the merger of Neon Media Corporation with NBCi, NBC Multimedia will receive
23,590,680 shares of NBCi Class B common stock in addition to the 960,028 shares
discussed above. Affiliates of NBC are expected to own approximately 47.3% of
NBCi's outstanding common stock upon the closing of the transactions. Under the
contribution

                                       3
<PAGE>
agreement, NBC and its affiliates will also receive two convertible notes of
NBCi. Assuming no issuances of additional shares of common stock by NBCi, if
both NBCi convertible notes are converted after one year, NBC and its affiliates
could own approximately 52.6% of NBCi's outstanding common stock.
Q: WHAT'S THE DIFFERENCE BETWEEN THE CLASS A COMMON STOCK AND THE CLASS B COMMON
  STOCK OF NBCI?

    A: NBCi will initially have two classes of common stock: Class A common
stock and Class B common stock. The Class A common stock and the Class B common
stock are the same in all respects except for important governance rights, the
fact that only the Class A common stock will be publicly traded and that only
NBC and its affiliates may hold shares of Class B common stock. Upon the
transfer of Class B common stock to any person other than NBC or any of its
affiliates, such Class B common stock will automatically convert into Class A
common stock. See page 216 for a description of the NBCi common stock.

Q: WHAT ARE THE DIFFERENCES IN GOVERNANCE RIGHTS BETWEEN THE CLASS A COMMON
  STOCK AND THE CLASS B COMMON STOCK?
    A: Under NBCi's restated certificate of incorporation, the holders of the
Class B common stock initially have the right to elect six of the 13 members of
the NBCi board of directors. The holders of the Class B common stock will retain
this right so long as such holders beneficially own at least 20% of the
outstanding shares of common stock of NBCi. The holders of the Class A common
stock will have the right to elect the remaining seven members, with the
nomination of the seventh member requiring the approval of at least seven
members of the NBCi board of directors.

    If, and for so long as, NBC and its affiliates would own 35% or more of the
outstanding shares of NBCi common stock following conversion of the NBCi
convertible notes in full, the holders of the Class B common stock would have
the right to appoint seven of the 13 members of the NBCi board of directors. The
holders of the Class A common stock will have the right to appoint the remaining
six members. As long as the directors elected by the holders of the Class B
common stock do not constitute a majority of the NBCi board of directors,
several significant corporate actions by NBCi will require the approval of the
Class B Directors. As long as the holders of the Class B common stock have the
right to elect seven members to the NBCi board of directors, several significant
corporate actions by NBCi will require the approval of the Class A Directors.
See page 219 for a description of these governance rights.


Q: WHO IS GOING TO RUN NBCI?

    A: Robert C. Wright, the president and chief executive officer of NBC, will
be the chairman of the board of NBCi, and Chris Kitze, the chairman of the board
of Xoom.com, will be the chief executive officer of NBCi. The designees to the
initial board of directors of NBCi are set forth on page 126. NBCi will be
managed principally by individuals that currently manage Xoom.com and SNAP. See
page 126 for a description of the other executive officers and key employees of
NBCi.

Q: WHAT WILL HAPPEN TO XOOM.COM AFTER THE MERGER?

    A: Xoom.com will become a wholly owned subsidiary of NBCi and will continue
to operate its Web site at www.xoom.com. NBCi will, however, integrate the
Xoom.com Web site with the other NBCi Internet assets under the consumer brand
SNAP, at www.snap.com, as described more fully on page 114. Users will be able
to access Xoom.com from the Snap.com Web site or from the current Xoom.com
address.

Q: WHAT WILL HAPPEN TO THE NBC.COM, NBC-IN.COM AND VIDEOSEEKER.COM WEB SITES?

    A: After the closing of the transactions, the NBC.com, NBC-IN.com and
VideoSeeker.com Web sites will be integrated into the Snap.com Web site. Users
will be able to access these Web sites from the Snap.com Web site or from the
current Web site address of each Web site.

Q: WHAT AM I VOTING ON?

    A: You will vote on whether to adopt the merger agreement, whether to
approve Xoom.com's adoption, as the sole stockholder of

                                       4
<PAGE>
NBCi, of the contribution agreement and whether to approve the stock incentive
plan.
Q: DOES THE BOARD OF DIRECTORS OF XOOM.COM RECOMMEND VOTING IN FAVOR OF THE
  TRANSACTIONS?
    A: Yes. After careful consideration, Xoom.com's board of directors
recommends that you vote to adopt the merger agreement and vote in favor of
Xoom.com's adoption of the contribution agreement. Xoom.com's board of directors
also recommends that you vote to approve the stock incentive plan.
    For a more complete description of the recommendation of the board of
directors of Xoom.com, see page 50.
Q: ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
  TRANSACTIONS?
    A: Yes. In evaluating the transactions, you should carefully consider the
factors discussed in the section entitled "Risk Factors" on page 18.
Q: AM I ENTITLED TO DISSENTERS' OR APPRAISAL RIGHTS?
    A: No. Under Delaware law, holders of Xoom.com common stock are not entitled
to dissenters' or appraisal rights in connection with the proposed transactions.
Accordingly, if you vote against the adoption of the merger agreement and
against Xoom.com's adoption of the contribution agreement, but such agreements
are nevertheless adopted, you will become a stockholder of NBCi.
Q: WHAT DO I NEED TO DO NOW?
    A: Mail your signed proxy card in the enclosed return envelope as soon as
possible so that your shares may be represented at the special meeting of
Xoom.com's stockholders. If you do not include instructions on how to vote your
properly signed proxy, your shares will be voted "FOR" the adoption of the
merger agreement, "FOR" approval of Xoom.com's adoption of the contribution
agreement and "FOR" approval of the stock incentive plan.
Q: WHAT DO I DO IF I WANT TO CHANGE MY VOTE?
    A: If you want to change your vote, send the secretary of Xoom.com a
later-dated, signed proxy card before the special meeting or attend the Xoom.com
meeting and vote in person. You may also revoke your proxy by sending written
notice to the secretary of Xoom.com before the special meeting.

    For a more complete description of how to change your vote, see page 44.

Q: IF MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
  SHARES FOR ME?

    A: Your broker will vote your shares only if you provide instructions on how
to vote by following the information provided to you by your broker. If you do
not instruct your broker on how to vote, your shares will not be voted at the
special meeting. This will have the same effect as voting against the adoption
of the merger agreement, but will not constitute a vote against Xoom.com's
adoption of the contribution agreement or against the approval of the stock
incentive plan.

    For a more complete description of voting shares held in "street name," see
page 45.

Q: SHOULD I SEND IN MY XOOM.COM STOCK CERTIFICATES NOW?

    A: No. After the transactions are completed, NBCi will send you written
instructions for exchanging your Xoom.com stock certificates for NBCi stock
certificates.

Q: WHEN DO YOU EXPECT THE TRANSACTIONS TO BE COMPLETED?

    A: Xoom.com is working toward completing the transactions as soon as
possible after the special meeting. Xoom.com hopes to complete the transactions
in November 1999.

    For a more complete description of the conditions to the transactions, see
pages 74 and 80.

Q: WHOM SHOULD I CALL WITH QUESTIONS?

    A: Please call Xoom.com Investor Relations at (415) 288-2500 or send an
e-mail to [email protected] with any questions about the merger. You
may also call Innisfree M&A Incorporated, the proxy solicitation firm retained

    You may also obtain additional information about Xoom.com from documents it
files with the Securities and Exchange Commission by following the instructions
in the section entitled "Where You Can Find More Information."

    - by either NBC or NBCi if the transactions contemplated by the contribution

      receives, having complied in all material respects with the provisions of
      the contribution agreement, a BONA FIDE proposal to acquire Xoom.com and
      the Xoom.com board of directors determines in good faith in consultation
      with its financial and legal advisers, that:
        - the proposal is more favorable to the Xoom.com stockholders than the
          transactions contemplated by the merger agreement and the contribution
          agreement; and
        - termination of the contribution agreement is required to comply with
          its fiduciary duties;

    - by either NBC or NBCi if there has been a material default or breach of
      the contribution agreement by NBC, if NBCi is terminating the contribution
      agreement, or by NBCi or Xoom.com, if NBC is terminating the contribution
      agreement, and such default or breach is not curable or, if curable, is
      not cured within 30 days after written notice of such default or breach;
      or

    - automatically and without any action by the parties upon the termination
      of the merger agreement.

RELATED AGREEMENTS (PAGE 90)

    NBC STOCK OPTION (PAGE 90)

    In connection with the execution of the contribution agreement, Xoom.com
granted NBC a stock option to purchase up to 3,415,249 shares of Xoom.com common
stock at a price of $73.50 per share. This number represented approximately
19.9% of the outstanding shares of Xoom.com at the time the contribution
agreement was signed. The stock option is not currently exercisable. However, if
the contribution agreement is terminated because the required approval of
Xoom.com's stockholders is not obtained and other conditions exist or if another
triggering event occurs, NBC may be able to exercise the stock option. The
triggering events are described on page 90. If the contribution agreement is
consummated in accordance with its terms, the stock option will terminate.

    NBC required Xoom.com to grant the stock option as a condition to entering
into the contribution agreement. The stock option and the non-solicitation
provisions of the contribution agreement may discourage third parties who are
interested in acquiring a significant stake in Xoom.com and are intended to
increase the likelihood that the transactions will be completed.

                                       9
<PAGE>
    VOTING AGREEMENT (PAGE 94)
    Chris Kitze, Xoom.com's Chairman and, through a company he controls, the
owner of approximately 16.4% of Xoom.com outstanding common stock, has agreed to
vote all of his shares of Xoom.com common stock to adopt the merger agreement
and to approve Xoom.com's adoption of the contribution agreement.
    BRAND INTEGRATION AND LICENSE AGREEMENT (PAGE 95)
    In connection with the transactions, NBC and NBC Multimedia entered into a
licensing agreement. This agreement will become an asset of NBCi and be binding
on NBC with respect to NBCi upon consummation of the transactions. Among other
rights, the agreement grants NBC Multimedia a non-exclusive license to use the
trademark "NBC", the NBC peacock logo and the NBC soundmark in connection with
NBC.com, VideoSeeker and NBC-IN.com and the portal, community and e-commerce
services of NBCi. In addition, NBC may not license competitors of NBC Multimedia
to co-brand their portal, community and e-commerce services with specified NBC
marks, and NBC may not operate such services itself, other than through NBC
Multimedia. The license agreement also provides NBC Multimedia an exclusive
license to use, reproduce and display short excerpts from television programs
owned entirely by NBC or to which NBC has all rights necessary to provide
interactive delivery rights to NBC Multimedia and to create interactive programs
therefrom on the NBC Multimedia Web sites, in accordance with the terms of the
license.
    The license agreement also provides NBC Multimedia with license rights to
the Web site addresses for NBC.com, NBC-IN.com and VideoSeeker.com, although NBC
retains title to such addresses.
    ADVERTISING AGREEMENT (PAGE 96)
    NBC and NBCi will enter into an agreement to purchase at least $405 million
of advertising on NBC's television properties including the NBC Television
Network, CNBC, MSNBC and NBC's owned and operated television stations over the
next four years. At the end of the four year period, NBC and NBCi have agreed to
negotiate concerning the purchase of an additional $500 million of advertising
on NBC during the following six years.

    GOVERNANCE AGREEMENT (PAGE 97)

    NBC and NBCi will enter into an agreement with respect to the governance of
NBCi, the form of which was negotiated in connection with the contribution
agreement. Pursuant to the governance agreement, NBC will enter into a
standstill agreement with NBCi under which it will agree not to transfer or
acquire additional shares of NBCi's capital stock except in the case of a third
party tender offer or if NBCi agrees to enter into a relationship that would
result in a change in control. The governance agreement will also contain
provisions with respect to NBC's rights to purchase additional shares of Class B
common stock in the event NBCi issues shares of capital stock in order to
maintain its percentage ownership interest in NBCi.

    OTHER AGREEMENTS WITH CNET (PAGE 97)

    In connection with the transactions, CNET will enter into a voting and right
of first offer agreement with NBC under which CNET will

    - agree to vote its shares of Class A common stock in the same manner as NBC
      and its affiliates with respect to change in control transactions
      involving NBCi, and

    - provide NBC with a right of first offer to purchase shares of Class A
      common stock owned by CNET.

    CNET will also enter into a standstill agreement with NBCi under which it
will agree not to transfer or acquire additional shares of NBCi's capital stock
except transfers in connection with a third party tender offer or a merger,
consolidation or reorganization of NBCi.

    AMENDMENT TO CNET CARRIAGE AGREEMENT (PAGE 97)

    In connection with the transactions, CNET, SNAP and NBC and its affiliates
entered into an

                                       10
<PAGE>
amendment to their existing carriage agreement. Under the amendment, specified
information provided by CNET will receive preferred placement on SNAP's Web
sites. The amendment also provides that SNAP will be a preferred provider of
directory services on any CNET Web site and contains limited provisions
restricting CNET's ability to compete with SNAP, both of which expire on May 9,
2000.
    XOOM.COM/NBC STOCK PURCHASE AGREEMENT (PAGE 98)
    On June 11, 1999, Xoom.com and NBC entered into a stock purchase agreement.
Under the agreement, on July 30, 1999 NBC acquired 960,028 shares of Xoom.com's
common stock, which at that time represented approximately 5.0% of Xoom.com's
outstanding shares, for $55 million. NBC has agreed to vote all of such shares
in favor of the adoption of the merger agreement and in favor of Xoom.com's
adoption of the contribution agreement.
REASONS FOR THE TRANSACTIONS (PAGE 50)
    The Xoom.com board of directors considered a number of factors in
determining to approve the transactions and recommend approval of them to its
stockholders, including the opportunity of Xoom.com's stockholders to
participate in the potential growth of NBCi following the closing of the
transactions, the value of NBC's name and trademarks, the enhanced financial and
operational resources of NBCi, and the enhanced ability of NBCi to take
advantage of future strategic opportunities.
OPINIONS OF FINANCIAL ADVISORS TO XOOM.COM (PAGES 53 AND 61 AND APPENDIX C-1 AND
  APPENDIX C-2)
    In deciding to approve the transactions, Xoom.com's board of directors
considered the opinions of Bear, Stearns & Co. Inc. and Hambrecht & Quist LLC,
its financial advisors, that, as of May 9, 1999, after issuance of NBCi shares
to Xoom.com stockholders in the merger of Xenon 3 with Xoom.com, the aggregate
issuance of NBCi shares to NBC and CNET in the transactions contemplated by the
merger agreement and the contribution agreement, taken together, both before and
after conversion of the NBCi convertible notes, in exchange for the aggregate
contribution of SNAP and the NBC contributed Internet businesses, was fair, from
a financial point of view, to Xoom.com. In addition, Xoom.com's board of
directors considered the opinion of Bear Stearns that, after issuance of NBCi
shares to Xoom.com stockholders in the merger of Xenon 3 with Xoom.com, the
issuance of NBCi shares to CNET in the transactions contemplated by the merger
agreement, if the transactions contemplated by the contribution agreement are
not consummated, in exchange for CNET's contribution of its equity interests in
SNAP, was fair, from a financial point of view, to Xoom.com and its
stockholders. Such opinions were provided for the information and assistance of
Xoom.com's board of directors in connection with the transactions and do not
constitute a recommendation as to how any holder of shares of Xoom.com common
stock should vote with respect to the transactions. The full text of the written
opinions of each of Bear Stearns and Hambrecht & Quist, which set forth
assumptions made, matters considered and limitations on the review undertaken in
connection with the opinions, are attached as Appendix C-1 and Appendix C-2. You
are urged to read such opinions in their entirety.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF XOOM.COM IN THE TRANSACTIONS
  (PAGE 68)

    In considering Xoom.com's board of directors' recommendation that you vote
to approve the adoption of the merger agreement and vote to approve Xoom.com's
adoption of the contribution agreement, you should note that the officers and
directors of Xoom.com have interests in the transactions that are different
from, or in addition to, your interests. These interests include accelerated
vesting of stock options and indemnification rights. Specifically, the closing
of the transactions will result in the accelerated vesting of options relating
to 527,389 shares of Xoom.com common stock held by the executive officers and
directors of Xoom.com. As a result, directors and officers may be more likely to
vote to approve the transactions than Xoom.com's stockholders generally.

                                       11
<PAGE>
THE SPECIAL MEETING (PAGE 44)
    At the meeting of Xoom.com, you will be asked to consider and vote upon the
adoption of the merger agreement, and Xoom.com's adoption of the contribution
agreement and the transactions contemplated thereby, including the merger of
Xoom.com with Xenon 3. You also will be asked to approve the stock incentive
plan. Xoom.com will initially pay the costs of soliciting proxies for the
special meeting. If the transactions contemplated by the merger agreement close,
NBCi will be responsible for these expenses.
STOCKHOLDER APPROVAL (PAGE 45)
    The holders of a majority of the outstanding shares of Xoom.com common stock
must vote for adoption of the merger agreement. Although not required by
Delaware law, the board of directors of Xoom.com is seeking approval by the
holders of a majority of the shares of Xoom.com common stock present in person
or by proxy at the meeting and entitled to vote of (A) Xoom.com's adoption of
the contribution agreement, and (B) the stock incentive plan.
    As of the record date, Mr. Kitze, including his affiliates, and NBC,
collectively owned 4,310,708 shares or approximately 21.1% of the Xoom.com
outstanding common stock. Mr. Kitze and NBC have agreed to vote their shares in
favor of the transactions. Accordingly, the vote of stockholders owning an
additional 5,920,678 shares or 28.9% of Xoom.com common stock is required to
approve both the merger agreement, contribution agreement and the stock
incentive plan, assuming all shares of Xoom.com common stock are present in
person or by proxy at the meeting.
    As of the record date, the executive officers and directors of Xoom.com and
their affiliates collectively owned 3,966,986 shares of Xoom.com common stock
representing approximately 19.4% of the outstanding shares.
NASDAQ LISTING (PAGE 73)
    NBCi has applied to have the Class A common stock listed on The Nasdaq
National Market under the symbol "NBCI." It is a condition to the closing of the
merger agreement and contribution agreement that The Nasdaq National Market has
approved for listing the shares of Class A common stock to be issued in
connection with the transactions, subject only to official notice of issuance.


    NBCi has also applied to have the Class A common stock listed on the
European Association of Securities Dealers Automated Quotation system, refered
to as EASDAQ.


GOVERNMENTAL AND REGULATORY MATTERS (PAGE 70)

    U.S. antitrust laws prohibit NBC, Xoom.com and CNET from completing the
transactions until they have furnished information to the Antitrust Division of
the U.S. Department of Justice and the Federal Trade Commission and a required
waiting period has ended or been terminated early. NBC, Xoom.com and CNET
furnished the required information on July 2, 1999 and the waiting period
expired on August 1, 1999.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (PAGE 71)

    The obligation of Xoom.com to complete the merger of Xenon 3 with Xoom.com
pursuant to the merger agreement is conditioned upon the receipt by Xoom.com of
an opinion of its counsel that, for U.S. federal income tax purposes, the merger
will qualify as either or both of (A) a contribution of Xoom.com stock to NBCi
qualifying under Section 351 of the Internal Revenue Code, or (B) a tax-free
reorganization under Section 368 of the Internal Revenue Code. Provided the
merger so qualifies, Xoom.com stockholders will not recognize any gain or loss
upon the exchange of their Xoom.com common stock for NBCi Class A common stock.
In the event that Xoom.com is unable to obtain this opinion, Xoom.com is
permitted under the merger agreement to waive the receipt of the opinion as a
condition to its obligation to complete the merger. As of the date of this proxy
statement/prospectus, Xoom.com does not intend to waive the receipt of this
opinion as a condition to its obligation to complete the merger. In the event of
such a failure to obtain the opinion and a determination by Xoom.com to waive
receipt of an opinion as a condition to the completion of

                                       12
<PAGE>
the merger, Xoom.com will resolicit the votes of its stockholders to approve the
adoption of the merger agreement.
    TAX MATTERS ARE VERY COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER OF
XENON 3 WITH XOOM.COM WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD
CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF
THE MERGER TO YOU.
ANTICIPATED ACCOUNTING TREATMENT (PAGE 72)
    The transactions contemplated by the merger agreement and the contribution
agreement will be accounted for under the purchase method of accounting in
accordance with generally accepted accounting principles.

                     SUMMARY SELECTED FINANCIAL INFORMATION
              SELECTED HISTORICAL AND SELECTED UNAUDITED PRO FORMA
                       CONDENSED COMBINED FINANCIAL DATA
    The following selected historical financial data of Xoom.com, SNAP and the
NBC Multimedia Division, which consists of NBC.com, NBC-IN.com and VideoSeeker,
have been derived from their respective historical financial statements, and
should be read in conjunction with those financial statements and the related
notes. The selected unaudited pro forma condensed combined financial data of
Xoom.com, SNAP and the NBC Multimedia Division are derived from the unaudited
pro forma condensed combined financial information, which gives effect to the
transactions as a purchase, and should be read in conjunction with the unaudited
pro forma condensed combined financial information and related notes, which
begin on page 104 of this proxy statement/prospectus.
    For pro forma purposes, the historical statements of operations of Xoom.com,
SNAP and the NBC Multimedia Division for the year ended December 31, 1998 and
the six months ended June 30, 1999 have been combined to give effect to the
transactions as if they had occurred on January 1, 1998 and January 1, 1999,
respectively.
    The unaudited pro forma condensed combined balance sheet data assumes that
the transactions took place as of June 30, 1999 and combine the historical
balance sheets of Xoom.com, SNAP and the NBC Multimedia Division and other
purchase adjustments at that date.
    The final purchase price allocation will be calculated based on NBC
Multimedia's and SNAP's balance sheets and SNAP's stock options outstanding at
the date the transaction is consummated.
    The unaudited pro forma condensed combined information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have occurred if the transaction had
been consummated at the dates indicated, nor is it necessarily indicative of
future operating results or financial condition of NBCi.

- ------------------------
(1) Historical book value per share is computed by dividing stockholders' equity
    less goodwill and other intangible assets by the number of shares of common
    stock or units outstanding at the end of each period. Because the NBC
    Multimedia Division consists of operating units, and not subsidiaries, of
    NBC, net loss per share information is not meaningful.
(2) The pro forma condensed combined book value per share is computed by
    dividing pro forma stockholders' equity less goodwill and other intangible
    assets, including the effect of pro forma adjustments, by the pro forma
    number of shares of NBCi common stock which would have been outstanding had
    the transactions been consummated as of June 30, 1999.
(3) The SNAP equivalent pro forma condensed combined per share amounts are
    calculated by multiplying the pro forma condensed combined book value per
    share amounts by the exchange ratio of 1.2853 of a share of Xoom.com common
    stock for each unit of SNAP. Because the NBC Multimedia Division consists of
    operating units, and not subsidiaries, of NBC, equivalent pro forma
    condensed combined book value per share information is not meaningful.

    IN ADDITION TO THE OTHER INFORMATION INCLUDED IN THIS PROXY
STATEMENT/PROSPECTUS, YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS BEFORE
DECIDING WHETHER TO VOTE FOR THE TRANSACTIONS. ALL OF THESE RISKS COULD IMPAIR
NBCI'S BUSINESS, OPERATING RESULTS OR FINANCIAL CONDITION. IN EVALUATING THE
RISKS OF INVESTING IN NBCI, YOU SHOULD ALSO EVALUATE THE OTHER INFORMATION SET
FORTH IN THIS PROXY STATEMENT/PROSPECTUS, INCLUDING THE FINANCIAL STATEMENTS.

RISKS RELATED TO THE TRANSACTIONS AND TO NBCI'S BUSINESS

    THE FAILURE OF NBCI TO SUCCESSFULLY INTEGRATE THE OPERATIONS OF XOOM.COM,
     SNAP AND THE NBC CONTRIBUTED INTERNET BUSINESSES COULD HAVE A MATERIAL
     ADVERSE EFFECT ON ITS OPERATIONS

    The inability of NBCi's management to integrate successfully the operations
of SNAP and Xoom.com and the NBC contributed Internet businesses could have a
material adverse effect upon the business, operating results and financial
condition of NBCi. In addition, the benefits of the transactions may not be
realized and NBCi's stock price could be adversely affected. The anticipated
benefits of the transactions will depend substantially on whether Xoom.com, SNAP
and the NBC contributed Internet businesses can be integrated by NBCi in an
efficient and effective manner. NBCi can provide no assurance that this will
occur. The combination of the NBCi properties will require, among other things,
the technological integration of the Xoom.com, Snap.com, NBC.com, NBC-IN.com and
VideoSeeker.com Web sites and the coordination of the sales, marketing and
research and development efforts of Xoom.com, SNAP and the NBC contributed
Internet businesses.

    Some of the factors contributing to the risks attendant to integration faced
by NBCi are:

    - difficulties and expenses of integrating operations, technology and
      personnel into NBCi's operations while preserving the goodwill of the NBCi
      businesses;

    - the additional financial resources that may be needed to fund the
      operations of NBCi;

    - the potential disruption caused to the businesses of Xoom.com, SNAP and
      the NBC contributed Internet businesses by the need to dedicate management
      and other resources to completing the transactions;

    - the difficulty of creating and maintaining uniform standards, controls,
      procedures and policies;

    - the ability of NBCi's management to manage the substantial expansion of
      NBCi's employee base and the integration of teams that have not previously
      worked together while dealing with the potential loss of any key employees
      of Xoom.com, SNAP and the NBC contributed Internet businesses;

    - the impairment of relationships with employees and customers as a result
      of changes in management; and

    - the different geographic locations of the principal operations of each of
      Xoom.com, SNAP and the NBC contributed Internet businesses.

    NBCi cannot assure you that NBCi will be able to integrate the NBCi
businesses smoothly or successfully. The integration of operations following the
closing of the transactions will require the dedication of management resources,
which may distract attention from the day-to-day operations of NBCi.

    NBCI CANNOT ASSURE YOU THAT IT WILL BE PROFITABLE BECAUSE IT HAS NO
     OPERATING HISTORY AND THE COMPANIES AND PROPERTIES COMPRISING NBCI HAVE A
     LIMITED OPERATING HISTORY AND A HISTORY OF LOSSES

    NBCi was incorporated in May 1999 and has no operating history. Xoom.com was
founded in April 1996 and has a limited operating history. SNAP began operations
in December 1996 and the Snap.com Web site was launched by CNET in September
1997. SNAP was spun-off from CNET as an

                                       18
<PAGE>
independent entity owned by CNET and NBC in June 1998. NBC.com, NBC-IN.com and
VideoSeeker.com began operations in August 1995, October 1997, and May 1998,
respectively. NBC launched CNBC.com in June 1999. In addition, Xoom.com, SNAP
and the NBC contributed Internet businesses have not achieved positive annual
operating cashflows and NBCi expects to incur net losses for the foreseeable
future.

    Because of the limited operating histories of NBCi's businesses and the
uncertain nature of the rapidly changing markets NBCi will serve, future results
of operations cannot be predicted. Moreover, it is difficult for NBCi to plan or
anticipate NBCi's revenue potential and operating expenses based on the limited
historical financial data of the NBCi businesses.

    NBCi currently expects that its operating expenses will continue to increase
significantly as NBCi expands its sales and marketing operations, continues to
develop and extend the SNAP and other NBCi brands, funds greater levels of
product development, develops and commercializes additional media properties,
and acquires complementary businesses and technologies. Accordingly, NBCi will
need to increase revenues to be profitable. As a result, NBCi may experience
significant losses on a quarterly and annual basis. If NBCi's actual revenue is
lower than predicted, it may be unable to adjust its operating expenses
accordingly. If revenues do not grow as expected or increases in expenses are
not in line with forecasts, there could be a material adverse effect on NBCi's
business, results of operations and financial condition. If NBCi's operating
results in any period fall below the expectations of securities analysts and
investors, the market price of NBCi's shares would likely decline.

    NBCI AND THE NBCI BUSINESSES WILL BE SUBJECT TO ALL OF THE RISKS AND
     DIFFICULTIES FREQUENTLY ENCOUNTERED BY EARLY STAGE COMPANIES

    The prospects of the NBCi businesses are subject to all of the risks and
difficulties frequently encountered by early stage companies in new and rapidly
evolving markets, particularly those involved in the Internet and in e-commerce.
These risks include the following uncertainties and potential adverse
developments:

    - the uncertainty of the level of use of the Internet and online services
      and the acceptance of the Internet and other online services and products
      such as those NBCi will offer;

    - the lack of success of NBCi's proposed business model on the Internet;

    - NBCi's failure to continue to develop and extend the SNAP and other NBCi
      brands;

    - NBCi's inability to obtain needed financing;

    - higher than anticipated marketing costs that NBCi will need to incur in
      order to maintain and enhance SNAP and the other NBCi brands;

    - NBCi's inability to generate significant e-commerce revenue or premium
      service revenue from its members;

    - NBCi's inability to maintain and increase levels of traffic and membership
      on the NBCi Web sites or to manage rapidly expanding operations
      effectively;

    - the emergence of new services offered by NBCi's competitors that affect
      the level of traffic on the NBCi Web sites and NBCi's ability to expand
      its membership base;

    - NBCi's ability to predict demand for products and services it offers and
      to optimize inventory levels accordingly;

    - NBCi's inability to meet minimum guaranteed impressions under advertising
      agreements;

    - NBCi's failure to adapt to the mix of types of advertising NBCi will sell
      and developments relating to advertising on the Web;

    - NBCi's failure to anticipate and adapt to a developing Internet market and
      increased competition;

                                       19
<PAGE>
    - NBCi's inability to upgrade, develop and deploy its network, systems and
      infrastructure and attract new personnel in a timely and effective manner;
      and

    - the failure of NBCi's server and networking systems to handle traffic on
      NBCi's Web sites efficiently.

    IF NBCI DOES NOT SUCCESSFULLY INTEGRATE THE WEB SITES OF XOOM.COM, NBC.COM,
     NBC-IN.COM AND VIDEOSEEKER.COM INTO THE SNAP.COM WEB SITE OR IF USERS DO
     NOT ACCEPT THE INTEGRATED SNAP.COM WEB SITE NBCI'S OPERATIONS COULD BE
     ADVERSELY AFFECTED

    NBCi believes that combining the content, promotion, brands and technologies
of the NBCi Internet properties is a critical aspect of NBCi's efforts to
attract and expand its Internet audience and to differentiate NBCi from its
competitors. While NBCi intends to integrate the Xoom.com, NBC.com, NBC-IN.com
and VideoSeeker.com Web sites with the Snap.com Web site as soon as practicable
after the closing of the transactions, there can be no assurance that the
integrated service can be successfully developed and launched in this time
frame. In addition, NBCi's Web sites may not have all of the functionality and
services currently planned. If consumers do not perceive the content and
experience of NBCi's Web sites to be of high quality, or if NBCi introduces new
Internet sites or enters into new business ventures that are not favorably
received by users, NBCi will be unsuccessful in expanding its Internet audience.
NBCi can provide no assurances that it will be able to successfully integrate
the Xoom.com, NBC.com, NBC-IN.com and VideoSeeker.com Web sites with the
Snap.com Web site on a timely basis, or at all.

    NBCI ANTICIPATES THAT BUSINESS WILL FLUCTUATE FROM ONE PERIOD TO THE NEXT
     DUE TO ITS INITIAL RELIANCE ON SHORT-TERM ADVERTISING AGREEMENTS AND
     SEASONAL FLUCTUATIONS, WHICH COULD HARM NBCI'S RESULTS OF OPERATIONS

    Initially, a substantial portion of NBCi's net revenue is expected to be
from short-term advertising contracts, usually one to two months in length. That
means NBCi's quarterly net revenue will be a function of the contracts it enters
into within the quarter and its ability to adjust spending in light of any net
revenue shortfalls. As a result, the cancellation of even a small number of
advertising contracts could significantly affect NBCi's operating results.
NBCi's operating expenses are likely to increase significantly over the near
term. To the extent that NBCi's expenses increase but its revenues do not, its
business, operating results and financial condition may be materially and
adversely affected.

    Advertising revenue is also linked to the level of traffic on NBCi's Web
sites, so if traffic is less than the level expected by NBCi's advertising
customers, revenue from this source could be affected. NBCi will have some
advertising contracts that include a guaranteed minimum number of impressions on
NBCi's Web sites. Reduced traffic on NBCi's Web sites would cause NBCi to fall
short in meeting these minimum requirements and, as a result, NBCi may give
credits to its advertisers and reduce advertising rates, which would lead to a
reduction in NBCi's revenue from advertising.

    Advertising revenues are also subject to seasonal fluctuations.
Historically, advertisers spend less in the first and third calendar quarters
and user traffic on online media properties has been lower during the summer and
during year-end vacation and holiday periods. As a result, NBCi's results of
operations can be expected to fluctuate throughout the year, which may have a
material adverse effect on NBCi's business and financial condition.

    NBCI'S FAILURE TO ATTRACT ADVERTISING REVENUE IN QUANTITIES AND AT RATES
     THAT ARE SATISFACTORY TO NBCI COULD HARM ITS BUSINESS, RESULTS OF
     OPERATIONS AND FINANCIAL CONDITION

    NBCi expects to derive a significant portion of NBCi's net revenue from the
sale of advertisements, including banners, buttons, windows and text links.

                                       20
<PAGE>
    It is uncertain whether Web advertising will continue to grow at a rate that
will support expansion in NBCi's revenue. The Internet as a marketing and
advertising medium has not been available for a sufficient period of time to
gauge accurately its effectiveness as compared with traditional media. Many of
NBCi's suppliers and advertisers have only limited experience with the Web as a
marketing and advertising medium.

    The ability to generate significant advertising revenues will depend upon:

    - the development of a large base of users of services possessing
      demographic characteristics attractive to advertisers;

    - the ability to continue to develop and update effective advertising
      delivery and measurement systems; and

    - advertising rates.

    No standards have yet been widely accepted for the measurement of the
effectiveness of Web-based advertising. Advertisers may determine that banner
advertising, which will comprise a substantial portion of NBCi's revenues, is
not an effective advertising medium. If other forms of Web-based advertising
prove more popular than banner advertisements, NBCi may not be able to change
its operations to take advantage of such forms. Advertising filter software
programs are available that limit or remove advertising from an Internet user's
desktop. Such software, if generally adopted by users, may have a materially
adverse effect upon the viability of advertising on the Internet. NBCi's
advertising customers may not accept the internal and third-party measurements
of impressions received by advertisements on NBCi online media properties and
such measurements may contain errors. NBCi will rely primarily on NBCi's
internal advertising sales force for domestic advertising sales, which involves
additional risks and uncertainties, including risks associated with the
recruitment, retention, management, training and motivation of sales personnel.
As a result of these factors, NBCi may not be able to sustain or increase
advertising sales levels. Failure to do so may have a material adverse effect on
NBCi's business, operating results and financial position.

    INCREASED COMPETITION MAY EXERT DOWNWARD PRICING PRESSURE ON ADVERTISING
     CONTRACTS

    NBCi will compete for a fixed amount of money available for advertising and
promotions. NBCi will compete with online services as well as traditional
offline media such as television, radio, print and outdoor advertising for a
share of advertisers' total advertising budgets. Industry sources indicate that
the number of companies selling Web-based advertising and the available
inventory of online advertising space has recently increased substantially.
Advertisers have not yet devoted a significant portion of their advertising
budgets to Web-based advertising and may not find such advertising to be
effective for promoting their products and services relative to traditional
print and broadcast media. In 1998, advertising on the Web represented
approximately 1.2% of overall advertising spending in the United States
according to industry sources. Accordingly, NBCi may face increased pricing
pressure for the sale of advertisements, which could reduce its advertising
revenues. In addition, NBCi's sales may be adversely affected to the extent that
its competitors offer superior advertising services that better target users or
provide better reporting of advertising results.

    BECAUSE NBC WILL HAVE SIGNIFICANT INFLUENCE OVER THE MANAGEMENT AND STRATEGY
     OF NBCI, THE ABILITY OF THE EXISTING STOCKHOLDERS OF XOOM.COM TO DETERMINE
     THE OUTCOME OF MATTERS WILL BE REDUCED

    Upon the closing of the transactions, NBC and its affiliates are expected to
own approximately 47.3% of the outstanding common stock of NBCi. If the
convertible notes are converted, this ownership interest could increase up to
approximately 52.6%, although such conversion cannot occur for a period of one
year following closing. Even before the convertible notes are converted,
however, CNET has agreed to vote its shares of Class A common stock in the same
manner as NBC with respect to change in control transactions involving NBCi,
enabling NBC to determine the outcome of such

                                       21
<PAGE>
vote. In addition, NBC and its affiliates have rights to maintain their
percentage ownership in the event of dilutive issuances of stock by NBCi. As a
result, NBC may be able to exercise effective control in the future over many
matters requiring approval by NBCi's stockholders, including amending NBCi's
restated certificate of incorporation and amended and restated bylaws, the
issuance of additional shares of Class B common stock of NBCi or the adoption of
a stockholders rights plan.

    In addition, NBC and its affiliates have the right to elect six of the 13
members of the NBCi board of directors, and will retain that right so long as
they own 20% of the outstanding shares of common stock of NBCi. Following
conversion of the convertible notes, for so long as NBC and its affiliates own
35% or more of the outstanding shares of NBCi common stock, NBC and its
affiliates will have the right to elect seven of the 13 members of the NBCi
board of directors. As long as the NBC directors do not constitute a majority of
the NBCi board of directors, several significant corporate actions by NBCi will
require the approval of NBC's directors, including a change in control of NBCi
or its significant subsidiaries and significant sales of assets or securities by
NBCi. For as long as there are any Class B directors, those directors will have
the exclusive ability to remove the chief executive officer and to appoint the
chief financial officer and the general counsel of NBCi. In addition, Robert C.
Wright, the president and chief executive officer of NBC, will serve as the
chairman of the board of NBCi. Many of these rights will be embodied in the
restated certificate of incorporation of NBCi, and as a result any amendment
will require a vote of the stockholders of NBCi. See "Description of Capital
Stock."

    Because of these rights, NBC will have the ability to exert significant
influence over the management and strategy of NBCi. While NBC's directors are
obligated by Delaware law to act in the best interests of NBCi and its
stockholders, NBC's views concerning the management and strategy of NBCi may be
different from the strategy taken in the past by the board of directors and
management of Xoom.com.

    NBC WILL BE ABLE TO ENGAGE FREELY IN MANY ACTIVITIES WHICH MAY BE
     COMPETITIVE WITH THE BUSINESS OF NBCI

    Under the brand integration and license agreement, NBC is obligated not to
license competitors of NBCi to co-brand the portal community and e-commerce
services of such competitors with specified NBC marks, and NBC may not operate a
general portal service, a broad-based community service or a broad-based
e-commerce service other than through NBCi. However, apart from the restrictions
in the brand integration and the license agreement, the restated certificate of
incorporation of NBCi provides that NBC has the right to engage in, and has no
duty to refrain from engaging in, the same or similar activities or lines of
business as NBCi, to do business with potential or actual customers and
suppliers of NBCi and to employ any employee of NBCi. In the event that NBC
learns of a potential corporate opportunity of both NBC and NBCi, NBC has no
duty to communicate or present the opportunity to NBCi management. NBC will have
no liability to NBCi or its stockholders for breach of any fiduciary duty which
may be applicable to NBC as a major stockholder of NBCi for acquiring or
pursuing any corporate opportunity for itself, directing the opportunity to
another person or company, or failing to communicate information about the
opportunity to NBCi.

    Moreover, the certificate of incorporation of NBCi provides that persons who
are directors or officers of NBCi and also of NBC are deemed to have fully
satisfied their fiduciary duties to NBCi with respect to corporate opportunities
of NBC and NBCi if they act consistently with the policy regarding corporate
opportunities set forth in the certificate of incorporation of NBCi. In
particular, a corporate opportunity offered to any person who is a director, but
not an officer, of NBCi and who is also a director or officer of NBC belongs to
NBCi only if offered in writing to such person solely in his or her capacity as
a director of NBCi, and otherwise belongs to NBC.

    These provisions are effective for so long as NBC owns at least 20% of the
common stock of NBCi and at least one person who is a director or officer of
NBCi is also a director or officer of NBC. In addition, amendment of these
provisions of the restated certificate of incorporation of NBCi in a

                                       22
<PAGE>
manner adverse to NBC's interests will require the approval of at least 80% of
the outstanding common stock of NBCi.

    While as NBCi's principal stockholder NBC has a significant financial
interest in NBCi's success, NBC also has the objective of maximizing value for
its parent company, GE, and the stockholders of GE. There may be circumstances
under which NBC's corporate objectives conflict with the operations or strategy
of NBCi, and, except as may otherwise be required by law, NBC has no obligation
to act in a manner beneficial to NBCi in the event of such a conflict. For
example, NBC has entered into a distribution and marketing agreement with
ValueVision International, Inc. with respect to its home shopping and
transactional television service, and an affiliate of NBC is a principal
shareholder of ValueVision. NBC is also the parent company of the CNBC cable
channel and will own 90% of CNBC.com LLC. Moreover, NBC distributes its owned
and licensed television programming and other content over a wide array of media
in varied formats, including videostreaming and other methods of distribution of
video content via the Internet, and the transactions will not limit its ability
to continue to do so or to develop new methods of distribution or delivery or
forms of content independently from NBCi. In addition, the value of NBC-IN.com
will be dependent on NBCi's ability to negotiate content and distribution
relationships with NBC's affiliated television stations, including the 13
stations owned by NBC. Although NBC is obligated to comply with the terms of the
brand integration and license agreement, there can be no assurance that NBC will
not engage in activities which are competitive with or otherwise negatively
affect the business of NBCi. Any such action by NBC may have a material adverse
effect on NBCi's business, operating results and financial condition.

    NBC'S RELATIONSHIPS WITH ITS STRATEGIC PARTNERS WILL LIMIT NBCI'S ABILITY TO
     ENTER INTO STRATEGIC RELATIONSHIPS AND TO PROVIDE NEWS, INCLUDING SPORTS
     AND BUSINESS NEWS, ON ITS WEB SITES

    NBC's relationships with its existing strategic partners and NBCi's future
relationships with partners may limit NBCi's ability to enter into other
strategic relationships or provide services that NBCi might otherwise offer on
its Web sites. For example, NBC has a relationship with Microsoft which limits
in significant respects the ability of NBC and its affiliates to provide news,
including sports and business news, on any Web site other than MSNBC.com. In
addition, the ability of NBC and its affiliates to deliver business news video
on an interactive basis via the Internet is restricted by the terms of NBC's
joint ventures with Microsoft and Dow Jones. NBCi may enter into similar or
other non-compete arrangements with strategic partners that may limit its
ability to engage in or provide some activities or services.

    EXISTING USERS, MEMBERS AND CUSTOMERS OF XOOM.COM, SNAP AND THE NBC
     CONTRIBUTED INTERNET BUSINESSES MAY NOT CONTINUE TO USE NBCI'S PRODUCTS AND
     SERVICES

    There can be no assurance that the present and potential customers of SNAP,
Xoom.com and the NBC Internet businesses will continue their current usage and
buying patterns without regard to the proposed transactions. For example, there
can be no assurance that large media companies and other competitors of NBC will
elect to advertise or provide content to the integrated Snap.com Web site. Any
significant delay or reduction in sales or orders could have an adverse effect
on the near-term business and results of operations of NBCi. In addition, there
can be no assurance that the integration of NBCi's Internet properties with the
Snap.com Web site will not confuse or cause a decline in loyalty among users or
customers of the Xoom.com, Snap.com and the NBC Internet property Web sites.

    THE COSTS OF THE TRANSACTIONS AND THE COSTS OF INTEGRATING NBCI'S PROPERTIES
     ARE SUBSTANTIAL AND WILL MAKE IT MORE DIFFICULT FOR NBCI TO ACHIEVE
     PROFITABILITY

    NBCi will incur substantial costs in connection with the transactions which
may make it more difficult to achieve profitability in the future. NBCi
estimates that it will incur costs of approximately $21.9 million associated
with the transactions. These costs will consist of transaction fees for
investment bankers, attorneys, accountants and other related costs incurred by
NBC, Xoom.com, SNAP and CNET.

                                       23
<PAGE>
These nonrecurring transaction costs will be recorded as goodwill upon
consummation of the transactions. NBCi expects to incur additional nonrecurring
restructuring charges, currently estimated to be approximately $1.6 million.
There can be no assurance that NBCi will not incur additional charges in excess
of these amounts to reflect costs associated with the transactions, including
the costs of integrating the NBCi properties.

    NBCI IS IN A HIGHLY COMPETITIVE INDUSTRY AND SOME OF ITS COMPETITORS MAY BE
     MORE SUCCESSFUL IN ATTRACTING AND RETAINING CUSTOMERS

    The market for Internet products and services is highly competitive. There
are no substantial barriers to entry in these markets, except that the ability
to secure financial resources necessary to promote brand awarness is
increasingly becoming a barrier to entry in the market in which NBCi intends to
compete. NBCi expects that competition will continue to intensify. Negative
competitive developments could have a material adverse effect on NBCi's business
and the trading price of its Class A common stock. In addition, even if the
integration of NBCi Internet properties is successful, NBCi's competitors may
still have superior or more attractive product offerings.

    NBCi will compete with many other providers of online navigation,
information and community services, such as Yahoo! (including GeoCities and
Broadcast.com), America Online (including AOL.com, Netcenter and ICQ),
AltaVista, Excite@Home, Disney (including the GO Network, which is jointly
operated with Infoseek), Lycos (including HotBot and Tripod) and Microsoft
Corporation (including msn.com).

    The NBCi businesses will compete directly with a great number of other
Internet sites and other media companies across a wide range of different online
services with advantages in technical expertise, brand recognition and other
factors, including:

    - metasearch services and software applications that allow a user to search
      the databases of several directories and catalogs simultaneously;

    - database vendors that offer information search and retrieval capabilities
      with their core database products;

    - Web-based e-mail and instant messaging services either on a stand alone
      basis or integrated into other products and media properties;

    - online merchant hosting services and the entry of an increasing number of
      companies selling goods and services on the Internet;

    - online content Web sites such as ESPN.com and ZDNet.com;

    - online local interactive content Web sites, such as Excite@Home's City
      Guides, Lycos City Guides, America Online's Digital City, Ticketmaster
      Online-CitySearch, Yahoo! Get Local and Microsoft Sidewalk;

    - online video broadcast services, such as CNN VideoSelect, RealNetworks and
      FoxNews;

    - online community Web sites, such as iVillage, Tripod, WhoWhere, GeoCities
      and theglobe.com; and

    - potential new entrants in any one or all of these areas, or new areas not
      considered.

    In order to effectively compete, NBCi may need to expend significant
internal engineering resources or acquire other technologies and companies to
provide such capabilities. Any of these acquisitions could be dilutive to NBCi's
stockholders.

    The amended carriage agreement limits CNET's ability to compete with SNAP to
provide a broad based information, navigation and content aggregation service.
These restrictions, however, will no

                                       24
<PAGE>
longer apply after May 9, 2000. As a result, CNET could become a competitor of
SNAP. This could have a material adverse effect on NBCi's business and the
trading price of its Class A common stock.

    ANY INCREASE IN COMPETITION IN THE E-COMMERCE MARKET COULD ADVERSELY AFFECT
     NBCI'S ABILITY TO MAINTAIN OR IMPROVE ITS POSITION IN THE MARKET RELATIVE
     TO THAT OF NBCI'S COMPETITORS

    NBCi expects intense competition in the e-commerce market from an ever
increasing number of companies selling goods and services over the Internet,
particularly goods and services that relate to the use of computers. These
competitors include: traditional computer retailers including CompUSA; various
mail-order retailers; Internet-focused retailers including Amazon.com, Egghead's
Egghead.com, software.net and New England Circuit Sales' NECX Direct;
manufacturers that sell directly over the Internet including IBM, Dell Computer,
Gateway and Apple Computer; and many software companies. In addition, a number
of online service providers including America Online and the Microsoft Network
offer computer products directly or in partnership with other retailers.
Finally, new competitors may also emerge.

    Increased competition from these and other sources could require NBCi to
respond to competitive pressures by establishing pricing, marketing and other
programs or seeking out additional strategic alliances or acquisitions that may
be less favorable to NBCi than it could otherwise establish or obtain, and thus
could have a material adverse effect on NBCi's business, prospects, financial
condition and results of operations.

    MARKET CONSOLIDATION HAS CREATED AND CONTINUES TO CREATE COMPANIES THAT ARE
     LARGER AND HAVE GREATER RESOURCES THAN NBCI

    In the recent past, there have been a number of significant acquisitions and
strategic plans announced among and between NBCi's anticipated competitors,
including:

    - Disney's acquiring the remaining interest in Infoseek not already owned by
      Disney;

    - AOL's acquiring Netscape;

    - @Home Network, a provider of high-speed Internet access serving the cable
      television infrastructure and whose largest stockholder is AT&T, acquiring
      Excite;

    - Yahoo!'s acquiring both GeoCities and Broadcast.com; and

    - CMGI's acquiring 83% of AltaVista.

    The effect of these completed and pending acquisitions and strategic plans
on NBCi cannot be predicted with accuracy, but some of these competitors are
aligned with companies that are larger or more well established than NBCi. In
addition, these competitors include television broadcasters with access to
unique content and substantial marketing resources that could be used to assist
NBCi's competitors. As a result, these competitors may have access to greater
financial, marketing and technical resources than NBCi.

    RECENT ALLIANCES HAVE RESULTED IN COMPETITORS OFFERING A BROADER VARIETY OF
     INTERNET RELATED SERVICES THROUGH MORE INTEGRATED WEB SITES AND THE USE OF
     PROMINENT SEARCH BUTTONS TO DIRECT TRAFFIC, WHICH MAY MAKE IT MORE
     DIFFICULT FOR INTERNET USERS TO FIND AND USE NBCI'S PRODUCTS AND MEDIA
     PROPERTIES

    As discussed above, recent acquisitions and alliances will result in greater
competition as more users of the Internet consolidate on fewer services that
incorporate search and retrieval features. In addition, providers of software
and other Internet products and services are incorporating search and retrieval
features into their offerings. For example, Web browsers offered by Microsoft
and by America Online's Netscape increasingly incorporate prominent search
buttons that direct search traffic to competing services. These features could
make it more difficult for Internet users to find and use NBCi's products and
services.

                                       25
<PAGE>
    In the future, Netscape, Microsoft and other browser suppliers may also more
tightly integrate products and services similar to SNAP's into their browsers or
their browsers' pre-set home pages. Microsoft recently announced that it will
feature and promote Internet search services provided by Alta Vista and signed a
long term partnership with LookSmart to provide directory services in the
Microsoft Network and other Microsoft online properties. Such search services
may be tightly integrated into future versions of the Microsoft operating
system, the Internet Explorer browser, and other software applications, and
Microsoft may promote such services within the Microsoft Network or through
other Microsoft affiliated end-user services such as WebTV Networks. Each of
these situations creates a potential competitive advantage over NBCi because
Internet navigational offerings of competitors are more conveniently accessed by
users.

    IF NBCI'S INVESTMENT OF RESOURCES IN PROMOTING SNAP AND THE OTHER NBCI
     BRANDS IS NOT SUCCESSFUL, THE RESULTS OF NBCI'S OPERATIONS COULD BE
     ADVERSELY AFFECTED

    As the number of Internet sites grows, brand recognition will play an
increasingly important role. Establishing and promoting SNAP and the other NBCi
brands in the face of pressures from NBCi's competitors will be critical to
further developing its member and user base as well as various strategic and
commercial relationships. NBCi will need to continue to devote substantial
financial and other resources to maintain the distinctiveness of SNAP and other
NBCi brands to members, advertisers and commerce partners through:

    - Web advertising and marketing;

    - traditional media advertising campaigns in television, print, radio and
      billboards; and

    - providing a high quality user experience.

    For this purpose, NBCi has agreed to purchase at least $405 million of
promotional services from NBC over a four year period to promote SNAP and the
other NBCi brands as well as NBCi's products and services. The results of NBCi's
operations could be adversely affected if this investment of financial and other
resources in promoting NBCi's brands does not generate a corresponding increase
in net revenue, or if the expense of promoting SNAP and the other NBCi brands
becomes excessive.

    NBCI WILL BE SIGNIFICANTLY DEPENDENT UPON THE QUALITY OF THE NBC BRAND

    A deterioration in the quality or value of the NBC brand or the termination
of the brand integration and license agreement may have a material adverse
effect on the business, operating results and financial condition of NBCi.
Xoom.com, SNAP and NBC believe licensed use of the NBC brand is a critical
aspect of NBCi's efforts to retain, attract and expand its user and advertiser
base, both through the advertising and promotion NBCi will purchase on the NBC
television network as well as the inclusion of the NBC brand on the NBCi Web
sites. The television industry is characterized by a small number of
participants with significant financial resources and substantial experience in
a wide variety of media, and consequently is extremely competitive. The success
of each television network is often dependent upon its ability to deliver
programming that appeals to viewers. Television programming often requires
substantial lead time to develop and produce, and seasonal network schedules are
typically designed months before actually being aired. This limits a network's
flexibility to alter programming to respond to changes in viewers' tastes. The
relative ranking of television networks fluctuates continuously. Each network
conducts its own research and obtains research from third parties in order to
evaluate its appeal to a complex variety of demographic groups, and each network
uses this information to promote its television programming and negotiate
pricing with advertisers. While NBC has enjoyed significant success in broadcast
and cable television and expects to continue to devote its efforts to continuing
this success, NBCi cannot be assured that NBC television programming will
continue to appeal to viewers generally, or to the particular demographic groups
which are valued by advertisers. Consequently, NBCi cannot predict the extent to
which use of the NBC brand will have a positive effect on NBCi's ability to
attract users and advertisers. In addition, NBC may terminate the brand
integration and license agreement if, among other reasons, its percentage
ownership in NBCi declines to 5% or less, or if there is a change in control of
NBCi.

                                       26
<PAGE>
    THE USE OF A COMMUNITY PLATFORM IS UNPROVEN AND DEPENDS ON MAINTAINING AND
     EXPANDING NBCI'S MEMBERSHIP BASE; NBCI DOES NOT KNOW WHETHER THE NBCI'S
     COMMUNITY PLATFORM WILL BE VIABLE AND PROFITABLE

    A part of NBCi's business model relies on using Xoom.com's community
platform and membership base to generate revenues from different sources. To be
profitable, NBCi will need to provide goods and services that are attractive to
NBCi's members, advertisers and vendors. Xoom.com has previously relied on
member-generated content and the "grassroots" voluntary promotional efforts of
its members to develop and maintain Xoom.com's profile as a community site. A
decline in voluntary promotional activities by the members or member-generated
content could make the community services offered by NBCi less attractive.

    NBCi cannot be sure that Internet users will continue to be interested in
communities on the Web, or that direct e-mail marketing will prove to be a
profitable or effective method of selling goods and services.

    NBCI'S SUCCESS WILL DEPEND UPON THE GROWTH IN THE USE OF THE INTERNET FOR
     E-COMMERCE TRANSACTIONS

    The future success of NBCi also depends on the continued growth in the use
of the Internet and the Web for e-commerce transactions. Use of the Internet for
retail transactions is a recent development, and the continued demand and growth
of a market for services and products via the Internet is uncertain. The
Internet may ultimately prove not to be a viable commercial marketplace for a
number of reasons, including:

    - unwillingness of consumers to shift their purchasing from traditional
      retailers to online purchases;

    - lack of acceptable security for data and concern for privacy of personal
      information;

    - limitations on access and ease of use;

    - congestion leading to delayed or extended response times;

    - inadequate development of Web infrastructure to keep pace with increased
      levels of use; and

    - increased or excessive government regulation.

    Because of these factors, NBCi does not know whether the business model of
NBCi will ultimately be viable and profitable. It is also possible that, in the
future, some Internet access providers will act to block or limit the use of
e-mail for direct e-commerce solicitations, whether at their own initiative or
at the request of users. Members of NBCi may also choose not to receive NBCi's
e-mail offerings or may fail to respond to such offerings. If these blocking or
limiting programs become popular, there could be a material adverse effect upon
the viability of e-commerce on the Web and on NBCi's business, results of
operations and financial condition.

    ANY FAILURE OF NBCI'S NETWORK INFRASTRUCTURE COULD HAVE A MATERIAL ADVERSE
     EFFECT ON ITS RESULTS OF OPERATIONS

    NBCi's success depends upon the capacity, reliability and security of its
networking hardware and software infrastructure. Any failure in NBCi's
networking hardware and software infrastructure could significantly and
adversely impact the results of NBCi's operations.

    SNAP and Xoom.com have developed their systems for maintaining their Web
sites, processing transactions and managing orders internally. If, in the
future, NBCi cannot modify these systems to accommodate increased traffic and an
increased volume of transactions and orders, it could suffer slower response
time, problems with customer service and delays in reporting accurate financial
information.

                                       27
<PAGE>
    Xoom.com uses network servers that are housed separately by application at
Exodus Communications, Inc. in Santa Clara, California and Frontier Global
Center in Sunnyvale, California. SNAP uses network servers housed at CNET's
facility in San Francisco, California, but expects to relocate these servers to
the Frontier Global facility by October 1999. There is a risk that the backup
system for SNAP's servers constructed at the Frontier Global facility may fail
or be inadequate to effect the relocation without any disruption in Internet
access. The NBCi Web sites will be connected to the Internet via multiple links
on a 24 hour-a-day, seven days per week basis by Exodus and Frontier Global
Center. Exodus and Frontier Global Center will also provide and manage power and
environmentals for NBCi's networking and server equipment. NBCi will manage and
monitor its servers and network remotely from its headquarters in San Francisco,
California. NBCi will strive to rapidly develop and deploy high-quality tools
and features into its systems without interruption or degradation in service.

    Although agreements with hosting companies will give NBCi remedies for
service interruptions, NBCi cannot guarantee that:

    - NBCi will have uninterrupted access to the Internet;

    - NBCi's members and users will be able to reach its Web sites; or

    - communications via NBCi's Web sites will be secure.

    Any disruption in the Internet access provided by NBC's hosting companies,
or any interruption in the service that NBC's hosting companies receive from
other providers, or any failure of NBC's hosting companies to handle higher
volumes of Internet users to NBCi's Web sites could have a material adverse
effect on NBCi's business, results of operations and financial condition.

    Despite precautions taken by the NBCi businesses and by the companies that
will host NBCi's Web sites, its system will be susceptible to natural and
man-made disasters such as earthquakes, fires, floods, power loss and sabotage.
NBCi's systems also will be vulnerable to disruptions from computer viruses and
attempts by hackers to penetrate NBCi's network security.

    NBCi will be covered by insurance for loss of income from some of the events
listed above, but this insurance may not be adequate to cover all instances of
system failure. NBCi also will have insurance against loss of income due to
earthquakes, but the amount of such insurance may be insufficient, especially
given the frequency and magnitude of earthquakes in Northern California where
NBCi's primary facilities and servers will be located.

    Any of the events listed above could cause interference, delays, service
interruptions or suspensions and adversely affect NBCi's business and results of
operations.

    NBCi must continue to expand and adapt its system infrastructure to keep
pace with the increase in the number of members who use the free services it
expects to provide. Demands on infrastructure that exceed NBCi's current
forecasts could result in technical difficulties with its Web sites. Any system
failure that interferes with the access to NBCi's Web sites and the use of the
free services NBCi will provide could diminish the level of traffic on its Web
sites. Continuing or repeated system failures could impair NBCi's reputation and
the NBCi brand names and reduce NBCi's commerce and advertising revenue. At
present, NBCi does not know if it will be able to scale the systems to handle a
larger amount of traffic at higher transmission speeds. Expanding the network
infrastructure will require substantial financial, operational and management
resources following the consummation of the transactions, all of which could
affect the results of NBCi's operations.

    If, in the future, NBCi cannot modify these systems to accommodate increased
traffic and an increased volume of transactions and orders, NBCi could suffer
slower response times, problems with customer service and delays in reporting
accurate financial information. Any of these factors could significantly and
adversely impact the results of NBCi's operations.

    DIFFICULTIES NBCI MAY ENCOUNTER IN DEALING WITH ITS GROWTH AND EXPANSION
     COULD ADVERSELY AFFECT THE RESULTS OF NBCI'S OPERATIONS

    NBCi's strategy is to continue growing its membership and user base at a
rapid pace. This strategy is likely to place a significant strain on NBCi's
resources and, if this growth continues following the completion of the
transactions, NBCi will experience a significant strain on its resources because
of:

    - the need to manage relationships with various strategic partners,
      technology licensors, members, advertisers and other third parties;

    - difficulties in hiring and retaining skilled personnel necessary to
      support NBCi's businesses;

    - the need to train and manage a growing employee base; and

    - pressures for the continued development of NBCi's financial and
      information management systems.

    Difficulties NBCi may encounter in dealing successfully with the above risks
could adversely affect the results of NBCi's operations.

    THE SUCCESSFUL OPERATION OF NBCI'S BUSINESS DEPENDS UPON THE SUPPLY OF
     CRITICAL ELEMENTS FROM OTHER COMPANIES

    NBCi will depend substantially upon third parties for several critical
elements of its business in addition to infrastructure, including technology,
order fulfillment, content development and distribution activities.

    TECHNOLOGY:  NBCi will license technology and related databases from third
parties for some elements of NBCi's properties, including, among others,
technology underlying the delivery of stock quotes and current financial
information, chat services, street mapping, telephone listings and similar
services. NBCi expects to experience interruptions and delays in service and
availability for such elements, from time to time. Furthermore, NBCi will be
dependent on hardware suppliers for prompt delivery, installation and service of
servers and other equipment used to deliver its products and services. Any
errors, failures, or delays experienced in connection with these third-party
products and information services could negatively affect NBCi's relationship
with users and adversely affect its brands and its business, and could expose
NBCi to third party liability.

    ORDER FULFILLMENT:  NBCi will rely on other companies for critical aspects
of its business. For example, Banta Corporation is primarily responsible for
fulfilling orders for products and services sold via the Xoom.com Web site and
in response to direct e-mail marketing. If NBCi's relationship with Banta were
to terminate without sufficient advance notice, NBCi's operations would be
negatively affected, even if NBCi were able to quickly establish a relationship
with a comparable vendor to fulfill orders. The success of NBCi's specific
e-mail direct e-commerce campaigns depends on the timely supply of inventory by
the manufacturers and suppliers of the products NBCi will offer for sale to its
members. The failure of the suppliers on whom NBCi will depend would adversely
affect the results of NBCi's operations.

    CONTENT DEVELOPMENT: A key element of NBCi's strategy involves the
implementation of NBCi-branded media properties targeted for specific interest
areas, demographic groups and geographic areas. In these efforts, NBCi will rely
on content development and localization efforts of third parties. NBCi cannot
guarantee that the third parties will effectively implement these properties, or
that their efforts will result in significant revenue to NBCi. Any failure of
these parties to develop and maintain high-quality and successful media
properties also could hurt the NBCi brands.

    DISTRIBUTION RELATIONSHIPS:  In order to create traffic for its online
properties and make them more attractive to advertisers and consumers, NBCi
expects to have distribution agreements and informal

                                       29
<PAGE>
relationships with leading Web browser providers/portals such as America
Online's Netscape, operators of online networks and leading Web sites,
manufacturers of Internet devices and computer manufacturers. These distribution
arrangements typically are not exclusive, and may be terminated upon little or
no notice. Third parties that provide distribution typically charge fees or
otherwise impose additional conditions on the listing of NBCi's online
properties. Any failure to cost-effectively obtain distribution could have a
material adverse effect on NBCi's business, results of operations and financial
condition.

    PLANNED INTERNATIONAL OPERATIONS ARE SUBJECT TO RISKS THAT COULD HAVE A
     MATERIAL ADVERSE EFFECT ON NBCI'S RESULTS OF OPERATIONS

    NBCi plans to establish operations or form business partnerships in other
parts of the world. The businesses comprising NBCi have very limited experience
in international markets and may not be able to compete effectively in
international markets. The expansion of operations into additional international
markets will require substantial management attention and financial resources.
NBCi cannot be certain that its investment in establishing operations in other
countries will produce the desired levels of revenue. In addition, international
operations are subject to other inherent risks and problems, including:

    - the impact of recessions in economies outside the United States;

    - slower adoption by users of and advertisers on the Internet in foreign
      countries;

    - greater difficulty in collecting accounts receivable;

    - higher costs to develop new or specialized content;

    - widely varied and changing regulatory requirements;

    - difficulties and costs of staffing and managing foreign operations;

    - reduced protection for intellectual property rights in some countries;

    - political and economic instability;

    - continued acceptance of euro;

    - fluctuations in currency exchange rates; and

    - difficulty in maintaining effective communications due to distance and
      language and cultural barriers.

    Some or all of the above factors could have a material adverse effect on the
results of NBCi's operations.

    IMPOSITION OF NEW TAXES OR FEES BY FEDERAL, STATE OR FOREIGN GOVERNMENTS ON
     INTERNET TRANSACTIONS OR ON THE USE OF THE INTERNET AS A MEANS OF
     COMMUNICATION COULD ADVERSELY AFFECT NBCI

    Imposition of sales or other similar taxes on NBCi's sales of merchandise in
states or countries where it ships goods could have a material adverse effect on
its results of operations. Imposition of new taxes or fees by federal, state or
foreign governments on Internet transactions or on the use of the Internet as a
means of communication could also adversely affect NBCi.

                                       30
<PAGE>
    COMPETITION FOR QUALIFIED PERSONNEL IS INTENSE, AND THE LOSS OF KEY
     PERSONNEL AND NBCI'S INABILITY TO ATTRACT AND RETAIN ADDITIONAL QUALIFIED
     PERSONNEL COULD HAVE A MATERIAL ADVERSE EFFECT ON NBCI'S RESULTS OF
     OPERATIONS

    NBCi's success depends to a significant degree upon the contributions of its
executive management team, most of whom have not previously worked together, as
well as technical, marketing and sales personnel of NBCi and the NBCi
businesses. Due to the integration of the operations of the NBCi businesses,
NBCi's employees may have different job responsibilities and may be required to
work with new people. Accordingly, NBCi may experience loss of key management
and other personnel due to the change in job responsibilities and work
environment. NBCi's employees may voluntarily terminate their employment with
NBCi at any time. NBCi's success also depends upon its ability to attract and
retain additional highly qualified management, technical, sales and marketing
and customer support personnel. Locating personnel with the combination of
skills and attributes required to carry out NBCi's strategy is often a lengthy
process. In addition, competition for qualified employees is intense,
specifically in the areas of Web site development, design and integration. The
loss of key personnel, or the inability to attract and retain additional,
qualified personnel, could have a material adverse effect on NBCi's results of
operations.

    TO BE SUCCESSFUL IN THE CONTINUALLY EVOLVING MARKET FOR ONLINE SERVICES,
     NBCI MUST CONTINUE TO ENHANCE ITS PROPERTIES AND DEVELOP NEW ONES

    Rapid technological change, changing customer needs, frequent new product
and service introductions and evolving industry standards characterize the
Internet market. These market characteristics could render NBCi's existing
services, technology and systems obsolete. NBCi must continually improve the
performance features and reliability of its services to respond to evolving
market demands and competition. NBCi's business, operating results and financial
condition would be materially adversely affected if it is unable to respond in a
cost-effective and timely manner to changing market conditions or customer
requirements.

    To remain competitive, NBCi must continue to enhance and improve the
functionality, features and content of the NBCi Web sites. NBCi may not be able
to successfully maintain competitive user response times or implement new
features and functions, as these changes will likely involve the development of
increasingly complex technologies. Personalized information services, such as
NBCi's Web-based e-mail services, message boards, stock portfolios and NBCi's
community features, require significantly greater expenses than NBCi's general
services. NBCi cannot guarantee that these higher expenses will be offset by
additional revenues.

    A key element of NBCi's business strategy is the development and
introduction of new NBCi-branded online properties targeted for specific user
groups with particular demographic characteristics and geographic concentration.
NBCi may not be successful in developing, introducing and marketing such
products or media properties and such properties may not achieve market
acceptance, enhance its brand name recognition, or increase user traffic.
Furthermore, enhancements of or improvements to NBCi's Web sites or new media
properties may contain undetected errors that require significant design
modifications, resulting in a loss of customer confidence and user support and a
decrease in the value of its brand name. If NBCi fails to effectively develop
and introduce new properties, or those properties fail to achieve market
acceptance, NBCi's business, results of operations and financial condition could
be adversely affected.

    THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT MAY OCCUR WITHOUT THE
     TRANSACTIONS CONTEMPLATED BY THE CONTRIBUTION AGREEMENT OCCURRING, AND AS A
     RESULT, MANY OF THE PERCEIVED BENEFITS ARISING FROM A RELATIONSHIP WITH NBC
     AND ITS CONTRIBUTED INTERNET BUSINESSES WOULD NOT OCCUR


    The closing of the contribution agreement is not a condition to the closing
of the merger agreement. If the transactions contemplated by the contribution
agreement do not happen, many of the perceived benefits of the Xoom.com merger
with Xenon 3 would not occur and the resulting company may be less competitive
and consequently less attractive to investors. Specifically, the surviving
entity:

    - would consist of Xoom.com plus an 81% non-controlling interest in SNAP,
      which may be reduced to 40% and thereafter down to 25% if NBC Multimedia
      were to exercise its two options to purchase additional ownership
      interests in SNAP;

    - would have significant influence over the operating and financing
      decisions of SNAP, but would not control SNAP because of the governance
      rights shared by the surviving entity and NBC;

    - would not be affiliated with NBC, other than through their shared
      ownership of SNAP;

    - would not enter into an advertising agreement with NBC;

    - would not have access to NBC's name, trademarks or the NBC contributed
      Internet properties; and

    - would not have the right to use "NBC" in its name.


    In addition, the Class B Directors, including John F. Welch, Jr., would not
serve as directors nor would Robert C. Wright become the chairman of the board
of the surviving entity. Also, as discussed beginning on page 90, if the
stockholders of Xoom.com fail to approve the adoption of the contribution
agreement after a third party has made a bona fide proposal to Xoom.com or its
stockholders to engage in an acquisition transaction, NBC could exercise its
option to purchase approximately 19.9% of the common stock of Xoom.com, which
would dilute the ownership interests of Xoom.com's current stockholders.



    Xoom.com cannot estimate accurately the risk that the transactions
contemplated by the merger agreement will occur without the transactions
contemplated by the contribution agreement occurring, as it cannot control or
predict, as of the date of this proxy statement/prospectus, whether the
stockholders of Xoom.com will approve either or both of the transactions. A more
detailed discussion of the effect on the surviving entity if the transactions
contemplated by the contribution agreement do not occur can be found on page
124.


    STOCKHOLDERS OF XOOM.COM WILL BE ENTITLED TO RECEIVE ONE SHARE OF NBCI
     COMMON STOCK DESPITE CHANGES IN MARKET VALUE OF XOOM.COM COMMON STOCK

    Each share of Xoom.com common stock will be exchanged for one share of NBCi
common stock upon completion of the Xoom.com merger. This exchange ratio will
not be adjusted for changes in the market price of Xoom.com common stock.
Accordingly, an increase or decrease in the market value of Xoom.com's common
stock will have no effect on the number of shares of Class A common stock that
stockholders of Xoom.com will receive.

    PRIVACY CONCERNS, GOVERNMENT REGULATION AND LEGAL UNCERTAINTIES COULD HAVE
     AN ADVERSE EFFECT ON NBCI'S BUSINESS AND RESULTS OF OPERATIONS

    Laws and regulations that apply directly to communications or commerce over
the Internet are becoming more prevalent. The most recent session of the United
States Congress resulted in Internet laws regarding privacy and the protection
of children, copyrights, taxation and the transmission of sexually explicit
material. The European Union recently enacted its own privacy regulations and
other countries may do so in the future. In addition, new laws may be adopted in
the United States and in other countries covering issues such as music
licensing, broadcast licensing fees and the characteristics

                                       32
<PAGE>
and quality of Internet services. Laws regulating the Internet, however, remain
largely unsettled, even in areas where there has been some legislative action.
It may take years to determine whether and how existing laws that govern
intellectual property, privacy, libel and taxation apply to the Internet. The
development of laws governing these areas, or the application to the Internet of
existing laws not designed for the Internet, may decrease the growth in the use
of the Internet. In addition, the growth and development of the e-commerce
market may prompt calls for more stringent consumer protection laws, both in the
United States and abroad, that may impose additional burdens on companies
conducting business online. The adoption or modification of laws or regulations
relating to the Internet could adversely affect NBCi's business.

    The Federal Communications Commission is currently reviewing its regulatory
positions on data transmissions over telecommunications networks and could seek
to impose some form of telecommunications carrier regulation on
telecommunications functions of information services. State public utility
commissions generally have declined to regulate information services, although
the public service commissions of some states continue to review potential
regulation of such services. Future regulation or regulatory changes could have
an adverse effect on NBCi's business and results of operations.

    NBCI'S INABILITY TO PROTECT ITS INTELLECTUAL PROPERTY RIGHTS COULD HAVE A
     MATERIAL ADVERSE EFFECT ON ITS BUSINESS AND FINANCIAL CONDITION

    NBCi views its technology as proprietary and will seek to protect it under
existing United States and international laws relating to protection of
intellectual property. NBCi will also develop internal procedures to control
access to and dissemination of NBCi's proprietary information. Despite NBCi's
precautions, third parties may succeed in misappropriating NBCi's intellectual
property or independently developing similar intellectual property. Protecting
NBCi's intellectual property against infringement could result in substantial
legal and other costs and could divert NBCi's limited management resources and
attention. This could adversely impact NBCi's business and the results of its
operations.

    Some of the technology to be incorporated into NBCi's Web sites is based on
technology licensed from third parties. As NBCi continues to introduce new
services, it may need to license additional technology. If NBCi is unable to
license needed technology in a timely manner and on commercially reasonable
terms, NBCi could experience delays and reductions in the quality of its
services, all of which could adversely affect its business and results of
operations. NBCi's reputation and the value of its proprietary information could
also be adversely affected by actions of third parties to whom NBCi licenses its
proprietary information and intellectual property. If someone asserts a claim
relating to proprietary technology or information against NBCi, NBCi may seek
licenses to such intellectual property. NBCi cannot assure you, however, that it
will be able to obtain licenses on commercially reasonable terms, if at all. The
failure to obtain any necessary licenses or other rights could have a material
adverse effect on NBCi's business and results of operations.

    Each of the NBCi businesses has been subject to claims that they have
allegedly infringed the proprietary rights of third parties, and NBCi cannot
assure you that third parties will not assert claims against NBCi or the NBCi
businesses in the future. These claims, whether or not meritorious, sometimes
result in litigation and could become a drain on NBCi's management and financial
resources. If successful, claims of this nature could subject NBCi to liability
for money damages as well as injunctive relief restricting NBCi's use of
intellectual property important to its operations, and could ultimately cause
NBCi to lose rights to some of its intellectual property. Any of these events
could have a material adverse effect on NBCi's business and results of
operations.

                                       33
<PAGE>
    NBCI COULD BE SUBJECT TO LIABILITY FOR ONLINE CONTENT THAT MAY NOT BE
     COVERED BY NBCI'S INSURANCE

    The nature and breadth of information to be disseminated on NBCi's Web sites
and through the sites of its members could expose it to liability in various
areas, including claims relating to:

    - product information and reviews NBCi will offer;

    - the content and publication of various materials based on defamation,
      libel, negligence, personal injury and other legal theories;

    - copyright or trademark infringement and wrongful action due to the actions
      of third parties;

    - use of third party content made available through NBCi's Web site or
      through content and material posted by members on their home pages or in
      chat rooms and bulletin boards; and

    - damages arising from the use or misuse of the free e-mail services NBCi
      will offer.

    Claims of these kinds against NBCi could result in NBCi incurring
substantial costs and could also be a drain on its financial and other
resources. If the number or severity of claims of this nature were significant,
NBCi would need to implement measures to reduce its exposure and potential
liability. In addition to being a drain on NBCi's resources, this could also
require taking measures that could make its services less attractive to its
members and visitors. This in turn could reduce traffic on NBCi's Web sites,
negatively impact its member and user base, and reduce NBCi's revenue from
e-commerce and advertising. NBCi's general liability insurance may be
insufficient to cover expenses and losses arising in connection with any claims
against NBCi. To the extent NBCi's insurance coverage does not cover liability
or expenses NBCi incurs, NBCi's business and results of operations would be
adversely affected.

    E-COMMERCE ACTIVITIES MAY EXPOSE NBCI TO UNCERTAIN LEGAL RISKS AND POTENTIAL
     LIABILITIES

    As part of its business, NBCi will enter into agreements with sponsors,
content providers, service providers and merchants under which it is entitled to
receive a share of revenue from the purchase of goods and services by users of
NBCi's Web sites. In addition, NBCi will provide hosting and other services to
online merchants. These types of arrangements may expose NBCi to additional
legal risks and uncertainties, including potential liabilities relating to the
products and services offered by such third parties.

    Although NBCi will maintain liability insurance, insurance may not cover
these claims or may not be adequate. Even to the extent these types of claims do
not result in material liability, investigating and defending claims is
expensive and, if the number or severity of claims defended were significant,
this could have a material adverse effect on NBCi's business and operations.

    NBCI COULD FACE LIABILITY FROM LEGAL PROCEEDINGS OF XOOM.COM AND SNAP THAT
     COULD ADVERSELY AFFECT NBCI'S BUSINESS AND RESULTS OF OPERATIONS


    Because SNAP and Xoom.com will become wholly owned subsidiaries of NBCi,
claims made against SNAP and Xoom.com will impact the financial condition and
results of operations of NBCi. SNAP is currently litigating one matter, which is
described on page 184. Xoom.com is also litigating three matters which are
described on page 147. An unfavorable outcome in any of this litigation could
adversely affect the business and results of operations of NBCi and the market
price of NBCi's common stock.


    IF FUTURE ACQUISITIONS ARE NOT SUCCESSFUL, OR IF NBCI IS NOT ABLE TO
     STRUCTURE FUTURE ACQUISITIONS IN A FINANCIALLY EFFICIENT MANNER, THERE
     COULD BE AN ADVERSE EFFECT ON NBCI'S BUSINESS AND RESULTS OF OPERATIONS

    Acquiring complementary businesses, products and technologies is an integral
part of NBCi's business strategy. This acquisition strategy will subject NBCi to
integration risks similar to those it faces in integrating the NBCi businesses.
In addition, the success of the acquisitions will be dependent upon the ability
of NBCi's management to maximize NBCi's financial and strategic position when

                                       34
<PAGE>
incorporating the technology or businesses. Any of these risks could prevent
NBCi from realizing significant benefits from NBCi's acquisitions.

    NBCi will face increased competition with other entities for desirable
acquisition targets. Like several of its competitors and other Internet
companies, NBCi expects to issue common stock in future acquisitions. If the
market price of NBCi's common stock suffers declines which are disproportionate
relative to its competitors or fails to keep pace with any increases in the
price of the stock of its competitors, NBCi may not be able to compete with
other entities for desirable acquisition candidates. NBCi's inability to acquire
complementary businesses, products and technologies may have a material adverse
effect on NBCi's business and results of operations.

    In addition, issuing common stock in acquisitions will dilute existing
stockholders interests in NBCi, while the use of cash will deplete cash
reserves. NBCi anticipates that it will be unable to account for its
acquisitions under the "pooling of interests" method of accounting in the future
and, therefore, expects to incur significant, one-time write-offs and
amortization charges. These write-offs and charges would decrease NBCi's future
earnings or increase its future losses. Due to all of the foregoing, NBCi's
inability to structure acquisitions in a financially efficient manner may have a
material adverse effect on NBCi's business and results of operations.

    IF NBCI'S CAPITAL IS INSUFFICIENT TO PROMOTE ITS BUSINESS, AND IF NBCI
     CANNOT OBTAIN NEEDED FINANCING, IT WILL BE UNABLE TO PROMOTE NBCI'S BRAND
     NAMES, EXPLOIT ACQUISITION OPPORTUNITIES AND OTHERWISE MAINTAIN ITS
     POSITION RELATIVE TO ITS COMPETITORS

    Upon consummation of the transactions, NBCi will have sufficient capital
resources to support its operations at least for the next 12 months.
Nevertheless, NBCi anticipates that it will need to raise funds to maintain and
develop NBCi's position in the marketplace. It may be difficult or impossible
for NBCi to obtain financing on favorable terms, if at all. Neither GE nor its
affiliates, including NBC, has made any commitment to provide financing to NBCi.
NBCi cannot assure you that there will be a market for NBCi's securities at any
time when NBCi may seek to raise needed funds by equity financing. Raising funds
by issuing equity securities or convertible debt securities will dilute the
percentage ownership of NBCi's stockholders, subject to NBC's exercise of its
preemptive rights, and there can be no assurance that an offering of securities
would be completed successfully. Also, new securities NBCi may issue could have
rights senior to the rights of NBCi's common stock. If NBCi cannot obtain needed
financing, it could jeopardize NBCi's ability to complete the integration of the
Xoom.com, SNAP and the NBC contributed Internet businesses and otherwise meet
its business plan and NBCi will likely be unable to promote its brand names,
exploit acquisition opportunities and otherwise maintain NBCi's position
relative to that of its competitors, which would have a material adverse effect
on NBCi's business and results of operations.

    IF IMPORTANT STRATEGIC RELATIONSHIPS ARE DISCONTINUED FOR ANY REASON, THERE
     WOULD BE A MATERIAL ADVERSE EFFECT ON NBCI'S BUSINESS AND FINANCIAL
     CONDITION

    Although strategic relationships are a key factor in NBCi's overall business
strategy, its strategic partners may not view their relationships with NBCi as
significant to their own business. There is a risk that parties with whom NBCi
will have strategic alliance agreements may not perform their obligations as
agreed. NBCi expects that its arrangements with strategic partners generally
will not establish minimum performance requirements but instead rely on the
voluntary efforts of NBCi's partners. In addition, NBCi expects that most of its
agreements with strategic partners will be terminable by either party with
little notice. If important strategic relationships are discontinued for any
reason, NBCi's business and results of operations may be adversely affected.

                                       35
<PAGE>
    THE YEAR 2000 PROBLEM COULD CAUSE NBCI'S SOFTWARE PRODUCTS AND THOSE OF ITS
     SUPPLIERS TO MALFUNCTION, WHICH COULD PREVENT OR LIMIT ACCESS TO NBCI'S
     ONLINE PROPERTIES AND COULD BE COSTLY TO REMEDY

    Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. As a result, software that
records only the last two digits of the calendar year may not be able to
distinguish whether "00" means 1900 or 2000. This may result in software
failures or the creation of erroneous results.

    Each of the NBCi businesses has made inquiries of vendors of systems it
believes to be critical to its business regarding Year 2000 readiness. Although
the NBCi businesses have received various assurances, they have not received
affirmative documentation of Year 2000 compliance from any of these vendors and
operational tests have not been performed on the systems. NBCi generally will
not have contractual rights with third party providers should their equipment or
software fail due to Year 2000 issues. If this third party equipment or software
does not operate properly with regard to Year 2000, NBCi may incur unexpected
expenses to remedy any problems. These expenses could potentially include
purchasing replacement hardware and software. The NBCi businesses have not
determined the state of compliance of some of their third-party suppliers of
services such as warehousing and fulfillment services, phone companies, long
distance carriers, financial institutions and electric companies, the failure of
any one of which could severely disrupt NBCi's ability to carry on its business.

    NBCi anticipates that its review of Year 2000 issues and any remediation
efforts will continue throughout the remainder of calendar 1999. The costs
incurred to date by the NBCi businesses to remediate Year 2000 issues have not
been material. If any Year 2000 issues are uncovered with respect to these
systems or its other internal systems, NBCi believes that it will be able to
resolve these problems without material difficulty, as replacement systems are
available on commercially reasonable terms. NBCi presently estimates that the
total remaining cost of addressing Year 2000 issues will not exceed $500,000.
NBCi derived these estimates using a number of assumptions, including the
assumption that the NBCi businesses have already identified their most
significant Year 2000 issues. However, these assumptions may not be accurate,
and actual results could differ materially from those anticipated. In view of
the Year 2000 review to date made by the NBCi businesses, the recent development
of their products and services, the recent installation of the networking
equipment and servers that NBCi will use in operating the NBCi business, and the
limited activities that remain to be completed, NBCi does not consider
contingency planning to be necessary at this time.

    NBCi's applications will operate in complex network environments and
directly and indirectly interact with a number of other hardware and software
systems. NBCi is unable to predict to what extent its business may be affected
if its systems or the systems that operate in conjunction with its systems
experience a material Year 2000 failure. Known or unknown errors or defects that
affect the operation of software and systems that NBCi will use in operating the
NBCi businesses could result in delay or loss of revenue, interruption of
services, cancellation of contracts and memberships, diversion of development
resources, damage to NBCi's reputation, increased service and warranty costs,
and litigation costs, any of which could adversely affect NBCi's business,
financial condition and results of operations. The worst case scenario is that
the Internet fails and NBCi is unable to offer any services on its Web sites or
make any of its direct e-commerce offerings.

INVESTMENT RISKS

    NBCI'S CLASS A COMMON STOCK HAS NOT BEEN PUBLICLY TRADED AND THE MARKET
     PRICE OF NBCI COMMON STOCK MAY DECLINE AFTER THE TRANSACTIONS

    Prior to the closing of the transactions, no public market existed for
NBCi's Class A common stock. The market price of NBCi's Class A common stock may
bear no relation to the market price of the Xoom.com common stock prior to the
closing of the transactions. In addition, financial analysts may not accept or
understand NBCi's business model which may cause the market price of the NBCi
Class A common stock to decline or trade at a depressed price.

    NBCI'S STOCK PRICE MAY BE VOLATILE BASED ON A NUMBER OF FACTORS, SOME OF
     WHICH ARE NOT IN NBCI'S CONTROL

    The trading price of NBCi's Class A common stock is likely to be highly
volatile. NBCi's stock price could be subject to wide fluctuations in response
to a variety of factors, including:

    - actual or anticipated variations in quarterly operating results;

    - announcements of technological innovations;

    - new products or services offered by NBCi or its competitors;

    - changes in financial estimates by securities analysts;

    - conditions or trends in the Internet industry and the portal and community
      services segment in particular;

    - NBCi's announcement of significant acquisitions, strategic partnerships,
      joint ventures or capital commitments;

    - additions or departures of key personnel;


    - sales of common stock by NBCi or its stockholders, which could occur at
      any time after the closing of the transactions; and


    - other events or factors that may be beyond NBCi's control.

    In addition, The Nasdaq National Market, where most publicly held Internet
companies are traded, has recently experienced extreme price and volume
fluctuations. These fluctuations often have been unrelated or disproportionate
to the operating performance of these companies. While the trading prices of
many Internet companies' stocks have recently declined from their 52-week highs,
these stocks continue to trade at multiples of earnings or revenues which are
substantially above historic levels. These trading prices and multiples may not
be sustainable. These broad market and industry factors may materially adversely
affect the market price of NBCi's common stock, regardless of its actual
operating performance. In the past, following periods of volatility in the
market price of an individual company's securities, securities class action
litigation often has been instituted against that company. This type of
litigation, if instituted, could result in substantial costs and a diversion of
management's attention and resources.

    THE SIGNIFICANT INFLUENCE OF NBC AND ANTI-TAKEOVER PROVISIONS IN THE
     TRANSACTION DOCUMENTS INCLUDING NBCI'S CHARTER DOCUMENTS COULD NEGATIVELY
     IMPACT NBCI'S STOCKHOLDERS

    NBC will have significant influence with respect to the management and
strategy of NBCi. As a result of NBC's influence, NBC may be able to exercise
effective control over significant corporate transactions which may delay or
prevent a change in control of NBCi resulting in a lower stock price. NBC and
its affiliates have enhanced voting rights with respect to the approval of
significant corporate acquisition transactions. In the event that a third party
initiates a tender offer for NBCi common stock or NBCi agrees to enter into any
transaction which would result in a change of control of NBCi, the limitations
on NBC's ability to acquire additional shares of NBCi, to solicit proxies in
connection with an amendment to NBCi's restated certificate of incorporation or
for the election of Class A Directors, or to propose to the holders of the Class
A common stock a merger, business combination or similar transaction will
terminate. Moreover, NBC has the right to terminate NBCi's use of the NBC
trademarks and logos in the event of a change of control of NBCi. Other
provisions of NBCi's charter documents and in the transaction documents could
make it more difficult for a third party to acquire NBCi, even if doing so would
be beneficial to NBCi's stockholders. Any of these factors could impede or
prevent transactions that would cause a change in control of NBCi's company.
This might discourage bids for NBCi's common stock at a premium over the market
price of NBCi's common stock and adversely affect the trading price of its
common stock.

    SALES OF SUBSTANTIAL AMOUNTS OF NBCI'S COMMON STOCK IN THE OPEN MARKET COULD
     DEPRESS NBCI'S STOCK PRICE

    If NBCi's stockholders sell substantial amounts of NBCi's common stock in
the public market following the closing of the transactions, including shares
issued upon the exercise of outstanding options and warrants, the market price
of NBCi's common stock could fall. Such sales might also make it more difficult
for NBCi to sell equity or equity related securities in the future at a time and
price that NBCi deems appropriate.

    Sales of a large number of shares of common stock in the public market
following the closing of the transactions, or the belief that such sales could
occur, could cause a drop in the market price of NBCi's common stock and could
impair NBCi's ability to raise capital through offerings of NBCi's equity
securities. Following the closing of the transactions, there are expected to be
approximately 27,365,472 shares of NBCi Class A common stock outstanding. All of
the shares issued to the Xoom.com stockholders will be freely tradable without
restrictions or further registration under the Securities Act, unless such
shares are held by any NBCi "affiliate," as that term is defined under the
Securities Act.

    The 7,147,584 shares of Class A common stock held by CNET and the 24,550,708
shares of Class B common stock held by NBC and its affiliates will not be
available for sale in the public market without registration or an available
exemption from the Securities Act. NBC, CNET and Chris Kitze, among others, will
enter into a registration rights agreement with NBCi under which they will be
able to register their shares. Upon the sale of Class B common stock by NBC or
its affiliates, such shares will be converted into Class A common stock. The
exercise by NBC, CNET or Chris Kitze of these registration rights with respect
to a significant portion of the shares of common stock to be issued in the
transactions could substantially increase the number of shares of Class A common
stock available for sale in the public market. In particular, CNET will be
entitled to exercise its initial demand right before the other parties to the
registration rights agreement for a period of 60 days following consummation of
the transactions. As a result, any such exercise by NBC, CNET or Chris Kitze or
the perception that such exercise could occur, could materially adversely affect
prevailing market prices for NBCi common stock and the ablitity of NBCi to raise
equity capital in the future.

                       SELECTED HISTORICAL FINANCIAL DATA

    The following selected combined financial data should be read in conjunction
with the combined Financial Statements and Notes thereto of the NBC Multimedia
Division, which consists of NBC.com, NBC-IN.com and VideoSeeker, beginning on
page F-51 of this proxy statement/prospectus and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" beginning on page 208
of this proxy statement/prospectus. The combined statement of operations data
for each of the years in the two-year period ended December 31, 1998 and the
combined balance sheet data at December 31, 1997 and 1998 are derived from the
combined financial statements of the NBC Multimedia Division which have been
audited by KPMG LLP, independent accountants, beginning on page F-51 of this
proxy statement/prospectus. The statement of operations data for each of the six
months ended June 30, 1998 and 1999, and the balance sheet data as of June 30,
1999, are derived from the unaudited interim combined financial statements of
the NBC Multimedia Division beginning on page F-51 of this proxy
statement/prospectus. The unaudited financial statements have been prepared on
substantially the same basis as the audited financial statements and, in the
opinion of management, include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the results of
operations for such periods. Historical results are not necessarily indicative
of the results to be expected in the future, and results of interim periods are
not necessarily indicative of results for the entire year.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

    At the special meeting, stockholders of Xoom.com will be asked to vote

    - the adoption of the merger agreement;

    - Xoom.com's adoption, as the sole stockholder of NBCi, of the contribution

    Only stockholders of record of Xoom.com common stock at the close of

stock held as of the record date.

VOTING AND REVOCATION OF PROXIES

    The Xoom.com proxy accompanying this document is solicited on behalf of
Xoom.com's board of directors. The required quorum for the transaction of
business at the special meeting is a majority of the votes eligible to be cast
by holders of shares of common stock issued and outstanding on the record date.
For purposes of determining the presence of a quorum, abstentions and broker
non-votes will be counted by Xoom.com as present at the meeting.

    Stockholders are requested to complete, date and sign the accompanying proxy
and promptly return it in the accompanying envelope or otherwise mail it to
Xoom.com. All properly executed proxies received by Xoom.com prior to the

voting such proxies.

STOCKHOLDER VOTE

    Adoption of the merger agreement by Xoom.com's stockholders is required by
the General Corporation Law of the State of Delaware. By approving the adoption
of the merger agreement you will approve the merger of Xenon 3 with and into
Xoom.com. The adoption of the merger agreement requires the affirmative vote of
the holders of a majority of the shares of Xoom.com common stock outstanding and
entitled to vote at the special meeting. Abstentions and broker non-votes are
not affirmative votes and, therefore, will have the same effect as votes against
the adoption of the merger agreement.

    WITH RESPECT TO THE VOTE TO ADOPT THE MERGER AGREEMENT, THE REQUIRED VOTE OF
THE STOCKHOLDERS OF XOOM.COM IS BASED UPON THE NUMBER OF OUTSTANDING SHARES OF
XOOM.COM COMMON STOCK RATHER THAN UPON THE SHARES ACTUALLY VOTED IN PERSON OR BY
PROXY AT THE SPECIAL MEETING. THEREFORE, IF THE HOLDERS OF ANY SUCH SHARES FAIL
TO EITHER SUBMIT A PROXY OR VOTE IN PERSON AT THE SPECIAL MEETING, SUCH FAILURE
WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE ADOPTION OF THE MERGER
AGREEMENT.

    Although not required by the General Corporation Law of the State of
Delaware, the Xoom.com board of directors is seeking your approval of Xoom.com's
adoption of the contribution agreement. Under the contribution agreement, the
board of directors of Xoom.com has agreed to cause Xoom.com to vote for or
against the adoption of the contribution agreement in accordance with the vote
of the stockholders of Xoom.com. The approval of Xoom.com's adoption of the
contribution agreement requires the affirmative vote of the holders of a
majority of the shares of Xoom.com present in person or by proxy at the special
meeting and entitled to vote. Broker non-votes are not entitled to vote on the
approval of Xoom.com's adoption of the contribution agreement and therefore will
not affect the outcome of the vote. Abstentions will have the effect of a vote
against Xoom.com's adoption of the contribution agreement.

    The Xoom.com board of directors is also seeking your approval of the stock
incentive plan. The approval of the stock incentive plan requires the
affirmative vote of the holders of a majority of the shares of Xoom.com present
in person or by proxy at the special meeting and entitled to vote. Broker
non-votes are not entitled to vote on the approval of the stock incentive plan
and therefore will not affect the outcome of the vote. Abstentions will have the
effect of a vote against the stock incentive plan.

    On the date the merger agreement and contribution agreement were signed,
Chris Kitze, the chairman of Xoom.com entered into an agreement with NBC which
obligates him to vote all of his shares in favor of the adoption of the merger
agreement and in favor of Xoom.com's adoption of the contribution agreement. As
of the record date, Mr. Kitze was deemed to beneficially own in the aggregate
approximately 16.4% of the outstanding shares of Xoom.com common stock. As of
the record date, NBC owned 960,028 shares of Xoom.com common stock, which
represents approximately 4.7% of the outstanding shares of Xoom.com common
stock. NBC has agreed to vote all of such shares for the adoption of the merger
agreement and for Xoom.com's adoption of the contribution agreement.

RECOMMENDATION OF XOOM.COM BOARD OF DIRECTORS

    After careful consideration, the board of directors of Xoom.com has declared
the advisability of and approved the merger agreement, the contribution
agreement and the transactions contemplated thereby and has determined that the
merger agreement and the contribution agreement are fair to, and in the best
interests of, Xoom.com and its stockholders. Robert C. Harris, Jr., a director
of Xoom.com, is also the senior managing director of Bear Stearns, which was
engaged to render a fairness opinion on the transactions. Mr. Harris abstained
from voting on the merger agreement, the contribution agreement and the
transactions contemplated thereby due to the potential conflict of interest
arising from his position with Bear Stearns. All other directors of Xoom.com
voted in favor of the transactions. THE BOARD OF DIRECTORS OF XOOM.COM
RECOMMENDS A VOTE IN FAVOR OF THE ADOPTION OF THE

                                       45

BACKGROUND

    In August of 1998, Mr. Chris Kitze, chairman of the board of directors of
Xoom.com, requested Bear Stearns to explore strategic alternatives for Xoom.com.
As a result of the efforts of Bear Stearns from August 1998 through March 1999,
Mr. Kitze, Mr. Marc Sznajderman, vice president, corporate development of
Xoom.com, and Mr. Russell S. Hyzen, vice president, business development of
Xoom.com, discussed potential strategic relationships, including the sale of
Xoom.com with a number of companies in the multimedia industry.

    At board of directors meetings held on September 16, 1998 and October 7,
1998, the board of directors of Xoom.com discussed Xoom.com's strategic
alternatives including possible businesses which Xoom.com could merge with or be
acquired by.

    In addition to the efforts of Bear Stearns, Xoom.com's management publicized
its willingness to consider transactions with a strategic partner through
statements at analyst meetings, financial conferences and on the road shows for
its initial public offering and follow-on offering.

    On February 16, 1999, SNAP's senior management met to review alternatives
preferred for becoming a public company. The alternatives reviewed included an
initial public offering, the acquisition of a private company and the
acquisition of a public company. After concluding that SNAP's operating history
was too limited for an initial public offering, and considering the need for
SNAP to expand, particularly in the areas of community and chat, the management
team concluded that a strategic transaction with Xoom.com would be the best
choice. On February 24, 1999, this proposal was presented to SNAP's board of
directors and Mr. Halsey Minor, chief executive officer of SNAP and CNET, and
Mr. Martin Yudkovitz of NBC, a member of SNAP's board, were authorized to
initiate discussions for this purpose. Subsequently, Mr. Minor and Mr. Yudkovitz
contacted Mr. Kitze.

    During March 1999, Xoom.com and NBC entered into preliminary discussions
regarding a possible business combination or investment that would have resulted
in a change in control of Xoom.com. On April 8, 1999, those discussions ended as
Xoom.com and NBC could not reach agreement on the transaction terms.

    On April 12, 1999, NBC contacted Mr. Kitze to reopen discussions on a
possible strategic alliance of NBC and Xoom.com.

    On April 14, 1999, Mr. Kitze met with Mr. Thomas Rogers of NBC and Mr.
Yudkovitz to discuss a comprehensive strategic alliance with NBC. NBC
conditioned its offer on Xoom.com and some of its stockholders entering into an
exclusive negotiation agreement with NBC.

    On April 15, 1999, with only NBC having expressed a strong interest in
pursuing a strategic relationship with Xoom.com, Xoom.com and NBC entered into a
non-solicitation and confidentiality agreement. Under this letter agreement,
Xoom.com and NBC agreed to negotiate exclusively with each other for a period of
thirty days concerning a potential strategic relationship. After Xoom.com and
NBC entered into this letter agreement, Bear Stearns was requested to prepare
its opinion in connection with the proposed transactions involving NBC. At this
time, Bear Stearns was directed not to and did not seek or pursue alternative
transactions to the proposed transactions involving NBC, including the possible
sale of Xoom.com as an entirety.

                                       47

    On April 20, 1999, representatives of Xoom.com, NBC and SNAP met in San
Francisco to conduct business and legal due diligence. During this time, the
companies exchanged financial information and discussed their respective
business models and financial projections. The companies agreed to exchange
additional information and continue the preliminary due diligence process in
future meetings.

    From April 20, 1999 through April 25, 1999 the management of Xoom.com and
NBC, together with their respective legal and financial advisors negotiated the
principal terms of the agreements providing for the formation of NBCi.

    On April 26, 1999, a special meeting of Xoom.com's board of directors was
held. At the meeting, Mr. Kitze described the proposal from NBC to combine
selected Internet-related businesses of CNET and NBC with the existing business
of Xoom.com and issue equity interests in the new entity. Bear Stearns informed
the board of directors of comparable transactions that have been entered into
involving media-related owned businesses and Internet-related businesses or
involving the multimedia industry generally. The business rationale for the
transactions was also discussed. At this meeting, the directors raised the
advisability of engaging Hambrecht & Quist to provide the board of directors
with an additional fairness opinion. At the conclusion of this meeting, the
board of directors authorized Xoom.com's management to proceed with the
transaction and authorized the engagement of Hambrecht & Quist to render a
fairness opinion.

    On April 28 and 29, 1999, Mr. Kitze, Mr. Sznajderman and Mr. Harris, as a
representative of Bear Stearns, met with members of NBC to continue to discuss
additional terms of the proposed transactions. From April 30, 1999 through May
9, 1999, Xoom.com, NBC, SNAP and CNET, together with their respective legal and
financial advisors, conducted due diligence reviews and negotiated the final
terms of the definitive agreements.

    On May 9, 1999, Xoom.com's board of directors met with senior management and
Xoom.com's financial advisors and legal counsel at a special meeting of the
board of directors to review the status of the negotiations with NBC and CNET,
and the terms of the draft agreements, including the stock option agreement. At
this meeting, representatives of Bear Stearns and Hambrecht & Quist reviewed the
financial terms of the transactions and rendered their oral opinions that, after
issuance of NBCi shares to Xoom.com stockholders in the merger of Xenon 3 with
Xoom.com, the aggregate issuance of NBCi shares to NBC and CNET in the
transactions contemplated by the merger agreement and the contribution
agreement, taken together, both before and after conversion of the NBCi
convertible notes, in exchange for the aggregate contribution of SNAP and the
NBC contributed Internet businesses, was fair, from a financial point of view,
to Xoom.com and its stockholders. Bear Stearns also opined at the meeting that
the issuance of NBCi shares to CNET in the transactions contemplated by the
merger agreement, if the transactions contemplated by the contribution agreement
are not consummated, was fair, from a financial point of view, to Xoom.com and
its stockholders. Following these presentations, Xoom.com's board of directors
engaged in a full discussion of the terms of the proposed transactions and their
advisability. At the conclusion of this meeting, Xoom.com's board of directors
approved the terms of the transaction documents and authorized management to
proceed with the execution of the transaction documents.

    During the night of May 9, 1999, the parties executed the merger agreement,
the agreement and plan of contribution, investment and merger, prior to its
amendment, and the related agreements discussed beginning on page 90.

    The transactions were jointly announced by NBC, CNET and Xoom.com on the
morning of May 10, 1999.

    On June 9, 1999, a special meeting of Xoom.com's board of directors was
held. At the meeting the board of directors discussed preliminarily the proposed
terms of an equity investment by NBC or its affiliates in Xoom.com with a
related restructuring of the transactions with NBC and its affiliates
contemplated by the agreement executed on May 9, 1999. Subsequently, on June 11,
1999, Xoom.com's board of directors met with senior management and Xoom.com's
financial advisors and legal counsel to

                                       48
<PAGE>
review the terms and the advisability of the equity investment and restructuring
proposal. At the meeting, Mr. Harris described the equity investment and
restructuring proposal. Representatives of Bear Stearns and Hambrecht & Quist
confirmed that their respective opinions rendered on May 9, 1999 remained in
full force and effect and were unaffected by the equity investment and
restructuring proposal. Following these presentations, Xoom.com's board of
directors engaged in a full discussion of the terms of the proposed equity
investment and restructuring and its advisability. At the conclusion of this
meeting, Xoom.com's board of directors approved the terms of the stock purchase
agreement, registration rights agreement and the amended and restated agreement
and plan of contribution, investment and merger described below and authorized
management to proceed with the execution of such documents.

    On June 11, 1999, Xoom.com and some of its subsidiaries and NBC and some of
its affiliates entered into:

    - a stock purchase agreement,

    - the amended and restated agreement and plan of contribution, investment
      and merger, and

    - a registration rights agreement with respect to the common stock purchased
      pursuant to the stock purchase agreement.

The restructuring was jointly announced by NBC and Xoom.com on the evening of
June 14, 1999.

    On July 7, 1999, Xoom.com's board of directors met with senior management
and Xoom.com's financial advisors and legal counsel at a special meeting to
discuss the terms and advisability of a second restructuring proposal. At the
meeting, Mr. Harbottle, vice president, finance and chief financial officer of
Xoom.com, described the proposal. A representative of Hambrecht & Quist
confirmed that its opinion rendered on May 9, 1999 remained in full force and
effect and was unaffected by the second restructuring proposal. Following these
presentations, Xoom.com's board of directors engaged in a full discussion of the
terms of the proposal and its advisability. At the conclusion of this meeting,
Xoom.com's board approved the terms of the contribution agreement and authorized
management to proceed with the execution of the contribution agreement. The
board of directors' approval was subject to confirmation from Bear Stearns that
its opinion rendered on May 9, 1999 remained in full force and effect and was
unaffected by the second restructuring proposal.

    On July 8, 1999, Bear Stearns confirmed that its opinion rendered on May 9,
1999 remained in full force and effect and was unaffected by the second
restructuring proposal. Subsequently, on July 8, 1999, Xoom.com and some of its
subsidiaries and NBC and some of its affiliates entered into the contribution
agreement, which amended and restated the amended and restated agreement and
plan of contribution, investment and merger, dated as of June 11, 1999.

    On July 8, 1999, the name of NBCi was changed from Xenon 2, Inc. to NBC
Internet, Inc. following the execution by NBC, Xoom.com and SNAP of a license
agreement and the execution by NBC and NBCi of a trademark agreement relating to
NBCi's name and the use of the NBC mark in connection with this proxy
statement/prospectus.

    On October 18, 1999, Xoom.com's board of directors met with senior
management and Xoom.com's legal counsel at a special meeting to discuss the
terms and advisability of amending the merger agreement and the contribution
agreement. At the meeting, Mr. Harbottle, vice president, finance and chief
financial officer of Xoom.com, described the proposed amendments.
Representatives of Bear Stearns and Hambrecht & Quist had previously confirmed
to Xoom.com's senior management that their opinions rendered on May 9, 1999
remained in full force and effect and were unaffected by the proposed
amendments. Following these presentations, Xoom.com's board of directors engaged
in a full discussion of the terms of the proposed amendments and their
advisability. At the conclusion of this meeting, Xoom.com's board approved the
terms of the proposed amendments and authorized management to proceed with their
execution.

                                       49

    The amendments included clarification of the manner in which the options to
purchase units of SNAP would be converted into options to purchase shares of
Class A common stock as described on page 79 and an increase in the total number
of options SNAP could issue prior to the closing to 17% of the units of SNAP.
The amendments also increased the total amount of advertising spots agreed to be
purchased by NBCi over a four-year period under the advertising agreement from
$380 million to $405 million.


    On October 20, 1999, the parties to the merger agreement and the
contribution agreement entered into the amendments.

RECOMMENDATION OF XOOM.COM'S BOARD OF DIRECTORS AND REASONS FOR THE TRANSACTIONS

    At its meeting on May 9, 1999, the board of directors of Xoom.com:

    - determined that the terms of the merger agreement and contribution
      agreement, as then in effect, and the transactions contemplated thereby
      are advisable and fair to and in the best interests of Xoom.com and its
      stockholders,

    - approved the merger agreement and the contribution agreement,

    - directed that the merger agreement and the contribution agreement be
      submitted for consideration by the Xoom.com stockholders and

    - recommended that the Xoom.com stockholders vote for the adoption of the
      merger agreement and for Xoom.com's adoption of the contribution
      agreement.

    In reaching this conclusion, the board of directors of Xoom.com, with the
assistance of its financial and legal advisors, considered and analyzed a number
of factors, including, without limitation, the following:

    - the oral presentation of Bear Stearns and its oral opinion, later
      confirmed in writing, that, after issuance of NBCi shares to Xoom.com
      stockholders in the merger of Xenon 3 with Xoom.com, (a) the aggregate
      issuance of NBCi shares to NBC and CNET in the transactions contemplated
      by the merger agreement and the contribution agreement, taken together
      (both before and after conversion of the NBCi convertible notes), in
      exchange for the aggregate contribution of SNAP and the NBC contributed
      Internet businesses, and (b) the issuance of NBCi shares to CNET in the
      transactions contemplated by the merger agreement, if the transactions
      contemplated by the contribution agreement are not consummated, in
      exchange for CNET's contribution of its equity interests in SNAP, were
      fair from a financial point of view, to Xoom.com and its stockholders. On
      June 11, 1999, Bear Stearns confirmed that its opinion remained in full
      force and effect and was unaffected by the equity investment and
      restructuring entered into as of June 11, 1999. On July 8, 1999 Bear
      Stearns confirmed that its opinion remained in full force and effect and
      was unaffected by the second restructuring entered into as of July 8,
      1999. Prior to the meeting of the board of directors of Xoom.com on
      October 18, 1999, Bear Stearns confirmed that its opinion remained in full
      force and effect and was unaffected by the amendments to the merger
      agreement and contribution agreement entered into as of October 20, 1999.

    - the oral presentation of Hambrecht & Quist and its oral opinion, later
      confirmed in writing, that, after issuance of NBCi shares to Xoom.com
      stockholders in the merger of Xenon 3 with Xoom.com, the aggregate
      issuance of NBCi shares to NBC and CNET in the transactions contemplated
      by the merger agreement and the contribution agreement, taken together,
      both before and after conversion of the NBCi convertible notes, in
      exchange for the aggregate contribution of SNAP and the NBC contributed
      Internet businesses, was fair from a financial point of view, to Xoom.com
      and its stockholders. On June 11, 1999, Hambrecht & Quist confirmed that
      its opinion remained in full force and effect and was unaffected by the
      equity investment and restructuring entered into as of June 11, 1999. On
      July 7, 1999, Hambrecht & Quist confirmed that its opinion remained in
      full force and effect and was unaffected by the

                                       50
<PAGE>
      second restructuring entered into as of July 8, 1999. Prior to the meeting
      of the board of directors of Xoom.com on October 18, 1999, Hambrecht &
      Quist confirmed that its opinion remained in full force and effect and was
      unaffected by the amendments to the merger agreement and contribution
      agreement entered into as of October 20, 1999.


    - reports from Xoom.com's management and legal and financial advisors on
      specific terms of the merger agreement, contribution agreement and the
      other related agreements described below on page 90;


    - the legal and business due diligence examination of SNAP and the NBC
      contributed Internet businesses conducted by Xoom.com management, and its
      legal and financial advisors;

    - information concerning the financial performance, business operations and
      prospects of Xoom.com presented at meetings of Xoom.com's board of
      directors, including among other things, Xoom.com's recent and historical
      stock and earnings performance;

    - the need of Xoom.com to enter into a strategic relationship to effectively
      compete in the Internet market;

    - the fact that the resulting holding company structure of NBCi following
      consummation of the transactions, will provide NBCi flexibility with
      respect to financing, state tax planning, employee compensation and
      acquisitions, minimize regulatory concerns and provide NBCi with
      additional protection from bankruptcy and other risks by having separate
      operating subsidiaries;

    - the fact that if NBC willfully fails to close the transactions
      contemplated by the contribution agreement after all of the conditions to
      closing have been satisfied, NBC will pay NBCi $475 million; and

    - the fact that the no-solicitation provision of the contribution agreement
      would permit the Xoom.com board of directors, in accordance with their
      fiduciary duties and the provisions of the contribution agreement, to:

     - entertain unsolicited offers,

     - provide information to such offerors, and

     - terminate the merger agreement and contribution agreement to enter into
       an agreement for such proposal if it were more favorable than the
       transactions contemplated by the merger agreement and the contribution
       agreement, and that the cost to Xoom.com in doing so would be capped at
       4% of Xoom.com's market value.

    Based on information with respect to the financial condition, results of
operations, cash flow, business and prospects of Xoom.com on both a stand-alone
basis and as compared with those available in combination with NBCi, the board
of directors of Xoom.com determined that the Xoom.com stockholders would benefit
substantially from the transactions. Such benefits would consist of:

    - the ability of the Xoom.com stockholders to own an interest in NBCi and
      thereby benefit from the enhanced prospects of NBCi in terms of enhanced
      financial and operational resources and flexibility and larger audience;

    - the combination of Xoom.com, SNAP and the NBC contributed Internet
      businesses will result in a larger company, with more members, users,
      products and services, which should enable NBCi to compete more
      effectively in the Internet market where size is becoming an important
      competitive factor;

    - the combination of complementary skills and experience of NBC, Xoom.com
      and SNAP;

    - NBCi's enhanced ability to take advantage of future strategic
      opportunities;

    - the value of NBC's name and trademarks;

    - the license to use NBC's name and brand with the Internet properties of
      NBCi;

                                       51
<PAGE>
    - the belief that merger should allow NBCi to meet the challenges of the
      increasingly competitive environment in the Internet market more
      effectively than Xoom.com could on its own; and

    - the expected tax and accounting treatment of the Xoom.com merger.

    The Xoom.com board of directors also considered a number of potentially
negative factors in its deliberations concerning the transactions, including:

    - that the closing of the transactions contemplated by the contribution
      agreement is not a condition to the closing of the transactions
      contemplated by the merger agreement and that, should the transactions
      under the merger agreement close but not the transactions under the
      contribution agreement, many of the perceived benefits of the Xoom.com
      merger may not occur;

    - the possibility of management and employee disruption associated with the
      transactions and the implications of disruptive aspects of the
      transactions on retaining key technical and management personnel;

    - the risks associated with obtaining necessary regulatory and stockholder
      approvals of the transactions;

    - the possibility that the transactions and the resulting relationship with
      SNAP and NBC might adversely affect Xoom.com's relationship with its
      customers, including other large media companies;

    - the risk that the potential benefits of the transactions might not be
      realized;

    - the relative complexity of the several transactions contemplated by the
      merger agreement, the contribution agreement and the related agreements;

    - that the option agreement, if exercisable, would eliminate the ability of
      a third party acquiror to account for an acquisition of Xoom.com using the
      pooling of interest accounting treatment, which could reduce the number of
      potential acquirors;

    - the increased resources that may be required to manage the larger
      operations of the combined companies, with a substantially increased
      employee base in diverse geographic locations; and

    - the other risks described under "Risk Factors."

    The Xoom.com board of directors concluded, however, that the potential
benefits of the transactions to Xoom.com and its stockholders outweighed the
risks associated with the foregoing factors.

    At its meeting on June 11, 1999, the board of directors of Xoom.com approved
the terms of the stock purchase agreement, the registration rights agreement and
the amended and restated agreement and plan of contribution, investment and
merger. In reaching this conclusion, the board of directors of Xoom.com, with
the assistance of its financial and legal advisors, considered and analyzed the
equity investment and the restructuring and determined that the restructuring
did not adversely affect the potential benefits of the transactions to Xoom.com
and its stockholders.

    At its meeting on July 7, 1999, the board of directors of Xoom.com approved
the terms of the contribution agreement and directed that the contribution
agreement be submitted for consideration by the Xoom.com stockholders. The board
of directors' approval was subject to confirmation from Bear Stearns that its
opinion rendered on May 9, 1999 remained in full force and effect and was
unaffected by the second restructuring proposal, which confirmation was received
on July 8, 1999. In reaching this conclusion, the board of directors of Xoom.com
with the assistance of its financial and legal advisors, considered and analyzed
the second restructuring and determined that the second restructuring did not
adversely affect the potential benefits of the transactions to Xoom.com or its
stockholders.

    At its meeting on October 18, 1999, the board of directors approved the
terms of the amendments to the merger agreement and the contribution agreement
and directed that such agreements, as amended, be submitted for consideration by
the Xoom.com stockholders. In reaching this conclusion,

                                       52
<PAGE>
the board of directors of Xoom.com, with the assistance of its financial and
legal advisers, considered and analyzed the proposed amendments and determined
such amendments did not adversely affect the potential benefits of the
transactions to Xoom.com or its stockholders.

    The foregoing discussion of the information and factors considered by the
Xoom.com board of directors in connection with its evaluation of the
transactions contemplated by the merger agreement, the contribution agreement
and the related agreements is not intended to be exhaustive but is intended to
include the material factors considered by the directors.

    FOR THE REASONS DESCRIBED ABOVE, THE XOOM.COM BOARD OF DIRECTORS RECOMMENDS
THAT THE HOLDERS OF XOOM.COM COMMON STOCK VOTE "FOR" ADOPTION OF THE MERGER
AGREEMENT AND ALSO VOTE "FOR" XOOM.COM'S ADOPTION OF THE CONTRIBUTION AGREEMENT.

    In considering the recommendation of the board of directors of Xoom.com with
respect to adopting the merger agreement and Xoom.com adopting the contribution
agreement, Xoom.com stockholders should be aware that the executive officers and
directors of Xoom.com have interests in the proposed transactions that are
different from and in addition to the interests of Xoom.com stockholders
generally. The Xoom.com board of directors was aware of these interests and
considered them in approving the merger agreement and the contribution agreement
and the transactions contemplated thereby. These interests are discussed on page
68 of this proxy statement/prospectus.

OPINION OF BEAR STEARNS

    Xoom.com engaged Bear Stearns as its financial advisor based on Bear
Stearns' experience and expertise in the merger and acquisition advisory
business. Bear Stearns is an internationally recognized investment banking firm
that has substantial experience in transactions similar to the proposed
transactions. Bear Stearns, as part of its investment banking business, is
continuously engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for corporate and other purposes.

