Preliminary 2008 First Quarter Results

Forward Looking Statements

1

In this presentation and in related comments by our management, our use of the words “expect,”“anticipate,” “estimate,” “goal,” “target,” “believe,” “improve,” “intend,” “potential,” “continue,” “designed,”“opportunity,” “risk,” “may,” “would,” “could,” “should” or similar expressions is intended to identify forward-looking statements that represent our current judgment about possible future events. We believe these judgments are reasonable, but these statements are not guarantees of any events or financial results, and our actual results may differ materially due to a variety of important factors. Such factors include, among others: our ability to realize production efficiencies, to achieve reductions in costs and to implement capital expenditures at levels and times planned by management; market acceptance of our products; shortages of and price increases for fuel; significant changes in the competitive environment and the effect of competition in our markets, including on our pricing policies; our ability to maintain adequate liquidity and financing sources and an appropriate level of debt; labor strikes or work stoppages at our facilities or at our key suppliers; financial difficulties of our key suppliers; adoption of new laws or changes in existing laws that may affect the production, licensing, distribution, cost or sale of our products; the final results of investigations and inquiries by the SEC; court approval of the settlement agreement with the UAW and UAW retirees related to the 2007 National Agreement; satisfaction of the conditions to the effectiveness of the post-retirement healthcare benefit plan contemplated by the 2007 National Agreement; changes in economic conditions, commodity prices, currency exchange rates or political stability in the markets in which we operate; possible downgrades for GMAC or ResCap by rating agencies; GMAC’s inability to maintain adequate financing sources for its capital needs; and recent developments in the residential mortgage market, especially in the nonprime sector.

The most recent reports on SEC Forms 10-K, 10-Q and 8-K filed by us or GMAC provide information about these and other factors, which may be revised or supplemented in future reports to the SEC on those forms.

First Quarter Operational Highlights

2

• Global market share of 12.5%, down 0.5 p.p. vs. Q1 2007

• Record GM sales in 3 of 4 regions driven by emerging markets growth

• Total automotive revenue of $42.1B, about flat as decline in North America offset growth in all other regions

• Improved adjusted automotive earnings before tax– Unfavorably impacted by American Axle strike, but favorable

offsets in commodity hedging and foreign exchange

• GMNA operations showed continued cost performance– Approximately $0.5B of year-on-year structural cost savings

related to manufacturing and people cost– Material costs lower despite significant commodity headwinds

• Q1 gross automotive liquidity of $23.9B

American Axle Strike

3

• Through end of Q1, GMNA incurred production losses related to American Axle strike of approximately 100k units– Majority of impact is to full-size pickups and utilities, although also

impact full-size vans and midsize trucks– Q1 financial impact of approximately $0.8B EBT

• To date, strike has had minimal impact on GM’s ability to meet customer demands

• GM will continue to proactively manage schedules across plants to maintain production to the extent possible

First Quarter Financial Highlights

• GAAP net loss of $(3.3)B, $(5.74) EPS

• Adjusted automotive earnings before tax (EBT) of $0.4B, up $0.2B vs. Q1 2007 (excluding Allison results)

• Adjusted net loss of $(350) million, $(0.62) EPS, excluding special items

GMAC Impairment

18

• U.S. GAAP states that a loss in value of an investment that is other than temporary should be recognized

• GM conducted analysis to determine if there is impairment of our GMAC equity investment based on fair value

– Based on current market conditions, indicated value of common equity interest is $1.31B less than previous carrying value of $6.7B• Driven by estimated market value of ResCap using market multiples of

mortgage companies– Current market pricing also indicates value for preferred equity

interest is $0.14B less than previous carrying value of $1.0B

• GM recorded Q1 non-cash charges totaling $1.45B to impair both common and preferred equity interests

– Current GM carrying values for common and preferred interests now $5.4B and $0.9B, respectively

GM Liquidity Position

19

• Liquidity position of $23.9B at March 31, 2008– Includes $0.7B of readily-available VEBA assets (i.e. short-term

