                     SUPPLEMENTAL PROXY SOLICITING MATERIAL

            IN CONNECTION WITH THE CORPORATION'S 2003 ANNUAL MEETING

                           SCHEDULED FOR JUNE 3, 2003

Stockholders of General Motors Corporation ("GM") entitled to vote at GM's 2003
Annual Meeting are asked to vote in support of the recommendations of the Board
of Directors for the reasons set forth in the Proxy Statement which was
distributed to stockholders together with the notice of the meeting and on the
basis of the information provided below.

   WE EMPHASIZE THE NEED TO CONSIDER GM'S PROGRESSIVE CORPORATE GOVERNANCE IN
                    RELATION TO VOTING ON ITEM NO.S 6 AND 7
                              * * * * * * * * * * *

             GENERAL STATEMENT REGARDING CORPORATE GOVERNANCE AT GM

A.   For more than 10 years GM has maintained in policy and in practice a
     majority of independent directors (currently the Board has determined that
     only one of 10 (the Chairman & CEO) is not independent). "Independence" is
     defined by GM's By-Laws and in accordance with that definition determined
     annually by GM's full Board of Directors as to each member of the Board.
     The definition and process is consistent with the rules of the NYSE and
     those promulgated under Sarbanes-Oxley.

B.   GM's Corporate Governance Guidelines were a model when first adopted and
     published nearly 10 years ago and they have been periodically updated on
     GM's website, including as recently as May 16, 2003, to demonstrate the
     commitment of GM's Board of Directors to maintaining up-to-date principles
     of governance reflecting the recent Sarbanes Oxley legislation and proposed
     NYSE governance guidelines.

C.   Every Committee of GM's Board consists exclusively of independent
     directors.


D.   GM does not have a staggered board - all directors are elected annually

E.   GM has confidential voting.

F.   GM has no stockholder rights plan ("poison pill"). The Corporation's proxy
     statement indicates that if GM did adopt a stockholder rights plan it would
     include a TIDE provision (Three-year Independent Director Evaluation of
     retention or withdrawal of the plan), and on May 15, 2003, GM filed a
     statement with the SEC indicating that if GM's Board ever did adopt a
     poison pill it would be submitted to stockholder vote within 12 months.

G.   GM stockholders do have the right to act by written consent.

H.   GM has made available to its stockholders a description of the process by
     which they may submit director nominees (i.e., in Article 2.11 of GM's
     By-Laws, which are on GM's website - and annually in GM's Proxy Statement).

I.   GM does not have an excessive number of directors. The Board's Governance
     Guidelines reflect the view that 10-14 is the optimum number of directors
     for GM.

J.   GM's dual-class common stock capital structure is not the type of
     dual-class structure, which is abusive or otherwise disenfranchises any
     group of GM stockholders - with the structuring having been repeatedly
     approved by substantial majorities of both classes of GM common
     stockholders.

K.   GM has announced the  execution of definitive  agreements  among GM, Hughes
     and The News Corporation Limited,  pursuant to which GM's dual-class common
     stock  structure  will be eliminated as a result of  transactions  in which
     Hughes  would be  split-off  from GM and GM's  Class H  stockholders  would
     receive  Hughes common stock in exchange for their Class H stock  (tax-free
     for U.S.  Federal  income tax  purposes)  and in exchange for some of those
     shares of Hughes, some American Depositary Receipts representing  Preferred
     American Depositary Shares of The News Corporation Limited and or cash. The
     foregoing is subject to approval by GM stockholders,  regulatory clearances
     and  satisfaction  of the terms of the  definitive  agreements  between the
     parties as filed with the SEC and available on EDGAR.

L.   GM has stated in its Proxy Statement the commitment of management to
     terminate all existing consulting engagements with Deloitte Consulting by
     year-end and to not initiate any new engagements with Deloitte Consulting.

M.   GM's 2002 payments of fees to its independent  auditor,  Deloitte & Touche,
     included fees "other than audit, audit related and tax fees" which exceeded
     audit and audit related fees principally  because consulting  services were
     performed by Deloitte & Touche for Hughes  which  improved the accuracy and
     reliability  of the  process  by which  the  number of  subscribers  to the
     DIRECTV service of Hughes is determined.  That number is reported  publicly
     by Hughes on a regular basis in conjunction  with its earnings  releases to
     provide a highly useful indicator of the business performance of DIRECTV to
     investors in Class H stock and the public markets. While that number is not
     an "audited"  number,  its  significance to investors in GM common stock is
     deemed highly  important and,  thus, the consulting  work was regarded as a
     true service to GM investors.

                 LEGENDED IN ACCORDANCE WITH SEC REGULATION M-A

In connection with the proposed transactions relating to Hughes which are
referred to above, General Motors Corporation ("GM"), Hughes Electronics
Corporation ("Hughes") and The News Corporation Limited ("News") intend to file
relevant materials with the Securities and Exchange Commission ("SEC"),
including one or more registration statement(s) that contain a prospectus and
proxy/consent solicitation statement. Because those documents will contain
important information, holders of GM $1-2/3 common stock 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 (along with any other documents and
reports filed by GM, Hughes or News with the SEC) 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 and Hughes and certain of its
executive officers may be deemed to be participants in the 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 about the
directors and executive officers of GM and their ownership of GM stock is set
forth in the proxy statement for GM's 2003 annual meeting of shareholders.
Participants in GM's solicitation may also be deemed to include those persons
whose interests in GM or Hughes are not described in the proxy statement for
GM's 2003 annual meeting. Information regarding these persons and their interest
in GM and/or Hughes was filed pursuant to Rule 425 with the SEC by each of GM
and Hughes on April 10, 2003. Investors may obtain additional information
regarding the interests of such 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 any securities, 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.