    At the May 9, 1999 meeting of the Xoom.com board of directors, Bear Stearns
delivered its oral opinion, subsequently confirmed in a writing dated May 9,
1999, to the effect that, as of the date thereof, and subject to the
assumptions, qualifications and limitations set forth therein, after issuance of
NBCi shares to Xoom.com stockholders in the merger of Xenon 3 with Xoom.com, (a)
the aggregate issuance of NBCi shares to NBC and CNET in the transactions
contemplated by the merger agreement and the contribution agreement, taken
together, both before and after conversion of the NBCi convertible notes, in
exchange for the aggregate contribution of SNAP and the NBC contributed Internet
businesses, and (b) the issuance of NBCi shares to CNET in the transactions
contemplated by the merger agreement, if the transactions contemplated by the
contribution agreement are not consummated, in exchange for CNET's contribution
of its equity interests in SNAP, were fair, from a financial point of view, to
Xoom.com and its stockholders. On June 11, 1999, Bear Stearns confirmed that its
opinion remained in full force and effect and was unaffected by the equity
investment and restructuring entered into as of June 11, 1999. On July 8, 1999,
Bear Stearns confirmed that its opinion remained in full force and effect and
was unaffected by the second restructuring entered into as of July 8, 1999.
Prior to the meeting of the board of directors of Xoom.com on October 18, 1999,
Bear Stearns confirmed that its opinion remained in full force and effect and
was unaffected by the amendments to the merger agreement and contribution
agreement entered into as of October 20, 1999.

    The full text of the opinion, which sets forth the assumptions made, matters
considered and qualifications and limitations on the review undertaken by Bear
Stearns, is incorporated herein by reference. THE SUMMARY OF THE BEAR STEARNS
OPINION SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF THE OPINION WHICH IS ATTACHED AS APPENDIX C-1 TO THIS PROXY STATEMENT/
PROSPECTUS. BEAR STEARNS HAS CONSENTED TO THE INCLUSION OF ITS OPINION IN THIS
PROXY STATEMENT/ PROSPECTUS. Xoom.com shareholders are urged to read carefully

In reading the discussion of the fairness opinion set forth below, Xoom.com
stockholders should be aware that the Bear Stearns opinion:

    - was provided to the Xoom.com board of directors for its information and is
      to the effect that, after issuance of NBCi shares to Xoom.com stockholders
      in the merger of Xenon 3 with Xoom.com, (a) the aggregate issuance of NBCi
      shares to NBC and CNET in the transactions contemplated by the merger
      agreement and the contribution agreement, taken together, both before and
      after conversion of the NBCi convertible notes, in exchange for the
      aggregate contribution of SNAP and the NBC contributed Internet
      businesses, and (b) the issuance of NBCi shares to CNET in the
      transactions contemplated by the merger agreement, if the transactions
      contemplated by the contribution agreement are not consummated, in
      exchange for CNET's contribution of its equity interests in SNAP, were
      fair, from a financial point of view, to Xoom.com and its stockholders;

    - did not constitute a recommendation to the Xoom.com board of directors in
      connection with the proposed transactions;

    - did not address the merits of the underlying decision by Xoom.com to
      engage in the proposed transactions or the price or range of prices at
      which shares of Xoom.com common stock may trade subsequent to the
      announcement or consummation of the proposed transactions; and

    - does not constitute a recommendation to any holder of Xoom.com common
      stock as to how such shareholder should vote on the proposed transactions,
      or any matter related thereto.

    Although Bear Stearns was engaged to provide a fairness opinion to the board
of directors of Xoom.com, the financial terms in the proposed transactions were
determined by NBC, CNET and Xoom.com through arms-length negotiations. Bear
Stearns provided advice to Xoom.com during the course of such negotiations.
Xoom.com did not provide specific instructions to, or place any limitations on,
Bear Stearns with respect to the procedures to be followed or factors to be
considered by it in performing its analyses or providing its opinion.

    PREPARATION OF BEAR STEARNS OPINION

    In arriving at its opinion, Bear Stearns, among other things:

    - reviewed drafts of the agreement and plan of contribution and merger, the
      agreement and plan of contribution, investment and merger and other
      transaction documents;

    - reviewed Xoom.com's Annual Report to Shareholders and Annual Report on
      Form 10-K for the year ended December 31, 1998;

    - reviewed operating and financial information, including projections
      provided to Bear Stearns by the management of Xoom.com relating to
      Xoom.com's business and prospects;

    - met with members of Xoom.com's senior management to discuss its
      operations, historical financial statements and future prospects;

    - reviewed the historical prices and trading volume of Xoom.com common
      stock;

    - reviewed the trading activity of various Internet companies, including
      those which Bear Stearns deemed generally comparable to Xoom.com;

    - reviewed operating and financial information, including projections,
      provided to Bear Stearns by the management of Xoom.com relating to the NBC
      contributed Internet businesses and SNAP;

    - met with members of the senior management of NBC to discuss the
      operations, historical financial statements, projections and future
      prospects relating to SNAP and the NBC contributed Internet businesses;

    - reviewed publicly available financial data, stock market performance data
      and valuation parameters of companies which Bear Stearns deemed generally
      comparable to Xoom.com, to the

                                       54
<PAGE>
      businesses proposed to be acquired in the proposed transactions and to the
      combined company on a pro forma basis giving effect to the proposed
      transactions;

    - reviewed the terms of recent acquisitions of companies which Bear Stearns
      deemed generally comparable to the proposed transactions; and

    - conducted such other studies, analyses, inquiries and investigations as
      Bear Stearns deemed appropriate.

    In preparing its opinion, Bear Stearns relied upon and assumed, without
independent verification, the accuracy and completeness of all financial and
other projections provided to it by Xoom.com, SNAP and NBC. With respect to the
projected financial results provided to Bear Stearns, Bear Stearns assumed that
they have been reasonably prepared on bases reflecting the best currently
available estimates and judgments of the senior managements of Xoom.com, SNAP
and NBC as to the expected future performance of Xoom.com, SNAP and the NBC
contributed Internet businesses, respectively. Bear Stearns did not assume any
responsibility for the independent verification of any such information or of
the projections provided to Bear Stearns, and relied upon the assurances of the
senior managements of Xoom.com, Snap.com and NBC, respectively, that they were
unaware of any facts that would make the information or projections provided to
Bear Stearns incomplete or misleading.

    In arriving at its opinion, Bear Stearns did not perform or obtain any
independent appraisal of the assets or liabilities of Xoom.com, SNAP or the NBC
contributed Internet businesses, nor was it furnished with any such appraisals.
The Bear Stearns opinion is necessarily based on economic, market and other
conditions, and the information made available to Bear Stearns, as of the date
of its opinion. In addition, Bear Stearns recognized that the market prices for
Internet related companies such as Xoom.com have been the subject of significant
speculation and movement in recent months and the Bear Stearns' opinion was not
intended to predict or otherwise guarantee the trading prices of Xoom.com
following the announcement or consummation of the proposed transactions.

    Bear Stearns was initially engaged to explore strategic alternatives for
Xoom.com. After Xoom.com and NBC entered into a non-solicitation and
confidentiality agreement on April 15, 1999, Bear Stearns was requested to
prepare its opinion in connection with the proposed transactions involving NBC.
At this time, Bear Stearns was directed not to and did not seek or pursue
alternative transactions to the proposed transactions involving NBC, including
the possible sale of Xoom.com as an entirety. Although upon the consummation of
the transactions contemplated by the merger agreement and the contribution
agreement, NBC and its subsidiaries will own only approximately 47.3% of the
common stock of NBCi, in its capacity as financial advisor to Xoom.com, Bear
Stearns conservatively assumed, consistent with Delaware law, solely for
purposes of rendering its fairness opinion, that this ownership interest should
be viewed as a change of control transaction for purposes of evaluating whether,
after issuance of NBCi shares to Xoom.com stockholders in the merger of Xenon 3
with Xoom.com, (a) the aggregate issuance of NBCi shares to NBC and CNET in the
transactions contemplated by the merger agreement and the contribution
agreement, taken together, both before and after conversion of the NBCi
convertible notes, in exchange for the aggregate contribution of SNAP and the
NBC contributed Internet businesses, and (b) the issuance of NBCi shares to CNET
in the transactions contemplated by the merger agreement, if the transactions
contemplated by the contribution agreement are not consummated, in exchange for
CNET's contribution of its equity interests in SNAP, were fair, from a financial
point of view, to Xoom.com and its stockholders.

    In rendering its opinion, Bear Stearns did not address whether and under
what circumstances any third party interest in Xoom.com may arise as a result of
entering into the agreements related to the transactions. In addition, the
opinion did not address or make any assumptions with respect to the accounting
treatment applicable to the proposed transactions to each of Xoom.com, CNET and
NBC.

    FINANCIAL ANALYSIS OF BEAR STEARNS

    The following is a brief summary of the material valuation, financial and
comparative analyses underlying the presentation by Bear Stearns to the Xoom.com
board of directors in connection with the rendering of the Bear Stearns opinion.
Such summary does not purport to be a complete description of the analyses
underlying the Bear Stearns opinion and is qualified in its entirety by
reference to the full text of the Bear Stearns opinion, but does summarize the
material analyses underlying the Bear Stearns opinion.

    In performing its analysis, Bear Stearns made numerous assumptions with
respect to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Bear Stearns, NBC, CNET, SNAP and Xoom.com. Any estimates contained in the
analysis performed by Bear Stearns is not necessarily indicative of actual
values or future results, which may be significantly more or less favorable than
suggested by such analysis. Additionally, estimates of the value of businesses
or securities do not purport to be appraisals or to reflect the prices at which
such businesses or securities may actually be sold. Accordingly, such analyses
and estimates are inherently subject to substantial uncertainty. In addition, as
described above, the Bear Stearns opinion was among several factors taken into
consideration by the Xoom.com board of directors in making its determination to
approve the merger agreement, the contribution agreement and the proposed
transactions.

    TRANSACTION VALUE.  In conducting a transaction value analysis, Bear Stearns
arrived at a range of enterprise values for the combined company,
post-synergies, using the following valuation methodologies:

    - discounted cash flow analysis,

    - comparable company analysis, and

    - comparable acquisition analysis.

The range of enterprise values for each of the different valuation methodologies
is indicated in the table below.

<TABLE>
<CAPTION>
VALUATION METHOD                                                  ENTERPRISE VALUE RANGE
- ----------------------------------------------------------  ----------------------------------
                                                                       ($ MILLIONS)
<S>                                                         <C>                    <C>
Discounted Cash Flow Analysis.............................        $   4,500         $   5,000
Comparable Company Analysis...............................            4,250             4,750
Comparable Acquisition Analysis...........................            4,250             5,000
Summary Reference Range...................................            4,250             4,750
</TABLE>

    The summary reference range represents a single range of values summarizing
the values implied by the three analyses, but does not necessarily represent an
average of the three analyses. The range is based on Bear Stearns' judgment
regarding a reasonable range that may be implied by the various valuation
methods, with a preference for conservative values and values that will narrow
the range rather than expand the range to the maximum range that the data may
support. As a result, Bear Stearns determined that a reasonable summary
reference range for this transaction would be the range implied by the estimates
at the lower end of the ranges resulting from the three analyses.

        DISCOUNTED CASH FLOW. Using the financial projections provided by
    Xoom.com, SNAP and NBC for the combined company through year 2002, Bear
Stearns calculated a range of enterprise values for the combined company using a
discounted cash flow valuation method. A discounted cash flow analysis provides
insight into the intrinsic value of a business based on the net present value of
the projected cash flows net of gross investment anticipated to be generated by
the assets of the business. The discounted cash flow analysis assumed, solely
for purposes of this analysis, a terminal value multiple of 2002 revenues
ranging from 12.0x to 14.0x because comparable companies typically have
multiples in such range. Bear Stearns determined that a multiple of 12.0x to
13.0x was most

                                       56
<PAGE>
appropriate, and weighted such data points more heavily, because at the time of
the Bear Stearns' analysis, Xoom.com traded at approximately 13.2x year 2000
estimated revenues. Additionally, Bear Stearns' valuation of the combined
company based on a comparable company analysis implied a multiple of 12.2x to
13.6x year 2000 estimated revenues. The discounted cash flow analysis also
assumed a discount rate for the combined company ranging from 17% to 20% because
analyst coverage of comparable companies indicated that research analysts
typically use discount rates of approximately 15% for more established Internet
companies, and discount rates of approximately 20% for start-up Internet
companies. Bear Stearns determined that a discount rate of 17% to 18% was most
appropriate, and weighted such data points more heavily, because Bear Stearns'
weighted average cost of capital analysis indicated a range of 17% to 18%. Based
on such assumptions, Bear Stearns calculated a range of enterprise values for
the combined company of $4,500 to $5,000 million.

        COMPARABLE COMPANY ANALYSIS. Bear Stearns compared operating, financial,
    trading and valuation information for the operations of the combined company
to publicly available operating, financial, trading and valuation information of
twenty selected portal/communities, content and e-commerce companies which, in
Bear Stearns' judgment, were comparable to the operations of the combined
company for purposes of this analysis. A comparable company analysis reviews a
business' operating performance and outlook relative to a group of peer
companies to determine an implied unaffected market trading value. Bear Stearns
used the following metrics to arrive at its valuation range:

    - enterprise value as a multiple of calendar year 1999 and 2000 projected
      revenues,

    - enterprise value as a multiple of unique visitors, and

    - enterprise value as a multiple of daily page views.

Because portal, content providers and e-commerce firms utilizing the Internet
are relatively new, generally accepted metrics for performing a comparable
company analysis have not yet fully evolved. Bear Stearns used these metrics
because in Bear Stearns' judgment such metrics are reasonable for portal,
content providers and e-commerce firms and such metrics are beginning to be
widely used in the internet sector. In performing the comparable company
analysis, Bear Stearns did not weight any one metric more heavily than any
other. The companies included:

                          - About.com
</TABLE>

    Bear Stearns noted that none of the comparable companies were exactly
identical to the combined company and that, accordingly, any analysis of
comparable companies necessarily involved complex consideration and judgments
concerning differences in financial and operating characteristics and other
factors that would necessarily affect the relative trading and acquisition
values.

    In the instances where Bear Stearns determined that the applicable
comparable company did not fit well with the combined company's profile for a
particular metric, Bear Stearns weighted the resulting data less heavily than
the data obtained for comparable companies which more closely match the combined
company's profile. Therefore, Bear Stearns did not necessarily weight each
comparable company equally. Specifically, the combined company has
characteristics of a portal, a content provider and an e-commerce player.
However, Bear Stearns determined that the combined company is unlike other
comparable e-commerce companies based on the assumption that the combined
company would

                                       57
<PAGE>
not have to pay for its traffic through banner placements on other Web sites, as
it would be able to generate its own traffic. In addition, when comparing the
combined company to the portals/ communities sector, Bear Stearns determined
that the portal portion of the combined company should be valued at a discount
to multiples of other portals that have a larger market share or are market
leaders. Also, when comparing the combined company with broadband content
providers, Bear Stearns estimated that the broadband content portion of the
combined company should be valued at a discount to multiples of other broadband
content providers that may deliver content from various television program
providers, because the combined company's television programming will be limited
by the combined company's relationship with NBC.

    In general, Bear Stearns placed less emphasis on certain of the comparable
companies which are market leaders since the combined company will be newly
formed and have no operating history. In addition, some of the comparable
companies are on a steeper growth trajectory and thus justify a greater multiple
while others have less growth potential than the combined company and thus will
not support a multiple as high as that of the combined company.

    In short, the comparable companies are comparable in some respects, but none
are comparable in all respects. Bear Stearns examined each comparable company to
determine its relevance to the combined company and weighted such comparable
companies appropriately. The examples described in the two paragraphs above are
examples only; Bear Stearns conducted other similar analysis for all the
comparable companies. Based on this analysis, Bear Stearns calculated the
enterprise value of the combined company to be in the range of $4,250 to $4,750
million.

        COMPARABLE ACQUISITIONS ANALYSIS. Bear Stearns reviewed and analyzed the
    publicly available financial terms of four selected acquisition transactions
in the Internet sector which, in Bear Stearns' judgment, were reasonably
comparable to the proposed transactions, and compared the financial terms of
such transactions to those of the proposed transactions. A comparable
acquisition analysis provides a valuation range based upon financial information
of companies which have been acquired in selected recent acquisitions and which
are in the same or similar industries as the business being evaluated. The four
transactions included:

    - Disney's investment in Infoseek

    - USA Network's proposed acquisition of Lycos

    - @Home Network's acquisition of Excite

    - Yahoo!'s acquisition of GeoCities

    Bear Stearns reviewed the prices paid in such transactions and analyzed
various operating and financial information and imputed valuation multiples and
ratios. Specifically, Bear Stearns reviewed the target's enterprise value as a
multiple of the one-year and two-year forward revenues at the time of the
announcement of each transaction. Bear Stearns' analysis of the comparable
acquisitions indicated an enterprise value range of the combined company of
$4,250 to $5,000 million.

    Bear Stearns also noted that none of the comparable transactions were
identical to the proposed transactions and that, accordingly, any analysis of
the comparable acquisitions necessarily involved complex consideration and
judgments concerning the differences in financial and operating characteristics
and other factors that would necessarily affect the acquisition values.

    VALUATION OF SNAP AND NBC'S CONTRIBUTED INTERNET ASSETS.  Bear Stearns also
valued each of SNAP, NBC.com, NBC-IN.com, VideoSeeker and a 10% interest in
CNBC.com using comparable company analyses and comparable acquisition analyses.
With respect to the 10% interest in CNBC.com, Bear Stearns also performed a
discounted cash flow analysis. The discounted cash flow analysis assumed, solely
for purposes of the analysis of CNBC.com, a terminal value multiple of 20.0x to
26.0x 2002 revenues and a discount rate range between 20% and 26%. Bear Stearns
valued the NBC brand and other intangibles provided by NBC by discounting back
an assumed royalty stream that Xoom.com

                                       58
<PAGE>
would have to pay NBC for the use of the NBC brand. The royalty stream was
estimated at 6% to 8% of the difference between the combined company's revenue
and Xoom.com's stand-alone revenue, and discounted using a cost of capital of
18%.

    Bear Stearns used the following acquisition transactions in the Internet
sector as comparables for the proposed acquisition of each of SNAP, NBC.com,
NBC-IN.com and the 10% equity interest in CNBC.com:

    - Disney's investment in Infoseek,

    - USA Networks' proposed acquisition of Lycos,

    - @Home Network's acquisition of Excite, and

    - Yahoo!'s acquisition of GeoCities.

Bear Stearns used Yahoo!'s acquisition of Broadcast.com as a comparable for the
proposed acquisition of VideoSeeker.

    Bear Stearns used the following comparable companies for the operations of
SNAP, NBC.com, NBC-IN.com, VideoSeeker and CNBC.com.

</TABLE>

    Based on these analyses, Bear Stearns determined a range of enterprise
values for the NBC contributed Internet businesses and SNAP, of approximately
$2,863 to $3,433 million. Bear Stearns concluded that the enterprise value of
Xoom.com represents between 23.9% and 27.3% of the enterprise value of the
combined company indicated by the summary reference range of $3,940 to $4,510
million. As Xoom.com will receive over 33.3% of the combined company, under this
valuation method Xoom.com will receive a greater proportion of the combined
company than its proportion of the aggregate contribution to the combined
company.

    HAS/GETS ANALYSIS.  Bear Stearns also conducted a per share "Has/Gets"
analysis based on the May 6, 1999 closing share price of Xoom.com common stock
of $68.00 per share. A "Has/Gets" analysis is a mathematical comparison of what
shareholders have prior to consummation of a

                                       59
<PAGE>
transaction (and thus will have absent consummation of such transaction) to what
shareholders will get upon consummation of such transaction.

    Based on the May 6, 1999 stock price, the equity value of Xoom.com as of
such date was approximately $1,312 million. After adjusting for cash, option
proceeds, indebtedness, minority interests in subsidiaries and preferred stock,
Bear Stearns calculated the May 6, 1999 enterprise value of Xoom.com to be
approximately $1,077 million.

    Next, Bear Stearns calculated the value of the combined company,
pre-synergies, by adding in the estimated range of enterprise values of the NBC
contributed Internet businesses. The calculation resulted in a range of
enterprise values for the combined company of $3,940 to $4,510 million. If
Xoom.com's stockholders received approximately 33.3% of the combined company,
they would receive a value of $1,313 to $1,503 million. Bear Stearns also noted
that, based on the post-synergies enterprise value range of $4,250 to $4,750
million for the combined company, Xoom.com's stockholders would receive $1,417
to $1,583 million, assuming Xoom.com's stockholders received approximately 33.3%
of such value.

Xoom.com's approximately 33.3% of the Combined Company,
  Pre-Synergies.............................................  $1,313.3 -- $1,503.3
Value of the Combined Company, Post-Synergies...............  $4,250.0 -- $4,750.0
Xoom.com's approximately 33.3% of the Combined Company,
  Post-Synergies............................................  $1,416.7 -- $1,583.3
</TABLE>

    Although, for purposes of this analysis, Bear Stearns assumed that
Xoom.com's stockholders would receive approximately 33.3% of the value of the
combined company, Xoom.com's stockholders will actually receive approximately
39% of the equity of the combined company, before conversion of the NBCi
convertible notes, Bear Stearns concluded that the value range of Xoom.com's
interest in the combined company both pre-synergies ($1,313.3 to $1,503.3
million), and post-synergies ($1,416.7 to $1,583.3 million) exceeds the current
enterprise value of Xoom.com absent consummation of the transactions ($1,077.0
million).

    OTHER ANALYSES.  Bear Stearns conducted such other analyses as it deemed
necessary, including reviewing historical and projected financial and operating
data for Xoom.com, the NBC contributed Internet assets and SNAP and selected
investment research reports on each of the entities, including information
pertaining to the estimated revenues and cash flow for each of the entities and
assessing future acquisition and growth opportunities for each of the companies.

    The preparation of a fairness opinion is a complex process and involves
various judgments and determinations as to the most appropriate and relevant
assumptions and financial analyses and the application of these methods to the
particular circumstances involved. Such an opinion is therefore not readily
susceptible to partial analysis or summary description, and taking portions of
the analyses set out above, without considering the analysis as a whole, would,
in the view of Bear Stearns, create an incomplete and misleading picture of the
processes underlying the analyses considered in rendering the Bear Stearns
opinion. Bear Stearns did not form an opinion as to whether any individual
analysis or factor, positive or negative, considered in isolation, supported or
failed to support the Bear Stearns opinion. In arriving at its opinion, Bear
Stearns considered the results of its separate analyses and did not attribute
particular weight to any one analysis or factor considered by Bear Stearns. The
analyses performed by Bear Stearns, particularly those based on estimates and
projections, are not necessarily indicative of actual values or actual future
results, which may be significantly more or less favorable than suggested by
such analyses. Such analyses were prepared solely as part of the Bear Stearns
analysis of the fairness to Xoom.com and its stockholders, from a financial
point of view, of the financial terms of the transactions.

    FEE ARRANGEMENTS

    Pursuant to the terms of its engagement letter with Bear Stearns, Xoom.com
has agreed to pay Bear Stearns a total fee equal to $1.0 million, plus 0.75% of
the greater of the total fair market value of all cash, equity securities,
property, debt or other obligations obtained by Xoom.com's holders of common
stock as of May 9, 1999 or on the date the transactions contemplated by the
merger agreement are consummated. On May 9, 1999, the amount of the fee on this
basis would have been approximately $12 million in the aggregate. $2.5 million
of Bear Stearns' fee became payable to Bear Stearns upon the delivery of its
opinion and the remainder of which will become payable upon consummation of the
proposed transactions. In addition, Xoom.com has agreed to reimburse Bear
Stearns for all reasonable out-of-pocket expenses incurred by it in connection
with the proposed transactions, including reasonable fees and disbursements of
its legal counsel. Xoom.com has also agreed to indemnify Bear Stearns against
specific liabilities in connection with its engagement, including liabilities
under the federal securities laws.

    Bear Stearns has previously rendered investment banking and financial
advisory services to Xoom.com. Bear Stearns served as Xoom.com's financial
advisor in connection with its IPO and follow-on equity offerings, for which it
received customary compensation. In the ordinary course of its business, Bear
Stearns may actively trade the securities of Xoom.com, General Electric, the
publicly-traded parent of NBC, and/or CNET for its own account and for accounts
of its customers and, accordingly, Bear Stearns may at any time hold a long or
short position in such securities. Bear Stearns may provide financial advisory
and financing services to the combined company and/or its affiliates and may
receive fees for the rendering of such services.

OPINION OF HAMBRECHT & QUIST

    Xoom.com engaged Hambrecht & Quist to act as its financial advisor in
connection with the proposed transactions solely for the purpose of issuing an
opinion to the effect that, after issuance of NBCi shares to Xoom.com
stockholders in the merger of Xenon 3 with Xoom.com, the aggregate issuance of
NBCi shares to NBC and CNET in the transactions contemplated by the merger
agreement and the contribution agreement, taken together, both before and after
conversion of the NBCi convertible notes, in exchange for the aggregate
contribution of SNAP and the NBC contributed Internet businesses, was fair, from
a financial point of view, to Xoom.com and its stockholders. Hambrecht & Quist
was selected by the Xoom.com board of directors based on Hambrecht & Quist's
qualifications, expertise and reputation, as well as Hambrecht & Quist's
historic investment banking relationship and familiarity with Xoom.com.
Hambrecht & Quist rendered its oral opinion, subsequently confirmed in writing,
on May 9, 1999 to the Xoom.com board of directors that, as of such date, the
aggregate issuance of NBCi shares to NBC and CNET in the transactions
contemplated by the merger agreement and the contribution agreement, taken
together, both before and after conversion of the NBCi convertible notes, in
exchange for the aggregate contribution of SNAP and the NBC contributed Internet
businesses was fair, from a financial point of view, to Xoom.com and its
stockholders. On June 11, 1999, Hambrecht & Quist confirmed that its opinion
remained in full force and effect and was unaffected by the equity investment
and restructuring entered into as of June 11, 1999. On July 7, 1999, Hambrecht &
Quist confirmed that its opinion remained in full force and effect and was
unaffected by the second restructuring entered into as of July 8, 1999. Prior to
the meeting of the board of directors of Xoom.com on October 18, 1999, Hambrecht
& Quist confirmed that its opinion remained in full force and effect and was
unaffected by the amendments to the merger agreement and contribution agreement
entered into as of October 20, 1999.

    THE FULL TEXT OF THE OPINION DELIVERED BY HAMBRECHT & QUIST TO THE XOOM.COM
BOARD OF DIRECTORS, DATED MAY 9, 1999, WHICH SETS FORTH THE ASSUMPTIONS MADE,
GENERAL PROCEDURES FOLLOWED, MATTERS CONSIDERED, AND LIMITATIONS ON THE SCOPE OF
REVIEW UNDERTAKEN BY HAMBRECHT & QUIST IN RENDERING ITS OPINION, IS ATTACHED AS
APPENDIX C-2 TO THIS PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY
REFERENCE. THE HAMBRECHT & QUIST OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO
ANY XOOM.COM

<PAGE>
STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE WITH RESPECT TO THE MERGER
AGREEMENT AND THE CONTRIBUTION AGREEMENT. THE SUMMARY OF THE HAMBRECHT & QUIST
OPINION SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL
TEXT OF SUCH FAIRNESS OPINION ATTACHED HERETO AS APPENDIX C-2. XOOM.COM
STOCKHOLDERS ARE URGED TO READ THE OPINION CAREFULLY IN ITS ENTIRETY.

    In reviewing the proposed transactions, and in arriving at its opinion,
Hambrecht & Quist, among other things:

    - Reviewed the financial statements of SNAP, NBC-IN.com, NBC.com,
      VideoSeeker and CNBC.com for recent years and interim periods to date and
      other relevant financial and operating data of SNAP and the NBC
      contributed Internet businesses made available to Hambrecht & Quist from
      the internal records of SNAP and the NBC contributed Internet businesses;

    - Reviewed internal financial and operating information, including
      projections, related to SNAP and the NBC contributed Internet businesses,
      prepared by management of Xoom.com;

    - Discussed the business, financial condition and prospects of SNAP and the
      NBC contributed Internet businesses with members of senior management of
      SNAP and the NBC contributed Internet businesses;

    - Reviewed Xoom.com's publicly available financial statements for recent
      years and interim periods to date and other relevant financial and
      operating data of Xoom.com made available to Hambrecht & Quist from
      published sources and from the internal records of Xoom.com;

    - Discussed Xoom.com's business, financial condition and prospects with
      members of senior management of Xoom.com;

    - Reviewed the recent reported prices and trading activity for the common
      stock of Xoom.com and compared such information and financial information
      for SNAP, the NBC contributed Internet businesses and Xoom.com with
      similar information for other companies engaged in businesses Hambrecht &
      Quist considered generally comparable;

    - Reviewed the financial terms, to the extent publicly available, of
      comparable merger and acquisition transactions;

    - Reviewed drafts of the agreement and plan of contribution and merger and
      the agreement and plan of contribution, investment and merger, each dated
      as of May 6, 1999 and other transaction documents; and

    - Performed such other analyses and examinations and considered such other
      information, financial studies, analyses and investigations and financial,
      economic and market data as Hambrecht & Quist deemed relevant.

    Hambrecht & Quist did not independently verify any of the information
concerning Xoom.com, SNAP or the NBC contributed Internet businesses considered
in connection with its review of the proposed transactions and, for purposes of
its opinion, Hambrecht & Quist assumed and relied upon the accuracy and
completeness of all such information. In connection with its opinion, Hambrecht
& Quist did not prepare or obtain any independent valuation or appraisal of any
of the assets or liabilities of Xoom.com, SNAP or the NBC contributed Internet
businesses, nor did it conduct a physical inspection of the properties and
facilities of Xoom.com, SNAP or the NBC contributed Internet businesses. With
respect to the financial forecasts and projections used in its analysis,
Hambrecht & Quist assumed that they reflected the best currently available
estimates and judgments of the expected future financial performance of
Xoom.com, SNAP and the NBC contributed Internet businesses. For the purposes of
its opinion, Hambrecht & Quist also assumed that none of Xoom.com, SNAP or the
NBC contributed Internet businesses was a party to any pending transactions,
including external recapitalizations or material merger discussions, other than
the proposed transactions and transactions in the ordinary course of conducting
their respective businesses. For purposes of its opinion,

                                       62
<PAGE>
Hambrecht & Quist assumed that the proposed transactions will be implemented on
a tax-free basis. Hambrecht & Quist's opinion is necessarily based upon market,
economic, financial and other conditions as they existed and can be evaluated as
of the date of the opinion and any subsequent change in such conditions would
require a reevaluation of such opinion.

    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the Hambrecht & Quist analyses set forth below does not purport to be a
complete description of the presentation by Hambrecht & Quist to the Xoom.com
board of directors, but does summarize the material analyses presented to the
Xoom.com board of directors. In arriving at its opinion, Hambrecht & Quist did
not attribute any particular weight to any analyses or factors considered by it,
but rather made qualitative judgments as to the significance and relevance of
each analysis and factor. Accordingly, Hambrecht & Quist believes that its
analyses and the summary set forth below must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or of the
following summary, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the
Hambrecht & Quist presentation to the Xoom.com board of directors and its
opinion. In performing its analyses, Hambrecht & Quist made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of Xoom.com, SNAP and
the NBC contributed Internet businesses. The analyses performed by Hambrecht &
Quist and summarized below are not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses. Additionally, analyses relating to the values of
businesses do not purport to be appraisals or to reflect the prices at which
businesses actually may be acquired.

    In performing its analyses, Hambrecht & Quist used published Hambrecht &
Quist research estimates of calendar year 1999 and 2000 financial performance by
Xoom.com and used estimates by Xoom.com management of calendar year 1999 and
2000 financial performance by SNAP and the NBC contributed Internet businesses.

    The following is a brief summary of the material financial analyses
performed by Hambrecht & Quist in connection with providing its written opinion
to the Xoom.com board of directors on May 9, 1999. In performing the various
financial analyses, Hambrecht & Quist valued the combined company assuming
consummation of the transactions contemplated by both the merger agreement and
the contribution agreement. Hambrecht & Quist did not value the intermediate
company formed pursuant to the merger agreement that existed immediately before
the transactions contemplated by the contribution agreement. The summary of
financial analyses includes information presented in tabular format. You should
read these tables together with the text of each summary.

    VALUATION ANALYSIS OF XOOM.COM

    ANALYSIS OF PUBLICLY TRADED COMPANIES COMPARABLE TO XOOM.COM.  This analysis
reviews a business' operating performance and outlook relative to a group of
peer companies to determine an implied value. Using Hambrecht & Quist research
and published Wall Street estimates, Hambrecht & Quist compared, among other
things, the equity values, enterprise values, revenues for the last twelve-month
period and projected revenues for calendar 1999 and calendar 2000 for Xoom.com
to corresponding measures for publicly traded Internet companies that Hambrecht
& Quist considered comparable to Xoom.com. Hambrecht & Quist used revenues when
making its comparisons because revenue valuations are generally accepted when
analyzing Internet companies which, in many cases, have not

                                       63
<PAGE>
achieved profitability. The Internet companies that Hambrecht & Quist considered
comparable to Xoom.com were:

- - GeoCities                          - iTurf
</TABLE>

    Hambrecht & Quist determined average revenue multiples for the comparable
companies. Applying such multiples for the comparable companies to projected
calendar 1999 and calendar 2000 revenues of Xoom.com resulted in the ranges of
implied equity values and enterprise values of Xoom.com set forth in the
following table:

</TABLE>

    These implied value ranges were compared to the ranges of implied equity
values for the portion of NBCi to be received by Xoom.com's stockholder's as
described in "Analysis of the Proposed Xoom.com Share of NBCi" below, ranging
from approximately $1,240 million to $1,759 million before conversion of the
NBCi convertible notes, to approximately $1,248 million to $1,720 million
assuming conversion of the NBCi convertible notes.

    ANALYSIS OF SELECTED TRANSACTIONS.  This analysis provides a valuation range
based upon financial information of companies which have been acquired in
selected recent acquisitions and which are in the same or similar industries as
the business being evaluated. Using Hambrecht & Quist research and published
Wall Street estimates, Hambrecht & Quist compared the proposed transactions with
selected mergers and acquisitions transactions. This analysis included seven
transactions involving companies in the Internet industry. The Internet
transactions that Hambrecht & Quist deemed comparable to the proposed
transactions were (listed as acquiror/target):

<TABLE>
<S>                                  <C>

- - @Home Network / Excite             - USWeb/ CKS Group
</TABLE>

    In examining these transactions, Hambrecht & Quist analyzed, among other
things, the multiples of offer prices to revenues for the last twelve-month
period and projected revenues for calendar 1999 for the acquired companies.
Applying the foregoing multiples to the revenues of Xoom.com for the last
twelve-month period and projected calendar 1999 revenues resulted in the ranges
of implied equity values and enterprise values of Xoom.com set forth in the
following table:

    These implied value ranges were compared to the ranges of implied equity
values for the portion of NBCi to be received by Xoom.com's stockholder's as
described in "Analysis of the Proposed Xoom.com Share of NBCi" below, ranging
from approximately $1,240 million to $1,759 million before conversion of the
NBCi convertible notes, to approximately $1,248 million to $1,720 million
assuming conversion of the NBCi convertible notes, which ranges Hambrecht &
Quist concluded to be at or above the implied range of Xoom.com on a stand-alone
basis.

Hambrecht & Quist determined average revenue multiples for the companies
considered comparable to SNAP and each of the NBC contributed Internet
businesses and applied these multiples to projected calendar 1999 and calendar
2000 revenues supplied by Xoom.com's management for SNAP and each of the NBC
contributed Internet businesses. Using the implied enterprise value and the
implied equity value of SNAP and each of the NBC contributed Internet businesses
and excluding any value associated with the advertising agreement between NBC
and NBCi, and the NBC note, which, at the time of Hambrecht & Quist's analysis
had an assumed value of $360 million, Hambrecht & Quist determined a range of
aggregate implied equity values of SNAP and the NBC contributed Internet
businesses taken together of $1,949 million to $2,770 million.

    VALUATION ANALYSIS OF NBCI

    ANALYSIS OF PUBLICLY TRADED COMPANIES COMPARABLE TO NBCI.  Using Hambrecht &
Quist research and published Wall Street estimates, Hambrecht & Quist compared,
among other things, the equity values, enterprise values, revenues for the last
twelve-month period and projected revenues for calendar 1999 and calendar 2000
for NBCi to corresponding measures for publicly traded Internet companies that
Hambrecht & Quist considered comparable to NBCi. Internet companies considered
comparable to NBCi were divided into two categories set forth below:

Hambrecht & Quist determined average equity values as multiples of revenue and
enterprise values as multiples of revenue for the comparable companies. All such
multiples were based on closing stock prices as of May 7, 1999. As set forth in
the following table, applying such multiples for the comparable companies to
projected calendar 1999 and calendar 2000 revenues of NBCi, based on Xoom.com
management estimates, excluding synergies, resulted in the following ranges of
implied equity values and enterprise values of NBCi, excluding any value
associated with the advertising agreement between NBC and NBCi, the NBCi cash,
the NBC note (which, at the time of Hambrecht & Quist's analysis had an assumed
value of $360 million) and the value of the interest in CNBC.com.

    ANALYSIS OF THE PROPOSED XOOM.COM SHARE OF NBCI.  Hambrecht & Quist
calculated the range of equity values attributable to the portion of NBCi to be
received by Xoom.com's stockholders in the proposed transaction by adjusting the
implied equity values calculated above for the advertising agreement between NBC
and NBCi, the NBCi cash, the NBC note, which, at the time of Hambrecht & Quist's
analysis had an assumed value of $360 million, and the value of the interest in
CNBC.com, and multiplying by the Xoom.com ownership stake in NBCi, both before
and after conversion of the NBCi convertible notes. Based on this analysis,
Hambrecht & Quist calculated a range of implied equity values for the portion of
NBCi to be received by Xoom.com's stockholders in the proposed transaction from
approximately $1,240 million to $1,759 million before conversion of the NBCi
convertible notes and from approximately $1,248 million to $1,720 million
assuming conversion of the NBCi convertible notes, which ranges Hambrecht &
Quist concluded to be at or above the implied ranges of Xoom.com on a
stand-alone basis as calculated in the "Analysis of Publicly Traded Companies
Comparable to Xoom.com".

    COMPARISON OF IMPLIED EQUITY VALUES

    Hambrecht & Quist analyzed the contribution of each of Xoom.com, SNAP and
the NBC contributed Internet businesses to the total implied equity value of the
combined company, both before and after the conversion of the NBCi convertible
notes. Hambrecht & Quist determined the equity value of NBCi by comparing
projected financial information for Xoom.com, SNAP and the NBC contributed
Internet assets to publicly traded companies comparable to such entities.
Hambrecht & Quist observed that, based on the implied equity values of Xoom.com
and NBCi, the implied range of aggregate percentage equity interests of the
Xoom.com stockholders in NBCi was between 42.0% and 33.8% before the conversion
of the NBCi convertible notes, and between 38.0% and 31.2% after the conversion
of the NBCi convertible notes. These figures were compared to the 36.6% equity
interest, 33.3% after conversion of the NBCi convertible notes, that Hambrecht &
Quist assumed that the Xoom.com stockholders would have received pursuant to the
merger agreement and the agreement and plan of contribution, investment and
merger entered into as of May 9, 1999, which figures Hambrecht & Quist concluded
to be within the respective implied ranges of aggregate percentage equity
interests stated above.

    No company or transaction used in the above analyses is identical to
Xoom.com or the proposed transactions. Accordingly, an analysis of the results
of the foregoing is not mathematical; rather it involves complex considerations
and judgments concerning differences in financial and operating characteristics
of the companies and other factors that could affect the public trading values
of the companies or company to which they are compared.

    The foregoing description of Hambrecht & Quist's opinion is qualified in its
entirety by reference to the full text of such opinion which is attached as
Appendix C-2 to this joint proxy statement/ prospectus.

    Hambrecht & Quist, as part of its investment banking services, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, strategic transactions, corporate restructurings,
negotiated underwritings, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
Hambrecht & Quist has acted as a financial advisor to the board of directors of
Xoom.com in connection with the transactions solely for the purpose of issuing
its fairness opinion.

    In the past, Hambrecht & Quist has provided investment banking and other
financial advisory services to Xoom.com and has received fees for rendering
these services, including serving as a co-manager in Xoom.com's April 9, 1999
international and U.S. secondary offering. In the ordinary course of business,
Hambrecht & Quist acts as a market maker and broker in the publicly traded
securities of Xoom.com and receives customary compensation in connection
therewith, and also provides research coverage for Xoom.com. In the ordinary
course of business, Hambrecht & Quist actively trades in the equity and
derivative securities of Xoom.com for its own account and for the accounts of
its customers and, accordingly, may at any time hold a long or short position in
such securities. Hambrecht & Quist may in the future provide investment banking
or other financial advisory services to Xoom, SNAP or the NBC contributed
Internet businesses.

    Pursuant to an engagement letter dated April 26, 1999, Xoom.com has agreed
to pay Hambrecht & Quist a fee of approximately $1.0 million in connection with
the delivery of the fairness opinion rendered on May 9, 1999. Xoom.com also has
agreed to reimburse Hambrecht & Quist for its reasonable out-of-pocket expenses
and to indemnify Hambrecht & Quist against specific liabilities, including
liabilities under the federal securities laws or relating to or arising out of
Hambrecht & Quist's engagement as financial advisor.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF XOOM.COM IN THE TRANSACTIONS

    GENERAL

    The executive officers and members of the Xoom.com board of directors have
interests in the transactions contemplated by the merger agreement and the
contribution agreement that are different from, or in addition to, the interests
of stockholders of Xoom.com generally. These include, among other things,
provisions in the merger agreement and the contribution agreement relating to
indemnification and the acceleration and/or payout of benefits under specified
agreements and employee benefit plans. The Xoom.com board of directors was aware
of these interests and considered them, among other matters, in approving the
merger agreement, the contribution agreement and the transactions contemplated
thereby.

    The merger agreement provides that NBCi will cause Xoom.com, as the
surviving corporation in the merger of Xenon 3 with Xoom.com, to assume and
honor in accordance with their terms specified compensation agreements, plans
and arrangements which existed prior to the execution of the merger agreement
between Xoom.com and any of its directors, officers or employees.

    INDEMNIFICATION AND INSURANCE

    The merger agreement provides that NBCi shall cause the surviving
corporation to indemnify each present and former director or officer of Xoom.com
or any of its subsidiaries, to the fullest extent permitted under Xoom.com's
certificate of incorporation, bylaws or applicable law, for liabilities for acts
or omissions occurring at or prior to the date of the Xoom.com merger. The
indemnification obligations include the payment of any costs, judgments,
settlements or attorneys' fees and providing advances of expenses. The merger
agreement also provides that NBCi shall cause the surviving corporation to
maintain Xoom.com's current directors' and officers' liability insurance
coverage on terms no less favorable than the policy currently in effect for six
years after the date of the Xoom.com merger, but the surviving corporation is
not obligated to pay for any annual premium more than 200% of the amount paid
for premiums by Xoom.com as of the date of the merger agreement.

    OPTIONS

    Pursuant to the merger agreement, all outstanding stock options granted
under the Xoom.com 1998 stock incentive plan (the "Option Plan," and each option
granted under the Option Plan, a "Plan Option") as well as all outstanding stock
options to acquire Xoom.com shares granted outside of the Option Plan (the
"Non-Plan Options") will, upon the closing of the merger agreement, be converted
into options to purchase an equal number of shares of NBCi on the same terms and
conditions as were applicable to such Plan Options and Non-Plan Options prior to
such conversion.

    Pursuant to the Option Plan, upon the occurrence of a corporate transaction,
each outstanding Plan Option would become vested with respect to 75% of the
unvested portion of such Plan Option, unless the Option Plan administrator
exercises its discretion to prevent such acceleration. As discussed on page 88,
Xoom.com has agreed to modify the accelerated vesting of the Plan Options. In
addition, under the terms of the option agreement evidencing each Non-Plan
Option (the "Non-Plan Option Agreement"), upon the occurrence of a corporate
transaction each outstanding Non-Plan Option would become vested with respect to
75% of the unvested portion of such Non-Plan Option and the remaining unvested
portion of such Non-Plan Option, as well as any vested portion of the Non-Plan
Option which is not in fact exercised prior to the consummation of the corporate
transaction, will expire upon the occurrence of the corporate transaction.

    The administrator of the Option Plan and Xoom.com's board of directors have
each determined that the closing of the contribution agreement will constitute a
corporate transaction for purposes of the Option Plan and the Non-Plan Option
Agreement, respectively. As contemplated by the contribution agreement, the
Option Plan administrator will use its discretion to modify the accelerated

                                       68
<PAGE>
vesting provision of the Plan Options to provide that they will vest and become
exercisable with respect to all shares which would have otherwise vested within
12 months following the closing of the contribution agreement. In addition,
pursuant to their terms, all Non-Plan Options will vest and become exercisable
with respect to 75% of the then unvested portion of such Non-Plan Options and
any portion of the Non-Plan Options which remain unexercised as of the closing
of the contribution agreement will terminate. Notwithstanding the foregoing, any
options to acquire Xoom.com shares granted after May 9, 1999 will not vest on an
accelerated basis.

    It is possible that the accelerated vesting of the Plan Options and/or
Non-Plan Options could constitute "excess parachute payments" resulting in the
imposition of an excise tax on the holder of such options and the loss of a tax
deduction by Xoom.com or NBCi. NBCi has agreed to make available to any Xoom.com
employee, a loan to pay the amount of any such excise tax that becomes payable
as a result of such accelerated vesting. The loan will:

    - have a term of 2 years,

    - bear interest at the lowest permissible rate without the imputation of
      income,

    - become repayable upon the termination of such employee's employment with
      NBCi and its affiliates for cause or due to resignation, and

    - be forgiven:

       - with respect to 1/24 of the principal amount of the loan, together with
         accrued interest, on the last day of each 1 month anniversary of the
         closing of the contribution agreement if the employee remains employed
         through such dates, and

       - entirely if such employee is terminated by NBCi without cause or due to
         the employee's death or disability.

    The transactions will result in the accelerated vesting of Plan Options and
Non-Plan Options, of which 527,389 options are held by all of the executive
officers and directors of Xoom.com, except for Mr. Kitze who does not own any
options.

    DIRECTORS AND EXECUTIVE OFFICERS

    Chris Kitze, the chairman of the board of Xoom.com, will be appointed as the
chief executive officer of NBCi and John Harbottle, the chief financial officer
and vice president, finance of Xoom.com, will be appointed as the chief
financial officer and executive vice president, finance, secretary and treasurer
of NBCi. The salaries of Mr. Kitze and Mr. Harbottle will remain the same as
currently paid by Xoom.com. In addition Mr. Kitze and four of the five current
outside directors of Xoom.com will be appointed to the board of directors of
NBCi.

    Mr. Harris, a member of the board of directors of Xoom.com and who will be
appointed as a director of NBCi upon consummation of the transactions, also
serves as a managing director of Bear Stearns which provided advisory services
to Xoom.com in connection with the transactions. Mr. Harris abstained from
voting on the transactions at Xoom.com's board of directors meetings.

    SEVERANCE AGREEMENT

    In September 1999 Xoom.com and Laurent Massa, Xoom.com's president and chief
executive officer, entered into a severance and consulting agreement. Under the
severance agreement, Mr. Massa will resign from Xoom.com upon the closing of the
transactions. After resigning, Mr. Massa will provide consulting services to
NBCi on a part-time basis to assist in the integration of the businesses that
will comprise NBCi, through June 30, 2000.

                                       69
<PAGE>
    Under the severance agreement, Mr. Massa will receive, among other things,
the following benefits from Xoom.com or NBCi, as its successor:

    - the remainder of his 1999 salary ($216,000 per year);

    - the remainder of his 1999 bonus of approximately $39,815;

    - $216,000 severance in January 2000;

    - payment of his COBRA premiums for medical coverage until December 31,
      2000;

    - the unvested portion of Mr. Massa's stock options, 222,576 shares, will
      become fully vested upon the closing of the transactions;

    - Mr. Massa's Non-Plan Options for 175,000 shares will remain exercisable
      for their entire term and will not terminate upon the closing of the
      transactions as they currently provide;

    - Mr. Massa's non-qualified Plan Options for 169,835 shares, will also
      remain exercisable for 24 months after the closing of the transactions;
      and

    - a gross-up payment to reimburse Mr. Massa for all golden parachute excise
      taxes on benefits received pursuant to the severance agreement including
      all income and excise taxes on the gross-up payment.

    In addition, to reflect Mr. Massa's additional responsibilities in
connection with the transactions, in May 1999 Xoom.com granted Mr. Massa
additional options to purchase 25,000 shares of Xoom.com common stock at an
exercise price of $45.50 per share.

    Under the severance agreement, Mr. Massa agreed that for a period of six
months following the termination of the consulting arrangement, or until
December 31, 2000, whichever is longer, he will not, directly or indirectly,

    - divert or attempt to divert from Xoom.com or NBCi any business, including
      the solicitation of customers; or

    - engage in business activities competitive with Xoom.com or NBCi unless Mr.
      Massa proves in court that any of the above actions was done without the
      use of confidential information. Examples of the types of business
      activities in which Mr. Massa has agreed not to engage in include
      community web sites, web site hosting, home page hosting, e-mail, chat
      rooms, electronic newsletters, clip art, software libraries, page
      counters, online greeting cards, software downloading, and working as an
      employee for or consultant to Yahoo, Excite, America Online, Lycos,
      Infoseek, the globe.com, Talk City or Fortune City. Mr. Massa has further
      agreed that in the event he breaches or threatens to breach any of the
      confidentiality or anti-competition provisions, Xoom.com and NBCi shall be
      entitled to liquidated damages from and injunctive relief against Mr.
      Massa. Mr. Massa, Xoom.com and NBCi have executed releases of claims and
      Mr. Massa has covenanted not to sue either Xoom.com or NBCi.

GOVERNMENTAL AND REGULATORY MATTERS

    Under the Hart-Scott-Rodino Act, and the rules promulgated thereunder by the
FTC, the transactions contemplated by the merger agreement and contribution
agreement cannot be consummated until notifications have been given to the FTC
and the Antitrust Division of the Department of Justice and the specified
waiting periods have expired or terminated early. The notifications required
under the Hart-Scott-Rodino Act were furnished to the FTC and the Antitrust
Division by Xoom.com and CNET with respect to the transactions contemplated by
the merger agreement and by Xoom.com and NBC with respect to the transactions
contemplated by the contribution agreement on July 2, 1999. The waiting period
under the Hart-Scott-Rodino Act expired at

                                       70
<PAGE>
11:59 p.m., Eastern Standard time, on August 1, 1999. Notwithstanding the
termination of the waiting periods under the Hart-Scott-Rodino Act, the
Antitrust Division, the FTC or any state or foreign governmental authority could
take such action under the antitrust laws as it deems necessary or desirable in
the public interest. Such action could include seeking to enjoin the
consummation of the transactions contemplated by the merger agreement and
contribution agreement or seeking divestiture of portions of the businesses
intended to be part of NBCi. Private parties may also seek to take legal action
under the antitrust laws under specific circumstances. Pursuant to the merger
agreement, any filing fees required by the Hart-Scott-Rodino Act with respect to
CNET's filing will be paid by Xoom.com.

    There can be no assurance that a challenge to the consummation of the
transactions on antitrust grounds will not be made or that, if such a challenge
were made, the parties to the merger agreement and contribution agreement would
prevail.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES


    The following discussion summarizes the material federal income tax
consequences of the merger of Xenon 3 into Xoom.com pursuant to the merger
agreement that are applicable to Xoom.com stockholders. Morrison & Foerster LLP,
counsel to Xoom.com, is of the opinion that the following discussion accurately
describes such material federal income tax consequences. This disscusion is
based on the Internal Revenue Code, applicable U.S. Treasury Regulations,
judicial authority, and administrative rulings and practice, all as of the date
of this proxy statement/prospectus and all of which are subject to change,
including changes with retroactive effect. The discussion below does not address
any state, local or foreign tax consequences of the Xoom.com merger. Your tax
treatment may vary depending upon your particular situation. You may also be
subject to special rules not discussed below if you are a certain kind of
stockholder of Xoom.com, including:


    - an individual who hold options for Xoom.com common stock;

    - an insurance company;

    - a tax-exempt organization;

    - a financial institution or broker-dealer;

    - a person who is neither a citizen nor resident of the United States;

    - a holder of Xoom.com common stock as part of a hedge, straddle or
      conversion transaction; or

    - a person that does not hold Xoom.com common stock as a capital asset at
      the time of the Xoom.com merger.

    Neither NBCi nor Xoom.com has requested or will request an advance ruling
from the Internal Revenue Service as to the tax consequences of the Xoom.com
merger or any related transaction. The Internal Revenue Service may adopt
positions contrary to that discussed below and such positions could be
sustained.

    You are urged to consult your own tax advisor as to the particular tax
consequences of the merger to you, including the applicability and effect of any
state, local or foreign laws, and the effect of possible changes in applicable
tax laws.


    The obligation of Xoom.com to consummate the merger is conditioned upon the
receipt by Xoom.com of an opinion of its counsel, that on the basis of the
representations set forth or referred to in the opinion, the Xoom.com merger
will be treated for federal income tax purposes as either or both of (A) a
contribution of Xoom.com stock to NBCi qualifying under Section 351 of the
Internal Revenue Code, or (B) a tax-free reorganization under Section 368(a) of
the Internal Revenue Code


                                       71
<PAGE>
and that each of Xoom.com, NBCi and Xenon 3 will be a party to the
reorganization within the meaning of Section 368(b) of the Internal Revenue
Code. Provided that the merger so qualifies:

    - You will not recognize any gain or loss as a result of the receipt of NBCi
      Class A common stock in exchange for your Xoom.com common stock pursuant
      to the Xoom.com merger.

    - Your aggregate tax basis for the shares of NBCi Class A common stock
      received pursuant to the Xoom.com merger will equal your aggregate tax
      basis in shares of Xoom.com common stock held immediately before the
      Xoom.com merger.

    - Your holding period for the shares of NBCi Class A common stock received
      pursuant to the Xoom.com merger will include the period during which the
      shares of Xoom.com common stock are held.


    The tax opinion described above is based upon facts, representations and
assumptions set forth or referred to in the opinion and the continued accuracy
and completeness of representations made by NBCi, Xenon 3 and Xoom.com,
including representations in certificates to be delivered to counsel by the
management of each of NBCi and Xoom.com which if incorrect in any material
respect would jeopardize the conclusions reached by Morrison & Foerster LLP in
the opinion. In addition, in the event that Xoom.com is unable to obtain the tax
opinion, Xoom.com is permitted under the merger agreement to waive the receipt
of such tax opinion as a condition to its obligation to consummate the Xoom.com
merger. As of the date of this proxy statement/prospectus, Xoom.com does not
intend to waive the receipt of the tax opinion as a condition to its obligation
to consummate the Xoom.com merger. In the event of such a failure to obtain the
tax opinion and a determination by Xoom.com to waive such condition to the
consummation of the Xoom.com merger, Xoom.com will resolicit the votes of its
stockholders to approve consummation of the merger.


    The parties to the Xoom.com merger intend that the merger qualify as
tax-free to you pursuant to Section 351 of the Internal Revenue Code and as a
tax-free reorganization pursuant to Section 368 of the Internal Revenue Code.
Therefore, you should report the transaction in your tax returns as tax-free
pursuant to both Sections 351 and Section 368 of the Internal Revenue Code. To
do so, you must include with your federal income tax return for the year of the
Xoom.com merger the statements required by the applicable U.S. Treasury
Regulations. Xoom.com will provide to you a form of statement for filing with
your federal income tax return for the year of the Xoom.com merger.

ACCOUNTING TREATMENT

    NBCi intends to account for the transactions with Xoom.com as the accounting
acquiror in a purchase business combination for financial reporting and
accounting purposes, under generally accepted accounting principles. After the
merger, the results of operations of Xoom.com, the NBC contributed Internet
businesses and SNAP will be included in the consolidated financial statements of
NBCi. The purchase price, that is, the aggregate merger consideration for the
NBC contributed Internet businesses and SNAP, will be allocated based on the
fair values of the assets acquired and the liabilities assumed. Any excess of
cost over the fair value of the net tangible assets acquired of the NBC
contributed Internet businesses and SNAP will be recorded as goodwill and other
intangible assets and will be amortized by charges to operations over their
estimated useful lives in accordance with generally accepted accounting
principles. These allocations will be made based upon valuations and other
studies that have not yet been finalized.

NO APPRAISAL RIGHTS

    Delaware law provides appraisal rights to stockholders of Delaware
corporations in situations involving the merger, consolidation or sale of
substantially all of a company's assets. However, such appraisal rights are not
available to stockholders of a corporation, such as Xoom.com:

    - whose securities are listed on a national securities exchange or are
      designated as a national market security on an interdealer quotation
      system by the National Association of Securities Dealers, Inc.; and

    - whose stockholders are not required to accept in exchange for their stock
      anything other than (A) stock in another corporation listed on a national
      securities exchange or designated as a national market system security on
      an interdealer quotation system by the NASD, and (B) cash in lieu of
      fractional shares.

    Stockholders of Xoom.com will not have appraisal rights with respect to the
Xoom.com merger with Xenon 3 due to the following factors:

    - Xoom.com common stock is traded on The Nasdaq National Market; and

    - Xoom.com stockholders are being offered stock of NBCi, which as a
      condition to the closing of the merger agreement, will be accepted for
      listing on The Nasdaq National Market.

LISTING OF NBCI CLASS A COMMON STOCK

    It is a condition to the transactions that the Class A common stock of NBCi
to be issued pursuant to the merger agreement be approved for listing on The
Nasdaq National Market. NBCi has applied to have the Class A common stock listed
on The Nasdaq National Market. NBCi has also applied to have the Class A common
stock listed on the EASDAQ.

DELISTING AND DEREGISTRATION OF XOOM.COM COMMON STOCK

    If the Xoom.com merger is consummated, Xoom.com common stock will be
delisted from The Nasdaq National Market and EASDAQ and will be deregistered
under the Securities Exchange Act of 1934.

RESTRICTION ON RESALES OF NBCI COMMON STOCK

    The NBCi Class A common stock to be issued under the merger agreement will
have been registered under the Securities Act, thereby allowing such shares to
be freely traded without restriction by all former holders of Xoom.com common
stock who are not "affiliates" of Xoom.com at the time of the special meeting
and who do not become "affiliates" of NBCi after the Xoom.com merger. Persons
who may be deemed to be affiliates of NBCi or Xoom.com generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include officers and directors of NBCi and
Xoom.com, as well as significant stockholders.

    Shares of NBCi Class A common stock received by those stockholders of
Xoom.com who are deemed to be affiliates of Xoom.com may be resold without
registration under the Securities Act only as permitted by Rule 145 under the
Securities Act or as otherwise permitted under the Securities Act. The merger
agreement requires Xoom.com to use commercially reasonable efforts to cause its
affiliates to enter into agreements not to make any public sale of any Xoom.com
Class A common stock received in connection with the Xoom.com merger, except in
compliance with the Securities Act and the rules and regulations thereunder.

    This proxy statement/prospectus does not cover resales of NBCi Class A
common stock received by any person who may be deemed to be an affiliate of
NBCi, SNAP or Xoom.com.

              THE MERGER AGREEMENT AND THE CONTRIBUTION AGREEMENT

THE MERGER AGREEMENT

    CONDITIONS TO THE CLOSING OF THE MERGER AGREEMENT TRANSACTIONS

    Each party's obligation to effect the transactions contemplated by the
merger agreement is subject to the satisfaction or waiver of the following
conditions on or before the closing:

    - no injunction, restraining order or other decree will be in effect that
      restrains or prohibits the consummation of any of the transactions
      contemplated by the merger agreement;

      consummation of the transactions contemplated by the merger agreement
      illegal;

    - all orders, consents and approvals of any governmental authorities legally
      required for the consummation of the transactions contemplated by the
      merger agreement will have been obtained and the waiting periods
      applicable under the Hart-Scott-Rodino Act and other applicable antitrust
      or merger control or competition laws or regulations will have expired or
      have been terminated, except as would not cause a material adverse effect
      to Xoom.com;

    - the adoption of the merger agreement by holders of a majority of all

    XOOM.COM AND SNAP STOCK OPTION PLANS

    Pursuant to the merger agreement, all outstanding Plan Options as well as
all outstanding Non-Plan Options of Xoom.com will, upon the closing of the
merger agreement, be converted into options to purchase an equal number of
shares of NBCi on the same terms and conditions as were applicable to such Plan
Options and Non-Plan Options prior to such conversion.

    Each option to purchase units in SNAP that was outstanding or committed to
be issued as of May 9, 1999 will be converted into an option to purchase a
number of shares of NBCi's Class A common stock equal to the product of 1.2853
times the number of units for which the option is exercisable, which will result
in the issuance of options to purchase an additional 394,894 shares of Class A
common stock. These options will vest and be immediately exercisable to the
extent that they would have otherwise vested within 12 months following the
closing of the merger agreement. Each option to purchase units of SNAP that were
committed and issued after May 9, 1999 will be converted into an option to
purchase a number of shares of NBCi's Class A common stock equal to the number
of units for which the option is exercisable. The per share exercise price of
the NBCi options will equal the per unit exercise price of the SNAP options
divided by the exchange ratio used to convert the SNAP options into options to
purchase Class A common stock of NBCi. The vesting schedule of all of

                                       79
<PAGE>
these options will change from annual to monthly increments and otherwise
correspond with the SNAP schedule, except as noted above in this paragraph.

    PROCEDURES FOR EXCHANGING XOOM.COM STOCK CERTIFICATES

    THE EXCHANGE AGENT.  Promptly after the effective time, NBCi is required to
deposit with a bank or trust company certificates representing the shares of
NBCi Class A common stock to be exchanged for shares of Xoom.com common stock
and any dividends or distributions to which holders of Xoom.com common stock may
be entitled to receive under the merger agreement.

    PROCEDURES FOR EXCHANGING STOCK CERTIFICATES.  Promptly after the effective
time, NBCi will cause the exchange agent to mail to the holders of record of
Xoom.com stock certificates, (1) a letter of transmittal and (2) instructions on
how to surrender Xoom.com stock certificates in exchange for certificates
representing shares of Class A common stock of NBCi and any dividends or other
distributions that they may be entitled to receive under the merger agreement.
HOLDERS OF XOOM.COM COMMON STOCK SHOULD NOT SURRENDER THEIR XOOM.COM STOCK
CERTIFICATES UNTIL THEY RECEIVE THE LETTER OF TRANSMITTAL FROM THE EXCHANGE
AGENT.

    Upon surrendering their Xoom.com stock certificates to the exchange agent
for cancellation, together with the letter of transmittal and any other
documents required by the exchange agent, the holders of Xoom.com stock
certificates will be entitled to receive a certificate representing that number
of shares of NBCi Class A common stock which that holder has the right to
receive and any dividends or other distributions to which the holder is
entitled. Until surrendered to the exchange agent, from and after the effective
time, outstanding Xoom.com stock certificates will be deemed to evidence (1)
only the right to receive the number of full shares of NBCi Class A common stock
into which the shares of Xoom.com common stock formerly represented thereby have
been converted and (2) the right to receive any dividends or distributions
payable under the merger agreement.

    DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  Until each Xoom.com
stockholder surrenders his or her Xoom.com stock certificate in exchange for
NBCi Class A common stock, that stockholder will not receive any dividends or
other distributions declared or made by NBCi after the effective time of the
Xoom.com merger. However, once that stockholder surrenders his or her Xoom.com
stock certificate to the exchange agent, he or she will receive (1) an NBCi
Class A stock certificate, and (2) cash, without interest, as payment for any
dividends or other distributions previously made by NBCi after the effective
time of the Xoom.com merger.

THE STOCK OPTION AGREEMENT

    The stock option agreement grants NBC the unconditional, irrevocable option
to purchase up to 3,415,249 fully paid and nonassessable shares of Xoom.com's
common stock at a price of $73.50 per share; provided that in no event will the
number of shares of common stock for which the option is exercised exceed 19.9%
of the issued and outstanding shares of Xoom.com common stock at the time of
exercise without giving effect to any shares subject or issued pursuant to the
option. The number of shares that may be received upon the exercise of the
option and the option price are subject to adjustments. In the event that any
additional shares of Xoom.com common stock are issued or otherwise become
outstanding after the date of this agreement, the number of shares of common
stock subject to the option shall be increased to equal 19.9% of the Xoom.com
common stock then issued and outstanding without giving effect to any shares
subject or issued pursuant to the option. NBC required Xoom.com to grant this
stock option as a condition to entering into the contribution agreement. The
stock option agreement is attached to this prospectus/proxy statement as
Appendix B-1, and you are urged to read it in its entirety.

    The option is intended to increase the likelihood that the merger will be
completed. Aspects of the stock option agreement may have the effect of
discouraging persons who might now or at any time be interested in acquiring all
or a significant interest in Xoom.com or its assets before the closing of the
contribution agreement.

    NBC and/or any person that becomes a holder of all or part of the option in
accordance with the stock option agreement may exercise the option, in whole or
in part, and from time to time following an "initial triggering event," as
described below, that occurs prior to the termination of the option from an
"exercise termination event," as described below.

    The option will terminate and fail to become exercisable upon the occurrence
of each of the following exercise termination events:

    - the closing of the transactions contemplated by the contribution
      agreement;

    - termination of the contribution agreement if the termination occurs prior
      to an initial triggering event, except a termination by NBC as a result of
      a material default or breach by Xoom.com or NBCi where the default or
      breach is not curable, or if curable, is not cured within 30 days after
      written notice of such breach is given by NBC; and

    - 12 months after termination of the contribution agreement, or a later
      period for specific rights,

     - to the extent necessary to obtain all regulatory approvals for the
       exercise of such rights, and for the expiration of all statutory waiting
       periods;

     - during any period for which an injunction or similar legal prohibition on
       exercise shall be in effect; or

     - to the extent necessary to avoid liability under section 16(b) of the
       Exchange Act by reason of such exercise, if the termination follows or is
       concurrent with an initial triggering event or is a termination by NBC as
       a result of a material default or breach by Xoom.com or NBCi where the
       default or breach is not curable, or if curable, is not cured within 30
       days after written notice of such breach is given by NBC.

    The "initial triggering event" is any of the following events or
transactions, other than the transactions contemplated by the merger agreement,
occurring after the date of the stock option agreement:

    - Xoom.com, without NBC's prior written consent, enters into an agreement to
      engage in an "acquisition transaction," as defined below, with any person
      other than NBC or any of its subsidiaries or affiliates, or the board of
      directors of Xoom.com recommends that its

                                       90
<PAGE>
      stockholders approve or accept any acquisition transaction, other than the
      transactions contemplated by the contribution agreement;

    - Xoom.com, without NBC's prior written consent, authorizes, recommends,
      proposes or publicly announces its intention to authorize, recommend or
      propose, to engage in an acquisition transaction with any person other
      than NBC or its subsidiaries or affiliates, or the board of directors of
      Xoom.com fails to recommend or publicly withdraws or modifies, or publicly
      announces its intention to withdraw or modify, in any manner adverse to
      NBC, its recommendation that the stockholders of Xoom.com adopt the merger
      agreement in anticipation of engaging in an acquisition transaction;


    - stockholders of Xoom.com vote and fail to adopt the merger agreement, or
      vote and fail to instruct Xoom.com to vote to adopt the contribution
      agreement, at a meeting held for that purpose or at any adjournment or
      postponement thereof, or such meeting shall not have been held in
      violation of the contribution agreement or shall have been canceled prior
      to termination of the contribution agreement if, prior to such meeting,
      any person, other than NBC or its subsidiaries or affiliates, makes a bona
      fide proposal to Xoom.com or its stockholders by public announcement or
      written communication that is or becomes the subject of public disclosure
      to engage in an acquisition transaction;


    - any person other than NBC or its subsidiaries or affiliates or any
      subsidiary of Xoom.com acting in a fiduciary capacity in the ordinary
      course of its business acquires beneficial ownership or the right to
      acquire beneficial ownership of, or commences or files a registration
      statement with respect to a tender offer or exchange offer to purchase any
      shares of Xoom.com common stock where consummation results in a beneficial
      ownership of 20% or more of the then outstanding shares of Xoom.com common
      stock;

    - any group other than a group that NBC or its subsidiaries or affiliates
      are a member, is formed that beneficially owns 20% or more of the shares
      of Xoom.com common stock then outstanding; or

    - after a third party has made a bona fide proposal to Xoom.com or its
      stockholders by public announcement or written communication that is or
      becomes the subject of public disclosure to engage in an acquisition
      transaction, Xoom.com:

     - terminates the contribution agreement, prior to receipt of the Xoom.com
       stockholder approval, on five business days written notice, after
       receiving an unsolicited bona fide takeover proposal from a third party
       on terms which (1) the board of directors of Xoom.com determines in good
       faith and after consultation with a financial advisor of nationally
       recognized reputation to be more favorable to the Xoom.com stockholders
       than the transactions contemplated by the contribution agreement and (2)
       the board of directors concludes in good faith based on the advice of
       outside legal counsel that termination of the contribution agreement is
       required to comply with its fiduciary duties under applicable law; or

     - shall have breached any covenant or obligation contained in the merger
       agreement or the contribution agreement and such breach would entitle a
       party other than Xoom.com to terminate such and the breach is not cured
       prior to the date on which the holder of the option gives written notice
       to Xoom.com of its exercise of the option.

    For the purposes of the stock option agreement, an "acquisition transaction"
is any:

    - direct or indirect acquisition or purchase of 20% or more of the assets of
      Xoom.com and its subsidiaries, taken as a whole, or 20% or more of any
      class of equity securities of Xoom.com or any of its subsidiaries; or

                                       91
<PAGE>
    - any tender offer or exchange offer, including by Xoom.com or its
      subsidiaries, that if consummated would result in any person having
      beneficial ownership of 20% or more of any class of equity securities of
      Xoom.com or any of its subsidiaries; or

    - any merger, consolidation, business combination, sale of all or
      substantially all assets, recapitalization, liquidation, dissolution or
      similar transaction involving Xoom.com or any of its subsidiaries;
      provided that any merger, consolidation, sale or similar transaction
      involving only Xoom.com and one or more of its wholly owned subsidiaries
      or involving only any two or more of its wholly owned subsidiaries, will
      not be deemed to be an acquisition transaction if the transaction is not
      entered into in violation of the terms of the contribution agreement.

    A "subsequent triggering event" is either of the following events or
transactions:

    - the acquisition by any person or by a group of beneficial ownership of 50%
      or more of the then outstanding Xoom.com common stock; or

    - where Xoom.com, without NBC's prior written consent, enters into an
      agreement relating to a takeover proposal with any person other than NBC
      or its subsidiaries or affiliates, or the board of directors of Xoom.com
      accepts or approves or recommends that the stockholders of Xoom.com accept
      or approve a takeover proposal.

    The stock option agreement also grants rights to NBC with respect to:

    - the registration of shares of Xoom.com common stock represented by the
      option;

    - NBC's ability to require that Xoom.com repurchase the option or option
      shares, under specified circumstances and if a subsequent trigging event
      has occurred; and

    - NBC's ability to require that Xoom.com issue a substitution option and
      repurchase the substitution option, under specified circumstances.

    In addition, NBC's total profit following exercise of the option will not
exceed $56,707,803.

    In a separate agreement with CNET, NBC has agreed that it will assign to
CNET 20% of its option under the stock option agreement.

THE REGISTRATION RIGHTS AGREEMENT

    NBCi, NBC, GE Investments Subsidiary, CNET, Flying Disc Investments Limited
Partnership and Chris Kitze will enter into the registration rights agreement.

    SHELF REGISTRATION

    NBCi will have the obligation to file a registration statement with the SEC
upon the request of NBC, CNET, Mr. Kitze or any of their respective transferees
for an offering to be made on a continuous basis covering a minimum of $50
million of shares of Class A common stock (valued at the time of such request)
at any time following the later of the 12-month anniversary of the date of the
registration rights agreement and the date upon which NBCi is first able to file
such registration statement on Form S-3.

    DEMAND REGISTRATION RIGHTS

    At any time and from time to time during which there is no effective shelf
registration statement covering all of the Class A common stock registrable
under the registration rights agreement, NBC, CNET, Mr. Kitze or any of their
respective transferees may make a written demand that NBCi effect

                                       92
<PAGE>
the registration under the Securities Act of all or part of their shares of
Class A common stock, provided that:

    - NBC and its transferees, on behalf of NBC and GE Investments Subsidiary,
      shall have only four such demand rights, one of which can be made on Form
      S-1 and one of which can be for a shelf registration;

    - CNET and its transferees shall have only three such demand rights, two of
      which can be made on Form S-1 and one of which can be for a shelf
      registration;

    - Mr. Kitze, on behalf of himself and Flying Disc, shall have only three
      such demand rights, one of which can be made on Form S-1 and one of which
      can be for a shelf registration;

    - the market value of the shares to be included in the demand registration
      on Form S-1 must be at least $25,000,000, valued at the time of such
      request;

    - no demand can be made prior to six months after the effective date of the
      immediately preceding demand registration; and

    - in any underwritten offering, shares may be excluded by the underwriters
      based on market conditions and marketing factors.

    Priority of inclusion in demand registrations is given first to the party or
parties initiating the demand registration; then inclusion is pro rata among the
other parties based on the amount of shares requested to be included, provided
that the Class A common stock requested by NBCi to be included in such offering
will comprise the lesser of 50% of the securities to be sold or all of the
securities requested to be included by NBCi.

    CNET will be entitled to exercise its initial demand right before other
parties for a period of 60 days following consummation of the contribution
agreement. In such event, the Class A common stock requested by CNET to be
included in such offering may be reduced to the lesser of 50% of the securities
to be sold or all of the securities requested to be included by CNET, with the
remainder to be allocated between NBCi and Mr. Kitze.

    PIGGYBACK REGISTRATION

    If, at any time, NBCi proposes to register any of its equity securities,
whether for its own account or for the account of a third party, each party may
request that NBCi include any or all of their shares in the registration.
Priority of inclusion in piggyback registrations is given first to the party
initiating the registration and NBCi, then pro rata among the other parties
based on the amount of shares requested to be included. Securities of a
different class than those included by NBCi may be excluded at the reasonable
discretion of the underwriters.

    In the event a registration statement is filed by NBCi during the six month
period after the effective date of the registration statement filed as a result
of CNET's exercise of its initial demand right, the Class A common stock
requested by CNET to be included in such offering will comprise the lesser of
25% of the securities to be sold or all of the securities requested to be
included by CNET, but will not exceed 1,000,000 shares of Class A common stock.
However, if the number of CNET's shares of Class A common stock included in such
registration exceeds 500,000, such inclusion shall be deemed an exercise by CNET
of one of its demand rights.

    OTHER PROVISIONS

    The Registration Rights Agreement contains customary terms and conditions
for transactions of this type including provisions that NBCi:

    - will covenant to become S-3 eligible;

                                       93
<PAGE>
    - will file any requested registration statement as soon as practicable but
      in no event later than 45 days after the notice of demand or 90 days in
      the case of the first demand registration; and

    - will use its best efforts to cause the effectiveness of any registration
      statement filed on behalf of the parties.

      satisfactory to NBC to be bound by all of the provision of the voting
      agreement;

                                       94

THE BRAND INTEGRATION AND LICENSE AGREEMENT

    In connection with the transactions, NBC and NBC Multimedia entered into a
license agreement, which will be assigned to NBCi upon consummation of the
transactions. Among other rights, the agreement grants NBC Multimedia a
non-exclusive license to use the trademark "NBC", the NBC multicolor logo and
the NBC soundmark in connection with NBC.com, VideoSeeker.com and NBC-IN.com and
the portal, community and e-commerce services of NBCi. In addition, the license
agreement also provides NBC Multimedia with specified license rights to the
Website addresses for NBC.com, NBC-IN.com and VideoSeeker.com, although NBC
retains title to such Website addresses.

    The license agreement also grants the licensee an exclusive license to use,
reproduce and display on the NBCi Internet sites short excerpts from some NBC
television programs and to create interactive programs therefrom, in accordance
with the terms of the license.

    The license agreement further provides for quality controls to ensure that
standards are met in the use of the licensed marks. Among other things, NBC
retains control over the creative and editorial aspects of NBC.com and the
licensee covenants to maintain and assist in maintaining the quality of the
contributed sites and related services and to submit for approval to NBC
proposed uses of the licensed marks.

    The license agreement contains limited non-competition provisions
restricting both parties from competing with each other in some areas of
business. For example:

    - both parties are limited in their ability to authorize co-branding of any
      of the their respective marks by a competitor of the other;

    - neither party can invest in, purchase or loan money to a competitor of the
      other; and

    - NBC grants first look rights in relation to acquisitions of non-primary
      competitors of NBCi and related businesses.

    The provisions of the license agreement are subject to general exceptions
concerning, among other things, investments, market research and transactions in
the ordinary course of business. In particular, NBC is expressly permitted to
own, control and operate the businesses connected with CNBC.com and MSNBC.com.

    The license agreement will continue in perpetuity unless terminated on
grounds set forth in the license agreement, including:

    - by either party, if NBC or its subsidiaries no longer own at least 5% of
      NBCi;

    - by either party, in the event of, among other things, the insolvency,
      bankruptcy or receivership of the other party;

    - by NBC, in the event of a change of control of NBCi;

    - material breach of the license agreement; or

    - repeated breaches of substantive quality controls in the license
      agreement.

                                       95

THE CONVERTIBLE NOTES


    In connection with the transactions, NBCi will issue two subordinated zero
coupon convertible notes due 2006. The convertible note to be issued to NBC
Multimedia will have a principal at maturity of $39,477,953 and will be
convertible by NBC Multimedia into 471,031 shares of Class B common stock of
NBCi at any time after the first anniversary of closing. The other convertible
note to be purchased by GE Investments Subsidiary will have a principal at
maturity of $447,416,805 and will be convertible into 5,338,357 shares of Class
B common stock of NBCi at any time after the first anniversary of closing. The
imputed original issue discount interest rate on both of the convertible notes
is 4%.


    If both convertible notes are converted in full at a time when NBC and its
affiliates own 35% or more of the outstanding shares of NBCi common stock, the
holders of the Class B common stock would have the right to elect seven of the
13 members of the NBCi board of directors and the holders of the Class A common
stock would have the right to elect the remaining six directors. If both of the
convertible notes are not converted in full, the holders of the Class B common
stock will have the right to elect six of the 13 members of the NBCi board of
directors. The holders of the Class A common stock will have the right to elect
the remaining seven directors.

    Each of the notes matures on the seventh anniversary of the closing of the
transactions and contains customary anti-dilution provisions. In the event of a
change of control, merger or similar transactions, each note is redeemable at
the purchaser's option at a price equal to the aggregate principal amount or
equivalent value in shares. NBCi may redeem each of the notes with cash, stock
or both after the fifth anniversary of the closing on at least 30 days notice
and at a redemption price equal to the principal at maturity of such note less
any original issue discount not accrued on the redemption date.

    Each of the notes provides that payments of principal and interest shall be
subordinated in right of payment to the prior payment in full of all of NBCi's
other indebtedness. Such subordination, however, does not limit the payment of
principal of and interest on the notes in accordance with their terms unless, at
the time of such payment, there is a default in the payment of principal of or
interest on NBCi's other indebtedness.

ADVERTISING AGREEMENT

    At closing, NBC and NBCi will enter into an advertising agreement pursuant
to which NBCi will purchase 15-, 30- and 60-second advertising spots valued at
$405 million over a four-year period, on the NBC Television Network, CNBC, MSNBC
and NBC's owned and operated television stations. The advertisements will be
subject to standard terms and conditions generally applicable to such
advertising. The advertising purchased under the advertising agreement will be
valued at 85% of the gross market rate charged by NBC at the time of the order,
whether on or off any rate cards. The rate charged will be adjusted for any
applicable frequency discounts, early payment discounts, rebates and other
discounts charged by NBC to an advertisier purchasing the same amount as NBCi
purchases in any given broadcast year. The advertising agreement may be
terminated by NBC in the event of a change of control of NBCi, a bankruptcy
event with respect to NBCi or a material breach by NBCi that is not cured within
30 days. The advertising agreement may be terminated by NBCi upon a material
breach by NBC that is not cured within 30 days.

    At the end of the four-year advertising period, NBC and NBCi have agreed to
negotiate concerning the purchase of an additional $500 million of advertising
on NBC during the following six years, at a price and subject to terms and
conditions to be mutually agreed upon by NBC and NBCi.

GOVERNANCE AGREEMENT

agreement with NBCi under which it will agree not to:

    - acquire additional shares of NBCi;

    - solicit proxies in connection an amendment to NBCi's restated certificate
      of incorporation or for the election of Class A directors; or

    These limitations will terminate if a third party initiates a tender offer
for NBCi common stock or NBCi agrees to enter into a transaction that would
result in a change in control. The governance agreement will also contain
provisions with respect to NBC's rights to purchase additional shares of Class B
common stock in the event NBCi issues shares of capital stock and the right to
designate nominees to the board of directors of NBCi. See page 222.


CNET VOTING AND RIGHT OF FIRST OFFER AGREEMENT

      and sale of substantially all assets or equity securities of NBCi; and

    - other material transactions, including any sale of more than 5% of the
      total assets or equity securities of NBCi.

    In addition, NBC has a right of first offer to purchase shares of Class A
common stock owned by CNET upon CNET's notice to NBC describing the material
terms of the proposed sale or transfer to a third party other than NBC.

CNET STANDSTILL AGREEMENT

    CNET will enter into a standstill agreement with NBCi under which it will

except transfers in connection with a third party tender offer or a merger,
consolidation or reorganization of NBCi.

CNET CARRIAGE AGREEMENT

    In connection with the transactions, CNET, SNAP and NBC amended the carriage
agreement between CNET, SNAP and NBC. As amended, the carriage agreement
provides that specified headlines, summaries and other information services from
CNET Internet sites receive preferred placement on SNAP Internet sites, through,
among other things, preferred links and restrictions on the sale by SNAP of
positions on its Internet sites to third party content providers. The amended
carriage agreement also provides that for an exclusivity period of one year from
May 9, 1999, with the exception of editorial content, SNAP will be the preferred
general Internet directory service on any CNET site. The amended carriage
agreement contains limited non-compete provisions restricting CNET from entering
into relationships with competitors of SNAP, including co-branding agreements,
investments and acquisitions, and restricts CNET from operating its Search.com
Web site in competition with SNAP until May 9, 2000.

CNBC CARRIAGE AGREEMENT

    CNBC and NBCi intend to enter into a carriage agreement after the closing of
the transactions pursuant to which CNBC will provide selected services and some
content from CNBC.com to NBCi.

EQUITY INVESTMENT AND RESTRUCTURINGS

    On June 11, 1999, Xoom.com, NBC and other parties entered into the stock
purchase agreement, the amended and restated agreement and plan of contribution,
investment and merger, which amended and restated the agreement and plan of
contribution, investment and merger entered into on May 9, 1999 and a
registration rights agreement with respect to the common stock purchased
pursuant to the stock purchase agreement. The registration rights terminate upon
consummation of the contribution agreement. Pursuant to the stock purchase
agreement, on July 30, 1999 NBC acquired 960,028 shares of common stock of
Xoom.com, for $57.29 per share in cash. NBC has agreed to vote all of these
shares in favor of the adoption of the merger agreement and in favor of the
approval of Xoom.com's adoption of the contribution agreement. The amended and
restated agreement and plan of contribution, investment and merger resulted in

                         NBCI 1999 STOCK INCENTIVE PLAN

    This section of the proxy statement/prospectus describes the material
aspects of the stock incentive plan. The following description of the stock
incentive plan is qualified in its entirety by reference to the stock incentive
plan, which is attached as Appendix E to this proxy statement/prospectus. You
are urged to read the stock incentive plan.

    The stockholders of Xoom.com are being asked to approve the stock incentive
plan. In October 1999, NBCi's board of directors adopted the stock incentive
plan, subject to the approval of the stockholders of Xoom.com and the board of
directors of Xoom.com, as NBCi's sole stockholder, approved the stock incentive
plan. If stockholder approval is obtained, the stock incentive plan will be
effective as of immediately prior to the closing of the merger agreement.

PURPOSES

    The purposes of the stock incentive plan are to promote the interests of
NBCi and its stockholders by:

    - attracting and retaining exceptional officers, directors and other key
      employees and consultants of NBCi and its subsidiaries;

    - motivating those individuals with performance-related incentives to
      achieve longer-range performance goals; and

    - enabling those individuals to participate in the long-term growth and
      financial success of NBCi.

ADMINISTRATION/ELIGIBLE PARTICIPANTS

    The stock incentive plan is administered by an administrator, defined as the
board of directors of NBCi or one or more committees designated by the board of
directors. The administrator of the stock incentive plan is expected to be one
or more committees of two or more members of the board of directors of NBCi. The
committee that administers the plan for grants to officers and directors will
consist of committee members intended to be "non-employee directors," within the
meaning of Rule 16b-3 promulgated under the Securities Exchange Act, to the
extent Rule 16b-3 is applicable to NBCi and the stock incentive plan. The
committee that administers the plan for grants to officers who are or may
reasonably be expected to become "covered employees" within the meaning of
Internal Revenue Code Section 162(m) will consist of "outside directors," within
the meaning of Section 162(m). The mere fact that a committee member fails to
qualify as a non-employee director or outside director, however, will not
invalidate any award made by the committee which award is otherwise validly made
under the stock incentive plan.

    Any officer or other employee, director or consultant to NBCi or any of its
subsidiaries will be eligible to be designated a participant under the stock
incentive plan.

    As of August 31, 1999, NBCi and the companies that will, upon completion of
the transactions, be subsidiaries of NBCi had approximately 19 officers, 479
employees and 18 directors/managers, each of whom would be eligible to be
granted awards by the committee under the stock incentive plan upon completion
of the transactions. The committee has the authority to determine the
participants to whom awards shall be granted under the stock incentive plan.
However, the board of directors of NBCi may delegate to one or more officers of
NBCi the authority to grant awards to participants who are not officers or
directors of NBCi subject to Section 16 of the Securities Exchange Act or
"covered employees" within the meaning of Section 162(m).

                                       99

NUMBER OF SHARES AUTHORIZED UNDER THE STOCK INCENTIVE PLAN

    Initially, the stock incentive plan authorizes the grant of awards for up to
13,500,000 shares of NBCi's Class A common stock. On the first business day of
each calendar year beginning 2001, the maximum number of shares issuable under
the stock incentive plan will be increased to that number that, when added to
the number of unissued shares under outstanding awards, equals 30% of the number
of outstanding shares of NBCi common stock on a fully diluted basis as of
December 31 of the immediately preceding calendar year. The maximum number of
shares available for grant of incentive stock options will be 13,500,000, which
amount is not subject to annual adjustment. The number of shares reserved for
issuance under the stock incentive plan is subject to adjustment to avoid
dilution or enlargement of intended benefits in the event of certain significant
corporate events.

    Awards may be made in the form of:

    - nonqualified stock options;

    - stock options intended to qualify as incentive stock options under Section
      422 of the Internal Revenue Code;

    - stock appreciation rights;

    - restricted stock;

    - performance awards and/or performance units;

    - dividend equivalent rights; or

    - other stock based awards.

    The maximum number of shares of Class A common stock with respect to which
stock options and stock appreciation rights may be granted to any participant in
the stock incentive plan in any calendar year may not exceed 1,000,000 shares.
If, after the effective date of the stock incentive plan, any shares of Class A
common stock covered by an award granted under the stock incentive plan, or to
which such an award relates, are forfeited, or if an award has expired,
terminated or been cancelled for any reason, other than by reason of exercise or
vesting, or if any unissued shares are retained by NBCi upon exercise of an
award to satisfy the exercise price or any withholding taxes, then the shares of
Class A common stock covered by such award shall again be, or shall become,
shares of Class A common stock with respect to which awards may be granted under
the stock incentive plan.

SUBSTITUTE AWARDS

    Awards may be made under the stock incentive plan in assumption of, or in
substitution for, outstanding awards previously granted by NBCi or its
affiliates or a company acquired by NBCi or its affiliates with which NBCi or
its affiliates combines. The number of shares underlying any such assumed or
substitute awards will be counted towards the aggregate number of shares of
Class A common stock which are available for grant under awards made under the
stock incentive plan.

TERMS AND CONDITIONS OF AWARDS UNDER THE STOCK INCENTIVE PLAN

    Awards made under the stock incentive plan will be subject to the terms and
conditions, vesting requirements, form and timing of exercise or settlement, as
applicable, as may be determined by the committee and specified in the
applicable award agreement or thereafter; provided that (1) stock options
intended to qualify as incentive stock options will be subject to terms and
conditions that comply with the rules applicable to incentive stock options and
(2) the exercise price per share of any stock option granted under the stock
incentive plan may not be less than 85% of the fair market value per share on
the date of grant.

                                      100
<PAGE>
    Payment in respect of the exercise of an option granted under the stock
incentive plan may be made:

    - in cash or its equivalent;

    - through the delivery of a promissory note with such recourse, interest,
      security and redemption provisions as the committee deems appropriate;

    - by exchanging shares of Class A common stock;

    - subject to such rules as may be established by the committee, through
      delivery of irrevocable instructions to a broker to sell the shares being
      acquired upon exercise of the option and to deliver to NBCi an amount
      equal to the aggregate exercise price; or

    - by any combination of the foregoing, provided that the combined value of
      the consideration received is at least equal to the aggregate exercise
      price of the option.

    The committee may designate stock options and stock appreciation rights
intended to qualify as "performance-based compensation" under Section 162(m),
provided that the exercise price is established by the committee to be at least
equal to the fair market value per share as of the date of grant. This form of
award enables the committee to treat certain other awards under the stock
incentive plan as "performance-based compensation" and thus preserve
deductibility by NBCi for federal income tax purposes of such awards which are
made to individuals who are "covered employees" as defined in Section 162(m).

    Under Code Section 162(m) no deduction is allowed in any taxable year of
NBCi for compensation in excess of $1 million paid to its chief executive
officer and each of its four most highly paid other executive officers who are
serving in such capacities as of the last day of such taxable year. An exception
to this rule applies to compensation that is paid pursuant to a stock incentive
plan approved by stockholders and that specifies, among other things, the
maximum number of shares with respect to which options and stock appreciation
rights may be granted to eligible employees under such plan during a specified
period. Compensation paid pursuant to options and stock appreciation rights
granted under such a plan and with an exercise price equal to the fair market
value of NBCi's stock on the date of grant is deemed to be inherently
performance-based, since such awards provide value to employees only if the
stock price appreciates.

TRANSFERABILITY

    Incentive stock options may only be exercised by the optionee during the
optionee's lifetime and may not be transferred or encumbered by the optionee
except by will or by the laws of descent and distribution. Any such purported
transfer or encumbrance shall be void and unenforceable against NBCi or any
affiliate. The designation of a beneficiary is not considered a transfer or
encumbrance. The committee has the discretion under the stock incentive plan to
provide that other awards granted under the stock incentive plan may be
transferred without consideration to certain family members or trusts,
partnerships or limited liability companies in which the original grantee and/or
his or her family members own a 50% beneficial interest or a 50% voting
interest.

CHANGE OF CONTROL

    In the event of a change in control, as defined below, each currently
outstanding award under the stock incentive plan automatically will have its
vesting accelerated by 12 months on the effective date of the corporate
transaction. Upon consummation of the corporate transaction, all outstanding
awards will terminate unless such award is assumed or replaced with a comparable
award or cash incentive program by the successor corporation or its affiliates
or such award is purchased for cash. If within 12 months of a change in control,
a participant is subsequently terminated or leaves for good reason, each
outstanding award of the participant shall become fully vested and exercisable.
Under the stock

                                      101
<PAGE>
incentive plan a "change in control" is defined as any merger, consolidation or
other form of business combination in which the stockholders of NBCi do not own
at least 50% of the combined voting power in the surviving entity, the
acquisition of 50% of the total combined voting power of NBCi's outstanding
securities or a change in a majority of the board of directors over a period of
three years by reason of one or more contested elections, except that any
increase in securities ownership by NBC or its successors does not constitute a
change in control.

    The stock incentive plan also provides for the accelerated vesting of
outstanding awards held by participants primarily in the service of an
affiliated entity of NBCi, upon the sale, merger, consolidation or sale of
substantially all of the assets of such entity.

AMENDMENT TO STOCK INCENTIVE PLAN

    The board of directors of NBCi may amend, suspend or terminate the stock
incentive plan; provided that no amendment or termination will be made without
stockholder approval if such approval is necessary to comply with any tax or
regulatory requirement applicable to the stock incentive plan. In addition, no
action that would adversely affect the rights of any participant to awards
previously granted under the stock incentive plan will be effective without the
participant's consent.

FEDERAL INCOME TAX CONSEQUENCES RELATING TO STOCK OPTIONS

    The following summary of the federal income tax consequences of the grant
and exercise of nonqualified and incentive stock options awarded under the stock
incentive plan, and the disposition of shares of Class A common stock purchased
pursuant to the exercise of such stock options, is intended to reflect the
current provisions of the Internal Revenue Code and the regulations thereunder.
This summary is not intended to be a complete statement of applicable law, nor
does it address state and local tax considerations.

    No income will be realized by an optionee when a nonqualified stock option
is granted. Upon exercise of a nonqualified stock option, the optionee will
recognize ordinary compensation income in an amount equal to the excess, if any,
of the fair market value of the underlying stock over the option exercise price
at the time of exercise, referred to as the "spread". The spread will be
deductible by NBCi for federal income tax purposes subject to the possible
limitations on deductibility, including those under Sections 280G and 162(m) of
the Internal Revenue Code, of compensation paid to specified executives. The
optionee's tax basis in the underlying shares acquired by exercise of a
nonqualified stock option will equal the exercise price plus the amount taxable
as compensation to the optionee. Upon sale of the shares received by the
optionee upon exercise of the nonqualified stock option, any gain or loss is
generally long-term or short-term capital gain or loss, depending on the holding
period. The optionee's holding period for shares acquired pursuant to the
exercise of a nonqualified stock option will begin on the date of exercise of
such option.

    Pursuant to rules under Section 16(b) of the Securities Exchange Act, the
grant of an option, and not its exercise, to a person who is subject to the
reporting and short-swing profit provisions under Section 16 of the Securities
Exchange Act begins the six-month period of potential short-swing liability. The
taxable event for the exercise of an option that has been outstanding at least
six months ordinarily will be the date of exercise. If an option is exercised by
a person subject to Section 16 within six months after the date of grant,
however, taxation ordinarily will be deferred until the date which is six months
after the date of grant, unless the person has filed a timely election pursuant
to Section 83(b) of the Internal Revenue Code to be taxed on the date of
exercise. The six month period of potential short-swing liability may be
eliminated if the option grant (1) is approved in advance by NBCi's board of
directors, or a committee composed solely of two or more non-employee directors,
or (2) approved in advance, or subsequently ratified by NBCi's shareholders no
later than the next annual meeting of shareholders. Consequently, the taxable
event for the exercise of an option that satisfies either of the conditions
described in clauses (1) or (2) above will be the date of exercise.

                                      102
<PAGE>
    The payment by an optionee of the exercise price, in full or in part, with
previously acquired shares of NBCi common stock will not affect the tax
treatment of the exercise described above. No gain or loss generally will be
recognized by the optionee upon the surrender of the previously acquired shares
to NBCi, and shares received by the optionee, equal in number to the previously
surrendered shares of NBCi common stock, will have the same tax basis as the
shares surrendered to NBCi and will have a holding period that includes the
holding period of the shares surrendered. The value of the shares of NBCi common
stock received by the optionee in excess of the number of shares surrendered to
NBCi will be taxable to the optionee. Such additional shares of NBCi common
stock will have a tax basis equal to the fair market value of such additional
shares as of the date ordinary income is recognized, and will have a holding
period that begins on the date ordinary income is recognized.

    The Internal Revenue Code requires that, for incentive stock option
treatment, shares of Class A common stock acquired through exercise of an
incentive stock option cannot be disposed of before two years from the date of
grant and one year from the date of exercise. Incentive stock option holders
will generally incur no federal income tax liability at the time of grant or
upon exercise of such options. However, the spread will be an "item of
adjustment" which may give rise to "alternative minimum tax" liability at the
time of exercise. If the optionee does not dispose of the shares of NBCi common
stock before two years from the date of grant and one year from the date of
exercise, the difference between the exercise price and the amount realized upon
disposition of the shares of NBCi common stock will constitute long-term capital
gain or loss, as the case may be. Assuming both the holding periods are
satisfied, no deduction will be allowable to NBCi for federal income tax
purposes in connection with the grant or exercise of the option. If, within two
years of the date of grant or within one year from the date of exercise, the
holder of shares of NBCi common stock acquired through the exercise of an
incentive stock option disposes of the shares, the optionee will generally
realize ordinary taxable compensation at the time of the disposition equal to
the difference between the exercise price and the lesser of the fair market
value of the stock on the date of initial exercise or the amount realized on the
subsequent disposition, and this amount will generally be deductible by NBCi for
federal income tax purposes, subject to limitations on deductibility including
those in Sections 280G and 162(m) of the Internal Revenue Code for compensation
paid to executives designated in those sections.

ANTICIPATED AWARDS

    As of the date of this proxy statement/prospectus, no executive officer or
director, and no associate of any executive officer or director, has been
granted any options under the stock incentive plan. Assuming that the stock
incentive plan is approved, upon the closing of the merger agreement outstanding
options held by the directors, officers and employees of Xoom.com and SNAP will
be converted into options to purchase shares of Class A common stock of NBCi in
the amounts set forth below based on the number of stock options held by such
individuals on the record date:

                                   (STEP ONE)

    The following unaudited pro forma condensed combined financial information
for NBCi gives effect to the step one transaction among Xoom.com, NBC, CNET and
SNAP. The step one transaction includes NBCi's acquisition of CNET's ownership
interest in SNAP. In addition, the unaudited pro forma condensed combined
financial information for NBCi reflects NBC's purchase of 960,028 shares of
Xoom.com's common stock for $55 million on July 30, 1999, which was separate and
apart from step one. The pro forma historical financial information has been
derived from the historical financial statements of Xoom.com and the Xoom.com
pro forma financial statements, and should be read in conjunction with those
financial statements and the related notes which begin on page F-3 and F-127,
respectively, of this proxy statement/prospectus.

    The step one unaudited pro forma condensed combined balance sheet assumes
that step one of the transaction took place as of June 30, 1999.

    The step one unaudited pro forma condensed combined statements of operations
gives effect to Xoom.com's pro forma historical statements of operations and the
equity loss attributable to SNAP for the year ended December 31, 1998 and for
the six months ended June 30, 1999 as if step one had occurred at the beginning
of each period presented.

    The step one unaudited pro forma condensed combined information is presented
for illustrative purposes only and is not necessarily indicative of the
operating results or financial position that would have occurred if the
transaction had been consummated at the dates indicated, nor is it necessarily
indicative of future operating results or financial position of the combined
companies and should not be construed as representative of these amounts for any
future dates or periods.

the respective historical and/or pro forma financial statements of Xoom.com,
SNAP, and the NBC Multimedia Division, and should be read in conjunction with
those financial statements and the related notes which begin on pages F-3, F-34
and F-51 in this proxy statement/prospectus, respectively.

    The unaudited pro forma condensed combined balance sheet as of June 30, 1999
has been prepared assuming the transactions took place as of that date and
includes the allocation of the total purchase consideration to the fair values
of the assets and liabilities of SNAP and the NBC Multimedia Division, based on
a preliminary valuation.

    The unaudited pro forma condensed combined statements of operations combine
the Xoom.com pro forma historical statements of operations and the historical
statements of operations of SNAP and the NBC Multimedia Division for the year
ended December 31, 1998 and the six months ended June 30, 1999; reflect NBC's
investment in Xoom.com's common stock; and give effect to the transactions,
including the amortization of goodwill and other intangible assets, as if they
had occurred at the beginning of each period presented.

    The final purchase price allocation will be calculated based on NBC
Multimedia's and SNAP's balance sheets and SNAP's stock options outstanding at
the date the transactions are consummated.

    The unaudited pro forma condensed combined information is presented for
illustrative purposes only and is not necessarily indicative of the operating
results or financial position that would have occurred if the transaction had
been consummated at the dates indicated, nor is it necessarily indicative of
future operating results or financial position of the combined companies and
should not be construed as representative of these amounts for any future dates
or periods.

    As set forth in the pro forma condensed combined statements of operations,
NBCi experienced net losses for the six months ended June 30, 1999 and the year
ended December 31, 1998. We believe that we have the financial resources needed
to meet the presently anticipated business requirements of NBCi, including
capital expenditure and strategic operating programs, for at least the next 12
months. Thereafter, if cash generated by operations is insufficient to satisfy
our liquidity requirements, we may need to sell additional equity or debt
securities or obtain additional credit facilities. The sale of additional equity
or convertible debt securities may result in additional dilution to our
stockholders. We may not be able to raise any such capital on terms acceptable
to us or at all.

              NOTES TO THE SELECTED UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL INFORMATION

                              (STEPS ONE AND TWO)

    The total estimated purchase cost assumes that both the step one and step
two transactions are completed and has been allocated on a preliminary basis to
assets and liabilities based on management's estimate of their fair values, with
Xoom.com treated as the accounting acquiror. The excess of the purchase cost
over the fair value of the net assets acquired has been allocated to goodwill.
The final purchase price allocation will be calculated based on NBC Multimedia's
and SNAP's balance sheets and SNAP's stock options outstanding at the date the
transactions are consummated.

    The adjustments to the unaudited pro forma condensed combined balance sheet
as of June 30, 1999, have been calculated as if the transactions occurred on
June 30, 1999 and are as follows:

(A)(1) To reflect the acquisition by NBCi of NBC.com, NBC-IN.com and
       VideoSeeker, NBC Multimedia's ownership interest in SNAP, and a 10%
       ownership interest in CNBC.com for an estimated purchase price of
       $1,473,336,000. The purchase consideration consists of the following:

    - Issuance of 23,590,680 shares of NBCi Class B common stock with a fair
      value of $1,103,336,000. The fair value per share of Xoom.com's common
      stock is being used to determine the purchase price, as Xoom.com is
      treated as the accounting acquiror. Therefore, the fair value per share of
      NBCi's common stock issued is based on the average closing price of
      Xoom.com's common stock on June 14, 1999 (the date of the announcement of
      the stock purchase agreement between Xoom.com and NBC) and the three days
      prior and subsequent to such date.

    - Issuance of (i) a zero coupon convertible note of NBCi with a principal at
      maturity of $39,447,953; and (ii) a zero coupon convertible note of NBCi
      with a principal at maturity of $447,416,805. The convertible notes
      payable have been recorded at their present value of approximately
      $370,000,000, with an effective interest rate of 4% per annum.

   (2) To reflect the issuance of 7,245,063 shares of NBCi's Class A common
       stock with a fair value per share of $46.77 for an aggregate amount of
       $338,852,000 or approximately 81% (39% on a fully diluted basis) of SNAP.
       The fair value per share of NBCi's common stock issued is based on the
       average closing price of Xoom.com's common stock on June 14, 1999 (the
       announcement date of the stock purchase agreement between Xoom.com and
       NBC) and the three days prior and subsequent to such date. See Merger
       Agreement on page 7 for a description of this transaction.

(B)(1) To reflect the additional estimated purchase price of $107,270,000
       related to (i) the assumption of SNAP's options and (ii) estimated merger
       costs. This additional estimated purchase price of $107,270,000 consists
       of the following:

    - Assumption of options to purchase 2,029,193 shares of NBCi's Class A
      common stock with a fair value of $83,770,000. 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 14, 1999 and the three
         days prior and subsequent to such date.

       - Expected life of 4 years

       - Expected volatility of 1.0

       - Risk free interest rate of 5.9%

       - Expected dividend rate of 0%

    - Estimated related merger costs consisting of the following:

       - Investment banking fees               $17,250,000

       - Attorney, accountant and printing fees  4,250,000

       - Filing and registration costs            400,000

       - Merger-related restructuring costs      1,600,000
                                               -----------

                                               $23,500,000
                                               -----------
                                               -----------

    (2) To allocate the total purchase price of the transaction ($1,919,458,000)

        content, and other brand name                      50,600,000

       - Goodwill                                       1,408,108,000
                                                       --------------

                                                       $1,588,938,000
                                                       --------------
                                                       --------------

    (C) To reflect the elimination of (i) the historical members' equity
       accounts of SNAP and (ii) the historical parent company investment and
       net advances of the NBC Multimedia Division.

    (D) To record the assignment to NBCi of a note of NBC in the amount of $340
       million ($78,288,000 current portion and $261,712,000 long-term portion),
       with a term of 4 years and an interest rate of 5.4% per annum.

    (E) To eliminate the gross margin associated with the SNAP deferred revenue
       and to eliminate the deferred revenue of the NBC Multimedia Division.

    (F) To record the repayment by NBCi of SNAP's revolving line of credit.

       1999 and executed on July 30, 1999. See Xoom.com/NBC Stock Purchase
       Agreement on page 11 for a description of this transaction.

    The adjustments to the unaudited pro forma condensed combined statements of
operations for the year ended December 31, 1998 and the six months ended June
30, 1999, assume that step two occurred as of January 1, 1998 and January 1,
1999, respectively and are as follows:

    (H) To reflect the amortization of goodwill and other intangible assets
       resulting from the transactions. The goodwill and other intangible assets

       to an affiliate of NBC, as if the shares had been outstanding for the

       has not been included, as its inclusion would be anti-dilutive.

                                NBCI'S BUSINESS

OVERVIEW

    NBCi seeks to combine the NBC media brand with the complementary portal and
navigation services of SNAP and community and direct e-commerce services of
Xoom.com to deliver a comprehensive and compelling Internet experience to a
broad audience. NBCi intends to offer these core services through its primary
consumer brand SNAP. NBCi believes its core services will provide the foundation
for a next generation media company capable of reaching users through a variety
of media including television and the Internet. NBCi believes that its services
will create an environment that attracts users and encourages repeat visits,
long term usage and customer loyalty. As a result, NBCi expects to have a large
consumer audience as well as an extensive consumer data base that will be
attractive to advertisers and e-commerce partners seeking to deliver targeted
messages and offers. By providing these services, NBCi intends to become a
critical meeting point for consumers, vendors and advertisers.

    Upon the closing of the transactions, NBCi's Internet properties and
services will include:


    - SNAP, the owner of Snap.com, one of the fastest growing major Internet
      portals from July 1998 to July 1999 according to Media Metrix based on the
      percentage increase in reach among home and work users, providing a
      comprehensive set of information, navigation and content aggregation
      services;


    - Xoom.com, the owner of one of the fastest growing community sites from
      July 1998 to July 1999, according to Media Metrix based on the percentage
      increase in reach among home and work users, providing direct e-commerce
      and community services which will be integrated within the Snap.com Web
      site;

    - NBC.com, NBC-IN.com and VideoSeeker, providing access to a broad base of
      differentiated users, unique content and opportunities for cross-selling
      through the full integration of these properties throughout the Snap.com
      Web site; and

    - a 10% ownership interest in CNBC.com LLC, which operates CNBC.com, a newly
      launched Web site providing comprehensive financial information and
      analytic tools on the Web.

    NBCi also plans to deliver value-added services to users such as content
designed specifically for broadband users, enhanced e-mail and private community
services. The following chart indicates the services to be offered by NBCi
immediately following the closing of the proposed transactions:

    After the closing of the transactions, NBCi will integrate the Xoom.com,
NBC.com, NBC-IN.com and VideoSeeker.com Web sites into the Snap.com Web site.
Users will be able to access these Web sites from the Snap.com Web site or from
the current address of each individual Web site.

    For so long as the brand integration and license agreement remains in
effect, NBCi will be the exclusive vehicle for NBC to operate a general portal
service, a broad-based community service or a broad-based e-commerce service.
The NBC relationship will offer NBCi opportunities to access content as well as
to leverage NBC's extensive and highly developed advertising relationships to
create unique ways for advertisers to reach consumers by capitalizing on
synergies between on-air and online media.

    NBCi will also enter into a multi-year television network advertising
agreement with NBC. NBCi will use the advertising to market the integrated
Snap.com Web site to Internet users, especially those with little or no
experience on the Web.

    On a pro forma basis based on data available from Media Metrix, if the
transaction had been completed on April 30, 1999, NBCi would have been the
seventh ranked site on the Internet in July 1999 based on the number of unique
users, and the fastest growing major Internet company from July 1998 to July
1999 based on the percentage increase in reach among home and work users. In
July 1999 the Internet properties to be combined in forming NBCi had an
aggregate Internet reach among home and work users of approximately 26%, with
over 16 million unique visitors, based on data available from Media Metrix. The
term "reach" means the percentage of projected individuals within a designated
demographic or market category that accessed the Web content of a specific site
or category among the total number of projected individuals using the Web during
the month.

    The total number of registered users of the Internet properties to be
combined in forming NBCi totaled over 12 million as of July 31, 1999, up from
2.5 million on July 31, 1998. For the months of June and July the average number
of users registering per day exceeded 31,000 and 28,000, respectively, for the
combined Web sites. In July 1999 the Internet properties to be combined in
forming NBCi had over 660 million page views.

    NBCi expects to have a diversified revenue stream. Had the transactions
forming NBCi been completed on January 1, 1999, NBCi would have had $33.5
million of total revenue for the six months ended June 30, 1999, 68% of which
would have been advertising revenue, 18% of which would have been e-commerce
revenue and 14% of which would have been other revenue, primarily relating to
outsourcing agreements. Pro forma revenues for the six months ended June 30,
1999 represented an increase of 282% over the pro forma revenues for the six
months ended June 30, 1998. There can be no assurance that NBCi can continue to
generate revenue from equity instruments received, which would have comprised
$10.4 million, or 29%, of total revenue for the six months ended June 30, 1999.

INDUSTRY BACKGROUND

    GROWTH OF THE INTERNET

    The Internet has emerged as a global medium, enabling millions of people
worldwide to share information, communicate and conduct business electronically.
International Data Corporation estimates that the number of Web users will grow
from approximately 97 million worldwide in 1998 to approximately 320 million
worldwide by the end of 2002. This growth is expected to be driven by the large
and growing number of personal computers installed in homes and offices, the
decreasing cost of personal computers, easier, faster and cheaper access to the
Internet, improvements in network infrastructure, the proliferation of Internet
content and the increasing familiarity with and acceptance of the Internet by
businesses and consumers. The Internet possesses a number of unique
characteristics that differentiate it from traditional media: a lack of
geographic or temporal limitations; real-time access to dynamic and interactive
content; and instantaneous communication with a single individual or with groups
of individuals. As a result of these characteristics, Web usage is expected to
continue to grow rapidly. The proliferation of users, combined with the Web's
reach and lower cost of marketing, has created a powerful channel for conducting
commerce, marketing and advertising.

                                      115
<PAGE>
    In the first few years of the development of the Internet, general portals
attracted the largest base of users as a result of the provision of search and
directory services. Over the last few years community sites have been among the
fastest growing Internet sites in numbers of users, as a result of the growing
attraction of user generated content and the desire for communication among
like-minded individuals. The nature and form of content being provided on the
Internet has also expanded dramatically as a result of an increase in the
participation of media and commerce companies conducting their businesses on the
Internet. In addition, traditional media companies have used their access to
content and promotion to create significant Web properties.

    More recently, as the number of Internet users has increased, highly focused
consumer and business sites, known as vertical hubs, have developed to attract
audiences with a particular interest. At the same time, the vertical hubs have
begun to offer their users an expanding portfolio of information and resources
and Internet portals have continued to offer increasingly deeper content on
vertical channels provided on their Web sites. Both vertical hubs and portals
are also creating their own e-commerce businesses, primarily in partnership with
e-commerce sites. These trends are expected to continue in the future.

    RECENT CONSOLIDATION OF INTERNET COMPANIES

    Over the last twelve months, Internet companies, including portals,
community and e-commerce sites, have experienced significant consolidation as a
result of increased competition for users, the desire to rapidly offer a
comprehensive set of Web services that may be more quickly acquired than built,
the need to maintain growth rates in user levels and competition for advertising
and e-commerce sales revenue.

    By providing a complete set of content, information and services, Internet
portals and communities attract a larger audience, providing a more attractive
platform for companies advertising on the Internet or attempting to develop
e-commerce businesses. Traditional media and cable companies have participated
in this consolidation using their access to content, promotion and distribution
to create significant Web properties. The cost savings realized as a result of
the elimination of overlapping services allows Internet companies to more fully
take advantage of economies of scale in their businesses. In addition, the
development of higher bandwidth distribution methods is beginning to result in
significant changes in the dynamics of business on the Internet. The development
of vertical Internet hubs focused on particular areas of interest such as
women's interests or financial topics has also accelerated the pace of
consolidation as companies seek to offer a full portfolio of products.

    The ability to compete effectively in the current environment requires
Internet companies to offer a sufficiently high level of service to attract a
strong user base, the ability to access capital and the leverage to establish
partnerships with companies offering complementary services.

THE NBCI APPROACH

    NBCi intends to expand the audience for its primary consumer brand, SNAP, as
well as the other NBCi brands by capitalizing on the demonstrated growth ability
and the leading edge technologies of the NBCi businesses, as well as NBC's
strong appeal to television viewers and consequent attractiveness to
advertisers. By offering attractive free services and content and maintaining a
large and diverse range of active communities, NBCi will encourage visitors to
its Web sites to become members of NBCi. With information provided by its
members, NBCi intends to use its proprietary consumer database to offer
advertisers and e-commerce partners the ability to deliver highly targeted
messages and product offers to NBCi's members.

    STRENGTH OF THE NBC BRAND

    NBCi will seek to expand its audience by capitalizing on the broad reach and
appeal of the NBC television network brand. With its ability to coordinate
access to the NBC television viewing audience,

                                      116
<PAGE>
NBCi intends to increase its appeal to advertisers by offering a unique
opportunity to promote sales across multiple media. According to data furnished
by Nielsen Media Research, for the television season that ended in May 1999, NBC
was the most-watched television network during primetime among adults age 18 to
54 in the United States. Primetime means 8:00 p.m. to 11:00 p.m. Monday through
Saturday and 7:00 p.m. to 11:00 p.m. Sunday. Throughout the 1998-1999 television
season, an average of more than 156 million people watched NBC television
programming at least once each week, representing more than 60% of the
population of the United States. On average, for example, a single 30-second
advertisement on the highly-rated "ER" program on NBC reached more than 22
million viewers. In addition, the results of a study commissioned by NBC from
Nielsen Media Research in 1999 indicate that during the February sweeps period
among viewers with access to the Internet, NBC primetime programming attracted
25% more viewers than the primetime programming of its nearest network
competitor, and 65% more viewers than the primetime programming of the top ten
cable networks combined.

    Since NBC acquired an equity interest in SNAP in June 1998, NBC has promoted
SNAP on the NBC television network, including sponsorship and cross-promotional
initiatives. NBCi will promote SNAP as well as other NBCi brands through the
purchase of $405 million in advertising on the NBC Television Network, CNBC,
MSNBC and NBC's owned and operated television stations over a four-year term.
NBCi and NBC have agreed to negotiate concerning the purchase of an additional
$500 million in advertising over the following six years. NBCi believes that
this promotional capability will position NBCi well to compete against the
leading diversified Internet service providers.

    USER APPEAL AND ATTRACTIVENESS TO ADVERTISERS

    NBCi will offer users a single unified Web site, Snap.com, providing search,
community, communication and e-commerce services, together with access to rich
and varied content through the vast resources of the Internet. NBCi intends to
offer a sufficient breadth of information and services to attract a large and
growing base of users, while providing sufficient depth through its multiple
relationships with content providers to maintain the interest of users seeking
very specific content. By integrating a complete set of community services
throughout the NBCi Web sites, users will be able to establish relationships
with individuals having similar interests, express themselves through
user-generated content and attract other users to the NBCi Web sites. NBCi also
plans to deliver value-added services to users by enabling them to register as
members to receive targeted offers of products and services via e-mail. By
expanding its varied offerings to users in a seamless Internet experience, NBCi
seeks to increase its user base.

    NBCi believes the ability to integrate multiple online product offerings,
and provide a breadth of detailed information on such product offerings in
combination with its ability to coordinate network advertising with NBC, will
provide cross-selling and promotional opportunities that will enable NBCi to
distinguish itself from its competitors in the Internet industry. As competition
for new Internet users intensifies and the cost of establishing a recognized
brand grows, NBCi expects that its ability to coordinate cross-promotional
opportunities with NBC will enhance the attractiveness of NBCi to advertisers by
offering exposure to a broad population of Internet users. In addition, NBCi
will have the ability to target messages using demographic data and information
on buying habits compiled by NBCi through its systems for tracking users and
managing advertising inventory. NBCi can use this information to assist
advertisers to intelligently target and monitor the effectiveness of their
presentations, as well as to offer relevant e-commerce opportunities. Through
its direct e-commerce platform and proprietary database management system, sales
opportunities can be offered through the NBCi Web sites as well as by e-mail to
the registered user base.

    DEMONSTRATED GROWTH CAPABILITY

    From July 1998 to July 1999, Snap.com and Xoom.com were two of the
fastest-growing Web sites among home and work users according to data provided
by Media Metrix. SNAP has succeeded in increasing traffic to its Web site and
recognition of its brand in part through the promotion of SNAP on the NBC
television network since NBC acquired an equity interest in SNAP in June 1998.
SNAP has also grown traffic and brand awareness through the expansion of channel
partnerships offering custom branded versions of Snap.com to over 50 Internet
service providers, PC manufacturers and other SNAP distribution partners such as
RealNetworks, GTE and Sony. Xoom.com has achieved its growth principally through
word-of-mouth marketing among its users as well as links from member Web sites
to the Xoom.com Web site.

