Smith, Chairman Hughes Electronics Corporation 7200 Hughes Terrace Westchester, CA. 90045-0066 Fax No. 310-417-2840 Dear Mr. Smith: A number of people have told us that, in the teleconference you conducted yesterday to solicit shareholder consents from Hughes employees, you made several statements regarding my firm, including that (i) my firm is short ordinary GM common stock, (ii) as such we stand to gain financially by a drop in the price of ordinary GM common stock, and (iii) we are betting that ordinary GM shares will drop in price if the 120% Provision in GM's charter is honored rather than (as GM seeks) abrogated. You also reportedly stated during the teleconference that my firm has lost money by shorting ordinary GM shares and that our opposition to GM's pending proposal is simply motivated by our resulting disgruntlement. Your statements were false, and you had no basis for making them. We are not now, and at no point during the solicitation process have we been, short ordinary GM shares. Nor have we lost money by shorting ordinary GM shares. We therefore make the following demand of you personally, of Hughes Electronics Corporation, and (by copy of this letter to GM's general counsel) of GM: Immediately (i) retract in writing the foregoing misstatements; (ii) disseminate that retraction to all Hughes employees (whether or not they attended yesterday's teleconference); (iii) advise all Hughes employees that they have the right to change their vote, and provide them with the form and adequate time for doing so; (iv) provide us with copies of the foregoing material; and (v) if you or others acting on behalf of GM have made similar misstatements to any other persons, take appropriate steps to rectify that error and provide us with all materials used for that purpose. Please let us know by noon on Monday, December 8, whether and when you will be complying with this demand. The foregoing is without prejudice to any other relief available to us. Very truly yours, Mark D. Brodsky Portfolio Manager cc (by fax and FedEx): Thomas A. Gottschalk, Esq. Senior Vice President and General Counsel General Motors Corporation 3031 W. Grand Boulevard Detroit, MI 48202-3091 Fax 313-556-5108
