 Report of Independent Accountants We have examined managements assertion, included in the accompanying Report of
Management on Compliance with Specified Key Alternative Loan Program
Requirements, that Great Lakes Educational Loan Services, Inc. (Great Lakes) complied
with the specified requirements of the Subservicing Agreement (KeyCorp Student Loan
Trust 1999-B) between Key Bank USA, National Association and Great Lakes dated as
of September 1, 1999, as amended (Subservicing Agreement) during the year ended
December 31, 2004. Management is responsible for Great Lakes compliance with those
requirements. Our responsibility is to express an opinion on managements assertion
about Great Lakes compliance based on our examination. Our examination was conducted in accordance with attestation standards established by
the American Institute of Certified Public Accountants and, accordingly, included
examining, on a test basis, evidence about Great Lakes compliance with those
requirements and performing such other procedures, as we considered necessary in the
circumstances. We believe that our examination provides a reasonable basis for our
opinion. Our examination does not provide a legal determination on Great Lakes
compliance with specified requirements. In our opinion, managements assertion that Great Lakes complied with the
aforementioned requirements during the year ended December 31, 2004, is fairly stated,
in all material respects. /S/ ERNST & YOUNG LLP January 7, 2005