    NBCi intends to leverage the demonstrated growth capability of Snap.com and
Xoom.com to expand brand awareness and consequently increase the member base of
NBCi. NBCi believes that it will be well positioned to strengthen awareness of
the NBCi brands, including SNAP, and thus increase online traffic and build
member loyalty as a result of the substantial levels of on-air promotional
expenditures available to the NBCi Web sites over the next four years in
comparison to the promotional expenditures of SNAP, Xoom.com and the NBC
contributed Internet assets over the past year. NBCi intends to capitalize on
Xoom.com's experience and success in expanding its user base by offering its
members a variety of compelling free services, communities and competitively
priced product offerings. In addition, by combining the strategic and financial
resources of each of Xoom.com, SNAP and the NBC contributed Internet businesses,
NBCi believes that it will be better able to compete in the rapidly
consolidating Internet services industry, and thus be better able to grow
through acquisitions, strategic alliances and joint ventures.

    LEADING EDGE INTERNET PRODUCTS AND SERVICES

    NBCi will combine leading edge Internet products and services offered by
SNAP, Xoom.com and the NBC contributed Internet businesses to offer users a rich
and varied Internet experience. Through SNAP's proprietary search technologies
and personalization capability together with its ability to offer enhanced
content such as rich media streaming, the navigation and content aggregation
services offered by NBCi are well positioned to compete with leaders in the
portal market. Snap.com For Higher Speed Users, launched by SNAP in March 1999,
uses proprietary technology to optimize users' access to rapidly evolving forms
of content including video, audio, animation and gaming. Xoom.com's array of
free user services coupled with a large and diverse range of active communities
focused on special interest categories will enable NBCi to increase its member
base. NBCi intends to leverage Xoom.com's direct e-commerce platform and
proprietary database targeting system to offer advertisers the ability to
deliver a focused, relevant message to potential consumers and targeted product
offers to the NBCi member base.

NBCI STRATEGY

    By providing a broad array of professionally created and user-created
content in a single service, NBCi intends to develop the leading site on the
Internet. NBCi continually intends to upgrade and expand Snap.com's portfolio of
services to increase the level of Internet traffic on the Snap.com Web site and
NBCi's related properties and grow NBCi's registered user base. NBCi intends to
capture relevant data on such users to provide more relevant information to
advertisers and more personalized service to its user base. NBCi plans to
accomplish these goals through the strategies discussed below.

    RAPIDLY COMPLETE THE INTEGRATION OF XOOM.COM, SNAP AND THE NBC CONTRIBUTED
     INTERNET ASSETS

    NBCi believes that a key component to its success will be its ability to
integrate the NBCi Internet businesses rapidly and cost-effectively. A number of
integration initiatives, which are expected to be

                                      118
<PAGE>
advantageous to the component companies even if the proposed NBCi transactions
are not consummated, have already been completed. SNAP search functionality is
now available on Web pages of Xoom.com and NBC.com, and Xoom.com's electronic
greeting cards and buyer's guide are accessible on Snap.com's shopping pages.
SNAP has developed technology to check user names across both Snap.com and
Xoom.com, in order to minimize potential transition problems resulting from
duplicate and multiple user names. SNAP product managers have begun mapping the
directories and sub-directories of Snap.com and Xoom.com in order to permit
their ultimate interconnection as well as understand differences in user
behavior.

    The planning process for integration of the Web sites to ensure the ease of
navigation and provide a consistent look and feel among the Web sites has
already begun. Xoom.com, SNAP and NBC have established a senior-level steering
committee to begin planning the business integration process and the potential
deployment of existing personnel should the transactions be consummated. The
businesses have also formed separate integration teams in such areas as product
development, sales and infrastructure. The integration teams report on a weekly
basis to the steering committee on the status of the planned integration and
potential problems that may occur. All planning being completed today is
designed to ensure a smooth transition following the anticipated closing of the
transactions.

    BUILD THE SNAP BRAND AND THE OTHER NBCI BRANDS

    NBCi intends to promote SNAP and the other NBCi brands through a variety of
media including television, radio, print and Internet advertising. In addition
to exposure through television advertising, NBCi expects to benefit from radio
campaigns conducted by Xoom.com and SNAP to promote their brands. NBCi will
continue this radio strategy for SNAP. NBCi believes the ability to develop a
well-recognized brand name will be critical to the long term success of the
company.

    INCREASE REVENUE AND CREATE VALUE

    NBCi intends to maximize revenue streams by focusing on a number of key
strategies, including:

    - expanding its advertising customer base through the integration of the
      NBCi businesses in the Snap.com Web site;

    - obtaining higher average advertising rates across all of the NBCi Internet
      properties and increasing the average size and length of advertising
      contracts;

    - hiring additional direct sales representatives and continuing to invest in
      improving NBCi's advertisement serving and targeting technology;

    - expanding NBCi's e-commerce product offerings and services, such as
      magazine subscriptions, appliances, games, photography supplies, home and
      auto insurance, wireless telecommunication services and membership clubs;

    - increasing margins by reducing operating costs; and

    - acquiring minority equity positions in companies with attractive growth
      opportunities.

    NBCi also intends to offer special sponsorship and events-driven promotional
advertising programs to build brand awareness, generate leads and drive traffic
to an advertiser's site. In addition, NBCi plans to sell sponsorships of special
interest pages where topically focused content is aggregated on a permanent area
within a community.

    CONTINUE TO GROW NBCI'S USER BASE

    NBCi intends to continue to expand its user base through the integration of
the NBCi Internet properties and by increasing awareness of the NBCi businesses
through the promotion of the SNAP

                                      119
<PAGE>
brand and the other NBCi brands. In addition, NBCi intends to increase traffic
to its Web sites by offering visitors attractive free services and content, and
maintaining a large and diverse range of active communities focused on special
interest categories. NBCi will also seek to acquire selected businesses to
supplement its product offerings.

    DEVELOP VERTICAL HUBS

    NBCi believes there are opportunities to selectively develop vertical hubs
in order to create an active set of users with similar interests. A vertical hub
is a website on topics of general interest such as sports, weather or health,
which is supported by professionally-created content and may contain chat rooms,
bulletin boards and e-commerce product offerings related to that particular
topic. NBCi will also seek to identify opportunities to leverage partner
relationships or selectively seek acquisitions in areas of particular value to
accomplish this goal. As opposed to a general Web audience, users with a
specific set of interests provide opportunities to sell more targeted
advertising and lead generation. Advertisers are willing to pay premium prices
to reach such targeted audiences. By providing unique content through partners
and the integration of the NBC contributed Internet businesses, NBCi intends to
develop a large database of users with common interests. A key component of this
strategy will be to leverage and build upon Xoom.com's community sites and
membership base.

    EXPAND BROADBAND INITIATIVES

    The Internet is increasingly being used as a means to distribute video and
audio content, gaming services and distributed applications. Widespread
deployment and adoption of broadband technology should accelerate the acceptance
of the Internet as an important new medium for distributing such content, as
well as next generation products with significantly more functionality and value
for users. SNAP was one of the first portals to deliver broadband content
through the Snap.com For Higher Speed Users Web site. VideoSeeker.com will
provide NBCi's users with access to streaming video content on the Web. A
Xoom.com property, The Media Sharehouse, provides a repository for user created
content. NBCi intends to seek additional opportunities to vastly expand the
nature and amount of broadband content available to its user base both through
internal development and acquisitions.

    ACCELERATE PURSUIT OF INTERNATIONAL OPPORTUNITIES

    NBCi intends to rapidly expand its platform internationally by providing the
Snap.com Web site and the other NBCi Web sites in local languages and offering
its services to local advertisers and e-commerce companies. NBCi also plans to
leverage NBC's worldwide relationships to expand its operations internationally.
The international market for Internet services is not as mature as in the United
States and opportunities exist to take a leadership position in several foreign
markets. NBCi has targeted several European and Asian countries for possible
international expansion and is currently seeking local partners to help
facilitate such expansion and provide local support in terms of personnel and
promotion.

    CONTINUE TO DEVELOP OR ACQUIRE LEADING EDGE TARGETING TECHNOLOGY AND
     SOFTWARE

    NBCi intends to continue to develop leading edge technologies to provide its
users the highest possible level of service and its advertisers and e-commerce
partners the benefit of its proprietary targeting capabilities. Areas of focus
for consumer services include broadband technologies for the delivery of
streaming video and audio, and communication tools such as e-mail, messaging and
internet telephony, among others. Advertisers currently benefit from the
integration of advertisements and product offers within search requests on
Snap.com. Xoom.com has developed a proprietary database stratification, offer
targeting and delivery system. This system uses demographic and personal
interest information provided by Xoom.com's members prior purchasing history,
along with data appended from third party providers, to determine a set of
offers most likely to appeal to individual members.

                                      120
<PAGE>
NBCi intends to expand and improve on these capabilities by continuing to invest
in the development of new technologies or by acquiring such technologies through
acquisitions or otherwise.

RECENT TRANSACTIONS AFFECTING NBCI

    On September 13, 1999, Xoom.com and SNAP entered into a strategic alliance
with ValueVision International, Inc. whereby the parties entered into
re-branding and electronic commerce agreements, including television home
shopping, Internet shopping and direct e-commerce initiatives. Under the terms
of the agreements, SNAP granted ValueVision a ten-year, exclusive license to use
SNAP's "SnapTV" trademark for the purpose of operating a television home
shopping service and a Website at www.snaptv.com in exchange for a royalty of 2%
of gross revenues received from Internet users in connection with commerce
opportunities on the SnapTV Website. ValueVision's television home shopping
network, currently called ValueVision, will be re-branded as SnapTV. The
re-branding will be phased in during late 1999 and the first half of 2000.
Xoom.com will become the exclusive direct electronic commerce partner for
SnapTV, managing all such initiatives, including database management, e-mail
marketing and other sales efforts. Direct online shopping offers will include
Xoom.com products and services, as well as SnapTV merchandise. ValueVision and
Xoom.com will share revenues from all such initiatives. ValueVision and SNAP
will roll-out a new companion Internet shopping service, SnapTV.com--featuring
online purchasing opportunities that spotlight products offered on-air along
with online-only e-commerce opportunities offered by SnapTV and its merchant
partners. In addition, SNAP will have the exclusive right to sell all Internet
advertising on SnapTV.com and will retain 50% of the revenues generated from
such advertising. The SnapTV.com online store will be featured prominently
within Snap.com's shopping area. As part of the agreements, ValueVision and
Xoom.com entered into a warrant purchase agreement whereby Xoom.com agreed to
purchase a warrant for 404,760 shares of ValueVision common stock at an exercise
price of $24.706, and ValueVision agreed to purchase a warrant for 244,004
shares of Xoom.com common stock at an exercise price of $40.983 per share. The
warrants may be exercised at any time after the closing of the contribution
agreement through September 12, 2004. In the event the transactions contemplated
in the contribution agreement do not occur by December 31, 1999, the warrants
will terminate. These rights and obligations of Xoom.com and SNAP will be
assigned to and assumed by NBCi following consummation of the transactions
contemplated in the merger agreement and the contribution agreement.

    A critical part of NBCi's success will be its ability to successfully
integrate the technology and infrastructure of Xoom.com, SNAP and the NBC
contributed Internet properties in an efficient and effective manner. The
infrastructure integration team is responsible for the integration of the
hardware and software systems of the NBCi businesses. Xoom.com and SNAP
currently use Exodus Communications, Inc. and Frontier Global Center to house
their network servers and to provide and manage power and maintain the correct
environment for their networking and server equipment. NBCi expects to continue
to use the services of these companies, which will help avoid disruption and
degradation in service to NBCi's Web sites. NBCi intends to standardize its
network and mail platforms between its principal and satellite offices. In
addition, NBCi will seek to standardize the hardware and software used by the
various NBCi businesses by making purchases through a select group of vendors.
NBCi does not presently expect to incur any material costs due to the
consolidation of vendor and supplier relationships. NBCi will continue to strive
to rapidly develop and deploy high-quality tools and features into its systems
without interruption or degradation in service. In addition, NBCi will continue
to upgrade and expand its server and networking infrastructure in an effort to
ensure fast and reliable access to its Web sites.


    The separate technology and infrastructures of Xoom.com and SNAP are
discussed on pages 146 and 183, respectively.

COMPETITION

    The market for Internet products and services is highly competitive with no
substantial barriers to entry, except that the ability to secure financial
resources necessary to promote brand awareness is increasingly becoming a
barrier to entry in the market in which NBCi intends to compete. The market for
NBCi's products and services continues to develop, is rapidly evolving and is
characterized by an increasing number of market entrants with competing products
and services. NBCi expects that competition will continue to intensify with
brand name recognition becoming an increasingly important competitive factor. To
achieve brand name recognition, Internet companies are consolidating a broad
array of products and services under a single brand. For example, recently a
number of significant acquisitions and strategic plans have been announced
involving some of NBCi's competitors, including:

    - Disney's acquiring the remaining interest in Infoseek not already owned by
      Disney;

    - AOL's acquiring Netscape;

    - @Home Networks, a provider of high-speed Internet access serving the cable
      television infrastructure and the largest stockholder of which is AT&T,
      acquiring Excite;

    - Yahoo!'s acquiring GeoCities and Broadcast.com; and

    - CMGI's acquiring 83% of AltaVista.

    These acquisitions and proposed strategic relationships will result in more
formidable competitors, some of whom are aligned with other media companies.

    A number of companies offer competitive products and services addressing
many of NBCi's target markets. These companies include Yahoo! (including
GeoCities and Broadcast.com), America Online (including AOL.com, Netcenter and
ICQ), Alta Vista, Excite@Home, Disney (including the Go Network, which is
jointly operated with Infoseek), Lycos (including Hotbot and Tripod) and
Microsoft (including msn.com). In addition, the NBCi businesses will compete
directly with a great number of other Internet sites and other media companies
across a wide range of different online services with advantages in expertise,
brand recognition and other factors, including:

    - metasearch services and software applications that allow a user to search
      the databases of several directories and catalogs simultaneously;

    - database vendors that offer information search and retrieval capabilities
      with their core database products;

    - Web-based e-mail and instant messaging services either on a stand alone
      basis or integrated into other products and media properties;

    - online merchant hosting services and the entry of an increasing number of
      companies selling goods and services on the Internet;

    - online community Web sites such as Tripod, WhoWhere, GeoCities,
      theglobe.com and iVillage;

    - online content Web sites such as ESPN.com and ZDNet.com;

    - online local interactive content Web sites, such as Excite@Home's City
      Guides, Lycos City Guides, America Online's Digital City, Ticketmaster
      Online-CitySearch and Microsoft Sidewalk;

    - online video broadcast services, such as CNN VideoSelect, RealNetworks and
      FoxNews; and

    - potential new entrants in any one or all of these areas.


    The competitive products and services for each of the separate markets under
which NBCi and the NBCi businesses will compete are described more fully on
pages 146, 183 and 203.


                                      122
<PAGE>
    Many of NBCi's existing and potential competitors have significantly greater
financial, technical and marketing resources than NBCi. NBCi may also be
adversely affected by competition from licensees of its products and technology,
and current and future advertisers, as well as from its current, future and
former content providers. There can be no assurance that NBCi's competitors will
not develop Internet products and services that are superior to those of NBCi or
that achieve greater market acceptance than NBCi's offerings. Moreover, a number
of NBCi's competitors, future advertising customers, licensees and licensors may
establish similar relationships. In addition, because of NBC's relationships
with its existing strategic partners including Microsoft and Dow Jones, NBCi, as
an affiliate of NBC, will be restricted in significant respects in its ability
to provide specific types of content and services on its Web sites, such as its
ability to provide news, including business and sports news. These restrictions
may limit NBCi's ability to compete for users by limiting the services it can
offer to meet users' needs. NBCi also competes with online services and other
Web site operators as well as traditional offline media such as print and
television for a share of advertisers' total advertising budgets. There can be
no assurance that NBCi will be able to compete successfully against its current
or future competitors or that competition will not have a material adverse
effect on NBCi's business, results of operations and financial conditions. See
"Risk Factors" on page 18.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    NBCi will view the technology of the NBCi businesses as proprietary and will
try to protect it under existing United States and international laws relating
to protection of intellectual property. NBCi intends to develop internal
procedures to control access and dissemination of its proprietary information
and will also use the existing policies and procedures of the NBCi businesses.
Despite NBCi's precautions, third parties may succeed in misappropriating its
intellectual property or independently developing similar intellectual property.
Protecting NBCi's intellectual property against infringement could result in
substantial legal and other costs and could divert NBCi's limited management
resources and attention.

    Some of the technology that will be incorporated in the SNAP Web site is
based on technology licensed from third parties. As NBCi introduces new
services, it may need to license additional technology. If NBCi is unable to
license needed technology on a timely basis and on commercially reasonable
terms, it could experience delays and reductions in the quality of its services,
all of which could adversely affect its business and results of operations.
NBCi's reputation and the value of its proprietary information could also be
adversely affected by actions of third parties to whom the NBCi businesses
license their proprietary information and intellectual property. If someone
asserts a claim relating to proprietary technology or information against NBCi
or its subsidiaries, NBCi may seek licenses to such intellectual property. NBCi
cannot assure you, however, that it could obtain these licenses on commercially
reasonable terms, if at all. The failure to obtain the necessary licenses or
other rights could have a material adverse effect on NBCi's business and results
of operations.

    Although NBCi does not believe the NBCi businesses infringe the proprietary
rights of any third parties, it cannot assure you that third parties will not
assert claims against it in the future. From time to time, the NBCi businesses
have been subject to claims of alleged infringement of intellectual property
rights of others on the basis of the actions of such businesses and the content
generated by their members and users. These categories of claims, whether or not
meritorious, could result in litigation and become a drain on NBCi's management
and financial resources. If successful, claims of this nature could subject NBCi
to liability, injunctive relief restricting its use of intellectual property
important to its operations, and could ultimately cause NBCi to lose rights to
some of its intellectual property. Any of these events could have a material
adverse effect on NBCi's business and results of operations.

EFFECT ON NBCI IF THE TRANSACTIONS CONTEMPLATED BY THE CONTRIBUTION AGREEMENT DO
  NOT OCCUR


    The following information discusses the consequences to NBCi if the
transactions contemplated by the merger agreement occur without the transactions
contemplated by the contribution agreement occurring. This discussion is
necessarily speculative in nature as Xoom.com cannot control or predict whether
the stockholders of Xoom.com will approve either or both of the transactions.


    In general, if the transactions contemplated by the contribution agreement
do not occur the surviving entity would:

    - consist of Xoom.com plus an 81% non-controlling interest in SNAP, which
      may be reduced to 40% and thereafter down to 25% if NBC Multimedia were to
      exercise its two options to purchase additional ownership interests in
      SNAP;

    - have significant influence over the operating and financing decisions of
      SNAP, but would not control SNAP because of the governance rights shared
      by the surviving entity and NBC;

    - not be affiliated with NBC other than through their shared ownership of
      SNAP;

    - not enter into an advertising agreement with NBC;

    - not have access to NBC's name, trademarks or the NBC contributed Internet
      properties; and

    - not have the right to use "NBC" in its name.

The proposed Class B Directors, including John F. Welch, Jr., would not serve as
directors of the surviving entity and Robert C. Wright would not serve as its
chairman of the board. In addition, the employees of SNAP would hold options in
the surviving entity even though the surviving entity would not own a
controlling interest in SNAP.


    The current stockholders of Xoom.com are expected to own approximately 74.4%
of the outstanding shares of the surviving entity and CNET is expected to own
approximately 25.2% of the outstanding shares. However, as discussed beginning
on page 90, if the stockholders of Xoom.com fail to approve the adoption of the
contribution agreement after a third party has made a bona fide proposal to
Xoom.com or its stockholders to engage in an acquisition transaction, NBC could
exercise its option to purchase approximately 19.9% of the common stock of
Xoom.com, which would dilute the ownership interests of Xoom.com's current
stockholders.


    Although Xoom.com has not developed a formal business plan that addresses
the future operations of the surviving entity without the transactions
contemplated by the contribution agreement occurring, it expects that the
surviving entity would:


    - not be able to integrate the operations of Xoom.com and SNAP as fully as
      is currently contemplated, because the surviving entity would not hold a
      controlling interest in SNAP;


    - promote Xoom.com instead of SNAP as its primary consumer brand over a
      variety of media, but to a significantly lesser extent than that planned
      currently for NBCi;

    - seek to develop relationships with SNAP, including entering into operating
      agreements that would govern their strategic relationships; and

    - seek to increase its user base by offering leading edge Internet products
      and services, selectively developing vertical hubs, expanding broadband
      content available to users and expanding internationally.

    Xoom.com may in addition consider other possible strategic relationships
with NBC in the future. Xoom.com expects that the surviving entity would have
sufficient capital resources to fund its operations for the twelve months
following the closing of the merger agreement. Thereafter, if cash

                                      124
<PAGE>
generated from operations is insufficient to satisfy its liquidity requirements,
the surviving entity may need to sell additional equity or debt securities or
obtain other forms of financing.

LEGAL PROCEEDINGS


    As a newly formed company, NBCi is not subject to any pending or threatened
litigation. NBCi's operations and financial performance, however, may be
affected by pending litigation against Xoom.com and SNAP. See pages 147 and 184
and "Risk Factors" on page 18.


EMPLOYEES

    Upon consummation of the transactions, NBCi will have approximately 500
full-time employees, including 215 in sales and marketing, 195 in operating and
product development and 90 in finance and administration. All of these
individuals are currently employees of Xoom.com, SNAP and NBC and its
affiliates. The future success of NBCi will depend, in part, on its ability to
continue to attract, retain and motivate highly qualified technical and
management personnel, for whom competition is intense. From time to time, NBCi
will employ independent contractors to support its research and development,
marketing, sales and support and administrative organizations. NBCi's employees
are not covered by any collective bargaining agreement.

FACILITIES

    Upon consummation of the transactions, the current operations of SNAP and
Xoom.com will be consolidated at Xoom.com's newly leased facilities in San
Francisco, California, which will serve as NBCi's headquarters. NBCi will also
employ some of the persons formerly employed by NBC Multimedia at NBC
Multimedia's facilities. NBCi also intends to consolidate the East Coast
operations of Xoom.com and SNAP into Xoom.com's office space in New York, New
York.

DISCLOSURES ABOUT MARKET RISK

    NBCi's exposure to market risk is expected to be confined principally to its
short-term available-for-sale securities, which have short maturities and,
therefore, minimal and immaterial market risk. NBCi expects to invest in equity
securities of privately held companies for business and strategic purposes. For
investments in which no public market exists, NBCi's policy will be to regularly
review the operating performance, recent financing transactions and cash flow
forecasts for such companies in assessing the net realizable values of the
securities of these companies. NBCi expects to identify and record impairment
losses on long-lived assets when events and circumstances indicate that such
assets might be impaired.

                   MANAGEMENT OF NBCI FOLLOWING TRANSACTIONS


    Upon the closing of the transaction, the authorized number of directors of
NBCi will be thirteen. Initially, NBC shall have the right to designate six
directors, each referred to as a "Class B Director", Xoom.com shall have the
right to designate six directors, each referred to as a "Class A Director" and
NBC and Xoom.com shall mutually agree on the designation of the thirteenth

STOCK INCENTIVE PLAN

    The material terms of the stock incentive plan are described beginning on
page 99.

401(k) PLAN

    Each of Xoom.com and SNAP has a 401(k) plan, pursuant to which eligible
employees may elect to reduce their current salary by up to the statutorily
prescribed annual limit and have the amount of such reduction contributed to the
401(k) plan. Neither plan provides for a matching contribution from the
employer. Both of the 401(k) plans are intended to qualify under Section 401 of
the Internal Revenue Code so that contributions to the 401(k) plan, and income
earned on plan contributions, are not taxed until withdrawn from the 401(k)
plan. Initially after the transaction, each of Xoom.com and

                                      130
<PAGE>
SNAP will keep its 401(k) plan in place. NBCi may consolidate the two plans into
a single plan for the combined group of companies. No such change will reduce
benefits earned prior to the effective date of the change.

WELFARE BENEFIT PLANS

    Each of Xoom.com and SNAP maintains a comprehensive program of health,
dental, vision care, disability and life insurance for its employees. Generally,
participation in these plans is available to all full-time employees after a
qualification period. Initially after the transaction each of Xoom.com and SNAP
will keep its welfare benefit plans in place. NBCi may consolidate the plans
into a single plan for the combined group of companies. No decision has been
made as to the terms and form of such combined plans.

                               XOOM.COM BUSINESS

OVERVIEW

    Xoom.com is one of the fastest growing community based Web sites based on
the percentage increase in reach among home and work users. Xoom.com attracts
members to its community site with a variety of free services, including
homepages, e-mail, chat rooms, electronic newsletters, clip art and software
libraries, page counters, online greeting cards and media storage. Xoom.com's
members can also join topical communities where they can exchange ideas and
information. Members may also enter specialized forums such as Investor Place,
Women's Circle or Health & Fitness, where they can gain access to professional
content and special product and service offers available only on Xoom.com's Web
site. Upon registration, members agree to receive periodic offers of products
and services via e-mail. These competitively priced and continuously updated
offers include computer software, computer accessories and peripherals, consumer
electronics, clip art on CD-ROM and collectible items. In addition, Xoom.com
offers services such as a travel club, long distance telephone services and a
DVD club. Xoom.com's new offerings will include services such as home and auto
insurance, wireless telecommunications services and membership clubs, and
products such as magazine subscriptions, appliances, games, photography supplies
and gardening tools, among others. Xoom.com believes that its rapidly growing
base of self-qualified members provides it with highly attractive e-commerce
opportunities. In addition, Xoom.com believes that its high levels of traffic
and the number of unique users that visit its site or affiliated sites on which
Xoom.com offers services on a monthly basis present an attractive platform for
advertising.

    According to Media Metrix, Xoom.com was the seventeenth most visited site on
the Internet in July 1999, and its reach among home and work users increased to
13.8% in July 1999 from less than 3% in January 1998. In June 1999, the Xoom.com
site and Xoom.com's network of chat rooms and page counters had a total reach
among home and work users of 31.3%, according to Media Metrix. Xoom.com had
approximately 9.8 million members as of August 30, 1999, adding an average of
approximately 24,000 new members per day for the last 30 days. Xoom.com believes
that its ability to achieve a high level of reach and membership with minimal
investment gives it a significant advantage as its e-commerce and advertising
businesses expand. In the quarter ended June 30, 1999, Xoom.com delivered
approximately 50% of its net revenue from e-commerce and approximately 13% of
net revenue from non-U.S. sales. E-commerce revenue consists of the sale of
products and services over the Internet, net of returns and inclusive of
outbound shipping and handling fees. Quarterly net revenue increased from
approximately $1.7 million in the second quarter of 1998 to $6.5 million in the
second quarter of 1999, representing compound quarterly sales growth of
approximately 40%. Quarterly net losses were approximately $2.3 million and $6.7
million in the second quarter of 1998 and 1999, respectively.

COMMUNITY AND E-COMMERCE INDUSTRY BACKGROUND

    THE GROWTH OF ONLINE COMMUNITIES AND OTHER FREE INTERNET SERVICES

    Traditional use of the Web has consisted largely of one-way communications
in which users "surf" and view different Web sites containing
professionally-created content on topics of general interest such as news,
sports and weather. However, there is a growing demand for online community
sites where users can publish content and engage in community activities
including home page building, chat and discussion forums. In addition, many
users are interested in gaining access to other free services for entertainment,
such as interactive games or streaming video, or for their utility to the end
user, such as e-mail or greeting cards. Online communities provide a medium for
such access and interaction. Communities generate significant volumes of
traffic, as visitors tend to return to those sites where they have established
an online presence or have become familiar with the services. According to
statistics

                                      137
<PAGE>
published by Media Metrix, online community sites have recently been one of the
fastest growing sectors of the Web.

    COMMUNITY, E-COMMERCE AND ADVERTISING

    The growing adoption of the Web represents a significant opportunity for
businesses to conduct commerce over the Internet. The Internet allows companies
to develop one-to-one relationships with customers worldwide without making
significant investments in traditional infrastructure such as retail outlets,
distribution networks and sales personnel. The Internet is an increasingly
significant global medium for e-commerce. According to IDC, transactions on the
Internet are expected to increase from approximately $32 billion in 1998 to
approximately $426 billion in 2002, with the number of users that are buyers of
products and services rising from 26% to 40% in the same period.

    Increases in consumer purchases on the Internet are expected to be a
significant factor in the growth of e-commerce. Online shopping is a shopping
experience that offers convenience to the shopper. An online consumer's ability
to comparison shop is greatly enhanced by the ability to access multiple
retailers via the Internet. Products commonly sold on the Internet included
items such as software, books, music CDs, videocassettes and airline tickets.
More recently, as Internet usage and familiarity has increased, businesses have
begun selling specialty retail products, service items and large ticket
household consumer goods.

    According to Forrester Research, total online retail sales in the U.S. are
expected to increase from $7.8 billion in 1998 to $108 billion in 2003.
Forrester Research also projects that the number of U.S. households that shop
online will reach 40 million in 2003.

    Online community sites provide more detailed demographic data and
self-selected groups of consumers with an affinity for particular products.
Advertisers can thus more easily deliver targeted messages in a cost-effective
manner. Growth in the Web has also created an important new advertising channel.
Tools not available in traditional advertising media, such as real-time
measurement of "click-through" on advertising banners, further increase the
attractiveness of Web advertising by giving advertisers instant feedback on
campaigns. Jupiter Communications projects that the dollar value of advertising
on the Web is expected to increase from approximately $1.9 billion in 1998 to
approximately $7.7 billion in 2002.

    THE DIRECT E-COMMERCE OPPORTUNITY ON THE INTERNET

    The same advantages that facilitate the growth of e-commerce and advertising
make the Internet a compelling medium for direct e-commerce campaigns. Direct
e-commerce over the Internet uses e-mail to reach potential buyers worldwide,
potentially offering them a significantly broader selection of products and
services than is available locally. Internet-based direct e-commerce also allows
marketers to rapidly collect meaningful demographic information from consumers
and to use this information to target their direct e-commerce campaigns.
Further, the costs of direct e-commerce via e-mail are dramatically lower than
those of traditional direct e-commerce techniques. As a result, Internet-based
direct e-commerce campaigns can be profitable at response rates that are a
fraction of the rates for traditional campaigns.

APPROACH

    Xoom.com uses the unique characteristics of the Web to cost-effectively
market products and services to its rapidly growing member base. Xoom.com
believes it has created an innovative online sales channel with low customer
acquisition costs. The key elements of Xoom.com's approach are:

    COST-EFFECTIVE DIRECT E-COMMERCE CAPABILITY

    Xoom.com applies a sophisticated direct e-commerce approach, modeled after
traditional direct mail campaigns, to generate product sales. Unlike traditional
direct e-commerce campaigns, which typically use paper-based promotional
materials delivered by mail, Xoom.com's campaigns use regular e-mails to
communicate offers to members, significantly reducing the cost of reaching the
consumer. The interactive nature of the Web and the ability to display
attractive graphics to users clicking through on product offerings enables
Xoom.com to present such offerings in a more complete and dynamic manner than
allowed by paper-based delivery systems.

    RAPID FORMULATION OF EFFECTIVE DIRECT E-COMMERCE CAMPAIGNS

    Prior to introducing new product offerings to its entire membership base,
Xoom.com selects a subset of members for the purpose of test-marketing a
campaign. Xoom.com has developed campaign-management software that uses
statistical techniques to analyze a test campaign and to predict the expected
response rate to such a campaign if it is rolled out to a larger group of
members. Xoom.com can also analyze the effects of variations in price, graphics
and copy. Results are usually available in less than one day. On the basis of
these tests, Xoom.com selects product offers for a larger audience and modifies
them to maximize response rates, sales, profitability and member retention.
Testing also increases the accuracy of Xoom.com's forecasts of product demand.
As a result, Xoom.com is typically able to carry small amounts of inventory,
thus lowering overhead and the risk of write-offs.

    DIVERSE PRODUCT OFFERINGS AND MULTIPLE E-COMMERCE CHANNELS

    Because of Xoom.com's relationship with its members, Xoom.com is able to
offer a wide variety of product and service offerings to its members under the
Xoom.com brand name. Xoom.com is also able to reach its members with offers
through multiple direct e-commerce channels. In addition to offers via e-mail,
members may purchase products through various themed areas on the Xoom.com site
such as Investor Place and Health & Fitness and, beginning in the second quarter
of 1999, through other sites controlled by Xoom.com such as the Xoom.com
shopping channel.

    PROVISION OF FREE SERVICES TO ATTRACT A GROWING MEMBERSHIP BASE

    Xoom.com offers its members a variety of free services, including home
pages, e-mail, chat rooms, electronic newsletters, clip art and software
libraries, page counters and online greeting cards. Xoom.com provides its
members with unlimited disk space on its servers to develop personal Web sites
or to use as personal Web storage space. Xoom.com also allows members to access
proprietary software in order to create a Web page quickly, as well as
ready-made multimedia tools that can be used to develop a fully-customized,
content-rich site. Members can join one or more of over 200 communities free of
charge. Members also promote their Web sites elsewhere on the Internet, using
hyperlinks on other individual sites as well as listings on directories and
search engines, resulting in millions of new visitors to the Xoom.com site.
Xoom.com believes that providing free services is critical to maintaining
membership growth.

    DEVELOPMENT OF A DETAILED MEMBER DATABASE

    To date, Xoom.com has gathered a significant base of information about its
members through registration information, responses to promotional campaigns and
purchasing information obtained

                                      139
<PAGE>
from third parties. As more members join Xoom.com, participate in its topical
communities and use Xoom.com's other free services, and as Xoom.com obtains
additional purchasing history data, the level of information about its members
will continue to grow. Xoom.com intends to use this growing database to target
offers, increase the range of product offerings and encourage future
transactions and involvement with the Xoom.com site.

    ATTRACTIVE ADVERTISING PLATFORM

    Xoom.com's approach creates high volumes of traffic, enabling business
advertisers to cost-effectively promote their products and services on the
Xoom.com site. Xoom.com's community structure and registration data provide
valuable demographic information and affinity-based member segmentation that
increase advertisers' ability to target campaigns. Further, the diversity of
interest groups among members creates potential markets for a broad range of
products and services, resulting in a correspondingly broad range of advertising
customers.

STRATEGY

    Xoom.com's objective is to be a leading direct e-commerce company on the
Internet. Historically, key strategies to achieve this objective include:

    FOCUS ON MEMBERSHIP GROWTH

    Xoom.com has driven significant membership levels by providing attractive
free services and content, maintaining a large and diverse range of active
communities, using Web-based promotion to attract new members and offering
special incentives and promotions.

    CONVERT MEMBERS TO BUYERS THROUGH NEW INITIATIVES

    Xoom.com has used its proprietary database marketing technology and other
e-commerce channels to effectively convert reach into e-commerce revenue.
Xoom.com's goal is to foster user loyalty and encourage users to take advantage
of Xoom.com's services in their future e-commerce transactions. Xoom.com has
worked to develop incremental channels of e-commerce, thereby enhancing the
Xoom.com database and increasing the number of members qualified to receive
relevant direct product offers.

    CONTINUE TO OFFER NEW PRODUCTS AND SERVICES

    In addition to its primary product offerings such as computer software,
computer accessories and peripherals, consumer electronics and clip art on
CD-ROM, Xoom.com has introduced a DVD movie club, gift items, health related
products, a travel club, long distance services and personal finance
newsletters, among other products.

    EXPAND INTERNATIONALLY

    For the year ended December 31, 1998, international sales comprised 25% of
Xoom.com's total net revenue and 31% of e-commerce revenue. Xoom.com believes
that it is particularly well-positioned to benefit from international sales
growth because, unlike traditional retailers, Xoom.com is not encumbered with an
international distribution infrastructure that can depress margins. In February
1999, in partnership with WebNext s.r.l., an Italian corporation, Xoom.com
launched its Italian site, Xoom.it, the first of Xoom.com's international
partnerships, and is currently targeting several other European nations for
further expansion.

<PAGE>
    PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES

    Xoom.com has entered into a number of acquisitions, license arrangements and
strategic alliances in order to build its membership base and services, provide
community-specific content, generate additional traffic and establish additional
sources of net revenue. Xoom.com intends to continue making acquisitions to
increase reach and membership and to seek additional strategic alliances with
content and distribution partners, including alliances that create co-branded
sites through which Xoom.com markets its services.

    USE DATABASE EXPERTISE TO GAIN ACCESS TO MEMBERS OF THIRD PARTY SITES

    Xoom.com currently manages e-mail databases containing a total of
approximately four million names on behalf of third party sites in exchange for
the right to conduct direct e-commerce campaigns to the members of those sites.
Xoom.com generally shares the revenue generated through direct offers with the
partner site. Xoom.com intends to use its expertise in direct e-commerce to
increase the number of e-mail addresses under management and the number of
individuals receiving offers from Xoom.com.

    DEVELOP LEADING EDGE TARGETING TECHNOLOGY AND SOFTWARE

    Xoom.com has developed a proprietary, sophisticated database stratification,
offer targeting and delivery system. The system allows Xoom.com to determine a
set of offers most likely to appeal to individual members. Xoom.com intends to
continue to enhance and upgrade its database marketing technology and software
to provide more relevant offers to its members.

    INCREASE ADVERTISING REVENUE

    Xoom.com intends to increase advertising revenue by focusing on a number of
key strategies, including expanding its advertising customer base, increasing
advertising rates, page views and the average size and length of advertising
contracts, hiring additional direct sales representatives and continuing to
invest in improving its advertisement serving and targeting technology.

PRODUCTS AND SERVICES

    Xoom.com's business model creates a diverse range of communities and a
critical mass of members with whom to interact. Xoom.com provides each member
with unlimited disk space on its servers and the use of powerful Web publishing
tools for the rapid creation of a personalized Web site. Additionally, Xoom.com
offers members free e-mail, chat, page counters, online clip art, electronic
newsletters and online greeting cards, as well as excellent customer service and
high-quality site performance. Members can participate in one or more of over
200 communities and set up direct links to their personal Web sites, allowing
them to take advantage of Xoom.com's services without the need to access the
Xoom.com site directly.

    HOW VISITORS BECOME MEMBERS

    To become a member, a visitor must provide a valid e-mail address as well as
permission to be re-contacted with targeted news and product offers by e-mail. A
new member can then use one or more of our free services, such as building a Web
page, joining a community or sending an online greeting card, or can purchase
products at a discount. Xoom.com's services are designed so that their use
attracts new members. For example, online greeting cards contain a message that
informs the recipient of the card's origins and provides information on how the
recipient can learn more about Xoom.com and become a member. Xoom.com also
encourages members to link their Web sites and communities to users outside of
Xoom.com, thereby increasing Xoom.com's visibility among potential members.

<PAGE>
    CONVERTING MEMBERSHIP INTO E-COMMERCE REVENUE

    Following membership registration, Xoom.com sends the new member an e-mail
with password and membership confirmation, along with an initial product offer.
Thereafter, Xoom.com sends the member an e-mail approximately once a week,
containing product offerings or informational newsletters. Each e-mail contains
directions for removal from Xoom.com's address list, should the member wish to
stop receiving offers. Product offers are made to members worldwide using direct
e-commerce techniques. Currently, Xoom.com typically makes product offers to its
entire membership base or target segments of its membership based on the Web
services they use. As Xoom.com includes additional purchasing history and third
party data in its member database, Xoom.com believes it will be able to target
consumers having an affinity for specific products and services effectively.
Frequent directed e-mail offers, combined with ease of ordering, provide a
context for on-demand purchases of products and services. The following chart
details Xoom.com's major product and service offerings for the year ended
December 31, 1998 and approximate prices for each category:

    XOOM.COM BUYER'S CLUB AND LIST PARTNERING

      Channel in the United States. In exchange, Xoom.com will have the
      exclusive right to send direct advertising and marketing to members of the
      Web sites. Additionally, Xoom.com will purchase at least $3.5 million per
      year of advertising on the Clear Channel radio network and billboards.

      auction site. FairMarket provides all of the hardward, software and
      support associated with the Xoom.com auction site.

    - MYPOINTS.COM, INC. Xoom.com has entered into an agreement with
      MyPoints.com, a leading provider of Internet loyalty reward solutions,

    Xoom.com's strategic alliances are under agreements with a duration of one
year or less. Although Xoom.com views its strategic relationships as a key
factor in its overall business strategy, it is not certain that the strategic
partners will view their relationships with Xoom.com as significant to their own
business or that they will not reassess their commitment to Xoom.com in the
future. In addition, it is possible that one of the strategic partners will
break its agreement with Xoom.com, and Xoom.com might not be able to
specifically enforce the terms of the agreement. Xoom.com's arrangements with
strategic partners generally do not establish minimum performance requirements
for the strategic partners but instead rely on their voluntary efforts. In
addition, most of the agreements with strategic partners may be terminated by
either party with little notice. Therefore, there is no guarantee these
relationships will be successful. In the event that a strategic relationship is
discontinued for any reason, Xoom.com's business, results of operations and
financial condition may be materially adversely affected. In addition, Xoom.com
cannot guarantee that Xoom.com will be successful in establishing additional
strategic relationships.

SALES AND MARKETING

    Xoom.com's sales and marketing strategy is designed to strengthen awareness
of the Xoom.com brand, increase online traffic, build member loyalty, maximize
repeat purchases, increase the size and frequency of e-commerce transactions and
develop additional revenue opportunities.

    MARKETING THE XOOM.COM SITE

    Historically, Xoom.com has marketed its services primarily by word-of-mouth
and indirect promotions by members with links to the Xoom.com site and through
the use of Xoom.com's services. Xoom.com believes that such relationship
marketing will continue to generate a substantial amount of additional traffic
and new members.

    In the future, Xoom.com expects to develop other cost-effective methods of
marketing the Xoom.com brand through relevant media, potentially including
print, radio and television. All promotions will be designed to increase traffic
and brand awareness of the Xoom.com name. Xoom.com also intends to introduce a
number of other brand awareness and membership retention programs on its Web
site to make use of Xoom.com's large and growing member base and visitor
traffic.

    PRODUCT MARKETING

    Xoom.com applies a sophisticated direct e-commerce program to generate
product sales. As Xoom.com gathers additional information about its members,
Xoom.com intends to further target its offers and increase its range of product
offerings. Xoom.com uses its marketing campaign-management software to
efficiently test-market potential product offers. On the basis of these tests,
Xoom.com selects product offers for a larger audience and tests price to
maximize response, sales or profitability. Tests also allow Xoom.com to
structure campaigns that maximize member retention.

    ADVERTISING

    Xoom.com has a direct sales organization, located in New York and San
Francisco, that is dedicated to developing and maintaining close relationships
with top advertisers and leading advertising agencies nationwide. As of August
31, 1999, Xoom.com had 24 employees in its direct sales organization. From time
to time, Xoom.com also enters into arrangements with a number of third-party
advertising sales representatives, although, as of August 31, 1999, Xoom.com had
no such arrangements. Xoom.com's sales organization is focused solely on selling
advertising on all Xoom.com properties. Xoom.com's sales organization consults
regularly with advertisers and agencies on design and placement of their
Web-based advertising, provides advertisers with advertising measurement
analysis and focuses on providing a high level of customer service and
satisfaction.

    Advertisers and advertising agencies typically enter into short-term
agreements, of an average of one to two months in duration, under which they
receive a guaranteed number of impressions, i.e., the

                                      144
<PAGE>
number of times an advertisement is seen by a user, for a fixed fee. Xoom.com
has experienced, and expects to continue to experience, a variable renewal rate
for its advertising contracts. Advertising on the Xoom.com site currently
consists primarily of banner-style advertisements that are prominently displayed
at the top of pages on a rotating basis throughout the Xoom.com site. From each
banner advertisement, viewers can directly access the advertiser's own Web site
through a hyperlink, thus providing the advertiser an opportunity to directly
interact with an interested customer. Xoom.com's standard rate card cost per
thousand impressions for banner advertisements currently ranges from $8 to $12,
depending upon location of the advertisement and the extent to which it is
targeted for a particular audience. Xoom.com may provide discounts from standard
rates for higher volume, longer-term advertising contracts.

    ADVERTISING SPONSORSHIPS

    Xoom.com has signed a number of long-term sponsorships of a minimum of six
months duration as a result of the growth in reach of the Xoom.com site and the
desire of advertisers to reach Xoom.com's membership and user base. Such
sponsorships generally provide for specific placement on the Xoom.com site and
the delivery of a minimum number of impressions over the course of the contract.
Xoom.com has signed such agreements with Beyond.com, eBay, Job Options and NECX,
among others.

    ADVERTISING CUSTOMERS

    During the twelve months ended December 31, 1998, Xoom.com had approximately
133 advertisers on its Web site. For the year ended December 31, 1998,
Xoom.com's five largest advertising customers, GoTo.com, About.com, Maaznet
Directory Services, NECX and Yoyodyne Entertainment, accounted for approximately
35% of advertising revenue (approximately 9% of total net revenue). The
following is a list of our top 15 advertising customers by net revenue for the
year ended December 31, 1998:

</TABLE>

CUSTOMER SERVICE AND SUPPORT

    Xoom.com believes that the strength of its customer service and technical
support operations is critical to Xoom.com's success in maintaining its
membership base, increasing membership and encouraging repeat usage and
purchases. Xoom.com has established a team of customer service and technical
support professionals who process inquiries and monitor the status of orders,
shipments and payments, operating from 7 a.m. to 6 p.m. Pacific time Monday
through Friday. Members can access customer service by e-mail and through a
toll-free telephone number. Xoom.com intends to enhance and automate the e-mail
response portions of its customer service and technical support operations in
the near future.

WAREHOUSING AND FULFILLMENT

    Xoom.com has no fulfillment operation or warehouse facility of its own, and
currently relies primarily on Banta for warehousing and fulfillment services. As
a result of its product testing, Xoom.com does not generally carry large amounts
of inventory of any given product. Most shipments are made from Banta's
warehouse in Orem, Utah. In the event that Xoom.com's product sales increase
substantially, particularly abroad, Banta has facilities within and outside of
the United States that can handle additional shipment and warehousing needs.

    Xoom.com uses automated interfaces for accepting, sorting and processing
orders to enable it to achieve the most rapid and economical purchase and
delivery terms. Xoom.com processes

                                      145
<PAGE>
approximately 95% of orders online, with the remainder by telephone, fax or
mail. Once Xoom.com receives an order, Xoom.com sends a confirmation by e-mail
to the customer. At the end of each day, Xoom.com sends orders to Banta or to
other suppliers for processing. When Xoom.com sends orders to Banta, Banta
provides confirmation to Xoom.com along with shipping information for all
ground-shipped U.S. orders. International orders through Banta are sent by
international air mail. Xoom.com forwards shipping information by e-mail to
customers.

TECHNOLOGY AND INFRASTRUCTURE

    Xoom.com has developed an open standard hardware and software system that is
designed for reliability. System architecture is based on a distributed model
that is highly scalable, flexible and modular, emphasizing extensive automation
and a high degree of redundancy that is designed to minimize single points of
failure. The system integrates site management, network monitoring, quality
assurance, transactions processing and fulfillment services. Currently, the
system has 2.5 terabytes of unformatted disk space and has a peak bandwidth of
over 200 megabits per second.

    Xoom.com uses network servers that are housed separately by application at
Exodus Communications, Inc. in Santa Clara, California and Frontier Global
Center in Sunnyvale, California, third-party and public domain server software
that Xoom.com has optimized internally, and internally developed tools and
utilities. Requests for files are distributed to the appropriate servers using
load distribution and balancing hardware. Xoom.com also employs in-house
monitoring software that includes automated diagnostic programs and intelligent
agents that test and measure system response, create reports for evaluation by
technical staff and generate pager calls in the event of system failures.
Additional software monitors abuse of the site by members and potential hackers.
Reporting and tracking systems generate daily membership, order and campaign
reports. Membership and mailing engines allow for efficient deployment of member
data and targeting of e-mail campaigns.

    Xoom.com stores member-generated content on a redundant array of independent
disks. Xoom.com stores member profile information on multiple disk arrays using
Oracle database software and backs it up on long-term tape storage devices on a
daily basis. Xoom.com will continue to upgrade and expand its server and
networking infrastructure in an effort to improve Xoom.com's fast and reliable
access to its Web site and communities. Any system failure that causes an
interruption in service or a decrease in responsiveness of the Xoom.com Web site
could result in less traffic on the Web site and, if sustained or repeated,
could impair Xoom.com's reputation and the attractiveness of its brand.

    Xoom.com's site is connected to the Internet via multiple links on a 24
hour-a-day, seven days per week basis by Exodus and Frontier Global Center.
Exodus and Frontier Global Center also provide and manage power and maintain the
correct environment for Xoom.com's networking and server equipment. Xoom.com
manages and monitors servers and networks remotely from its headquarters in San
Francisco, California. Xoom.com strives to rapidly develop and deploy
high-quality tools and features into its system without interruption or
degradation in service. Any disruption in the Internet access provided by Exodus
or Frontier Global Center, or any interruption in the service that Exodus or
Frontier Global Center receives from other providers, or any failure of Exodus
or Frontier Global Center to handle higher volumes of Internet users to the
Xoom.com site could have a material adverse effect on Xoom.com's business,
results of operations and financial condition.

COMPETITION

    The market for community-based direct selling channels on the Internet is
new and rapidly evolving. Competition for members, consumers, visitors and
advertisers is intense and is expected to increase over time. Barriers to entry
are relatively low. Other companies that are primarily focused on creating
Web-based communities on the Internet and with whom Xoom.com competes are Tripod
and WhoWhere, subsidiaries of Lycos, GeoCities, recently acquired by Yahoo!, and
theglobe.com. Xoom.com also faces competition from, and competes for visitors
and traffic with, Web directories, search engines, shareware archives, content
sites, online service providers, and traditional media

                                      146
<PAGE>
companies such as Disney (including ABC and ESPN), America Online (including
Netscape), CBS, Excite@Home, Infoseek, Lycos, Microsoft, Time Warner and Yahoo!.

    Xoom.com also expects intense competition in the e-commerce market from an
ever increasing number of companies selling goods and services over the
Internet, particularly goods and services that relate to the use of computers.
These competitors include:

    - traditional computer retailers including CompUSA and Micro Electronics'
      MicroCenter;

    - various mail-order retailers including CDW Computer Centers, Micro
      Warehouse, Insight Enterprises, Inc., PC Connection, Inc. and Creative
      Computers;

    - Internet-focused retailers including Amazon.com, Egghead's Egghead.com,
      software.net, and New England Circuit Sales' NECX Direct;

    - manufacturers that sell directly over the Internet including Dell
      Computer, Gateway 2000, Apple Computer and many software companies;

    - a number of online service providers including America Online and the
      Microsoft Network that offer computer products directly or in partnership
      with other retailers;

    - some non-computer retailers such as Wal-Mart Stores that sell a limited
      selection of computer products in their stores; and

    - computer products distributors that may develop direct sales channels to
      the consumer market.

    Increased competition from these and other sources could require Xoom.com to
respond to competitive pressures by establishing pricing, marketing and other
programs or seeking out additional strategic alliances or acquisitions that may
be less favorable to Xoom.com than it could otherwise establish or obtain, and
thus could have a material adverse effect on Xoom.com's business, prospects,
financial condition and results of operations.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    Xoom.com's success depends significantly upon its proprietary technology.
The nature of Xoom.com's intellectual property protections and the associated
risks faced by Xoom.com are substantially similar to those discussed above with
respect to NBCi on page 123.

LEGAL PROCEEDINGS

    Xoom.com is litigating a dispute with Imageline, Inc., which claims to own
the copyright in some of the clip art images licensed to Xoom.com by Sprint
Software Pty Ltd, an unrelated third party. Some of the disputed images were
included in versions of Xoom.com's Web Clip Empire CD-ROM product licensed by
Xoom.com to third parties, including other software clip publishers. The images
licensed from Sprint Software generated less than 1.0% of Xoom.com's total net
revenue in 1998, and since September 30, 1998, Xoom.com has not received any net
revenue for images licensed from Sprint Software.

    To resolve this matter, Xoom.com filed a lawsuit against Imageline in August
1998 in the United States District Court for the Eastern District of Virginia.
Xoom.com asked for a declaration with respect to Imageline's allegations of
copyright infringement regarding the clip art images. In September 1998
Imageline filed a counterclaim, which they amended in January 1999, seeking up
to $60 million in damages. In March 1999, the parties completed the discovery
process and filed separate motions for partial summary judgment. On April 5,
1999, the court granted one of Xoom.com's motions for partial summary judgment
and stayed the case to allow Imageline to file all necessary copyright
registration applications to cover the clip art images.

    Xoom.com believes that the claims asserted in Imageline's counterclaim are
without merit and continues to defend against them vigorously. As part of the
lawsuit, Xoom.com is seeking to enforce its right to indemnification under its
license agreement with Sprint Software for any damages that may be imposed on
Xoom.com. Xoom.com does not know whether Sprint Software will be able to fulfill
its indemnity obligations. Depending on the outcome of the litigation, Xoom.com
may also need to

                                      147
<PAGE>
indemnify third parties for damages in connection with the use of the Imageline
images. An unfavorable outcome to this litigation could adversely affect
Xoom.com's business and results of operations.

    Zoom Telephonics, Inc. filed a lawsuit against Xoom.com in September 1998 in
the United States District Court for the District of Massachusetts alleging
trademark infringement and related statutory violations. Xoom.com was not served
with Zoom Telephonics' complaint until January 1999. Zoom Telephonics has
demanded that Xoom.com stop using the Xoom.com trademark and has asked for an
unspecified amount of money damages. Xoom.com responded to the complaint in
February 1999. In April 1999, Zoom Telephonics filed a motion for preliminary
injunction to stop Xoom.com from using any mark containing "Xoom". Xoom.com has
filed a motion to oppose Zoom Telephonic's motion for preliminary injunction. A
hearing on the motion for preliminary injunction was held on September 30, 1999.
On October 7, 1999, the court denied Zoom Telephonics motion for a preliminary
injunction, but allowed Zoom Telephonics to request the court to reconsider the
motion if the Xoom.com merger does not close by October 31, 1999. Xoom.com
believes that the claims asserted by Zoom Telephonics are without merit and
intends to defend against them vigorously. Xoom.com cannot assure you, however,
that the results of this litigation will be favorable to Xoom.com. An adverse
result of the litigation could have a material adverse effect on Xoom.com's
business and results of operations, particularly if the litigation forces
Xoom.com to make substantial changes to its name and trademark usage. Any name
change could result in confusion to consumers and investors, which could
adversely affect the results of Xoom.com's operations and the market price of
its common stock.

    John G. Balletto filed a lawsuit against Xoom.com in September 1999 in the
San Francisco Superior Court alleging breach of contract and specific
performance. Mr. Balletto has alleged that in connection with a loan which
Xoom.com obtained from Sand Hill Capital LLC in 1998 and pursuant to an oral
contract with Xoom.com, he is entitled to a finder's fee. Mr. Balletto has
sought specific performance of the alleged oral contract by having the court
direct Xoom.com to issue 33,784 shares of its common stock to Mr. Balletto and
such other relief that the court may deem just and proper. Xoom.com believes
that this lawsuit is without merit and intends to defend the suit vigorously.

EMPLOYEES

    As of August 31, 1999, Xoom.com had 199 full-time employees, including 102
in sales and marketing, 62 in operating and development and 35 in finance and
administration. Xoom.com's future success will depend, in part, on its ability
to continue to attract, retain and motivate highly qualified technical and
management personnel, for whom competition is intense. From time to time,
Xoom.com also employs independent contractors to support its research and
development, marketing, sales and support and administrative organizations.
Xoom.com's employees are not covered by any collective bargaining agreement, and
Xoom.com has never experienced a work stoppage. Xoom.com believes its relations
with its employees are good.

FACILITIES

    Xoom.com's headquarters are currently located in a leased facility in San
Francisco, California, consisting of approximately 29,000 square feet of office
space, which is under leases that expire through September 30, 2007. Xoom.com
intends to move its headquarters in early 2000 to a leased facility in San
Francisco, California, consisting of approximately 187,000 square feet of office
space, which is under a lease that expires in approximately 2010. Xoom.com also
leases approximately 6,500 square feet of office space in New York, New York for
its East Coast sales offices under a lease that expires July 15, 2004. In
addition, Xoom.com's wholly-owned subsidiary Liquid Market leases approximately
4,000 square feet of office space in Los Angeles, California on a month-to-month
basis.

   XOOM.COM'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

    The following discussion should be read in conjunction with the financial
statements and related notes included elsewhere in this proxy
statement/prospectus. The results shown in this proxy statement/ prospectus do
not necessarily indicate the results to be expected in any future periods. This
discussion contains forward-looking statements based on current expectations
that involve risks and uncertainties. Actual results and the timing of events
may differ significantly from those projected in such forward looking statements
due to a number of factors, including those set forth in the section entitled
"Risk Factors" and elsewhere in this proxy statement/prospectus.

OVERVIEW

    Xoom.com was incorporated in April 1996 and commenced offering products for
sale on its Web site in March 1997. From inception through December 1996,
Xoom.com had no sales and its operating activities related primarily to
developing necessary computer infrastructure, recruiting personnel, raising
capital and initial planning and development of the Xoom.com site. For the
period beginning with the operation of the Xoom.com site through December 31,
1997, Xoom.com continued these activities and focused on building sales
momentum, establishing relationships with manufacturers, marketing the Xoom.com
brand and establishing customer service and fulfillment operations.

    Xoom.com generates net revenue from e-commerce, primarily through the use of
direct e-mail marketing, licensing and the sale of advertising on its Web site.
Total net revenue was $841,000, $8.3 million and $10.9 million for the years
ended December 31, 1997 and 1998 and for the six months ended June 30, 1999,
respectively. The increase in total net revenue was primarily due to the growth
of its member base, which resulted in increases in e-commerce revenue, increased
Web-based advertising revenue and, to a lesser extent, an increase in license
and other fees. Cost of net revenue increased substantially in absolute dollars,
reflecting the increased sales volume. As Xoom.com has grown, its operating
expenses in absolute dollars have increased. Xoom.com expects that the dollar
amount of its operating expenses will continue to increase as a result of
acquisitions, sales and marketing efforts, increased funding of site
development, branding of the Xoom.com name and the expansion of technology,
operating infrastructure and general and administrative staff needed to support
its growth.

    From inception through June 30, 1999, Xoom.com generated total net revenue
of approximately $20.1 million. Quarterly net revenue increased from
approximately $420,000 in the fourth quarter of 1997 to $6.5 million in the
second quarter of 1999. Since January 1998, the number of members has grown from
100,000 to 9.2 million as of July 31, 1999.

    As of June 30, 1999, Xoom.com had an accumulated deficit of $24.8 million.
Although Xoom.com has experienced growth in net revenue, members, customers and
reach in recent periods, these growth rates are not sustainable. These growth
rates will decrease and are not indicative of future growth rates that Xoom.com
may experience.

    Xoom.com has not achieved profitability on a quarterly or annual basis to
date, and anticipates that it will incur net losses for the foreseeable future.
The extent of these losses will depend, in part, on the amount and rates of
growth in its net revenue from e-commerce and advertising. Xoom.com expects its
operating expenses to increase significantly, especially in the areas of sales
and marketing and brand promotion. As a result, Xoom.com will need to increase
its quarterly net revenue to achieve profitability. Xoom.com believes that
period-to-period comparisons of its operating results are not meaningful and
that you should not rely upon the results for any period as an indication of
future performance. Xoom.com's business, results of operations and financial
condition will be materially and adversely affected if:

    - net revenue does not grow at anticipated rates;

    - increases in operating expenses are not offset by commensurate increases
      in net revenue; or

                                      149
<PAGE>
    - Xoom.com is unable to adjust operating expense levels in light of net
      revenue.

    Xoom.com's operating losses might increase in the future, and Xoom.com
cannot guarantee that it will ever achieve or sustain profitability.

    To date, Xoom.com has entered into various business and technology
acquisitions, license arrangements and strategic alliances in order to build its
communities, provide community-specific content, generate additional traffic,
increase the number of members and establish additional sources of net revenue.
In March 1998, Xoom.com acquired Paralogic Corporation, a chat service, for a
purchase price of approximately $3.0 million. Xoom.com also acquired Sitemail,
an HTML-based e-mail product, through its purchases of Global Bridges and
selected assets of Revolutionary Software in June 1998. HTML refers to hypertext
markup language, a computer language that people use widely to create Web sites.
Global Bridges, which Xoom.com purchased for approximately $1.2 million, owned
the exclusive selling rights to Sitemail. Revolutionary Software, from which
Xoom.com purchased selected assets for approximately $1.7 million, developed
Sitemail and had licensed it to Global Bridges. Also in June 1998, Xoom.com
purchased from ArcaMax an exclusive, perpetual license to use Greetings Online,
an online greeting card service, for approximately $644,000. Additionally, in
July 1998, Xoom.com acquired Pagecount, a Web page counter and guestbook
service, for approximately $1.5 million. In April 1999, Xoom.com acquired
Focused Presence, Inc., a company that operates a global directory of small
businesses, for approximately $1.7 million. In May 1999, Xoom.com acquired
Netfloppy.com LLC, a provider of online file storage for Web users for
approximately $1.4 million, and MightyMail Networks, Inc., a developer of an
enhanced e-mail product that enables customization of e-mail according to user
preferences for approximately $23.1 million. In June 1999, Xoom.com acquired
Paralogic Software Corporation, which provides Web site authoring and community
building tools, such as Java based community products and services, including
customizable chat rooms, discussion boards, guestbooks and event calendars, for
approximately $35.4 million.

    Because most Internet business acquisitions involve the purchase of
significant amounts of intangible assets, acquisitions of such businesses also
result in goodwill and purchased technology and significant charges for
purchased in-process research and development. During 1998, Xoom.com expensed
$790,000 for purchased in-process research and development and approximately
$1.8 million for the amortization of goodwill and purchased technology. During
the six months ended June 30, 1998 and 1999, Xoom.com expensed $660,000 and $2.6
million, respectively for purchased in-process research and development and
approximately $346,000 and $2.3 million, respectively for the amortization of
goodwill and purchased technology.

    Xoom.com intends to continue making acquisitions to increase online reach
and membership and to seek additional strategic alliances with content and
distribution partners, including alliances that create co-branded sites through
which Xoom.com markets its services. Acquisitions carry numerous risks and
uncertainties, including:

    - difficulties in integrating operations, personnel, technologies, products
      and the information systems of the acquired companies;

    - diversion of management's attention from other business concerns;

    - risks of entering geographic and business markets in which Xoom.com has
      little or no prior experience; and

    - potential loss of key employees of acquired entities.

    Xoom.com cannot guarantee that it will be able to successfully integrate any
businesses, products, technologies or personnel that might be acquired in the
future. A failure to integrate acquired entities or assets successfully could
have a material adverse effect on its business, results of operations and
financial condition. In addition, Xoom.com cannot guarantee that it will be
successful in identifying and closing transactions with potential acquisition
candidates.

    International sales comprised approximately 30%, 25% and 16% of total net
revenue for the years ended December 31, 1997 and 1998 and the six months ended
June 30, 1999, respectively. This consisted of $252,000, $2.1 million and $1.7
million in net revenue, respectively, during such periods.

    Xoom.com has recorded deferred stock compensation charges of $0, $551,000
and $2.0 million during the period from April 16, 1996, its inception, through
December 31, 1996 and for the years ended December 31, 1997 and 1998,
respectively. These charges account for the difference between the exercise
price and the value of some of the stock options Xoom.com granted to its
employees. The deferred compensation charges include options granted to various
employees that vest upon specified events, such as the successful completion of
an initial public offering or the achievement of individual performance goals.
In June 1998, Xoom.com modified these options so that they fully vest upon the
earlier of such an event or two years from the date of grant. Therefore,
Xoom.com recorded related deferred compensation charges of approximately
$783,000 and amortization charges, based on cumulative vesting to that date, of
approximately $618,000 in June 1998. Xoom.com recorded amortization of deferred
stock compensation of $248,000, $1.4 million and $405,000 in the years ended
December 31, 1997 and 1998 and the six months ended June 30, 1999, respectively.
Xoom.com expects to record amortization expense related to these deferred stock
compensation charges of approximately $580,000, $225,000, $80,000 and $20,000 in
the years ended December 31, 1999, 2000, 2001 and 2002, respectively. Xoom.com
cannot guarantee, however, that it will not accrue additional charges for other
reasons or that its current estimates of these charges will prove accurate,
either of which events could have a material adverse effect on its business,
results of operations and financial condition.

    Xoom.com will need to increase its inventory levels in the future to support
a wider base of e-commerce products and to take advantage of volume purchase
discounts. Xoom.com contracts with a third party warehousing and order
fulfillment company to stock inventory and ship products directly to customers.
Xoom.com takes title to this inventory, has responsibility for this inventory,
and records inventory on its balance sheet until the final shipment to customers
or other disposition of the inventory. There are inherent risks and costs in
stocking inventory and coordinating with a third party warehousing and order
fulfillment company. These risks include, but are not limited to, product
obsolescence, excess inventory and inventory shortages resulting in unfulfilled
orders, which could materially adversely affect operating results in the future.

RECENT EVENTS

    On August 3, 1999, Xoom.com acquired 100% of the outstanding shares of

- ------------------------

(1) There were no material costs of advertising revenue during the years ended
    December 31, 1997 and 1998.

    NET REVENUE

    Xoom.com began generating net revenue in the first quarter of 1997.
Xoom.com's total net revenue increased to $8.3 million in the year ended
December 31, 1998 from $841,000 in the year ended December 31, 1997. Net revenue
is composed of e-commerce product sales, which includes outbound shipping and
handling fees, advertising revenue, license fees and other revenue. The increase
in net revenue was primarily due to the following four factors:

    - the expansion of its membership base;

    - an increase in the frequency of e-mail offerings and broader product
      offerings, which resulted in an increase in product sales through
      e-commerce;

                                      152
<PAGE>
    - an increase in Web-based advertising, Xoom.com's higher Web site traffic
      increased its attractiveness to advertisers; and

    - to a lesser extent, an increase in license fees.

    No customer accounted for more than 10% of total net revenue for the year
ended December 31, 1998, and one licensing customer accounted for 12% of total
net revenue for the year ended December 31, 1997.

    E-COMMERCE REVENUE

    E-commerce revenue increased to $5.6 million in the year ended December 31,
1998 from $327,000 in the year ended December 31, 1997. The increase in net
revenue was primarily due to the expansion of its membership base, which
resulted in an increase in product sales, as well as expansion of the breadth of
products offered. The percentage of its total net revenue attributable to
e-commerce revenue increased to 67.1% in the year ended December 31, 1998 from
38.9% in the year ended December 31, 1997. Xoom.com expects e-commerce revenue
to continue to account for a large percentage of net revenue as Xoom.com expands
its product offerings and increases its direct e-commerce response rates through
better member demographic information and targeting of product offers.

    Xoom.com believes that offering its customers attractive prices is an
essential component of its business strategy. Xoom.com may in the future
increase the discounts Xoom.com offers its customers and may otherwise alter its
pricing structures and policies. Xoom.com anticipates that any increase in
discounts or price reductions will reduce gross margins below those Xoom.com
experienced for the years ended December 31, 1998 and 1997.

    ADVERTISING REVENUE

    Advertising revenue increased to $2.1 million in the year ended December 31,
1998 from $60,000 in the year ended December 31, 1997. The increase in
advertising revenue is primarily a result of the increase in Xoom.com's
membership, site traffic and expansion of its advertising sales force. The
percentage of Xoom.com's total net revenue attributable to advertising revenue
increased to 25.8% in the year ended December 31, 1998 from 7.1% in the year
ended December 31, 1997.

    LICENSE FEES AND OTHER REVENUE

    License fees and other revenue increased to $592,000 in the year ended
December 31, 1998 from $454,000 in the year ended December 31, 1997. The
increase in license fees and other revenue is primarily a result of additional
clip art and other utilities Xoom.com was able to license to third parties. The
percentage of its total net revenue attributable to license fees decreased to
7.1% in the year ended December 31, 1998 from 54% in the year ended December 31,
1997. As Xoom.com expands its e-commerce and advertising revenue, license fees
and other revenue will continue to represent a smaller percentage of net
revenue.

    COST OF NET REVENUE

    Gross margins decreased to 56.9% in the year ended December 31, 1998 from
62.1% in the year ended December 31, 1997, as a result of the increase in
e-commerce revenue as a percentage of total net revenue. As a percentage of
total net revenue, the cost of e-commerce increased to 42.6% of net revenue in
the year ended December 31, 1998 from 20.3% of net revenue in the year ended
December 31, 1997. There were no material costs of net revenue associated with
advertising.

                                      153
<PAGE>
    COST OF E-COMMERCE REVENUE

    Cost of e-commerce consists primarily of the costs of merchandise sold to
customers, credit card commissions, product fulfillment, and outbound shipping
and handling costs. Cost of e-commerce was $3.5 million and $171,000 for the
years ended December 31, 1998 and 1997, respectively. As a percentage of
e-commerce revenue, the cost of e-commerce was 63.4% and 52.3% for the years
ended December 31, 1998 and 1997, respectively. The increase was primarily
attributable to the fact that in 1998 Xoom.com broadened its product offerings.
Xoom.com's new product offerings included items with higher costs than in the
prior year.

    COST OF LICENSE FEES AND OTHER REVENUE

    Cost of license fees and other consists primarily of royalties on net
revenue from license fees. Cost of license fees was $42,000 and $148,000 for the
years ended December 31, 1998 and 1997, respectively. As a percentage of license
fees and other, cost of license fees and other were 7.2% and 32.7% for the years
ended December 31, 1998 and 1997, respectively. Cost of license fees and other
for the year ended December 31, 1997 included $81,000 in amortization of prepaid
royalties related to a product that Xoom.com discontinued in the fourth quarter
of 1997.

    The mix of products Xoom.com sells will impact its gross margins and the
overall mix of e-commerce revenue, advertising revenue and license and other
fees. Xoom.com typically recognizes higher gross margins on advertising revenue
and license and other fees, which are expected to comprise a lower percentage of
total net revenue in the future. Therefore, Xoom.com expects shifts in the mix
of sales will adversely impact its overall gross margin and could materially
adversely impact its business, results of operations and financial condition.

    OPERATING AND DEVELOPMENT EXPENSES

    Operating and development expenses consist primarily of payroll and related
expenses for development and network operations personnel and consultants, costs
related to systems infrastructure including Web site hosting, and costs of
acquired content to enhance its Web site. Operating and development expenses
increased to $3.8 million in the year ended December 31, 1998 from $1.2 million
in the year ended December 31, 1997, and $266,000 in the period from April 16,
1996 through December 31, 1996. From inception to the year ended December 31,
1997, apart from its Web site, Xoom.com incurred approximately $300,000 in costs
relating to the development of a home office software product, which was
subsequently abandoned due to low sales volume. From June 30, 1997 to December
31, 1998, the absolute dollar increases from quarter to quarter in operating and
development expenses were primarily attributable to increases in the number of
personnel and associated costs related to enhancing the functionality and
content of its Web site. Operating and development costs decreased as a
percentage of total net revenue to 46.2% in the year ended December 31, 1998
from 136.8% in the year ended December 31, 1997.

    Xoom.com believes operating and development expenses will increase
significantly in the future, especially in relation to Web site hosting costs,
as its membership grows, thus requiring additional bandwidth to support the many
free services offered to members. Xoom.com believes that it will need to make
significant investments in its Web site to remain competitive. Therefore,
Xoom.com expects that its operating and development expenses will continue to
increase in absolute dollars for the foreseeable future.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses consist primarily of payroll and related
expenses for personnel engaged in sales, marketing, publishing and customer
support, as well as advertising and promotional expenditures. Sales and
marketing expenses increased to $2.8 million in the year ended December 31,

                                      154
<PAGE>
1998 from $292,000 in the year ended December 31, 1997, and $24,000 in the
period from April 16, 1996 to December 31, 1996. The absolute dollar increases
from period to period in sales and marketing expenses were primarily
attributable to increased personnel and related expenses required to implement
its sales and marketing strategy as well as increased public relations and other
promotional expenses. Sales and marketing costs decreased as a percentage of
total net revenue to 34.1% in the year ended December 31, 1998 from 34.7% in the
year ended December 31, 1997. Xoom.com expects to continue hiring additional
personnel and to pursue a branding and marketing campaign. Therefore, Xoom.com
expects marketing and sales expenses to increase significantly in absolute
dollars.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses consist primarily of payroll and related
costs for general corporate functions, including finance, accounting, business
development, human resources, investor relations, facilities and administration,
as well as legal fees, and fees for professional services and directors. General
and administrative expenses increased to $3.4 million in the year ended December
31, 1998 from $721,000 in the year ended December 31, 1997, and $150,000 from
April 16, 1996 to December 31, 1996. The absolute dollar increases from period
to period in general and administrative expenses were primarily due to increases
in the number of general and administrative personnel, professional services,
directors fees and facility expenses to support the growth of its operations.
General and administrative expenses decreased as a percentage of total net
revenue to 40.5% in the year ended December 31, 1998 from 85.7% in the year
ended December 31, 1997. General and administrative expenses as a percentage of
net revenue have decreased because of the growth in net revenue. Xoom.com
expects general and administrative expenses to increase in absolute dollars in
future periods as Xoom.com expands its staff, incurs additional costs related to
its operations, and is subject to the requirements of being a publicly traded
company.

    PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT

    For the year ended December 31, 1998, Xoom.com recognized charges to
operations for purchased in-process research and development of $330,000 in
connection with the acquisition of Paralogic Corporation, $330,000 in connection
with the purchase of selected assets of Revolutionary Software and $130,000 in
connection with the acquisition of Pagecount. Xoom.com did not recognize such
charges for the year ended December 31, 1997 or for the period from April 16,
1996 through December 31, 1996.

    In connection with the Paralogic Corporation acquisition, Xoom.com acquired
Paralogic Corporation's base of chat members, called the ParaChat Personal
Network, as well as the rights to use the underlying chat technology, called
ParaChat Personal. ParaChat Personal is designed to provide Web sites with an
option to offer chat technology without requiring Web site hosts to buy the
software, maintain or upgrade the software, or learn any additional skills
beyond what is necessary to construct a Web site. The chat software is
maintained on Xoom.com's server and the Web site host is provided bits of source
code or "tags" that are incorporated into the Web site. The tags interface via
the Internet with the ParaChat server, and thus provide the Web site with chat
capabilities. In exchange for the free service, the Web site host allows banner
advertising on its site.

    As of the time of acquisition, ParaChat Personal was not completely
functional as a commercially viable product. The nature, amount and timing of
the remaining estimated efforts necessary to develop the acquired, incomplete
ParaChat Personal technology into a commercially viable product included:

    - REMOTE DATABASE AUTHENTICATION:  The chat server used a very simple
      flat-file database to maintain authentication information. In order to
      allow users to control their own password and user information, it was
      necessary to design a protocol using the Java programming language. This
      language enabled the chat server to remotely query an external Oracle
      database through

                                      155
<PAGE>
      the Internet to retrieve and modify information relating to the user and
      the chat room, e.g., the topic of discussion.

    - CREATION OF NEW CHAT CLIENT:  The chat software is comprised of two parts:
      the client and the server. Although the server claimed compatibility with
      Internet Standard RFC1459, this feature was not useable on a commercial
      basis. Internet Standard RFC1459 is a standard message format for Internet
      relay chat, allowing usage on multiple platforms. The server functioned
      only with the limited ParaChat Personal client, which did not allow for
      configuration or reconfiguration by the end-user to match the look and
      feel of an existing Web site. In order to allow deployment on an existing
      site, it was necessary to create an entirely new client that consisted of
      various building blocks that could be composed by the end-user using HTML.
      These building blocks would then use a Java-based communication protocol
      to communicate with each other and coordinate communication with the chat
      server. Since the Java-based communication protocol is not well defined,
      and differs between browser implementations, a substantial amount of
      additional software development was required, particularly because no
      comparable client exists in the market today.

    - CONTROL INTERFACE:  The acquired ParaChat Personal network did not allow
      users to control or administer their chat room in any way, e.g., eject
      abusive users, close the chat room or even specify a discussion topic. The
      enhancements necessary to make these features available, and to allow them
      to be maintained and administered via the central authentication database
      were complex and required significant additional development.

    - ADVANCES IN BROWSER TECHNOLOGY:  In addition to the above modifications
      and other maintenance modifications and bug fixes, the rapid advances in
      Web browser technology implied continuous implementation of new features
      to exploit new browser technologies.

    As of the date of the technology's valuation, Xoom.com estimated that 55% of
the research and development effort had been completed at the date of
acquisition and expected the remaining research and development efforts relating
to the completion of the ParaChat Personal technology would require
approximately six months of effort from the date of valuation through its
release date of September 1, 1998. Xoom.com estimated that three full-time
engineers would be required to complete the in-process projects. These projects
included the use of one full-time engineer for six months to work on the
external database connectivity efforts, one full-time engineer for six months to
work on the client layout efforts, and one full-time engineer for six months to
work on the management and control interface efforts. Accordingly, it was
determined that total estimated research and development costs-to-complete for
the ParaChat Personal in-process project were $112,500. Xoom.com completed the
project by the scheduled date and the actual costs of completion were not
materially different than estimated.

    As of the date of valuation, Xoom.com expected the benefit of the acquired
project to begin immediately after the estimated completion date. Xoom.com
expected that the in-process project would be developed to technological
feasibility concurrent with the September 1998 release date. Xoom.com has
demonstrated the ability to implement the on-going research and development on
time and on budget.

    The technology that Xoom.com acquired from Revolutionary Software was a
Web-based e-mail technology known as SiteMail. This in-process Web-based e-mail
technology was designed to allow users to receive and send e-mail through the
Internet using a Web browser. Since the technology was Web-based, it would allow
for the integration of e-mail functionality into Web sites and would be
accessible by any Web-connected device anywhere in the world. Furthermore, by
integrating e-mail into a specific site, it would force the subscriber to visit
that site to access e-mail, thereby increasing traffic. In addition, when users
apply for e-mail accounts at Web sites offering SiteMail, they are given the
domain name of that Web site or company. The personalization of the domain name
in an e-mail address has become an innovative way of promoting a company's name
or Web site.

    As of the date of acquisition, SiteMail was in the alpha testing stage of
development and required the resolution of scalability technological hurdles in
order to complete the technology. In addition to the scalability issues, the
following functionality requirements also needed to be addressed by on-going
research and development efforts:

    - improving the user interface;

    - connecting the e-mail server with external databases;

    - completing spam detection and filtering functions; and

    - completing security enhancements for Unix Internet applications.

    As of the date of acquisition, Xoom.com estimated that approximately 50% of
the research and development effort had been completed and expected the
remaining research and development efforts relating to the completion of the
SiteMail technology to continue from the date of acquisition through the release
date of November 1998. The remaining development effort was estimated to require
approximately 4.5 months of engineering effort. Xoom.com estimated that 3.5
full-time developers would be required to complete this project. The total cost
of remaining development was estimated to be approximately $98,000. Xoom.com
completed the project by the scheduled date and the actual costs of completion
were not materially different than estimated.

    In connection with the Pagecount acquisition, Xoom.com acquired a Web page
counter product, titled Pagecount. This product is a banner page counter that
tracks the number of visitors that view a member's site. It further breaks down
impression statistics, or page views by day, date and time. Other statistics
include a list of locations from where the requests originated and the host
names of up to 100 visitors. The software is maintained on the Pagecount server
and tags are integrated into the Web site which interface with the Pagecount
server. In exchange for the use of the Pagecount service, a banner advertisement
may be placed on each counter image.

    Specifically, the nature, amount and timing of the remaining estimated
efforts necessary to develop the acquired incomplete Pagecount technology into a
commercially viable product included:

    - STAGE OF DEVELOPMENT:  As of the date of the transactions, Pagecount was
      not yet able to handle large usage volumes and was only able to maintain
      statistical information for small members experiencing low levels of
      traffic. In addition, Pagecount did not have an advertising delivery
      capability and, historically, advertisements had to be superimposed onto
      the Web site by a human operator. This is a very inefficient method of
      placing advertisements onto Web sites and as volume increases it would be
      impossible to maintain the advertising inventory. At the date of
      valuation, Pagecount was developing an advertising delivery system that
      would maximize the advertising inventory being generated. Furthermore,
      additional development was required to integrate the Pagecount technology
      into its infrastructure in order for it to be compatible with its network.

    - ADDITIONAL RESEARCH AND DEVELOPMENT REQUIRED:  Ultimately the most
      significant research and development efforts related to the remaining
      engineering of the Pagecount server to permit

       (A) advertisers in the network access to industry-standard reports;

       (B) advertisements to be placed into the network using industry standard
           delivery software; and

       (C) users to attain enhanced reporting and credit for having displayed a
           large number of banners, perhaps as a banner exchange offering.

    Xoom.com estimated that approximately 55% of the research and development
effort had been completed at the date of acquisition and expected the remaining
research and development efforts

                                      157
<PAGE>
relating to the completion of the Pagecount technology to continue from the date
of acquisition through the release date of mid-December 1998. The remaining
development effort at the date of acquisition was estimated to require
approximately five months of engineering effort. Xoom.com estimated that 2.5
full-time developers would be required to complete this project. The total
estimated remaining development effort equates to a total cost to complete of
approximately $78,000. Xoom.com completed the project by the scheduled date and
the actual costs of completion were not materially different than estimated.

    AMORTIZATION OF DEFERRED COMPENSATION

    Deferred compensation expense reflects the amortization of stock
compensation charges resulting from stock options and restricted stock purchase
agreements. Stock compensation charges increased to $1.4 million for the year
ended December 31, 1998 from $248,000 for the year ended December 31, 1997. This
increase was primarily attributable to the modification of some options, which
required Xoom.com to accelerate the amortization of the related deferred
compensation, which occurred during the quarter ended June 30, 1998, as well as
an increase in the number of options Xoom.com granted to employees and
consultants.

    AMORTIZATION OF INTANGIBLE ASSETS

    Amortization of intangible assets totaled $1.8 million for the year ended
December 31, 1998. This amount represents amortization of intangible assets and
goodwill resulting from its acquisitions of Paralogic, Global Bridges and
Pagecount and the purchase of selected assets of Revolutionary Software,
amortized over periods ranging from 24 to 42 months.

    Xoom.com has determined that, in relation to the intangible assets and based
on general and specific analysis, 2 to 3.5 year estimated useful lives are
appropriate. In general, the Internet is characterized by rapid technological
change, changes in users and customer requirements and preferences, frequent new
product and service introductions and the emergence of new industry standards
and practices.

    The market for community-based direct selling channels on the Internet is
new and rapidly evolving and competition for members, consumers, visitors and
advertisers is intense. In addition, Xoom.com attracts members to its Web site
with a variety of free services, including home pages, e-mail, chat rooms,
electronic newsletters, clip art and software libraries, online greeting cards
and page counters. In order to continue attracting members using these various
methods, the free services must be constantly updated and improved.

    With respect to the purchased technology associated with all business and
technology acquisitions, Xoom.com considered the effects of obsolescence,
demand, competition, and other economic factors. Due to the rapid technological
change involved in the Internet, Xoom.com estimated that new technologies would
replace the intangible assets relating to the purchased technology within a 2 to
3.5 year period.

    With respect to the goodwill associated with all of the acquisitions,
Xoom.com considered the effects of obsolescence, demand, competition, other
economic factors and expected actions of competitors and others. Based on these
considerations, Xoom.com determined the positive effect of the acquisitions, and
therefore the life of the goodwill, to be from 24 to 42 months.

    With respect to the intangible assets associated with Global Bridges,
Pagecount, Revolutionary Software, and ArcaMax, Xoom.com considered the
competition for users of electronic mail, Web page counters, and online greeting
card services. Xoom.com also considered the fact that they provide free e-mail
and online greeting card services to all members. Xoom.com expects to generate
revenue from advertising and direct e-commerce to such users. The competition
for these users is intense and

                                      158
<PAGE>
Xoom.com expects that within two years Xoom.com or its competitors will develop
new technologies that will render the existing products obsolete. The
obsolescence of its existing technologies, without the introduction of new
products, could result in a loss of members. As a result, Xoom.com determined
the positive effect of the Global Bridges, Pagecount, Revolutionary Software and
ArcaMax transactions, and therefore the life of intangible assets, to be from 24
to 42 months.

    NON-RECURRING CHARGES

    Non-recurring charges totaled approximately $1.2 million in the year ended
December 31, 1997. These charges consisted of a $243,000 write-off of costs
associated with a discontinued product, and a $1.0 million provision for a legal
dispute for a copyright infringement claim from Imageline relating to some of
the clip art images that Xoom.com had licensed from an unrelated third party.
This litigation might subject Xoom.com to significant liability for damages
which could have a material adverse impact on its business, results of
operations, cash flows and financial condition. This might result in
invalidation of its proprietary rights. Even if the suit is without merit, it
could be time consuming and expensive to defend, and this could result in the
diversion of management time and attention, any of which might have a material
adverse impact on its business, results of operations, cash flows and financial
condition.

    INCOME TAXES

    There was no provision for federal or state income taxes for any period as
Xoom.com has incurred operating losses. As of December 31, 1998, Xoom.com had
net operating loss carryforwards for federal income tax purposes of
approximately $4.9 million. Xoom.com cannot assure you that it will realize the
benefit of the net operating loss carryforwards. The federal net operating loss
carryforwards will expire at various dates beginning in fiscal year 2011 through
2018 if Xoom.com does not use them. Due to the "change of ownership" provisions
of the Internal Revenue Code, the availability of Xoom.com's net operating loss
and credit carryforwards will be subject to an annual limitation against taxable
income in future periods if the transactions are consummated.

    NET LOSS

    Xoom.com's net loss for the year ended December 31, 1998 was $10.8 million
and it was $3.1 million for the year ended December 31, 1997. The increase in
the net loss was a result of an increase in operating expenses which were $14.1
million in the year ended December 31, 1998, compared to $3.7 million in the
year ended December 31, 1997. The operating expenses in the year ended December
31, 1998 included amortization of goodwill and other intangible assets of $1.8
million related to acquisitions, and amortization of deferred compensation of
$1.4 million. The operating expenses in the year ended December 31, 1997 also
included amortization of deferred compensation of $248,000 and non-recurring
charges of $1.2 million. The expenses in the year ended December 31, 1998 were
partially offset by revenues of $8.3 million. The expenses in the year ended
December 31, 1997 were partially offset by revenues of $841,000.

(1) There were no material costs of advertising revenue during 1998.

    NET REVENUE

    Total net revenue for the three months ended June 30, 1999 was $6.5 million,
an increase of approximately $4.8 million over revenues of $1.7 million for the
three months ended June 30, 1998. Total net revenue for the six months ended
June 30, 1999 was $10.9 million, an increase of approximately $8.3 million over
revenues of $2.6 for the six months ended June 30, 1998. The increases in both
the three-month and six-month periods were primarily due to the following three
factors:

    - the expansion of Xoom.com's membership base;

    - an increase in the frequency of e-mail offerings and broader product
      offerings, which resulted in an increase in product sales through
      e-commerce; and

    - an increase in Web-based advertising--Xoom.com's higher Web site traffic
      increased its attractiveness to advertisers.

                                      160
<PAGE>
    E-COMMERCE REVENUE

    E-commerce revenue increased to $3.3 million in the three months ended June
30, 1999 from $1.2 million in the three months ended June 30, 1998. E-commerce
revenue increased to $5.9 million in the six months ended June 30, 1999 from
$1.8 million in the six months ended June 30, 1998. The increases in net revenue
in both periods are primarily due to the expansion of Xoom.com's membership
base, which resulted in an increase in product sales, as well as expansion of
the breadth of products offered. The percentage of Xoom.com's total net revenue
attributable to e-commerce revenue decreased to 50.5% in the three months ended
June 30, 1999 from 67.4% in the three months ended June 30, 1998. The percentage
of Xoom.com's total net revenue attributable to e-commerce revenue decreased to
54.2% in the six months ended June 30, 1999 from 71.5% in the six months ended
June 30, 1998. The decreases in both periods were due to the fact that
advertising revenue grew at a more rapid rate than e-commerce revenue during the
three and six months ended June 30, 1999 as compared to the three and six months
ended June 30, 1998. Xoom.com expects e-commerce revenue to continue to account
for a large percentage of net revenue as it expands its product offerings and
increases its direct e-commerce response rates through better member demographic
information and targeting of product offers.

    Xoom.com believes that offering its customers attractive prices is an
essential component of its business strategy. Xoom.com may in the future
increase the discounts offered to its customers and may otherwise alter its
pricing structures and policies. Xoom.com anticipates that any increase in
discounts or price reductions will reduce gross margins below those it
experienced for the three and six months ended June 30, 1999 and 1998.

    ADVERTISING REVENUE

    Advertising revenue increased to $3.2 million in the three months ended June
30, 1999 from $272,000 in the three months ended June 30, 1998. Advertising
revenue increased to $5.0 million in the six months ended June 30, 1999 from
$355,000 in the six months ended June 30, 1998. The percentage of Xoom.com's
total net revenue attributable to advertising revenue increased to 49.2% in the
three months ended June 30, 1999 from 15.9% in the three months ended June 30,
1998. The percentage of Xoom.com's total net revenue attributable to advertising
revenue increased to 45.4% in the six months ended June 30, 1999 from 13.8% in
the six months ended June 30, 1998. The increases in advertising revenue in each
period in both absolute dollars and in percentage of net revenue are primarily a
result of the increase in Xoom.com's membership, increased site traffic, and
expansion of its advertising sales force. As Xoom.com's membership base
continues to grow and the demand for advertising on its Web-site remains strong,
Xoom.com can expect that its advertising revenues will continue to represent a
large percentage of its overall net revenue.

    LICENSE FEES AND OTHER REVENUE

    Licensing revenue decreased to $18,000 in the three months ended June 30,
1999 from $287,000 in the three months ended June 30, 1998. Licensing revenue
decreased to $39,000 in the six months ended June 30, 1999 from $376,000 in the
three months ended June 30, 1998. As Xoom.com expands its e-commerce and
advertising revenue, it can expect that licensing revenue will continue to
represent a small percentage of net revenue.

    COST OF NET REVENUE

    Gross margins decreased to 58.9% in the three months ended June 30, 1999
from 62.7% in the three months ended June 30, 1998. Gross margins decreased to
56.8% in the six months ended June 30, 1999 from 63.9% in the six months ended
June 30, 1998. Both decreases were a result of a change in the overall product
mix. In the three and six months ended June 30, 1999, Xoom.com began

                                      161
<PAGE>
selling a broader range of products than in the three and six months ended June
30, 1998. The new product mix includes higher priced items, such as digital
versatile disks and digital cameras, that have lower gross margin percentages.

    COST OF E-COMMERCE REVENUE

    Cost of e-commerce revenue consists primarily of the costs of merchandise
sold to customers, credit card commissions, product fulfillment, and outbound
shipping and handling costs. Cost of e-commerce was $2.6 million for the three
months ended June 30, 1999 and it was $621,000 for the same period ended June
30, 1998. Cost of e-commerce revenue was $4.6 million for the six months ended
June 30, 1999 and it was $899,000 for the same period ended June 30, 1998. As a
percentage of e-commerce revenue, the cost of e-commerce was 79.1% for the three
months ended June 30, 1999 and it was 53.7% for the same period ended June 30,
1998. As a percentage of e-commerce revenue, the cost of e-commerce was 78.4%
for the six months ended June 30, 1999 and it was 49.0% for the same period
ended June 30, 1998. The increase was primarily attributable to the fact that in
1999 Xoom.com broadened its product offerings. Xoom.com's new product offerings
included items with higher costs than in the prior year.

    COST OF ADVERTISING REVENUE

    Cost of advertising revenue consists primarily of revenue share amounts
Xoom.com pays its customers for advertising sold on co-branded sites. Cost of
advertising revenue was $75,000 in the three and six months ended June 30, 1999
and it was $0 in the same periods ended June 30, 1998. This increase is
primarily a result of an increased demand for advertising on co-branded sites,
and the expansion of Xoom.com's advertising and business development sales
forces.

    COST OF LICENSING REVENUE

    Cost of licensing revenue consists primarily of royalties on net revenue
from license fees. Cost of licensing revenue was $0 for the three months ended
June 30, 1999 and it was $19,000 for the same period ended June 30, 1998. The
costs of licensing revenue were $0 during the six months ended June 30, 1999 and
$27,000 during the same period ended June 30, 1998. Xoom.com expects that the
cost of licensing revenue should continue to be a small percentage of total cost
of revenues.

    The mix of products Xoom.com sells will impact its gross margins and the
overall mix of e-commerce revenue, advertising revenue and licensing revenue.
Xoom.com typically recognizes higher gross margins on advertising revenue and
licensing revenue. Xoom.com expects that shifts in the mix of sales could
adversely impact its overall gross margin and could materially adversely impact
its business, results of operations and financial condition.

    OPERATING AND DEVELOPMENT EXPENSES

    Operating and development expenses consist primarily of payroll and related
expenses for development and network operations personnel and consultants, costs
related to systems infrastructure including Web site hosting, and costs of
acquired content to enhance the Xoom.com Web site. Operating and development
expenses increased to $1.6 million in the three months ended June 30, 1999 from
$773,000 in the three months ended June 30, 1998. Operating and development
expenses increased to $2.7 million in the six months ended June 30, 1999 from
$1.3 million in the six months ended June 30, 1998. Xoom.com believes operating
and development expenses will increase significantly in the future, especially
in relation to Web site hosting costs, as its membership grows, thus requiring
additional bandwidth to support the many free services offered to members.
Xoom.com believes that it will need to make significant investments in its Web
site to remain competitive. Therefore, Xoom.com

                                      162
<PAGE>
expects that its operating and development expenses will continue to increase in
absolute dollars for the foreseeable future.

    Operating and development costs decreased as a percentage of total net
revenue to 23.8% in the three months ended June 30, 1999 from 45.0% in the three
months ended June 30, 1998. Operating and development costs decreased as a
percentage of total net revenue to 24.7% in the six months ended June 30, 1999
from 52.6% in the six months ended June 30, 1998. The decreases in operating and
development expense as a percentage of total revenue in both periods was due to
the overall growth in net revenue.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses consist primarily of payroll and related
expenses for personnel engaged in sales, marketing, publishing and customer
support, as well as advertising and promotional expenditures. Sales and
marketing expenses increased to $5.1 million in the three months ended June 30,
1999 from $455,000 in the three months ended June 30, 1998. Sales and marketing
expenses increased to $7.5 million in the six months ended June 30, 1999 from
$717,000 in the six months ended June 30, 1998. The absolute dollar increases
from period to period in sales and marketing expenses were primarily
attributable to increased personnel and related expenses required to implement
Xoom.com's sales and marketing strategy as well as increased public relations
and other promotional and advertising expenses. Additionally, in connection with
the proposed business combination of Xoom.com, SNAP and the NBC contributed
Internet assets, Xoom.com incurred a $424,000 charge related to the cancellation
of an advertising contract in the three and six months ended June 30, 1999.
Xoom.com expects to continue hiring additional personnel and to pursue a
branding and marketing campaign. Therefore, Xoom.com expects marketing and sales
expenses to continue to increase significantly in absolute dollars.

    Sales and marketing expenses increased as a percentage of total net revenue
to 78.2% in the three months ended June 30, 1999 from 26.5% in the three months
ended June 30, 1998. Sales and marketing expenses increased as a percentage of
total net revenue to 68.8% in the six months ended June 30, 1999 from 28.0% in
the six months ended June 30, 1998. The increase in sales and marketing expenses
as a percentage of total revenue in both periods is due to the hiring of new
sales and marketing personnel and other promotional and advertising expenses.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses consist primarily of payroll and related
expenses for general corporate functions, including finance, accounting,
business development, human resources, investor relations, facilities and
administration, as well as legal fees, insurance, and fees for professional
services and directors. General and administrative expenses increased to $2.0
million in the three months ended June 30, 1999 from $785,000 in the three
months ended June 30, 1998. General and administrative expenses increased to
$3.7 million in the six months ended June 30, 1999 from $1.1 million in the six
months ended June 30, 1998. The absolute dollar increases from period to period
in general and administrative expenses were primarily due to increases in the
number of general and administrative personnel, professional services,
directors' fees and facility expenses to support the growth of Xoom.com's
operations. Xoom.com expects general and administrative expenses to increase in
absolute dollars in future periods as it expands its staff and incurs additional
costs related to its operations.

    General and administrative expenses decreased as a percentage of total net
revenue to 31.3% in the three months ended June 30, 1999 from 45.8% in the three
months ended June 30, 1998. General and administrative expenses decreased as a
percentage of total net revenue to 33.5% in the six months ended June 30, 1999
from 42.8% in the six months ended June 30, 1998. The decreases in operating

                                      163
<PAGE>
and development expenses as a percentage of total revenue in both periods were
due to the overall growth in net revenue.

    PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT

    For the three months ended June 30, 1999 Xoom.com recognized the cost of
purchased in-process research and development of $2,603,000 in connection with
the acquisitions of MightyMail Networks, Inc. and Paralogic Software
Corporation, and for the same period ended June 30, 1998 Xoom.com recognized
$330,000 in connection with the acquisition of Paralogic Corporation. For the
six months ended June 30, 1999 Xoom.com recognized the cost of purchased
in-process research and development of $2,603,000 in connection with the
acquisitions of MightyMail Networks, Inc. and Paralogic Software Corporation,
and for the same period ended June 30, 1998 Xoom.com recognized $660,000 in
connection with the acquisitions of Paralogic Corporation and the purchase of
selected assets of Revolutionary Software, Inc.

    MIGHTYMAIL NETWORKS, INC.

    In connection with the MightyMail Networks acquisition, Xoom.com acquired
MightyMail Networks' e-mail platform. The MightyMail platform allows branding
material and marketing content to be placed within person-to-person e-mail that
is sent by individuals to individuals. The MightyMail application runs on an
Oracle database and Unix operating system. All the application code is written
using Java servlets, which are Java applets that run within a Web server
environment. The MightyMail application uses a three-tiered architecture common
to most Internet applications: an interface layer, an application layer, and a
database layer. In addition, MightyMail uses a custom mail agent that links into
a standard mail transfer agent. In the future, Xoom.com expects that this custom
mail agent will be useable by any standard mail protocol for users who wish to
run the MightyMail application in their own mail environment.

    At the time of the acquisition, version 1.0 of the MightyMail technology was
functional as a commercially viable product. However, the current product has
various e-mail options and is not a truly customizable product with a rich
library of content or business user interface. In fact, version 1.0 is
approximately half of the true customizable, rich-e-mail product originally
intended to be developed. At the time of the acquisition, MightyMail Networks
was developing a second version of the MightyMail Networks technology, which was
not completely functional as a commercially viable product. Version 2.0 of the
MightyMail technology will be fully customizable, have access to a rich library
of content, have the ability to add surveys, be compatible with corporate
servers, have e-mail wizards, allow end-users to create their own content and
enable the inclusion of photographs.

    The nature of the remaining estimated efforts necessary to develop version
2.0 of the MightyMail technology include:

    - Integration with Xoom.com's existing webmail system. This integration will
      bring MightyMail capabilities, which includes the ability to compose rich
      e-mail, to Xoom.com's existing account holders, which now exceed 700,000
      users.

    - Re-architecting of the MightyMail platform to be technically compatible
      with the Xoom.com technology infrastructure.  The primary compatibility
      issue will be the integration of Apache Web server technology in place of
      the current Java Web Server from Sun Microsystems.

    As of the date of the technology's valuation, Xoom.com estimated that 50% of
the research and development effort had been completed at the date of
acquisition and expected the remaining research and development efforts relating
to the completion of the version 2.0 MightyMail technology would require
approximately six months of effort from the date of valuation through its
release date in the fourth quarter of 1999. Xoom.com estimated that three
full-time engineers would be required to

                                      164
<PAGE>
complete the in-process projects. These projects included the use of one
full-time engineer for six months to work on the Apache Web server integration
efforts, and two full-time engineers for 6 months to work on the
MightyMail/Xoom.com e-mail integration efforts. Accordingly, Xoom.com has
estimated that the total estimated research and development costs to complete
MightyMail version 2.0 are $170,000. Xoom.com anticipates completion of the
project in the fourth quarter of 1999.

    PARALOGIC SOFTWARE CORPORATION

    In connection with the Paralogic Software Corporation acquisition, Xoom.com
acquired Paralogic Software Corporation's product Anexa.com, a combination of
Web site authoring and community building tools that allows users to instantly
create comprehensive Web sites featuring multi-media albums, discussion forums,
events, chat, news announcements, classified ads, guest books, membership
databases and community administration. In connection with this acquisition
Xoom.com also obtained ParaChat Professional, a chat software that is licensed
to individuals and businesses. This software is hosted by a server and is
supported by a staff of engineers, both of which were acquired in conjunction
with the Paralogic Software Corporation acquisition. This is in contrast to the
purchase of the ParaChat Personal Network, which Xoom.com acquired in connection
with the purchase of Paralogic Corporation in March 1998. The ParaChat Personal
Network is hosted by Xoom.com, and is based on a free chat service that Xoom.com
members can download on to their Web pages.

    At the time of acquisition, the current versions of Anexa.com and ParaChat
Professional did not represent the more robust, feature-rich products that
Paralogic Software Corporation envisioned and intended to develop in the twelve
months following the acquisition date. The future versions of these products are
expected to incorporate a number of significant additional features, including
enhanced scalability as traffic is added, a relational database management
system, support capability, e-mail verification, improved directory services,
search capability, instant messaging, file sharing capability, home page
publishing, additional administration and management tools, calendar and address
book capabilities, polls, gift galleries, greeting cards, voice chat, and white
board functionality. The nature of the remaining estimated efforts necessary to
develop the acquired, incomplete new versions of Anexa.com and ParaChat
Professional into commercially viable products include:

    - ANEXA.COM.  These changes fall into the following categories:

       (A) new features like Paralogic Instant Messenger, support for Uniplanet
           calendar and support for MightyMail mail;

       (B) feature enhancements and upgrades, like Media Albums Plus to handle
           MP3 files, moderated message boards and improved event notification;

       (C) user interface enhancements like administration tools; and

       (D) bug fixing.

    - PARACHAT PROFESSIONAL.  These changes fall into the following categories:

       (A) new features like voice chat and chat using HTML, the computer
           language used to create hypertext documents;

       (B) user interface enhancements and support for moderated events, such as
           the ability to accept or deny audience questions;

       (C) administration tools, like a filth filter and Chat 911 to help manage
           abusive behavior in chat rooms;

       (D) support for internationalization; and

       (E) bug fixing.

                                      165
<PAGE>
    As of the date of the technology's valuation, Xoom.com estimated that 17% of
the research and development effort had been completed at the date of
acquisition and expected the remaining research and development efforts relating
to the completion of the new versions of Anexa.com and ParaChat Professional
technology would require approximately nine months of effort from the date of
valuation through its expected release date of March 2000. These projects
include the use of eight engineers, spending 75% of their time on the project,
for nine months, to create the new versions of the products, at an estimated
total cost to complete of $576,000.

    AMORTIZATION OF DEFERRED COMPENSATION

    Xoom.com has recorded deferred stock compensation charges of $0 during the
three months ended June 30, 1999 and Xoom.com recorded charges of $913,000 for
the same period ended June 30, 1998. Xoom.com has recorded deferred stock
compensation charges of $0 during the six months ended June 30, 1999 and
Xoom.com recorded charges of $972,000 for the same period ended June 30, 1998.
The deferred compensation charges account for the difference between the
exercise price and the deemed fair value of some of the stock options Xoom.com
granted to its employees. Xoom.com cannot guarantee that it will not accrue
additional charges, which could have a material adverse effect on its business,
results of operations and financial condition.

    Deferred compensation reflects the amortization of stock compensation
charges resulting from stock options and restricted stock purchase agreements.
Xoom.com has recorded amortization of deferred compensation of $175,000 during
the three months ended June 30, 1999 and Xoom.com recorded $728,000 during the
same period ended June 30, 1998. Xoom.com has recorded amortization of deferred
compensation of $405,000 during the six months ended June 30, 1999 and it has
recorded $807,000 during the same period ended June 30, 1998.

    AMORTIZATION OF INTANGIBLE ASSETS

    Amortization of intangible assets totaled $1.4 million for the three months
ended June 30, 1999 and it was $346,000 for the same period ended June 30, 1998.
Amortization of intangible assets totaled $2.3 million for the six months ended
June 30, 1999 and it totaled $346,000 for the same period ended June 30, 1998.
The additional amounts recorded in the periods ended June 30, 1999 represent
amortization of intangible assets and goodwill resulting from Xoom.com's
acquisitions of Focused Presence, Inc., MightyMail Networks, Inc., Net Floppy,
Inc., and Paralogic Software Corporation, amortized over periods ranging from 36
to 48 months. The amounts recorded in the periods ended June 30, 1998 represent
amortization of intangible assets and goodwill resulting from Xoom.com's
acquisitions of Paralogic Corporation and Global Bridges Technologies, Inc., and
the purchase of certain assets of Revolutionary Software, Inc., amortized over
periods ranging from 24 to 42 months.

    For the acquisitions in the periods ended June 30, 1999, Xoom.com has
determined the appropriateness of the estimated useful lives related to the
intangible assets based on general and specific analysis. In general, the
Internet is characterized by rapid technological change, changes in users and
customer requirements and preferences, frequent new product and service
introductions and the emergence of new industry standards and practices.

    The market for community-based direct selling channels on the Internet is
new and rapidly evolving, and competition for members, consumers, visitors and
advertisers is intense. In addition, Xoom.com attracts members to its Web site
with a variety of free services, including home pages, e-mail, chat rooms,
electronic newsletters, clip art and software libraries, online greeting cards
and page counters. In order to continue attracting members using these various
methods, the free services must be constantly updated and improved.

    With respect to the purchased technology associated with the business and
technology acquisitions, Xoom.com considered the effects of obsolescence,
demand, competition, and other economic factors.

                                      166
<PAGE>
Due to the rapid technological change involved in the Internet, Xoom.com
estimated that new technologies would replace the intangible assets relating to
the purchased technology within a 36 to 48 month period.

    With respect to the goodwill associated with all of the acquisitions,
Xoom.com considered the effects of obsolescence, demand, competition, other
economic factors and expected actions of competitors and others. Based on these
considerations, Xoom.com determined the positive effect of the acquisitions, and
therefore the life of the goodwill, to be 24 to 48 months.

    OTHER INCOME, NET

    Other income, net represents interest Xoom.com earned on its cash and
investments, offset by interest expense Xoom.com paid on its borrowings.
Xoom.com has recorded approximately $2.4 million in interest income in the three
months ended June 30, 1999 and has recorded $0 in the same period ended June 30,
1998. Xoom.com has recorded approximately $3.0 million in interest income in the
six months ended June 30, 1999 and recorded $0 during the same period ended June
30, 1998. This increase was primarily due to the increased cash balances
available to invest as a result of Xoom.com's initial public offering in
December 1998 and its secondary public offering in April 1999.

    Interest expense represents interest charges related to notes payable and
capital leases. Interest expense recorded in the three months ended June 30,
1999 was approximately $35,000 and interest expense during the same period ended
June 30, 1998 was $0. Interest expense recorded in the six months ended June 30,
1999 was approximately $65,000 and interest expense during the same period ended
June 30, 1998 was $0.

    NET LOSS

    Xoom.com's net loss for the three month period ended June 30, 1999 was $6.7
million, and it was $2.3 million for the same period ended June 30, 1998.
Xoom.com's net loss for the six month period ended June 30, 1999 was $10.1
million, and it was $3.3 million for the same period ended June 30, 1998. The
increase in the net loss for both periods was a result of additional expenses,
primarily in sales and marketing, which were $5.1 million and $7.5 million in
the three and six months ended June 30, 1999, compared to $455,000, and $717,000
in the three and six months ended June 30, 1998. Additionally, Xoom.com's net
loss for the three and six months ended June 30, 1999 and 1998 included costs
resulting from acquisitions such as amortization of goodwill and other
intangible assets, and purchased in-process research and development charges.
During the three and six months ended June 30, 1999, Xoom.com recorded $1.4
million and $2.3 million for the amortization of goodwill and other intangibles,
and Xoom.com recorded $2.6 million related to purchased in-process research and
development in both periods. In the three months ended June 30, 1998,
amortization related to goodwill and other intangibles was $346,000 and
purchased in process research and development charges were $330,000. In the six
months ended June 30, 1998, amortization related to goodwill and other
intangibles was $346,000 and purchased in process research and development
charges were $660,000. The expenses in the three and six months ended June 30,
1999 were partially offset by revenues of $6.5 million and $10.9 million and
interest income of $2.4 million and $3.0 million. The expenses in the three and
six months ended June 30, 1998 were partially offset by revenues of $1.7 million
and $2.5 million.

(1) There were no material costs of advertising revenue during 1997 and 1998.

    Xoom.com's operating expenses have increased significantly in absolute
dollar amounts in each quarter during 1997, 1998 and 1999 as Xoom.com has made
the transition from the development stage to the commercialization of its
services and products and expansion of its business. Xoom.com expects operating
expenses will continue to increase in the future as it continues to seek to
expand its business. To the extent that these expenses are not accompanied by an
increase in net revenue, Xoom.com's business, results of operations and
financial condition could be materially adversely affected.

    Xoom.com expects operating results to fluctuate significantly in the future
as a result of a variety of factors, many of which are outside of its control.

    As a strategic response to changes in the competitive environment, Xoom.com
might from time to time make pricing, service or marketing decisions or pursue
business combinations that could have a material adverse effect on its business,
results of operations and financial condition. In order to accelerate the
promotion of the Xoom.com brand, Xoom.com intends to increase its marketing
budget significantly, which could materially and adversely affect its business,
results of operations and financial condition. Xoom.com expects to experience
seasonality in its business, with user traffic on the Xoom.com site potentially
being lower during the summer and year-end vacation and holiday periods when
overall usage of the Web is lower. Additionally, seasonality may significantly
affect its advertising revenue during the first and third calendar quarters, as
advertisers historically spend less during these periods. As Web-based commerce
and advertising is an emerging market, additional seasonal and other patterns
may develop in the future as the market matures. Any seasonality is likely to
cause quarterly fluctuations in Xoom.com's operating results, and these patterns
could have a material adverse effect on its business, results of operations and
financial condition.

    Due to the foregoing factors, Xoom.com's quarterly net revenue and operating
results are difficult to forecast. Consequently, Xoom.com believes that period
to period comparisons of its operating results will not necessarily be
meaningful and you should not rely on them as an indication of future
performance. It is

                                      169
<PAGE>
likely that in some future quarter or quarters its operating results will fall
below the expectations of securities analysts and investors. In such event, the
trading price of its common stock would likely be materially and adversely
affected.

LIQUIDITY AND CAPITAL RESOURCES

    Prior to Xoom.com's initial public offering, it financed its operations
primarily through the private placement of common stock. On December 9, 1998,
Xoom.com completed its initial public offering of common stock, in which it
issued 4,600,000 shares of common stock at a price of $14.00 per share. Proceeds
from the offering were approximately $57.3 million, net of offering costs. On
April 9, 1999, Xoom.com completed a secondary public offering of its common
stock and issued 4,600,000 shares, including 600,000 shares issued in connection
with the exercise of the underwriter over-allotment option, at a price of $66.00
per share. Of the 4,600,000 shares of common stock sold in the offering,
2,659,800 were sold by Xoom.com and 1,940,200 shares were sold by existing
stockholders. Proceeds from the follow-on offering were approximately $167
million, net of offering costs.

    As of December 31, 1998 and June 30, 1999, Xoom.com had cash and cash
equivalents and short-term investments of approximately $56.6 million and $165.4
million, respectively. Xoom.com regularly invests excess funds in short-term
money market funds, government securities and commercial paper.

    Net cash used in operating activities for the years ended December 31, 1998
and 1997 and for the period from April 16, 1996 through December 31, 1996 was
$3.6 million, $1.4 million and $635,000, respectively. Cash used in operating
activities for the year ended 1997 was primarily the result of net losses,
partially offset by an increase in the contingency accrual. Cash used in
operating activities for the year ended December 31, 1998 was primarily the
result of net losses and an increase in accounts receivable related to the
growth of advertising revenues, partially offset by amortization of intangible
assets related to its acquisitions, amortization of deferred compensation
incurred in connection with the granting of options to employees to purchase
common stock, an increase in current liabilities as a result of the growth of
its business, and a non-cash charge related to the issuance of warrants in
connection with a loan agreement.

    Net cash used in operating activities for the six months ended June 30, 1999
was $5.8 million, and net cash provided by operating activities for the six
months ended June 30, 1998 was $313,000. Cash used in operating activities in
the period ended June 30, 1999 was primarily the result of net losses of $10.1
million and an increase in accounts receivable related to the growth of
advertising revenues of $1.5 million. These amounts were partially offset by
amortization of intangible assets of $2.3 million and in-process research and
development charges of $2.6 million related to Xoom.com's acquisitions,
amortization of deferred compensation incurred in connection with the granting
of options to employees to purchase common stock of $405,000, and an increase in
current liabilities as a result of the growth of its business of $2.6 million.
In the six months ended June 30, 1998, cash provided by operating activities was
primarily the result of net losses of $3.3 million, which were offset by charges
to in-process research and development of $660,000, the amortization of
intangibles of $346,000, and an increase in intangible assets of $1.6 million.

    Net cash used in investing activities for the years ended December 31, 1998
and 1997, and for the period from April 16, 1996 through December 31, 1996, was
$4.7 million, $393,000, and $64,000, respectively. Cash used in investing
activities in each period was primarily related to purchases of fixed assets,
except for the year ended December 31, 1998, in which cash used in investing
activities also included $2 million for the purchase of short-term investments
and $731,000 of net cash for business and asset acquisitions.

    Net cash used in investing activities for the six months ended June 30, 1999
was $158.9 million and it was $863,000 in the same period ended June 30, 1998.
Cash used in investing activities during the six months ended June 30, 1999 was
primarily related to the purchase of marketable securities for $162.5 million.
The cash used in investing activities in each period was also related to
purchases of fixed assets and net cash paid for business acquisitions. From time
to time, we expect to evaluate the acquisition of products, businesses and
technologies that complement our business. These acquisitions may involve cash
investments.

    Net cash provided by financing activities for the years ended December 31,
1998 and 1997 and for the period from April 16, 1996 through December 31, 1996
was $62.8 million, $1.8 million and $700,000, respectively. Cash provided by
financing activities was primarily attributable to net proceeds from the
issuance of common stock and the issuance of notes payable to stockholders. In
addition, for the year ended December 31, 1998, cash provided by financing
activities includes $511,715 received in connection with a secured financing
agreement with a leasing company and $1,250,000 received in connection with a
loan agreement. For the year ended December 31, 1998, cash provided by financing
activities also included cash received from the issuance of 4,600,000 shares of
common stock upon the completion of its initial public offering. Proceeds from
the offering were approximately $57.3 million, net of offering costs. The cash
generated by financing activities in 1998 was offset by $3.2 million used to
repay notes payable.

    Net cash provided by financing activities for the six months ended June 30,
1999 was $167.5 million and it was $4.6 million for the same period ended June
30, 1998. Cash provided by financing activities in the six months ended June 30,
1999 was primarily related to proceeds from Xoom.com's secondary public
offering, partially offset by the repayment of notes payable. Cash provided by
financing activities in the six months ended June 30, 1998 was primarily
attributable to net proceeds from the issuance of common stock, partially offset
by the repayment of notes payable.

    As of June 30, 1999, Xoom.com's principal commitments consisted of
obligations outstanding under operating and capital leases. Although Xoom.com
has no material commitments for capital expenditures, it anticipates a
substantial increase in its capital expenditures and lease commitments
consistent with anticipated growth in operations, infrastructure and personnel.
Also, in the future Xoom.com may require a larger merchandise inventory in order
to provide better availability to customers and achieve purchasing efficiencies.

    As of December 31, 1998 and June 30, 1999, Xoom.com had a total of $1.7
million and $1.4 million, respectively, in notes payable relating to its
acquisitions. This includes a non-interest bearing note payable in the amount of
$1.1 million payable to the stockholders of Paralogic Corporation in minimum
monthly installments of $30,000 through September 1999, including additional
payments up to $860,000 based on performance measurements. Total notes payable
also includes a note payable of $47,500, which bears interest at a rate of 5%
and is due in equal monthly payments of $2,500 through August 2000 to the
stockholders of Global Bridges.

    In the year ended December 31, 1998, Xoom.com issued warrants to purchase a
total of 314,747 shares of common stock at a price of $3.33 per share. These
warrants were exercised prior to its initial public offering on December 9,
1998.

    On October 1, 1998, Xoom.com entered into a secured financing agreement with
a leasing company. The agreement provides for borrowings of up to a cumulative
amount of $1.0 million through July 31, 1999. As of June 30, 1999, its
outstanding principal balance under this agreement was approximately $455,000.

    On November 3, 1998, Xoom.com entered into a secured loan agreement, which
provided for borrowings of up to $2,750,000. In November 1998, Xoom.com borrowed
$1,250,000 under this agreement. Under the terms of the loan agreement, Xoom.com
agreed to issue the lender a warrant to purchase up to 183,333 shares of common
stock at an exercise price equal to $14 share. Xoom.com recorded a non-cash
charge classified as a non-operating expense of approximately $1.5 million
during the fourth quarter of 1998 based on the fair value of this warrant. As of
December 31, 1998, all interest and principal amounts had been fully paid, and
the loan agreement had been canceled. On January 11, 1999, the lender exercised
the warrants in a net exercise transactions and purchased 116,231 shares of
Xoom.com's common stock at a price of $14 per share. The effective interest rate
on this secured loan agreement for the year ended December 31, 1998 was
approximately 1,450%.

    Xoom.com believes that it has the financial resources needed to meet its
presently anticipated business requirements, including capital expenditure and
strategic operating programs, for at least the next 12 months.

                                      171

Thereafter, if cash generated by operations is insufficient to satisfy its
liquidity requirements, Xoom.com may need to sell additional equity or debt
securities or obtain additional credit facilities. The sale of additional equity
or convertible debt securities may result in additional dilution to its
stockholders. Xoom.com may not be able to raise any such capital on terms
acceptable to Xoom.com or at all.

