2005 GMAC AFSA Investor Conference May 17, 2005 Sanjiv Khattri Executive Vice President & Chief Financial Officer

GMAC Safe Harbor In the presentation that follows and in related comments by General Motors Acceptance Corporation's management, our use of the words "expect", "anticipate", "project", "estimate", "forecast", "objective", "plan", "goal", "outlook", "target", "pursue" and similar expressions is intended to identify forward looking statements. While these statements represent our current judgment on what the future may hold, and we believe these judgments are reasonable, actual results may differ materially due to numerous important factors that are described in GMAC's most recent report on SEC Form 10-K, which may be revised or supplemented in subsequent reports on SEC Forms 10-Q and 8-K. Such factors include, among others, the following: changes in economic conditions, currency exchange rates, significant terrorist attacks or political instability in the major markets where we operate; changes in the laws, regulations, policies or other activities of governments, agencies and similar organizations where such actions may affect the production, licensing, distribution or sale of our products, the cost thereof or applicable tax rates; and the threat of terrorism, the outbreak or escalation of hostilities between the United States and any foreign power or territory and changes in international political conditions may continue to affect both the United States and the global economy and may increase other risks. Use of the term "loans" describes products associated with direct and indirect lending activities of GMAC's global operations. The specific products include retail installment sales contracts, loans, lines of credit, leases and other financing products. The term "originate" refers to GMAC's purchase, acquisition or direct origination of various "loan" products. 2
