                          DEREGISTRATION OF SECURITIES

      On August 18, 2000, RealNetworks, Inc. filed a registration statement on
Form S-3 (No. 333-44110) (the "Registration Statement") which registered 39,940
shares of its common stock for resale from time to time. The Form S-3 was
declared effective by the Commission on August 31, 2000.

      The Registration Statement was filed in order to register shares of the
RealNetworks' common stock issued to the former shareholders of Multipoint,
Inc., which was acquired by RealNetworks on July 20, 2000. Based on the records
of RealNetworks' transfer agent, the selling shareholders resold 39,541 of the
39,940 shares registered under the Registration Statement.

      In accordance with the undertaking contained in the registration statement
pursuant to item 512(a)(3) of Regulation S-K, RealNetworks respectfully requests
that the Commission remove from registration a total of 399 shares which remain
unsold under the Registration Statement. RealNetworks is requesting the removal
from registration of these shares as its obligation to maintain the
effectiveness of the Registration Statement pursuant to the registration rights
agreements between the Company and the former shareholders of Multipoint, Inc.
expired on November 29, 2000.

      Accordingly, RealNetworks hereby de-registers 399 shares of its common
stock registered pursuant to the Registration Statement remaining unsold
thereunder.