DISCLOSURES ABOUT MARKET RISK

    Xoom.com's exposure to market risk is principally confined to its short-term
available-for-sale securities, which have short maturities and, therefore,
minimal and immaterial market risk.

YEAR 2000 COMPLIANCE

    Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. As a result, software that
records only the last two digits of the calendar year may not be able to
distinguish whether "00" means 1900 or 2000. This may result in software
failures or the creation of erroneous results.

    Xoom.com has conducted an internal review of software systems which it uses
for site management, network monitoring, quality assurance, transactions
processing and fulfillment services. Because Xoom.com developed these software
systems internally, beginning at inception in 1996 when the Year 2000 problem
already had some visibility, Xoom.com was largely able to anticipate four digit
requirements. In conjunction with ongoing reviews of its own products and
services, Xoom.com is also reviewing its computer infrastructure, including
network equipment and servers. Xoom.com does not anticipate material problems
with network equipment, as its current configuration was installed within the
last three years. Similarly, Xoom.com purchased most of its servers in 1997 and
1998. With this relatively current equipment, Xoom.com does not anticipate
material Year 2000 compliance problems, and Xoom.com will replace any servers
that cannot be updated either in the normal replacement cycle or on an
accelerated basis. Xoom.com has also internally standardized its personal
computers on Windows NT 4.0, using reasonably current service packs, which its
vendor has advised Xoom.com are Year 2000 compliant. Xoom.com uses multiple
software systems for internal business purposes, including accounting, e-mail,
development, human resources, customer service and support and sales tracking
systems. All of these applications have been purchased within the last three
years.

    Xoom.com has made inquiries of vendors of systems Xoom.com believes to be
mission critical to its business regarding their Year 2000 readiness. Although
Xoom.com has received various assurances, Xoom.com has not received affirmative
documentation of Year 2000 compliance from any of these vendors and Xoom.com has
not performed any operational tests on its internal systems. Xoom.com generally
does not have contractual rights with third party providers should their
equipment or software fail due to Year 2000 issues. If this third party
equipment or software does not operate properly with regard to Year 2000,
Xoom.com may incur unexpected expenses to remedy any problems. These expenses
could potentially include purchasing replacement hardware and software. Xoom.com
has not determined the state of compliance of some of its third-party suppliers
of services such as warehousing and fulfillment services, phone companies, long
distance carriers, financial institutions and electric companies, the failure of
any one of which could severely disrupt its ability to carry on its business.

    Xoom.com anticipates that its review of Year 2000 issues and any remediation
efforts will continue throughout calendar 1999. The costs incurred to date to
remediate its Year 2000 issues have not been material. If any Year 2000 issues
are uncovered with respect to these systems or its other internal systems,
Xoom.com believes that Xoom.com will be able to resolve these problems without
material difficulty, as replacement systems are available on commercially
reasonable terms. Xoom.com presently estimates that the total remaining cost of
addressing Year 2000 issues will not exceed $200,000. Xoom.com derived these
estimates using a number of assumptions, including the assumption that Xoom.com
has already identified its most significant Year 2000 issues. However, these
assumptions may not be accurate, and actual results could

                                      172
<PAGE>
differ materially from those anticipated. In view of its Year 2000 review and
remediation efforts to date, the recent development of its products and
services, the recent installation of its networking equipment and servers, and
the limited activities that remain to be completed, Xoom.com does not currently
expect that the Year 2000 issue will pose significant operational problems.
However, delays in the implementation of new information systems or a failure to
fully identify all Year 2000 dependencies in Xoom.com's existing system and in
the systems of its suppliers could harm Xoom.com's business. Therefore, Xoom.com
is developing, but does not yet have, contingency plans for continuing
operations in the event these problems arise.

    Xoom.com's applications operate in complex network environments and directly
and indirectly interact with a number of other hardware and software systems.
Xoom.com is unable to predict to what extent its business may be affected if its
systems or the systems that operate in conjunction with it experience a material
Year 2000 failure. Known or unknown errors or defects that affect the operation
of its software and systems could result in delay or loss of revenue,
interruption of services, cancellation of contracts and memberships, diversion
of development resources, damage to its reputation, increased service and
warranty costs, and litigation costs, any of which could adversely affect
Xoom.com's business, financial condition and results of operations. The most
likely worst case scenario is that the Internet fails and Xoom.com is unable to
offer any services on its community site or make any of its direct e-commerce
offerings.

                                 SNAP BUSINESS

OVERVIEW


    Snap.com has been one of the fastest-growing major portals on the Web from
July 1998 to July 1999, according to data provided by Media Metrix based on the
percentage increase in reach among home and work users. Snap.com is a free,
comprehensive information, navigation and content aggregation service targeted
at both consumer and business users. SNAP utilizes proprietary technology to
integrate the vast resources of the Internet into a single user interface. SNAP
encourages users to rely on Snap.com to meet their personal daily information
needs, such as financial portfolio tracking, e-mail service and local weather
data, as well as to satisfy their varied and unpredictable Internet search
needs.


    SNAP creates an Internet experience for each user that is simple and
tailored to the user's specific demands by combining robust content obtained
from numerous content providers with personalization capability through MySnap.
Snap.com delivers relevant search results using a hand-built search directory,
together with proprietary content harvesting, data management and response
compilation technologies. In addition to providing a specific and relevant
response to a search, Snap.com also directs the user to related content
resources of the Web through a single interface. SNAP believes that users
respond better to a service that aggregates specific and relevant responses to
queries with additional "sticky" content such as related Web sites and
discussion groups. Snap.com enhances this content by allowing a user to create
his or her own daily information service, as well as offering personal
productivity services such as a reminder feature. While many of SNAP's direct
portal competitors may provide a similar range of services, SNAP believes it
offers a unique combination of these services. In addition, SNAP offers users
the ability to access rapidly-evolving forms of content such as streaming video
and audio through advanced technologies such as Snap.com For Higher Speed Users.

    In addition, SNAP uses its SnapLENS-TM- technology to provide customized
services to significant third party distribution partners such as RealNetworks,
GTE and Sony. This enables SNAP to develop co-branded navigation and content
aggregation sites with a special focus on the partner's content. This also
enables these partners to communicate specialized information to users while
SNAP benefits from increased user traffic and brand awareness. By assuring a
robust experience to attract and keep users, together with its ability to
coordinate on-air promotional opportunities through its strategic relationship
with NBC, SNAP believes that Snap.com delivers better value to advertisers by
combining broad audience reach and segmentation and measurement capability to
better target an advertiser's message.

    SNAP's reach among home and work users increased more than 200% in the
thirteen months since NBC acquired its equity interest in SNAP, from less than
5% in July 1998 to 14% in July 1999, according to Media Metrix. SNAP's
registered users increased from approximately 16,000 at the end of June 1998 to
more than 3.0 million at the end of August 1999, adding approximately 10,000 new
members per day for the last 30 days. SNAP believes that the rapid growth
generated by television and other promotions, as well as distribution
partnerships, indicates the potential for significant future growth in reach and
membership, positioning SNAP to increase its audience size and scale to make
Snap.com uniquely attractive to advertisers. For the quarter ended June 30,
1999, SNAP increased revenues approximately $2.6 million, or 49% compared with
the preceding calendar quarter. Quarterly net revenue increased from
approximately $1.1 million for the second quarter of 1998 to $80 million for the
second quarter of 1999, representing compound quarterly sales growth of
approximately 64%. Quarterly net losses were approximately $21.8 million and
$5.1 million in the second quarter of 1998 and 1999, respectively.

                                      174

    Snap.com was launched as "SNAP" by CNET in September 1997. In June 1998, NBC
and CNET formed SNAP! LLC as a Delaware limited liability company to conduct the
operations of Snap.com. SNAP's headquarters are located in San Francisco,
California.

PORTAL INDUSTRY BACKGROUND

    The rapid growth in content on the Internet, combined with its unindexed
nature, presents a significant challenge to users seeking the information and
resources the Internet offers. Prior to the development of navigational tools,
users had to know a lengthy Web address for each specific site or rely on
hypertext links between Web sites to locate relevant information. Content
providers and advertisers also faced difficulties in making the existence and
location of their Web sites widely known and available to their target
audiences.

    Web directories and search engines were developed to assist users in
locating information on the Internet. Directories are typically compiled by a
staff of editors, and list Web sites by specific topics of interest. Directories
generally list Web sites by hypertext address, enabling a user to go directly to
the listed site by clicking on the address. Entries in a directory also may
contain Web site descriptions or reviews. Search engines offer users the ability
to search Web sites based upon specific word or phrase queries. Search engines
typically use automated software that "crawls" the Web to continuously capture
and store updated Web site information. The information is then indexed in a
database in order to provide immediate retrieval of relevant Web site listings
in response to a user's query.

    Although search engines and directories help users navigate the Web, SNAP
believes that there is an opportunity to provide added value to the user
experience by offering:

    - Breadth and depth of content, unique in its relevance to user demands,

    - Highly accurate search results, generated by a hand-built search
      capability together with proprietary content harvesting, data management
      and response compilation technologies,

    - Personalization capability for frequently-requested daily information such
      as financial data, sports scores and local weather, and

    - Access to leading edge technologies such as rich media streaming.

THE SNAP STRATEGY

    SNAP's objective is to establish itself as one of the leading branded
service providers for media navigation and content aggregation on the Internet.
SNAP seeks to provide a readily-accessible, content-rich Web experience to meet
users' demands and to establish the SNAP Web site as a highly attractive
platform for advertisers and e-commerce partners. Key elements of SNAP's
strategy include:

    LEVERAGE MULTIPLE MEDIA PLATFORMS

    SNAP intends to leverage its access to multiple media platforms to enhance
the user experience and to attract advertisers. SNAP has been able to offer a
variety of program integration opportunities across on-line and traditional
broadcast media because of its strategic relationship with NBC. As a result,
SNAP is positioned to attract broadcast viewers to Snap.com. In addition to
pursuing on-air visibility and cross-marketing opportunities, SNAP seeks to
capitalize on successful NBC television programming in promoting Snap.com. For
example, in promotions aired during NBC's encore broadcast of "Schindler's List"
in March 1999, television viewers were directed to Snap.com for a comprehensive
collection of Holocaust research, information and links available on the Web.
SNAP will continue to pursue an integrated strategy capitalizing on multiple
media platforms for marketing, promoting and sharing content, which SNAP refers
to as its "trans-media" capability. SNAP believes

                                      175
<PAGE>
that its trans-media capability is unique and will enable it to provide a richer
offering that is more attractive to users.

    Moreover, SNAP's trans-media capability allows it to provide coordinated
marketing opportunities to its advertising customers and enables SNAP to
increase awareness of the SNAP brand through promotion on NBC. By offering
on-line advertising inventory in coordination with NBC's broadcast and cable
advertising sales opportunities, SNAP can offer a variety of cross-promotional
opportunities for advertisers. This is attractive to many advertisers as it
offers broadcast and cable reach as well as the measurable demographic
information that Web advertising allows. SNAP intends to continue to leverage
its relationship with NBC and its unique trans-media capability to become the
preferred online option for advertisers.

    EXPAND AND ENHANCE ON-LINE CONTENT AND SERVICES

    SNAP seeks to establish itself as a leader in the Internet navigation and
content aggregation market by offering the broadest variety of high quality
content. SNAP seeks to enhance its users' Internet experience by providing
access to leading edge technologies, such as higher bandwidth platforms allowing
rich media streaming. SNAP intends to use its technological capability to group
together users with similar interests in order to meet the demand for real-time
interaction among users. By expanding and enhancing the breadth and
functionality of SNAP's online services and personalization features, SNAP
believes that it can strengthen the SNAP brand and increase user loyalty.

    MAINTAIN AND EXTEND LEADERSHIP IN SEARCH TECHNOLOGY

    SNAP's search service utilizes a hand-built search directory and proprietary
content harvesting and data management technologies. This enables Snap.com's
users to access robust content aggregated from numerous content providers,
delivering a search capability that is intelligent, comprehensive and readily
accessible to the user. SNAP believes that its search functionality is
differentiated from many other search engines and directories because of its
combination of hand-built and automated technology. As new media such as audio
and video streaming become more prevalent on the Internet, SNAP's strategy is to
expand and enhance its universal search capability to access all potential
resources in a single search.

    INCREASE ADVERTISING EFFECTIVENESS THROUGH CROSS PROMOTION AND COMMUNITY
     SEGMENTING

    SNAP believes it can leverage its strategic relationship with NBC to offer
advertisers cross-promotion capability by coordinating network advertising with
a variety of advertising opportunities on Snap.com. Through its relationship
with NBC, SNAP has the ability to coordinate advertising strategies to reach
NBC's substantial broadcast and cable television viewing audience. In addition,
the capabilities of the Internet have increased advertisers' emphasis on
tracking users carefully to connect with audiences that fit specific buying
profiles. Targeted "narrowcast" Internet advertising campaigns, through
directory and channel ads or keyword ads, provide opportunities to engage in
high response, product-specific advertising. In order to provide such audiences
to advertisers, services and sites must develop technologies to enable them to
conduct complex demographic profiling of consumers. SNAP has developed a
registration methodology and underlying databases that enable it to
differentiate among users. Through user segmentation SNAP intends to continue to
provide highly-targeted content selected by SNAP's editors in conjunction with
related e-commerce opportunities, increasing the effectiveness of advertising
messages.

                                      176
<PAGE>
    MAXIMIZE REACH THROUGH DISTRIBUTION CHANNELS

    SNAP intends to expand its user base and reach through multiple distribution
channels including co-branding relationships, creation of affinity groups and
community building. SNAP's innovative SnapLENS system enables the rapid and
cost-effective creation of custom branded versions of the Snap.com site, with a
unique "look and feel," customized content and targeted advertising
opportunities. SnapLENS enables SNAP to become the default co-branded home page
or search engine on third party Internet sites. The SnapLENS technology is a key
component of SNAP's distribution model. The SnapLENS technology allows SNAP to
generate, manage and operate unique editions of the site for an expanding group
of Internet service providers, PC manufacturers and other SNAP distribution
partners. Similarly, SNAP believes that it can increase its reach by customizing
its service for special affinity groups and user communities.

    CAPITALIZE ON BROADBAND CAPABILITY

    SNAP intends to continue to invest in resources that will enable it to
address future developments in Internet technology and architecture such as
platform transitions or expansions. SNAP believes that it is well-positioned to
provide its services in the Internet environment of the future as the Internet
infrastructure evolves. The emergence of broadband Internet access has led to
increased demand for broadband content. SNAP's relationships with a wide array
of content providers position SNAP to take advantage of this development.
Furthermore, as the Internet expands to connect to diverse devices other than
computers, SNAP believes its robust searching technology will allow it to
provide access to Internet resources, regardless of location or mode of
delivery. SNAP intends to continue to invest in its technology and services to
be well-positioned for the Internet of the future.

PRODUCTS AND SERVICES

    Through Snap.com, its flagship service, and Snap.com For Higher Speed Users,
SNAP offers users a free information, navigation and content aggregation
service. This service is targeted at both consumer and business users, enabling
them to access and personalize the vast resources of the Internet. SNAP
optimizes users' access to rapidly-evolving forms of content such as rich media
streaming through advanced technologies such as Snap.com For Higher Speed Users.
SNAP also enables users to purchase goods and services, interact in community
chat and bulletin board environments and communicate through free e-mail, search
classified advertisements, make travel arrangements and engage in a wide variety
of other Internet activities aggregated on the service.

    Snap.com and Snap.com For Higher Speed Users offer users a powerful way to
search and organize the vast resources of the Internet. Logically arranged to
give users a quick route to the best of what they are looking for on the Web,
Snap.com and Snap.com For Higher Speed Users provide efficient, high-quality
Internet search results and directory listings based on broad, intelligently
selected content. At the heart of SNAP's portal services is a directory of Web
sites and over 500 SNAP "Guides to", hand built and continually updated by a
team of producers and reviewers to ensure quality, freshness and relevance.
Users may either search the SNAP directory by using keywords, or browse through
the directory's 16 topic categories. By integrating the capabilities of a search
engine and a directory, SNAP packages specific responses to search queries with
information that may include relevant Web content, branded third party content
and targeted, related advertising and e-commerce opportunities. By aggregating
information around a user's specific interest, SNAP believes that Snap.com and
Snap.com For Higher Speed Users meet the needs of consumers and business to
access relevant and related information, the needs of content providers to reach
interested audiences and the needs of advertisers to deliver advertisements to a
targeted group of potential buyers.

    Snap.com offers selected content from over 100 leading Web publishers
integrated with information from over 300,000 third party Web sites and 55,000
categories. If a particular result is not

                                      177
<PAGE>
found in SNAP's own directory, the search result is served on SNAP from
Inktomi's index of over one hundred million Web pages, for which SNAP pays a
fee. According to research conducted by the NEC Research Institute, SNAP is one
of the top three search engines based on the number of Web sites indexed. SNAP
believes that all of these features provide a comprehensive and seamless search
experience for the user. SNAP focuses on establishing relationships with premium
content providers noted for their depth and accuracy of information. SNAP
typically does not enter into exclusive content relationships, in order to
maintain editorial independence and preserve the flexibility to select
intelligently from the variety of sources which a user can access. SNAP's
presentation model directs users to third party content through the Snap.com
site's "look and feel," while allowing a content provider to maintain its
content within the "look and feel" of its own site, enabling SNAP to aggregate
third party content without expending significant resources to repackage the
information for the user. SNAP believes that through Snap.com, content providers
gain increased exposure to interested users since these users are linked to
broader communities of related content when undertaking search requests.
Moreover, because the range and breadth of material on the Web is often
confusing for consumers, SNAP believes that branded, credible information
providers are valuable elements of its content pool. Snap.com enhances the user
experience by including intelligently compiled editorial material from premium
branded content providers such as MSNBC, iVillage, Women.com (HomeArts), InsWeb,
Weather Labs and E! Online, among others.

    Snap.com and Snap.com For Higher Speed Users integrate multiple methods of
obtaining information from the Internet. Users are presented with five principal
resources--Search, Directory, Content Harvests, SNAP "Guides to" Resource
Centers, and Sponsored Links--from which they can launch specific queries,
browse the Web, access proprietary content and organize content in a
personalized format.

    SEARCH

    SNAP's Search capability allows the user to execute query-based searches of
the Web and other premium content databases or the SNAP Directory. A search can
be effected using either simple keywords, phrases or full text natural language
searches. In addition to its general search function, Snap.com also offers
Advanced Search capability, which gives users a more focused or "search only"
service to exploit fully SNAP's technology and search the Web using either
natural language queries or special search expressions. A search using Advanced
Search will return only a list of relevant Web pages and exclude related
information included in a general Snap.com search, and can be tailored to
retrieve information by date, language, location or media type, such as audio or
video clips. For every search, SNAP's innovative response compilation technology
gives users ready access to highly relevant results via targeted links to
related URLs. In addition, SNAP uses exclusive licensed technology to
intelligently rank search results based on the popularity and freshness of the
Web sites to which the user is referred.

    DIRECTORY

    The SNAP Directory is a hierarchical listing of Web pages that have been
selected and summarized by SNAP and organized by category. The SNAP Directory
enables a user to click on a Directory entry such as Health or Entertainment and
look through a hierarchy of relevant Internet sites for areas of interest. For
example, under Entertainment, the user can proceed from Entertainment to Books
to Authors and finally to Oscar Wilde. Directory assists the user by providing
abstracts of each Directory entry. The Directory is hand built by SNAP editors,
and therefore searches through the Directory return more accurate results than
searches through most competitors' directories, which are compiled mechanically.
As of July 1, 1999, SNAP had increased its directory to over 300,000 entries.
According to Media Metrix, in July 1999 Snap.com was the sixth ranked search
engine based on its reach among home and work users.

                                      178
<PAGE>
    CONTENT HARVESTS

    Content harvests from a variety of third party services provide users with
high quality, up-to-date information from a wide array of familiar and highly
reputable sources. For example, MySnap offers users access to the latest
business, world, technology, cultural and sports information from a variety of
data sources including MSNBC, CNET and the BBC. With CNET, SNAP co-developed an
innovative system for efficiently harvesting, managing and delivering content
and links to content from content providers in accordance with a predefined
schedule, giving users access to regular updates of rapidly changing
information, such as breaking news from news partner MSNBC as well as sports
scores, financial data and weather updates. These content harvests allow SNAP to
provide the high volume of information that consumers and businesses demand,
without expenditure of significant resources by SNAP to generate and update this
data.

    SNAP "GUIDES TO" RESOURCE CENTERS

    SNAP has created SNAP "Guides to" resource centers to provide a
comprehensive, targeted first stop for searches in popular areas of interest on
Snap.com. SNAP's "Guides to" serve as "mini-portals", delivering intelligently
compiled search results in over 500 niche areas of interest. In addition,
because SNAP product managers can build "Guides to" and assemble relevant
content quickly, SNAP has used "Guides to" to build search capability
opportunistically around topics of current interest as well as contextual
programming developed through SNAP's strategic relationship with NBC. For
example, as the international defense and relief effort in the Balkans advanced,
SNAP created a Kosovo Relief Resource Center with the relief organization CARE,
enabling users to link to information about participating in refugee relief
efforts, as well as maps and related information via a single query. NBC viewers
were directed to Snap.com and the Kosovo Relief Resource Center for more
information on events in Kosovo through promotions created by SNAP. Other SNAP
resource centers, such as Insurance Center, Auto Center and Real Estate Center,
provide users with the most relevant tools and information organized around key
areas of interest. Resource centers provide full-service access to information
sources as well as to e-commerce opportunities, enabling users to commence and
complete transactions, from locating a source of information about a particular
service or product, to identifying appropriate providers, and finally to
consummating a transaction for the specific product or service needed.

    SPONSORED LINKS

    Users can be linked directly to third party sites by clicking on several
different ad banners and buttons listed at the side of the search screen or
icons presented on the Snap.com home page. Standard Internet advertising on
Snap.com contains direct links to the advertiser's home page. Without direct
hypertext links such as these a user must either conduct a new search or know
and enter a precise URL to move to another site.

    MYSNAP

    With MySnap, SNAP has developed a number of personalization tools to allow
users to compile and format Internet content and advertising information
according to their specific interests. This encourages users to make Snap.com an
integral part of their daily routine by offering access to regularly-needed
content in a format determined by the user. MySnap allows users to create
permanent filters for continually changing Internet-based information such as
stock quotes, weather and sports scores, compile linked news headlines in
selected categories, and access personalized locally-relevant information such
as movie and television listings simply by entering a zip code. In addition,
MySnap offers e-mail and a reminder feature that users would otherwise manage
using desktop software, enabling users to enhance the power of a connected
network with access to value-added Internet content. MySnap seeks to complement
SNAP's comprehensive search functionality by positioning

                                      179
<PAGE>
Snap.com and Snap.com For Higher Speed Users as a single source for users'
recurring information needs as well.

    SNAP.COM FOR HIGHER SPEED USERS

    Snap.com For Higher Speed Users, launched in March 1999, uses innovative
technology to optimize users' access to rapidly-evolving forms of content,
creating a richer Internet experience including video, audio, animation and
gaming. Snap.com For Higher Speed Users enhances and supports the core
functionality of Snap.com by offering multimedia content and navigation services
to the expanding number of users with high-speed Internet access. Snap.com For
Higher Speed Users features rich media content in all Snap topic categories.
Users can easily switch to the higher speed service from a prominent link
displayed on the home page of Snap.com. By positioning Snap.com For Higher Speed
Users as another "view" into the Internet, SNAP is able to offer navigation and
targeted content to users able to view video clips, hear audio files and
participate in other interactive features that typically perform less well in a
lower bandwidth environment. In addition, because Snap.com For Higher Speed
Users is positioned as an alternative view rather than a separate product
experience, users can switch easily between Snap.com and Snap.com For Higher
Speed Users while keeping all of their personalization and membership settings
intact. SNAP believes this continuity and ease of transit between the two sites
encourages users to access its services at work and at home, irrespective of
variations in access to high-speed technologies.

    SNAPLENS

    To serve the needs of its distribution partners and increase traffic, and
consequently brand awareness, SNAP created the innovative SnapLENS-TM- system to
produce custom versions of the Snap.com portal for specific audiences. With
SnapLENS, Snap.com and Snap.com For Higher Speed Users become the default
co-branded home pages and Internet portals for some third party Internet sites,
including those of RealNetworks, GTE and Sony. SnapLENS allows the rapid and
cost-effective creation of custom branded versions of Snap.com, with a unique
look and feel, customized content and targeted advertising opportunities. The
SnapLENS technology enables SNAP's distribution model, allowing it to generate,
manage and operate unique editions of the site for over 50 Internet service
providers, PC manufacturers and other SNAP distribution partners. SnapLENS
benefits both advertisers and third party hosts by allowing advertisers to
increase the reach and frequency of their messages and enabling third party
sites to more easily sell their advertising space.

STRATEGIC ALLIANCES

    SNAP's primary strategic alliance is with its principal equity holders, NBC
and CNET. Upon formation of SNAP in June 1998, 4 employees of NBC and 120
employees of CNET also joined the SNAP staff in San Francisco.

    In the thirteen-month period from NBC's acquisition of an equity interest in
SNAP through July 31, 1999, SNAP has obtained promotion on the NBC television
network worth in excess of $42 million. Since July 1998, SNAP has increased its
monthly reach among home and work users by more than 211%, to 14%, and increased
the number of unique users per month by 236%, to approximately 8.8 million in
July 1999.

    In addition to co-developing a number of technologies used by SNAP, SNAP and
CNET also have a preferred carriage arrangement. Until May 9, 2000, SNAP is the
preferred general content aggregation service on all CNET web sites, except for
links to Web sites of SNAP competitors, which CNET may provide as part of
editorial content such as news, and such service is branded as SNAP. CNET has
agreed not to enter into a relationship with a SNAP competitor that allows the
competitor to co-brand a general Internet portal service with the CNET brand.
CNET also has agreed, on behalf

                                      180
<PAGE>
of itself and its controlled subsidiaries, not to invest in, develop or operate
a broad-based information, navigation and content aggregation service in
competition with SNAP until May 9, 2000.

    NBC also has a carriage arrangement with SNAP, which gives SNAP the ability
to provide news, finance and sports content from NBC-controlled Web sites on
Snap.com. SNAP is also able to expand its users' ability to access local content
by providing links to NBC-IN.com Web sites and by including each of those Web
sites in SNAP's Directory listings for the cities in which the local stations
are located.

REVENUE SOURCES

    Snap.com provides advertisers with the ability to undertake measurable,
targeted, cost-effective and interactive advertising to a broad audience of
Internet users. Users may arrive at Snap.com via promotional initiatives
co-developed by SNAP and NBC, as well as through traditional Internet search
demand and specific channel alliances with third parties using the SnapLENS
technology. In addition to offering the ability to coordinate advertising
strategies to reach NBC's broadcast audience, which averaged 156 million viewers
per week during the 1998 - 1999 television season, SNAP's services provide
advertisers with the flexibility to reach the mass audience of the Internet by
advertising on general search pages of Snap.com, to target special interest
groups by placing advertisements on directory and channel pages, or to
narrowcast advertisements for specific audiences by keyword advertising and
content and usage affinities. Through the use of its innovative search and
retrieval technologies, SNAP will be able to link highly-targeted,
producer-selected content with specific e-commerce opportunities, increasing the
effectiveness of advertising.

    Traditional advertising on Snap.com includes a wide variety of Internet
media units such as buttons, banners, windows, portals, text links and e-mail,
among others. These placements appear on the Web page when a user enters the
service, performs a search, or browses through the Directory or through the
"Guides to" resource centers. Advertising revenues represented 100% of SNAP's
total revenues in 1998 and the first six months of 1999. SNAP believes it has
been able to generate advertising revenues to date primarily through the
extensive knowledge and relationship base of its direct-sales force, through the
products and technological advantages it can offer advertisers, and through its
strategic relationship with NBC which enables advertisers to leverage
traditional on-air advertising reach.

    SNAP offers advertisers three principal advertising options that may be
purchased individually or in packages: run-of-site, topic channels and keyword
search results. These options all contain hypertext links to the advertiser's
home page. Run-of-site advertisements are media units that appear throughout
Snap.com when a user browses through general search and other less-targeted
sections of the site. Current prices for run-of-site placements range from $18
to $22 per thousand page views. Topic channels advertisements appear when a user
browses through Snap.com's topic channels such as Business & Money, Computing &
Internet, Entertainment or Travel. These advertisements allow advertisers to
target an audience with a specific area of interest. Because of the greater
selectivity of the audience relative to general search pages, current prices for
topic channels advertisements range from $20 to $55 per thousand page views,
depending on the specific channel selected. Keyword advertisements offer the
advertiser a highly targeted, self-selected audience, appearing when a Snap.com
user's search contains a particular keyword purchased by the advertiser. Through
its innovative advertising management system, SNAP tracks every word queried by
Snap.com users, and is able to identify keywords most frequently queried by
Snap.com users and requested by advertisers. The current rate card for keyword
advertisements ranges from $55 to $72 per thousand page views, depending on the
degree of exclusivity requested by the advertiser.

    In addition to revenue from traditional Internet advertising placements,
SNAP's advertising revenue includes fees charged for production and integration
of content, click-throughs, revenues

                                      181
<PAGE>
generated for user subscriptions to free services offered and revenue-sharing
relationships with a limited number of significant clients. SNAP offers selected
clients prominent placement on specific content areas in the Snap Directory and
the "Guides to" resource centers. This enables advertisers to target audience
groups based on content and usage affinities. Through its relationship with NBC,
SNAP has a special ability to coordinate trans-media advertising, allowing
customers to drive traffic from the NBC television viewing audience to the
directed Internet resources available to users via Snap.com.

    SNAP has licensed the Accipiter-TM- system for the instantaneous placement
of advertisements with targeted audiences on appropriate Snap.com Web pages,
augmenting the system with internally developed proprietary additions to enable
SNAP to track its users, manage advertising inventory and protect exclusive
placements. SNAP's technology additionally enables clients to monitor the
effectiveness of their advertisements by tracking click-through rates to learn
more about their target audiences. SNAP advertising sales representatives work
closely with advertisers to understand the data provided by users and apply it
to improve their advertising strategies. SNAP is exploring new technologies to
enhance user behavior tracking and advertising management capabilities.

    During 1998, over 150 advertisers placed advertisements on SNAP's service.
For the six months ended June 30, 1999, Mail.com comprised 29% of SNAP's net
revenues. No single advertiser accounted for 10% or more of SNAP's revenues for
the year ended December 31, 1998. To date, most of SNAP's contracts with large
advertisers have terms of one year or more.

    As of August 31, 1998, SNAP's advertising sales force and account management
group consisted of 80 employees located in San Francisco and New York, with
advertising, business development and account management experience including
experience at media companies such as NBC, Time Warner, Ziff Davis and CNET.
SNAP believes that having an internal sales force with significant prior
experience enables it to better understand and meet advertisers' needs, increase
its access to potential advertisers and maintain strong relationships with its
existing base of advertising clients.

MARKETING

    SNAP's trans-media strength has driven growth through a powerful brand
awareness campaign on the NBC television network, which commenced in July 1998.
SNAP's strategy is to leverage the promotional reach of NBC to turn television
viewers into Snap.com visitors and registered members. SNAP develops its link to
these members by sending them direct e-mail updates and offers that they may
elect to receive during registration. SNAP believes a permission-based method
for ongoing marketing fosters retention and user loyalty.

    National promotional spots began airing on NBC in July 1998 and were
integrated into NBC's fall television season to stimulate awareness of Snap.com.
SNAP has further stimulated brand awareness and user demand through integrated
marketing elements including outdoor and radio advertising, and online
advertising, promotions and sponsorships. SNAP also seeks to leverage the
marketing reach of its distribution partners and content providers through a
range of joint marketing programs such as the SnapLENS initiative, thus
differentiating SNAP from many of its competitors. In addition, SNAP cross-
promotes its services with content providers though advertising swaps in both
traditional and online media.

    Since February 1999, Snap.com has been listed as a search and navigation
service on Netscape's Netcenter Web site accessible via the "Internet Search"
button, for which SNAP pays Netscape a fee based in part on the number of visits
to Snap.com initiated through Netscape. Netscape currently displays eight
premier providers, including Snap.com, on an equal placement basis, and has
agreed to limit the total number of premier providers to nine. SNAP's agreement
with Netscape has a term of one year, expiring June 30, 2000.

                                      182

TECHNOLOGY AND INFRASTRUCTURE

    SNAP believes it can differentiate Snap.com by developing innovative
proprietary technology and integrating high-quality technology licensed from
third parties where appropriate. SNAP's strategy is to develop and license only
technologies that are able to scale with the growth in content, in order to
enable SNAP cost-effectively to adapt and grow with the Internet.

    SNAP's current search engine technology was developed by SNAP based on a
collection of third party licensed proprietary tools. SNAP engineers developed
an enhanced search technology to offer an approach to information retrieval that
provides users enhanced levels of accuracy, currency, comprehensiveness and
speed. The SNAP search engine includes built-in ranking algorithms with search
features geared toward advanced users, accessing producer-selected content from
over 100 leading Web publishers and information from over 300,000 third party
Web sites while utilizing Inktomi's index of over one hundred million Web pages
to provide a comprehensive and seamless search experience.

    SNAP's search engine seeks to deliver relevant search results, emphasizing
high precision and recall in responding to user queries. In addition, due to the
dynamic nature of the Internet, the retrieval of up-to-date information has
become another key factor for the evaluation of Internet search services. To
bring current information to the user, SNAP's producers continually refresh
SNAP's database of Web pages and regularly update the database with new Web
pages.

    SNAP's search engine is able to recognize proper nouns and analyze keyword
proximity to generate more accurate results. For example, a request on Snap.com
for Helen Hunt, with or without quotation marks, will retrieve the information
about the movie and television star and not a large selection of responses about
hunting or other women named "Helen". Another key element of SNAP's technology
is the ability to search using word stems so that tenses and inflections of a
word (such as ask, asks, asked and asking) are considered in the query. Some,
but not all, of SNAP's competitors offer similar functionality in their search
technology.

    For every search, SNAP's innovative response compilation technology allows
the importation of producer-selected data collections into the SNAP system and
gives users ready access to highly relevant results via targeted links to
related URLs. In addition, in April 1999 SNAP entered into an exclusive license
agreement with GlobalBrain.net, Inc. for GlobalBrain.net's proprietary search
technology, which enables the SNAP search engine to rank sites by user
preferences and formulate a search response that reflects the popularity and
freshness of the sites to which the user is referred. The GlobalBrain.net
technology will also enable the customization of search results for different
user groups, by reflecting differences in preferences based on country of
residence, occupation or age. This will allow SNAP to develop new portals
targeted at distinct user segments. In addition to this license, GlobalBrain.net
will furnish SNAP with five additional engineers over three years, to work with
SNAP's research and development team in developing new applications using the
GlobalBrain.net technology.

COMPETITION

    The market for SNAP's products and services continues to develop, is rapidly
evolving and is characterized by an increasing number of market entrants with
competing products and services. A number of companies offer competitive
products and services addressing some of SNAP's target markets, including
America Online, AltaVista, Excite@Home, Infoseek, Lycos and Yahoo!.

    In addition, SNAP is expected to compete with metasearch services that allow
a user to search the databases of several catalogs and directories
simultaneously. SNAP is also expected to compete indirectly with database
vendors that offer information search and retrieval capabilities with their core
database products. In the future, SNAP may encounter competition from providers
of Web browser software, including Netscape and Microsoft, online services and
other providers of other Internet

                                      183
<PAGE>
products and services who elect to incorporate their own search and retrieval
features into their offerings.

    Positive factors relating to SNAP's competitive position in the portal
industry include:

    - SNAP's strategic relationship with NBC and its ability to obtain network
      promotion that many of its competitors do not have;

    - SNAP's innovative SnapLENS-TM- technology, which gives SNAP the ability to
      produce multiple, customized versions of the Snap.com portal rapidly;

    - SNAP's innovative response compilation technology which ranks results
      hierarchically according to relevance; and

    - SNAP's strong reach and user base.

    Negative factors relating to SNAP's competitive position in the portal
industry include:

    - SNAP does not have the size and scale of some of its competitors;

    - SNAP does not have the same sales force or engineering resources as some
      of its competitors; and

    - SNAP does not have a public currency which it can use to readily acquire
      complementary business operations.

    The principal methods of competition in the portal industry relate to the
features and benefits offered to the user, including free services such as
e-mail, portfolio tracking, local news and weather, customized user home pages
and chat services; the relevancy of search results; and the increasing ability
to provide richer user experiences, including through the use of high bandwidth
applications such as audio and video.

RESEARCH AND DEVELOPMENT

    During 1998, SNAP spent approximately $6.3 million on research and
development activities. As of August 31, 1999, SNAP had a research and
development staff of 62 full-time employees located at SNAP's headquarters in
San Francisco, California. In addition, pursuant to its agreement with
GlobalBrain.net, GlobalBrain.net will provide five full-time engineers to SNAP
on a consulting basis to engage in research and development of new search
technologies.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

    SNAP's success depends significantly upon its proprietary technology. The
nature of SNAP's intellectual property protections and the associated risks
faced by SNAP are substantially similar to those discussed above with respect to
NBCi on page 123.

LEGAL PROCEEDINGS

    SNAP filed a complaint against CityAuction, Inc. in March 1999 in connection
with an agreement entered into between SNAP and CityAuction to promote
CityAuction's online auction site in exchange for monetary compensation and
warrants to purchase shares of CityAuction. This matter is presently pending in
Superior Court in San Francisco, California. SNAP is claiming that CityAuction
breached the agreement by refusing to honor SNAP's exercise in February 1999 of
its CityAuction warrants, failing to make a $125,000 payment due to SNAP and
failing to provide SNAP with notice of CityAuction's pending acquisition by
Ticketmaster Online-CitySearch, Inc. SNAP is also claiming that Ticketmaster
induced CityAuction to breach its contractual obligations to SNAP. SNAP is
seeking damages, injunctive and equitable relief of not less than $5 million
from CityAuction, in addition to

                                      184
<PAGE>
damages from Ticketmaster Online-CitySearch Inc. for intentional interference
with the SNAP-CityAuction agreements. CityAuction has filed a cross-complaint
against SNAP seeking rescission of its promotion agreement with SNAP,
restitution of not less than $125,000 and unspecified damages. This matter is in
the discovery stage. An unfavorable outcome in this litigation would deny SNAP
the economic benefit of the claimed payments and stock ownership of CityAuction.

EMPLOYEES

    As of August 31, 1999, SNAP had 289 full-time employees, including 62 in
research and development, 80 in sales and marketing, 108 in product development
and design, and 39 in finance and administration. SNAP's future success will
depend, in part, on its ability to continue to attract, retain and motivate
highly qualified technical and management personnel, for whom competition is
intense. In the past, SNAP has provided incentives such as salary, benefits and
option grants to attract and retain qualified employees. The option grants are
typically subject to vesting over four years. The loss or substantial diversion
of the services of SNAP's officers or other key employees could have a material
adverse effect on SNAP's business, operating results and financial condition.

FACILITIES

    SNAP's headquarters are located in a leased facility in San Francisco,
California, consisting of approximately 96,000 square feet, of which SNAP uses
approximately 71,000 square feet for its operations and subleases the remainder
to unaffiliated third parties. The lease of this facility expires on June 30,
2008. SNAP licenses approximately 1,500 square feet of office space from
Xoom.com in New York, New York for its East Coast sales personnel. This license
expires on the earlier of the closing of the transactions or December 31, 1999.

                  SNAP'S MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    The following discussion should be read in conjunction with the financial
statements and related notes included elsewhere in this proxy
statement/prospectus. The results shown in this proxy statement/ prospectus do
not necessarily indicate the results to be expected in any future periods. This
discussion contains forward-looking statements based on current expectations
that involve risks and uncertainties. Actual results and the timing of events
may differ significantly from those projected in such forward looking statements
due to a number of factors, including those set forth in the section entitled
"Risk Factors" and elsewhere in this proxy statement/prospectus.

OVERVIEW

    SNAP began operations as a division of CNET during December, 1996, and
launched the first version of the service during September, 1997. From inception
through December 31, 1996, SNAP had no sales, and operating activities related
primarily to developing necessary computer infrastructure, recruiting personnel,
and initial planning and development of the Snap.com site. For the period
beginning with the September 1997 launch of the Snap.com site through December
31, 1997, these activities continued with emphasis on growing traffic and reach,
building sales momentum, establishing relationships with advertisers, and
beginning to promote the SNAP brand.

    SNAP generates net revenue from sales of on-line advertising on its Web
site, including lead generation. Total net revenue was $7.3 million and $817,000
for the years ended December 31, 1998 and 1997, respectively. The year-on-year
increase in total net revenue was attributable to higher Web-based advertising
revenue on substantial traffic growth. Cost of net revenues increased similarly
in absolute dollars, reflecting increased sales volume. As SNAP has grown, its
operating expenses in absolute dollars have increased. SNAP expects that the
dollar amount of its operating expenses will continue to increase as a result of
acquisitions, sales and marketing efforts, increased funding of site
development, branding of the SNAP name and expansion of technology, operating
infrastructure and general and administrative staff needed to support its
growth.

    From inception through June 30, 1999, SNAP generated total net revenue of
approximately $23.5 million. Over the last year, quarterly net revenue increased
from approximately $1.1 million to $8.0 million. Since January 1998, the number
of unique users has grown from 685,000 to more than 8.5 million as of July 1999,
according to Media Metrix, an independent Internet audience measurement service.

    As of December 31, 1998 and June 30, 1999, SNAP had an accumulated deficit
of $54.9 million and $100.9 million, respectively. Although SNAP has experienced
rapid growth in net revenue, customers and reach in recent periods, these growth
rates are not sustainable. These growth rates will slow and are not indicative
of future growth rates that SNAP may experience.

    SNAP has not achieved profitability on a quarterly or annual basis to date,
and anticipates that it will incur net losses for the foreseeable future. The
extent of these losses will depend, in part, on the amount and rates of growth
in its net revenue from advertising. SNAP expects its operating expenses to
continue at relatively high levels, especially in the areas of distribution,
sales and marketing, and brand promotion. As a result, SNAP will need to
increase its quarterly net revenue to achieve profitability. SNAP believes that
period-to-period comparisons of its operating results are not meaningful and
that you should not rely upon the results for any period as an indication of
future performance. SNAP's business, results of operations and financial
condition will be materially and adversely affected if:

    - net revenue does not grow at anticipated rates;

    - increases in operating expenses are not offset by commensurate increases
      in net revenue; or

    - SNAP is unable to adjust operating expense levels in light of net revenue.

                                      186
<PAGE>
    SNAP's operating losses might increase in the future, and SNAP cannot
guarantee that it will ever achieve or sustain profitability.

    To date, SNAP has entered into business and technology acquisitions, license
arrangements and strategic alliances in order to increase reach and unique user
base, build its communities, provide community-specific content, generate
additional traffic, increase the number of members and establish additional
sources of net revenue.

    SNAP intends to continue making acquisitions to increase online reach and
membership and to seek additional strategic alliances with content and
distribution partners, including alliances that create co-branded sites through
which SNAP makes its services available. Acquisitions carry numerous risks and
uncertainties, including:

    - difficulties in integrating operations, personnel, technologies, products
      and the information systems of the acquired companies;

    - diversion of management's attention from other business concerns;

    - risks of entering geographic and business markets in which Snap.com has
      little or no prior experience; and

    - potential loss of key employees of acquired entities.

    SNAP cannot guarantee that it will be able to successfully integrate any
businesses, products, technologies or personnel that might be acquired in the
future. A failure to successfully integrate acquired entities or assets could
have a material adverse effect on its business, results of operations and
financial condition. In addition, SNAP cannot guarantee that it will be
successful in identifying and closing transactions with potential acquisition
candidates.

    SNAP has had no international sales to date.

RECENT EVENTS

    In April 1999, SNAP entered into a series of agreements with
GlobalBrain.net, Inc. In aggregate, SNAP provided GlobalBrain with $2 million in
cash and 75,000 membership units, valued at $3 million, in exchange for:

    - a seven-year, exclusive right to utilize the GlobalBrain technology within
      a portal service, with an option to extend an additional five years,

    - non-exclusive rights to utilize the GlobalBrain technology in other SNAP
      products and to sublicense the GlobalBrain technology,

    - a commitment from GlobalBrain to provide a minimum of five dedicated
      GlobalBrain engineers working full time at the discretion of SNAP on
      custom research and development work for three years,

    - a 10% ownership interest in GlobalBrain, and

    - warrants to purchase an additional 41% of GlobalBrain in three separate
      tranches over a five year period.

    SNAP accounted for this transaction as the acquisition of tangible and
intangible assets, which will include allocations of the consideration
surrendered by SNAP relating to purchased technology of approximately $2
million, prepaid development fees of approximately $2 million, and an equity
investment in a private company of approximately $1 million.

    On September 13, 1999, SNAP entered into a strategic alliance with Xoom.com
and ValueVision which is described on page 121.

    NET REVENUE

    Total net revenue for the six months ended June 30, 1999 was $13.4 million,
an increase of approximately $11.4 million over revenues of $2.0 million for the
six months ended June 30, 1998. The increase in net revenue was primarily due to
the substantial traffic growth and an increase in Web-based advertising as
SNAP's higher Web site traffic increased its attractiveness to advertisers.
Traffic growth was attributable principally to promotion on NBC national
television network and to co-branded editions of Snap.com and other distribution
partnerships. One customer, Mail.com, comprised 29% of net revenues for the six
months ended June 30, 1999 in a non-cash transaction using equity as
consideration for services sold by SNAP.

    COST OF NET REVENUE

    Cost of net revenue increased to $5.9 million during the six months ended
June 30, 1999 from $3.9 million for the six months ended June 30, 1998 primarily
as a result of an increase of $1.2 million in content license fees and an
increase of $1.6 million in bandwidth and hosting charges.

    Gross margins increased to 56.2% in the six months ended June 30, 1999 from
a negative 100.9% in the six months ended June 30, 1998 as a result of growth in
net revenue.

    PRODUCT DEVELOPMENT EXPENSES

    Product development expenses consist primarily of payroll and related
expenses for modifications, enhancements and new development operations
personnel and consultants. Product development expenses increased to $5.0
million in the six months ended June 30, 1999 from $2.3 million in the six
months ended June 30, 1998 as a result of hiring additional employees. Product
development costs

                                      188
<PAGE>
decreased as a percentage of total net revenue to 37.5% in the six months ended
June 30, 1999 from 117.6% in the six months ended June 30, 1998 because of the
growth in net revenue.

    SNAP believes product development expenses will continue to increase in the
future as management initiates new product features and makes significant
investments in its Web site to remain competitive.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses consist primarily of payroll and related
expenses for personnel engaged in sales, marketing, publishing and customer
support, as well as advertising, promotional and traffic distribution
expenditures. Sales and marketing expenses increased to $14.6 million in the six
months ended June 30, 1999 from $3.4 million in the six months ended June 30,
1998. The absolute dollar increase from period to period in sales and marketing
expenses was primarily attributable to an increase of $7.9 million in
distribution costs and an increase of $1.9 million in personnel and related
expenses required to implement its sales and marketing strategy. Sales and
marketing costs decreased as a percentage of total net revenue to 109.3% in the
six months ended June 30, 1999 from 172.0% in the six months ended June 30,
1998. SNAP expects to continue hiring additional personnel and to expand SNAP's
branding and marketing campaign. Therefore, SNAP expects marketing and sales
expenses to increase in absolute dollars.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses consist primarily of payroll and related
costs for general corporate functions, including finance, accounting, human
resources, facilities and administration, as well as legal fees, depreciation,
lease expense, insurance, and fees for professional services. General and
administrative expenses increased to $5.7 million in the six months ended June
30, 1999 from $1.4 million in the six months ended June 30, 1998. The absolute
dollar increases from period to period in general and administrative expenses
were primarily due to increases in the number of general and administrative
personnel costs, which increased costs by $2.5 million, and an increase of $1.5
million in facility expenses to support the growth of its operations. General
and administrative expenses decreased as a percentage of total net revenue to
43.0% in the six months ended June 30, 1999 from 71.9% in the six months ended
June 30, 1998. SNAP expects general and administrative expenses to increase in
absolute dollars in future periods as SNAP expands its staff and incurs
additional costs related to its operations.

    AMORTIZATION OF DEFERRED COMPENSATION

    SNAP has recorded deferred stock compensation charges of $8.8 million and $0
during the six months ended June 30, 1999 and 1998, respectively. The deferred
compensation charges account for the difference between the exercise price and
the deemed fair value of some of the unit options SNAP granted to its employees.
SNAP cannot guarantee that it will not accrue additional charges, which could
have a material adverse effect on its business, results of operations and
financial condition.

    Deferred compensation expense reflects the amortization of stock
compensation charges resulting from stock options and restricted stock purchase
agreements. SNAP has recorded deferred compensation expense of $1,766,000 and
$0, during the six months ended June 30, 1999 and 1998, respectively.

    PROMOTION AND ADVERTISING PROVIDED BY NBC

    SNAP has recorded approximately $26.0 million and $0 in promotion and
advertising expense in the six months ended June 30, 1999 and 1998,
respectively. The promotion and advertising services provided have been recorded
as capital contributions based on average cost per thousand impressions value
for commercial air time during the period the services were provided.

                                      189
<PAGE>
    OTHER EXPENSE, NET

    Other expense, net represents the interest income SNAP earned on its cash
and investments, and interest expense arising from the line of credit. SNAP has
recorded approximately $595 and $0 in other expense, net in the six months ended
June 30, 1999 and 1998, respectively. This increase was primarily due to
increased extensions of credit under SNAP's revolving credit facility.

    NET LOSS

    SNAP's net loss for the six month period ended June 30, 1999 was
approximately $46.2 million and it was approximately $9.0 million for the same
period ended June 30, 1998. The $37.2 million increase in the net loss was
principally attributable to non-cash expenses of $26.0 million for promotion and
advertising provided by NBC. The rest of the net loss increase was attributable
to higher distribution costs and increased personnel expenses to support the
growth of the business.

    YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31, 1997

    The following table presents statement of operations data for the periods
indicated as a percentage of total net revenue. Prior to 1997, SNAP had no net
revenue because operations were limited and consisted primarily of start-up
activities.

    NET REVENUES

    SNAP began generating net revenues during 1997. SNAP's total net revenues
increased to $7.3 million for the year ended December 31, 1998 from $817,000 for
the year ended December 31, 1997. The increase in net revenues was primarily due
to an increase in Web-based advertising. SNAP's higher Web site traffic
increased its attractiveness to advertisers, and strategic partnership growth.
E! Online accounted for 18% of net revenues for the year ended December 31,
1997.

    COST OF NET REVENUES

    Cost of net revenues increased to $7.6 million for the year ended December
31, 1998 from $1.5 million for the year ended December 31, 1997 as a result of
an increase of $4.1 million in payroll and related expenses for personnel
engaged in supporting SNAP's product, an increase of $0.9 million in additional
content license fees, and an increase of $1.0 million in bandwidth and hosting
charges.

                                      190
<PAGE>
    Gross deficit improved to a negative 4.2% in the year ended December 31,
1998 from a negative 86.0% in the year ended December 31, 1997, as a result of
growth in net revenue.

    PRODUCT DEVELOPMENT EXPENSES

    Product development expenses consist primarily of payroll and related
expenses for modifications, enhancements and new development operations
personnel and consultants. Product development expenses decreased to $6.3
million in the year ended December 31, 1998 from $9.4 million in the year ended
December 31, 1997. Product development costs decreased as a percentage of total
net revenues to 85.6% in the year ended December 31, 1998 from 1,150.9% in the
year ended December 31, 1997, due to growth in net revenues.

    SNAP believes product development expenses will continue to increase in the
future as management initiates new product features and builds and invests in
new technologies for the Snap.com Web site to remain competitive. Therefore,
SNAP expects that its product development expenses will increase in absolute
dollars for the foreseeable future.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses consist primarily of payroll and related
expenses for personnel engaged in sales, marketing, publishing and customer
support, advertising and promotional expenditures and costs paid to third
parties to distribute page views to the Snap.com Web site (distribution
expenses). Sales and marketing expenses increased to $12.5 million in the year
ended December 31, 1998 from $4.1 million in the year ended December 31, 1997.
The absolute dollar increases from period to period in sales and marketing
expenses were primarily attributable to an increase of $3.0 million in personnel
and related expenses required to implement its sales and marketing strategy, as
well as an increase of $2.1 million in distribution costs. Distribution expenses
increased as a percentage of total net revenues to 29% for the year ended
December 31, 1998 compared to 2% for the year ended December 31, 1997. Sales and
marketing costs decreased as a percentage of total net revenues to 170.6% in the
year ended December 31, 1998, from 500.6% in the year ended December 31, 1997.
SNAP expects to continue hiring additional personnel and to expand SNAP's
branding and marketing campaign. Therefore, SNAP expects marketing and sales
expenses to increase in absolute dollars.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses consist primarily of payroll and related
costs for general corporate functions, including finance, accounting, human
resources, facilities and administration, as well as legal fees, insurance and
fees for professional services. General and administrative expenses increased to
$5.9 million in the year ended December 31, 1998 from $1.4 million in the year
ended December 31, 1997. The absolute dollar increases from period to period in
general and administrative expenses were primarily due to increases in the
number of general and administrative personnel, which increased costs by $1.3
million and an increase of $3.0 million in facility expenses to support the
growth of SNAP's operations. General and administrative expenses decreased as a
percentage of total net revenue to 81.2% in the year ended December 31, 1998
from 167.9% in the year ended December 31, 1997. General and administrative
expenses as a percentage of net revenues have decreased because of the growth in
net revenues. SNAP expects general and administrative expenses to increase in
absolute dollars in future periods as SNAP expands its staff and incurs
additional costs related to its operations.

    AMORTIZATION OF DEFERRED COMPENSATION

    SNAP has recorded deferred stock compensation charges of $2.3 million for
the year ended December 31, 1998. The deferred compensation charges account for
the difference between the exercise price and the deemed fair value of some of
the unit options SNAP granted to its employees.

                                      191
<PAGE>
SNAP cannot guarantee that it will not accrue additional charges, which could
have a material adverse effect on its business, results of operations and
financial condition.

    Deferred compensation expense reflects the amortization of compensation
charges resulting from unit options and restricted unit purchase agreements.
SNAP has recorded deferred compensation expense of $160,000 for the year ended
December 31, 1998.

    PROMOTION AND ADVERTISING PROVIDED BY NBC

    SNAP has recorded approximately $14.1 million in promotion and advertising
expenses provided by NBC for the year ended December 31, 1998. The promotion and
advertising services provided have been recorded as capital contributions based
on the average cost per thousand impressions value for commercial air time
during the period the services were provided.

    INCOME TAXES

    Prior to June 25, 1998 SNAP's taxable losses were included in the
consolidated tax returns of CNET, Inc. SNAP did not receive any benefit from
CNET Inc.'s receipt of such operating losses or research and development
credits.

    Upon the incorporation as a Delaware limited liability company on June 26,
1998, SNAP's net operating losses inured to the benefit of its members.
Accordingly, no provision for income taxes is recognized in the accompanying
financial statements as the net losses generated from SNAP's operations have
been passed through to its members.

    NET LOSS

    SNAP's net loss for the year ended December 31, 1998 was approximately $39.3
million and it was approximately $15.6 million for the same period ended
December 31, 1997. The $23.7 million increase in the net loss was principally
attributable to non-cash expenses of $14.1 million for promotion and advertising
provided by NBC. The rest of the net loss increase was attributable to higher
distribution costs and increased personnel expenses to support the growth of the
business.

QUARTERLY RESULTS OF OPERATIONS

    The following tables present consolidated statements of operations data for
SNAP's five most recent quarters ended June 30, 1999 in dollars and as a

and includes all adjustments (consisting only of normal recurring adjustments)
necessary for fair presentation of the unaudited information for the quarters
presented. You should read this information in conjunction with the consolidated
financial statements, including the notes

                                      192

    SNAP's operating expenses have increased significantly in absolute dollar
amounts in each quarter as SNAP has transitioned from the development stage to
the commercialization of its services and products and expansion of its
business. SNAP expects operating expenses will continue to increase in the
future as SNAP continues to seek to expand its business. To the extent that
these expenses are not accompanied by an increase in net revenue, its business,
results of operations and financial condition could be materially adversely
affected.

    SNAP expects operating results to fluctuate significantly in the future as a
result of a variety of factors, many of which are outside of its control.

                                      193

    As a strategic response to changes in the competitive environment, SNAP
might from time to time make pricing, service or marketing decisions or pursue
business combinations that could have a material adverse effect on its business,
results of operations and financial condition. In order to accelerate the
promotion of the Snap.com brand, SNAP intends to significantly increase its
marketing budget, which could materially and adversely affect its business,
results of operations and financial condition. SNAP expects to experience
seasonality in its business, with user traffic on the Snap.com site potentially
being lower during the summer and year-end vacation and holiday periods when
overall usage of the Web is lower. Additionally, seasonality may significantly
affect SNAP's advertising revenue during the first and third calendar quarters,
as advertisers historically spend less during these periods, and more in the
fourth quarter. Because Web-based commerce and advertising is an emerging
market, additional seasonal and other patterns may develop in the future as the
market matures. Any seasonality is likely to cause quarterly fluctuations in
Snap.com's operating results, and these patterns could have a material adverse
effect on its business, results of operations and financial condition.

    Due to the foregoing factors, SNAP's quarterly net revenue and operating
results are difficult to forecast. Consequently, SNAP believes that period to
period comparisons of its operating results will not necessarily be meaningful
and you should not rely on them as an indication of future performance.

LIQUIDITY AND CAPITAL RESOURCES

    Prior to the commencement of the proposed business combination, SNAP
financed its operations primarily through capital contributions by CNET and NBC,
and a revolving credit facility. On September 14, 1999, the revolving credit
facility was amended to provide for extensions of credit of up to $55,000,000.
Extensions of credit under the facility can be in the form of revolving credit
loans or standby letters of credit. As of December 31, 1998 and June 30, 1999,
SNAP had a total of $13.5 million and $30.1 million, respectively, outstanding
under its revolving credit facility, all of which is due in 1999, but is
expected to be refinanced. The borrowings are classified as long-term on the
face of the balance sheet because SNAP has the ability and intent to extend the
due dates beyond December 31, 1999.

    At December 31, 1998 and June 30, 1999, SNAP had cash and cash equivalents
and short-term investments of approximately $865,000 and $37,000, respectively.

    Net cash used in operating activities for the years ended December 31, 1998
and 1997 was $24.6 million and $14.7 million, respectively. Cash used in
operating activities for the year ended December 31, 1998 was primarily the
result of net losses, partially offset by non-cash promotion and advertising
provided by NBC. Cash used in operating activities for the year ended 1997 was
primarily the result of net losses.

    Net cash used in operating activities for the six months ended June 30, 1999
and 1998 was $10.2 million and $9.4 million, respectively. Cash used in
operating activities for the six months ended June 30, 1999 was primarily the
result of net losses, partially offset by promotion and advertising provided by
NBC. Cash used in operating activities for the six months ended June 30, 1998
was primarily the result of net losses.

    Net cash used in investing activities for the years ended December 31, 1998
and 1997 was $4.5 million and $1.5 million, respectively. Cash used in investing
activities in each period was primarily related to purchases of fixed assets.

    Net cash used in investing activities for the six months ended June 30, 1999
and 1998 was $7.2 million and $1.1 million, respectively. Cash used in investing
activities in each period was primarily related to purchases of fixed assets.

    Net cash provided by financing activities for the years ended December 31,
1998 and 1997 was $30.0 million and $16.2 million, respectively. Cash provided
by financing activities was primarily

                                      194
<PAGE>
attributable to capital contributions. For the year ended December 31, 1998,
cash provided by financing activities also included a cash contribution from NBC
and proceeds from the line of credit.

    Net cash provided by financing activities for the six months ended June 30,
1999 was $16.6 million, and net cash provided by financing activities in the six
months ended June 30, 1998 was $16.4 million. Cash provided by financing
activities in the six months ended June 30, 1999 related to proceeds from the
revolving credit facility. Cash provided by financing activities in the six
months ended June 30, 1998 was attributable to CNET's capital contribution of
$10.5 million and NBC's cash contribution of $5.9 million.

    As of December 31, 1998 and June 30, 1999 SNAP's principal commitments
consisted of obligations outstanding under operating leases.

    SNAP believes that it has the financial resources needed to meet its
presently anticipated business requirements, including capital expenditure and
strategic operating programs, for at least the next 12 months through an
increase of its credit facility and anticipated customer advance payments.

    In the long term, if cash generated by operations is insufficient to satisfy
its liquidity requirements, SNAP may need to sell additional equity or debt
securities or obtain additional credit facilities. The sale of additional equity
or convertible debt securities may result in additional dilution to its
stockholders. SNAP may not be able to raise any such capital on terms acceptable
to SNAP or at all.

DISCLOSURES ABOUT MARKET RISK

    SNAP invests in equity investments in publicly- and privately-held companies
for business and strategic purposes. These investments are segregated as other
long-term assets and are accounted for under the cost method when ownership is
less than 20%. For publicly traded investments, which the Company generally
considers to be available-for-sale securities the Company's policy is to record
such at market value at each reporting date. Any unrealized gains and losses are
recorded in members equity. For non-quoted investments, SNAP's policy is to
regularly review the assumptions underlying the operating performance and cash
flow forecasts in assessing the carrying values. SNAP identifies and records
impairment losses on long-lived assets when events and circumstances indicate
that such assets might be impaired. To date, no such impairment has been
recorded.

YEAR 2000 COMPLIANCE

    SNAP has initiated a comprehensive review of potential issues associated
with the transition to the Year 2000. Executive level sponsorship has been
established and status reports are prepared and distributed weekly. The
appraisal includes:

    - Assessing, remediating and testing software and hardware used to create
      and maintain the Snap.com Web sites,

    - Evaluating software and hardware used within SNAP for internal business
      purposes, as well as updating and testing where appropriate, and

    - Requesting and reviewing preparedness of key partners and suppliers.

    The internal review of software systems supporting the Snap.com Web sites
includes those systems used for site management, network monitoring, quality
assurance and transactions processing. Many of these systems were developed
internally by SNAP when the Year 2000 problem already had some visibility, and
SNAP was largely able to anticipate four digit requirements where years were
considered in software programs. Nevertheless, these systems are being reviewed
line by line to help ensure they will continue to function as intended into the
Year 2000.

    SNAP is also reviewing its computer infrastructure, including network
equipment and servers, for compliance. SNAP does not anticipate material
problems with this equipment, as the current

                                      195
<PAGE>
configuration was installed within the last three years. Similarly, SNAP
purchased most of its servers in 1998 and 1999. With this relatively current
equipment, SNAP does not anticipate material Year 2000 compliance problems, and
SNAP will replace any servers that cannot be updated either in the normal
replacement cycle or on an accelerated basis.

    SNAP has internally standardized all of its IBM-compatible personal
computers on Windows NT 4.0 using reasonably current service packs. SNAP's
vendor for these service packs has advised that these products are Year 2000
compliant. For Apple computers, SNAP has installed the Mac OS Version 8.6 and
has been advised by the vendor that these products are Year 2000 compliant. SNAP
uses multiple software systems for internal business purposes, including
accounting, e-mail, development, human resources, customer service and support
and sales tracking systems. All of these applications have been purchased or
developed within the last three years, and SNAP is in the process of obtaining
verification from key vendors that the product in use is Year 2000 compliant.

    SNAP has made inquiries to vendors of systems that SNAP believes to be
mission critical to its business, as well as key partners, customers and content
providers regarding their Year 2000 readiness. Although SNAP has received and
continues to request various assurances, SNAP has not received affirmative
documentation of Year 2000 compliance from all of these companies and has not
yet completed comprehensive operational testing on its internal systems. SNAP
generally does not have contractual rights against third party providers should
their equipment or software fail due to Year 2000 issues. If these kinds of
issues arise, SNAP may incur unexpected expenses to remedy problems, which could
potentially include purchasing replacement hardware and software and negotiating
arrangements with new partners, customers and content providers. SNAP has not
yet fully appraised the compliance of various third-party suppliers of services
such as telephone companies, long distance carriers, financial institutions and
electric companies, the failure of any one of which could severely disrupt its
ability to carry on its business.

    SNAP anticipates that its review of Year 2000 issues and any remediation
efforts will continue throughout calendar 1999. The costs incurred to date to
remediate Year 2000 issues have not been material. If any Year 2000 issues are
uncovered with respect to systems that support its Web sites or serve internal
functions, SNAP believes that it will be able to resolve these problems without
material difficulty, as replacement systems are generally available on
commercially reasonable terms. SNAP presently estimates that the total remaining
cost of addressing Year 2000 issues will not exceed $300,000. SNAP derived these
estimates using a number of assumptions, including the assumption that SNAP has
already identified its most significant Year 2000 issues. However, these
assumptions may not be accurate, and actual results could differ materially from
those anticipated. In spite of SNAP's review and remediation efforts to date,
the recent development of SNAP's products and services, the recent installation
of SNAP's networking equipment and servers, and the limited activities that
remain to be completed, SNAP is in the process of developing contingency plans
to deal with any foreseeable material Year 2000 issues. These are intended to
mitigate Year 2000 issues but may or may not prevent failures that could
severely disrupt SNAP's ability to carry on its business.

    SNAP's applications operate in complex network environments and directly and
indirectly interact with a number of other hardware and software systems that
are owned and operated by other companies. While SNAP is attempting to verify
that other companies are prepared for the Year 2000, SNAP is unable to predict
with certainty to what extent its business may be affected if its systems or the
systems that operate in conjunction with SNAP experience a material Year 2000
failure. Known or unknown errors or defects that affect the operation of SNAP's
software and systems could result in:

    - a delay or loss of revenue,

    - interruption of services,

    - cancellation of contracts and memberships,

    - diversion of development resources,

                                      196
<PAGE>
    - damage to its reputation, and

    - increased costs, including litigation costs.

    Any of these results could adversely affect SNAP's business, financial
condition and results of operations. SNAP's worst case scenario is that the
Internet fails due to Year 2000 problems, leaving SNAP unable to offer any
services on its Web sites for an extended period of time.

RECENT ACCOUNTING PRONOUNCEMENTS

    The FASB recently issued SFAS No. 133, Accounting for Derivative Instruments
and Hedging Activities. SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including derivative instruments embedded
in other contracts (collectively referred to as derivatives), and for hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. For a derivative not designated as a hedging
instrument, changes in the fair value of the derivative are recognized in
earnings in the period of change. SNAP must adopt SFAS No. 133 by January 1,
2001. Management does not believe the adoption of SFAS No. 133 will have a
material adverse effect on the financial positions or operations of SNAP.

OVERVIEW

    NBC, a wholly owned subsidiary of GE, is one of the leading television
networks in the United States. NBC produces, acquires and distributes a
comprehensive schedule of entertainment, news and sports programming, and
provides network television services to 13 owned stations as well as more than
220 affiliated stations throughout the United States. Through NBC Multimedia,
NBC pursues an array of new media initiatives, including the development of Web
sites related to its principal programming services and strategic relationships
with leading edge interactive technology companies. In addition, NBC produces
and distributes CNBC, a 24-hour cable business and financial news channel, and,
in a joint venture with Microsoft, produces and distributes MSNBC, a 24-hour
cable news channel. NBC also has cable business and financial news channels
offered internationally through a joint venture with Dow Jones.

    Currently, NBC.com, NBC-IN.com and VideoSeeker are operating divisions
within NBC Multimedia, and CNBC.com LLC is a wholly owned subsidiary of NBC.
NBC.com is the online home for NBC's entertainment programming on the Internet,
offering information about NBC television programs and original episodic
programming designed specifically for Internet users, as well as news and
information from MSNBC and NBC-related merchandise. NBC-IN.com is a portal to a
network of local community sites created for more than 100 NBC-owned and
NBC-affiliated television stations in the United States. NBC-IN.com provides
customized advertising and community directory services to complement each
station's news and other local information on its Web site. VideoSeeker is an
on-demand Internet video service featuring television and movie clips, DVD
trailers and related shopping opportunities. Together, NBC.com, NBC-IN.com and
VideoSeeker achieved a reach of 3.8% among home users in July 1999, recording
1.37 million unique visitors, a 11.4% increase over the 1.1 million unique
visitors recorded in June 1998, the first month in which all three services were
operational. CNBC.com, launched on June 21, 1999, is a Web site developed by NBC
in connection with its CNBC cable channel, offering financial information and
analytic tools to assist users in personal financial planning.

NBC.COM

    PRODUCTS AND SERVICES

    Launched by NBC in August 1995, NBC.com is the Internet venue for NBC's
television programming. NBC.com provides information and promotion for NBC
on-air broadcasts as well as original show extensions developed specifically for
Internet users. NBC.com also offers shopping services, as well as bulletin
boards and chat rooms, including chat sessions with NBC on-air talent, through
its cobranded site www.nbc.talkcity.com, operated by Talk City, Inc. NBC.com's
strategy has been to build on the NBC brand to establish itself as a leading
entertainment information Web site.

    NBC.com provides show descriptions, episode updates, actor biographies,
schedule information and program trivia for NBC entertainment programming.
NBC.com gives fans of NBC programming an opportunity to learn more about their
favorite television shows with such features as "backstage tours" and
online-only interviews. NBC.com adapts NBC program content for interactive uses
on NBC.com, such as games and photo galleries. NBC.com maintains direct links to
MSNBC News, MSNBC Sports and CNBC.com. NBC.com also provides direct links to
local news and weather delivered by NBC's local station affiliates through
NBC-IN.com.

    In addition, NBC.com presents customized Internet extensions of NBC
television programming in the form of online "spin-offs" and Internet-only
segments derived from on-air material. NBC links original content from the
enhanced site with the "parent" on-air program, so that characters, story
elements and sketches connect television and Internet media. For example,
through the "Profiler" link on NBC.com, users can participate interactively in a
story extension derived from episodes of the

                                      198
<PAGE>
television program. NBC.com recently created "Virtual Jay," an extension of The
Tonight Show with Jay Leno, which features an animated likeness of Jay Leno
performing original material designed for NBC.com. To date, enhanced show sites
have been created for ten additional NBC television programs including Late
Night with Conan O'Brien and Saturday Night Live.

    NBC.com offers real-time communication in show-related chat rooms hosted by
Talk City through a strategic relationship with NBC, in the form of online
discussions among fans as well as scheduled chat events with on-air celebrities.
In addition, NBC.com offers bulletin board services dedicated to particular
television shows. NBC.com also provides e-commerce functionality for sales of
home video editions of NBC programs and made-for-television movies, NBC-branded
merchandise, and links to online shopping pages not affiliated with NBC.

    NBC.com has been recognized within the Internet industry for its
achievements, winning several awards including Best Story/Script and Best Design
for "Homicide: Second Shift" from Invision, and Promax Awards for on-air
promotions of The Tonight Show and Homicide. NBC.com was a Webby Award finalist
for 1998 Entertainment Site of the Year and an Academy of Interactive Arts &
Sciences finalist for 1998 Entertainment Site of the Year.

    STRATEGIC RELATIONSHIPS

    NBC Multimedia has entered into agreements with USWeb Corporation for
production and hosting services for NBC.com and VideoSeeker.com, and with Talk
City, Inc. for chat services for NBC.com and several of the NBC-IN.com local
station Web sites.

    Under the agreement with USWeb, NBC Multimedia receives Internet production
services as well as Web site hosting, support and technical services from USWeb
for NBC.com and VideoSeeker.com in addition to other NBC Web sites. NBC
Multimedia retains creative and editorial control over all content on its Web
sites hosted by USWeb. NBC Multimedia pays USWeb an annual fee for the services
provided by USWeb. The USWeb agreement has a term of four years expiring in May
2002, and NBC Multimedia has the right to extend the agreement unilaterally for
an additional four-year term at a fixed increase in the annual fee. NBC
Multimedia may terminate the agreement with three months' prior written notice
to USWeb, and beginning in November 1999, USWeb may terminate the agreement with
six months' prior written notice to NBC Multimedia.

    Talk City furnishes all services required to create, maintain and operate
chat services on NBC.com and several of the NBC-IN.com local station Web sites,
in addition to other NBC Web sites. NBC Multimedia receives promotion of the NBC
Web sites on the Talk City Web sites. The term of the Talk City agreement
extends until August 2001, and may be renewed automatically unless either party
notifies the other at least sixty days in advance of the end of the term that it
elects to have the agreement expire. Either party may terminate the agreement at
any time with sixty days' prior written notice.

    REVENUE SOURCES

    NBC.com leverages the power of the NBC television brand to drive traffic to
NBC.com. This provides exposure for NBC.com's advertisers seeking to turn NBC's
television viewers into potential customers for products and services. NBC
believes that its high television viewership and favorable demographics offer a
strong platform to develop NBC.com's ability to attract advertisers. During the
1998-1999 television season, NBC television programming reached approximately
156 million viewers in the United States at least once every week. The NBC.com
Web site address is included with NBC's logo graphic at the end of many
entertainment programs broadcast on the NBC television network in primetime,
although NBC is not obligated to continue to display the NBC.com logo or NBC.com
Web site address in this particular manner. NBC.com has been featured in
promotional spots during NBC

                                      199
<PAGE>
primetime programming as well as The Tonight Show, Saturday Night Live, Late
Night with Conan O'Brien and NBC's "TNBC" block of teen-targeted shows.

    NBC.com generates revenue from the sale of advertising on its site as well
as by providing links to online shopping pages not affiliated with NBC. NBC.com
draws users who represent an attractive demographic group for companies that
advertise and conduct business over the Internet, yielding a wide array of major
advertisers and sponsors including Honda, Johnson & Johnson, Levi Strauss,
Lincoln, Microsoft, Pontiac and VISA. NBC.com also offers advertisers on NBC
television mini-series and special events programming the opportunity to
purchase integrated online sponsorships that feature the on-air sponsor in the
NBC.com area promoting the mini-series or special event.

    NBC.com also generates revenue from development of specialized content for
advertisers. For example, NBC.com developed an area in the NBC.com Web site,
"Jay's Garage", to capitalize on the enthusiasm for cars and driving frequently
expressed on-air during The Tonight Show by host Jay Leno. As a result, NBC.com
has been able to offer automobile advertisers cross-promotional capability by
coordinating television network advertising with sponsorship of "Jay's Garage"
on NBC.com. In addition, NBC.com has provided production capability to
advertisers seeking access to the desirable demographic groups to which NBC
television programming has traditionally appealed. For example, the NBC.com
production team produced an Internet advertising campaign for Levi Strauss that,
although not linked to NBC television programming, increased brand awareness for
NBC.com.

NBC-IN.COM

    PRODUCTS AND SERVICES

    The NBC-IN.com Web site serves as a portal to a network of local news and
information Web sites developed with 104 NBC-owned and NBC-affiliated television
stations throughout the United States. When a user identifies a particular city
of interest, NBC-IN.com enables the user to connect with the Web site of the
local NBC-owned or NBC-affiliated station in that city. On the local station Web
sites connected by NBC-IN.com, users can access news, sports and weather from
MSNBC and, in the case of NBC affiliates, the local station itself. Users can
also access services such as job searching, local advertising for real estate
and automobiles, restaurant reviews and telephone directories customized for the
relevant geographic area. Most of the content appearing on the NBC-IN.com Web
sites is obtained from unaffiliated content providers, often through exclusive
relationships with NBC-IN.com. The NBC-IN.com network of station Web sites
offers advertisers a city-by-city advertising platform tailored to local needs
with on-air and online cross-promotion, anchored by the NBC brand.

    NBC-IN.com was launched in October 1997 with participation by NBC's 13 owned
stations and 30 stations affiliated with NBC. As of July 31, 1999, an additional
61 local NBC-affiliated stations had joined NBC-IN.com, bringing the total
participation to 104 NBC-owned and NBC-affiliated stations throughout the United
States.

    Each station participating in the NBC-IN.com network has significant
discretion to tailor the look and feel of its Web site and the content it
presents to appeal to its local market. NBC-IN.com delivers a portion of each
Web site's content through contractual relationships with national providers of
search services and directories tailored to deliver specialized local
information. Each NBC affiliate station Web site in the NBC-IN.com network has
agreed to include in its Web site all or a portion of the content secured by
NBC-IN.com, depending upon the terms of such affiliate's agreement with
NBC-IN.com. As subsidiaries of NBC, the 13 stations owned by NBC have
historically included all content furnished by NBC-IN.com on their Web sites,
but they are not presently under a written obligation to do so.

    STRATEGIC RELATIONSHIPS

    NBC-IN.com provides a portion of each local site's content through strategic
relationships with Web sites such as Realtor.com, Rent.net, Big Yellow,
Auto-by-Tel and CareerBuilder. These content

                                      200
<PAGE>
providers pay a fee to NBC-IN.com to furnish search or other functionality in a
particular category such as auto and real estate sales, apartment rentals,
telephone directory services and job searching services for the geographic areas
covered by each site throughout the NBC-IN.com site network. For instance, by
clicking on "Cars" on the station Web site, a user is connected to Autobytel.com
and can obtain product reviews and manufacturers' information as well as
purchase, lease or finance a new or used automobile. These strategic
relationships typically have terms of one to three years.

    In addition, NBC-IN.com has entered into an agreement with 24/7 Media to
place sales representatives on site at NBC stations in each of the top twenty
U.S. markets covered by NBC-IN.com. These sales representatives seek to sell
coordinated packages of on-air and online advertising to local advertisers in
their assigned markets in order to develop online advertising sales at each of
the participating stations and capitalize on the cross-promotional opportunities
presented by the local on-air platform. In addition, 24/7 Media provides
training and marketing services to the other stations participating in the
NBC-IN.com network. Under the agreement with 24/7 Media, NBC-IN.com is entitled
to share in revenues from advertisement sales completed by 24/7 sales
representatives. The agreement with 24/7 Media extends to March 11, 2002.

    REVENUE SOURCES

    NBC-IN.com generates revenue from the sale of traditional online advertising
in the form of banners and direct links to non-NBC online shopping pages, and
from content providers seeking access to NBC-IN.com distribution for their
products and services. NBC-IN.com sites attract a wide array of local
advertising categories, including automobiles, real estate sales and rentals,
and job opportunities. NBC-IN.com seeks to leverage the NBC brand to supplement
marketing opportunities that have been tailored for local audiences.

    Jupiter Communications estimates that online advertising revenues will reach
$7.7 billion by 2002, with local advertising revenues representing an increasing
percentage of this total, growing from approximately 10% in 1996 to over 50% in
2002. NBC-IN.com seeks to take advantage of this growth in local online
advertising revenues by offering advertisers an extensive network of Web sites
designed to capture regional differences in consumer demand together with the
opportunity for network and local television cross-promotion. The NBC-IN.com
network enables local advertisers, which traditionally have focused on local
radio and print advertising platforms because of cost, to access the greater
reach and richer media offered by television and the Internet in a more
cost-effective manner. By combining mentions of several advertisers in a single
on-air promotion of a local NBC-IN.com Web site, stations owned by or affiliated
with NBC can provide local advertisers with access to a television audience at a
fraction of the cost for a full advertising spot. In addition, advertisers have
the ability to furnish more extensive information about the products and
services they offer to viewers who visit a station's Web site.

    Moreover, the Internet is changing buying patterns, as consumers
increasingly obtain product information and make purchases via the Internet. For
example, research by J.D. Power & Associates indicates that by 2000, one in five
buyers of new cars will use the Internet in their search, whether to obtain
product reviews and manufacturers' information or to identify potential sellers
and complete a purchase or lease transaction. Department of Commerce statistics
indicate that the cost of online auto sales is approximately 20% of the cost
through traditional dealership sales methods. Consequently, a study by Forrester
Research estimates that spending for online advertising by auto dealers will
exceed $200 million per year by 2000, up from approximately $16 million in 1997.
Through its arrangement for auto sales search and transaction functionality with
Auto-By-Tel, NBC-IN.com seeks to capitalize on this growth in online auto dealer
advertising throughout the NBC-IN.com network of local sites.

    Users are offered several convenient ways to access videos and text,
including by keyword search and genre channels such as "Television", "Movies"
and "Best of the Web". Within each content channel, VideoSeeker promotes new and
noteworthy "hot clips", which account for more than 75% of the videos served on
VideoSeeker. VideoSeeker creates co-branded areas for video partners such as
MSNBC, in which the content provider is given a special area on the site and
advertising and promotion by VideoSeeker in exchange for a royalty-free license
of the video content to VideoSeeker. VideoSeeker also creates specialized areas
of the site to promote categories of content without the need for third-party
branding, such as "Movie Lounge", offering popular movie trailers. Users are
offered the opportunity to register as members, but registration is optional.
Redesigned in October 1998, VideoSeeker delivered over 400,000 clips to users in
July 1999 compared to approximately 80,000 in November 1998.

    STRATEGIC RELATIONSHIPS

    VideoSeeker was formed by NBC in October 1997 through a strategic
relationship with InterVU, Inc., a leading Internet and broadband video hosting
and delivery services company. In coordination with NBC, InterVU built the video
search engine, database, and video-publishing and proprietary traffic analysis
tools used by VideoSeeker. Except for some news video clips, all content is
hosted on InterVU's distributed video network. NBC has a royalty-free
nonexclusive license from InterVU for the use of all software and code required
to operate the VideoSeeker.com search engine and video publishing tools. In
addition, NBC has an agreement with InterVU for the technical maintenance of the
VideoSeeker.com Web site, its video databases and NBC-owned servers.

    REVENUE SOURCES

    VideoSeeker derives revenues from traditional Internet advertisers, offering
banner advertising as well as sponsorships of various areas in the
VideoSeeker.com Web site. VideoSeeker's major customers include Microsoft, DVD
Express and ImpulseBuy Network. In addition, VideoSeeker is a reseller of
InterVU's live events services. VideoSeeker also derives revenue from video
distributors and companies with video libraries. In addition, VideoSeeker is
exploring the insertion of advertisements before and after video clips in order
to deliver advertising similar in format to that carried on television, but to a
more targeted audience.

    VideoSeeker develops Internet user traffic through strategic linking
campaigns with content and commerce partners, homepage promotion on NBC.com and
through the NBC-IN.com network of Web sites. VideoSeeker also develops Internet
user traffic through distribution arrangements such as the inclusion of
VideoSeeker.com in pre-loaded links in Microsoft's Windows Media Player.

GENERAL MATTERS AFFECTING NBC.COM, NBC-IN.COM AND VIDEOSEEKER

    COMPETITION

    In addition to competing with other Web sites for Internet users, NBC.com
competes with traditional media such as television, radio and print. Each of
NBC's television network competitors has one or more Internet sites with content
designed to complement its programming, as do many cable networks and most major
newspapers. Large content providers in other media, including movie and
television studios, cable television providers and print publishers have the
ability to translate their products into online services and cross-promote these
services through the Internet as well as traditional media channels.

    The market for local interactive content and services is also highly
competitive. The NBC-IN.com network of local Web sites competes for users with
local Web site networks such as Excite@Home's City Guides, Lycos City Guides,
America Online's Digital City, Ticketmaster Online-CitySearch, Yahoo! Get Local
and Microsoft Sidewalk. In addition, each Web site in the NBC-IN.com network
competes for advertising revenue with traditional television, print and radio
advertising platforms within its local geographic area.

    The market for broadcast of video via the Internet is immature and highly
fragmented, and thus highly competitive. Such competition is expected to
intensify as the number of video-enabled users and digital distribution outlets
expands. VideoSeeker faces significant competition in the delivery of video
content via the Internet from general and niche video aggregation services such
as Broadcast.com, Inc., CNN VideoSelect, RealNetworks, FoxNews and FasTV. In
addition, search engines and Internet service providers such as Yahoo!, America
Online, and Excite@Home offer users access to video content via the Internet,
including through broadband platforms. Moreover, media companies such as Disney,
Warner Brothers, Sony, Viacom and Fox, which possess both significant content
libraries and strong brand recognition, may devote significant resources to
developing competitive services for the delivery of owned and acquired video
content.

    Web sites such as NBC.com, NBC-IN.com and VideoSeeker principally seek to
compete for users by providing a depth and breadth of innovative content, and
for advertisers by offering significant numbers of users in valuable demographic
categories. NBC has been conducting Web site operations since its launch of
NBC.com in August 1995, and NBC's television programming has been a principal
source of content for its sites during this period. While NBC historically has
been successful in attracting on-air advertising by offering television
viewership attractive to its advertisers, competitors of the NBC contributed
Internet businesses have demonstrated greater reach among Internet users and
many have been more successful in attracting advertisers to their Web sites.

    The negative factors relating to the competitive position of the NBC
contributed Internet assets include:

    - Significant dependence upon NBC television programming to furnish Web site
      content;

    - The existence of media competitors with substantial resources to devote to
      interactive media initiatives, as well as smaller cutting edge content
      providers;

    - The historically limited combined reach of the NBC contributed Internet
      assets; and

    - The absence of a publicly traded, Internet-focused currency with which to
      finance complementary acquisitions.

    INTELLECTUAL PROPERTY

    The financial success of NBC.com, the NBC-IN.com network of Web sites and
VideoSeeker depends in part on the protection of the intellectual property
rights related to their operation. The nature of the intellectual property
protections and the associated risks faced by NBC.com, NBC-IN.com

                                      203
<PAGE>
and VideoSeeker.com are substantially similar to those discussed above with
respect to NBCi on page 123.

    LEGAL PROCEEDINGS

    From time to time NBC has been subject to legal proceedings and claims in
the ordinary course of its business, including claims of alleged infringement of
third-party trademarks and other intellectual property rights. By distributing
content over the Internet, the NBC contributed Internet assets expose NBC to
potential liability for claims based on the nature and content of the materials
distributed, including claims for defamation, negligence or copyright, patent or
trademark infringement. Such claims have been litigated successfully against
Internet companies, but even if unsuccessful may result in the expenditure of
significant financial and managerial resources.

    EMPLOYEES

    As of August 31, 1999, NBC had 11 full-time employees devoted to operations
relating to the operation of NBC.com, NBC-IN.com and VideoSeeker. None of those
employees is subject to a collective bargaining agreement and NBC believes that
its relations with such employees are good.

    FACILITIES

    NBC's operations relating to NBC.com, NBC-IN.com and VideoSeeker are located
in facilities beneficially owned by NBC in New York, New York through existing
synthetic lease arrangements with the New York Industrial Development Agency and
NBC Trust No. 1996A, and in facilities owned in fee by NBC located in Burbank,
California.

CNBC.COM

    Upon the closing of the proposed transaction, NBC will contribute a 10%
equity interest in CNBC.com LLC, a newly formed limited liability company which
operates, maintains and markets the CNBC.com Web site. The CNBC.com Web site was
launched on June 21, 1999, and has only a limited operating history as a beta
test Web site. CNBC.com LLC has no operating history upon which its future
prospects may be evaluated. Consequently its prospects must be considered in
light of the substantial risks and expenses associated with the introduction of
a new Web site such as CNBC.com and the highly competitive market for delivery
of financial information and analytic tools via the Internet.

    PRODUCTS AND SERVICES

    CNBC.com is an Internet financial information service developed by NBC in
connection with its CNBC cable television channel, one of the leading business
and financial news channels on television. According to data provided by Nielsen
Media Research, CNBC is distributed to over 70 million homes, and was watched at
least once each week by more than 14.3 million adults 18 or older during August
1999, the last month for which weekly data is available. CNBC.com seeks to
leverage the CNBC cable brand to become the leading Internet provider of
comprehensive, real-time financial information and analytic tools. CNBC.com also
offers commentary and analysis from CNBC.com editorial personnel, personal
financial portfolio tracking, and community features together with links to
selected business news via MSNBC to satisfy the full array of its users'
financial information needs. CNBC.com plans to feature subscription services and
finance-related e-commerce services. CNBC on-air personalities are featured on
different areas of the Web site, to contribute to the identification of CNBC.com
with the CNBC cable brand.

    CNBC.com provides stock quotes from all major U.S. stock markets. Users can
receive real-time quotes, presented without a material time delay from their
release by the markets, by registering with CNBC.com. On stock quote pages,
users can link to other valuable information about a particular

                                      204
<PAGE>
company, including summaries of SEC filings and annual reports, summaries of
analysts' information and a variety of fundamental and technical information
about its stock. CNBC.com also plans to offer third party financial data and
other services such as company profiles, company earnings estimates and company
and industry research reports. In addition, CNBC.com provides an array of data
that fluctuates throughout the business day, including domestic and
international market indices, industry indices and currency exchange rates. In
order to take advantage of CNBC.com's real-time stock quotes and portfolio
tracking services, users must complete registration forms and provide
demographic information about themselves, enabling CNBC.com to target
advertising opportunities within the Web site.

    CNBC.com offers users a variety of analytic tools to assess stock trends and
assist in personal financial planning. Through CNBC.com's "Tools" bar, users are
directed to a page with several stories describing, for example, different
methods for identifying stock investment opportunities. Through links in these
stories or via buttons on the "Tools" front page, users can proceed to an array
of search engines and pre-built algorithms that identify publicly-traded
securities that meet criteria selected by the user. CNBC.com plans to offer
additional financial planning tools in such areas as home mortgage and
retirement planning.

    While substantially all of the programming available on CNBC.com is
currently free of charge, CNBC.com plans to offer subscription services in the
future. CNBC.com does not intend to derive a material amount of revenue from
these services.

    CNBC.com offers live chat events with on-air and online guests and CNBC
personalities. CNBC.com also plans to offer a bulletin board service where users
can discuss market trends, investments and other information of interest.
Additionally, because CNBC.com intends to integrate related market data and
charts offered throughout its service, NBC believes that providing a place for
its television viewers and Internet audience to meet and share ideas with
financial commentators and industry experts will help increase brand awareness
for CNBC.com and will motivate users to return to CNBC.com.

    REVENUE STRATEGY

    CNBC.com presently has no revenues. NBC expects CNBC.com to derive a
substantial majority of its future revenues from sales of advertising, including
sponsorship arrangements and advertisements coordinated with on-air advertising
on the CNBC cable channel. There can be no assurance that the current strategy
for CNBC.com to generate revenue will be successful, or that CNBC.com will
receive revenues from advertising or other sources.

    CNBC.com is focused on providing advertisers with a large, demographically
desirable audience. CNBC.com's relationship with CNBC will give CNBC.com access
to a national cable audience to help build traffic at CNBC.com. CNBC reaches
over 70 million cable homes throughout the United States. The CNBC.com logo and
Web site address are expected to be identified during CNBC television
broadcasts, although CNBC will not be obligated to do so. This increased
visibility among existing and anticipated Internet users is intended to position
CNBC.com to compete for Internet advertisers, including e-commerce services, by
offering cross-promotional opportunities with the CNBC cable television
platform.

    In order to attract new users and grow a loyal audience that appeals to a
broad range of advertisers and business partners, CNBC.com intends to continue
to develop compelling content for its users. Advertisements are expected to be
displayed throughout the site, when a user enters the service, reviews an
analysis or accesses a quote or portfolio. In addition, by continuing to offer
community services such as chat rooms and bulletin boards, CNBC.com will offer
members the ability to gravitate towards others who share their specific
interests, encouraging the creation of niche user groups which can be targeted
with relevant marketing campaigns and transaction opportunities. CNBC.com
intends to pursue e-commerce opportunities aggressively through strategic and
marketing relationships with a

                                      205
<PAGE>
variety of financial services companies. With focused content and a targeted
audience, CNBC.com will seek strategic relationships with financial services
companies such as marketers of credit cards, consumer and home loan companies
and insurance providers.

    CNBC.com's community building efforts are focused on strengthening audience
loyalty, increasing page views and providing opportunities for premium
sponsorships, such as moderated chat events. As CNBC.com gathers more
information about the interests of its community members, it intends to offer
targeted advertising in specialized community forums and pursue e-commerce
services with the goal of entering into revenue sharing relationships based on
transactions derived from community members.

    RELATIONSHIP WITH NBCI

    Upon the closing of the proposed transactions. NBC will own 90% of CNBC.com
LLC. The equity interest contributed to NBCi will be subject to restrictions
against transfer by NBCi. The equity interest will have no governance rights
with respect to CNBC.com LLC other than the right to vote such equity interest
with respect to matters required to be approved by a vote of equity holders of
CNBC.com LLC under the limited liability company agreement of CNBC.com LLC.
However, as the holder of the remaining 90% interest in CNBC.com LLC, NBC will
have effective control over any matters subject to approval by a vote of equity
holders. In addition, in the event that NBC assigns or transfers more than 50%
of the equity interests in CNBC.com LLC to a third party, NBC may compel NBCi to
transfer NBC's equity interest in CNBC.com LLC as well, and NBCi in some
circumstances may compel NBC to include NBCi's equity interest in such a
transfer by NBC.

    In connection with the transactions, CNBC and NBCi intend to enter into a
carriage agreement pursuant to which CNBC will provide specific services and
some content from CNBC.com to NBCi.

    INFRASTRUCTURE, OPERATIONS AND TECHNOLOGY

    CNBC.com is hosted at and all of its network operations are controlled from
the facilities of Telescan, Inc. in Houston, Texas.

    COMPETITION

    The market for delivery of financial information and analytic tools via the
Internet is relatively new, intensely competitive and rapidly evolving. The
number of sites on the Internet offering financial information similar to that
of CNBC.com has expanded and NBC expects that competition will continue to
intensify. Within this segment of Internet content, CNBC.com competes for users'
attention with traditional media targeted to business, finance and investing
needs such as television networks and cable channels as well as THE WALL STREET
JOURNAL and BARRON'S. Many of these entities have strong brand recognition
within their medium and have recently developed Web sites. In addition, both
general purpose consumer online services, such as America Online and Microsoft
Network, and online services targeted to business, finance and investing needs,
such as TheStreet.com, Marketwatch.com and Motley Fool, provide financial and
business-related content and services over the Internet. Moreover, a number of
search and retrieval services, such as Excite@Home, Infoseek, Lycos and Yahoo!,
offer stock quotes, financial news and other programming and links to other Web
sites related to business and finance. NBC anticipates that the number of direct
and indirect competitors of CNBC.com will increase in the future. Moreover,
because of NBC's relationships with its existing strategic partners including
Microsoft and Dow Jones, CNBC.com LLC, as an affiliate of NBC, will be
restricted in significant respects in its ability to provide specific types of
content and services, including business news, on CNBC.com. These restrictions
may limit CNBC.com's ability to compete by limiting the services it can offer to
meet users' needs.

    In addition, the Internet competes with traditional advertising media for a
share of advertisers' total advertising budgets. Competition for users'
attention and spending ability may result in price reductions for advertising,
reduced margins, operating losses or inability to obtain market share, any of

                                      206
<PAGE>
which would materially adversely affect CNBC.com's prospects. Many existing
competitors of CNBC.com, as well as a number of potential new competitors, have
longer operating histories in the Internet, greater name recognition, larger
customer bases and higher amounts of user traffic than CNBC.com. Such
competitors may be able to undertake more extensive marketing campaigns, adopt
more aggressive pricing policies, and consequently make more attractive offers
to potential distribution partners, advertisers and content providers than
CNBC.com. As a result, there can be no assurance that CNBC.com will be able to
compete successfully against current or future competitors or that competition
will not have a material adverse effect on CNBC.com's business, results of
operations and financial condition.

    LEGAL PROCEEDINGS

    CNBC.com LLC is a newly formed limited liability company and is not subject
to any pending or threatened litigation.

    EMPLOYEES

    As of August 31, 1999, CNBC.com had 34 full-time employees of NBC devoted to
its operations, including one in sales and marketing, 22 in operations and
product development and 11 in finance and administration. The future success of
CNBC.com will depend, in part, on its ability to continue to attract, retain and
motivate highly qualified technical, creative and management personnel.
CNBC.com's employees are not covered by any collective bargaining agreement.

    FACILITIES

    CNBC.com LLC conducts its operations principally from CNBC's leased
facilities in Ft. Lee, New Jersey.

  NBC MULTIMEDIA DIVISION'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

    The following discussion should be read in conjunction with the combined
financial statements of NBC Multimedia Division, which consists of NBC.com,
NBC-IN.com and VideoSeeker, and related notes included elsewhere in this proxy
statement/prospectus. The results shown in this proxy statement/ prospectus do
not necessarily indicate the results to be expected in any future periods. This
discussion contains forward-looking statements based on current expectations
that involve risks and uncertainties. Actual results and the timing of events
may differ significantly from those projected in such forward looking statements
due to a number of factors, including those set forth in the section entitled
"Risk Factors" and elsewhere in this proxy statement/prospectus.

OVERVIEW

    The historical combined financial statements of the NBC Multimedia Division,
included elsewhere in this prospectus and discussed below, reflect various
assumptions relating to the allocation of corporate general and administrative
expenses incurred on a consolidated basis by NBC. These assumptions may not be
indicative of the financial results that would have resulted if the NBC
Multimedia Division had been an independent company during the periods
presented. The cash flows reflected as parent company's investment and net
advances in the statements of cash flows represent net contributions from NBC to
finance the NBC Multimedia Division's operations. These cash flows may not be
indicative of the cash flows that would have resulted had the NBC Multimedia
Division been operating as a separate stand-alone company during the periods
presented.

    In view of the rapidly changing nature of the businesses associated with the
NBC Multimedia Division, the limited operating history and the seasonality of
the businesses, NBC believes that comparisons of the NBC Multimedia Division's
operating results for any period with those of the preceding period are not
necessarily meaningful and should not be relied upon as an indication of future
performance. The revenue and operating results of the NBC Multimedia Division
may vary from quarter to quarter due to a number of factors, some of which are
beyond the control of NBC.

    The NBC Multimedia Division derives revenue from the sale of banner
advertisements under short-term contracts as well as sponsorship contracts for
fees related to the design, coordination and integration of the customers'
content and links to its Web sites. The NBC Multimedia Division prices such
advertising and sponsorships based on a variety of factors, including whether
the advertisement is targeted to a specific category of users or runs across the
entire Web site, and whether the sponsorship is exclusive or non-exclusive.
Banner advertisements are generally sold based on a cost per thousand.
Sponsorships are generally sold on a fixed price basis over a defined time
period and the revenue is recognized ratably over the agreement.

    The NBC Multimedia Division also derives revenue from license fees from
various service providers who pay a fee to furnish content, e-commerce or
services in a particular category of its Web sites such as chat, search, travel,
classifieds and yellow pages. These fees are payable in either cash or equity
instruments and are recognized ratably over the term of the license period.

    Finally, the NBC Multimedia Division derives revenue through the receipt of
cash and equity instruments from third parties under outsourcing agreements. NBC
Multimedia has entered into the following outsourcing agreements on behalf of
the NBC Multimedia Division:

    - a two-year strategic alliance agreement with InterVU, Inc. whereby InterVU
      is the exclusive provider, subject to specified limitations, of technology
      and services for VideoSeeker;


    - a four-year strategic alliance with USWeb whereby USWeb performs
      production and hosting services for the NBC interactive properties
      including the NBC Multimedia Division; and


                                      208
<PAGE>
    - a three-year agreement under which 24/7 Media, Inc. will sell advertising
      on participating NBC-owned and NBC-affiliated television stations and
      their associated Web sites.

    It is unlikely the NBC Multimedia Division will be able to continue to
receive cash and equity instruments if and when it enters into future
outsourcing agreements.

    When the measurement date is fixed for equity instruments received under
service provider agreements, and there is a sufficient disincentive to breach
the contract, the NBC Multimedia Division records the receipt of the equity
instruments and corresponding deferred revenue. When equity instruments are
contingent upon the achievement of specific targets, each business records the
benefit of the equity instruments at the time the targets are achieved at the
then fair market value of the equity instruments. Such amounts are amortized
ratably to revenue over the length of the contract commencing on the measurement
date.

    Equity instruments are transferred to NBC upon the measurement date and are
charged to parent company's investment and net advances. Changes in value
subsequent to the measurement date are not reflected in the combined financial
statements of the NBC Multimedia Division. In accordance with the terms of the
contribution agreement, equity instruments received from service provider
agreements will not be contributed by NBC to NBCi.

RESULTS OF OPERATIONS

    SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO THE SIX MONTHS ENDED JUNE 30,
     1998

    REVENUE

    Total revenue for the six months ended June 30, 1999 was $8.9 million, an
increase of $4.7 million over revenue of $4.2 million for the six months ended
June 30, 1998. Included in revenue is revenue from equity instruments received
of $6.3 million and $1.8 million during the six months ended June 30, 1999 and
1998, respectively. The increase in revenue was primarily due to an increase in
license fee revenue from additional content and service providers and an
increase in equity instruments received as part of entering into outsourcing
agreements.

    ADVERTISING AND SPONSORSHIP REVENUE

    Advertising and sponsorship revenue decreased to $1.6 million in the six
months ended June 30, 1999 from $1.8 million in the six months ended June 30,
1998. The decrease in advertising and sponsorship revenue is primarily a result
of reallocating resources to assist in the development of new media initiatives
within NBC such as the re-launch of CNBC.com. In addition, the NBC Multimedia
Division's sales force was integrated into the SNAP sales force to create one
combined sales team during July 1999.

    LICENSE FEE REVENUE

    License fee revenue increased to $2.7 million in the six months ended June
30, 1999 from $460,000 in the six months ended June 30, 1998. Included in
license fee revenue is revenue from equity instruments received of $2.2 million
and $263,000 in the six months ended June 30, 1999 and 1998, respectively. The
increase in license fee revenue is primarily a result of an increase in the
number of service provider agreements for placement of content and/or services
on the NBC Multimedia Division's Web sites and the increase in market value of
the equity instruments received under these agreements on the applicable
measurement date.

    Revenue attributable to the equity instruments is likely to decrease as a
percentage of total revenue due to the fact that NBC Multimedia has entered into
exclusive agreements for many of the services offered on the NBC Multimedia
Division's Web sites, an increase in the NBC Multimedia

                                      209
<PAGE>
Division's focus on receiving cash as opposed to equity instruments for the
license arrangements and the uncertainty and volatility of the Internet stock
market.

    OTHER REVENUE

    Other revenue increased to $4.6 million in the six months ended June 30,
1999 from $2.0 million in the six months ended June 30, 1998. Included in other
revenue is revenue from equity instruments received of $4.1 million and $1.5
million in the six months ended June 30, 1999 and 1998, respectively. The
increase in other revenue is due to an increase in the number of equity
instruments received under outsourcing agreements, and the increase in market
value of those equity instruments on the applicable measurement date.

    Other revenue is likely to decline significantly in the future as the focus
of the NBC Multimedia Division is to grow traffic and, therefore, advertising,
sponsorship and license-fee revenue. It is unlikely the NBC Multimedia Division
will be able to continue to receive cash and equity instruments with respect to
future third party outsourcing agreements. Furthermore, it is not possible to
predict future values of such equity instruments when received.

    COST OF REVENUE

    Cost of revenue consists primarily of costs incurred to create and produce
the content of the NBC Multimedia Division's Web sites as well as the technical
hosting and bandwidth charges associated with transmitting such content over the
Internet. Cost of revenue increased to $2.8 million in the six months ended June
30, 1999 from $2.5 million in the six months ended June 30, 1998. The increase
was primarily the result of the costs to produce VideoSeeker.com, which was not
launched until May of 1998. Although, during 1998, the NBC Multimedia Division
outsourced some of its Web production functions to USWeb, this did not have a
material impact on cost of revenue.

    Cost of revenue is likely to increase due to an increase in the quality and
quantity of the content on NBC.com and incremental expenditures to license third
party video content for Videoseeker.com and third party local content for
NBC-IN.com.

    OPERATING AND DEVELOPMENT EXPENSES

    Operating and development expenses consist primarily of payroll and related
costs for network operations personnel and technology consultants. Operating and
development expenses decreased to $297,000 in the six months ended June 30, 1999
from $563,000 in the six months ended June 30, 1998. The decrease was primarily
the result of a reallocation of resources to assist in the development of new
media initiatives within NBC such as the re-launch of CNBC.com. These costs are
likely to increase during the remainder of 1999, but are expected to remain at
or below levels of 1998.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses consist primarily of payroll and related costs
for personnel engaged in sales, marketing and customer support as well as
advertising and promotional expenditures. Sales and marketing expenses decreased
to $747,000 in the six months ended June 30, 1999 from $1.8 million in the six
months ended June 30, 1998. Included in sales and marketing expenses are noncash
charges related to advertising provided by NBC of $0 and $792,000 during the six
months ended June 30, 1999 and 1998, respectively, which have been recorded
based on average values for commercial air time sold by NBC during the period
the services were provided. The decrease was primarily the result of the
decrease in advertising provided by NBC of $792,000 and the remaining decrease
is attributable to third party advertising and promotional expenditures. These
costs are likely to increase during the remainder of 1999, but are expected to
remain at or below levels of 1998.

                                      210
<PAGE>
    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses consist primarily of payroll and related
costs for general corporate purposes, including finance, accounting, human
resources, legal and facilities as well as insurance and other administrative
expenditures. General and administrative expenses decreased to $1.4 million in
the six months ended June 30, 1999 from $2.1 million in the six months ended
June 30, 1998. Included in general and administrative expenses are costs related
to the allocation of corporate general and administrative expenses incurred on a
consolidated basis by NBC of $973,000 and $967,000 during the six months ended
June 30, 1999 and 1998, respectively. The decrease was primarily the result of
reallocating resources to assist in the development of new media initiatives
within NBC such as the re-launch of CNBC.com. These costs are likely to increase
during the remainder of 1999, but are expected to remain at or below levels of
1998.

    NET INCOME

    Net income increased to $3.6 million in the six months ended June 30, 1999
from a net loss of $2.8 million in the six months ended June 30, 1998. The
increase in net income is primarily a result of an increase in equity and
warrants received as part of entering into licensing and outsourcing agreements.

    YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR ENDED DECEMBER 31, 1997

    REVENUE

    Total revenue for the year ended December 31, 1998 was $11.6 million, an
increase of $8.4 million over revenue of $3.2 million for the year ended
December 31, 1997. Included in revenue is revenue from equity instruments
received of $5.1 million and $33,000 during the year ended December 31, 1998 and
1997, respectively. The increase in revenue was primarily due to an increase in
the number of advertising and sponsorship packages sold, an increase in license
fee revenue from service providers and an increase in equity instruments
received as part of entering into outsourcing agreements. No single customer
exceeded 10% of NBC Multimedia Division's advertising, sponsorship and license
fee revenue for the year ended December 31, 1998. Two customers accounted for
42% of its accounts receivable at December 31, 1998. Three customers exceeded
10% of revenue for the year ended December 31, 1997. Three customers accounted
for approximately 74% of accounts receivable at December 31, 1997.

    ADVERTISING AND SPONSORSHIP REVENUE

    Advertising and sponsorship revenue increased to $4.1 million in the year
ended December 31, 1998 from $2.5 million in the year ended December 31, 1997.
The increase in advertising and sponsorship revenue is primarily a result of an
increase in site traffic at NBC.com and NBC-IN.com as well as selling higher
priced specialized content sponsorship packages such as "Jay's Garage," "Back to
School" and TNBC. In addition, during 1998, NBC.com began offering advertisers
on NBC television mini-series and special events programming the opportunity to
purchase integrated online sponsorships that feature the on-air sponsor in the
NBC.com area promoting the mini-series or special event.

    LICENSE FEE REVENUE

    License fee revenue increased to $2.8 million in the year ended December 31,
1998 from $690,000 in the year ended December 31, 1997. Included in license fee
revenue is revenue from equity instruments received of $1.4 million and $33,000
in the years ended December 31, 1998 and 1997, respectively. The increase in
license fee revenue is primarily a result of an increase in the number of
companies paying fees for prominent placement of their content or services on
the NBC Multimedia Division's Web sites. The increase in these fees is
attributable to both the increase in the number of

                                      211
<PAGE>
equity instruments received and in the market value of those equity instruments
on the applicable measurement date.

    OTHER REVENUE

    Other revenue increased to $4.7 million in the year ended December 31, 1998
from $0 in the year ended December 31, 1997. Included in other revenue is
revenue from equity instruments received of $3.7 million and $0 in the years
ended December 31, 1998 and 1997, respectively. The increase in other revenue is
due to an increase in the number of equity instruments received as part of
entering into outsourcing agreements. No such agreements were entered into prior
to 1998.

    COST OF REVENUE

    Cost of revenue increased to $5.2 million in the year ended December 31,
1998 from $4.4 million in the year ended December 31, 1997. The increase was
primarily the result of the costs incurred in creating additional specialized
content during 1998 and new on-line shows and events such as Saturday Night
Live, Late Night with Conan O'Brien and the Emmy broadcast. During 1998, the NBC
Multimedia Division outsourced some of its Web production functions to USWeb,
however, this did not have a material impact on cost of revenue.

    OPERATING AND DEVELOPMENT EXPENSES

    Operating and development expenses increased to $938,000 in the year ended
December 31, 1998 from $677,000 in the year ended December 31, 1997. The
increase was primarily the result of an increase in technical personnel to
support the growth of the NBC Multimedia Division resulting from the launch of
NBC-IN.com and VideoSeeker.com.

    SALES AND MARKETING EXPENSES

    Sales and marketing expenses increased to $4.0 million in the year ended
December 31, 1998 from $2.4 million in the year ended December 31, 1997.
Included in sales and marketing expenses are noncash charges related to
advertising provided by NBC of $2.0 million and $0 during the years ended
December 31, 1998 and 1997, respectively, which have been recorded based on
average values for commercial air time sold by NBC during the period the
services were provided. The increase was primarily the result of focusing on
building brand awareness and site traffic by utilizing the power of the NBC
television audience while reducing third party advertising and promotional
expenditures. The NBC Multimedia Division began airing spots on the NBC
television network late in the first quarter of 1998.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses increased to $4.5 million in year ended
December 31, 1998 from $3.5 million in the year ended December 31, 1997.
Included in general and administrative expenses are costs related to the
allocation of corporate general and administrative expenses incurred on a
consolidated basis by NBC of $1.9 million and $1.6 million during the years
ended December 31, 1998 and 1997, respectively. The increase was primarily the
result of an increase in management and administrative personnel to support the
overall growth of the NBC Multimedia Division as well as the launch of
NBC-IN.com and VideoSeeker.com.

    INCOME TAXES

    The NBC Multimedia Division has generated net losses for all periods through
December 31, 1998, and has no net income tax expense in any period on a
stand-alone basis.

                                      212
<PAGE>
    NET LOSS

    Net loss decreased to $3.1 million in the year ended December 31, 1998 from
a net loss of $7.7 million in the year ended December 31, 1997. The decrease in
net loss is primarily a result of an increase in equity instruments received as
part of entering into licensing and outsourcing agreements.

LIQUIDITY AND CAPITAL RESOURCES

    Since inception, the NBC Multimedia Division has financed working capital
through advances received from NBC. The NBC Multimedia Division participates in
NBC's cash management system. All cash generated from and cash required to
support the NBC Multimedia Division's operations are deposited and received
through NBC's corporate operating cash accounts. As a result, there are no
separate bank accounts for the NBC Multimedia Division. Accordingly, the amounts
represented by the caption "Advances received from parent, net" in the NBC
Multimedia Division's combined statement of cash flows represent the net effect
of all cash transactions between the NBC Multimedia Division and NBC.

    Net cash used in operating activities for the years ended December 31, 1998
and 1997 was $5.9 million and $7.0 million, respectively. Cash used in operating
activities for the year ended December 31, 1997 was primarily the result of net
losses, partially offset by depreciation and amortization, loss on disposal of
assets and net changes in operating assets and liabilities. Cash used in
operating activities for the year ended December 31, 1998 was primarily the
result of net losses increased by noncash revenue related to partner agreements
and decreased by noncash expenses related to advertising provided by NBC,
partially offset by depreciation and amortization and loss on disposal of
assets.

    Net cash used in operating activities for the six months ended June 30, 1999
and 1998 was $2.6 million and $2.9 million, respectively. Cash used in operating
activities for the six months ended June 30, 1999 was primarily the result of
net income decreased by noncash revenue related to partner agreements. Cash used
in operating activities for the six months ended June 30, 1998 was primarily the
result of net losses, increased by noncash revenue related to partner
agreements.

    Net cash used in investing activities for the years ended December 31, 1998
and 1997 was $103,000 and $152,000, respectively, and was related to purchases
of property and equipment.

    Net cash used in investing activities for the six months ended June 30, 1999
and 1998 was $0 and $99,000, respectively, and was related to purchases of
property and equipment.

    Net cash provided by financing activities for the years ended December 31,
1998 and 1997 was $6.0 million and $7.1 million, respectively, and consisted of
net proceeds from advances from NBC.

    Net cash provided by financing activities for the six months ended June 30,
1999 and 1998 was $2.6 million and $3.0 million, respectively, and consisted of
net proceeds from advances from NBC.

    NBC Multimedia Division is an operating division of NBC Multimedia Inc., a
wholly-owned subsidiary of NBC. To date, NBC Multimedia Division has been funded
by NBC and will continue to be funded by NBC for at least the next twelve months
so long as NBC Multimedia Division remains a consolidated entity of NBC and GE.

YEAR 2000 COMPLIANCE

    STATE OF READINESS

    GE and NBC, including the NBC Multimedia Division, are engaged in an
aggressive and comprehensive effort to identify and address Year 2000 issues.
NBC's program, including the NBC Multimedia Division, focuses on the possible
effects of the Year 2000 problem in four areas:

    - Facilities--including building systems, embedded technology and other
      systems;

                                      213
<PAGE>
    - Information technology systems--including servers and serving
      technologies;

    - Suppliers--including third-party vendors; and

    - Products--including in-house developed software.

    Within each of these areas, NBC's approach, including the NBC Multimedia
Division, encompasses:

    - Measurement--taking inventories of devices and suppliers that may be
      affected by Year 2000 issues and are critical to its business;

    - Analysis--testing to determine how the Year 2000 issue might manifest
      itself and developing project plans to address any Year 2000 issues;

    - Improvement--executing project plans and remediating or replacing the
      affected devices, including preparing alternates for suppliers who have
      not responded to our requests; and

    - Control--taking steps to ensure Year 2000 solutions remain intact
      investing the preparation of business continuity plans.

    NBC, as well as GE as a whole, is devoting substantial resources to the Year
2000 effort. At the GE level, the Year 2000 Project is directed by the chief
information officer, who is a senior vice president of GE. The chief information
officer and his staff set goals for the Year 2000 program, monitor
implementation by the various businesses within GE, and facilitate the sharing
of best practices among such businesses. Other key participants in GE's Year
2000 effort are its finance organization, including the corporate audit staff,
and the corporate legal staff. Appropriate outside resources have also been
retained, including technical and legal consultants.

    NBC, including the NBC Multimedia Division, has prepared inventories,
assessed many of its systems and is remediating or replacing the systems which
may be affected by Year 2000. In addition, NBC has prepared "time-warp tests"
and "cluster tests" testing entire systems, including those of the NBC
Multimedia Division, to catch failures in interoperability between systems.

    Although NBC believes that it will be Year 2000 compliant, NBC's contributed
Internet businesses are highly dependent upon third party equipment and software
that may not be Year 2000 compliant.

    NBC Multimedia Division has placed its vendors and suppliers in priority
categories according to their importance to its business. NBC has sent letters
to all critical third party service suppliers, including those of the NBC
Multimedia Division, asking about the status of their Year 2000 programs. Vendor
readiness is being assessed and tracked. All vendors responding to date have
asserted that their products will be Year 2000 compliant. In the event NBC does
not receive satisfactory commitments from a key supplier, NBC is making plans
for continuing availability of service through alternate channels. NBC expects
to have certification that all key vendors and suppliers, including those of the
NBC Multimedia Division, are Year 2000 compliant by the end of third quarter of
1999.

    The failure of a major supplier to convert its systems on a timely basis or
in a manner compatible with the systems of the NBC Multimedia Division causing
any of the businesses to incur unanticipated expenses to remedy any problem
could adversely affect the operations of the NBC Multimedia Division.

    COSTS TO ADDRESS YEAR 2000 ISSUES

    To date, the NBC Multimedia Division has not incurred any material
expenditure in connection with identifying or evaluating Year 2000 compliance
issues. Most of NBC's expenses have been related to the opportunity cost of time
spent by its employees evaluating NBC's technologies. The costs to evaluate or
address Year 2000 issues relating to the NBC Multimedia Division is not expected
to be

                                      214
<PAGE>
material. However, the full impact of the Year 2000 issues cannot be determined
at this time. The failure by third parties to address their Year 2000 issues on
a timely basis could adversely affect the NBC Multimedia Division.

    CONTINGENCY PLANS

    NBC has developed an extensive program to prepare Year 2000 specific
business continuity plans. Each of its businesses, including the NBC Multimedia
Division, is required to identify critical business processes and to prepare
plans to minimize the impact of any internal or external failures. NBC expects
to have such plans, including those of the NBC Multimedia Division, in place by
the end of the third quarter of 1999.

    RISKS

    The worst case scenario related to Year 2000 issues would involve a major
shutdown of the Internet, which would result in a total loss of revenue to the
NBC Multimedia Division until it was resolved. Internally, the most likely worst
case scenario would be that the NBC Multimedia Division would have problems with
off-line batch processes that stall or generate incorrect information. This
could result in a substantial delay in billing customers and preparing financial
statements.

IMPACT OF RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and for hedging activities. SFAS No. 133 is
effective for all fiscal quarters of fiscal years beginning after June 15, 2000.
The impact of adopting SFAS No. 133 has not yet been determined.

                          COMPARISON OF CAPITAL STOCK

DESCRIPTION OF NBCI CAPITAL STOCK

    Upon the closing of the contribution agreement, the authorized capital stock
of NBCi will consist of 100,000,000 shares of Class A common stock, $0.0001 par
value per share, 100,000,000 shares of Class B common stock, $0.0001 par value
per share and 10,000,000 shares of preferred stock, $0.0001 par value per share.

