ITEM 8.01.  OTHER EVENTS

On Dec. 15, 2004, General Motors  Corporation (GM) contributed  approximately 11
million  shares of XM Satellite  Radio  Holdings Inc. (XM) Class A common stock,
into a trust established primarily to pre-fund health-care expenses for its U.S.
hourly retirees.

The stock, which was valued by an independent appraiser at approximately $419
million at the time of the contribution, will be added to the Voluntary
Employees' Beneficiary Association (VEBA) trust established to pre-fund part of
GM's other postretirement employee benefits (OPEB) liability related primarily
to health-care expense. Total assets in the VEBA trust were approximately $16.0
billion at Sept. 30, 2004. GM's gross OPEB liability, when last officially
reported on Dec. 31, 2003, was $67.5 billion.

Before the contribution, GM owned approximately 16.5 million shares of XM Class
A common stock and preferred convertible stock. GM now holds approximately 5.6
million shares of XM common stock, including shares convertible into common
stock. GM will retain a seat on the XM board of directors.

The contribution of the XM stock to the VEBA trust was determined to be an
appropriate and timely opportunity to utilize a GM-held asset to help address
the impact of rising health-care costs for retirees. GM continues to place a
high value on its business relationship with XM Radio, which supplies
satellite-radio subscription services made available by GM on more than 50
vehicle models sold in the United States.

The gain on this transaction, to be disclosed at a future date, will be handled
as a special item in GM's 2004-calendar year financial results.
