                         GMAC Credit Ratings Upgraded
                         ----------------------------



On April 23, 1998 Moody's  Investors  Service,  Inc.  (Moody's),  raised certain
credit ratings of the Company and its parent, General Motors Corporation (GM).

The Moody's  rating of the  Company's  senior debt was  upgraded  from A3 to A2,
seventh  and  sixth  highest  among  ten  investment  grade  ratings  available,
respectively.  The A2 rating is assigned to the bonds  considered to have "upper
medium grade" quality as they possess many favorable investment  attributes with
security factors for principal and interest considered to be adequate.

The Company's short term rating,  which was upgraded to Prime-1 on May 30, 1995,
remains unchanged.

The Company is pleased with the  upgraded  ratings as it expects to benefit from
enhanced financial flexibility and lower borrowing costs.

The Company is presently  not under review by any of the  nationally  recognized
statistical rating agencies. Additional disclosures regarding credit ratings are
provided on Pages 15 and 16 of the Company's  Annual Report on Form 10-K for the
year ended December 31, 1996, filed with the Commission on March 17, 1998.