    NBCI COMMON STOCK


    As of August 31, 1999, 100 shares of NBCi Class A common stock were
outstanding, all of which were held by Xoom.com. After giving effect to the
transactions contemplated by the merger agreement and the contribution
agreement, there will be approximately 27,365,472 shares of Class A common stock
outstanding and 24,550,708 shares of Class B common stock outstanding. The
number of shares of Class A common stock is subject to adjustment based on
changes in the number of outstanding shares of Xoom.com's common stock. The
number of outstanding shares of Xoom.com's common stock may increase due to the
issuance of additional shares upon the exercise of options or in transactions
separate from those contemplated in this proxy statement/prospectus.


    The holders of Class A common stock and Class B common stock will have
identical economic rights except that the Class B common stock will not be
publicly traded. Except for those matters discussed below under "--NBCi
Certificate of Incorporation and Bylaws," the holders of Class A common stock
and Class B common stock will have the same governance rights and are entitled
to one vote for each share held of record on all matters submitted to a vote of
the stockholders. In addition, only NBC and its affiliates may own the Class B
common stock. Stockholders of NBCi will not have cumulative voting rights in the
election of directors. Subject to preferences that may be granted to any then
outstanding preferred stock, holders of common stock are entitled to receive
ratably such dividends as may be declared by the board of directors out of funds
legally available therefor as well as any distributions to the stockholders. In
the event of NBCi's liquidation, dissolution or winding up, holders of common
stock are entitled to share ratably in all of NBCi's assets remaining after
payment of liabilities and the liquidation preference of any then outstanding
preferred stock. Holders of common stock have no preemptive or other
subscription or conversion rights under NBCi's restated certificate of
incorporation. NBC, however, does have the right to purchase additional shares
of NBCi's Class B common stock under specific circumstances as described below
under "--Other Agreements". There are no redemption or sinking fund provisions
applicable to the common stock.

    PREFERRED STOCK

    NBCi has 10,000,000 shares of preferred stock authorized. As of the record
date, no shares were outstanding. Subject to the terms of its restated
certificate of incorporation, the NBCi board of directors has the authority to
issue these shares of preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions, qualifications and limitations
granted to or imposed upon any unissued and undesignated shares of preferred
stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
stockholders. The NBCi board of directors, without stockholder approval except
as set forth below under "NBCi Certificate of Incorporation and
Bylaws--Stockholder Veto Rights," can issue preferred stock with voting and
conversion rights which could adversely affect the voting power or other rights
of the holders of NBCi common stock and the issuance of preferred stock may have
the effect of delaying, deferring or preventing a change in control of NBCi.

NBCI CERTIFICATE OF INCORPORATION AND BYLAWS

    In connection with the merger of Neon Media Corporation with NBCi under the
contribution agreement, NBCi's certificate of incorporation and bylaws will be
amended and restated. The following summary of the provisions of NBCi's restated
certificate of incorporation and restated bylaws may not contain all of the
information that may be important to investors and is qualified in its entirety
by reference to the provisions of the restated certificate of incorporation and
amended and restated bylaws, which are attached hereto as Appendix D-1 and
Appendix D-2, respectively.

    NUMBER OF DIRECTORS

    As long as shares of Class B common stock remain outstanding, the number of
directors of NBCi shall be thirteen. The number of directors may be increased
upon the occurrence of the circumstances discussed below, but shall return to
thirteen at the next annual or special meeting where directors are elected. The
restated certificate of incorporation currently provides that when no shares of
Class B common stock remain outstanding, the number of directors shall not be
less than seven nor more than sixteen.

    ELECTION OF DIRECTORS

    Under the restated certificate of incorporation, the holders of the Class A
common stock and the holders of Class B common stock are entitled to elect a
designated number of directors dependent upon the percentage of the outstanding
common stock of NBCi each class owns.

    For so long as the outstanding shares of Class B common stock represent at
least 35% of the outstanding shares of NBCi common stock and the NBCi
convertible notes have not been fully converted into shares of Class B common
stock:

    - the holders of the Class A common stock, voting separately as a class,
      have the right to elect six members to the board of directors, referred to
      as Class A Directors, and one unaffiliated director nominated by at least
      seven members of the board of directors; and

    - the holders of the Class B common stock, voting separately as a class,
      have the right to elect six members to the board of directors, referred to
      as the Class B Directors.

    The above rights shall also exist where the holders of a majority of the
outstanding shares of Class B Common Stock, voting separately as a class, elect
to reduce the number of directors they are otherwise entitled to elect from
seven to six, as set forth in the next paragraph, which election shall be
permanent.

    After the NBC convertible notes have been fully converted into shares of
Class B common stock, for so long as the outstanding shares of Class B common
stock represent at least 35% of outstanding shares of NBCi common stock:

    - the holders of the Class A common stock, voting separately as a class,
      have the right to elect six Class A Directors;

    - the holders of the Class B common stock, voting separately as a class,
      have the right to elect seven Class B Directors; and

                                      217
<PAGE>
    - the term of office of the unaffiliated director shall automatically
      terminate, unless the Class B nominating committee elects to retain the
      unaffiliated director as a Class B Director.

    Where the outstanding shares of Class B common stock is equal to or greater
than 20% but less than 35% of the outstanding shares of NBCi common stock:

    - the holders of the Class A common stock, voting separately as a class,
      have the right to elect seven Class A Directors;

    - the holders of the Class B common stock, voting separately as a class,
      have the right to elect six Class B Directors; and

    - the term of office of the unaffiliated director shall automatically
      terminate, unless the Class A nominating committee elects to retain the
      unaffiliated director as a Class A Director.

    If, at such time, there are seven Class B Directors, the holders of the
Class B common stock shall cause one Class B Director to resign within 30 days
after the Class B common stock constitutes less than 35% of the outstanding
common stock. If a Class B Director does not resign by such time, the number of
directors comprising the board of directors will automatically be increased to
fifteen and two additional Class A Directors will be appointed to the board of
directors. The number of directors shall automatically decrease to thirteen at
the next annual or special meeting of stockholders at which directors are
elected, at which time the board of directors shall be comprised of six Class B
Directors and seven Class A Directors.

    Concurrently with the conversion of all of the outstanding shares of Class B
common stock into shares of Class A common stock, as discussed below, the former
holders of the Class B common stock shall cease to have the absolute right to
designate or cause the nomination or election of any directors of NBCi. Each
Class B Director shall be automatically deemed a Class A Director and shall
continue to hold office for the unexpired portion of such director's term. NBC,
however, will have the right to designate nominees for election to the board of
directors pursuant to the terms of the governance agreement discussed below.

    NOMINATIONS AND VACANCIES

    CLASS A DIRECTORS.  Class A Directors are nominated on behalf of NBCi by the
Class A nominating committee comprised solely of Class A Directors. At such time
as the holders of the Class A common stock are entitled to elect additional
Class A Director(s) to the board of directors, the Class A nominating committee
may appoint such Class A Director(s). If a vacancy is created on the board of
directors by reason of the death, resignation or removal of a Class A Director,
a majority of the Class A Directors then in office, or the holders of Class A
common stock at a meeting called for such purpose, may fill the vacancy.

    CLASS B DIRECTORS.  Class B Directors are nominated on behalf of NBCi by the
Class B nominating committee comprised solely of Class B Directors. At such time
as the holders of the Class B common stock are entitled to elect an additional
Class B Director to the board of directors, the Class B nominating committee may
appoint such Class B Director. If a vacancy is created on the board of directors
by reason of the death, resignation or removal of a Class B Director, a majority
of the Class B Directors then in office, or the holders of Class B common stock
at a meeting called for such purpose, may fill the vacancy.

    UNAFFILIATED DIRECTOR.  For the unaffiliated director to be nominated for
election by the holders of the Class A common stock, at least seven directors of
NBCi must approve the nomination. The unaffiliated director's term automatically
expires at such time as either the holders of the Class A common stock or the
holders of the Class B common stock have the right to elect a majority of the
members to the board of directors, provided that the Class A nominating
committee or the Class B

                                      218
<PAGE>
nominating committee, as the case may be, may elect to retain the unaffiliated
director in lieu of appointing a new person to the board of directors.

    REMOVAL OF DIRECTORS

    A Class A Director may be removed, without cause, only by the affirmative
vote of the holders of a majority of the outstanding shares of Class A common
stock. A Class B Director may be removed, without cause, only by the affirmative
vote of the holders of a majority of the outstanding shares of Class B common
stock.

    The unaffiliated director may be removed, without cause, only by the
affirmative vote of the holders of at least 70% of the outstanding shares of
NBCi common stock.

    APPOINTMENT AND REMOVAL OF OFFICERS

    So long as there are Class B Directors, the Class B Directors shall have the
exclusive power and authority to appoint the chief financial officer and general
counsel of NBCi and remove the chief executive officer.

    CONVERSION OF CLASS B COMMON STOCK INTO CLASS A COMMON STOCK

    VOLUNTARY CONVERSION.  Upon the affirmative vote or written request of the
holders of a majority of the outstanding shares of Class B common stock for the
conversion of the Class B common stock into Class A common stock, all, but not
less than all, of the outstanding shares of Class B common stock shall
automatically convert on a share for share basis into the same number of shares
of Class A common stock. NBCi will also permit the parent corporation of NBC and
its affiliates, to convert shares of Class A common stock held by such person
into shares of Class B common stock upon written request and subject to the
terms and conditions of the governance agreement.

    MANDATORY CONVERSION.  Shares of Class B common stock will automatically be
converted into shares of Class A common stock upon the occurrence of the
following events:

    - any sale, assignment or transfer of shares of Class B common stock by NBC
      or any of its affiliates, other than a transfer to an affiliate of such
      holder, or

    - at such time as the holders of Class B common stock beneficially own less
      than 20% of the outstanding shares of NBCi common stock immediately prior
      to the time of conversion, after giving effect to NBC's right to purchase
      additional shares of Class B common stock under the governance agreement.

    AUTOMATIC CONVERSION OF CLASS A COMMON STOCK.  So long as shares of Class B
common stock are outstanding, in the event a holder of Class B common stock or
its subsidiary holds, purchases or otherwise acquires any shares of Class A
common stock (other than as a result of a conversions described above), then
such shares of Class A common stock shall automatically convert on a share for
share basis into the same number of shares of Class B common stock.

    ACTION BY WRITTEN CONSENTS

    Action may be taken by written consent in lieu of a stockholders meeting
only when the Class B common stock constitutes a majority of the outstanding
shares of common stock of NBCi.

    VETO RIGHTS OF DIRECTORS

    VETO RIGHTS OF CLASS A DIRECTORS.  As long as the holders of Class B common
stock have the right to elect seven directors, the following actions require the
approval of a majority of the Class A Directors:

                                      219
<PAGE>
    - any amendment to the restated certificate of incorporation or restated
      bylaws;

    - entering into, altering or amending any agreement or engaging in any
      transactions or series of transactions with NBC or its affiliates that (A)
      is not on an arm's-length basis or entered into in the ordinary course of
      business or (B) involves an amount, individually or in the aggregate, in
      excess of $50,000,000;

    - the voluntary filing of a petition for bankruptcy or receivership or the

      receiver of NBCi;

    - the appointment of a new chief executive officer of NBCi;

    - the adoption of NBCi's annual or other operating budgets and strategic
      plans;

    - the adoption of a stockholder rights plan or other action which could
      adversely affect the rights of any holder of Class A common stock by
      virtue of the amount of shares held by such holder; and

    - the issuance of any equity securities other than Class A common stock or
      Class B common stock.

    VETO RIGHTS OF CLASS B DIRECTORS.  For so long as the Class B Directors do
not constitute a majority of the board of directors, the approval of a majority
of the Class B Directors will be required to take any of the following actions
and the veto rights of the Class A Directors described above shall no longer be
of any force or effect:

    - any of the actions listed above under "--Veto Rights of Class A Directors"

    CORPORATE OPPORTUNITIES

    In recognition that NBCi and NBC may engage in the same or similar
activities or lines of business and have an interest in the same or similar
areas of corporate opportunities, the restated certificate of incorporation
provides:

    - that NBC has the right to engage in the same or similar activities or
      lines of business as NBCi, do business with any potential or actual
      customers or suppliers of NBCi or employ or otherwise engage any officer
      or employee of NBCi;

    - that to the fullest extent provided by law, neither NBC nor any of its
      officers or directors shall be liable to NBCi or its stockholders for
      breach of any fiduciary duty due to NBC or any of its officers or
      directors engaging in the above opportunities; and

    - that NBC shall not be liable for the breach of any fiduciary duty as a
      stockholder of NBCi if (a) NBC pursues or acquires a corporate opportunity
      for itself, or (b) directs such corporate opportunity to another person,
      or (c) fails to communicates such opportunity to NBCi.

    In the event that a director or officer of NBCi is also a director or
officer of NBC and such director or officer acquires knowledge of a corporate
opportunity, such director or officer:

    - shall be deemed to have fully satisfied the fiduciary duty such person
      owes to NBCi and its stockholders with respect to that corporate
      opportunity,

    - shall not be deemed liable to NBCi or its stockholders for pursuing such
      corporate opportunity on behalf of NBC,

    - shall be deemed to have acted in good faith, and

    - shall not be deemed to have breached the duty of loyalty to NBCi or its
      stockholders, if such person acts in a manner consistent with the
      following policy:

       - a corporate opportunity offered to any person who is an officer of
         NBCi, and who is also a director but not an officer of NBC, shall
         belong to NBCi;

       - a corporate opportunity offered to any person who is a director but not
         an officer of NBCi, and who is also a director or officer of NBC, shall
         belong to NBCi if such opportunity is expressly offered to such person
         in writing solely in his or her capacity as a director of NBCi,
         otherwise it shall belong to NBC; and

       - a corporate opportunity offered to any person who is an officer of both
         NBCi and NBC shall belong to NBCi if such opportunity is expressly
         offered to such person in writing solely in his or her capacity as an
         officer of NBCi, otherwise it shall belong to NBC.

    The restated certificate of incorporation also provides that any corporate
opportunity that belongs to NBC or to NBCi shall not be pursued by the other
party. If the corporate opportunity is not pursued diligently and in good faith
within 30 calendar days, the other party may pursue such corporate opportunity.
In addition, the approval of a majority of the Class A Directors is required to
commence any action, suit or proceeding against NBC or its affiliates or enter
into any transaction or arrangement with NBC or its affiliates, where such
arrangement would otherwise require the action of the full board of directors.

                                      221
<PAGE>
    Any amendment of the corporate opportunity provisions set forth in the
restated certificate of incorporation in a manner adverse to NBC requires the
approval of stockholders holding at least 80% of the outstanding shares of
common stock of NBCi.

    The provisions contained in NBCi's restated certificate of incorporation
regarding corporate opportunities as described above shall expire on the date
that (a) NBC ceases to beneficially own at least 20% of the voting power of the
outstanding shares of NBCi's common stock, and (b) no person who is a director
or officer of NBCi is also a director or officer of NBC.

OTHER AGREEMENTS

    The governance and investor rights agreement between NBCi and NBC will
provide, among other things:

    - that when no shares of Class B common stock remain outstanding and NBC or
      its affiliates beneficially own at least 5% of the outstanding shares of
      NBCi common stock, NBC shall have the right to designate nominees for
      election to the board of directors equal to the greater of:

       - one, or

       - a number equal to the number of current directors multiplied by NBC's
         percentage ownership of NBCi common stock, rounded to the nearest whole
         number.

    In addition, under the governance agreement NBC will have an option to
purchase additional shares of Class B common stock in an amount sufficient to
retain its percentage ownership interest in NBCi as it stood immediately prior
to the issuance of the additional shares of common stock by NBCi. This option
will expire when no shares of Class B common stock remain outstanding.

    NBC and CNET will enter into a voting and right of first offer agreement
that will require, among other things, CNET to vote its shares of NBCi in the
same manner as NBC regarding a change of control transaction or a transaction
that would result in the acquisition or sale of 5% or more of NBCi's equity
securities should such transaction be submitted to NBCi's stockholders for
approval. CNET also grants a right of first offer to NBC under this agreement
with respect to any proposed sale or transfer of CNET's shares of NBCi to a
third party.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF NBCI'S CHARTER AND BYLAWS

    NBCi's amended and restated bylaws provide that all stockholder action must
be effected at a duly called meeting of stockholders and not by a consent in
writing, except where the Class B common stock constitutes a majority of the
outstanding shares of NBCi common stock. The amended and restated bylaws also
provide that only the chairman of the board, the chief executive officer or
president, the board of directors or the holders of a majority of the
outstanding shares of Class B common stock may call a special meeting of
stockholders.

    These provisions, the provisions of NBCi's restated certificate of
incorporation discussed above and NBC's ownership interest in NBCi will make it
more difficult for NBCi's existing stockholders to replace the board of
directors as well as for another party to obtain control by replacing the board
of directors. Since the board of directors has the power to retain and discharge
NBCi's officers, these provisions could also make it more difficult for existing
stockholders or another party to effect a change in management.

    These and other provisions may have the effect of deterring hostile
takeovers or delaying changes in control or management. These provisions are
intended to enhance the likelihood of continued stability in the composition of
the board of directors and in the policies furnished by the board of directors
and to discourage the types of transactions that may involve an actual or
threatened change of control. These provisions are designed to reduce NBCi's
vulnerability to an unsolicited acquisition

                                      222
<PAGE>
proposal and are also intended to discourage tactics that may be used in proxy
fights. However, this could have the effect of discouraging others from making
tender offers for NBCi's shares and, as a consequence, may inhibit fluctuations
in the market price of NBCi's shares that could result from actual or rumored
takeover attempts. These provisions also may have the effect of preventing
changes in NBCi's management.

SECTION 203 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

    NBCi is subject to Section 203 of the General Corporation Law of the State
of Delaware, which, subject to some exceptions, prohibits a Delaware corporation
from engaging in any business combination with any interested stockholder for a
period of three years following the time that such stockholder became an
interested stockholder, unless:

    - prior to such time, the board of directors of the corporation approved
      either the business combination or the transactions that resulted in the
      stockholder becoming an interested holder;

    - upon consummation of the transactions that resulted in the stockholder
      becoming an interested stockholder, the interested stockholder owned at
      least 85% of the voting stock of the corporation outstanding at the time
      the transactions commenced, excluding for purposes of determining the
      number of shares outstanding:

       - those shares owned by persons who are directors and also officers, and

       - those shares issuable pursuant to employee stock plans in which
         employee participants do not have the right to determine confidentially
         whether shares held subject to the plan will be tendered in a tender or
         exchange offer; or

    - on or subsequent to such time, the business combination is approved by the
      board of directors and authorized at an annual or special meeting of the
      stockholders, and not by written consent, by the affirmative vote of at
      least 66 2/3% of the outstanding voting stock that is not owned by the
      interested stockholder.

    Section 203 defines a business combination to include:

    - any merger or consolidation involving the corporation and the interested
      stockholder;

    - any sale, transfer, pledge or other disposition of 10% or more of the
      assets of the corporation involving the interested stockholder;

    - subject to some exceptions, any transaction that results in the issuance
      or transfer by the corporation of any stock of the corporation to the
      interested stockholder;

    - any transactions involving the corporation that have the effect of
      increasing the proportionate share of the stock of any class or series of
      the corporation beneficially owned by the interested stockholder; or

    - the receipt by the interested stockholder of the benefit of any loans,
      advances, guarantees, pledges or other financial benefits by or through
      the corporation.

In general, Section 203 defines an interested stockholder as an entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.

required to indemnify, in the manner and to the full extent permitted by the
General Corporation Law of the State of Delaware, any person made or threatened
to be made a party to a proceeding (whether civil, criminal or otherwise) by
reason of the fact that such person, or a person of whom such person is the
legal representative, is or was a director or officer of Xoom.com or by reason
of the fact that such director or officer was acting in any other capacity while
serving as a director or officer. In addition, under Xoom.com's certificate of
incorporation, a director is not liable for monetary damages to the corporation
or its stockholders for breach of fiduciary duty as a director; provided
however, a director will be liable to the extent provided by applicable law:

    - for any breach of the director's duty of loyalty to Xoom.com or its
      stockholders,

    - for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of the law,

      any of its directors, officers or agents and may advance the expenses of
      any current or former director, officer, employee or trustee in defending

      by the board of directors, no person will be entitled to indemnification
      or to advances with respect to any action brought by them against Xoom.com
      other than an action to recover or enforce such person's right to
      indemnification or advance.

substantially the same rights and obligations.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders of Xoom.com, Inc.

    We have audited the accompanying consolidated balance sheets of Xoom.com,
Inc. as of December 31, 1997 and 1998, and the related consolidated statements
of operations, stockholders' equity (deficit) and cash flows for the period from
April 16, 1996 (inception) through December 31, 1996 and for the years ended
December 31, 1997 and 1998. These financial statements are the responsibility of
Xoom.com, Inc.'s management. Our responsibility is to express an opinion on
these financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Xoom.com, Inc. at December 31, 1997 and 1998, and the consolidated results of
its operations and its cash flows for the period from April 16, 1996 (inception)
through December 31, 1996 and for the years ended December 31, 1997 and 1998 in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   (INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

    Xoom.com, Inc. (the "Company"), was formerly known as XOOM, Inc., Xoom
Software, Inc. and originally incorporated as Atomsoft, Inc. in the State of
Delaware on April 16, 1996.

    The Company provides free community services such as Web site hosting,
e-mail, on-line chat networks and free proprietary content such as clip art and
greeting cards. The Company uses these free services and content to build a
membership base to direct market goods and services targeted to the interests of
its members. The Company derives a substantial portion of its revenue from
e-commerce, and to a lesser extent from advertising and licensing.

BASIS OF PRESENTATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany transactions and
balances have been eliminated in consolidation.

DEPENDENCE ON CERTAIN VENDORS

    The Company currently depends on one vendor to provide warehousing and order
fulfillment. Although the Company believes that there are alternative vendors
for warehousing and order fulfillment, there can be no assurance that the
Company will maintain its relationship with this vendor as the agreement is
cancelable at any time. The loss of this relationship could have a material
adverse effect on the Company's financial condition and results of operations.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported results of operations during the reporting period. Actual results
could differ from those estimates.

INTERIM FINANCIAL INFORMATION

    The interim financial information as of June 30, 1998 and 1999, and for the
six months ended June 30, 1998 and 1999, is unaudited but has been prepared on
the same basis as the audited financial statements and includes all adjustments,
consisting only of normal recurring adjustments, that the Company considers
necessary for a fair presentation of its financial position at such date and its
results of operations and cash flows for those periods. Operating results for
the six months ended June 30, 1998 and 1999 are not necessarily indicative of
results that may be expected for any future periods.

CASH AND CASH EQUIVALENTS

    The Company considers investments in highly liquid instruments purchased
with original maturities of 90 days or less to be cash equivalents. Cash
equivalents are recorded at cost, which approximates fair value. The Company
maintains its cash in depository accounts with three high credit quality
financial institutions.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

   (INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CONCENTRATIONS OF CREDIT RISK AND CREDIT EVALUATIONS

    Financial instruments which subject the Company to concentrations of credit
risk consist primarily of trade accounts receivable. The Company conducts
business with companies in various industries throughout the world and with
individuals over the Internet. The Company performs ongoing credit evaluations
of its corporate customers and generally does not require collateral. Sales to
individuals are principally paid for via credit cards. Reserves are maintained
for potential credit losses, and such losses to date have been within
management's expectations. The Company provided $49,000 and $269,000 for
allowance for doubtful accounts in 1997 and 1998, respectively.

    For the year ended December 31, 1997, one customer accounted for $100,000 or
12% of total net revenue. No balances were receivable from that customer at
December 31, 1997. For the year ended December 31, 1998, no single customer
accounted for greater than 10% of total net revenue.

INVENTORIES

    Inventories are carried at the lower of cost (determined on the average cost
basis) or market. Inventories consist of products available for sale.

FIXED ASSETS

    Fixed assets are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method over the
estimated useful lives of three years. Fixed assets under capital leases are
amortized over the shorter of the estimated useful life or the life of the
lease. The Company identifies and records impairment losses on fixed assets when
events and circumstances indicate that such assets might be impaired. To date,
no such impairment has been recorded.

GOODWILL AND PURCHASED TECHNOLOGY, NET

    Goodwill and purchased technology consist of purchased technology and
goodwill related to acquisitions accounted for by the purchase method. See Note
2. Amortization of these purchased intangibles is provided on the straight-line
basis over the respective useful lives of the assets, which ranges from 2 to 3.5
years. Purchased in-process research and development without alternative future
use is expensed when acquired.

    The Company identifies and records impairment losses on intangible assets
when events and circumstances indicate that such assets might be impaired. To
date, no such impairment has been recorded.

PREPAID ROYALTIES AND LICENSES

    Prepaid royalties represent prepayments of royalties due upon the sale or
sublicense of software technologies. Prepaid royalties are amortized as units
are sold or over estimated useful lives of approximately one year, whichever is
shorter. Licenses represent amounts paid to developers for fully paid licenses
to resell certain software. These licenses are amortized over the estimated
useful lives which are approximately one year. Amortization of prepaid royalties
and licenses, which is included in cost of e-commerce and cost of license fee
revenue, totaled $0, $213,000 and $263,000, for the period from

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
April 16, 1996 (inception) to December 31, 1996, and for the years ended
December 31, 1997 and 1998, respectively.

    During the second quarter of 1997, the Company discontinued the sale of
certain products where royalty prepayments had been made and accordingly,
recorded a write-off of prepaid royalties included in non-recurring charges
totaling $243,000.

OTHER ASSETS

    Other assets consist of non-current deposits relating to various ongoing
agreements entered into by the Company.

DEFERRED REVENUE

    Deferred revenue consists of advertising and e-commerce fees to be earned in
the future under agreements existing at the balance sheet date.

INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"), which requires the use of the liability method in accounting for income
taxes. Under FAS 109, deferred tax assets and liabilities are measured based on
differences between the financial reporting and tax bases of assets and
liabilities using enacted tax rates and laws that are expected to be in effect
when the differences are expected to reverse.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based awards to employees under the intrinsic
value method in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and has adopted the
disclosure-only alternative of Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" ("FAS 123").

REVENUE RECOGNITION

E-COMMERCE

    The Company recognizes revenue from e-commerce sales when the products are
shipped to customers. The Company provides for potential product returns and
estimated warranty costs in the period of the sale. Such costs have been minimal
to date.

ADVERTISING

    Advertising revenues are derived from the sale of banner advertisements and
sponsorships under short-term contracts. Through December 31, 1998, the duration
of the Company's advertising commitments has been principally from one to two
months to a year. Advertising revenues on banner contracts are recognized
ratably in the period in which the advertisement is displayed, provided that no
significant Company obligations remain and collection of the resulting
receivable is probable. Company obligations typically include the guarantee of a
minimum number of "impressions" or times that an advertisement

appears in pages viewed by the users of the Company's online properties. To the
extent minimum guaranteed impressions are not met, the Company defers
recognition of the corresponding revenue until the remaining guaranteed
impression levels are achieved.

LICENSE FEES

    The Company licenses software under non-cancelable license agreements to
end-users and non-cancelable sub-license agreements to resellers. License fee
revenues are recognized when a non-cancelable license agreement has been signed,
the product has been delivered, there are no uncertainties surrounding product
acceptance, the fees are fixed and determinable, collection is considered
probable and all significant contractual obligations have been satisfied.

EXPORT SALES

    Export sales were 30% and 25% of net revenues for the years ended December
31, 1997 and 1998, respectively. The Company's export sales are as follows (in
thousands):

ADVERTISING EXPENSE

    All advertising costs are expensed when incurred. Advertising costs, which
are included in sales and marketing expense, were $0, $50,000 and $51,000, for
the period from April 16, 1996 (inception) through December 31, 1996, and for
the years ended December 31, 1997 and 1998, respectively.

DEVELOPMENT COSTS

    Development costs are expensed as incurred and are included in operating and
development expenses.

COMPUTATION OF NET LOSS PER SHARE

    The Company computes net loss per share based on Financial Accounting
Standards Board Statement No. 128, "Earnings Per Share," ("SFAS 128"). In
accordance with SFAS 128, basic net income (loss) per share excludes dilutive
common stock equivalents and is calculated as net income (loss) divided by the
weighted average number of common shares outstanding. Diluted net income (loss)
per share is computed using the weighted average number of common shares

RECENT ACCOUNTING PRONOUNCEMENTS

    As of January 1, 1998 the Company adopted Financial Accounting Standards
Board Statement No. 130 ("SFAS 130"), "Reporting Comprehensive Income," which
establishes standards for reporting and displaying comprehensive income and its
components in a full set of general-purpose financial statements. The Company
had no material components of comprehensive income for the year ended December
31, 1998. Accordingly, the Company's comprehensive loss for the year ended
December 31, 1998 is equal to its reported loss. The Company's comprehensive
loss for the six months ended June 30, 1999 was approximately $7,160,000.

    Additionally, the Financial Accounting Standards Board issued Financial
Accounting Standards Board Statement No. 131 ("SFAS 131") "Disclosure about
Segments of an Enterprise and Related Information," which establishes standards
for the way public business enterprises report information in annual statements
and interim financial reports regarding operating segments, products and
services, geographic areas, and major customers. This statement is effective for
financial statements for periods beginning after December 15, 1997. The Company
adopted SFAS 131 in 1998. The Company operates in one business segment, Internet
service to customers.

    In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use", which establishes guidelines
for the accounting for the costs of all computer software developed or obtained
for internal use. The Company is required to adopt SOP 98-1 effective January 1,
1999. The adoption of SOP 98-1 is not expected to have a material impact on the
Company's consolidated financial statements.

2. BUSINESS COMBINATIONS AND TECHNOLOGY ACQUISITIONS

    During the year ended December 31, 1998 and the six months ended June 30,
1999, the Company made the business and technology acquisitions described in the
paragraphs that follow, each of which has been accounted for as a purchase. The
consolidated financial statements include the operating results of each business
from the date of acquisition.

    The amounts allocated to purchased research and development were determined
through established valuation techniques in the high-technology Internet
industry and were expensed upon acquisition, because technological feasibility
had not been established and no future alternative uses existed. Research and
development costs to bring the products from the acquired companies to
technological feasibility are not expected to have a material impact on the
Company's future results of operations or cash flows.

    PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT.  The amounts allocated to
purchased research and development were determined through established valuation
techniques in the high-technology Internet industry and were expensed upon
acquisition, because technological feasibility had not been established and no
future alternative uses existed. The values assigned to purchased in-process
technology were determined by identifying the on-going research projects for
which technological feasibility had not been achieved and assessing the state of
completion of the research and development effort. The state of

   (INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)

2. BUSINESS COMBINATIONS AND TECHNOLOGY ACQUISITIONS (CONTINUED)
completion was determined by estimating the costs and time incurred to date
relative to those costs and time to be incurred to develop the purchased
in-process technology into commercially viable products, estimating the
resulting net cash flows only from the percentage of research and development
efforts complete at the date of acquisition, and discounting the net cash flows
back to their present value. The discount rate included a factor that took into
account the uncertainty surrounding the successful development of the purchased
in-process technology projects.

    PURCHASED TECHNOLOGY.  To determine the values of purchased technology, the
expected future cash flows of the existing developed technologies were
discounted taking into account the characteristics and applications of the
product, the size of existing markets, growth rates of existing and future
markets as well as an evaluation of past and anticipated product lifecycles.

    ACQUIRED WORKFORCE.  To determine the values of the acquired workforce,
employees were identified who would require significant cost to replace and
train. Then each employee's fully-burdened cost (salary, benefits, overhead),
the cost to train the employee, and the recruiting costs (locating,
interviewing, hiring) were estimated. These costs were then summed up and tax
effected to estimate the value of the assembled workforce.

    Amounts allocated to purchased technology, goodwill and other intangible
assets are being amortized on a straight-line basis over periods of two to four
years.

PARALOGIC CORPORATION

    On March 10, 1998, the Company acquired 100% of the outstanding shares of

    SUMMARY OF PURCHASED IN-PROCESS RESEARCH AND DEVELOPMENT AND PURCHASED
TECHNOLOGY. Values assigned to purchased in-process research and development and
purchased technology were generally determined using an income approach. To
determine the value of in-process research and development, the Company
considered, among other factors, the state of completion of each project, the
time and cost needed to complete each project, expected income, and associated
risks which included the inherent

difficulties and uncertainties in completing the project and thereby achieving
technological feasibility and risks related to the viability of and potential
changes to future target markets. This analysis results in amounts assigned to
in-process research and development projects that had not yet reached
technological feasibility (as defined and utilized by the Company in assessing
software capitalization) and does not have alternative future uses. To determine
the value of the purchased technology, the expected future cash flows of each
existing technology product were discounted taking into account risks related to
the characteristics and applications of each product, existing and future
markets and assessments of the life cycle stage of the product. Based on the
analysis, the existing technology that had reached technological feasibility was
capitalized. The intangible assets as of June 30, 1999 are summarized as follows

financing company which provided for borrowings up to $2,750,000. The loan bore
interest of 12% annually. All amounts borrowed under this loan agreement were
secured by certain fixed assets. Pursuant to the terms of the loan agreement,
the Company issued the lender a warrant to purchase 183,333 shares of the
Company's common stock at an exercise price equal to the initial public offering
price per share. The Company determined that the fair value of the warrant to be
$1,494,000 at the date of the initial public offering, and in connection with
this issuance recorded the fair value as interest expense. The effective
interest rate on this secured loan agreement for the year ended December 31,
1998 was approximately 1,450%. As of December 31, 1998, all outstanding
principal and interest amounts had been fully paid and the loan agreement had
been canceled.

7. INCOME TAXES (CONTINUED)

    Realization of deferred tax assets is dependent upon future earnings, if
any, the timing and amount of which are uncertain. Accordingly, the net deferred
tax assets have been fully offset by a valuation allowance as it is more likely
than not that the deferred tax assets will not be realized.

    During the period from April 16, 1996 (inception) through December 31, 1996,
and during the years ended December 31, 1997 and 1998, the valuation allowance
for the deferred tax assets increased by $175,000, $1,146,000 and $2,452,000,
respectively.

    As of December 31, 1998, the Company had net operating loss carryforwards
for federal income tax purposes of approximately $4,878,000. There can be no
assurance that the Company will realize the benefit of the net operating loss
carryforwards. The federal net operating loss carryforwards will expire at
various dates beginning in the fiscal year 2011 through 2018 if not utilized.

    Due to the "change of ownership" provisions of the Internal Revenue Code,
the availability of the Company's net operating loss and credit carryforwards
will be subject to an annual limitation against taxable income in future periods
if a change in ownership of more than 50% of the value of the Company's stock
should occur over a three year period, which could substantially limit the
eventual utilization of these carryforwards.

8. COMMITMENTS

    The Company leases its facilities, furniture and fixtures and certain
computers and equipment under noncancelable leases for varying periods through
2007. The cost of assets acquired under capital leases during the year ended
December 31, 1998 was $165,000. Amortization expense related to these assets of
$18,000 is included in accumulated depreciation and amortization at December 31,
1998. The following are the minimum lease obligations under these leases at
December 31, 1998 (in thousands):

9. CONTINGENCY ACCRUAL AND OTHER MATTER

    In January 1998, the Company became aware that Imageline, Inc. ("Imageline")
claimed to own the copyright in certain images that a third party, Sprint
Software Pty Ltd ("Sprint") had licensed to the Company. Some clip art images
that Imageline alleged infringed Imageline's copyright were included by the
Company in versions of the Company's Web Clip Empire product and licensed by the
Company to third parties, including other software clip publishers. The
Company's contracts with such publishers require the Company to indemnify the
publisher if copyrighted material licensed from the Company infringes a
copyright. Imageline claims that the Company's infringement of Imageline's
copyrights is ongoing. The Company and Imageline had engaged in discussions, but
were unable to reach any agreement regarding a resolution of this matter.

    On August 27, 1998, the Company filed a lawsuit in the United States
District Court for the Eastern District of Virginia against Imageline, certain
parties affiliated with Imageline, and Sprint regarding the Company's and its
licensees' alleged infringement on Imageline's copyright in certain clip art
that the Company licensed from Sprint. The lawsuit seeks, among other relief,
disclosure of information from Imageline concerning the alleged copyright
infringement, a declaratory judgment concerning the validity and enforceability
of Imageline's copyrights and copyright registrations, a declaratory judgment
regarding damages, if any, owed by the Company to Imageline, and indemnification
from Sprint for damages, if any, owed by the Company to Imageline. There is no
contractual limitation on Sprint's indemnification. While the Company is seeking
indemnification from Sprint for damages, if any, there can be no assurance that
Sprint will be able to fulfill the indemnity obligations under its license
agreements with the Company. In addition, the Company may be subject to claims
by third parties seeking indemnification from the Company in connection with the
alleged infringement of the Imageline copyrights.

    On September 17, 1998, Imageline filed a counterclaim, which Imageline
amended in January 1999, seeking up to $60 million in damages. In March 1999,
the parties completed the discovery process and filed separate motions for
summary judgment.

    On April 5, 1999, the Court granted one of the Company's motions for partial
summary judgment and stayed the case to allow Imageline to file all necessary
copyright registration applications to cover the clip art images.

    Based on the discussions with Imageline, the Company believes the range of
liability related to this matter is from $0 up to $10,000,000; however, the
Company believes it is unlikely that the liability would exceed $1,000,000.
Accordingly, the Company reserved $1,000,000 for this potential liability, the
expense of which is included in non-recurring charges for the year ended
December 31, 1997. The Company believes that the $1,000,000 accrual represents a
reasonable estimate of the loss that could be incurred in the Imageline dispute.
Based on information available to date management does not believe that the
outcome of this matter will have a material effect on the Company's financial
position, results of operations and cash flows over and above the $1,000,000
accrued in the 1998 financial statements. If not successful in defending this
claim, the resulting outcome could have a material adverse impact on the
Company's business, results of operations, cash flows and financial condition.

    Zoom Telephonics, Inc. filed a lawsuit against the Company in September 1998
alleging trademark infringement and related statutory violations. The Company
was not served with Zoom Telephonics' complaint until January 1999. Zoom
Telephonics has demanded that the Company stop using the XOOM trademark and has
asked for an unspecified amount of money damages. The Company responded to the

complaint in February 1999. In April 1999, Zoom Telephonics filed a motion for a
preliminary injunction to stop the Company from using any mark containing
"Xoom."

    In June 1999 the Company filed an opposition to Zoom Telephonics' motion for
preliminary injunction and filed a motion to suspend all proceedings in this
matter until September 30, 1999. Although the Company believes that Zoom's
claims are without merit, such litigation could have a material adverse effect
on the Company's business, results of operations and financial condition,
particularly if such litigation forces the Company to make substantial changes
to its name and trademark usage.

10. STOCKHOLDERS' EQUITY

    In October 1998, the Company's Board of Directors authorized an increase in
the number of authorized shares of common stock and preferred stock from
20,000,000 to 40,000,000 and 1,000,000 to 5,000,000, respectively, each with a
par value of $.0001 per share.

    On December 9, 1998, the Company completed its Initial Public Offering and
issued 4,600,000 shares (including 600,000 shares issued in connection with the
exercise of the underwriter over-allotment option) of its common stock to the
public at a price of $14.00 per share. The Company received net proceeds of
$57,341,000.

    On April 9, 1999, the Company completed a secondary public offering of its
common stock and issued 4,600,000 shares (including 600,000 shares issued in
connection with the exercise of the underwriter over-allotment option) at a
price of $66.00 per share. Of the 4,600,000 shares of common stock sold in the
offering, 2,659,800 were sold by the Company and 1,940,200 shares were sold by
existing stockholders. The Company received net proceeds from the offering of
approximately $167 million.

COMMON STOCK

    In May, the Board of Directors voted to increase the number of authorized
shares to 80,000,000.

1998 EMPLOYEE STOCK PURCHASE PLAN

    The Company's 1998 Employee Stock Purchase Plan was terminated by the Board
of Directors in May 1999.

FOUNDERS STOCK

    Pursuant to a Common Stock Purchase Agreement dated August 26, 1996 and
following the incorporation of the Company, two of the Company's founders each
purchased 333,334 shares (666,668 shares in total) of the Company's common stock
for an aggregate of $200 in cash. Pursuant to a Common Stock Purchase Agreement
dated December 31, 1996, the founders purchased an additional 2,333,334 and
1,000,000 shares, respectively, of the Company's common stock in exchange for
the cancellation of promissory notes that the Company owed to the
stockholders/founders in the amount of $700,000 and $300,000, respectively. In
the same agreement, one of the founders contributed 666,667 shares of his common
stock back to the Company without compensation pursuant to an agreement between
the founders.

10. STOCKHOLDERS' EQUITY (CONTINUED)
STOCK SPLITS

    In February 1998, the Company completed a one-for-two reverse stock split of
the outstanding shares of common stock. In addition, in November 1998, the
Company completed a two-for-three reverse stock split of the outstanding shares
of common stock. All share information and per share amounts in the accompanying
consolidated financial statements has been retroactively adjusted to reflect the
effect of these stock splits.

PREFERRED STOCK

    The Company is authorized to issue 5,000,000 shares of preferred stock, none
of which is issued or outstanding. The Board of Directors has the authority to
issue the preferred stock in one or more series and to fix the designations,
powers, preferences, rights, qualifications, limitations and restrictions with
respect to any series of preferred stock and to specify the number of shares of
any series of preferred stock without any further vote or action by the
stockholders.

WARRANTS

    In connection with the issuance of common stock during the year ended
December 31, 1998, the Company issued warrants to purchase a total of 314,747
shares of common stock at an exercise price of $3.33 per share. These warrants
were exercised prior to the Company's initial public offering on December 9,
1998. In November 1998, in connection with the loan agreement mentioned in Note
6, the Company issued a warrant to the lender to purchase 183,333 shares of the
Company's common stock at an exercise price equal to the initial public offering
price per share ($14.00). On January 11, 1999, the lender exercised the warrant
in a net exercise transaction and received 116,231 shares of the Company's
common stock.

NOTES RECEIVABLE FROM STOCKHOLDERS

    On June 16, 1999, in connection with its acquisition of MightyMail Networks,
Inc., the Company assumed stock subscriptions receivable from related parties in
exchange for shares of common stock. As of June 30, 1999, outstanding
subscriptions receivable amounted to approximately $995,000. All amounts mature
by April 2002 and bear interest at a rate of 5.28% per annum.

STOCK OPTION PLAN

    On November 16, 1998, the Company's Board of Directors and stockholders
approved an increase in the number of shares authorized under its 1998 stock
incentive plan (the "Plan") from 1,166,667 to 2,000,000. The Plan provides for
incentive stock options, as defined by the Internal Revenue Code, to be granted
to employees, at an exercise price not less than 100% of the fair value at the
grant date as determined by the Board of Directors. The Plan also provides for
nonqualified stock options to be issued to non-employee officers, directors and
consultants at an exercise price of not less than 85% of the fair value at the
grant date. Option vesting schedules are determined by the Board of Directors at
the time of issuance. Stock options generally vest over different periods
ranging from immediately to 25% at the end of the first year and monthly
thereafter up to a maximum of four years. Upon a change of control of the
Company, as defined in the Plan, 75% of unvested options become immediately
exercisable. Certain options' vesting can also accelerate based on the
achievement of specified performance criteria.

DEFERRED COMPENSATION

    The Company has recorded deferred compensation charges of $0, $551,000 and
$2,017,000, for the period April 16, 1996 (inception) through December 31, 1996,
and for the years ended December 31, 1997 and 1998, respectively, for the
difference between the exercise price and the deemed fair value of certain stock
options granted by the Company. These amounts are being amortized by charges to
operations, using

the accelerated method, over the vesting periods of the individual stock
options, which range from three months to four years.

    From December 1996 through June 1998, certain options were granted to
various employees which provided vesting only upon certain events, such as the
Company's successful completion of an initial public offering or individual and
Company performance goals. In June 1998 these options were modified to vest upon
the earlier of an event or two years from the date of grant. As a result, the
related compensation charge was determined in June 1998.

OPTIONS ISSUED TO CONSULTANTS

    The Company granted options to purchase 94,883 shares of common stock to
consultants at exercise prices ranging from $0.03 to $14.00 per share during the
period from January 1, 1997 through December 31, 1998. These options were
granted in exchange for consulting services performed. The Company valued these
options using the estimated fair value of the services performed which amounted
to $0, $20,000 and $246,000, for the period from April 16, 1996 (inception)
through December 31, 1996, and for the years ended December 31, 1997 and 1998,
respectively. These amounts are being amortized by charges to operations over
the respective consulting periods. The amounts charged to operations were $0,
$17,000 and $238,000, for the period from April 16, 1996 (inception) through
December 31, 1996, and for the years ended December 31, 1997 and 1998,
respectively.

1998 EMPLOYEE STOCK PURCHASE PLAN

    The Company's 1998 Employee Stock Purchase Plan was adopted by the Board of
Directors in October 1998. The Company has reserved a total of 300,000 shares of
common stock for issuance under the plan. Eligible employees may designate up to
100% of their compensation subject to certain limitations as described in the
Plan, to be deducted each pay period for the purchase of common stock at 85% of
the lesser of the fair market value of the Company's common stock on the first
day of the applicable purchasing period or the last day of the applicable
accrual period. As of December 31, 1998, no shares were issued or committed to
under this plan.

SHARES RESERVED FOR FUTURE ISSUANCE

    As of December 31, 1998, shares of common stock reserved for future issuance
were as follows:

PRO FORMA DISCLOSURE OF THE EFFECT OF STOCK-BASED COMPENSATION

    The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FAS 123 requires the use of
option valuation models that were not developed for use in valuing employee
stock

options. Pro forma information regarding net income (loss) and net income (loss)
per share is required by FAS 123. This information is required to be determined
as if the Company has accounted for its employee stock options under the fair
value method of FAS 123. Under this method, the estimated fair value of the
options is amortized to expense over the options' vesting period. The fair value
for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions:

</TABLE>

    Because FAS 123 is applicable only to options granted since inception, its
adjusted effect will not be fully reflected until the year 2000.

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions, including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimates, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

    The weighted-average fair value of options granted to employees during the
period from April 16, 1996 (inception) through December 31, 1996, and during the
years ended December 31, 1997 and 1998, were $.02, $0.36 and $8.01,
respectively.

    The effect of applying the FAS 123 fair value method to the Company's
stock-based awards results in net loss and net loss per share as follows:

11. RETIREMENT PLAN

    On March 26, 1998, the Company established a 401(k) Profit Sharing Plan (the
"Plan") available to all employees who meet the Plan's eligibility requirements.
Employees may elect to contribute from 1% to 25% of their eligible earnings to
the Plan subject to certain limitations. This defined contribution plan provides
that the Company may, at its discretion, make contributions to the Plan on a
periodic basis. The Company has not made contributions to the Plan.

re-branded as SnapTV. Xoom.com will become the direct electronic commerce
partner for SnapTV, managing the customer database, e-mail marketing and other
sales efforts. Direct online shopping offers will include Xoom.com products and
services, as well as SnapTV merchandise. ValueVision and Xoom.com will share
revenues from all such initiatives. As part of the agreements, ValueVision and
Xoom.com entered into a warrant purchase agreement whereby Xoom.com agreed to
purchase a warrant for 404,760 shares of ValueVision common stock at an exercise
price of $24.71 per share, and ValueVision agreed to purchase a warrant for
244,004 shares of Xoom.com common stock at an exercise price of $40.89 per

contemplated in the merger agreement do not occur by December 31, 1999, the
warrants shall terminate. These rights and obligations of Xoom.com and SNAP will
be assigned to and assumed by NBC Internet, Inc. following consummation of the
transactions contemplated in the merger agreement.

    On October 4, 1999, John G. Balletto ("Balletto") filed a lawsuit against
Xoom.com in September 1999 in the San Francisco Superior Court alleging breach
of contract and specific performance. Balletto has alleged that in connection
with a loan which Xoom.com obtained from Sand Hill Capital LLC in 1998 and
pursuant to an oral contract with Xoom.com, Balletto is entitled to a finder's
fee. Balletto has sought specific performance of the alleged oral agreement by
having the court direct Xoom.com to issue 33,784 shares of Common Stock to
Balletto and such other relief that the Court may deem just and proper. Xoom.com
believes that this lawsuit is without merit and intends to defend the suit
vigorously. Xoom.com does not believe that the outcome of this matter will
materially adversely impact its results of operations, cash flows, or financial
position. However, depending on the amount and timing, an unfavorable resolution
could have a material adverse effect on Xoom.com's results of operations,
financial position or cash flows in a particular period.

                     (A DELAWARE LIMITED LIABILITY COMPANY)

                         NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1997 AND 1998

                   (INFORMATION AS OF AND FOR THE SIX MONTHS
                   ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)

(1) ORGANIZATION AND BASIS OF PRESENTATION

    (A) THE COMPANY

    Snap! LLC (Snap or the Company) commenced operations in December 1996 (the
Company had no significant operating results during 1996) and was introduced as
a service in September 1997. Snap is an Internet portal service company that
offers a branded network of comprehensive information, media, ecommerce,
communication, and navigation services to millions of users daily.

    The Company was incorporated on June 25, 1998 as a Delaware limited
liability company (LLC). Prior to that date, the Company was operated as a
wholly-owned and consolidated operation of CNET, Inc. (CNET). The accompanying
financial statements retroactively reflect the incorporation of the Company as
an LLC to the date of the inception of the Company's operations. On or about
June 30, 1998, as part of a contribution agreement entered into between CNET and
NBC, Inc. (NBC) (collectively, the Members), CNET contributed its assets and
liabilities used exclusively in the operation of the Snap service to the LLC for
an approximately 81% ownership interest, while NBC contributed approximately
$5.9 million in cash to the LLC for an approximately 19% ownership interest (see
Note 7). CNET's and NBC's contributions were recorded at their respective
historical carrying amounts.

    The accompanying financial statements and related notes also reflect the
historical results of operations and cash flows of Snap while it was operated by
CNET. The statement of operations includes all revenues and costs directly
attributable to Snap, including costs for facilities, functions and services
used by the business and allocations of costs for certain administrative
functions and services performed by centralized departments of CNET. Costs have
been allocated to the Snap operation based on CNET management's estimate of
costs attributable to the Snap operation. Such costs are not necessarily
indicative of the costs that would have been incurred if Snap had been a
separate entity.

    (B) LIQUIDITY

    The Company has sustained losses and negative cash flows from operations
since inception and expects these conditions to continue into the foreseeable
future. As of June 30, 1999, the Company had accumulated losses from inception
of approximately $101 million. The implementation of the Company's business plan
is dependent upon obtaining additional equity or debt financing through public
or private financing, strategic partnerships or other arrangements. There can be
no assurance that such additional financing will be available on terms
attractive to the Company, or at all. Should additional external financing not
be available, management would curtail the Company's current growth plans to
enable the Company to continue operations through 1999.

    (C) XOOM/NBC/SNAP MERGER

    On May 9, 1999, the Company, Xoom.com, Inc., NBC, Inc. and certain of its
affiliates (collectively, NBC), and CNET, Inc. 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 the Company,

Xoom.com, Inc., and certain of NBC's Internet assets (including NBC.com,
Videoseeker.com and NBC Interactive Neighborhood) and a 10% interest in
CNBC.com.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (A) REVENUE RECOGNITION

    The Company's revenues are derived principally from the sale of banner
advertisements and sponsorships. Advertising revenues are recognized in the
period which the advertisement is displayed, provided that no significant
obligations remain at the end of the period. Company obligations typically
include the guarantee of a minimum number of "impressions" or times that an
advertisement appears in pages viewed by users of the Company's online
properties. To the extent the minimum guaranteed impressions are not delivered,
the Company defers recognition of the corresponding revenue until the remaining
guaranteed impression levels are achieved.

    The Company also earns revenue on sponsorship contracts from fees relating
to the design, coordination, and integration of customers' content and links
into Snap's online media properties. Such developmental fees are recognized as
revenue once the related activities have been performed and the customers' Web
links are available on Snap's online properties. Snap also derives revenues from
development fees and electronic commerce which to date have each comprised less
than 10% of revenues.

    Deferred revenue is primarily comprised of billings in excess of recognized
revenue relating to advertising contracts and payments received pursuant to
sponsorship agreements in advance of revenue recognition.

    (B) PRODUCT DEVELOPMENT

    Development expenses include expenses which were incurred in the development
of new or improved technologies that enhance the performance of the Company's
Internet service. Costs for development are expensed as incurred. Costs related
to specific products or services are no longer recognized as development
expenses when the specific product or service is launched and incorporated into
the Company's internet service.

    (C) ADVERTISING COSTS

    All advertising costs are expensed when incurred. Advertising expense,
including the value of advertising provided through barter transactions, totaled
approximately $1,007,000, $18,559,000, $986,000 and $28,367,000 for the years
ended December 31, 1997 and 1998, and the six months ended June 30, 1998 and
1999, respectively. These costs include the value of promotion and advertising
provided by NBC (see Note 7).

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                   (INFORMATION AS OF AND FOR THE SIX MONTHS

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (D) CONCENTRATIONS OF CUSTOMERS AND CREDIT RISK

    One customer comprised 8% and 29% of net revenues for the year ended
December 31, 1998 and the six-months ended June 30, 1999, respectively, in
conjunction with non-monetary transactions in which the Company received equity
as consideration for services sold by the Company. One separate customer
accounted for 18% of net revenues for the year ended December 31, 1997. During
the years ended December 31, 1997 and 1998, and the six months ended June 30,
1998 and 1999 no other customer accounted for greater than 10% of revenues.

    During the quarter ended June 30, 1999, the Company received stock in a
private company currently valued at approximately $10 million in exchange for
future services of equivalent value to be rendered by the Company. Subsequent to
the fiscal quarter end, the Company and the private company issuer of the stock
completed an escrow arrangement under which the Company would earn the release
of the shares from escrow. The release of the shares from escrow would be based
on the Company's actual monthly performance during a two-year term. As of June
30, 1999, the Company had earned the release of shares valued at approximately
$200,000, which has been recorded as revenue in the quarter then ended.

    No other significant revenues were recorded on non-monetary transactions in
which the Company received equity investments as consideration for services.

    Financial instruments which potentially expose the Company to a
concentration of credit risk consists primarily of trade accounts receivable.
Accounts receivable are typically unsecured and are derived from revenues earned
from customers primarily in the United States. The Company performs ongoing
credit evaluations of its customers and maintains reserves for potential credit
losses. At December 31, 1998 and June 30, 1999, no one customer accounted for
more than 10% of the accounts receivable balance.

    (E) CASH, CASH EQUIVALENTS, AND INVESTMENTS

    The Company considers investments in highly liquid instruments purchased
with remaining maturities of 90 days or less to be cash equivalents. Cash
equivalents are recorded at cost which approximates fair value. The Company
maintains its cash in two depository accounts with high credit quality financial
institutions.

    Equity investments in private companies are recorded initially at fair value
when the Company's rights of ownership vest, and subsequently are carried at the
lower of cost or net realizable value. Equity investments in publicly traded
companies are initially recorded at market value when the Company's rights of
ownership vest and are assumed to be available-for-sale securities which are
carried at market value, with changes in market value recorded as unrealized
gains and losses in total member's equity.

    (F) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method over the
estimated useful lives of the assets, generally three

                   ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
to seven years. Property and equipment recorded under leasehold improvements are
amortized on a straight-line basis over the shorter of the lease terms or their
estimated useful lives.

    (G) INCOME TAXES

    Prior to June 25, 1998 the Company's taxable losses were included in the
consolidated tax returns of CNET, Inc. The Company did not receive any benefit
from CNET Inc.'s receipt of such operating losses or research and development
credits.

    Upon the incorporation as a Delaware limited liability company on June 26,
1998, the Company's net operating losses inured to the benefit of the Members.
Accordingly, no provision for income taxes is recognized in the accompanying
financial statements as the net loss generated from the Company's operations was
"passed through" to the Members.

    (H) SOFTWARE DEVELOPMENT COSTS

    Statement of Financial Accounting Standard (SFAS) No. 86, ACCOUNTING FOR THE
COSTS OF COMPUTER SOFTWARE TO BE SOLD, LEASED OR OTHERWISE MARKETED, governs
accounting for software development costs. This statement provides for
capitalization of certain software development costs once technological
feasibility has been established. The costs capitalized are then amortized on a
straight-line basis over the estimated product life, or on the ratio of current
revenue to total projected product revenues, whichever is greater. No such costs
have been capitalized to date.

    (I) STOCK-BASED COMPENSATION

    The Company accounts for its stock-based employee compensation plans using
the intrinsic value method. As such, compensation expense is recorded on the
date of grant if the current market price of the underlying membership unit
exceeded the exercise price.

    (J) USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. Actual results could differ from those estimates.

    (K) COMPREHENSIVE LOSS

    The Company has adopted the provisions of SFAS No. 130, REPORTING
COMPREHENSIVE INCOME, which established standards for reporting and disclosures
of comprehensive results and its components (revenues, expenses, gains and
losses) in a full set of general purpose financial statements. During the second
quarter of 1999 the Company reported unrealized holding gains arising from
investments classified as available-for-sale. The Company has an investment in
Mail.com, Inc. (Mail.com), which completed an initial public offering during the
second quarter of 1999. The Company's investment in Mail.com was

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
recorded at market value based on the closing price of the stock on June 30,
1999, and the increase in value of the stock was recorded as an unrealized
holding gain in comprehensive loss.

    (L) BARTER TRANSACTIONS

    The Company trades advertisements on its online properties in exchange for
advertisements on the online properties of other companies. These revenues and
marketing expenses are recorded at the fair value of services provided or the
fair value of the services received, whichever is more reliably determinable in
the circumstances. Revenue from barter transactions is recognized as income when
advertisements are delivered on the Company's online properties. Expense from
barter transactions is recognized when advertisements are provided to the
Company. Barter revenues and expenses were approximately $342,000, $636,000,
$473,000 and $896,000 for the years ended December 31, 1997 and 1998 and for the
six months ended June 30, 1998 and 1999, respectively.

    (M) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying value of the Company's cash and cash equivalents, accounts
receivable, equity investments, accounts payable and long-term debt approximate
their respective fair values.

    (N) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF

    The Company reviews its long-lived assets and certain identifiable
intangibles whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured as
the amount by which the carrying amount of the assets exceeds the fair value of
the assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell.

    (O) RECENT ACCOUNTING PRONOUNCEMENTS

    The FASB recently issued SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS
AND HEDGING ACTIVITIES. SFAS No. 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts (collectively referred to as derivatives), and for
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. For a derivative not designated as a hedging
instrument, changes in the fair value of the derivative are recognized in
earnings in the period of change. The Company must adopt SFAS No. 133 by January
1, 2001. Management does not believe the adoption of SFAS No. 133 will have a
material effect on the financial position or operations of the Company.

(5) CREDIT FACILITIES AND COMMITMENTS

    (A) LINE OF CREDIT

    As of December 31, 1998, the Company has a revolving line of credit for
$27,000,000 which is secured by substantially all of the Company's assets,
guaranteed by General Electric, parent company of the Company's principal
shareholders, and bears interest at various rates which ranged from 5.40% to
6.86% during the year ended December 31, 1998. Extensions of credit are
available until June 15, 2001. Advances made under the facility shall mature no
later than July 15, 2001. At December 31, 1998, $13,500,000 was outstanding and
$10,170,000 was available under the line of credit. The outstanding balance is
comprised of multiple individual borrowings, which are due between April 6, 1999
and June 28, 1999. The borrowings are classified as long-term on the face of the
balance sheet because the Company has the ability and intent to extend the due
dates beyond December 31, 1999.

    On June 25, 1999, the Company's revolving line of credit, guaranteed by
General Electric, was increased to $45,000,000. At June 30, 1999, $30,100,000
was outstanding and $11,220,000 was available under the line of credit. The
outstanding balance is comprised of multiple individual borrowings, due between
July 6, 1999, and December 7, 1999, and bear interest at various rates ranging
from 5.22% to 8.25%. These borrowings are classified as long-term on the face of
the balance sheet because the Company has the ability and intent to extend the
due dates beyond twelve months.

    In both periods, a total of $3,330,000 of the line of credit was reserved in
accordance with the requirements of the Company's facilities lease.

    (B) COMMITMENTS

    Such allocations are not necessarily indicative of the costs that would have
been incurred if the Company had been a separate entity. However, management
believes the differences between the allocated costs and the cost to obtain such
services from an outside third party would not be significant.

    Following June 30, 1998, the Company began direct procurement and payment of
all of its expenses, with the exception of certain services it contracted with
CNET to provide or maintain. Such services include creative services, human
resources, accounting, facilities, technology support, bandwidth and hosting
support, and sales and marketing, and the Company recorded expenses totaling
$3.7 million and $3.9 million for the year ended December 31, 1998 and for the
six months ended June 30, 1999, respectively, for amounts due to CNET for such
services.

    NBC has provided certain promotional and other services to the Company since
its investment date. NBC has provided advertising and promotion services to the
Company which have been recorded as capital contributions at the time the
services were provided based on the average CPM value for commercial air time
during the period the services were provided. The Company has recorded

and promotion expenses of approximately $14.1 million and $26.0 million for the
year ended December 31, 1998 and the six months ended June 30, 1999,
respectively, at the average CPM value for commercial air time during the period
the services were provided. NBC is not committed to provide such services to the
Company. NBC has provided other services to the Company related to advertising
production and legal support and the Company has recorded expenses totaling $0.2
million and $1.4 million for the year ended December 31, 1998 and for the six
months ended June 30, 1999, respectively, for amounts due to NBC for such
services.

    During the years ended December 31, 1997 and 1998 and the six months ended
June 30, 1998 and 1999, the Company has recorded no significant revenues from
CNET, General Electric, NBC or any of their affiliates.

    The Company's credit facility is guaranteed by General Electric, parent
company of NBC (see Note 5).

    As defined in the contribution agreement, NBC has an option to purchase
14,805,556 membership units for an aggregate price of $31,365,802. The option
expires in June, 2001.

(8) DEFINED CONTRIBUTION PLAN

    The Company has a defined contribution plan pursuant to Section 401(k) of
the Internal Revenue Code covering all eligible employees. Under the plan,
participating employees may defer a portion of their pretax earnings up to the
Internal Revenue Service annual contribution limit. For the year ended December
31, 1998, the Company did not contribute to the plan.

(9) SEGMENT INFORMATION

    The Company has adopted the provisions of SFAS No. 131, DISCLOSURE ABOUT
SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. SFAS No. 131 establishes
standards for the reporting by public business enterprises of information about
operating segments, products and services, geographic areas and major customers.
The method for determining what information to report is based on the way that
management organizes the operating segments within the Company for making
operating decisions and assessing financial performance.

    The Company's chief operating decision maker is considered to be the
Company's Chief Executive Officer ("CEO"). The information reviewed by the CEO
for purposes of making operating decisions and assessing financial performance
is identical to the information presented in the accompanying financial
statement of operations. The Company operates in one segment, Internet
operations. The Company has had no international revenues to date.

(10) LEGAL PROCEEDINGS

    The Company was involved in a dispute with SNAP Technologies, Inc. (SNAP
Tech) which claimed to own the SNAP trademark. SNAP Tech filed a lawsuit against
CNET on November 19, 1998, alleging trademark infringement and related statutory
violations, to which the Company filed an answer on November 24, 1998. On July
15, 1999, the lawsuit with SNAP Tech was settled. Pursuant to the settlement

agreement, the Company shall pay $200,000, grant an advertising credit of
$1,000,000, and provide certain other promotions to SNAP Tech in exchange for
all worldwide rights to all names, trademarks, and service marks previously used
by SNAP Tech. NBC and CNET will indemnify the Company for this legal settlement.
Accordingly, no amounts related to this settlement have been accrued in the
accompanying financial statements.

    In March 1999 the Company filed a complaint against CityAuction, Inc. in
connection with an agreement entered into between the Company and CityAuction to
promote CityAuction's online auction site in exchange for monetary compensation
and warrants to purchase shares of CityAuction. The Company is claiming that
CityAuction breached the agreement by refusing to honor the Company's exercise
in February 1999 of its CityAuction warrants, failing to make a $125,000 payment
due to the Company and failing to provide the Company with notice of
CityAuction's pending acquisition by Ticketmaster Online-CitySearch, Inc. The
Company is also claiming that Ticketmaster induced CityAuction to breach it
contractual obligations to the Company. This matter is in the discovery stage.
An unfavorable outcome in this litigation would deny the Company the economic
benefit of the claimed payments and stock ownership of CityAuction. No amounts
contingent upon a favorable outcome in this litigation have been recorded in the
Company's financial statements.

The Board of Directors
National Broadcasting Company, Inc.

    We have audited the accompanying combined balance sheets of NBC Multimedia
Division as of December 31, 1997 and 1998, and the related combined statements
of operations and changes in parent company's investment and net advances and
cash flows for the years then ended. These combined financial statements are the
responsibility of NBC Multimedia Division's management. Our responsibility is to
express an opinion on these combined financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of NBC Multimedia
Division as of December 31, 1997 and 1998, and the results of its operations and
its cash flows for the years then ended in conformity with generally accepted
accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

                           DECEMBER 31, 1997 AND 1998

                (INFORMATION AS OF AND FOR THE SIX MONTHS ENDED
                      JUNE 30, 1998 AND 1999 IS UNAUDITED)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

    (A) SUMMARY OF OPERATIONS

    The accompanying combined financial statements include the assets and
operations of NBC.com, NBC Interactive Neighborhood (NBC-IN) and VideoSeeker
(collectively, the Division), all of which are operating divisions of NBC
Multimedia, Inc., a wholly owned subsidiary of National Broadcasting Company,
Inc. (NBC), which is a wholly owned subsidiary of General Electric Company (GE).
NBC has agreed to merge the operations and certain defined net assets of the
NBC.com and NBC-IN divisions with Xoom.com, Inc. (Xoom), under an agreement
dated May 9, 1999 and amended on June 11, 1999, which also provides that NBC
will contribute its ownership interests in SNAP! LLC to the merged entity, NBC
Internet, Inc. (NBCi). Upon completion of these transactions, NBC will own
approximately 48.5% of the common stock of NBCi. In addition, NBC will purchase
from NBCi zero coupon convertible subordinated debentures due 2006 with an
aggregate principal amount at maturity of approximately $487 million in exchange
for the net assets of VideoSeeker and a note payable in the amount of $340
million.

    The principal activities of the Division are as follows:

    NBC.com, launched in August 1995, is the Internet venue for the NBC
television network offering content about NBC on-air programming, providing show
descriptions, episode updates, actor biographies, schedule information and
program trivia for NBC entertainment programming. NBC.com also maintains direct
links to NBC's news, finance and sports sources, MSNBC News, CNBC, and MSNBC
Sports, as well as links to local news and weather through NBC's local station
affiliates via NBC-IN.

    NBC-IN, launched in October 1997, is a Web-based network of local news and
information sites developed with certain participating NBC owned and affiliated
television stations throughout the United States. Through NBC-IN.com, Internet
users can access local news, sports and weather as well as services such as job
search, local advertising for real estate and automobiles, restaurant reviews
and telephone directories.

    VideoSeeker, launched in May 1998, is a full-service video aggregator,
licensing content from NBC's media properties as well as from third parties to
offer users free online access to topical and archival news video from MSNBC,
clips from NBC television programming, movie trailers, music video and
interviews.

    The Division generates revenues primarily through advertising, sponsorship
and licensing agreements.

    (B) BASIS OF PRESENTATION

    The accompanying combined financial statements include certain corporate
general and administrative expenses incurred on a consolidated basis by NBC for
all periods presented that have been allocated to the Division. Such allocations
are included in general and administrative expenses in the Division's combined
statements of operations and changes in parent company's investment and net
advances. In management's opinion, the basis for the allocation of such costs is
reasonable and is based upon the ratio of the total direct operating costs
incurred by the Division to total NBC direct operating costs. However, the
expenses allocated to the Division, although made on a basis management believes
to be reasonable, may not necessarily be representative of what the Division
would have incurred on a stand-alone basis.

</TABLE>

    NBC corporate overhead expenses consist primarily of senior management
salaries and benefits, financial, legal, information technology, and other
administrative costs.

    (C) USE OF ESTIMATES

    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the combined
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.

    (D) REVENUE RECOGNITION

    The Division derives revenue from the sale of banner advertisements under
short-term contracts. To date, the duration of the Division's advertising
commitments has generally averaged from one to six months. Advertising revenues
are recognized ratably in the period in which the advertisement is displayed,
provided that no significant Division obligations remain and collection of the
resulting receivable is probable. Division obligations typically include the
guarantee of a minimum number of "impressions" or times that an advertisement
appears in pages viewed by the users of the Division's websites. To the extent
minimum guaranteed impressions are not met, the Division defers recognition of
the corresponding revenue until the remaining guaranteed impression levels are
achieved.

    The Division (primarily through NBC-IN) also derives revenues from license
fees from various service providers who pay a fee to furnish content, e-commerce
or services in a particular category of the Division's websites. These fees are
deferred and recognized ratably over the term of the related agreement, which is
generally two to three years.

    The Division also earns revenue on sponsorship contracts for fees relating
to the design, coordination and integration of the customer's contents and links
to the Division's websites. These development fees are recognized as revenue
once the related activities have been performed. Revenues from electronic
commerce revenue sharing arrangements within the Division's websites are
recognized upon notification from its partners of sales attributable to the
Division's site, and were insignificant in all periods presented.

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)

                           DECEMBER 31, 1997 AND 1998

                (INFORMATION AS OF AND FOR THE SIX MONTHS ENDED
                      JUNE 30, 1998 AND 1999 IS UNAUDITED)

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The Division receives equity instruments (common or preferred stock, options
and warrants) under certain agreements with service providers and under certain
outsourcing agreements. When the measurement date for such equity instruments is
fixed and there is a sufficient disincentive to breach the contract in
accordance with Emerging Issues Task Force Abstract No. 96-18, "Accounting for
Equity Instruments That are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services," the Division records the receipt
of the equity instruments and corresponding deferred revenue. When equity
instruments are contingent upon the achievement of certain targets, the Company
records the benefit of the equity instruments at the time the targets are
achieved at the then fair market value of the equity instrument. Such amounts
are amortized ratably to revenue over the length of the contract commencing on
the measurement date.

    Such equity instruments are transferred to NBC and upon measurement are
charged to Parent company's investment and net advances. Changes in value
subsequent to the measurement date are not reflected in the Division's combined
financial statements.

    Revenues recognized under agreements whereby the Division receives equity
instruments in the service provider's stock as described above, in consideration
for the advertising and customer acquisition opportunities, are recorded as
Advertising, sponsorship, and license fee revenue and aggregated $33,305,
$1,408,595, $263,339, and $2,163,037 in the years ended December 31, 1997, and
1998, and the six months ended June 30, 1998 and 1999, respectively.

    Revenue from the receipt of equity instruments in connection with
outsourcing agreements, recorded as Other revenue, aggregated $--0-, $3,693,300,
$1,537,094, and $4,122,217 in the years ended December 31, 1997 and 1998, and
the six months ended June 30, 1998 and 1999, respectively.

    (E) BARTER TRANSACTIONS

    The Division trades advertisements on its Web properties in exchange for the
loan of computer equipment. Barter revenues and expenses are recorded at the
fair market value of services provided or received, whichever is more
determinable in the circumstances. Revenue from barter transactions is
recognized as income when advertisements are delivered on the Division's
websites. Barter expense is recognized over the period the equipment is in use,
which is typically in the same period when the barter revenue is recognized.
Advertising barter revenues and expenses were approximately $393,000, $77,000,
$74,500 and $--0- for the years ended December 31, 1997 and 1998, and the six
months ended June 30, 1998 and 1999, respectively.

    (F) PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the related assets,
generally five to seven years. Leasehold improvements are amortized using the
straight-line method over the estimated useful lives of the assets or the term
of the leases, whichever is shorter.

                           DECEMBER 31, 1997 AND 1998

                (INFORMATION AS OF AND FOR THE SIX MONTHS ENDED

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (G) INCOME TAXES

    For all periods, the Division has been included in the consolidated federal,
state and local income tax returns of NBC. Income taxes are calculated and
provided for on a consolidated basis, and the Division has not been allocated
any income tax expense (benefit) by NBC. For purposes of these financial
statements, federal, state and local income taxes are provided as if the
Division had filed a separate return on a stand-alone basis for all periods
presented.

    The Division accounts for income taxes using the asset and liability method.
Under this method, deferred tax assets and liabilities are recognized, to the
extent realizable, for the future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax bases and operating loss and tax credit
carryforwards. Deferred tax assets and liabilities are measured using enacted
tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
results of operations in the period that the tax change occurs. Such tax assets
and liabilities are not a part of the merger transaction. Accordingly, all
current and deferred tax assets and liabilities are included as part of Parent
Company's investment and net advances, and are not reflected in the combined
balance sheets of the Division.

    (H) IMPAIRMENT OF LONG-LIVED ASSETS

    The Division reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets.

    (I) ADVERTISING EXPENSES

    The Division expenses the cost of advertising and promoting its services as
incurred. Such costs are included in sales and marketing on the combined
statements of operations and totaled $425,166, $2,569,844, $1,077,008 and
$164,187 for the years ended December 31, 1997 and 1998 and the six months ended
June 30, 1998 and 1999, respectively. These costs include the value of
advertising provided by NBC of $0, $2,015,400, $791,500, and $0 for the years
ended December 31, 1997 and 1998 and the six months ended June 30, 1998 and
1999, respectively, which have been recorded based on average values for
commercial air time sold by NBC during the period the services were provided.

    (J) PRODUCT DEVELOPMENT COSTS

    Product development costs consist principally of salaries and related costs,
and are charged to expense as incurred.

(1) SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

    (K) FINANCIAL INSTRUMENTS AND CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Division to significant
concentrations of credit risk consist of accounts receivable and accounts
payable. At December 31, 1997 and 1998, the fair value of these instruments
approximated their financial statement carrying amount because of the short-term
maturity of these instruments. The Division has not experienced any significant
credit loss to date. Revenue from the Division's five largest customers
accounted for approximately 53% and 27% of the Division's advertising,
sponsorship and license fee revenue for the years ended December 31, 1997 and
1998, respectively.

    No single customer exceeded 10% of the Division's advertising, sponsorship
and license fee revenue for the year ended December 31, 1998. Two customers
accounted for 42% of the Division's accounts receivable at December 31, 1998.

    Three customers exceeded 10% of revenue for the year ended December 31,
1997. Three customers accounted for approximately 74% of accounts receivable at
December 31, 1997.

    (L) COMPREHENSIVE INCOME (LOSS)

    There were no differences between the Division's comprehensive loss and its
net loss as reported.

    (M) SEGMENT INFORMATION

    The Division operates in a single segment in the United States.

    (N) RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and for hedging activities. SFAS No. 133 is
effective for all fiscal quarters of fiscal years beginning after June 15, 2000.
The Division has not yet determined the impact of adopting SFAS No. 133.

    (O) INTERIM RESULTS

    The accompanying interim combined financial statements as of June 30, 1999
and for the six months ended June 30, 1998 and 1999 are unaudited. In the
opinion of management, the unaudited interim financial statements have been
prepared on the same basis as the annual financial statements and reflect all
adjustments, which include only normal recurring adjustments, necessary to
present fairly the financial position as of June 30, 1999 and the results of the
Division's operations and its cash flows for the six months ended June 30, 1998
and 1999. The financial data and other information disclosed in these notes to
combined financial statements related to these periods are unaudited. The
results for the six months ended June 30, 1999 are not necessarily indicative of
the results to be expected for the year ending December 31, 1999.

</TABLE>

(3) INCOME TAXES

    The Division has generated net losses for all periods through December 31,
1998, and has no net income tax expense in any period on a stand-alone basis.
Although no net deferred tax assets with respect to net operating loss benefits
would have been established due to uncertainty of utilization, net operating
loss benefits would have been available to offset net income in the six months
ended June 30, 1999 on a stand-alone basis. Other deferred tax assets
aggregating approximately $3.2 million and $5.2 million at December 31, 1997 and
1998, respectively, arising principally from temporary differences in the
recognition of revenue related to equity instruments also would have been offset
by a valuation allowance on a stand-alone basis.

(4) PARENT COMPANY'S INVESTMENT AND NET ADVANCES

    Operations are funded through advances from NBC. Such advances have no
defined repayment terms.

    During the years ended December 31, 1997 and 1998, and the six months ended
June 30, 1998 and 1999, respectively, net advances were reduced by $266,442,
$18,112,601, $14,973,691, and $12,420,060, representing the value of equity
instruments received under partner agreements by the Division and transferred to
NBC.

(5) OUTSOURCING AGREEMENTS

    In May 1998, the Division entered into a four year strategic alliance with
USWeb whereby USWeb would perform production and hosting services for the
Division's Web sites. The Division is committed to pay approximately $2.6
million per year for these services under the agreement. NBC has the right to
extend the agreement unilaterally for an additional four-year term at a fixed
increase in the annual fee.

                (INFORMATION AS OF AND FOR THE SIX MONTHS ENDED
                      JUNE 30, 1998 AND 1999 IS UNAUDITED)

(5) OUTSOURCING AGREEMENTS (CONTINUED)
NBC may terminate the agreement with three months prior written notice to USWeb.
Beginning in November 1999, USWeb may terminate the agreement with six months
prior written notice to NBC. In connection with the strategic alliance, USWeb
issued warrants to the Division to purchase 1,600,000 and 500,000 shares of
USWeb Common Stock at $22.14 and $25.03 per share, respectively. If the
agreement had been cancelled by the Division before May 1999, USWeb could have
cancelled the warrants to purchase 1,050,000 shares or, if the warrants had been
previously exercised, could have repurchased them.

    In October 1997, NBC signed a two year strategic alliance agreement with
InterVU, Inc. ("InterVU") whereby InterVU is the exclusive provider, subject to
certain limitations, of technology and services for VideoSeeker. In exchange for
entering into the agreement, InterVU issued 1,280,000 shares of series G
preferred stock to the Division. In addition, InterVU agreed to pay the Division
$2 million in a series of non-refundable payments for promotional value and the
cost of producing and operating VideoSeeker, which is recognized as Other
revenue ratably over the two-year period.

    In March 1999, NBC-IN entered into an exclusive three-year agreement under
which 24/7 Media, Inc. will sell advertising on participating NBC television
stations and their associated websites. As part of the agreement, 24/7 Media,
Inc. issued to the Division warrants to purchase up to 150,000 shares of 24/7
Media, Inc.'s common stock for $26.05 per share. These warrants vest and expire
on specified dates and in specified amounts between March 11, 1999 and March 11,
2002. The value of the warrants received is recorded on each vesting date at the
then fair market value and recognized as Other revenue ratably over the term of
the agreement.

These agreements are accounted for as described in note 1(d).

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders

Paralogic Corporation

    We have audited the accompanying balance sheets of Paralogic Corporation as
of December 31, 1996 and 1997, and the related statements of operations,
shareholders' equity (deficit) and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Paralogic Corporation at
December 31, 1996 and 1997, and the results of its operations and its cash flows
for years then ended, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY

    Paralogic Corporation (the "Company"), was incorporated in the State of
California on January 12, 1995.

    The Company is a provider of chat room software and various online services.

    BASIS OF PRESENTATION

    The Company has negative working capital and an accumulated deficit at
December 31, 1997. The accompanying financial statements have been prepared
assuming that the Company will continue as a going concern. On March 11, 1998,
the Company agreed to be acquired by Xoom.com, Inc.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported results of operations during the reporting period.
Actual results could differ from those estimates.

    CASH

    The Company maintains cash in depository accounts with two financial
institutions.

    CONCENTRATIONS OF CREDIT RISK

    The Company conducts business primarily with companies throughout the United
States. Management believes that any risk of accounting loss is mitigated by the
Company's ongoing credit evaluations of its customers. The Company generally
does not require collateral. The Company analyzes the need for reserves for
potential credit losses and records reserves when necessary.

    For the year ended December 31, 1996, four customers accounted for $41,000,
$35,320, $29,625 and $28,000 or 24%, 20%, 17% and 16% of net revenue; of these,
one customer owed the Company $8,020 at December 31, 1996. There was no single
customer that accounted for more than 10% of net revenue for the year ended
December 31, 1997.

    FIXED ASSETS

    Fixed assets are recorded at cost, less accumulated depreciation.
Depreciation is computed using the straight-line method over the estimated
useful lives of three years.

    REVENUE RECOGNITION

       SERVICE

        The majority of the Company's service revenue is from fees related to
    fees charged for chat network hosting and are recognized when the services
    are performed.

                             PARALOGIC CORPORATION

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
       LICENSE FEES

        The Company licenses software under non-cancelable license agreements to
    end-users. License fee revenue is recognized when a non-cancelable license
    agreement has been signed, the product has been delivered, there are no
    uncertainties surrounding product acceptance, the fees are fixed and
    determinable, collection is considered probable and all significant
    contractual obligations have been satisfied.

       ADVERTISING

        Advertising revenue are derived from the sale of banner advertisements
    under short-term contracts. Advertising revenue on banner contracts are
    recognized ratably in the period in which the advertisement is displayed,
    provided that no significant Company obligations remain and collection of
    the resulting receivable is probable. Company obligations typically include
    the guarantee of a minimum number of "impressions" or times that an
    advertisement appears in pages viewed by the users of the Company's online
    properties. To the extent minimum guaranteed impressions are not met, the
    Company defers recognition of the corresponding revenue until the remaining
    guaranteed impression levels are achieved.

    ADVERTISING EXPENSE

    All advertising costs are expensed when incurred. Advertising costs which
are included in sales and marketing expense for the years ended December 31,
1996 and 1997 were $0 and $9,377, respectively.

    INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"), which requires the use of the liability method in accounting for income
taxes. Under FAS 109, deferred tax assets and liabilities are measured based on
differences between the financial reporting and tax bases of assets and
liabilities using enacted tax rates and laws that are expected to be in effect
when the differences are expected to reverse.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" ("FAS 130"), and Statement No. 131,
"Disclosure about Segments of an Enterprise and Related Information" ("FAS
131"). The Company is required to adopt these statements in fiscal year 1998.
FAS 130 establishes new standards for reporting and displaying comprehensive
income and its components. FAS 131 requires disclosure of certain information
regarding operating segments, products and services, geographic areas of
operation and major customers. Adoption of these statements is expected to have
no impact on the Company's consolidated financial position, results of
operations or cash flows.

    The valuation allowance increased by $89,586 in 1997.

4. SHAREHOLDERS' EQUITY (DEFICIT)

    The Company is authorized to issue 1,000,000 shares of common stock, with a
par value of $1.00 per share.

    During 1997, the Company issued shares of common stock to consultants in
exchange for consulting services. The Company valued the common stock using the
estimated fair value of the services performed which amounted to $6,000. This
amount was amortized by charges to operations over the consulting period.

5. COMMITMENTS AND CONTINGENCIES

    LEASE COMMITMENTS

    The Company has entered into certain operating leases for office space. At
December 31, 1997, the Company had no future commitments for noncancelable
operating leases.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

5. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    The Company's rental expense under operating leases for the years ended
December 31, 1996 and 1997 totaled $300 and $3,900, respectively.

    CONTINGENCY ACCRUAL

    Due to the nature of its business, Paralogic Corporation is subject to
various threatened or filed legal actions. At December 31, 1997, there were
certain legal proceedings pending against the Company. These legal disputes were
settled in 1998 in connection with the business combination which is described
in Note 6. The settlement consisted of an issuance to the plaintiff of 71,343
shares of the acquiror's common stock, valued at approximately $164,802. This
settlement amount associated with this dispute was accrued for at December 31,
1997.

6. SUBSEQUENT EVENTS

    In March 1998, the Company spun off certain components of the business into
a new company named Paralogic Software, Inc. ("PSI"). The shareholders of the
Company retained the same ownership privileges and rights in PSI as were in
effect for the Company at the time of the spin off. PSI retained the Company's
advertising and services businesses as well as the ownership of the Paralogic
chat technology. The Company retained a perpetual right to use and license the
Paralogic chat technology and all of the tangible assets and liabilities.

    Effective March 11, 1998, the Company entered into merger agreement with
Xoom.com, Inc. under which the outstanding shares of common stock of the Company
were exchanged for common shares of Xoom.com, Inc. and the right to receive
certain cash distributions from Xoom.com, Inc. The financial statements do not
include any adjustments to the recorded amounts of assets and liabilities which
may result from this transaction.

7. IMPACT OF YEAR 2000 (UNAUDITED)

    The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

    The Company believes that it will not be required to modify or replace any
portion of its software so that its computer systems will function properly with
respect to dates in the year 2000 and thereafter.

                         NOTES TO FINANCIAL STATEMENTS

    FOR THE PERIOD FROM JULY 23, 1996 (INCEPTION) THROUGH DECEMBER 31, 1996
                      AND THE YEAR ENDED DECEMBER 31, 1997

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY

    Global Bridges Technologies, Inc. (the "Company"), formerly known as Dream
Fabrications and Design, Inc., was incorporated in California on July 23, 1996.

    The Company designs, develops and markets games, educational, and on-line
titles on behalf of publishers and developers. It also hosts and operates its
subscribers' branded web-based e-mail service using Sitemail, a web-based e-mail
solution which enables the integration of computer software for use in the field
of Internet based e-mail, advertising and commerce, and intranet based content
distribution.

    BASIS OF PRESENTATION

    The Company began operations on July 23, 1996 and has incurred operating
losses through December 31, 1997. On June 11, 1998, the Company sold all of its
stock to Xoom.com, Inc.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported results of operations during the reporting period. Actual results
could differ from those estimates.

    INTERIM FINANCIAL INFORMATION

    The interim financial information as of March 31, 1998 and for the three
months ended March 31, 1997 and 1998 is unaudited but has been prepared on the
same basis as the audited financial statements and includes all adjustments,
consisting only of normal recurring adjustments, that the Company considers
necessary for a fair presentation of its financial position at such date and its
results of operations and cash flows for those periods. Operating results for
the three months ended March 31, 1998 are not necessarily indicative of results
that may be expected for any future periods.

    CASH

    The Company maintains its cash in depository accounts with one financial
institution.

    CONCENTRATIONS OF CREDIT RISK

    The Company conducts business primarily with companies in various industries
throughout the United States. The Company generally does not require collateral.

    INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards Board Statement No. 109, "Accounting for Income
Taxes" ("FAS 109"), which requires the use of the liability method in accounting
for income taxes. Under FAS 109, deferred tax assets and

liabilities are measured using enacted rates and laws that will be in effect
when the differences are expected to reverse.

    REVENUE RECOGNITION

    The Company generally recognizes revenue from consulting services as such
services are performed and when collection is determined to be probable.

    RECENT ACCOUNTING PRONOUNCEMENTS

    As of January 1, 1998 the Company adopted Financial Accounting Standards
Board Statement No. 130, "Reporting Comprehensive Income" ("FAS 130") which
establishes standards for reporting and displaying comprehensive income and its
components in a full set of general-purpose financial statements. The adoption
of this standard had no impact on the Company's financial position,
shareholders' equity (deficit), results of operations or cash flows.

    As of December 31, 1997, the Company has state net operating loss
carryforwards of approximately $1,000 that will expire in 2004. Due to the
change in ownership provisions of the Internal Revenue Code, the availability of
the Company's net operating loss carryforwards will be subject to an annual
limitation due to its acquisition by Xoom.com. This limitation could cause these
losses to expire prior to utilization by the Company.

number of shares of any series of preferred stock without any further vote or

    COMMON STOCK

    The Company is authorized to issue 10,000,000 shares of common stock, no par
value.

    In July 1996, the Company issued 630,000 shares of its common stock in
exchange for cash of $5,000. During September 1997, the Company repurchased
130,000 shares of its common stock from a shareholder in exchange for royalties
to be paid on the future sales of certain products. No payments under this
royalty agreement have been made through December 31, 1997 and March 31, 1998 as
no sales of the products bearing royalties were made in those periods.

5. LEASE COMMITMENTS

    The Company leases its operating facilities under a noncancelable operating
lease agreement that expires in 1998.

    Total rent expense for the period from July 23, 1996 (inception) through
December 31, 1996 and the year ended December 31, 1997 totaled $4,605 and
$4,642, respectively.

6. RELATED PARTY TRANSACTIONS

    During the period from July 23, 1996 (inception) through December 31, 1996
the Company paid certain expenses, totaling $3,918, on behalf of another company
which shares common ownership with the Company. All owed amounts were reimbursed
to the Company as of December 31, 1996.

7. SUBSEQUENT EVENTS

    In April 1998, the Company issued 500,000 shares of its common stock to a
shareholder in exchange for cancellation of a note payable due to him of $3,929
and the assignment of a software license to the Company.

    In May 1998, the operating lease agreement for the lease of the Company's
facilities was assigned by the Company to the stockholder. As a result, all
rental payments are made to the stockholder. The minimum monthly rental payments
did not change from the original lease agreement with the lessor.

    Effective June 11, 1998, the Company entered into a merger agreement with
Xoom.com, Inc. under which the outstanding shares of common stock of the Company
were exchanged for common shares of Xoom.com, Inc. and the right to receive
certain cash distributions from Xoom.com, Inc. The

    FOR THE PERIOD FROM JULY 23, 1996 (INCEPTION) THROUGH DECEMBER 31, 1996
                      AND THE YEAR ENDED DECEMBER 31, 1997

7. SUBSEQUENT EVENTS (CONTINUED)
financial statements do not include any adjustments to the recorded amounts of
assets and liabilities which may result from this transaction.

8. IMPACT OF YEAR 2000 (UNAUDITED)

    The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This situation could result in
a system failure or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

 (INFORMATION FOR THE PERIOD FROM JANUARY 23, 1997 (INCEPTION) THROUGH JUNE 30,
                                      1997
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1998 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY

    Pagecount, Inc. (the "Company") was incorporated in the State of Maryland on
January 23, 1997.

    The Company provides statistical counters which generate the number of times
a user views a customer's web site.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported results of operations during the reporting period. Actual results
could differ from those estimates.

    INTERIM FINANCIAL INFORMATION

    The interim financial information as of June 30, 1998 and for the period
from January 23, 1997 (inception) through June 30, 1997 and the six months ended
June 30, 1998 is unaudited but has been prepared on the same basis as the
audited financial statements and include all adjustments, consisting only of
normal recurring adjustments, that the Company considers necessary for a fair
presentation of its financial position at such date and its results of
operations and cash flows for those periods. Operating results for the six
months ended June 30, 1998 are not necessarily indicative of results that may be
expected for any future periods.

    CASH

    The Company maintains its cash in depository accounts with one financial
institution.

    UNBILLED RECEIVABLES

    Unbilled receivables represent amounts earned as revenue but not yet billed
to customers.

    CONCENTRATIONS OF CREDIT RISK

    The Company conducts business primarily with companies in various industries
throughout the United States. The Company generally does not require collateral.

    For the period from January 23, 1997 (inception) to December 31, 1997, three
customers accounted for 35%, 15%, and 11% of total revenue, and three customers
accounted for 27%, 20%, and 12% of accounts receivable at December 31, 1997.

    For the six months ended June 30, 1998, two customers accounted for 42% and
12% of total revenue, and three customers accounted for 51%, 14%, and 10% of
accounts receivable at June 30, 1998.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

 (INFORMATION FOR THE PERIOD FROM JANUARY 23, 1997 (INCEPTION) THROUGH JUNE 30,
                                      1997
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1998 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    FIXED ASSETS

    Fixed assets are stated at cost, less accumulated depreciation. Depreciation
is computed using the straight-line method over the estimated useful lives of
the assets, which is estimated to be three years.

    INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards Board Statement No. 109, "Accounting for Income
Taxes" ("FAS 109"), which requires the use of the liability method in accounting
for income taxes. Under FAS 109, deferred tax assets and liabilities are
measured based on differences between the financial reporting and tax bases of
assets and liabilities using enacted rates and laws that will be in effect when
the differences are expected to reverse.

    REVENUE RECOGNITION

    Advertising revenue is derived from the sale of banner advertisements under
short-term contracts. To date, the duration of the Company's advertising
commitments has been from one to seven months. Advertising revenue on banner
contracts is recognized ratably in the period in which the advertisement is
displayed, provided that no significant Company obligations remain and
collection of the resulting receivable is probable. Company obligations
typically include the guarantee of a minimum number of "impressions" or times
that an advertisement appears in pages viewed by the users of the Company's
online properties. To the extent minimum guaranteed impressions are not met, the
Company defers recognition of the corresponding revenue until the remaining
guaranteed impression levels are achieved.

    ADVERTISING EXPENSE

    All advertising costs are expensed when incurred. Advertising costs, which
are included in sales and marketing expense, for the period from January 23,
1997 (inception) through December 31, 1997 were $1,124.

    RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1997, the Financial Accounting Standards Board issued Statement No.
130, "Reporting Comprehensive Income" ("FAS 130"), and Statement No. 131,
"Disclosure about Segments of an Enterprise and Related Information" ("FAS
131"). The Company is required to adopt these statements in fiscal year 1998.
FAS 130 establishes new standards for reporting and displaying comprehensive
income and its components. FAS 131 requires disclosure of certain information
regarding operating segments, products and services, geographic areas of
operation and major customers. Adoption of these statements is expected to have
no impact on the Company's consolidated financial position, results of
operations or cash flows.

    The principal source of the Company's deferred tax liabilities is the use of
accelerated depreciation methods for tax purposes.

6. SUBSEQUENT EVENT

    Effective July 24, 1998, the Company entered into an asset sale agreement
under which it sold substantially all of its net assets to Xoom.com, Inc. The
financial statements do not include any adjustments to the recorded amounts of
assets and liabilities which may result from this transaction.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

 (INFORMATION FOR THE PERIOD FROM JANUARY 23, 1997 (INCEPTION) THROUGH JUNE 30,
                                      1997
            AND FOR THE SIX MONTHS ENDED JUNE 30, 1998 IS UNAUDITED)

7. IMPACT OF YEAR 2000 (UNAUDITED)

    The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

    Based on a recent assessment, the Company has determined they will not be
required to modify or replace any portion of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Paralogic Software Corporation

    We have audited the accompanying balance sheet of Paralogic Software
Corporation as of December 31, 1998, and the related statements of operations,
shareholders' equity and cash flows for the period from February 11, 1998
(inception) through December 31, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Paralogic Software
Corporation at December 31, 1998, and the results of its operations and its cash
flows for the period from February 11, 1998 (inception) through December 31,
1998, in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

(INFORMATION FOR THE PERIOD FROM FEBRUARY 11, 1998 (INCEPTION) THROUGH MARCH 31,
                                      1998
            AND THE THREE MONTHS ENDED MARCH 31, 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    THE COMPANY

    Paralogic Software Corporation (the "Company") was incorporated in
California on February 11, 1998.

    The Company provides website chat room hosting, fee-for-service web site
development, and sells internet software. The Company is the result of a spin
out of certain technology rights and assets from a predecessor company,
Paralogic Corporation ("PC"). In exchange for the technology rights and assets,
the Company issued to certain shareholders of PC 4,000,000 shares of Paralogic
Software Corporation common stock.

    BASIS OF PRESENTATION

    The Company has incurred losses since inception and has an accumulated
deficit at December 31, 1998. The accompanying financial statements have been
prepared assuming that the Company will continue as a going concern. The Company
will require additional financing to fund operations in 1999. On June 10, 1999,
the Company entered into an agreement under which it will be acquired by
Xoom.com, Inc. The majority of the shareholders of the Company are also
shareholders and officers of Xoom.com, Inc. Effective June 16, 1999, the Company
was acquired by Xoom.com, Inc. The financial statements do not include any
adjustments to the recorded amounts of assets and liabilities which may result
from this transaction.

    USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported results of operations during the reporting period. Actual results
could differ from those estimates.

    INTERIM FINANCIAL INFORMATION

    The interim financial information as of March 31, 1999 and for the three
months ended March 31, 1998 and 1999 is unaudited but has been prepared on the
same basis as the audited financial statements and includes all adjustments,
consisting only of normal recurring adjustments, that the Company considers
necessary for a fair presentation of its financial position at such date and its
results of operations and cash flows for those periods. Operating results for
the three months ended March 31, 1999, are not necessarily indicative of results
that may be expected for any future periods.

    CASH

    The Company maintains its cash in depository accounts with one financial
institution.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(INFORMATION FOR THE PERIOD FROM FEBRUARY 11, 1998 (INCEPTION) THROUGH MARCH 31,
                                      1998
            AND THE THREE MONTHS ENDED MARCH 31, 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    CONCENTRATIONS OF CREDIT RISK

    The Company conducts business primarily with individuals and companies
throughout the United States. The Company generally does not require collateral.

    FIXED ASSETS

    Fixed assets are recorded at cost, less accumulated depreciation.
Depreciation is computed using the straight-line method over the estimated
useful lives of three, five, and seven years for computer software, computer
hardware and furniture and fixtures, respectively.

    REVENUE RECOGNITION

    SERVICES

    The majority of the Company's service revenue is from fees charged for chat
network hosting and web site development which are recognized when the services
are performed.

    LICENSE FEES

    The Company licenses software under non-cancelable license agreements to
end-users. License fee revenue is recognized when a non-cancelable license
agreement has been signed, the product has been delivered, there are no
uncertainties surrounding product acceptance, the fees are fixed and
determinable and collection is considered probable. Customer support revenues
are deferred and recognized on a straight-line basis over the period covered by
such agreements.

    INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards Board Statement No. 109, "Accounting for Income
Taxes" ("FAS 109"), which requires the use of the liability method in accounting
for income taxes. Under FAS 109, deferred tax assets and liabilities are
measured based on differences between the financial reporting and tax bases of
assets and liabilities using enacted rates and laws that are expected to be in
effect when the differences are expected to reverse. No provision for income
taxes was recorded on the income for the period from February 11, 1998
(inception) through March 31, 1998, as the Company incurred a loss for the
entire period from February 11, 1998 through December 31, 1998.

    STOCK BASED COMPENSATION

    The Company accounts for stock-based awards to employees under the intrinsic
value method in accordance with Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and has adopted the
disclosure-only alternative of Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" ("FAS 123").

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(INFORMATION FOR THE PERIOD FROM FEBRUARY 11, 1998 (INCEPTION) THROUGH MARCH 31,
                                      1998
            AND THE THREE MONTHS ENDED MARCH 31, 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    RECENT ACCOUNTING PRONOUNCEMENTS

    As of January 1, 1998, the Company adopted Financial Accounting Standards
Board Statement No. 130, "Reporting Comprehensive Income" ("FAS 130") which
establishes standards for reporting and displaying comprehensive income and its
components in a full set of general-purpose financial statements. The adoption
of this standard had no impact on the Company's financial position,
shareholders' equity, results of operations or cash flows.

    AICPA Accounting Standards Executive Committee Statement of Position 97-2,
"Software Revenue Recognition," ("SOP 97-2") and Statement of Position 98-4
("SOP 98-4"), "Deferral of the Effective Date of a Provision" of SOP 97-2,
Software Revenue Recognition or SOP 98-4, which contain new rules for timing of
recognition of software company revenues, particularly as to license fee
revenues where there are multiple elements to be delivered under a contract or
arrangement with a customer, became effective for transactions beginning in
1998. Management believes the Company's current policy and its practices conform
to the rules in these new accounting pronouncements. Under the Company's current
policy, license fees on standard software products not requiring substantial
modification and customization are recognized as revenue upon shipment to
customers.

    In December 1998, the American Institute of Certified Public Accountants or
AICPA issued Statement of Position 98-9, Modification of SOP 97-2, Software
Revenue Recognition, With Respect Certain Transactions, or SOP 98-9. SOP 98-9
amends SOP 98-4 to extend the deferral of the application of certain passages of
SOP 97-2 provided by SOP 98-4 through fiscal years beginning on or before March
15, 1999. All other provisions of SOP 98-9 are effective for transactions
entered into in fiscal years beginning after March 15, 1999. The Company has not
yet determined the effect of the final adoption of SOP 98-9 on its future
revenues and results of operations.

2. FIXED ASSETS

    Fixed assets consist of the following:

4. INCOME TAXES

    There has been no provisions for federal or state income taxes for any
period as the Company has incurred operating losses in all periods.

    Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets as of December 31, 1998 are as follows:

<TABLE>
<S>                                                                                  <C>

Total..............................................................................  $      --
                                                                                     ---------
                                                                                     ---------
</TABLE>

    Realization of deferred tax assets is dependent upon future earnings, if
any, the timing and amount of which are uncertain. Accordingly, the net deferred
tax assets have been fully offset by a valuation allowance as it is more likely
than not that the deferred tax assets will not be realized. The net valuation
allowance increased by $11,965 during the period from February 11, 1998
(inception) through December 31, 1998.

    As of December 31, 1998, the Company had net operating loss carryforwards
for federal income tax purposes of approximately $22,000 which expire in the
year 2018.

    Due to the "change in ownership" provisions of the Internal Revenue Code,
the availability of the Company's net operating loss credit carryforwards will
be subject to an annual limitation against taxable income in future periods if a
change in ownership of more than 50% of the value of the Company's stock should
occur over a three-year period which could substantially limit the eventual
utilization of these carryforwards.

5. SHAREHOLDERS' EQUITY

    CONVERTIBLE PREFERRED STOCK

    The Company is authorized to issue 400,000 shares of preferred stock all of
which is designated "Series A Preferred." The Company will from time to time in
accordance with the laws of the State of California increase the authorized
amount of its Common Stock if at any time the number of shares of Common Stock
remaining unissued and available for issuance is not sufficient to permit
conversion of the Preferred Stock.

    In November 1998, the Company issued 252,121 shares of Series A Preferred
Stock, which was outstanding as of December 31, 1998 and March 31, 1999. The
holders of the outstanding Preferred Stock are entitled to receive, when and as
declared by the Board of Directors, dividends at the rate of $0.05 per share per
annum, payable in preference and priority to any payment of any dividend on
Common Stock of the Company.

            AND THE THREE MONTHS ENDED MARCH 31, 1999 IS UNAUDITED)

5. SHAREHOLDERS' EQUITY (CONTINUED)
    In the event of any liquidation, dissolution, or winding up of the Company,
either voluntary or involuntary, the holders of the Preferred Stock will be
entitled to receive, prior and in preference to any distribution of any of the
assets or surplus funds of the Company to the holders of the Common Stock by
reason of their ownership of such stock, the amount of $0.66 per share for each
share of Preferred Stock then held by them.

    Each share of the Preferred Stock is convertible, at the option of the
holder into such number of fully paid and non assessable shares of Common Stock
as is determined by dividing $0.66 by the Conversion Price in effect at the time
of conversion.

    COMMON STOCK

    The Company is authorized to issue 7,000,000 shares of common stock at par
value. As of December 31, 1998 and March 31, 1999, the Company has 4,972,726
shares of common stock issued and outstanding.

    STOCK OPTIONS

    In November 1998, the Board of Directors of the Company approved the
Company's 1998 stock incentive plan (the "1998 Plan") and initially reserved
1,500,000 shares for issuance thereunder. Stock options generally vest over
different periods from immediately to 25% at the end of the first year and
monthly thereafter up to a maximum of four years.

    A summary of activity under the 1998 Plan is as follows:

5. SHAREHOLDERS' EQUITY (CONTINUED)
    DEFERRED COMPENSATION

    The Company has recorded deferred compensation charges of $433,723 and
$3,425,042 during the period from February 11, 1998 (inception) through December
31, 1998 and for the three months ended March 31, 1999, respectively, for the
difference between the exercise price and the deemed fair value of certain stock
options granted by the Company. These amounts are being amortized by charges to
operations, using the graded method, over the vesting periods of the individual
stock options, which are generally four years.

    PRO FORMA DISCLOSURE OF THE EFFECT OF STOCK-BASED COMPENSATION

    The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FAS 123 requires the use of
option valuation models that were not developed for use in valuing employee
stock options.

    Pro forma information regarding net income (loss) and net income (loss) per
share is required by FAS 123. This information is required to be determined as
if the Company has accounted for its employee stock options under the fair value
method of FAS 123. Under this method, the estimated fair value of the options is
amortized to expense over the options' vesting period. The fair value for these
options was estimated at the date of grant using a Black-Scholes option pricing
model with the following weighted-average assumptions:

                                                                                    1998

<S>                                                                            <C>

Expected dividend yield......................................................            0%
</TABLE>

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions, including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimates, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

    The effect of applying the Black-Scholes option valuation model did not
result in pro forma net loss amounts that are materially different from
historical amounts reported. Therefore, such pro forma amounts are not reported
herein. Future pro forma amounts may be materially different from actual amounts
reported.

    The weighted average fair value of options granted to employees during the

per share.

6. LEASE COMMITMENTS

    The Company leases its operating facilities under a noncancelable operating
lease agreement that expires in October 1999. The lease commitment for 1999 is
$19,350.

    Total rent expense for the period from February 11, 1998 (inception) through
December 31, 1998 was $12,250.

7. IMPACT OF YEAR 2000 (UNAUDITED)

    The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This situation could result in
a system failure or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

    The Company believes that it will not be required to modify or replace any
portion of its software so that its computer system will function properly with
respect to dates in the year 2000 and thereafter.

                         NOTES TO FINANCIAL STATEMENTS

 (INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1998 AND 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

    On October 16, 1998, MightyMail Networks LLC and Oompala, Inc. merged to
form MightyMail Networks, Inc. (the "Company"). MightyMail Networks LLC was
formed on June 15, 1998, in Delaware. Oompala, Inc. was incorporated on January
10, 1995, in California.

    Oompala, Inc. was previously a fee-for-service company whereby products were
developed on a contractual basis. After the merger, the Company began focusing
on an enhanced e-mail product which enables customization of e-mail according to
user preferences.

BASIS OF PRESENTATION

    The Company experienced recurring losses and has an accumulated deficit at
December 31, 1998. The accompanying financial statements have been prepared
assuming that the Company will continue as a going concern. The Company will
require additional financing to fund operations in 1999. Effective May 3, 1999,
the Company agreed to be acquired by Xoom.com, Inc. The financial statements do
not include any adjustments to the recorded amounts of assets and liabilities
which may result from this transaction.

INTERIM FINANCIAL INFORMATION

    The interim financial information for the three months ended March 31, 1998
and 1999, is unaudited but has been prepared on the same basis as the audited
financial statements and includes all adjustments, consisting only of normal
recurring adjustments, that the Company considers necessary for a fair
presentation of its financial position at such date and its results of
operations and cash flows for those periods. Operating results for the three
months ended March 31, 1999, are not necessarily indicative of results that may
be expected for any future periods.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements and
the reported results of operations during the reporting period. Actual results
could differ from those estimates.

CASH

    The Company maintains its cash in depository accounts with one financial
institution.

CONCENTRATIONS OF CREDIT RISK AND CREDIT EVALUATIONS

    Financial instruments which subject the Company to concentrations of credit
risk consist primarily of trade accounts receivable. The Company conducts
business with companies in various industries throughout the world and with
individuals over the Internet. The Company performs ongoing credit evaluations
of its corporate customers and generally does not require collateral. Sales to
individuals are principally paid for in cash. To date, the Company has not
experienced any credit losses.

 (INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1998 AND 1999 IS UNAUDITED)

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FIXED ASSETS

    Fixed assets are stated at cost less accumulated depreciation. Depreciation
is computed using the straight-line method over the estimated useful lives of
three years. Useful lives are evaluated regularly by management in order to
determine recoverability in light of current technological conditions. The
Company identifies and records impairment losses on fixed assets when events and
or circumstances indicate that such assets might be impaired. To date, no such
impairment has been recorded.

INCOME TAXES

    The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"), which requires the use of the liability method in accounting for income
taxes. Under FAS 109, deferred tax assets and liabilities are measured based on
differences between the financial reporting and tax bases of assets and
liabilities using enacted tax rates and laws that are expected to be in effect
when the differences are expected to reverse.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based awards to employees in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25") and has adopted the disclosure-only alternative of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123").

REVENUE RECOGNITION

    The Company's primary source of revenue during 1997 and 1998 was
fee-for-service on a contractual basis. These revenues were recognized as the
Company provided the services. There has been no revenue since July 1998 when
the Company changed its focus to develop its enhanced e-mail product.

LICENSE FEES

    During 1997, the Company licensed software under non-cancelable license
agreements to end-users and non-cancelable sub-license agreements to resellers.
License fee revenues were recognized when a non-cancelable license agreement was
signed, the product was delivered, there were no uncertainties surrounding
product acceptance, the fees were fixed and determinable and collection was
probable.

EXPORT SALES

    Export sales were to customers in Japan and totaled $303,900 and $4,408
which represent 26% and 1% of net revenue for the years ended December 31, 1997
and 1998.

RECENT ACCOUNTING PRONOUNCEMENTS

    As of January 1, 1998, the Company adopted Financial Accounting Standards
Board Statement No. 130 ("SFAS 130"), "Reporting Comprehensive Income, which
establishes standards for reporting and displaying comprehensive income and its
components in a full set of general-purpose financial statements. The Company
had no material components of comprehensive income. The adoption of this
standard has

had no impact on the Company's financial position, stockholders' equity, results
of operations or cash flows. Accordingly, the Company's comprehensive loss for
the years ended December 31, 1997 and 1998 and the three months ended March 31,
1998 and 1999, is equal to its reported loss.

2. FIXED ASSETS

3. INCOME TAXES

    The Company's shareholders have previously elected to be treated as an S
Corporation for federal and state income tax purposes. As an S Corporation, the
current federal and state taxable income is allocated to the stockholders who
are responsible for the payment of taxes thereon. Accordingly, the accompanying
financial statements do not include a provision for federal or state income
taxes.

4. STOCKHOLDERS' EQUITY

    The Company's Board of Directors authorized 10,000,000 shares of preferred
stock and 20,000,000 shares of common stock both with a par value of $0.001 per
share.

STOCK SPLIT

    In October 1998, the Company completed a 2.48-to-1 stock split of the
outstanding shares of common stock. All share information and per share amounts
in the accompanying financial statements have been retroactively adjusted to
reflect the effect of this stock split.

CONVERTIBLE PREFERRED STOCK

    The Company is authorized to issue 1,620,000 shares of Series A preferred
stock, of which 1,020,000 shares were issued and outstanding at March 31, 1999
at prices ranging from $0.36 to $0.50 per share. The holders of the outstanding
Preferred Stock are entitled to receive, when and as declared by the Board of
Directors, dividends at the rate of $0.04 per share per annum, payable in
preference and priority to any payment of any dividend on Common Stock of the
Company.

    In the event of any liquidation, dissolution, or winding up of the Company,
either voluntary or involuntary, the holders of the Preferred Stock will be
entitled to receive, prior and in preference to any distribution of any of the
assets or surplus funds of the Company to the holders of the Common Stock by

reason of their ownership of such stock, the amount of $0.50 per share for each
share of Preferred Stock then held by them.

    Each share of Preferred Stock is convertible, at the option of the holder
into such number of fully paid and non assessable shares of Common Stock as is
determined by dividing $0.50 by the conversion price in effect at the time of
conversion.

    An additional 200,000 shares of Series A preferred shares were issued for
cash on April 5, 1999.

WARRANTS

    In connection with the issuance of Series A preferred stock in the year
ended December 31, 1998 and the three months ended March 31, 1999, the Company
issued warrants to purchase a total of 350,000 shares of Series A preferred
stock at a price of $0.50 per share. These warrants are immediately exercisable
and expire on December 31, 1999.

COMMON SHARES

    The Company issued 150,000 shares of common stock in conjunction with
subscriptions of Series A preferred stock in the period December 1998 through
January 1999 at prices ranging from $0.36 to $0.42 per share.

STOCK OPTION PLAN

    The Company has reserved 1,017,125 shares of common stock under the
Company's 1999 Stock Option Plan (the "Plan"). The Plan provides for incentive
stock options, as defined by the Internal Revenue Code, to be granted to
employees and certain non-employee consultants, at an exercise price not less
than 100% of the fair value at the grant date as determined by the Board of
Directors. The Plan also provides for nonqualified stock options to be issued to
non-employee officers, directors and consultants at an exercise price of not
less than 85% of the fair value at the grant date unless optionee is a 10%
shareholder in which case option price will not be less than 110% of such fair
value. Option vesting schedules are determined by the Board of Directors at the
time of issuance. Stock options generally vest over different periods ranging
from immediately to 50% at the end of the first year and monthly thereafter up
to a maximum of three years. Upon a change of control, as defined in the Plan,
50% of unvested options become immediately vested.

    A summary of the option activity is as follows:

    The Company granted options for 674,926 shares of common stock under the
1999 Stock Option Plan to employees and certain non-employee consultants on
April 30, 1999. These options vest over a period of 3 years and are immediately
exercisable at $2.00 per share.

DEFERRED COMPENSATION

    The Company has recorded deferred compensation charges of $0 and $1,468,067
for the year ended December 31, 1998 and for the three months ended March 31,
1999, respectively, for the difference between the exercise price and the deemed
fair value of certain stock options granted by the Company. These amounts are
being amortized by charges to operations, using the graded method, over the
vesting periods of the individual stock options, which range from immediately to
three years.

OPTIONS ISSUED TO CONSULTANTS

    The Company granted options to purchase 55,000 shares of common stock to
consultants at exercise price of $0.05 per share on March 1, 1999. These options
were granted in exchange for consulting services performed. The Company valued
these options (using the Black-Scholes valuation method) at $325,450, for the
three months ended March 31, 1999. This amount was charged to operations in the
three months ended March 31, 1999.

PRO FORMA DISCLOSURE OF THE EFFECT OF STOCK-BASED COMPENSATION

    The Company has elected to follow APB 25 and related interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FAS 123 requires the use of
option valuation models that were not developed for use in valuing employee
stock options. Pro forma information regarding net income (loss) and net income
(loss) per share is required by FAS 123. This information is required to be
determined as if the Company has accounted for its employee stock options under
the fair value method of FAS 123. Under this method, the estimated fair value of
the options is amortized to expense over the options' vesting period. The fair
value for these options was

</TABLE>

    Because FAS 123 is applicable only to options granted since inception, its
adjusted effect will not be fully reflected until 2000.

    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions, including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimates, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

    The weighted-average fair value of options granted to employees during the
three months ended March 31, 1999 was $0.04.

5. COMMITMENTS

    The Company leases its facilities under noncancelable leases for varying

6. RELATED PARTY TRANSACTIONS

    During the period from December 23, 1998 through March 31, 1999, the Company
issued stock subscriptions receivable to investors in exchange for shares of
preferred and common stock. These subscriptions receivable are due upon demand
and bear no interest. As of March 31, 1999, there were no outstanding amounts
due under subscriptions receivable.

7. YEAR 2000 (UNAUDITED)

    The Year 2000 Issue is the result of computer programs being written using
two-digits rather than four to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This situation could result in
a system failure or miscalculations causing disruptions of operations,
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

    The Company believes that it will not be required to modify or replace any
portion of its software so that its computer system will function properly with
respect to dates in the year 2000 and thereafter.

         REPORT OF PRICEWATERHOUSECOOPERS LLP, INDEPENDENT ACCOUNTANTS

To the Shareholders of
LiquidMarket, Inc.

    In our opinion, the accompanying balance sheet of LiquidMarket, Inc. (A
Company In The Developmental Stage) (the "Company") and the related statements
of operations, shareholders' equity and cash flows present fairly, in all
material respects, the financial position of the Company as of December 31,
1998, and the results of its operations and its cash flows for the period June
12, 1998 (Date of Inception) through December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

    The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company's negative cash flows from operations and
limited capital resources raise substantial doubt about its ability to continue
as a going concern. Management's plans in regard to these matters are also
addressed in Note 1. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

                     (A COMPANY IN THE DEVELOPMENTAL STAGE)

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND SIGNIFICANT BUSINESS RISKS:

NATURE OF BUSINESS

    LiquidMarket (the "Company") was incorporated in June 1998 in the State of
Delaware and is engaged in software development. As of December 31, 1998, the
Company is a development stage enterprise, as defined in Financial Accounting
Standards Board Statement No. 7. Since inception, the Company has devoted
substantially all of its efforts toward the development of its product and
establishing new business. The Company's business is extremely competitive and
is characterized by rapid technological change, new product development and a
competitive environment for the attraction and retention of knowledge workers.
The Company is an early stage enterprise and is subject to all the risks
associated with development stage companies.

SIGNIFICANT BUSINESS RISKS

    Since its inception, the Company has incurred significant operating losses.
The ability of the Company to successfully carry out its business plan is
primarily dependent upon its ability to (1) obtain sufficient additional
capital, (2) overcome product development issues, and (3) generate significant
revenues and cash flows through the future sales of its primary product.

BASIS OF PRESENTATION

    The Company's financial statements for the period June 12, 1998 (Date of
Inception) through December 31, 1998 have been prepared on a going-concern basis
which contemplates the realization of assets and the settlement of liabilities
and commitments in the normal course of business. The Company had negative cash
flows from operations of ($445,472), and a net loss and an accumulated deficit
of ($675,588), as of December 31, 1998 and for the period June 12, 1998 (Date of
Inception) through December 31, 1998. The Company expects to incur additional
expenditures to complete and enhance its product. The Company's revenues from
product sales, and its working capital, may not be sufficient to fund its
working capital needs and meet its expansion objectives over the next twelve
months. Management recognizes that the Company may need to obtain additional
financing or consider reductions in its operating costs to enable it to continue
operations with available resources. Management's plans include raising funds
through the sale of additional equity securities, and expect that these efforts
will result in the additional capital needed to fund the Company's operations
and planned expansion. There can be no assurance that these funds will be
sufficient to adequately fund the operations and that the Company will achieve
profitability or positive cash flows.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

    In the normal course of preparing financial statements in conformity with
generally accepted accounting principles, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash and cash
equivalents are carried at cost, which approximates fair value.

