On August 6, 1997, Real Media, Inc. filed an opposition proceeding in the U.S.
Patent and Trademark Office challenging the application of Real Networks, Inc.
(f/k/a Progressive Network, Inc.) to register REAL MEDIA as a trademark for
"computer software which allows the viewing and transmitting of picture and/or
video and/or text segments and audio segments over global information networks
that transfer and disseminate a wide range of information." The use has been
limited to a naming protocol for its software architecture. In its Notice of
Opposition, Real Media has asserted that it has prior rights in the mark REAL
MEDIA in connection with its on-line advertising services and related
proprietary software and that Real Networks' use of the same mark on the goods
specified in its application is likely to cause confusion. The parties are
currently engaged in negotiations to resolve the dispute and various related
issues, including the proposed assignment to Real Media of various domain name
registrations, including adstream.com and mediaexpress.com.

"Innovation on the Internet" filed an application to register ADSTREAMS for
internet advertising, but has since abandoned the application.

Digital Business Resource, Inc. ("DBR"), a small value added reseller ("VAR")
company, has a pending application to register ADSTREAM for "a digital,
downloadable, computer-based messaging device" - namely a software application
that stores and transmits audio advertisements into convenience stores and gas
stations and tracks the play times. Real Media has not opposed DBR's application
even though Real Media has a priority of use, believing that DBR's use will not
pose a significant threat of confusion among Real Media's clients, online media
publishers.<PAGE>   1

                the application of Real Networks, Inc. (f/k/a Progressive
                Network, Inc.) to register REAL MEDIA as a trademark for
                "computer software which allows the viewing and transmitting of
                picture and/or video and/or text segments and audio segments
                over global information networks that transfer and disseminate a
                wide range of information." The use has been limited to a naming
                protocol for its software architecture. In its Notice of
                Opposition, Real Media has asserted that it has prior rights in
                the mark REAL MEDIA in connection with its on-line advertising
                services and related proprietary software and that Real
                Networks' use of the same mark on the goods specified in its
                application is likely to cause confusion. The parties are
                currently engaged in negotiations to resolve the dispute and
                various related issues, including the proposed assignment to
                Real Media of various domain name registrations, including
                adstream.com and mediaexpress.com.

                "Innovation on the Internet" filed an application to register
                ADSTREAMS for Internet advertising, but has since abandoned the
                application.

                Digital Business Resource, Inc. ("DBR"), a small value added
                reseller ("VAR") company, has a pending application to register
                ADSTREAM for "a digital, downloadable, computer-based messaging
                device" - namely a software application that stores and
                transmits audio advertisements into convenience stores and gas
                stations and tracks the play times. Real Media has not opposed
                DBR's application even though Real Media has a priority of use,
                believing that DBR's use will not pose a significant threat of
                confusion among Real Media's clients, online media publishers.
