In connection with the proposed transactions, General Motors Corporation ("GM"),
Hughes Electronics Corporation ("Hughes") and EchoStar Communications
Corporation ("EchoStar") intend to file relevant materials with the Securities
and Exchange Commission, including one or more Registration Statement(s) on Form
S-4 that contain a prospectus and proxy/consent solicitation statement. Because
those documents will contain important information, holders of GM $1-2/3 and GM
Class H common stock are urged to read them, if and when they become available.
When filed with the SEC, they will be available for free at the SEC's website,
www.sec.gov, and GM stockholders will receive information at an appropriate time
on how to obtain transaction-related documents for free from GM. Such documents
are not currently available.

GM and its directors and executive officers, Hughes and certain of its officers,
and EchoStar and certain of its executive officers may be deemed to be
participants in GM's solicitation of proxies or consents from the holders of GM
$1-2/3 common stock and GM Class H common stock in connection with the proposed
transactions. Information regarding the participants and their interests in the
solicitation was filed pursuant to Rule 425 with the SEC by EchoStar on November
1, 2001 and by each of GM and Hughes on November 16, 2001. Investors may obtain
additional information regarding the interests of the participants by reading
the prospectus and proxy/consent solicitation statement if and when it becomes
available.

This communication shall not constitute an offer to sell or the solicitation of
an offer to buy, nor shall there be any sale of securities in any jurisdiction
in which such offer, solicitation or sale would be unlawful prior to
registration or qualification under the securities laws of any such
jurisdiction. No offering of securities shall be made except by means of a
prospectus meeting the requirements of Section 10 of the Securities Act of 1933,
as amended.

an inability to obtain certain retransmission consents; (9) an inability to
retain necessary authorizations from the FCC; (10) an increase in competition

television services; (11) the introduction of new technologies and competitors
into the subscription television business; (12) changes in labor, programming,
equipment and capital costs; (13) future acquisitions, strategic partnership and