CONCENTRATION OF CREDIT RISK

    Financial instruments, which potentially subject the Company to
concentration of credit risk, consist principally of cash and short-term
investments. The Company invests its excess cash in money market funds with
major financial institution. At times the Company's cash balances may be in
excess of the FDIC Insurance limits.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation is computed using the straight-line method based upon
the estimated useful lives of the assets. Leasehold improvements are amortized
over the shorter of the estimated useful life or the life of the lease. Useful
lives are evaluated regularly by management in order to determine recoverability
in light of current technological conditions. Maintenance and repairs are
charged to expense as incurred while renewals and improvements are capitalized.
Upon the sale or retirement of property and equipment, the accounts are relieved
of the cost and the related accumulated depreciation or amortization, with any
resulting gain or loss included in the Statement of Operations.

SOFTWARE DEVELOPMENT COSTS

    Under the provisions of Statement of Financial Accounting Standards ("SFAS")
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," the Company is required to capitalize software development
costs when "technological feasibility" of the product has been established and
anticipated future revenues ensure recovery of the capitalized amounts. As of
December 31, 1998, "technological feasibility" had not been reached and,
accordingly, no amount of software development costs have been capitalized.

    Costs incurred in the research and development of products are expensed as
incurred.

INCOME TAXES

    The Company utilizes the liability method of accounting for income taxes.
Under this method, deferred tax liabilities and assets are determined based on
the difference between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the period in which the
differences are expected to reverse. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount expected to be realized.

STOCK-BASED EMPLOYEE COMPENSATION

    SFAS No. 123, "Accounting for the Awards of Stock-Based Compensation to
Employees," encourages, but does not require, companies to record compensation
costs for stock-based compensation plans at fair value. The Company has adopted
the disclosure requirements of SFAS No. 123, which involves pro forma

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
disclosure of net income under SFAS No. 123, detailed descriptions of plan terms
and assumptions used in valuing stock option grants. The Company has elected to
account for stock-based employee compensation awards in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB No. 25").

COMPREHENSIVE INCOME

    Effective June 12, 1998 (Date of Inception the Company adopted the
provisions of SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130
establishes standards for reporting comprehensive income and its components in
financial statements. Comprehensive income, as defined, includes all changes in
equity (net assets) during a period from non-owner sources. To date, the Company
has not had any transactions that are required to be reported in comprehensive
income.

INTERIM FINANCIAL STATEMENTS

    The accompanying unaudited financial amounts as of June 30, 1999 and the six
months then ended, include all adjustments (consisting of normal recurring
entries) which management believes are necessary for a fair presentation of the
financial position and results of operations for the interim period presented.
Certain information and footnotes disclosures normally included in financial
statements prepared in accordance with generally accounting principles have been
condensed or omitted in accordance with quarterly reporting guidelines.

3. PROPERTY AND EQUIPMENT, NET:

    Property and equipment at December 31, 1998 and June 30, 1999 consist of the

4. INCOME TAXES:

    The provision for income taxes represents the minimum state franchise taxes.
As of December 31, 1998, the Company has deferred income tax assets of
approximately $256,000, which has been offset by a 100% valuation allowance. The
deferred tax asset is primarily due to the Company's federal and state net
operating loss (NOL's) carryforwards available to offset future taxable income,
if any, of approximately $640,000 which begin to expire in 2013 and 2006 for
federal and state income tax purposes, respectively. However, the ultimate
realization of these NOL's is dependent on future taxable income of the Company,
subject to certain limitations, as defined under Section 382 of the Internal
Revenue Code.

4. INCOME TAXES: (CONTINUED)
    As a result of the Company being in the development stage and the net loss
incurred during the period from June 12, 1998 (Date of Inception) through
December 31, 1998, management believes a valuation allowance for the entire
deferred tax asset, after considering deferred tax liabilities, is required.

SOFTWARE LICENSE

    The Company licenses certain technology for use in its product. Pursuant to
the terms of the agreement, the Company is obligated to pay $55,000 during the
first two years of the term of the agreement. In addition, the Company may
exercise an option to purchase the software for $110,000. Payments previously

6. CAPITALIZATION:

CAPITAL

    The authorized capital stock of the Company consists of 15,000,000 shares of
common stock, $.001 par value and 5,450,000 shares of preferred stock, $.001 par
value, of which 3,200,000 shares have been designated as Series A Stock, and
2,250,000 shares have been designated as Series B Stock.

CONVERTIBLE PREFERRED STOCK

    Preferred stockholders may at any time elect to convert shares of preferred
stock into common stock. In addition, all outstanding shares of preferred stock
shall automatically be converted into shares of common stock if either (i) the
Company consummates an underwritten initial public offering with gross proceeds
of at least $15,000,000 or (ii) more than 80% of the outstanding shares of
preferred stock have been converted into common stock. Preferred stock shall
initially convert into common stock on a one-for-one basis. The conversion price
of the Series A and B preferred stock shall initially equal $0.25 and $0.75 per
share, respectively, subject to adjustment for stock splits.

    The Series A and B preferred stock shall have a liquidation value (the
"Liquidation Value") equal to the per share original cost of $0.25 and $0.75,
respectively. Liquidation value will increase by the amount of

6. CAPITALIZATION: (CONTINUED)
any declared but unpaid dividends on the preferred stock. Upon a liquidation,
dissolution or winding-up of the business of the Company, the holders of the
preferred stock shall be entitled to a preference in an amount equal to the
greater of the (i) Liquidation Value (subject to appropriate adjustment in the
event of any stock dividend, stock split, or the like), or (ii) such amount per
share as would have been payable had each share of preferred stock been
converted into common stock prior to such liquidation. A merger or consolidation
of the Company in which the Company is not the surviving entity, or the sale of
all or substantially all of the assets of the Company, shall be considered to be
a liquidation, unless otherwise elected by the holders of a majority of the
outstanding shares of preferred stock.

    Each share of Series A and B preferred stock will be entitled to dividends
as declared by the Board of Directors but, in any event, at the same rate as the
common stock with declared dividends paid first to the holders of the Series B
preferred and Series A preferred, then to the holders of the common stock.

    The Series A preferred stock will vote with the Series B preferred stock and
the common stock as a single class on all matters (on an as-converted basis).

7. STOCK OPTIONS (ALL INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1999 IS
UNAUDITED):

    In October 1998, the Company adopted the 1998 stock incentive plan (the
"Plan") which provides for grants to employees and non-employees of incentive
stock options to purchase up to an aggregate of 2,200,000 shares of common
stock. The options vest 25% at the first-year anniversary from the date of grant
and 2.0833% on a monthly basis thereafter up to a period of 4 years. All options
generally expire after ten years.

    For the period June 12, 1998 (Date of Inception) through December 31, 1998,
the Company granted options to purchase 530,000 shares of common stock at an
exercise price of $0.05 per share. The estimated fair value of common stock on
the dates of grant was $0.25 per share. No options were exercisable at December
31, 1998 and options to purchase 1,670,000 shares of common stock remain
available for future grants.

    From January 1, 1999 through April 15, 1999, the Company granted options to
employees to purchase 165,000 shares of common stock at an exercise price of
$0.08 per share. The estimated fair value of the common stock on the dates of
grant was $0.75 per share. In addition, in May 1999, the Company entered into a
consulting agreement with a Board member to provide strategic consulting
services in exchange for granting options to purchase 325,000 shares of the
Company's common stock at an exercise price of $0.08 per share vesting in
quarterly installments over a one year period. In the event there is an
Acquisition Event (as defined in the Plan) these options become immediately
exercisable in full prior to the Acquisition Event. The estimated fair value of
services to be provided approximates the estimated fair value of the common
stock on the date of grant of approximately $1.83 per share. No options were
exercisable at June 30, 1999 and options to purchase 1,180,000 shares of common
stock remain available for future grants.

    The fair value of the options granted was estimated on the date of grant
using the minimum value method with the following assumptions: risk-free
rate--4.26%; expected option life--5 years; expected forfeitures rate--none;
expected dividend yield--none.

7. STOCK OPTIONS (ALL INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1999 IS
UNAUDITED): (CONTINUED)
    The Company uses the intrinsic value method of accounting for stock-based
compensation for employees prescribed by APB No. 25, and, accordingly, adopted
the disclosure-only provisions of SFAS No. 123. Had the Company applied the
provisions set forth in SFAS No. 123, the Company's net loss would not be
materially different from the amount presented for the period June 12, 1998
(Date of Inception) through December 31, 1998.

    In connection with the stock option grants noted above, the Company
recognized unearned compensation of $185,294 which is being amortized over the
vesting period of the related options generally one to four years. The Company
recorded amortization of deferred compensation expense of $593,356 during the
six months ended June 30, 1999 relating to the stock options granted, of which
approximately $568,750 related to the options granted to the Board member noted
above (see Note 8).

8. SUBSEQUENT EVENT (UNAUDITED)

    In July 1999, the Company entered into an agreement and plan of merger to
sell all the Company's outstanding preferred and common shares.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL INFORMATION

    The excess of the purchase cost of the Paralogic Corporation, Global Bridges
Technologies, Inc., Pagecount, Inc., Paralogic Software Corporation, Might Mail
Networks, Inc. and LiquidMarket, Inc. mergers over the fair value of the net
assets acquired has been allocated to goodwill. The total estimated purchase
cost of the LiquidMarket, Inc. merger has been allocated on a preliminary basis
to assets and liabilities based on management's estimate of their fair values.
The final purchase cost allocation for the LiquidMarket, Inc. merger occurred on
August 3, 1999 and was not materially different from the preliminary basis
presented herein. The adjustments to the unaudited pro forma condensed combined
balance sheet as of June 30, 1999 exclude the effect of Paralogic Corporation,
Global Bridges Technologies, Inc., Pagecount, Inc., Paralogic Software
Corporation and Mighty Mail Networks, Inc. mergers, as these were consummated in
prior to June 30, 1999.

    The adjustments to the unaudited pro forma condensed combined balance sheet
as of June 30, 1999, have been calculated as if the LiquidMarket, Inc. merger
occurred on June 30, 1999 and are as follows:

(1) To reflect the acquisition of LiquidMarket, Inc. for total estimated
    purchase price of approximately $38,747,000. The purchase consideration
    consists of the following:

    - Issuance of 824,325 shares of Xoom.com's common stock to the shareholders
      of LiquidMarket, Inc., with a fair value of $33,547,000. An additional
      106,101 shares may be included in the purchase price if specific
      performance objectives are met. The fair value per share of Xoom.com's
      common stock issued in the LiquidMarket, Inc. acquisition is based on the
      average closing price of Xoom.com's common stock on August 3, 1999 (the
      day the merger was announced) and the three days prior and subsequent to
      such date.

    - Assumption of options related to the LiquidMarket, Inc. acquisition to
      purchase 130,750 shares, of Xoom.com's common stock with a fair value of
      $4,900,000. 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 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 5.75%

       - Expected dividend rate of 0%

    - Other related transaction and merger costs estimated to be $300,000 for
      the aquisition of LiquidMarket, Inc.

    intangible assets as follows:

(3) To reflect the elimination of the historical stockholders' equity accounts
    of LiquidMarket, Inc.

The adjustments to the unaudited pro forma condensed combined statement of
operations for the year ended December 31, 1998 and the six months ended June
30, 1999, have been calculated assuming that the mergers occurred as of January
1, 1998 and January 1, 1999, respectively and are as follows:

(A) The purchased in-process research and development charges of $1,082,000 and
    $1,542,000 related to MightyMail Networks, Inc. and Paralogic Software
    Corporation, respectively, have been excluded from the net loss for the year
    ended December 31, 1998 and the six months ended June 30, 1999, as they
    represent non-recurring charges. Additionally, purchased in-process research
    and development charges of $330,000 and $130,000 related to the Paralogic
    Corporation and Pagecount, Inc. acquisitions, respectively, have been
    excluded from the net loss for the year ended December 31, 1998. No
    purchased in-process research and development charges are anticipated for
    the LiquidMarket, Inc. merger.

(B) To reflect the amortization of goodwill and other intangible assets
    resulting from the MightyMail Networks, Inc., Paralogic Software
    Corporation, and LiquidMarket, Inc. acquisitions. During the year ended
    December 31, 1998, this amount also reflects the amortization of goodwill
    and other intangible assets resulting from the Paralogic Corporation, Global
    Bridges Technologies, Inc. and Pagecount, Inc. acquisitions. The goodwill
    and other intangible assets are being amortized over periods of twenty-four
    to forty-eight months.

(C) Basic and diluted net loss per share reflects the issuance of 682,410,
    200,731, 335,947, 748,816 and 930,426 shares of Xoom.com's common stock
    related to the Paralogic Corporation, Global Bridges Technologies, Inc.,
    MightyMail Networks, Inc., Paralogic Software Corporation and LiquidMarket,
    Inc. acquisitions, respectively, 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. The shares
    issued to the shareholders of MightyMail Networks, Inc., and LiquidMarket,
    Inc. include 33,593 and 106,101 shares, respectively, held in escrow which
    will be released upon the achievement of specific performance obligations.

holders thereof, at the Effective Time, all shares of Xoom Stock shall be
canceled and shall cease to exist, and each holder of a certificate which
immediately prior to the Effective Time represented any such shares of Xoom
Stock (a "CERTIFICATE") shall thereafter cease to have any rights with respect
to such shares of Xoom Stock, except as provided herein or by law.

    (c) Each share of Xoom Stock issued and owned or held by Xoom at the
Effective Time shall, by virtue of the Merger, cease to be outstanding and shall
be canceled and no stock of Xenon 2 or other consideration shall be delivered in
exchange therefor.

    (d) Each share of common stock, par value $0.0001 per share, of Xenon 3
issued and outstanding immediately prior to the Effective Time, shall be
converted into one validly issued, fully paid and

                                     A-1-7
<PAGE>
nonassessable share of common stock, par value $0.0001 per share, of the
Surviving Corporation as of the Effective Time.

    2.9  EXCHANGE FUND.  Prior to the Effective Time, Xenon 2 shall appoint a
commercial bank or trust company (or a subsidiary thereof) reasonably acceptable
to Xenon 2 and Xoom to act as exchange agent hereunder for the purpose of
exchanging Certificates for the Merger Consideration (the "EXCHANGE AGENT"). At
or prior to the Effective Time, Xenon 2 shall deposit with the Exchange Agent,
in trust for the benefit of holders of shares of Xoom Stock, certificates
representing the Class A Common Stock issuable pursuant to SECTION 2.8 in
exchange for outstanding shares of Xoom Stock.

    2.10  EXCHANGE PROCEDURES.  As soon as reasonably practicable after the
Effective Time, Xenon 2 shall cause the Exchange Agent to mail to each holder of
a Certificate (i) a letter of transmittal which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon delivery of the Certificates to the Exchange Agent, and which letter
shall be in customary form and have such other provisions as Xenon 2 may
reasonably specify and (ii) instructions for effecting the surrender of such
Certificates in exchange for the applicable Merger Consideration. Upon surrender
of a Certificate to the Exchange Agent together with such letter of transmittal,
duly executed and completed in accordance with the instructions thereto, and
such other documents as may reasonably be required by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange therefor one
or more shares of Class A Common Stock (which shall be in uncertificated
book-entry form unless a physical certificate is requested) representing, in the
aggregate, the number of shares that such holder has the right to receive
pursuant to SECTION 2.8. In the event of a transfer of ownership of Xoom Stock
which is not registered in the transfer records of Xoom the proper number of
shares of Class A Common Stock may be issued with respect to such Xoom Stock to
such a transferee if the Certificate formerly representing such shares of Xoom
Stock is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and to evidence that any applicable stock
transfer taxes have been paid.

    2.11  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends or
other distributions declared or made with respect to shares of Class A Common
Stock with a record date after the Effective Time shall be paid to the holder of
any unsurrendered Certificate with respect to the shares of Class A Common Stock
that such holder would be entitled to receive upon surrender of such Certificate
until such holder shall surrender such Certificate in accordance with SECTION
2.10. Subject to the effect of applicable laws, following surrender of any such
Certificate, there shall be paid to such holder of shares of Class A Common
Stock issuable in exchange therefor, without interest, (a) promptly after the
time of such surrender, the amount of dividends or other distributions with a
record date after the Effective Time theretofore paid with respect to such whole
shares of Class A Common Stock, and (b) at the appropriate payment date, the
amount of dividends or other distributions with a record date after the
Effective Time but prior to such surrender and a payment date subsequent to such
surrender payable with respect to such shares of Class A Common Stock.

    2.12  NO FURTHER OWNERSHIP RIGHTS IN XOOM STOCK.  All shares of Class A
Common Stock issued upon surrender of certificates in accordance with the terms
of this ARTICLE II shall be deemed to have been issued in full satisfaction of
all rights pertaining to the shares of Xoom Stock formerly represented thereby.

    2.13  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund which
remains undistributed to the holders of Certificates for six months after the
Effective Time shall be delivered to the Surviving Corporation or otherwise on
the instruction of the Surviving Corporation, and any holders of the
Certificates who have not theretofore complied with this ARTICLE II shall
thereafter look only to Xenon 2 for the Merger Consideration with respect to the
shares of Xoom Stock formerly represented thereby to which such holders are
entitled pursuant to SECTION 2.8 and SECTION 2.10 and any dividends or
distributions with respect to shares of Class A Common Stock to which such
holders are

                                     A-1-8
<PAGE>
entitled pursuant to SECTION 2.11. Any such portion of the Exchange Fund
remaining unclaimed by holders of shares of Xoom Stock five years after the
Effective Time (or such earlier date immediately prior to such time as such
amounts would otherwise escheat to or become property of any Governmental
Entity) shall, to the extent permitted by law, become the property of the
Surviving Corporation free and clear of any claims or interest of any Person
previously entitled thereto.

    2.14  NO LIABILITY.  None of SNAP, CNET, Xenon 2, Xenon 3, Xoom, the
Surviving Corporation or the Exchange Agent shall be liable to any Person in
respect of any Merger Consideration from the Exchange Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

    2.15  LOST CERTIFICATES.  If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the Person claiming
such Certificate to be lost, stolen or destroyed and, if required by Xenon 2,
the posting by such Person of a bond in such reasonable amount as Xenon 2 may
direct as indemnity against any claim that may be made against it with respect
to such Certificate, the Exchange Agent will deliver in exchange for such lost,
stolen or destroyed Certificate the applicable Merger Consideration with respect
to the shares of Xoom Stock formerly represented thereby and unpaid dividends
and distributions on shares of Class A Common Stock deliverable in respect
thereof, pursuant to this Agreement.

    2.16  FURTHER ASSURANCES.  At and after the Effective Time, the officers and
directors of the Surviving Corporation will be authorized to execute and
deliver, in the name and on behalf of Xoom or Xenon 3, any deeds, bills of sale,
assignments or assurances and to take and do, in the name and on behalf of Xoom
or Xenon 3, any other actions and things to vest, perfect or confirm of record
or otherwise in the Surviving Corporation any and all right, title and interest
in, to and under any of the rights, properties or assets acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Merger.

    2.17  STOCK TRANSFER BOOKS.  The stock transfer books of Xoom shall be
closed immediately upon the Effective Time and there shall be no further
registration of transfers of shares of Xoom Stock issued and outstanding
immediately prior to the Effective Time thereafter on the records of Xoom. On or
after the Effective Time, any Certificates presented to the Exchange Agent or
Xenon 2 for any reason shall be canceled and exchanged for certificates
representing the Merger Consideration with respect to the shares of Xoom Stock
formerly represented thereby and any dividends or other distributions to which
the holders thereof are entitled pursuant to SECTION 2.11.

    2.18  FEDERAL INCOME TAX CONSEQUENCES.  For federal income tax purposes, it
is intended that the Merger qualify as a contribution of Xoom Stock to Xenon 2
qualifying under Section 351 of the Code and as a "reorganization," within the
meaning of Section 368(a) of the Code, and that each of Xenon 2, Xoom and Xenon
3 be a "party to a reorganization," within the meaning of Section 368(b) of the
Code, with respect to the Merger.

    material assets or liabilities.

    material respects the financial condition and results of operations of SNAP
    as at December 31, 1998 and for the period then ended, subject to normal
    year-end audit adjustments and financial statement footnote disclosure.
    Except as set forth on SCHEDULE 4.1(g), except as and to the extent
    disclosed in the SNAP Balance Sheet, and except for liabilities incurred in
    connection with the transactions contemplated by this Agreement and the
    Implementing Agreements, there are no liabilities, whether absolute,
    accrued, contingent or otherwise, of SNAP, that would be required to be
    reflected on, or reserved against, in such consolidated balance sheet of
    SNAP, except for (x) liabilities which, singly or in the aggregate, would
    not have a Material Adverse Effect and (y) liabilities incurred subsequent
    to the date of such balance sheet by SNAP in the ordinary course of business
    consistent with past practice.

        (g)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed on
    SCHEDULE 4.1(g) since December 31, 1998, SNAP has conducted its business in
    all material respects only in the ordinary course consistent with past
    practice and there has not been (i) any material adverse change in the
    assets, liabilities, business, results of operations or financial condition
    of SNAP, or (ii) except in the ordinary course of business consistent with
    past practice and except for such matters that would not reasonably be
    expected to have a Material Adverse Effect, any damage, destruction, loss,
    conversion, condemnation or taking by eminent domain related to any of its
    material assets. In addition, except as disclosed on SCHEDULE 4.1(g), from
    December 31, 1998 to the date hereof, SNAP has not (A) acquired or disposed

    SCHEDULE 4.1(h), SNAP has good title to (or, in the case of real estate or
    equipment leases, a valid lease to) all of its properties, assets and other
    rights, free and clear of all Liens except for Permitted Liens and such
    assets will enable Xenon 2 to conduct the business of SNAP after the
    Effective Time in substantially the same manner as it is currently being
    conducted.

        (i)  PROPERTIES, CONTRACTS, PERMITS AND OTHER DATA.  Except as specified
    in SCHEDULE 4.1(i) hereto, all rights, licenses, leases, registrations,
    applications, contracts, commitments and other agreements of SNAP or by
    which SNAP is bound are in full force and effect and are valid and
    enforceable in accordance with their respective terms except for such
    failures to be in full force and effect and valid and enforceable that would
    not, individually or in the aggregate, have a Material Adverse Effect. SNAP
    is not in breach or default in the performance of any obligation thereunder
    and no event has occurred or has failed to occur whereby any of the other
    parties thereto have been or will be released therefrom or will be entitled
    to refuse to perform thereunder, the enforcement of which would have, either
    individually or in the aggregate, a Material Adverse Effect. SNAP has
    provided to Xoom complete and accurate copies of SNAP's current annual
    budget and operating plan (the "SNAP BUDGET").

        (j)  LEGAL PROCEEDINGS.  Except as described in SCHEDULE 4.1(j), there
    is no litigation, proceeding or governmental investigation to which SNAP is
    a party pending or, to the best Knowledge of SNAP, threatened against it or
    its assets which, either individually or in the aggregate, would reasonably
    be expected to result in a Material Adverse Effect or which, as of May 9,
    1999, seeks to restrain or enjoin the consummation of any of the
    transactions contemplated hereby. SNAP is not a party to nor are its assets
    subject to any judgment, writ, decree, injunction or order entered by any
    court or governmental authority (domestic or foreign) that, individually or
    in the aggregate, would reasonably be expected to have a Material Adverse
    Effect.

<PAGE>
        (k)  LABOR CONTROVERSIES.  Except as set forth on SCHEDULE 4.1(k), (i)
    there have been no labor strikes, slow-downs, work stoppages, lock-outs or
    other material labor controversies or disputes during the past two years,

    controversy or dispute pending or, to the best Knowledge of SNAP, threatened
    with respect to the current or former employees of SNAP, (ii) SNAP is not a

    or is in conflict with the Intellectual Property of any third party nor has
    SNAP received any written notice of any claim that it has infringed upon or
    is in conflict with any Intellectual Property of any third party, except as
    would not, individually or in the aggregate, have a Material Adverse Effect.
    Except as set forth on SCHEDULE 4.1(l), none of the rights of SNAP to the
    SNAP Intellectual Property will be impaired in any way by the transactions
    provided for herein, and all of the rights of SNAP to the SNAP Intellectual
    Property will be fully enforceable by SNAP after the Closing Date to the
    same extent as such rights would have been enforceable by SNAP before the
    Closing, without the consent or agreement of any other party other than any
    consents and agreements the failure of which to obtain, individually or in
    the aggregate, would not have a Material Adverse Effect. There have been no
    claims (whether private or governmental) against SNAP asserting the
    invalidity or unenforceability of its ownership, license or other right to
    use any of the registered SNAP Intellectual Property.

        (m)  GOVERNMENT LICENSES, PERMITS, ETC.  Except as set forth on SCHEDULE

        (n)  CONDUCT OF BUSINESS IN COMPLIANCE WITH REGULATORY AND CONTRACTUAL
    REQUIREMENTS.  SNAP has complied with all applicable laws, ordinances,
    regulations or orders or other requirements of any Governmental Authority
    including, without limitation, all rules, regulations and administrative
    orders relating to anti-competitive practices, discrimination, employment,

    not have, either individually or in the aggregate, a Material Adverse
    Effect.

    possessed and complied with all Environmental Permits; (ii) there are and

    any Environmental Law or result in costs arising out of any Environmental
    Law; (iii) no judicial, administrative, or arbitral proceeding (including
    any notice of violation or alleged violation) under any Environmental Law to
    which SNAP is, or to the Knowledge of SNAP will be, named as a party is
    pending or, to the Knowledge of SNAP, threatened, nor is SNAP the subject of
    any investigation in connection with any such proceeding or potential
    proceeding; (iv) there are no past, present, or anticipated future events,
    conditions, circumstances, practices, plans, or legal requirements that

                                     A-1-13
<PAGE>
    obtaining, renewing, or complying with all Environmental Permits required
    under such laws; and (v) SNAP has provided to the other parties true and
    complete copies of all Environmental Reports relating to it in the
    possession or control of such party.

        (p)  EMPLOYEE BENEFIT MATTERS.  (i) SCHEDULE 4.1(p) contains a true and
    complete list of each "employee benefit plan" (within the meaning of section
    3(3) of the Employee Retirement Income Security Act of 1974, as amended
    ("ERISA")), and all stock purchase, stock option, severance, employment,
    change-in-control, fringe benefit, collective bargaining, bonus, incentive,
    deferred compensation and other employee benefit plans, agreements,
    programs, policies or other arrangements, whether or not subject to ERISA
    (including any funding mechanism therefor now in effect or required in the
    future as a result of the transaction contemplated by this Agreement or
    otherwise), whether formal or informal, oral or written, legally binding or
    not, under which any employee or former employee of SNAP or its Subsidiaries
    has any present or future right to benefits and under which SNAP or its
    Subsidiaries has any present or future liability. All such plans,
    agreements, programs, policies and arrangements shall be collectively
    referred to as the "SNAP PLANS".

        (ii) With respect to each SNAP Plan which is maintained solely by SNAP
    (the "SNAP LEVEL PLANS"), SNAP has made available to Xoom and Xenon 2 a
    current, accurate and complete copy (or, to the extent no such copy exists,
    an accurate description) thereof and, to the extent applicable: (A) any
    related trust agreement or other funding instrument; (B) the most recent
    determination letter, if applicable; (C) any summary plan description and
    other written communications (or a description of any oral communications)
    by SNAP or its Subsidiaries to their employees concerning the extent of the

    (I) the Form 5500 and attached schedules and (II) audited financial
    statements.

       (iii) (A) Each SNAP Plan has been established and administered in
    raccordance with its terms, and in compliance with the applicable provisions
    of ERISA, the Code and other applicable laws, rules and regulations; (B)
    each SNAP Plan which is intended to be qualified within the meaning of Code
    section 401(a) is so qualified and has received a favorable determination
    letter as to its qualification (or is established using a prototype plan
    form which has received such a letter), and nothing has occurred, whether by
    action or failure to act, that could reasonably be expected to cause the
    loss of such qualification; (C) for each SNAP Plan with respect to which a
    Form 5500 has been filed, no material change has occurred with respect to
    the matters covered by the most recent Form since the date thereof; (D) no
    non-exempt "prohibited transaction" (as such term is defined in ERISA
    section 406 and Code section 4975) with respect to any SNAP Plan; and (E) no
    SNAP Plan provides retiree welfare benefits and neither SNAP nor its
    Subsidiaries have any obligations to provide any retiree welfare benefits
    except as provided under Section 4980B of the Code.

        (iv) No SNAP Plan is subject to Title IV of ERISA (including a
    multiemployer plan within the meaning of Section 3(37) of ERISA), no SNAP
    Plan is a multiple employer plan; and no SNAP Plan is subject to the minimum
    funding requirements of ERISA Section 302 or Code Section 412.

        (v) Neither SNAP nor any of its Subsidiaries nor any Member of the
    Controlled Group of which it is a member has (A) engaged in, or is a
    successor or parent corporation to an entity that has engaged in, a
    transaction described in Sections 4069 or 4212(c) of ERISA or (B) incurred,
    or could reasonably be expected to incur, any liability under (I) Title IV
    of ERISA arising in connection with the termination of, or a complete or
    partial withdrawal from, any plan covered or previously covered by Title IV
    of ERISA or (II) Section 4971 of the Code that in either case could become a
    liability of SNAP or any Subsidiary or Xenon 2 after the Closing Date. The
    assets of

                                     A-1-14
<PAGE>
    SNAP and all of its Subsidiaries are not now, nor will they after the
    passage of time be, subject to any lien imposed under Code Section 412(n) by
    reason of a failure of any of SNAP or any Subsidiary or any Member of the
    Controlled Group of which it is a member to make timely installments or
    other payments required under Code Section 412.

        (vi) With respect to any SNAP Plan, (A) no actions, suits or claims
    (other than routine claims for benefits in the ordinary course) are pending
    or, to the Knowledge of SNAP or its Subsidiaries, threatened and (B) no
    facts or circumstances exist that could reasonably be expected to give rise
    to any such actions, suits or claims.

       (vii) Except as provided on SCHEDULE 4.1(p), no SNAP Plan exists that
    could result in the payment to any present or former employee of SNAP or its
    Subsidiaries of any money or other property or accelerate or provide any
    other rights or benefits to any present or former employee of SNAP or its
    Subsidiaries as a result of the transaction contemplated by this Agreement,
    whether or not such payment would constitute a parachute payment within the
    meaning of Code Section 280G.

        (q)  ABSENCE OF CERTAIN BUSINESS PRACTICES.  Neither SNAP, nor any
    officer, employee or agent of SNAP, nor any other Person acting on behalf of
    SNAP, has, directly or indirectly, within the past five years given or
    agreed to give any gift or similar benefit to any customer, supplier,
    governmental employee or other Person or entity who is or may be in a
    position to help or hinder SNAP (or assist SNAP in connection with any
    actual or proposed transaction) which (x) subjects any party or any of their
    respective Affiliates, to any damage or penalty in any civil, criminal or
    governmental litigation or proceeding, (y) if not given in the past, could
    have had a Material Adverse Effect or (z) if not continued in the future,
    could have a Material Adverse Effect or which might subject any party or
    Xenon 2 or any of their respective Affiliates to suit or penalty in any
    private or governmental litigation or proceeding.

        (r)  TAX MATTERS.  Except as set forth on SCHEDULE 4.1(r), (i) SNAP and
    its Subsidiaries have timely filed (or have had timely filed on their
    behalf) or will timely file or cause to be timely filed, all Tax Returns
    required by applicable law to be filed by SNAP and its Subsidiaries prior to
    the Effective Time. All such Tax Returns are or will be true, complete and
    correct in all material respects. There are no outstanding agreements or
    waivers extending the statutory period of limitation applicable to any of
    such Tax Returns and SNAP and its Subsidiaries have not requested any
    extension of time within which to file any material Tax Return, which return
    has not yet been filed. There is no pending claim by any Tax Authority of a
    jurisdiction where SNAP or any of its Subsidiaries has not filed Tax Returns
    that SNAP or any of its Subsidiaries are or may have been subject to
    taxation by that jurisdiction. All Taxes required to be withheld by SNAP or
    its Affiliates with respect to their activities, properties, employees or
    independent contractors have been withheld and paid over to the appropriate
    Tax Authority.

        (ii) SNAP and its Subsidiaries have paid (or have had paid on their
    behalf), or where payment is not yet due, have established (or have had
    established on their behalf and for their sole benefit and recourse), or
    will establish or cause to be established on or before the Effective Time,
    an adequate accrual for the payment of, all Taxes due with respect to any
    period beginning prior to the Effective Time. No deficiency or adjustment
    for any Taxes has been threatened, proposed, asserted or assessed against
    SNAP or its Subsidiaries. There are no liens for Taxes upon the assets of
    SNAP or its Subsidiaries, except for liens for current Taxes not yet due.

       (iii) SNAP and its Subsidiaries are not required to include in income any
    adjustment pursuant to Section 481(a) of the Code or any similar applicable
    provision by reason of a voluntary change in accounting method initiated by
    SNAP or its Subsidiaries, and neither the Internal Revenue Service nor any
    taxing authority has proposed in writing any such adjustment or change in
    accounting method. SNAP and its Subsidiaries have not received a tax ruling
    or entered into a

                                     A-1-15
<PAGE>
    closing agreement with any taxing authority that would have a Material
    Adverse Effect on SNAP or its Subsidiaries.

        (iv) SNAP and its Subsidiaries have not made any payments, are not
    obligated to make any payments, and are not a party to any agreement that
    could obligate it to make any payments that would not be deductible pursuant
    to Section 280G of the Code.

        (v) SNAP has been and currently is taxable as a partnership for federal
    income tax purposes and in all jurisdictions in which it is subject to Taxes
    or files Tax Returns. Each of SNAP's Subsidiaries has been and currently is
    (A) wholly owned by SNAP and (B) an entity disregarded from its owner
    pursuant to Section 301.7701-2 of the Treasury Regulations. Neither SNAP nor
    any Subsidiary is a party to any safe harbor lease within the meaning of
    Section 168(f)(8) of the Code, as in effect prior to amendment by the Tax
    Equity and Fiscal Responsibility Act of 1982. SNAP and its Subsidiaries are
    not a party to any joint venture, partnership, or other agreement, contract,
    or arrangement (either in writing or verbally, formally or informally) which
    could be treated as partnership for federal income tax purposes.

        (vi) Neither SNAP nor any of its Subsidiaries has a "permanent
    establishment," as defined in any applicable Tax treaty or convention of the
    United States of America, or fixed place of business in any foreign country.
    SNAP and its Subsidiaries are in compliance with the terms and conditions of
    any applicable tax exemptions, agreements or orders of any foreign
    government to which it may be subject or which it may have claimed, and the
    transactions contemplated by this Agreement will not have any adverse effect
    on such compliance.

       (vii) Neither SNAP nor any of its Subsidiaries is or has been bound by
    any tax sharing or tax allocation agreement, and it has no contractual
    obligation to indemnify any other person with respect to Taxes.

        (s)  YEAR 2000 COMPLIANCE.  SNAP has adopted and implemented a
    commercially reasonable plan to provide (x) that the change of the year from
    1999 to the year 2000 will not have a Material Adverse Effect and (y) that
    the impacts of such change on the venders and customers of SNAP will not
    have a Material Adverse Effect. In SNAP's reasonable best estimate, no
    expenditures materially in excess of currently budgeted items previously
    disclosed to Xoom and Xenon 2 will be required in order to cause the
    information and business systems of SNAP to operate properly following the
    change of the year 1999 to the year 2000. SNAP reasonably expects any
    material issues related to such change of the year will be resolved in
    accordance with the timetable set forth in such plan (and in any event on a
    timely basis in order to be resolved before the year 2000). Between the date
    of this Agreement and the Effective Time, SNAP shall continue to use
    commercially reasonable efforts to implement such plan.

        (t)  OPTIONS.  Except for the SNAP 1998 LLC Option Plan SNAP has never
    adopted or maintained any option plan or other plan providing for equity
    compensation of any Person. SNAP has reserved 1,604,938 units for issuance
    pursuant to the SNAP 1998 LLC Option Plan ("SNAP OPTIONS"), of which
    1,432,970 have been issued as of the date hereof, all of which units remain
    subject to SNAP Options unexercised as of the date hereof. Except as set
    forth in SCHEDULE 4.1(t), none of the SNAP Options will be accelerated in
    any way by the transactions contemplated by this Agreement. SNAP has made
    available to Xoom and Xenon 2 accurate and complete copies of all option
    plans pursuant to which SNAP has granted options and the applicable vesting
    schedule for each such option. All units subject to issuance as aforesaid,
    upon issuance on the terms and conditions specified in the instruments
    pursuant to which they are issuable, would be duly authorized, validly
    issued, fully paid and non-assessable. Except as set forth in SCHEDULE
    4.1(t), there are no commitments or agreements of any character to which
    SNAP is bound obligating SNAP to accelerate the vesting of any SNAP Options
    as a result of this Agreement. SCHEDULE 4.1(e) lists each outstanding SNAP
    Option and identifies with respect to each such SNAP

                                     A-1-16
<PAGE>
    Option; its exercise price; its grant date; its vesting schedule; and what
    portion of such SNAP Option remains outstanding as of the date hereof. SNAP
    shall prepare and deliver to Xenon 2 and Xoom an updated version of SCHEDULE
    4.1(e) prior to the Effective Time as of a date no earlier than 5 days prior
    to the Effective Time.

        (u)  ENTIRE BUSINESS.  Except as set forth in SCHEDULE 4.1(l), SNAP
    owns, is licensed or otherwise has the right to use all the material
    properties and assets, and has all other rights, reasonably necessary for
    the conduct of the business of SNAP as currently conducted.

    business as now conducted by it. Xoom and each of its Subsidiaries party to
    an Implementing Agreement has all requisite power and authority to enter
    into this Agreement, the Voting Agreement, the Option Agreement and the

    qualified to do business and is in good standing in all jurisdictions in
    which it conducts its business, except where the failure to do so would not,
    individually or in the aggregate, taken as a whole, have a Material Adverse
    Effect.

        (b)  AUTHORIZATION AND VALIDITY OF AGREEMENT.  The execution, delivery
    and performance by Xoom and each of its Subsidiaries of this Agreement, the
    Voting Agreement, the Option Agreement and the Implementing Agreements to
    which Xoom or its Subsidiaries is a party and the consummation by Xoom and
    each of its Subsidiaries of the transactions contemplated hereby and thereby
    have been duly authorized by all necessary corporate action on the part of
    Xoom and each of its Subsidiaries, subject to obtaining the affirmative vote
    of the holders of a majority of the outstanding shares of Xoom Stock (the
    "STOCKHOLDER APPROVAL"). The Stockholder Approval is the only vote of the
    holders of any class or series of Xoom's securities necessary to adopt this
    Agreement and approve the transactions contemplated hereby. On or before the
    date hereof, the Board of Directors of Xoom, at a meeting duly called and
    held, by the unanimous vote of the directors present at such meeting and not

    Voting Agreement, and the Merger and the other transactions contemplated
    hereby and thereby, are advisable, (ii) declared the advisability of and
    approved this Agreement, the Option Agreement, the Voting Agreement and each
    of the Implementing Agreements, and (iii) resolved to recommend that the
    holders of shares of Xoom Stock adopt this Agreement and approve the Merger.
    Each of this Agreement, the Option Agreement and the Voting Agreement has
    been, and each of the Implementing Agreements to which Xoom or any of its
    Subsidiaries is a party will on the Closing Date be, duly executed and
    delivered by Xoom and each of its Subsidiaries and constitutes or, in the
    case of the other Implementing Agreements, upon execution thereof will
    constitute, a valid and legally binding obligation of Xoom and its
    Subsidiaries, enforceable against each in accordance with their respective
    terms.

        (c)  GOVERNMENTAL APPROVALS; CONSENTS.  Except as described in SCHEDULE
    4.2(c), the execution, delivery and performance of this Agreement, the
    Voting Agreement, the Option Agreement and the Implementing Agreements by
    Xoom and its Subsidiaries and the consummation by such party of the
    transactions contemplated hereby and thereby will not (i) conflict with or
    result in a breach of any provision of the certificate of incorporation or
    bylaws or other governing documents of Xoom or any of its Subsidiaries; (ii)
    require any consent, approval, authorization or permit of, or filing with or
    notification to, any Governmental Authority; (iii) require the consent or

    lapse of time or both would become a default) or give to any third party any
    right of termination, cancellation, amendment or acceleration under, or
    result in the creation of a Lien on any of the assets of Xoom or its
    Subsidiaries under, any of the terms, conditions or provisions of any
    contract or license to which Xoom or any of its Subsidiaries is a party or
    by which it or its assets or property are bound; or (iv) violate or conflict
    with any order, writ, injunction, decree, statute, rule or regulation
    applicable to Xoom or any of its Subsidiaries; other than any consents,
    approvals, authorizations and permits the failure of which to obtain and any
    violations, conflicts, breaches defaults and other matters set forth
    pursuant to clauses (ii), (iii) and (iv) above which, individually or in the
    aggregate, would not reasonably be expected to have a Material Adverse
    Effect.

        (d)  CERTAIN FEES.  Neither Xoom nor any of its Subsidiaries nor the
    officers, directors or employees thereof have employed any broker or finder
    or incurred any other Liability for any brokerage fees, commissions or
    finders' fees in connection with the transactions contemplated hereby;
    except that Xoom has employed Bear, Stearns & Co., Inc. and Hambrecht &
    Quist, LLC whose fees and expenses will be paid in accordance with SECTION
    10.5 if the transactions contemplated by this Agreement are consummated and
    otherwise will be paid by Xoom. Xoom has provided NBC a copy of the
    engagement letter entered into with Hambrecht & Quist, LLC related to the

    Stock, of which 17,162,056 shares of Xoom Stock and no shares of Xoom
    Preferred Stock have been issued and are outstanding as of the date hereof.
    All outstanding shares of Xoom Stock are duly authorized, validly issued,
    fully paid and non-assessable and not subject to preemptive rights created

    indirectly, any capital stock or other ownership interest in any Person.

        (g)  STOCK OPTIONS.  Except for the Xoom ESPP, the Xoom Option Plan
    pursuant to which the Xoom Plan Options were issued, and the Xoom Non-Plan
    Options (together with the Xoom Plan Options, the "XOOM OPTIONS"), neither

    any class of any equity security of Xoom or any of its Subsidiaries.

        (i)  SEC FILINGS, FINANCIAL INFORMATION, LIABILITIES.  Xoom has filed
    and made publicly available a true and complete copy of each report,
    schedule, registration statement and definitive proxy statement required to
    be filed with the SEC since December 9, 1998 (the "SEC DOCUMENTS"). As of
    their respective dates, the SEC Documents complied in all material respects
    with the requirements of the Securities Act or the Exchange Act, as the case
    may be, applicable to such SEC Documents. None of the SEC Documents when
    filed contained any untrue statement of a material fact or omitted to state
    any material fact required to be stated therein or necessary in order to
    make the statements therein, in light of the circumstances under which they
    were made, not misleading. The financial statements of Xoom included in the
    SEC Documents comply as to form in all material respect with the applicable
    accounting requirements and with the published rules and regulations of the
    SEC with respect thereto, have been prepared in accordance with GAAP during
    the period involved (except as may be indicated in the notes thereto or, in
    the case of the unaudited statements, as permitted by Form 10-Q of the SEC,
    or for normal year-end adjustments) and fairly present in all material
    respects the consolidated financial position of Xoom and its consolidated
    Subsidiaries as at the dates thereof and the consolidated results of their
    operations and cash for the periods then ended. Except as set forth in the
    SEC Documents (including any item accounted for in the financial statements
    contained in the SEC Documents or

                                     A-1-19
<PAGE>
    set forth in the notes thereto) as of December 31, 1998, neither Xoom nor
    any of its Subsidiaries had, and since such date neither Xoom or any of its
    Subsidiaries has incurred, any claims, liabilities or obligations of any
    nature (whether accrued, absolute, contingent or otherwise) which,
    individually or in the aggregate, would have a Material Adverse Effect on
    Xoom (other than claims, liabilities or obligations contemplated by this
    Agreement or expressly permitted to be incurred pursuant to this Agreement).
    In addition, since December 31, 1998, there has not been any declaration,
    setting aside or payment of a dividend or other distribution with respect to
    Xoom Stock or any material change in accounting methods or practices by Xoom
    or any of its Subsidiaries.

        (j)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed on
    SCHEDULE 4.2(j) since December 31, 1998, Xoom and each of its Subsidiaries
    have conducted their businesses in all material respects only in the
    ordinary course, consistent with past practice and there has not been prior
    to the date hereof, (x) any material adverse change in the assets,
    liabilities, business, results of operations or financial condition of Xoom
    or any of its Subsidiaries or (y) except in the ordinary course of business
    consistent with past practice and except for such matters that would not
    reasonably be expected to have a Material Adverse Effect, any damage,
    destruction, loss, conversion, condemnation or taking by eminent domain
    related to any material asset of Xoom and any of its Subsidiaries, taken as
    a whole. In addition, except as disclosed on SCHEDULE 4.2(j), from December
    31, 1998 to the date hereof, neither Xoom nor any of its Subsidiaries has
    (A) acquired or disposed of any material assets or entered into any
    agreement or other arrangement for any such acquisition or disposition or
    (B) relinquished, forgiven or canceled any material debts or claims.

        (k)  PROPERTIES, CONTRACTS, PERMITS AND OTHER DATA.  Except as specified
    in SCHEDULE 4.2(k) hereto, all rights, licenses, leases, registrations,
    applications, contracts, commitments and other agreements of Xoom and its
    Subsidiaries are in full force and effect and are valid and enforceable in
    accordance with their respective terms except for such failures to be in
    full force and effect and valid and enforceable that would not, individually
    or in the aggregate, have a Material Adverse Effect. Neither Xoom nor any of
    its Subsidiaries is in breach or default in the performance of any
    obligation thereunder and no event has occurred or has failed to occur
    whereby any of the other parties thereto have been or will be released
    therefrom or will be entitled to refuse to perform thereunder, the
    enforcement of which would have, either individually or in the aggregate, a
    Material Adverse Effect. Xoom has provided to CNET complete and accurate
    copies of its current annual budget and operating plan (the "XOOM BUDGET").

        (l)  LEGAL PROCEEDINGS.  Except as described in SCHEDULE 4.2(l), there
    is no litigation, proceeding or governmental investigation to which Xoom or
    any of its Subsidiaries is a party pending or, to the best Knowledge of Xoom
    or any of its Subsidiaries, threatened against Xoom or any of its
    Subsidiaries which, either individually or in the aggregate, would
    reasonably be expected to result in a Material Adverse Effect or which, as
    of May 9, 1999, seeks to restrain or enjoin the consummation of any of the
    transactions contemplated hereby. Neither Xoom nor any of its Subsidiaries
    is a party to, nor are any of their respective assets subject to, any
    judgment, writ, decree, injunction or order entered by any court or
    governmental authority (domestic or foreign) that, individually or in the
    aggregate, would reasonably be expected to have a Material Adverse Effect.

        (m)  LABOR CONTROVERSIES.  Except as set forth on SCHEDULE 4.2(m), (i)
    there have been no labor strikes, slow-downs, work stoppages, lock-outs or
    other material labor controversies or disputes during the past two years,
    nor is any such strike, slow-down, work stoppage or other material labor
    controversy or dispute pending or, to the best Knowledge of such party,
    threatened with respect to the current or former employees of Xoom and its
    Subsidiaries, (ii) neither Xoom nor any of its Subsidiaries is a party to
    any labor contract, collective bargaining agreement,

                                     A-1-20
<PAGE>
    contract, letter of understanding or, to such party's Knowledge, any other
    agreement, formal or informal with any labor union or organization, nor are
    any of Xoom's or any of its Subsidiaries' employees represented by any labor
    union or organization nor have there been any labor union organizing
    activities at any Xoom or any of its Subsidiaries' facilities within the
    last three years and (iii) neither Xoom nor any of its Subsidiaries has
    closed any facility, effectuated any layoffs of employees or implemented any
    early retirement, separation or window program within the past two years nor
    has Xoom or any of its Subsidiaries planned or announced any such action or
    program for the future.

        (n)  INTELLECTUAL PROPERTY.  Xoom or its Subsidiaries own or are
    licensed or otherwise have the right to use, all Intellectual Property
    currently used by Xoom and its Subsidiaries (the "XOOM INTELLECTUAL
    PROPERTY"), except as would not, individually or in the aggregate, have a
    Material Adverse Effect. Neither Xoom nor any of its Subsidiaries has
    infringed upon or is in conflict with the Intellectual Property of any third
    party nor has Xoom or any of its Subsidiaries received any written notice of
    any claim that Xoom or any of its Subsidiaries has infringed upon or is in
    conflict with any Intellectual Property of any third party, except as would
    not, individually or in the aggregate, have a Material Adverse Effect.
    Except as set forth on SCHEDULE 4.2(n), none of the rights of Xoom or any of
    its Subsidiaries to the Xoom Intellectual Property will be impaired in any
    way by the transactions provided for herein, and all of the rights of Xoom
    and its Subsidiaries to the Xoom Intellectual Property will be fully
    enforceable by Xenon 2 after the Closing Date to the same extent as such
    rights would have been enforceable by Xoom and its Subsidiaries before the
    Closing, without the consent or agreement of any other party other than any
    consents and agreements the failure of which to obtain, individually or in
    the aggregate, would not have a Material Adverse Effect. There have been no
    claims (whether private or governmental) against Xoom or its Subsidiaries
    asserting the invalidity or unenforceability of its ownership, license or
    other right to use to any of the registered Xoom Intellectual Property.

        (o)  GOVERNMENT LICENSES, PERMITS, ETC.  Except as set forth on SCHEDULE
    4.2(o), Xoom and its Subsidiaries have all licenses, permits, consents,
    approvals, authorizations, qualifications and orders of Governmental
    Authorities required for the conduct of its Business as presently conducted,
    except where failure would not, individually or in the aggregate, have a
    Material Adverse Effect.

        (p)  CONDUCT OF BUSINESS IN COMPLIANCE WITH REGULATORY AND CONTRACTUAL
    REQUIREMENTS.  Xoom and its Subsidiaries have complied with all applicable
    laws, ordinances, regulations or orders or other requirements of any
    Governmental Authority, including, without limitation, all rules,
    regulations and administrative orders relating to anti-competitive
    practices, discrimination, employment, health and safety, except where the
    failure to be in such compliance would not have, either individually or in
    the aggregate, a Material Adverse Effect.

        (q)  EMPLOYEE BENEFIT MATTERS.  (i) SCHEDULE 4.2(q)(i) contains a true
    and complete list of each "employee benefit plan" (within the meaning of
    section 3(3) of ERISA), and all stock purchase, stock option, severance,
    employment, change-in-control, fringe benefit, collective bargaining, bonus,
    incentive, deferred compensation and other employee benefit plans,
    agreements, programs, policies or other arrangements, whether or not subject
    to ERISA (including any funding mechanism therefor now in effect or required
    in the future as a result of the transaction contemplated by this Agreement
    or otherwise), whether formal or informal, oral or written, legally binding
    or not, under which any employee or former employee of Xoom or its
    Subsidiaries has any present or future right to benefits and under which
    Xoom or its Subsidiaries has any present or future liability. All such
    plans, agreements, programs, policies and arrangements shall be collectively
    referred to as the "XOOM PLANS".

        (ii) With respect to each Xoom Plan, Xoom and its Subsidiaries have made
    available to CNET a current, accurate and complete copy (or, to the extent
    no such copy exists, an accurate

                                     A-1-21
<PAGE>
    description) thereof and, to the extent applicable: (A) any related trust
    agreement or other funding instrument; (B) the most recent determination
    letter, if applicable; (C) any summary plan description and other written
    communications (or a description of any oral communications) by Xoom or its
    Subsidiaries to their employees concerning the extent of the benefits
    provided under a Xoom Plan; and (D) for the most recent two years (I) the
    Form 5500 and attached schedules and (II) audited financial statements.

       (iii) (A) Except as set forth on SCHEDULE 4.2(q)(iii), each Xoom Plan has
    been established and administered in accordance with its terms, and in
    compliance with the applicable provisions of ERISA, the Code and other
    applicable laws, rules and regulations; (B) each Xoom Plan which is intended
    to be qualified within the meaning of Code section 401(a) is so qualified
    and has received a favorable determination letter as to its qualification
    (or established using a prototype plan form which has received such a
    letter), and nothing has occurred, whether by action or failure to act, that
    could reasonably be expected to cause the loss of such qualification; (C)
    for each Xoom Plan with respect to which a Form 5500 has been filed, no
    material change has occurred with respect to the matters covered by the most
    recent Form since the date thereof; (D) no nonexempt "prohibited
    transaction" (as such term is defined in ERISA section 406 and Code section
    4975) with respect to any Xoom Plan; and (E) no Xoom Plan provides retiree
    welfare benefits and neither Xoom nor any of its Subsidiaries have any
    obligations to provide any retiree welfare benefits except as provided under
    Section 4980B of the Code.

        (iv) No Xoom Plan is subject to Title IV of ERISA (including a
    multiemployer plan within the meaning of Section 3(37) of ERISA), no Xoom
    Plan is a multiple employer plan; and no Xoom Plan is subject to the minimum
    funding requirements of ERISA Section 302 or Code Section 412.

        (v) Neither Xoom nor any of its Subsidiaries nor any Member of the
    Controlled Group of which it is a member has (A) engaged in, or is a
    successor or parent corporation to an entity that has engaged in, a
    transaction described in Sections 4069 or 4212(c) of ERISA or (B) incurred,
    or could reasonably be expected to incur, any liability under (I) Title IV
    of ERISA arising in connection with the termination of, or a complete or
    partial withdrawal from, any plan covered or previously covered by Title IV
    of ERISA or (II) Section 4971 of the Code that in either case could become a
    liability of Xoom or CNET or any of their respective Subsidiaries after the
    Closing Date. The assets of Xoom and all of its Subsidiaries are not now,
    nor will they after the passage of time be, subject to any lien imposed
    under Code Section 412(n) by reason of a failure of any of any Subsidiary or
    any Member of the Controlled Group of which it is a member to make timely
    installments or other payments required under Code Section 412.

        (vi) With respect to any Xoom Plan, (A) no actions, suits or claims
    (other than routine claims for benefits in the ordinary course) are pending
    or, to the Knowledge of Xoom and its Subsidiaries, threatened and (B) no
    facts or circumstances exist that could reasonably be expected to give rise
    to any such actions, suits or claims.

       (vii) Except as provided on SCHEDULE 4.2(q)(vii), no Xoom Plan exists
    that could result in the payment to any present or former employee of Xoom
    or its Subsidiaries of any money or other property or accelerate or provide
    any other rights or benefits to any present or former employee of Xoom or
    its Subsidiaries as a result of the transaction contemplated by this
    Agreement, whether or not such payment would constitute a parachute payment
    within the meaning of Code Section 280G.

        (r)  ABSENCE OF CERTAIN BUSINESS PRACTICES.  Neither Xoom nor any of its
    Subsidiaries, nor any officer, employee or agent thereof, nor any other
    Person acting on behalf of such Persons, has, directly or indirectly, within
    the past five years given or agreed to give any gift or similar benefit to
    any customer, supplier, governmental employee or other Person or entity who
    is or may be in a

                                     A-1-22
<PAGE>
    position to help or hinder Xoom or its Subsidiaries (or assist Xoom or its
    Subsidiaries in connection with any actual or proposed transaction) which
    (x) subjects any party or any of its Subsidiaries, to any damage or penalty
    in any civil, criminal or governmental litigation or proceeding, (y) if not
    given in the past, could have had a Material Adverse Effect or (z) if not
    continued in the future, could have a Material Adverse Effect or which might
    subject any party or Xenon 2 or any of their respective Subsidiaries to suit
    or penalty in any private or governmental litigation or proceeding.

        (s)  TAX MATTERS.  Except as set forth in SCHEDULE 4.2(s), (i) Xoom and
    each of its Subsidiaries have timely filed (or have had timely filed on
    their behalf) or will timely file or cause to be timely filed, all Tax
    Returns required by applicable law to be filed by any of them prior to the
    Effective Time. All such Tax Returns are or will be true, complete and
    correct in all material respects. There are no outstanding agreements or
    waivers extending the statutory period of limitation applicable to any of
    such Tax Returns and neither Xoom nor any of its Subsidiaries has requested
    any extension of time within which to file any material Tax Return, which
    return has not yet been filed. There is no pending claim by any tax
    authority of a jurisdiction where Xoom or any of its Subsidiaries has not
    filed Tax Returns that Xoom or such Subsidiary is or may have been subject
    to taxation by that jurisdiction. All Taxes required to be withheld by Xoom
    or its Affiliates with respect to their activities, properties, employees or
    independent contractors have been withheld and paid over to the appropriate
    Tax Authority.

        (ii) Xoom and each of its Subsidiaries have paid (or have had paid on
    their behalf), or where payment is not yet due, have established (or have
    had established on their behalf and for their sole benefit and recourse), or
    will establish or cause to be established on or before the Effective Time,
    an adequate accrual for the payment of, all Taxes due with respect to any
    period beginning prior to the Effective Time. No deficiency or adjustment
    for any Taxes has been threatened, proposed, asserted or assessed against
    Xoom or any of its Subsidiaries. There are no liens for Taxes upon the
    assets of Xoom or any of its Subsidiaries, except for liens for current
    Taxes not yet due.

       (iii) Neither Xoom nor any of its Subsidiaries is required to include in
    income any adjustment pursuant to Section 481(a) of the Code or any similar
    applicable provision by reason of a voluntary change in accounting method
    initiated by Xoom or any of its Subsidiaries, and neither the Internal
    Revenue Service nor any taxing authority has proposed in writing any such
    adjustment or change in accounting method. Neither Xoom nor any of its
    Subsidiaries has received a tax ruling or entered into a closing agreement
    with any taxing authority that would have a continuing Material Adverse
    Effect upon Xoom or any of its Subsidiaries.

        (iv) Neither Xoom nor any of its Subsidiaries has made any payments, is
    obligated to make any payments, or is a party to any agreement that could
    obligate it to make any payments that would not be deductible pursuant to
    Section 280G of the Code.

        (v) Neither Xoom nor any of its Subsidiaries has a "permanent
    establishment," as defined in any applicable Tax treaty or convention of the
    United States of America, or fixed place of business in any foreign country.
    Xoom and its Affiliates are in compliance with the terms and conditions of
    any applicable tax exemptions, agreements or orders of any foreign
    government to which it may be subject or which it may have claimed, and the
    transactions contemplated by this Agreement will not have any adverse effect
    on such compliance.

        (vi) Neither Xoom nor any Subsidiary is a party to any safe harbor lease
    within the meaning of Section 168(f)(8) of the Code, as in effect prior to
    amendment by the Tax Equity and Fiscal Responsibility Act of 1982. Xoom and
    its Subsidiaries are not a party to any joint venture, partnership, or other
    agreement, contract, or arrangement (either in writing or verbally, formally
    or informally) which could be treated as partnership for federal income tax
    purposes.

                                     A-1-23
<PAGE>
       (vii) Neither Xoom nor any of its Subsidiaries is or has been bound by
    any tax sharing or tax allocation agreement, and it has no contractual
    obligation to indemnify any other person with respect to Taxes.

        (t)  SECTION 203.  The Board of Directors of Xoom and each of its
    Subsidiaries has taken appropriate action so that the provisions of Section
    203 of the DGCL restricting "business combinations" with "interested
    stockholders" (each as defined in such Section 203) will not, prior to the
    termination of this Agreement pursuant to ARTICLE IX hereof, apply to CNET
    or SNAP or any of their Affiliates with respect to this Agreement, the NMC
    Merger Agreement, the Voting Agreement, the Option Agreement or any of the
    Implementing Agreements or any of the transactions contemplated hereby or
    thereby.

        (u)  YEAR 2000 COMPLIANCE.  Except as set forth in SCHEDULE 4.2(v),
    Xoom, and each of its Subsidiaries has adopted and implemented a
    commercially reasonable plan to provide (x) that the change of the year from
    1999 to the year 2000 will not have a Material Adverse Effect and (y) that
    the impacts of such change on the venders and customers of Xoom and each of
    its Subsidiaries will not have a Material Adverse Effect. In the reasonable
    best estimate of Xoom and each of its Subsidiaries, no expenditures
    materially in excess of currently budgeted items previously disclosed to
    CNET will be required in order to cause the information and business systems
    of Xoom and each of its Subsidiaries to operate properly following the
    change of the year 1999 to the year 2000. Xoom and each of its Subsidiaries
    reasonably expects any material issues related to such change of the year
    will be resolved in accordance with the timetable set forth in such plan
    (and in any event on a timely basis in order to be resolved before the year
    2000). Between the date of this Agreement and the Effective Time, Xoom and
    each of its Subsidiaries shall continue to use commercially reasonable
    efforts to implement such plan.

        (v)  NO BUSINESS ACTIVITIES.  Neither Xenon 2 nor Xenon 3 has conducted
    any activities other than in connection with their organization, the
    negotiation and execution of this Agreement and the NMC Merger Agreement and
    the consummation of the transactions contemplated hereby and thereby.

    4.3  REPRESENTATIONS AND WARRANTIES WITH RESPECT TO CNET.  CNET represents
and warrants to Xoom as follows:

        (a)  DUE ORGANIZATION, POWER AND GOOD STANDING.  CNET is duly organized,
    validly existing and in good standing under the laws of its jurisdiction of
    organization, and has the requisite power and authority to own, lease and
    operate its properties and to conduct its business as now conducted by it.
    CNET has all requisite power and authority to enter into this Agreement and
    the Implementing Agreements to which it is a party and to perform its
    obligations hereunder and thereunder. CNET is qualified to do business and
    is in good standing in all jurisdictions in which it conducts its business,
    except where the failure to do so would not, individually or in the
    aggregate, taken as a whole, have a Material Adverse Effect.

        (b)  AUTHORIZATION AND VALIDITY OF AGREEMENT.  The execution, delivery
    and performance by CNET of this Agreement and the Implementing Agreements to
    which it is a party and the consummation by CNET of the transactions
    contemplated hereby and thereby have been duly authorized by all necessary
    corporate action on the part of CNET. No vote of the holders of any class or
    series of CNET's securities is necessary to approve this Agreement and the
    transactions contemplated hereby. This Agreement has been, and each of the
    other Implementing Agreements to which CNET is a party will on the Closing
    Date be, duly executed and delivered by CNET and constitutes or, in the case
    of the Implementing Agreements, upon execution thereof will constitute, a
    valid and legally binding obligation of CNET enforceable against it in
    accordance with its terms.

    under the SNAP LLC Agreement and except as described in SCHEDULE 4.3(c), the
    execution, delivery and performance of this Agreement and the Implementing
    Agreements to which it is a party by CNET and the consummation by it of the
    transactions contemplated hereby and thereby will not (i) conflict with or
    result in a breach of any provision of the certificate of incorporation or
    bylaws of CNET; (ii) require any consent, approval, authorization or permit
    of, or filing with or notification to, any Governmental Authority; (iii)

    of termination, cancellation, amendment or acceleration under, any of the
    terms, conditions or provisions of any contract or license to which CNET is
    a party or by which it or its assets or property are bound; or (iv) violate
    or conflict with any order, writ, injunction, decree, statute, rule or
    regulation applicable to CNET; other than any consents, approvals,
    authorizations and permits the failure of which to obtain and any
    violations, conflicts, breaches defaults and other matters set forth
    pursuant to clauses (ii), (iii) and (iv) above which, individually or in the
    aggregate, would not reasonably be expected to have a Material Adverse
    Effect.

        (d)  CERTAIN FEES.  Neither CNET or any of its Subsidiaries nor the
    officers, directors or employees, thereof have employed any broker or finder
    or incurred any other Liability for any brokerage fees, commissions or

    except that CNET has employed and will pay all fees and expenses of Morgan
    Stanley & Co. Incorporated incurred on its behalf.

        (e)  TITLE TO PROPERTIES; ABSENCE OF LIENS.  CNET has, and at the
    Closing Xenon 2 will acquire, good title to all of the SNAP Units held by
    CNET (which represent approximately 81% of the outstanding SNAP Units as of
    the date hereof), free and clear of all Liens (other than Liens created,
    imposed or granted by Xenon 2 and as set forth in the SNAP LLC Agreement).

        (f)  ACCREDITED INVESTOR.  CNET is an "accredited investor" within the
    meaning of Rule 501 of Regulation D under the Securities Act. CNET (i) is

    not with a view to, or for sale in connection with, any distribution
    thereof, in violation of the Securities Act; (ii) has had an opportunity to

    information concerning, Xenon 2 and its Subsidiaries; (iii) has knowledge,
    sophistication and experience in business and financial matters and risks of
    such investment; (iv) is able to bear the economic risk of such investment;
    and (v) is able to afford a complete loss of such investment.

        (g)  LEGAL PROCEEDINGS.  Except as described in CNET's periodic reports
    and other filings with the SEC, there is no litigation, proceeding or
    governmental investigation to which CNET or its Subsidiaries is a party
    pending or, to the best Knowledge of CNET, threatened against it or its
    Subsidiaries which, either individually or in the aggregate, would
    reasonably be expected to result in a Material Adverse Effect or which, as
    of May 9, 1999, seeks to restrain or enjoin the consummation of any of the
    transactions contemplated hereby. CNET is not a party to nor are its assets
    subject to any judgment, writ, decree, injunction or order entered by any
    court or governmental authority (domestic or foreign) that, individually or
    in the aggregate, would reasonably be expected to have a Material Adverse
    Effect.

certificates delivered pursuant to ARTICLE VII shall survive the Closing.

                                     A-1-25

    4.5  NO OTHER REPRESENTATION OR AND WARRANTIES.  Except for the

                  CONDUCT OF BUSINESS PRIOR TO EFFECTIVE TIME

    5.1  CONDUCT OF THE BUSINESS OF XOOM PENDING THE CLOSING.  Xoom agrees that
except with the prior written consent of CNET (PROVIDED that if NBC has
consented to any Xoom action under the NMC Merger Agreement, Xoom shall not be
required to get CNET's consent under this Agreement to take the same action) and
except as may be expressly permitted by this Agreement or as set forth on
SCHEDULE 5.1, prior to the Closing, it shall, and shall cause, its Subsidiaries
to operate their businesses only in the usual, regular and ordinary manner, on a
basis consistent with past practice and, to the extent consistent with such
operation, use its reasonable efforts to preserve its present business
organization intact, keep available the services of its present employees,
preserve its present business relationships (consistent with past practice) and
maintain all rights, privileges and franchises in the normal conduct of Xoom's
businesses. Without limitation of the foregoing, from the date hereof until the

    into, or rights, warrants or options to acquire, any such shares of other
    convertible securities other than (i) issuances of Xoom Stock pursuant to
    Xoom Options outstanding on the date hereof, the Option Agreement or the
    obligations to issue Xoom Stock set forth on SCHEDULE 4.2(h) and (ii)(x)

    employees currently holding Xoom Plan Options exercisable in the aggregate
    for not more than that number of shares of Xoom Stock that equals 15% of the
    shares of Xoom Stock for which Xoom Plan Options will remain unvested and
    nonexercisable after giving effect to the acceleration of vesting described
    in SECTION 6.8 of the NMC Merger Agreement; and (y) Xoom Options with an
    exercise price of not less than 85% of the fair market value on the date of
    grant, and vesting over not less than 3 years, to be issued to employees
    currently holding Xoom Non-Plan Options exercisable in the aggregate for not
    more than the lesser of (i) that number of shares of Xoom that equals two
    times the number of shares of Xoom for which Xoom Non-Plan Options will
    remain unvested and nonexercisable and terminate after giving effect to the
    acceleration of vesting described in SECTION 6.8 of the NMC Merger Agreement
    or (ii) 150,000 shares of Xoom.

    consideration not in excess of $10,000,000 individually or $25,000,000 in
    the aggregate taken together with all such acquisitions.

        (e) dispose of any business or any assets (other than inventory and any
    other assets acquired solely for use in an existing business in the ordinary
    course consistent with past practice of such business) or dispose of any

to afford the officers, employees, auditors and other agents of CNET and Xoom
reasonable access during normal business hours to the officers, employees,

contracts, commitments, books, records and Tax Returns relating thereto, and
shall use reasonable efforts to furnish such Persons all such documents and such
financial, operating and other data and information regarding such businesses
and Persons that are in the possession of such Person as CNET or Xoom, as
applicable, through their respective officers, employees or agents may from time
to time reasonably request. All such information, as well as any information
provided prior to the date hereof, shall be used only for the purposes of the
transactions contemplated hereby and, unless required by subpoena or otherwise

    5.5  AMENDMENTS TO SCHEDULES.  If no later than five business days prior to
the Closing Date, Xoom, SNAP or CNET becomes aware of any fact or circumstance
(whether or not it existed prior to the date hereof) which would make any
representation, warranty, covenant or agreement of such party untrue, then such
party shall be permitted to amend any Schedule to this Agreement so as to
identify such fact or circumstance to the extent necessary to make such
representation, warranty, covenant or agreement true and correct; PROVIDED that
if any such amendment, individually or in the aggregate with all such other
amendments, discloses facts and circumstances that constitute a Material Adverse
Effect, then notwithstanding anything to the contrary in this Agreement, the
other party (which shall be Xoom in the case of amendments by SNAP or CNET and
shall be CNET in the case of amendments by Xoom) shall have the right to
terminate this Agreement. Notwithstanding the foregoing, any change to a
Schedule that refers solely to an item previously disclosed in the SEC Documents
shall not be deemed to have a Material Adverse Effect on Xoom if such reference
is to a specific section of a specific SEC Document.

                                   ARTICLE VI
                                OTHER AGREEMENTS

    6.1  REGISTRATION STATEMENT; PREPARATION OF PROXY STATEMENT.  (a) As soon as
practicable after the execution of this Agreement, Xoom shall prepare and cause
to be filed with the SEC preliminary proxy materials (the "PROXY STATEMENT") for
the solicitation of approval by the stockholders of Xoom of this Agreement, the
Merger and the other transactions contemplated hereby and pursuant to the
Implementing Agreements as may reasonably require approval of Xoom's
stockholders. Xoom shall cause Xenon 2 to prepare and cause to be filed with the
SEC a registration statement on Form S-4 (the "FORM S-4"), in which the Proxy
Statement will be included as a prospectus, with respect to those shares of
Class A Common Stock issuable pursuant to the transactions contemplated hereby.
Xoom shall cause the Form S-4 and the Proxy Statement related thereto to comply
with applicable law and the rules and regulations promulgated by the SEC, to
respond promptly to any comments of the SEC or its staff and to have such
registration statement declared effective under the Securities Act as promptly
as practicable after it is filed with the SEC and Xoom shall use its best
efforts to cause the proxy statement to be mailed to Xoom's stockholders as
promptly as practicable after the registration statement is declared effective
under the Securities Act. Each of the parties hereto shall promptly furnish to
the other party all information concerning itself, its stockholders and its
Affiliates that may be required or reasonably requested in connection with any
action contemplated by this SECTION 6.1. If any event relating to any party
occurs, or if any party becomes aware of any information, that should be
disclosed in an amendment or supplement to the Form S-4 or the Proxy Statement,
then such party shall inform the other thereof and shall cooperate with each
other in filing such amendment or supplement with the SEC and, if appropriate,
in mailing such amendment or supplement to the stockholders of Xoom. The Proxy
Statement shall include the recommendation of the Board of Directors of Xoom in
favor of the adoption of this Agreement and the approval of the transactions
contemplated hereby.

    (b) Prior to the Effective Time, Xoom shall cause Xenon 2 to use reasonable
efforts to obtain all regulatory approvals needed to ensure that the Class A
Common Stock to be issued in connection with the transactions contemplated
hereby: (i) will be registered or qualified under the "blue sky" laws of every
jurisdiction of the United States in which any registered holder of the
outstanding Xoom Stock who is receiving registered shares of Class A Common
Stock has an address of record or be exempt from such registration; and (ii)
will be approved for quotation at the Effective Time on Nasdaq.

    (c) Each of Xoom, and CNET agrees with respect to the information to be
supplied by such party that: (i) none of the information to be supplied by such
party or its Affiliates for inclusion in the Form S-4 will, at the time the Form
S-4 becomes effective under the Securities Act, contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or

                                     A-1-30
<PAGE>
necessary in order to make the statements therein, in light of the circumstances
under which they are made, not misleading; (ii) none of the information to be
supplied by such party or its Affiliates for inclusion in the Proxy Statement
will, at the time the Proxy Statement is mailed to the stockholders of Xoom or
as of the Effective Time, contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading; and (iii) as to matters respecting such party,
the Proxy Statement and the Form S-4 will comply as to form in all material
respects with the provisions of the Securities Act and the Exchange Act, as
applicable, and the rules and regulations promulgated by the SEC thereunder.

    6.2  STOCKHOLDER MEETING.  Xoom shall promptly after the date hereof take
all action necessary in accordance with applicable law and its certificate of
incorporation and bylaws to duly call, hold and convene a meeting of Xoom's
stockholders (the "STOCKHOLDER MEETING"). Except as required by the SEC or
applicable court order, Xoom shall not postpone or adjourn (other than for the
absence of a quorum) the Stockholder Meeting without the consent of CNET and
SNAP. Neither CNET nor Xoom shall in any way challenge the validity,
enforceability or effectiveness of the voting agreements or proxies entered into
by certain stockholders of Xoom in connection with the Merger and the
transactions contemplated hereby. Xoom shall take all other action necessary or
advisable to secure the Stockholder Approval, subject to its right to terminate
the Agreement under SECTION 9.1(f). Xenon 2 shall, through its Board of
Directors, recommend to its stockholders the approval and adoption of this
Agreement, the Merger and the other transactions contemplated hereby, unless
prior to obtaining the Xoom Stockholder Approval its Board of Directors
determines in good faith based on the advice of outside legal counsel that the
withdrawal or modification, in a manner adverse to CNET, of its approval and
adoption of this Agreement is required in order to comply with its fiduciary
duties under applicable law and Xenon 2 simultaneously terminates this Agreement
pursuant to SECTION 9.1(f).

    6.3  PUBLIC STATEMENTS.  Before any party or any Affiliate of such party
shall release any information concerning this Agreement or the matters
contemplated hereby which is intended for or may result in public dissemination
thereof, such party shall cooperate with the other parties, shall furnish drafts
of all documents or proposed oral statements to the other parties, provide the
other parties the opportunity to review and comment upon any such documents or
statements and shall not release or permit release of any such information
without the consent of the other parties, except to the extent required by
applicable law or the rules of any securities exchange or automated quotation
system on which its securities or those of its Affiliate are traded.

    6.4  REASONABLE COMMERCIAL EFFORTS.  (a) Subject to the terms and conditions
provided in this Agreement, each party shall use reasonable commercial efforts
to take promptly, or cause to be taken, all actions, and to do promptly, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to consummate and make effective the transactions
contemplated hereby, to obtain all necessary waivers, consents and approvals and
to effect all necessary registrations and filings, including, without
limitation, an appropriate filing of a Notification and Report Form pursuant to
the HSR Act with respect to the transactions contemplated hereby (PROVIDED,
HOWEVER, in no event shall CNET be responsible or obligated to pay any filing
fees in connection therewith (and all such fees will be paid by Xoom)), and the
filings and consents set forth on SCHEDULE 6.4 hereto (the "REQUIRED CONSENTS")
and to remove any injunctions or other impediments or delays, legal or
otherwise, in order to consummate and make effective the transactions
contemplated by this Agreement for the purpose of securing to the parties hereto
the benefits contemplated by this Agreement; PROVIDED that notwithstanding
anything to the contrary in this Agreement, no party nor any of their Affiliates
shall be required to make any disposition, including, without limitation, any
disposition of, or any agreement to hold separate, any Subsidiary, asset or
business, and no party hereto nor any of their Affiliates shall be required to
make any payment of money nor shall any party or its Affiliates be required to
comply with any condition or undertaking or take any action which, individually
or in the aggregate, would

                                     A-1-31
<PAGE>
materially adversely affect the economic benefits to such party of the
transactions contemplated hereby and the Implementing Agreements, taken as a
whole or adversely affect any other business of such party or its Affiliates.

    (b) Each of the parties hereto shall execute and cause its Subsidiaries to
execute on or prior to the Closing Date each Implementing Agreement to which it
or they are a party on the terms set forth in the relevant Exhibits hereto.

    (c) Each of the parties hereto agrees, from time to time, to execute and
deliver, or use reasonable commercial efforts to cause to be executed and
delivered, such additional instruments, certificates or documents (including
bills of sale and assignment and assumption agreements), and take all such
actions, reasonably necessary to implement or effectuate the transactions
contemplated by this Agreement.

    6.5  NOTIFICATION OF CERTAIN MATTERS.  Each party to this Agreement shall
give prompt notice to each other party of (i) the occurrence or non-occurrence
of any event, the occurrence or non-occurrence of which is likely to cause any
representation or warranty of any party contained in this Agreement to be untrue
or inaccurate at or prior to the Effective Time and (ii) any failure of any
party to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery
of any notice pursuant to this SECTION 6.5 shall not limit or otherwise affect
any remedies available to the parties receiving such notice. No disclosure by
any party pursuant to this SECTION 6.5, however, shall be deemed to amend or
supplement the disclosures set forth on the Schedules to ARTICLE IV or prevent
or cure any misrepresentations, breach of warranty or breach of covenant.

    6.6  XENON 2 DIRECTORS  Xenon 2 will cause the Surviving Corporation to
indemnify each person who is now, or has been at any time prior to the date of
this Agreement, or who becomes prior to the Effective Time, a director or
officer of Xoom and any of its Subsidiaries from and after the Effective Time
(individually an "INDEMNIFIED PARTY" and collectively the "INDEMNIFIED
PARTIES"), with respect to acts or omissions occurring prior to the Effective
Time to the full extent provided as of the date hereof under the certificate of
incorporation, bylaws, other similar organizational documents of Xoom or
applicable law. Xenon 2 shall cause the Surviving Corporation to maintain the
current policies of the officers' and directors' liability insurance maintained
by Xoom for at least six years, PROVIDED that the Surviving Corporation shall
not be required to expend in any one year an amount in excess of 200% of the
annual premiums currently paid by Xoom for such insurance. The rights under this
SECTION 6.6 are contingent upon the occurrence of, and will survive consummation
of, the transactions contemplated hereby and are expressly intended to benefit
each Indemnified Party each of whom shall have third party beneficiary rights
hereunder.

    6.7  EMPLOYEE MATTERS.

        (a)  EMPLOYEE BENEFIT PLANS.

        (i) As of the Closing Date, the employees of SNAP (the "SNAP EMPLOYEES")
    shall cease to accrue further benefits under the SNAP Plans (other than the
    SNAP Level Plans) and shall immediately commence participation in the Xenon
    2 Plans (which shall initially be the Xoom Plans) (other than Xoom Plans
    comparable to the SNAP Level Plans) on a basis no less favorable than
    similarly situated employees of Xenon 2 or Xoom. Xenon 2 or Xoom shall cause
    each Xenon 2 Plan to treat the prior service of each SNAP Employee with SNAP
    or its affiliates as service rendered to Xenon 2 or Xoom for purposes of
    eligibility, vesting and benefit accruals (but not for purposes of benefit
    accruals under any defined benefit pension plan) to the same extent such
    service was taken into consideration under comparable SNAP Plans.

        (ii) CNET shall retain all assets and liabilities and obligations under
    SNAP Plans (other than the SNAP Level Plans) with respect to the SNAP
    Employees.

                                     A-1-32
<PAGE>
        (b)  SNAP EMPLOYEE OPTIONS

        SNAP and Xenon 2 will take all requisite corporate action such that, as
    of the Closing Date,

        (i) each outstanding option to purchase SNAP units (a "SNAP OPTION")
    held by a SNAP Employee that was issued before May 9, 1999, and each
    outstanding SNAP Option held by a SNAP Employee that was issued after May 9,
    1999 pursuant to a job offer that was extended before May 9, 1999, as
    identified on SCHEDULE 4.1(T) as amended, shall be converted into a stock
    option to purchase a number of shares of Xenon 2 (a "XENON 2 OPTION") equal
    to 1.2853 times the number of shares of SNAP to which the SNAP Option
    pertains; and

        (ii) each outstanding option to purchase a SNAP Option held by a SNAP
    Employee that was issued on or after May 9, 1999 (other than pursuant to a
    job offer that was extended before May 9, 1999, as identified on SCHEDULE
    4.1(T) as amended) shall be converted on a one-for-one basis into a Xenon 2
    Option to purchase a number of shares of Xenon 2 equal to the number of
    units of SNAP to which the SNAP Option pertains.

        The per share exercise price of each such Xenon 2 Option shall equal the
    aggregate exercise price of the corresponding SNAP Option divided by the
    exchange ratio used to convert such corresponding Snap Option into such
    Xenon 2 Option (I.E., either 1.2853:1 or 1:1, as the case may be). The
    vesting schedule of such Xenon 2 Option shall be on a monthly basis, and
    otherwise consistent with the vesting schedule of the corresponding SNAP
    Option, except that in the case of the Xenon 2 Options issued pursuant to
    (i) above, the vesting shall be accelerated by 12 months (in accordance with
    the resolution of Snap's Board of Managers dated June 24, 1999), when
    compared with the corresponding SNAP Option.

    6.8  XOOM OPTIONS.  (a) Prior to the Effective Time, Xenon 2 shall adopt,
and the stockholders of Xenon 2 shall approve, a stock option plan (the "XENON 2
OPTION PLAN") providing for the issuance of "incentive stock options" (within
the meaning of Section 422 of the Code) and nonqualified options. At the
Effective Time, each outstanding Xoom Option shall be converted into an option
(each a "XENON 2 OPTION") of Xenon 2 to purchase shares of Class A Common Stock
under the Xenon 2 Option Plan or through assumption by Xenon 2 of the Xoom
Option Plan and each Xoom Non-Plan Option Agreement, as provided below.
Following the Effective Time, each such Xenon 2 Option shall be exercisable upon
the same terms and conditions as were applicable to the related Xoom Option as
in effect immediately prior to the Effective Time, except that (i) each such
Xenon 2 Option shall be exercisable for that number of shares of Class A Common
Stock equal to the number of shares of Xoom Stock that were issuable upon
exercise in full of such converted Xoom Option immediately prior to the
Effective Time and (ii) the per share exercise price for the shares of Class A
Common Stock issuable upon exercise of such Xenon 2 Option shall be equal to the
exercise price per share of Xoom Stock at which such Xoom Option was exercisable
immediately prior to the Effective Time. It is the intention of the parties
that, to the extent that any such Xoom Plan Option constituted an "incentive
stock option" (within the meaning of Section 422 of the Code) immediately prior
to the Effective Time, such option shall continue to qualify as an incentive
stock option to the maximum extent permitted by Section 422 of the Code, and
that the conversion of the Xoom Plan Options provided by this SECTION 6.8(a)
satisfy the conditions of Section 424(a) of the Code.

    (b) Xoom represents and warrants that as of the date hereof there are no,
and have not previously been any, participants in the Xoom 1998 Employee Stock
Purchase Plan (the "XOOM ESPP"). Xoom agrees that it shall take any necessary
action to prohibit any participation in the Xoom ESPP in the future and to
terminate the Xoom ESSP prior to the Effective Time.

    6.9  RELEASE OF CNET'S GUARANTEE.  Xenon 2 shall use its reasonable best
efforts to cause the guarantee by CNET of SNAP's obligations under Office Lease,
dated September 24, 1997, as amended,

                                     A-1-33
<PAGE>
between No. 1 Beach Street LLC and CNET, to be released as soon as practicable
following the Closing.

    6.10  RESIGNATION OF SNAP'S CEO.  CNET will cause the Chief Executive
Officer of SNAP to resign from such position as of the Effective Time.

    6.11  TAX COOPERATION AND CONSISTENT REPORTING.

    To the extent CNET has it:

        (a) Xoom and CNET agree to furnish or cause to be furnished to each
    other, upon request, as promptly as practicable, such information and
    assistance relating to the Contributed Assets as is reasonably necessary for
    the filing of all Tax Returns, and making of any election related to Taxes,
    the preparation for any audit by any Tax Authority, and the prosecution or
    defense of any claim, suit or proceeding relating to any Tax Return to the
    extent, in the case of CNET, such information is reasonably available to
    CNET. Xoom and CNET will cooperate with each other in the conduct of any
    audit or other proceeding related to Taxes and all other Tax matters
    relating to the Contributed Assets, and each will execute and deliver such
    powers of attorney and other documents as are necessary to carry out the
    intent of this SECTION 6.11.

        (b) Unless there has been a Final Determination to the contrary, Xoom
    and CNET covenant and agree, for all Tax purposes including all Tax Returns
    and any Tax controversies to (and to cause any Affiliate or successor to
    their assets or business to) take each of the positions set forth below (and
    not to take any positions inconsistent therewith):

            (i) The transfer of the Contributed Assets pursuant to the Agreement
       will qualify under Section 351(a) of the Code, the Merger will constitute
       a "reorganization", within the meaning of Section 368(a) of the Code, the
       each of Xoom, Xenon 2 and Xenon 3 will be treated as a "party to a
       reorganization", within the meaning of Section 368(b) of the Code, with
       respect to the Merger.

            (ii) None of the consideration received for the Contributed Assets
       pursuant to the Agreement will be treated as Other Property or Money.

           (iii) None of the Class A Common Stock issued to CNET pursuant to the
       terms of the Agreement will be paid or issued for services.

            (iv) The tax basis of each Contributed Asset to be received by Xenon
       2 will be the same as the tax basis of such asset in the hands of the
       transferor increased by the amount of any gain recognized by the
       transferor on the transfer of such asset.

            (v) The holding period of each Contributed Asset will include the
       period during which such asset was held by the transferor.

            (vi) Neither Xoom or Xenon 2, any affiliate thereof, nor any
       successor to their assets or businesses will be entitled to claim any
       deduction in respect of any Assumed Liability to the extent previously
       deducted by the transferor.

        (c) Xenon 2 represents, covenants and agrees that (A) it has no plan or
    intention to (i) cause Xoom to issue additional shares of stock after the
    Merger, or take any other action, that would result in Xenon 2 losing
    control of Xoom, (ii) liquidate Xoom or merge Xoom with Xenon 2 or into any
    other corporation; (iii) cause Xoom to sell or otherwise dispose of any of
    its assets (or of any of the assets acquired from Xenon 3), except for
    dispositions made in the ordinary course of business, transfers permitted
    under Section 368(a)(2)(C) of the Code, or transfers prescribed by Section
    1.368-1(d) that will not affect satisfaction of the "continuity of business
    enterprise" requirement under Section 368 of the Code for purposes of
    qualifying the Merger as a "reorganization" under said section, or (iv)
    reacquire any of the shares of its stock issued pursuant

                                     A-1-34
<PAGE>
    to this Agreement, and (B) the historic business of Xoom will be continued
    or a significant portion of Xoom's historic business assets will be used in
    a business.

        (d) (i) Xoom, Xenon 2 and CNET agree to report to each other any
    communication from or with the Internal Revenue Service which relates in any
    way to the characterization of the transactions contemplated by the
    Agreement. Notwithstanding any such communication, Xoom, Xenon 2 and CNET
    covenant and agree to (and to cause any Affiliate or successor to their
    assets or business to) continue to take each of the positions specified in
    SECTION 6.11(b) for all Tax purposes (unless there has been a Final
    Determination contrary to such position).

        (ii) Without limiting the generality of SECTION 6.11(d)(i), (A) Xoom
    will use its best efforts to cause each Xoom stockholder to file, and CNET
    will file, with its federal income tax return for the taxable year in which
    the Agreement is consummated (which CNET tax return shall be timely filed)
    the information required by Treas. Reg Section1.351-3(a) (PROVIDED that, in
    the case of Xoom, such best efforts shall only require Xoom to advise its
    stockholders of the requirement to comply with said section of the Treasury
    Regulations and to provide them with draft language for the Required
    Statement), and CNET will deliver a copy of that statement to Xenon 2 within
    ten days thereafter, and (B) Xenon 2 will file with its federal income tax
    return for the taxable year in which the Agreement is consummated (which tax
    return shall be timely filed) the information required by Treas. Reg
    Section1.351-3(b), and will deliver a copy of that statement to CNET within
    ten days thereafter. Within ninety days after the Closing Date, CNET will
    deliver to Xenon 2 all of the cost and other basis information relating to
    the Contributed Assets and assumed Liabilities for federal income tax
    purposes reasonably required for Xenon 2 to prepare the statement required
    by Treas. Reg. Section1.351-3(b)(2). Such information will be delivered in
    the form normally maintained by CNET and will include reasonably complete
    data relating to the tax basis, year of acquisition, depreciable life, and
    amount and method of depreciation of tangible and intangible property. Xenon
    2 and CNET also will maintain such records as are required by Treas. Reg.
    Section1.351-3(c).

       (iii) Without limiting the generality of SECTION 6.11(d)(i), (A) Xoom and
    Xenon 2 will comply with the record-keeping and information filing
    requirements of Section 1.368-3 of the Treasury Regulations with respect to
    the Merger, and (B) Xenon 2 will file with its federal income tax return for
    the taxable year in which the Agreement is consummated (which tax return
    shall be timely filed) the information required by Treasury Regulations
    Section 1.351-3(b) and maintain such records as are required by Treasury
    Regulations Section 1.351-3(c) with respect to the Merger.

    6.12  TAX BENEFIT PAYMENTS.

    (a) If a Final Determination is made contrary to any of the positions
described in SECTION 6.11(b)(i), SECTION 6.11(b)(ii), or SECTION 6.11(b)(iii),
then (in addition to any other remedies which may be available to CNET but
without duplication thereof) Xenon 2 will pay to CNET for each Post-Closing Tax
Period an amount equal to the excess of (A) the liability for federal, state and
local Taxes to which Xenon 2, Xoom or any other Affiliates or any successor to
their assets or businesses (collectively, the "TAXPAYER") would have been
subject for all Post-Closing Tax Periods in each relevant jurisdiction had the
positions described in SECTION 6.11(b) been sustained (and had Xenon 2 not been
required to make any payments pursuant to this SECTION 6.12), over (B) the
Taxpayer's actual liability for such Taxes for such periods. Such payment will
be due (subject to a ten business-day grace period) when, as, and to the extent
the Taxpayer derives an actual benefit (in the form of any refund, reduction in
Tax liability, or otherwise) as the result of such excess. If any payment
required under this SECTION 6.12(a) for any Post-Closing Tax Period is not made
on or before the due date (without extensions) of the return of such period,
then such payment will be made together with interest at the rate per annum
determined from time to time under Section 6621(a)(2) of the Code compounded
daily for the period from such due date to the date on which the payment is
actually made.

                                     A-1-35
<PAGE>
    (b) In addition, Xenon 2 will pay to CNET, no later than ten business days
after each date on which the Taxpayer receives a refund of federal, state or
local Taxes for a Pre-Closing Tax Period, the excess of such refunds over such
refunds to which the Taxpayer would have been entitled had the positions
described in SECTION 6.11(b) been sustained (and had Xenon 2 not been required
to make any payments under this SECTION 6.12). If any payment required under
this SECTION 6.12(b) is not made on or before the date such payment is due, then
such payment will be made together with interest at the rate per annum
determined from time to time under Section 6621(a)(2) of the Code compounded
daily for the period from the date such payment was due to the date on which
such payment is actually made.

    (c) In the event of any adjustment to the Taxpayer's liability for federal,
state or local Taxes or entitlement to a refund, as a result of audit,
carryover, or otherwise, the amounts previously payable under this SECTION 6.12
will be appropriately adjusted and Xenon 2 or CNET, as the case may be, will pay
to the other the amount, required as a result of such adjustment, together with
interest at the rate per annum determined from time to time under Section
6621(a)(2) of the Code compounded daily for the period from the original payment
date affected by the adjustment to the date on which the payment is made. At the
time of any payment under this SECTION 6.12 (or at the request of CNET if Xenon
2 has determined that no payment is due), Xenon 2 will submit a schedule showing
in reasonable detail its calculation of the payment to be made (or the basis for
its determination that no payment is due). Any dispute concerning the
calculation of payments due under this SECTION 6.12 will be resolved by the
Independent Accountants.

    (d) Any payment to CNET under this SECTION 6.12 will be allocated between
principal and interest for purposes of Section 483, Section 1273, and any other
relevant provision of the Code by using as a discount rate the rate per annum
determined from time to time under Section 6621(a)(2) of the Code compounded
daily for the period from the date of Closing to the date on which the payment
is made. The portion of any such payment created as principal will be treated as
additional exchange consideration. Any payment to Xenon 2 under this SECTION
6.12 (other than interest) will be treated as a reduction of the exchange
consideration.

    (e) CNET will pay (i) any fees or other amounts due to the Independent
Accountants in respect of the resolution of any dispute pursuant to SECTION
6.12(c), and (ii) all reasonable costs (including the reasonable internal costs
of Xenon 2 or any Affiliate or successor thereto) incurred by Xenon 2 (or by
such Affiliate or successor) to comply with the provisions of this SECTION 6.12.

    6.13  AFFILIATES.  Not less than 45 days prior to the Effective Time, Xoom
shall deliver to Xenon 2 a letter identifying all persons who, in the opinion of
Xoom, may be deemed at the time this Agreement is submitted for adoption by the
stockholders of Xoom, "affiliates" of Xoom for purposes of Rule 145 under the
Securities Act, and such list shall be updated as necessary to reflect changes
from the date thereof. Xoom shall use its reasonable best efforts to cause each
person identified on such list to enter into and deliver to Xenon 2 not less
than 30 days prior to the Effective Time, a written agreement in connection with
the restrictions on affiliates under Rule 145 of the Securities Act (an
"AFFILIATE AGREEMENT").

    laws or regulations shall have expired or been terminated, except those for
    which failure to obtain such consents and approvals would not, individually

    of the Code or (ii) a "reorganization," within the meaning of Section 368(a)
    of the Code, and that each of Xenon 2, Xoom and Xenon 3 will be a "party to

    requested by counsel related to said opinion, which representations may be
    relied upon by the counsel providing such opinion, with such qualifications
    as are customary for such opinion.

provisions hereof, the Stockholder Approval):

        (a) Reserved.

        (b) by either CNET or Xoom by written notice to the other parties if the
    transactions contemplated by this Agreement have not been consummated by
    December 31, 1999, unless extended by written agreement of the parties
    hereto, PROVIDED that the party terminating this Agreement shall not be in
    material default or breach hereunder and PROVIDED, FURTHER, that the right
    to terminate this Agreement under this clause (b) shall not be available to
    any party whose failure to fulfill any obligation under this Agreement has
    been the cause of, or resulted in, the failure to consummate the
    transactions contemplated by this Agreement on or before such date;

        (c) by either CNET or Xoom if (i) any Governmental Authority, the
    consent or approval of which is required for the consummation of the
    transactions contemplated hereby, shall have determined not to grant its
    consent or approval and all appeals of such determination shall have been
    taken and have been unsuccessful or (ii) any court of competent jurisdiction
    in the United States shall have issued a final and unappealable permanent

        (d) by either CNET or Xoom if upon a vote at a duly held Stockholders

    purchase of 50% or more of the assets (based on the fair market value
    thereof) of Xoom and its Subsidiaries, taken as a whole, or of 50% or more
    of any class of equity securities of Xoom or any of its Subsidiaries or any
    tender offer or exchange offer (including by Xoom or its Subsidiaries) that
    if consummated would result in any person beneficially owning 50% or more of
    any class of equity securities of Xoom or any of its Subsidiaries, (B) a
    sale of all or substantially all of the assets of Xoom and its Subsidiaries
    or (C) a merger or consolidation of Xoom as a result of which the
    stockholders of Xoom immediately prior to such transaction would not
    beneficially own immediately after such transaction 50% or more of the
    resulting or surviving entity (or the parent thereof), in any such case with
    respect to which the Board of Directors of Xoom (i) determines in good faith
    and after consultation with a financial advisor of nationally recognized
    reputation to be on terms more favorable to the Xoom stockholders than the
    transactions contemplated by this Agreement and the NMC Merger Agreement and

    duties under applicable law.

    10.3  WAIVER.  No waiver by any of the parties hereto of any of the
provisions hereof shall be effective unless explicitly set forth in writing and
executed by the party so waiving. Except as provided in the preceding sentence,

waiver by the party taking such action of compliance with any representations,
warranties, covenants, or agreements contained herein, and in any documents
delivered or to be delivered pursuant to this Agreement and in connection with

and obligations hereunder may not be assigned, transferred, pledged, or
encumbered, in any manner, direct or indirect, contingent or otherwise, in whole

replace such illegal, void or unenforceable provision with a provision that
corresponds as closely as possible to the intentions of the parties as expressed

    effect and are valid and enforceable in accordance with their respective
    terms except for such failures to be in full force and effect and valid and
    enforceable that would not, individually or in the aggregate, have a
    Material Adverse Effect. No NBC Multimedia Business is in breach or default
    in the performance of any obligation thereunder and no event has occurred or
    has failed to occur

                                     A-2-12
<PAGE>
    whereby any of the other parties thereto have been or will be released

    SCHEDULE 4.1(K), none of the rights of NBC or its Subsidiaries to the NBC
    Multimedia Business Intellectual Property will be impaired in any way by the
    transactions provided for herein, and all of the rights of NBC and its
    Subsidiaries to the NBC Multimedia Business Intellectual Property will be
    fully enforceable by NMC after the Closing Date to the same extent as such
    rights would have been enforceable by NBC or its Subsidiaries before the
    Closing, without the consent or agreement of any other party other than any
    consents and agreements the failure of which to obtain, individually or in
    the aggregate, would not have a Material Adverse Effect. There have been no
    claims (whether private or governmental) against NBC or its Subsidiaries

    other right to use any of the registered NBC Multimedia Business
    Intellectual Property.

        (m)  CONDUCT OF BUSINESS IN COMPLIANCE WITH REGULATORY AND CONTRACTUAL
    REQUIREMENTS.  NBC and its Subsidiaries have complied with all applicable
    laws, ordinances, regulations or orders or other requirements of any
    Governmental Authority applicable to the NBC Multimedia Businesses,
    including, without limitation, all rules, regulations and administrative
    orders relating to anti-competitive practices, discrimination, employment,
    health and safety, except where the failure to be in such compliance would
    not have, either individually or in the aggregate, a Material Adverse
    Effect.

        (n)  ENVIRONMENTAL MATTERS.  Except as set forth on SCHEDULE 4.1(N) and
    except for matters that, individually or in the aggregate, would not have a
    Material Adverse Effect, (i) NBC and its Subsidiaries comply and have

    Businesses, and possess and comply with and have possessed and complied with
    all Environmental Permits for each NBC Multimedia Business; (ii) there are

    any Environmental Law; (iii) no judicial, administrative, or arbitral
    proceeding (including any notice of violation or alleged violation) under
    any Environmental Law to which any NBC or any of its Subsidiaries is, or to

    Multimedia Business nor is any NBC Multimedia Business the subject of any
    investigation in connection with any such proceeding or potential
    proceeding; (iv) there are no past, present, or anticipated future events,
    conditions, circumstances, practices, plans, or legal requirements that
    could be expected to prevent, or materially increase the burden on any NBC
    Multimedia Business of complying with applicable Environmental Laws or of
    obtaining, renewing, or complying with all Environmental Permits required
    under such laws; and (v) NBC has provided to the other parties true and
    complete copies of all Environmental Reports relating to the NBC Multimedia
    Businesses in the possession or control of NBC and its Subsidiaries.

        (o)  EMPLOYEE BENEFIT MATTERS.  (i) Neither NBC nor any of its
    Subsidiaries nor any Member of the Controlled Group of which it is a member
    has (A) engaged in, or is a successor or parent corporation to an entity
    that has engaged in, a transaction described in Sections 4069 or 4212(c) of
    ERISA or (B) incurred, or could reasonably be expected to incur, any
    liability under (I) Title IV of ERISA arising in connection with the
    termination of, or a complete or partial withdrawal from, any plan covered
    or previously covered by Title IV of ERISA or (II) Section 4971 of the Code
    that in either case could become a liability of Xenon 2 or any Subsidiary

    not now, nor will they after the passage of time be, subject to any lien
    imposed under Code Section 412(n) by reason of a failure of any of NBC or
    any Subsidiary or any Member of the Controlled Group of which it is a member
    to make timely installments or other payments required under Code Section
    412. SCHEDULE 6.7(A) sets forth (i) the names and salaries of each employee
    to whom Xenon 2 shall offer employment pursuant to SECTION 6.7 and (ii) any
    employment agreements between such employees and NBC or any of its
    Subsidiaries.

            (ii) Except as provided on SCHEDULE 4.1(O), no plan exists with

       them of any money or other property or accelerate or provide any other
       rights or benefits to them as a result of the transaction contemplated by
       this Agreement, whether or not such payment would constitute a parachute
       payment within the meaning of Code Section 280G.

        (p)  ABSENCE OF CERTAIN BUSINESS PRACTICES.  No officer, employee or
    agent of any NBC Multimedia Business, nor any other Person acting on behalf
    of any NBC Multimedia Business, has, directly or indirectly, within the past
    five years given or agreed to give any gift or similar benefit to

                                     A-2-14
<PAGE>
    any customer, supplier, governmental employee or other Person or entity who
    is or may be in a position to help or hinder any NBC Multimedia Business (or
    assist such NBC Multimedia Business in connection with any actual or
    proposed transaction) which (x) subjects any party or any of their
    respective Subsidiaries, to any damage or penalty in any civil, criminal or
    governmental litigation or proceeding, (y) if not given in the past, would
    have had a Material Adverse Effect or (z) if not continued in the future,
    would have a Material Adverse Effect or which might subject any party or any
    of their respective Subsidiaries, to suit or penalty in any private or
    governmental litigation or proceeding.

        (q)  ENTIRE BUSINESS.  Except as set forth in SCHEDULE 4.1(Q), the NBC
    Multimedia Assets and the Videoseeker Assets, including the License

    after the Effective Time in substantially the same manner as they are
    currently being conducted.

        (r)  TAX MATTERS.  (i) NBC and each of its Subsidiaries have timely
    filed (or have had timely filed on their behalf) or will timely file or
    cause to be timely filed, all Tax Returns required by applicable law to be
    filed by any of them prior to the Effective Time with respect to the NBC
    Multimedia Businesses or the assets, employees or businesses of or to be
    contributed by NBC or its Affiliates to CNBC.com. All such Tax Returns are
    or will be true, complete and correct in all material respects. There are no
    outstanding agreements or waivers extending the statutory period of
    limitation applicable to any of such Tax Returns and neither NBC nor any of
    its Subsidiaries has requested any extension of time within which to file
    any material Tax Return with respect to the NBC Multimedia Businesses or the
    assets, employees or businesses of or to be contributed by NBC or its
    Affiliates to CNBC.com, which return has not yet been filed. There is no
    pending claim by any authority of a jurisdiction where NBC or any of its
    Subsidiaries has not filed Tax Returns that NBC or such Subsidiary is or may
    have been subject to taxation by that jurisdiction with respect to the NBC
    Multimedia Businesses or the assets, employees or businesses of or to be
    contributed by NBC or its Affiliates to CNBC.com. All Taxes required to be
    withheld by NBC or its Affiliates with respect to the NBC Multimedia
    Businesses or CNBC.com or their activities, properties, employees or
    independent contractors have been withheld and paid over to the appropriate
    Tax Authority.

       their behalf), or where payment is not yet due, have established (or have
       had established on their behalf and for their sole benefit and recourse),
       or will establish or cause to be established on or before the Effective
       Time, an adequate accrual for the payment of, all Taxes due with respect
       to any period beginning prior to the Effective Time with respect to the
       NBC Multimedia Businesses or the assets, employees or businesses of or to
       be contributed by NBC or its Affiliates to CNBC.com. No deficiency or
       adjustment for any Taxes has been threatened, proposed, asserted or
       assessed against NBC or any of its Subsidiaries with respect to the NBC
       Multimedia Businesses or the assets, employees or businesses of or to be
       contributed by NBC or its Affiliates to CNBC.com. There are no liens for
       Taxes upon the assets of NBC or any of its Subsidiaries, except for liens
       for current Taxes not yet due, with respect to the NBC Multimedia
       Businesses or the assets, employees or businesses of or to be contributed
       by NBC or its Affiliates to CNBC.com.

           (iii) With respect to the NBC Multimedia Businesses or the assets,
       employees or businesses of or to be contributed by NBC or its Affiliates
       to CNBC, neither NBC nor any of its Subsidiaries is required to include
       in income any adjustment pursuant to Section 481(a) of the Code or any
       similar applicable provision by reason of a voluntary change in
       accounting method initiated by NBC or any of its Subsidiaries, and
       neither the Internal Revenue Service nor any taxing authority has
       proposed in writing any such adjustment or change in accounting method.
       Neither NBC nor any of its Subsidiaries has received a tax ruling or
       entered into a

                                     A-2-15
<PAGE>
       closing agreement with any taxing authority that would have a Material
       Adverse Effect upon the NBC Multimedia Businesses or the assets,
       employees or businesses of or to be contributed by NBC or its Affiliates
       to CNBC.

            (iv) With respect to the NBC Multimedia Business, neither NBC nor
       any of its Subsidiaries has made any payments, is obligated to make any
       payments, or is a party to any agreement, in each case, that could
       obligate it to make any payments that would not be deductible pursuant to
       Section 280G of the Code.

            (v) None of the NBC Multimedia Businesses or the business of
       CNBC.com has a "permanent establishment," as defined in any applicable
       Tax treaty or convention of the United States of America, or fixed place
       of business in any foreign country. NBC and its Affiliates are in
       compliance with the terms and conditions of any applicable tax
       exemptions, agreements or orders of any foreign government to which it
       may be subject or which it may have claimed with respect to the NBC
       Multimedia Businesses or the assets, employees or businesses of or to be
       contributed by NBC or its Affiliates to CNBC.com, and the transactions
       contemplated by this Agreement will not have any adverse effect on such
       compliance.

            (vi) CNBC.com shall initially be treated as a partnership for
       federal income tax purposes.

        (s)  ACCREDITED INVESTOR.  NBC is an "accredited investor" within the
    meaning of Rule 501 of Regulation D under the Securities Act. NBC (i) is
    acquiring the Class B Common Stock for investment for its own account and
    not with a view to, or for sale in connection with, any distribution
    thereof, in violation of the Securities Act; (ii) has had an opportunity to
    ask questions of the officers and directors of, and has had access to
    information concerning, Xenon 2 and its Subsidiaries; (iii) has knowledge,
    sophistication and experience in business and financial matters and risks of
    such investment; (iv) is able to bear the economic risk of such investment;
    and (v) is able to afford a complete loss of such investment.

        (t)  YEAR 2000 COMPLIANCE.  With respect to the NBC Multimedia
    Businesses, NBC has adopted and implemented a commercially reasonable plan
    to provide (x) that the change of the year from 1999 to the year 2000 will
    not have a Material Adverse Effect and (y) that the impacts of such change
    on the venders and customers of the NBC Multimedia Businesses will not have
    a Material Adverse Effect. In Neon's reasonable best estimate, no
    expenditures materially in excess of currently budgeted items previously
    disclosed to Xenon 2 will be required in order to cause the information and
    business systems of the NBC Multimedia Businesses to operate properly
    following the change of the year 1999 to the year 2000. NBC reasonably
    expects any material issues related to such change of the year will be
    resolved in accordance with the timetable set forth in such plan (and in any
    event on a timely basis in order to be resolved before the year 2000).
    Between May 9, 1999 and the Effective Time, NBC shall continue to use
    commercially reasonable efforts to implement such plan.

        (u)  NMC.  The authorized capital stock of NMC consists of 100 shares of
    common stock, par value $0.0001 per share, of which 100 shares have been
    issued and are outstanding and held by NBC Multimedia as of May 9, 1999. NMC
    has not conducted any activities other than in connection with its
    organization, the negotiation and execution of this Agreement and the
    consummation of the transactions contemplated hereby. Prior to the Closing
    Date, NMC's certificate of incorporation will be amended to provide for an
    authorized capital stock sufficient to permit NMC to issue shares of its
    common stock as described in SECTION 2.2(C).

        (v)  NO OTHER LIABILITIES.  Other than the NBC Multimedia Liabilities or
    Videoseeker Liabilities or as set forth on Schedule 1.1(e), there are no
    Liabilities of NBC or its Subsidiaries or GE Investments Sub that will be
    transferred or assigned to, or assumed by, NMC in connection with the
    transactions set forth in SECTION 2 or as to which NMC or Xenon 2 could be
    liable.

    operate its properties and to conduct its business as now conducted by it.
    SNAP is qualified to do business and is in good standing in all
    jurisdictions in which it conducts its business, except where the failure to
    do so would not, individually or in the aggregate, taken as a whole, have a
    Material Adverse Effect. SNAP has no Subsidiaries other than SNAP
    International LLC which has not commenced business operations and has no
    material assets or liabilities.

        (b)  AUTHORIZATION AND VALIDITY OF AGREEMENT.  The transfer of the
    interests in SNAP pursuant hereto have been duly authorized by all necessary
    action on the part of SNAP.

        (c)  GOVERNMENTAL APPROVALS; CONSENTS.  Except as described in SCHEDULE
    4.2(C), the execution, delivery and performance by NBC of this Agreement and

    NBC of the transactions contemplated hereby and thereby will not (i)
    conflict with or result in a breach of any provision of the SNAP LLC
    Agreement; (ii) require any consent, approval, authorization or permit of,
    or filing with, or notification to, any Governmental Authority; (iii)
    require the consent or approval of any Person (other than a Governmental

    authorizations and permits the failure of which to obtain and any
    violations, conflicts, breaches defaults and other matters set forth
    pursuant to clauses (ii), (iii) and (iv) above which, individually or in the
    aggregate, would not reasonably be expected to have a Material Adverse
    Effect.

        (d)  CERTAIN FEES.  Neither SNAP nor any of the officers, directors or
    employees, thereof has employed any broker or finder or incurred any other
    Liability for any brokerage fees, commissions or finders' fees in connection
    with the transactions contemplated hereby except that SNAP has employed of

    Agreement are consummated and otherwise will be paid by SNAP.

        (e)  EQUITY INTERESTS.  As of May 9, 1999, the outstanding equity
    interests in SNAP and the holders thereof are set forth on SCHEDULE 4.2(E)
    hereto. All outstanding SNAP Units are duly authorized, validly issued,
    fully paid and non-assessable and are not subject to any preemptive rights
    except as set forth in the SNAP LLC Agreement and have been issued in
    compliance with federal and state securities laws. There are no declared or
    accrued unpaid distributions with respect to any SNAP Units. The limited
    liability company interests of SNAP International LLC have been duly

    by SNAP free and clear of all Liens. Except for the capital stock of its
    Subsidiaries, SNAP does not own, directly or indirectly, more than 10% of
    the capital stock or other ownership interest in any Person and to the
    extent it owns less than 10% of the capital stock or other ownership
    interest in any Person, such interests in the aggregate do not constitute a
    material part of SNAP's assets. Except as set forth on SCHEDULE 4.2(E)
    hereto or as provided under the terms of this Agreement, no SNAP Units are
    reserved for issuance, and there are no contracts, agreements, commitments
    or arrangements obligating SNAP to (i) offer, sell, issue or grant any
    equity interests in, or any

    or any other securities that are convertible into or exchangeable for any
    equity interests in SNAP or (ii) to redeem, purchase or acquire, or offer to
    purchase or acquire, any outstanding equity interests in or any outstanding
    options, warrants or rights of any kind to acquire any equity interests in,

    exchangeable for any equity interests in SNAP. At the Effective Time, after
    giving effect to the transactions contemplated by the Xenon 2 Merger
    Agreement and this Agreement, Xenon 2 will own all of the outstanding SNAP
    Units, other than SNAP Units issued pursuant to the exercise of SNAP
    Options, free and clear of all Liens.

        (f)  FINANCIAL INFORMATION, LIABILITIES.  The unaudited balance sheet
    for SNAP as at December 31, 1998 (the "SNAP Balance Sheet") and the related
    unaudited income statement for the six months ending December 31, 1998,
    copies of which are attached hereto as SCHEDULE 4.2(F) present fairly in all
    material respects the financial condition and results of operations of SNAP
    as at December 31, 1998 and for the period then ended subject to normal
    year-end audit adjustments and financial statement footnote disclosure.
    Except as set forth on SCHEDULE 4.2(G), except as and to the extent
    disclosed in the SNAP Balance Sheet, and except for liabilities incurred in
    connection with the transactions contemplated by this Agreement and the
    Implementing Agreements, there are no liabilities, whether absolute,
    accrued, contingent or otherwise, of SNAP, that would be required to be
    reflected on, or reserved against, in such consolidated balance sheet of
    SNAP, except for (x) liabilities which, singly or in the aggregate, would
    not have a Material Adverse Effect and (y) liabilities incurred subsequent
    to the date of such balance sheet by SNAP in the ordinary course of business
    consistent with past practice.

        (g)  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as disclosed on
    SCHEDULE 4.2(G) since December 31, 1998, SNAP has conducted its business in
    all material respects only in the ordinary course consistent with past
    practice and there has not been (i) any material adverse change in the
    assets, liabilities, business, results of operations or financial condition
    of SNAP, or (ii) except in the ordinary course of business consistent with
    past practice and except for such matters that would not reasonably be
    expected to have a Material Adverse Effect, any damage, destruction, loss,
    conversion, condemnation or taking by eminent domain related to any of its
    material assets. In addition, except as disclosed on SCHEDULE 4.2(G), from
    December 31, 1998 to May 9, 1999, SNAP has not (A) acquired or disposed of
    any material assets or entered into any agreement or other arrangement for
    any such acquisition or disposition or (B) relinquished, forgiven or
    canceled any material debts or claims.

        (h)  TITLE TO PROPERTIES; ABSENCE OF LIENS.  Except as disclosed on
    SCHEDULE 4.2(H), SNAP has good title to (or, in the case of real estate or
    equipment leases, a valid lease to) all of its properties, assets and other
    rights, free and clear of all Liens except for Permitted Liens and such
    assets will enable Xenon 2 to conduct the business of SNAP after the
    Effective Time in substantially the same manner as it is currently being
    conducted.

        (i)  PROPERTIES, CONTRACTS, PERMITS AND OTHER DATA.  Except as specified
    in SCHEDULE 4.2(I) hereto, all rights, licenses, leases, registrations,
    applications, contracts, commitments and other agreements of SNAP or by
    which SNAP is bound are in full force and effect and are valid and
    enforceable in accordance with their respective terms except for such
    failures to be in full force and effect and valid and enforceable that would
    not, individually or in the aggregate, have a Material Adverse Effect. SNAP
    is not in breach or default in the performance of any obligation thereunder
    and no event has occurred or has failed to occur whereby any of the other
    parties thereto have been or will be released therefrom or will be entitled
    to refuse to perform thereunder, the enforcement of which would have, either
    individually or in the aggregate, a Material Adverse Effect. SNAP has
    provided to Xoom complete and accurate copies of SNAP's current annual
    budget and operating plan (the "SNAP Budget").

                                     A-2-18
<PAGE>
        (j)  LEGAL PROCEEDINGS.  Except as described in SCHEDULE 4.2(J), there
    is no litigation, proceeding or governmental investigation to which SNAP is
    a party pending or, to the best Knowledge of SNAP, threatened against it or
    its assets which, either individually or in the aggregate, would reasonably
    be expected to result in a Material Adverse Effect or which, as of May 9,
    1999, seeks to restrain or enjoin the consummation of any of the
    transactions contemplated hereby. SNAP is not a party to nor are its assets
    subject to any judgment, writ, decree, injunction or order entered by any
    court or governmental authority (domestic or foreign) that, individually or
    in the aggregate, would reasonably be expected to have a Material Adverse
    Effect.

        (k)  LABOR CONTROVERSIES.  Except as set forth on SCHEDULE 4.2(K), (i)
    there have been no labor strikes, slow-downs, work stoppages, lock-outs or
    other material labor controversies or disputes during the past two years,
    nor is any such strike, slow-down, work stoppage or other material labor
    controversy or dispute pending or, to the best Knowledge of NBC, threatened
    with respect to the current or former employees of SNAP, (ii) SNAP is not a
    party to any labor contract, collective bargaining agreement, contract,

    employees represented by any labor union or organization and (iii) SNAP has
    not closed any facility, effectuated any layoffs of employees or implemented
    any early retirement, separation or window program within the past two years
    nor planned or announced any such action or program for the future.

        (l)  INTELLECTUAL PROPERTY.  SNAP owns or is licensed or otherwise has
    the right to use, all Intellectual Property currently used in its business
    (the "SNAP Intellectual Property"), except as would not, individually or in
    the aggregate, have a Material Adverse Effect. SNAP has not infringed upon
    or is in conflict with the Intellectual Property of any third party nor has
    SNAP received any written notice of any claim that it has infringed upon or
    is in conflict with any Intellectual Property of any third party, except as
    would not, individually or in the aggregate, have a Material Adverse Effect.
    Except as set forth on SCHEDULE 4.2(L), none of the rights of SNAP to the
    SNAP Intellectual Property will be impaired in any way by the transactions
    provided for herein, and all of the rights of SNAP to the SNAP Intellectual
    Property will be fully enforceable by SNAP after the Closing Date to the
    same extent as such rights would have been enforceable by SNAP before the
    Closing, without the consent or agreement of any other party other than any
    consents and agreements the failure of which to obtain, individually or in
    the aggregate, would not have a Material Adverse Effect. There have been no
    claims (whether private or governmental) against SNAP asserting the
    invalidity or unenforceability of its ownership, license or other right to
    use any of the registered SNAP Intellectual Property.

