Item 5.  Other Events.

          On June 11, 1999, the Company and National Broadcasting Company, Inc.
("NBC") entered into a Stock Purchase Agreement, pursuant to which, subject to
regulatory and other conditions, NBC will acquire 960,028 shares of common
stock, par value $0.0001 per share ("Common Stock") for $57.29 per share in
cash. Pursuant to the Stock Purchase Agreement, NBC agreed to vote all of the
shares it acquires pursuant to the Stock Purchase Agreement in favor of the
adoption of the Agreement and Plan of Contribution and Merger, dated as of May
9, 1999, among the Company and certain of the Company's subsidiaries, CNET, Inc.
and Snap! LLC and in favor of the approval of the Company's adoption of the
Amended Agreement (as defined below).

          On June 11, 1999, the Company and certain of its subsidiaries,
National Broadcasting Company, Inc. and certain of its affiliates entered into
an Amended and Restated Agreement and Plan of Contribution, Investment and
Merger (the "Amended Agreement") which amended and restated the Agreement and
Plan of Contribution, Investment and Merger, dated as of May 9, 1999, among the
same parties. Pursuant to the Amended Agreement, (A) each share of common stock
of NBC's subsidiary Neon Media Corporation will be exchanged for one share of
Class B common stock ("Class B Stock") of NBCi, which will result in the
issuance of 12,173,111 shares of Class B Stock as compared to 13,764,726 under
the original agreement; and (B) a subsidiary of NBC will receive 11,417,569
shares of Class B Stock in exchange for its ownership interests in SNAP! LLC
(including its options to purchase additional equity interests) which number is
unchanged from the original agreement. Thereafter, an affiliate of NBC will
purchase a $486,894,758 zero coupon convertible debenture due 2006 (the
"Convertible Note") of NBCi for certain assets and the assignment of an NBC
promissory note in the amount of $340 million (the "NBC Note") to NBCi as
compared to the assignment of the NBC Note and a cash payment of $30 million
under the original agreement. The NBC Note has a term of four years and will
bear interest at 5.4% per annum. The Convertible Note may be converted by the
holder thereof into 5,809,388 shares of Class B Stock, as compared to 4,651,493
shares under the original agreement, only after one year after its Issuance.

          The Company and Xoom also entered into a registration rights agreement
with respect to the common stock purchased pursuant to the Stock Purchase
Agreement, which rights terminate upon consummation of the Amended Agreement.

          The closing of the transactions contemplated by the Stock Purchase
Agreement is independent of the Amended Agreement and is subject to customary
closing conditions for a cash purchase of stock, primarily the expiration or
early termination of the 30-day waiting period imposed by the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended.

         The foregoing summary does not purport to be complete and is subject
to, and qualified in its entirety by reference to, the provisions of the
agreements which are filed as exhibits hereto.