VEBA)– Represents decrease of $(3.4)B from year-end 2007

• Reflects negative adjusted automotive OCF driven primarily by lower Q1 production in GMNA, including impact of American Axle strike

• Additionally have access to about $7B of undrawn, committed U.S. credit facilities

– Total available liquidity of over $30B at the end of Q1

• Net liquidity of $(16.2)B, $(4.1)B lower than year-end 2007 resulting from lower Q1 2008 cash balance

First Quarter Key Cash Flow Drivers

21

• Q1 2008 adjusted automotive OCF of $(3.6)B– Net OCF impact of American Axle strike estimated at

approximately $(2.1)B for the quarter, $(1.3)B of which was related to managed working capital and accrued expenses

• Q1 2008 OCF unfavorable by $(3.8)B vs. Q1 2007 due primarily to:

– Unfavorable working capital variance– Higher capital expenditures– Lower sales allowance accruals and slightly higher payments

U.S. Industry Outlook

24

• U.S. economy is facing strong headwinds

• Aggressive monetary policies have reduced risk of a credit crunch; however with side effects of weakening dollar and surging oil prices

• Short-term industry conditions remain very challenging

• GM is revising its outlook for 2008 U.S. total industry outlook to the mid-to-high 15 million unit range

• Will continue to monitor closely, noting that some positive signs are evident

– Outside of housing, autos and finance, employment and investment are holding up

– Signs that housing activities may soon stabilize, albeit at low levels

Operating Actions – GM North America

25

• Aligning capacity with demand– Eliminated one shift of production at three full-size pickup truck

plants and one full-size utility plant– Continue to work on successful implementation of hourly attrition

program and 2007 UAW contract

• Aligning inventory with demand– Full-size pickup and utility inventory reduced - - consistent with

market demand– Total U.S. dealer inventory at end of April (estimated to be ~840k)

at lowest April-ending level since 1983

• Maximize success of recent new products

• Continue to deliver successful new products to the marketplace

Growth Strategies – Emerging Markets

26

• Grow quickly and profitably in fastest growing markets

• Expand capacity in cost effective manner– New assembly plants in Russia, India and Mexico– New powertrain plants in Mexico, China and Brazil– Working with partners to increase capacity– Evaluating longer-term capacity increases

• Expand “lower cost” product portfolio

• Strong focus on brand building and distribution channels

Growth Strategies – GMLAAM Example

27

• Adding assembly capacity in Mercosur region– Shifts, line rate increases

• Adding assembly capacity in Andean region– Line rate increase in Colombia– Contracted assembly in Venezuela and Ecuador

• Adding flex fuel powertrain capacity in Brazil

• Distribution improvements in the Middle East

• Leveraging GM’s global portfolio and manufacturing footprint

Delphi Update

28

• Delphi unable to emerge under its Plan of Reorganization, as Plan Investors terminated their investment agreement on April 4

– GM-Delphi Settlement Agreements and agreements with Delphi’s labor unions remain in place but are not generally effective

• GM will agree to advance up to $650M to Delphi during 2008 in anticipation of effectiveness of the GM-Delphi Settlement Agreements

– Within amount GM would have paid had Delphi emerged from bankruptcy– Would be concurrent with Delphi DIP extension– GM would receive an administrative claim for advances

• GM continues to work with Delphi and its stakeholders to facilitate Delphi’s efforts to emerge from bankruptcy

• Q1 charge of $0.7B primarily results from updated estimates reflecting uncertainty around nature, value, and timing of GM’s recoveries

– Total of $8.3B in net Delphi-related charges taken to date

Outlook• Second Quarter

– Volume and revenue growth overseas, particularly in key emerging markets

– Manage GMNA business in a more challenging environment

– Execute North American capacity actions

– Actively manage special risk factors (Delphi, GMAC / ResCap, American Axle)

• Looking Ahead– Strong focus on managing business for cash flow

– Begin to see impact of current Special Attrition Program

– Execute key launches such as Chevrolet Traverse in North America and Opel Insignia in Europe

– Bring new capacity on-line in Mexico, Russia and India