        (m)  GOVERNMENT LICENSES, PERMITS, ETC.  Except as set forth on SCHEDULE
    4.2(M), SNAP has all licenses, permits, consents, approvals, authorizations,
    qualifications and orders of Governmental Authorities required for the
    conduct of its business as presently conducted, except where failure would
    not, individually or in the aggregate, have a Material Adverse Effect.

        (n)  CONDUCT OF BUSINESS IN COMPLIANCE WITH REGULATORY AND CONTRACTUAL
    REQUIREMENTS.  SNAP has complied with all applicable laws, ordinances,
    regulations or orders or other requirements of any Governmental Authority
    including, without limitation, all rules, regulations and administrative
    orders relating to anti-competitive practices, discrimination, employment,
    health and safety, except where the failure to be in such compliance would
    not have, either individually or in the aggregate, a Material Adverse
    Effect.

        (o)  ENVIRONMENTAL MATTERS.  Except as set forth on SCHEDULE 4.2(O) and
    except for matters that, individually or in the aggregate, would not have a
    Material Adverse Effect, (i) SNAP complies and has complied with all
    applicable Environmental Laws, and possesses and complies with and has
    possessed and complied with all Environmental Permits; (ii) there are and
    have been

                                     A-2-19

    owned or leased by SNAP that could give rise to any liability under any
    Environmental Law or result in costs arising out of any Environmental Law;
    (iii) no judicial, administrative, or arbitral proceeding (including any
    notice of violation or alleged violation) under any Environmental Law to
    which SNAP is, or to the Knowledge of SNAP will be, named as a party is
    pending or, to the Knowledge of SNAP, threatened, nor is SNAP the subject of
    any investigation in connection with any such proceeding or potential
    proceeding; (iv) there are no past, present, or anticipated future events,
    conditions, circumstances, practices, plans, or legal requirements that
    could be expected to prevent, or materially increase the burden on SNAP of
    complying with applicable Environmental Laws or of obtaining, renewing, or
    complying with all Environmental Permits required under such laws; and (v)
    SNAP has provided to the other parties true and complete copies of all
    Environmental Reports relating to it in the possession or control of such
    party.

        (p)  EMPLOYEE BENEFIT MATTERS.  (i) SCHEDULE 4.2(P) contains a true and
    complete list of each "employee benefit plan" (within the meaning of section
    3(3) of ERISA, and all stock purchase, stock option, severance, employment,
    change-in-control, fringe benefit, collective bargaining, bonus, incentive,
    deferred compensation and other employee benefit plans, agreements,
    programs, policies or other arrangements, whether or not subject to ERISA
    (including any funding mechanism therefor now in effect or required in the
    future as a result of the transaction contemplated by this Agreement or
    otherwise), whether formal or informal, oral or written, legally binding or
    not, under which any employee or former employee of SNAP or its Subsidiaries
    has any present or future right to benefits and under which SNAP or its
    Subsidiaries has any present or future liability. All such plans,
    agreements, programs, policies and arrangements shall be collectively
    referred to as the "SNAP PLANS".

            (ii) With respect to each SNAP Plan which is maintained solely by
       SNAP (the "Portal Level Plans"), SNAP has made available to NBC a
       current, accurate and complete copy (or, to the extent no such copy
       exists, an accurate description) thereof and, to the extent applicable:
       (A) any related trust agreement or other funding instrument; (B) the most
       recent determination letter, if applicable; (C) any summary plan
       description and other written communications (or a description of any
       oral communications) by SNAP or its Subsidiaries to their employees
       concerning the extent of the benefits provided under a SNAP Plan; and (D)
       for the most recent two years (I) the Form 5500 and attached schedules
       and (II) audited financial statements.

           (iii) (A) Each SNAP Plan has been established and administered in
       accordance with its terms, and in compliance with the applicable
       provisions of ERISA, the Code and other applicable laws, rules and
       regulations; (B) each SNAP Plan which is intended to be qualified within
       the meaning of Code section 401(a) is so qualified and has received a
       favorable determination letter as to its qualification (or is established
       using a prototype plan form which has received such a letter), and
       nothing has occurred, whether by action or failure to act, that could
       reasonably be expected to cause the loss of such qualification; (C) for
       each SNAP Plan with respect to which a Form 5500 has been filed, no
       material change has occurred with respect to the matters covered by the
       most recent Form since the date thereof; (D) no non-exempt "prohibited
       transaction" (as such term is defined in ERISA section 406 and Code
       section 4975) with respect to any SNAP Plan; and (E) no SNAP Plan
       provides retiree welfare benefits and neither SNAP nor its Subsidiaries
       have any obligations to provide any retiree welfare benefits except as
       provided under Section 4980B of the Code.

            (iv) No SNAP Plan is subject to Title IV of ERISA (including a
       multiemployer plan within the meaning of Section 3(37) of ERISA), no SNAP
       Plan is a multiple employer plan; and no SNAP Plan is subject to the
       minimum funding requirements of ERISA Section 302 or Code Section 412.

                                     A-2-20
<PAGE>
            (v) Neither SNAP nor any of its Subsidiaries nor any member of the
       Controlled group of which it is a member has (A) engaged in, or is a
       successor or parent corporation to an entity that has engaged in, a
       transaction described in Sections 4069 or 4212(c) of ERISA or (B)
       incurred, or could reasonably be expected to incur, any liability under
       (I) Title IV of ERISA arising in connection with the termination of, or a
       complete or partial withdrawal from, any plan covered or previously
       covered by Title IV of ERISA or (II) Section 4971 of the Code that in
       either case could become a liability of the SNAP or any Subsidiary or NMC
       after the Closing Date. The assets of SNAP and all of its Subsidiaries
       are not now, nor will they after the passage of time be, subject to any
       lien imposed under Code Section 412(n) by reason of a failure of any of
       the SNAP or any Subsidiary or any member of the Controlled Group of which
       it is a member to make timely installments or other payments required
       under Code Section 412.

            (vi) With respect to any SNAP Plan, (A) no actions, suits or claims
       (other than routine claims for benefits in the ordinary course) are
       pending or, to the Knowledge of SNAP or its Subsidiaries, threatened and
       (B) no facts or circumstances exist that could reasonably be expected to
       give rise to any such actions, suits or claims.

           (vii) Except as provided on SCHEDULE 4.2(P), no SNAP Plan exists that
       could result in the payment to any present or former employee of SNAP or
       its Subsidiaries of any money or other property or accelerate or provide
       any other rights or benefits to any present or former employee of SNAP or
       its Subsidiaries as a result of the transaction contemplated by this
       Agreement, whether or not such payment would constitute a parachute
       payment within the meaning of Code Section 280G.

        (q)  ABSENCE OF CERTAIN BUSINESS PRACTICES.  Neither SNAP, nor any
    officer, employee or agent of SNAP, nor any other Person acting on behalf of
    SNAP, has, directly or indirectly, within the past five years given or
    agreed to give any gift or similar benefit to any customer, supplier,
    governmental employee or other Person or entity who is or may be in a
    position to help or hinder SNAP (or assist SNAP in connection with any
    actual or proposed transaction) which (x) subjects any party or NMC or any
    of their respective Affiliates, to any damage or penalty in any civil,
    criminal or governmental litigation or proceeding, (y) if not given in the
    past, could have had a Material Adverse Effect or (z) if not continued in
    the future, could have a Material Adverse Effect or which might subject any
    party or NMC or any of their respective Affiliates to suit or penalty in any
    private or governmental litigation or proceeding.

        (r)  TAX MATTERS.  Except as set forth on SCHEDULE 4.2(R),(i) SNAP and
    its Subsidiaries have timely filed (or have had timely filed on their
    behalf) or will timely file or cause to be timely filed, all Tax Returns
    required by applicable law to be filed by SNAP and its Subsidiaries prior to
    the Effective Time. All such Tax Returns are or will be true, complete and
    correct in all material respects. There are no outstanding agreements or
    waivers extending the statutory period of limitation applicable to any of
    such Tax Returns and SNAP and its Subsidiaries has not requested any
    extension of time within which to file any material Tax Return, which return
    has not yet been filed. There is no pending claim by any Tax Authority of a
    jurisdiction where SNAP or any of its Subsidiaries have not filed Tax
    Returns that SNAP are any of its Subsidiaries are or may have been subject
    to taxation by that jurisdiction. All Taxes required to be withheld by SNAP
    or its Affiliates with respect to their activities, properties, employees or
    independent contractors have been withheld and paid over to the appropriate
    Tax Authority.

            (ii) SNAP and its Subsidiaries have paid (or have had paid on their
       behalf), or where payment is not yet due, have established (or have had
       established on their behalf and for their sole benefit and recourse), or
       will establish or cause to be established on or before the Effective
       Time, an adequate accrual for the payment of, all Taxes due with respect
       to any

                                     A-2-21
<PAGE>
       period beginning prior to the Effective Time. No deficiency or adjustment
       for any Taxes has been threatened, proposed, asserted or assessed against
       SNAP or its Subsidiaries. There are no liens for Taxes upon the assets of
       SNAP or its Subsidiaries, except for liens for current Taxes not yet due.

           (iii) SNAP and its Subsidiaries are not required to include in income
       any adjustment pursuant to Section 481(a) of the Code or any similar
       applicable provision by reason of a voluntary change in accounting method
       initiated by SNAP or its Subsidiaries, and neither the Internal Revenue
       Service nor any taxing authority has proposed in writing any such
       adjustment or change in accounting method. SNAP and its Subsidiaries have
       not received a tax ruling or entered into a closing agreement with any
       taxing authority that would have a Material Adverse Effect on SNAP or its
       Subsidiaries.

            (iv) SNAP and its Subsidiaries have not made any payments, are not
       obligated to make any payments, and are not a party to any agreement that
       could obligate it to make any payments that would not be deductible
       pursuant to Section 280G of the Code.

            (v) SNAP has been and currently is taxable as a partnership for
       federal income tax purposes and in all jurisdictions in which it is
       subject to Taxes or files Tax Returns. Each of SNAP's Subsidiaries has
       been and currently is (A) wholly owned by SNAP and (B) an entity
       disregarded from its owner pursuant to Section 301.7701-2 of the Treasury
       Regulations. Neither SNAP nor any Subsidiary is a party to any safe
       harbor lease within the meaning of Section 168(f)(8) of the Code, as in
       effect prior to amendment by the Tax Equity and Fiscal Responsibility Act
       of 1982. SNAP and its Subsidiaries are not a party to any joint venture,
       partnership, or other agreement, contract, or arrangement (either in
       writing or verbally, formally or informally) which could be treated as
       partnership for federal income tax purposes.

            (vi) Neither SNAP nor any of its Subsidiaries has a "permanent
       establishment," as defined in any applicable Tax treaty or convention of
       the United States of America, or fixed place of business in any foreign
       country. SNAP and its Subsidiaries are in compliance with the terms and
       conditions of any applicable tax exemptions, agreements or orders of any
       foreign government to which it may be subject or which it may have
       claimed, and the transactions contemplated by this Agreement will not
       have any adverse effect on such compliance.

           (vii) Neither SNAP nor any of its Subsidiaries is or has been bound
       by any tax sharing or tax allocation agreement, and it has no contractual
       obligation to indemnify any other person with respect to Taxes.

        (s)  YEAR 2000 COMPLIANCE.  SNAP has adopted and implemented a
    commercially reasonable plan to provide (x) that the change of the year from
    1999 to the year 2000 will not have a Material Adverse Effect and (y) that
    the impacts of such change on the venders and customers of SNAP will not
    have a Material Adverse Effect. In SNAP's reasonable best estimate, no
    expenditures materially in excess of currently budgeted items previously
    disclosed to Xenon 2 will be required in order to cause the information and
    business systems of SNAP to operate properly following the change of the
    year 1999 to the year 2000. SNAP reasonably expects any material issues
    related to such change of the year will be resolved in accordance with the
    timetable set forth in such plan (and in any event on a timely basis in
    order to be resolved before the year 2000). Between the date of this
    Agreement and the Effective Time, SNAP shall continue to use commercially
    reasonable efforts to implement such plan.

        (t)  OPTIONS.  Except for the SNAP 1998 LLC Option Plan, SNAP has never
    adopted or maintained any option plan or other plan providing for equity
    compensation of any Person. As of May 9, 1999, SNAP has reserved 1,604,938
    units for issuance pursuant to the SNAP 1998 LLC Option Plan ("SNAP
    Options"), of which 1,432,970 have been issued as of May 9, 1999, all of

                                     A-2-22
<PAGE>
    which units remain subject to SNAP Options unexercised as of May 9, 1999.
    Except as set forth in SCHEDULE 4.2(T), none of the SNAP Options will be
    accelerated in any way by the transactions contemplated by this Agreement.
    SNAP has made available to NBC accurate and complete copies of all option
    plans pursuant to which SNAP has granted options and the applicable vesting
    schedule for each such option. All units subject to issuance as aforesaid,
    upon issuance on the terms and conditions specified in the instruments
    pursuant to which they are issuable, would be duly authorized, validly
    issued, fully paid and non-assessable. Except as set forth in SCHEDULE
    4.2(T), there are no commitments or agreements of any character to which
    SNAP is bound obligating SNAP to accelerate the vesting of any SNAP Options
    as a result of this Agreement. SCHEDULE 4.2(E) lists each outstanding SNAP
    Option and identifies with respect to each such SNAP Option; its exercise
    price; its grant date; its vesting schedule; and what portion of such SNAP
    Option remains outstanding as of May 9, 1999. NBC shall prepare and deliver
    to Xenon 2 and Xoom an updated version of SCHEDULE 4.2(E) prior to the
    Effective Time as of a date no earlier than 5 days prior to the Effective
    Time.

    a Material Adverse Effect on Xoom (other than claims, liabilities or
    obligations contemplated by this Agreement or expressly permitted to be

    Subsidiaries own or are licensed or otherwise have the right to use, all
    Intellectual Property currently used by Xoom, Xenon 2 and each of their
    respective Subsidiaries (the "Xoom Intellectual Property"), except as would

    Subsidiaries before the Closing, without the consent or agreement of any
    other party other than any consents and agreements the failure of which to
    obtain, individually or in the aggregate, would not have a Material Adverse
    Effect. There have been no claims (whether private or governmental) against

        (q)  EMPLOYEE BENEFIT MATTERS.  (i) SCHEDULE 4.3(Q)(I) contains a true
    and complete list of each "employee benefit plan" (within the meaning of
    section 3(3) of ERISA), and all stock purchase, stock option, severance,
    employment, change-in-control, fringe benefit, collective bargaining, bonus,
    incentive, deferred compensation and other employee benefit plans,
    agreements, programs, policies or other arrangements, whether or not subject
    to ERISA (including any funding mechanism therefor now in effect or required
    in the future as a result of the transaction contemplated by this Agreement
    or otherwise), whether formal or informal, oral or written, legally binding
    or not, under which any employee or former employee of Xoom, Xenon 2 or
    their respective Subsidiaries has any present or future right to benefits
    and under which Xoom, Xenon 2 or their respective Subsidiaries has any
    present or future liability. All such plans, agreements, programs, policies
    and arrangements shall be collectively referred to as the "XOOM PLANS".

            (ii) With respect to each Xoom Plan, Xoom, Xenon 2 and their
       respective Subsidiaries have made available to NBC a current, accurate
       and complete copy (or, to the extent no such copy exists, an accurate
       description) thereof and, to the extent applicable: (A) any related trust
       agreement or other funding instrument; (B) the most recent determination
       letter, if applicable; (C) any summary plan description and other written
       communications (or a description of any oral communications) by Xoom,
       Xenon 2 or their respective Subsidiaries to their employees concerning
       the extent of the benefits provided under a Xoom Plan; and (D) for the
       most recent two years (I) the Form 5500 and attached schedules and (II)
       audited financial statements.

           (iii) (A) Except as set forth on SCHEDULE 4.3(Q)(III), each Xoom Plan
       has been established and administered in accordance with its terms, and
       in compliance with the applicable provisions of ERISA, the Code and other
       applicable laws, rules and regulations; (B) each Xoom Plan which is
       intended to be qualified within the meaning of Code section 401(a) is so
       qualified and has received a favorable determination letter as to its
       qualification (or established using a prototype plan form which has
       received such a letter), and nothing has occurred, whether by action or
       failure to act, that could reasonably be expected to cause the loss of
       such qualification; (C) for each Xoom Plan with respect to which a Form
       5500 has

                                     A-2-28
<PAGE>
       been filed, no material change has occurred with respect to the matters
       covered by the most recent Form since the date thereof; (D) no nonexempt
       "prohibited transaction" (as such term is defined in ERISA section 406
       and Code section 4975) with respect to Xoom Plans; and (E) no Xoom Plan
       provides retiree welfare benefits and none of Xoom, Xenon 2 or any of
       their respective Subsidiaries have any obligations to provide any retiree
       welfare benefits except as provided under Section 4980B of the Code.

            (iv) No Xoom Plan is subject to Title IV of ERISA (including a
       multiemployer plan within the meaning of Section 3(37) of ERISA), no Xoom
       Plan is a multiple employer plan; and no Xoom Plan is subject to the
       minimum funding requirements of ERISA Section 302 or Code Section 412.

            (v) None of Xoom, Xenon 2 or any of their respective Subsidiaries
       nor any Member of the Controlled Group of which it is a member has (A)
       engaged in, or is a successor or parent corporation to an entity that has
       engaged in, a transaction described in Sections 4069 or 4212(c) of ERISA
       or (B) incurred, or could reasonably be expected to incur, any liability
       under (I) Title IV of ERISA arising in connection with the termination
       of, or a complete or partial withdrawal from, any plan covered or
       previously covered by Title IV of ERISA or (II) Section 4971 of the Code
       that in either case could become a liability of Xenon 2, Xoom or NMC or
       any of their respective Subsidiaries after the Closing Date. The assets
       of Xoom, Xenon 2 and all of their respective Subsidiaries are not now,
       nor will they after the passage of time be, subject to any lien imposed
       under Code Section 412(n) by reason of a failure of any of any Subsidiary
       or any Member of the Controlled Group of which it is a member to make
       timely installments or other payments required under Code Section 412.

            (vi) With respect to any Xoom Plan, (A) no actions, suits or claims
       (other than routine claims for benefits in the ordinary course) are
       pending or, to the Knowledge of Xoom, Xenon 2 or their respective
       Subsidiaries, threatened and (B) no facts or circumstances exist that
       could reasonably be expected to give rise to any such actions, suits or
       claims.

           (vii) Except as provided on SCHEDULE 4.3(Q)(VII), no Xoom Plan exists
       that could result in the payment to any present or former employee of
       Xoom, Xenon 2 or their respective Subsidiaries of any money or other
       property or accelerate or provide any other rights or benefits to any
       present or former employee of Xoom, Xenon 2 or their respective
       Subsidiaries as a result of the transaction contemplated by this
       Agreement, whether or not such payment would constitute a parachute
       payment within the meaning of Code Section 280G.

        (r)  ABSENCE OF CERTAIN BUSINESS PRACTICES.  None of Xoom, Xenon 2 or
    any of their respective Subsidiaries, nor any officer, employee or agent
    thereof, nor any other Person acting on behalf of such Persons, has,
    directly or indirectly, within the past five years given or agreed to give
    any gift or similar benefit to any customer, supplier, governmental employee
    or other Person or entity who is or may be in a position to help or hinder
    Xoom, Xenon 2 or their respective Subsidiaries (or assist Xoom, Xenon 2 or
    their respective Subsidiaries in connection with any actual or proposed
    transaction) which (x) subjects any party or Xenon 2 or any of their
    respective Subsidiaries, to any damage or penalty in any civil, criminal or
    governmental litigation or proceeding, (y) if not given in the past, could
    have had a Material Adverse Effect or (z) if not continued in the future,
    could have a Material Adverse Effect or which might subject any party or
    Xenon 2 or any of their respective Subsidiaries to suit or penalty in any
    private or governmental litigation or proceeding.

        (s)  TAX MATTERS.  Except as set forth on SCHEDULE 4.3(S),(i) Xoom,
    Xenon 2 and each of their respective Subsidiaries have timely filed (or have
    had timely filed on their behalf) or will timely file or cause to be timely
    filed, all Tax Returns required by applicable law to be filed by any of them
    prior to the Effective Time. All such Tax Returns are or will be true,
    complete and correct in all

                                     A-2-29
<PAGE>
    material respects. There are no outstanding agreements or waivers extending
    the statutory period of limitation applicable to any of such Tax Returns and
    none of Xoom, Xenon 2 nor any of their respective Subsidiaries has requested
    any extension of time within which to file any material Tax Return, which
    return has not yet been filed. There is no pending claim by any Tax
    Authority of a jurisdiction where Xoom, Xenon 2 or any of their respective
    Subsidiaries has not filed Tax Returns that Xoom, Xenon 2 or such Subsidiary
    is or may have been subject to taxation by that jurisdiction. All Taxes
    required to be withheld by Xoom, Xenon 2 or their respective Affiliates with
    respect to their activities, properties, employees or independent
    contractors have been withheld and paid over to the appropriate Tax
    Authority.

            (ii) Xoom, Xenon 2 and each of their respective Subsidiaries have
       paid (or have had paid on their behalf), or where payment is not yet due,
       have established (or have had established on their behalf and for their
       sole benefit and recourse), or will establish or cause to be established
       on or before the Effective Time, an adequate accrual for the payment of,
       all Taxes due with respect to any period beginning prior to the Effective
       Time. No deficiency or adjustment for any Taxes has been threatened,
       proposed, asserted or assessed against Xoom, Xenon 2 or any of their
       respective Subsidiaries. There are no liens for Taxes upon the assets of
       Xoom, Xenon 2 or any of their respective Subsidiaries, except for liens
       for current Taxes not yet due.

           (iii) None of Xoom, Xenon 2 or any of their respective Subsidiaries
       is required to include in income any adjustment pursuant to Section
       481(a) of the Code or any similar applicable provision by reason of a
       voluntary change in accounting method initiated by Xoom, Xenon 2 or any
       of their respective Subsidiaries, and neither the Internal Revenue
       Service nor any taxing authority has proposed in writing any such
       adjustment or change in accounting method. None of Xoom, Xenon 2 or any
       of their respective Subsidiaries has received a tax ruling or entered
       into a closing agreement with any taxing authority that would have a
       continuing Material Adverse Effect upon Xoom, Xenon 2 or any of their
       respective Subsidiaries.

            (iv) None of Xoom, Xenon 2 or any of their respective Subsidiaries
       has made any payments, is obligated to make any payments, or is a party
       to any agreement that could obligate it to make any payments that would
       not be deductible pursuant to Section 280G of the Code.

            (v) None of Xoom, Xenon 2 or any of their respective Subsidiaries
       has a permanent establishment, as defined in any applicable Tax treaty or
       convention of the United States of America, or fixed place of business in
       any foreign country. Xoom, Xenon 2 and their respective Affiliates are in
       compliance with the terms and conditions of any applicable tax
       exemptions, agreements or orders of any foreign government to which it
       may be subject or which it may have claimed, and the transactions
       contemplated by this Agreement will not have any adverse effect on such
       compliance.

            (vi) Neither Xoom nor any Subsidiary is a party to any safe harbor
       lease within the meaning of Section 168(f)(8) of the Code, as in effect
       prior to amendment by the Tax Equity and Fiscal Responsibility Act of
       1982. Xoom and its Subsidiaries are not a party to any joint venture,
       partnership, or other agreement, contract, or arrangement (either in
       writing or verbally, formally or informally) which could be treated as
       partnership for federal income tax purposes.

           (vii) Neither Xoom nor any of its Subsidiaries is or has been bound
       by any tax sharing or tax allocation agreement, and it has no contractual
       obligation to indemnify any other person with respect to Taxes.

<PAGE>
        (t)  SECTION 203.  The Boards of Directors of Xoom, Xenon 2 and each of
    their respective Subsidiaries has taken appropriate action so that the
    provisions of Section 203 of the DGCL restricting business combinations with
    interested stockholders (each as defined in such Section 203) will not,
    prior to the termination of this Agreement pursuant to Article IX hereof,
    apply to NBC or NMC or any of their Affiliates with respect to this
    Agreement, the Xenon 2 Merger Agreement, the Option Agreement, the Voting
    Agreement, any of the Implementing Agreements or any of the transactions
    contemplated hereby or thereby.

        (u)  YEAR 2000 COMPLIANCE.  Except as set forth on SCHEDULE 4.3(V),
    Xoom, Xenon 2 and each of their respective Subsidiaries has adopted and
    implemented a commercially reasonable plan to provide (x) that the change of
    the year from 1999 to the year 2000 will not have a Material Adverse Effect
    and (y) that the impacts of such change on the venders and customers of
    Xoom, Xenon 2 and each of their respective Subsidiaries will not have a
    Material Adverse Effect. In the reasonable best estimate of Xoom, Xenon 2
    and each of their respective Subsidiaries, no expenditures materially in
    excess of currently budgeted items previously disclosed to Xenon 2 will be
    required in order to cause the information and business systems of Xoom,
    Xenon 2 and each of their respective Subsidiaries to operate properly
    following the change of the year 1999 to the year 2000. Xoom, Xenon 2 and
    each of their respective Subsidiaries reasonably expects any material issues
    related to such change of the year will be resolved in accordance with the
    timetable set forth in such plan (and in any event on a timely basis in
    order to be resolved before the year 2000). Between May 9, 1999 and the
    Effective Time, Xoom, Xenon 2 and each of their respective Subsidiaries
    shall continue to use commercially reasonable efforts to implement such
    plan.

        (v)  NO BUSINESS ACTIVITIES.  Neither Xenon 2 nor Xenon 3 has conducted
    any activities other than in connection with their organization, the
    negotiation and execution of this Agreement and the NMC Merger Agreement and
    the consummation of the transactions contemplated hereby and thereby.

law, the parties agree not to disclose to any third party (other than their
respective professional advisors) any portion of the information so provided
which constitutes confidential information (i.e., information that is not
otherwise publicly available). The confidential information shall not, without
the other parties' prior written consent, be disclosed to third parties. The
parties will disclose the information internally only to persons who require
knowledge thereof for the purposes of the transactions contemplated hereby.

    5.5  NO SOLICITATION.  (a) From and after May 9, 1999 until the earlier of
the Effective Time or the termination of this Agreement in accordance with its
terms, Xoom shall not, nor shall it permit any of its Subsidiaries to, nor shall
it authorize or permit any officer, director or employee of, or any investment
banker, attorney or other advisor or representative of, Xoom or any of its
Subsidiaries to, directly or indirectly, (i) take any action to solicit,
initiate, encourage or knowingly facilitate any Material Transaction Proposal
(as defined below) or the submission of a Material Transaction Proposal or (ii)
enter into or participate in any discussions or negotiations regarding, or
furnish to any person any information with respect to, a Material Transaction
Proposal; PROVIDED that, prior to obtaining the affirmative vote of the holders
of a majority of the outstanding shares of common stock of Xoom to adopt the
Xenon 2 Merger Agreement (the "Xoom Stockholder Approval" and, together with the

                                     A-2-36
<PAGE>
Xenon 2 Stockholder Approval, the "Stockholder Approvals"), in response to an
unsolicited BONA FIDE Takeover Proposal, Xoom may, to the extent that the Board
of Directors of Xoom determines in good faith based on the advice of outside
legal counsel that such action is required to comply with their fiduciary duties
under applicable law, (A) furnish information with respect to Xoom and its
Subsidiaries to the person making such Takeover Proposal and its representatives
and discuss such information with such person and its representatives and (B)
participate in negotiations regarding such Takeover Proposal. Xoom will promptly
notify NBC of receipt of any request for information or any Material Transaction
Proposal, the material terms and conditions of such request or Material
Transaction Proposal and the identity of the person making any such request or
Material Transaction Proposal, and will keep NBC fully informed on a current
basis of the status and details of any such request or Material Transaction
Proposal, PROVIDED that, prior to providing any information to any Person or
participating in negotiations with any Person, Xoom shall have received an
executed confidentiality agreement. Xoom will immediately cease and cause to be
terminated any existing activities, discussions and negotiations conducted
heretofore with respect to any Material Transaction Proposal.

        (b) From and after May 9, 1999 until the earlier of the Effective Time
    or the termination of this Agreement in accordance with its terms, the Board
    of Directors of Xoom shall not (i) approve or recommend or propose publicly
    to approve or recommend any Material Transaction Proposal, (ii) cause or
    agree to cause Xoom or any of its Subsidiaries to enter into any agreement
    (including, without limitation, any letter of intent or agreement in
    principle) related to a Material Transaction Proposal or (iii) prior to the
    Xoom Stockholder Approval, withdraw or modify, in a manner adverse to NBC,
    the approval or recommendation of the Board of Directors of Xoom for the
    adoption of the Xenon 2 Merger Agreement or vote in favor of Xoom, as sole
    stockholder of Xenon 2, adopting the NMC Merger Agreement at the Xenon 2
    Stockholder Meeting. Notwithstanding the foregoing, if the Board of
    Directors of Xoom receives a Takeover Proposal without having violated
    SECTION 5.5(A) hereof, the Board of Directors of Xoom may, prior to
    obtaining the Xoom Stockholder Approval, to the extent it determines in good
    faith based on the advice of outside legal counsel that such action is
    required to comply with their fiduciary duties under applicable law, take
    any action specified in clauses (i), (ii) or (iii) above with respect to
    such Takeover Proposal, but in each case only (x) at a time that is at least
    five (5) business days after receipt by NBC of written notice from Xoom
    advising NBC that the Board of Directors of Xoom has resolved to take such
    action and (y) if Xoom simultaneously therewith terminates this Agreement
    pursuant to SECTION 9.1(G) hereof. Nothing contained in this Agreement shall
    prohibit Xoom or its board of directors from complying with Rules 14D-9 and
    14e-2 under the Exchange Act with respect to any Takeover Proposal.

        (c) As used herein, MATERIAL TRANSACTION PROPOSAL means any inquiry,
    proposal or offer from any Person relating to (i) the direct or indirect
    acquisition or purchase of 20% or more of the assets (based on the fair
    market value thereof) of Xoom and its Subsidiaries, taken as a whole, or of
    20% or more of any class of equity securities of Xoom or any of its
    Subsidiaries or any tender offer or exchange offer (including by Xoom or its
    Subsidiaries) that if consummated would result in any person beneficially
    owning 20% or more of any class of equity securities of Xoom or any of its
    Subsidiaries, or (ii) any merger, consolidation, business combination, sale
    of all or substantially all assets, recapitalization, liquidation,
    dissolution or similar transaction involving Xoom or any of its Subsidiaries
    other than the Transactions contemplated by this Agreement; PROVIDED,
    HOWEVER, that in no event shall any merger, consolidation, sale or similar
    transaction involving only Xoom and one or more of its wholly-owned
    subsidiaries or involving only any two or more of such wholly-owned
    subsidiaries be deemed to be a Material Transaction Proposal if such
    transaction is not entered into in violation of the terms of this
    Agreement.. As used herein, TAKEOVER PROPOSAL means any inquiry, proposal or
    offer from any Person relating to (A) any of the matters set forth in clause
    (i) of the definition of Material Transaction Proposal but replacing 20%
    with 50% each place 20% is used in such definition, (B) a sale of all or
    substantially all of the assets of Xoom and

                                     A-2-37
<PAGE>
    its Subsidiaries or (C) a merger or consolidation of Xoom as a result of
    which the stockholders of Xoom immediately prior to such transaction would
    not beneficially own immediately after such transaction 50% or more of the
    resulting or surviving entity (or the parent thereof).

        (d) The parties acknowledge that there may be no adequate remedy at law
    for a breach of SECTION 5.5 and that money damages may not be an adequate
    remedy for breach of such Section. Therefore, the parties agree that NBC and
    Xoom each shall have the right, in addition to any other rights it may have,
    to injunctive relief and specific performance in the event of any breach of
    this SECTION 5.5. The remedy set forth in the preceding two sentences is
    cumulative and shall in no way limit any other remedy any party hereto has
    at law, in equity or pursuant hereto.

    5.6  NON-SOLICITATION OF EMPLOYEES.  The parties hereto agree that beginning
on May 9, 1999 and continuing until one year after the Effective Time, no party
shall, directly or indirectly, solicit for employment any person who is now
employed by any of the other parties in an executive position, technical
position or is otherwise considered a key employee; PROVIDED, HOWEVER, that a
party shall not be precluded from hiring any such employee who (i) initiates
discussions regarding such employment without any direct or indirect
solicitation by such party, (ii) responds to any general public advertisement
placed by such party or (iii) has been terminated by the other party prior to
commencement of employment discussions between such party and the employee.

    5.7  AMENDMENTS TO SCHEDULES.  If no later than five business days prior to
the Closing Date, Xoom, Xenon 2, NBC, SNAP or GE Investments Sub becomes aware
of any fact or circumstance (whether or not it existed prior to May 9, 1999)
which would make any representation, warranty, covenant or agreement of such
party untrue, then such party shall be permitted to amend any Schedule to this
Agreement so as to identify such fact or circumstance to the extent necessary to
make such representation, warranty, covenant or agreement true and correct;
PROVIDED that if any such amendment, individually or in the aggregate with all
such other amendments, discloses facts and circumstances that constitute a
Material Adverse Effect, then notwithstanding anything to the contrary in this
Agreement, the other party (which shall be Xoom in the case of amendments by
NBC, SNAP or GE Investments Sub and shall be NBC in the case of amendments by
Xoom or Xenon 2) shall have the right to terminate this Agreement.
Notwithstanding the foregoing, any change to a Schedule that refers solely to an
item previously disclosed in the SEC Documents shall not be deemed to have a
Material Adverse Effect on Xenon if such reference is to a specific section of a
specific SEC Document.

                                   ARTICLE VI

<PAGE>
Securities Act. Each of the parties hereto shall promptly furnish to the other
party all information concerning itself, its stockholders and its Affiliates
that may be required or reasonably requested in connection with any action
contemplated by this SECTION 6.1. If any event relating to any party occurs, or
if any party becomes aware of any information, that should be disclosed in an
amendment or supplement to the Form S-4 or the Proxy Statement, then such party
shall inform the other thereof and shall cooperate with each other in filing
such amendment or supplement with the SEC and, if appropriate, in mailing such
amendment or supplement to the stockholders of Xoom. The Proxy Statement shall
include the recommendation of the Board of Directors of Xoom in favor of the
adoption of this Agreement and the Xenon 2 Merger Agreement and the approval of

    who is receiving registered shares of Class A Common Stock has an address of
    record or be exempt from such registration; and (ii) will be approved for
    quotation at the Effective Time on Nasdaq.

    time the Form S-4 becomes effective under the Securities Act, contain any
    untrue statement of a material fact or omit to state any material fact
    required to be stated therein or necessary in order to make the statements
    therein, in light of the circumstances under which they are made, not
    misleading;(ii) none of the information to be supplied by such party or its
    Affiliates for inclusion in the Proxy Statement will, at the time the Proxy
    Statement is mailed to the stockholders of Xoom or as of the Effective Time,
    contain any untrue statement of a material fact or omit to state any
    material fact required to be stated therein or necessary in order to make
    the statements therein, in light of the circumstances under which they were
    made, not misleading; and (iii) as to matters respecting such party, the
    Proxy Statement and the Form S-4 will comply as to form in all material
    respects with the provisions of the Securities Act and the Exchange Act, as
    applicable, and the rules and regulations promulgated by the SEC thereunder.

    6.2  STOCKHOLDER MEETING.  Xoom shall promptly after May 9, 1999 take all
action necessary in accordance with applicable law and its certificate of
incorporation and bylaws to duly call, hold and convene a meeting of Xoom's
stockholders (the "Xoom Stockholder Meeting") and a meeting of Xoom 2's
stockholder (the "Xenon 2 Stockholder Meeting). Except as required by the SEC or

effectiveness of the merger contemplated by the Xenon 2 Merger Agreement or (ii)
the adoption of this Agreement by the stockholder of Xenon 2 to be effected by a
written consent to action without a meeting. Neither NBC, Xenon 2 nor Xoom shall

advisable to secure the Stockholder

        (b)  EMPLOYEE BENEFIT PLANS

            (i) As of the Closing Date, except as otherwise expressly provided
       under the applicable employee benefit plan of NBC or its Affiliates (the
       "NBC Plans") the Transferred Employees shall cease to accrue further
       benefits under NBC Plans and shall immediately commence participation in
       the Xenon 2 plans (which, except as otherwise provided in this Agreement,
       shall initially be the Xoom Plans) on a basis no less favorable than
       similarly situated employees of Xenon 2 or Xoom. Xenon 2 or Xoom shall
       cause each Xenon 2 Plan to treat the prior service of each Transferred
       Employee with NBC or its affiliates as service rendered to Xenon 2 or
       Xoom for purposes of eligibility, vesting and benefit accrual (but not
       for purposes of benefit accruals) under any defined benefit plan to the
       same extent such service was taken into consideration under comparable
       NBC Plans.

            (ii) NBC shall retain responsibility for and continue to pay all
       medical, life insurance, disability and other welfare plan expenses and
       benefits for each Transferred Employee with respect to claims incurred by
       such Employees or their covered dependents prior to the Closing

                                     A-2-41
<PAGE>
       Date. Expenses and benefits with respect to claims incurred by
       Transferred Employees or their covered dependents on or after the Closing
       Date shall be the responsibility of Xenon 2. For purposes of this
       paragraph, a claim is deemed incurred when the services that are the
       subject of the claim are performed; in the case of life insurance, when
       the death occurs, in the case of long-term disability benefits, when the
       disability occurs and, in the case of a hospital stay, when the employee
       first enters the hospital.

           (iii) With respect to any welfare benefit plans (as defined in
       section 3(1) of ERISA) maintained by Xenon 2 or its Subsidiaries for the
       benefit of Transferred Employees and SNAP Employees on and after the
       Closing Date, Xenon 2 or its Subsidiaries shall use best efforts to (A)
       cause there to be waived any pre-existing condition limitations and (B)
       give effect, in determining any deductible and maximum out-of-pocket
       limitations, to claims incurred and amounts paid by, and amounts
       reimbursed to, such employees with respect to similar plans maintained by
       NBC for their benefit immediately prior to the Closing Date.

            (iv) NBC shall retain all assets and liabilities and obligations
       under NBC Plans with respect to the Transferred Employees.
       Notwithstanding the foregoing, Xenon 2 shall be responsible, with respect
       to Transferred Employees, for all accrued bonuses for the year of
       Closing.

            (v) With respect to any accrued but unused vacation time to which
       any Transferred Employee is entitled pursuant to the vacation policy
       applicable to such Transferred Employee immediately prior to the Closing
       Date (the "Vacation Policy"), Xenon 2 shall allow such Transferred
       Employee to use such accrued vacation; PROVIDED, HOWEVER, that if Xenon 2
       deems it necessary to disallow such Transferred Employee from taking such
       accrued vacation, Xenon 2 shall be liable for and pay in cash to each
       such Transferred Employee an amount equal to such vacation time in
       accordance with terms of the Vacation Policy.

    6.8  XENON 2 OPTIONS.  (a) Prior to the Effective Time, with respect to each
option to purchase shares of Xenon 2 into which options to purchase shares of
Xoom (a "Xoom Option"), which were granted pursuant to the Xoom 1998 stock
incentive plan (the "Xoom Option Plan") prior to May 9, 1999, were converted
(the "Converted Xoom Plan Options"), Xenon 2 shall cause the Administrator (as
defined in the Xoom Option Plan) to exercise its discretion to provide, and
shall take any other necessary action to provide, that each Converted Xoom Plan
Option shall vest and become exercisable with respect to all shares as to which
such options would otherwise have vested within 12 months following the
Effective Time. With respect to each option to purchase shares of Xenon 2 into
which Xoom Options, which were not granted pursuant to the Xoom Option Plan
prior to May 9, 1999, were converted (the "Converted Xoom Non-Plan Options"),
Xenon 2 shall take any necessary action to provide that such Converted Xoom
Non-Plan Options shall to the extent provided in the award agreement evidencing
such option vest and become exercisable with respect to 75% of the then unvested
portion of such Converted Xoom Non-Plan Option and any portion of a Converted
Xoom Non-Plan Option which remains unexercised upon the occurrence of the
Effective Time shall terminate upon the occurrence of the Effective Time. In
addition, with respect to each option to purchase shares of Xenon 2 into which
Xoom Options, which were granted after May 9, 1999, were converted (the
"Converted New Xoom Options"), Xenon 2 shall cause the Administrator to exercise
its discretion to provide, and shall take any other necessary action to provide,
that each option Converted New Xoom Option shall not immediately vest (but
rather, shall vest in accordance with its stated vesting schedule) with respect
to any of the shares subject thereto. Xenon 2 and Xoom acknowledge that the
transaction contemplated hereby shall constitute a "Corporate Transaction" for
purposes of both the Xoom Option Plan and the Converted Xoom Non-Plan Options
and the Administrator, the Board of Directors of Xoom and the Board of Directors
of Xenon 2 shall take all necessary action to effect the foregoing.

                                     A-2-42

        (b) In the event that any Xoom employee incurs an excise tax under
    Section 4999 of the Code as a result of the accelerated vesting of the Xoom
    Options pursuant to SECTION 6.8(A), Xenon 2 shall make available to such
    employee a loan (the "Tax Loan") in an amount sufficient to pay such excise
    tax. The determination of whether any such excise tax will be payable and
    the amount of such excise tax will be made by Xoom 2's independent auditors.
    The Tax Loan will (i) have a term of two years, and (ii) bear interest at
    the lowest permissible rate without imputation of income, compounded
    annually and (iii) to the extent not previously forgiven become immediately
    due and payable upon the termination of such employee's employment with
    Xenon 2 and its Affiliates for cause or due to such employee's voluntary
    resignation. The Tax Loan, will be forgiven with respect to 1/24 of the
    initial principal amount of the Tax Loan (together with accrued interest
    thereon) on the last day of each 1 month anniversary of the Effective Time
    if the employee has remained continually employed with Xenon 2 and its
    Affiliates through such date or if such employee's employment with Xenon 2
    and its Affiliates is terminated without cause or due to the employee's
    death or disability.

    6.9  SNAP INDEBTEDNESS.  Immediately following Closing, Xenon 2 will repay
and terminate the commitments with respect to the indebtedness for money
borrowed (including all interest, fees and other amounts payable in respect
thereof) set forth on SCHEDULE 6.9 and Xenon 2 shall use its best efforts to
cause the guarantee of such indebtedness by General Electric Company to be fully
released. Neither SNAP nor NBC or any of its Subsidiaries shall be required to
repay prior to Closing any indebtedness of SNAP, including any incurred from and
after May 9, 1999 in accordance with the terms of this Agreement.

    6.10  ORGANIZATION OF CNBC.COM.  NBC shall organize an entity and contribute
the assets, properties and other rights set forth on SCHEDULE 6.10 to such
entity on or before the Closing Date.

    6.11  TAX COOPERATION AND CONSISTENT REPORTING.

        (a) Xenon 2 and NBC agree to furnish or cause to be furnished to each
    other, upon request, as promptly as practicable, such information and
    assistance relating to the Contributed Assets as is reasonably necessary for
    the filing of all Tax Returns, and making of any election related to Taxes,
    the preparation for any audit by any Tax Authority, and the prosecution or
    defense of any claim, suit or proceeding relating to any Tax Return. Xenon 2
    and NBC will cooperate with each other in the conduct of any audit or other
    proceeding related to Taxes and all other Tax matters relating to the
    Contributed Assets, and each will execute and deliver such powers of
    attorney and other documents as are necessary to carry out the intent of
    this SECTION 6.11.

        (b) Unless there has been a Final Determination to the contrary, NBC,
    Xenon 2 and Xoom covenant and agree, for all Tax purposes including all Tax
    Returns and any Tax controversies to (and to cause any Affiliate or
    successor to their assets or business to) take each of the positions set
    forth below (and not to take any positions inconsistent therewith):

            (i) The transfer of the Contributed Assets pursuant to the Agreement
       will qualify under Section 351(a) of the Code.

            (ii) None of the consideration received for the Contributed Assets
       pursuant to the Agreement other than Convertible Note #1 will be treated
       as Other Property or Money.

           (iii) None of the Class A Common Stock or Class B Common Stock issued
       to NBC or CNET pursuant to the terms of the Agreement will be paid or
       issued for services.

            (iv) The tax basis of each Contributed Asset to be received by Xenon
       2 will be the same as the tax basis of such asset in the hands of the
       transferor increased by the amount of any gain recognized by the
       transferor on the transfer of such asset.

                                     A-2-43
<PAGE>
            (v) The holding period of each Contributed Asset will include the
       period during which such asset was held by the transferor.

            (vi) Neither Xenon 2, Xoom, any affiliate thereof, nor any successor
       to their assets or businesses will be entitled to claim any deduction in
       respect of any assumed Liability to the extent previously deducted by the
       transferor.

        (c) Xenon 2 represents, covenants and agrees that (A) it has no plan or
    intention to (i) issue additional shares of stock after the Merger, or take
    any other action, that would result in NBC, NBC Multimedia, CNBC, CNET and
    the Xoom shareholders losing control of Xenon 2, (ii) liquidate or merge
    Xenon 2; (iii) sell or otherwise dispose of any of its assets (or of any of
    the assets acquired from NBC Multimedia), except for dispositions made in
    the ordinary course of business, transfers permitted under Section
    368(a)(2)(C) of the Code, or transfers prescribed by Section 1.368-1(d) that
    will not affect Xoom 2's satisfaction of the "continuity of business
    enterprise" requirement under Section 368 of the Code for purposes of
    qualifying the Merger as a "reorganization" under said section, and (iv)
    reacquire any of the shares of its stock issued pursuant to this Agreement,
    and (B) the historic business of NBC Multimedia will be continued or a
    significant portion of NBC Multimedia's historic business assets will be
    used in a business.

        (d) (i) NBC and Xenon 2 agree to report to the other any communication
    from or with the Internal Revenue Service which relates in any way to the
    characterization of the transactions contemplated by the Agreement.
    Notwithstanding any such communication, Xenon 2 and Xoom covenant and agree
    to (and to cause any Affiliate or successor to their assets or business to)
    continue to take each of the positions specified in SECTION 6.11(B) for all
    Tax purposes (unless there has been a Final Determination contrary to such
    position).

            (ii) Without limiting the generality of SECTION 6.11(D)(I), (A) NBC
       will file with its federal income tax return for the taxable year in
       which the Agreement is consummated (which tax return shall be timely
       filed) the information required by Treas. Reg Section 1.351-3(a), and
       will deliver a copy of that statement to Xenon 2 within ten days
       thereafter, and (B) Xenon 2 will file with its federal income tax return
       for the taxable year in which the Agreement is consummated (which tax
       return shall be timely filed) the information required by Treas. Reg
       Section 1.351-3(b), and will deliver a copy of that statement to NBC
       within ten days thereafter. Within ninety days after the Closing Date,
       NBC will deliver to Xenon 2 all of the cost and other basis information
       relating to the Contributed Assets and assumed Liabilities for federal
       income tax purposes reasonably required for Xenon 2 to prepare the
       statement required by Treas. Reg. Section 1.351-3(b)(2). Such information
       will be delivered in the form normally maintained by NBC and will include
       reasonably complete data relating to the tax basis, year of acquisition,
       depreciable life, and amount and method of depreciation of tangible and
       intangible property. NBC and Xenon 2 also will maintain such records as
       are required by Treas. Reg. Section 1.351-3(c).

           (iii) Without limiting the generality of SECTION 6.11(D)(I), (A)
       Xenon 2 and NBC Multimedia will comply with the record-keeping and
       information filing requirements of Section 1.368-3 of the Treasury
       Regulations with respect to the Merger, and (B) Xenon 2 will file with
       its federal income tax return for the taxable year in which the Agreement
       is consummated (which tax return shall be timely filed) the information
       required by Treasury Regulations Section 1.351-3(b) and maintain such
       records as are required by Treasury Regulations Section 1.351-3(c) with
       respect to the Merger.

       Multimedia on the transfers set forth in SECTIONS 2.2 and 2.3 of this
       Agreement shall be allocated and reported for all tax purposes by Xenon 2
       consistent with and based on an allocation schedule to be provided to
       Xenon 2 by NBC.

    6.12  TAX BENEFIT PAYMENTS.

        (a) If a Final Determination is made contrary to any of the positions
    described in 6.11(b)(i), (ii), or (iii), then (in addition to any other
    remedies which may be available to NBC but without duplication thereof)
    Xenon 2 will pay to NBC for each Post-Closing Tax Period an amount equal to
    the excess of (A) the liability for federal, state and local Taxes to which
    Xenon 2, Xoom or any other Affiliates or any successor to their assets or
    businesses (collectively, the "Taxpayer") would have been subject for all
    Post-Closing Tax Periods in each relevant jurisdiction had the positions
    described in SECTION 6.11(B)(I), SECTION 6.11(B)(II) and SECTION
    6.11(B)(III) been sustained (and had Xenon 2 not been required to make any
    payments pursuant to this Section 6.12), over (B) the Taxpayer's actual
    liability for such Taxes for such periods. Such payment will be due (subject
    to a ten business-day grace period) when, as, and to the extent the Taxpayer
    derives an actual benefit (in the form of any refund, reduction in Tax
    liability, or otherwise) as the result of such excess. If any payment
    required under this SECTION 6.12(A) for any Post-Closing Tax Period is not
    made on or before the due date (without extensions) of the return of such
    period, then such payment will be made together with interest at the rate
    per annum determined from time to time under Section 6621(a)(2) of the Code
    compounded daily for the period from such due date to the date on which the
    payment is actually made.

        (b) In addition, Xenon 2 will pay to NBC, no later than ten business
    days after each date on which the Taxpayer receives a refund of federal,
    state or local Taxes for a Pre-Closing Tax Period, the excess of such
    refunds over such refunds to which the Taxpayer would have been entitled had
    the positions described in SECTION 6.11(B)been sustained (and had Xenon 2
    not been required to make any payments under this SECTION 6.12). If any
    payment required under this SECTION 6.12(B) is not made on or before the
    date such payment is due, then such payment will be made together with
    interest at the rate per annum determined from time to time under Section
    6621(a)(2) of the Code compounded daily for the period from the date such
    payment was due to the date on which such payment is actually made.

        (c) In the event of any adjustment to the Taxpayer's liability for
    federal, state or local Taxes or entitlement to a refund, as a result of
    audit, carryover, or otherwise, the amounts previously payable under this
    SECTION 6.12 will be appropriately adjusted and Xenon 2 or NBC, as the case
    may be, will pay to the other the amount, required as a result of such
    adjustment, together with interest at the rate per annum determined from
    time to time under Section 6621(a)(2) of the Code compounded daily for the
    period from the original payment date affected by the adjustment to the date
    on which the payment is made. At the time of any payment under this SECTION
    6.12 (or at the request of NBC if Xenon 2 has determined that no payment is
    due), Xenon 2 will submit a schedule showing in reasonable detail its
    calculation of the payment to be made (or the basis for its determination
    that no payment is due). Any dispute concerning the calculation of payments
    due under this SECTION 6.12 will be resolved by the Independent Accountants.

        (d) Any payment to NBC under this SECTION 6.12 will be allocated between
    principal and interest for purposes of Section 483, Section 1273, and any
    other relevant provision of the Code by using as a discount rate the rate
    per annum determined from time to time under Section 6621(a)(2) of the Code
    compounded daily for the period from the date of Closing to the date on
    which the payment is made. The portion of any such payment created as
    principal will be treated as additional exchange consideration. Any payment
    to Xenon 2 under this SECTION 6.12 (other than interest) will be treated as
    a reduction of the exchange consideration.

        (e) NBC will pay (i) any fees or other amounts due to the Independent
    Accountants in respect of the resolution of any dispute pursuant to SECTION
    6.12(C), and (ii) all reasonable costs (including the reasonable internal
    costs of Xenon 2 or any Affiliate or successor thereto) incurred by Xenon 2
    (or by such Affiliate or successor) to comply with the provisions of this
    SECTION 6.12.

    6.13  XOOM CASH.  As long as the Effective Time occurs on or prior to
September 30, 1999, Xoom covenants and agrees immediately prior to the Effective
Time that it will have cash, net of outstanding indebtedness of Xoom, in an
amount at least equal to the sum of $230 million less any cash used in
connection with acquisitions made in accordance with the terms of SECTION 5.1;
PROVIDED that if the Effective Time occurs after that date, the foregoing amount
shall also be less $7.5 million for each month after September 30, 1999 and
prior to the Effective Time.

    6.14  TRANSITION SERVICES.  Promptly after May 9, 1999, NBC, Xoom and Xenon
2 shall use their good faith efforts to negotiate a transition services
agreement pursuant to which NBC shall provide certain administrative and support
services and facilities relating to the NBC Multimedia Businesses to Xenon 2 for
a transition period after the Effective Time on terms mutually acceptable to the
parties.

    6.15  CONVERSION OF NBC'S CLASS A COMMON STOCK.  On the Closing Date, any
Class A Common Stock purchased pursuant to the Stock Purchase Agreement, dated
as of June 11, 1999, between Xoom and NBC held by NBC or its Affiliates will be
automatically converted into Class B Common Stock pursuant to the certificate of
incorporation attached hereto as Exhibit 3.5. As soon as reasonably practicable
after the Effective Time, NBC or its Affiliates, as the case may be, shall
deliver any certificates representing such Class A Common Stock to Xenon 2 and
NBC or its Affiliates, as the case may be, shall be entitled to receive in
exchange a certificate representing the same number of shares of Class B Common
Stock, which certificate shall, until such time as the same is no longer
required hereunder or under the applicable requirements of the Securities Act or
applicable state securities laws, bear the legend set forth in Section 3.8(d).

indemnify and hold harmless Xenon 2 and its Affiliates and each of the
foregoing's respective directors, officers, employees and agents, heirs,
executors, successors and assigns of any of the foregoing from and against any
and all Losses and Expenses suffered or incurred by any such indemnified Person
arising from, relating to or otherwise in respect of any breach of the
representations and warranties set forth in SECTION 4.1(C)(III) and SECTION
4.1(V) of this Agreement.

    8.3  CLAIMS PROCEDURE.  (a) If a claim by a third party is made against an
indemnified Person hereunder, and if such indemnified Person intends to seek
indemnity with respect thereto under this Article, such indemnified Person shall
promptly notify the indemnifying Person in writing of such claims setting forth
such claims in reasonable detail (the CLAIM NOTICE), provided that failure of
such indemnified Person to give prompt notice as provided herein shall not
relieve the indemnifying Person of any of its obligations hereunder, except to
the extent that the indemnifying Person is materially prejudiced by such
failure. The indemnifying Person shall have twenty (20) days after receipt of
such notice (the NOTICE PERIOD) to undertake, through counsel of its own
choosing, subject to the reasonable approval of such indemnified Person, and at
its own expense, the settlement or defense thereof, and the indemnified Person
shall cooperate with it in connection therewith; PROVIDED, HOWEVER, that the
indemnified Person may participate in such settlement or defense through counsel
chosen by such indemnified Person, PROVIDED that the fees and expenses of such
counsel shall be borne by such indemnified Person. If the indemnifying Person
shall assume the defense of a claim, it shall not settle such claim without the
prior written consent of the indemnified Person, unless (i) such settlement
includes as an unconditional term thereof the giving by the claimant of a
release of the indemnified Person from all Liability with respect to such claim
or (ii) such settlement does not involve the imposition of equitable remedies or
the imposition of any material obligations on such indemnified Person other than
financial obligations for which such indemnified party will be indemnified
hereunder. If the indemnifying Person shall assume the defense of a claim, the
fees of any separate counsel retained by the indemnified Person shall be borne
by such indemnified Person unless there exists a material conflict between them
as to their respective legal defenses (other than one that is of a monetary
nature), in which case the indemnified Person shall be entitled to retain one
law firm (plus any necessary local counsel) as its separate counsel, the
reasonable fees and expenses of which shall be reimbursed by the indemnifying
Person. If the indemnifying Person does not notify the indemnified Person within
twenty (20) days after the receipt of the indemnified Person's notice of a claim
of indemnity hereunder that it elects to undertake the defense thereof, the
indemnified Person shall have the right to contest, settle or compromise the
claim but shall not thereby waive any right to indemnity therefor pursuant to
this Agreement.

        (b)  OTHER CLAIMS.  In the event the indemnified party should have a
    claim against the indemnifying party hereunder which does not involve a
    claim or demand being asserted against or sought to be collected from it by
    a third party, the indemnified party shall promptly send a Claim Notice with
    respect to such claim to the indemnifying party. If the indemnifying party
    does not notify the indemnified party within the Notice Period that they
    dispute such claim, the amount of such claim shall be conclusively deemed a
    liability of the indemnifying party hereunder.

    8.4  EXCLUSIVE REMEDY.  From and after the Closing, the indemnification
obligations under this ARTICLE VIII and the obligations of NBC in SECTION 9.2
constitute the sole and exclusive remedy of each party for any breach of, or
inaccuracy in, any representation or warranty of another party contained in this
Agreement or in any certificate delivered pursuant hereto or any breach of any
covenant in this Agreement in each case to the extent they survive the Closing.

    material default or breach hereunder and PROVIDED, FURTHER, that the right
    to terminate this Agreement under this clause (b) shall not be available to

    been the cause of, or resulted in, the failure to consummate the
    transactions contemplated by this Agreement on or before such date;

        (c) by either NBC or Xenon 2 if (i) any Governmental Authority, the
    consent or approval of which is required for the consummation of the

    taken and have been unsuccessful or (ii) any court of competent jurisdiction
    in the United States shall have issued a final and unappealable permanent
    injunction, order, judgment or other decree (other than a temporary

    consummation of the transactions contemplated hereby, PROVIDED that the
    party seeking to terminate this Agreement under this clause (c) is not then
    in material breach of this Agreement and PROVIDED, FURTHER, that the right

    approval or recommendation of this Agreement, the Xenon 2 Merger Agreement
    or any of the transactions contemplated hereby or thereby;

        (f) by NBC if the Board of Directors of Xoom shall have accepted or
    recommended a Takeover Proposal or shall have resolved to do so;

        (g) by Xoom or Xenon 2, prior to the receipt of the Xoom Stockholder
    Approval, on five business days written notice, if, Xoom receives, without
    violating its obligations under SECTION 5.5 hereof, a bona fide Takeover
    Proposal from a third party on terms which the Board of Directors of Xoom
    (i) determines in good faith and after consultation with a financial advisor
    of nationally recognized reputation to be more favorable to the Xoom
    stockholders than the transactions contemplated by this Agreement and (ii)
    concludes in good faith based on the advice of outside legal counsel that
    termination of this Agreement is required to comply with its fiduciary
    duties under applicable law; or

        (h) by either NBC or Xenon 2 in the event there has been a material
    default or breach by (x) NBC, where Xenon 2 is terminating this Agreement,

    termination of the Xenon 2 Merger Agreement.

    9.2  EFFECT OF TERMINATION.  In the event of any termination of the
Agreement as provided in SECTION 9.1 hereto, this Agreement shall forthwith
become wholly void and of no further force and effect (except SECTION 5.6,

transactions contemplated by this Agreement after all of the conditions to
closing set forth in SECTION 7.1 and SECTION 7.2 have been satisfied, within 2
business days of the termination of this Agreement by Xenon 2, NBC shall pay to
Xenon 2 $475 million, which amount shall constitute the sole and exclusive

pursuant to which, among other things, the parties thereto have agreed that (i)
Grantee will contribute or cause its subsidiaries to contribute to NMC certain
assets, (ii) NMC will merge with and into Xenon 2, with Xenon 2 as the surviving

    WHEREAS, as a condition to Grantee's entering into the NMC Merger Agreement

and agreements set forth herein and in the NMC Merger Agreement and intending to
be legally bound, the parties hereto agree as follows:

    1.  THE OPTION.  (a) Issuer hereby grants to Grantee an unconditional,
irrevocable option (the "OPTION") to purchase, subject to the terms hereof, up
to 3,415,249 fully paid and nonassessable shares of Issuer's common stock, par
value $0.0001 per share (the "COMMON STOCK"), at a price of $73.50 per share
(such price, as adjusted if applicable, the "OPTION PRICE"); PROVIDED that in no
event shall the number of shares of Common Stock for which this Option is
exercisable exceed 19.9% of the issued and outstanding shares of Common Stock at
the time of exercise without giving effect to any shares subject or issued
pursuant to the Option. The number of shares of Common Stock that may be
received upon the exercise of the Option and the Option Price are subject to
adjustment as herein set forth.

                                     B-1-1
<PAGE>
    (b) In the event that any additional shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (except for shares
issued pursuant to this Agreement), the number of shares of Common Stock subject
to the Option shall be increased so that, after such issuance, such number
equals 19.9% of the number of shares of Common Stock then issued and outstanding
without giving effect to any shares subject or issued pursuant to the Option.
Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be
deemed to authorize Issuer to breach any provision of the Merger Agreements.

    2.  EXERCISE; TRANSFER OF SHARES; CLOSING.  (a) Grantee and/or any person
that shall become a holder of all or part of the Option in accordance with the
terms of this Agreement (each such person being referred to herein as the
"Holder") may exercise the Option, in whole or part, and from time to time, but
only following an Initial Triggering Event (as defined below) that occurs prior
to the occurrence of an Exercise Termination Event (as defined below).

    (b) Each of the following shall be an "EXERCISE TERMINATION EVENT":

        (i) the Effective Time (as defined in the NMC Merger Agreement);

        (ii) termination of the NMC Merger Agreement in accordance with the
    provisions thereof if such termination occurs prior to the occurrence of an
    Initial Triggering Event, except a termination by Grantee pursuant to
    Section 9.1(h) of the NMC Merger Agreement; and

       (iii) the passage of 12 months after termination of the NMC Merger
    Agreement (or such later period as provided in Section 10) if such
    termination (A) follows or is concurrent with the occurrence of an Initial
    Triggering Event or (B) is a termination by Grantee pursuant to Section
    9.1(h) of the NMC Merger Agreement.

    (c) The term "INITIAL TRIGGERING EVENT" shall mean any of the following
events or transactions (other than the transactions contemplated by Articles II
and III of the Xenon 2 Merger Agreement) occurring after the date hereof:

        (i) Issuer, without having received Grantee's prior written consent,
    shall have entered into an agreement to engage in an Acquisition Transaction
    (as defined below) with any person (the term "person" for purposes of this
    Agreement having the meaning assigned thereto in Sections 3(a)(9) and
    13(d)(3) of the Securities Exchange Act of 1934, as amended (the "1934
    Act"), and the rules and regulations thereunder) other than Grantee or any
    of its subsidiaries or affiliates (each a "Grantee Party") or the Board of
    Directors of Issuer shall have recommended that the stockholders of Issuer
    approve or accept any Acquisition Transaction (other than the transactions
    referred to in the NMC Merger Agreement). For purposes of this Agreement,
    "Acquisition Transaction" shall mean any (x) direct or indirect acquisition
    or purchase of 20% or more of the assets (based on the fair market value
    thereof) of Issuer and its subsidiaries, taken as a whole, or of 20% or more
    of any class of equity securities of Issuer or any of its subsidiaries or
    any tender offer or exchange offer (including by Issuer or its subsidiaries)
    that if consummated would result in any person having beneficial ownership
    (the term "beneficial ownership" for purposes of this Agreement having the
    meaning assigned thereto in Section 13(d) of the Exchange Act, and the rules
    and regulations thereunder) of 20% or more of any class of equity securities
    of Issuer or any of its subsidiaries, or (y) any merger, consolidation,
    business combination, sale of all or substantially all assets,
    recapitalization, liquidation, dissolution or similar transaction involving
    Issuer or any of its subsidiaries; PROVIDED, HOWEVER, that in no event shall
    any merger, consolidation, sale or similar transaction involving only the
    Issuer and one or more of its wholly-owned subsidiaries or involving only
    any two or more of such wholly-owned subsidiaries, be deemed to be an
    Acquisition Transaction if such transaction is not entered into in violation
    of the terms of the NMC Merger Agreement;

<PAGE>
        (ii) Issuer, without having received Grantee's prior written consent,
    shall have authorized, recommended, proposed or publicly announced its
    intention to authorize, recommend or propose, to engage in an Acquisition
    Transaction with any person other than Grantee or a Grantee Party, or the
    Board of Directors of Issuer shall have failed to recommend or shall have
    publicly withdrawn or modified, or publicly announced its intention to
    withdraw or modify, in any manner adverse to Grantee, its recommendation
    that the stockholders of Issuer adopt the Xenon 2 Merger Agreement in
    anticipation of engaging in an Acquisition Transaction;

       (iii) The stockholders of Issuer shall have voted and failed to adopt the
    Xenon 2 Agreement, or shall have voted and failed to instruct Issuer, as
    sole stockholder of Xenon 2, to vote to adopt the NMC Merger Agreement, at a
    meeting which has been held for that purpose or at any adjournment or
    postponement thereof, or such meeting shall not have been held in violation
    of the NMC Merger Agreement or shall have been canceled prior to termination
    of the NMC Merger Agreement if, prior to such meeting (or if such meeting
    shall not have been held or shall have been canceled, prior to such
    termination), any person (other than the Grantee or a Grantee Party) shall
    have made a bona fide proposal to Issuer or its stockholders by public
    announcement or written communication that is or becomes the subject of
    public disclosure to engage in an Acquisition Transaction;

        (iv) (a) Any person other than Grantee, any Grantee Party or any Issuer
    subsidiary acting in a fiduciary capacity in the ordinary course of its
    business shall have acquired beneficial ownership or the right to acquire
    beneficial ownership of, or shall have commenced (as such term is defined in
    Rule 14d-2 under the Exchange Act) or filed a registration statement with
    respect to a tender offer or exchange offer to purchase any shares of Common
    Stock such that upon consummation of such offer such person would acquire
    beneficial ownership of, 20% or more of the then outstanding shares of
    Common Stock or (b) any group (the term "group" having the meaning assigned
    in Section 13(d)(3) of the Exchange Act), other than a group of which the
    Grantee or any Grantee Party is a member, shall have been formed that
    beneficially owns 20% or more of the shares of Common Stock then
    outstanding; or

        (v) After a third party shall have made a bona fide proposal to Issuer
    or its stockholders by public announcement or written communication that is
    or becomes the subject of public disclosure to engage in an Acquisition
    Transaction, Issuer shall have terminated the NMC Merger Agreement pursuant
    to Section 9.1(g) thereof or shall have breached any covenant or obligation
    contained in the Merger Agreements and such breach (x) would entitle a party
    other than Issuer to terminate such Merger Agreement and (y) shall not have
    been cured prior to the Notice Date (as defined below).

    (d) The term "SUBSEQUENT TRIGGERING EVENT" shall mean either of the
following events or transactions occurring after the date hereof:

        (i) The acquisition by any person or by a group of beneficial ownership
    of 50% or more of the then outstanding Common Stock; or

        (ii) The Issuer, without having received Grantee's prior written
    consent, shall have entered into an agreement relating to a Takeover
    Proposal (as defined in the NMC Merger Agreement) with any person other than
    Grantee or any Grantee Party or the Board of Directors of Issuer shall have
    accepted or approved or recommended that the stockholders of Issuer accept
    or approve a Takeover Proposal or shall have resolved to do any of the
    foregoing.

    (e) Issuer shall notify Grantee promptly in writing of the occurrence of any
Initial Triggering Event or Subsequent Triggering Event of which it has notice
(any such event, a "TRIGGERING EVENT"), it being understood that the giving of
such notice by Issuer shall not be a condition to the right of the Holder to
exercise the Option.

                                     B-1-3
<PAGE>
    (f) In the event the Holder is entitled to and wishes to exercise the option
(or any portion thereof), it shall send to Issuer a written notice (the date of
which being herein referred to as the "NOTICE DATE") specifying (i) the total
number of shares it will purchase pursuant to such exercise and (ii) a place and
date not earlier than three business days nor later than 60 business days from
the Notice Date for the closing of such purchase (the "CLOSING DATE"); PROVIDED
that if prior notification to or approval of any regulatory agency is required
in connection with such purchase, the Holder shall promptly file the required
notice or application for approval and shall expeditiously process the same and
the period of time that otherwise would run pursuant to this sentence shall run
instead from the date on which any required notification periods have expired or
been terminated or such approvals have been obtained and any requisite waiting
period or periods shall have passed. Any exercise of the option shall be deemed
to occur on the Notice Date relating thereto.

    (g) At the closing referred to in subsection (f) of this Section 2, the
Holder shall pay to Issuer the aggregate purchase price for the shares of Common
Stock purchased pursuant to the exercise of the Option in immediately available
funds by wire transfer to a bank account designated by Issuer; PROVIDED that
failure or refusal of Issuer to designate such a bank account shall not preclude
the Holder from exercising the Option.

    (h) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (g) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares of Common Stock purchasable hereunder, and
the Holder shall deliver to Issuer a copy of this Agreement and a letter
agreeing that the Holder will not offer to sell or otherwise dispose of such
shares in violation of applicable law or the provisions of this Agreement.

    (i) Certificates for Common Stock delivered at a closing hereunder may be
endorsed with a restrictive legend that shall read substantially as follows:

       "The transfer of the shares represented by this certificate is
       subject to certain provisions of an agreement between the
       registered holder hereof and Issuer and to resale restrictions
       arising under the Securities Act of 1933, as amended. A copy of
       such agreement is on file at the principal office of Issuer and
       will be provided to the holder hereof without charge upon receipt
       by Issuer of a written request therefor."

    It is understood and agreed that: (i) the reference to the resale
restrictions of the Securities Act of 1933, as amended (the "1933 ACT"), in the
above legend shall be removed by delivery of substitute certificate(s) without
such reference if the Holder shall have delivered to Issuer a copy of a letter
from the staff of the SEC, or an opinion of counsel, in form and substance
reasonably satisfactory to Issuer, to the effect that such legend is not
required for purposes of the 1933 Act; (ii) the reference to the provisions of
this Agreement in the above legend shall be removed by delivery of substitute
certificate(s) without such reference if the shares of Common Stock delivered
pursuant hereto have been sold or transferred in compliance with the provisions
of this Agreement under circumstances that do not require the retention of such
reference; and (iii) the legend shall be removed in its entirety if the
conditions in the preceding clauses (i) and (ii) are both satisfied. In
addition, such certificates shall bear any other legend as may be required by
law.

    (j) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (f) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder.

                                     B-1-4
<PAGE>
    3.  COVENANTS OF ISSUER.  In addition to its other agreements and covenants
herein, Issuer agrees: (i) that it shall at all times maintain, free from
subscriptive or preemptive rights, sufficient authorized but unissued or
treasury shares of Common Stock so that the Option may be exercised without
additional authorization of Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to purchase Common
Stock; (ii) that it will not, by an amendment to its certificate of
incorporation or by-laws or through reorganization, consolidation, merger,
dissolution or sale of assets, or by any other voluntary act, avoid or seek to
avoid the observance or performance of any of the covenants, stipulations or
conditions to be observed or performed hereunder by Issuer; (iii) promptly to
take all action as may from time to time be required (including complying with
all premerger notification, reporting and waiting period requirements specified
in 15 U.S.C. Section 18a and regulations promulgated thereunder) in order to
permit the Holder to exercise the Option and Issuer to duly and effectively
issue shares of Common Stock pursuant hereto; (iv) promptly to take all action
provided herein to protect the rights of the Holder against dilution; and (v)
not to enter or agree to enter into any agreement for an Acquisition Transaction
or a Takeover Proposal unless the other party or parties thereto agree to assume
in writing all of Issuer's obligations hereunder; PROVIDED that nothing in this
Section 3 or elsewhere in this Agreement shall be deemed to authorize Issuer to
breach any provision of the Merger Agreements. Notwithstanding any notice of
revocation delivered pursuant to the proviso to Section 7(c), a Holder may
require such other party or parties to perform Issuer's obligations under
Section 7(a) unless such other party or parties are prohibited by law or
regulation from such performance.

    4.  EXCHANGE; REPLACEMENT.  This Agreement and the Option granted hereby are
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender of this Agreement at the principal office of Issuer, for other
Agreements providing for options of different denominations entitling the holder
thereof to purchase, on the same terms and subject to the same conditions as are
set forth herein, in the aggregate the same number of shares of Common Stock
purchasable hereunder. The terms "AGREEMENT" and "OPTION" as used herein include
any Agreements and related options for which this Agreement (and the Option
granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this
Agreement, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like
tenor and date. Any such new Agreement executed and delivered shall constitute
an additional contractual obligation on the part of Issuer, whether or not the
Agreement so lost, stolen, destroyed or mutilated shall at any time be
enforceable by anyone.

    5.  ADJUSTMENTS.  In addition to the adjustment in the number of shares of
Common Stock that are purchasable upon exercise of the option pursuant to
Section 1 of this Agreement, the number of shares of Common Stock purchasable
upon the exercise of the Option and the Option Price shall be subject to
adjustment from time to time as provided in this Section 5. In the event of any
change in, or distributions in respect of, the Common Stock by reason of stock
dividends, reclassifications, split-ups, mergers, recapitalizations,
combinations, subdivisions, conversions, exchanges of shares, distributions on
or in respect of the Common Stock, or the like, the type and number of shares of
Common Stock purchasable upon exercise hereof and the Option Price shall be
appropriately adjusted in such manner as shall fully preserve the economic
benefits provided hereunder and proper provision shall be made in any agreement
governing any such transaction to provide for such proper adjustment and the
full satisfaction of the Issuer's obligations hereunder.

    6.  REGISTRATION.  Upon the occurrence of a Triggering Event that occurs
prior to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within 12 months (or such later period as provided in Section 10) of
such Triggering Event (whether on its own behalf or on behalf of any subsequent
holder of this Option (or part thereof) or any of the shares of Common Stock
issued pursuant hereto), file within 60 days (which period may be tolled by up
to 60 consecutive days if the

                                     B-1-5
<PAGE>
Issuer, in its good faith reasonable judgment after having consulted with
outside counsel, determines that such registration would be materially adverse
to the Issuer) and keep current a shelf registration statement under the 1933
Act covering this Option and any shares issued and issuable pursuant to this
Option and shall use its reasonable best efforts to cause such registration
statement to become effective and remain current in order to permit the sale or
other disposition of this option and any shares of Common Stock issued upon
total or partial exercise of this Option ("OPTION SHARES") in accordance with
any plan of disposition requested by Grantee. Issuer will use its reasonable
best efforts to cause such registration statement promptly to become effective
and then to remain effective for a period not in excess of 180 days from the day
such registration statement first becomes effective or such shorter time as may
be reasonably necessary, in the judgment of the Grantee or the Holder, to effect
such sales or other dispositions. Grantee shall have the right to demand two
such registrations. In connection with such registrations, the Issuer shall bear
its attorneys' fees and any accounting fees, printing and mailing costs and SEC,
NASD, Nasdaq, state blue sky and other filing fees and Grantee shall bear its
discounts or commissions and brokers fees and the fees and disbursements of
Grantee's counsel related thereto. The foregoing notwithstanding, if, at the
time of any request by Grantee for registration of the Option or Option Shares
as provided above, Issuer is in registration with respect to an underwritten
public offering of shares of Common Stock, and if in the good faith judgment of
the managing underwriter or managing underwriters, or, if none, the sole
underwriter or underwriters, of such offering the inclusion of the Holder's
Option or Option Shares would interfere with the successful marketing of the
shares of Common Stock offered by Issuer, the number of Option Shares otherwise
to be covered in the registration statement contemplated hereby may be reduced;
PROVIDED, HOWEVER, that after any such required reduction the number of Option
Shares to be included in such offering for the account of the Holder shall
constitute at least 25% of the total number of shares to be sold by the Holder
and Issuer in the aggregate; and PROVIDED FURTHER, HOWEVER, that if such
reduction occurs, then the Issuer shall file a registration statement for the
balance of such shares of Common Stock issuable pursuant to this Option as
promptly as practical following such reduction and no reduction in the number of
shares of Common Stock to be sold by the Holder shall thereafter occur. Each
such Holder shall provide all information reasonably requested by Issuer for
inclusion in any registration statement to be filed hereunder. If requested by
any such Holder in connection with such registration, Issuer shall become a
party to any underwriting agreement relating to the sale of such shares, but
only to the extent of obligating itself in respect of representations,
warranties, indemnities, opinions of counsel and other agreements customarily
included in secondary offering underwriting agreements for the Issuer. Upon
receiving any request under this Section 6 from any Holder, Issuer agrees to
send a copy thereof to any other person known to Issuer to be entitled to
registration rights under this Section 6, in each case by promptly mailing the
same, postage prepaid, to the address of record of the persons entitled to
receive such copies. Notwithstanding anything to the contrary contained herein,
in no event shall Issuer be obligated to effect more than two registrations
pursuant to this Section 6 by reason of the fact that there shall be more than
one Holder as a result of any assignment or division of this Agreement.

    7.  REPURCHASE OF OPTION AND/OR OPTION SHARES.  (a) At any time after the
occurrence of a Repurchase Event (as defined below), (i) following a request of
the Holder, given prior to an Exercise Termination Event (or such later period
as provided in Section 10), Issuer (or any successor thereto) shall repurchase
the Option from the Holder at a price (the "OPTION REPURCHASE PRICE") equal to
the amount by which (A) the Market/Offer Price (as defined below) exceeds (B)
the Option Price, multiplied by the number of shares for which this Option may
then be exercised and (ii) at the request of the owner of Option Shares from
time to time (the "OWNER"), delivered within 90 days of such occurrence (or such
later period as provided in Section 10), Issuer shall repurchase such number of
the Option Shares from the Owner as the Owner shall designate at a price (the
"OPTION SHARE REPURCHASE PRICE") equal to the Market/Offer Price multiplied by
the number of Option Shares so designated; PROVIDED, HOWEVER, that the Option
Repurchase Price and the Option Share Repurchase Price, individually and in the
aggregate and as paid from time to time, shall be subject to the limitations on

                                     B-1-6
<PAGE>
Total Profit set forth in Section 14. The term "MARKET/OFFER PRICE" shall mean
the greatest of (i) the price per share of Common Stock at which a tender offer
or exchange offer therefor has been made, (ii) the price per share of Common
Stock to be paid by any third party pursuant to an agreement with Issuer, (iii)
the highest closing price per share of Common Stock within the six-month period
immediately preceding the date on which the Holder gives notice of the required
repurchase of this Option or the Owner gives notice of the required repurchase
of Option Shares, as the case may be, and (iv) in the event of a sale of all or
a substantial portion of Issuer's assets, the sum of the price paid in such sale
for such assets and the current market value of the remaining assets of Issuer
as determined by a nationally recognized investment banking firm mutually
selected by the Holder or the Owner, as the case may be, on the one hand, and
the Issuer, on the other, divided by the number of shares of Common Stock of
Issuer outstanding at the time of such sale. In determining the Market/Offer
Price, the value of consideration other than cash shall be determined by a
nationally recognized investment banking firm mutually selected by the Holder or
Owner, as the case may be, on the one hand, and the Issuer, on the other.

    (b) Following a Repurchase Event, the Holder or the Owner, as the case may
be, may exercise its right to require Issuer to repurchase the Option and any
Option Shares pursuant to this Section 7 by surrendering for such purpose to
Issuer, at its principal office, a copy of this Agreement or certificates for
Option Shares, as applicable, accompanied by a written notice or notices stating
that the Holder or the Owner, as the case may be, elects to require Issuer to
repurchase this Option and/or the Option Shares, as the case may be, in
accordance with the provisions of this Section 7. Prior to the later of (x) the
date that is five business days after the surrender of the Option and/or
certificates representing Option Shares and the receipt of such notice or
notices relating thereto and (y) the day on which a Repurchase Event occurs,
Issuer shall deliver or cause to be delivered to the Holder the Option
Repurchase Price and/or to the Owner the Option Share Repurchase Price or the
portion thereof that Issuer is not then prohibited under applicable law and
regulation from so delivering.

    (c) To the extent that Issuer is prohibited under applicable law or
regulation from repurchasing the Option and/or the Option Shares in full, Issuer
shall immediately so notify the Holder and/or the Owner and thereafter shall
deliver or cause to be delivered, from time to time, to the Holder and/or the
Owner, as appropriate, that portion of the Option Repurchase Price and the
Option Share Repurchase Price, respectively, that it is no longer prohibited
from delivering, in each case within five business days after the date on which
Issuer is no longer so prohibited; PROVIDED, HOWEVER, that if Issuer at any time
after delivery of a notice of repurchase delivered by the Holder or the Owner
pursuant to paragraph (b) of this Section 7 is prohibited under applicable law
or regulation from delivering to the Holder and/or the Owner, as the case may
be, the Option Repurchase Price or the Option Share Repurchase Price,
respectively, in full, (and Issuer hereby undertakes to use its best efforts to
obtain all required regulatory and legal approvals and to file any required
notices as promptly as practicable in order to accomplish such repurchase), the
Holder or Owner may revoke its notice of repurchase of the Option or the Option
Shares either in whole or to the extent of the prohibition, whereupon, in the
latter case, Issuer shall promptly (i) deliver to the Holder and/or the Owner,
as appropriate, that portion of the Option Repurchase Price or the Option Share
Repurchase Price that Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Holder, a new Stock Option Agreement
evidencing the right of the Holder to purchase that number of shares of Common
Stock obtained by multiplying the number of shares of Common Stock for which the
surrendered Stock Option Agreement was exercisable at the time of delivery of
the notice of repurchase by a fraction, the numerator of which is the Option
Repurchase Price less the portion thereof theretofore delivered to the Holder
and the denominator of which is the Option Repurchase Price, or (B) to the
Owner, a certificate for the Option Shares it is then so prohibited from
repurchasing.

    (d) For purposes of this Section 7, a Repurchase Event shall mean and shall
be deemed to have occurred (i) upon the consummation of any merger,
consolidation or similar transaction involving

                                     B-1-7
<PAGE>
Issuer or any purchase, lease or other acquisition of all or a substantial
portion of the assets of Issuer, other than any such transaction which would not
constitute an Acquisition Transaction pursuant to the proviso to Section 2(c)(i)
hereof or (ii) upon the acquisition by any person of beneficial ownership of
more than 50% of the then outstanding shares of Common Stock; PROVIDED that no
such event shall constitute a Repurchase Event unless a Subsequent Triggering
Event shall have occurred prior to an Exercise Termination Event. The parties
hereto agree that Issuer's obligations to repurchase the Option or Option Shares
under this Section 7 shall not terminate upon the occurrence of an Exercise
Termination Event unless no Subsequent Triggering Event shall have occurred
prior to the occurrence of an Exercise Termination Event.

    8.  SUBSTITUTE OPTION.  (a) In the event that prior to an Exercise
Termination Event, Issuer shall enter into an agreement (i) to consolidate with
or merge into any person, other than Grantee or one of its Subsidiaries, and
shall not be the continuing or surviving corporation of such consolidation or
merger, (ii) to permit any person, other than Grantee or one of its
Subsidiaries, to merge into Issuer and Issuer shall be the continuing or
surviving corporation, but, in connection with such merger, the then outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other person or cash or any other property or the then
outstanding shares of Common Stock shall after such merger represent less than
50% of the outstanding voting shares and voting share equivalents of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Grantee or one of its Subsidiaries, then, and
in each such case, the agreement governing such transaction shall make proper
provision so that the Option shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, an option (the "SUBSTITUTE OPTION"), at the election of
the Holder, of either (x) the Acquiring Corporation (as defined below) or (y)
any person that controls the Acquiring Corporation.

    (b) The following terms have the meanings indicated:

        (1) "ACQUIRING CORPORATION" shall mean (i) the continuing or surviving
    corporation of a consolidation or merger with Issuer (if other than Issuer),
    (ii) Issuer in a merger in which Issuer is the continuing, surviving or
    acquiring person, and (iii) the transferee of all or substantially all of
    Issuer's assets.

        (2) "SUBSTITUTE COMMON STOCK" shall mean the common stock (or similar
    equity interest) issued by the issuer of the Substitute Option upon exercise
    of the Substitute Option.

        (3) "ASSIGNED VALUE" shall mean the Market/Offer Price, as defined in
    Section 7.

        (4) "AVERAGE PRICE" shall mean the average closing price of a share of
    the Substitute Common Stock for the one year immediately preceding the
    consolidation merger or sale in question but in no event higher than the
    closing price of the shares of Substitute Common Stock on the day preceding
    such consolidation, merger or sale; PROVIDED that if Issuer is the issuer of
    the Substitute Option, the Average Price shall be computed with respect to a
    share of common stock issued by the person merging into Issuer or by any
    company which controls or is controlled by such person, as the Holder may
    elect.

    (c) The Substitute Option shall have the same terms as the Option; PROVIDED
that if the terms of the Substitute Option cannot, for legal reasons, be the
same as the Option, such terms shall be as similar as possible to the terms of
the Option and in no event less advantageous to the Holder. The issuer of the
Substitute Option shall also enter into an agreement with the then Holder or
Holders of the Substitute Option in substantially the same form as this
Agreement, which shall be applicable to the Substitute Option.

    (d) The Substitute Option shall be exercisable for such number of shares of
Substitute Common Stock as is equal to the Assigned Value multiplied by the
number of shares of Common Stock for

                                     B-1-8
<PAGE>
which the Option is then exercisable, divided by the Average Price. The exercise
price of the Substitute Option per share of Substitute Common Stock shall then
be equal to the Option Price multiplied by a fraction, the numerator of which
shall be the number of shares of Common Stock for which the Option is then
exercisable and the denominator of which shall be the number of shares of
Substitute Common Stock for which the Substitute Option is exercisable.

    (e) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock outstanding prior to exercise of the Substitute Option. In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "SUBSTITUTE OPTION ISSUER")
shall make a cash payment to Holder equal to the excess of (i) the value of the
Substitute Option without giving effect to the limitation in this clause (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by the Holder or the
Owner, as the case may be.

    (f) Issuer shall not enter into any transaction described in subsection (a)
of this Section 8 unless the Acquiring Corporation and any person that controls
the Acquiring Corporation assume in writing all the obligations of Issuer
hereunder.

    9.  REPURCHASE OF SUBSTITUTE OPTION.  (a) At the request of the holder of
the Substitute Option (the "SUBSTITUTE OPTION HOLDER"), the Substitute Option
Issuer shall repurchase the Substitute Option from the Substitute Option Holder
at a price (the "SUBSTITUTE OPTION REPURCHASE PRICE") equal to the sum of the
amount by which (i) the Highest Closing Price (as defined below) exceeds (ii)
the exercise price of the Substitute Option, multiplied by the number of shares
of Substitute Common Stock for which the Substitute Option may then be exercised
(after giving effect to any limitations under the provisions of Section 14
hereof), and at the request of the Owner (the "SUBSTITUTE SHARE OWNER") of
shares of Substitute Common Stock (the "SUBSTITUTE SHARES"), the Substitute
Option Issuer shall repurchase the Substitute Shares at a price (the "Substitute
Share Repurchase Price") equal to the Highest Closing Price multiplied by the
number of Substitute Shares so designated. The term "HIGHEST CLOSING PRICE"
shall mean the highest closing price for shares of Substitute Common Stock
within the six month period immediately preceding the date the Substitute Option
Holder gives notice of the required repurchase of the Substitute Option or the
Substitute Share Owner gives notice of the required repurchase or the Substitute
Shares, as applicable.

    (b) The Substitute Option Holder or the Substitute Share Owner, as the case
may be, may exercise its respective right to require the Substitute Option
Issuer to repurchase the Substitute Option or the Substitute Shares, as the case
may be, pursuant to this Section 9 by surrendering for such purpose to the
Substitute Option Issuer, at its principal executive office, the agreement for
such Substitute Option (or, in the absence of such an agreement, a copy of this
Agreement) and certificates for Substitute Shares accompanied by a written
notice or notices stating that the Substitute Option Holder or the Substitute
Share Owner, as case may be, elects to require the Substitute Option Issuer to
repurchase the Substitute Option and/or the Substitute Shares, as the case may
be, in accordance with the provisions of this Section 9. As promptly as
practicable, and in any event within five business days after the surrender of
the Substitute Option and/or certificates representing Substitute Shares and the
receipt of such notice or notices delivered pursuant to this subsection (b) of
this Section 9 relating thereto, the Substitute Option Issuer shall deliver or
cause to be delivered to the Substitute Option Holder the Substitute Option
Repurchase Price and/or to the Substitute Share Owner the Substitute Share
Repurchase Price or, in either case, the portion thereof which the Substitute
Option Issuer is not then prohibited under applicable law and regulation from so
delivering.

    (c) To the extent that the Substitute Option Issuer is prohibited under
applicable law or regulation from repurchasing the Substitute Option and/or the
Substitute Shares in part or in fully, the

                                     B-1-9
<PAGE>
Substitute Option Issuer, following a request for repurchase pursuant to this
Section 9, shall immediately so notify the Substitute Option Holder and/or the
Substitute Share Owner and shall thereafter deliver or cause to be delivered,
from time to time, to the Substitute Option Holder and/or the Substitute Share
Owner, as appropriate, that portion of the Substitute Share Repurchase Price,
respectively, which it is no longer prohibited from delivering, in each case,
within five business days after the date on which the Substitute Option Issuer
is no longer so prohibited; PROVIDED, HOWEVER, that if the Substitute Option
Issuer at any time after delivery of a notice of repurchase delivered by the
Substitute Share Owner or Substitute Option Holder pursuant to subsection (b) of
this Section 9 is prohibited under applicable law or regulation from delivering
to the Substitute Option Holder and/or the Substitute Share Owner, as
appropriate, the Substitute Option Repurchase Price and the Substitute Share
Repurchase Price, respectively, in full (and the Substitute Option Issuer shall
use its best efforts to receive all required regulatory and legal approvals as
promptly as practicable in order to accomplish such repurchase), the Substitute
Option Holder or Substitute Share Owner may revoke its notice of repurchase of
the Substitute Option or the Substitute Shares either in whole or to the extent
of the prohibition, whereupon, in the latter case, the Substitute Option Issuer
shall promptly (i) deliver to the Substitute Option Holder or Substitute Share
Owner, as appropriate, that portion of the Substitute Option Repurchase Price or
the Substitute Share Repurchase Price that the Substitute Option Issuer is not
prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the
Substitute Option Holder, a new Substitute Option evidencing the right of the
Substitute Option Holder to purchase that number of shares of the Substitute
Common Stock obtained by multiplying the number of shares of the Substitute
Common Stock for which the surrendered Substitute Option was exercisable at the
time of delivery of the notice of repurchase by a fraction, the numerator of
which is the Substitute Option Repurchase Price less the portion thereof
theretofore delivered to the Substitute Option Holder and the denominator of
which is the Substitute Option Repurchase Price, or (B) to the Substitute Share
Owner, a certificate for the Substitute Common Shares it is then so prohibited
from repurchasing.

    10.  EXTENSION.  The period for exercise of certain rights under Sections 2,
6, 7, 9 and 13 shall be extended: (i) to the extent necessary to obtain all
regulatory approvals for the exercise of such rights, and for the expiration of
all statutory waiting periods; (ii) during any period for which an injunction or
similar legal prohibition on exercise shall be in effect; and (iii) to the
extent necessary to avoid liability under section 16(b) of the Exchange Act by
reason of such exercise.

    11.  REPRESENTATIONS AND WARRANTIES OF ISSUER.  Issuer hereby represents and
warrants to Grantee as follows:

        (a) Issuer has full corporate power and authority to execute and deliver
    this Agreement and to consummate the transactions contemplated hereby. The
    execution and delivery of this Agreement and the consummation of the
    transactions contemplated hereby have been duly and validly authorized by
    the Board of Directors of Issuer and no other corporate proceedings on the
    part of Issuer are necessary to authorize this Agreement or to consummate
    the transactions so contemplated. This Agreement has been duly and validly
    executed and delivered by Issuer.

        (b) Issuer has taken all necessary corporate action to authorize and
    reserve and to permit it to issue, and at all times from the date hereof
    through the termination of this Agreement in accordance with its terms will
    have reserved for issuance upon the exercise of the Option, that number of
    shares of Common Stock equal to the maximum number of shares of Common Stock
    at any time and from time to time issuable hereunder, and all such shares,
    upon issuance pursuant hereto, will be duly authorized, validly issued,
    fully paid, nonassessable, and will be delivered free and clear of al
    claims, liens, encumbrances and security interests and will not be subject
    to any preemptive rights.

        (c) The execution, delivery and performance of this Agreement does not
    or will not, and the consummation by Issuer of any of the transactions
    contemplated hereby will not, constitute or

                                     B-1-10
<PAGE>
    result in (i) a breach or violation of or a default under, its articles or
    certificate of incorporation or by-laws, or the comparable governing
    instruments of any of its subsidiaries, or (ii) a breach or violation of or
    a default under, any agreement, lease, contract, note, mortgage, indenture,
    arrangement or other obligation of it or any of its subsidiaries (with or
    without the giving of notice, the lapse of time or both) or under any law,
    rule, ordinance or regulation or judgment, decree, order, award or
    governmental or non-governmental permit or license to which it or any of its
    subsidiaries is subject.

        (d) No "fair price", "moratorium", "control share acquisition" or other
    similar anti-takeover statute or regulation enacted under state or federal
    laws applicable to the Issuer or any of its Subsidiaries is applicable to
    this Agreement or any of the transactions contemplated hereby. The action of
    the Board of Directors of the Issuer in approving this Agreement and the
    transactions contemplated hereby are sufficient to render inapplicable to
    this Agreement and the transactions contemplated hereby the restrictions on
    "business combinations" (as defined in Section 203 of the General
    Corporation Law of the State of Delaware) set forth in the General
    Corporation Law of the State of Delaware.

    12.  REPRESENTATIONS AND WARRANTIES OF GRANTEE.  Grantee hereby represents
and warrants to Issuer that:

        (a) Grantee has all requisite corporate power and authority to enter
    into this Agreement and, subject to any approvals or consents referred to
    herein, to consummate the transactions contemplated hereby. The execution
    and delivery of this Agreement and the consummation of the transactions
    contemplated hereby have been duly authorized by all necessary corporate
    action on the part of Grantee. This Agreement has been duly executed and
    delivered by Grantee.

        (b) The Option is not being, and any shares of Common Stock or other
    securities acquired by Grantee upon exercise of the option will not be,
    acquired with a view to the public distribution thereof and will not be
    transferred or otherwise disposed of except in conformance with this
    Agreement and in a transaction registered or exempt from registration under
    the Securities Act.

    13.  ASSIGNMENT.  Neither of the parties hereto may assign any of its rights
or obligations under this Agreement or the option created hereunder to any other
person, without the express written consent of the other party, except that
Grantee may assign in whole or in part the Option created hereunder and its
rights and obligations under this Agreement to CNET and, except that in any
event a Triggering Event shall have occurred prior to an Exercise Termination
Event, Grantee, subject to the express provisions hereof, may assign in whole or
in part its rights and obligations hereunder within 12 months following such
Triggering Event (or such later period as provided in Section 10).

    14.  TOTAL PROFIT  (a) Notwithstanding any other provision of this
Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined)
exceed $56,707,803, and if it otherwise would exceed such amount, the Grantee,
at its sole election, shall either (i) reduce the number of shares of Common
Stock subject to this Option, (ii) deliver to Issuer for cancellation Option
Shares previously purchased by Grantee, (iii) pay cash to Issuer, or (iv) any
combination thereof, so that Grantee's actually realized Total Profit shall not
exceed such amount after taking into account the foregoing actions.

    (b) Notwithstanding any other provision of this Agreement, this Option may
not be exercised for a number of shares as would, as of the date of exercise,
result in a Notional Total Profit (as defined below) of more than $56,707,803;
PROVIDED that nothing in this sentence shall restrict any exercise of the Option
permitted hereby on any subsequent date.

    (c) As used herein, the term "TOTAL PROFIT" shall mean the aggregate amount
(before taxes) of the following (without duplication): (i) the amount received
by Grantee pursuant to Issuer's repurchase of the Option (or any portion
thereof) pursuant to Section 7, (ii) (x) the amount received by Grantee pursuant
to Issuer's repurchase of Option Shares pursuant to Section 7, less (y) the
Grantee's purchase

                                     B-1-11
<PAGE>
price for such Option Shares, (iii) (x) the net cash amounts received by Grantee
pursuant to the sale of Option Shares (or any other securities into which such
Option Shares are converted or exchanged) to any unaffiliated party, less (y)
the Grantee's purchase price of such Option Shares, (iv) any amounts received by
Grantee on the transfer of the Option (or any portion thereof) to any
unaffiliated party, and (v) any amount equivalent to the foregoing with respect
to the Substitute Option.

    (d) As used herein and subject to Section 14(a), the term "NOTIONAL TOTAL
PROFIT" with respect to any number of shares as to which Grantee may propose to
exercise this option shall be the Total Profit determined as of the date of such
proposed exercise assuming that this Option were exercised on such date for such
number of shares and assuming that such shares, together with all other Option
Shares held by Grantee and its affiliates as of such date, were sold for cash at
the closing market price for the Common Stock as of the close of business on the
preceding trading day (less customary brokerage commissions).

    15.  RIGHT OF FIRST REFUSAL.  If, within 12 months immediately following the
first purchase of shares of Common Stock pursuant to the Option, Grantee shall
desire to sell, assign, transfer or otherwise dispose of all or any of the
Option or the shares of Common Stock or other securities acquired by it pursuant
to the Option, it shall give Issuer written notice of its intent to sell (an
"Offeror's Notice") specifying the securities to be sold, the price and the
material terms of any agreement relating thereto. An Offeror's Notice may be
given at any time. An Offeror's Notice shall be deemed an offer by Grantee to
Issuer, which may be accepted within 10 business days of the receipt by Issuer
of such Offeror's Notice, on the same terms and conditions and at the same price
at which Grantee is proposing to transfer the Option or such shares or other
securities. If Issuer (or one of its affiliates) exercises its right of first
refusal, the closing of the purchase of the Option or any such shares or other
securities by Issuer (or one of its affiliates) shall take place within 5
business days after the notice of such exercise and the purchase price shall be
paid to Grantee in immediately available funds; PROVIDED that at any time prior
to the closing of the purchase of the Option or any shares or other securities
hereunder, Grantee may determine not to sell the Option or such shares or other
securities and revoke the Offeror's Notice and, by so doing, cancel Issuer's
right of first refusal with respect thereto. If prior notification to or
approval of any regulatory authority is required in connection with such
purchase, Issuer shall promptly file the required notice or application for
approval and shall expeditiously process the same (and Grantee shall cooperate
with Issuer in the filing of any such notice or application and the obtaining of
any such approval) and the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which, as the case may be, (a)
the required notification period has expired or been terminated or (b) such
approval has been obtained and, in either event, any requisite waiting period
shall have passed. In the event of a failure or refusal of Issuer to purchase
all of the Option or all of the shares or other securities covered by an
Offeror's Notice or if any regulatory authority disapproves Issuer's proposed
purchase of any portion of the Option or such shares or other securities,
Grantee may, within 60 days from the date of the Offeror's Notice (subject to
any necessary extension for regulatory notification, approval or waiting
periods), sell or enter into an agreement to sell all, but not less than all, of
such portion of the Option or such shares or other securities at no less than
the price specified in the Offeror's Notice and on terms no more favorable than
those set forth in the Offeror's Notice. The requirements of this Section 16
shall not apply to (a) any disposition under Rule 144 or any other disposition
as a result of which a transferee would beneficially own not more than 4.9% of
the outstanding voting power of Issuer, (b) any disposition of Common Stock or
other securities by a person to whom Grantee has assigned its rights under the
Option with the consent of Issuer, (c) any sale by means of a public offering
registered under the 1933 Act, (d) any transfer to a wholly-owned subsidiary of
Grantee which agrees in writing to be bound by the terms hereof or (e) any
transfer in a tender offer or exchange offer or by operation of law upon
consummation of a merger or consolidation.

                                     B-1-12
<PAGE>
    16.  BEST EFFORTS.  Each of Grantee and Issuer will use its best efforts to
make all filings with, and to obtain consents of, all third parties and
governmental authorities necessary for the consummation of the transactions
contemplated by this Agreement, including without limitation making application
for quotation on the Nasdaq National Market (or, in the case of any Substitute
Shares, for listing or quotation on the principal exchange or quotation system
on which they trade) of the shares issuable hereunder upon official notice of
issuance.

    17.  SPECIFIC PERFORMANCE.  The parties hereto acknowledge that damages
would be an inadequate remedy for a breach of this Agreement by either party
hereto and that the obligations of the parties hereto shall be enforceable by
either party hereto through injunctive or other equitable relief.

    18.  SEVERABILITY.  If any term, provision, covenant or restriction
contained in this Agreement is held by a court or a federal or state regulatory
agency of competent jurisdiction to be invalid, void or unenforceable, the
remainder of the terms, provisions and covenants and restrictions contained in
this Agreement shall remain in full force and effect, and shall in no way be
affected, impaired or invalidated. If for any reason such court or regulatory
agency determines that the Holder is not permitted to acquire, or Issuer is not
permitted to repurchase pursuant to Section 7, the full number of shares of
Common Stock provided in Section 1(a) hereof (as adjusted pursuant to Section
1(b) or 5 hereof), it is the express intention of Issuer to allow the Holder to
acquire or to require Issuer to repurchase such lesser number of shares as may
be permissible, without any amendment or modification hereof.

    19.  NOTICES.  All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by cable, telegram, telecopy or telex, or by registered or certified
mail (postage prepaid, return receipt requested) at the respective addresses of
the parties set forth in the NMC Merger Agreement or such other address as shall
be provided in writing.

    20.  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without regard to conflicts of
laws principles thereof.

    21.  COUNTERPARTS.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same agreement.

    22.  EXPENSES.  Except as otherwise expressly provided herein, each of the
parties hereto shall bear and pay all costs and expenses incurred by it or on
its behalf in connection with the transactions contemplated hereunder, including
fees and expenses of its own financial consultants, investment bankers,
accountants and counsel.

    23.  ENTIRE AGREEMENT.  Except as otherwise expressly provided herein or in
the Merger Agreements, this Agreement contains the entire agreement between the
parties with respect to the transactions contemplated hereunder and supersedes
all prior arrangements or understandings with respect thereof, written or oral.
The terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective successors and permitted
assigns. Nothing in this Agreement, expressed or implied, is intended to confer
upon any party, other than the parties hereto, and their respective successors
and assigns, any rights, remedies, obligations or liabilities under or by reason
of this Agreement, except as expressly provided herein.

    24.  CAPTIONS; CAPITALIZED TERMS.  The section and paragraph captions herein
are for convenience of reference only, do not constitute part of this Agreement
and shall not be deemed to limit or otherwise affect any of the provisions
hereof. Capitalized terms used in this Agreement and not defined herein shall
have the meanings assigned thereto in the Merger Agreements.

and warrants to NBC and CNET as follows:

        (a)  POWER; BINDING AGREEMENT.  The Company has full power and authority
    to enter into and perform all of its obligations under this Agreement. The

<PAGE>
    agreement of the Company, enforceable against the Company in accordance with
    its terms, except as such enforceability may be limited by bankruptcy,
    insolvency, reorganization, moratorium and similar laws relating to or
    affecting creditors generally, by general equity principles (regardless of
    whether such enforceability is considered in a proceeding in equity or at
    law) or by an implied covenant of good faith and fair dealing.

        (b)  NO CONFLICTS.  No filing with, and no permit, authorization,
    consent or approval of, any state or federal governmental body or authority

    Agreement by the Company and the consummation by the Company of the

    authorization, consent or approval the failure of which to obtain would not
    reasonably be expected to prevent the Company from performing its respective
    obligations under this Agreement, and neither the execution and delivery of
    this Agreement by the Company nor the consummation by the Company of the

    a violation or breach of, or constitute (with or without notice or lapse of
    time or both) a default (or give rise to any third-party right of
    termination, cancellation, material modification or acceleration) under any

        (a)  OWNERSHIP OF SECURITIES.  Each Holder is the record and beneficial
    owner of, and has good and marketable title to, the number of shares of
    Company Common Stock (the "Existing Securities") (together with any shares
    of Company Common Stock hereafter acquired by any Holder (including through
    the exercise of options or similar instruments) the "Subject Securities")
    set forth on Exhibit A to this Agreement, attached hereto and incorporated

    of the transactions contemplated hereby, have been duly and validly
    authorized by all necessary corporate action of each of the Holders. This
    Agreement has been duly and validly executed and delivered by each Holder
    and constitutes a valid and binding agreement of such Holder, enforceable
    against such Holder in accordance with its terms, except as such
    enforceability may be limited by bankruptcy, insolvency, reorganization,
    moratorium and similar laws relating to or affecting creditors generally, by
    general equity principles (regardless of whether such enforceability is
    considered in a proceeding in equity or at law) or by an implied covenant of
    good faith and fair dealing.

    consent or approval of, any state or federal governmental body or authority

    Agreement by any Holder and the consummation by such Holder of the
    transactions contemplated hereby, other than pursuant to the Exchange Act,
    the HSR Act or foreign competition or antitrust laws or any filing, permit,
    authorization, consent or approval, the failure of which to obtain would not

    applicable organizational documents or instruments applicable to such
    Holder, result in a violation or breach of, or constitute (with or without
    notice or lapse of time or both) a default (or give rise to any third-party
    right of termination, cancellation, material modification or acceleration)
    under any of the terms, conditions or provisions of any note, bond,
    mortgage, indenture, license, contract, commitment, arrangement,
    understanding, agreement or other instrument or obligation of any kind to
    which such Holder is a party or by which such Holder's Subject Securities
    may be bound or violate any order, writ, injunction, decree, judgment,
    statute, rule or regulation applicable to such Holder as of the date hereof,
    other than such violations, breaches or defaults that would not reasonably
    be expected to prevent such Holder from performing its obligations under
    this Agreement.

        (d)  NO LIENS.  The Existing Securities are now and, at all times during
    the term hereof, the Subject Securities will be held by such Holder, or by a
    nominee or custodian for the benefit of such Holder, free and clear of all
    liens, claims, security interests, proxies, voting trusts or agreements,
    understandings or arrangements or any other encumbrances whatsoever, except
    for any encumbrances arising hereunder.

    3.  AGREEMENT TO VOTE SHARES.  At every meeting of the stockholders of the
Company called with respect to any of the following, and at every adjournment
thereof, and on every action or approval by written consent of the stockholders
of the Company with respect to any of the following, each Holder irrevocably
agrees that it shall vote (or cause to be voted) all of the Subject Securities
that it beneficially owns on the record date of any such vote or action (a) in
favor of the adoption of the Merger Agreements and the approval of the terms
thereof (with such modifications as the parties thereto may make (except for
modifications that would adversely affect such Holder)) and each of the other
transactions contemplated by the Merger Agreements and (b) against any of the
following (or any agreement to enter into or effect any of the following): (i)
prior to the Effective Time, any Takeover Proposal, Material Transaction
Proposal requiring the vote of the Company's stockholders or transaction or
occurrence which if publicly proposed and offered to the Company and its
stockholders (or any of them) would be the subject of a Takeover Proposal or
Material Transaction Proposal, or (ii) any amendment of the Company's
certificate of incorporation or by-laws or other proposal, action or transaction
involving the Company 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 Merger
Agreements. Such Holder shall not commit or agree to take any action
inconsistent with the foregoing.

    4.  IRREVOCABLE PROXY.  Each Holder hereby, severally and not jointly,
grants to, and appoints 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 hereafter succeed to any such office of 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 Subject Securities in accordance with
Section 3 hereof. This proxy is coupled with an interest and shall be
irrevocable, and each Holder will take such further action or execute such other
instruments as may be necessary to effectuate the intent of this proxy and
hereby revokes any proxy previously granted by it with respect to

                                     B-2-3
<PAGE>
the Subject Securities; provided that this proxy shall be automatically revoked
without any further action on the part of the Holder, NBC and CNET upon the
termination of this Agreement pursuant to Section 16 hereof.

    5.  REPRESENTATIONS AND WARRANTIES OF NBC AND CNET.  Each of NBC and CNET
represents and warrants, severally and not jointly (and only as to itself), to
the Company and each Holder as follows:

        (a)  POWER; BINDING AGREEMENT.  Each of NBC and CNET has full power and
    authority to enter into and perform all of its obligations under this
    Agreement. The execution, delivery and performance of this Agreement, and
    the consummation of the transactions contemplated hereby, have been duly and
    validly authorized by all necessary corporate action of NBC and CNET. This
    Agreement has been duly and validly executed and delivered by each of NBC
    and CNET and constitutes a valid and binding agreement of each of NBC and
    CNET, enforceable against each of NBC and CNET in accordance with its terms,
    except as such enforceability may be limited by bankruptcy, insolvency,
    reorganization, moratorium and similar laws relating to or affecting
    creditors generally, by general equity principles (regardless of whether
    such enforceability is considered in a proceeding in equity or at law) or by
    an implied covenant of good faith and fair dealing.

        (b)  NO CONFLICTS.  No filing with, and no permit, authorization,
    consent or approval of, any state or federal governmental body or authority
    or any other person or entity is necessary for the execution of this
    Agreement by NBC or CNET and the consummation by NBC or CNET of the
    transactions contemplated hereby, other than pursuant to the Exchange Act,
    the HSR Act or foreign competition or antitrust laws or any filing, permit,
    authorization, consent or approval, the failure of which to obtain would not
    reasonably be expected to prevent NBC or CNET from performing its respective
    obligations under this Agreement, and neither the execution and delivery of
    this Agreement by NBC or CNET nor the consummation by NBC or CNET of the
    transactions contemplated hereby nor compliance by NBC or CNET with any of
    the provisions hereof will conflict with or result in any breach of any
    organizational documents or instruments applicable to NBC or CNET,
    respectively, result in a violation or breach of, or constitute (with or
    without notice or lapse of time or both) a default (or give rise to any
    third-party right of termination, cancellation, material modification or
    acceleration) under any of the terms, conditions or provisions of any note,
    bond, mortgage, indenture, license, contract, commitment, arrangement,
    understanding, agreement or other instrument or obligation of any kind to
    which NBC or CNET is a party or by which NBC or CNET's respective properties
    or assets may be bound or violate any order, writ, injunction, decree,
    judgment, statute, rule or regulation applicable to NBC or CNET as of the
    date hereof, other than such violations, breaches or defaults that would not
    reasonably be expected to prevent NBC or CNET from performing its respective
    obligations under this Agreement.

    6.  COVENANT OF THE COMPANY.  The Company hereby agrees and covenants that
it shall not, and shall direct its transfer agent not to, transfer any Company
Common Stock except in accordance with the provisions of Section 7(b) hereof.

    7.  COVENANTS OF THE HOLDERS.  Each Holder hereby agrees and covenants that:

        (a)  NO SOLICITATION.  Each Holder shall not, and shall not authorize
    and shall use his reasonable best efforts not to permit any of his, her or
    its affiliates, partners, investment bankers, attorneys, agents or other
    advisors or representatives to, directly or indirectly, solicit, knowingly
    encourage (including by way of providing confidential information or data)
    or have any discussion or negotiate with any person or entity (other than
    NBC, CNET or any affiliate of NBC or CNET) concerning any proposal by such
    person or entity with respect to the Company that constitutes or could
    reasonably be expected to lead to a Takeover Proposal or Material
    Transaction Proposal. Each Holder will immediately cease and cause to be
    terminated any existing activities, discussions

                                     B-2-4
<PAGE>
    or negotiations with any parties conducted heretofore by or on its behalf
    with respect to any of the foregoing.

        (b)  RESTRICTION ON TRANSFER, PROXIES AND NONINTERFERENCE.  Each Holder
    shall not, and shall not authorize or permit any of his, her or its
    affiliates, partners, investment bankers, attorneys, agents or other
    advisors or representatives to, directly or indirectly: (i) offer for sale,
    sell, transfer, tender, pledge, encumber, assign or otherwise dispose of
    (including by gift), or enter into any contract, option or other arrangement
    or understanding with respect to or consent to the offer for sale, sale,
    transfer, tender, pledge, encumbrance, assignment or other disposition of,
    any or all of the Subject Securities (or any interest therein), unless the
    transferee or pledgee of such Subject Securities agrees in writing in a form
    reasonably satisfactory to NBC (with a copy furnished to NBC and CNET) to be
    bound by all of the provisions of this Agreement with respect to such
    transferred or pledged Subject Securities, as contemplated by the NMC Merger
    Agreement; (ii) except as contemplated hereby, grant any proxies or powers
    of attorney, deposit any such Subject Securities into a voting trust or
    enter into a voting agreement with respect to any of the Subject Securities;
    (iii) take any action that would have the effect of preventing or disabling
    such Holder from performing his obligations under this Agreement; or (iv)
    commit or agree to take any of the foregoing actions.

        (c) Each Holder agrees to submit to the Company contemporaneously with
    or promptly following execution of this Agreement all certificates
    representing the Company Common Stock so that the Company may note thereon a
    conspicuous legend referring to the transfer restrictions set forth in this
    Agreement.

        (d) Each Holder will, from time to time, execute and deliver, or cause
    to be executed and delivered, such additional or further consents, documents
    and other instruments as NBC may reasonably request for the purpose of
    effectuating the matters covered by this Agreement.

    8.  FIDUCIARY DUTIES.  Notwithstanding anything in this Agreement to the
contrary, the covenants and agreements set forth in Section 7(a) shall not
prevent any Holder from taking any action, subject to the applicable provisions
of the NMC Merger Agreement, while acting as a director of the Company. NBC and
CNET acknowledge and agree that each Holder who has signed this Agreement does
so solely in his capacity as a stockholder of the Company, and not in his
capacity as a director, officer or employee of the Company, and that such action
on behalf of such Holder does not limit or restrict his ability to vote, or
otherwise act, in his capacity as a director, officer or employee of the
Company. Notwithstanding the foregoing, except as contemplated by Section 16
hereof, this Agreement shall be and shall remain binding upon such Holder
irrespective of any action taken by any such Holder in his capacity as a
director, officer or employee of the Company.

    9.  ASSIGNMENT; BENEFITS.  This Agreement may not be assigned by any party
hereto without the prior written consent of the other party. Subject to the
preceding sentence, this Agreement shall be binding upon, and shall inure to the
benefit of, each of the Holders, NBC, CNET and their respective successors and
permitted assigns.

    10.  NOTICES.  All notices and other communications given or made pursuant
hereto shall be in writing and shall be deemed to have been duly given or made

                                     B-2-7

The Board of Directors
Xoom.com, Inc.
300 Montgomery Street, Suite 300
San Francisco, CA 94104

Attention:  Christopher A. Kitze
        Chairman & Co-Founder

Gentlemen:

    We understand that Xoom.com, Inc. ("Xoom") proposes to enter into an
Agreement and Plan of Contribution and Merger (the "Merger Agreement") among
Xoom, National Broadcasting Company, Inc. and certain of its affiliates
(collectively, "NBC"), CNET, Inc. ("CNET") and SNAP! LLC, an Agreement and Plan
of Contribution, Investment and Merger (the "Contribution Agreement") among NBC,
GE Investments Sub, Inc., Neon Media Corporation, Xenon 2, Inc. and Xoom, as
well as a series of other agreements (collectively with the Merger Agreement and
the Contribution Agreement, the "Agreements") relating to the formation of a new
company to be named NBC Internet, Inc. ("NBCi"). NBCi is expected to include the
businesses of Xoom, SNAP! LLC and certain of NBC's internet assets, including
NBC.com, Videoseeker.com, NBC Interactive Neighborhood and a 10% ownership
interest in CNBC.com (collectively, the "NBC Contributed Internet Assets").

    The first transaction will be effected by a merger of Xoom with Xenon 3,
Inc., a subsidiary of NBCi, followed by NBCi acquiring CNET's ownership interest
in SNAP! LLC (the "CNET Contributed Assets"). In a subsequent transaction, Neon
Media Corporation ("NMC"), a newly formed entity which will own the NBC
Contributed Internet Assets, is expected to be merged with NBCi, and NBC's
ownership interests in SNAP! LLC are expected to be contributed to NBCi. In
connection with the consummation of all of the transactions contemplated by the
Agreements, the following would occur on successive days:

    Initially, (i) each share of Xoom common stock will be converted into the
right to receive one share of NBCi Class A comon stock and (ii) CNET will
receive 7,147,584 shares of Class A common stock of NBCi in exchange for its
ownership interest in SNAP! LLC (collectively with step (i) above, the "CNET
Transaction"). On the succeeding day, (A) each share of NMC common stock will be
exchanged for one share of Class B common stock of NBCi, which will result in
the issuance of 13,764,726 shares of Class B common stock and (B) a subsidiary
of NBC will receive 11,417,569 shares of Class B common stock of NBCi in
exchange for its ownership interests in SNAP! LLC (including its options to
purchase additional equity interests) (collectively with step (A) above, the
"NBC Share Issuance").

    Thereafter, an affiliate of NBC will purchase a $486,894,758 zero coupon
convertible debenture due 2006 (the "Convertible Note") of NBCi for a cash
payment of $30 million and the assignment of an NBC promissory note in the
amount of $340 million to NBCi (collectively with the NBC Share Issuance, the
"NBC Transaction"). The CNET Transaction and the NBC Transaction are
collectively referred to as the "Transactions."

    Only the Class A common stock of NBCi will be publicly traded. Separate
agreements are being entered into with respect to the transactions set forth in
clauses (i) and (ii) and with respect to the

                                     C-1-1
<PAGE>
The Board of Directors
Xoom.com, Inc.

Page 2

transactions set forth in clauses (A) and (B). The closing of the transactions
set forth in clauses (i) and (ii) will occur first and will not be contingent
upon the closing of the NBC Transaction.

    We further understand that assuming both transactions were consummated on
the date of this opinion, NBC and its affiliates would own approximately 49.9%
of NBCi voting securities, Xoom's former stockholders and option holders would
own approximately 36% of NBCi voting securities and CNET would own approximately
14% of NBCi voting securities. If NBC chooses to convert the Convertible Note
after one year, NBC, through its affiliates, could own approximately 53% of the
currently expected fully-diluted equity of NBCi.

