ITEM 2.06  MATERIAL IMPAIRMENTS

With respect to Form 8-K, Item 2.06, Material Impairments:

(a)   In connection with the preparation of General Motors Corporation's (GM)
      financial statements for the year ended December 31, 2004 and
      GM's 2005 budget and business plan process, GM reviewed the
      carrying value of its long-lived assets held and used, other than
      goodwill and intangible assets with indefinite lives.  This
      review is performed using estimates of future cash flows.  If the
      carrying value of a long-lived asset is considered impaired, an
      impairment charge is recorded for the amount by which the
      carrying value of the long-lived asset exceeds its fair value.
      As a result of this review, GM's management determined that
      charges for impairments of various assets were required as of
      December 31, 2004.  These assets are:
        i.  GM's remaining investment in Fiat Auto S.p.A. (Fiat Auto); and
        ii. Assets primarily related to certain product lines.

(b)   The amounts of the impairments are:
        i.  $220 million pre-tax ($136 million after tax) for GM's
            investment in Fiat Auto; and
        ii. $609 million pre-tax ($383 million after tax) for assets
            primarily related to certain product lines. Additional charges
            will be recognized in connection with previously announced
            actions with respect to GM's Baltimore, Maryland and Linden,
            New Jersey plants.

(c)   These impairments will not result in future cash expenditures.
