Filed by General Motors Corporation Subject Company - General Motors Corporation and Hughes Electronics Corporation and EchoStar Communications Corporation Pursuant to Rule 425 under the Securities Act of 1933 and Deemed Filed Pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Commission File No.: 333-84472 E-News Merger Update Message to DIRECTV Employees Distribution: DIRECTV USA Subject: Merger Update As part of the DIRECTV senior leadership team's commitment to increase the frequency of merger updates to employees, the following information is the first of many brief snapshots of what's currently happening with the merger approval process and transition planning efforts. Recently, DIRECTV and EchoStar senior executives began a series of merger planning and transition meetings. Ultimately, these meetings will be used to create a business plan for the new company, which will help guide the transition planning. Currently, the Department of Justice (DOJ) is reviewing the merger along with the Attorneys General of a number of states to ensure it complies with antitrust laws. EchoStar and HUGHES are confident that both the DOJ and the state Attorneys General will find that the relevant market includes satellite TV and cable TV and does not violate antitrust laws. The Federal Communications Commission (FCC) also plays a significant role in the merger approval process. It must approve the transfer of the FCC licenses held by HUGHES and EchoStar to the merged company. HUGHES and EchoStar filed responses with the FCC on Feb. 25 to issues raised in third-party objections to the two companies' application for transfer of control. They also filed an application for a new satellite to implement the "Local Channels, All Americans" plan, which was announced by HUGHES CEO Jack Shaw, DIRECTV Chairman and CEO Eddy Hartenstein, and EchoStar Chairman and CEO Charles Ergen, on Feb. 26. The FCC submitted a number of merger-related questions and requests for documents to HUGHES and EchoStar. HUGHES and EchoStar submitted a partial response to the FCC's requests on March 6. HUGHES and EchoStar also submitted a voluminous response to the FCC's Information Request on March 21. Eddy and Charlie testified before the U.S. Senate Judiciary Committee's Subcommittee on Antitrust on March 6. This was the third Congressional hearing discussing the merger. As part of their testimony, Eddy and Charlie described the consumer benefits of the merger, including the "Local Channels, All Americans" plan. * * * E-News is your resource for news about DIRECTV and parent companies HUGHES and GM.