    You have asked us to render our opinion as to whether, after issuance of
NBCi shares to Xoom stockholders in the merger of Xenon 3, Inc. with Xoom (i)
the aggregate issuance of NBCi shares to NBC and CNET in the transactions
contemplated by the Merger Agreement and the Contribution Agreement, taken
together (both before and after conversion of the NBCi convertible notes), in
exchange for the aggregate contribution of SNAP! LLC and the NBC Contributed
Internet Assets and (ii) the issuance of NBCi shares to CNET in the transactions
contemplated by the Merger Agreement, if the transactions contemplated by the
Contribution Agreement are not consummated, in exchange for CNET's contribution
of its equity interests in SNAP! LLC, are fair, from a financial point of view,
to Xoom and its stockholders.

    In the course of our analyses for rendering this opinion, we have:

      1. reviewed draft forms of the Merger Agreement, the Contribution
         Agreement, the other Agreements (each draft dated May 6, 1999) and
         certain other documents relating to the proposed Transactions;

      2. reviewed Xoom's Annual Report to Shareholders and Annual Report on Form
         10-K for the fiscal year ended December 31, 1998;

      3. reviewed certain operating and financial information, including
         projections, provided to us by management relating to Xoom's business
         and prospects;

      4. met with certain members of Xoom's senior management to discuss its
         operations, historical financial statements and future prospects;

      5. reviewed the historical prices and trading volume of the common shares
         of Xoom;

      6. reviewed the trading activity of various Internet companies, including
         those which we deemed generally comparable to Xoom;

      7. reviewed certain operating and financial information, including
         projections, provided to us by management of Xoom relating to NBC's
         Internet assets and SNAP! LLC;

      8. met with certain members of the senior management of NBC to discuss the

      9. reviewed publicly available financial data, stock market performance
         data and valuation parameters of companies which we deemed generally

         effect to the proposed Transactions;

     10. reviewed the terms of recent acquisitions of companies which we deemed
         generally comparable to the proposed Transactions; and

     11. conducted such other studies, analyses, inquiries and investigations as
         we deemed appropriate.

    In the course of our review, we have relied on and assumed, without
independent verification, the accuracy and completeness of the financial and
other projections provided to us by Xoom and NBC. With respect to the projected
financial results provided to us, we have assumed that they have been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the senior managements of Xoom and NBC as to the expected future
performance of Xoom, the CNET Contributed Assets, the NBC Contributed Internet
Assets and SNAP! LLC. We have not assumed any responsibility for the independent
verification of any such information or of the projections provided to us and we
have further relied upon the assurances of the senior managements of Xoom and
NBC that they are unaware of any facts that would make the information or
projections provided to us incomplete or misleading. In arriving at our opinion,
we have not performed or obtained any independent appraisal of the assets or
liabilities of Xoom, or with respect to the CNET Contributed Assets, the NBC
Contributed Internet Assets and SNAP! LLC, nor have we been furnished with any
such appraisals. Our opinion is necessarily based on economic, market and other
conditions, and the information made available to us, as of the date hereof.
Furthermore, we recognize that the market prices for Internet related companies
such as Xoom have been the subject of significant speculation and movement in
recent months and this opinion is not intended to predict or otherwise guarantee
the trading prices of Xoom or NBCi following the announcement or consummation of
the Transactions, as the case may be.

    We have acted as a financial advisor to Xoom in connection with the
Transactions and will receive a fee for such services.

    In the ordinary course of business, Bear Stearns may actively trade the
equity securities of Xoom, CNET and General Electric (the publicly-traded parent
of NBC) for its own account and for the account of its customers and,
accordingly, may at any time, hold a long or short position in such securities.

    Upon Xoom and NBC entering into a non-solicitation and confidentiality
agreement on April 15, 1999, we were requested to prepare this opinion in
connection with the proposed transactions involving NBC and we were directed not
to, and we did not, seek or pursue alternative transactions to the Transactions,
including the possible sale of Xoom as an entirety. Although upon the
consummation of the Transactions, NBC and its subsidiaries will own only
approximately 48.5% of the common stock of NBCi, in our capacity as financial
advisor to Xoom, we conservatively assumed, consistent with Delaware law, solely
for purposes of rendering this fairness opinion, that this ownership interest
should be viewed as a change of control transaction for purposes of evaluating
whether, after issuance of NBCi shares to Xoom stockholders in the merger of
Xenon 3, Inc. with Xoom (i) the aggregate issuance of NBCi shares to NBC and
CNET in the transactions contemplated by the Merger Agreement and the
Contribution Agreement, taken together (both before and after conversion of the
NBCi convertible notes), in exchange for the aggregate contribution of SNAP! LLC
and the NBC Contributed Internet Assets and (ii) the issuance of NBCi shares to
CNET in the transactions contemplated by the Merger Agreement, if the
transactions contemplated by the Contribution Agreement are not consummated, in

exchange for CNET's contribution of its equity interests in SNAP! LLC, are fair,
from a financial point of view, to Xoom and its stockholders. In rendering this
opinion, we are not addressing whether and under what circumstances any third
party interest in Xoom may arise as a result of entering into the agreements
related to the Transactions. In addition, this opinion does not address or make
any assumptions with respect to the accounting treatment applicable to the
Transactions or to each of Xoom, CNET and NBC.

    It is understood that this letter is intended for the benefit and use of the
Board of Directors of Xoom and does not constitute a recommendation to the Board
of Directors or shareholders of Xoom. This opinion does not address Xoom's
underlying business decision to pursue the Transaction. This letter is not to be
used for any other purpose, or reproduced, disseminated, quoted to or referred
to at any time, in whole or in part, without our prior written consent.

    Based on and subject to the foregoing, it is our opinion that, after
issuance of NBCi shares to Xoom stockholders in the merger of Xenon 3, Inc. with
Xoom (i) the aggregate issuance of NBCi shares to NBC and CNET in the
transactions contemplated by the Merger Agreement and the Contribution
Agreement, taken together (both before and after conversion of the NBCi
convertible notes), in exchange for the aggregate contribution of SNAP! LLC and
the NBC Contributed Internet Assets and (ii) the issuance of NBCi shares to CNET
in the transactions contemplated by the Merger Agreement, if the transactions
contemplated by the Contribution Agreement are not consummated, in exchange for
CNET's contribution of its equity interests in SNAP! LLC, are fair, from a
financial point of view, to Xoom and its stockholders.

                                          Very truly yours,

                       HAMBRECHT & QUIST FAIRNESS OPINION

May 9, 1999
CONFIDENTIAL

The Board of Directors
XOOM.com, Inc.
300 Montgomery Street, 3(rd) Floor
San Francisco, CA 94104

Gentlemen:

    You have requested our opinion to the effect that, after issuance of NBC
Internet, Inc. ("NBCi") shares to XOOM.com, Inc. ("Xoom" or the "Company")
stockholders in the merger of Xenon 3, Inc. with Xoom, the aggregate issuance of
NBCi shares to NBC and CNET in the transactions (the "Proposed Transactions")
contemplated by the Merger Agreement (as defined herein) and the Contribution
Agreement (as defined herein and together with the Merger Agreement, the
"Agreements"), taken together (both before and after conversion of the NBCi
convertible notes), in exchange for the aggregate contribution of Snap! LLC and
the NBC contributed Internet businesses, was fair, from a financial point of
view to Xoom and its stockholders.

    We understand that the terms of the Agreements provide, among other things,
that each issued and outstanding share of Common Stock shall be converted into
the right to receive one share of common stock of Xenon 2, Inc., as more fully
set forth in the Agreements. For purposes of this opinion, we have assumed that
the Proposed Transactions will be implemented on a tax-free basis under the
United States Internal Revenue Code and that the Proposed Transactions will be
accounted for as a purchase.

    Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment
banking services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. We have acted as a financial advisor to the Board of
Directors of Xoom in connection with the Proposed Transactions solely for the
purpose of issuing this opinion, and we will receive a fee for our services.

    In the past, we have provided investment banking and other financial
advisory services to Xoom and have received fees for rendering these services.
In the ordinary course of business, Hambrecht & Quist acts as a market maker and
broker in the publicly traded securities of Xoom and CNET and receives customary
compensation in connection therewith, and also provides research coverage for
Xoom. In the ordinary course of business, Hambrecht & Quist actively trades in
the equity and derivative securities of Xoom and CNET for its own account and
for the accounts of its customers and, accordingly, may at any time hold a long
or short position in such securities. Hambrecht & Quist may in the future
provide additional investment banking or other financial advisory services to
Xoom, CNET or NBCi.

    In connection with our review of the Proposed Transactions, and in arriving
at our opinion, we have, among other things:

     (i) reviewed the financial statements of Snap! LLC and the NBC contributed
         businesses NBC.com, NBC-IN, VideoSeeker and CNBC.com (the "Contributed
         Businesses") for recent years and interim periods to date and certain
         other relevant financial and operating data of

       the Contributed Businesses made available to us from the internal records
         of the Contributed Businesses;

     (ii) reviewed certain internal financial and operating information,
          including certain projections, relating to the Contributed Businesses
          prepared by the management of Xoom;

    (iii) discussed the business, financial condition and prospects of the
          Contributed Businesses with certain members of senior management of
          the Contributed Businesses;

     (iv) reviewed the publicly available financial statements of Xoom for
          recent years and interim periods to date and certain other relevant
          financial and operating data of Xoom made available to us from
          published sources and from internal records of Xoom;

     (v) discussed the business, financial condition and prospects of Xoom with
         certain members of Xoom's senior management;

     (vi) reviewed the recent reported prices and trading activity for the
          common stock of Xoom and compared such information and certain
          financial information for Xoom and the Contributed Businesses with
          similar information for certain other companies engaged in businesses
          we consider generally comparable;

    (vii) reviewed the financial terms, to the extent publicly available, of
          certain comparable merger and acquisition transactions;

   (viii) reviewed the draft Agreement and Plan of Contribution and Merger dated
          as of May 6, 1999, among CNET, Inc., Xoom, Xenon 2, Inc., Xenon 3,
          Inc. and Snap! LLC, which agreement Hambrecht & Quist assumed was the
          same as the Agreement and Plan of Contribution and Merger dated May 9,
          1999 (the "Merger Agreement"), and the draft Agreement and Plan of
          Contribution, Investment and Merger, dated as of May 6, 1999, among
          National Broadcasting Company, Inc., GE Investments Subsidiary, Inc.,
          Neon Media Corporation, Xenon 2, Inc., and Xoom, which agreement
          Hambrecht & Quist assumed was the same as the Agreement and Plan of
          Contribution, Investment and Merger dated May 9, 1999 (the
          "Contribution Agreement") and certain other documents relating to the
          Proposed Transactions; and

     (ix) performed such other analyses and examinations and considered such
          other information, financial studies, analyses and investigations and
          financial, economic and market data as we deemed relevant.

    In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning the Contributed Businesses and
Xoom considered in connection with our review of the Proposed Transactions, and
we have not assumed any responsibility for independent verification of such
information. We have not prepared any independent valuation or appraisal of any
of the assets or liabilities of the Contributed Businesses or Xoom, nor have we
conducted a physical inspection of the properties and facilities of any of the
businesses. With respect to the financial forecasts and projections made
available to us and used in our analysis, we have assumed that they reflect the
best currently available estimates and judgments of the expected future
financial performance of the Contributed Businesses and Xoom. For purposes of
this opinion, we have assumed that neither the Contributed Businesses nor Xoom
is a party to any pending transactions, including external financings,
recapitalizations or material merger discussions, other than the Proposed
Transactions and those activities undertaken in the ordinary course of
conducting their respective

businesses. Our opinion is necessarily based upon market, economic, financial
and other conditions as they exist and can be evaluated as of the date of this
letter and any change in such conditions would require a reevaluation of this
opinion. We express no opinion as to the price at which Xenon 2, Inc. common
stock will trade subsequent to the Effective Time (as defined in the
Contribution Agreement). In rendering this opinion, we have assumed that the
Proposed Transactions will be consummated substantially on the terms discussed
in the Agreements, without any waiver of any material terms or conditions by any
party thereto. We were not requested to, and did not, solicit indications of
interest from any other parties in connection with a possible acquisition of, or
business combination with, Xoom.

    It is understood that this letter is for the information of the Board of
Directors and may not be used for any other purpose without our prior written
consent; provided, however, that this letter may be reproduced in full in the
Registration Statement on Form S-4 filed in connection with the Proposed
Transactions. This letter does not constitute a recommendation to any
stockholder as to how such stockholder should vote on the Proposed Transactions.

    Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that as of the date hereof,
after the issuance of NBCi shares to Xoom stockholders in the merger of Xenon 3,
Inc. with Xoom, the aggregate issuance of NBCi shares to NBC and CNET in the
transactions contemplated by the Merger Agreement and the Contribution Agreement
taken together (both before and after conversion of the NBCi convertible notes),
in exchange for the aggregate contribution of Snap! LLC and the NBC contributed
Internet businesses, are fair to Xoom and its stockholders from a financial
point of view. We express no opinion, however, as to the fairness or adequacy of
any consideration received in the Proposed Transactions by CNET, Inc. or
National Broadcasting Company, Inc. or any of their respective affiliates.

                                          Very truly yours,

    stock split, stock dividend, reverse stock split, combination or
    reclassification of the Common Stock, or any other similar event resulting
    in an increase or decrease in the number of outstanding shares of Common
    Stock, the outstanding shares of Class A Common Stock and the outstanding
    shares of Class B Common Stock shall be adjusted in the same manner in all
    respects.

        6.  DISSOLUTION.  In the event of any dissolution, liquidation or
    winding up of the affairs of the Corporation, whether voluntary or
    involuntary, after payment in full of the amounts required to be paid to the
    holders of Preferred Stock, the remaining assets and funds of the
    Corporation shall be distributed PRO RATA to the holders of Common Stock,
    and the holders of Class A Common Stock and the holders of Class B Common
    Stock will be entitled to receive the same amount per share in respect
    thereof.

        7.  MERGER.  Unless otherwise approved by a majority of the votes
    entitled to be cast by the holders of the outstanding shares of Class A
    Common Stock and the outstanding shares of Class B Common Stock, each voting
    separately as a class, in case of any reorganization or any consolidation of
    the Corporation with one or more other corporations or a merger of the
    Corporation with another corporation in which shares of Class A Common Stock
    or Class B Common Stock are converted into (or entitled to receive with
    respect thereto) shares of stock and/ or other securities or property
    (including cash), each holder of a share of Class A Common Stock shall be
    entitled to receive with respect to such share the same kind and amount of
    shares of stock and other securities and property (including cash)
    receivable upon such reorganization, consolidation or merger by a holder of
    a share of Class B Common Stock, and each holder of a share of Class B
    Common Stock shall be entitled to receive with respect to such share the
    same kind and amount of shares of stock and other securities and property
    (including cash) receivable upon such reorganization, consolidation or
    merger by a holder of a share of Class A Common Stock. In the event that the
    holders of Class A Common Stock or of Class B Common Stock are granted
    rights to elect to receive one of two or more alternative forms of
    consideration, the foregoing provision shall be deemed satisfied if holders
    of Class A Common Stock and holders of Class B Common Stock are granted
    substantially identical election rights; PROVIDED that notwithstanding
    anything contained in this paragraph 7 to the contrary, the Corporation may
    effect any reorganization, consolidation or merger, pursuant to which shares
    of Class A Common Stock and Class B Common Stock are converted into shares
    of two classes of capital stock having substantially the same relative
    rights as the Class A Common Stock and the Class B Common Stock, as set
    forth in this Restated Certificate of Incorporation, if it is approved by
    the holders of a majority of the outstanding shares of the Class A Common
    Stock and the Class B Common Stock voting together as a single class without
    any separate class vote.

        8.  NO ADVERSE EFFECT.  With respect to any proposed amendment of this
    Restated Certificate of Incorporation which would alter or change the
    powers, preferences or special rights of the shares of Class A Common Stock
    or Class B Common Stock, so as to affect them adversely, the approval of a
    majority of the votes entitled to be cast by the holders of the outstanding
    shares of the class affected by the proposed amendment, voting separately as
    a class, shall be obtained in addition to the approval of a majority of the
    votes entitled to be cast by the holders of the outstanding shares of Class
    A Common Stock and the Class B Common Stock voting together as a single
    class as provided herein. The affirmative vote of shares representing a
    majority of the votes entitled to be cast by the holders of outstanding
    shares of each class of Common Stock, voting separately by class, shall be
    required to adopt any provision inconsistent with or repeal any

                                     D-1-3
<PAGE>
    provision of, or alter or amend this paragraph 8. Subject to the rights of
    the holders of any series of Preferred Stock pursuant to the terms of this
    Restated Certificate of Incorporation or any resolutions providing for the
    issuance of such series of stock adopted by the Board of Directors, the
    number of authorized shares of Class A Common Stock, Class B Common Stock or
    Preferred Stock may be increased or decreased (but not below the number of
    shares thereof then outstanding) by the affirmative vote of the holders of a
    majority in voting power of the outstanding shares of capital stock of the
    Corporation entitled to vote generally in the election of directors
    irrespective of the provisions of Section 242(b)(2) of the General
    Corporation Law.

    9.  CONVERSION OF CLASS B COMMON STOCK.

           (a)  VOLUNTARY CONVERSION.  Upon the affirmative vote or written
       request of the holders of a majority of the outstanding shares of Class B
       Common Stock for the conversion of the Class B Common Stock into Class A
       Common Stock, all, but not less than all, of the outstanding shares of
       Class B Common Stock shall automatically convert on a share for share
       basis into the same number of shares of Class A Common Stock. In
       addition, the Corporation shall permit NBC Parent and its Affiliates, at
       such time as any such Person shall become a holder of Common Stock while
       shares of Class B Common Stock are outstanding, to convert shares of
       Class A Common Stock into shares of Class B Common Stock upon written
       request subject to the terms and conditions of the Governance and
       Investor Rights Agreement, dated as of           , 1999 between the
       Corporation and NBC, as amended from time to time (the "Governance
       Agreement"), a copy of which is maintained at the Corporation's principal
       office.

           (b)  MANDATORY CONVERSION.  Shares of Class B Common Stock shall be
       converted into shares of Class A Common Stock at the times and in the
       amounts set forth in subparagraphs (i) and (ii) of this subparagraph (b)
       (each an "Event of Conversion").

                (i) Upon any sale, pledge, conveyance, assignment, transfer or
           other disposition of shares of Class B Common Stock, whether or not
           for value, by NBC or any of its Affiliates, other than any transfer
           by such holder to an Affiliate of such holder, the shares of Class B
           Common Stock disposed of as above by NBC or such Affiliate shall
           automatically be converted into shares of Class A Common Stock on a
           share for share basis without further action by the holders of Common
           Stock; PROVIDED that a pledge of shares of Class B Common Stock,
           prior to default thereunder, which does not grant to the pledgee the
           power to vote or direct the vote of the pledged securities or the
           power to vote or direct the disposition of the pledged securities
           prior to a default, without any foreclosure or transfer of ownership
           shall not trigger the conversion of such Class B Common Stock.

                (ii) Subject to Article ELEVENTH, all of the outstanding shares
           of Class B Common Stock shall automatically be converted into shares
           of Class A Common Stock on a share for share basis without further
           action by the holders of the Common Stock at such time when the
           holders of the Class B Common Stock Beneficially Own less than 20% of
           the outstanding shares of Common Stock immediately prior to the time
           of conversion.

           (c)  CLASS B OR NBC PARENT AND ITS AFFILIATES' CONVERSION
       PROCEDURE.  Any conversion pursuant to this paragraph 9 shall be deemed
       to have been effected at the time (i) the holders of Class B Common Stock
       or NBC Parent and its Affiliates vote for or request such conversion in
       accordance with subsection (a) of this paragraph 9 or (ii) the Event of
       Conversion referred to in subsection (b) of this paragraph 9 occurred, as
       the case may be (the "Class B/NBC Parent Conversion Time"). At the Class
       B/NBC Parent Conversion Time, the certificate or certificates that
       represented immediately prior thereto the shares of Class B

                                     D-1-4
<PAGE>
       Common Stock (or Class A Common Stock, as the case may be) which were so
       converted (the "Converted Common Stock") shall, automatically and without
       further action, represent on a share for share basis the same number of
       shares of Class A Common Stock (or Class B Common Stock, as the case may
       be). Holders of Converted Common Stock shall deliver their certificates,
       duly endorsed in blank or accompanied by proper instruments of transfer,
       to the principal office of the Corporation or the office of any transfer
       agent for shares of Class A Common Stock (or Class B Common Stock, as the
       case may be), together with a written notice setting out the name or
       names (with addresses) and denominations in which the certificate or
       certificates representing such shares of Class A Common Stock (or Class B
       Common Stock, as the case may be) are to be issued and including
       instructions for delivery thereof. Upon such delivery, the Corporation or
       its transfer agent shall promptly issue and deliver at such stated
       address to such holder of shares of Class A Common Stock (or Class B
       Common Stock, as the case may be) a certificate or certificates
       representing the number of shares of Class A Common Stock (or Class B
       Common Stock, as the case may be) into which the Converted Common Stock
       was so converted and shall cause such shares of Class A Common Stock (or
       Class B Common Stock, as the case may be) to be registered in the name of
       such holder. The Corporation will issue certificates for the balance of
       the shares of Class B Common Stock (or Class A Common Stock, as the case
       may be) in any case in which fewer than all of the shares of Class B
       Common Stock (or Class A Common Stock, as the case may be) represented by
       a certificate are converted. The Person entitled to receive the shares of
       Class A Common Stock (or Class B Common Stock, as the case may be)
       issuable upon such conversion shall be treated for all purposes as the
       record holder of such shares of Class A Common Stock (or Class B Common
       Stock, as the case may be) and will have all the rights of record holders
       of shares of Class A Common Stock (or Class B Common Stock, as the case
       may be) at and as of the Class B/NBC Parent Conversion Time, and the
       rights of such Person as a holder of shares of Class B Common Stock (or
       Class A Common Stock, as the case may be) that have been converted shall
       cease and terminate at and as of the Class B/NBC Parent Conversion Time,
       in each case without regard to any failure by such holder to deliver the
       certificates or the notice required by this paragraph 9; PROVIDED,
       HOWEVER, that such Person shall be entitled to receive, when paid, any
       dividends declared on the Class B Common Stock (or Class A Common Stock,
       as the case may be) as of a record date preceding the Class B/ NBC Parent
       Conversion Time and unpaid as of the Class B/NBC Parent Conversion Time
       so long as such Person was the record holder when such dividends were
       declared. For purposes of this Restated Certificate of Incorporation,
       "Person" shall mean an individual or a corporation, association,
       partnership, limited liability company, joint venture, organization,
       business, trust or any other entity or organization, including a
       government or any subdivision or agency thereof.

           (d)  PAYMENT OF TRANSFER TAXES.  The Corporation will pay any and all
       documentary stamp or similar issue or transfer taxes payable in respect
       of the issue or delivery of shares of Class A Common Stock (or Class B
       Common Stock, as the case may be) on conversion of Class B Common Stock
       (or Class A Common Stock, as the case may be) pursuant hereto; PROVIDED,
       HOWEVER, that the Corporation shall not be required to pay any tax which
       may be payable in respect of any transfer involved in the issue or
       delivery of shares of Class A Common Stock (or Class B Common Stock, as
       the case may be) in a name other than that of the registered holder of
       the Class B Common Stock (or Class A Common Stock, as the case may be) to
       be converted and no such issue or delivery shall be made unless and until
       the Person requesting such issue or delivery has paid to the Corporation
       the amount of any such tax or has established, to the satisfaction of the
       Corporation, that such tax has been paid or is not applicable.

           (e)  RESERVATION OF CLASS A COMMON STOCK.  The Corporation shall at
       all times reserve and keep available, out of its authorized and unissued
       shares of Class A Common Stock, for the purposes of effecting
       conversions, such number of duly authorized shares of Class A Common
       Stock as shall from time to time be sufficient to effect the conversion
       of all outstanding shares of Class B Common Stock. All the shares of
       Class A Common Stock so issuable shall, when so issued, be duly and
       validly issued, fully paid and non-assessable, and free from liens and
       charges with respect to such issuance.

    10.  PURCHASE OF CLASS A COMMON STOCK BY CLASS B HOLDERS.

           (a)  AUTOMATIC CONVERSION OF CLASS A STOCK.  So long as shares of
       Class B Common Stock are outstanding, in the event a holder of Class B
       Common Stock or its Subsidiary purchases or otherwise acquires or holds
       any shares of Class A Common Stock (other than as a result of a
       conversion pursuant to paragraph 9 hereof), then such shares of Class A
       Common Stock shall automatically convert on a share for share basis into
       the same number of shares of Class B Common Stock.

           (b)  CLASS A CONVERSION PROCEDURE.  So long as shares of Class B
       Common Stock are outstanding, any conversion pursuant to this paragraph
       10 shall be deemed to have been effected at the time any holder of Class
       B Common Stock purchases or otherwise acquires any shares of Class A
       Common Stock (other than as a result of a conversion pursuant to
       paragraph 9 hereof) (the "Class A Conversion Time"). At the Class A
       Conversion Time, the certificate or certificates that represented
       immediately prior thereto the shares of Class A Common Stock which were
       so converted (the "Converted Class A Common Stock") shall, automatically
       and without further action, represent on a share for share basis the same
       number of shares of Class B Common Stock. Holders of Converted Class A
       Common Stock shall deliver their certificates, duly endorsed in blank or
       accompanied by proper instruments of transfer, to the principal office of
       the Corporation or the office of any transfer agent for shares of Class B
       Common Stock, together with a written notice setting out the name or
       names (with addresses) and denominations in which the certificate or
       certificates representing such shares of Class B Common Stock are to be
       issued and including instructions for delivery thereof. Upon such
       delivery, the Corporation or its transfer agent shall promptly issue and
       deliver at such stated address to such holder of shares of Class B Common
       Stock a certificate or certificates representing the number of shares of
       Class B Common Stock into which the Converted Class A Common Stock was so
       converted and shall cause such shares of Class B Common Stock to be
       registered in the name of such holder. The Person entitled to receive the
       shares of Class B Common Stock issuable upon such conversion shall be
       treated for all purposes as the record holder of such shares of Class B
       Common Stock at and will have all the rights of record holders of shares
       of Class B Common Stock at and as of the Class A Conversion Time, and the
       rights of such Person as a holder of shares of Class A Common Stock that
       have been converted shall cease and terminate at and as of the Class A
       Conversion Time, in each case without regard to any failure by such
       holder to deliver the certificates or the notice required by this
       paragraph 10; PROVIDED, HOWEVER, that such Person shall be entitled to
       receive when paid any dividends declared on the Class A Common Stock as
       of a record date preceding the Class A Conversion Time and unpaid as of
       the Class A Conversion Time, so long as such Person was the record holder
       when such dividends were declared.

           (c)  RESERVATION OF CLASS B COMMON STOCK.  So long as shares of Class
       B Common Stock are outstanding, the Corporation shall at all times
       reserve and keep available, out of its authorized and unissued shares of
       Class B Common Stock, for the purposes of effecting conversions, such
       number of duly authorized shares of Class B Common Stock as shall from
       time to time be sufficient to effect all possible conversions of Class A
       Common Stock to Class B Common Stock.

    11.  STOCKHOLDER VETO RIGHTS.

           (a) In addition to any other vote of stockholders required under this
       Restated Certificate of Incorporation, the Corporation's Bylaws or
       otherwise, and subject to the rights of the holders of Preferred Stock,
       none of the following actions may be taken by the Corporation without the
       approval of the holders of a majority of the outstanding shares of the
       Class A Common Stock:

                (i) any amendment to this Restated Certificate of Incorporation
           or Bylaws other than an amendment consisting solely of an increase in
           the authorized capital stock of the Corporation (except for
           amendments to the Bylaws duly approved by the Board of Directors);

                (ii) the issuance of Class B Common Stock to any Person except
           to NBC or its affiliates.

           (b) In addition to any other vote of stockholders required under this
       Restated Certificate of Incorporation, the Corporation's Bylaws or
       otherwise during such time, the approval of the holders of a majority of
       the outstanding shares of the Class B Common Stock shall be required to
       take any of the actions set forth in subparagraphs (i) or (ii) of
       subsection (a) of paragraph 11 or to adopt a stockholder rights plan or
       take other action which could adversely affect in any material respect
       the rights of any holder of Class B Common Stock by virtue of the amount
       of shares held by such holder.

    FIFTH: Except as otherwise required by law or by this Restated Certificate
of Incorporation, the business of the Corporation shall be managed by or under
the direction of its Board of Directors, which shall have and may exercise all
the powers of the Corporation.

        1.  COMPOSITION OF THE BOARD OF DIRECTORS.  For so long as there are
    shares of Class B Common Stock outstanding, the Board of Directors shall
    consist of thirteen directors (subject to paragraph (a) below) designated as
    follows and subject thereto:

           (a)  DIRECTORS:

                (i) During such time as the holders of Class B Common Stock
           Beneficially Own at least 35% of the outstanding shares of Common
           Stock, then the Board of Directors will be comprised as follows:

                   (A) If the Company Convertible Notes have not been converted
               in full into shares of Class B Common Stock, then the Board of
               Directors will consist of 13 members and (1) the holders of the
               Class B Common Stock voting separately as a class shall have the
               right to elect six members of the Board of Directors, (2) the
               holders of the Class A Common Stock voting separately as a class
               shall have the right to elect six members of the Board of
               Directors and (3) the holders of the Class A Common Stock voting
               separately as a class shall have the right to elect one
               Independent Director to the Board of Directors.

                   (B) If the Company Convertible Notes have been converted in
               full into shares of Class B Common Stock, then the Board of
               Directors shall consist of 13 members and (1) the holders of the
               Class B Common Stock voting separately as a class shall have the
               right to elect seven members of the Board of Directors and (2)
               the holders of the Class A Common Stock voting separately as a
               class shall have the right to elect six members of the Board of
               Directors; PROVIDED that if the holders of the Class B Common
               Stock have elected to reduce the number of directors they are
               entitled to elect from seven to six as provided in paragraph 2 of
               this Article FIFTH, the Board of Directors will consist of the
               members provided in clause (A) above.

                                     D-1-7
<PAGE>
                (ii) During such time as the holders of Class B Common Stock
           Beneficially Own at least 20% and less than 35% of the outstanding
           shares of Common Stock, then the holders of the Class B Common Stock
           shall have the right to elect six members to the Board of Directors
           and the holders of the Class A Common Stock shall have the right to
           elect seven members to the Board of Directors.

               (iii) For so long as the holders of Class B Common Stock have the
           right to elect directors to the Board of Directors pursuant to this
           paragraph 1, the holders of the Class B Common Stock shall not be
           entitled to vote in the election of any Class A Directors.

                (iv) At such time as the holders of Class B Common Stock become
           entitled to elect seven members to the Board of Directors under
           clause (i) of this paragraph (a) the Class B Nominating Committee (as
           defined in the Bylaws) shall be entitled to appoint a seventh Class B
           Director to the Board of Directors.

                (v) Subject to Article ELEVENTH, in the event the holders of
           Class B Common Stock Beneficially Own less than 35% (but at least
           20%) of the total outstanding shares of Common Stock, the Class A
           Nominating Committee shall be entitled to appoint a seventh Class A
           Director to the Board of Directors. Subject to Article ELEVENTH, if
           at such time there are seven Class B Directors serving on the Board
           of Directors, then the holders of Class B Common Stock shall cause
           one Class B Director to resign within 30 days after the date the
           Class B Common Stock constitutes less than 35% of the total
           outstanding shares of Common Stock (the "35% Resignation Date") and
           one Class A Director shall be appointed to the Board of Directors on
           the earlier of the date the Class B Director resigns or the 35%
           Resignation Date. If a Class B Director does not resign by the 35%
           Resignation Date, on such date the number of members comprising the
           Board of Directors shall automatically be increased to fifteen
           (provided that it shall automatically decrease to thirteen at the
           time of the election of directors at the next annual or special
           meeting of stockholders at which directors are elected) and the Class
           A Nominating Committee shall have full power and authority to appoint
           two additional Class A Directors to the Board of Directors.
           Immediately after the next annual or special meeting of the
           stockholders at which directors are elected, the number of directors
           constituting the whole Board of Directors shall be reduced to
           thirteen, with six directors elected by the holders of Class B Common
           Stock and seven directors elected by the holders of Class A Common
           Stock.

                (vi) From and after such time as there are no shares of Class B
           Common Stock outstanding, the number of directors of the Corporation
           shall not be less than seven nor more than sixteen as determined from
           time to time by the Board of Directors within such limitation.

           (b)  INDEPENDENT DIRECTOR.  During such time as the holders of the
       Class A Common Stock and the holders of the Class B Common Stock have the
       right to elect an equal number of members to the Board of Directors,
       there shall be appointed to the Board of Directors an additional member
       (the "Independent Director"). The approval of at least seven of the
       members of the Board of Directors will be required for the Corporation to
       nominate the Independent Director for election or to appoint an
       Independent Director to the Board of Directors. The nomination of the
       Independent Director by the Corporation shall be performed by the Board
       of Directors and not by the Class A Nominating Committee and/or the Class
       B Nominating Committee. The Independent Director's term of office shall
       automatically expire at such time as (i) the Class B Nominating Committee

derived by the Corporation through its contractual, corporate and business
relations with NBC (including possible service of officers and directors of NBC
as officers and directors of the Corporation) and there will be benefits in
providing guidelines for directors and officers of NBC and its affiliates and of
the Corporation with respect to the allocation of corporate opportunities and
other matters; the provisions of this Article THIRTEENTH, are set forth to
regulate, define and guide the conduct of certain affairs of the Corporation as
they may involve NBC and its officers and directors, and the powers, rights,
duties and liabilities of the Corporation and its officers, directors and
stockholders in connection therewith; PROVIDED, HOWEVER, that nothing in this
Article THIRTEENTH will impede the Corporation's ability to enter into
contractual arrangements with a stockholder of the Corporation, which
arrangements restrict the stockholder from engaging in activities otherwise
allowed by this Article THIRTEENTH, and the following provisions shall be
subject to any such contractual obligation of the Corporation.

    1.  NBC shall have the right to, and shall have no duty hereunder to refrain
from, engaging in the same or similar activities or lines of business as the
Corporation, doing business with any potential or actual customer or supplier of
the Corporation, or employing or otherwise engaging any officer or employee of
the Corporation. To the fullest extent permitted by law, neither NBC nor any
officer or director thereof shall be liable to the Corporation or its
stockholders for breach of any fiduciary duty by reason of any such activities
of NBC, or the participation therein of such person. In the event that NBC
acquires knowledge of a potential transaction or matter which may be a corporate
opportunity for both NBC and the Corporation, NBC shall have no duty to
communicate or present such corporate opportunity to the Corporation, and shall
not be liable to the Corporation or its stockholders for breach of any fiduciary
duty as a stockholder of the Corporation by reason of the fact that NBC pursues
or acquires such corporate opportunity for itself, directs such corporate
opportunity to another person, or does not communicate information regarding
such corporate opportunity to the Corporation.

    2.  In the event that a director or officer of the Corporation who is also a
director or officer of NBC acquires knowledge of a potential transaction or
matter which may be a corporate opportunity for both the Corporation and NBC, to
the fullest extent permitted by law (i) such director or officer of the
Corporation shall be deemed to have fully satisfied and fulfilled the fiduciary
duty of such director or officer to the Corporation and its stockholders with
respect to such corporate opportunity, (ii) shall not be liable to the
Corporation or its stockholders for breach of any fiduciary duty by reason of
the fact that NBC or any of its affiliates pursues or acquires such corporate
opportunity for itself or directs such corporate opportunity to another Person
(including, without limitation, NBC or any of its affiliates) or does not
communicate information regarding such corporate opportunity to the Corporation,
(iii) shall be deemed to have acted in good faith and in a manner such Person
reasonably believes to be in or not opposed to the best interests of the
Corporation, and (iv) shall be deemed not to have breached his or her duty of
loyalty to the Corporation or its stockholders and not to have derived an
improper benefit therefrom, if such director or officer acts in a manner
consistent with the following policy:

            (i) A corporate opportunity offered to any person who is an officer
       of the Corporation, and who is also a director but not an officer of NBC,
       shall belong to the Corporation; (ii) a corporate opportunity offered to
       any person who is a director but not an officer of the Corporation, and
       who is also a director or officer of NBC shall belong to the Corporation
       if such opportunity is expressly offered to such person in writing solely
       in his or her capacity as a director of the Corporation, and otherwise
       shall belong to NBC; and (iii) a corporate

                                     D-1-13
<PAGE>
       opportunity offered to any person who is an officer of both the
       Corporation and NBC shall belong to the Corporation if such opportunity
       is expressly offered to such person in writing solely in his or her
       capacity as an officer of the Corporation, and otherwise shall belong to
       NBC.

    3.  Any corporate opportunity that belongs to NBC or any of its affiliates
or to the Corporation pursuant to the foregoing policy shall not be pursued by
the other, unless and until the party to whom the opportunity belongs determines
not to pursue the opportunity and so informs the other party. Notwithstanding
the preceding sentence, if the party to whom the corporate opportunity belongs
does not within 30 calendar days begin to pursue, or thereafter continue to
pursue, such opportunity diligently and in good faith, the other party may then
pursue such opportunity.

    4.  To avoid any appearance that the Board of Directors is not acting
independently and in the best interest of the stockholders, the approval of a
majority of the Class A Directors, voting separately as a group, shall be
required to commence any action, suit or proceeding against any Restricted Party
(as defined in the Governance Agreement) or take or approve or enter into any
transaction, action or other arrangement including any Restricted Party
(including resolving any dispute) that would otherwise require the action of the
full Board of Directors.

the capital stock of the Corporation shall be deemed to have notice of and to
have consented to the provisions of this Article THIRTEENTH.

    Corporation under the Bylaws of the Corporation), unless such person is a
    full-time employee of the Corporation; and

    or more of the outstanding voting stock, voting power, partnership interests
    or similar voting interests.

        For purposes of this Article THIRTEENTH, "corporate opportunities" shall
    consist of business opportunities which (i) the Corporation is financially
    able to undertake, (ii) are, from their nature, in the line or lines of the
    Corporation's business and are of practical advantage to it, and (iii) are
    ones in which the Corporation has an interest or reasonable expectancy.

    7.  Notwithstanding anything in this Restated Certificate of Incorporation
to the contrary, (i) the foregoing provisions of this Article THIRTEENTH shall
expire on the date that NBC ceases to Beneficially Own Common Stock representing

be required to alter, amend or repeal (by merger or otherwise) in a manner
adverse to the interests of NBC, or adopt any provision adverse to the interests
of NBC and

                                     D-1-14

claim that, but for this Article THIRTEENTH, would accrue or arise, prior to
such alteration, amendment, repeal or adoption.

SECTION 2.1  PLACE OF MEETINGS.

    Meetings of the stockholders of the Corporation shall be held at such place,
either within or without the State of Delaware, as may be designated from time
to time by the Board of Directors, or, if not so designated, then at the

Section 1.1 of Article I hereof.

SECTION 2.2  ANNUAL MEETINGS.

    The annual meetings of the stockholders of the Corporation for the purpose
of election of directors and for such other business as may lawfully come before
it, shall be held on such date and at such time as may be designated from time
to time by the Board of Directors.

SECTION 2.3  SPECIAL MEETINGS.

    Special Meetings of the stockholders of the Corporation may be called, for
any purpose or purposes, by the Chairman of the Board, Chief Executive Officer
or President, the Board of Directors at any time or by the holders of at least a
majority of the outstanding shares of Class B Common Stock. Special meetings of
the stockholders of the Corporation may not be called by any other person or
persons. No business may be transacted at any special meeting except that
referred to in the notice thereof.

SECTION 2.4  NOTICE OF MEETINGS.

    (a) Except as otherwise provided by law or the Restated Certificate of
Incorporation, written notice of each meeting of stockholders, specifying the
place, date and hour and purpose or purposes of the meeting, shall be given not
less than ten nor more than sixty days before the date of the meeting to each
stockholder entitled to vote thereat, directed to his address as it appears upon
the books of the

                                     D-2-1
<PAGE>
Corporation; except that where the matter to be acted on is a merger or
consolidation of the Corporation or a sale, lease or exchange of all or
substantially all of its assets, such notice shall be given not less than twenty
(20) nor more than sixty (60) days prior to such meeting.

    (b) If at any meeting action is proposed to be taken which, if taken, would
entitle stockholders fulfilling the requirements of section 262(d) of the
Delaware Corporation Law to an appraisal of the fair value of their shares, the
notice of such meeting shall contain a statement of that purpose and to that
effect and shall be accompanied by a copy of that statutory section.

    (c) When a meeting is adjourned to another time or place, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken. At the adjourned meeting the
Corporation may transact any business which might have been transacted at the
original meeting. If the adjournment is for more than thirty days, or if after
the adjournment a new record date is fixed for the adjourned meeting, a notice
of the adjourned meeting shall be given to each stockholder of record entitled
to vote at the meeting.

    (d) Notice of the time, place and purpose of any meeting of stockholders may
be waived in writing, either before or after such meeting, and to the extent
permitted by law, will be waived by any stockholder by his attendance thereat,
in person or by proxy. Any stockholder so waiving notice of such meeting shall
be bound by the proceedings of any such meeting in all respects as if due notice
thereof had been given.

SECTION 2.5  QUORUM AND VOTING.

    (a) At all meetings of stockholders, except where otherwise provided by law,
the Restated Certificate of Incorporation, or these Bylaws, the presence in
person or by proxy, duly authorized, of the holders of shares entitled to cast a
majority of all the votes which could be cast at such meeting by the holders of
all of the outstanding shares of capital stock of the Corporation entitled to
vote on every matter that is to be voted on at such meeting shall constitute a
quorum; PROVIDED, FURTHER, that any action of the Corporation approved or
recommended by the stockholders of the Corporation will be subject to the
appropriate approval of the holders of the Class A Common Stock and Class B
Common Stock pursuant to paragraphs 11(a) and 11(b) of Article Fourth of the
Restated Certificate of Incorporation of the Corporation. In the absence of a
quorum, any meeting of stockholders may be adjourned, from time to time, by vote
of the holders of a majority of the shares represented thereat, but no other
business shall be transacted at such meeting. At such adjourned meeting at which
a quorum is present or represented any business may be transacted which might
have been transacted at the original meeting. The stockholders present at a duly
called or convened meeting, at which a quorum is present, may continue to
transact business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

    (b) Except as otherwise provided by law, the Restated Certificate of
Incorporation or these Bylaws, all action taken by the holders of a majority of
the shares voting "for" or "against" at any meeting at which a quorum is present
shall be valid and binding upon the Corporation.

    (c) Except as otherwise provided by law, the Restated Certificate of
Incorporation or these Bylaws, where a separate vote by a class or classes is
required, a majority of the outstanding shares of such class or classes, present
in person or represented by proxy, shall constitute a quorum entitled to take
action with respect to that vote on that matter and the affirmative vote of the
majority of shares of such class or classes present in person or represented by
proxy at the meeting shall be the act of such class.

                                     D-2-2
<PAGE>
SECTION 2.6  VOTING RIGHTS; PROXIES.

    (a) Except as otherwise provided by law or in the Restated Certificate of
Incorporation, only persons in whose names shares entitled to vote stand on the
stock records of the Corporation on the record date for determining the
stockholders entitled to vote at said meeting shall be entitled to vote at such
meeting. Shares standing in the names of two or more persons shall be voted or
represented in accordance with the determination of the majority of such
persons, or, if only one of such persons is present in person or represented by
proxy, such person shall have the right to vote such shares and such shares
shall be deemed to be represented for the purpose of determining a quorum.

    (b) Every person entitled to vote or execute consents shall have the right
to do so either in person or by an agent or agents authorized by a proxy, which
proxy shall be filed with the Secretary of the Corporation at or before the
meeting at which it is to be used. Said proxy so appointed need not be a
stockholder. No proxy shall be voted on after three years from its date unless
the proxy provides for a longer period. Unless and until voted, every proxy
shall be revocable at the pleasure of the person who executed it or of his legal
representatives or assigns, except in those cases where an irrevocable proxy
permitted by statute has been given.

    (c) Without limiting the manner in which a stockholder may authorize another
person or persons to act for him as proxy pursuant to subsection (b) of this
section, the following shall constitute a valid means by which a stockholder may
grant such authority:

        (1) A stockholder may execute a writing authorizing another person or
    persons to act for him as proxy. Execution may be accomplished by the
    stockholder or his authorized officer, director, employee or agent signing
    such writing or causing his or her signature to be affixed to such writing
    by any reasonable means including, but not limited to, by facsimile
    signature.

        (2) A stockholder may authorize another person or persons to act for him
    as proxy by transmitting or authorizing the transmission of a telegram,
    cablegram, or other means of electronic transmission to the person who will
    be the holder of the proxy or to a proxy solicitation firm, proxy support
    service organization or like agent duly authorized by the person who will be
    the holder of the proxy to receive such transmission; PROVIDED, that any
    such telegram, cablegram or other means of electronic transmission must
    either set forth or be submitted with information from which it can be
    determined that the telegram, cablegram or other electronic transmission was
    authorized by the stockholder. Such authorization can be established by the
    signature of the stockholder on the proxy, either in writing or by a
    signature stamp or facsimile signature, or by a number or symbol from which
    the identity of the stockholder can be determined, or by any other procedure
    deemed appropriate by the inspectors or other persons making the
    determination as to due authorization. If it is determined that such
    telegrams, cablegrams or other electronic transmissions are valid, the
    inspectors or, if there are no inspectors, such other persons making that
    determination shall specify the information upon which they relied.

    (d) Any copy, facsimile telecommunication or other reliable reproduction of
the writing or transmission created pursuant to subsection (c) of this section
may be substituted or used in lieu of the original writing or transmission for
any and all purposes for which the original writing or transmission could be
used; PROVIDED that such copy, facsimile telecommunication or other reproduction
shall be a complete reproduction of the entire original writing or transmission.

SECTION 2.7  VOTING PROCEDURES AND INSPECTORS OF ELECTIONS.

    (a) The Corporation shall, in advance of any meeting of stockholders,
appoint one or more inspectors to act at the meeting and make a written report
thereof. The Corporation may designate one or more persons as alternate
inspectors to replace any inspector who fails to act. If no inspector or
alternate is able to act at a meeting of stockholders, the person presiding at
the meeting shall appoint

                                     D-2-3
<PAGE>
one or more inspectors to act at the meeting. Each inspector, before entering
upon the discharge of his duties, shall take and sign an oath faithfully to
execute the duties of inspector with strict impartiality and according to the
best of his ability.

    (b) The inspectors shall (i) ascertain the number of shares outstanding and
the voting power of each, (ii) determine the shares represented at a meeting and
the validity of proxies and ballots, (iii) count all votes and ballots, (iv)
determine and retain for a reasonable period a record of the disposition of any
challenges made to any determination by the inspectors, and (v) certify their
determination of the number of shares represented at the meeting, and their
count of all votes and ballots. The inspectors may appoint or retain other
persons or entities to assist the inspectors in the performance of the duties of
the inspectors.

    (c) The date and time of the opening and the closing of the polls for each
matter upon which the stockholders will vote at a meeting shall be announced at
the meeting. No ballot, proxies or votes, nor any revocations thereof or changes
thereto, shall be accepted by the Inspectors after the closing of the polls
unless the Court of Chancery upon application by a stockholder shall determine
otherwise.

    (d) In determining the validity and counting of proxies and ballots, the
inspectors shall be limited to an examination of the proxies, any envelopes
submitted with those proxies, any information provided in accordance with
Section 212(c)(2) of the Delaware Corporation Law, ballots and the regular books
and records of the Corporation, except that the inspectors may consider other
reliable information for the limited purpose of reconciling proxies and ballots
submitted by or on behalf of banks, brokers, their nominees or similar persons
which represent more votes than the holder of a proxy is authorized by the
record owner to cast or more votes than the stockholder holds of record. If the
inspectors consider other reliable information for the limited purpose permitted
herein, the inspectors at the time they make their certification pursuant to
subsection (b)(v) of this section shall specify the precise information
considered by them including the person or persons from whom they obtained the
information, when the information was obtained, the means by which the
information was obtained and the basis for the inspectors' belief that such
information is accurate and reliable.

SECTION 2.8  LIST OF STOCKHOLDERS.

    The officer who has charge of the stock ledger of the Corporation shall
prepare and make, at least ten days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at said meeting, arranged in
alphabetical order, showing the address of and the number of shares registered
in the name of each stockholder. Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held and which place shall
be specified in the notice of the meeting, or, if not specified, at the place
where said meeting is to be held, and the list shall be produced and kept at the
time and place of meeting during the whole time thereof, and may be inspected by
any stockholder who is present.

SECTION 2.9  NOTICE OF STOCKHOLDER BUSINESS AND NOMINATIONS.

    (a)  ANNUAL MEETING OF STOCKHOLDERS.  (i) Nominations of persons for
election to the Board of Directors of the Corporation and the proposal of
business to be considered by the stockholders may be made at an annual meeting
of stockholders only (A) pursuant to the Corporation's notice of meeting (or any
supplement thereto), (B) by or at the direction of the Board of Directors, (C)
by the holders of a majority of the outstanding shares of Class B Common Stock,
which holders shall not be required to comply with the notice provisions set
forth in this Section 2.9; PROVIDED that this clause (C) will not permit such
holders to nominate Class A Directors or (D) by any stockholder of the
Corporation who was a stockholder of record of the Corporation at the time the
notice provided for in this Section 2.9 is

                                     D-2-4
<PAGE>
delivered to the Secretary of the Corporation, who is entitled to vote at the
meeting and who complies with the notice procedures set forth in this Section
2.9.

    (ii) For nominations or other business to be properly brought before an
annual meeting by a stockholder pursuant to clause (D) of paragraph (a)(i) of
this Section 2.9, the stockholder must have given timely notice thereof in
writing to the Secretary of the Corporation and any such proposed business other
than the nominations of persons for election to the Board of Directors must
constitute a proper matter for stockholder action. To be timely, such a
stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the Corporation not later than the close of business on the
ninetieth day nor earlier than the close of business on the one hundred
twentieth day prior to the first anniversary of the preceding year's annual
meeting; PROVIDED, HOWEVER, that in the event that the date of the annual
meeting is more than thirty days before or more than seventy days after such
anniversary date, notice by the stockholder must be so delivered not earlier
than the close of business on the one hundred twentieth day prior to such annual
meeting and not later than the close of business on the later of the ninetieth
day prior to such annual meeting or the tenth day following the day on which
public announcement of the date of such meeting is first made by the
Corporation. In no event shall the public announcement of an adjournment or
postponement of an annual meeting commence a new time period (or extend any time
period) for the giving of a stockholder's notice as described above. Such
stockholder's notice shall set forth: (A) as to each person whom the stockholder
proposes to nominate for election as a director all information relating to such
person that is required to be disclosed in solicitations of proxies for election
of directors in an election contest, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act") and Rule 41a-11 thereunder (and such person's written
consent to being named in the proxy statement as a nominee and to serving as a
director if elected); (B) as to any other business that the stockholder proposes
to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the text of the proposal or business (including the
text of any resolutions proposed for consideration and in the event that such
business includes a proposal to amend the Bylaws of the Corporation, the
language of the proposed amendment), the reasons for conducting such business at
the meeting and any material interest in such business of such stockholder and
the beneficial owner, if any, on whose behalf the proposal is made; and (C) as
to the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made (1) the name and address of such
stockholder, as they appear in the Corporation's books, and of such beneficial
owner, (2) the class and number of shares of capital stock of the corporation
which are owned beneficially and of record by such stockholder and such
beneficial owner, (3) a representation that the stockholder is a holder of
record of stock of the Corporation entitled to vote at such meeting and intends
to appear in person or by proxy at the meeting to propose such business or
nomination, and (4) a representation whether the stockholder or the beneficial
owner, if any, intends or is part of a group which intends (a) to deliver a
proxy statement or form of proxy to holders of at least the percentage of the
Corporation's outstanding capital stock required to approve or adopt the
proposal or elect the nominee or (b) otherwise to solicit proxies from
stockholders in support of such proposal or information as it may reasonably
require to determine the eligibility of such proposed nominee to serve as a
director of the Corporation.

   (iii) Notwithstanding anything in the second sentence of paragraph (a)(ii) of
this Section 2.9 to the contrary, in the event that the number of directors to
be elected to the Board of Directors of the Corporation at an annual meeting is
increased and there is no public announcement by the Corporation naming the
nominees for the additional directorships at least one hundred days prior to the
first anniversary of the preceding year's annual meeting, a stockholder's notice
required by this Section 2.9 shall also be considered timely, but only with
respect to nominees for the additional directorships, if it shall be delivered
to the Secretary at the principal executive offices of the Corporation not later
than the close of business on the tenth day following the day on which such
public announcement is first made by the Corporation.

                                     D-2-5
<PAGE>
    (b)  SPECIAL MEETING OF STOCKHOLDERS.  Only such business shall be conducted
at a special meeting of stockholders as shall have been brought before the
meeting pursuant to the Corporation's notice of meeting. Nominations of persons
for election to the Board of Directors may be made at a special meeting of
stockholders at which directors are to be elected pursuant to the Corporation's
notice of meeting (i) by or at the direction of the Board of Directors, or (ii)
provided that the Board of Directors has determined that directors shall be
elected at such meeting, by any stockholder of the Corporation who is a
stockholder of record at the time the notice provided for in this Section 2.9 is
delivered to the Secretary of the Corporation, who is entitled to vote at the
meeting and upon such election and who complies with the notice procedures set
forth in this Section 2.9. In the event the Corporation calls a special meeting
of stockholders for the purpose of electing one or more directors to the Board
of Directors, any such stockholder entitled to vote in such election of
directors may nominate a person or persons (as the case may be) for election to
such position(s) as specified in the Corporation's notice of meeting, if the
stockholder's notice required by paragraph (a)(ii) of this Section 2.9 shall be
delivered to the Secretary at the principal executive offices of the Corporation
not earlier than the close of business on the one hundred twentieth day prior to
such special meeting and not later than the close of business on the later of
the ninetieth day prior to such special meeting or the tenth day following the
day on which public announcement is first made of the date of the special
meeting and of the nominees proposed by the Board of Directors to be elected at
such meeting. In no event shall the public announcement of an adjournment or
postponement of a special meeting commence a new time period (or extend any time
period) for the giving of a stockholder's notice as described above.

    (c)  GENERAL.  (i) Only such persons who are nominated in accordance with
the procedures set forth in this Section 2.9 shall be eligible to be elected at
an annual or special meeting of stockholders of the Corporation to serve as
directors and only such business shall be conducted at a meeting of stockholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 2.9. Except as otherwise provided by law, the chairman
of the meeting shall have the power and duty (A) to determine whether a

as the director who resigned, including those who have so resigned, shall have
power to fill such vacancy or vacancies, the vote thereon to take effect when

and Class B Directors, voting separately, otherwise agree. The provisions of
this paragraph shall not apply to Sections 3.9(b), (c) and (d) herein.

approve or recommend to the stockholders any action which must be submitted to
stockholders for approval under the General Corporation Law.

    (b) NOMINATING COMMITTEE: Notwithstanding anything contained in this Section
3.9 to the contrary, so long as there remain shares of Class B Common Stock
outstanding, there shall be a "Class A Nominating Committee" comprised solely of
Class A Directors, and a "Class B Nominating Committee" comprised solely of
Class B Directors. Subject to any rights of stockholders under law to nominate
persons to serve as directors, (i) the Class A Nominating Committee shall
nominate persons to serve as Class A Directors and shall appoint persons to fill

Class B Committee shall have the power and authority to consent to or approve
any action required to be approved by the Class B Directors pursuant to
paragraph 4 of Article FIFTH of the Restated Certificate of Incorporation of the
Corporation. If the Class B Committee is presented with any matter for its
approval, within five business days of the request for approval it will either
(i) grant such approval, (ii) deny such approval or (iii) require that such
request for approval be considered by all of the Class B Directors (in which

appointed such committee. The Board, subject to the requirements specifically
set forth in this Section 3.9, may at any time increase or decrease the number
of members of a committee or terminate the existence of a committee; PROVIDED,
that no committee shall consist of less than two (2) members. The membership of
a committee member shall terminate on the date of his death or voluntary
resignation, but the Board may at any time for any reason remove any individual
committee member and the Board may, subject to the requirements specifically set
forth in this Section 3.9, fill any committee vacancy created by death,
resignation, removal or increase in the number of members of the committee. The
Board of Directors may, subject to the requirements specifically set forth in
this Section 3.9, designate one or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of

designated from time to time by resolution of such committee or by written
consent of all members thereof, and may be called by any director who is a

and will be waived by any director by attendance thereat, except where a
director attends for the express purpose of objecting at the beginning of a
meeting to the transaction of any business because the meeting is not lawfully
called or convened. A majority of the authorized number of members of any such
committee shall constitute a quorum for the transaction of business; PROVIDED
that any action of the Corporation approved or recommended by any committee of
the Board of Directors will be subject to appropriate consents and approvals of
the Class A Directors or the Class B Directors voting as a group pursuant to

SECTION 4.1  ENUMERATION, ELECTION AND TERM.

    The officers of the Corporation shall consist of a President, a Secretary, a
Treasurer and such other officers with such other titles as may be deemed
necessary or desirable by the Board of Directors, including a Chief Executive
Officer, Chief Financial Officer, one or more Vice Presidents, a Controller,
Assistant Treasurers and Assistant Secretaries and a Chairman of the Board. Any
number of offices may be held by the same person, and no officer need be a

by law, the Restated Certificate of Incorporation or these Bylaws, each officer
shall hold office until his successor is elected and qualified or until his
earlier death, resignation or removal. The officers of the Corporation shall be
elected annually by the Board of Directors at the first meeting of the Board

    All officers and agents of the Corporation, as between themselves and the
Corporation, shall have such authority and shall perform such duties in the
management of the Corporation as may be provided in these Bylaws or as may be
determined by resolution of the Board of Directors not inconsistent with these
Bylaws. In all cases where the duties of any officer, agent or employee are not
prescribed by these Bylaws or by the Board of Directors, such officer, agent or
employee shall follow the orders and instructions of the President.

SECTION 4.3  VACANCIES.

    The Board of Directors may fill any vacancy occurring in any office for any

The officer so selected shall hold office until his successor is elected and
qualified or until his earlier death, resignation or removal.

SECTION 4.4  COMPENSATION.

    The Board of Directors from time to time shall fix the compensation of the
officers of the Corporation. The compensation of other agents and employees of

officer or agent of the Corporation may be removed, with or without cause, by a
vote of the majority of the members of the Board of Directors whenever in its
judgment the best interests of the Corporation may be served thereby, but such
removal shall be without prejudice to the contract rights, if any, of the person
so removed. Election or appointment of an officer or an agent shall not of
itself create contract rights.

SECTION 4.6  CHAIRMAN OF THE BOARD.

other duties as the Board may prescribe that he perform. At the request of the
President, the Chairman of the Board may, in the case of the President's absence
or inability to act, temporarily act in his place. In the case of death of the
President or in the case of his absence or inability to act without having
designated the Chairman of the Board to act temporarily in his place, the
Chairman of the Board shall perform the duties of the President, unless the
Board of Directors, by resolution, provides otherwise. If the Chairman of the
Board shall be unable to act in place of the President, the Vice Presidents may
exercise such powers and perform such duties as provided below.

discharge the duties of the presiding officer. At each annual meeting of the
stockholders, the President shall give a report of the business of the
Corporation for the preceding fiscal year and shall perform whatever other

corporate funds and securities and shall keep full and accurate accounts of

valuable effects in the name and to the credit of the Corporation in the
depository or depositories of the Corporation, and shall render an account his
or her transactions as Chief Financial Officer and of the financial condition of
the Corporation to the President and/or the Board of Directors upon request.
Such power given to the Treasurer to deposit and disburse funds shall not,
however, preclude any other officer or employee of the Corporation from also
depositing and disbursing funds when authorized to do so by the Board of
Directors. The Chief Financial Officer shall, if required by the Board of
Directors, give the Corporation a bond in such amount and with such surety or
sureties as may be ordered by the Board of Directors for the faithful
performance of the duties of his office. The Chief Financial Officer shall have
such other powers and perform such other duties as may be from time to time
prescribed by the Board of Directors or the President. In the absence of the

authority and shall be subject to the same restrictions as are applicable to the
Chief Financial Officer.

SECTION 4.10  VICE PRESIDENTS.

    Each Vice President shall have such powers and perform such duties as the
Board of Directors may from time to time prescribe or as the President may from
time to time delegate to him. At the request of the President, in the case of
the President's absence or inability to act, any Vice President may temporarily
act in his place. In the case of the death of the President, or in the case of
his absence

                                     D-2-12
<PAGE>
or inability to act without having designated a Vice President or Vice
Presidents to act temporarily in his place, the Board of Directors, by
resolution, may designate a Vice President or Vice Presidents to perform the
duties of the President. If no such designation shall be made, the Chief
Executive Officer, if any, shall exercise such powers and perform such duties,
as provided above, but, if the Corporation has no Chief Executive Officer, or if
the Chief Executive Officer is unable to act in place of the President, all of
the Vice Presidents may exercise such powers and perform such duties.

SECTION 4.11  SECRETARY.

    The Secretary shall keep or cause to be kept in books provided for that

if any, and any other committees, and of the Board of Directors; shall see that

SECTION 6.1  FORM AND EXECUTION OF CERTIFICATES.

    Certificates for the shares of stock of the Corporation shall be in such
form as is consistent with the Restated Certificate of Incorporation and
applicable law. Every holder of stock in the Corporation shall be entitled to

of the Board (if there be such an officer appointed), or by the President or any
Vice-President and by the Treasurer or Assistant Treasurer or the Secretary or
Assistant Secretary, certifying the number of shares owned by him in the
Corporation. Any or all of the signatures on the certificate may be a facsimile.
In case any officer, transfer agent, or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent, or registrar before such certificate is issued, it
may be issued with the same effect as if he were such officer, transfer agent,
or registrar at the date of issue. If the Corporation shall be authorized to
issue more than one class of stock or more than one series of any class, the
powers, designations, preferences and relative, participating, optional or other
special rights of each class of stock or series thereof and the qualifications,

that, except as otherwise provided in Section 202 of the Delaware Corporation
Law, in lieu of the foregoing requirements, there may be set forth on the face
or back of the certificate which the Corporation shall issue to represent such
class or series of stock, a statement that the Corporation will furnish without

issued in place of any certificate or certificates theretofore issued by the
Corporation alleged to have been lost or destroyed, upon the making of an
affidavit of that fact by the person claiming the certificate of stock to be
lost or destroyed. When authorizing such issue of a new certificate or
certificates, the Board of Directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost or destroyed
certificate or certificates, or his legal representative, to indemnify the
Corporation in such manner as it shall require and/or to give the Corporation a
surety bond in such form and amount as it may direct as indemnity against any
claim that may be made against the Corporation with respect to the certificate
alleged to have been lost or destroyed.

SECTION 6.3  TRANSFERS.

    Transfers of record of shares of stock of the Corporation shall be made only
upon its books by the holders thereof, in person or by attorney duly authorized,

the Board of Directors, and which record date shall not be more than sixty nor
less than ten days before the date of such meeting. If no record date is fixed
by the Board of Directors, the record date for determining stockholders entitled
to notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the date on
which the meeting is held. A determination of stockholders of record entitled
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; PROVIDED, HOWEVER, that the Board of Directors may fix a new
record date for the adjourned meeting.

    (b) In order that the Corporation may determine the stockholders entitled to
consent to corporate action in writing without a meeting, the Board of Directors
may fix a record date, which record date shall not precede the date upon which
the resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining stockholders entitled to consent to corporate action in writing
without a meeting, when no prior action by the Board of Directors is required by
the Delaware Corporation Law, shall be the first date on which a signed written
consent setting forth the action taken or proposed to be taken is delivered to
the Corporation by delivery to its registered office in Delaware, its principal
place of business, or an officer or agent of the Corporation having custody of
the book in which proceedings of meetings of stockholders are recorded. Delivery
made to a corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the Board of Directors and prior action by the Board of Directors is required by
law, the record date for determining stockholders entitled to consent to
corporate action in writing without a meeting shall be at the close of business
on the day on which the Board of Directors adopts the resolution taking such
prior action.

    (c) In order that the Corporation may determine the stockholders entitled to
receive payment of any dividend or other distribution or allotment of any rights
or the stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty days prior to such action. If
no record date is fixed, the record date for determining stockholders for any
such purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

SECTION 6.5  REGISTERED STOCKHOLDERS.

    The Corporation shall be entitled to recognize the exclusive right of a
person registered on its books as the owner of shares to receive dividends, and
to vote as such owner, and shall not be bound to recognize any equitable or
other claim to or interest in such share or shares on the part of any other
person, whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of Delaware.

                      OTHER SECURITIES OF THE CORPORATION

    All bonds, debentures and other corporate securities of the Corporation,
other than stock certificates, may be signed by the Chairman of the Board (if
there be such an officer appointed), or the President or any Vice-President or
such other person as may be authorized by the Board of Directors and the
corporate seal impressed thereon or a facsimile of such seal imprinted thereon
and attested by the signature of the Secretary or an Assistant Secretary, or the
Treasurer or an Assistant Treasurer; PROVIDED, HOWEVER, that where any such
bond, debenture or other corporate security shall be authenticated by the manual
signature of a trustee under an indenture pursuant to which such bond, debenture
or other corporate security shall be issued, the signature of the persons
signing and attesting the corporate seal on such bond, debenture or other
corporate security may be the imprinted facsimile of the signatures of such
persons. Interest coupons appertaining to any such bond, debenture or other
corporate security, authenticated by a trustee as aforesaid, shall be signed by
the Treasurer or an Assistant Treasurer of the Corporation, or such other person
as may be authorized by the Board of Directors, or bear imprinted thereon the
facsimile signature of such person. In case any officer who shall have signed or
attested any bond, debenture or other corporate security, or whose facsimile
signature shall appear thereon or before the bond, debenture or other corporate
security so signed or attested shall have been delivered, such bond, debenture
or other corporate security nevertheless may be adopted by the Corporation and
issued and delivered as though the person who signed the same or whose facsimile
signature shall have been used thereon had not ceased to be such officer of the
Corporation.

                                  ARTICLE VIII

          INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS

SECTION 9.1  RIGHT TO INDEMNIFICATION.

    (a) Each person who was or is a party or is threatened to be made a party to
or is involved (as a party, witness or otherwise), in any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "Proceeding"), by reason of the fact that he, or a
person of whom he is the legal representative, is or was a director or officer
of the Corporation or, while a director or officer of the Corporation, is or was
serving at the request of the Corporation as a director or officer of another
corporation or of a partnership, joint venture, trust, or other enterprise,
including service with respect to employee benefit plans, whether the basis of
the Proceeding is alleged action in an official capacity as a director or
officer or in any other capacity while serving as a director or officer, shall
be indemnified and held harmless by the Corporation to the fullest extent
authorized by the Delaware Corporation Law, as the same exists or may hereafter
be amended or interpreted, against all expenses, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties, and amounts
paid or to be paid in settlement, and any interest, assessments or other charges
imposed thereon, and any federal, state, local or foreign taxes imposed on any
person indemnified hereby as a result of the actual or deemed receipt of any
payments under this Article IX) reasonably incurred or suffered by such person
in connection with investigating, defending, being a witness in, or
participating in (including on appeal), or preparing for any of the foregoing
in, any

                                     D-2-16
<PAGE>
Proceeding (hereinafter "Losses"); PROVIDED, HOWEVER, that except as to actions
to enforce indemnification rights pursuant to Section 9.3 of Article IX, the
Corporation shall indemnify any officer or director seeking indemnification in
connection with a Proceeding (or part thereof) initiated by such person only if
the Proceeding (or part thereof) was authorized by the Board of Directors of the
Corporation. The right to indemnification conferred in this Article IX shall be
a contract right.

    (b) Each person who was or is a party or is threatened to be made a party to
or is involved (as a party, witness or otherwise), in any threatened, pending or
completed Proceeding, by reason of the fact that he, or a person of whom he is
the legal representative, is or was an employee or agent (other than an officer
or director) of the Corporation or is or was serving at the request of the
Corporation as an employee or agent (other than an officer or director) of
another corporation or of a partnership, joint venture, trust, or other
enterprise, including service with respect to employee benefit plans, whether
the basis of the Proceeding is alleged action in an official capacity as an
employee or agent or in any other capacity while serving as an employee or
agent, may be indemnified and held harmless by the Corporation to the fullest
extent authorized by the Delaware Corporation Law, as the same exists or may
hereafter be amended or interpreted against all Losses.

SECTION 9.2  AUTHORITY TO ADVANCE EXPENSES.

    Expenses incurred by an officer or director (acting in his capacity as such)
in defending a Proceeding shall be paid by the Corporation in advance of the
final disposition of such Proceeding; PROVIDED, HOWEVER, that if required by the
Delaware Corporation Law, as amended, such Expenses shall be advanced only upon
delivery to the Corporation of an undertaking by or on behalf of such director
or officer to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the Corporation as authorized in this Article
or otherwise. Expenses incurred by employees or other agents of the Corporation
(or by the directors or officers not acting in their capacity as such, including
service with respect to employee benefit plans) may be advanced upon such terms
and conditions as the Board of Directors deems appropriate. Any obligation to
reimburse the Corporation for Expense advances shall be unsecured and no
interest shall be charged thereon.

SECTION 9.3  RIGHT OF CLAIMANT TO BRING SUIT.

    If a claim under Section 9.1 or 9.2 of this Article is not paid in full by
the Corporation within 30 days after a written claim has been received by the
Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expense
(including attorneys' fees) of prosecuting such claim. It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses
incurred in defending a Proceeding in advance of its final disposition where the
required undertaking has been tendered to the Corporation) that the claimant has
not met the standards of conduct that make it permissible under the Delaware
Corporation Law for the Corporation to indemnify the claimant for the amount
claimed. The burden of proving such a defense shall be on the Corporation.
Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant is
proper under the circumstances because he has met the applicable standard of
conduct set forth in the Delaware Corporation Law, nor an actual determination
by the Corporation (including its Board of Directors, independent legal counsel,
or its stockholders) that the claimant had not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

SECTION 9.4  PROVISIONS NONEXCLUSIVE.

    The rights conferred on any person by this Article shall not be exclusive of
any other rights that such person may have or hereafter acquire under any
statute, provision of the Restated Certificate of Incorporation, agreement, vote
of stockholders or disinterested directors, or otherwise, both as to action in
an official capacity and as to action in another capacity while holding such
office. To the extent that any provision of the Restated Certificate of
Incorporation, agreement, or vote of the stockholders or disinterested directors
is inconsistent with these Bylaws, the provision, agreement, or vote shall take
precedence.

SECTION 9.5  AUTHORITY TO INSURE.

    The Corporation may purchase and maintain insurance to protect itself and
any director, officer, employee or other agent (collectively, an "Agent")
against any Expense, whether or not the Corporation would have the power to
indemnify the Agent against such Expense under applicable law or the provisions
of this Article.

SECTION 9.6  SURVIVAL OF RIGHTS.

    The rights provided by this Article shall continue as to a person who has
ceased to be an Agent and shall inure to the benefit of the heirs, executors,
and administrators of such a person.

SECTION 9.7  EFFECT OF AMENDMENT.

    Any amendment, repeal, or modification of this Article shall not adversely
affect any right or protection of any Agent existing at the time of such
amendment, repeal, or modification.

SECTION 9.8  SUBROGATION.

    In the event of payment under this Article, the Corporation shall be
subrogated to the extent of such payment to all of the rights of recovery of the
Agent, who shall execute all papers required and shall do everything that may be
necessary to secure such rights, including the execution of such documents
necessary to enable the Corporation effectively to bring suit to enforce such
rights.

SECTION 9.9  NO DUPLICATION OF PAYMENTS.

    The Corporation shall not be liable under this Article to make any payment
in connection with any claim made against the Agent to the extent the Agent has
otherwise actually received payment (under any insurance policy, agreement,
vote, or otherwise) of the amounts otherwise indemnifiable hereunder.

                                   ARTICLE X
                                    NOTICES

given to any stockholder, the same shall be given in writing, timely and duly
deposited in the United States Mail, postage prepaid, and addressed to his last
known post office address as shown by the stock record of the Corporation or its
transfer agent. Any notice required to be given to any director may be given by
the method hereinabove stated, or by telegram or other means of electronic
transmission, except that such notice other than one which is delivered
personally, shall be sent to such address or (in the case of facsimile
telecommunication or other means of electronic transmission) facsimile telephone
number or other relevant transmission instructions as such director shall have
filed in writing with the Secretary of the Corporation, or, in the absence of
such filing, to the last known post office address of such director. If no
address of a stockholder or director be known, such notice may be sent to the
office of the Corporation required to be maintained pursuant to Section 1.1 of
Article I hereof. An affidavit of

                                     D-2-18
<PAGE>
mailing, executed by a duly authorized and competent employee of the Corporation
or its transfer agent appointed with respect to the class of stock affected,
specifying the name and address or the names and addresses of the stockholder or
stockholders, director or directors, to whom any such notice or notices was or
were given, and the time and method of giving the same, shall be conclusive
evidence of the statements therein contained. All notices given by mail, as
above provided, shall be deemed to have been given as at the time of mailing and
all notices given by telegram or other means of electronic transmission shall be
deemed to have been given as at the sending time recorded by the telegraph
company or other electronic transmission equipment operator transmitting the
same. It shall not be necessary that the same method of giving be employed in
respect of all directors, but one permissible method may be employed in respect
of any one or more, and any other permissible method or methods may be employed
in respect of any other or others. The period or limitation of time within which
any stockholder may exercise any option or right, or enjoy any privilege or
benefit, or be required to act, or within which any director may exercise any
power or right, or enjoy any privilege, pursuant to any notice sent him in the
manner above provided, shall not be affected or extended in any manner by the
failure of such a stockholder such director to receive such notice. Whenever any
notice is required to be given under the provisions of the statutes or of the
Restated Certificate of Incorporation, or of these Bylaws, a waiver thereof in
writing signed by the person or persons entitled to said notice, whether before
or after the time stated therein, shall be deemed equivalent thereto. Whenever
notice is required to be given, under any provision of law or of the Restated
Certificate of Incorporation or Bylaws of the Corporation, to any person with
whom communication is unlawful, the giving of such notice to such person shall
not be required and there shall be no duty to apply to any governmental
authority or agency for a license or permit to give such notice to such person.
Any action or meeting which shall be taken or held without notice to any such
person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given.

                                   AMENDMENTS

number of Shares which may be issued pursuant to Awards initially shall be
13,500,000 Shares, and commencing with the first business day of each calendar
year thereafter beginning with 2001, such maximum aggregate number of Shares
shall be increased to a number that, when added to Shares with respect to which
Awards were previously authorized and are as yet unissued, equals thirty percent
(30%) of the number of outstanding shares of Equity Securities as of December 31
of the immediately preceding calendar year. Notwithstanding the foregoing,
subject to the provisions of Section 10, below, the maximum aggregate number of
Shares available for grant of Incentive Stock Options shall be 13,500,000
Shares, and such number shall not be subject to annual adjustment as described
above. The Shares to be issued pursuant to Awards may be authorized, but
unissued, or reacquired Common Stock.

    4.  ADMINISTRATION OF THE PLAN.

    (a) PLAN ADMINISTRATOR.

        (i) ADMINISTRATION WITH RESPECT TO DIRECTORS AND OFFICERS. With respect
    to grants of Awards to Directors or Employees who are also Officers or
    Directors of the Company, the Plan shall be administered by (A) the Board or
    (B) a Committee designated by the Board, which Committee shall be
    constituted in such a manner as to satisfy the Applicable Laws and to permit
    such grants and related transactions under the Plan to be exempt from
    Section 16(b) of the Exchange Act in

                                      E-5
<PAGE>
    accordance with Rule 16b-3. Once appointed, such Committee shall continue to
    serve in its designated capacity until otherwise directed by the Board.

        (ii) ADMINISTRATION WITH RESPECT TO CONSULTANTS AND OTHER EMPLOYEES.
    With respect to grants of Awards to Employees or Consultants who are neither
    Directors nor Officers of the Company, the Plan shall be administered by (A)
    the Board or (B) a Committee designated by the Board, which Committee shall
    be constituted in such a manner as to satisfy the Applicable Laws. Once
    appointed, such Committee shall continue to serve in its designated capacity
    until otherwise directed by the Board. The Board may authorize one or more
    Officers to grant such Awards and may limit such authority as the Board
    determines from time to time.

        (iii) ADMINISTRATION WITH RESPECT TO COVERED EMPLOYEES. Notwithstanding
    the foregoing, grants of Awards to any Covered Employee, or any other
    Employee whom the Administrator determines is likely to become a Covered
    Employee during the term of the Award, and that are intended to qualify as
    Performance-Based Compensation shall be made only by a Committee (or
    subcommittee of a Committee) which is comprised solely of two or more
    Directors eligible to serve on a committee making Awards qualifying as
    Performance-Based Compensation. In the case of such Awards granted to
    Covered Employees, references to the "Administrator" or to a "Committee"
    shall be deemed to be references to such Committee or subcommittee.

        (iv) ADMINISTRATION ERRORS. In the event an Award is granted in a manner
    inconsistent with the provisions of this subsection (a), such Award shall be
    presumptively valid as of its grant date to the extent permitted by the
    Applicable Laws.

    (b) POWERS OF THE ADMINISTRATOR. Subject to Applicable Laws and the
provisions of the Plan (including any other powers given to the Administrator
hereunder), and except as otherwise provided by the Board, the Administrator
shall have the authority, in its discretion:

        (i) to select the Employees, Directors and Consultants to whom Awards
    may be granted from time to time hereunder;

        (ii) to determine whether and to what extent Awards are granted
    hereunder;

       (iii) to determine the number of Shares or the amount of other
    consideration to be covered by each Award granted hereunder;

        (iv) to approve forms of Award Agreements for use under the Plan;

        (v) to determine the terms and conditions of any Award granted
    hereunder;

        (vi) to amend the terms of any outstanding Award granted under the Plan,
    provided that any amendment that would adversely affect the Grantee's rights
    under an outstanding Award shall not be made without the Grantee's written
    consent;

       (vii) to construe and interpret the terms of the Plan and Awards granted
    pursuant to the Plan, including without limitation, any notice of Award or
    Award Agreement, granted pursuant to the Plan;

      (viii) to establish additional terms, conditions, rules or procedures to
    accommodate the rules or laws of applicable foreign jurisdictions and to
    afford Grantees favorable treatment under such laws; provided, however, that
    no Award shall be granted under any such additional terms, conditions, rules
    or procedures with terms or conditions which are inconsistent with the
    provisions of the Plan; and

        (ix) to take such other action, not inconsistent with the terms of the
    Plan, as the Administrator deems appropriate.

                                      E-6
<PAGE>
    5.  ELIGIBILITY.  Awards other than Incentive Stock Options may be granted
to Employees, Directors and Consultants. Incentive Stock Options may be granted
only to Employees of the Company, a Parent or a Subsidiary. An Employee,
Director or Consultant who has been granted an Award may, if otherwise eligible,
be granted additional Awards. Awards may be granted to such Employees, Directors
or Consultants who are residing in foreign jurisdictions as the Administrator
may determine from time to time.

    6.  TERMS AND CONDITIONS OF AWARDS.

        (a) TYPE OF AWARDS. The Administrator is authorized under the Plan to
    award any type of arrangement to an Employee, Director or Consultant that is
    not inconsistent with the provisions of the Plan and that by its terms
    involves or might involve the issuance of (i) Shares, (ii) an Option, a SAR
    or similar right with a fixed or variable price related to the Fair Market
    Value of the Shares and with an exercise or conversion privilege related to
    the passage of time, the occurrence of one or more events, or the
    satisfaction of performance criteria or other conditions, or (iii) any other
    security with the value derived from the value of the Shares. Such awards
    include, without limitation, Options, SARs, sales or bonuses of Restricted
    Stock, Dividend Equivalent Rights, Performance Units or Performance Shares,
    and an Award may consist of one such security or benefit, or two (2) or more
    of them in any combination or alternative.

        (b) DESIGNATION OF AWARD. Each Award shall be designated in the Award
    Agreement. In the case of an Option, the Option shall be designated as
    either an Incentive Stock Option or a Non-Qualified Stock Option. However,
    notwithstanding such designation, to the extent that the aggregate Fair
    Market Value of Shares subject to Options designated as Incentive Stock
    Options which become exercisable for the first time by a Grantee during any
    calendar year (under all plans of the Company or any Parent or Subsidiary)
    exceeds $100,000, such excess Options, to the extent of the Shares covered
    thereby in excess of the foregoing limitation, shall be treated as Non-
    Qualified Stock Options. For this purpose, Incentive Stock Options shall be
    taken into account in the order in which they were granted, and the Fair
    Market Value of the Shares shall be determined as of the date the Option
    with respect to such Shares is granted.

        (c) CONDITIONS OF AWARD. Subject to the terms of the Plan, the
    Administrator shall determine the provisions, terms, and conditions of each
    Award including, but not limited to, the Award vesting schedule, repurchase
    provisions, rights of first refusal, forfeiture provisions, form of payment
    (cash, Shares, or other consideration) upon settlement of the Award, payment
    contingencies, and satisfaction of any performance criteria. The performance
    criteria established by the Administrator may be based on any one of, or
    combination of, increase in share price, earnings per share, total
    stockholder return, return on equity, return on assets, return on
    investment, net operating income, cash flow, revenue, economic value added
    and sales, in each case as applied to an individual, the Company or a
    subsidiary, division, business unit, or department thereof. Partial
    achievement of the specified criteria may result in a payment or vesting
    corresponding to the degree of achievement as specified in the Award
    Agreement.

        (d) ACQUISITIONS AND OTHER TRANSACTIONS. The Administrator may issue
    Awards under the Plan in settlement, assumption or substitution for,
    outstanding awards or obligations to grant future awards in connection with
    the Company or a Related Entity acquiring another entity, an interest in
    another entity or an additional interest in a Related Entity whether by
    merger, stock purchase, asset purchase or other form of transaction.

        (e) DEFERRAL OF AWARD PAYMENT. The Administrator may establish one or
    more programs under the Plan to permit selected Grantees the opportunity to
    elect to defer receipt of consideration upon exercise of an Award,
    satisfaction of performance criteria, or other event that absent the
    election would entitle the Grantee to payment or receipt of Shares or other
    consideration under an Award. The Administrator may establish the election
    procedures, the timing of such elections,

                                      E-7
<PAGE>
    the mechanisms for payments of, and accrual of interest or other earnings,
    if any, on amounts, Shares or other consideration so deferred, and such
    other terms, conditions, rules and procedures that the Administrator deems
    advisable for the administration of any such deferral program.

        (f) AWARD EXCHANGE PROGRAMS. The Administrator may establish one or more
    programs under the Plan to permit selected Grantees to exchange an Award
    under the Plan for one or more other types of Awards under the Plan on such
    terms and conditions as determined by the Administrator from time to time.

        (g) SEPARATE PROGRAMS. The Administrator may establish one or more
    separate programs under the Plan for the purpose of issuing particular forms
    of Awards to one or more classes of Grantees on such terms and conditions as
    determined by the Administrator from time to time.

        (h) INDIVIDUAL OPTION AND SAR LIMIT. The maximum number of Shares with
    respect to which Options and SARs may be granted to any Employee in any
    fiscal year of the Company shall be 1,000,000 Shares. The foregoing
    limitation shall be adjusted proportionately in connection with any change
    in the Company's capitalization pursuant to Section 10, below. To the extent
    required by Section 162(m) of the Code or the regulations thereunder, in
    applying the foregoing limitation with respect to an Employee, if any Option
    or SAR is canceled, the canceled Option or SAR shall continue to count
    against the maximum number of Shares with respect to which Options and SARs
    may be granted to the Employee. For this purpose, the repricing of an Option
    (or in the case of a SAR, the base amount on which the stock appreciation is
    calculated is reduced to reflect a reduction in the Fair Market Value of the
    Common Stock) shall be treated as the cancellation of the existing Option or
    SAR and the grant of a new Option or SAR.

        (i) EARLY EXERCISE. The Award Agreement may, but need not, include a
    provision whereby the Grantee may elect at any time while an Employee,
    Director or Consultant to exercise any part or all of the Award prior to
    full vesting of the Award. Any unvested Shares received pursuant to such
    exercise may be subject to a repurchase right in favor of the Company or a
    Related Entity or to any other restriction the Administrator determines to
    be appropriate.

        (j) TERM OF AWARD. The term of each Award shall be the term stated in
    the Award Agreement, provided, however, that the term of an Incentive Stock
    Option shall be no more than ten (10) years from the date of grant thereof.
    However, in the case of an Incentive Stock Option granted to a Grantee who,
    at the time the Option is granted, owns stock representing more than ten
    percent (10%) of the voting power of all classes of stock of the Company or
    any Parent or Subsidiary, the term of the Incentive Stock Option shall be
    five (5) years from the date of grant thereof or such shorter term as may be
    provided in the Award Agreement.

        (k) TRANSFERABILITY OF AWARDS. Incentive Stock Options may not be sold,
    pledged, assigned, hypothecated, transferred, or disposed of in any manner
    other than by will or by the laws of descent or distribution and may be
    exercised, during the lifetime of the Grantee, only by the Grantee;
    provided, however, that the Grantee may designate a beneficiary of the
    Grantee's Incentive Stock Option in the event of the Grantee's death on a
    beneficiary designation form provided by the Administrator. Other Awards may
    be transferred by gift or through a domestic relations order to members of
    the Grantee's Immediate Family to the extent provided in the Award Agreement
    or in the manner and to the extent determined by the Administrator.

        (l) TIME OF GRANTING AWARDS. The date of grant of an Award shall for all
    purposes be the date on which the Administrator makes the determination to
    grant such Award, or such other date as is determined by the Administrator.
    Notice of the grant determination shall be given to each Employee, Director
    or Consultant to whom an Award is so granted within a reasonable time after
    the date of such grant.

    7.  AWARD EXERCISE OR PURCHASE PRICE, CONSIDERATION, AND TAXES.

    (a) EXERCISE OR PURCHASE PRICE. The exercise or purchase price, if any, for
an Award shall be as follows:

        (i) In the case of an Incentive Stock Option:

           (A) granted to an Employee who, at the time of the grant of such
       Incentive Stock Option owns stock representing more than ten percent
       (10%) of the voting power of all classes of stock of the Company or any
       Parent or Subsidiary, the per Share exercise price shall be not less than
       one hundred ten percent (110%) of the Fair Market Value per Share on the
       date of grant; or

           (B) granted to any Employee other than an Employee described in the
       preceding paragraph, the per Share exercise price shall be not less than
       one hundred percent (100%) of the Fair Market Value per Share on the date
       of grant.

        (ii) In the case of a Non-Qualified Stock Option, the per Share exercise
    price shall be not less than eighty-five percent (85%) of the Fair Market
    Value per Share on the date of grant unless otherwise determined by the
    Administrator.

       (iii) In the case of Awards intended to qualify as Performance-Based
    Compensation, the exercise or purchase price, if any, shall be not less than
    one hundred percent (100%) of the Fair Market Value per Share on the date of
    grant.

        (iv) In the case of other Awards, such price as is determined by the
    Administrator.

        (v) Notwithstanding the foregoing provisions of this Section 7(a), in
    the case of an Award issued pursuant to Section 6(d), above, the exercise or
    purchase price for the Award shall be determined in accordance with the
    principles of Section 424(a) of the Code.

    (b) CONSIDERATION. Subject to Applicable Laws, the consideration to be paid
for the Shares to be issued upon exercise or purchase of an Award including the
method of payment, shall be determined by the Administrator (and, in the case of
an Incentive Stock Option, shall be determined at the time of grant). In
addition to any other types of consideration the Administrator may determine,
the Administrator is authorized to accept as consideration for Shares issued
under the Plan the following, provided that the portion of the consideration
equal to the par value of the Shares must be paid in cash or other legal
consideration permitted by the Delaware General Corporation Law:

            (i) cash;

            (ii) check;

           (iii) delivery of Grantee's promissory note with such recourse,
       interest, security, and redemption provisions as the Administrator
       determines as appropriate;

            (iv) surrender of Shares or delivery of a properly executed form of
       attestation of ownership of Shares as the Administrator may require
       (including withholding of Shares otherwise deliverable upon exercise of
       the Award) which have a Fair Market Value on the date of surrender or
       attestation equal to the aggregate exercise price of the Shares as to
       which said Award shall be exercised (but only to the extent that such
       exercise of the Award would not result in an accounting compensation
       charge with respect to the Shares used to pay the exercise price unless
       otherwise determined by the Administrator);

            (v) with respect to Options, payment through a broker-dealer sale
       and remittance procedure pursuant to which the Grantee (A) shall provide
       written instructions to a Company designated brokerage firm to effect the
       immediate sale of some or all of the purchased Shares and remit to the
       Company, out of the sale proceeds available on the settlement date,

                                      E-9
<PAGE>
       sufficient funds to cover the aggregate exercise price payable for the
       purchased Shares and (B) shall provide written directives to the Company
       to deliver the certificates for the purchased Shares directly to such
       brokerage firm in order to complete the sale transaction; or

            (vi) any combination of the foregoing methods of payment.

    (c) TAXES. No Shares shall be delivered under the Plan to any Grantee or
other person until such Grantee or other person has made arrangements acceptable
to the Administrator for the satisfaction of any foreign, federal, state, or
local income and employment tax withholding obligations, including, without
limitation, obligations incident to the receipt of Shares or the disqualifying
disposition of Shares received on exercise of an Incentive Stock Option. Upon
exercise of an Award, the Company shall withhold or collect from Grantee an
amount sufficient to satisfy such tax obligations.

    8.  EXERCISE OF AWARD.

    (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER.

        (i) Any Award granted hereunder shall be exercisable at such times and
    under such conditions as determined by the Administrator under the terms of
    the Plan and specified in the Award Agreement.

        (ii) An Award shall be deemed to be exercised when written notice of
    such exercise has been given to the Company in accordance with the terms of
    the Award by the person entitled to exercise the Award and full payment for
    the Shares with respect to which the Award is exercised, including, to the
    extent selected, use of the broker-dealer sale and remittance procedure to
    pay the purchase price as provided in Section 7(b)(v). Until the issuance
    (as evidenced by the appropriate entry on the books of the Company or of a
    duly authorized transfer agent of the Company) of the stock certificate
    evidencing such Shares, no right to vote or receive dividends or any other
    rights as a stockholder shall exist with respect to Shares subject to an
    Award, notwithstanding the exercise of an Option or other Award. The Company
    shall issue (or cause to be issued) such stock certificate promptly upon
    exercise of the Award. No adjustment will be made for a dividend or other
    right for which the record date is prior to the date the stock certificate
    is issued, except as provided in the Award Agreement or Section 10, below.

    (b) EXERCISE OF AWARD FOLLOWING TERMINATION OF CONTINUOUS SERVICE.

        (i) An Award may not be exercised after the termination date of such
    Award set forth in the Award Agreement and may be exercised following the
    termination of a Grantee's Continuous Service only to the extent provided in
    the Award Agreement.

        (ii) Where the Award Agreement permits a Grantee to exercise an Award
    following the termination of the Grantee's Continuous Service for a
    specified period, the Award shall terminate to the extent not exercised on
    the last day of the specified period or the last day of the original term of
    the Award, whichever occurs first.

       (iii) Any Award designated as an Incentive Stock Option to the extent not
    exercised within the time permitted by law for the exercise of Incentive
    Stock Options following the termination of a Grantee's Continuous Service
    shall convert automatically to a Non-Qualified Stock Option and thereafter
    shall be exercisable as such to the extent exercisable by its terms for the
    period specified in the Award Agreement.

    9.  CONDITIONS UPON ISSUANCE OF SHARES.

    (a) Shares shall not be issued pursuant to the exercise of an Award unless
the exercise of such Award and the issuance and delivery of such Shares pursuant
thereto shall comply with all Applicable Laws, and shall be further subject to
the approval of counsel for the Company with respect to such compliance.

                                      E-10
<PAGE>
    (b) As a condition to the exercise of an Award, the Company may require the
person exercising such Award to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any Applicable
Laws.

    10.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.  Subject to any required
action by the stockholders of the Company, the number of Shares covered by each
outstanding Award, and the number of Shares which have been authorized for
issuance under the Plan but as to which no Awards have yet been granted or which
have been returned to the Plan, the exercise or purchase price of each such
outstanding Award, the maximum number of Shares with respect to which Options
and SARs may be granted to any Employee in any fiscal year of the Company, as
well as any other terms that the Administrator determines require adjustment
shall be proportionately adjusted for (i) any increase or decrease in the number
of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Shares, or similar event
affecting the Shares, (ii) any other increase or decrease in the number of
issued Shares effected without receipt of consideration by the Company, or (iii)
as the Administrator may determine in its discretion, any other transaction with
respect to Common Stock to which Section 424(a) of the Code applies or any
similar transaction; provided, however that conversion of any convertible
securities of the Company shall not be deemed to have been "effected without
receipt of consideration." Such adjustment shall be made by the Administrator
and its determination shall be final, binding and conclusive. Except as the
Administrator determines, no issuance by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason hereof shall be made with respect to, the
number or price of Shares subject to an Award.

    11.  CORPORATE TRANSACTIONS/CHANGES IN CONTROL/RELATED ENTITY
DISPOSITIONS.  Except as may be provided in an Award Agreement:

        (a) In the event of any Change in Control, each Award which is at the
    time outstanding under the Plan automatically shall have its vesting
    accelerated by 12 months (such that (1) any Award that is not yet vested but
    was otherwise scheduled to become vested within 12 months instead becomes
    vested and exercisable on the effective date of the Change in Control, and
    (2) any Award that is not yet vested and was otherwise scheduled to become
    vested on a date that is more than 12 months after the Change in Control
    instead become fully vested and exercisable on a date that is 12 months
    earlier than the date provided for in by the terms of the Award). Each such
    Award that becomes vested and exercisable on the effective date of the
    Change in Control shall also be released from any restrictions on transfer
    (other than transfer restrictions applicable to Incentive Stock Options) and
    repurchase or forfeiture rights, immediately prior to the specified
    effective date of such Change in Control, for all of the Shares at the time
    represented by the vested portion of such Award. Effective upon the
    consummation of the Change in Control, all outstanding Awards under the Plan
    shall terminate. However, an outstanding Award under the Plan shall not so
    terminate if and to the extent: (i) such Award is, in connection with the
    Change in Control, either assumed by the successor corporation or Parent
    thereof or replaced with a comparable Award with respect to shares of the
    capital stock of the successor corporation or Parent thereof, or (ii) such
    Award is to be replaced with a cash incentive program of the successor
    corporation which preserves the compensation element of such Award existing
    at the time of the Change in Control and provides for subsequent payout in
    accordance with the same vesting schedule applicable to such Award, or (iii)
    such Award is purchased for cash in an amount equal to the fair value of the
    Award, as reasonably determined by the Administrator, as of the date of the
    Change in Control. The determination of Award comparability above shall be
    made by the Administrator.

        (b) Following a Change in Control and upon the termination of the
    Continuous Service of a Grantee if such Continuous Service is terminated by
    the Company or Related Entity or the

                                      E-11
<PAGE>
    successor employer corporation without Cause or voluntarily by the Grantee
    with Good Reason within twelve (12) months of a Change in Control, each
    Award of such Grantee which is at the time outstanding under the Plan (or
    the replacement Award or cash incentive program, if applicable)
    automatically shall become fully vested and exercisable and be released from
    any restrictions on transfer (other than transfer restrictions applicable to
    Incentive Stock Options) and repurchase or forfeiture rights, immediately
    upon the termination of such Continuous Service.

        (c) Effective upon the consummation of a Related Entity Disposition, for
    purposes of the Plan and all Awards, the Continuous Service of each Grantee
    who is at the time engaged primarily in service to the Related Entity
    involved in such Related Entity Disposition shall be deemed to terminate and
    each Award of such Grantee which is at the time outstanding under the Plan
    automatically shall become fully vested and exercisable and be released from
    any restrictions on transfer (other than transfer restrictions applicable to
    Incentive Stock Options) and repurchase or forfeiture rights for all of the
    Shares at the time represented by such Award and be exercisable in
    accordance with the terms of the Award Agreement evidencing such Award.
    However, such Continuous Service shall be not be deemed to terminate if such
    Award is, in connection with the Related Entity Disposition, assumed by the
    successor entity or its Parent. In addition, such Continuous Service shall
    not be deemed to terminate and an outstanding Award under the Plan shall not
    so fully vest and be exercisable and released from such limitations if and
    to the extent: (i) such Award is, in connection with the Related Entity
    Disposition, either to be assumed by the successor entity or its parent or
    to be replaced with a comparable Award with respect to interests in the
    successor entity or its parent or (ii) such Award is to be replaced with a
    cash incentive program of the successor entity which preserves the
    compensation element of such Award existing at the time of the Related
    Entity Disposition and provides for subsequent payout in accordance with the
    same vesting schedule applicable to such Award; provided, however, that such
    Award (if assumed), the replacement Award (if replaced), or the cash
    incentive program automatically shall become fully vested, exercisable and
    payable and be released from any restrictions on transfer (other than
    transfer restrictions applicable to Incentive Stock Options) and repurchase
    or forfeiture rights immediately upon termination of the Grantee's
    Continuous Service (substituting the successor employer entity for "Company
    or Related Entity" for the definition of "Continuous Service") if such
    Continuous Service is terminated by the successor entity without Cause or
    voluntarily by the Grantee with Good Reason within twelve (12) months of the
    Related Entity Disposition. The determination of Award comparability above
    shall be made by the Administrator.

    12.  EFFECTIVE DATE AND TERM OF PLAN.  The Plan shall become effective upon
the later to occur of its adoption by the Board or its approval by the
stockholders of Xoom.com, Inc. It shall continue in effect for a term of ten
(10) years unless sooner terminated.

    13.  AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN.

        (a) The Board may at any time amend, suspend or terminate the Plan. To
    the extent necessary to comply with Applicable Laws, the Company shall
    obtain stockholder approval of any Plan amendment in such a manner and to
    such a degree as required.

        (b) No Award may be granted during any suspension of the Plan or after
    termination of the Plan.

        (c) Any amendment, suspension or termination of the Plan (including
    termination of the Plan under Section 12, above) shall not affect Awards
    already granted, and such Awards shall remain in full force and effect as if
    the Plan had not been amended, suspended or terminated, unless mutually
    agreed otherwise between the Grantee and the Administrator, which agreement
    must be in writing and signed by the Grantee and the Company.

                                      E-12
<PAGE>
    14.  RESERVATION OF SHARES.

        (a) The Company, during the term of the Plan, will at all times reserve
    and keep available such number of Shares as shall be sufficient to satisfy
    the requirements of the Plan.

        (b) The inability of the Company to obtain authority from any regulatory
    body having jurisdiction, which authority is deemed by the Company's counsel
    to be necessary to the lawful issuance and sale of any Shares hereunder,
    shall relieve the Company of any liability in respect of the failure to
    issue or sell such Shares as to which such requisite authority shall not
    have been obtained.

    15.  NO EFFECT ON TERMS OF EMPLOYMENT/CONSULTING RELATIONSHIP.  The Plan
shall not confer upon any Grantee any right with respect to the Grantee's
Continuous Service, nor shall it interfere in any way with his or her right or
the Company's right to terminate the Grantee's Continuous Service at any time,
with or without cause.

    16.  NO EFFECT ON RETIREMENT AND OTHER BENEFIT PLANS.  Except as
specifically provided in a retirement or other benefit plan of the Company or a
Related Entity, Awards shall not be deemed compensation for purposes of
computing benefits or contributions under any retirement plan of the Company or
a Related Entity, and shall not affect any benefits under any other benefit plan
of any kind or any benefit plan subsequently instituted under which the
availability or amount of benefits is related to level of compensation. The Plan
is not a "Retirement Plan" or "Welfare Plan" under the Employee Retirement
Income Security Act of 1974, as amended.

APPROVAL BY EASDAQ


ADMISSION TO TRADING ON EASDAQ


    NBCi has applied for admission of its Class A common stock to trading on
EASDAQ under the symbol "NBCI". The Class A common stock is expected to begin
trading on EASDAQ on the date after the closing of the contribution agreement,
which is expected to occur in November 1999. Admission to EASDAQ is subject to
certain adequacy and liquidity requirements determined by the EASDAQ Market
Authority. Companies whose securities are traded on EASDAQ are required to
publish relevant financial and other information regularly and to keep the
public informed of all events likely to affect the market price of their
securities. Price sensitive information is made available to investors in Europe
through the EASDAQ Reuters Regulatory Company Reporting System and international
information vendors. In case of any doubt about the contents or the meaning of
the information contained in this document, an authorized or professional person
specializing in advising on the acquisition of financial instruments should be
consulted. A copy of NBCi's restated certificate of incorporation will be
available for viewing at EASDAQ and is included in the proxy statement/
prospectus as Appendix D-1.


    NBCi's Class A common stock has the following identification number:

                          CUSIP 62873D  ISIN US 62873D1054

POSSIBILITY OF SHARE REPURCHASES


    NBCi's restated certificate of incorporation, amended and restated bylaws
and the Delaware General Corporate Law do not prohibit NBCi from repurchasing or
otherwise acquiring outstanding shares of its common stock, and, accordingly,
NBCi may exercise its right to repurchase common stock, subject to applicable
law. Upon the issuance of the Class A common stock in the manner set forth in
the proxy statement/prospectus, such shares will be freely transferable within
the European Union, and be fully-paid and nonassessable.


ADDITIONAL INFORMATION REGARDING OUR CONSOLIDATED FINANCIAL STATEMENTS

    The financial statements set forth in the proxy statement/prospectus have
been prepared in accordance with US GAAP.

PERSONS RESPONSIBLE FOR THE PROXY STATEMENT/PROSPECTUS AND DECLARATION

contents of this proxy statement/prospectus. To the best of NBCi's knowledge and
belief, the information contained in this proxy statement/prospectus is
factually accurate in all material respects and is not misleading and there is

misleading or be likely to affect the import of any information in the proxy

                            SETTLEMENT AND CLEARANCE


    The following summarizes NBCi's understanding of the operation of the
clearing system which will be in place. Persons proposing to trade the Class A
common stock on EASDAQ should inform themselves about the costs of such trading.



    Transactions in the Class A common stock executed in the United States
generally will be settled by book-entry through financial institutions that are
participants in DTC.


    DTC is a limited-purpose trust company that was created to hold securities
for its participating organizations (collectively, "DTC Participants") and to
facilitate the clearance and settlement of transactions in such securities
between participants through electronic book-entry changes in accounts of DTC
Participants. DTC Participants include securities brokers and dealers, banks and
trust companies, clearing corporations and certain other organizations. Access
to DTC's system is also available to other entities such as banks, brokers,
dealers and trust companies (collectively, "DTC Indirect Participants") that
clear through or maintain a custodial relationship with a DTC Participant,
either directly or indirectly. Persons who are DTC Participants may beneficially
own securities held by or on behalf of DTC only through DTC Participants or DTC
Indirect Participants.

    NBCi's Class A common stock is expected to be quoted on EASDAQ in USD.
Transactions in the common stock on EASDAQ will be settled in USD or any other
Euroclear or Cedelbank eligible currency through the Euroclear or Cedelbank
Systems. Investors in the Class A common stock on EASDAQ must have a securities
account with a financial institution which directly or indirectly has access to
Euroclear or Cedelbank. Euroclear and Cedelbank are DTC Indirect Participants.

    Euroclear and Cedelbank hold securities and book-entry interests in
securities for their direct participants, which include banks, securities
brokers and dealers, other professional intermediaries and foreign depositories
and facilitate the clearance and settlement of securities transactions between
their respective participants, and between their participants and participants
of certain other securities intermediaries, including DTC, through electronic
book-entry changes in accounts of such participants or other securities
intermediaries.

    Euroclear and Cedelbank provide their respective participants, among other
things, with safekeeping, administration, clearance and settlement, securities
lending and borrowing, and related services. Euroclear and Cedelbank
participants are investment banks, securities brokers and dealers, banks,
central banks, supranationals, custodians, investment managers, corporations,
trust companies and certain other organizations and include certain of the
underwriters.

        We have examined the Registration Statement on Form S-4 filed by you
with the Securities and Exchange Commission (the "Registration Statement")
relating to the registration under the Securities Act of 1933, as amended, of
20,120,409 shares of your Class A common stock, $0.0001 par value (the "Stock").

        As your counsel, we have examined the proceedings taken and are familiar
with the proceedings proposed to be taken by you in connection with the issuance
of the Stock pursuant to the transactions set forth and described in the
Registration Statement.

        Based upon and subject to the foregoing, it is our opinion that the

Statement and further consent to the use of our name whenever appearing in the
Registration Statement and any amendments thereto. In giving this consent, we do
not thereby admit that we are in the category of persons whose consent is

          The principal of this Note shall not bear interest except in the case
of a default in the payment of principal upon acceleration, upon redemption or

not so paid on demand shall bear interest at the Yield to Maturity, which shall
accrue from the date of such demand for payment to the date payment of such
interest has been made or duly provided for, and such interest shall also be
payable on demand.  As used herein, the term "Issue Price" means the principal

thereof to Payee.  Maker may pay the redemption price in cash, Common Stock (as

     conversion right pursuant to this Section 2(a), Maker shall promptly
     deliver the Conversion Shares registered in the name of Payee.

          (b) ADJUSTMENTS.  The conversion rights set forth are subject to
     adjustment as provided below.

          (i)   STOCK SPLITS, STOCK DIVIDENDS AND COMBINATIONS.  If Maker shall
          at any time subdivide the outstanding shares of Common Stock or shall
          issue a stock dividend with respect to the Common Stock, then the
          number of shares of Common Stock for which this Note is convertible
          immediately prior to that subdivision shall be proportionately
          increased, and if Maker shall at any time combine the outstanding
          shares of Common Stock, then the number of shares of Common Stock for
          which this Note is exercisable immediately prior to that combination
          shall be proportionately reduced.  Any adjustment under this Section
          2(b)(i) shall become effective at the close of business on the date
          the subdivision, stock dividend or combination becomes effective.

                                                                          3

          (ii)  RECLASSIFICATION, EXCHANGE, SUBSTITUTION AND IN-KIND
          DISTRIBUTION.  If the Common Stock issuable on conversion of this Note
          shall be changed into the same or a different number of shares of any
          other class or classes of stock, whether by capital reorganization,
          reclassification, or otherwise (other than a subdivision or
          combination of shares provided for above) or upon the payment of a
          dividend in cash, securities or property other than Common Stock, then
          Payee shall, upon conversion of this Note, be entitled to receive, in
          lieu of the Common Stock that Payee would have become entitled to
          receive but for such change, that number of shares of such other class
          or classes of stock that is equivalent to the number of shares of
          Common Stock that Payee would have received had Payee converted this
          Note immediately prior to that change.  Following any
          reclassification, exchange, substitution or in-kind distribution,
          Maker shall promptly issue to Payee a new Note for such new securities
          or other property.  The new Note shall provide for adjustments which
          shall be nearly equivalent as may be reasonably practicable to the
          adjustments provided for in this Section 2(b) including, without
          limitation, adjustments to the number of securities or property
          issuable upon conversion of the new Note.  The provisions of this
          Section 2(b)(ii) shall similarly apply to successive
          reclassifications, exchanges, substitutions or other events and
          successive dividends.

          (iii) REORGANIZATIONS, MERGERS, CONSOLIDATIONS OR SALE OF ASSETS.  In
          case of any merger of Maker with or into another company (other than a
          merger with another company in which Maker is a continuing company and
          which does not result in any reclassification or change of outstanding
          securities issuable upon conversion of this Note), consolidation or in
          case of any sale of all or substantially all of the assets of Maker,
          Maker shall, as condition precedent to such transaction, execute a new
          Note or cause such successor or purchasing company, as the case may
          be, to execute a new Note, providing that Payee shall have the right
          to convert such new Note and upon such conversion to receive, in lieu
          of each share of Common Stock theretofore issuable upon conversion of
          this Note, the kind and amount of shares of stock, other securities,
          money and property issuable or payable, as the case may be, upon such
          merger, consolidation, sale of assets or other change to a holder of
          one share of Common Stock.  Such new Note shall provide for
          adjustments that shall be as nearly equivalent as may be reasonably
          practicable to the adjustments provided for in this Section 2(b).  The
          provisions of this Section 2(b)(iii) shall similarly apply to
          successive mergers, consolidations, sale of assets and other changes
          and transfers.

          (iv)  NOTICE OF ADJUSTMENTS.  Maker shall promptly give written notice
          of each adjustment or readjustment of the number of shares of Common
          Stock or other securities issuable upon conversion of this Note, by
          first class mail, postage prepaid, to the Payee at the Payee's address
          for notices in the Merger Agreement.  This notice shall state that
          adjustment or readjustment and show in reasonable detail the facts on
          which the adjustment or readjustment is based.  Maker further

<PAGE>
                                                                          5

          agrees to notify Payee in writing of a reorganization, merger or sale
          in accordance with Section 2(b)(iii) at least thirty (30) days prior
          to the effective date thereof.

          (v)   NO CHANGE NECESSARY.  The form of this Note need not be changed
          because of any adjustment in the number of shares of Common Stock
          issuable upon its conversion.  A Note issued after any adjustment on
          conversion or upon replacement may continue to express the same number
          of shares of Common Stock as are stated on this Note as initially
          issued, and such number of shares shall be considered to have been so
          changed as of the close of business on the date of adjustment.

          (vi)  RESERVATION OF STOCK.  Maker covenants that it will at all times
          reserve and keep available, for issuance upon conversion of this Note,
          such shares of its Common Stock from time to time issuable upon
          conversion of this Note, and if at any time the number of authorized
          but unissued shares of Common Stock shall not be sufficient to effect
          the conversion of this Note, Maker will take such corporate action as
          may, in the opinion of its counsel, be reasonably necessary to
          increase its authorized but unissued shares of Common Stock to such
          number of shares as shall be sufficient for such purpose.  Issuance of
          this Note shall constitute full authority to Maker's officers who are
          charged with the duty of executing stock certificates to execute and
          issue the necessary certificates for shares of Common Stock issuable
          upon the conversion of this Note.

          (vii) NOTICES OF RECORD DATE.  In the event Maker intends to declare a
          record date for the holders of Common Stock for the purpose of
          determining the holders thereof who are entitled to receive any
          dividend or other distribution, Maker shall mail to Payee of this Note
          at least ten days prior to the proposed record date specified therein,
          a notice specifying the date on which any such record is to be taken
          for the purpose of such dividend or distribution.

          (viii)    NO IMPAIRMENT.  Maker shall not, by amendment of its
          Certificate of Incorporation or through a reorganization, transfer of
          assets, consolidation, merger, dissolution, issue or sale of
          securities or any other voluntary action, avoid or seek to avoid the
          observance or performance of any of the terms to be observed or
          performed under this Note by Maker, but shall at all time in good
          faith assist in carrying out of all the provisions of this Section
          2(b) and in taking all such action as may be reasonably necessary or
          appropriate to protect Payee's rights under this Section 2(b) against
          impairment.

          (c) GOVERNANCE RIGHTS.  Upon conversion of this Note pursuant to
     Section 2(a), and conversion of the Zero Coupon Convertible Debenture due
     2006 representing up to $39,477,953 issued by Maker to NBC Multimedia,
     Inc., Payee shall have the right to elect one additional director to the
     Board of Directors of Maker pursuant to the Certificate of Incorporation of
     Maker.

has been duly executed and delivered on behalf of Maker; (b) this Note
constitutes a legal, valid and binding obligation of Maker enforceable against
it in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law); (c) the execution, delivery and performance of this Note, the borrowing
hereunder and the use of the proceeds thereof will not violate any material
requirement of law, any material contractual obligation of Maker or its
subsidiaries or any of their applicable charters, bylaws or similar documents;
and (d) no Event of Default (as defined below) has occurred and is continuing.

          4.  REPRESENTATIONS AND WARRANTIES OF PAYEE.  Payee hereby represents
and warrants to Maker that: (a) Payee is duly organized, validly existing and in
good standing under the laws of its jurisdiction of organization, has the full
power and authority, and the legal right, to make the loan to Maker evidenced by
this Note and has taken all necessary corporate action to authorize the making
of such loan, and this Note has been duly executed and delivered on behalf of
Payee; (b) Payee is an "accredited investor" within the meaning of Regulation D

thereof in violation of the Securities Act; (c) Payee understands and
acknowledges that this Note has not been registered under the Securities Act and

law, and that Maker is not required to register this Note; and (d) Payee has had
access to such financial and other information concerning Maker as it deemed
necessary in connection with the issuance of this Note.

          5. EVENTS OF DEFAULT.  An Event of Default occurs if:  (1) Maker
pursuant to or within the meaning of Title 11 of the U.S. Code or any similar
federal or state law for the relief of debtors (a "Bankruptcy Law"):  (a)
commences a voluntary case, (b) consents to the entry of an order for relief

<PAGE>
                                                                          6

Payee had exercised its rights under Section 2 immediately prior to such
Event of Default or (ii) either (A) in the event of a default pursuant to
(1), (2) or (3) above, the Amortized Face Amount or (B) in the event of a
default pursuant to (4) above, the principal amount due at the Stated
Maturity Date plus accrued interest thereon from the Stated Maturity Date at

Payee shall immediately become due and payable.  As used herein the term
"Change of Control" means any of the following: (i) a merger, consolidation
or other business combination or transaction to which a Maker is a party if
the shareholders of Maker immediately prior to the effective date of such
merger, consolidation or other business combination or transaction, do not

the total voting power of the surviving corporation or its parent immediately
following such merger, consolidation or other business combination or
transaction; (ii) any person or entity shall have beneficial ownership of 20%
or more of the outstanding shares of Class A Stock (as such term is defined
in Maker's Certificate of Incorporation) at a time when the holders of Common
Stock do not elect a majority of the Board of Directors of Maker; (iii) a
sale of all or substantially all of the consolidated assets of Maker to
another person or entity or (iv) a liquidation or dissolution of Maker.

          6. SUBORDINATION.  Payee agrees that payment of the principal of and
interest on this Note shall be subordinated in right of payment to the prior
payment in full of all Senior Debt at any time outstanding.  Notwithstanding the
immediately preceding sentence, such subordination shall not limit the payment
of principal of and interest on this Note in accordance with its terms unless,
at the time of such payment, there is a default in the payment of principal of
or interest on such Senior Debt, there exists any event which, with the giving
of notice or the passage of time, is reasonably likely to give rise to a default
under such Senior Debt, or in the event that a default under this Note has
caused a default under such Senior Debt.  The limitation on payments under this
Note shall continue until such time as the default on such Senior Debt has been
cured or waived.  The provisions of this paragraph are intended solely for the
purpose of defining the relative rights of the Payee of this Note, on the one
hand, and the holder of Senior Debt, on the other hand.  "Senior Debt" shall
mean (a) any and all liabilities of Maker recorded on the Maker's balance sheet
or in the footnotes thereto in accordance with GAAP (as defined below); (b) the
principal of, premium (if any), interest on, and other moneys due which arise

funds; (2) due to sellers or lessors of any real or personal property to Maker;
or (3) for reimbursement obligations with respect to letters of credit, except
in each case referred to in subclauses (1), (2) and (3) above, to the extent the
holder of such indebtedness otherwise agrees in writing; (c) any other
indebtedness of Maker, except to the extent that the holder of such indebtedness
otherwise agrees in writing; and (d) any debentures, notes or other evidence of
indebtedness issued in exchange for any of the foregoing indebtedness, or any

the American Institute of Certified Public Accountants and statements and

                                                                          7

          7. BUSINESS DAY.  If any payment or conversion shall be required by
the terms hereof to be made on a day that is not a Business Day (as defined
below), such payment or conversion shall be made on the immediately succeeding
Business Day.  For purposes hereof, "Business Day" shall mean a day other than a
Saturday, Sunday, holiday or other day on which commercial banks in the State of
New York are authorized or required by law to close.

          8.NO WAIVER.  No action or omission by Payee shall constitute a waiver
of any rights or remedies of Payee hereunder.  Such rights and remedies are
cumulative and not exclusive of any rights or remedies provided by law.

          9. AMENDMENT; ASSIGNMENT . The terms of this Note may be amended,
supplemented or modified only with the written consent of Maker and Payee.  This
Note shall be binding upon and inure to the benefit of Maker, Payee and their
respective successors and assigns, except that neither Payee nor Maker may
assign or transfer any of its rights or obligations under this Note without the
prior written consent of the other party.  In the event of any assignment or
transfer by Payee with the prior written consent of Maker, Maker shall, upon the

New York, New York, and, pursuant to Section 5-1401 of the General Obligations
Law of the State of New York, shall be governed by and construed and interpreted
in accordance with the laws of the State of New York applicable to contracts
fully performed in New York.  All judicial actions, suits or proceedings brought
against Maker or Payee with respect to its obligations, liabilities or any other
matter under or arising out of or in connection with this Note or for
recognition or enforcement of any judgment rendered in any such proceedings
shall be brought exclusively in any state or federal court located in the County
of New York.

          11.    MUTILATED, DESTROYED OR MISSING NOTES.  If this Note is
mutilated and surrendered to Maker or Maker receives evidence to its
satisfaction of the destruction, loss or theft of this Note, Maker shall issue a
replacement Note.  If required by Maker, an indemnity bond must be supplied by
Payee that is sufficient in the judgment of Maker to protect Maker from any loss
it may suffer if this Note is replaced.  Maker may charge for any expenses of
replacing this Note.

          IN WITNESS WHEREOF, Maker has caused this Note to be duly issued as of
the date first above written.

POSITION:     Following the closing of the proposed merger between Xoom.com and

              be $1.00 per pay period. Xoom.com acknowledges that until the
